With the rapid development of the automobile industry, the market and consumers are becoming more and more mature. For the matter of buying a car, everyone has not only paid attention to the brand, price and appearance, but also factors such as quality are becoming the focus of consumers’ attention. After all, no one wants to always run to a 4S shop after buying a car, or even stop on the road to wait for help.

　　Word-of-mouth communication is very important on quality issues, and reports issued by professional organizations are also a great reference for consumers. A few days ago, J.D. with high credibility. Power America’s 2020 new car quality survey report was released. It is not surprising that Tesla’s new car quality ranks at the bottom due to the lack of maturity in building cars. However, it is also not surprising that Land Rover, which was ridiculed by everyone as "not repaired well", really appeared in the penultimate position of new car quality, and its brother brand Jaguar ranked sixth from the bottom.

　　In China, Jaguar Land Rover is also facing the same situation, with endless quality problems and repeated complaints from users. Judging from the public information of Chezhi. com, Jaguar Land Rover was complained 108 times in the first half of this year, most of which were quality problems. Of course, there were also complaints about sales fraud and poor service attitude. As of press time, Jaguar Land Rover has not made a public statement on all faults.

　　Judging from the specific models, Land Rover found that Shenxing became the most complained model of Jaguar Land Rover in the first half of this year, reaching 43 times, accounting for nearly 40% of the total complaints. Complaints about the discovery of Shenxing mainly focus on the engine, including water pump failure, abnormal sound, antifreeze leakage, flameout and so on.

　　Just in late March of this year, it was found that Shenxing had been "delisted" by Land Rover, and the sports version was found instead. In fact, it was found that Shenxing’s redesigned model could be "transshipped" by changing its name, but the most important thing is to improve the quality control level.

　　Long-standing quality problems have killed Jaguar Land Rover’s brand strength and product strength to a certain extent. Now, it can only compete with other brands with preferential margins ranging from 40,000 to 50,000 to more than 100,000. Although the price reduction of luxury cars is a common phenomenon, brands such as Lexus still exist, and excellent product quality is the foundation of Lexus. Jaguar Land Rover should really reflect on it.

　　In the complaints about Jaguar Land Rover’s quality problems in the first half of this year, a series of engine failures became the biggest problem, such as engine water pump failure, abnormal sound, flameout, jitter, antifreeze leakage and crankshaft failure, which can be described as frequent problems.

　　As we all know, the engine is one of the core parts of the car, and it is the heart of the car, which determines the performance of the car. However, there are many quality problems in such an important part, which is naturally unacceptable to users.

　　According to users’ complaints, the trouble of Jaguar Land Rover engine is mainly concentrated on the 2.0T turbocharged engine with model PT204, which is currently installed on Land Rover Discovery, Land Rover Discovery Sport Edition, Land Rover evoque, Jaguar XEL, Jaguar F-PACE and other models.

　　As far as fault classification is concerned, the number of complaints about engine water pump fault is the highest, and the water pump fault has also caused a series of chain reactions. The water pump fault leads to insufficient cooling of the engine, and the cooling fan will always run at a high speed, which will produce a lot of noise. Some users complain that the abnormal noise of the engine is caused in this way. In addition, the high-speed operation of the cooling fan will also cause engine jitter, which will even be transmitted to the steering wheel according to users’ feedback.

　　Some users said that although they knew it was a water pump problem, they were told to wait for accessories after arriving at the 4S shop. At the same time, the staff also said that it would not affect the normal use. In the eyes of users, this is obviously irresponsible. "So many vehicles have the same problem, which is obviously a common problem. Jaguar Land Rover should be recalled, but now it is unacceptable to just let us wait." One user said this.

　　In addition to the water pump problem, there are not a few complaints about engine flameout. Some car owners said that the 2017 Land Rover they bought found that Shenxing engine flameout frequently when braking or starting in April this year, and reported that "special procedures were closed", and the fault still existed after one week of repair.

　　Another user pointed out that on April 28, he was driving a 2017 Jaguar XFL car at a high speed, and suddenly the engine fault light came on, followed by abnormal noise, jitter, smoke and flameout of the engine. After dragging the car to a 4S shop, the engine needed to be replaced.

　　The engine flameout has risen from a quality problem to a safety problem. After the engine flameout, the braking power and steering power will disappear, and the driver’s improper operation will cause accidents, especially on the expressway, which is very easy to cause rear-end accidents. Safety is the bottom line. Jaguar Land Rover must pay enough attention to it, and the safety of drivers and passengers must be put in the first place. Faults such as engine flameout must be solved promptly and effectively.

　　According to the summary of complaints from Jaguar Land Rover, besides the engine, the quality problems of its products can’t be overemphasized, such as oil leakage from transmission, frustration, abnormal sound of car body, resonance, foaming and cracking of paint, water leakage, abnormal sound of brake system, cracked glass, mailbox defect (jumping gun) and so on. After buying Jaguar Land Rover’s car, it is really difficult for users to feel at ease and worry.

　　Judging from the number and content of complaints, transmission oil leakage is also one of the common quality problems of Jaguar Land Rover’s products. Some users said that the transmission oil leakage occurred when the new car they bought was driven less than 5,000 kilometers, which made some car owners unacceptable. Transmission oil leakage is still a chronic disease. One car owner has repaired the transmission oil leakage five times since he bought the car in March 2017, but the problem has never been completely solved.

　　Of course, there are also some 4S shops that don’t take the oil leakage of the transmission seriously. Clean up the surface and let the owners go home to observe it. However, the oil leakage of transmission is not small, which will lead to insufficient lubrication and accelerate the friction between gears. However, when the size is in a dry friction state for a long time, it will lead to gear damage and the transmission will be scrapped. Therefore, the oil leakage of transmission should be highly valued by car owners, 4S shops and manufacturers.

　　Among many complaints from users, low-frequency resonance has attracted our attention. Most of this complaint is directed at Land Rover Range Rover Star Pulse, but generally speaking, automobile products receive less such complaints. Some car owners said that when the vehicle is driving on a bumpy road, or the engine speed is between 1100 and 1500, whether driving or parking, the low-frequency resonance in the car is serious, and there is a strong ear-pressing feeling, which affects driving safety.

　　In fact, it is simply understood that low-frequency resonance is like flying, with high internal pressure and buzzing in the ear. The feeling of low-frequency resonance varies from person to person, and sensitive people will have adverse reactions such as headache and palpitation, which will affect normal driving. Jaguar Land Rover should pay full attention to this potential safety risk. However, judging from the complaints of car owners, Jaguar Land Rover has not effectively solved the problem of low frequency resonance.

　　For Jaguar, which is located in luxury, and Land Rover, which focuses on luxury all-terrain SUVs, there are many quality problems mentioned above, especially the core components, and some failures can’t be cured for a long time, which is really difficult to support the word "luxury". And consumers’ eyes are discerning. If this continues, I believe that its few clusters will be further reduced. Of course, this can’t blame the fierce competition, but Jaguar Land Rover’s own inaction.

Every complaint you make and every suggestion on consumption may change the world. Please go to the black cat to complain: [click on the complaint]

　　Hot topics in Weibo this week revolved around new cars, energy issues and the resumption of production under the current epidemic situation. On Friday, domestic refined oil prices dropped sharply for the first time this year, and 95 # gasoline fell back to 8 yuan level again. At the same time, many car companies and factories such as Weilai, Tesla and SAIC Volkswagen are trying to resume normal production. Facing the epidemic situation and the shortage of raw materials, it is a problem that all car companies have to face at present. In terms of new cars, we also saw the fashion-the official appearance of yachts, as well as the information declared by the Ministry of Industry and Information Technology of Ideal L9 and Question M7, "Good meals are not afraid of being late", so we will wait and see.

　　1. Networked Tesla Shanghai Factory will adopt closed-loop production mode.

　　Reading volume: 174,000

　　Event Review: Recently, an unnamed insider revealed that Tesla had telephoned its employees in Shanghai to prepare for the resumption of work next week. It is reported that Tesla informed some employees on Friday that the company will adopt a closed-loop production method on April 17, and employees will eat and live in the factory and conduct regular nucleic acid testing. Tesla will arrange a bus to return the employees who have been notified to the factory.

　　Netizens are hotly discussing:

　　Comments: At the center of the epidemic, all automobile enterprises and factories in Shanghai have been hit like never before. "If the supply chain enterprises in Shanghai and surrounding areas can’t find a way to dynamically resume work and production, all automakers in China may have to stop production in May." On April 14th, He Xiaopeng, the founder and chairman of Xpeng Motors, posted a dynamic in the circle of WeChat friends, pointing to the severe challenges facing the current automobile industry chain.

　　Prior to this, Weilai and Great Wall Motor tank brands have successively announced that due to the epidemic situation in Shanghai, Jiangsu and Jilin, the company’s supply chain partners have stopped working and stopped. Affected by this, it is forced to suspend the production of the whole vehicle, and the delivery of some vehicles will be delayed. Recently, the delivery cycle of mainstream models in the market has been extended, especially the delivery cycle of new energy vehicles is about 5~7 weeks, and even some models have to wait for 5 months.

　　However, in the face of the epidemic, there are always more ways than difficulties. On April 15, it was reported that SAIC promoted the resumption of work and production, and will start the stress test of resumption of work and production on April 18. On April 15th, the Ministry of Industry and Information Technology said that we should do our best to prevent and control the epidemic accurately, ensure smooth logistics and stabilize the industrial chain supply chain, take various measures to support the stable production of key enterprises in Shanghai, and concentrate resources to give priority to ensuring the resumption of production of 666 key enterprises in key industries such as integrated circuits, automobile manufacturing, equipment manufacturing and biomedicine.

　　Summer is coming, and everyone will overcome the difficulties together. When we meet again, it will be a more beautiful encounter.

　　Second, Dongfeng popular yacht debut

　　Reading volume: 1.5 million

　　Event Review: On April 15th, Dongfeng Fengxing’s brand-new yacht was officially unveiled. The new car is positioned as a 7-seat family car, focusing on young fashion. The design concept of "front dynamics" incorporates many yacht elements.

　　The length/width/height dimensions of the new car are respectively 4850/1900/1715mm, and the wheelbase is 2900mm. As a model featuring the concept of "daddy’s car", the popular yacht has remarkable performance in parameters, but it is not clear how the actual space performance is.

　　The interior style of the yacht is also intended to create a sense of warmth at home, and it is also equipped with a sometimes popular double screen, which looks very delicate as a whole.

　　According to the official pictures, the third row of seats can be laid down in proportion, which is very flat after being completely laid down. As a 7-seat car that is mainly used for home use, flexible space layout and seat comfort will also become very important selling points.

　　Comments: Dongfeng Fengxing is also regarded as one of the oldest independent car companies in China. Its products have always been famous for their durable leather, but they often need to be improved in design and details. The appearance of this yacht can still be seen from the design. Popular changes. However, there are still many experts in this level of domestic market segments, such as Wuling. It’s not easy for the popular yacht to achieve success in these days. As the first 7-seater family car after the brand rejuvenation of Dongfeng, it shoulders many expectations, and we also wish it good results.

　　Third, the ideal L9 Ministry of Industry and Information Technology declaration information release

　　Reading volume: 277,000

　　Event Review: The declaration information of Ideal L9 has been published. The ideal L9 is positioned in a large SUV, with a body size of 5218/1998/1800mm and an amazing wheelbase of 3120 mm.. In addition, the curb weight of the vehicle has reached 2520kg, and the total weight is 3120kg when it exceeds 3 tons. Even so, driven by its four-wheel drive, the acceleration time of the vehicle is only 5.3 seconds.

　　Comments: The information of the ideal L9 must be familiar to everyone. If it is not affected by the epidemic, you should be able to see the real car at this time.

　　As I said before, although Li ONE sells well, it is far from enough to have a better performance. Ideal L9 is very important, because it is a key link between the past and the future. Li ONE’s extended-range power was completely inherited, but he finally got a little sense. He abandoned the three-cylinder engine and exchanged it for the four-cylinder engine. At the same time, the latest configuration has been applied in many aspects such as battery life and intelligent configuration.

　　However, we also noticed several points. The curb weight of this ideal L9 reached 2520kg, and the total weight was 3120kg when it exceeded 3 tons. What can you think of when you see this data? My first reaction is that this is an out-and-out tank. That is to say, New Energy dares to play like this, but the ideal L9 is not a pure electric car. When the power is exhausted, what kind of driving experience is it for a 1.5T four-cylinder engine to deal with a large body of more than 2.5t.. According to the Ministry of Industry and Information Technology, the minimum fuel consumption is 7.8L/100km. Do you believe it? Try not to let it run out of electricity.

　　ONE thing is certain, the intelligent degree and related intelligent configuration of the ideal L9 is richer than that of the previous Li ONE, and the cockpit will bring a brand-new multi-person interactive entertainment experience, which should be more interesting, but we can’t make a clearer judgment until the actual car test drive.

　　Finally, what level of price will the ideal L9 set? At least 450 thousand, it shouldn’t be lower. How much do you think it can be set? Welcome to leave a message ~

　　Fourth, Tengshi MPV or DMI hybrid system

　　Reading volume: 563,000

　　Event review: Tengshi MPV really leaked, and the price was between 300,000 and 500,000. The new car adopts a 7-seat layout of 2+2+3, and the third row of seats can be leveled, giving consideration to practicality. As a medium and large MPV, its body length reaches 5m 2 and its wheelbase exceeds 3m. Tengshi MPV will provide pure electric and hybrid power models to choose from, equipped with BYD blade batteries. The hybrid mode will be equipped with BYD DM-i hybrid system, and the battery life is expected to reach more than 1000 kilometers.

　　Comments: At first glance, the front face of this Tengshi MPV is quite similar to that of Erffa, and some netizens pointed out that it is a showstopper. Let’s just think of it as a showstopper, so what is the strength and characteristics of this showstopper?

　　First of all, this Tengshi MPV includes DM and EV dual power modes, and the comprehensive battery life of the DM version can reach 1000km；; Two-wheel drive/four-wheel drive versions are also available. Super-hybrid technology adopts ultra-high thermal efficiency engine and EHS electric hybrid system, and the dual electronic control, dual motors, reducer and clutch are highly integrated. Compared with extended-range hybrid, there are more forms of engine direct drive, and the comprehensive torque of super-hybrid four-wheel drive system can exceed 600N.m

　　In addition, the pure electric high voltage technology of Tengshi MPV adopts 8-in-1 integrated intelligent precursor assembly, innovatively uses motor inductance to boost the voltage, and can realize the wide-range heat pump working temperature of -30~60℃.

　　Although BYD’s LOGO is not hung, everyone knows the relationship between Tengshi and BYD. As for the super hybrid and EV technology used in this car, it naturally originated from BYD. Not long ago, BYD just announced that it would stop producing fuel vehicles, and soon this Tengshi MPV made a high-profile appearance. And its price is also surprising, between 300,000 and 500,000. It seems that "showstopper" is really an appropriate name for it. Can it really make waves in the high-end new energy MPV market? Wait and see.

　　V. AITO’s declaration map of M7.

　　Reading volume: 3.17 million

　　Event Review: On April 15th, in the 355th batch of Announcement of Road Motor Vehicle Manufacturers and Products published by the Ministry of Industry and Information Technology, we were surprised to find the declaration drawing of the second model of AITO, and the new car was named as "Wenjie M7".

　　Netizens are hotly discussing:

　　Comments: In December 2021, which is not too far away from us, the M5 was officially released. It was listed in February this year and delivered in March. Just the day before yesterday, in the sales list of new energy SUVs released by the Ride Association in March, the M5 in the world has come to the 12th place, with sales exceeding 3,000 units. Now the second model has entered our field of vision, I wonder if its "speed" can exceed the M5?

　　What are the characteristics of this M7? Let’s take a brief look at it first:

　　The new car and the M5 have the same family design, and the whole car looks "simple+pure". The air intake grille, roof lines and penetrating head and tail lights are both imposing and exquisite. According to the new car declaration map, five-spoke and ten-spoke wheels will be provided in the future, as well as chrome-plated and pure black window trim strips, and privacy windows will be equipped.

　　The length, width and height of the new car are 5020/1945/1775mm and the wheelbase is 2820 mm. It is not difficult to see from the naming that this will be a larger model. The new car will adopt a 6-seat layout; The new car will also be equipped with a large-sized giant central control panel, which will once again highlight the advantages and technological sense of Huawei’s smart cockpit.

　　The new car will continue to be equipped with an extended range power system consisting of a 1.5T range extender and a motor. The battery is Contemporary Amperex Technology Co., Limited, and it is estimated that the maximum cruising range will once again exceed 1,000km. (Is it really this high? I don’t particularly believe it)

　　6. BMW CEO said that there is still a market for traditional fuel vehicles.

　　Reading volume: 670,000

　　Event Review: On April 15th, BMW CEO Oliver Zipse said that the company must be careful not to rely too much on a few countries and only focus on electric vehicles. He added that "there is still a market for traditional fuel vehicles".

　　Comments: This is another remark that attracts attention, and I can’t help but think of the sentence that Wei came to Li Bin last year, "I don’t understand why people are still buying oil cars." The pros and cons are sharp and targeted. At the recent 100-person forum on electric vehicles in China, experts also made it clear that oil cars and trams are not competitive for a long time. It is still too early to say that trams will replace oil cars. The reason is clear to all. Without more words to prove it, the market sales will give the answer.

　　There is no doubt that the development of pure electricity is the direction and future, but as Zips said, there is still a market for fuel vehicles, and there are still many people who like fuel vehicles. More should be complementary and cooperative.

　　No.7 and No.95 gasoline may fall back to the 8 yuan era.

　　Reading volume: 1.66 million

　　Event Review: At 24: 00 on April 15th, a new round of price adjustment window for domestic refined oil products will open. Based on the predictions of many institutions, the retail price of domestic refined oil products will usher in the first round of downward adjustment during the year. Since the beginning of this year, domestic refined oil prices have gone through six rounds of adjustment, with gasoline prices increasing by 1985 yuan/ton and diesel prices increasing by 1915 yuan/ton, showing a pattern of "six rises, zero falls and zero stranding", and 95 # gasoline in most areas of China has basically entered the "9 yuan era". If this round of downward adjustment is realized, the price adjustment of domestic refined oil products will be lowered for the first time in 2022, and 95 # gasoline is also expected to fall back to the 8 yuan era.

　　Comments: It is estimated that everyone will send out a feeling when they see the news of the downward adjustment of oil prices, "It’s not easy". No.95 gasoline has once again returned to the 8 yuan era, but the price reduction this time is not as good as the previous increase. For the vital interests of the people, the lower the better.

　　Some time ago, because the rising oil price also triggered the topic of whether to buy an electric car, I still remember that many people pointed out that the electricity bill for electric cars might not always rise, and the price of gasoline would not always fall. As soon as the voice fell, the fuel price was lowered. Although it remained in the high price range, it always gave people a break. However, it is difficult to charge electric vehicles, especially the popularization of basic charging piles in highways and remote areas, which is still a long way to go.

　　Eight, affected by the epidemic, tank 300 stopped production.

　　Reading volume: 1.467 million

　　Event Review: On the evening of April 13th, the tank brand issued a notice on its official App, saying that due to the epidemic situation in many places, a total of eight supplier partners were shut down and stopped. At present, due to this, the production of the tank 300 model was suspended from April 14th. Due to the above reasons, the delivery of the vehicles of the tank 300 users will be delayed.

　　Netizens are hotly discussing:

　　Comments: The hot sale of Tank 300 is obvious to all, but affected by the epidemic, this hot-selling model has to accept the dilemma of temporarily stopping production. The tank 500, which has just been listed, should also face the same problem. The automobile industry seems to be single, but in fact, the upstream and downstream related industrial chains are widely distributed. It is not an exaggeration to say that it is a pillar industry. I hope that the epidemic will end as soon as possible and return to normal. This is the top priority.

　　Automobile sales ranking in September and March

　　Reading volume: 770,000

　　Event Review: Recently, the Association released the latest retail sales data in March. The data shows that in March, the domestic narrow passenger car market sales reached 1.579 million units, down 10.5% year-on-year and up 25.6% quarter-on-quarter; From January to March, the cumulative sales volume was 4.915 million vehicles, down 4.5% year-on-year, and the overall sales trend was lower than expected.

　　Comments: As the saying goes, "more children fight", in March sales, BYD, the new energy vehicle company, was the biggest winner, with 7 cars and SUVs in the top 15. However, Wuling Hongguang MINI EV still ranks first with a slight advantage, and Tesla is only more than 2,000 vehicles away from it.

　　At the same time, according to the analysis of the Federation, due to the spread of the epidemic in different degrees in various parts of the country, the transaction volume in Jilin, Shanghai, Shandong, Guangdong, Hebei and other places has been affected, and the changes in the closure management in various places have an impact on the logistics efficiency of the whole vehicle and parts, resulting in a large loss of production and retail volume in key areas.

　　In March, self-owned brand car companies performed very well, with a market share of 48.5%, up 8.8 percentage points year-on-year. Compared with the hot sales of self-owned brands, the old joint venture car companies seemed to be unable to do so. Among them, the market share of German cars fell to 20%, Japanese cars fell to 20.9%, and the market share of American cars was less than 10%.

　　However, there are two points worthy of attention. The first one is the SUV sales ranking. Haval H6 was squeezed out of the top three, and Tesla MODEL Y, BYD Song and Changan CS75 ranked in the top three. Presumably, the Great Wall should be under great internal pressure and need to be dealt with as soon as possible. The second point is that in the B-class car camp, Changan Ford’s new Mondeo is officially listed, and the starting price of 159,800 yuan has once again lowered the production line of all joint venture brands. I wonder if this very attractive price can help Changan Ford achieve a perfect counterattack. I hope to see the new Mondeo in next month’s sales.

　　In order to maintain consistency, we set the speed of elk test at 72km/h, and locked it with speed limit function to maintain accuracy. From the subjective driving experience, there is not much difference in the overall driving experience of the chassis with and without the installation of the rear anti-roll bar.

　　In the original factory state, the front reaction of the vehicle when it enters the B area from the A area is still rapid. However, when the anti-roll bar was tested after installation, the response speed of the rear was obviously improved, but there was no obvious sliding or oversteer, and the overall trend was still biased towards understeer, but the response speed of the rear was faster.

●Beijing Institute of Technology-Researcher’s Conclusion (Elk)

　　The main purpose of this test is to compare the influence of rear anti-roll bar on vehicle handling performance. Through the test vehicles before and after installing the anti-roll bar, the elk test was carried out respectively. Collect data such as vehicle roll angle and yaw angle, and then analyze the influence of anti-roll bar installation or not on vehicle emergency lane change.

　　Because of the uncertainties such as the stability of driver’s input, the condition of vehicle tires, and the ground conditions of the site, each group conducted three experiments and finally took the average value. Each experiment is based on the fact that no bucket is touched and the sensor signal is valid.

●CarSim simulation analysis

　　Because there are many variables in this test, it is impossible to ensure the consistency of each experiment strictly, so it is necessary to analyze the control variables with the help of simulation. Through CarSim software, it can be achieved that the control variables are only the anti-roll bar, driver input, vehicle state, ground and other influencing factors, and they are strictly consistent.

　　In CarSim model, the vehicle with the anti-roll bar removed and the vehicle with the anti-roll bar installed were respectively set up to carry out the elk test and predict the test results. According to the test vehicle parameters, the CarSim simulation model is set up.The simulation results are shown in the following two pictures. The first picture shows the change trend of vehicle roll angle before and after installing anti-roll bar, and the second picture shows the change trend of yaw angle before and after installing anti-roll bar. The red line is the vehicle without anti-roll bar, and the blue line is the vehicle with anti-roll bar.

　　Above (simulation and prediction of roll angle)It can be seen that the roll angle curves are different in amplitude and change rate.

　　The yaw rate in the above picture (yaw angle simulation prediction) remains completely consistent. To some extent, it can be considered that the change of roll angle can reflect the influence on vehicle handling performance before and after installing anti-roll bar, and the difference of yaw angle may be caused by many factors, such as driver input.Therefore, in the analysis of the measured data, we should focus on the roll angle.

●Analysis of vehicle roll angle related data (the following two figures)

　　Vehicle roll angle data is collected by GPS inertial guidance gyroscope. The positive value of the collected data means that the left side of the vehicle is lifted, and the negative value means that the right side of the vehicle is lifted. In the elk test, the roll angle curves of all six experiments before and after installing the rear anti-roll bar.

　　It can be seen from the figure that in a single elk test, the roll angle changed three times. For the first time, after the vehicle entered Zone A, the steering wheel turned left and input, causing the vehicle to lean to the right. After the second vehicle enters the B area, the steering wheel changes from left to right, which causes the vehicle to shift its center of gravity and lean to the left with a fluctuation. The third time the vehicle entered Area C, it tilted to the right again due to inertia.

● Elk test-peak of roll angle (below)

　　By comparing the maximum change of the third roll angle before and after installing the anti-roll bar, we can reflect the change of the roll degree of the vehicle with or without the anti-roll bar. Define the vehicle roll angle as peak 1 when it reaches the peak for the first time, peak 2 when it reaches the peak for the second time, and peak 3 when it reaches the peak for the third time, and take all peaks as absolute values. The average value of the peak values of vehicle roll angle before and after installing the anti-roll bar is shown in the following figure.

Low center of gravity transfer rate (below)

　　There is a shift of center of gravity in the process of vehicle emergency lane change. During the center of gravity shift, the vehicle will roll from one side to the other. When the suspension stroke is compressed or the center of gravity is transferred, the vehicle roll angle will not change. Therefore, the time between two peak values of vehicle roll angle and the time of roll angle fluctuation after the vehicle enters Zone B can reflect the vehicle center of gravity transfer rate. It is defined that the interval between the first and second peak values of vehicles is T1, the fluctuation time of rear inclination angle in area B is T2, and the interval between the last two peak values is T3. Before and after the installation of the anti-roll bar, the center of gravity transfer time is shown in the following figure.

● Elk test conclusion

　　The data of milu deer roll angle has widened the gap in the limit state, which is also the most obvious project at present. The center of gravity transfer rate is understood according to the basic principle (which side is harder, it will be smoother).There is basically not much difference in the speed of the first handlebar direction (T1), but with the increase of the inertia of the vehicle changing lanes, the two center of gravity transfer rates of (T2, T3) are both faster with the rear anti-roll bar, but the gap between them is not obvious.Generally speaking, the follow-up and overall feeling of the rear are better, but the overall limit and driving characteristics of the vehicle have not changed much.

　　Through the four-column road simulation test-bed, the road surface conditions of daily vehicles can be restored on the test-bed.The test-bed can realize stable road excitation, avoid the influence of traffic conditions, route selection and weather environment in the actual road test, and minimize the instability in the test.

　　In this experiment, the light cross-country road spectrum is selected as the bench excitation input, which can restore the situation of poor road surface in daily urban use environment. Record the change of the roll angle of the test vehicle during the experiment. (as shown in the figure below)

More exciting videos are all on the car home video platform.

● Bench test conclusion

　　It can be seen from the figure that the inclination curves of the anti-roll bars are different, but considering that the absolute values of the inclination angles are all below 0.5 degrees. In daily use, the feeling is almost not great, so to some extent, it can be considered that whether to install the rear anti-roll bar has no significant influence on daily use.

●Test summary of BMW 325Li (Beijing institute of technology-researcher)

●Objective data evaluation

　　In elk test, pile-winding test and track test, the installation of rear anti-roll bar has a positive impact on reducing the degree of vehicle roll, especially in elk test. At the same time, the installation of rear anti-roll bar has certain influence on the transfer rate of vehicle center of gravity, but the effect is not significant. The test data show that the installation of rear anti-roll bar has positive significance in vehicle attitude adjustment, but has no obvious effect on improving handling performance.

　　In the bench test, there are some differences in the change of roll angle, but they are all in a very low range. The bench test data show that the installation of rear anti-roll bar has no significant effect on daily driving.

●Subjective evaluation of testers

　　Testers on the vehicle can feel the somatosensory changes in the vehicle whether the rear anti-roll bar is installed or not during the test. Before the anti-roll bar is installed, the body shakes greatly, and the body feels lifted and thrown down in the steering process, which makes the vehicle feel more stable in driving. After the anti-roll bar is installed, the car body shaking is restrained to some extent, and there is no obvious difference in the lateral shaking of people in the car, which makes the tires slip more easily in the driving of the car.

　　In the process of testing, the tester outside the vehicle can observe the attitude change of the vehicle with naked eyes to a certain extent. Before installing the anti-roll bar, the vehicle shakes greatly, and the compression and rebound stroke of the suspension is longer when steering. After installing the anti-roll bar, there is a significant trend to reduce the body posture sway, which visually feels that the vehicle is more stable.

● Summary

　　　For long-wheelbase vehicles, after installing the rear anti-roll bar, the movement of the rear of the car has indeed changed, especially in the extreme driving state, which can directly perceive the change of the rear following. However, we can also see from the data that there is little improvement in performance, and daily use has no effect on comfort.

　　If you want to operate more directly and restore the function of the rear anti-roll bar, you can choose to install the original spare parts, but the overall improvement is not obvious. It is believed that the change of suspension performance will be more intuitive if it is replaced with the vibration isolator and adjusted in a targeted way.

"The 5G cloud network convergence technology will push China Intelligent Networked Vehicles into a new stage of development and inject new vitality into building a resilient city!" Recently, a high-level closed-door meeting was held in Guangzhou called "5G cloud network convergence helps intelligent networked vehicles develop with high quality". The event invited the major enterprises in the domestic intelligent networked automobile industry, representatives of industry associations and experts from China Telecom Research Institute to discuss the innovative application and future development trend of 5G cloud network convergence technology in the field of smart cars and the construction of resilient cities.

Experts attending the meeting listened to the special report on the integration of 5G cloud network to help the high-quality development of intelligent networked vehicles.

5G Wing-Connected Private Network Scheme Leads Industry Transformation

Different from the traditional vehicle-vehicle networking data completely exposed to the public Internet, the 5G cloud network convergence technology relies on core products such as lightweight 5GC, distributed dUPF, MEC and integrated network management platform, and realizes the access capability of millions of vehicle safety private networks exclusively enjoyed by vehicle enterprises nationwide. In the long run, this technology will provide a safe and efficient operation guarantee for the tens of millions-scale car networking business of a single car company. By providing differentiated QoS guarantee, 5G cloud network convergence technology can accurately meet the diverse needs of different services for network quality. In addition, the scheme also has the characteristics of enterprise security isolation and disaster recovery reliability, which effectively protects enterprise data security and ensures the stable operation of business in complex environment.

Based on the technology of 5G cloud network convergence, China Telecom Research Institute independently developed the 5G wing-connected private network scheme, which has successfully loaded many core services of car networking on the private network, such as vehicle data return, OTA upgrade and car entertainment, and significantly improved the information security and user experience of smart cars. According to Ou Liang, chief expert of China Telecom Research Institute’s cloud network element, the wide-area 5G wing-connected private network solution for intelligent networked vehicles aims at reporting sensitive data of intelligent networked vehicles (such as vehicle identity and driving behavior) and remote control scenarios. By customizing DNN+ exclusive UPF+ remote disaster recovery+weak network enhancement and other technical means, it has created a safe, flexible, reliable and credible exclusive wide-area 5G security private network for automobile enterprises to ensure the full-range transmission of sensitive data within the network. Its innovative highlights include building a multi-level security protection architecture, flexibly expanding to meet the demand of super-large-scale vehicles, combining with edge computing power to realize customized service of cloud network integration, and creating original weak network countermeasures technology to ensure communication stability in extreme network environment.

Experts attending the meeting visited the "2024 Digital Ecology Conference" to listen to relevant introductions.

Cross-industry cooperation to build a resilient city

Experts attending the meeting agreed that China is in a leading position in the world in terms of technical strength and production capacity in the field of intelligent networked vehicles. Tan Hua, a senior expert of China Telecom Research Institute, said that with the blessing and empowerment of the 5G wing-connected private network, the cloud-based control operating system and low-delay graphic transmission core technology can significantly improve the remote control experience of intelligent networked vehicles, solve the problem of asynchronous control operation, and provide an end-to-end remote control scheme for intelligent networked vehicles to quickly get out of trouble and ensure the safety and efficiency of future roads.

Experts attending the meeting pointed out that intelligent networked vehicles have entered a new era of end-to-end data-driven product functions, and data security and OTA update experience are closely related to product sales. 5G technology has been applied in some scenes of intelligent networked vehicles, and it has great application potential in vehicle life cycle. Jiang Zhifeng, vice president of China Telecom Research Institute and general manager of China Telecom Intelligent Network Technology Co., Ltd., said that more than 110,000 vehicles of a new car-making enterprise have been connected to the 5G wing-connected private network, and are moving towards a higher level of on-line goal. "5G cloud network convergence+vehicle networking" shows excellent safety, stability and efficiency when dealing with massive device connections, which helps smart cars to steadily promote the application of assisted driving, achieve a higher level of automatic driving, and improve the level of urban vehicle-road coordination. It can not only bring users safer and more convenient travel services, but also be more conducive to intelligent traffic management in resilient cities.

　　If the Land Rover Defender that cross-country fans care about, because it does not shine or shine in the Chinese car market, so many fans regret it, then the situation may be very miserable compared to the American market, because as early as 1997, the Land Rover Defender was discontinued in the United States. However, to the relief of American consumers, a series of Defender versions will be released next year. For the United States, due to the characteristics of vast land and sparse population, coupled with poor road infrastructure, it seems that the Land Rover Defender with strong off-road capabilities is born for them.

　　People’s Daily Online Entertainment News, comprehensive Hong Kong media reports, actress Wang Zuxian has become a monk in Canada in early June, and the news was relayed to Taiwan by Canadian relatives and friends. However, whether Wang Zuxian has really become a monk still needs to be further verified.

　　Wang Zuxian has talked with Qi Qin about on-again and off-again love for more than a decade, and also intervened in the marriage of wealthy businessperson Lin Jianyue, but the two relationships have ultimately failed to come to fruition. In recent years, Wang Zuxian has faded from the entertainment industry and lived in seclusion in Vancouver, Canada. Qi Qin, an old love, revealed last year that he had not seen Wang Zuxian for four or five years, but the two sides still maintained phone contact. Wang Zuxian believes in Buddhism and rarely talks about the current situation.

　　"She hasn’t been back to Taiwan for a few years. I didn’t know anything about the current situation. I only found out about her ordination after watching TV," said Wang Zuxian, the eldest brother. Is ordination related to feelings? The eldest brother said: "Don’t ask about it." Wang’s father is a basketball master. His mobile phone was not turned on last night.

　　Yang Fan, the director who worked with Wang Zuxian on "A Dream in the Garden", has not contacted Wang Zuxian for a long time, but he said that the outside world should not be too surprised, and it is not necessary to use worldly ideas to measure, which is to respect her.

　　Wang Zuxian had signed a contract with Xu Feng’s company, but later terminated the contract and withdrew from the film industry. Xu Feng’s company executives were quite surprised to hear the rumors of becoming a monk, but they said that they had not heard from her for nearly a year, making it difficult to determine whether the matter of becoming a monk was true or false.

　　Wang Zuxian has collaborated with director Xu Ke on many films of "A Thousand Women’s Ghost". Xu Ke’s wife, Shi Nansheng, said yesterday that she had not heard of Wang Zuxian’s ordination, and had not contacted him since "The Invincible East 3". Recently, so many people have left, and they have to be calm when they hear anything. People should learn to live well. If the ordination is true, it is also her choice and respect it.
