Let the driving experience be more advanced. Yunnian Intelligent Body Control System

  Nowadays, the automobile has entered the era of diversified development. A car product that is loved by consumers can have a lot of labels, such as high value, scientific and technological intelligence, humanization, multi-purpose and so on. These labels can also be changed and sublimated with the changes of the times and the development of automobiles, but I think that as a means of transportation, people’s pursuit of driving comfort will never change.

  When it comes to the driving comfort of cars, we have to mention the "chassis suspension" system, one of the three major parts that both oil cars and trams will have. In the chassis suspension system, the suspension system, as the only structure that connects the upper and lower car bodies, plays a vital role in its design and adjustment.

  In fact, among the global automobile brands, many well-known brands have made research and innovation on automobile suspension, such as the magic body of Mercedes-Benz, KDSS of Toyota and HBMC of Nissan. Their birth has greatly improved the driving stability and comfort of automobiles. So is there a brand or a technology in China that can reach or even surpass them? Then I think the answer is yes. It is the industry’s first new energy exclusive intelligent body control system-Yunqi.

  What is a cloud chariot?

  Everyone must remember the "dancing" U9 sports car at BYD Yunqi conference. It appeared in that way, which not only won the attention of the public, but also proved the strength of Yunqi intelligent body control system to the global automobile market.

  Yunqi is an intelligent car body control system developed by BYD Group for five years and costing billions of yuan. It includes Yunqi -C intelligent damping car body control system, Yunqi -A intelligent air car body control system and Yunqi -P intelligent hydraulic car body control system, covering the needs of different driving scenes such as home, sports, administration, off-road and entertainment. This time, we also experience the actual use feeling brought by different systems through the experience under various working conditions.

  Yunnian -C Intelligent Body Damping Control System

  If the intelligent body control system of Yunqi is classified, then Yunqi -C should be considered as a more popular and popular one. It is mounted on BYD Tang, BYD Han and BYD Song L just launched.

  The damping continuous variable adjustment function of Yunqi -C can solve the uncomfortable feeling of passengers in the car when the car is driving at high speed on a rough road or slightly bumping, and increase the comfort of the car. In the rough road, the system will increase the low-frequency damping through the cloud algorithm to stabilize the body posture when the vehicle is thrown up and down. To put it bluntly, it can avoid shaking like a boat and reduce the dizziness of passengers.

  When passing through the washboard road or the gravel road, the system will automatically adjust the damping of the shock absorber to be low, and at this time, the compression and stretching speed of the vehicle’s shock absorber will also be improved, so that it can respond and resolve the continuous high-frequency impact quickly. Commuting in the city will make the ride more comfortable.

  In this test drive, I also experienced the model Tengshi N8 equipped with Yunqi C intelligent body damping control system for a long time. Through the driving experience of high-speed, national roads and roads, the overall comfort performance brought to me is better than that of the same class without body damping control system. In addition to coping with the impact caused by falling and bumps on the vehicle, you can also feel the full lateral support of the vehicle when going up and down the ramp or turning quickly. The attitude of the vehicle and the lateral stability of passengers in the vehicle are very good, and with the comfortable parking function, this system is completely ok for daily use.

  Yunnian -A Intelligent Air Body Control System

  If Yunqi -C intelligent body damping control system only appears as a popularizer, then Yunqi -A intelligent air body control system can be regarded as a more advanced version, or a luxury benchmark for vehicle dynamic control. It realizes the dynamic adjustment of the body control through the precise sensing technology of Yunqi, the quick decision of Yunqi Intelligent Computing Center, the output of precise control strategy, and the control of air spring intake and exhaust, stiffness conversion valve, shock absorber solenoid valve, etc., so that the whole vehicle has the ultimate comfort, stability, support and passability. That is, with the addition of air spring, the vehicle equipped with Yunqi -A intelligent air body control system has become a necessary condition for you to have a higher-level and more interesting driving experience.

  Yunqi -A intelligent air body control system can be adapted according to different vehicle types, and the suspension adjustment stroke is as high as 150 mm. Vehicles equipped with Yunqi -A system can provide users with multiple modes including driving mode linkage suspension, welcome mode, convenient pick-up mode and high safety locking.

  The Yunqi -A intelligent air body control system also provides an electrically controlled shock absorber, which can realize stepless adaptive adjustment of damping. In addition to independently adjusting the appropriate body damping in different road conditions to ensure the driving stability of the vehicle, it can also alleviate the situation of braking and nodding when the vehicle starts, thus avoiding the dizziness caused by riding an electric vehicle. The vehicle roll angle speed can also be reduced by 23%. Simply speaking, when cornering at high speed, the vehicle side support force is more sufficient.

  This test drive is equipped with Yunnian -A intelligent air body control system. When passing through speed bumps and potholes, the overall suspension will give me a more resilient feeling, and the wheels will not bounce unnecessarily. When encountering potholes, bumps are basically not transmitted to the car, and when passing through, you can obviously feel that the integrity of the vehicle chassis and shock absorber is very good.

  On the mountain road with many bends, the vehicle’s roll is not big, which is related to shock absorption and steering in cooperation with the driving mode. In the sports mode, Tengshi N7 has good sports properties, and the directivity of the bend is good, and it is also silky when it turns quickly. The intelligent seat flanking function pioneered by Yunqi -A intelligent air body control system can quickly control the intelligent flanking seat according to the body posture change and steering signal. If the center of gravity of the vehicle turns to the right and it is cheaper to the left, the body will lean to the left, and then the intelligent seat flanking on the left will exert an opposite force on the body and actively support the side. This function can be used not only in sports driving, but also in low-speed off-road.

  Yunnian -P Intelligent Hydraulic Body Control System

  If Yunqi -C and Yunqi -A put more comfortable driving on the road, then Yunqi -P intelligent hydraulic body control system not only takes into account the road comfort, but also strengthens the off-road performance and balances the road and off-road working conditions.

  Through the precise sensing technology of Yunqi, and the quick decision-making of Yunqi Intelligent Computing Center, the control strategy is output, and the oil intake of shock absorber, damping regulating valve and stiffness regulating valve are controlled to realize the dynamic adjustment of body control. Yunqi -P is the world’s first intelligent hydraulic body control system, which integrates three core technologies: mechanical, hydraulic and electronic control. At present, it is mounted on the high-heat and equation Leopard 5 model.

  Cross-axle working condition is one of the common working conditions in cross-country. If you want to pass smoothly, you must not only have strong locking function, but also have more tires to grip the ground, which is also an indispensable and important condition for getting out of trouble. Yunnian -P intelligent hydraulic body control system provides the function of "four-wheel linkage". When the vehicle is in a semi-unbalanced state with single wheel and diagonal wheel suspended, the four-wheel linkage function can transport oil for the suspended wheel shock absorber, lengthen the suspension stroke, improve the wheel contact with the ground and the sense of vehicle balance, and ensure the effective output of four-wheel power. The four-wheel linkage function of Yunqi -P can make the maximum wheel difference of the vehicle reach 620mm, and the tracking index RTI value of the whole vehicle can reach above 600 according to official data, which is the upstream level in non-modified mass production off-road vehicles.

  Camping is a hot outdoor activity nowadays. If the parking place is complex and uneven, and the vehicle tilts, it will affect the need for rest and entertainment in the car. At this time, the user can turn on the camping leveling mode. At this time, the vehicle will calculate the inclination angle through the attitude control module and adjust the body to a horizontal position several times. The adjustment range is about 100 mm. If it exceeds this adjustment range, the system can only try to ensure the balance of the car body.

  Do you usually encounter such a situation when driving? When a tall SUV body enters the basement, it is often blocked by a 2m height limit pole, which makes it impossible to enter the basement for parking, or when you encounter a lower bridge opening on the off-road road road, it will affect the whole trip. Aiming at this kind of working condition and user’s pain points, Yunqi -P intelligent hydraulic body control system provides "ultra-low mode". As long as you step on the brake pedal, in the mode with the lowest body height, the system will automatically enter the ultra-low mode by continuously pressing the height adjustment button for 7 seconds. At this time, the system will reduce the body height to 1.9 meters, and it can smoothly pass through the road section or closed space with height restrictions.

  The prospective cloud-chariot preview system in the future

  In the venue of this experience, we also saw a lookout U8 equipped with a cloud-based preview system. Yunqi preview system can respond quickly by identifying structured road surface and obstacles in front through lidar and binocular camera on the roof, and adjusting damping in linkage. It can output the road surface features and elevation curves within the range of 5-150m in front of the vehicle, and the recognition accuracy is 3 mm, and the recognition accuracy within 15m is over 99%. Of course, the technology is currently in the debugging stage, or it will be pushed and upgraded to users through OTA later. At present, only BYD is involved in this technology.

  Now the staff also demonstrated the practical application of the cloud-and-chariot preview system to us. After U8 recognizes the obstacle (log) at the center of gravity in the process of moving forward, the car body will slowly lift adaptively to increase the chassis passability, and the height of the car body will gradually return to the original height after passing.

Let the driving experience be more advanced. Yunnian Intelligent Body Control System

  Full text summary:This time, we fully experienced BYD’s Yunqi -A, Yunqi -C and Yunqi -P intelligent body control technologies applied in different fields and models. Personally, I think this technology is at the leading level in China in terms of technology, market level and user level. After all, there are not many independent car companies that are vigorously involved in vehicle chassis shock absorption control, and BYD is at the forefront of the market.

  From the actual driving experience of these three sets of cloud technology, it is indeed better than the driving texture of the same class models, and the sports performance is also better. The most important thing is that BYD will bring down the altar such technologies as continuously variable damping technology and air spring technology, which were originally only carried in higher-priced models, so that more domestic users can experience high-level driving performance at lower prices. We should praise BYD for this.

  Hefei stalls are divided into "forbidden areas" and "diversion areas"

  The setting area of Hefei stalls is divided into "forbidden area" and "diversion area". Among them, the "forbidden area" refers to the main roads, window units, squares, bridges (including footbridges), underground passages, the periphery of office areas, the entrance and exit of the campus within 100 meters, and other areas where stalls are not allowed to be set up as stipulated by laws and regulations. In addition to the forbidden areas, the areas outside the forbidden areas shall be demarcated by the district governments and development zone management committees and announced to the public without affecting the lives of citizens and traffic, and shall be standardized and managed according to the standards.

  There are 37 stalls in the "grooming area" to provide convenience for the public. In addition to 37 temporarily defined stalls, there are some seasonal or temporary convenience stalls in Hefei, mainly including temporary watermelon sales outlets, breakfast carts, kiosks and so on.

  Xiamen has been trying out the "booth" since 2019.

  Since June last year, the trial of "booth" has been carried out, and 50 "booth" of various types have been built in Xiamen, providing 1150 booths. In addition to the autonomy of business households, urban management and law enforcement departments also cooperate with relevant responsible units to do a good job in food safety and environmental sanitation management at these "stalls".

  Xiamen Urban Management and Law Enforcement Bureau said that it will further communicate and coordinate with relevant departments, make full use of idle venues, roads with few cars, beaches, etc., and establish flea markets, gourmet streets, fruit markets, etc. in a time-limited manner to bring more mobile vendors into orderly management.

  For the first time at the provincial level in Shaanxi Province, the "four permits" on the occupation of roads were put forward.

  On May 27th, Shaanxi Province issued a notice, proposing that "street shops in urban areas should be allowed to operate without affecting pedestrian access and ensuring safety, large shopping malls should be allowed to occupy the road for promotion, temporary stalls should be opened in residential areas, and mobile vendors should be allowed to occupy the road for operation at a certain time and area". This is the first time at the provincial level in Shaanxi Province that the "four permits" on the occupation of roads have been put forward.

  At the same time, Xi ‘an plans to set up 100 vegetable morning markets, 100 night market barbecue centralized management areas and 100 temporary food stall sites this year.

  At the same time, netizens have also given advice to the economic development of the stalls: "The bottom line of maintaining hygiene, exclusive areas and food safety should also be adhered to." "It is allowed to set up stalls, but it can’t be arbitrarily placed, and a new harmonious and win-win economic order will be established." "Don’t overdo it, don’t be across the board."

  Expert: Letting go of the stall economy does not mean letting go of responsibility.

  During the development of stall economy, it is inevitable to cause some urban management problems, such as sanitation and pollution, traffic congestion, noise disturbing people, insecure commodity quality and safety, social security and tax evasion.

  The essay suggests taking this opportunity to solve the long-standing problem of standardizing stall economy in one fell swoop. The first is to register and manage the practitioners in the stall economy. The second is to limit the space and time of operation to avoid affecting traffic. The third is to strengthen the control of health pollution and establish an emergency management system for epidemic prevention. The fourth is to set up a service quality supervision mechanism to protect consumers’ rights and interests. The fifth is to improve management efficiency with the help of Internet thinking, such as online application, registration and tax filing.

  Zhang Zhixin said that letting go of the stall economy does not mean letting go of the responsibility, nor does it mean giving up the law. In terms of food safety, environmental pollution and other aspects related to the vital interests of the people, urban law enforcement departments must investigate reports, investigate violations and enforce the law strictly. But at the same time, we should avoid overcorrection and one size fits all. (Zhongxin Jingwei APP)
