Friends who may not know will have questions. What's the use of dancing in cars? What does this technology mean? What is the actual effect? How is it achieved? With these questions, let's take a look at how awesome BYD's cloud system is!
Before understanding the cloud system, let's take a look at why BYD named this system "Cloud System". The word "chariot" is an uncommon word, which we seldom come into contact with in our daily life today. However, in ancient times, the "chariot" was the car of the ancient emperors in China, symbolizing nobility and luxury, while the "cloud" symbolized the use of intelligent technology to create a lighter and more stable driving experience. On the whole, "Yun Qi" is a symbol of "China's new luxury", which pursues the ultimate in travel and integrates contemporary advanced technology.
In order to greatly improve the comfort, handling, safety, off-road and other dimensions, BYD built this intelligent body control system-Yun Qi Intelligent Body Control System, which took five years and cost several billion yuan. Wang Chuanfu, Chairman and President of BYD Group, said: "The birth of Yun Qi rewrote the history that body control technology relied on foreign countries, filled the domestic technical gap, and achieved a breakthrough from 0 to 1."
According to the official introduction, at present, the product matrix of Yun Qi system mainly includes Yun Qi -C, Yun Qi -A and Yun Qi -P, and these three systems have different characteristics.
Among them, Yunnian -C is an intelligent damping body control system, which adjusts the damping by controlling the electromagnetic valve of the shock absorber, so as to realize the chassis becoming "soft" or "hard". When the vehicle passes through a bumpy road or a sharp bend, accelerates and brakes, it will actively adjust the damping, thus making the vehicle more comfortable and more maneuverable. It is understood that at present, some versions of BYD's Korean, Tang and Tengshi D9 models have been equipped with C hardware, which can be upgraded to C system through OTA later.
Yun Qi -A is an intelligent air control system, which can control the air spring intake and exhaust, stiffness conversion valve, shock absorber solenoid valve and so on. To adjust the height, stiffness and damping, so as to improve the anti-pitching ability of the vehicle, reduce the roll angle speed of the vehicle body, automatically respond to random roads such as pulses, and automatically respond to emergency braking, full throttle acceleration, high-speed cornering and other working conditions.
In addition, the suspension adjustment stroke of Yunnian -A can reach 150 mm, and it also has the functions of speed regulation mode, welcome mode, convenient fetching mode, high security locking, multi-mode personalized setting and intelligent side seat active adjustment. In contrast, Yun Qi -A can make the whole vehicle have the ultimate comfort, support and passability, which is very suitable for luxury high-end models. In the future, Yun Qi -A system will be the first system on Tengshi N7.
Yun Qi -P is an intelligent hydraulic body control system, which integrates three core technologies: mechanical, hydraulic and electronic control, and can realize four-wheel synchronous lifting and single-wheel independent lifting. In addition, Yun Qi -P also supports three-stage stiffness adjustment. In different driving environments such as daily driving, sudden acceleration and deceleration, high-speed cornering and high-intensity off-road, Yun Qi -P makes the vehicle have better comfort, handling, safety and off-road performance by adjusting its stiffness. Therefore, the cloud chariot -P system should be specially built for luxury off-road vehicles, and the upcoming look-up U8 will also be equipped with the cloud chariot -P first.
At the end of the conference, BYD also announced the Yun Qi -X system in the form of eggs. It is understood that Yun Qi -X system is a set of fully active body control technology. It is this system that can make the three wheels of the car still run, make the car dance and even jump in place. In the future, U9 will be equipped with Yun Qi -X system.
These are the strengths of BYD's cloud system, so how is all this achieved? According to the official introduction, Yun Qi system consists of Yun Qi intelligent detection architecture, Yun Qi intelligent computing center, Yun Qi intelligent control technology and key components.
Compared with ordinary suspension, Yun Qi intelligent body control system adds intelligent perception and intelligent decision-making, and constructs a complete system of perception, decision-making and execution. Yun Qi not only broke through the original hardware limitations, but also added "electric wings" to the vehicle in the vertical direction; At the same time, it endows Yun Qi with powerful perception and decision-making ability, active thinking and millisecond response, and realizes all-round intelligent control of the car body.
Among them, the intelligent detection architecture of cloud network starts from five dimensions of people, cars, roads, clouds and systems, and realizes all-round perception with the help of 50+ sensors of the whole vehicle. It can monitor the changes of the car body in three directions and six degrees of freedom, and monitor and identify the road surface characteristics within 5m- 150m in front of the car in advance.
After the cloud-based intelligent detection architecture monitors the information, the cloud-based intelligent computing center will perform high-speed operation and output the optimal control strategy after the operation in real time. It is equivalent to human's "central nervous system" and has multi-core high-performance processing ability.
After the control strategy is output by Yun Qi Intelligent Computing Center, Yun Qi intelligent control technology will realize all the functions of Yun Qi system by controlling the car body, integrating horizontal-vertical-vertical depth control and intelligent driving coordination.
The car detective has something to say.
Prior to this, BYD already had the core technologies of leading industries, such as blade battery, DM-i super hybrid, CTB, EZF, etc. The Yun Qi intelligent body control system released this time is undoubtedly a brand-new technological breakthrough, once again creating an industry precedent and leading the development of body control technology. Most importantly, all of the above are BYD's full-stack self-developed technologies. How can domestic brands that win glory for the Chinese people not be loved?
