For a long time, Mercedes-Benz technology has been the benchmark in the field of body control and chassis control.
However, on the evening of April 10, BYD broke the benchmark position of Mercedes-Benz and people's conventional cognition.
On this day, BYD Auto released the technical concept of Yun Qi. This concept, through a series of active body control technologies, fills the technical gap of domestic manufacturers, and is also expected to break a series of rules formulated by overseas luxury brands in the early stage.
First of all, what is a "cloud chariot"?
"Cloud" is soft and light, symbolizing lightness and stability.
"Chariot" was the top transportation tool used by ancient emperors.
BYD Auto named a brand-new active body control technology "cloud chariot", which means that even if the road is rugged, the vehicle can be as stable as Mount Tai, just like a cloud chariot.
Therefore, the key of cloud technology is to bring more top-level safety, driving control and comfortable experience through decoupling control and multi-dimensional perception, intelligent control and stable execution. At the same time, in terms of cloud technology, it covers four sets of intelligent body control systems: cloud -C, cloud -A, cloud -P and Cloud-X.
Among them, Yun Qi -A is an intelligent air control system.
This system is based on damping control, height control and intelligent sensing technology, which can bring more comfortable and practical air suspension experience.
In addition, the core advantage of Yun Qi -A body control system is that the matching degree will be more mature. BYD Yun Qi-The body control system is independently developed by BYD from hardware to software. Compared with air suspension products from third-party parts suppliers, Yun Qi -A has advantages in vehicle integration and matching.
Yun Qi -C is an intelligent damping body control system.
Based on damping control technology and intelligent sensing technology, the system has millisecond damping adjustment ability. By adjusting the damping of the shock absorber, it can not only support and shock absorption, but also support the functions of anti-vertigo and pitch control of the electric vehicle, which brings more comprehensive handling ability to the vehicle.
Yun Qi -P is an intelligent hydraulic body control system.
The system will be installed on the new energy off-road vehicle U8 for the first time. Besides damping control, height control and intelligent perception, the system also has four-wheel linkage technology. Simply put, this system can comprehensively optimize the chassis according to the characteristics of off-road vehicles.
For example, when camping on an unpaved road, the vehicle can independently adjust the height of each suspension position to make the vehicle more flat. When off-road, the maximum single-wheel height difference supported by Yun Qi -P can reach 620mm, which greatly improves the passing capacity of vehicles.
As for the last cloud chariot -X, the flagship system of cloud chariot technology sequence.
The biggest feature of this system is to realize the full active control of the chassis. At the press conference, look-up U9 equipped with Yun Qi -P demonstrated the power of Yun Qi -X through dancing and bouncing vehicles.
When applied to actual driving, this technology can even achieve zero roll and zero pitch body posture, further improving the ride comfort of the vehicle in the process of automatic driving or intense driving. And applied to super-running vehicles, such a body control system also greatly improves the steering limit of the vehicle.
What technical advantages did BYD show behind Yun Qi?
BYD's cloud technology is equivalent to bringing a set of intelligent strategies to the body control system.
From perception to control, the whole body can be automatically adjusted, thus bringing the best driving posture and ensuring driving maneuverability and riding comfort. From the principle of understanding, this technology is actually not complicated.
However, if we want to refine every link, this set of technology is quite complicated.
First, let's start with Xiaoyun's perception system.
The sensing technology of Yun Qi intelligent body control system includes five dimensions.
These five dimensions are cloud data perception, vehicle attitude perception, real-time road condition perception, system state perception and driving behavior perception.
These senses are provided by big data, vehicle attitude instrument, camera, radar and other components. At present, there are 57 sensing units, which can monitor all kinds of information of vehicles in real time. The number of sensor units alone exceeds 57, and we can also imagine the R&D investment behind Yun Qi.
Besides the need for more accurate perception, Yun Qi's key lies in "calculation" and "execution".
What we know is that Xiao Yun's main control logic is to actively control the suspension from three spatial dimensions.
In the control system, the system needs a smart "brain" to make judgments and decisions.
To this end, BYD has also developed a powerful computing center for Yun Qi.
For example, if a vehicle has an accident and a single wheel leaves the body, the cloud system can quickly sense the state of the vehicle, adjust the suspension height of the wheel position, and keep the vehicle running.
In the later stage, Yun Qi can be deeply integrated with ADAS driver assistance system, thus providing vehicles with more innovative functions and smarter and more comfortable travel experience.
What impact will the cloud chariot bring to the market?
In fact, after overseas luxury brands developed "magic carpet suspension", even for a long time, the research direction of body control was flat. In the research of vertical direction, it is basically on the hardware level of damping and shock absorber, and there are few systematic eyeballs.
This time, BYD Yun Qi broke the original hardware limitation.
In the aspect of vertical control ability, intelligent wings are added to the vehicle, thus giving it strong self-perception and decision-making ability. This kind of ability blessing will be a qualitative leap for the driving experience of vehicles.
With the release of cloud technology, we can almost be sure that the car body control technology will enter a new era in the future car market.
At the same time, for BYD itself, cloud technology is also an important part of BYD's technology upward strategy.
In the early stage, BYD brought core drive technologies such as DM-i super hybrid, blade battery and easy Sifang motor control technology ... These technologies successfully helped BYD achieve breakthroughs again and again and won the results of brand promotion.
But BYD's chassis has always been the weak link.
The smooth release of cloud technology also marks that BYD has completed the platformization of control technology in the industry, which has brought a leap in core quality from three dimensions.
In the future, BYD will also take the lead in carrying different components of the cloud system on flagship models such as Dynasty, Ocean, Tengshi and Want Want.
These new cars equipped with cloud technology also mark that China's new energy vehicles have officially entered a new era, and BYD is also expected to define new standards for new energy luxury cars.
Write at the end:
In 2022, BYD achieved sales of more than 6.5438+0.8 million vehicles, becoming the "boss" in the field of new energy vehicles in the world.
In 2023, BYD set a heroic goal of "sprinting 3.6 million". Such a goal is quite difficult for any car company. But we believe that with the emergence of cloud technology and more new technologies, BYD can turn "impossible" into "possible".
At the same time, in addition to sales, BYD's brand value is gradually improving with the emergence of these new technologies. We believe that in the near future, BYD will occupy a place in the global mainstream luxury car market.
