For a car, the driving experience is undoubtedly the core dimension of consideration. Vertical control is the core of solving the pain points of driving, but the traditional suspension in terms of "comfort" - "handling", "off-road performance" - "road driving", often two laws are reversed, and the fish and bear paws cannot be both.
Especially with the development of the automobile industry, users have put forward higher requirements for vehicle power and safety, and it has been difficult to meet the safety needs of vehicles with a single hardware system support in the past, so intelligent fusion control has come into being.
BYD also predicted this trend early and laid out the overall solution of intelligent fusion control, that is, the famous Yunyuan technology, which is also the industry's first new energy exclusive intelligent body control system.
"Intelligent protection and stability", Yunyuan upgrades the safety ability of the whole vehicle
It is understood that the Yunlin is an intelligent body control system developed by BYD Group for 5 years and costing billions of yuan on the full stack, including the Yunlin-C intelligent damping body control system, the Yunnan-A intelligent air body control system, and the Yunnan-P intelligent hydraulic body control system, and more technical product series will be launched in the future.
Specifically, the model equipped with the Yunnan-C is more supportive when cornering, and the chassis texture has been tuned. Especially when passing through speed bumps or dense gravel roads, the damping adjustment of Yunlin-C can make the chassis "soft", reduce the vibration transmission of the road surface, and improve the comfort of driving.
The ICCT intelligent comfort control technology equipped with Yunlin-A will have obvious effects during rapid acceleration or sudden braking, which can effectively suppress the head-up and nodding.
The Denza N7 is equipped with the Yunnan-A, which integrates suspension, braking and drive with ICVC intelligent vector control technology to make the car's attitude more stable and full of handling in corners.
The Yunnan-P intelligent hydraulic body control system integrates the three core technologies of mechanical, hydraulic and electronic control, and is the world's first intelligent hydraulic body control system. With innovative functions of four-wheel linkage and camping adjustment, it can meet the ultimate off-road needs of users.
In general, the cloud technology has carried out all-round intelligent integration in five dimensions, including driving behavior perception, body posture perception, road surface perception, cloud data perception, and system state perception, so that the vehicle can grasp environmental changes in real time and bring users a smart and comfortable experience.
Based on this, the technology has the characteristics of high intelligence, safety protection, stable driving and full coverage.
Especially in terms of safety, Yunyuan technology realizes the dual safety protection of people and vehicles through a number of adjustment functions such as height, damping, and stiffness. It can be said that the cloud technology has brought upgraded safety capabilities to the whole vehicle.
Fill the domestic technology gap and achieve a breakthrough of "0 to 1".
For a long time, domestic manufacturers have been in a disadvantageous position in active suspension and body control technology, and there is still a gap compared with foreign countries.
However, Yunyuan technology has filled the domestic technology gap and achieved a breakthrough from "0 to 1".
More importantly, the birth of Yunyuan technology marks BYD's first mastery of the integrated control technology of three directions and six degrees of freedom of the whole vehicle in the industry, which not only completes the puzzle of vehicle control technology, but also surpasses the advanced level of the industry and realizes the improvement of "from 1 to 2".
In particular, the Yunlin-X will demonstrate a fully active control technology that can realize functions such as "dancing" and "three-wheel driving", representing the highest level of global body control systems.
Not long ago, Porsche's latest Active Suspension Management (PASM) technology development route followed closely and also showed the level of control through "dancing" and other forms, which undoubtedly proves that BYD has once again created a precedent in the industry and led the development of body control technology.
In fact, the automotive industry has been in a research and development gap in the field of vertical control, and the research is relatively fragmented, lacking systematic and comprehensive solutions.
Compared with fuel vehicles of the same size, new energy vehicles have a larger mass, which puts forward new requirements for the higher carrying capacity of the vehicle hardware, and new energy vehicles are more sensitive to wind resistance coefficients, which causes endurance loss due to high wind resistance at high speeds, affecting the user experience.
Therefore, new energy vehicles urgently need a systematic and integrated breakthrough in vertical control.
Yunlin technology also firmly grasps this trend, from the component level, software level, system level to the vehicle level, the quadruple check, to achieve the whole process verification capability of the intelligent body control system.
It also fills the R&D gap in the field of vertical direction control in the automotive industry.
It can be said that the birth of Yunlin technology has a triple significance, which not only fills the gap of domestic automotive technology, but also fills the research and development gap of vertical direction control in the automotive industry, and also leads the development of body control technology in the industry.
