Yangwang Auto releases new energy hardcore SUV: Yunnan-P intelligent hydraulic body control system unveiled

According to news on June 7, Yangwang Automobile recently held a technical communication meeting on the Yunnan-P intelligent hydraulic body control system, introducing in detail its first new energy hardcore SUV - Yangwang U8. It is equipped with the Yunnan-P intelligent hydraulic body control system. By integrating software and hardware technology innovations such as perception, decision-making, control, and interaction, the system systematically considers the vertical control issues of new energy vehicles, providing excellent performance for the driving experience in urban and off-road scenarios.

According to the editor’s understanding, the Yunnan-P system integrates three technologies: mechanical, hydraulic and electric. It realizes dynamic adjustment of body control by controlling the oil inlet volume of the shock absorber, damping adjustment valve and stiffness adjustment valve. . The U8 is equipped with 17 1 functional modes, including comfort, economy, sports driving modes, as well as special working mode modes such as multiple terrain modes, in-situ steering and driving with a trailer, and also introduces innovative modes such as "curvature engine".

Using the road surface preview system to identify urban road characteristics, the Yunnan-P system can accurately adjust suspension damping to improve the vehicle's ride comfort. Through body posture perception and driving behavior perception, the system dynamically monitors the vehicle status and outputs the optimal control strategy, suppressing the head-up phenomenon during rapid acceleration and nodding during sudden braking, and improves driving stability. In addition, the vertical-lateral cooperative control of the body enhances the stiffness of the body in scenarios such as turning and changing lanes, improves the damping effect, reduces the vertical displacement and roll gradient of the body, and effectively controls the body attitude. The four-wheel height is independently adjusted to balance the load to maintain a balanced body posture; the suspension height is adaptively adjusted to adjust the height according to changes in vehicle speed to improve driving stability and passing safety; the height of the rear axle is automatically lowered to facilitate loading and unloading of luggage or entering and exiting the basement. .

In off-road scenarios, the front and rear suspension adjustment travel of the U8 can be up to 150 mm, and the vehicle height can be raised by 80 mm or lowered by 40 mm in manual mode. After the suspension of the luxury version is raised, the approach angle reaches

to ensure that the vehicle has good passability in different scenarios. It is necessary to control the departure angle of the body to 35.4 degrees and the longitudinal passing angle to be within 25.5 degrees and maintain 36.5 degree tilt angle. Thanks to the 150mm suspension adjustment stroke, the luxury version model can handle a maximum wading depth of 1 meter when there is no need for wading; while the off-road player version model can handle a maximum wading depth of 1 meter when equipped with a wading hose. Up to 1.4 meters.

In addition, the Yunnan-P system uses four-wheel linkage technology to provide shock absorber oil delivery to the wheels that are about to be suspended, lengthen the suspension stroke, and improve the wheel's ground contact and vehicle balance. Through the "one-button leveling" mode, the vehicle can independently control the height of the four wheels when it is stationary, and always keep the body perpendicular to the direction of gravity. In emergency situations such as flying over sand ridges, falling down slopes, etc., the Yunnan-P system can emergency trigger the third-level stiffness to reduce the impact load by 50% to ensure the safety of vehicles and personnel.

It has been previously reported that the Yangwang U8, the first new energy hardcore SUV launched by the Yangwang brand, started pre-sales at the Shanghai Auto Show in April, with a pre-sale price of 1.098 million yuan.
