摘要：
In order to reduce the degree of speed reduction in the stability control and the longitudinal force utilization of the tires, the longitudinal force of each wheel is assigned by the secondary programming method based on the distributed electric vehicle platform. The yaw moment distribution based on the wheel motor output driving/braking force is preferred. When the required yaw moment exceeds the maximum torque of the wheel motors, the hydraulic brake system is activated to compensate. The results of Double Lane Change (DLC) simulation test demonstrate that, compared with the differential braking control system, the error between distributed electric vehicle stability control system and the ideal vehicle speed is kept within 1 km/h, the vehicle speed decreases by 82.25%, and the average tire force utilization rate is reduced by 9.71%. The stability control system can improve the stability and the safety of the driving vehicle. Under the acceleration/deceleration conditions, it provides good robustness. © 2018, Editorial Board of Jilin University. All right reserved.
