轮毂电动机驱动电动汽车DYC+AFS协调控制策略
Coordinated control strategy of DYC and AFS for in-wheel motor drive electric vehicle
摘要
Abstract
The coordinated control strategy of active front-wheel steering(AFS)and direct yaw moment control(DYC)was proposed to enhance the lateral stability of in-wheel motor distributed drive vehicles.Based on the two-degree-of-freedom theoretical model,the AFS system was designed using sliding mode control to correct the front wheel steering angle,while the DYC controller was developed based on model predictive control(MPC)with the objective of maintaining vehicle stability and minimizing tire load through optimal torque distribution across all four wheels.The coordination between AFS and DYC controllers was achieved by the phase-plane analysis.The results show that under the double lane-change maneuver,the maximum error between vehicle yaw rate and desired value is only 12.8%,and the peak sideslip angles are reduced by 3.80%and 9.40%compared to those of AFS-only and DYC-only control,respectively.Under the sinusoidal lag maneuver,the maximum yaw rate error is 15.1%,and the peak sideslip angles are reduced by 61.40%and 64.01%compared to those of AFS-only and DYC-only control,respectively.The proposed strategy significantly improves the vehicle handling stability and exerts less intervention on longitudinal speed with better speed maintenance and improved driving comfort.关键词
