The acceleration slip regulation control for two-wheel independent driving electric vehicle based on dynamic torque distribution

In this paper, the research object is rear wheel independent drive electric vehicle. For tackling the problem of the occurrence of undesired yaw moment and yaw angular velocity when the driving force control system of independent driving electric vehicle enters the working mode of ASR, a novel control acceleration slip regulation (ASR) strategy based on dynamic torque distribution is proposed for this two-wheel independent driving electric vehicle. The novel controller is consists of two parts, the first part is the single wheel ASR based on fuzzy control, the second part is the dynamic torque distribution controller. In order to evaluate the performance of the algorithm, the Carsim full-vehicle model is used to establish a co-simulation platform with MATLAB/SIMULINK software, and the control strategy is simulated on the platform. The simulation shows that the acceleration slip regulation based on dynamic torque distribution improves the lateral stability and dynamic tracking capability compared with the conventional ASR.
