摘　　要：对四轮独立驱动电动汽车转向运行学进行分析,建立七自由度转向动力学模型。通过七自由度转向动力学模型,提出了基于滑膜理论的转速转矩协调控制策略。根据滑膜控制器和转矩分配模块计算出车辆在稳定运行状态下四个车轮输出的转矩,再根据测量车辆在稳定状态下转向时的侧偏角分别计算出四个车轮的转速。在单线工况下的仿真结果表明论文设计的控制策略可行性和合理性。The seven degree of freedom steering dynamics model was established by the analyzed of the steering operation of four wheel independent drive electric vehicle. The speed and torque coordinated control strategy is proposed based on the theory of synovial membrane based on the seven degree of freedom steering dynamics model. Four wheel torque output was calculated according to the vehicle stability controller and synovial torque distribution module, Four steering wheel speed was calculated by the sideslip angle also. The simulation results show that the control strategy is feasible and reasonable.
