| 摘 要： | 通过对四轮独立驱动电动汽车进行转矩协调控制进行动力学理论分析,表明转矩协调控制可以增强车辆的动力性以及弯道极限行驶性能,提高车辆的操纵性和稳定性。提出采用BP神经网络PID控制方法协调驱动力矩。利用建立的四轮独立驱动电动车7自由度模型进行了阶跃输入、稳态回转和正弦输入仿真。仿真结果表明:提出的转矩协调方法改善了车辆的操纵性和稳定性。

| Abstract: | The analysis of the dynamics of the 4-wheel independent drive electric vehicle indicated that the torque co-ordinated control can enhance the dynamic behavior and the cornering ability limit, and improve the maneuverability and stability of the vehicle. A BP neural network PID control strategy was proposed to control the co-ordinated driving torque. A 7-degrees-of-freedom model was built for the 4-wheel independent drive electric vehicle and its simulations under the step input, the steady-state cornering and the sinuosidal input were performed and the positive results were obtained by the proposed concept. |
