摘　　要：研究了一种实际双电机耦合驱动纯电动客车的综合控制。根据双电机行星耦合驱动系统的结构与工作原理,将系统分为低速单电机模式与高速双电机模式,制定了对应不同工作模式及模式切换过程的控制策略,设计了控制器系统及控制流程,并进行了仿真验证。仿真结果表明,该双电机耦合驱动系统控制器能有效实现对双电机动力的控制,在满足驾驶员需求转矩的前提下,提高了系统的综合效率。A study of control of a practical dual-motor coupling drive system on electric vehicles（EV） was conducted.The dual-motor planetary coupling drive systems were divided into the low-speed single motor mode and the high-speed dual-motor mode according to their structures and working principles.Then,the control strategies for different modes and the mode switching process were made,and the controller and control processes were designed.And finally,they were verified by simulation.The test resucts showed that this controller for the practical dual-motor coupling drive system can ensure the distribution of dual-motor power,and enhance the system efficiency under the condition of satisfying driver＇ s requirement on torque.
