摘　　要：为提高纯电动汽车动力驱动系统效率,利用Matlab软件中的Simulink、Stateflow开发了包括加速踏板信号处理模块、驱动模式识别与转换策略和各模式控制策略组成的整车驱动控制策略;其中,在稳态模式下,采用基于车速偏差的增量式PID控制;在瞬态模式下,按照效率最优路径进行控制;在失效模式下,限制电机输出功率。为验证所开发的策略,建立了仿真模型,进行仿真和实车测试。结果表明开发的控制策略是有效的,能提高动力驱动系统效率,延长车辆续驶里程。For improving the efficiency of the power drive system of battery electric vehicle, the Simulink and Stateflow modules of Matlab software are used to develop a driving control strategy for battery electric vehicle, consisting of acceleration pedal signal processing module, driving mode identification and switching strategy and control strategies for each driving mode. With the strategy, incremental PID control based on vehicle speed deviation is adopted in steady mode, the control is exerted following the optimum path for efficiency in transient mode and the output power of motor is limited in failure mode. To verify the strategy, a simulation model for power drive system is built and simulation and real vehicle test are conducted. The results show that the control strategy developed is effective and can enhance the efficiency of power drive system and hence extend the driving range of battery electric vehicle.
