The invention relates to a pure electric vehicle driving motor control method based on driver acceleration intention recognition. The method mainly comprises the following steps that (A) a vehicle control unit distributes reference output torque and dynamic compensation torque to a motor, and the total output torque of a driving motor is obtained by adding the reference output torque and the dynamic compensation torque; (B) the vehicle control unit collects real-time signals of an accelerator pedal position sensor and real-time signals of the motor rotating speed and controls a driving motor to output corresponding reference torque; (C) the vehicle control unit collects a real-time vehicle speed signal and an accelerator pedal opening change rate signal, recognizes the acceleration intention of the driver, and gives different dynamic compensation torques to the driving motor according to the intensity of the acceleration intention; and (D) before the vehicle control unit applies the compensation torque to the motor, whether the received acceleration instruction is misoperation of a driver or not is judged firstly, and if not, the dynamic compensation torque is given to the motor. According to the method, the economical efficiency is effectively improved while the instantaneous acceleration performance of the electric vehicle is ensured.
本发明涉及基于驾驶员加速意图识别的纯电动汽车驱动电机控制方法。该方法主要有以下几个步骤:(A)整车控制器分别分配给电机基准输出转矩和动态补偿转矩,驱动电机总的输出转矩由二者相加得到。(B)整车控制器采集加速踏板位置传感器实时信号和电机转速实时信号,控制驱动电机输出相应的基准转矩。(C)整车控制器采集实时车速信号与加速踏板开度变化率信号,识别驾驶员的加速意图,根据加速意图的强弱给予驱动电机不同的动态补偿转矩。(D)整车控制器在对电机施加补偿转矩之前,先判断所接收的加速指令是否为驾驶员误操作,若非误操作,则给予电机动态补偿转矩。本发明使电动汽车在保证瞬时加速性能的同时,经济性得到有效改善。
