The invention provides an electric vehicle torque safety monitoring system and method. The system comprises peripheral hardware, a vehicle control unit, a motor controller and a motor. The peripheral hardware is used for acquiring a torque control signal of a user; the vehicle control unit analyzes the torque control signal into a torque demand, judges whether the torque demand is reasonable or not, and outputs the reasonable torque demand; whether torque following is normal or not is judged according to the torque feedback signal and the torque requirement; the motor controller is used for analyzing the torque demand into a torque execution signal, judging whether the torque execution signal is reasonable or not, and driving a motor to execute torque change according to the reasonable torque execution signal; a torque feedback signal is also output. According to the method, vehicle torque safety monitoring is achieved on the whole vehicle controller strategy layer, the vehicle cost is reduced, the torque control accuracy and robustness of the electric vehicle are improved, and the driving safety is improved.

    本发明提供一种电动汽车扭矩安全监控系统及方法,该系统包括:外围硬件、整车控制器、电机控制器和电机;外围硬件用于获取用户的扭矩控制信号;整车控制器将扭矩控制信号解析为扭矩需求、判断扭矩需求是否合理,并输出合理的扭矩需求;还根据扭矩反馈信号与扭矩需求判断扭矩跟随是否正常;电机控制器用于将所述扭矩需求解析为扭矩执行信号、并判断扭矩执行信号是否合理,根据合理的扭矩执行信号驱动电机执行扭矩变化;还输出扭矩反馈信号。本发明在整车控制器策略层上实现了车辆扭矩安全监测,降低了车辆成本,提高了电动汽车的扭矩控制精确性与鲁棒性,提升了行车安全性。
