The invention provides a self-learning system and method for the rotating speed and torque direction of a wheel side motor of a hydrogen energy automobile. The method comprises the steps that the hydrogen energy automobile is powered on and started; the GPS multimedia judges whether the vehicle advances forwards or backwards by collecting vehicle position information changes in two adjacent time periods, and sends the advancing direction to the bus; a whole vehicle VCU controller collects gear unit information, accelerator pedal depth information AC and brake pedal depth information PC and sends the information to a bus, the AC and the PC control a motor and send driving torque, and meanwhile the driving mode state is sent to the bus according to the driving state; and the wheel side motor controller assembly outputs the driving torque according to the driving torque sent by the whole vehicle VCU controller, sends out the execution torque and the current rotating speed of the motor at the same time, and executes consistency matching. The vehicle advancing direction is judged according to the change of the relative position of the vehicle, and high reliability and stability are achieved.

    本发明提供了一种氢能汽车轮边电机转速和扭矩方向自学习系统及方法,方法包括:氢能汽车上电启动;GPS多媒体通过采集两个相邻时间段内车辆位置信息变化判定车辆行进方向为前进或者后退,并将行进方向发送至总线上;整车VCU控制器采集档位单元信息,油门踏板深度信息AC,制动踏板深度信息PC,并发送至总线上,并AC和PC对电机进行控制,发送驱动扭矩,同时根据驱动状态发送驱动模式状态至总线上;轮边电机控制器总成根据整车VCU控制器发送的驱动扭矩,进行驱动扭矩输出,同时发送出执行扭矩和电机当前转速,并执行一致性匹配。本发明通过对车辆相对位置的变化判断车辆行进方向,具有很高的可靠性和稳定性。
