The invention relates to the technical field of electric vehicle control performance optimization, and provides a steering auxiliary torque control method, a vehicle controller and an electric vehicle. The method comprises the following steps that vehicle driving state data and driving operation data are obtained in real time, and the driving operation data comprise operation change data of a steering wheel, a brake pedal and an accelerator pedal; determining the current working condition of the vehicle according to the vehicle driving state data and the driving operation data; according to the current working condition of the vehicle, a corresponding torque request is generated and sent to an electric drive control system; wherein if the current working condition is the turning working condition and no torque request is received, a turning torque request is generated and sent to the electric drive control system. When it is detected that the vehicle is in the turning working condition, the braking torque request is generated, meanwhile, instantaneous response output of the motor torque is controlled, and turning stability is guaranteed.

    本发明涉及电动汽车操控性能优化技术领域,提供了一种转向辅助扭矩控制方法、车辆控制器及电动汽车。所述方法包括以下步骤:实时获取车辆行驶状态数据和驾驶操作数据,所述驾驶操作数据包括方向盘、制动踏板和油门踏板的操作变化数据;根据所述车辆行驶状态数据和驾驶操作数据,确定所述车辆当前所处工况;根据所述车辆当前所处工况,生成相应的扭矩请求,发送至电驱动控制系统;其中,若当前所处工况为转弯工况,且未接收到任何扭矩请求,则生成转弯扭矩请求,发送至电驱动控制系统。本发明能够在检测到车辆处于转弯工况时,生成制动扭矩请求,同时控制电机扭矩的瞬时响应输出,保证过弯的稳定性。
