The invention discloses a method and a system for an anti-slip-slope torque control system of an electric vehicle. The method for anti-slip-slope torque control of the electric vehicle comprises the following steps: S11, a vehicle control unit receives a vehicle rotating speed signal sent by a motor controller and a gear signal, collected in real time, of the vehicle in real time; S12, the vehiclecontrol unit judges whether the current vehicle enters an anti-slip-slope mode or not according to the received vehicle rotating speed signal and the collected gear signal of the vehicle, and if thereceived vehicle rotating speed signal and the collected gear signal of the vehicle meet the anti-slip-slope condition, and the vehicle control unit requests a motor controller to enter speed mode control; and S13, when the output torque of the vehicle control unit is larger than the output torque of the motor controller, the slip slope prevention mode is quitted, and the vehicle control unit requests the motor controller to enter torque mode control. Other controllers and hardware do not need to be added, so the weight and arrangement work of the vehicle are reduced; and the anti-slip-slope function can be directly added in the vehicle control unit to realize the anti-slip-slope function.
本发明公开了一种电动汽车防溜坡扭矩控制方法及系统。本发明涉及的一种电动汽车防溜坡扭矩控制方法,包括步骤:S11.整车控制实时接收电机控制器发送的车辆转速信号及实时采集的车辆的档位信号;S12.整车控制根据接收到的车辆转速信号以及采集到的车辆的档位信号判断当前车辆是否进入防溜坡模式,若接收到的车辆转速信号及车辆的档位信号满足进入防溜坡的条件,则整车控制请求电机控制器进入速度模式控制;S13.当整车控制器输出扭矩大于电机控制器输出扭矩,则退出防溜坡模式,并且整车控制请求电机控制器进入扭矩模式控制。本发明无需增加其他控制器和硬件,减少整车重量和布置工作;可直接在整车控制器中增加防溜坡功能即可实现。
