The invention discloses a slope sliding prevention control method and system for a pure electric bus, and relates to the technical field of electric bus control, a vehicle control unit controls the torque change rate of a vehicle according to the numerical value of the rotating speed of a motor, and the method comprises the steps that when the vehicle is started on a flat road condition and the vehicle control unit detects that the rotating speed of the motor is within a normal driving range, the vehicle is started; the torque increasing gradient enters a normal driving torque increasing mode; and when the vehicle is started on the abrupt slope and the vehicle control unit detects that the rotating speed of the motor is within the set slope sliding range, the torque increasing gradient enters an anti-slope-sliding rapid torque increasing mode. The backward sliding distance is reduced by increasing the torque change rate on the slope, the motor rotating speed vector value serves as a judgment condition for judging whether the slope exists or not, the whole vehicle controller controls the torque change rate of the whole vehicle according to the specific value of the motor rotating speed, and the slope sliding prevention control effect is improved.
本发明公开了一种纯电动客车防溜坡控制方法及系统,涉及电动客车控制技术领域,整车控制器根据电机转速的数值控制整车的扭矩变化率,包括:车辆在平坦路况起步,且整车控制器检测到电机转速在正常行车范围内时,加扭梯度进入正常行车加扭模式;车辆在陡坡起步,且整车控制器检测到电机转速在设定溜坡范围内时,加扭梯度进入防溜坡快速加扭模式。本发明通过在坡度上加大扭矩变化率来降低后溜距离,通过电机转速向量数值作为坡度有无的一种判断条件,整车控制器根据电机转速的具体数值控制整车的扭矩变化率,提高防溜坡的控制效果。
