The invention relates to an anti-slope-sliding control system and method for an electric vehicle, computer equipment and a storage medium. The system comprises a motor controller and a vehicle controlunit. The motor controller is used for judging whether an electric vehicle is in a slope sliding state or not according to the driving state of the electric vehicle, loading a non-creeping torque tocarry out anti-slope-sliding control on the electric vehicle when the electric vehicle is in a slope sliding state, and unloading the non-crawling torque and sending an instruction that the motor exits from the anti-slope-slipping control to the vehicle control unit when the electric vehicle meets a preset creeping condition. The vehicle control unit is used for determining the creeping torque ofthe vehicle control unit according to the driving state when receiving the instruction that the motor quits the anti-slope-slipping control, and carrying out anti-slope-slipping control on the electric vehicle according to the creeping torque. By the adoption of the system, stalling or overshoot of the motor can be avoided, and anti-slope-slipping control can be conducted according to the intention of a driver.

    本申请涉及一种电动汽车防溜坡控制系统、方法、计算机设备和存储介质。所述系统包括:电机控制器和整车控制器;电机控制器,用于根据电动汽车的行驶状态判断电动汽车是否处于溜坡状态;当电动汽车处于溜坡状态时,加载非蠕行扭矩对电动汽车进行防溜坡控制;当电动汽车满足预设的蠕行条件时,卸载非蠕行扭矩,并发送电机退出防溜坡控制指令至整车控制器;整车控制器,用于当接收到电机退出防溜坡控制指令时,根据行驶状态确定整车控制器的蠕行扭矩;根据蠕行扭矩对电动汽车进行防溜坡控制。采用本系统可以避免电机堵转或超调,并能够按照驾驶员意图进行防溜坡控制。
