The invention discloses a slope slip prevention control method and device of an electric vehicle, a storage medium and a controller, and the anti-slip control method of the electric vehicle comprises the following steps: obtaining a whole vehicle power supply gear signal; after it is determined that the electric vehicle completes high-voltage power-on according to the whole vehicle power supply gear signal, obtaining a gear signal of the electric vehicle, and obtaining the motor rotating speed of the electric vehicle; when it is determined that the electric vehicle is currently in the driving gear according to the gear signal of the electric vehicle, judging whether the electric vehicle needs to be subjected to anti-slip control according to the motor speed; and if the electric vehicle needs to be subjected to slope sliding prevention control, performing rotating speed PI (Proportional Integral) control on a driving motor of the electric vehicle according to the difference value between the rotating speed of the motor and the target rotating speed. Therefore, according to the slope slip prevention control method for the electric vehicle, the vehicle can be controlled to prevent slip through software, the control cost is reduced, and meanwhile the slope slip prevention effect can be improved.
本发明公开了一种电动车辆的防溜坡控制方法与装置、存储介质、控制器,其中,电动车辆的防溜坡控制方法包括以下步骤:获取整车电源档位信号;根据整车电源档位信号确定电动车辆完成高压上电后,获取电动车辆的档位信号,并获取电动车辆的电机转速;根据电动车辆的档位信号确定电动车辆当前处于驱动档位时,根据电机转速判断电动车辆是否需要进行防溜坡控制;如果电动车辆需要进行防溜坡控制,则根据电机转速与目标转速之间的差值对电动车辆的驱动电机进行转速PI(Proportion Integral,比例积分)控制。由此,该电动车辆的防溜坡控制方法,能够通过软件控制车辆防溜坡,降低控制成本,同时能够提高防溜坡效果。
