The invention discloses a method and a device for preventing an electric vehicle from sliding on a slope and electronic equipment. The method comprises the steps that under the condition that it is determined that the electric vehicle is in a slope sliding state, a motor is controlled to conduct a slope sliding prevention process; the slope sliding prevention process comprises at least one locked-rotor stage and at least one running stage, the locked-rotor stage comprises locked-rotor at a first set rotating speed, and the running stage comprises the step of controlling the electric vehicle to run forwards or backwards by controlling the rotating speed of a motor. On the basis of realizing the anti-slip function, the electric vehicle is controlled to advance or retreat by controlling the rotating speed of the motor, so that the motor is changed into an alternating current sine wave state in a normal driving state from a direct current heating state during stalling, and the purpose of reducing the temperature of a power module in the motor controller is achieved; the problem that according to an existing slope sliding prevention method, when the motor system is locked to achieve the slope sliding prevention function, the motor system cannot be locked continuously due to overheating, and the slope sliding prevention performance is poor is solved.
本发明公开了一种电动汽车防溜坡方法、装置及电子设备。其中方法包括:在确定电动汽车处于溜坡状态的情况下,控制电机进行防溜坡流程;防溜坡流程包括至少一个堵转阶段和至少一个行驶阶段,堵转阶段包括以第一设定转速进行堵转,行驶阶段包括通过控制电机的转速控制电动汽车向前行驶或后退。本发明在实现防溜坡功能的基础上,通过控制电机的转速控制电动汽车前进或后退,使电机由堵转时的直流发热状态,变为正常行驶状态下的交流正弦波状态,以达到降低电机控制器中的功率模块的温度的目的,解决了现有的防溜坡方法在采用电机系统堵转实现防溜坡功能时,存在电机系统会因为过热而无法持续堵转,导致防溜坡性能差的问题。
