The invention discloses a control method for safe driving of an electric automobile, the electric automobile and a storage medium. The control method comprises the step of starting control over the vehicle on the low slope-attached road surface, and comprises the steps that when the vehicle speed is smaller than or equal to the critical vehicle speed, a hand brake is relieved, a transmission is located at the gear D, and the rotating speed of a power motor is zero, a first anti-slope-slipping mode is activated, and if the first anti-slope-slipping mode fails, and the rotation direction of the power motor requested by the vehicle control unit is opposite to the actual rotation direction of the power motor, second anti-slope-sliding mode is entered; if the two anti-slope-sliding modes are invalid, and if the vehicle speed is larger than the critical vehicle speed and the rotation direction of the power motor requested by the vehicle control unit is opposite to the actual rotation direction of the power motor, a driver is prompted to implement driving braking. According to the control strategy for starting the vehicle on the low-slope-attachment road surface, safety accidents caused by slope slipping of the vehicle are avoided through the dual anti-slope-slipping mode, and safe driving control over the electric vehicle is perfected.

    本发明公开了一种电动汽车安全驾驶的控制方法、电动汽车及存储介质。控制方法包括车辆在低附坡路面的启动控制,包括步骤:当车速小于等于临界车速、手刹解除、变速器位于D档、且动力电机的转速为零时,激活第一重防溜坡模式:若第一重防溜坡模式失效,且此时所述整车控制器请求的动力电机转动方向与动力电机实际的转动方向相反,则进入第二重防溜坡模式:若两种防溜坡模式均失效,且此时车速大于所述临界车速、所述整车控制器请求的动力电机转动方向与动力电机的实际转动方向相反,则提示驾驶员实施行车制动。本发明提供的低附坡路面进行车辆启动时的控制策略,通过双重防溜坡模式来确保车辆不会溜坡引发安全事故,完善了电动汽车安全驾驶控制。
