The invention provides a slope sliding prevention control system and method for an electric vehicle, and relates to the technical field of vehicle slope sliding prevention, and the system comprises: a data acquisition module which is used for acquiring the operation data of the vehicle, and outputting a control signal when the operation data represents that the vehicle runs on a ramp under full power and a motor of the vehicle is in a reverse rotation state; and a control module which is connected with the data acquisition module, and is used for starting at least one high-voltage accessory of the vehicle according to the control signal, obtaining the actual consumption power of the high-voltage accessory, and then controlling the motor to provide a reverse driving force with a motor feedback power not greater than the actual consumption power so as to prevent the vehicle from sliding on the slope. The system and method have the beneficial effects that the motor can provide reverse driving force when a vehicle battery is fully charged, so that the vehicle is prevented from sliding on a slope, and the user experience is effectively improved; by means of the mode of starting the high-voltage accessory, power generated when the motor provides the reverse driving force can be consumed by the high-voltage accessory, feedback is not generated on the battery, and effective protection of the vehicle battery is achieved.

    本发明提供一种电动车防溜坡控制系统及方法,涉及车辆防溜技术领域,包括:一数据采集模块,用于采集车辆的运行数据,并在运行数据表示车辆满电运行于一坡道上且车辆的电机处于反转状态时输出一控制信号;一控制模块,连接数据采集模块,用于根据控制信号开启车辆的至少一高压附件,并获取高压附件的实际消耗功率,随后控制电机以不大于实际消耗功率的一电机回馈功率提供一反向驱动力,防止车辆溜坡。有益效果是电机能够在车辆电池满电时提供反向驱动力,进而防止车辆溜坡,有效提升用户使用体验;通过开启高压附件的方式,使得电机提供反向驱动力时的发电能够被高压附件消耗,进而对电池不产生回馈,实现对车辆电池的有效保护。
