The invention discloses a slope sliding control method for a pure electric vehicle under the extreme working condition. The slope sliding control method comprises the steps that S10, whether the pure electric vehicle is in the slope sliding working condition currently or not is monitored in real time; s11, when the vehicle is in the slope sliding working condition, whether the vehicle is in the extreme working condition or not is recognized; s12, when the vehicle is in the extreme working condition, whether the current vehicle has the anti-slip intention or not is recognized; s13, when it is recognized that the current vehicle has the anti-slip intention, a heating system of a high-voltage power battery is started so as to improve the allowable power generation power of a driving motor; and S14, after it is monitored that the preset closing condition is met, the heating system of the high-voltage power battery is closed. The invention further discloses a corresponding system. By implementing the embodiment of the invention, the safety of the pure electric vehicle can be improved.

    本发明公开了一种纯电动车辆极端工况溜坡控制方法,其包括步骤:步骤S10,实时监测纯电动车辆当前是否处于溜坡工况;步骤S11,在车辆处于溜坡工况时,识别其是否处于极端工况;步骤S12,在车辆处于极端工况时,识别当前车辆是否具备防溜坡的意图;步骤S13,在识别到当前车辆具备防溜坡的意图时,启动高压动力电池的加热系统,以提升驱动电机的允许发电功率;步骤S14,在监测到预定的关闭条件成立后,关闭所述高压动力电池的加热系统。本发明还公开了相应的系统。实施本发明的实施例,可以提高纯电动车辆的安全性。
