The invention belongs to the technical field of electric vehicles, and discloses an electric vehicle slope sliding control method which comprises the steps that 101, if a brake pedal signal, a hand brake signal and an accelerator pedal opening signal are invalid, a gear signal is valid, a forward gear is engaged, the detected vehicle speed is opposite to the gear direction, and the speed is largerthan or equal to a preset judgment value; if so, controlling the electric vehicle to enter an anti-slip mode; 102, after the electric vehicle enters the anti-slope-sliding mode for a period of presettime, the electric vehicle is controlled to exit from the anti-slope-sliding mode and enter a speed limiting mode, and after a period of preset time, returning to the step 101; 103, if the accelerator pedal signal is valid, the electric vehicle is controlled to exit from the anti-slope-sliding mode or the speed limiting mode, and normal operation is maintained; and if the brake pedal signal or the hand brake signal is valid, the electric vehicle is controlled to quit the anti-slope-sliding or speed-limiting mode, and the vehicle is made to enter a brake state. The safety performance of slopesliding of the electric vehicle can be improved.
本发明属于电动车辆技术领域,公开了一种电动车辆溜坡的控制方法,包括:101、若制动踏板信号、手刹信号和油门踏板开度信号都无效,档位信号有效且挂前进挡,检测到的车辆速度与档位方向相反且速度大于等于预设判断值,则控制电动车辆进入防溜坡模式;102、当电动车辆进入防溜坡模式后,经过一段预设时间后,控制电动车辆退出防溜坡模式,进入限速模式,再经过一段预设时间后,返回步骤101;103、若油门踏板信号有效,控制电动车辆退出防溜坡模式或限速模式,维持正常运行;若制动踏板信号或手刹信号有效,控制电动车辆退出防溜坡或限速模式,使车辆进入制动状态。本发明能够提高电动车辆溜坡的安全性能。
