The invention discloses an electric vehicle anti-slip and ramp crawling torque control method and system and a vehicle, and the method comprises the following steps: obtaining a gradient signal, and calculating the gradient value of a current road based on the gradient signal; when the slope value of the current road is judged to be within the preset slope value range in response, the anti-slope-sliding torque is calculated based on the obtained slope signal, and the anti-slope-sliding torque refers to the request torque when the vehicle is static on the slope; when it is detected that the brake of the vehicle is loosened on the ramp, the vehicle speed of the vehicle is obtained, and the ramp crawling torque of the corresponding vehicle speed is calculated according to the current vehicle speed; and adding the anti-slip torque and the ramp crawling torque to serve as the request torque of the vehicle on the ramp, so that the vehicle slowly crashes on the ramp. The anti-slip function is achieved, and meanwhile the vehicle can be maintained to slowly creep on the ramp after the brake is loosened.

    本发明公开了一种电动车防溜坡和坡道蠕行扭矩控制方法、系统及车辆,包括以下步骤:获取坡度信号,基于坡度信号计算出当前道路的坡度值;响应于判断出当前道路的坡度值在预设坡度值范围内时,基于获取的坡度信号计算出防溜坡扭矩,所述防溜坡扭矩是指车辆在坡道上静止时的请求扭矩;响应于检测到车辆在坡道上松刹车时,获取车辆的车速,并根据当前车速计算对应车速的坡道蠕行扭矩;将防溜坡扭矩和坡道蠕行扭矩相加并作为车辆在坡道时的请求扭矩,使车辆在坡道上缓慢蠕行。本发明实现了防溜坡功能,同时还能够维持车辆在坡道上松刹车后缓慢蠕行。
