The invention relates to a control method for preventing an electric vehicle from sliding on a slope, a vehicle control unit and an electric vehicle. The method comprises the following steps: when it is detected that the electric vehicle climbs and starts, the vehicle control unit collects slope information of a road surface through a slope sensor; the acquired gradient information of the road surface is compared with a first preset gradient; when the collected gradient information of the road surface is smaller than the first preset gradient, the vehicle is normally controlled to run in a low-speed wriggling mode; and when the collected gradient information of the road surface is larger than the first preset gradient, a motor is controlled to output higher torque to control the vehicle to run in a low-speed wriggling mode according to preset torque correction coefficients corresponding to different gradients. The corresponding torque can be accurately provided for the vehicle, so that the electric vehicle can be stably started, the slope sliding behavior is avoided, and resource waste is avoided.

    所述发明涉及一种电动汽车防溜坡的控制方法、整车控制器及电动汽车,所述方法包括以下步骤:当检测到电动汽车爬坡起步时,整车控制器通过坡度传感器采集路面的坡度信息;将采集的路面的坡度信息与第一预设坡度进行比对;当采集的路面的坡度信息小于第一预设坡度时,则正常控制车辆低速蠕动行驶;当采集的路面的坡度信息大于第一预设坡度时,则根据预设的不同坡度对应的扭矩修正系数,控制电机输出更高的扭矩控制车辆低速蠕动行驶。可以精准为车辆提供相应的扭矩,使得电动汽车可以稳定起步,避免出现溜坡行为,以及避免资源的浪费。
