The invention discloses a method and a device for preventing a vehicle from sliding on a slope for an electric vehicle. The method comprises the steps that whether a vehicle is located on a slope or not is determined according to driving data of the vehicle; under the condition that it is determined that the vehicle is located on the slope, the anti-slope-sliding torque used for preventing the vehicle from sliding on the slope is determined according to the driving data; determining whether the vehicle meets a predetermined anti-slip condition or not; and under the condition that it is determined that the vehicle meets the preset anti-slope-sliding condition, an inverter of the vehicle is controlled to output the anti-slope-sliding torque so as to prevent the vehicle from sliding on the slope. According to the method and the device for preventing the vehicle from sliding on the slope for the electric vehicle, whether the vehicle is located on the slope or not can be determined according to the driving data of the vehicle, and an additional sensor for detecting the slope does not need to be arranged; and under the condition that the vehicle meets the anti-slope-sliding condition, the inverter of the vehicle can output the anti-slope-sliding torque aiming at the current slope condition, the accuracy of preventing the vehicle from sliding on the slope is improved, and the cost of the vehicle is reduced.

    本发明公开了一种用于电动车辆的防止车辆溜坡的方法和装置。所述方法包括:根据车辆的行驶数据,确定车辆是否位于坡路上;在确定车辆位于坡路上的情况下,根据行驶数据确定用于防止车辆溜坡的防溜坡扭矩;确定车辆是否满足预定防溜坡条件;在确定车辆满足所述预定防溜坡条件的情况下,控制车辆的逆变器输出所述防溜坡扭矩,以防止车辆溜坡。根据本发明的用于电动车辆的防止车辆溜坡的方法和装置,能够根据车辆的行驶数据来确定车辆是否位于坡路上,而无需设置另外的用于检测坡度的传感器;并且在车辆满足防溜坡条件的情况下,能够使车辆的逆变器输出针对当前坡路情况的防溜坡扭矩,提高了防止车辆溜坡的准确度,并降低了车辆的成本。
