The invention relates to the technical field of vehicle driving, in particular to an anti-slope-sliding control method and device for a vehicle, and the method comprises the steps: detecting whether the vehicle is in a slope-sliding working condition or not; when it is detected that the vehicle is in the slope sliding working condition, the vehicle speed change rate and the current torque value after the vehicle enters the slope sliding working condition are obtained, and the current running resistance coefficient of the vehicle is calculated according to the vehicle speed change rate and the current torque value; and according to the current running resistance coefficient, the current anti-slope-sliding torque of the vehicle is calculated, and motor output of the vehicle is controlled according to the current anti-slope-sliding torque. According to the embodiment of the invention, the anti-slip torque can be obtained based on the vehicle speed and the torque change, and the anti-slip torque is used as the vehicle control torque, so that the anti-slip effect of the obtained torque is better, the anti-slip torque better conforms to the actual driving condition of the vehicle, and the reliability of the anti-slip function of the vehicle is improved.

    本申请涉及车辆驱动技术领域,特别涉及一种车辆的防溜坡控制方法及装置,其中,方法包括:检测车辆是否处于溜坡工况;在检测到车辆处于溜坡工况的情况下,获取车辆进入溜坡工况后的车速变化率与当前扭矩值,并根据车速变化率与当前扭矩值计算车辆的当前行驶阻力系数;根据当前行驶阻力系数计算车辆的当前防溜坡扭矩,并根据当前防溜坡扭矩控制车辆的电机输出。本申请实施例可以基于整车车速与扭矩变化获取防溜坡扭矩,并将防溜坡扭矩作为整车控制扭矩,使所得扭矩的防溜坡效果更好,更符合车辆的实际驾驶状况,提升了车辆防溜坡功能的可靠性。
