The invention relates to a vehicle auxiliary braking method and device, computer equipment and a storage medium. The method comprises the steps that when a vehicle is in a sliding state, the initial speed and the final speed in unit time are obtained; if it is determined that the vehicle is in a downhill working condition according to a first speed difference value between the initial speed and the final speed, whether the vehicle meets an auxiliary braking control condition currently or not is determined; if so, an auxiliary braking control mode is started, and when the real-time vehicle speed is larger than the initial speed, an auxiliary braking torque value is determined based on a second speed difference value between the real-time vehicle speed and the initial speed; and the auxiliary braking torque value is sent to a motor controller of the vehicle, so that the motor controller controls a motor of the vehicle to conduct auxiliary braking based on the auxiliary braking torque value. By adopting the method, the vehicle braking effect can be improved.

    本申请涉及一种车辆辅助制动方法、装置、计算机设备和存储介质。所述方法包括:当车辆处于滑行状态时,获取单位时间内的起始速度和最终速度;若根据所述起始速度和最终速度间的第一速度差值确定所述车辆处于下坡工况,则确定所述车辆当前是否满足辅助制动控制条件;若满足,则进入辅助制动控制模式,并在实时车速大于所述起始速度时,基于所述实时车速和所述起始速度间的第二速度差值,确定辅助制动转矩值;将所述辅助制动转矩值发送至所述车辆的电机控制器,以通过所述电机控制器基于所述辅助制动转矩值控制所述车辆的电机进行辅助制动。采用本方法能够提高车辆制动效果。
