The invention provides a vehicle slope sliding prevention method, device and equipment, a storage medium and a product. The method comprises the steps that when it is determined that a vehicle is in a slope sliding state according to real-time braking data, the rotating speed of a motor, the rotating direction of the motor and gear data, the torque output direction is determined according to the slope sliding state, and a slope sliding mark is generated; and determining the amplitude of a target compensation torque and a target output rate corresponding to the slope threshold, and determining the amplitudes of real-time compensation torques corresponding to different moments based on the target compensation torque and the target output rate, thereby outputting the real-time compensation torque with the amplitude gradually increased at a gradually reduced output rate based on the torque output direction. The slope sliding distance generated by the vehicle under the working condition of gentle slope and tiny slope sliding is reduced, the accuracy and stability of vehicle anti-slope-sliding control are improved, the vehicle shaking phenomenon is relieved, and the driving experience is improved.
本申请提供一种车辆防溜坡方法、装置、设备、存储介质以及产品。该方法包括:通过实时制动数据、电机转速、电机转动方向和档位数据确定车辆为溜坡状态时,根据溜坡状态确定扭矩输出方向并生成溜坡标识,基于溜坡标识确定车辆溜坡的坡度数据低于坡度阈值时,确定该坡度阈值对应的目标补偿扭矩的幅值和目标输出速率,基于目标补偿扭矩和目标输出速率确定不同时刻对应的实时补偿扭矩的幅值,从而基于扭矩输出方向以逐渐减小的输出速率输出幅值逐渐增大的实时补偿扭矩。减小了车辆在缓坡微小溜坡工况下产生的溜坡距离,提升车辆防溜坡控制的精准性和稳定性,减轻车辆抖动现象,提升驾驶体验。
