The invention provides a downhill working condition sliding feedback torque control method and device, a vehicle and a medium, and the method comprises the steps: determining the driving working condition of a target vehicle according to the driving parameters of the target vehicle; when the driving working condition of the target vehicle is the downhill working condition, determining a first gradient grade of the gradient where the target vehicle is located according to the initial acceleration of the target vehicle; a first sliding torque value corresponding to the first gradient grade is matched according to a preset gradient torque corresponding relation; and generating a first sliding torque instruction according to the first sliding torque value, and sending the first sliding torque instruction to a motor controller. According to the invention, the pause feeling of energy recovery in the downhill sliding process can be weakened, the riding experience of a user is improved, the energy recovery effect is better, and both the safety and the energy recovery efficiency are considered.

    本发明提供的一种下坡工况滑行回馈扭矩控制方法、装置、车辆及介质,该方法包括:根据目标车辆的行驶参数,确定目标车辆的行驶工况;当目标车辆的行驶工况为下坡工况时,根据目标车辆的初始加速度,确定目标车辆所处坡度的第一坡度等级;根据预设坡度扭矩对应关系,匹配与第一坡度等级对应的第一滑行扭矩值;根据第一滑行扭矩值生成第一滑行扭矩指令,向电机控制器发送第一滑行扭矩指令。本发明可以削弱在下坡滑行过程能量回收出现的顿挫感,提升用户的乘坐体验,能量回收效果更佳,兼顾安全性与能量回收效率。
