The embodiment of the invention discloses a steep slope slow descent method and device of a vehicle, the vehicle and a storage medium. The method comprises the steps that real-time vehicle parameters of a vehicle are obtained, and whether the vehicle meets the condition of entering a steep slope slow descent mode or not is judged according to the real-time vehicle parameters; if the vehicle meets the condition of entering the abrupt slope slow descent mode, the vehicle speed when the vehicle enters the abrupt slope slow descent mode serves as the target vehicle speed of the vehicle in the abrupt slope slow descent mode, and the braking feedback torque is calculated according to the target vehicle speed; and controlling the driving motor to execute the brake feedback torque. According to the embodiment of the invention, the latched target vehicle speed is high in flexibility and can adapt to different road condition scenes, the braking feedback torque is executed through the driving motor to achieve stable driving of the vehicle, and meanwhile energy can be recycled to the battery pack.

    本申请的实施例揭示了一种车辆的陡坡缓降方法、装置、车辆及存储介质。该方法包括:获取车辆的实时车辆参数,并根据所述实时车辆参数判断所述车辆是否满足进入陡坡缓降模式的条件;若所述车辆满足进入陡坡缓降模式的条件,则将所述车辆进入陡坡缓降模式时的车速作为所述车辆在陡坡缓降模式下的目标车速,并根据所述目标车速计算制动回馈扭矩;控制驱动电机执行所述制动回馈扭矩。本申请的实施例中锁存的目标车速的灵活性高,可适应不同的路况场景,并通过驱动电机执行制动回馈扭矩实现车辆平稳驾驶的同时,还能实现能量回收到电池包。
