The invention provides a vehicle control method and device, a storage medium and a vehicle, and belongs to the technical field of vehicles. According to the embodiment of the invention, under the conditions that the vehicle is in a downhill working condition and a motor is in a sliding energy recovery state, the current gradient and the historical gradient of the previous moment are obtained; a braking torque adjustment value can be determined based on the current gradient and the historical gradient; and the current motor braking torque of the motor is adjusted based on the braking torque adjusting value. According to the embodiment of the invention, when the vehicle is in the downhill working condition, the current motor braking torque is synchronously adjusted timely and accurately according to the change of the road gradient, so that the driving stability and safety of the vehicle can be improved while the maximum energy recovery of the motor is ensured, and the driving experience of a user is effectively improved.

    本申请提供了一种车辆控制方法、装置、存储介质和车辆,属于车辆技术领域,本申请实施例通过在车辆处于下坡工况且电机处于滑行能量回收状态的情况下,获取当前坡度与上一时刻的历史坡度;能够基于当前坡度和历史坡度,确定制动扭矩调节值;进而基于制动扭矩调节值,对电机的当前电机制动扭矩进行调整。本申请实施例通过在车辆处于下坡工况时,根据道路坡度的变化,及时准确地对当前电机制动扭矩进行同步调整,能够在保证电机能量回收最大化的同时,提高车辆的行驶平稳性和安全性,进而有效改善用户的驾驶体验。
