The invention relates to the technical field of vehicles, in particular to an energy recovery control method and device, a vehicle and a storage medium. The energy recovery control method comprises the steps that the current running speed and the brake pedal opening degree of the vehicle are obtained, and when it is judged that the vehicle meets the preset energy recovery condition according to the current running speed and the brake pedal opening degree, energy recovery is conducted; the current request braking torque is determined according to the opening degree of the braking pedal, the current temperature and the maximum output braking force of the driving motor are obtained, the current energy recovery torque of the driving motor is determined accordingly, and energy recovery is conducted according to the current request braking torque and the current energy recovery torque. Therefore, the problem that when the temperature of the driving motor is too high or the vehicle speed is too low, the braking safety and stability of the vehicle, the energy recovery power and the driving experience of a user are affected is solved, the braking force is distributed for the driving motor and the brake according to the temperature of the driving motor and the magnitude of the braking force requested by the vehicle, and then energy recovery is conducted. Therefore, the continuous stability of vehicle braking and the braking energy recovery power are improved.

    本申请涉及车辆技术领域,特别涉及一种能量回收控制方法、装置、车辆及存储介质,包括:获取车辆的当前行驶速度和制动踏板开度,在根据当前行驶速度和制动踏板开度判定车辆满足预设能量回收条件时,进而根据制动踏板开度确定当前请求制动力矩,并获取驱动电机的当前温度和最大可输出制动力,从而确定驱动电机的当前能量回收扭矩,并根据当前请求制动力矩和当前能量回收扭矩进行能量回收。由此,解决了驱动电机温度过高或者车速过低时,影响车辆的制动安全稳定性、能量回收功率以及用户的驾乘体验的问题,根据驱动电机温度和车辆请求制动力大小为驱动电机和制动器分配制动力进而进行能量回收,从而提高车辆制动的持续稳定性以及制动能量回收功率。
