The invention discloses an energy recovery control method, an energy recovery control device, a vehicle and a storage medium, and the energy recovery control method comprises the steps that when a braking instruction is received, whether a torque zero-crossing working condition exists in a driving motor or not is determined; and when it is determined that the driving motor has the torque zero-crossing working condition, the driving motor is controlled to conduct energy recovery according to the preset torque, the preset torque is smaller than a preset torque threshold value, and the preset torque threshold value is used for representing a pause torque value generated by the driving motor under the torque zero-crossing working condition. According to the method, when the driving motor is in the torque zero-crossing working condition, the driving motor is controlled to conduct energy recovery according to the preset torque, the situation that the driving motor generates pause due to too fast torque change under the torque zero-crossing working condition can be avoided, and the driving stability of the electric automobile in the energy recovery process is improved.
本申请公开了一种能量回收控制方法、能量回收控制装置、车辆及存储介质,能量回收控制方法,包括:当接收到制动指令时,确定驱动电机是否存在扭矩过零工况;当确定驱动电机存在扭矩过零工况时,根据预设扭矩控制驱动电机进行能量回收,预设扭矩小于预设扭矩阈值,预设扭矩阈值用于表征驱动电机在扭矩过零工况下产生顿挫的扭矩值。本方法实现了在驱动电机处于扭矩过零工况时,根据预设扭矩控制驱动电机进行能量回收,可避免驱动电机在扭矩过零工况下因扭矩变化太快产生顿挫,提高了电动汽车在能量回收过程中的驾驶稳定性。
