The invention discloses an electric vehicle, an energy recovery control method and device thereof, a storage medium and a vehicle control unit. The electric vehicle comprises a brake deflector rod. The control method comprises the following steps: obtaining vehicle speed information, power battery information and driving motor information of the electric vehicle; judging whether the electric vehicle is allowed to perform deflector rod electric braking energy recovery or not according to the acquired information; if so, acquiring a braking demand torque according to the braking stroke of the braking deflector rod and the vehicle speed information, acquiring a power battery limiting torque according to the power battery information, and acquiring a driving motor limiting torque according tothe driving motor information; and obtaining electric braking torque according to the braking demand torque, the power battery limiting torque and the driving motor limiting torque, and enabling a driving motor of the electric vehicle to generate power according to the electric braking torque. Therefore, the energy recovery control method of the electric vehicle can improve the endurance of the electric vehicle, ensure the driving safety of the electric vehicle and improve the energy recovery efficiency.

    本发明公开了一种电动汽车及其能量回收控制方法与装置、存储介质、整车控制器,其中,电动汽车包括制动拨杆,控制方法包括以下步骤:获取电动汽车的车速信息、动力电池信息和驱动电机信息;根据所获取的信息判断是否允许电动汽车进行拨杆电制动能量回收;如果允许,则根据制动拨杆的制动行程和车速信息获取制动需求扭矩,根据动力电池信息获取动力电池限制扭矩,并根据驱动电机信息获取驱动电机限制扭矩;根据制动需求扭矩、动力电池限制扭矩和驱动电机限制扭矩获取电制动扭矩,并根据电制动扭矩控制电动汽车的驱动电机进行发电。由此,该电动汽车的能量回收控制方法能够提高电动汽车的续航能力,保证电动汽车的行驶安全,同时提高能量回收效率。
