The invention discloses a braking energy recovery control method of an electric automobile and the electric automobile, wherein the control method comprises the steps: S1, when the electric automobile meets a set braking energy recovery condition, a whole automobile controller authorizes the control right of a driving motor to an automobile body stability control system; and S2, the automobile body stability control system controls a braking system of the electric automobile to execute single motor braking, single hydraulic braking or coordinated braking of a driving motor and a hydraulic executing mechanism. According to the braking energy recovery control method of the electric automobile, the control method that the whole automobile controller authorizes the control right of the whole automobile driving motor to the automobile body stability control system during braking energy recovery is adopted, so that closed-loop control of the braking system is facilitated; therefore, the driving motor and the hydraulic actuating mechanism can perform cooperative braking response in a shorter time, and the braking stability and the maximum energy recovery are ensured under the condition that the hardware cost is not increased.

    本发明公开了一种电动汽车的制动能量回收控制方法及电动汽车,所述控制方法包括:步骤S1,当电动汽车满足设定制动能量回收条件时,整车控制器将驱动电机的控制权授权给车身稳定控制系统;步骤S2,所述车身稳定控制系统控制所述电动汽车的制动系统执行单一电机制动、单一液压制动或驱动电机与液压执行机构协调制动。根据本发明的电动汽车的制动能量回收控制方法,通过采取在制动能量回收时,整车控制器将整车驱动电机的控制权授权给车身稳定控制系统的控制方法,有利于制动系统闭环控制,使得驱动电机与液压执行机构能在更短的时间内进行协同制动响应,在不增加硬件成本的情况下保证了制动的稳定性和能量回收最大化。
