The invention relates to the technical field of energy recovery, and provides an electric vehicle coordination type energy recovery method which specifically comprises the following steps that S1, whether a vehicle is in an emergency braking state or not is detected; and S2, if the detection result is yes, the front axle and the rear axle are braked in a hydraulic braking mode, and if the detection result is no, the front axle is braked in the mode that regenerative braking is used as a main mode and hydraulic braking is used as an auxiliary mode, and the rear axle is braked in the hydraulic braking mode. According to the energy recovery method, regenerative braking is adopted as much as possible on the premise that the safety of the vehicle is guaranteed, energy recovery is carried out, the endurance mileage of the electric vehicle is increased, and the endurance anxiety of the electric vehicle is relieved.

    本发明涉及能量回收技术领域,提供了一种电动车协调式能量回收方法,所述方法具体包括如下步骤:S1、检测车辆是否处于紧急制动状态;S2、若检测结果为是,则前轴、后轴通过液压制动方式进行制动,若检测结果为否,则前轴以再生制动为主,液压制动为辅的方式进行制动,后轴采用液压制动方式进行制动。本发明提供能量回收方法在保证车辆安全的前提下尽可能的采用再生制动,进行能量的回收,以在增大电动汽车的续航里程,缓解电动汽车的续航焦虑。
