The invention relates to the technical field of automobile braking energy recovery, in particular to an electric automobile braking energy recovery device and method. An initial stage simulator comprises a shell, a connecting frame, a limiting sleeve, a guide sleeve, a spring I, a spring II and a spring III; one side of the shell is connected with a sealing cover, one end of the shell is connected with a vacuum booster, and the connecting frame is used for being hinged to a brake pedal of the electric automobile; the limiting sleeve is arranged on one side in the shell, the spring III is arranged on the inner side of the limiting sleeve, one side of the spring III makes contact with the guide sleeve, a protruding part on the outer side of the guide sleeve makes contact with the spring II, the inner side of the guide sleeve makes contact with the spring I, the spring rigidity of the spring I, the spring II and the spring III is gradually increased, and the spring rigidity of the spring III is smaller than that of a valve spring in the vacuum booster. The electric braking force of the driving motor is properly increased to ensure the required braking force, the intervention frequency and the intervention pressure value of hydraulic braking are effectively reduced, and vehicle energy recovery is effectively increased.

    本发明涉及汽车制动能量回收技术领域,具体涉及一种电动汽车制动能量回收装置及回收方法,初段模拟器包括壳体、连接架、限位套、导向套、弹簧Ⅰ、弹簧Ⅱ、弹簧Ⅲ;壳体一侧设有密封盖连接,壳体的一端与真空助力器连接,连接架用于与电动汽车的制动踏板铰接;限位套设置在壳体内部一侧,弹簧Ⅲ设置在限位套内侧,弹簧Ⅲ一侧与导向套接触,导向套外侧上凸起部与弹簧Ⅱ接触,内侧与弹簧Ⅰ接触,弹簧Ⅰ、弹簧Ⅱ与弹簧Ⅲ的弹簧刚度逐渐增大,弹簧Ⅲ小于真空助力器中阀门弹簧的弹簧刚度。本发明过适当增加驱动电机的电制动力来确保需求制动力,有效的降低液压制动的介入次数与介入压力值,有效的增加了车辆能量回收。
