The invention discloses a braking energy recovery system of a hybrid vehicle and a braking energy recovery method thereof, the braking energy recovery system comprises a braking energy recovery system body, and a vehicle battery information SOC acquisition module and a vehicle brake pedal state information acquisition module on the braking energy recovery system body are mutually connected in parallel; the braking force judgment module, the energy recovery module, the braking pedal pressure switch module, the braking force distribution module and the braking force termination module are sequentially connected, the braking energy recovery system guarantees maximization of regenerative braking recovery, the braking energy recovery efficiency is further improved, hydraulic braking and an ABS are arranged, and the braking energy recovery efficiency is improved. And the braking energy recovery system is different from the mode that the hydraulic braking force is started when the regenerative braking force reaches the maximum value, the braking energy recovery control method is in an active working state, and the safety coefficient is improved.

    本发明公开了一种混动车辆的制动能量回收系统及其制动能量回收方法,包括制动能量回收系统本体,在制动能量回收系统本体上的车辆电池信息SOC采集模块与车辆制动踏板状态信息采集模块相互并联,制动力判断模块、能量回收模块、制动踏板压力开关模块、制动力分配模块、制动力终止模块依次连接,该制动能量回收系统保证了再生制动回收的最大化,进一步提高了制动能量回收效率,而且有液压制动有ABS防抱死系统,避免了车轮抱死发生滑移,而且该制动能量回收系统与再生制动力到达最大值再启动液压制动力不同,这种制动能量回收控制方法处于主动工作状态,安全系数得到提高。
