The invention provides a four-wheel-drive electric vehicle braking system and a braking adjusting method. The four-wheel-drive electric vehicle braking system comprises an ibooster braking control unit, an ABS, a VCU and an MCU motor controller, and the ibooster braking control unit and the VCU are connected with a braking pedal; the iboost braking control unit is connected with the VCU and the MCU motor controller through a CAN bus, the iboost braking control unit and the ABS are used for hydraulic braking, and the MCU motor controller and the driving motor are used for motor braking. According to the four-wheel-drive electric vehicle braking system and the braking adjusting method, electric braking force preferential braking and hydraulic braking force auxiliary braking are achieved, the braking anti-lock function is achieved only by means of the electric braking force on a low-attachment road surface, electric braking preferential braking and hydraulic braking compensation adjusting are achieved on a middle-high-attachment road surface, and the braking anti-lock function is achieved. And the energy consumption of the whole vehicle is reduced in the braking process.

    本发明提供了一种四驱电动汽车制动系统及制动调节方法,包括ibooster制动控制单元、ABS防抱死单元、VCU整车控制器以及MCU电机控制器,所述ibooster制动控制单元以及所述VCU整车控制器与所述制动踏板连接,所述ibooster制动控制单元与所述VCU整车控制器以及所述MCU电机控制器通过CAN总线相互连接,所述ibooster制动控制单元与ABS用于液压刹车,所述MCU电机控制器与驱动电机用于电机刹车。本发明的一种四驱电动汽车制动系统及制动调节方法,电制动力优先制动,液压制动力辅助制动,在低附路面单纯依靠电制动力实现制动防抱死功能,在中高附路面电制动优先制动,液压制动补偿调节,实现制动防抱死功能,制动过程减小了整车能耗。
