The invention discloses an electronic hydraulic brake system which comprises a pedal, an oil can module, a brake master cylinder, a pressure buildup unit and a wheel brake unit, two brake pistons are arranged in the brake master cylinder in a sliding mode, and the two brake pistons divide the interior of the brake master cylinder into three brake cavities. Three brake cavities are formed in the brake master cylinder, brake control over the wheel brake unit can be achieved through cooperation of the pressure buildup unit and the first linkage electromagnetic valve or the second linkage electromagnetic valve in the decoupled state of the pedal and the brake master cylinder, and meanwhile a pressure buildup cylinder of the pressure buildup unit can communicate with the brake master cylinder and the wheel brake unit. And when the brake master cylinder and the wheel brake unit leak oil and fail, oil can be supplemented, so that oil leakage fault repair of the brake system is realized, and the safety redundancy capability of the brake system is further improved.

    本申请公开了一种电子液压制动系统,包括踏板、油壶模块、制动主缸、建压单元及车轮制动单元,制动主缸内部滑动设有两个制动活塞,两个制动活塞将制动主缸内部分隔为三个制动腔,本申请实施例中,采用上述的一种电子液压制动系统,于制动主缸内设置三个制动腔,于踏板、制动主缸解耦状态下,通过建压单元与第一联动电磁阀或第二联动电磁阀的配合,能够实现对车轮制动单元的制动控制,同时建压单元的建压缸能够与制动主缸、车轮制动单元连通,在制动主缸、车轮制动单元漏油失效时能够对其进行补油,从而实现制动系统的漏油故障修复,进一步提高制动系统的安全冗余能力。
