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.
