An electric control hydraulic braking system comprises an oil tank, a first cylinder, a second cylinder, a driving part, a liquid inlet valve, a wheel cylinder, a first liquid path, a first isolationvalve, a second liquid path and a liquid outlet valve. The driving part drives a first piston of the second cylinder to move, the wheel cylinder is connected to the liquid inlet valve, the first liquid path is located between the first cylinder and the liquid inlet valve, the first isolation valve is arranged on the first liquid path, the second liquid path is arranged between the second cylinderand the liquid inlet valve, a forward control valve and a reverse control valve are arranged on the second liquid path, and the liquid outlet valve is connected between the wheel cylinder and the oiltank. According to the electronic control hydraulic braking system, four braking modes can be achieved through the design of the oil paths, the braking requirement during electronic control failure can be met, the system reliability is high, various different braking force requirements can be met, and the requirements for the braking system in current intelligent driving can be met; and the systemis high in integration degree, light in weight, relatively low in cost and relatively obvious in product advantages.
