An electric control hydraulic braking system comprises an oil tank, a first cylinder, a second cylinder, a driving part, a liquid inlet valve, a selector valve, a wheel cylinder, a first liquid path and a second liquid path. The first cylinder and the second cylinder are connected to the oil tank, the driving part is connected to the second cylinder, the wheel cylinder is connected to the liquid inlet valve, the first liquid path is arranged between the first cylinder and the liquid inlet valve, the second liquid path is arranged between the second cylinder and the liquid inlet valve, a forward control valve and a first reverse control valve are arranged on the second liquid path, one of the first liquid path and the second liquid path is selectively communicated with the liquid inlet valve, and the selector valve is used for selectively communicating the first liquid path with the liquid inlet valve or communicating the second liquid path with the liquid inlet valve. According to theelectronic 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 system is high in integrationdegree, light in weight, relatively low in cost and relatively obvious in product advantages.
