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.

    一种电控液压制动系统包括油箱、第一缸、第二缸、驱动件、进液阀、轮缸、第一液路、第一隔离阀、第二液路和出液阀,驱动件连驱动第二缸的第一活塞移动,轮缸连接于进液阀,第一液路位于第一缸和进液阀之间,第一隔离阀位于第一液路上,第二液路设于第二缸和进液阀之间,第二液路上设有前向控制阀和反向控制阀,出液阀连接于轮缸和油箱之间。本发明的电控液压制动系统,通过油路的设计,可实现四种制动模式,既能满足电控失效时的制动需求、系统可靠性较高,又能满足多种不同制动力需求,能适应当前智能驾驶中对制动系统的要求;且系统集成度高、重量轻、相对成本较低,产品优势较为明显。
