The invention provides a self-checking control method applied to a vehicle braking system, and belongs to the field of vehicle braking systems, brake fluid is pushed out through an auxiliary main cylinder piston to generate brake pressure, and the range of a tested hydraulic loop is controlled through an electromagnetic valve in the system. Whether leakage exists in the system or not is detected through the pressure change during pressurization-pressure maintaining or the corresponding relation between the piston stroke and the pressure during pressurization. After the whole vehicle is powered on or powered off, sealing performance detection is carried out on a hydraulic loop and a hydraulic component through self-inspection of an activation system, and it is ensured that the hydraulic system is free of leakage and other abnormal problems before working. The hydraulic fault is detected in advance, and the driving risk is reduced.
本发明提供一种应用于车辆制动系统的自检控制方法,属于车辆制动系统领域,通过副主缸活塞推出制动液产生制动压力,并通过系统内的电磁阀控制被测液压回路的范围。通过加压‑保压时的压力变化或检测加压时的活塞行程和压力的对应关系,进而检测出系统是否存在泄露。本发明在整车上电或下电后,通过激活系统自检对液压回路和液压部件进行密封性检测,确保液压系统在工作前无泄漏等异常问题。实现液压故障的提前检测,降低行驶风险。
