The invention relates to a brake master cylinder assembly, a brake system and a brake system control method, the brake master cylinder assembly comprises a brake master cylinder, the brake master cylinder comprises a cylinder body and a piston push rod arranged in the cylinder body, the cylinder body is provided with an oil inlet and an oil outlet, and the piston push rod is used for being connected with a brake pedal. The cylinder body is provided with a switch valve, the switch valve is located at the oil inlet, and the switch valve is used for controlling the oil inlet to be opened and closed according to the movement process of the brake pedal. Due to the fact that the switch valve is arranged at the oil inlet, when the brake pedal is treaded down, the switch valve directly operates to block the oil inlet without the needed to wait for the piston push rod to move to block the oil inlet, and therefore the response sensitivity during braking is improved, and the idle stroke at the initial stage of braking is shortened.
本发明涉及一种制动主缸组件、制动系统和制动系统控制方法,制动主缸组件,包括制动主缸,所述制动主缸包括缸体和设置在所述缸体中的活塞推杆,所述缸体上设有进油口和出油口,所述活塞推杆用于与制动踏板连接,所述缸体上设有开关阀,所述开关阀位于所述进油口处,所述开关阀用于根据所述制动踏板的运动过程控制所述进油口开关。通过在所述进油口处设置所述开关阀,当制动踏板被踩下时,所述开关阀直接运作将所述进油口封堵,而无需等待所述活塞推杆移动来将所述进油口封堵,从而提升制动时反应的灵敏性,同时缩短制动初期空行程。
