The invention discloses a full-decoupling type brake-by-wire system power-on piston forward-pushing zeroing method and system, and relates to the technical field of vehicle braking The full-decoupling type brake-by-wire system power-on piston forward-pushing zeroing method comprises the steps that a full-decoupling type brake-by-wire system is powered on, a servo cylinder piston is pushed forward by a stroke s1, and a corresponding pressure change value after the forward-pushing stroke s1 is obtained; whether the corresponding pressure change value after the forward pushing stroke s1 is larger than a threshold value p1 or not is judged, and if yes, after the preset stroke s2 is retreated, the step of forward pushing the servo cylinder piston by the stroke s1 is skipped to; if not, the piston of the servo cylinder is pushed forwards by the stroke s0, and the corresponding pressure change value after the forward pushing stroke s0 is obtained; whether the corresponding pressure change value after the forward pushing stroke s0 is larger than a threshold value p0 or not is judged, and if not, the step of pushing the piston of the servo cylinder forward by the stroke s0 is executed; if yes, the change making action is completed, and the piston of the servo cylinder retreats; wherein s0 < lt; s1lt; and s2. The piston of the servo cylinder can be electrified and changed in a forward pushing mode, and collision sound is avoided.

    本发明公开一种全解耦式线控制动系统上电活塞前推找零方法及系统,涉及车辆制动技术领域,包括:对全解耦式线控制动系统上电,将伺服缸活塞前推行程s1,并获取前推行程s1后对应的压力变化值;判断前推行程s1后对应的压力变化值是否大于阈值p1,若是,则回退预定行程s2后,跳转至将伺服缸活塞前推行程s1步骤;若否,则将伺服缸活塞前推行程s0,并获取前推行程s0后对应的压力变化值;判断前推行程s0后对应的压力变化值是否大于阈值p0,若否,则跳转至将伺服缸活塞前推行程s0步骤;若是,则表示找零动作完成,伺服缸活塞回退;其中,s0
