The invention provides a control method of a whole vehicle braking system. The control method comprises the following steps of: firstly, obtaining pressure increasing and reducing characteristics, then obtaining target braking torque according to state information of a vehicle through an established slip controller, and further obtaining target pressure of a braking air chamber; and controlling anair inlet valve and an air outlet valve of the brake chamber to work according to the pressurization characteristic curve graph or the decompression characteristic curve graph so as to realize pressure braking. The pressure increasing and decreasing characteristics obtained through the calibration method can bring convenience to regulation and control of the whole vehicle brake pressure, and therefore the regulation and control efficiency of the whole vehicle brake pressure regulation and control method is improved.

    本发明提供了一种整车制动系统的控制方法,先获取增减压特性,然后通过建立的滑移控制器根据车辆的状态信息得到目标制动扭矩,进而得到制动气室的目标压力,然后按照增压特性曲线图或者减压特性曲线图控制制动气室的进气阀和排气阀工作,进而实现压力制动。采用本发明的标定方法得到的增减压特性能够为整车制动压力的调控带来了便捷性,从而提高了整车制动压力调控方法的调控效率。
