The invention discloses a hydraulic valve control method and device and a vehicle hydraulic brake control system. The hydraulic valve control method comprises the steps that a target pressure value of a current request and an actual output pressure value currently corresponding to a hydraulic valve are obtained; according to the target pressure value and the actual output pressure value, a preset closed-loop control algorithm model is adopted for calculation to obtain a control output value; and based on the control output value, the duty ratio of a driving signal output by the driving circuit to the hydraulic valve is adjusted, and the adjusted duty ratio is equal to the duty ratio corresponding to the control output value. By the adoption of the hydraulic valve, the output pressure corresponding to the adjusted hydraulic valve can be accurately controlled.

    本申请公开了一种液压阀控制方法、控制装置和车辆液压制动控制系统。液压阀控制方法,包括:获取当前请求的目标压力值以及液压阀当前对应的实际输出压力值;根据目标压力值和实际输出压力值,采用预设的闭环控制算法模型计算得到控制输出值;基于控制输出值,调节阀驱动电路输出至液压阀的驱动信号的占空比,调节后的占空比等于控制输出值对应的占空比。采用本申请,可以精确控制调节后液压阀对应的输出压力的大小。
