The invention discloses a vehicle hydraulic valve duty ratio generation method, vehicle-mounted equipment and a vehicle, and the method comprises the steps: carrying out the limitation calculation of a duty ratio increase maximum value and a duty ratio decrease maximum value of a plurality of wheel brake hydraulic valves, and determining a duty ratio increase ratio multiple and a duty ratio decrease ratio multiple; determining a change limit of the duty cycle; then, according to the duty ratio increasing ratio multiple, the duty ratio decreasing ratio multiple, the duty ratio increasing speed control coefficient and the duty ratio decreasing speed control coefficient, the percentage adjusting optimization coefficient for adjusting all the wheel brake hydraulic valves is determined; and finally, according to the percentage adjustment optimization coefficient and the dynamic difference percentage, the execution dynamic percentage is determined, so that the dynamic duty ratio of the multiple wheel brake hydraulic valves is determined in real time, the duty ratio of the vehicle hydraulic valves is controlled to stably change to the expected duty ratio at high precision, and the stability of the vehicle is effectively guaranteed.

    本申请公开了一种车辆液压阀占空比生成方法、车载设备和车辆,该方法通过分别对多个车轮制动液压阀的占空比增加最大值和占空比减小最大值进行限制性计算,分别确定占空比增加比值倍数和占空比减小比值倍数,以确定占空比的变化限制;接下来,根据占空比增加比值倍数、占空比减小比值倍数、占空比增加快慢控制系数和占空比减小快慢控制系数,以确定调整各个车轮制动液压阀的百分比调整优化系数;最后,根据百分比调整优化系数和动态差异百分比,确定执行动态百分比,从而实现实时确定多个车轮制动液压阀的动态占空比,进而实现高精度控制车辆液压阀的占空比平稳变化至期望占空比,有效保证车辆的稳定性。
