The invention provides a hydraulic valve duty ratio method, device and equipment and a storage medium. The hydraulic control method comprises the following steps: determining a second duty ratio of each wheel brake hydraulic valve at the current moment based on a target duty ratio of each wheel brake hydraulic valve, a first duty ratio at the previous moment and a preset duty ratio change upper limit value; wherein the previous moment is a previous moment of the current moment; and under the condition that the second duty ratio does not reach the target duty ratio, the first duty ratio is adjusted to be the second duty ratio until the target duty ratio is reached, so that the duty ratio variable quantity can be controlled, the instantaneous duty ratio change of each wheel braking hydraulic valve is planned as a whole, and the braking efficiency of the vehicle is improved. And therefore, the instantaneous duty ratio of the hydraulic valve is controlled to stably change to the target duty ratio at high precision, so that the safety and the stability of the vehicle are ensured.

    本公开提供了一种液压阀占空比方法、装置、设备及存储介质。所述液压控制方法包括:基于各个车轮制动液压阀的目标占空比、上一时刻的第一占空比以及预设的占空比变化上限值,确定各个所述车轮制动液压阀当前时刻的第二占空比;其中,所述上一时刻为所述当前时刻的前一时刻;在所述第二占空比未达到所述目标占空比的情况下,将所述第一占空比调整为第二占空比,直至达到所述目标占空比,从而能够控制占空比变化量,统筹各个车轮制动液压阀的瞬时占空比变化,进而实现高精度控制液压阀的瞬时占空比平稳变化至目标占空比,以保证车辆的安全性与稳定性。
