The invention discloses a hydraulic control method, device and equipment for a multi-wheel automobile brake system and a storage medium. The method comprises the steps that according to the tracking hydraulic target variable quantity of each wheel brake cylinder and the tracking hydraulic theoretical change boundary value of each wheel brake cylinder in a task period, the tracking hydraulic target variable quantity of each wheel brake cylinder is calculated; and the tracking hydraulic execution variable quantity of each wheel brake cylinder and the transient tracking hydraulic pressure at the current moment are calculated and determined, and the time required for changing the transient tracking hydraulic pressure of each wheel brake cylinder to the driving intention hydraulic pressure of each wheel brake cylinder is controlled to be consistent. The tracking hydraulic execution variable quantity of each wheel brake cylinder is smaller than or equal to the tracking hydraulic theoretical change boundary value of each wheel brake cylinder in the task cycle, so that the hydraulic change of each hydraulic cylinder is effectively prevented from exceeding the allowable working capacity; the time from transient tracking hydraulic changes of the wheel brake cylinders to driving intention hydraulic changes of the wheel brake cylinders can be controlled to be equal, and the situation that the transient tracking hydraulic changes of the wheel brake cylinders are not coordinated with one another is avoided.

    本发明公开了一种多轮汽车制动系统液压控制方法、装置、设备及存储介质,其中,方法包括根据各轮制动缸的跟踪液压目标变化量和任务周期内各轮制动缸的跟踪液压理论变化边界值,计算确定各轮制动缸的跟踪液压执行变化量和当前时刻的瞬态跟踪液压,控制实现各轮制动缸的瞬态跟踪液压变化至各轮制动缸的驾驶意图液压所需时间一致。本发明中各轮制动缸的跟踪液压执行变化量小于或等于其根据任务周期内各轮制动缸的跟踪液压理论变化边界值,有效避免了各液压缸的液压变化超出允许的工作能力;本发明可控制各轮制动缸的瞬态跟踪液压变化至各轮制动缸驾驶意图液压的时间相等,避免了各轮制动缸的瞬时跟踪液压变化相互之间不协调。
