The invention discloses a vehicle tire pressure protection control method, a vehicle tire pressure protection control system, vehicle-mounted equipment and a vehicle. According to the method, the difference between the current tire pressure and the target tire pressure of a plurality of wheels is obtained and compared; then, correspondingly determining the step number needing to be executed at least for adjusting the tire pressure of each wheel as the initial execution step number on the basis of the tire pressure allowable capacity variable quantity; furthermore, due to the fact that the tire pressure data of different wheels are different, on the premise that it is guaranteed that all the wheels can be adjusted to the target tire pressure at the same time, the product of the maximum value of the initial execution step number absolute value and the tire pressure change step length control factor is determined to be the target execution step number of the multiple wheels; and the single-step execution target tire pressure of the multiple wheels is determined according to the target execution step number, so that too fast tire pressure change is avoided.

    本申请公开了一种车辆胎压保护控制方法、系统、车载设备和车辆,该方法通过分别获取并比较多个车轮的当前胎压和目标胎压之间的差距,然后基于胎压允许能力变化量对应确定每个车轮的调整胎压最少需要执行的步数作为初始执行步数;进一步地,由于不同车轮的胎压数据不尽相同,为了在保证每个车轮都能同时地调整至目标胎压的前提下,确定初始执行步数绝对值的最大值与胎压变化步长控制因子的乘积为多个车轮的目标执行步数,并根据目标执行步数确定多个车轮的单步执行目标胎压,以避免胎压变化过快。
