The invention relates to a tire leakage monitoring method and system, and the method comprises the steps: when a vehicle is started, determining a monitoring date window; a monitoring date tire pressure value corresponding to each monitoring date is determined within the range of the monitoring date window; determining the maximum monitoring day tire pressure value in the range of the monitoring date window as the maximum date value; determining a difference value between the maximum date value and the current day tire pressure value as a date difference value; and comparing the date difference value with a slow air leakage threshold value, and determining that the tire has slow air leakage under the condition that the date difference value is greater than the slow air leakage threshold value. According to the invention, a driver and passengers can be reminded earlier and more accurately if the air leakage state is abnormal before the tire is under-pressure.

    本申请涉及轮胎漏气监测方法和系统,所述轮胎漏气监测方法包括:每当车辆启动时,执行以下步骤:确定监测日期窗口;在所述监测日期窗口的范围内确定对应于每个监测日期的监测日胎压值;确定所述监测日期窗口的范围内最大的监测日胎压值为最大日期值;确定所述最大日期值与所述当日胎压值之间的差值为日期差值;以及比较所述日期差值与慢漏气阈值之间的大小,并且在所述日期差值大于所述慢漏气阈值的情况下,确定所述轮胎发生慢漏气。本申请可以在轮胎发生欠压之前,若出现漏气状态异常的情况,更早更准确地提醒驾乘人员。
