The invention discloses an under-pressure alarm method and device for tires and a vehicle. The under-pressure alarm method for the tires comprises the following steps that after the vehicle is powered on, a tire pressure controller is awakened, and the speed of the vehicle is obtained; judging the relationship between the speed of the vehicle and a preset speed; when the speed is smaller than the preset speed, adopting a first threshold value as an undervoltage alarm threshold value; when the speed is greater than or equal to the preset speed for the first time, adopting a second threshold value as an undervoltage alarm threshold value; and when the tire pressure detected by the tire pressure controller is smaller than the under-pressure alarm threshold value, the tire pressure controller gives an alarm. Therefore, the alarm threshold value is adjusted by detecting and monitoring the speed of the tire when the vehicle runs and judging that the tire is in different stages, so that the alarm threshold value of the tire can be updated according to the running speed of the tire, and the under-pressure alarm accuracy of the tire is higher.

    本发明公开了一种车胎的欠压报警方法、欠压报警装置和车辆,车胎的欠压报警方法包括以下步骤:车辆上电后唤醒胎压控制器,并获取车辆的速度;判断车辆的速度与预设速度之间的关系:当速度小于预设速度时,采用第一阈值作为欠压报警阈值;当速度第一次大于等于预设速度后,采用第二阈值作为欠压报警阈值;当胎压控制器所检测到的胎压小于欠压报警阈值时,胎压控制器报警。这样,通过在车辆运行时对车胎的速度进行检测监控并判断其处于不同的阶段,以调整报警阈值,从而让车胎的报警阈值能够根据车胎的运行速度进行更新,以使车胎的欠压报警准确性更高。
