The invention discloses a front and rear wheel positioning method and a tire pressure monitoring device and system.The front and rear wheel positioning method comprises the steps that in the wheel rotating process, the acceleration of a TPMS device is sampled, and whether the TPMS device reaches a preset phase point or not is judged according to the sampled acceleration value; the acceleration is tangential acceleration and/or centrifugal acceleration; the TPMS device is mounted on the wheels; when the TPMS device reaches the preset phase point every time, transmitting a radio frequency signal once through a radio frequency transmitter on the TPMS device, and receiving the radio frequency signal through a radio frequency receiver; and determining whether the wheel is a front wheel or a rear wheel based on the change condition of the signal intensity information of the received radio frequency signal. According to the scheme, the front and rear wheel positioning success rate can be improved.

    本申请公开了一种前后轮定位方法、轮胎压力监测装置及系统,其中,该前后轮定位方法包括:在车轮转动过程中,对TPMS装置的加速度进行采样,并根据采样的加速度值判断所述TPMS装置是否达到预设相位点;所述加速度为切向加速度和/或离心加速度;所述TPMS装置安装在所述车轮上;在每次所述TPMS装置达到所述预设相位点时,通过TPMS装置上的射频发射器发射一次射频信号,并通过射频接收器接收所述射频信号;基于接收到的所述射频信号的信号强度信息的变化情况来确定所述车轮为前轮或后轮。上述方案,能够提高前后轮定位的成功率。
