The invention discloses a tire pressure monitoring module, a tire positioning system and a tire positioning method for a vehicle. The left and right positioning of the tire is realized by using the phase relation of the magnetic field intensities in two different directions measured by a magnetometer in the tire pressure monitoring module, and the front and back positioning of the tire is realized by using the size relation of the angle of arrival (AOA) of a first Bluetooth module in the tire pressure monitoring module relative to a multi-antenna Bluetooth host; therefore, high-precision automatic positioning of the vehicle tire is realized, and each tire pressure monitoring module can be mounted on any tire without any distinguishing, so that the mounting cost is reduced.
公开了一种用于车辆的胎压监测模块、轮胎定位系统及方法。通过利用胎压监测模块中磁力计所测量的两个不同方向的磁场强度的相位关系实现轮胎的左右定位,并利用胎压监测模块中第一蓝牙模块相对于多天线蓝牙主机的到达角(AOA)的大小关系实现轮胎的前后定位,从而实现高精度的车辆轮胎自动定位,且每个胎压监测模块可以安装在任意一个轮胎上,无需加以任何区分从而减少了安装成本。
