A tire attaching position detection system is provided which can suppress influence by an intensity of a reception signal from a tire. In the system (1), a sensor unit (4) is mounted on each tire (3), the sensor unit (4) has a geomagnetic sensor (12) for acquiring data on direction change of the tire (3), a distortion sensor (11) for acquiring data on number of rotations of the tire (3) and a transmitting part (15) for transmitting the direction change data and number of rotations data of the tire (3). A calculation part (23) of a user terminal (20) judges the attaching position of each tire (3) based on the direction change data and the number of rotations data of each tire (3) transmitted from the transmitting part (15).
本发明提供能够抑制来自轮胎侧的接收信号的强度产生的影响的轮胎安装位置检测系统。轮胎安装位置检测系统(1)中,在各轮胎(3)设置传感器单元(4)。传感器单元(4)具有:获取轮胎(3)的方向变化数据的地磁传感器(12)、获取轮胎(3)的转数数据的应变传感器(11)、发送轮胎(3)的上述方向变化数据及上述转数数据的发送部(15)。用户终端(20)的运算部(23)基于从发送部(15)发送的各轮胎(3)的上述方向变化数据及上述转数数据,判断各轮胎(3)的安装位置。
