The invention provides a positioning device of tire pressure transmitters. The positioning device comprises a plurality of tire pressure transmitters, a plurality of wheel speed sensors and a signal receiver, wherein the plurality of tire pressure transmitters are respectively mounted on tires of an automobile, each tire pressure transmitter comprises a biaxial acceleration sensor and a signal transmitter, and the biaxial acceleration sensor is used for collecting biaxial acceleration data of the tire; the plurality of wheel speed sensors are used for collecting level signals of gears in an anti-lock braking system and sending the level signals to an electronic control unit of the anti-lock braking system, and the electronic control unit processes the received level signals to generate tooth number data and sends the tooth number data; and the signal receiver is mounted in the automobile, receives the biaxial acceleration data and the tooth number data, and determines the position of each tire pressure transmitter according to the phase difference relation of the received biaxial acceleration data and the convergence of the tooth number data at the moment corresponding to the received biaxial acceleration data.

    本发明提供一种轮胎压力发射机的定位装置,所述定位装置包括:多个轮胎压力发射机,分别安装在汽车的各轮胎上,每个轮胎压力发射机包括双轴加速度传感器和信号发射器,所述双轴加速度传感器用于采集轮胎的双轴加速度数据;多个轮速传感器,用于采集防抱死制动系统中齿轮的电平信号并将所述电平信号发送至防抱死制动系统的电子控制单元,所述电子控制单元处理接收到的所述电平信号生成齿数数据,并发送所述齿数数据;信号接收机,安装在汽车内,所述信号接收机接收所述双轴加速度数据和所述齿数数据,根据接收的所述双轴加速度数据的相位差关系和与所述接收的双轴加速度数据对应时刻的齿数数据的收敛性确定各轮胎压力发射机的位置。
