Abstract
A tire pressure measuring system (TPMS) for transmitting pressure information from a tire to a vehicle body has a complicated structure when a plurality kinds of transmission data exist. A sensor unit receives a transmission electromagnetic field from a sensor control unit, and rectify-detects the received field. The counter of the sensor unit determines a rotation cycle of a tire, based on the signal obtained by the rectification detection, then switches the switch in conjunction with the rotation cycle, and sequentially sends the plurality of transmission data items for every tire rotation.
