PROBLEM TO BE SOLVED: To improve registration accuracy of sensor ID of an own vehicle.SOLUTION: A wheel ECU temporarily registers sensor ID of a radio signal including pressure sudden change information indicating that tire air pressure suddenly changes of radio signals received when the tire air pressure of an own vehicle is removed at a prescribed speed in step S20. The wheel ECU compares sensor ID of a radio signal received during traveling of the vehicle after the tire air pressure of the own vehicle is returned to a normal state with sensor ID temporarily registered in ID temporary registration processing during stopping and formally registers the matched sensor ID as sensor ID of a sensor unit of the own vehicle in step S30.SELECTED DRAWING: Figure 3 |
