PROBLEM TO BE SOLVED: To exactly register ID information of a transmitter which is attached to a spare wheel even if having no antenna at each wheel.SOLUTION: It is determined whether or not G-OFF data are stored as spare wheel registration processing when a vehicle is in a traveling state, and only the ID information of a frame in which the G-OFF data are stored is registered as a candidate ID of a spare wheel 5e during traveling. Then, the ID information of the spare wheel 5e is specified out of the registration ID. Concretely, it is confirmed that a traveling history exists after transition to a registration mode, and only when the traveling history exists, the discrimination of an own vehicle and the other vehicle is performed. By this constitution, when there arises a state that the ID information of the transmitter 2 of the spare wheel 5e in the own vehicle is not registered to the candidate ID due to a reason such as the overflow of a memory capacity, the determination of the ID information of the spare wheel 5e is not performed.SELECTED DRAWING: Figure 8

    【課題】車輪毎にアンテナを備えなくても、スペア輪に取り付けられた送信機のID情報を的確に登録できるようにする。【解決手段】スペア輪登録処理として、車両状態が走行中の際にG−OFFデータが格納されているか否かを判定し、走行中にG−OFFデータが格納されたフレームのID情報のみをスペア輪5eの候補IDとして登録する。そして、この登録IDの中から、スペア輪5eのID情報を特定する。具体的には、登録モードに移行した後に走行履歴が有ることを確認し、走行履歴が有る場合にのみ、G−OFFデータが格納されたフレームの中から自車両のものと他車両のものとの判別を行う。これにより、メモリ容量が一杯等の理由によって自車両におけるスペア輪5eの送信機2のID情報が候補IDに登録されていない状態になったときに、スペア輪5eのID情報の判定が行われないようにできる。【選択図】図8
