PROBLEM TO BE SOLVED: To make it possible to accurately register ID information on a transmitter attached to a spare wheel even if an antenna is not provided per wheel.SOLUTION: As spare wheel registration processing, it is determined whether G-OFF data is stored when a vehicle is in a state of traveling, and only ID information on a frame storing therein the G-OFF data during traveling is registered as a candidate ID of a spare wheel. From among the registered IDs, ID information on the spare tire is identified. Specifically, the number of times of receiving the frame storing therein the G-OFF data during traveling is measured, and it is determined whether a difference between the largest number of times of reception and the second largest number of times of reception is equal to or higher than a predetermined number (for example, 3). When the difference between the largest number of times of reception and the second largest number of times of reception is equal to or higher than the predetermined number, ID information on the frame received by the largest number of times of reception is registered as the ID information on the transmitter of the spare tire.SELECTED DRAWING: Figure 7

    【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の候補IDとして登録する。この登録IDの中から、スペア輪のID情報を特定する。具体的には、走行中にG−OFFデータが格納されたフレームの受信回数を計測し、最大受信数と2番目に多い受信数の差が所定数(例えば3)以上であるかを判定する。そして、最大受信数と2番目に多い受信数の差が所定数以上となった場合に、最大受信数のフレームのID情報がスペア輪の送信機のID情報であると登録する。【選択図】図7
