PROBLEM TO BE SOLVED: To provide a communication system and a vehicle body-side communication device which can share a wireless communication device mounted on a vehicle in a remote locking system and a TPMS.SOLUTION: An ECU 1 switches the communication partner of a radio communication unit 12 according to the operation state of a shift lever 22. When the shift lever 22 is parking, the ECU 1 selects a wireless key 3 as a partner of the wireless communication of the wireless communication unit 12. When the shift lever 22 is other than parking, the ECU 1 switches a partner of the wireless communication of the wireless communication unit 12 alternately to the wireless key 3 or the sensor unit 6. The ECU 1 may, instead of the operating state of the shift lever 22, perform the switching according to the operating and/or release state of a parking brake 23 as well. Furthermore, the switching may be performed by adding a condition whether an IG switch 21 is on or not.

    【課題】遠隔ロックシステム及びTPMSにて車両に搭載された無線通信器を共用することができる通信システム及び車体側通信器を提供する。【解決手段】ECU1はシフトレバー22の操作状態に応じて無線通信部12の通信相手を切り替える。シフトレバー22がパーキングである場合、ECU1は無線通信部12の無線通信の相手に無線キー3を選択する。シフトレバー22がパーキング以外である場合、ECU1は無線通信部12の無線通信の相手を無線キー3又はセンサユニット6に交互に切り替える。なおECU1は、シフトレバー22の操作状態に代えて、パーキングブレーキ23の作動/解除状態に応じて切り替えを行ってもよい。またIGスイッチ21がオン状態であるか否かの条件をさらに加えて切り替えを行ってもよい。【選択図】図2
