PROBLEM TO BE SOLVED: To allow a continuous operation of an ETC system even if a foreign substance is attached to a first vehicle detector.SOLUTION: The lane controller according to an embodiment includes an antenna, a first vehicle detector, a second vehicle detector, and a controller. The controller starts emission of a radio wave from an antenna and enables a radio communication with a vehicle if the first vehicle detector detects an entrance of a vehicle into a communication range, and executes regular state processing of stopping the emission of the radio wave from the antenna if the second vehicle detector detects an exit of a vehicle out of the communication range. If the first vehicle detector detects an entrance of a vehicle into the communication range when the second vehicle detector detects an exit of a vehicle out of the communication range, the controller stops the regular state processing, and executes abnormal state processing of allowing a radio communication with a vehicle by emitting a radio wave from the antenna until the second vehicle detector detects an exit of a vehicle out of the communication range again.SELECTED DRAWING: Figure 2

    【課題】第1車両検知器に異物が付着しても、ETCシステムの運用を継続できる。【解決手段】実施形態の車線制御装置は、アンテナと、第1車両検知器と、第2車両検知器と、制御部と、を備える。制御部は、第1車両検知器によって通信範囲内への車両の進入が検知された場合に、アンテナからの電波の照射を開始して車両と無線通信可能とし、かつ第2車両検知器によって前記通信範囲内からの車両の退出が検知された場合に、アンテナからの電波の照射を停止する通常状態処理を実行し、第2車両検知器によって通信範囲内からの車両の退出が検知された際に、第1車両検知器によって通信範囲内への車両の進入が検知された場合、通常状態処理を中止し、かつ第2車両検知器によって、再び、通信範囲内からの車両の退出が検知されるまで、アンテナから電波を照射して車両と無線通信可能とする異常状態処理を実行する。【選択図】図2
