以上説明したように、本実施形態によれば、無人車両2が走行コースデータに基づいて動作する場合において、制御装置30がウインカー操作装置31の操作データ及び管理装置3からのウインカーデータの両方を取得した場合、管理装置3から送信されたウインカーデータに基づいて、ウインカー20を制御する。これにより、制御装置30は、無人車両2のウインカー20を正しく作動させることができる。
図5は、コンピュータシステム1000の一例を示すブロック図である。上述の管理装置3、制御装置30、及び制御装置90のそれぞれは、コンピュータシステム1000を含む。コンピュータシステム1000は、CPU(Central Processing Unit)のようなプロセッサ1001と、ROM(Read Only Memory)のような不揮発性メモリ及びRAM(Random Access Memory)のような揮発性メモリを含むメインメモリ1002と、ストレージ1003と、入出力回路を含むインターフェース1004とを有する。上述の管理装置3の機能及び制御装置30の機能は、プログラムとしてストレージ1003に記憶されている。プロセッサ1001は、プログラムをストレージ1003から読み出してメインメモリ1002に展開し、プログラムに従って上述の処理を実行する。なお、プログラムは、ネットワークを介してコンピュータシステム1000に配信されてもよい。
上述の実施形態においては、無人車両2が自動モードと手動モードとに切換えられることとした。無人車両2は自動モードと手動モードとに切換えられなくてもよい。例えば、有人車両9を無人車両2として動作させる場合など、自動モードと手動モードとが存在しない無人車両2においても、無人車両2が走行コースデータに基づいて動作するときに、ウインカー操作装置31の操作データが取得された場合、ウインカー制御部30Dは、走行コースデータ取得部30Bにより取得されたウインカーデータに基づいて、ウインカー20を制御する。
