To prevent update of software of a vehicle control device from simultaneously occurring.SOLUTION: The present invention relates to a software update method for transmitting update data of software of a vehicle control device from an operation management server to a plurality of vehicles on which the vehicle control devices are mounted, via wireless communication and causing each vehicle control device to respectively execute update of the software. The operation management server divides the plurality of vehicles into a plurality of groups (step S103) and makes the timing in which the vehicle control device executes the update of the software different for each group (step S104 to step S109).SELECTED DRAWING: Figure 7
【課題】車両制御装置のソフトウェアの更新の同時発生を抑制する。【解決手段】車両制御装置が搭載された複数の車両に運行管理サーバから車両制御装置のソフトウェアの更新用データを無線通信により送信して各車両制御装置にソフトウェアの更新をそれぞれ実行させるソフトウェア更新方法であって、運行管理サーバは、複数の車両を複数のグループにグルーピングし(ステップS103)、車両制御装置がソフトウェアの更新を実行するタイミングをグループ毎にそれぞれ異ならせる(ステップS104~ステップS109)。【選択図】図7
