To enable a period to update control program of a plurality of control devices mounted on an electric vehicle to be secured while curbing an increase in power consumption when updating the control program.SOLUTION: When an OTA request is made (Yes in S100), an update ECU executes processes including: a step (S102) to acquire an ECU to be a subject of OTA; a step (S108) to request the ECU to be the subject of OTA to execute an update process when the ECU to be the subject of the OTA is the ECU to be operated while an electric vehicle is traveling (Yes in S104) and the electric vehicle is performing external charging (Yes in S106); and a step (S114) to request the ECU to be the subject of the OTA to execute the update process when the ECU to be the subject of the OTA is the ECU to be operated while the electric vehicle is performing the external charging (No in S104 and Yes in S110) and the electric vehicle is traveling (Yes in S112).SELECTED DRAWING: Figure 3

    【課題】電動車両に搭載された複数の制御装置の制御プログラムの更新時の消費電力の増加を抑制しつつ、更新する期間の確保を可能とする。【解決手段】更新ECUは、OTA要求があると(S100にてYES)、OTA対象のECUを取得するステップ(S102)と、対象ECUが走行中に動作するECUである場合(S104にてYES)、外部充電中であるときに(S106にてYES)、対象ECUに更新処理の実行を要求するステップ(S108)と、対象ECUが外部充電中に動作するECUである場合(S104にてNOかつS110にてYES)、電動車両が走行中であるときに(S112にてYES)、対象ECUに更新処理の実行を要求するステップ(S114)とを含む、処理を実行する。【選択図】図3
