Description
また、車両用プログラムの更新を実行する要求が有る場合には、車両用蓄電装置の残電力量が更新時必要残電力量未満であると判定された場合に、車両用蓄電装置の残電力量の低下を抑制する制御が実行されるので、車両用プログラムの更新の実行中に車両用蓄電装置の残電力量が不足することが適切に抑制される。
また、更新用プログラムにおけるデータ更新量に基づいて更新時消費電力量の推定値が算出されると共に、通常時必要残電力量に更新時消費電力量の推定値を加算した値が更新時必要残電力量として算出されるので、車両用プログラムの更新の実行中に車両用蓄電装置の残電力量が不足することが一層適切に抑制される。
