Zusammenfassung:PROBLEM TO BE SOLVED: To avoid a situation that a start of an engine is failed when the start of the engine is tried by using one starter which is left for a long period of time, in a vehicle having two starters.SOLUTION: When a start requirement of a vehicle is detected, a state determination part 221 determines whether or not there is satisfied a prescribed condition that a water temperature detected by a water temperature sensor 204 is higher than a prescribed reference temperature To which is high in a possibility to be established at the start requirement of the vehicle. When the state determination part 221 determines that the water temperature detected by the water temperature sensor 204 is higher than the reference water temperature To, a start control part 222 starts an engine 1 by a B-ISG 2, and performs processing for confirming whether or not a gear drive-type starter 7 is normal.SELECTED DRAWING: Figure 2 【課題】2つの始動装置を備える車両において、一方の始動装置が長期間放置され、当該始動装置でエンジンの始動を試みた場合に、エンジンの始動に失敗する事態を回避する。【解決手段】状態判定部221は、車両の始動要求を検知した場合、水温センサ204が検知した水温が、所定の基準温度Toより大きいという、車両の始動要求時に成立する可能性が高い所定条件を満たすか否かを判定する。始動制御部222は、状態判定部221により、水温センサ204により検知された水温が基準温度Toよりも大きいと判定された場合、B−ISG2でエンジン1を始動させると共に、ギヤ駆動式スタータ7が正常であるか否かを確認する処理を実行する。【選択図】図2
