VEHICLE CONTROL DEVICE

PROBLEM TO BE SOLVED: To minimize power consumption during a period until a time when a restart of an internal combustion engine is expected.SOLUTION: A control device 200 of a vehicle 100 comprises an energization control section which sets an energization pattern, minimizing power consumption during a period from a time when an internal combustion engine 1 is stopped until a time when the same is expected to be restarted, as a target energization pattern. The energization control section: calculates first electric energy to be consumed during the period required to maintain a temperature of a heat generator 35 at a plurality of maintenance temperatures for each maintenance temperature; calculates second electric energy to be consumed when increasing the temperature of the heat generator 35 from the maintenance temperatures to a target start-up temperature for each maintenance temperature; selects the maintenance temperature which minimizes a summation of the first electric energy and the second electric energy; and sets the energization pattern to increase the temperature of the heat generator 35 to the target start-up temperature after maintaining the temperature of the heat generator 35 at the selected maintenance temperature as the target energization pattern.SELECTED DRAWING: Figure 1 【課題】内燃機関の再始動が予想される時刻までの期間の電力消費量を最小限に抑える。【解決手段】車両１００の制御装置２００は、内燃機関１を停止させた時刻から内燃機関１の再始動が予想される時刻までの期間内における電力消費量が最少となる通電パターンを目標通電パターンとして設定する通電制御部を備える。通電制御部は、発熱体３５の温度を維持温度に維持する必要のある期間に消費される第１電力量を複数の維持温度ごとに算出し、発熱体３５の温度を維持温度から始動目標温度まで昇温させたときに消費される第２電力量を前記複数の維持温度ごとに算出し、第１電力量及び前記第２電力量の総和が最少となる維持温度を選択し、発熱体３５の温度をその選択した維持温度に維持した後、始動目標温度まで昇温させる通電パターンを目標通電パターンとして設定する。【選択図】図１
