Zusammenfassung:	PROBLEM TO BE SOLVED: To suppress temperature rise of a smoothing capacitor of an inverter when a hybrid vehicle is in an engine stop state.SOLUTION: A cooling system control device controls a cooling system of a hybrid vehicle 100 including an engine 1, a driving motor 2, a radiator fan 11 driven by battery power, engine cooling piping 8, and a water pump 10 for circulating engine cooling water between a radiator 9 and the engine 1. The cooling system control device includes a fan control device 6 which continues to rotate the radiator fan 11 when an engine room internal temperature is higher than a prescribed engine room internal temperature in an engine automatic stop state.SELECTED DRAWING: Figure 1 【課題】ハイブリッド車両がエンジン停止状態にある場合の、インバータの平滑コンデンサの温度上昇を抑制する。【解決手段】冷却システム制御装置は、エンジン１及び駆動モータ２と、バッテリ電力によって駆動されるラジエータファン１１と、エンジン冷却配管８と、ラジエータ９とエンジン１との間でエンジン冷却水を循環させるウォータポンプ１０と、を有するハイブリッド車両１００の冷却システムを制御する。この冷却システム制御装置は、エンジン自動停止状態の場合にエンジンルーム内温度が所定エンジンルーム内温度より高いときには、ラジエータファン１１を回転させ続けるファン制御装置６を備える。【選択図】図１
