Description
ECU7L、7Rは、水温センサ52からの出力に基づいて、冷却水温を検出する(ステップS1)。尚、水温センサ52からの出力によらずに、公知の方法により冷却水温を推定してもよい。
図9は、実施例3の内燃機関の制御装置の冷却水の経路の説明図である。図9に示すように、実施例3の内燃機関の制御装置には、ラジエータ72を冷却するためのラジエータファン(以下、ファンと称する)73aが設けられている。ファン73aは、モータ73bによって作動する。モータ73bは、ECU7Lからの指令に応じて作動する。ファン73aにより、ラジエータ72での冷却水の放熱が促進される。ファン73aは、車両走行時においては停止している。走行時においては、走行風によりラジエータ72での冷却水の放熱が促進される。
ECU7L、7Rは、ステップS1〜S8まで実行すると、ECU7L、7Rは、ファン73aの作動期間を算出する(ステップS9a)。詳細には、ファン73aの作動期間とは、アイドル運転中におけるファン73aの作動期間である。図11は、ファン73aの作動期間を算出するためのマップである。図11のマップは、縦軸がファン73aの作動期間、横軸が第1カウンタ値T1を示している。図11のマップは、予めECU7L又はECU7RのROMに記憶されている。図11に示すように、第1カウンタ値T1が大きいほどファン73aの作動期間は長くなる。例えば、第1カウンタ値T1が、1000、2000、3000、4000の場合には、ファン73aの作動期間は、それぞれ、30、60、90、120(sec)に設定される。
