Claims (1)
- 車両に搭載される水冷式内燃機関の冷却水系統において、
現在の冷却水温、外気温及び車両の駆動系の変速機に用いられるフルードの温度に応じて、車室内の空気との間で熱交換を行うヒータコア及び前記フルードとの間で熱交換を行う熱交換器に冷却水を流通させるか否かを制御するものであり、
前記ヒータコアを流通する冷却水が流れる流路と、この流路とは異なり前記熱交換器を流通する冷却水が流れる流路とにそれぞれ、現在の冷却水の温度によらず任意に開閉操作可能なバルブが個別に設置され、前者の流路の開閉と後者の流路の開閉とを独立して制御でき、
外気温がある値β未満の低温でかつ冷却水温がある値α以上に高い場合、または、外気温が値β未満の低温でかつフルード温がある値γを超えて高温化している場合には、前記各バルブを制御して内燃機関からの冷却水を前記ヒータコア及び前記熱交換器に流入させ、
外気温が値β未満の低温でかつ冷却水温が値α未満の場合、または、外気温が値β未満の低温でかつフルード温が値γを超えない場合には、前記各バルブを制御して内燃機関からの冷却水を前記ヒータコアに流入させ前記熱交換器には流入させない制御装置。
