EXHAUST HEAT RECOVERY CONTROL SYSTEM

To provide an exhaust heat recovery control system in which a coolant and transmission oil can be independently heated.SOLUTION: An exhaust heat recovery control system includes: an internal combustion engine 1; a first coolant passage 11 through which a coolant for cooling the internal combustion engine 1 can flow; an exhaust heat recovery part 2 which is provided in the first coolant passage 11, and can collect heat from exhaust gas of the internal combustion engine 1 into the coolant; a second coolant passage 12 which is branched at a downstream side of the first coolant passage 11 to which the exhaust heat recovery part 2 is provided; a transmission oil warmer 3 which is provided in the second coolant passage 12, and can heat transmission oil by the coolant in which the heat is collected by the exhaust heat recovery part 2; and a first valve 21 which can control the flow of the coolant in the second coolant passage 12.SELECTED DRAWING: Figure 1 【課題】冷却液とトランスミッションオイルとを独立して加熱することができる排熱回収制御システムを提供する。【解決手段】内燃機関１と、内燃機関１を冷却する冷却液が流通可能な第１冷却液流路１１と、第１冷却液流路１１に設けられ、内燃機関１の排ガスから冷却液に熱を回収可能な排熱回収器２と、排熱回収器２が設けられた第１冷却液流路１１の下流側において分岐した第２冷却液流路１２と、第２冷却液流路１２に設けられ、排熱回収器２で熱を回収した冷却液によってトランスミッションオイルを加熱可能なトランスミッションオイルウォーマ３と、第２冷却液流路１２における冷却液の流れを制御可能な第１バルブ２１とを備える排熱回収制御システムとする。【選択図】図１
