PROBLEM TO BE SOLVED: To provide a device capable of suppressing temperature rise of an engine room in grille shutter closing failure.SOLUTION: An engine room temperature rise suppression device 100 is configured to suppress temperature rise of an engine room in a vehicle that introduces outside air through a grille shutter to be opened/closed according to an opening/closing command, and includes: a closing failure detection unit 30B configured to detect grille shutter closing failure that the grille shutter is still closed although an opening command is issued; and a transmission ratio control unit 30E configured to, when the closing failure detection units 30B detects the grille shutter closing failure, control a transmission ratio of a continuously variable transmission so that an upper limit value of an engine speed is restricted compared to a case where the grille shutter closing failure is not detected.SELECTED DRAWING: Figure 3
【課題】グリルシャッタ閉じ故障時のエンジンルームの温度上昇を抑制する装置を提供する。【解決手段】エンジンルーム温度上昇抑制装置100は、開閉指令に応じて開閉するグリルシャッタを介して外気を導入する車両におけるエンジンルームの温度上昇を抑制する装置であり、開指令に拘らずグリルシャッタが閉じられたままのグリルシャッタ閉じ故障を検出する閉じ故障検出部30Bと、閉じ故障検出部30Bによりグリルシャッタ閉じ故障が検出されると、グリルシャッタ閉じ故障が検出されないときよりも、エンジン回転数の上限値が制限されるように無段変速機の変速比を制御する変速比制御部30Eとを備える。【選択図】図3
