GRILLE SHUTTER CONTROL DEVICE

To provide a grille shutter control device which can inhibit accumulation of residual strain in an exhaust system component.SOLUTION: A control device 200 is mounted on a vehicle 100 including a grille shutter 47 which is disposed in an inflow passage 120, which guides travel window from a grille 130 to an interior of an engine compartment 110, and opens or closes the inflow passage 120. The control device 200 includes an opening/closing control part 220 which controls opening/closing of the grille shutter 47. The opening/closing control part 220 carries out warming facilitation control which keeps the grille shutter 47 in a closed state until warming of an engine 10 is completed. Further, the control device 200 includes a temperature acquisition part 210 which acquires a temperature of an exhaust manifold 15 which is an exhaust system component of the engine 10. The opening/closing control part 220 carries out temperature variation inhibition control, in which the grille shutter 47 is closed, when a temperature of the exhaust manifold 15 acquired by the temperature acquisition part 210 becomes a predetermined temperature or lower after completion of the warming facilitation control.SELECTED DRAWING: Figure 1 【課題】排気系部品に残留歪みが蓄積することを抑制できるグリルシャッタの制御装置を提供する。【解決手段】制御装置２００は、グリル１３０からエンジンコンパートメント１１０内へ走行風を導く流入路１２０内に配設されて流入路１２０を開閉するグリルシャッタ４７を備える車両１００に搭載され、グリルシャッタ４７の開閉を制御する開閉制御部２２０を備えている。開閉制御部２２０は、エンジン１０の暖気が完了するまでグリルシャッタ４７を閉じた状態に保持する暖気促進制御を実行する。また、制御装置２００は、エンジン１０の排気系部品であるエキゾーストマニホールド１５の温度を取得する温度取得部２１０を備えている。開閉制御部２２０が、暖気促進制御が終了したあと、温度取得部２１０によって取得されるエキゾーストマニホールド１５の温度が所定温度以下になるとグリルシャッタ４７を閉じる温度変化抑制制御を実行する。【選択図】図１
