To provide a grille shutter control apparatus capable of accurately determining a failure in a grille shutter even with communication falling into abnormality.SOLUTION: LA grille shutter control apparatus includes: a grille shutter ECU 14, connected to a LIN communication line 22, for controlling opening-closing of a grille shutter, and controlling the grille shutter so as to open it in a case where abnormality in communication is detected; and an engine ECU 12, connected to the LIN communication line 22, capable of detecting an opening degree of the grille shutter by communication, and determining that the grille shutter is failed in a case where an opening degree of the grille shutter is less than a predetermined threshold, with a water temperature higher than a predetermined threshold, when the abnormality in communication is detected.SELECTED DRAWING: Figure 2

    【課題】通信の異常が発生してもグリルシャッタの故障を正確に判定することが可能なグリルシャッタ制御装置の提供を目的とする。【解決手段】LIN通信線22に接続され、グリルシャッタの開閉を制御し、かつ通信の異常を検出した場合に、グリルシャッタを開放するようにグリルシャッタを制御するグリルシャッタECU14と、LIN通信線22に接続されて通信によりグリルシャッタの開度の検出が可能とされ、通信の異常の検出時に、通信の異常直前のグリルシャッタの開度が予め定めた閾値未満で、かつ水温が予め定めた閾値より高くなった場合に、グリルシャッタの故障と判定するエンジンECU12と、を備える。【選択図】図2
