Patent number: 9770974Abstract: A shutter mechanism is adapted to be provided to a grill opening in a vehicle body. Opening and closing operations of the shutter mechanism are controlled by an electronic control unit (ECU). The ECU determines whether a vehicle is in a traveling end state. If the vehicle is in the traveling end state, the ECU determines whether or not the shutter mechanism is in an open state. If the ECU determines that the open state of the shutter mechanism cannot be confirmed, the ECU controls the shutter mechanism to open the shutter mechanism.Type: GrantFiled: December 14, 2012Date of Patent: September 26, 2017Assignee: AISIN SEIKI KABUSHIKI KAISHAInventors: Yoshimasa Asano, Eri Yamamoto, Hitoshi Takayanagi
