Abstract:
1. A grille control mechanism for a vehicle, comprising: a movable member, a position of which is switchable between an opened position for allowing an ambient air to flow into a radiator provided at the vehicle and a closed position for inhibiting or restricting the ambient air from flowing into the radiator; an electric motor actuating the movable member; and a control means controlling an electric current to be supplied to the electric motor in order to execute an opening operation or a closing operation of the movable member in a case where an opening operation condition for controlling the movable member to be at the opened position or a closing operation condition for controlling the movable member to be at the closed position is satisfied based on a signal outputted from a sensor, wherein the control means determines whether or not a maintained operation condition, which is one of the opening operation condition and the closing operation condition, is maintained for a predetermined time, the control means, in a case where the control means determines that the maintained operation condition is maintained for the predetermined time, controls the electric current to be supplied in order to execute one of the opening operation and the closing operation corresponding to the maintained operation condition, and the control means continuously controls the electric current to be supplied intermittently to the electric motor according to the maintained operation condition, until the control means determines that the maintained operation condition changes to the other one of the opening operation condition and the closing operation condition based on the signal outputted from the sensor.
