Abstract: Methods and systems are provided for reducing corrosion of a charge air cooler and preventing engine misfire due to condensate formation. In response to a condensate forming region in a charge air cooler, a grille shutter system is adjusted, moving the condensate region to a different location in the charge air cooler. Grille shutter orientation may also be controlled in response to vehicle operating conditions and condensate-forming weather conditions.

Abstract: A failure determination device capable of performing failure determination for a shutter device of a vehicle with accuracy in a short time period. In an engine room of a vehicle, a condenser for a refrigeration cycle for an aircon is provided and at a front grille of the vehicle, a grille shutter device is provided for introducing ambient air for cooling the condenser into the engine room by opening a grille shutter. According to the failure determination device of the shutter device, a pressure of the refrigerant discharged from the condenser is detected as a refrigerant pressure. A failure of the grille shutter device is determined based on the refrigerant pressure, which changes at a large rate according to the opening/closing of the grille shutter, enabling failure determination with accuracy in a short time period.

Abstract: A compound shutter system includes a first shutter assembly having at least one louver operable to selectively open and close the first shutter assembly. The compound shutter system also includes a second shutter assembly disposed remotely from the first shutter assembly. The second shutter assembly includes at least one louver operable to selectively open and close the second shutter assembly. The compound shutter system additionally includes a drive element. The drive element operatively connects the first shutter assembly and the second shutter assembly and automatically coordinates operation of the first and second shutter assemblies. A vehicle employing the compound shutter system is also disclosed.
