Lincoln Aviator: Front End Body Panels / Description and Operation - Active Grille Shutter - Overview
Overview
The
AGS (Active Grille Shutter) system is primarily used to improve fuel
economy by reducing aerodynamic drag while the vehicle in moving. It is
also used to shorten engine warm-up time, which increases engine
efficiency and provides faster heat delivery to the vehicle cabin. The
active grille shutter actuator receives position commands from the PCM via the LIN.
Each
AGS (Active Grille Shutter) system assembly is comprised of a set of
vanes, linkage hardware and an active grille shutter actuator (motor).
The
active grille shutter system carries out a self-calibration sequence
whenever the engine is started, fully opening and closing the shutters
before being positioned to the desired opening position as requested by
the PCM.
AGS (Active Grille Shutter) will also be active in HEV, during plug-in charging to provide airflow for HEV cabin climate conditioning and component cooling when the vehicle is stationary. In HEV vehicles, the desired AGS (Active Grill Shutter) position request is transmitted by the SOBDMC and received by the PCM.
Regardless of the hardware modules present in a vehicle, the PCM will send the appropriate control signal to the Active Grill Motor.
A
vehicle may be fitted with a single or a dual AGS (Active Grill
Shutter) hardware system, depending on vehicle type, front end packaging
and underhood / powertrain hardware components installed. Each system
uses a separate AGS (Active Grill Shutter) motor that can be controlled
independently, depending on system requirements. It also provides its
own diagnostic status to the PCM for monitoring.
