BRAKING CONTROL SYSTEM FOR A HYBRID OR ELECTRIC VEHICLE

A vehicle includes active grill shutters and a controller. The active grill shutters are configured to open to increase a drag on the vehicle and to close to decrease the drag on the vehicle. The controller is programmed to, in response to regenerative braking via an electric machine and an absence...

Beschreibung
Zusammenfassung:	A vehicle includes active grill shutters and a controller. The active grill shutters are configured to open to increase a drag on the vehicle and to close to decrease the drag on the vehicle. The controller is programmed to, in response to regenerative braking via an electric machine and an absence of friction braking, transition or maintain the active grill shutters to or in a closed position. The controller is further programmed to, in response to friction braking, transition or maintain the active grill shutters to or in the open position.
