ABSTRACT:
Aspects of the present invention are directed at allowing a vehicle to idle for a predetermined amount of time before shutdown. In accordance with one embodiment, a method is provided that accepts input from the vehicle operator to initiate a countdown to vehicle shutdown. When the input is received, a countdown is initiated that is regularly updated to reflect the passage of time. During the countdown, a vehicle ignition bus is maintained in an active state and a countdown value that reflects the time remaining before shutdown is presented on a graphical display. Then, in response to expiration of the countdown, the method allows the vehicle ignition bus to transition into an inactive state.
