Systems and methods for operating an engine of a vehicle that may be automatically stopped and started are disclosed. In one example, a speed at which a vehicle system induced automatic engine stop inhibit request is cleared may be adjusted to permit automatic engine stopping during a wide variety of driving conditions so that fuel may be conserved and the possibility of disturbing vehicle occupants may be reduced.

Methods and system for operating an engine

A vehicle includes an engine and a controller. The controller starts the engine in response to a brake status before and during a change in vehicle operating mode achieving predetermined states, and expiration of a timer initiated upon completion of the change and having a duration based upon a learned mean mode-specific shift time window. The change is initiated in response to a request to change vehicle operating mode while the engine is off.

Engine stop and start debounce timer for vehicles

A method of controlling power to a vehicle accessory gradually shuts down power to the vehicle accessory and gradually restores power to the vehicle accessory. After a request for an auto-shutdown of an internal combustion engine of a vehicle is detected, power to the vehicle accessory is reduced on a predetermined schedule responsive to such detection. The occurrence of a restart of the internal combustion engine of a vehicle is determined, and power supplied to the vehicle accessory is increased on a predetermined schedule responsive to the restart.
