Abstract: The criteria used to determine whether to initiate an auto stop of an engine may be altered based on a number of previous auto stops of the engine, a total auto stop off time of the engine, or a total throughput of a battery. Altering the criteria may influence a frequency with which the engine is auto stopped.

Abstract: A system and method for controlling a start-stop system for an engine in a vehicle includes automatically stopping the engine with a transmission gear lever of the vehicle in DRIVE. The engine is automatically restarted when the vehicle is shifted out of DRIVE and at least one condition is met. The at least one condition includes a final position of the gear lever. Automatic restarting of the engine is suppressed when the vehicle is shifted out of DRIVE and at least one other condition is met; the at least one other condition also including a final position of the gear lever.

Abstract: A system and method for controlling a start-stop system for an engine in a vehicle includes automatically stopping the engine when the vehicle is in NEUTRAL and automatically restarting the engine when the vehicle is shifted out of NEUTRAL and at least one condition is met. The at least one condition may include the direction of movement of a transmission gear lever. Automatic restarting of the engine is suppressed when the vehicle is shifted out of NEUTRAL and at least one other condition is met. The at least one other condition may also include the direction of movement of the transmission gear lever.

Abstract: A vehicle includes an engine and a stop/start system that selectively auto stops and auto starts the engine, detects an auto stop inhibit condition that prevents the engine from being auto stopped, and in response, generates output based on the auto stop inhibit condition if the auto stop inhibit condition falls within a predetermined class of auto stop inhibit conditions. The vehicle also includes an interface that displays or plays the output to inform a driver of the vehicle about the detected auto stop inhibit condition.
