Abstract: A stop/start vehicle includes an engine and a stop/start system that selectively prevents an auto stop or auto start of the engine in response to a detected vehicle proximity and direction of travel relative to an emergency vehicle. The stop/start system may be programmed to prevent an auto stop of the engine in response to a detected proximity to an emergency vehicle where the emergency vehicle is traveling in the same direction as the stop/start vehicle, or in response to a detected proximity to an emergency vehicle where the stop/start vehicle is located within an intersection. The stop start system may also be programmed to prevent an auto start of the engine in response to the engine being stopped, and further in response to a detected proximity to an emergency vehicle where the emergency vehicle is traveling in cross traffic relative to the stop/start vehicle.

Abstract: A stop/start system of a micro-hybrid vehicle may selectively initiate an engine auto start in response to a PRNDL gear lever/transmission being moved/shifted out of DRIVE after an engine auto stop and a determination that the vehicle is located, for example, in an intersection or railroad crossing prior to the PRNDL gear lever/transmission being moved/shifted into REVERSE.

Abstract: A stop/start vehicle includes an engine and a stop/start system that prevents an auto stop of the engine when a speed of the vehicle is approximately zero in response to the vehicle being located within a specified distance from a body of water or in response to the vehicle being located in a user identified geographic region.

Abstract: An engine of a stop/start vehicle, after the engine has been automatically stopped, may be commanded to automatically restart in response to detecting that the vehicle is in a turn lane based on traffic data in a vicinity of the vehicle such that the engine is automatically restarted before a brake pedal is released and a steering wheel is turned.

Abstract: A controller in a stop/start vehicle may anticipate a vehicle stop and engine shutdown event in response to detecting a vehicle approach to an intersection. The controller may disable a power steering system or otherwise prepare vehicle subsystems for shutdown prior to the anticipated shutdown event. The controller may also enable the power steering system in response to anticipating an automatic restart event.

Abstract: A stop/start system of a vehicle autostops and autostarts an engine and, in response to an identification of a drive cycle destination indicating that the vehicle will remain parked for at least a predefined period of time, prevents autostopping of the engine during the drive cycle to increase a state of charge of the battery above a nominal target state of charge.

Abstract: Vehicles equipped with an automatic start-stop system may include an interface for conveying inhibitors preventing an engine from auto-stopping in addition to the status of the automatic start-stop system. The system may identify one or more inhibitors actively preventing an auto-stop event from occurring and select at least one of the active inhibitors based on a priority scheme. The interface may communicate the at least one selected inhibitor to a driver using a display or a speaker, or both.
