Abstract: A vehicle includes an engine operable in an auto stop-start (SS) mode. The engine is adapted to auto stop and auto start in the SS mode. The vehicle further includes a transmission operable in an idle load reduction (ILR) mode. In the ILR mode, engagement of a forward clutch is disposed in an alternate first gear state. A controller is operably connected to the engine and the transmission. The controller is programmed to command the engine to operate in the SS mode when a speed of the vehicle is below a predetermined threshold unless one or more SS inhibit conditions are present. The controller is further programmed to, when one or more SS inhibit conditions are present, inhibit operation of the engine in the SS mode and to command the transmission to operate in the ILR mode unless one or more ILR inhibit conditions are present.

Abstract: A hybrid electric vehicle (HEV) that includes an internal combustion engine and a climate control system (CCS) coupled to controllers configured to auto start-stop the engine when the HEV decelerates to an engine-stop threshold speed. The controllers are also configured to adjust a climate-fan-speed by a predetermined initial-factor, and at subsequent timed-intervals with a speed-factor that is adjusted from the initial-factor at each timed-interval, such that engine restart is inhibited by perceptually small speed adjustments and perceptually slow timed-interval cabin cooling adjustments. Such gradual adjustments are tuned to increase passenger perceptions of continuing cabin comfort, which reduce the likelihood that a passenger may adjust the CCS to require engine restart, and to increase auto stop-start fuel economy.

Abstract: A vehicle is provided. The vehicle may include a controller that, in response to a number of engine stops that occur within a first predefined time period exceeding a user defined threshold value, inhibit further engine auto stops. The vehicle may include a controller that, in response to a number of engine stops that occur within a first predefined distance travelled by the vehicle exceeding a user defined threshold value, inhibit further engine auto stops.

Abstract: A vehicle includes an engine, automatic transmission, and a controller. The engine is configured to auto-start and auto-stop. The automatic transmission has a shift-by-wire gear selector. The controller is programmed to, in response to shifting the gear selector to a neutral position while the engine is running, command the engine to auto-stop.

Abstract: A method according to an exemplary aspect of the present discourse includes, among other things, controlling a vehicle by pressurizing a transmission pump in response to an anticipated shift change trigger. The anticipated shift change trigger may include touching a shift device of the vehicle, or detecting that a vehicle occupant is in proximity to the shift device of the vehicle.
