Abstract: Systems and methods for operating a hybrid powertrain or driveline that includes an engine and an integrated starter/generator are described. In one example, the integrated starter/generator may crank the engine via a pinion gear during a first engine start. The integrated starter/generator may crank the engine via a belt during a second engine start.

Abstract: A vehicle start/stop method includes inhibiting auto-stopping an engine responsive to an engine auto-stop command, activating a transmission gear shifter, and a rotational speed of a steering wheel being less than a threshold; auto-stopping the engine responsive to the engine auto-stop command, activating the gear shifter, and the rotational speed being greater than the threshold; auto-starting the engine responsive to activating the gear shifter and the rotational speed being less than the threshold while the engine is auto-stopped; and inhibiting auto-starting the engine responsive to activating the gear shifter and the rotational speed being greater than the threshold while the engine is auto-stopped.

Abstract: Systems and methods for operating an engine that may be automatically stopped and started responsive to vehicle operating conditions are disclosed. In one example, the engine may be automatically started after it has been automatically stopped in response to a driver applying a brake pedal while the vehicle's transmission is engaged in park. The engine may be started to increase transmission pump pressure prior to engaging a gear to reduce vehicle launch time.

Abstract: Systems and methods for improving operation of a vehicle that includes an engine that may be automatically stopped and started are presented. In one example, vehicle launch control parameters are adjusted responsive to a learned driving style. The approach may provide vehicle launches that are closer to driver expectations than vehicle launches that are based solely on accelerator pedal position.

Abstract: Systems and methods for operating an engine that may be automatically stopped and started responsive to vehicle operating conditions are disclosed. In one example, the engine may be automatically started after it has been automatically stopped in response to a driver applying a brake pedal while the vehicle's transmission is engaged in park. The engine may be started to increase transmission pump pressure prior to engaging a gear to reduce vehicle launch time.

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: Methods and systems are provided for enabling engine start/stop function in a vehicle with a detachable door. In one example, a method may include, adjusting an engine start/stop strategy responsive to a driver side door of the vehicle been detected to be absent. The adjustment to the start/stop strategy further may be modified based on a type of transmission system coupled to the vehicle.

Abstract: A system and method for operating an automatic start/stop system in a motor vehicle having an internal combustion engine, an automatic transmission and a torque converter with an impeller disconnect clutch is disclosed. A controller may implement an engine start/stop system by, at appropriate times, stopping engine by halting fuel and restarting engine when propulsion is needed. During an engine start/stop event, the engine is automatically shut down and the impeller clutch of the torque converter may be disengaged to decouple the impeller and the engine to provide for fuel and emissions savings.

Abstract: Systems and methods for improving operation of a vehicle are presented. In one example, a controller notifies a human vehicle driver before electric power consumers that are electrically coupled to the vehicle are deactivated. The controller may notify the human driver in response to a state of charge of a vehicle battery.

Abstract: A vehicle is provided. The vehicle may include an engine that is configured to auto-stop and auto-start. The system may also include a controller programmed to power an electrical actuator coupled to a steering mechanism to synchronize a drive angle of the vehicle and a steering wheel angle of the vehicle, in response to a parameter indicative of a likelihood of a wheel slip event exceeding a threshold and the steering-wheel angle being greater than a predetermined threshold.

Abstract: Methods and systems are provided for operation of a lifting mechanism coupled to a mobility service vehicle. In one example, a method may include, during an engine idle-stop, in response to a request for operation of a lifting mechanism used by mobility devices to access the vehicle, the transmission may be shifted to park, an electronic braking system may be enabled, and the engine may be restarted to provide power for operation of the lifting mechanism.

Abstract: A system and method for operating a vehicle equipped with an automatic stop and start system is disclosed. The vehicle includes an internal combustion engine, an automatic transmission and a fluid launch device with an impeller disconnect clutch. A controller may initiate an automatic stop or start of the engine under certain operating conditions. During an engine start/stop event, the engine is automatically shut down and the impeller clutch of the fluid launch device may be disengaged to decouple the engine and transmission from the driveline to provide for improved fuel economy and reduced emissions.

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.
