Abstract: Systems and methods for improving operation of a four wheel drive vehicle that includes automatic engine stopping and starting are presented. In one example, engagement of a driveline wheel mode is not permitted when an engine is automatically started so that a driveline wheel mode actuator may fully engage a driveline wheel mode when it is requested to do so.

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: 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 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 adjusting a steering torque threshold for automatically stopping and starting a vehicle engine. In one example, a method may include, while the engine is running, determining a first steering torque threshold for inhibiting stop-start of the engine based on a steering wheel angle, and, while the engine is auto-stopped, determining a second steering torque threshold for inhibiting the stop-start based on the steering wheel angle and whether a static stop-start event is present or a rolling stop-start event is present. In this way, a non-linear hysteresis is provided for automatically stopping and starting the engine.

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.

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 a vehicle that includes an engine that may be automatically stopped and started are described. In one example, inhibiting of automatic engine stopping and starting may be withdrawn in response to a change in driver vehicle settings or when a temperature of an engine is less than a threshold temperature.

Abstract: A hybrid electric vehicle includes a combustion engine, and an electric machine and storage battery coupled to one or more controller(s) configured to respond to various signals from a driver and vehicle components. In response, such controller(s) enable an automatic or auto ICE start stop capability that is managed for optimal HEV lifecycle operation, and fuel economy and efficiency. The controller(s) automatically start and stop the ICE in response to one or more of a torque demand signal, a vehicle speed signal, a steering torque power signal, and a brake signal. The controller(s) inhibit automatic stop of ICE responsive to the steering torque power exceeding a stop threshold, and in contrast initiate or enable automatic start responsive to the steering torque power exceeding a start threshold. The start threshold is calibrated and adjusted to exceed the stop threshold by a stability factor that is predetermined and/or adjusted by the controller(s).

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: 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 vehicle includes an engine and a controller programmed to autostop and autostart the engine. The controller is further programmed to, in response to receiving signals indicative of a driver exiting the vehicle while the engine is auto stopped, autostart the engine, and after expiration of a predetermined duration, autostop the engine and inhibit vehicle propulsion until an ignition cycle is initiated.
