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: Onboard need for data is determined based on a vehicle process requesting data. A request for the data is wirelessly communicated directly to other vehicles in local wireless communication. A price for the data is negotiated, and the data is received, responsive to sending an agreement to pay the negotiated price.

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.

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: 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: 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).

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 apparatus for controlling an electronic power assisted steering (EPAS) motor in response to detecting engine stall while restarting an auto stop-start engine are described. A controller is to ramp out current from an EPAS motor in response to detecting that an auto stop-start engine is stalled. The controller is also to invoke a stall recovery attempt at the auto stop-start engine in response to the ramp out of current. The controller is also to ramp in current to the EPAS motor in response to detecting that the auto stop-start engine has been successfully restarted based on the stall recovery attempt.
