Abstract: Methods and apparatus for controlling the ramp in of current to an electronic power assisted steering motor associated with an auto stop-start engine are described. A controller is to determine a moving average voltage of a vehicle battery. The controller is also to determine a voltage rate of change based on the moving average voltage. The controller is also to determine a moving average engine speed of an auto stop-start engine of the vehicle. The controller is also to ramp in current to an electronic power assisted steering motor of the vehicle based on the moving average voltage, the voltage rate of change, and the moving average engine speed.

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 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 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: An engine control system for a vehicle includes a controller that initiates a start of the engine in response to a state of charge (SOC) of a battery falling below an engine start threshold, initiates a stop of the engine in response to the SOC exceeding an engine stop threshold, and adjusts a value of the engine start threshold based on whether a load remote from the vehicle is drawing power from the battery.

Abstract: A vehicle includes electric brakes, an engine with a starter, a battery and a controller. The battery has a voltage and is configured to power the starter, the electric brakes, and the controller. The controller is configured to, in response to a speed of the vehicle falling within a specified range without propulsive demand and while the voltage is greater than an upper voltage that varies based on a charge needed to engage the brakes to stop the vehicle, stop the engine.

Abstract: Methods, apparatus, and computer storage media are disclosed for vehicle display based on vehicle speed. An example vehicle includes a speed sensor to measure a vehicle speed, a display controller to compare the vehicle speed to a threshold, and a display. The example display is to present, in response to the vehicle speed being less than the threshold, a first button at a button location. The example display is to present, in response to the vehicle speed being greater than or equal to the threshold, a second button at the button location.

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.

Abstract: A controller may be configured to respond to an engine start condition that occurs while an SOC of the battery is within a first predetermined range by running an engine until first occurrence of the start condition ceasing or the SOC achieving a target. The controller may further be configured to respond to an engine start condition that occurs while the SOC is within a second predetermined range less than the first by running the engine until the SOC achieves the target.

Abstract: A start-stop vehicle includes an engine configured to automatically stop and start during travel. The vehicle further includes a gear lever, a brake pedal, and a controller. The controller is programmed to restart the engine or inhibit restarting of the engine depending upon one or more sets of conditions of the vehicle. A method is also present for operating the vehicle based upon the one or more sets of conditions.

Abstract: Systems and methods for improving operation of a start/stop vehicle are presented. One method includes deactivating an engine start/stop mode in response to an electrical load of a trailer coupled to a vehicle. By deactivating the engine start/stop mode, it may be possible to conserve consumption of electrical energy and maintain state of battery charge to ensure the vehicle has sufficient electrical energy to restart the engine.

Abstract: A method for controlling vehicle powertrain operation includes activating all-wheel-drive or 4×4-operation provided one of an environmental condition, vehicle use condition and vehicle electrical condition exceeds a corresponding reference, deactivating fuel saving operation provided all-wheel-drive or 4×4-operation is activated, activating fuel saving operation provided none of said conditions indicates need for AWD/4×4-operation, deactivating all-wheel-drive or 4×4-operation provided fuel saving operation is activated.
