Systems and methods for supplying electrical power between two electric energy storage devices are disclosed. In one example, an electric isolation switch is held open after engine starting until a voltage of a first electric energy storage device and a voltage of a second electric energy storage device are within a threshold voltage of at least one predetermined voltage level.

Vehicle electrical system and methods

Methods and systems are provided for controlling an engine idle-stop based on upcoming traffic and road conditions. In one example, a method may include receiving data including traffic information and road characteristics immediately ahead of a vehicle from one or more remote sources, and adjusting one or more vehicle thresholds based on the received data. A duration of a prospective engine idle-stop may be estimated based on the received data and an engine idle-stop may be initiated based on the duration of the prospective engine idle-stop and the adjusted one or more vehicle threshold.

Methods and systems for controlling engine idle-stop

A method for operating a vehicle that includes a DC/DC converter is described. In one example, the method includes adjusting an output voltage of the DC/DC converter after the DC/DC converter is used to crank an engine. The output voltage of the DC/DC converter may be adjusted responsive to a state of charge of an ultra-capacitor.

Methods and system for cranking an engine via output of a DC/DC converter

Systems and methods for operating an internal combustion engine are described. In one example, an engine's position is adjusted during engine stopping so that the engine may be less likely to stop at a crankshaft angle where rotating a fuel pump may increase engine cranking torque due to work performed by the fuel pump.

Methods and system for stopping and starting a vehicle

Systems and methods for operating an engine and a transmission to reduce a catalyst light off time are disclosed. In one example, clutches of a transmission are operated to provide a desired load to the engine so that engine combustion stability may be improved while supplying heat to a catalyst so that the catalyst light off time may be reduced.

System and method for increasing catalyst temperature

Systems and methods for operating a hybrid powertrain that includes an engine and a motor/generator are described. The systems and methods provide a way of prepositioning an engine to improve a range of driveline disconnect clutch transfer function adaptation. In one example, an engine is positioned at a location where its torque to turn exceeds a threshold torque.

Methods and system for adapting operation of a driveline disconnect clutch

Methods and systems are provided for controlling operation of an engine of a vehicle to supply power to a power box that in turn supplies power to loads external to the vehicle. In one example, a method comprises, via a controller, detecting that the vehicle is in a condition of reduced air exchange, and in response to a request to operate the engine to supply power to the power box, alerting the vehicle operator of the condition and discontinuing engine operation if a response to the alert is not received within a threshold duration. In this way, engine control strategy may account for the condition of reduced air exchange when the vehicle operator has acknowledged that the engine is operating under such conditions.

Systems and methods for controlling engine operation to support external electric loads

Methods and systems for improving operation of a vehicle driveline that includes an engine and an automatic transmission with a torque converter are presented. In one non-limiting example, the engine may be stopped while a vehicle in which the engine operates is rolling. A transmission coupled to the engine may be shifted as the vehicle rolls so that vehicle response may be improved if a driver requests an increase of engine torque.

System and method for performing an engine stop and start for a rolling vehicle

Systems and methods for restarting an engine are presented. In one example, an engine may be automatically stopped and started in response to thresholds that may be adjusted as a distance traveled by the vehicle increases. The thresholds may be adjusted responsive to useful life consumed of an engine starter that may participate in automatic engine starting and stopping.

Methods and systems for improving engine starter durability for a stop/start vehicle

A vehicle includes an engine, a transmission, a clutch, and a controller. The clutch is configured to couple the engine and transmission during engine starts. The controller is programmed to, in response to an actual engine start time being greater than an upper threshold time for an engine start event, alter an engine start torque apply schedule for the clutch such that the actual engine start time is less than the upper threshold time for a next engine start event. The controller may be further programmed to, in response to the actual engine start time being less than a lower threshold time for the engine start event, alter the engine start torque apply schedule for the clutch such that the actual engine start time is greater than the lower threshold time for the next engine start event.

Hybrid vehicle and method of controlling an engine disconnect clutch for engine start-up

An automotive vehicle includes an engine, an alternator or integrated starter generator, and at least one controller. The at least one controller reduces voltage output of the alternator or integrated starter generator prior to initiating an auto stop of the engine.

System and method for controlling alternator or integrated starter generator output voltage

Methods and systems for operating an engine including an external exhaust gas recirculation (EGR) system are presented. In one non-limiting example, output of a differential pressure sensor and output of an intake manifold pressure sensor are used as a basis for determining whether or not EGR system degradation is present while an engine is operating at conditions other than engine idle conditions.
