Abstract: Systems and methods for operating a vehicle that includes an engine that may be automatically stopped and started are described. In one example, an engine may be automatically stopped in response to a brake booster vacuum threshold level that is adjusted responsive to vehicle speed so that opportunities to automatically stop an engine may be increased, thereby conserving fuel.

Abstract: Methods and systems are provided for indicating whether a wastegate positioned in a vehicle exhaust system is stuck in a closed or open configuration. In one example, a method comprises activating an electric air compressor positioned in an intake of the engine and obtaining a first baseline air flow and a second baseline air flow in the exhaust system, and in response to an indication that the wastegate is potentially stuck open or closed, obtaining a test air flow measurement via activating the electric air compressor and comparing the test air flow in the exhaust system to the first and/or the second baseline air flow. In this way, the wastegate may be diagnosed under conditions of limited engine operation, such as that which may occur in hybrid electric vehicles.

Abstract: A method for an enhanced vehicle monitoring system that utilizes cameras and other sensors to determine the state of the interior and/or exterior of a vehicle is provided. The method comprises detecting that a driver has exited a vehicle. The method further comprises monitoring a state of the vehicle. The method further comprises determining based, at least in part, on the monitoring, if an object has been left in the vehicle unintentionally or if the vehicle has been left running unattended. The method further comprises, upon determining that the object has been left in the vehicle or the vehicle has been left running unattended, sending a notification to the driver.

Abstract: Systems and methods for injecting fuel to an engine in response to a fuel injection delay are presented. The method includes determining fuel delay in a fuel injected engine with cylinders that may be deactivated. In one example, the fuel injection delay is determined via a cylinder firing schedule array when the cylinder firing schedule array is available. The fuel injection delay is determined via a weighted average of a fuel injection delay of a present engine cycle and a fuel injection delay of a past engine cycle when the cylinder firing schedule array is not available.

Abstract: Methods and systems are provided for increasing an efficiency of a purging operation of a fuel vapor storage canister of a vehicle, the fuel vapor storage canister configured to capture and store fuel vapors stemming from a fuel tank of the vehicle. As one example, a method comprises reactivating one or more cylinders of an engine during a purging operation, in response to an indication that the purging of stored fuel vapors from the fuel vapor storage canister is compromised as a result of fuel vaporization stemming from the fuel tank. In this way, the canister may be effectively cleaned even under high fuel vaporization circumstances, which may improve fuel economy and may reduce release of undesired evaporative emissions to atmosphere.

Abstract: An exhaust purification system includes: an NOx reduction type catalyst; an MAF sensor; an SOx purge control unit that uses an air system control having an intake air amount feedback-controlled based on a target intake air amount and an injection system control for a target injection increase amount set based on the target intake air amount, and a fuel injection amount feedback-controlled based on the target injection increase amount; an SOx purge prohibition processing unit that prohibits an SOx purge control; and a warming mode control unit that open-loop controls an air system when the SOx purge control is prohibited, controls the fuel injection amount, and maintains the exhaust gas at a temperature. The SOx purge control unit executes the injection system control by switching the target intake air amount into an actual intake air amount when starting the SOx purge control after a warming mode control is ended.

Abstract: A method of controlling oxygen purge of a three-way catalyst may include: performing a fuel cut-off; determining whether a fuel cut-in condition is satisfied after the fuel cut-off; calculating an optimum valve overlap according to an intake amount, an engine rotation speed, and an ignition timing if the fuel cut-in condition is satisfied after the fuel cut-off; controlling a CVVD apparatus to be at the optimum valve overlap; and performing the oxygen purge at the optimum valve overlap.

Abstract: The silence of a diesel engine is enhanced. A PCM detects an actual supercharging pressure of a gas, and controls an injection mode of a fuel through an injector, thereby executing main injection that is started near a compression top dead center or pilot injection that is executed prior to the main injection depending on an operating state of an engine. If the degree of opening of an accelerator pedal decreases during operation of a large turbocharger, and the actual supercharging pressure is equal to or higher than a predetermined value, the PCM executes cylinder pressure control that allows an interval between a start timing of the pilot injection and a start timing of the main injection to be broader than if the actual supercharging pressure is less than a predetermined value.
