Methods and systems are provided for adjusting noise, vibration, and harshness (NVH) limits for a vehicle based on an occupancy level of the vehicle. The occupancy level is inferred based on a number of occupants and their position within a vehicle, and further based on a degree of interaction of a primary occupant with vehicle controls. As the occupancy level decreases, NVH constraints for operating the vehicle are reduced and one or more vehicle operating parameters nay be based on the reduced NVH constraints.

Methods and systems for NVH-based vehicle powertrain control

Systems and methods for starting an engine that may be started via two different electric machines are described. In one example, the method reserves an amount of torque that is based on a torque capability of a belt integrated starter/generator and the engine is started with the reserved torque if engine starting torque is greater than a torque capability of the belt integrated starter/generator.

Methods and system for starting an engine

Systems and methods for operating an engine that is started via expansion stroke combustion are described. In one example, the method increases air flow through the engine during an engine stopping process so that a larger amount of air may be trapped in a cylinder that is on its expansion stroke so that greater amounts of engine torque may be provided during engine starting.

Methods and system to shutdown an engine

Systems and methods are provided for operating a port fuel and direct injection fuel system of a rolling variable displacement engine (rVDE). In one example, a method may include selecting between controlling a lift pump of the fuel system to output fuel at a mechanically limited pressure and controlling the lift pump to output fuel at a pressure lower than the mechanically limited pressure based on whether port fuel injection is used. In this way, the lift pump may be controlled without feedback from a pressure sensor, reducing system costs, while electrical power consumption increases due to operating the lift pump to output fuel at the mechanically limited pressure are minimized due to the rVDE technology, which reduces port fuel injection usage.

Systems and methods for a dual fuel system of a variable displacement engine

Methods and systems are provided for improving engine restart operations occurring during a transmission shift in a hybrid vehicle. Engine speed is controller during cranking and run-up to approach a transmission input shaft speed that is based on the future gear of the transmission shift. Engine speed is controlled via adjustments to spark, throttle, and/or fuel, to expedite engine speed reaching the synchronous speed.

Methods and systems for starting an engine

Systems and methods for operating a driveline of a hybrid vehicle are disclosed. In one example, output of an electric machine is adjusted after commanding reactivation of all engine cylinder valves that have been deactivated. The electric machine torque may counteract the engine producing torque that is greater than a requested torque due to high intake manifold pressure.

Methods and system for reactivating engine cylinders

A method for operating a vehicle that may be automatically stopped and started is described. In one example, the method includes supply electrical current to a starter motor independently from supplying electrical current to a starter solenoid. In addition, the method includes adjusting and amount of electrical current that is delivered to the starter motor in response to a level of urgency of an automatic engine start.

Methods and system for a stop/start vehicle

Methods and systems are provided for increasing an amount of oxygen in a pre-chamber of a cylinder prior to combustion. In one example, a method may include purging residual gases from a pre-chamber to a cylinder via a pre-chamber air injection, and reducing a flow of the oxygen from the pre-chamber to the cylinder via a cylinder fuel injection directed toward an orifice fluidically connecting the pre-chamber with the cylinder. In this way, a composition of pre-chamber gases may be adjusted during a combustion cycle of a cylinder.

Systems and methods for increasing oxygen levels in an active pre-chamber

Methods are provided for identifying degradation in components of a compressor recirculation valve (CRV). One method may include inferring degradation of the CRV based on adaptation of a compressor surge line outside an expected range.

Methods and systems for detecting compressor recirculation valve faults

Methods and systems are provided for improving fuel efficiency and tailpipe emissions of a variable displacement engine. Fueling is initially disabled in cylinders selected to be deactivated while pumping air through the cylinders to an exhaust after-treatment catalyst, and then valve operation is disabled. On reactivation, if manifold vacuum is dissipated, one bank of cylinders are reactivated while the other bank is operated in DFSO with valves pumping air until manifold vacuum is reestablished.

Methods and systems for engine control

Methods and systems are provided for increasing vehicle maneuverability when operating on sand, snow, or rocky terrain, as well as while performing cornering and sliding maneuvers. Boost path actuators are held in positions that enable manifold pressure to be held above barometric pressure as torque demand changes, including when torque demand drops. Engine torque is reduced or raised via adjustments to one or more of fuel delivery, spark timing, and intake throttle opening.

Method and system for boosted engine system

Systems and methods for activating and deactivating cylinders of an engine that may activate and deactivate one cylinder independent of other cylinders are presented. In one example, an engine cylinder firing fraction and a remainder value that is based on the engine cylinder firing fraction are a basis for activating and deactivating engine cylinders. The systems and methods also provide for transitioning between different cylinder firing fractions.
