A method includes controlling an electrified vehicle by automatically commanding an output torque from an electric machine if the electrified vehicle is in park and an engine start or stop request has been received. A road grade may be used to determine whether or not to command the output torque.

Vehicle systems and methods for avoiding unintentional electrified vehicle movement and for reducing electrified vehicle noise, vibration, and harshness

A method includes controlling an electrified vehicle by automatically engaging a braking device if the electrified vehicle is in park and an engine start or stop request has been received. Controlling the electrified vehicle includes preventing a brake lamp from illuminating during engagement of the braking device.

Vehicle systems and methods for reducing electrified vehicle noise, vibration, and harshness

A system and method for stopping an internal combustion engine. According to one aspect of the disclosure, a shutdown sequence of the engine includes retarding ignition timing relative to ignition timing prior to initiation of the shutdown sequence, and then advancing ignition timing relative to ignition timing prior to initiation of the shutdown sequence.

Internal combustion engine quick-stop

In order to provide for reduced internal combustion engine exhaust emissions when cold starting an internal combustion engine, there is provided two methods and systems for cold starting an internal combustion engine, and one method and system for shutting down an internal combustion engine. The methods and systems are directed towards: (1) a preheating of a minimum of one thermally activated sensor within an internal combustion engine prior to cold starting of the internal combustion engine; (2) an autocranking of an internal combustion engine while metering fuel into the internal combustion engine and timing ignition within the internal combustion engine such as to reduce internal combustion exhaust emissions when cold starting the internal combustion engine; and (3) a phased shut down of fuel supply control followed by ignition source control when shutting down an internal combustion engine after operating the internal combustion engine.
