Abstract

A system and method for controlling an internal combustion engine include anticipating vehicle launch in response to vehicle position relative to a traffic stream and controlling automatic restart and shut down in response to an anticipated vehicle launch to prevent an automatic engine shut down or to initiate an automatic engine restart. Embodiments include determining vehicle position and traffic position using GPS coordinates. Automatic restart may be initiated in response to movement of a forward vehicle away from the vehicle or in response to a signal from a traffic control device, for example. Automatic shutdown may be inhibited in response to movement of a forward vehicle in cross traffic, in response to a turn indicator being active, or in response to wheel angle, for example.

Description

technical field [0001] The present disclosure relates to systems and methods for automatic shutdown and restart of internal combustion engines to enhance vehicle starting performance. Background technique [0002] Assisted Direct Start (ADS) engines apply several factors to determine when to stop and restart the engine to reduce fuel consumption and emissions while the vehicle is stationary. Typically, engine shutdown occurs when the wheel speed is zero and the brake pedal is depressed (for automatic transmissions), or when the transmission is in neutral and the clutch pedal is depressed (for manual transmissions). Other factors may include engine coolant temperature, battery state of charge, fuel line pressure, A / C operation, and other factors that may be used to prevent engine shutdown and / or initiate engine restart. Physical limitations of the ADS system related to engine / transmission inertia, starter design, combustion control limitations, etc. can also place constraint...
