Abstract
An automatic engine stop-start (ESS) system for a vehicle with an internal combustion engine includes a brake pedal, a gear shifter configured to shift a transmission between park, reverse, neutral, and drive, and a controller. The controller is configured to command an ESS engine stop when the gear shifter is in drive, the vehicle is stopped, and the brake pedal is pressed, prevent an ESS engine restart when the gear shifter is shifted from drive to park, and provide, when the ESS engine restart is prevented, a warning notification to a driver that the engine is keyed-on.
