Abstract:
Methods and systems are provided for adjusting an engine sound audible to the operator in a vehicle cabin during an engine idle-stop. In one example, responsive to an engine idle-stop, modified versions of a generated engine sound may be played via a dashboard speaker during each of the engine spin-down, engine rest, and engine spin-up. The modified versions of a generated engine sound may at least partially cancel inherent engine spin-up and engine spin-down sounds while maintaining an engine idling sound.
