Abstract
Methods and systems are provided for improving the operation of a start/stop vehicle having an FEAD-driven AC compressor. During an engine idle-stop, fragrance is dispensed into a vehicle cabin via a fragrance dispensing device integrated with a vent of a vehicle AC unit. The dispensed fragrance masks must smells attributed to an evaporator when the engine is shut-down, thereby extending the duration of idle-stop.
