Abstract: The present invention relates generally to improving the fuel efficiency of autonomous vehicles by operating either (1) at a first effective engine displacement that takes into account noise, vibration and harshness (NVH) when the vehicle is occupied or (2) at a second effective engine displacement, without concern for occupant NVH, when the vehicle is not occupied. The second effective engine displacement is typically more fuel efficient than the first effective engine displacement, but result in a higher level of NVH compared to the first effective engine displacement.
