Abstract: The present invention relates generally to techniques for improving fuel efficiency of a vehicle powered by an internal combustion engine capable of operating at various displacement levels. An autonomous driving unit or cruise controller selects when possible an engine torque output that corresponds to a fuel efficient displacement level. The resultant vehicle speed profile and NVH level is acceptable to vehicle occupants.

Abstract: Various methods and arrangements for controlling catalytic converter temperature are described. In one aspect, an engine controller includes a catalytic monitor and a firing timing determination unit. The catalytic monitor obtains data relating to a temperature of a catalytic converter. Based at least partly on this data, the firing timing determination unit generates a firing sequence for operating the engine in a skip fire manner. Another aspect of the invention relates to an engine exhaust system that can help expedite the heating of a catalytic converter.

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.
