Abstract: In accordance with an aspect of the present disclosure, cruise control of an automotive vehicle in a fuel economy cruise control mode controls vehicle speed to be within a fuel economy speed band about a cruise control set speed so that instantaneous fuel economy is at least equal to average fuel economy.

Abstract: A diagnostic system and method for a gasoline particulate filter (GPF) of an exhaust system of a vehicle comprise at least one heater associated with at least one oxygen (O2) sensor disposed proximate to the GPF in the exhaust system and a controller configured to determine a status of the GPF based on a duty cycle of the at least one O2 sensor heater and, based on the determined status of the GPF, detect a malfunction of the GPF or whether to regenerate the GPF.

Abstract: An evaporative emissions (EVAP) system for a vehicle includes a waste heat control valve configured to direct an exhaust gas from an exhaust treatment system, the waste heat control valve being positioned at a point downstream from a catalyst of the exhaust treatment system, a vapor canister configured to store a fuel vapor evaporated from a liquid fuel housed in a fuel tank of the vehicle, and a heat exchanger connected to (i) the fuel tank, (ii) the waste heat control valve, and (iii) the vapor canister, the heat exchanger being configured to (a) utilize the exhaust waste heat to evaporate the fuel vapor from the liquid fuel and (b) provide the evaporated fuel vapor to the vapor canister. A method of operating the EVAP system includes controlling the waste heat control valve and a fuel pump to provide the vapor canister with a desired amount of fuel vapor.
