PLUG-IN HYBRID ELECTRIC VEHICLE

摘要

A method of operating a vehicle propulsion system including a motor and an engine, the method comprising of producing a motor output by selectively operating the motor to consume electrical energy stored on-board the vehicle, the motor driving the vehicle; producing an engine output by selectively operating the engine to consume fuel stored on-board the vehicle; and increasing consumption of the fuel by the engine by operating the engine based on a residence time of the fuel stored on-board the vehicle and further based on a profile of ambient conditions over the residence time.
