21. A method for a vehicle propulsion system including a motor and an engine, comprising:
-
operating the motor and engine to consume electrical energy and fuel, respectively, to propel the vehicle; and increasing engine fuel consumption relative to motor electrical energy consumption based on residence time of fuel stored on-board the vehicle being greater than a threshold, the threshold adjusted based on an in-tank pressure of a fuel tank ullage space. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
