Abstract
A method for operating a vehicle with an internal combustion engine is provided that includes regulating a pressure in a fuel tank by scheduling an engine start-up event based on a rate of change of the fuel tank pressure to reduce fuel tank venting emissions, where the rate of change of the fuel tank pressure is determined based on an ambient temperature and an in-tank pressure.
