Abstract
A fuel injection amount calculation method calculates a fuel injection amount to an internal combustion engine of a vehicle. The method can include calculating a relative intake pressure which is a difference between an intake pressure peak of intake air upon intake starting of a cylinder of the internal combustion engine and an intake pressure bottom of the intake air upon intake ending. The method can also include calculating the fuel injection amount based on the relative intake pressure.
