Method for determining specific humidity of intake air for selectively controlling engine operating parameters, involves controlling operating parameter of engine based on specific humidity of air, that is set based on mass air flow rate
The method involves determining specific humidity of air based on relative humidity of air measured by a humidity sensor (150) in an intake system of a vehicle. Another specific humidity of the air is set based on a comparison of a mass air flow rate (MAF) in an engine (102) and a predetermined flow rate identical to the former specific humidity or predetermined specific humidity. An operating parameter of the engine is controlled based on the latter specific humidity. A filter is applied to the latter specific humidity to obtain third specific humidity of air.
