Abstract
A system for a vehicle includes a humidity determination module, a specific humidity module, and a parameter control module. The humidity determination module determines a first specific humidity of air based on a relative humidity of the air measured by a humidity sensor in an intake system of the vehicle. The specific humidity module sets a second specific humidity of the air equal to one of the first specific humidity and a predetermined specific humidity of the air in response to a comparison of a mass air flowrate (MAF) into an engine and a predetermined flowrate. The parameter control module controls at least one operating parameter of an engine based on the second specific humidity.
