METHOD FOR DETERMINING A RELATIVE HUMIDITY OF THE AIR IN A MOTOR VEHICLE PASSENGER COMPARTMENT

The invention relates to a method for determining a relative humidity of the air in a motor vehicle passenger compartment, comprising the following steps: —determining a parameter reflecting a specific humidity of the air from a relative humidity (HR) of the air and a temperature (T) of the air in a sensor integrating at least one temperature sensor and one relative humidity sensor, —calculating the relative humidity (HR) of the air in said passenger compartment of the motor vehicle from said parameter and a temperature (T) of the air in the passenger compartment.
