(EN) METHOD FOR DETERMINING A RELATIVE HUMIDITY OF THE AIR IN A MOTOR VEHICLE PASSENGER COMPARTMENT
(FR) PROCÉDÉ DE DÉTERMINATION D'UNE HUMIDITÉ RELATIVE DE L'AIR DANS UN HABITACLE DE VÉHICULE AUTOMOBILE
Abstract
(EN)
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 (HR1) of the air and a temperature (T1) of the air in a sensor integrating at least one temperature sensor and one relative humidity sensor, - calculating the relative humidity (HR2) of the air in said passenger compartment of the motor vehicle from said parameter and a temperature (T2) of the air in the passenger compartment.

L'invention concerne un procédé de détermination d'une humidité relative de l'air dans un habitacle de véhicule automobile, comprenant les étapes suivantes : - détermination d'un paramètre reflétant une humidité spécifique de l'air à partir d'une humidité relative (HR1) de l'air et une température (T1) de l'air dans un capteur intégrant au moins un capteur de température et un capteur d'humidité relative, - calcul de l'humidité relative de l'air (HR2) dans ledit l'habitacle du véhicule automobile à partir dudit paramètre et d'une température (T2) de l'air dans l'habitacle.
