Patent ID: 6892808

Claim:
A device for controlling an installation for heating, ventilating and/or air-conditioning a passenger compartment of a motor-vehicle, the device comprising: a first input provided for receiving a set-point value related to an air-heating configuration desired in the passenger compartment; a second input for receiving at least one signal representative of an air-heating parameter, an output linked to at least one actuator for controlling settings of the installation; and a control module connected to the first and second inputs and the output, the control module provided for controlling the at least one actuator as a function of at least one comfort temperature that corresponds to a desired air-heating configuration in the at least one predetermined region of the passenger compartment; the control module including a calculating module for estimating at least one comfort temperature for a passenger situated in at least one predetermined region of the passenger compartment; the calculating module including means for estimating a blow-in temperature and a blow-in speed of the air which a blower of the installation blows into the passenger compartment as a function of the first and second inputs according to aerodynamic and thermal models of the passenger compartment; the calculating module further including means for evaluating an average temperature within the passenger compartment based on the blow-in temperature and the blow-in speed of the air blown into the passenger compartment and the air-heating parameter according to the thermal model; the calculating module further including means for evaluating a temperature and a speed of air in at least one predetermined region of the passenger compartment based on the blow-in temperature and the blow-in speed of the air blown into the passenger compartment and the average temperature within the passenger compartment according to the aerodynamic model; the calculating module further including means for determining the at least one comfort temperature as a function of the average temperature within the passenger compartment and the temperature and the speed of air in the at least one predetermined region of the passenger compartment.
