Claims
- 1. A method of controlling climate in an interior of a vehicle, said method comprising the steps of:
- sensing a temperature in the vehicle interior;
- sensing relative humidity in the vehicle interior
- sensing a temperature outside the vehicle;
- sensing relative humidity outside the vehicle; and
- controlling air flow from outside the vehicle into the vehicle interior in accordance with the sensed temperatures and humidities, said step of controlling air flow including decreasing an air temperature when a relative humidity in the vehicle interior increases.
- 2. A method according to claim 1 further comprising a step of dehumidification of air in the interior of the vehicle by circulating an interior air with withdrawing the air in the interior of the vehicle through an intake duct of a climate control apparatus which duct opens into the vehicle interior.
- 3. A method according to claim 1 further comprising the step of controlling climate in a vicinity of a vehicle windshield as a function of a temperature in the vicinity of the vehicle windshield and as a function of a relative humidity inside of the vehicle in the vicinity of the vehicle windshield to prevent dropping the air saturation point below the dew point on an inner surface of the windshield.
- 4. A method according to claim 3 wherein said step of controlling the climate in the vicinity of the vehicle windshield includes controlling the temperature of an air discharged in the vicinity of the vehicle windshield.
- 5. A method according to claim 4 wherein said step of controlling the climate in the vicinity of the vehicle windshield includes controlling the temperature of the air discharged in the vicinity of the vehicle windshield such that it has a lower relative humidity than the air already located in the vicinity of the vehicle windshield.
- 6. A method of controlling climate in an interior of a vehicle, said method comprising the steps of:
- sensing a temperature in the vehicle interior;
- sensing relative humidity in the vehicle interior;
- sensing a temperature outside the vehicle;
- sensing relative humidity outside the vehicle;
- controlling air flow from outside the vehicle into the vehicle interior in accordance with the sensed temperatures and humidities; and dehumidification of air in the interior of the vehicle by circulating an interior air with withdrawing the air in the interior of the vehicle through an intake duct of a climate control apparatus which duct opens into the vehicle interior, said dehumdification step including regulating the circulated air volume as a function of the relative humidity in the vehicle interior.
- 7. A method of controlling climate in an interior of a vehicle, said method of comprising the steps of:
- sensing a temperature in the vehicle interior;
- sensing relative humidity in the vehicle interior;
- sensing a temperature outside the vehicle;
- sensing relative humidity outside the vehicle
- controlling air flow from outside the vehicle into the vehicle interior in accordance with the sensed temperatures and humidities; and dehumidification of air in the interior of the vehicle by circulating an interior air with withdrawing the air in the interior of the vehicle through an intake duct of a climate control apparatus which duct opens into the vehicle interior, said dehumidification step including regulating the air velocity of the circulated air as a function of the relative humidity in the vehicle interior.
- 8. A method of controlling climate in an interior of a vehicle, said method comprising the steps of:
- sensing a temperature in the vehicle interior
- sensing relative humidity in the vehicle interior
- sensing a temperature outside the vehicle;
- sensing relative humidity outside the vehicle
- controlling air flow from outside the vehicle into the vehicle interior in accordance with the sensed temperatures and humidities; and controlling climate in the vicinity of a vehicle windshield by controlling air flow thereat as a function of temperatures in the vehicle interior and outside of the vehicle and as a function of relative humidity in the vehicle interior such that dropping of air saturation point below the air dew point is prevented.
- 9. A method according to claim 8 wherein said steps of controlling the climate in the vicinity of the vehicle windshield includes controlling it as a function of a global radiation.
- 10. A method according to claim 8 wherein said step of controlling the climate in the vicinity of the vehicle windshield is controlled as a function of a vehicle speed.
