DRIVER PERSONALIZED CLIMATE CONDITIONING
First Claim
1. Apparatus in a transportation vehicle occupied by a person within a passenger cabin, comprising:
- a skin temperature sensor for measuring an actual skin temperature of the person;
a cabin temperature sensor for measuring an actual cabin temperature of ambient air within the passenger cabin;
an HVAC system for providing heated and cooled air flow into the passenger cabin;
a controller module storing a target cabin temperature, wherein the controller module controls the HVAC system according to a first error between the target cabin temperature and the actual cabin temperature, wherein the actual cabin temperature is filtered according to a first time constant; and
a personalization module storing a target skin temperature, wherein the personalization module determines an offset to be applied to the target cabin temperature according to a second error between the target skin temperature and the actual skin temperature, wherein the actual skin temperature is filtered according to a second time constant longer than the first time constant.

Abstract
An HVAC system for a vehicle includes a skin temperature sensor for measuring an actual skin temperature of the driver and a cabin temperature sensor for measuring an actual cabin temperature of ambient air within the passenger cabin. A controller module stores a target cabin temperature, wherein the controller module controls the HVAC system according to a first error between the target cabin temperature and the actual cabin temperature. The actual cabin temperature is filtered according to a first time constant. A personalization module stores a target skin temperature, wherein the personalization module determines an offset to be applied to the target cabin temperature according to a second error between the target skin temperature and the actual skin temperature. The actual skin temperature is filtered according to a second time constant longer than the first time constant.

16. A method of controlling heated and cooled air flow from an HVAC system into a passenger cabin of a transportation vehicle occupied by a person, comprising the steps of:
-
measuring an actual skin temperature of the person; measuring an actual cabin temperature of ambient air within the passenger cabin; storing a target cabin temperature; filtering the actual cabin temperature according to a first time constant; controlling the HVAC system according to a first error between the target cabin temperature and the filtered actual cabin temperature; storing a target skin temperature; filtering the actual skin temperature according to a second time constant longer than the first time constant; and determining an offset for updating the target cabin temperature according to a second error between the target skin temperature and the filtered actual skin temperature. - View Dependent Claims (17, 18, 19, 20, 21, 22)

23. A method of providing personalized climate control of a person in a seated position within a transportation vehicle, comprising the steps of:
-
collecting a first temperature measurement from a first infrared sensor directed toward a first region of the seated position corresponding to the left side of the face of the person; collecting a second temperature measurement from a second infrared sensor directed toward a second region of the seated position corresponding to the right side of the face of the person; measuring an actual cabin temperature of ambient air within the passenger cabin; comparing each of the first and second temperature measurements with the actual cabin temperature; selecting the one of the first or second temperature that deviates the most from the actual cabin temperature as an actual skin temperature; and controlling ventilation applied to the person based on the actual skin temperature.
