  • Publication number: 20200189352
    Abstract: A vehicle a sensor system disposed adjacent to a headrest portion of a seat within a passenger compartment of the vehicle. The sensor system includes at least one of an air velocity sensor, an air temperature sensor, a radiant heat flux sensor, a heat flux sensor, or a humidity sensor. The sensor system is positioned near the headrest, facing a forward end of the vehicle, in a position that is not blocked by a head of a passenger seated in the seat. The sensor system provides data related to the air velocity, the air temperature, the radiant heat flux, the heat flux, or the relative humidity, enabling a climate controller to accurately calculate a current Equivalent Homogenous Temperature (EHT) of a passenger seated in the seat. The climate controller may then control a climate system of the vehicle based on the calculated EHT to provide a desired EHT.
