  • Publication number: 20200346517
    Abstract: A method of regulating thermal comfort of an occupant of a vehicle cabin uses a radiant heating tile powered via an energy storage device to generate thermal energy. The method also includes detecting the occupant's position via a position sensor and detecting the occupant's surface temperature and detecting a temperature of the tile via at least one temperature sensor. The method additionally includes determining, via an electronic controller, a rate of change of occupant's surface temperature and a difference between the tile temperature and the occupant's surface temperature relative to a predetermined temperature set-point. The method further includes regulating, via the electronic controller, a power input from the energy storage device to the tile in response to the determined rate of change of the surface temperature and the determined difference between the tile temperature and the occupant's surface temperature to thereby regulate the occupant's surface temperature.
