Abstract: Processor-implemented methods and systems for aerodynamically optimizing a design geometry of a vehicle body using a convolutional neural network (CNN) are provided. The method may include receiving a signed distance function (SDF) data file that represents the design geometry of the vehicle body. The method includes receiving a range of inflow boundary conditions. The processor processes the SDF over the range of boundary conditions, using the CNN, to generate therefrom drag and lift outputs for the design geometry. The drag and lift outputs may be displayed in the form of one or more intensity maps.

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.

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.

Abstract: An adaptive radiant heating system regulates a climate inside a motor vehicle cabin having a seat for a vehicle occupant. The system includes radiant heating tiles arranged proximate the seat and powered by an energy storage device. The system also includes a first sensor for detecting a position of the occupant and generating a first signal indicative thereof. The system additionally includes a second sensor for detecting a temperature within the cabin and generating a second signal indicative thereof. The system furthermore includes an electronic controller in operative communication with the tiles and the first and second sensors, and configured to regulate the climate proximate the seat via selective control of the tiles. The controller is configured to receive the first and second signals and activate at least one of the tiles in response to the first and second signals, to thereby regulate the climate proximate the seat.
