Abstract: A battery system includes a power cell and a heat exchanger abutting the power cell. The heat exchanger includes a cooling medium reservoir, a heat exchange member, and a wicking structure disposed between the cooling medium reservoir and the heat exchange member. The wicking structure provides a fluid pathway from the cooling medium reservoir to the heat exchange member and from the heat exchange member to the cooling medium reservoir.

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.

Abstract: A vehicle braking system including a brake pedal in communication with a wheel brake, a brake actuation system, a braking system controller, an on-board driver communication system, and a controller is described. Parameters associated with a braking request, a brake actuation command and vehicle operation are monitored during each braking event, and segmented the into parameters associated with a static portion of the braking event and parameters associated with a dynamic portion of each braking event, evaluate the parameters associated with the static portion of the braking event and evaluate the parameters associated with the dynamic portion of the braking event, and assess a state of health of the braking system based upon the evaluation of the parameters. The assessment of the state of health of the braking system is communicated to a vehicle driver via the on-board driver communication system.

Abstract: Systems and method are provided for collaboration between autonomous vehicles. In one embodiment, a processor-implemented method for coordinating travel between multiple autonomous vehicles is provided. The method includes sending a collaboration request to one or more vehicles in an area to form a group to perform a mission, receiving an acceptance of the collaboration request to join the group wherein the group includes a plurality of vehicles, cooperating in assigning leading functions for the group to one or more of the plurality of vehicles in the group, cooperating in mission negotiations for the group, cooperating in determining a formation for the group, and cooperating in generating a trajectory for the group. The vehicles in the group are operated in accordance with the determined formation and generated trajectory.
