Abstract:
A temperature control system for a motor vehicle includes a thermotactile user interface having a plurality of adjacent thermoelectric units arranged in an array, each thermoelectric unit having a thermoelectric surface whose temperature varies with an amount of current supplied to the thermoelectric unit. A controller controls the amount of current supplied to each thermoelectric unit such that the temperature of each thermoelectric surface in the array progressively increases or decreases along the array. The system also includes a sensor system that detects a user selection of one of the thermoelectric surfaces as corresponding to a desired temperature. In response to the detected user selection, the controller controls a temperature of a temperature controlled medium of the motor vehicle, e.g., controls the vehicle's cabin climate, to match the temperature of the selected thermoelectric surface.
