the controller is configured to control the HVAC system in accordance with the first desired temperature and the first data to maintain the first temperature of the air or the surface in the cabin at or near the first desired temperature; and
the controller is further configured to control the heater/cooler in accordance with the second desired temperature and the second data to maintain the second temperature of the cover or the cushion of the seat at or near the second desired temperature.
6 . The system of claim 5 wherein the first desired temperature is different from the second desired temperature.
7 . The system of claim 1 wherein the controller is configured to maintain the second temperature of the cover or the cushion of the seat at or near the desired temperature plus or minus an offset.
8 . The system of claim 7 wherein the offset is in a range of 1 to 10 degrees.
9 . A system for controlling a temperature of a cabin and a seat of a vehicle, the system comprising:
an HVAC system configured provide a flow of air to heat an air into the cabin of the vehicle;
a first temperature sensor positioned in the cabin of the vehicle, the first temperature sensor configured to detect a first temperature of the air or a surface inside the cabin;
a heating element positioned in an interior of the seat of the vehicle, the heating element configured to heat a cover or a cushion of the seat; and
a second temperature sensor positioned in the interior or under the cover of the seat of the vehicle, the second temperature sensor configured to detect a second temperature of the cover or the cushion of the seat; and
a controller configured to receive a desired temperature from a user of the vehicle, the controller configured to control a third temperature of the flow of air from the HVAC system in accordance with the first temperature and the desired temperature to maintain the first temperature at or near the desired temperature, the controller further configured to control a fourth temperature of the heating element in accordance with the second temperature and the desired temperature to maintain the second temperature at or near the desired temperature.
