Abstract

An occupant environment conditioning system for a vehicle includes a controller that selectively operates at least one device for altering an environment of a vehicle occupant based a power cost analysis.

Claims

1. An occupant environment conditioning system for a vehicle comprising:

a user input device indicating a desired environmental condition of a vehicle occupant compartment;

a vehicle system input device indicating at least one parameter of the vehicle;

a plurality of occupant environment conditioning device that generate heating or cooling for altering an environment of the vehicle occupant compartment; and

a controller responsive to the desired environmental condition of occupant compartment indicated by the user input device, and the vehicle parameter indicated by the system input device to operate the occupant environment conditioning devices for generating heating or cooling based on a power consumption.

2. The occupant environment conditioning system of claim 1 wherein the vehicle system input device is an occupant sensor for indicating the presence of an occupant in a vehicle seat.

3. The occupant environment conditioning system of claim 1 wherein the plurality of occupant environment conditioning devices includes a device that is integrated into a vehicle seat.

4. The occupant environment conditioning system of claim 1 wherein the plurality of occupant environment conditioning devices includes a thermo-electric device.

5. The occupant environment conditioning system of claim 4 wherein the thermo-electric device is a Peltier device.

6. The occupant conditioning system of claim 4 wherein the thermo-electric device is a ceramic device.

7. The occupant environment conditioning system of claim 3 wherein the device integrated into the vehicle seat is a ventilated device.

8. The occupant environment conditioning system of claim 1 wherein the user input device is one of a key fob and a remote control.

9. The occupant environment conditioning system of claim 1 further comprising:

a plurality of user input devices each indicating a desired condition of a plurality of climate zones defined within the vehicle occupant compartment,

wherein the controller is responsive to input from the plurality of user input devices to operate the plurality of occupant environment conditioning devices.

10. The occupant environment conditioning system of claim 1 further comprising:

a plurality of vehicle system input devices wherein the controller is responsive to input from the plurality of vehicle system input devices to operate the plurality of occupant environment conditioning devices.

11. A method of operating an occupant environment conditioning system for a vehicle comprising the steps of:

a. providing a user input device that indicates a desired condition of a vehicle passenger compartment;

b. providing a vehicle system input device that indicates at least one parameter of the vehicle;

c. providing a device that generates heating or cooling for altering an environment of a vehicle occupant;

d. providing a controller programmed a power management algorithm including a power cost analysis;

e. evaluating the desired condition indicated by the user input device, and the vehicle parameter indicated by the system input device with the power management algorithm; and

f. operating the device with the controller based at least in part upon the evaluating in step e.

12. The method of claim 11 further comprising the steps of:

g. defining a plurality of occupant climate zones within the vehicle; and

h. determining the occupancy of at least one climate zone with the vehicle system input device;

wherein the power management algorithm is response to the occupancy determined in step h.

13. The method of claim 11 wherein the device is associated with a ventilation system including an air handler and wherein the operating in step f. includes deactivating the device and one of running the air handler in a ventilated mode and a recirculation mode.

14. An occupant environment conditioning system for a vehicle comprising:

a vehicle system input device indicating at least one parameter of the vehicle;

an occupant environment conditioning device for altering an environment of a vehicle occupant; and

a controller that operates the device based on the vehicle parameter indicated by the system input device.

15. The system of claim 14 wherein the parameter of the vehicle is one of the presence of an occupant in a vehicle seat and a position of an occupant in a vehicle seat.

16. The system of claim 15 wherein the system input device is an occupant sensor for an airbag assembly.
