Abstract

A method of controlling a temperature in a vehicle passenger compartment of a parked vehicle includes the steps of: (a) sensing a temperature inside the vehicle at a predetermined time; (b) comparing the sensed temperature to a preferred temperature; (c) confirming an absence of any object near a front and a rear of the parked vehicle; (d) turning on an engine of the parked vehicle if the absence of any object is confirmed and the sensed temperature is not the preferred temperature; and (e) utilizing a climate control system to change the temperature inside the vehicle passenger compartment.

Claims

1. A method of controlling temperature in a vehicle passenger compartment of a parked vehicle, comprising the steps of:

sensing a temperature (T_IN) inside the vehicle passenger compartment at a predetermined time (t_P);

comparing the sensed temperature (T_IN) to a preferred temperature (T_P);

confirming an absence of any objects positioned within a distance of a front and a rear of the parked vehicle;

turning on an engine of the parked vehicle if the absence of any object within a distance of the front and the rear of the parked vehicle is confirmed and the sensed temperature (T_IN) is not substantially equal to the preferred temperature (T_P); and

utilizing a climate control system of the parked vehicle to change the temperature (T_IN) inside the vehicle passenger compartment.

2. The method of controlling temperature in a vehicle passenger compartment of a parked vehicle of claim 1, further comprising the steps of comparing the predetermined time (t_P) to a current time (t_C), and initiating the remaining steps when said predetermined time (t_P) is the same as the current time (t_C).

3. The method of controlling a temperature in a vehicle passenger compartment of a parked vehicle of claim 1, further comprising the steps of repeating the step of confirming the absence of any objects positioned within a distance of the front and the rear of the parked vehicle, and turning off the engine of the parked vehicle if the absence of any objects within a distance of the front and the rear of the vehicle is not confirmed.

4. The method of controlling a temperature in a vehicle passenger compartment of a parked vehicle of claim 1, wherein the step of utilizing the climate control system of the parked vehicle includes the step of using a cooling system to lower the temperature inside the vehicle passenger compartment when the sensed temperature (T_IN) is above the preferred temperature (T_P).

5. The method of controlling a temperature in a vehicle passenger compartment of a parked vehicle of claim 4, further comprising the step of opening at least one window of the parked vehicle utilizing at least one drive motor associated with the at least one window.

6. The method of controlling a temperature in a vehicle passenger compartment of a parked vehicle of claim 1, wherein the step of utilizing the climate control system of the parked vehicle includes the step of using a heating system to raise the temperature inside the vehicle passenger compartment when the sensed temperature (T_IN) is below the preferred temperature (T_P).

7. The method of controlling a temperature in a vehicle passenger compartment of a parked vehicle of claim 6, further comprising the step of turning on at least one seat warmer.

8. The method of controlling a temperature in a vehicle passenger compartment of a parked vehicle of claim 6, further comprising the step of turning on at least one side mirror warmer.

9. The method of controlling a temperature in a vehicle passenger compartment of a parked vehicle of claim 1, further comprising the step of turning off the engine of the parked vehicle a predetermined amount of time (t_OFF) after turning on the engine.

10. The method of controlling a temperature in a vehicle passenger compartment of a parked vehicle of claim 1, further comprising the steps of repeating the step of sensing a temperature (T_IN) inside the vehicle passenger compartment at predetermined time periods following the step of turning on the engine of the parked vehicle, and turning off the engine of the parked vehicle when the sensed temperature (T_IN) rises above the preferred temperature (T_P).

11. The method of controlling a temperature in a vehicle passenger compartment of a parked vehicle of claim 10, further comprising the step of delaying the step of turning off the engine of the parked vehicle when the sensed temperature (T_IN) rises above the preferred temperature (T_P) for a predetermined period of time (t_H) following the sensing step that determined the sensed temperature (T_IN) to be above the preferred temperature (T_P).

12. The method of controlling temperature in a vehicle passenger compartment of a parked vehicle of claim 1, further comprising the step of establishing a preferred temperature (T_P) inside the vehicle passenger compartment.

13. The method of controlling temperature in a vehicle passenger compartment of a parked vehicle of claim 12, wherein the establishing step includes programming the preferred temperature (T_P) and the predetermined time (t_P) for sensing an actual temperature (T_IN) inside the vehicle passenger compartment into a climate control program.

14. The method of controlling temperature in a vehicle passenger compartment of a parked vehicle of claim 13, wherein the programming step includes accessing the climate control program utilizing a user interface within the parked vehicle, and setting the preferred temperature (T_P).

15. The method of controlling temperature in a vehicle passenger compartment of a parked vehicle of claim 12, wherein the establishing step includes programming a first preferred temperature (T_P) and a first predetermined time (t_P) for sensing an actual temperature (T_IN) inside the vehicle passenger compartment, and a second preferred temperature (T_P) and a second predetermined time (t_P) for sensing an actual temperature (T_IN) inside the vehicle passenger compartment into a climate control program.

16. The method of controlling temperature in a vehicle passenger compartment of a parked vehicle of claim 1, further comprising the step of establishing a preferred temperature (T_P) inside the vehicle passenger compartment and a predetermined time (t_P) for sensing an actual temperature (T_IN) inside the vehicle passenger compartment.

17. The method of controlling temperature in a vehicle passenger compartment of a parked vehicle of claim 16, wherein the step of utilizing the climate control system of the parked vehicle includes using a cooling system to change the temperature (T_IN) inside the vehicle passenger compartment to a temperature closer to the preferred temperature (T_P).

18. The method of controlling temperature in a vehicle passenger compartment of a parked vehicle of claim 17, wherein the step of utilizing the climate control system of the parked vehicle includes using a heating system to raise the temperature inside the vehicle passenger compartment when the temperature (T_IN) is below the preferred temperature (T_P).

19. The method of controlling temperature in a vehicle passenger compartment of a parked vehicle of claim 17, wherein the step of utilizing the climate control system of the parked vehicle includes using a cooling system to lower the temperature inside the vehicle passenger compartment when the temperature (T_IN) is above the preferred temperature (T_P).

20. The method of controlling a temperature in a vehicle passenger compartment of a parked vehicle of claim 1, further comprising the steps of establishing a preferred temperature (T_P) inside the vehicle passenger compartment, a predetermined time (t_P) for sensing an actual temperature (T_IN) inside the vehicle passenger compartment, and the predetermined period of time (T_RUN).
