Abstract

A method of controlling a sunroof of a parked vehicle is provided. The method includes the steps of: monitoring a state of an engine; monitoring a state of the sunroof; monitoring a state of at least one accessory; initiating a timer when the state of the engine changes to an off state, the state of the sunroof is an open state, and the state of the at least one accessory is an off state; and closing the sunroof a period of time after initiation of the timer. The method may further include sensing for precipitation throughout the period of time, and closing the sunroof upon sensing precipitation regardless of whether the period of time has elapsed. The method may further include sensing for an occupant within the vehicle when the period of time has elapsed or when precipitation is sensed, and foregoing the step of closing the sunroof if an occupant is sensed.

Claims

1. A method of controlling a sunroof of a parked vehicle, comprising the steps of:

determining a state of an accessory after a state of an engine changes from an on state to an off state;

initiating a timer when the state of said engine changes from the on state to the off state if said accessory is in an off state;

closing the sunroof after a period of time has elapsed if said engine and said accessory remain in off states;

sensing for precipitation throughout the period; and

closing the sunroof and sensing for motion within a passenger compartment upon sensing precipitation regardless of whether the period of time has elapsed, and foregoing the step of closing the sunroof if motion is sensed within the passenger compartment.

2. The method of controlling a sunroof of a parked vehicle of claim 1, further comprising the step of monitoring a state of the door locks and initiating the timer only if the state of the door locks is locked.

3. The method of controlling a sunroof of a parked vehicle of claim 1, wherein said accessory is a non-engine, vehicle battery powered accessory.

4. The method of controlling a sunroof of a parked vehicle of claim 1, wherein said accessory is a radio, a CD player, a navigational display, a power door, or a power window.

5. A method of controlling a sunroof of a parked vehicle, comprising the steps of:

determining a state of an accessory after a state of an engine changes from an on state to an off state;

initiating a timer when the state of said engine changes from the on state to the off state if said accessory is in an off state;

sensing for precipitation;

sensing a presence of an occupant within one or more seats of the vehicle within a passenger compartment;

closing the sunroof after a period of time has elapsed if said engine and said accessory remain in off states, or closing the sunroof during the period of time upon sensing precipitation, and foregoing the step of closing the sunroof if motion is sensed within the passenger compartment.

6. The method of controlling a sunroof of a parked vehicle of claim 5, further comprising the step of monitoring a state of the door locks and initiating the timer only if the state of the door locks is locked.

7. The method of controlling a sunroof of a parked vehicle of claim 5, wherein said accessory is a non-engine, vehicle battery powered accessory.

8. The method of controlling a sunroof of a parked vehicle of claim 5, wherein said accessory is a radio, a CD player, a navigational display, a power door, or a power window.

9. The method of controlling a sunroof of a parked vehicle of claim 5, wherein the step of sensing a presence of an occupant within one or more seats of the vehicle within the passenger compartment includes the step of sensing for movement of the occupant.

10. The method of controlling a sunroof of a parked vehicle of claim 5, wherein the step of sensing a presence of an occupant within one or more seats of the vehicle within the passenger compartment includes the step of sensing a weight of the occupant.

11. A circuit for controlling a sunroof of a parked vehicle, comprising:

a first control module for monitoring a state of an engine of the vehicle;

a second control module for monitoring a state of at least one accessory;

a timer, said timer initiating when the state of said engine changes from the on state to the off state if said accessory is in an off state;

a precipitation sensor;

an occupancy sensor;

a third control module, responsive to said first and second control modules via a communication network, said timer, and said precipitation and occupancy sensors, for closing the sunroof and sensing for motion within a passenger compartment upon sensing precipitation regardless of whether the period of time has elapsed, and foregoing closing the sunroof if motion is sensed within the passenger compartment.

12. The circuit for controlling a sunroof of a parked vehicle of claim 11, wherein the third control module communicates with said occupancy sensor via said communication network.

13. The circuit for controlling a sunroof of a parked vehicle of claim 11, wherein the third control module communicates with the precipitation sensor via said communication network.

14. The circuit for controlling a sunroof of a parked vehicle of claim 11, wherein said occupancy sensor is an infrared sensor.

15. The circuit for controlling a sunroof of a parked vehicle of claim 11, wherein said occupancy sensor is a load sensor.

16. The circuit for controlling a sunroof of a parked vehicle of claim 11, wherein said occupancy sensor is a motion sensor.

17. The method of controlling a sunroof of a parked vehicle of claim 11, wherein said at least one accessory is a non-engine, vehicle battery powered accessory.

18. The method of controlling a sunroof of a parked vehicle of claim 11, wherein said at least one accessory includes at least one of a radio, a CD player, a navigational display, a power door, or a power window.

19. A vehicle incorporating the circuit for controlling a sunroof of a parked vehicle of claim 11.
