Abstract

A method for retaining accessory power in a motorized vehicle includes the steps of sensing whether an ignition in the motorized vehicle has been turned to an off position and sensing whether the vehicle doors are closed. The method also includes an occupancy detection system that senses whether a seat is occupied by an occupant and that is also used to enable or disable deployment of an airbag inside the vehicle.

Claims

1. A method for retaining accessory power, the method comprising the steps of:

determining that an ignition device is turned to an off position in a motor vehicle that includes at least one vehicle door;

establishing a predetermined time period for retaining accessory power;

sensing whether the at least one vehicle door is closed;

sensing whether a driver seat, a passenger seat, or a backseat in the motor vehicle is occupied by an occupant;

making retained accessory power available to predetermined vehicle components; and

providing power to and maintaining power of the predetermined vehicle components if the at least one vehicle door is closed or an occupant is occupying a seat.

2. The method of claim 1, further comprising:

terminating the retained accessory power if the time period for retaining accessory power has expired.

3. The method of claim 1, wherein:

power is retained only if the at least one vehicle door is closed or an occupant is occupying any seat but the driver seat.

4. The method of claim 1, wherein:

power is retained only if the at least one vehicle door is closed or an occupant is occupying the passenger seat.

5. The method of claim 1, wherein:

one of the predetermined vehicle components is a vehicle radio.

6. The method of claim 1, wherein:

one of the predetermined vehicle components is a vehicle window.

7. The method of claim 1, wherein the step of sensing whether a seat is occupied by a passenger comprises:

an occupancy detection system sensing the presence of an occupant.

8. The method of claim 7, wherein:

the occupancy detection system is also used to sense an occupant for enabling or disabling deployment of an airbag.

9. A method for retaining accessory power in a motorized vehicle, the method comprising the steps of:

sensing whether an ignition device in the motorized vehicle is turned off;

sensing whether the at least one vehicle door is closed;

sensing whether a seat in the vehicle is occupied by an occupant using an occupancy detection system that is also used to enable or disable deployment of an airbag inside the vehicle.

10. The method of claim 9, further comprising the steps of:

setting a first predetermined period of time in which retained accessory power will be available.

11. The method of claim 10, further comprising the steps of:

terminating the retained accessory power if the time period for providing retained accessory power has expired.

12. The method of claim 10, further comprising the steps of:

initiating a supplemental period in which retained accessory power is available if all seats have been unoccupied and subsequently one of the seats is reoccupied within the first predetermined period of time that retained accessory power will be available.

13. The method of claim 10, further comprising the steps of:

retained accessory power is provided only if the vehicle doors are closed or an occupant is occupying the passenger seat.

14. The method of claim 10, wherein:

retained accessory power is provided only if the vehicle doors are closed or an occupant is occupying any seat but the driver'"'"'s seat.

15. The method of claim 10, wherein:

one of the predetermined vehicle components is a vehicle radio.

16. The method of claim 10, wherein:

one of the predetermined vehicle components is a vehicle window.

17. A system that retains accessory power in a vehicle, said system comprising:

a door sensor that operably senses whether a vehicle door has been opened;

an occupancy detection system that senses the presence of an occupant in a vehicle seat; and

a controller operably connected to a vehicle ignition wherein after an ignition device has been turned to an off position, the controller makes retained accessory power available to vehicle components if the occupancy detection system senses the presence of an occupant or if the door sensor senses that the vehicle door has not been opened.

18. The accessory power retaining system of claim 17, wherein:

the vehicle components are the radio and the windows.

19. The accessory power retaining system of claim 17, wherein:

the occupancy detection system also senses the presence of an occupant for purposes of deployment of an airbag.

20. The accessory power retaining system of claim 17, further comprising:

a timer that is operably connected with the controller and that terminates the retained accessory power after a given time period has expired.

21. The accessory power retaining system of claim 17, further comprising:

a microprocessor and memory, wherein the memory includes a control algorithm adapted to initiate retained accessory power in a motor vehicle.
