Abstract

A method for inventorying and monitoring an asset located in an vehicle asset management area. The method involves an inventorying of a presence of an asset within an vehicle asset management area based on a detection of a RFID tag associated with the asset within the vehicle asset management area, and a monitoring of the inventoried presence of the asset within the vehicle asset management area based on the RFID tag associated with the asset.

Claims

1. A method of tracking assets within a vehicle, the method comprising the steps of:

(a) identifying assets to be monitored within a vehicle asset management area;

(b) affixing radio frequency identification (RFID) tags to the identified assets;

(c) placing the assets within the vehicle asset management area; and

(d) using a telematics device having a RFID reader to determine which identified assets are within the vehicle asset management area, wherein step (d) is carried out in response to locking of doors; and

(e) monitoring the vehicle asset management area using the RFID reader on the telematics unit until the doors are unlocked.

2. The method of claim 1, further comprising the step of notifying a customer if the RFID reader detects that an identified asset has moved out of the vehicle asset management area.

3. The method of claim 1, further comprising the step of creating an inventory list that contains a unique identifier for each RFID tag.

4. The method of claim 3, further comprising the step of adding to or subtracting from the inventory list when the RFID reader detects that an asset has moved into or out of the vehicle asset management area.

5. The method of claim 1, wherein the assets to be monitored are personal assets or vehicle assets.

6. The method of claim 1, further comprising the step of determining that a particular asset is outside the vehicle asset management area when the asset is moved to a location outside of the functional range of the RFID reader.

7. A method of tracking assets within a vehicle, the method comprising the steps of:

(a) identifying permanent vehicle assets that remain in the vehicle longer than a transient time span;

(b) associating the permanent vehicle assets with an identification number;

(c) linking the permanent vehicle assets with radio frequency identification (RFID) tags;

(d) using a telematics device having a RFID reader to determine which permanent vehicle assets are within a vehicle asset management area; and

(e) notifying a call center when a permanent vehicle asset is removed from the vehicle asset management area.

8. The method of claim 7, further comprising the step of creating an inventory list that contains a unique identifier for each RFID tag correlating to a defined vehicle asset.

9. The method of claim 7, further comprising the step of alerting a vehicle owner if the RFID reader detects that a defined vehicle asset has moved out of the vehicle asset management area.

10. The method of claim 7, wherein a defined vehicle asset is determined to have been removed from the vehicle asset management area when the recognized vehicle asset is outside the functional range of the RFID reader.

11. A method of tracking assets to be monitored within a vehicle, the method comprising the steps of:

(a) attaching a radio frequency identification (RFID) tag to a vehicle part;

(b) detecting the vehicle part within a vehicle asset management area using an RFID reader;

(c) generating a vehicle parts log which records that a vehicle part is located within the vehicle asset management area, wherein the vehicle parts log is associated with a particular identification number; and

(d) updating the vehicle parts log when a vehicle part has moved into or out of the vehicle asset management area.

12. The method of claim 11, wherein the vehicle parts log further comprises a unique identifier for each RFID tag.

13. The method of claim 12, the step of updating the vehicle parts log further comprises adding a vehicle part to or subtracting a vehicle part from the vehicle parts log when the RFID reader detects that a vehicle part has moved into or out of the vehicle asset management area.

14. The method of claim 11, further comprising the step of notifying a central facility if the RFID reader detects that at least one vehicle part has moved out of the vehicle asset management area.

15. The method of claim 11, further comprising the step of notifying a vehicle owner when the RFID reader detects that at least one vehicle part has moved out of the vehicle asset management area.

16. The method of claim 11, wherein the vehicle parts log is created by a user manually recording a unique identifier for each RFID tag to be monitored.

17. The method of claim 11, wherein at least one vehicle part is determined to be outside of the vehicle asset management area when the at least one vehicle part within the vehicle asset management area is outside the functional range of the RFID reader.
