Abstract

A vehicle charge meter for tracking a path of a vehicle is described. The vehicle charge meter comprises a receiver, a memory, a local controller, and a receipt documentation device. The receiver, the memory, and the receipt documentation device are all coupled to the local controller. The receiver is used for receiving RF signals and extracting positioning data from the signals. The memory includes a database storing relationships between positioning data and toponyms. The local controller is then used for retrieving at least one toponym corresponding to the extracted positioning data. As such, the receipt documentation device can document the retrieved toponym in an electronic receipt or on a paper receipt.

Claims

1. A vehicle charge meter for tracking a path of a vehicle, said vehicle charge meter comprising:

a receiver for receiving a plurality of signals and extracting positioning data from said plurality of signals;

a memory comprising a database storing relationships between a plurality of positioning data and a plurality of toponyms;

a local controller coupled to said receiver and said memory for retrieving at least one toponym from said plurality of toponyms corresponding to said extracted positioning data; and

a receipt documentation device coupled to said local controller for documenting said retrieved toponym.

2. The vehicle charge meter as claimed in claim 1, further comprising:

a tachometer for detecting a velocity of said vehicle; and

a timer for detecting a traveling time of said vehicle,

wherein said local controller is coupled to said tachometer and said timer for calculating a traveling distance and a total fare in accordance with said velocity and said traveling time of said vehicle detected, and said receipt documentation device documents said traveling distance, said traveling time, and said total fare.

3. The vehicle charge meter as claimed in claim 1, wherein said receipt documentation device comprises a printer printing out said retrieved toponym on a paper receipt.

4. The vehicle charge meter as claimed in claim 1, further comprising:

a speaker coupled to said local controller for audibly prompting said retrieved toponym.

5. The vehicle charge meter as claimed in claim 1, further comprising:

a display coupled to said local controller for displaying said retrieved toponym.

6. The vehicle charge meter as claimed in claim 1, further comprising:

a smart card reader coupled to said local controller for cashless payment.

7. The vehicle charge meter as claimed in claim 1, wherein said plurality of signals comprises a plurality of Global Positioning System (GPS) signals.

8. The vehicle charge meter as claimed in claim 1, wherein said plurality of signals comprises a plurality of location based service (LBS) signals.

9. The vehicle charge meter as claimed in claim 1, wherein said positioning data comprises geodetic coordinates of longitude and latitude.

10. The vehicle charge meter as claimed in claim 1, further comprising:

an inertial navigation device coupled to said local controller for automatically detecting a turning point of said vehicle, wherein a turning point toponym correspondent to said turning point is documented by said receipt documentation device.

11. A vehicle charge meter for tracking a path of a vehicle, said vehicle charge meter comprising:

a receiver for receiving a plurality of signals and extracting positioning data from said plurality of signals;

a local controller coupled to said receiver generating a tracking command including said extracted positioning data;

a transceiver coupled to said local controller for transmitting said tracking command to a remote server comprising a database, said database storing relationships between a plurality of positioning data and a plurality of toponyms, said transceiver also for retrieving a tracking response from said remote server, wherein said tracking response includes a toponym correspondent to said extracted positioning data; and

a receipt documentation device coupled to said local controller for documenting said toponym.

12. The vehicle charge meter as claimed in claim 11, wherein said transceiver communicates with said remote server through a wireless local area network (WLAN).

13. The vehicle charge meter as claimed in claim 11, wherein said transceiver communicates with said remote server through a Global System for Mobile communication (GSM) service.

14. The vehicle charge meter as claimed in claim 11, wherein said transceiver communicates with said remote server through a Code Division Multiple Access (CDMA) service.

15. A method for tracking a path of a vehicle, comprising:

receiving a plurality of starting point positioning signals at a starting point;

generating a starting point toponym corresponding to said starting point positioning signals received at said starting point;

choosing a point of interest (POI);

receiving a plurality of POI positioning signals at said POI;

generating a POI toponym corresponding to said POI positioning signals received at said POI;

receiving a plurality of destination positioning signals at a destination;

generating a destination toponym corresponding to said destination positioning signals received at said destination; and

documenting said starting point toponym, said POI toponym, and said destination toponym.

16. The method as claimed in claim 15, further comprising:

receiving a plurality of turning point positioning signals at a turning point of said path;

generating a turning point toponym corresponding to said turning point positioning signals received at said turning point; and

documenting said turning point toponym.

17. The method as claimed in claim 15, further comprising:

detecting said turning point automatically by an inertial navigation device.

18. The method as claimed in claim 15, further comprising:

audibly prompting said starting point toponym, said POI toponym, and said destination toponym; and

displaying said starting point toponym, said POI toponym, and said destination toponym on a display.

19. The method as claimed in claim 15, wherein said starting point positioning signals, said POI positioning signals, and said destination positioning signals are Global Positioning System (GPS) signals.

20. The method as claimed in claim 15, wherein said starting point positioning signals, said POI positioning signals, and said destination positioning signals are location based service (LBS) signals.

21. The method as claimed in claim 15, wherein said generating said POI toponym comprises:

querying a database in said vehicle storing relationships between a plurality of positioning data and a plurality of toponyms.

22. The method as claimed in claim 15, wherein said generating said point of interest toponym comprises:

transmitting a tracking command from said vehicle to a remote server;

querying a database stored in said remote server to generate said POI toponym in accordance with said tracking command;

generating a tracking response including said POI toponym; and

transmitting said tracking response from said remote server back to said vehicle.
