Abstract

A driving route planning system includes a data processing center for collecting real-time traffic information and storing the collected real-time traffic information in a database. The data processing center includes a transmission interface for emitting the stored real-time traffic information receiving requests. The system further includes an electronic device including an electronic route guiding program for planning driving routes, a communication interface for connecting to the data processing center to receive the traffic information transmitted from the data processing center and emit real-time traffic information updating request to the data processing center, and a storage unit for receiving the real-time traffic information received by the communication interface. The electronic route guiding program, when planning a driving route, compares an overlap situation between the real-time traffic information stored in the storage unit and the planned driving route, and takes the overlap situation as a basis to re-plan the driving route.

Claims

1. A driving route planning system comprising:

a data processing center for collecting real-time traffic information and storing the collected real-time traffic information in a database, and data processing center comprising a transmission interface for emitting the stored real-time traffic information stored in the database and receiving requests; and

an electronic device comprising an electronic route guiding program for planning driving routes, a communication interface for connecting to the data processing center to receive the traffic information transmitted from the data processing center and emit real-time traffic information updating request to the data processing center, and a storage unit for receiving the real-time traffic information received by the communication interface, wherein the electronic route guiding program, when planning a driving route, compares an overlap situation between the real-time traffic information stored in the storage unit and the planned driving route, and takes the overlap situation as a basis to re-plan the driving route.

2. The driving route planning system of claim 1, wherein the data processing center is a server.

3. The driving route planning system of claim 1, wherein the data processing center further comprises:

a collecting module for collecting the real-time traffic information; and

a transforming module for transforming the real-time traffic information collected by the collecting module into data having a certain format recognizable by the driving route planning system, and storing the data into the database.

4. The driving route planning system of claim 3, wherein the collected real-time traffic information comprise abrupt or temporarily adjusted real-time traffic information.

5. The driving route planning system of claim 4, wherein the real-time traffic information stored in the database comprise a geographic information of a position where a traffic accident happens and traffic descriptions corresponding to the traffic accident.

6. The driving route planning system of claim 5, wherein the corresponding traffic descriptions comprise one selected from a group consisting of a traffic congestion and a traffic control.

7. The driving route planning system of claim 1, wherein the communication interface of the electronic device and the transmission interface of the data processing center acquire the real-time traffic information stored in the database by a connection mechanism.

8. The driving route planning system of claim 7, wherein the connection mechanism is one selected from a group consisting of Internet, wireless application protocol (WAP), global radio packet service (GPRS), WiFi, cellular digital packet data (CDPD) and unstructured supplementary service data (USSD).

9. The driving route planning system of claim 1, wherein that the transmission interface of the data processing center receives the request means that the communication interface of the electronic device emits traffic information updating request actively, enabling the data processing center to transmit the traffic information stored in the database via the transmission interface to the electronic device.

10. The driving route planning system of claim 1, wherein that the transmission interface of the data processing center emits the traffic information stored in the database means that the data processing center emits real-time traffic information actively via the transmission interface to the electronic device.

11. The driving route planning system of claim 1, wherein the electronic device is one selected from a group consisting of a personal digital assistant (PDA) having a global positioning system (GPS) function, a cellular phone, a smart cellular phone, a GPS system for cars, or a notebook computer.

12. A driving route planning method applied to an electronic device having an electronic route guiding program, for enabling the electronic device to have a driving route planning function, the method comprising:

establishing a data processing center for collecting real-time traffic information and storing the collected real-time traffic information in a database;

enabling the electronic device to execute the electronic route guiding program to plan a driving route; and

enabling the electronic device to acquire the real-time traffic information stored in the database of the data processing center and compare an overlap situation between the acquired real-time traffic information and a planned driving route and take the overlap situation as a basis to re-plan the traffic route.

13. The driving route planning method of claim 12, wherein the data processing center is a server.

14. The driving route planning method of claim 12, wherein the data processing center storing the real-time traffic information in the database further comprises transforming the real-time traffic information collected by the collecting module into data having a certain format recognizable by the driving route planning system.

15. The driving route planning method of claim 12, wherein the collected real-time traffic information comprise abrupt or temporarily adjusted real-time traffic information.

16. The driving route planning method of claim 15, wherein the real-time traffic information stored in the database comprise a geographic information of a position where a traffic accident happens and traffic descriptions corresponding to the traffic accident.

17. The driving route planning method of claim 16, wherein the corresponding traffic descriptions comprise one selected from a group consisting of a traffic congestion and a traffic control.

18. The driving route planning method of claim 12, wherein the electronic device acquires the real-time traffic information stored in the database of the data processing center by a connection mechanism.

19. The driving route planning method of claim 18, wherein the connection mechanism is one selected from a group consisting of Internet, WAP, GPRS, WiFi, CDPD and USSD.

20. The driving route planning method of claim 12, wherein before acquiring the real-time traffic information stored in the database of the data processing center, the electronic device is enabled to emit traffic information updating requests to enable the data processing center to transmit the traffic information stored in the database to the electronic device.

21. The driving route planning method of claim 12, wherein that the transmission interface of the data processing center emits the traffic information stored in the database means that the data processing center emits real-time traffic information actively via the transmission interface to the electronic device.

22. The driving route planning method of claim 12, wherein the electronic device is one selected from a group consisting of a PDA having a GPS function, a cellular phone, a smart cellular phone, a GPS system for cars, or a notebook computer.
