Abstract

A telematics apparatus for providing driving assistance, and a system and a method are provided. The telematics apparatus receives position information indicating a current position of the telematics apparatus. The telematics apparatus transmits a request signal to the server. According to the request signal, the server obtains the position information, time information indicating a current time of the telematics apparatus, and identification information identifying a user of the telematics apparatus. The telematics apparatus displays driving assistance information received from the server which generates the driving assistance information according to the identification information, the position information, and the time information by searching through a route usage history of a plurality of routes and referring to a plurality of reference values of the routes. The reference value of each route indicates the telematics apparatus user'"'"'s familiarity with that route.

4. The telematics apparatus according to claim 3, wherein the destinations and the driving routes towards the destinations contained in the driving assistance information are ranked.

5. The telematics apparatus according to claim 3, wherein the number of destinations and the number of driving routes towards the destinations contained in the driving assistance information decrease as the current position of the telematics apparatus varies.

6. The telematics apparatus according to claim 3, wherein the at least one driving route towards the destination is selected from a plurality of predicted routes according to the reference values of the predicted routes, and the predicted routes are located from the route usage history by the processing unit according to the identification information, the position information, and the time information.

7. The telematics apparatus according to claim 3, wherein each driving route is composed of several segments, and the driving assistance information contains turn-by-turn navigation information of at least a part of the segments.

8. The telematics apparatus according to claim 3, wherein each driving route is composed of several segments, and each segment is named or categorized at least according to districts, public facilities, or shops.

9. The telematics apparatus according to claim 3, wherein the driving assistance information is displayed in a zoomable map, and the name of each segment varies with the zoom level of the map.

10. The telematics apparatus according to claim 3, wherein, the driving assistance information is displayed in a hierarchical menu, and the name of each segment varies as the hierarchical menu is expanded.

11. The telematics apparatus according to claim 1, wherein the telematics apparatus further comprises at least one of the following elements:

a traffic information database configured to store traffic information;

a weather information database configured to store weather information; and

a commercial information database configured to store shopping mall information;

wherein, the processing unit further searches through at least one of the traffic information database, the weather information database, and the commercial information database to generate the driving assistance information.

12. The telematics apparatus according to claim 1, wherein the driving assistance information further contains at least one of traffic information, weather information and commercial information within a predicted range that the telematics apparatus is going to enter from its current position.

13. The telematics apparatus according to claim 12, wherein when a store'"'"'s activity time of the commercial information is close to or not earlier than a predicted arrival time, the driving assistance information contains the commercial information, and the predicted arrival time indicates an estimated time for the telematics apparatus will arrive at a shopping mall position of the store'"'"'s information from its current position.

14. The telematics apparatus according to claim 1, wherein with respect to each route, the route usage history has another reference value indicating another telematics apparatus user'"'"'s familiarity with that route, wherein the processing unit further refers to another reference value of the route to generate the driving assistance information.

15. The telematics apparatus according to claim 14, wherein, for the user of another telematics apparatus, the another reference value of each route is related to driving frequency or coverage rate of all roads covered within a coverage range.

16. The telematics apparatus according to claim 1, wherein the driving assistance information further contains a hot spot when the distance between two parking points of the telematics apparatus or another telematics apparatus is smaller than a predetermined distance and the stay time is longer than a predetermined time.

17. A method for providing driving assistance information, comprising:

receiving position information indicating a current position of the telematics apparatus by a telematics apparatus;

transmitting a request signal to a server by the telematics apparatus, wherein the server obtains the position information, time information indicating a current time of the telematics apparatus, and identification information identifying a user of the telematics apparatus according to the request signal;
