Abstract

An off-road navigation system in which an off-road route database is installed in a remote control center and having stored therein a plurality of off-road routes, each off-road route having a starting point and an off-road destination located at a place where no accomplished road can reach. When a vehicle wirelessly sent to the remote control center an off-road navigating request including the data of the desired off-road destination, the server of the remote control center searches the off-road route database for a specific off-road route corresponding to the off-road destination, and wirelessly sends the data of the specific off-road route to the vehicle in response to the navigating request for guiding the driver to the off-road destination through turning points in the specific off-road route.

Claims

1. An off-road navigation system installed in a remote control center, comprising a remote server, a wireless communication module, and an off-road route database, wherein:

said wireless communication module is adapted to wirelessly receive an off-road navigating request which including the position data of an off-road destination, said off-road destination being located at a specific geographical location where no accomplished road can reach;

said off-road route database has stored therein a plurality of off-road routes, said off-road routes including at least one specific off-road route corresponding and reaching to said off-road destination, said off-road routes each having a starting point;

said remote server is adapted to search said off-road route database for said at least one specific off-road route corresponding to the off-road destination of said off-road navigating request, and to control said wireless communication module to wirelessly send out said at least one specific off-road route in response to said off-road navigating request.

2. The off-road navigation system as claimed in claim 1, wherein the starting point of said off-road route is located on an accomplished road.

3. The off-road navigation system as claimed in claim 1, wherein said off-road navigating request further includes the position data of a departure point;

said remote server has further linked thereto an electronic map and a first navigation apparatus, said electronic map having stored therein the data of a plurality of accomplished roads, said first navigation apparatus being adapted to search said electronic map for at least one guiding route respectively corresponding to said at least one specific off-road route, said at least one guiding route each comprising at least one accomplished road passing from said departure point to the starting point of the corresponding specific off-road route;

said wireless communication module is further adapted to wirelessly send out said at least one guiding route in response to said off-road navigating request.

4. The off-road navigation system as claimed in claim 3, wherein said off-road navigating request is wirelessly sent from a vehicle, and said departure point is the current position of the vehicle sending said off-road navigating request.

5. An on-board off-road navigation system installed in a vehicle, comprising:

a global positioning module adapted to calculate the current position of said vehicle;

a wireless communication module adapted to wirelessly send out an off-road navigating request and to wirelessly receive at least one specific off-road route, said off-road navigating request including the position data of an off-road destination, said off-road destination being located at a specific geographical location where no accomplished road can reach, said at least one specific off-road route each including an off-road navigation data traveling from a respective starting point to said off-road destination; and

a second navigation apparatus adapted to fetch the current position of said vehicle from said global positioning module, and to guide said vehicle to said off-road destination subject to the off-road navigation data of said at least one specific off-road route.

6. The on-board off-road navigation system as claimed in claim 5, wherein the starting point of said off-road route is located on an accomplished road.

7. The on-board off-road navigation system as claimed in claim 5, wherein said wireless communication module is further adapted to wirelessly receive at least one guiding route which corresponding to said at least one specific off-road route respectively, said at least one guiding route each comprising at least one accomplished road passing from the current position of said vehicle to the starting point of the corresponding specific off-road route.

8. The on-board off-road navigation system as claimed in claim 5, further comprising an electronic map, said electronic map having stored therein the data of a plurality of accomplished roads, said electronic map being linked to said second navigation module such that said second navigation module is capable of searching said electronic map for at least one guiding route respectively corresponding to said at least one specific off-road route, said at least one guiding route each comprising at least one accomplished road passing from the current position of said vehicle to the starting point of the corresponding specific off-road route.

9. The on-board off-road navigation system as claimed in claim 5, further comprising a memory means adapted to store said at least one specific off-road route.

10. The on-board off-road navigation system as claimed in claim 9, wherein said memory means comprises at least one IC memory card.
