1 FIG. 10 illustrates the system architecture of a terrain navigation system according to a first embodiment of the invention. The terrain navigation system includes an onboard off-road navigation unit installed in a vehicle M, which on-board off-road navigation unit includes a GPS (Global Positioning System) module 21 , a wireless communication module 22 , a second navigation device 23 and a memory 25 and a remote control center 1 on that a remote server 10 , a wireless communication module 11 and a terrain route database 12 having.

The wireless communication module 22 of the vehicle M and the wireless communication module 11 of the remote control center 1 can communicate with each other. According to this embodiment, the wireless communication modules 11 and 22 GPRS (general packet radio service) facilities that can wirelessly send and receive messages using voice, short messages or digital data.

The terrain route database 12 has stored the information of a plurality of terrain routes. Each terrain route leads from a starting point over a number of branch points to a terrain destination without a finished road. The starting point of each terrain route may be positioned on a completed road or at any branch point of one of the terrain routes. The terrain routes may terminate at the terrain destination or pass over the terrain destination to other branch points.

With reference also to 2 For example, when the driver desires to drive the vehicle M to a terrain destination D, such as a hot water source on a whitewater current, the off-road navigation request N1 may be to the remote control center 1 by means of the wireless communication system 22 of the vehicle M wirelessly. The terrain navigation request N1 has all the position data of the terrain destination D.

Referring again to 1 and 2 For example, the driver must drive the vehicle M along a bottleneck on the mountain to drive upstream since the terrain target is a hot water source of white water flow. Has the wireless communication module 11 of the remote control center 1 receive the off-road navigation request N1, the remote server searches 10 the terrain route database 12 after a corresponding specific terrain route R1 having a number of branch points X1, X2, X3, X4, and associated terrain navigation data associated with the provided terrain destination D, and then transmits the search data of the specific terrain route R1 and the there with connected navigation data by means of the wireless communication module 11 of the remote control center 1 wireless to the wireless communication module 22 in response to the terrain navigation request N1, what is the wireless communication module 22 allows the received data in memory 25 store (which may be, for example, an IC memory card).

As in 2 is shown, the departure point C1 of the vehicle M is just the starting point S1 of the aforementioned specific Gelanderoute R1 and is located on a finished road. At this time, the second navigation device asks 23 the current position of the vehicle M from the GPS module 21 and compares the retrieved data with the specific terrain route R1 stored in memory 25 is stored, and then displays the comparison result on the display screen 231 the second navigation device 23 , shown in 3 , to guide the driver from the starting point S1 to the destination D via the branch points X1, X2, X3, X4. The second navigation device 23 Further, when the driver drives the vehicle M to the area destination D, the driver can also voice the corresponding terrain navigation data to the driver.

With reference to 4 When driving uphill, the driver drives the vehicle M along the right bank of the stream to the first branch point X1 near a large rock and then turns the vehicle M to the left and then drives the vehicle M through the stream via the second branch point X2 to the third branch point X3 on the left bank of the stream and then drives the vehicle M from the third branch point X3 in the direction of the fourth branch point X4 and then reaches the terrain destination D. Stromseitig big trees, alternate locations or any unusual landmarks on the Off-road routes can be used to guide the driver to the destination.

The terrain routes (eg, stream-tracking routes, sand-race routes, or hot-water source-tracking routes) stored in the terrain route database 12 , become from the remote control center 1 preferably obtained by instructing humans to test certain landscape points or terrain targets and collect data from each branch point and then the checked and collected data in the terrain route database 12 record. Because the terrain routes are in solitary terrain, their course may change due to the weather (eg, an earthquake, landslide, or storm). The remote control center 1 can regularly or irregularly instruct people to monitor the terrain routes, making the terrain route database 12 can be updated on time. Customers or cooperating groups of vehicles can use the remote control center 1 actively present a report after driving along the terrain routes, making it the remote control center 1 allows the content of the terrain route database 12 to update. Therefore, the remote control center 1 the updated data of the terrain route database 12 Send in time to the vehicle M, which improves the safety of the accuracy of the terrain routes.

5 Fig. 10 illustrates the system architecture of a second embodiment of the invention. This alternative form is substantially the same as that of the aforementioned first embodiment except for the added electronic card 13 and the first navigation device 14 in the remote control center 1 , The electronic card 13 is arranged to store the data of a plurality of completed roads.

Referring to 6 and turn on 5 the departure point C2 is the current position of the vehicle M located on a completed street in a city (away from the mountain side). Has the wireless communication module 11 of the remote control center 1 receive a terrain navigation request N2 having a terrain destination D and the coordinates of the departure point C2 from the vehicle M, the remote server searches 10 the terrain route database 12 , which are related to the provided data of the desired wild-current hot-water source, positioned on the terrain destination D, and obtains from the search result three specific terrain routes R1, R2 and R3 to the wild-current hot-water source. The specific terrain routes R1, R2 and R3 each have a starting point S1, S2, S3 located on a completed road. Thereafter, the first navigation device searches 14 the electronic card 13 according to the corresponding guide routes G1, G2, G3, formed based on completed roads from the departure point C2 to the corresponding starting points S1, S2, S3, and then wirelessly transmits the data of the specific terrain routes R1, R2, R3 and the respective guidance routes G1, G2 , G3 to the wireless communication module 22 of the vehicle M in response to the terrain navigation request N2, which is the wireless communication module 22 allows the received data in memory 25 save.

As a result, the remote control center has 1 three proposed routes from the departure point C2 of the vehicle M to the desired destination D have been found as follows:

• (1) Depart from the departure point C2 and then travel along the route G1 to the starting point S1 and then moving along the corresponding specific terrain route R1 to the terrain destination D;
• (2) Departing from the departure point C2 and then driving along the Guide route G2 to the starting point S2 and then moving along the corresponding specific terrain route R2 to the terrain destination D; and
• (3) Departing from the departure point C2 and then driving along the Guide route G3 to the starting point S3 and then moving along the corresponding specific terrain route R3 to the destination D.

After the vehicle M has received the aforementioned three suggested routes, it displays the data on the display screen of the second navigation device 23 to be selected by the driver. For example, the driver may select the combination of the simple guidance route G2 and the dangerous specific route route R2. After selection, the second navigation device starts 23 of the vehicle M, the data of the current position C2 of the vehicle M from the GPS module 21 and then starts retrieving the retrieved data with the guidance route G2 stored in the memory 25 for comparing the vehicle M to the starting point S2 along completed roads, and then the retrieved data with the corresponding specific terrain route R2 stored in the memory 25 for comparing the vehicle M from the starting point S2 to the wild-current hot-water source located at the terrain destination D;

Instead of the aforementioned Leitrouten selection process may in the memory 25 be set a selection condition, so that the second navigation device 23 can automatically select a guidance route from the three suggested routes and then display the data of the selected guidance route on the display screen. The selection condition may be based on the conditions of the shortest distance, the best traffic conditions, the risk status, the brevity of the navigation data, and so on. Receives the wireless communication module 22 proposed guidance routes, compares the second navigation device 23 of the vehicle M, alternatively, the proposed guidance routes with the selection conditions set in the memory 25 , direct, and then reserves one of the suggested guidance routes for use to direct the vehicle M to the terrain target. Therefore, the vehicle M does not have the other two suggested guidance routes in memory 25 to save.

7 Fig. 10 illustrates the system architecture of the third embodiment of the invention. This embodiment is substantially similar to the aforementioned first embodiment except for the added electronic card 24 , which is installed in the vehicle M, and in which the data of a plurality of completed roads are stored.

Therefore, the driver uses the wireless communication module 22 to provide a terrain navigation request N3 having the data of the terrain destination D to the wireless communication module 11 of the remote control center 1 when the driver desires to transmit the vehicle M from the same departure point C2 to the same wild-current hot water source located at the terrain destination D as in 6 shown to drive. Upon receiving the off-road navigation request N3, the remote control center searches 1 the terrain route database 12 and obtains three specific terrain routes R1, R2, R3 from the search, and then wirelessly transmits the search data of the three specific terrain routes R1, R2, R3 to the vehicle M, allowing the vehicle M to store the data in memory 25 save. The specific terrain routes R1, R2, R3 each have a starting point S1, S2, S3 located on a completed road. Upon receiving the proposed specific terrain routes R1, R2, R3 from the remote control center 1 Looks through the navigation device 23 of the vehicle M the completed roads in the electronic map 24 associated with the starting points S1, S2, S3 of the proposed specific terrain routes R1, R2, R3, and acquires three guidance routes G1, G2, G3 formed based on completed roads from the departure point C2 to the corresponding starting points 51 , S2, S3 of the proposed specific terrain routes R1, R2, R3, which makes it possible to display the three guidance routes G1, G2, G3 with the proposed specific terrain routes R1, R2, R3 on the display screen for selection by the driver.

In the aforementioned embodiments of the invention, the memory 25 an IC memory card that can store the aforementioned downloaded specific terrain routes, and also the contents of the provided terrain routes from the remote control center 1 can download and save what content text, graphics, moving image or voice data may have. Preferably, the off-road navigation system according to the invention may further provide the received data with the current position data of the vehicle M provided by the GPS module 21 Also, compare the surrounding scenery stored in memory 25 to display active in time.
