13) When the reverse course button 34 is turned on (step S14), the guide operation starts after setting the reverse course and executing the route calculation (step S14).
15).

(2) Description of Route Calculation Process Next, the process of calculating a route based on the drive course set as described above will be described with reference to the flowchart of the route calculation program in FIG. First, the control circuit 1 reads the data of the drive course set from the disk (step T1), and sets the end point position of the read course information as a temporary destination (step T2).

Thereafter, the control circuit 1 calculates a route from the data of the current position, the passing point data and the data of the temporary destination (step T3). As a result, the route from the current location to the end point of the selected drive course is calculated. Thereafter, the route data as a result of the calculation is stored in the memory 5, and the route data is set to be used for subsequent route guidance (step T4), and waits for the guidance start button to be turned on.

(3) Description of Route Guidance Operation When the route is calculated as described above, the control circuit 1 displays a route guidance display screen 45 as shown in FIG. In this display screen 45, the part of the drive course 47 of the map display part 46 is displayed with a thick line so that it can be easily recognized, and the points of interest are numbered in diamonds in order from the entrance side of the course. Is displayed,
The end point of the course is indicated by a G symbol in a mark that fits. At the lower left of the screen, a "guidance" button 48 is displayed. In addition, as a display unit necessary for navigation,
A direction and scale display 49, an estimated arrival time display 50,
A display section 51 for the distance to the surroundings, a display section 52 for the road information and the number of distances for all the trips, a button 53 for “route information”,
A "Details" button 54, a "Wide area" button 55, and the like are displayed.

Here, when the "guidance" button 48 is turned on by the user, the control circuit 1 starts the route guidance program shown in FIG. 7 and simultaneously activates the button 48 indicating "guidance". The menu is switched to the button 48a (see FIG. 15) and displayed. This is to turn on when viewing the various screens displayed when the above-described drive course selection operation is performed during the route guidance operation.

Now, when the route guidance program is started,
The control circuit 1 executes a normal route guidance operation until it comes near the entrance of the set drive course (step P).
1, P2). As a result, the route from the current location to the entrance of the drive course is guided by normal route guidance. Then, when the vehicle comes near the entrance of the drive course (step P2), the control circuit 1 provides voice guidance explaining the outline of the course, for example, "I will enter the drive course soon. This drive course is ...". (Step P3).

In the following route guidance, the control circuit 1
Until approaching to the highlight, route guidance of the drive course is executed by voice guidance according to the bus guide information read from the disk (steps P4 and P4).
5). Then, when detecting that the highlight is approaching (step P4), the control circuit 1 starts voice guidance of the highlight information (step P7). At this time, the control circuit 1 displays, for example, on the display screen 56 as shown in FIG.

On the display screen 56, the control circuit 1
Is used to indicate that you are close to the highlights, for example,
At the same time, a message 57 such as "It is around Kurhaus Shirakawa-go" is displayed. On the display screen 56,
An "information" button 58 for displaying the highlight information is displayed. When this button 58 is turned on (step P8), the control circuit 1 causes the above-described highlight information display screen 42 (see FIG. 13). Will be displayed. When the "return" button 20 is turned on (step P1)
0), the display returns to the route guidance display screen 45 (see FIG. 14), and the voice guidance of the drive course is continued (steps P4 to P6).

Thereafter, while the above process is repeatedly executed, when the end point of the drive course is approached, the control circuit 1
Determines that the drive course has ended (step P6), and provides voice guidance of the end of the drive course (step P11). Here, for example, if necessary, a sound such as "How was this drive course?" Is notified and the route guidance of the drive course ends. If the destination is set separately, the process returns to the normal route guidance operation and performs route guidance until reaching the destination.

As described above, in this embodiment, information on a large number of drive courses is stored as course information on a disc as a course information recording medium such as a DVD-ROM or a CD-ROM, and is read and used. When a user selects and sets a desired drive course, a route for traveling on the selected drive course from the current location can be automatically set.

Thus, even when the user does not know much of the information on the sightseeing spots, a route including a drive course including sightseeing spots can be accurately and simply by selecting from various displayed drive courses. Be able to set up quickly.

Further, the user can set a route only by selecting a drive course without setting a so-called destination, and can also perform route guidance, so that usability is improved.

Since the course information is stored as data having a hierarchical structure, the displayed screen is switched by sequentially operating the buttons to select a desired drive course and provide route guidance. The setting operation can be performed easily, so that an inexperienced user can easily use the setting operation, and even a used user can quickly perform the setting operation.

The present invention is not limited to the above embodiment, but can be modified or expanded as follows. If the current position is within the display range of the course illustration,
The current position can be displayed on the display screen of the course illustration. The route display of the drive course can be displayed in an easily understandable color and line type different from the normal route leading to the route.

It is possible to set a destination other than the drive course separately after selecting the drive course, and set a route via the selected drive course for the destination set by the user. You can make it. Conversely, a destination can be set in the drive course. In this case, the route can be calculated by recognizing the destination as a passing point in the drive course, or the route from the entrance in the forward or reverse direction to the destination via the passing point can be calculated. You may make it handle as a target range.

It is also possible to increase or decrease the number of passing points in the set driving course. In this case, it is possible to flexibly cope with the route calculation by adding or deleting the place to be passed as the passing point information and setting it. In the course setting in the forward direction or the backward direction, the predetermined direction is set as the forward direction, but the display direction may be determined by determining the direction going from the near entrance side based on the current position as the forward direction. Further, in the setting of the forward direction or the reverse direction, the setting can be made in consideration of the one-way traffic on the road and the traffic direction according to the restriction of the road sign.

Information such as the weather and the traveling direction of a car can also be used as a criterion in highlight guidance. In addition, the route may be set in consideration of not only data from the course information recording medium but also road information obtained from VICS or the like. Further, it is also possible to configure such that the course information is acquired as information from a communication network such as the Internet and a desired course is selected to set a route.

During the route guidance of the drive course,
It is also possible to provide a function that mainly provides voice guidance and sets the data display guidance so that the driver cannot view the data while driving. In addition to sightseeing drive courses, the present invention can be applied to setting of traveling courses and patrol courses according to uses such as various tours, company visits, and museum tours. The description of the course information can use a language or a format other than the language of the HTML format.

In addition to the vehicle navigation device, the present invention can be applied to a route setting device that is carried when walking or the like. When the driver leaves the drive course halfway, a reroute calculation that can smoothly return to the drive course thereafter is performed, so that guidance to the drive course can be performed.
