Next, processes such as route search and guidance in the present embodiment configured as described above will be described with reference to FIGS.
This will be described with reference to the flowchart of FIG.

First, basic processing from searching for a recommended route to displaying a screen will be described. First, the current position information is detected by the vehicle position detecting means 21 (step S).
1) The detection result is input to the route search means 27 and the map data drawing data conversion means 28. Further, based on the current vehicle position detected by the vehicle position detection means 21, map data within a predetermined range including the vehicle position and its surroundings is read from the map data storage means 22 by the reading means 23, Route search means 27 and map data drawing data conversion means
It is input to 28 (step S2).

Next, the map data read from the map data storage means 22 is converted into drawing data by the map data drawing data converting means 28, and the current vehicle position information is also converted into drawing data for displaying the same. Converted,
A map including the current location and its surroundings is displayed on the display means 25 (step S3).

Next, it is checked by the destination setting means 26 whether or not an operation input for setting a destination has been made by the operation means 24 (step S4), and the same check is made until the input is made ("NO"). Case).

If there is an operation input for setting the destination, the destination specified by the operation means 24 is set (step S5).

After setting the destination, the route search means 27 follows the predetermined route search program stored in a ROM or the like (not shown) built in the microcomputer and stores the destination information and the current vehicle. A process of searching for a recommended route is performed based on the position information, the link and node data, and the like (step S6).

When the result data of the search processing is output from the route search means 27 to the map data drawing data conversion means 28, the data from the current vehicle position to the destination is displayed on the map displayed on the display means 25. A recommended route is displayed as a preferable traveling route (step S7), and the current process ends.

This process is executed again a predetermined time after the end of each process, and is executed repeatedly while the navigation device is activated. Therefore, the current position displayed on the screen is sequentially changed according to the traveling position of the vehicle, and the map displayed on the screen is scrolled substantially in the traveling direction.

In this state, or before the actual traveling after the destination is set, when the user performs a predetermined operation on the operation means 24 and gives an instruction to start a route guidance demonstration, a pseudo traveling as shown in FIG. Section setting processing is executed. Here, a description will be given assuming that a pseudo traveling section is set by designating a start point or an end point of the pseudo traveling.

In FIG. 3, when a start instruction of the route guidance demonstration is given, first, default setting is made such that the start position of the pseudo run is the own vehicle position and the end position is the latest destination (step S11). Once set up, ask the user to run the "Driving Demo for All Routes"
Two options as to whether to specify the demonstration start / end position are displayed on the display means 25, and the user is prompted to select one of them (step S12).

At this time, when [guidance demonstration of all routes] is selected by the operating means 24, the current position display mark is displayed on the screen with the demonstration start position as the own vehicle position and the demonstration end position as the destination. The simulated traveling to be started is started in the same manner as the conventional route simulation, and a route guidance demonstration is performed for the entire recommended route (step S13).

On the other hand, when the "designation of demonstration start / end position" is selected, information such as road information (for example, expressways, national roads, general roads, etc.) and expressway interchanges (ICs) in the link order of the search results. Are rearranged, and route information as shown in FIG. 4 is created. Based on the route information, a display for allowing the user to select and determine a start point or an end point is executed by the display means 25.

That is, the recommended route from the current position of the vehicle to the destination is divided into a plurality of traveling sections according to the type of each road in the route, with the link included in the map data as the minimum unit. Is generated (step S14), and a route Rs including a plurality of traveling sections r1, r2, r3, and r4 is displayed on the screen of the display means 25, for example, as shown in FIG.

In this state, a plurality of travel sections (for example, travel sections r1 to r4) displayed on the screen of the display means 25 are provided.
Among them, the operation section 24 performs an operation input for selecting a traveling section where the simulated traveling is to be started or ended (a position corresponding to the start point or the ending point), and the simulated traveling section can be set.

Here, when the start position of the route guidance demonstration by the simulated traveling is set by the user, the starting position is registered as the starting point of the simulated traveling. Further, when the end position of the route guidance demonstration by the pseudo traveling is set by the user, the end position is registered as the end point of the pseudo traveling. And
When the start position is registered, the vehicle position information is temporarily moved to the start point of the pseudo traveling, and when the end position is registered, the end point of the pseudo traveling is set to a destination other than the destination.

After the registration of the start / end positions, when the user instructs to confirm the operation input information by the operation means 24, the setting is completed.

Then, in the set pseudo running section, a route guidance demonstration by the pseudo running in step S13 is executed. That is, the route guidance demonstration starts at the designated start point, and ends at the designated end point.

As described above, the process of the current route guidance demonstration is completed.

According to the present embodiment, since the start / end position setting means 29 for designating the start point or the end point of the pseudo run in the route guidance demonstration is provided, the vicinity of the user's home or other well-known routes is provided. A section can be set to omit the route guidance demonstration for. Therefore, by performing route guidance using only the information necessary to reach the destination, the time required for the route guidance demonstration can be significantly reduced, and the user can quickly and accurately grasp the route to the destination. it can.

As described above, in the present embodiment, the simulated travel section for the route guidance demonstration is variably set in accordance with the operation input for designating the start point or the end point of the simulated travel. Quick and accurate route guidance can be performed by designating only a suitable section.

In the above description, in order to designate a point at which route guidance is started or ended, route information including a group of links as shown in FIG. 4 is displayed on the display means, and the user selects a start or end link. However, it is needless to say that the point to be designated is displayed by, for example, moving the display center coordinates of the map on which the route is displayed by the operation means, and the start and end points are selected. The same method can be implemented.
The operation input for setting the section is not limited to specifying the start and end points, but may be specifying the waypoint. Alternatively, the pseudo travel distance from the specified point may be set to specify the section (range ) Itself may be specified. In addition, a pseudo road may be specified by specifying an arbitrary road section or area irrespective of the current vehicle position (travel position) or the destination. Further, the operation input is, for example, an operation input by a manual operation, but may be an input by not only a manual operation but also a voice operation using voice recognition.

In the following, other embodiments will be described. In each embodiment, a predetermined mark representing a traveling position on a map displayed on a screen is simulated without being linked to the own vehicle position and designated. A navigation device having a demonstration function of performing a route guidance by simulated traveling of a section that has been provided, each including a simulated traveling section setting unit that variably sets a simulated traveling section for the route guidance according to an operation input; The minimum information required to reach the destination in a short time is obtained.

[Second Embodiment] FIG. 5 is a flowchart showing a speed change process in a route guidance demonstration of a navigation device according to a second embodiment of the present invention. The system configuration of the present embodiment is almost the same as that of the first embodiment. Therefore, the same or corresponding components will be described using the same reference numerals as those in FIG. 1, and the description will be repeated. Is omitted.

The navigation apparatus according to the present embodiment adds a function of requesting a change in the pseudo traveling speed to the operation means 24, and stores a processing program for changing the pseudo traveling speed in the route guidance means 30 and the pseudo traveling means 31. Provided.

Further, the processing procedure of the route guidance demonstration in the navigation device of the present embodiment is as follows. After detecting the current position information, the map data is read out, the necessary map is drawn on the display screen, and the destination is set. The first embodiment is similar to the first embodiment in that the recommended route is searched and displayed on a map, and a start point and an end point are set when a route guidance demonstration by simulated traveling is performed.

The process of the route guidance demonstration in this navigation device is characterized by a guidance speed change process as shown in FIG. 5 after the route guidance demonstration has been started from the above-mentioned starting point.

As shown in the figure, when the route guidance demonstration by the simulated traveling in the simulated traveling set section is started in the same manner as in the above-described embodiment, first, the end point of the route guidance (the simulated traveling section) is set. It is checked whether it has reached (step S21).

At this time, if the end point has not been reached (in the case of "NO"), it is checked whether there is a request to change the guide speed (step S22). That is, it is determined whether or not the user has requested a change in the pseudo traveling speed using the operation unit 24 before the pseudo traveling reaches the end point of the route guidance demonstration.

If there is no request to change the guide speed, the process returns to step S21 to check again whether the vehicle has reached the end point.

On the other hand, if there is a request to change the guide speed, the process proceeds to the next step S22, where the process of changing the guide speed, that is, changing the pseudo running speed is executed (step S2).
3). This speed change process changes the simulated traveling speed in a range in which route guidance can be effectively performed (a speed range that does not exceed an upper limit speed that is possible due to drawing processing and is equal to or higher than a lower limit speed during actual route guidance). It is.

When the speed change in step S23 is completed,
Returning to step S21, it is checked whether the vehicle has reached the end point again. When the vehicle reaches the end point ("YES"), the current route guidance demonstration ends.

As described above, according to the present embodiment, by increasing the pseudo traveling speed during the route guidance demonstration, a route guidance demonstration that the user finds redundant when a route without an intersection that turns right or left continues for a long time, or the like. It can be seen that the vehicle is fast-forwarding, and by reducing the simulated traveling speed, the user can calm down and see the route guidance demonstration at a complicated intersection or around an interchange on an unclear expressway.

[Third Embodiment] FIG. 6 is a flowchart showing the process of changing the scale and the guidance speed in the route guidance demonstration of the navigation device according to the third embodiment of the present invention. Note that the system configuration of this embodiment is almost the same as that of the first embodiment.
The same or corresponding components will be described using the same reference numerals as in FIG. 1, and redundant description will be omitted.

In the navigation device of the present embodiment, the function of the distance determining means for determining the distance to the next intersection where the vehicle turns right and left is added to the route guidance means 30 and the pseudo running means 31, and based on the determination result. A processing program is provided for changing the scale of the map to be displayed on the screen and the simulated traveling speed for some traveling sections. That is, the route guidance means 30 and the pseudo traveling means 31 are provided with the function of a scale variable means capable of changing the scale of the map display of the pseudo traveling section. Further, when scrolling the map displayed on the display screen along with the simulated traveling, the route guidance means 30 and the simulated traveling means 31 perform the scrolling speed of the map when there is an intersection that turns right and left around the simulated traveling position. Further, a function of increasing the scroll speed of the map when there is no intersection that turns right or left around the pseudo traveling position is provided.

Further, the processing procedure of the route guidance demonstration in the navigation device of the present embodiment is as follows. After detecting the current position information, the map data is read out, the necessary map is drawn on the display screen, and the destination is set. The first embodiment is similar to the first embodiment in that the recommended route is searched and displayed on a map, and a start point and an end point are set when a route guidance demonstration by simulated traveling is performed.

The process of the route guidance demonstration in this navigation device is characterized by a process of changing the scale and the guidance speed as shown in FIG. 6 after the route guidance demonstration is started from the above-mentioned starting point.

As shown in the figure, when the route guidance demonstration by the simulated traveling for the simulated traveling set section is started in the same manner as in the above-described embodiment, first, the end point of the route guidance (the simulated traveling section) is determined. It is checked whether it has reached (step S31).

At this time, if the vehicle has not reached the end point (in the case of "NO"), it is checked whether or not the distance from the current vehicle position to the next intersection where the vehicle turns right or left is 500 m or more (step). S32). That is, it is determined whether or not the pseudo traveling position is sufficiently away from the intersection where the vehicle turns left or right.

If the result of the determination is "YES", it is determined that the pseudo traveling position is sufficiently far from the intersection, and in the next step S33, the scale of the map displayed on the display means 24 is reduced to provide a wide field of view. Is provided, the pseudo traveling speed is increased (step S34), and the process returns to step S31.

If the decision result in the step S32 is "NO", it is determined that the pseudo traveling position is approaching the intersection, and in a next step S35, the scale of the map displayed on the display means 24 is increased. After displaying the detailed map around the intersection, the pseudo traveling speed is reduced (step S36).
Return to S31.

If the decision result in the step S35 is "NO", it is determined that the pseudo traveling position has approached to some extent, and in the next step S35, the scale of the map displayed on the display means 24 is reduced to a predetermined normal size. After returning to the scale (step S3
8), the pseudo traveling speed is returned to the predetermined normal speed (step S39), and the process returns to step S31.

When the flow returns to step S21 from any of steps S34, S37 and S39, it is checked again whether or not the end point has been reached. When the end point has been reached (in the case of "YES"), the present route guidance demonstration is performed. Ends.

As described above, according to the present embodiment, when the distance to the next intersection where the vehicle turns left or right is 500 m or more, the scale of the map is reduced to display a wide area map and the pseudo traveling speed is increased. On the other hand, the distance to the intersection where you turn
If the distance is less than 50m, increase the map scale to display a detailed map around the intersection and slow down the pseudo-running speed.If the distance to the intersection is not one of the above, use the normal map scale or normal pseudo-scale. Set the running speed.

Therefore, according to the present embodiment, when there is no long-distance intersection on the route over a long distance (highway, suburb, etc.), the route guidance demonstration can be viewed as fast-forwarding, The information around the intersection can be seen in detail. That is, only important information can be obtained in a short time as compared with the conventional route simulation.

[Fourth Embodiment] FIG. 7 is a flowchart showing a travel section setting process in a route guidance demonstration of a navigation device according to a fourth embodiment of the present invention, and FIG.
And the guidance omission range of a certain distance (radius) centered on this,
FIG. 7 is a diagram illustrating a relationship between route guidance demonstration ranges set outside the guidance omission range. The system configuration of the present embodiment is almost the same as that of the first embodiment. Therefore, the same or corresponding components will be described using the same reference numerals as those in FIG. 1, and the description will be repeated. Is omitted.

The navigation apparatus according to the present embodiment adds a function of designating a point P which is a reference of an omission range when setting a pseudo traveling section to the operation means 24, and also adds to the route guidance means 30 and the pseudo traveling means 31 , The route Rs searched within a certain distance from the vehicle position, the destination or the designated point
A processing program is provided for determining whether or not a part of the route exists, and partially setting and omitting the start and end positions of the route guidance by the simulated traveling based on the determination result. The point P serving as a reference for the omitted range is the recommended route R
designated as any point relatively close to part of s,
Information for determining a specific section for which route guidance is unnecessary is stored in a built-in memory (specific section storage means) of the microcomputer constituting the route guidance means 30 and the pseudo running means 31. In addition, the route guidance means 30 and the simulated traveling means 31 as simulated traveling section setting means set the starting point or the ending point of the simulated traveling outside the specific section.

The processing procedure of the route guidance demonstration in the navigation apparatus according to the present embodiment is such that after the current position information is detected, the map data is read out and the necessary map is drawn on the display screen, and the recommendation to the set destination is made. The first embodiment is similar to the first embodiment in that a route is searched and displayed on a map, and a start point, an end point, and the like are set when a route guidance demonstration by simulated traveling is performed.

The route guidance demonstration processing in this navigation device is characterized by a guide section (pseudo travel section) setting process as shown in FIG. 7 after the route guidance demonstration is instructed by the operation means 24.

First, in the present embodiment, after a route guidance demonstration is instructed, when a point serving as a reference for setting an omission range of a pseudo-running section is designated as an arbitrary point by using the operating means 24, A process for omitting the route guidance demonstration is executed around the set point, and if no such point is specified, the same process as in the first embodiment is performed. Therefore, a case in which an arbitrary guidance omission point is designated using the operation means 24 will be described.

When an arbitrary guide omission point is designated by using the operation means 24, first, as shown in FIG.
Then, it is determined whether or not there is a route searched within a certain distance from the guidance omission point arbitrarily set by the user (step S41).

If there is no route searched, the start position is set to the current vehicle position and the end position is set to the destination so as to perform the above-mentioned "guidance demonstration of all routes" (step S42). Then, a route guidance demonstration according to the setting is executed (step S43).

If the decision result in the step S41 is "NO", then, as shown in FIG. 8 (a), it is determined whether or not the own vehicle position is within a certain distance from a point designated by the user. It is determined in S44, and the determination result is “YES”
If so, the intersection A of the circle with a certain radius from the designated point and the recommended route searched for is set as the start position of the pseudo run (route guidance demonstration), and the destination is set as the end position of the pseudo run (step S45, S4
6) Then, a route guidance demonstration according to the setting is executed (step S43).

If the decision result in the step S44 is "NO", it is decided in a step S47 whether or not the destination is within a certain distance from the point designated by the user as shown in FIG. 8B. If the determination result is “YES”, the own vehicle position is set as the start position of the pseudo traveling (route guidance demonstration), and the intersection B of the circle having a constant radius from the designated point and the searched recommended route is pseudo. The travel end position is set (steps S48 and S49), and then a route guidance demonstration according to the setting is executed (step S43).

If the decision result in the step S44 is "NO", as shown in FIG. 8C, a part of the recommended route searched is within a certain distance (radius) from a point arbitrarily set by the user. Then, the start position of the pseudo run (route guidance demonstration) is set as the current vehicle position, the end position is set as the destination, and a circle with a fixed radius is searched from the point specified by the user. A high-speed scroll section is set between the intersections C and D of the route (step S52), and a route guidance demonstration according to the setting is executed (step S43).

As described above, in the present embodiment, when the user's own vehicle position or destination is within a certain distance radius from the point P designated by the user as an unnecessary point for guidance, a route guidance demonstration by simulated traveling is performed. The start / end position of the is set as the start point or end point of the range where guidance is required (outside the range of the specific section), and a part of the recommended route ( If there is a specific section, the scroll speed of the map on the screen is increased so as to fast-forward the section.

Therefore, according to the present embodiment, for example, when the point P arbitrarily set by the user is the user's home, the route guidance demonstration around the home is not performed. Route guidance around your home is unnecessary. That is, the route guidance demonstration which is unnecessary for the user can be omitted, and only the necessary information can be obtained in a short time, which is superior to the conventional one.

In the above description, the method of setting the start and end points of the route guidance demonstration at a position separated by a predetermined distance from the point arbitrarily set by the user has been described. A method of referring to the recorded past road running history and setting a point where the route guidance demonstration starts and ends at a position separated by a certain distance from the road on which the vehicle has traveled is also effective. That is, the means for storing the specific section may store information on the road on which the vehicle has traveled, and may set the specific section based on the stored information.

It is also conceivable that the user not only sets a section where guidance is unnecessary, but also designates an arbitrary point only for a section where detailed guidance is required.

In each of the above embodiments,
Although described as an in-vehicle navigation device mounted on an automobile, it goes without saying that the navigation device of the present invention can be used for other vehicles or moving objects traveling on the ground.
