Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation device for searching for and guiding a guidance route for a vehicle and a route guidance method therefor.

[0002]

2. Description of the Related Art In a conventional navigation device and a route guidance method for guiding a guide route of a vehicle, a destination set by a user and a current position of the vehicle detected by a GPS (Global Positioning System) or the like are used. The guide route to travel is searched for from the map information storage means such as a CD-ROM and displayed. When you make a right turn (or a left turn) at an intersection, you will hear a voice saying, "It's XX kilometers to the intersection." It is configured to clearly notify that an image showing an intersection is to be turned right with an arrow mark or the like.

[0003]

Since the conventional navigation device and the route guidance method therefor are configured as described above, the navigation device and the route guidance method thereof are determined in advance regardless of the driving skill and personality of the driver who is the user. The guidance information is notified by a voice message, and an image of a predetermined shape is displayed regardless of the actual shape of the intersection. For this reason, users with high driving skill and speedy personality have been dissatisfied with the notification of intersections being too early or the number of notifications being too large. On the other hand, for users with low driving skill and those with a cautious personality, there were complaints that the notification of intersections was too slow and the number of notifications was too small. Further, when the shape of the actual intersection is different from the displayed image of the intersection, there is a possibility that the direction of right turn or left turn may not be recognized. For example, when the running main line is curved along the road, even if the user tries to “go straight” along the road, a voice message for right turn or left turn is displayed, or the curve of the main line is displayed. Since it is drawn as a straight line, there is a risk that the road that turns right or left may be mistaken. As described above, the conventional navigation device and the route guidance method thereof always output constant guidance information irrespective of the user's individuality and the shape of the actual intersection, so that a reasonable and safe route guidance adapted to the user is provided. There was a problem that I could not do it. Such a problem was not limited to intersections, but also to specific target points in the searched guide route such as curves and railroad crossings.

The present invention has been made to solve the above problems, and a navigation device and a route guide for realizing a reasonable and safe route guide in consideration of the individuality of the user and the shape of the actual target point. Aim to get a way.

FIG. 2 shows a guide target point change information storage means 9
3 shows a data format showing a configuration of target point information stored in FIG. Target point information is classified into intersections, curves, railroad crossings, and the like. Then, each target point information is classified into a plurality of types of records, that is, stored data.
For example, the intersection information is classified into a plurality of types of intersection records corresponding to the shape. Furthermore, each intersection record is classified into a plurality of user IDs. As shown in the figure, the intersection record of each user ID is composed of a plurality of attributes such as a mesh code, an inflow link ID and the like. The standard intersection record is stored in advance in the memory of the guide information generating means 8.

Next, each attribute will be described. The mesh code is data that divides the map information into certain sections and identifies the sections. The inflow link ID is data for identifying a road entering the intersection. The inflow link route type is data for identifying the type of road of the inflow link (highway, national road, prefectural road, city road, etc.). The inflow link lane number and the inflow link road width are data indicating the lane and the lane width of the inflow link, respectively. The outflow link ID is data that identifies a road exiting from the intersection. Each data of the outflow link route type, the outflow link lane number, and the outflow link road width has the same attributes as the data in the case of the inflow link. The link ID is a unique value within one mesh code. The connection angle is data that sets the intersection angle between the inflow link and the intersecting link. The cost is data indicating a cost value under conditions such as time priority, distance priority, toll road charge priority, and general road priority. The presence / absence of guidance is data for setting whether to output guidance information. The distance is data that sets a start distance for performing voice guidance. The guidance count is data that sets the number of voice messages.

Next, the operation will be described. 3 to 5
6 is a flowchart showing the operation of the route guidance method of the navigation device in FIG. 1, and FIGS. 6 to 12 are diagrams showing images of the route guidance method displayed on the display / voice output means 5. In the flow of FIG. 3, first, a menu screen is displayed (step ST101). FIG. 6 shows the menu screen. As shown in this figure, an icon for selecting the standard guide and the user-specified custom guide and an OK icon for confirming the selection are displayed. Next, it is determined whether or not the custom guidance is designated by the operation of the operation means 3 (step ST102). When the custom guidance is not designated, it is determined whether or not the standard guidance is designated (step ST103). Since the procedure of selection by the operation means 3 and the change of the display form of the icon are well known methods, the description thereof will be omitted.

When standard guidance is designated, standard intersection guidance is set (step ST104). And
It is determined whether or not the guidance is started (step ST105), and when the guidance is started, the intersection guidance information which is the default data stored in advance in the memory of the guidance information generating means 8 is read (step ST106), and the default guidance is set. An intersection guide map is displayed (step ST107), and a default intersection voice guidance is output (step ST).
108). Next, it is determined whether or not the vehicle has arrived at the destination (step ST109), and if it has not arrived, the processes from step ST106 to step ST109 are repeated. When the vehicle arrives at the destination, the process proceeds to step ST101 and the menu screen is displayed in preparation for a new route search.

When custom guidance is instructed in step ST102, a user ID input screen is displayed (step ST110). FIG. 7 shows a user ID input screen. Then, it is determined whether or not the user ID is input (step ST111). The user ID is composed of, for example, several digits. When the user ID is entered,
Authenticating that ID and registering that ID previously registered
It is determined whether or not it is D (step ST112). That is, it is determined whether or not it matches the specific user ID shown in FIG. If it is a registration ID, the intersection guidance corresponding to the ID is read (step ST113).
If it is not the registration ID, the input user ID is registered (step ST114). After this, as shown in FIG. 8, a screen for selecting a guidance target point to be changed to user specifications is displayed. The number of guiding points to be changed may be one or more. Here, it is assumed that the guide information of the intersection has been selected to be changed to user specifications.

Next, in the flow of FIG. 4, it is judged whether or not the guidance is started (step ST115). When the guidance is started, the intersection guidance corresponding to the user ID is read (step ST116), and it is determined whether or not it applies to the already set content, that is, the content changed by the user (step ST117). If this is the case, display the intersection guide map after changing the settings (step ST
118), and the intersection voice guidance after the setting change is output (step ST119).

If the set contents are not applicable, the default intersection guide map is displayed (step ST
120), and outputs the default intersection voice guidance (step ST121). Therefore, the input user I
If D is a newly registered ID instead of a registered ID, all intersections (as well as curves and railroad crossings) display default intersection guidance maps and output default intersection voice guidance. Become. After step ST119 or step ST121, a message for selecting the method of intersection guidance and whether or not it is necessary is sent (step ST1).
22). That is, as shown in FIG. 9, the searched intersection is displayed, and the “change” and “unchange” icons are displayed, and the operating means 3 is used to select one of them. Alternatively, at the time of intersection guidance, a confirmation message such as "Press the A key to change the guidance at this intersection, or press the B key if you do not want to change it." The user presses the A key or the B key of the operation means 3 in accordance with this message.

Then, it is determined whether or not a predetermined time has elapsed from the message sending instruction (step ST123).
That is, it is determined whether or not a predetermined time has passed after the guided intersection. If the predetermined time has not elapsed, it is first determined whether or not "change" is selected (step ST124). If "change" is not selected, it is determined whether "no change" is selected (step ST12).
5). When "no change" is selected, the no change information is stored in the memory of the guide information generating means 8 (step ST126), the process proceeds to step ST116, and the next intersection guidance is read. If neither "change" nor "no change" is selected, it is determined in step ST123 whether or not a predetermined time has elapsed. When the predetermined time has passed,
Assuming that "no change" has been selected, step ST
The process proceeds to 116 and the next intersection guidance is read. At this time, if the confirmation message is displayed, the confirmation message is deleted.

If "change" is selected in step ST124, any one of the display shape, the guidance voice, the guidance start distance, and the number of guidance is determined as the setting content to be changed in the flow of FIG. 5 (step ST127). ).
In this case, a plurality of items such as the display shape of the intersection, the guidance voice, the start distance, and the number of times of guidance are sequentially displayed, and the item to be changed is selected by operating the enter key. Alternatively, as shown in FIG. 10, the display shape of the intersection, the guidance voice, the start distance,
A plurality of items of guidance frequency are displayed at one time, and the item to be changed is selected by operating the enter key while shifting the cursor position (for example, reverse display) for each item in order.

For example, if the actual shape of the guided intersection is different from the displayed shape, the user will change the display shape of the intersection to the actual shape. A shape that displays the actual shape of the intersection (for example, a cross shape)
Instead, when the main line is curved, the display shape is selected from the guidance target point change information storage means 9 according to the operation of the operation means 3 by the user. Then, a message for confirming the selected settings is sent (step S
T128). That is, as shown in FIG. 11, the changed shape of the intersection is displayed and “OK” and “N” are displayed.
Display the G "icon.

Alternatively, when changing the starting distance of the guided intersection, the guiding start distance is determined. In this case, as shown in FIG. 12, a screen for changing the guide start distance is displayed, the numerical value of the guide start distance is changed in response to data input from the operation means 3, and "OK" and "" are displayed as confirmation messages. Display the NG "icon.

Alternatively, when changing the voice guidance of the guided intersection, the voice guidance is displayed in text format and the voice guidance text is changed according to the operation of the operating means 3. For example, the voice guidance of "Turn right" is changed to "Curve to the right along the road." Then, the icons of "OK" and "NG" are displayed as a confirmation message.

Next, it is determined whether or not "OK" is selected (step ST129). If "OK" is not selected, then it is determined whether or not "NG" is selected (step ST1).
30). If "NG" is selected, step ST
The process moves to 127 and the setting contents to be changed again are displayed.
When "OK" is selected, it is determined whether or not the setting contents to be changed are reflected not only at the current intersection but also at all intersections throughout the country (step ST131).

When it is instructed to reflect on the whole country, the intersection information reflected on the whole country is stored in the memory of the guide information generating means 8 (step ST132). If no instruction is given to reflect the information nationwide, individual intersection information (specific target point information) is stored in the memory of the guide information generating means 8 (step ST133). After storing the intersection information or individual intersection information reflected in the whole country, it is determined whether or not the destination is reached (step ST134). If it has not arrived, the process proceeds to step ST116 of FIG. 4, the next intersection guidance is read, and the subsequent steps are executed. When the destination is reached, step ST1 in FIG.
The process moves to 01 and the menu screen is displayed in preparation for a new route search. Therefore, after changing the intersection information,
Next, when a guidance route that passes through the same intersection is searched for, user-specified intersection guidance is executed.

As described above, according to the first embodiment,
When the display change instruction information is input by the user, the guide information generated based on the intersection information selected according to the display change instruction information from the stored plural kinds of user-specified intersection information is displayed. Since the information is output, it is possible to obtain a rational and safe route guidance by using the image guidance information and the voice guidance information in consideration of the user's individuality and the shape of the actual intersection.

Further, according to the first embodiment, since at least one of the image guidance information and the voice guidance information at the searched intersection is generated as the guidance information, the individuality of the user and the actual shape of the intersection are taken into consideration. The image guidance information and the voice guidance information have the effect of realizing rational and safe route guidance.

Further, according to the first embodiment, guidance information indicating presence / absence of guidance at the searched intersection, guidance content, guidance timing, or guidance frequency information, or a combination of a plurality of these guidances. Since the information is generated, it is possible to obtain rational and safe route guidance by providing detailed guidance information in consideration of the individuality of the user and the actual shape of the intersection.

Further, according to the first embodiment, since the guidance information at the searched intersection is created for each intersection, it is rational and safe in consideration of the shape of the actual intersection selected by the user. The effect that route guidance can be realized is obtained.

Further, according to the first embodiment, since the guidance information at any searched intersection is created and the guidance information at another intersection is created in consideration of the attribute of the desired intersection, the search is performed. When the guide information of one intersection is changed, the effect that the guide information of all other intersections having the same attribute as the intersection can be automatically changed in a batch is obtained.

Further, according to the first embodiment, the guide information at the searched intersection is generated based on the user-specified target point information selected according to the user ID, so that the individual vehicles using the same vehicle can be generated. It is possible to obtain a rational and safe route guidance in consideration of the actual shape of the target point for each user.

Since a plurality of users are assumed in the first embodiment, the user ID input screen is displayed in step ST110 of FIG. 3 to prompt the input of a single user's user ID. It is possible that there is only one user who uses the navigation device.
In this case, if one user is set in advance as the initial value, it is not necessary to input the user ID each time the navigation device is activated. In such a case, when the custom guidance is designated in step ST102 of FIG. 3, the process proceeds to step ST115 of FIG. 4 and it is determined whether or not the guidance is started. Therefore, it is possible to obtain the effect of reducing the burden on the user due to the operation.

Further, in the above-mentioned first embodiment, FIG.
In step ST127, the items to be changed are displayed in order, or all items are displayed and designated by sequentially shifting the cursor by moving the cursor. However, "display shape change", "guidance voice change", "start distance" The icons of "change", "change number of times of guidance", and "change all" may be displayed and arbitrarily selected by the user operating the cursor keys.

Further, in the above-described first embodiment, the change of the intersection guidance has been described, but the guidance of another guidance target point such as a curve or railroad crossing may be changed.
For example, regarding the setting of curve guidance, it is possible to set whether or not to display the curve guide map, and in the voice guidance, in addition to the message "It is a curve.", "It is a corner."
Alternatively, it may be configured to be able to select from a plurality of voice guidances, such as "Hairpin curve." In addition, since it is necessary to decelerate in advance for a curve having a steep angle, the guide information may be output early. Conversely, in the case of a gentle curve, the guide information may not be output. Since there are individual differences in such settings, by setting changes in user specifications, similar to the case of intersections, rational and safe route guidance considering the user's individuality and the shape of the actual guidance target point can be provided. The effect that it can be realized is obtained.

Further, in the above-mentioned first embodiment, FIG.
In step ST123, it is determined whether or not a predetermined time has elapsed from the message sending instruction, and the guidance information is changed if a change instruction is given before the predetermined time elapses. That is, although the guide information is changed while the vehicle is traveling, the guide information may be changed after the vehicle is traveling. In this case,
After arriving at the destination, the guidance route to the destination is searched again, the guidance target point on the guidance route is searched, and the guidance information of the searched guidance target point is changed. In this case, since the vehicle is not traveling, it is possible to calmly change the setting content.
