Abstract

PURPOSE:To obtain the guide data of a route by a simple operation by setting the guide data of each point by the input of the designation and outputting the same according to route order by a mere trigger signal. CONSTITUTION:When the destination is inputted by key input 1, guide data for going to the destination is set at every point by a guide data setting means 4. Now, when the present point is inputted as a guide point by the key input 1, guide data for going to the designation from said point is displayed on output means 5, 6. Therefore, after the designation is indicated, the guide data can be obtained from any point. After the present point is specified and inputted, the next point can be easily set as a guide point according to the guide data for going to the designation only by merely inputting a trigger signal 2.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention outputs guidance information for going to the destination at each point when a destination is input among a plurality of points set. The present invention relates to a navigation device.

[Conventional technology]

2. Description of the Related Art Navigation devices provide route guidance to destinations for drivers who are unfamiliar with geography, and navigation devices have been actively developed in recent years.

Conventional navigation devices let you set a course from the departure point to the destination before driving, and provide course guidance according to the set course. is displayed and the course is displayed overlaid on top of it. Further, when indicating the intersection to turn next according to a preset course, the distance to the intersection to turn next is displayed numerically or graphically. In such navigation devices, when turning at an intersection, the driver looks at the course displayed on the map and decides which intersection to turn next, or by looking at the numbers or graphs displayed to reach the intersection where the driver should turn. We know the distance between and determine the intersection.

[Problem that the invention seeks to solve]

However, as described above, with conventional navigation devices, a course is set in advance from the starting point to the destination before driving, and the course guidance is provided according to the set course. There is a problem in that if the vehicle deviates from the course, it is impossible to continue driving according to the guidance of the navigation device unless the vehicle returns to the set course again. In addition, whether or not you have passed through a predetermined intersection according to the course guidance is based on the premise that distance sensors and steering angle sensors are used to detect travel distance, right turns, left turns, etc. However, in reality, these detection errors may occur. Another problem is that it can easily lead to large errors in judgment.

The present invention is intended to solve the above problems, and an object of the present invention is to provide a navigation device that can output appropriate guidance information at any point without a fixed course with a simple system configuration. That is.

[Means for solving problems]

In order to achieve the above object, the navigation device of the present invention is a navigation device that outputs guidance information for going to the destination at each point when a destination is input among a plurality of points set. , a destination input means for inputting a destination from among a plurality of points, a guide point input means for inputting a guide point, and a guide for setting guide information for going to the destination for each point when a destination is input. The present invention is characterized by comprising an information setting means and an output means for outputting the guidance information set by the guidance information setting means.

[Action and effect of the invention]

In the navigation device of the present invention, when a destination is input by the destination specifying means, the guidance information setting means sets guidance information for going to the destination for each point. Therefore, when the current location is input as a guide point using the guide point input means, guide information for going from that point to the destination is displayed on the output means. Therefore, after specifying a destination, guidance information can be obtained from any location. Furthermore, after specifying and inputting the current location, simply inputting a trigger signal makes it possible to easily set the next point as a guidance point according to the guidance information for going to the destination.

〔Example〕

Examples will be described below with reference to the drawings.

FIG. 1 is a diagram showing the configuration of one embodiment of the navigation device according to the present invention, FIG. 2 is a diagram showing an example of route order, FIG. 3 is a diagram for explaining the flow of navigation processing, and FIG. FIG. 2 is a diagram for explaining route search processing.

In FIG. 1, 1 is a key manual means, 2 is a trigger manual means, 3 is a guide data storage means, 4 is a guide information setting means, 5 is a display output means, and 6 is an audio output means. The key manual means 1 consists of a numeric keypad or a funk key and can input the code number of a predetermined point such as a destination or current location (guidance location), and the trigger manual means 2 can be input from a touch switch or a push button switch. This is for inputting a single trigger signal. , guidance data storage means 3
is a memory such as a ROM that stores network data and information of each point serving as the destination and current location, and the guidance information setting means 4 uses, for example, a CPU, and the destination is input and specified by the key manual means 1. Then, information for going to the destination by route searching, for example, is set corresponding to each point stored in the guide data storage means 3, and is stored in a memory such as a RAM. Then, when the code number representing the current location is input by the key human power means 1, the display output means 5 and the audio output means 6 output the guidance information set by the guidance information setting means 4 for that point, and the trigger human power means When a trigger signal is input by 2, for example, a shown in FIG.
, b, c, . . . , the guidance information set by the guidance information setting means 4 for the next point on the route to the destination is output. For example, when only an intersection is targeted as a point, the guidance information is information for going to the destination, such as turning right or turning left at the next intersection at the intersection that is the guidance point. Also, if you turn at the next intersection and immediately approach the second intersection,
It goes without saying that instruction information such as the lane to be taken at that time may be included together with the direction of the second turn, or even the direction of the second turn may be included in the guidance information.

Next, the processing flow of the navigation device which has means for inputting a code for the destination and current location, an intersection confirmation trigger, and a current stranger's capotan, and whose guidance point is an intersection will be explained with reference to FIG.

First, when the destination code is input by the driver (step ■), the mode goes into route search mode, and the information for getting to the destination is set for all points other than the destination (step ■). When finished, the current location input mode is entered, and when the current location code is input (step ■), the direction of travel at that point is output (step ■), and the intersection V11 recognition trigger is input (start input,
Step ■) Then, output the information to go to the destination at the next intersection (Step ■) 0 Next, monitor whether the intersection confirmation trigger is activated or if the other person's capotan signal is currently activated Step ■), Intersection confirmation If a trigger is input, the process returns to step (2), and if a stranger's capotan signal is currently input, the process returns to step (2). In other words, with this system, if you are driving according to the guidance, the trigger will be manually activated each time you check an intersection, but if you notice that you have deviated from the guidance course and have driven to another intersection. Currently, someone else's capotan is pressed. Therefore,
Each time the trigger is input, guidance information for intersections on the route to the destination is output in order, but if someone else's capo button is pressed, the current location input mode is entered.

The route search process in step ■ is as follows: When entering the route search mode as shown in Figure 4 (al), first set the destination in the work area (step ■), then set the direction of travel from the intersection closest to the destination. (Step @), this direction of travel is to set the travel direction d1 for the intersection in front of the destination, and then set the travel direction d for the intersection in front of the destination, as shown in (false) in the same figure. become. This route search is
The process may be performed after the process in step (2) in FIG. 3. In this case, the route search will be performed each time the current location is input. In addition, with manual triggering, guidance information is output according to the route set as a result of route search, so the intersections that can be targeted are limited. Therefore, it may be possible to have at least the guidance information only for that intersection.

Note that the present invention is not limited to the above-mentioned embodiment, and various modifications are possible. , features such as bridges, guards, public facilities, etc. in between may be set as guide points. Also,
As the information for going to the destination, characteristic absolute information at that point may be used, and maps and photographs may be output on the display screen as well as audio. Moreover,
If there is any content that calls for particular attention in the output information,
The display mode or display attributes of that part may be changed, or a different tone color, intermittent tone, etc. may be used. Key manual means and trigger manual means do not use switches or keys.
A predetermined signal may be input by displaying menus on both sides of the display and touching the screen. Furthermore,
In addition to advancing the guide point by 1ltff using a trigger, it may also be possible to go a few points from the current location and look at the guide information and then return again.

Furthermore, instead of combining the navigation device of the present invention with a conventional device equipped with a distance sensor and a steering angle sensor, the next point P2 is determined only when the driver operates a switch (instead of using other means to identify the next point P2). It may be possible to automatically recognize a predetermined point and output guidance information.The combination of the present invention and the conventional method can be used for areas with monotonous roads such as one-way roads and areas with complex roads. The method using sensors and the method according to the present invention may be used to determine road areas, or may be used as a backup when conventional navigation devices fail.Distance between guide points It may also be possible to store information, calculate the distance using a distance sensor, and use audio or display to prompt input of instructions for the next point (manual trigger).

If you want to be able to set your favorite course, such as a back alley route or a main route, you should add information to each point as to whether it is applicable or not, and specify your preference in the guide information settings. Accordingly, the route search may be performed only at the target point.

As is clear from the above description, according to the present invention, by having the device recognize where you are, you can know what to do at that location. In other words, the guidance information for each point is set by inputting the destination, and the guidance information is output according to the route order by a simple trigger signal, so the driver can change the route by simply checking the current location and inputting the trigger. You can get guidance information. In particular, by storing all the guidance information for each point once the destination is set, there is no need to set the guidance information one by one even if the indoor point changes as long as the destination is not changed. It can reduce the burden.
