[Problems to be solved by the invention]
In Patent Literature 1, since a section for performing guidance on a route is set in advance, information when a traffic obstacle or the like occurs due to a dynamic factor (VICS (registered trademark) or the like) in a guidance prohibited section can be obtained. Congestion, regulations, etc. cannot be avoided. In addition, a section that does not require guidance must be set every time.
[0007]
Also in Patent Document 2, since the user operates the voice output switch to perform route guidance by voice, it is impossible to obtain information when a traffic obstacle or the like occurs unless the user operates the voice output switch. The switch operation must be set each time guidance is required.
[0008]
Also in Patent Document 3, it is not possible to obtain information when a traffic obstacle occurs due to a dynamic factor (VICS or the like) in a guidance-prohibited section, it is not possible to avoid congestion or regulation, and very little from a non-guide point. There are inconveniences such as guidance being provided even at a displaced point.

[0012]
FIG. 2 is a diagram illustrating an example in which a guidance prohibited area is within a predetermined radius from a set point.
The guidance-prohibited area is set to be within the range of the set distance Lm with the set point coordinates (east longitude, north latitude) as the center. In this range, in one embodiment, when the route is set, the guidance is not automatically output regardless of the case where the route is not set, and the dynamic information (VICS (registered trademark)) is not output. Etc.) or when there is a request from the user, guidance is provided, and otherwise guidance is not provided. By doing so, it is possible to eliminate the hassle caused by always providing guidance and to cope with a case where the user wants to listen to music or the like. In addition, when setting a guidance prohibition area, it can be set by determining whether or not a reference condition (for example, home or other) is satisfied, based on the type of a registration point registered by the user. It is suitable mainly when applied around the home.
[0013]
Alternatively, the detected current location may be accumulated, and an area where the vehicle travels frequently based on the accumulated current location (trajectory data) may be set as the guidance prohibited area. Further, the registered point satisfies a first reference condition (for example, whether the house is home or not) and the trajectory data of a predetermined range (predetermined range) including the registered point is stored in a second reference condition (for example, a predetermined number of times). A predetermined range may be set as the guidance-prohibited area on the condition that the above-mentioned traveling is satisfied.
[0014]
FIG. 3 is a diagram showing an example in which the guidance prohibited area is set by the address information.
For example, a guidance-prohibited area is set for each administrative division, such as a prefecture unit shown in the shaded area shown in the figure, or a municipal unit shown in the black area shown in the figure, and the route is set in the same manner as in FIG. If the route is not set, the guidance is not automatically output regardless of when the route is not set.In this area, guidance is provided only when there is dynamic information or when there is a request from the user, and other guidance is provided. Not to do. The guidance prohibited area can be set manually, and one or a plurality of administrative division units or a part of the administrative division unit can be set as the guidance prohibited area.
[0015]
In the present embodiment, guidance on dynamic information performed in the guidance prohibited area as described above includes, for example, traffic information such as traffic congestion and regulation information from VICS (registered trademark), information related to driving advice, and vehicle information. It is a guide to inform etc. In addition, when the route set due to traffic congestion or regulation is switched, guidance is provided even in a prohibited section. The guidance information related to the driving advice includes, for example, guidance for judging the approach speed to a curve and prompting a decrease in speed, guidance for notifying that a breaker at a railroad crossing is going down, and the state of a traffic light (red / Blue). In addition, examples of guidance using vehicle information include refueling guidance and light-on guidance in bright places.
[0016]
The guidance provided by the user request is as follows: When the user presses a button, etc., and wants to know where the current location is, maintenance guidance that informs when oil change is required, and when the engine is turned on, "Good morning" And the like, a calendar guide for notifying a public holiday, a memory guide with sound for attaching a voice or the like to a memory location, and other guides set by the user.
[0017]
FIG. 4 is a diagram illustrating an example of a guidance processing flow according to the present embodiment.
The current position of the vehicle is determined based on information from various sensors, traveling locus, route information, and the like (step S1). Next, it is determined whether or not the current location is in the guidance prohibited area (step S2). If the result of the determination is that the vehicle is not in the guidance prohibited area, it is determined whether or not the current location is on a route (step S3), and route guidance is performed while the vehicle is traveling on the route (step S4). In such a case, guidance for traveling off the route is provided (step S5). The guidance on the route includes, for example, branch guidance, direction guidance, boarding guidance for notifying that the user will start guidance on the route, driving advice on curves, railroad crossings, merging, and congestion regulation guidance. The guidance at the time of traveling outside the route includes performing guidance by determining a guidance target ahead of the current location as a road, and includes traffic jam, regulation guidance, and the like. In step S2, if the area is the guidance prohibited area, it is determined whether there is dynamic information or a user request (step S6). If so, guidance of dynamic information or guidance based on the user request is performed (step S6). Step S7). Next, it is determined whether or not the power is turned off (step S8). If the power is on, the process returns to step S1 and the same guidance processing is performed.
[0018]
FIG. 5 is a diagram showing another example of the guidance processing flow.
In this example, specific guidance information is output to the notification means regardless of whether or not the current location is in the guidance-prohibited area, and when the current location is in the guidance-prohibited area, it differs depending on whether traveling on the route or traveling off the route. It informs the guidance information.
First, the current location is determined (step S11), and it is determined whether or not there is dynamic information or a user request (step S12). If so, guidance of the dynamic information or guidance based on the user request is performed (step S12). Step S13). Next, it is determined whether or not the current position is on a route on the route (step S14). If it is on the route, route guidance is performed (step S15). If it is not on the route, guidance for traveling outside the route is performed (step S15). Step S16). Next, it is determined whether or not the power is turned off (step S17). If the power is on, the process returns to step S11, and the same processing is performed.
[0019]
FIG. 6 is a view for explaining the route guidance processing in step S15 in FIG.
It is determined whether or not the current position is in the guidance prohibited area (step S21), and if it is not in the guidance prohibited area, branch guidance, area guidance, curve, railroad crossing, and merge guidance are performed (steps S22 to S24). Also, when the vehicle is in the guidance prohibition area in step S21, a curve, a railroad crossing, and a merging guidance are performed (step S24).
[0020]
FIG. 7 is a diagram showing another example of the route guidance in step S15.
It is determined whether or not the current location is in the guidance prohibited area (step S31). If the current location is not in the guidance prohibited area, branch guidance (initial guidance, immediately preceding guidance) is performed (step S32), and direction guidance is performed (step S33). Branch guidance (intermediate guidance, enlarged view display) is provided (step S34), and then a curve or a level crossing junction is provided (step S35). This example is different from the case of FIG. 6 in that the branch guidance is performed in both the guidance-prohibited area and the other area, and the content of the branch guidance and the guidance output timing are different. It goes without saying that only one of the content of the branch guidance and the guidance output timing may be different.
[0021]
FIG. 8 is a diagram showing an example of the guidance process at the time of traveling off the route in step S16 in FIG.
It is determined whether or not the current position is in the guidance prohibited area (step S41). If it is not in the guidance prohibited area, curve guidance, level crossing guidance, and merging guidance are performed (steps S42 to S44). Guidance is provided in different guidance modes such as guidance (display only), railroad crossing guidance (display only), and merging guidance (display only) (steps S45 to S47).
[0022]
In the above example, it is determined whether or not the vehicle is in the guidance prohibited area based on the current location, and guidance is performed based on the determination result. However, the determination may be performed based on the guidance target point. For example, it is determined whether or not a guidance target point such as an intersection, a railroad crossing, a road construction point, an interchange, or a congestion occurrence point is in a guidance prohibited area. If the guidance target point is in a guidance prohibited area, guidance is automatically output. Instead, guidance may be performed only when there is dynamic information or when there is a request from the user, and guidance may not be performed otherwise. In addition, instead of the guidance target point, the determination is made based on the guidance output point a predetermined distance before the guidance target point, and when the guidance output point is in the guidance prohibited area, the guidance is not automatically output, and the dynamic information is not output. The guidance may be performed only when there is a request, or when there is a request from the user, and may not be performed in other cases.
[0023]
When the navigation device has a current position detection unit, an input unit, a communication unit, and the like, and transmits the current position information and the destination information to the center, the center searches for a route, and the searched route information and guidance information are transmitted. The navigation device may be configured to transmit the information to the navigation device and output the received guidance information. In this case, if a desired guidance prohibited area is selected from the information on the guidance prohibited area set by the input means of the navigation device or the information on the guidance prohibited area presented from the center side and transmitted, the center side displays the current location information. And based on the current location, the guidance target point, or the guidance output point, determines whether those points are in the guidance prohibited area.If the current location, the guidance target point, or the guidance output point is in the guidance prohibited area, Does not output guidance automatically, but provides guidance only when there is dynamic information or when there is a request from the user, and does not provide guidance otherwise. In addition, it is desirable to be able to select any of the points related to the current location (current location, guidance target point, guidance output point) as a reference.
