The present invention is characterized in that it searches for a road map of the intersection to which the bulletin board is attached, and displays the map.

[Effect]

When a signal is received or the driver inputs information, a road map of each intersection is displayed, and the route is displayed with arrows, etc. as shown in the embodiment below.

〔Example〕

Means for storing road data, central processing unit, display device,
In a driving support device equipped with an input device, means for storing a road map of intersections on a route between a predetermined destination and a starting point, codes, signals, names, signs, symbols, numbers, etc. attached to each intersection. The present invention includes means for inputting information, means for searching for a road map of the intersection based on the input information, means for displaying the map, and the like. As one of the The present invention includes means for searching a road map of an intersection and means for displaying the map. As one example, different names, signs, symbols, numbers, etc. are posted at each intersection, and there is a method for inputting these names, signs, symbols, numbers, etc. using keys, touch screens, voice, etc., and a system based on the input information. The present invention also includes means for searching for a road map of the intersection to which the bulletin board is attached, and means for displaying the map.

In a driving support method that stores road data, centrally processes it, inputs information, and displays it, a road map of intersections on the route between a predetermined destination and starting point is stored, and a code is attached to each intersection. , when a signal, name, sign, symbol, number, etc. are input, a road map of the intersection in question is searched based on this input information and a chain link is displayed. As one example, a transmitter that emits a different signal is installed at each intersection, the signal is received, the signal is read, and based on the read information, the information of the intersection where the transmitter is installed is determined. Search road maps and display chain marks.

As an example, different names, signs, symbols, numbers, etc. are posted at each intersection, and when these names, signs, symbols, numbers, etc. are input using keys, touch screen, voice, etc., the information is displayed based on the input information. Search the road map of the intersection where the bulletin board is attached, and display the chain mark.

Set a course between the destination and the starting point, add background information, phone numbers, and other related information to the road map of the intersections along this course, and fill in symbols and signs such as arrows to indicate the course. For example, when showing outbound and return routes on a single diagram, the distinction is clearly indicated using letters, symbols, colors, etc.

In principle, the road map displayed will be at intersections where you will turn left or right according to the course, and will also target intersections where it is easy to get lost.

The signal emitted by the transmitter may be a radio wave, a laser, or any other signal that can emit a different signal.

It is preferable for the transmitter to emit a signal all the time, but it is also possible for the receiving side to emit a signal that commands the transmitter to operate, and for the transmitter to operate only when the signal is received.This is a command issued by the receiving side. The signal depends on the driver's operation, but if the transmitter is equipped with a vehicle detection function, the transmitter will only operate when necessary, so it is desirable when considering the impact on the radio wave environment. It is desirable to install a landmark that indicates the location of the transmitter.

In embodiments where the driver's number, name, etc. are displayed, it is desirable to use fluorescent paint, neon lights, lighting, and color schemes to make the vehicle easily recognizable day and night.

It is desirable that the signal emitting part of the transmitter be housed in a cover that is open only in a certain direction, and that the open part gives directionality to the signal toward the course.

You can display different road maps (upside down) by giving different signals to the outbound and return trips, or display the same map by giving the same signal to the outbound and return trips (the routes for the outbound and return trips are displayed upside down). (along with pointing arrows, etc.), the signal is given directionality and sent only to the course, and a notification signal is sent to roads other than the course to make the driver aware that the intersection in question is on the course. It is desirable that the driver be notified by sound or display when this signal is received.

When displaying numbers, names, etc., it is desirable to point the display toward the course so that it is easy to see which roads among the roads that intersect at intersections constitute the course.

At this time as well, in order to make the driver aware that the intersection in question is on the course, it is desirable to set a landmark that can be seen from roads outside the course and that can call the driver's attention.

When arrows indicating outbound and return routes are shown on the same map, it is desirable that the driver input keys or other input to rotate the road map so that the current location is at the bottom and the route is at the top. .

When implementing the present invention, a distance sensor and a direction sensor are not required, and the device can be separated from the automobile, so it can be implemented as a so-called electronic notebook.

When implementing the device according to claim 2, it is preferable to combine the receiver and the electronic notebook into one unit, but it is also possible to separate only the antenna section, position it at a location advantageous for reception, and connect it with a cord. Or, it is preferable to use a cordless type.

The electronic notebook can be any conventional general type as long as it has a display section, storage section, central processing section, and input section.It is preferable to use voice input for input, but it can be used with kana keys, numeric keys, symbol keys, evening keys, etc. It may be selected depending on the input mode such as Sochi screen or writing, and the type of information.

Regarding the display, it is desirable that the currently displayed road map continue to be displayed until a different signal is received or the driver inputs different information.

It is desirable to display the distance to the next intersection or a point where it is easy to get lost and the diagram will be displayed.

FIG. 2 shows an example of the processing procedure. Once the signal is received (step 1), the road map is retrieved (step 2).
, is displayed (step 3), and it is determined whether there is a signal. If it is determined that there is no signal (no in step 4), return to step 3, and if it is determined that there is a signal (yes in step 4).
s) Determine whether the previous signal and the current signal are the same (or not), and if it is determined that they are the same (yes in step 5), step 3
If it is determined that they are not the same, the process returns to step 2 (no in step 5).

FIG. 3 also shows an example of the processing procedure. When information is input by the driver (Step 1), the road map is searched (Step 2) and displayed (Step 3), and it is determined whether there is any input or not (No in Step 4). ) Return to step 3, and if it is determined that there is (yes in step 4), return to step 2.

〔Effect of the invention〕

According to the present invention, a road map of intersections and points where it is easy to get lost is searched and displayed by the driver or by automatically inputting information, and symbols such as arrows indicating the route are shown in the closed country, so that the driver can be assured. can be guided to
