Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for wirelessly guiding a moving body.

[0002]

2. Description of the Related Art As a device for supporting the operation of a moving body such as a vehicle, a route guiding device mounted on the moving body is known. The route guidance device collates the information indicating the position or behavior of the user, which is obtained by the positioning device, with the destination or the traveling route which is registered and set by the user in advance, and the map information stored in the storage medium such as a CDROM. To do. The route guidance device displays the information obtained as a result, for example, information about a corner in front of the moving body, an intersection, an interchange, etc. on the screen of a display device such as a small CRT, LCD, or outputs an alarm by voice. By using this device, the operator of the moving body can detect the existence of a corner or the like in advance, and can reliably and swiftly reach the destination even in unguided land.

What is necessary to realize the route guiding device is a means for detecting the position or behavior (speed, acceleration, etc.) of the mounted moving body, that is, a positioning device for positioning the moving body. . As a positioning device, for example, GPS (Global
Positioning System), GLONASS (Global Orb
GNSS such as oting Navigation Satellite System)
G using (Global Navigation Satellite System)
There is an NSS receiver. The GNSS receiver receives its orbit information from 3 to 4 positioning satellites out of a predetermined number of positioning satellites in orbit around the earth, while obtaining the distances to these positioning satellites The position of oneself is obtained based on the orbit information. Further, it calculates its own speed based on the Doppler information regarding the signal received from the positioning satellite. In addition, as a positioning device, a self-contained navigation device that detects the behavior (acceleration, speed, etc.) of oneself by using an acceleration sensor or the like and accumulates the behavior at an initial position to perform positioning has been widely used. It is used. These, GNSS
Since the receiver and the self-contained navigation system each have advantages and disadvantages, both are often combined. For example, there is a combined mode in which positioning is performed exclusively by the autonomous navigation when the signal from the positioning satellite cannot be received, or the accumulated error caused by the autonomous navigation is compensated by using GNSS. In recent years, these navigation devices have also been further combined with map matching technology to provide users with
Information is often provided by map images.

[0004]

However, the conventional route guiding device having such a structure has some problems. The first problem is that the behavior of other moving bodies cannot be known. That is, in order to safely and appropriately operate a mobile body, it is necessary to know how other mobile bodies behave in addition to receiving route guidance. Conventionally, for example, there has been a collision preventing radar that detects a vehicle traveling immediately before the host vehicle. However, if a vehicle that is heading for the same destination as the one you are on is already ahead of you (for example, if the guided vehicle is ahead of you), it will detect this preceding vehicle. I couldn't do it.

The second problem is that even if a moving body aiming at the same destination as the moving body on which the user is boarding is already in advance, the user himself / herself will find the destination or route. If there is no guidance regarding the above, there is a point that it is necessary to receive route guidance, and therefore the user has to register and set his own destination or route in advance. It is desired that this troublesome work such as registration and setting can be omitted. Further, if the information is provided by voice communication by wireless from the pilot of the preceding moving body, it is possible to quickly reach the destination without receiving the route guidance from the route guidance device, For that purpose, a voice communication radio must be mounted separately from the route guiding device on the side of the preceding moving body (guide) and on the side of the moving body (guided person) in which the user is present. In addition, it is usually difficult to accurately instruct the route only by verbal communication, and thus it is difficult to achieve accurate guidance in voice communication.

The present invention has been made to solve the above problems, and a behavior of another moving body is visually displayed or voiced by a guidance device.
The purpose is to enable safer and more accurate operation.
Another object of the present invention is to accurately inform the user of the position or behavior of the preceding moving body so that the user can reach the destination securely and quickly. The present invention further requires the user to pre-register and set his or her own destination or route when a moving body aiming at the same destination as the one on which the user is boarding is already in advance. The purpose is to realize a device with higher usability. An object of the present invention is to eliminate the need to mount a voice communication radio device separate from the guidance device, reduce the occupied space inside the moving body, and eliminate the ambiguity of guidance by voice communication.

[0007]

In order to achieve such an object, the guiding device according to the first configuration of the present invention provides means for detecting its own position and information about the position of another moving body. Means for wirelessly receiving, means for comparing the received information with one's own position, and means for visually displaying or audibly outputting information regarding the position or behavior of another moving body viewed from oneself based on the result of the comparison. It is characterized by being provided in a mobile body (including the case of being carried by an individual as well as being installed in a vehicle, and the like below).

The guiding device according to the second configuration of the present invention is a device for detecting its own position, a device for wirelessly receiving information on the position of another mobile unit, and another mobile unit based on the received information. It is characterized in that it is mounted on a moving body, and is provided with means for obtaining a traveling locus of the above, and means for visually displaying or audio-outputting information regarding the obtained traveling locus. This configuration further detects, when the self is traveling along the traveling locus of the other moving body, that the self has approached a corner or an intersection based on the obtained traveling locus and the detected position of the self. It is characterized in that the information notifying that is visually displayed or output as voice.

The present invention is further characterized in that it comprises means for automatically wirelessly transmitting its own position. The present invention is characterized by including means for wirelessly communicating with another mobile unit by voice.

[0010]

In the guiding device according to the first aspect of the present invention, first, the position of the self is detected while the information regarding the position of another moving body is wirelessly received. The received information is then compared to its location. The information obtained by this comparison, that is, the information regarding the position or behavior of the other moving body as viewed from itself is provided for visual display or audio output.
Therefore, in this configuration, since information regarding the position of another moving body is visually displayed or output by the guidance device,
Safer and more accurate operation is realized. Furthermore, when the other moving body is a moving body that precedes itself (for example, a guide vehicle), the user is accurately notified of the position or behavior of the preceding moving body, and as a result, the destination can be reliably and quickly delivered. It is possible to get there. Further, if the preceding moving body exists, the user does not need to register and set his own destination or route in advance, so that the usability is improved. In addition, since it is not necessary to mount a voice communication radio separate from the guidance device only for guidance, the space occupied inside the mobile body is reduced and the ambiguity of guidance due to voice communication is eliminated. .

In the guiding device according to the second aspect of the present invention, first, the position of the self is detected, while the information regarding the position of the other moving body is wirelessly received. Next, the traveling locus of the other moving body is obtained based on the received information, and the information regarding the obtained traveling locus is visually displayed or output as voice. Therefore, in this configuration, since information regarding the traveling locus of another moving body is visually displayed or voiced by the guidance device, safer and more accurate operation is realized. In addition, as a result of being informed to the user of the traveling trajectory of the preceding moving body accurately, it becomes possible to reach the destination surely and quickly. In particular, when the self is traveling along the traveling locus of the other moving body, it is detected that the self is approaching a corner or an intersection based on the obtained traveling locus and the detected position of the self, and If the information to be notified is visually displayed or output by voice, the information necessary for operation can be obtained at an appropriate timing. Further, if the preceding moving body exists, the user does not need to register and set his / her destination or route in advance, so that the device has higher usability. In addition, since it is not necessary to mount a voice communication radio separate from the guidance device only for guidance, the space occupied inside the mobile body is reduced and the ambiguity of guidance due to voice communication is eliminated. .

Further, according to the present invention, the self position is automatically transmitted by radio. Therefore, it becomes possible for the self to guide another moving body. Further, since the transmission is automatic, there is no need for user operation for guidance. Further, when a means for wirelessly communicating with another mobile body by voice is provided, voice communication between the mobile bodies becomes possible as in the conventional case. Also in that case, it is not necessary to mount a separate voice communication radio.
