Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation device mounted on a vehicle for detecting the position of the vehicle.

[0002]

2. Description of the Related Art For example, in a vehicle-mounted navigation device, a device for receiving an electric wave signal from an artificial satellite to detect an absolute position, or a reference point is set to integrate a traveling direction and a moving distance of a vehicle thereafter. A vehicle position detecting means such as one for detecting the relative position is provided, and the detected vehicle position is arranged on a map or the like from the storage means and displayed on the display device (special feature). Kaisho 58-
129212, etc.).

However, in the above-mentioned device, the display device for displaying a map or the like is generally placed outside the driver's visual field, and in order to see this display, the driver must consciously turn his eyes. I have to. Therefore, the driver cannot easily confirm the display, and there is a problem that the safety may be impaired.

[0004]

This application was made in view of the above-mentioned problems, and the problem to be solved is that in the conventional device, the display device is placed outside the driver's visual field. Therefore, the driver cannot easily confirm the display, which may impair safety.

[0005]

Therefore, in the present invention, information is announced by voice (acoustic) as needed. According to this, the driver can individually display the display device. It is possible to eliminate the need to see and to perform better navigation.

BEST MODE FOR CARRYING OUT THE INVENTION That is, the present invention has a detecting means for detecting its own position and a storing means for accommodating map data, and information relating to its own position detected by the detecting means at a predetermined time. In a navigation device that notifies the user by sound and also on the screen, the notification by sound switches between sound and other sound according to the content of the notification.

The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an example of a navigation apparatus to which the present invention is applied.

In FIG. 1, a sensor 1 for detecting the traveling direction of the vehicle and a sensor 2 for detecting the moving distance are provided. Then, the detection data from these sensors 1 and 2 is supplied to the CPU 3 which performs calculation and control, and this CPU 3
The current location of the vehicle is calculated at.

A display mode setting input means 4 is provided, and a signal from the setting input means 4 is supplied to the CPU 3. Further, a storage means 5 such as a CD-ROM device in which data of a road map is accommodated so that the vehicle can travel is provided, and the data from the storage means 5 is supplied to the CPU 3.

In the CPU 3, the above calculated current position data is arranged on the map data from the storage means 5, and a display signal arbitrarily provided with a mark or the like at the position of the calculated data. It is supplied to the display device 7 through the display control device 6. The display data of the map from the storage means 5 is directly supplied to the display control device 6.

As a result, the display device 7 displays the current position of the vehicle on the predetermined road map and displays the calculated data when the calculated data deviates from the travelable range of the map data. Processing such as rearrangement within the possible range is performed.

Further, in this apparatus, a storage means 8 is provided in which attribute information such as place name information is stored as voice data in association with the map data stored in the storage means 5 described above. Then, the voice data from the storage means 8 is stored in the CPU.
3 is called by 3 and is controlled by the CPU 3 through the voice reproducing device 9 and the voicing means 1 of the amplifier and speaker
0 is supplied.

Therefore, in this apparatus, for example, when the driver operates a notification button (not shown) provided in the setting input means 4, the CPU 3 causes the memory 3 to store the data of the current location based on the detection data from the sensors 1 and 2. 5, the attribute information (voice data) of the placed map data is called from the storage means 8, and the voice data is supplied to the voice means 10 through the voice reproducing device 9, thereby, It is possible to notify the name of the current location from the voicing means 10.

Further, in this device, the execution of the notification by voice is not limited to the operation by the driver described above. It is also possible to do so, and these can be used together.

Further, similar display may be performed on the display device 7 at the same time as the above-mentioned notification. As a result, it is possible to properly deal with whether or not the voice notification is heard.
Further, when this display is also used, the notification other than the driver's request may be displayed only, and instead, a beep sound or the like may be generated to call attention.

In this way, according to the above-mentioned device, the information such as the current location is announced by voice if necessary, so that the driver does not need to look at the display device one by one, and a better navigation is performed. be able to.

In the above-mentioned device, the notification by voice is not limited to the place name along the line, but may be the name of the next major intersection. In that case, the distance from the map data etc. to the intersection is calculated and at the same time You may make an announcement.

Further, peculiar points on the map (main intersections, in front of famous facilities, etc.) may be discriminated, and when these points coincide with the data from the position detecting means, the notification may be executed. In this case, a so-called accident-prone spot may be added to a part of the peculiar spots and a warning may be issued when the spot approaches.

Further, in the above-mentioned apparatus, the storage means 5,
If a large capacity device such as a CD-ROM device is used, 8 can be provided integrally. Further, the current position of the vehicle may be detected by receiving a radio wave signal from an artificial satellite and detecting the received data based on the received data.

That is, according to the above-mentioned navigation device, it has a detecting means for detecting its own position and a storing means for storing the map data, and the information relating to its own position detected by the detecting means at a predetermined time. In the navigation device that notifies the user of the sound by the sound and also on the screen, the sound makes it possible to eliminate the need for the driver to look at the display device one by one by switching between the sound and the other sound according to the content of the notification. It is possible to perform better navigation.

[0021]

According to the present invention, information is voice (sound).
As a result of the notification, it is possible to eliminate the need for the driver to look at the display device one by one, and to perform better navigation.
