Abstract

PURPOSE:To more satisfactorily execute the navigation by storing in advance the attribution information which contains place name information along a road on a map, as voice information and uttering a voice data at a prescribed time. CONSTITUTION:Sensors 1, 2 for detecting a position of a vehicle are provided, and also, data of a map by which the vehicle can run is contained in advance in a storage means 5 so that it can be displayed on a display device 7. Also, to this map data, attribute information containing place name information along a road is added as voice information and stored in advance in an attribute information storage means 8. In this state, at a prescribed time, the voice information is read out of this attribute information storage means 8, and voice data is reproduced and uttered from an uttering means 10 through a voice reproducing device 9.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an on-vehicle navigator device that is mounted on a vehicle and detects the position of the vehicle.

[Summary of the invention]

The present invention relates to an in-vehicle navigator device, and by providing voice data with place names along roads on a map, it is possible to announce information such as the current location by voice as needed, thereby improving navigation. It is something.

[Conventional technology]

So-called in-vehicle navigation devices detect absolute positions by receiving radio signals from artificial satellites, or detect relative positions by setting a reference point and integrating the vehicle's heading, distance traveled, etc. A vehicle position detection means such as one that detects the vehicle position is provided, and the vehicle position detected by this means is recorded in 1. It is arranged on a map etc. from the α means and displayed on a display device (Japanese Patent Laid-Open Publication No. 129212/1983, etc.).

[Problem that the invention seeks to solve]

However, in the devices described above, the display is generally placed outside the driver's field of vision, and the driver must consciously look in that direction in order to see the display. Therefore, there are problems in that the driver cannot easily check the display, and safety may be compromised.

This application has been made in view of these points.

Means for Solving Problem C] The present invention provides a means (CPU (3)) for detecting the position of a vehicle in which it is mounted based on information (sensors (1) (2)).
and a storage means (5) storing data of a map on which the vehicle can drive, and attribute information including place name information along the road on the map is added (stored) to the storage means as audio data. means (8)) detects the attribute information in the vicinity of the vehicle position detected by the detection means at a predetermined time and reproduces the audio data (device (9)) and utters (means (10)
) is an in-vehicle navigator device.

[Effect]

According to this, information such as the current location is announced by voice as necessary, thereby eliminating the need for the driver to look at the display device every time, and enabling better navigation.

〔Example〕

FIG. 1 shows the configuration of the main parts. In this figure, (1) is a sensor that detects the traveling direction of the vehicle, and (2) is a sensor that detects the distance traveled, and the detected data from these sensors (1) (2) is used for calculation and control by the CPU (3). The current location of the vehicle, etc., is calculated.

Further, (4) is a setting input means for display mode, etc., and a signal from this setting input means (4) is supplied to the CPU (3).

Furthermore, (5) is a storage means such as a CD-ROM device which stores road map data on which the vehicle can travel, and data from this storage means (5) is supplied to the CPU (3).

In this CPU (3), the storage means (5
) The calculated current location data is arranged on the map data from ), and a display signal with an arbitrary mark or the like provided at the position of this calculated data is supplied to the display device (7) through the display control device (6). be done. This allows the display device (7)
The current location of the vehicle is displayed on a predetermined road map, and when the above-mentioned calculated data deviates from the drivable range of the map data, the calculated data is relocated within the drivable range. Processing takes place. Note 1: The map display data from α means (5) is sent to the display control device (6).
supplied directly to

Further, (8) is a storage means in which attribute information such as place name information is stored as voice data in relation to the map data stored in the storage means (5), and this storage means (8)
) is called up by the CPU (3) and transmitted through the audio reproduction device (9) controlled by the CPU (3) to the amplifier and speaker sounding means (10).
).

In this device, for example, when the driver operates a notification button (not shown) provided on the manual setting means (4), the CPU (3) performs a process based on the detection data from the sensors (1) and (2). Means for storing current location data (5)
on the map data, and calls the attribute information (audio data) of the placed map data from the storage means (8),
By supplying this voice data to the voice generating means (10) through the voice reproduction device (9), the voice generating means (10) can announce, for example, the name of the current location of the vehicle.

In this way, according to the above-mentioned device, information such as the current location is announced by voice as necessary, thereby eliminating the need for the driver to look at the display device every time, and enabling better navigation. .

In addition, in the above-mentioned device, the audio announcement is not limited to the name of a place along the line, but may also be the name of the next major intersection, etc. In that case, the distance to the intersection can be calculated from map data etc. and announced at the same time. You may also do so.

Furthermore, in the above-mentioned device, the execution of the audio notification is not limited to the driver's operation, but can also be performed automatically, for example, at a predetermined distance traveled by the vehicle, or at a predetermined time interval, or by detecting a change in the vehicle's course. They can also be used together.

Furthermore, specific points on the map (major intersections, in front of famous facilities, etc.) may be determined, and an announcement may be made when these points match the data from the position detection means. In this case, it is also possible to add a so-called accident-prone point as part of the singular points and issue a warning when the point approaches.

Further, a similar display may be made on the display device (7) at the same time as the above-mentioned notification. With this, it is possible to effectively deal with the sound of the voice announcement. Further, when this display is used in parallel, the only notification other than the driver's request may be displayed, and instead a beep sound or the like may be generated to draw attention.

Further, in the above-mentioned device, the storage means (5) (8) are C
When using a large-capacity device such as a D-ROM device, these devices can be integrated.

Furthermore, the above-mentioned current location of the vehicle can also be detected by receiving a radio wave signal from an artificial satellite and based on the received data.

〔Effect of the invention〕

According to this invention, information such as the current location is announced by voice as necessary, thereby eliminating the need for the driver to look at the display device every time, and enabling better navigation. became.
