(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of a traffic information voice guide device according to the present invention. In describing the traffic information voice guide device, parts that are the same as or correspond to those in the conventional configuration will be described using the same reference numerals as in FIG.

In FIG. 1, a positioning device 11 includes, for example, a distance sensor and a direction sensor. The current position (traveling) position of the own vehicle is determined by detecting the traveling distance from the starting point by the distance sensor and the traveling direction by the direction sensor. Is detected. CD-ROM (map database) 12 stores map information in advance,
This map information is displayed on the display 13 via the processing device 16. The teleterminal receiver 14 receives a plurality of traffic information data (numerical data) representing the traffic information transmitted from the teleterminal radio base station through the antenna 15, and receives the plurality of received traffic information data via the processing device 16. Display 13
It is displayed above. And voice synthesis means
At 17, the plurality of traffic information data (numerical data) are converted into voice and output, and guided to the driver.

In this embodiment, since the traffic information is output by voice, the display 13 is not necessarily provided.

FIG. 2 is a flowchart showing a processing method of the processing device 16. In step S1, an attribute is searched based on the link number.

Here, a table required for the search is created in advance for each link number.

FIG. 3 is a diagram showing an example of the search table described above. In the search table shown in FIG. 3, each link number (section data) and data representing the attribute of each link number (section attribute data) are held in association with each other.

In this section attribute data, as shown in FIG.
Road (highway, road) corresponding to link number (section data)
Name data, data indicating directions (up / down, outer / inner), data representing an intersection serving as a starting point of a corresponding section, data representing an end point of a corresponding section, data representing a length of a corresponding section, and Corresponding roads (roads,
For example, as section attribute data of the link number (section data) 005, the name data is [200] representing Hibiya-dori, and the data representing the direction is Shiba 5-chome direction. , The starting intersection data is "011" representing Otemachi, the ending intersection data is "012" representing Hibiya, and the data representing the section length is
“001” representing the predetermined length and section order data are represented as “001” representing the first in the arrangement order on the same road (street).

Therefore, by searching the table, the road name data, the section length data, and the road (street) corresponding to the plurality of link numbers (section data) included in the plurality of pieces of reception data received by the teleterminal receiver 14 are obtained. Section attribute data such as section rank is obtained.

Then, in step S2, the section attribute data corresponding to each link number (section data) obtained by the search and the traffic congestion state, the regulation content, etc. corresponding to each link number (section data) included in the received data. Is referred to as “name data” (“street name”, for example, Hibiya street in FIG. 3) in the searched section attribute data.
By using as a key, one voice guide text data corresponding to a plurality of traffic information data is created. Further, in step S3, the voice synthesizing device 17 converts the generated voice guide text data into voice and outputs it.

FIG. 4 shows a specific processing example. Data content is 9th
This is the same as the conventional example shown in FIG. FIG. 9A shows a plurality of pieces of received data 501 and 502, and the congestion information of link numbers 2 and 5 indicating continuous sections on the road B is the content thereof. Information type
001 represents traffic congestion information, and 01002 in specific traffic situation data representing traffic congestion conditions, regulation contents, and the like, represents, for example, "natural traffic congestion, and a speed of 20 km or less."

Referring to FIG. 9, in the table, as the section attribute data of link number 2, "name data → B road", "start intersection data → C intersection", "end intersection → b intersection" and the like are respectively linked numbers. 2, and as the section attribute data of the link number 5, “name data → B road”, “start intersection data → ho intersection”, “end intersection → ha intersection” and the like are respectively linked. It is held in association with the number 5.

Accordingly, the processing in steps S1 and S2 causes the fourth
As shown in FIG. 4B, received data 501 and 502 corresponding to a plurality of continuous sections shown in FIG. 4A are represented by “1” in the section attribute data (B road in FIG. 4). The text data for voice guidance is compiled as two voice guide text data, "Natural congestion of 20 km / h or less and 3 km / h from the intersection of Route B to the intersection of B and E". Then, 1 corresponding to the plurality of generated reception data is set.
One text data is converted into voice and output. Here, the length of the congestion is guided by adding to the length of each link defined as the section length data in the table (third section).
(See section length data in the figure.)

As described above, in the present embodiment, the processing device 16 edits a plurality of link number data (section data) of each of a plurality of reception data and traffic condition data corresponding to a plurality of sections using a commonly known road name (name data) as a keyword. In this way, a plurality of traffic information data (numerical data) are written into one text data, and then the voice is guided to the driver by the voice synthesizing means 17, so that even if the driver concentrates on driving, much traffic information can be obtained. Can be obtained, and a marginal operation can be guaranteed.

In particular, the traffic information data has a predetermined data format (“information type”, “link number (section data)”, “traffic situation data”) as shown in FIG. Since the traffic information data has a data structure as described above, when the traffic information data is simply converted into a voice, a voice indicating a traffic condition of each section is individually output.

However, even if the traffic condition of each section is simply output as a voice in this way, the driver cannot immediately recognize the section of the road on which road the traffic condition is output as the voice. You will see the traffic information displayed on the container, and you cannot say that the voice guide is being used effectively.

Further, as shown in FIG. 9, since the sections of each road are finely divided for each intersection, for example, when the same type of traffic situation (for example, traffic congestion) continues in a continuous section on the same road, As described above, when simply outputting the traffic situation for each section by voice, the driver repeatedly listens to the same traffic situation, which is troublesome and may hinder the driver's driving concentration.

On the other hand, in the present embodiment, when a plurality of pieces of traffic information data representing the traffic conditions of different sections on the same road are received, the traffic situation data of the different sections is stored in the table shown in FIG. By editing the name data representing the road name obtained by the search as a key, it is possible to output the voice in association with the common road name instead of vaguely outputting the voice in units of sections. By listening to the voice output guide, it is possible to immediately recognize on which road section the traffic condition is being guided. Therefore, the driver can grasp the traffic condition of each road without looking at the display only by listening to the voice guide, and it is possible to guarantee the driver sufficient driving.

Further, in this embodiment, even when the same type of traffic condition (for example, traffic congestion) continues in a continuous section on the same road, the continuous section data and the corresponding section attribute data are replaced with the same road name data. Is compiled as one section data using as a key, and the combined one section data and the same type of traffic condition data are edited, so that the continuous section can be output as a voice by taking the continuous section as one unit. . Therefore, even if the same type of traffic condition in a continuous section of the same road continues repeatedly, the driver does not repeatedly hear the same type of traffic condition, which contributes to further improving the driver's concentration on driving. Can be.

It should be noted that the present invention is not limited to the above embodiment, and various modifications are possible. For example, in the above embodiment, if the same content as the voice output is displayed on the LCD 13a on the display 13 as shown in FIG. 5 and guided in parallel, the traffic information output by voice can be visually displayed on the LCD 13a. Can be confirmed. And congestion or regulation, area designation, street name (road name data)
Information such as designation (general road or Metropolitan Expressway) may be selected and edited, and voice guidance may be provided.

Alternatively, the detour may be sound-guided together with information on traffic or regulation (traffic situation data). That is, the ninth
In the example of the figure, if it is desired to drive from the upper left of the D road to the upper right of the B road, the link 2 is congested. please. ] And voice guidance.

Further, since the voice has a shortcoming of being transient, it may be possible to output continuously or repeatedly at a predetermined time interval. In addition, each time new data is received, the voice is automatically edited and guided. You may do so.

〔The invention's effect〕

As described above, according to the present invention, the "street name"
By editing traffic information with (road name data) or editing numerical data related to traffic information and outputting it as voice, the driver can obtain traffic information audibly and audibly, which is safe for the driver. In addition, it is possible to provide an easy-to-understand drive guide, and it is possible to ensure a sufficient driving.

According to the present invention, a plurality of pieces of traffic information data representing traffic conditions in different sections on the same road can be output as voices in association with section attribute data such as the same road name. By listening to the voice output guide, it is possible to immediately recognize which road section on which road the vehicle is guiding, without looking at the display, thereby further improving the driver's driving margin. .

Further, according to the present invention, when traffic conditions of the same type (for example, traffic congestion) continue in a continuous section on the same road, the traffic condition of the continuous section is output as a sound by using the continuous section as one unit. Therefore, it is not necessary to repeatedly output the same type of traffic situation as a voice, and it is possible to further contribute to improving the driver's concentration on driving.
