DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traffic information notifying apparatus for receiving traffic information and notifying a passenger.

[0002]

2. Description of the Related Art In order to make a vehicle reach a destination as soon as possible, a system has been proposed which receives road traffic information from an information center and makes a travel plan based on traffic information obtained. . For example, in the system disclosed in Japanese Utility Model Laid-Open No. 61-128799, a driver communicates with an information center by telephone to obtain necessary traffic information.

In another traffic information system, traffic information is transmitted from a traffic information center by radio waves,
The vehicle receives this information while traveling. In such a situation, it is impossible for the driver to always pay attention to traffic information, and it is not necessary in normal driving conditions. But if you ignore it altogether,
Necessary information cannot be obtained.

[0004] In the conventional traffic information system, there is no means for distinguishing necessary information from information that is not necessary, so that traffic information cannot always be used effectively. The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a traffic information notification device that can evaluate only necessary traffic information and effectively use the information.

[0005]

To solve the above-mentioned problems, the present invention is configured as follows. The traffic information notification device according to the present invention, receiving means for receiving traffic information, a traveling route on which the vehicle is traveling, a storage time for storing traffic information of the traveling route of the traveling time and the traveling time, Information notifying means for notifying traffic information, and at the same time, when traveling on the same traveling route, the traffic information stored in the storage means and the received traffic information, the traveling time, traveling point, stored traffic information and received traffic information Detection means for detecting that there is a difference between the content stored in the storage means and the content received by the reception means that exceeds a predetermined range, and the detection means detects a difference between the storage information and the reception information. A warning notification means for notifying that a difference is detected between the information and, when the difference is detected, the received information is stored in a storage means together with a traveling time and a traveling point. Characterized by comprising a learning unit that.

[0006]

According to the present invention, the receiving means receives information from the traffic information center, and the received information is stored in the storage means. This information may be transmitted using a network such as a radio, or may be transmitted by a multiplex communication system. The information to be stored is information for specifying the traveling route on which the vehicle is traveling, the traveling time at that time, and the traffic condition of the route at that time, for example, the degree of congestion,
Whether it is under construction or not. In this case, the same traveling time is divided, for example, every hour per day, and the same time is set when the traveling time zone of the vehicle coincides.

[0007] In addition to the travel time, the travel month, day, and day of the week may be stored. In this way, for example, the traffic condition is often different between the weekend and the weekend, but in such a case, the difference can be stored respectively, and the traffic condition and the weekend different from the normal weekday can be stored. It is convenient for those who use the car regardless of weekends and weekends because it is possible to know each of the unusual conditions in. On the other hand, if you drive on the road only on weekdays, you may not need much weekend information. The information from this traffic center is preferably digitized information.

The detecting means determines whether or not the information currently received is the same as the information stored in the storage means. Then, when it is detected that there is a difference between the two, the notifying unit notifies the notification, and the notifying unit notifies the driver based on this. For example, the degree of traffic congestion is ranked as A, B, C, and the like. If the stored information is A and the information received this time is B in the same travel route and the same time zone, the detection means will Detect and notify the notification means. The notifying unit notifies that information B different from the stored content A has been input. In this case, voice notification and visual notification are general, and in the case of voice notification, the contents of the information are notified to the driver by voice. In the case of visual display, flushing or the like is performed in addition to normal display.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic configuration of a traffic information notification device according to the present example. The traffic information notification device 1 of this embodiment preferably includes a microcomputer and includes a control unit 2. The control unit 2 includes a receiving unit 4 that inputs information connected to an antenna 3 that receives wireless traffic information from a traffic information center, a control unit 5 that receives and processes information from the receiving unit, The control unit 5 includes a storage unit 6 that stores the processed information, a CRT that displays the processed information, and a switch 7 that is connected to the control unit 5 and switches the display content of the CRT 6. .

FIG. 2 shows the control contents of the notification device of the present embodiment. First, the control unit determines whether or not traffic information has been received (step S).
1). This traffic information is a fixed digital signal, for example, as shown in FIG. 3, after specifying a month, a day, a day of the week, a time, or a time zone, and then displaying a point (for example, a route display, an intersection display, etc.) and traffic information of the point (for example, For example, the degree of congestion, the presence or absence of construction, etc.) are transmitted one after another. Then, the control unit determines whether the received information is stored (step S2). In this case, it is determined whether information on the same date (day of the week) and in the same time zone is stored. If at least one of the received traffic information is stored, the determination is "YES". If the information is completely different, the determination is "NO".

If the information has already been stored, the stored information is compared with the information input this time (step S3). Then, it is determined whether the received information and the stored information all match (step S4). In this determination, when it is determined whether or not individual information matches, if the difference between the information and the stored content is within a certain range, it is determined that they match. For example, when traffic information indicating the length of a traffic jam in km is input, it is not necessary for the traffic lengths to completely match.
When it is confirmed that the vehicle enters the area within the predetermined range, it is determined that the congestion length is the same. If there is any information that does not match any of the stored information and the current input information, the information is divided into information that matches and information that does not match, and the information that matches is displayed normally. If they do not match, or if information that is not stored is included, a notification is issued to alert the occupant (step S5). In the case of this example, the screen flashes in addition to the normal display. In addition, a special notification may be issued by voice to alert the user in addition to the normal information. In the case of the voice notification, if the received traffic information is the same as the stored traffic information, the notification is not performed and the voice notification may be performed only when there is a difference. By doing so, it is possible to perform effective audio notification without reducing the occupant's concentration.

If "NO" in step S2, that is, if it is determined that the input information of the same day of the week, time, and place is not stored, the process proceeds to step S5 to notify the occupant of attention. . If they match, there is no need to evoke a driver, and in this case, normal traffic information is reported (step S6). Then, the traffic information input this time is newly stored, that is, learning of the traffic information is performed (step S7). In the above example, the traffic information is stored for each day of the week or for each month, but this is not always necessary. If information is stored for each day of the week or month and day, when traffic conditions differ depending on the day of the week, appropriate notification can be made and effective. On the other hand, if the traffic condition does not change much depending on the day of the week,
Alternatively, when driving is not performed on a day of the week or a month when traffic conditions change, it is not necessary to store information for each day of the week or month. In such a case, it is effective for some drivers to notify the change in the traffic condition according to the time zone.

In view of such circumstances, for example, storing traffic information for each day and time zone, storing information for each month and day, and storing information for each time zone regardless of the day of the week and month. The driver may be allowed to make a selection such as storage.

[0014]

According to the present invention, it is possible to notify a driver or an occupant of traffic information in a case where the traffic condition is different from a normal traffic condition accurately and promptly with a simple configuration, so that efficient driving is possible.
