[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle traffic congestion forecasting system, and more particularly to a vehicle congestion forecasting system capable of displaying traffic congestion forecast information on a navigation device mounted on the vehicle.

[0002]

2. Description of the Related Art A conventional traffic information system is, for example, shown in FIG.
It is configured as shown in FIG. In FIG. 1, reference numeral 1 denotes a vehicle sensor installed on a specific road to detect the amount of vehicle passing, 2 denotes a communication line for transmitting information detected by the vehicle sensor 1, and 3 denotes a traffic information center equipped with a host computer. Reference numeral 4 denotes an FM broadcasting station or telephone station, reference numeral 5 denotes an FM multiplex wave or wireless telephone line, and reference numeral 6 denotes a vehicle for receiving information.

In this system, the latest information detected by the vehicle sensor 1 is always transmitted to the traffic information center 3 via the communication line 2 and the information is processed by the host computer of the traffic information center 3 so that the FM broadcast can be performed. Office or telephone office 4 to F
Vehicle 6 traveling using M multiplex wave or wireless telephone line 5
Provided to The information is transmitted by an FM wave from an FM broadcasting station like VICS or by a wireless telephone line like ATIS. Vehicle 6 that has received this information
Can know the traffic situation such as traffic congestion at each point in real time, and can appropriately drive the own vehicle 6 based on this information.

[0004]

By the way, according to this system, traffic information, for example, traffic congestion information can be known in real time, so that it is possible to take appropriate measures according to the traffic congestion situation at present. Have
Since the information is not traffic congestion information in the future, there is a problem that even if an automatic route search is performed by the navigation device, an appropriate route cannot be set in consideration of temporal traffic congestion information.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a vehicle traffic congestion forecasting system capable of predicting traffic congestion by collecting and processing driving information provided from a plurality of vehicles equipped with a navigation device. .

[0006]

SUMMARY OF THE INVENTION Accordingly, in order to achieve the above-mentioned object, the present invention comprises a plurality of vehicles equipped with a navigation device and a base station having a host computer, wherein the plurality of vehicles run. The base station transmits congestion forecast information by compiling the driving information transmitted from a plurality of vehicles, and provides the congestion forecast information in response to an information request from each vehicle. The second invention of the present invention is characterized in that traffic congestion forecast information provided from the base station can be displayed on a navigation device via a modem, and the third invention is further characterized in that: The invention is characterized in that traffic congestion forecast information provided from the base station can be displayed on a navigation device via a personal computer.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a traffic congestion forecast system according to the present invention will be described with reference to FIG.
The same parts as those of the conventional example shown in FIG. 6 are denoted by the same reference numerals, and detailed description thereof will be omitted. In the figure, the feature of the present invention is that, in addition to the information from the traffic information center 3, the base station 4 </ b> A also has travel information from a plurality of vehicles 6 (travel road name, travel lane, travel time zone, day of the week, (Season, etc.) is transmitted via a wireless telephone line or a dedicated wireless line 5A, and the traffic congestion forecast information is prepared by performing a tallying process by a host computer of the base station 4A, and the congestion forecast information is provided in response to a request from the vehicle 6. That is to say.

As shown in FIG. 2, the vehicle 6 includes a modem 8 and a portable telephone or radio 9 as a means for communicating with the base station 4A, in addition to the navigation device 7. The information received by the mobile phone or the wireless device 9 is displayed on the navigation device 7 via the modem 8,
The traveling information in the navigation device 7 is transmitted from the mobile phone or the wireless device 9 to the base station 4A via the modem 8.

[0009] In particular, the traffic congestion forecast information received by the mobile phone or the wireless device 9 includes time-based traffic congestion information when, for example, an automatic route search is performed by a navigation device.
Appropriate route setting can be made.

As shown in FIG. 3, a personal computer 10 is connected to the navigation device 7 of the vehicle 6 in place of the modem 8 and the portable telephone or the wireless device 9. The personal computer 10 incorporates traffic congestion forecast information from the base station 4A stored in a storage medium, and this data can be used for, for example, an automatic route search.

Next, a method of transmitting information from the vehicle 6 to the base station 4A will be described with reference to FIG. First, the vehicle side collects traveling information data such as the traveling state of the vehicle 6, the traveling road name, the traveling lane, the traveling time zone, the day of the week, and the season (step S1). The collected data is output from the navigation device 7 to the outside via the wireless telephone line or the dedicated wireless line 5A (step S2). Next, on the base station side,
The output collected data from the vehicle 6 is received (step S3). This collected data is stored on the host computer.
The newly received data is added to the past data, and all data are totaled (step S4). Then, this total data is stored in the memory (step S5), and the transmission and processing are terminated.

On the other hand, provision of information (total data) in response to an information request from the vehicle 6 is performed as shown in FIG. First, on the vehicle side, when the navigation device 7 requests traffic congestion forecast information (step ST1), a request signal is transmitted to the base station 4A via the wireless telephone line or the dedicated wireless line 5A. Next, the base station 4A receives a request signal from the vehicle 6 (step ST2). The data in the memory is searched based on this request signal, and the forecast data accompanying the request is read (step ST3). The read forecast data is transmitted from the base station 4A to the requesting vehicle 6 via the wireless telephone line or the dedicated wireless line 5A (step ST4). next,
On the vehicle side, the forecast data from the base station 4A is received and used by the navigation device 7 (step ST5).

According to this embodiment, by using such traffic congestion forecast information, when performing an automatic route search, it is possible to know a traffic congestion forecast for a road expected to pass in a few hours, and to obtain a higher quality route. Search becomes possible.

In addition, VICS, ATI
Even in an area where a traffic jam information service such as S is not provided, a traffic jam forecast can be created based on forecast data from the base station 4A.

It should be noted that the present invention is not limited to the above-described embodiment. For example, the base station can incorporate the functions of a traffic information center or the like and integrate them.

[0016]

As described above, according to the present invention, the traveling road name, traveling lane, traveling time zone, day of the week,
Information such as the season is transmitted to the base station via a wireless telephone line or a dedicated wireless line, and the base station creates traffic jam forecast information based on this information, and provides the traffic jam forecast information in response to a request from the vehicle. For this reason, when performing an automatic route search, for example, it is possible to know a traffic congestion forecast of a road that is expected to pass several hours later, and a higher-quality route search can be performed.

In addition, VICS, ATI
Even in an area where a traffic jam information service such as S is not provided, a traffic jam forecast can be created based on forecast data from a base station.
