Description

  The present invention relates to a road traffic information distribution system and an in-vehicle terminal device that mutually provide and use road information and the like recognized by drivers nationwide.

  On highways, information such as accidents, traffic jams, weather speeds, chain restrictions, and closed roads are informed on an electronic bulletin board or can be confirmed on AM radio 1620KHz, but not on ordinary roads. It's a new memory that last year's heavy snowfall (a sudden change in weather) caused the car to stagnate for many kilometers and stay overnight. In the previous Great East Japan Earthquake, there were many people who missed the tsunami due to traffic congestion. This is also the case in the case of landslides, bridge damage, tunnel fires, etc. The earlier this information is transmitted, the better, but the information from the Internet from public organizations such as TV and radio news and the Japan Meteorological Agency does not necessarily correspond in real time to individual specific circumstances such as regions and roads.

  There is also a road traffic information provision service system called VICS (registered trademark: Vehicle Information and Communication System), but it is difficult to say that it has spread to all navigation users. Is the main service target, and it cannot be said that it is adequate for rural areas, mountainous areas and remote areas. In addition, since it becomes information after the traffic jam occurs, there is a case where the traffic jam is already resolved when the point is reached. On the other hand, there is a case where the intention is to select a vacant route, but when it reaches that point, traffic congestion has started. In addition, there are cases where there is no actual traffic jam because it is judged that there is traffic jam, such as street parking, parking waiting queues, road construction vehicles, etc. Yes, and the roadside tree near the sensor (which varies considerably depending on the season) may be judged as a traffic jam, so it is necessary to pay sufficient attention to the information. ”(Wikipedia“ Road Traffic Information Communication System ” reference).

  Moreover, a road traffic information distribution system called smart loop traffic jam information (registered trademark) is known (see http://pioneer.jp/carrozzeria/rakunavi-lite/navigation/traffic.html#section02). This information is said to be able to run the route that arrives faster with accurate grasp of arrival time by using travel history data provided by users nationwide in addition to VICS traffic congestion information , The data provided is merely the driving history of the car, that is, the data of how long it took from where to where, and it is not realistic as the user's identification information, sudden accidents and disasters It is not always possible to respond to emergencies.

  By the way, a social networking service (SNS) that builds a connection (social network) between people on the Internet is known. The main purpose of social networking services is communication between people, means and places to promote communication between friends and acquaintances, hobbies and preferences, residential areas, schools of origin, and “friends of friends” It is defined as providing a place to build new human relationships through connections with other people who have no direct relationship with them (see wikipedia “Social Networking Services”). The contents of the services are diverse, and according to wikipedia “List of social networking services”, they are classified into 20 types, and specific names and contents are listed. Table 1 shows a list of 20 types.

  However, these are all used in normal times, and do not provide and use real-time information such as emergency, disaster, sudden change in weather, roads associated with these, and traffic conditions. If there is a system that can provide and use each other in real time, the information recognized by the driver on the spot, it is possible to know sudden changes in road conditions due to weather and road information at the time of accidents and disasters. It is convenient because it can avoid expansion and secondary disasters.

  In addition to traffic conditions, road traffic information includes road surface conditions, accidents, falling objects, dangerously driven vehicles, tunnel fires, avalanches, landslides, poor visibility due to volcanic ash and snowstorms, cracks, road collapses, and bridge damage. , Flooding, liquefaction, river flooding, tsunami, explosions, tornadoes, riots, terrorism, etc., all information necessary for driving safety is included. As well as ensuring safety, traffic congestion and secondary disasters can be avoided. The system 1 provides a social networking service that allows drivers to share in real time road traffic information specialized for their area servers that is necessary for driving safety.

  When the information distribution service by this system 1 is performed by a car navigation maker or a car maker equipped with navigation, access to the center server 3 is permitted without access using the navigation ID transmitted from the in-vehicle terminal device 2 side. be able to. When other persons operate, a charging system may be used, or access may be free on condition that pre-registration from the in-vehicle terminal device 2 is performed. In the latter case, it can be operated by putting a commercial on the site screen or by voice during distribution.

Next, the in-vehicle terminal device 2 used in the present system 1 will be described in order with reference to FIGS.
(First embodiment of in-vehicle terminal device)
In the first embodiment, as shown in FIG. 4, as the in-vehicle terminal device 21, a smartphone-type mobile terminal (hereinafter referred to as “mobile terminal”) mounted on a desktop holder (cradle) 210 installed on a dashboard. 211 is used. If it carries out like this, this system 1 can be utilized, charging the smart phone type portable terminal 211 with the battery of a car, and even if it uses for a long time, a power supply will not turn off.

  As shown in FIG. 5, the portable terminal 211 of the present embodiment wirelessly communicates with the base station 5 of the mobile communication network based on the position detection device 61, the microphone 62, the smartphone application 63, the touch panel 64, and the public telephone line protocol. Dedicated application software (dedicated to access the communication module 65 to be connected and the website provided by the center server 3 of the system 1 (named “road traffic information SNS site” for short) Application 66), and a dedicated OS 67. Similar to existing smartphones, in addition to the telephone function and e-mail function, it has a function that allows free Internet connection like a personal computer (PC) using the touch panel 64 provided integrally with the display unit. A feature of the OS 67 is that it can connect to two sites at the same time. The position detection device 61 receives radio waves from a satellite by GPS (Global positioning system), and detects the position (latitude, longitude) of the mobile terminal 211. The smartphone application 63 refers to any application that can be used on the smartphone, such as connection to the Internet and reproduction of music recorded on the smartphone. The public line network used by the communication module 66 is a mobile communication network.

  As shown in FIG. 6, the dedicated application 66 includes a site access unit 651, a voice recognition unit 652, a voice generation unit 653, a format conversion unit (CODEC) 654, a data compression / decompression unit 655, a packet generation unit 656, data Transmission means 657 is included. In the dedicated application 65, an address (URL) of a road traffic information SNS site and a voice keyword are associated and registered. The speech keyword is, for example, “Dorojo Hosite”.

  The driver attaches the portable terminal 211 to the cradle 210 at the time of departure, connects to a navigation site, selects guidance based on current location display or route search, and departs to a destination such as Nikko while using the navigation function. Suppose a driver finds a vehicle fire and a subsequent evacuation vehicle ahead due to a multiple rear-end collision that would have occurred on the way, down the Tohoku Expressway, and near the entrance of the Hasuda parking area. The driver evacuates to the roadside belt while ensuring safety, touches the road traffic information SNS site connection icon displayed on the screen of the portable terminal 211, starts the dedicated application 66, and then uses the voice keyword. Access the road traffic information SNS site and upload road traffic information. Hereinafter, an information upload procedure executed by the processor of the portable terminal 211 by the dedicated application 66 will be described with reference to FIG.

<Uploading information>
When the dedicated application 66 is activated, a connection icon is displayed large. In this state, by inputting a voice keyword (“Dolo Joe Hosite”) from the microphone 62 of the mobile terminal 211, an instruction to access the site (center server 3) is given (ST10: yes). This is recognized, and the road traffic information SNS site is accessed according to the registered address (ST11). When the connection to the road traffic information SNS site is permitted (ST12: yes), the function of the dedicated application 66 allows the “distribution request”, “ Two selection menus of “information provision” are displayed. The selection menu may be displayed in an overlapped manner with the navigation screen (map) that has already been activated, or may be displayed in parallel with the map by dividing the screen into two on the left and right. In this way, the operability is good, and the driver can confirm that he is connected to the road traffic information SNS site while using the navigation function. The mobile terminal 211 has a unique IP address for receiving access and distribution to the road traffic information SNS site.

  When the menu screen is displayed, the dedicated application 66 provides voice guidance “Please select a menu” (ST13). When the driver selects the menu by voice input, “Joe Hotekyo”, and the dedicated app 66 recognizes this (ST14: yes), “Information is accepted. Please enter the area, road name or location.” Reply (ST15). Here, “region” means a certain range in which a specific road or place cannot be designated, for example, “near XX”, and “road name or place” means, for example, “national road 120 A location that can be identified, such as “Yamatocho intersection on Route Line” or “In front of XX City Hall”.

  If the driver inputs “Tohoku Expressway, near the entrance of Hasuda parking area” and the dedicated application 66 cannot correctly recognize the input voice, the driver is prompted again (ST16: no). If it can be recognized (ST16: yes), it will be notified by voice saying "Please enter the recognized status" (ST17). When the driver continues to input “Multiple rear-end collision detected. A vehicle fire has occurred.”, The dedicated app 66 repeats the recognized content (ST18) and asks the driver, “That ’s all right. "Wow?" If there is a “No” response, the user is again instructed to enter the authorized location (ST19: no). The content to be uploaded to the center server 3 as the recognized information is “where and what has happened”. As described above, since “where” and “what happened” are input independently, necessary information can be accurately picked up.

  If there is no mistake in the content of the repetition and the answer is “Yes” (ST19: yes), the dedicated application 66 uses the information input about “where” and “what” to the RAM (not shown) of the portable terminal 211. To temporarily store each (ST20). After all the contents have been input, the information stored in the RAM is converted into an audio file format (digital value) (ST21), and these are converted into file data as a single packet as a transmission unit (ST21) ST22). A file number is written in each file data. File 1 is a “location” file, and file 2 is a “verification status” file. Each file data should be compressed. The input information is transmitted by the public telephone line communication module 65 as a packet to the center server 3 via the base station 6 of the mobile communication network (ST23). The dedicated application 66 adds a transmission time, a terminal ID, and a position (latitude, longitude) of the portable terminal 211 at the time of data transmission at the time of transmission. When the transmission is completed, the connection with the center server 3 is blocked. These processes are executed by each unit of the dedicated application 66 described with reference to FIG.

  Next, a data processing procedure executed by the processor on the center server 3 side using application software of the center server 3 will be described. When the center server 3 receives the information transmitted from the in-vehicle terminal device 211, the management server attaches a management number to the information and stores it in the center server 3, and as shown in FIG. , Reception time, transmission time of mobile terminal 211, transmission position (latitude, longitude), transmission area, terminal ID, and IP address of mobile terminal 211 are managed as an “information provision table”. The “sending area” refers to another prefecture determined from “sending position (latitude, longitude)”. The center server 3 transfers the information uploaded from the in-vehicle terminal device 21 to the server (area server 4) of each prefecture in the “transmission area”. The area server 4 in each prefecture stores the file data transferred from the center server 3 and manages the information using the “information provision table” similar to the center server 3.

  When the center server 3 receives a delivery request, which will be described later, from each in-vehicle terminal device 21, as shown in FIG. , The reception time, the current position (latitude, longitude) of the mobile terminal 211, the current area, the terminal ID, and the IP address of the mobile terminal 211 are entered. The mobile terminal 211 that has made the distribution request transmits the current position to the center server 3 while driving (for example, every minute), and the center server 3 transmits the “current position” and the “current position” in the “distribution request table”. Update "Area" from time to time. The “current area” refers to another prefecture determined from the “current position”. The center server 3 notifies the server (area server 4) of each prefecture in the “current area” that there is a delivery request from each in-vehicle terminal device 21. As with the center server 3, the area server 4 records the distribution request status in the “distribution request table” and manages it. When the “current area” is changed from Tokyo to Kanagawa with the movement of the automobile, for example, the center server 3 notifies the Kanagawa area server 4 that the in-vehicle terminal device 21 is requested for distribution, and Kanagawa The area server 4 records and manages this. As with the center server 3, the distribution request status is recorded in the “distribution request table” and managed. At the same time, the center server 3 notifies the Tokyo area server 4 transferred earlier that the “current area” has been changed to Kanagawa. In the area server 4 in Tokyo, the “current area” of the “delivery request table” is changed to Kanagawa. The area server 4 of each prefecture sends the road traffic information ("where" and "what happened") transferred from the center server 3 to all in-vehicles whose "current area" is the prefecture in the "distribution request table". The packet is delivered to the terminal device 21 in packets.

  In order to receive the distribution of the road traffic information, the dedicated application 65 is activated by touching the road traffic information SNS site connection icon displayed on the display screen of the portable terminal 211 at the time of departure. Then, the voice keyword is used to access the center server 3 of the road traffic information SNS site, and the voice of “Hi Shin Seiku” is input while the menu selection screen is displayed. When the dedicated application 66 recognizes this (ST14 in FIG. 7: no), it responds with a voice saying “We have received a request for distribution”, and the distribution request code includes the calling time, terminal ID and mobile terminal at the time of data transmission. A position 211 (latitude, longitude) is added and transmitted, and the center server 3 is requested for distribution. Even if the transmission is completed, the connection with the center server 3 is not cut off. This is for receiving delivery.

  As a result, the in-vehicle terminal device 21 can receive the distribution of road traffic information relating to the current prefecture from the area server 4. Distribution is continued until the connection with the center server 3 is interrupted. At the time of distribution, for example, it may be guided by adding a time such as “current information at 13:50”. As voice, voice synthesized data attached to the application software of the area server 4 may be used. Distribution may be made by unilaterally deciding on the side of the area server, such as every 5, 10, 15, or 30 minutes, in a pack of multiple pieces of information related to the area. The time interval may be arbitrarily selected. Note that the dedicated OS 67 may be configured so that the voice output of both sites can be set separately so that the guidance voice of the navigation site and the voice of the delivery from the road traffic information SNS site are not mixed.

  Upon receiving the distribution, the in-vehicle terminal device 21 separates the distributed packet data into the file 1 and the file 2 by the dedicated application 66, and decompresses each file data. Then, it is possible to hear “where” and “what has happened” from the microphone 62 by performing reverse format conversion (decoding, ie, conversion into analog audio). This audio is a reproduction of the raw audio provided.

  Information delivered in packs may be announced mechanically in the order received, in principle, but a specialized operator who manages information is placed in each area, and the file data is temporarily converted into text information or It may be converted into voice information, urgency judgment (content weighting) may be performed, and emergency and serious matters related to human life such as tsunami and landslide may be distributed with priority over other information. Alternatively, special information such as “emergency information” may be added. In addition, after confirming the accident processing or the like, the obsolete information may be deleted from the distribution target. In addition, when multiple pieces of the same identification information are collected from different drivers, it is efficient to distribute only one of them. Further, when the transmission position and the recognized position are remarkably separated from each other, it may be determined that there is no credibility, and may be excluded as a gusseter. In this case, the matter may be deleted from the “distribution request table” or may be excluded from the distribution target by setting a flag. Also, commercials, music, news, sightseeing spot guidance, etc. may be played by voice between distributions.

  It is more efficient if the navigation site supervises the information distribution service of the system 1. In this case, the mobile terminal 211 is sufficient with the existing OS of the smartphone (it may not be possible to connect to two sites simultaneously). In this way, on the navigation screen, not only traffic jam information, but also various road traffic information provided by the road traffic information SNS site can be displayed with icons, color markers, etc., by urgency level, by type, It is effective.

It should be noted that when the mobile terminal 211 is activated, both the navigation site connection icon and the road traffic information distribution SNS site connection icon may be displayed. Even while the navigation site is connected, the road traffic information distribution SNS site connection icon is displayed small in the upper right corner of the screen so as not to interfere with the navigation screen. When the provision of information ends, the connection to the road traffic information distribution SNS site is blocked, the map returns to its original state, the selection menu is erased from the screen, and similarly, the road traffic information distribution SNS site connection icon is displayed on the upper right of the screen. Display small in the corner. When a distribution request is made, the connection to the site is maintained as it is, but the menu screen is reduced so as not to interfere with the map display and to indicate that it is connected to the site and receiving distribution. And display small in the upper right corner. The distribution is ended by touching the x mark on the menu selection screen. When providing information during distribution, the user can touch the menu screen excluding the x mark, enlarge the menu screen, select “Provide Information”, and so on.
(Second embodiment of in-vehicle terminal device)
Next, a second embodiment of the in-vehicle terminal device will be described. In this embodiment, a car navigation system having an Internet connection function is used as an in-vehicle terminal device. Specifically, as shown in FIG. 10, the in-vehicle terminal device 2 is connected to a base station of a mobile communication network based on a position detection device 71, a gyro 72, map data 73, a microphone 74, and a public telephone line protocol. A car navigation system (car navigation) 221 including a communication module 75, a dedicated application 76, and voice recognition means 77 is used. The position detection device 71 and the communication module 75 are the same as those in the first embodiment. The gyro 72 is for detecting the direction of the east, west, south, and north of the automobile and reflecting it in the navigation map. The car navigation system 221 that is the in-vehicle terminal device 22 is customized using the dedicated application 76 so that the system 1 can be used. The dedicated application 76 of the present embodiment differs from the dedicated application 66 of the first embodiment in that the voice recognition means 77 of the car navigation system 221 replaces the voice recognition means of the dedicated application 76. The voice recognition means may be provided in the center server 3.

  The initial screen when the car navigation system 221 that is the in-vehicle terminal device 22 is activated displays a navigation operation menu on the screen and displays an icon for connection to the road traffic information SNS site in the upper right corner of the screen. The operation of the car navigation system 221 may be performed using a remote controller, or may be performed by voice through the microphone 74 using the voice recognition unit 77. Or you may make it carry out with a touchscreen.

  The map is displayed using the map data 73 preinstalled in the hard disk drive of the car navigation system 221. When the destination is entered by the facility name, telephone number or address in the operation menu of the car navigation system 221, the communication module 75 is displayed. The destination is searched using the latest data on the server side of the navigation site, and the route to the destination is set on the screen of the car navigation system 221. When the map data is updated on the site side, the latest map data (difference) is distributed and installed from the server to the car navigation system 221 by background processing while using the car navigation system 221. When the route is set, the connection with the navigation site is cut off, and the car navigation system 221 itself provides guidance to the destination thereafter. The icon for connecting to the road traffic information SNS site is displayed in the upper right corner of the screen even when the car navigation system 221 is used.

  When requesting information provision or delivery to the road traffic information SNS site on the way to the destination, an icon for connection to the road traffic information SNS site displayed in the upper right corner of the screen of the car navigation system 221 is displayed. Touch to activate the dedicated application 76. When activated, the icon is enlarged and displayed on the screen.
