  In a device such as a car navigation system that presents information mounted on a moving body, it is possible to present information more accurately according to the external situation by obtaining real-time information from the outside. Thereby, the convenience for the user can be improved. For example, in searching for the optimum route of a car navigation system, it is possible to improve the accuracy of the search by obtaining information on traffic obstacles occurring ahead in a timely manner.

  In that case, “how to transmit information from outside in real time” becomes a problem. In consideration of communication cost and ease of communication, broadcast communication by a broadcasting system is appropriate for information transmission to a large number of mobile objects. This method is sufficient to transmit the same information to all mobile objects.

  However, depending on the contents, it is also necessary to limit the destination moving body.

FIG. 18 is a diagram illustrating a configuration of a traffic information editing apparatus and an information providing system including the traffic information editing apparatus according to an embodiment of the present invention. In FIG. 18, reference numeral 10000 denotes a traffic information editing apparatus that edits and holds restricted traffic information, and 10100 denotes a restriction information input unit that inputs road restriction information 10200 and event restriction information 10300. 11000 is a communication base station that transmits regulated traffic information, and 12000a is the same vehicle that receives the regulated traffic information, and is traveling so as to pass through the positions 12000b and 12000c. Further, 13000 is a GPS (Global Positioning System) satellite, and 14000 is an information receiving device that receives restricted traffic information on the vehicle side.

In this embodiment, a regulated traffic information database (hereinafter referred to as DB) 10400 is edited by a traffic information editing device 10000, and regulated traffic information is transmitted wirelessly to a vehicle 12000a via a communication base station 11000. 12000b and 12000c points where the information receiving device 14000 included in 12000a receives the restricted traffic information and satisfies the necessary conditions for providing the restricted traffic information with the traffic information editing device 10000, position, direction, period, and information provision This is a traffic information system that notifies the driver of regulated traffic information at the timing when the vehicle arrives.

First, the traffic information editing apparatus 10000 will be described. The purpose of the traffic information editing apparatus 10000 is to create the regulated traffic information in the form of electronic data that can be transmitted by communication, and hold the regulated traffic information DB 10400 so that it can be output as necessary. Of the restricted traffic information, the road restriction information 10200 is information on road signs and road restrictions, and static warning information on roads. Information relating to road signs and road regulations in the road regulation information 10200 can use a digital traffic regulation DB created by the Japan Traffic Management Technology Association. Information that is insufficient in the digital traffic regulation DB or information that is newly updated is set so that it can be added by the regulation information input unit 10100. Examples of static alert information include accident point notifications at past accident points, alert information for accident prevention calls, traffic volume on roads and intersections, travel speed statistics, and risk analysis information based on sensor information, roads For example, forward-looking information based on the shape and alert information about the curve shape. The event regulation information 10300 is information on traffic restrictions and warnings required due to the occurrence of an event. For example, information related to traffic restrictions that occur in real time, such as traffic prohibition and traffic restrictions associated with construction and events, traffic restrictions associated with changes in weather, and alert information. The road regulation information 10200 and the event regulation information 10300 are manually input by a traffic manager or automatically input by a device that has collected the regulated traffic information. The restriction information input unit 10100 adds to the road restriction information 10200 and event restriction information 10300 the position, direction, period, and information provision conditions for providing information to the driver. There are two ways of providing information providing positions: points given according to the type of regulated traffic information and those given in sections. For example, if the restricted traffic information is temporary stop information, a certain point in front of the intersection where the temporary stop is required is given as an information providing point, and if the restricted traffic information is speed restriction information, the speed restriction continues. A section is given as an information provision section. The direction in which information is provided is determined in relation to the traveling direction of the road. As for the location and direction of information provision, information is provided at an effective timing, such as by providing the driver with advance notice of the regulated traffic information by determining the location and direction where the regulated traffic information should be actually observed independently. Is possible. As for the period for providing information, it is assumed that the same daily time zone, daily limit, monthly limit, indefinite period, period, etc. can be freely input. Information provision conditions include vehicle type or speed conditions. For example, if the restricted traffic information is speed restriction information, a speed limit is set according to the vehicle type, and a condition for giving a warning of overspeed only to vehicles that exceed the speed limit is added. In addition, when the regulated traffic information is accident statistical information limited to a vehicle type, for example, if it is alert information at an intersection where large vehicle accidents occur frequently, a condition for providing information only to large vehicles is added. When the traffic manager inputs the road regulation information 10200 and the event regulation information 10300, a GUI as the regulation information input unit 10100 is used to easily enter the information provision position, direction, period, and information provision conditions.
A map display device using (Graphical User Interface) and editing means on the map are provided. Automatically input road regulation information 10200 and event regulation information 10300, and regulate traffic information
When registering in DB10400, for example, when registering traffic volume and speed statistics, the statistical information compiled and analyzed by other information collection devices is used as input, according to the rules or settings for creating information provision conditions in advance. The conditions for providing information, such as position, direction, period, and target vehicle type are added. Regulated traffic information accompanied by information provision position, direction, period, and information provision conditions is stored in the regulated traffic information DB 10400.

Next, the flow until the regulated traffic information is notified to the driver will be described. The restricted traffic information 10400 is delivered to the communication base station 11000 in whole or in part. The amount of information held by the communication base station is also changed according to the size of the communication area in charge of the communication base station. In the example of FIG. 18, the communication base station 11000 establishes communication with the information receiving device 14000 (cellular phone in the example of the figure) equipped in the vehicle 12000a, and transmits the restricted traffic information held by the communication base station 11000. The vehicle 14000 holds the received restricted traffic information, acquires vehicle position information by the GPS satellite 13000, and each restricted traffic information satisfies the position, direction, period, and information provision conditions specified by the restricted information input unit 10100. Notify the driver of regulated traffic information at the appropriate timing. When the vehicle 12000a is at the point 12000b, the driver is notified of the information on the temporary stop to be provided at the position and direction at the point 12000b, and the temporary stop information is prompted. When the vehicle is at the point 12000c, the vehicle 12000a issues an overspeed warning to the driver if the position and direction at the point 12000c, the speed of the vehicle 12000a, and the provision conditions of the speed regulation information to be provided by the vehicle type match. Encourage you to observe the speed limit.

  FIG. 19 is a diagram showing another embodiment of the information providing system of the present invention. The absolute position measuring device 20100 is a device that measures the absolute position of the vehicle 20000 in real time using a GPS (Global Positioning System). The absolute position measurement device in the present embodiment uses GPS using a GPS satellite 13000 as an absolute position measurement device. However, autonomous navigation, a method using map matching, or a method using the method and GPS in combination. May be used. The road regulation information DB 203 takes out the road regulation information from the regulation traffic information DB 10400 created by the traffic information editing apparatus 10000 using a storage medium such as a CD-ROM, CD-R, DVD-ROM, and flash memory, and stores it in the vehicle. It is held. The storage medium is installed in the vehicle in such a way that road regulation information can be read by an instruction from the information control unit 20400 (reading device corresponding to each storage medium such as a CD-ROM drive). Although the road regulation information held by the storage medium becomes obsolete as time passes, the driver can update the road regulation information DB 20300 by periodically replacing the road regulation information with a new storage medium. The information control unit 20400 integrates various information of the absolute position, direction, speed, time, and road regulation information of the vehicle, and sends road regulation information to the driver 20500 at a designated timing or a timing calculated by the information control unit 20400. It is an apparatus provided with a means for notification.

  This embodiment is a system completed with a single vehicle, and includes an absolute position measurement device 20100, a direction calculation unit 20200, a speed acquisition unit 20500, and a time acquisition unit 20600, and is calculated by a designated timing or information control unit 20400. It is characterized by notifying the driver 20500 of road regulation information at the timing.

  Note that the current point or region or the future point or region in the broadcasting method shown in FIG. 1 may be obtained from the information control unit 20400.

  FIG. 20 is a flowchart showing the flow of processing for notifying the driver of road regulation information in the embodiment of FIG. The processing flow in the embodiment of FIG. 19 will be described below using the flowchart of FIG.

First, in step 31000, information regarding the current state of the vehicle 20000 is acquired by each device of the vehicle 20000. The absolute position information of the vehicle 20000 is acquired by the absolute position measuring device 20100. The speed acquisition unit 20500 acquires the traveling direction speed of the vehicle 20000. The speed can be calculated using a vehicle speed sensor or an absolute position measurement device 20100 provided in the vehicle 20000. The time acquisition unit 20600 acquires the current time using a clock provided in the vehicle 20000. Next, in step 32000, the absolute position information acquired by the absolute position measurement device 20100 is used as input, and the direction calculation unit 20200 calculates the traveling direction of the vehicle 20000. The information control unit 20400 acquires information on the absolute position, the traveling direction, the traveling direction speed, and the time obtained in the above two steps. Further, it is assumed that the information control unit 20400 has vehicle type information of the vehicle 20000 in advance. In step 33000, the information control unit 20400 uses the acquired vehicle absolute position, traveling direction, traveling direction speed, time, and various conditions that specify information provision of each road regulation information (information provision position, direction, period, and road). The conditions defined for each regulation information) are compared, and the road regulation information corresponding to the provision of information is extracted from the road regulation information DB 20300. In step 34000, the road regulation information extracted by the information control unit 20400 is notified to the driver. By periodically repeating the processing from step 31000 to step 34000, it becomes possible to provide information continuously at a good timing. The information control unit 20400 can also newly calculate the information provision timing using the specified information provision position and information provision conditions of the road regulation information DB 20300. For example, in the case of a temporary stop, provision timing is calculated according to the speed of the vehicle. The vehicle stoppable position is calculated from the current vehicle speed and the vehicle deceleration performance, and compared with the position where the temporary stop should be executed. When the distance between the stoppable position and the temporary stop position is smaller than a predetermined distance, a temporary stop warning is given to the driver. Thus, it is possible to adjust the information provision timing according to the difference in the driving operation of the driver.

  Step 51000 is processing outside the vehicle. The communication base station 40000b receives the restricted traffic information from the traffic information editing device 10000 and holds it as the restricted traffic information DB 40200b. When narrow-area communication is used, since the position and direction on the road can be defined at the time of installing the communication base station, the restricted traffic information DB limited to the position and direction of the communication base station can be distributed. By holding the required amount of regulated traffic information DB for each communication base station, it is possible to reduce the capacity of the storage medium included in the communication base station. Step 52000 and subsequent steps are processing on the vehicle side. In step 52000, the vehicle 41000b entering the narrow area wireless communication area of the communication base station 40000b receives the contents of the regulated traffic information DB 40200b via wireless communication between the information receiving unit 41100 and the LCX 40100b. The received restricted traffic information is stored in the restricted traffic information DB 41200 by the information receiving unit 41100. The processing after step 53000 is the same as the processing after step 31000 in FIG. 20, and the information control unit 41300 acquires the absolute position, traveling direction, traveling direction speed, and time of the vehicle, and regulates regulated traffic information that matches the conditions. The information is extracted from the traffic information DB 41200 and notified to the driver at the timing when the extracted regulated traffic information is designated or calculated by the information control unit 41300. The process of step 51000 is executed when the restricted traffic information related to the communication base station 40000b is changed in the restricted traffic information DB 10400, and the process of step 52000 is executed when communication between the vehicle 41000b and the communication base station 40000b is established. And the process after step 53000 is periodically executed in the vehicle. By periodically repeating the processing from step 53000 to step 56000, it becomes possible to provide information continuously at a good timing.

  FIG. 24 is a flowchart showing the flow of processing for notifying the driver of regulated traffic information in the embodiment of FIG. The processing flow in the embodiment of FIG. 23 will be described below using the flowchart of FIG.

Step 71000 is processing outside the vehicle. Similar to step 51000 in FIG. 22, regional traffic information is distributed for each base station. Steps 72000 and 73000 are preprocessing on the vehicle side when communication is established between the mobile communication base station 60100b and the information transmission / reception unit 61100 on the vehicle side. In step 72000, vehicle 61000b acquires various types of vehicle information using absolute position measurement device 20100, speed acquisition unit 20500, and time acquisition unit 20600. In addition, the vehicle type information is held in advance in the vehicle. In step 73000, direction calculation unit 20200 calculates the traveling direction of the vehicle. In step 74000, the information transmission / reception unit 61100 transmits the various vehicle information, the traveling direction, and the vehicle type information to the base station 60000b. Step 74000 is processing in the base station 60000b. In step 75000, the base station 61000b extracts the restricted traffic information limited by the received vehicle information from the restricted traffic information DB 60200b, creates the restricted traffic information DB 60300b, and transmits it to the vehicle 61000b. Alternatively, the regulated traffic information DB60200b is classified in advance and the regulated traffic information
The DB 60300b is created, and the regulated traffic information DB 60300c suitable for the received vehicle information is selected and transmitted to the vehicle 61000b. By defining the classification criteria for creating the regulated traffic information DB 60300c by the position, traveling direction, and type of vehicle, it is possible to reduce the amount of information communicated at one time. The processing after step 76000 is the same as the processing after step 52000 in FIG. 22, the regulated traffic information received by the vehicle is stored in the regulated traffic information DB 61200, and the information control unit 61300 displays the absolute position, the traveling direction, and the traveling of the vehicle. The direction speed and time are acquired, the regulated traffic information that matches the conditions is extracted from the regulated traffic information DB 61200, and the extracted regulated traffic information is notified to the driver at the designated timing or the timing calculated by the information control unit 61300. In the process of step 71000, the restricted traffic information related to the communication base station 60000b is the restricted traffic information.
This process is executed when the change is made in the DB 10400, and the processes in steps 72000 and 73000 are periodically executed in the vehicle in the same manner as the processes after step 76000. Steps 74000 and 75000 are executed when communication between the vehicle 61000b and the communication base station 60000b is established. The communication is established when the vehicle passes under the optical beacon when the information communication means limited to the position such as the optical beacon is used. When information communication means that does not limit the position, such as a cellular phone, is used, communication connection is made at regular time intervals or communication is always established.

FIG. 25 is a diagram showing another embodiment of the information providing system of the present invention, which is an example using multi-channel broadcasting as a communication means between a communication base station and a vehicle. 80000a is a communication base station for satellite digital broadcasting, and includes a broadcasting station 80100a and a communication satellite 80200a. Similarly, 80000b is a terrestrial digital broadcast or FM multiplex broadcast communication base station, and the broadcast station 80100b transmits regulated traffic information. The regulated traffic information 80200b transmitted by the broadcasting station 80100b is classified for each channel by position, traveling direction, and vehicle type, and is assigned regulated traffic information. The regulated traffic information to be transmitted takes the same form at the communication base station 80000a. In this embodiment, broadcast communication using satellite digital broadcast, terrestrial digital broadcast, and FM multiplex broadcast is cited as multichannel broadcast, but other multichannel broadcast communication means may be used. Reference numerals 81000a and 81000b denote vehicles traveling in the area A and the area B, respectively.

  FIG. 26 is a flowchart showing the flow of processing for notifying the driver of road regulation information in the embodiment of FIG. The processing flow in the embodiment of FIG. 25 will be described below using the flowchart of FIG.

Steps 91000 and 92000 are processes outside the vehicle. In step 91000, the communication base station 80000b receives the restricted traffic information DB 10400 from the traffic information editing device 10000. If the information distribution range of the communication base station 80000b is limited to a specific area, the restricted traffic information of the corresponding area is received. In step 92000, the communication base station 80000b classifies the restricted traffic information, assigns it to each channel, and transmits it on the broadcast wave. The processing after Step 93000 is processing inside the vehicle. In step 93000, the vehicle 81000b acquires various types of vehicle information by the absolute position measurement device 20100, the speed acquisition unit 20500, and the time acquisition unit 20600. In step 94000, information receiving unit 81100 selectively receives the regulated traffic information of the appropriate classification in regulated traffic information 80200b by matching the channel for receiving the broadcast wave based on the vehicle information in step 93000.

The process of step 91000 is executed when the restricted traffic information related to the communication base station 80000b is changed in the restricted traffic information DB 10400. The process of step 92000 is always repeatedly executed in the communication base station 80000b. Steps 93000 and 95000 and subsequent steps are always repeatedly executed in the vehicle. Step 94000 is performed when the broadcast wave channel received by the vehicle changes, that is, the position and traveling direction of the vehicle are on the broadcast wave channel. Executed when entering another category.

  FIG. 27 is a diagram showing another embodiment of the information providing system of the present invention. By combining communication means for transmitting vehicle information to a base station and multi-channel broadcasting communication means, the vehicle It is an example which implement | achieves individual information provision. The base station 13000a is a broadcast satellite communication means capable of bidirectional communication, the base station 13000b is a terrestrial broadcast communication means, and the vehicle 13100b is provided with information communication means to the base station 13000b. The present embodiment is characterized in that each vehicle information is transmitted to the base station, and the vehicle can receive the regulated traffic information corresponding to each vehicle.

  In the processing on the vehicle side, information on the position, direction, and vehicle type of the vehicle is acquired as shown in the previous embodiment, and the vehicle information is transmitted to the base station using communication. On the base station side, regulated traffic information to be provided on the vehicle side is extracted based on the transmitted information. The extracted regulated traffic information is placed on a channel assigned to each vehicle and transmitted to the vehicle. The rest of the processing is the same as in the previous embodiment, and the received regulated traffic information is stored and provided to the driver at a designated timing or a timing calculated on the vehicle side.

  Note that the broadcasting apparatus and the broadcasting method shown in FIG. 1 may be used as the broadcasting method shown in FIGS. In that case, an information communication path can be formed so as to select received information according to the current movement status of the vehicle and a future movement schedule, and information storage device associated with realizing appropriate information transmission to each vehicle The capacity can be reduced.

  FIG. 28 is a diagram showing another embodiment of the information providing system of the present invention, and is an example of performing version management of road regulation information. 100000 is a traffic information editing device that holds version information when inputting road regulation information. The present embodiment is characterized in that the latest information is held in the vehicle while reducing the amount of information communication by performing version management of the road regulation information DB 100100.

  First, in order to hold the road regulation information DB 100600 in the vehicle, it has a mass storage device that can hold all the road regulation information of the region where the vehicle travels or a device that can read a mass storage medium. Think about the case. Reference numeral 100300 denotes a storage medium that holds the road regulation information DB 100100, which is a large-capacity storage medium such as a CD-ROM, DVD-ROM, or DVD-RAM.

  FIG. 29 is a flowchart showing the flow of processing for updating regulated traffic information in the embodiment of FIG. The processing flow in the embodiment of FIG. 28 will be described below using the flowchart of FIG.

Step 110000 is processing in the traffic information editing apparatus 100000. When the road regulation information is changed, it is stored in the road regulation information DB 100100, and the latest version information 100700 and information on the changed portion of the road regulation information accompanying the version change are used as the change difference information 100800, and the communication base station 100200. Deliver to. Further, the traffic information editing apparatus 100000 periodically saves the road regulation information DB 100100 to which the version information is added in the storage medium 100300. The vehicle 100400 holds the storage medium 100300 in advance and incorporates it into a reading device (CD-ROM drive in the case of a CD-ROM) corresponding to the storage medium so that it can be read as the road regulation information DB 100600. As for the event regulation information, the information edited by the traffic information editing device 100000 is distributed to the communication base station 100200 as event regulation information 100500 in a form in which the provision position and direction are designated. Step 110100 is processing in the communication base station 100200. The communication base station 100200 transmits the event restriction information 100500, the road restriction information version information 100700, and the change difference information 100800 to the vehicle 100400 using wireless communication. Step 110200 and subsequent steps are processing in the information receiving unit 101000 of the vehicle 100000. In step 110200, the information receiving unit 101000 receives the version information 100700 and the event regulation information 100500. At this time, if the version information in the road regulation information DB 100600 is equal to the version information 100700, the process proceeds to step 110300, and if the version information is different, the process proceeds to 110400. In step 110300, the received event regulation information 100500 is temporarily stored as event regulation information 100900. Since the event regulation information 100900 is traffic information with high real-time properties, a RAM or a hard disk is used as a storage device, and is erased from the storage device when the provision period in the event regulation information 100900 has passed. In step 110400, in addition to the process of storing the event regulation information 100900 in step 110300, the change difference information 100800 is received and additionally stored in the road regulation information DB 100600 together with the version information 100700. At this time, if the storage medium 100300 is a writable storage medium (for example, DVD-RAM), the version information 100700 and the change difference information 100800 are directly written in the storage medium 100300 to update the version of the road regulation information DB 100600. If the storage medium 100300 is a non-writable medium (CD-ROM and DVD-ROM), it includes a hard disk as another writable storage device, and stores version information 100700 and change difference information 100800. However, as the road regulation information DB 100600, there is no distinction between the storage medium 100300 and the storage device, and it is handled as an integrated one. The processing after storing the restricted traffic information is the same as in the other embodiments, and when the vehicle exists at the position and direction where the information is provided, the relevant traffic restriction information is called and notified to the driver.

  In the present embodiment, road regulation information has a large capacity, but the update frequency is low, and event regulation information is real-time information, so that information stored in the vehicle and information using communication are separated. As a result, the amount of information communication can be reduced.

  In addition, an example of an information providing system in which the storage capacity in the storage device in the vehicle is small and the restricted traffic information, in particular, the road restriction information cannot be held all.

  The information that the vehicle obtains from the communication base station is information that is classified based on the position, direction, and vehicle type information transmitted by the vehicle, or regulated traffic information that is classified in advance for each position, direction, and vehicle type. It is assumed that version information is managed. On the vehicle side, it is assumed that the storage capacity of the storage device is held among the previously received restricted traffic information and version information. When the communication base station and the vehicle establish communication, and when the restricted traffic information is communicated from the communication base station to the vehicle information receiving unit, first, version information is transmitted. When the regulated traffic information having the same version information as the received version information is held in the vehicle, the regulated traffic information is not newly updated. When the regulated traffic information having the same version information as the received version information is not held in the vehicle, the regulated traffic information or the change difference information is received. At this time, if the storage capacity of the storage device in the vehicle is vacant, the vacant area is secured and retained as the received information area. If there is not enough free space in the storage device, keep the frequency of access to regulated traffic information classified by the vehicle, delete this less frequently regulated traffic information, and secure the deleted area as the received information area To do. In other words, by keeping as much information as possible about areas where vehicles frequently pass, we can minimize the update and delete information on areas where vehicles do not pass so much that they will not pass in the future. Even if there is little, it becomes possible to keep fresh information in the vehicle.

  FIG. 30 is an embodiment of information representation means in the vehicle for notifying the driver of traffic information.

Even when the absolute position measuring device does not exist, the display is updated every time the speed regulation information in the regulated traffic information acquired by communication is changed. As a result, the speed regulation information can be notified to the driver at an appropriate timing. The image 120400 is obtained by displaying road regulation information on the windshield 120200 by the projector 120300. The video 120400 is displayed while driving at a point or section where the road regulation information designated by the traffic information editing device is presented, and alerts the driver to safety. For example, temporary stop information is continuously displayed from a point given as an information providing position to a point where an actual stop sign exists. The character information display 120500 expresses the restricted traffic information in the form of character information and notifies the driver. The information display on the character information display 120500 is suitable for notifying information that is continuously warned in a certain section. For example, information on overtaking prohibition shown as a road sign or warning information in a continuous curve section is displayed. Suitable for presenting. The display 120006 displays regulated traffic information on a map. Information about road signs can be easily expressed by a map display. The speaker 120700 converts the traffic information into voice information and notifies the driver. The voice instruction is suitable for expressing information in which the provided position is represented by a point.

The information expression level adjustments 120800a and 120800b adjust the amount of information when notifying the driver by using one or a plurality of information expression means. The information expression level adjustment 120800a is an adjustment knob displayed on the display 120600. The information expression level adjustment 120800a described in the present embodiment has a knob shape, but other expression methods such as a table can be used. The information expression level adjustment 120800b incorporates an adjustment knob as a vehicle device. Both 120800a and 120800b are means for making it possible to adjust the presence or absence of display according to the attributes of the restricted traffic information notified to the place or the driver. For example, it is possible to specify and select conditions such as notifying only temporary stop information or notifying region B information from road regulation information. By providing the information expression level adjustment, the driver can receive information suitable for himself / herself.

  Here, processing of the receiving station of the own vehicle (own vehicle 3205, own vehicle 3210, own vehicle 3215) will be described. The own vehicle has a receiving station 3180, and a plurality of advertisement contents (advertisement contents 3300, advertisement contents 3400, advertisements) prepared for each user situation (route to advertisement provider, distance to advertisement provider) distributed from the distribution station. The content 3500) is received by the receiving device 3126. Then, the destination point / route / distance / vehicle type information extracting device 3130 extracts the destination point, the route to the destination, the distance to the destination, and the vehicle type information for the plurality of advertisement contents received by the receiving device 3126, respectively. Then, in the route calculation device 3148, the route to the destination and the distance to the destination are calculated based on the own point obtained by the own point take-out device 3144 and the destination point / route / distance / vehicle type information take-out device 3130. calculate. Next, in the comparison device 3146, whether the route to the destination obtained by the route calculation device 3148 is included in the route to the destination extracted by the destination point / route / distance / vehicle type information extraction device 3130, or the destination point Since it is determined whether the distance to the destination obtained by the route calculation device 3148 is included in the distance range to the destination extracted by the route / distance / vehicle type information extraction device 3130, and these conditions are satisfied. If so, the information selection device 3138 selects the advertisement content and displays it on the display device 3152.

First, consider the host vehicle 3205 when the distance to the advertisement provider 3220 (ΔΔΔ park) is in the vicinity of 50 km. If the route calculation device 3148 in the own vehicle 3205 calculates the route “Highway (3225) → National highway × Route (3235) → Prefectural road △ Route (3245)” to the destination and the distance 50 km to the destination, In the device 3146, the distance (3320, 3420, 3520) to the destination of each content and the route (3330, 3430, 3530) to the destination are compared with the calculation result (to the destination extracted from the advertising content 3300). The route “Expressway (3225) → National road × Line (3235) → Prefectural road ΔLine (3245)” is the route to the destination of the calculation result “Highway (3225) → National road × Line (3235) → Prefectural road ΔLine ( 3245) "and the distance from the distance 20 km to 60 km to the destination extracted from the advertising content 3300 is the calculation result. The information selection device 3138 selects the corresponding advertisement content 3300, and the advertisement information 3340 “(1) XX Inter (3230) on the display device 3152 (3235) XX Approximately 60 minutes in the city direction (traffic congestion near the interchange) (2) Δ △ From the interchange, display the national highway x route (3235) xx 50 minutes in the city direction.

Next, consider the own vehicle 3210 when the distance to the advertisement provider 3220 (ΔΔΔ park) is in the vicinity of 10 km. In the own vehicle 3210, the route calculation device 3148 uses the route “National road x Route (3235) → Prefectural road △ Route (3245)” to the destination and the distance 10 to the destination.
Assuming that km is calculated, the comparison device 3146 compares the distance (3320, 3420, 3520) to the destination of each content and the route (3330, 3430, 3530) to the destination with the calculation result (advertising content). The route “Highway (3225) → National highway × Route (3235) → Prefectural road ΔLine (3245)” to the destination taken out from 3400 is the route “National highway × Route (3235) → Prefectural road Δ to the destination of the calculation result. And the distance 2 km to 20 km to the destination extracted from the advertising content 3400 is included in the distance 10 km to the destination of the calculation result). Select advertisement content 3400, turn right at 1km XX town at advertisement information 3440 “(1) XX town intersection on display device 3152 “Congestion near intersection” is displayed.

Similarly, consider the own vehicle 3215 when the distance to the advertisement provider 3220 (ΔΔΔ park) is in the vicinity of 1 km. If the route calculation device 3148 in the own vehicle 3215 calculates the route “prefectural road Δ line (3245)” to the destination and the distance 1 km to the destination, the comparison device 3146 displays the distance ( 3320, 3420, 3520) and the route to the destination (3330, 3430, 3530) and the calculation result (the route to the destination extracted from the advertising content 3500 "National road x route (3235)-> prefectural road △ route ( 3245) ”includes the route“ prefectural road Δ line (3245) ”to the destination of the calculation result. The distance to the destination of 2km extracted from the advertising content 3500 is 1 km to the destination of the calculation result. And the corresponding advertisement content 3500 is selected by the information selection device 3138, and the display device 31 is selected. 2 on the advertisement information 3440 "the first parking: full car the second Parking: full car No. 3 Parking: full car 4th Parking: full car" to display.

  In this way, the user can select necessary information that differs depending on the vehicle position and route from the information distributed from the advertisement provider.

  Next, the way in which the route calculation device 3148 calculates the route to the advertisement provider will be described with reference to FIGS. 36 and 37. FIG. FIG. 36 is an example of calculating a route based on a road-road link relationship, and FIG. 37 is an example of calculating a route based on traffic regulation information.

  In FIG. 36, there are a general road 3630 and a highway 3620, which are three-dimensionally crossing at a point 3650, respectively. The general road 3630 and the expressway 3620 cannot be reached at a point 3650. When the own vehicle 3600 is traveling on the highway 3620, the right and left turns from the highway 3620 to the general road 3630 are not made at the point 3650 due to the link relationship between the road and the road when calculating the route. Further, when the host vehicle 3600 is traveling on the expressway 3620, the route calculation is not performed in the direction opposite to the traveling direction at the time of route calculation.

  In FIG. 37, the road 3710 and the road 3710 are connected by a T-shaped road 3730. And T-junction 3730 is prohibited to turn right. The own vehicle 3700 exists in front of the T-shaped road 3730 and cannot turn right on the road 3720. Therefore, the own vehicle 3700 calculates a route on a route that does not turn right onto the road 3720.

  That is, when calculating the route, it is necessary to consider the link relationship between the road, the traveling direction of the vehicle, traffic regulation information, and the like. By doing so, the user can acquire the optimum information according to the location, position, and route.

Next, an example in which advertisement content is provided for each target vehicle type (by engine type, by class such as light vehicle, ordinary vehicle, and large vehicle) will be described with reference to FIGS. Here is an example where the gas station selects the necessary advertising content according to the type of engine of the customer's vehicle (gasoline / diesel) or according to the class of the customer's vehicle (light vehicle, ordinary vehicle, large vehicle). is there. The advertising content distributed by the gas station includes advertising content 3800 for a target whose engine type is “gasoline”, advertising content 3900 for a target whose engine type is “diesel”, and a class “large car”. There are advertising content 4000 for the target and advertising content 4100 for the target whose class is “ordinary car”. The advertisement content 3800 describes engine type information 3810 “gasoline” and advertisement content 3820 “regular gasoline: ¥ 80 high-octane gasoline: ¥ 100”, and the advertisement content 3900 contains engine type information 3910 “light oil” and an advertisement. Content 3920 “Diesel engine: ¥ 60 Diesel engine friendly oil Z is now on sale” is described, and advertisement content 4000 includes class type information 4010 “Large car” and advertisement content 4020 “Car wash: ¥ 2000. Per car wash bucket present ”is described, and the advertisement content 4100 includes class type information 4110“ ordinary car ”and advertisement content 4120.
“Car wash: ¥ 1000 Tissue paper for normal car wash” is described.

  Here, a process of selecting the advertisement content based on the vehicle type information added to the advertisement content will be described. The vehicle type information related to the own vehicle is recorded in advance in the vehicle type table.

  For example, if the host vehicle is a large vehicle having a diesel engine, the vehicle information (engine type: diesel, class type: large vehicle) is described in the vehicle type information table 3150.

  When the advertisement content (3800, 3900, 4000, 4100) of the gas station is distributed from the distribution station 3170, the receiving device 3126 receives the advertisement content on the own vehicle (receiving station 3180) side, and the received advertisement content The vehicle type information is extracted from the inside by the destination / route / distance / vehicle type information extracting device 3130, and the extracted vehicle type information is compared with the vehicle type information in the vehicle type table by the comparison device 3146, and the comparison result is obtained by the information selection device 3138. The advertisement content is selected based on the content, and the content of the selected content is displayed on the display device 3152.

For example, consider a case where the vehicle is a large vehicle having a diesel engine. The own vehicle (receiving station 3180) receives the engine type information (3810, 3910) and class-specific information (4010, 4110) of the received advertisement content and the contents described in the vehicle type information table 3150 (engine type: diesel, class Type: large vehicle) (the engine type 3910 “diesel” in the received content 3900 matches the engine type “diesel” in the vehicle type information table 3150, and the class type 4010 “large vehicle” in the received content 4000 and vehicle type information. The information selection device 3138 selects an advertisement content 3900 related to a diesel engine and an advertisement content 4000 related to a large vehicle. Then, the display content 3200 “fuel price: ¥ 60 / L (light oil) car wash: ¥ 2000 right now, a car wash bucket present for a large car wash” is displayed on the display device 3152 (see FIG. 42).

Next, consider a case where the vehicle is an ordinary vehicle having a gasoline engine. The own vehicle (receiving station 3180) receives the engine type information (3810, 3910) and class-specific information (4010, 4110) of the received advertisement content and the contents (engine type: gasoline, class) described in the vehicle type information table 3150. Type: normal vehicle) (the engine type 3810 “gasoline” in the received content 3800 matches the engine type “gasoline” in the vehicle type information table 3150, and the class type 4110 “normal vehicle” in the received content 4100 matches the vehicle type information. The information selection device 3138 selects the advertisement content 3800 relating to the gasoline engine and the advertisement content 4100 relating to the ordinary vehicle in the table 3150. Then, the display device 3152 displays the display content 4300 “Fuel price: ¥ 80 / L (regular gasoline) Fuel price: ¥ 100 / L (high-octane gasoline) Car wash: ¥ 2000 Presently, a tissue paper present per ordinary car wash” (FIG. 43) Display).

  By doing so, the user can select necessary information that differs depending on the vehicle type from the information distributed from the advertisement provider.

  Next, consider a case where the advertisement provider is a parking lot. FIG. 41 is a diagram showing the arrangement of three advertisement providing sources and the contents of the information to be provided. The three advertisement providers are a first parking lot, a second parking lot, and a third parking lot, respectively, and the first parking lot 4420, the second parking lot 4440, and the third parking lot 4460 exist on the map 4400.

The parking status 4430 of the first parking lot includes, for each class type, an empty vehicle status 4432: “10 remaining units”, an empty vehicle status 4434: “full”, and an empty vehicle status 4436:
It is “full”, and the first parking lot distributes the above three advertisement contents (light vehicle status 4432 for light vehicles, empty status 4434 for ordinary vehicles, and empty status 4436 for large vehicles).

  The parking situation 4450 of the second parking lot is an empty situation of 4552: 10 vehicles of the size type “total width within 2.0 m, total length within 4.5 m, total height within 1.5 m”, and the second parking lot is 1 One advertisement content (empty status of vehicle with size type “total width within 2.0 m, total length within 4.5 m, total height within 1.5 m”) is delivered.

The parking conditions 4470 of the third parking lot are, according to the class type, light car empty conditions 4472: “2 remaining cars”, ordinary car empty conditions 4474: “19 remaining cars”, large car empty conditions 4476: “full” The third parking lot distributes the above three advertising contents (light car situation 4472 for light vehicles, empty situation 4474 for ordinary vehicles, and empty situation 4476 for large vehicles).

  The process of selecting the advertisement content based on the vehicle type information added to the advertisement content is the same as the above-described example of the advertisement content distribution at the gas station.

  Now consider the case where the vehicle is a mini vehicle with a total width of 1.2 m, a total length of 3.5 m, and a total height of 1.2 m. At this time, information on the own vehicle (size type: overall width 1.2 m, overall length 3.5 m, overall height 1.2 m, class type: light vehicle) is described in the vehicle type information table 3150.

The own vehicle (receiving station 3180) receives the class type information and size type information of the received advertisement content and the contents described in the vehicle type information table 3150 (size type: overall width 1.2m, overall length 3.5m, overall height 1. 2m, class type: light car) (the class type “light car” in the received content 4432 matches the class type “light car” in the car type information table 3150, and the class type “light car” in the received content 4472) And the class type “light vehicle” in the vehicle type information table 3150 match, and the size type of the received content 4432 “size within the overall width of 2.0 m, overall length within 4.5 m, overall height within 1.5 m”. Type “total width 1.2 m, total length 3.5 m, total height 1.2 m”). WARNING contents 4432 and advertisement content 4472, within the overall width 2.0m, within the full-length 4.5m, to select the advertisement content 4452 relating to the vehicle within the overall height 1.5m. Then, on the display device 3152, as shown in the map 4500 in FIG.
“First parking lot: 10 empty vehicles” 4520, “Second parking lot: 10 empty vehicles” 4540, and “Third parking lot: 2 empty vehicles” 4560 are displayed.

  Further, consider a case where the own vehicle is a normal vehicle having a total width of 1.8 m, a total length of 4.2 m, and a total height of 1.3 m. At this time, information on the own vehicle (size type: overall width 1.8 m, overall length 4.2 m, overall height 1.3 m, class type: ordinary vehicle) is described in the vehicle type information table 3150.

  The own vehicle (receiving station 3180) receives the class type information and size type information of the received advertisement content and the contents described in the vehicle type information table 3150 (size type: full width 1.8m, full length 4.2m, total height 1. 3m, class type: ordinary car) (class class “ordinary car” in the received content 4434 matches the class type “ordinary car” in the car type information table 3150, and the class type “ordinary car” in the received content 4474) And the class type “ordinary vehicle” in the vehicle type information table 3150 coincide with each other, and the size type of the received content 4432 is “size within width 2.0 m, length 4.5 m, height 1.5 m”.

  By doing so, the user can select necessary information that differs depending on the vehicle type from the information distributed from the advertisement provider.

  Next, an example in which a railway company provides information to a train for each distance from a route or starting point will be described. Here, railway operators provide tourist guides on the nearest station to the current train location for trains traveling at various locations on various routes. FIG. 47 is a diagram showing an overview of the method for providing a tourist guide for the train. The railway company provides a tourist guide to the trains (4715, 4720, 4725) via the HEO satellite 4710 from the distribution station 4705 for providing the tourist guide. At this time, the train (4715, 4720, 4725) acquires the distance from the starting point by a device (hereinafter referred to as a transponder) (4730, 4735, 4740) that provides the distance from the starting point. Then, using the acquired distance information and the route information possessed by the train, a tourist guide necessary for the train is selected.

  Train 4715 and train 4720 are running on the Joban Line, train 4715 is at a point 100 km from Ueno Station, which is the starting point, and train 4720 is at a point 150 km from Ueno Station, which is the starting point. Train 4740 is running on the Chuo Line and is 120 km from Tokyo Station, the starting point.

Here, a process in which the distribution station 4705 distributes the tourist guide will be described. The distribution station 4705 includes a content group in which the tourism guide is accumulated, route information that is information for limiting the target for providing the content group, route information for providing distance information from the starting point, and distance information from the starting point. The route information corresponding to each content and the distance information from the starting point are added and distributed. The content (tourist guide) to which the distributed route information and the distance information from the starting point are added is distributed to the trains (4715, 4720, 4725) via the HEO satellite 4710. Trains (4715, 4720, 4725) store in advance information on routes on which the vehicle is running. Furthermore, the train (4715, 4720, 4725) acquires distance information from the starting point from the transponder (4730, 4735, 4740). The train (4715, 4720, 4725) compares the route information added to the delivered content with the route information stored in the train, and further, the distance information from the starting point added to the content, and the transponder (4730, 4730, 4725). 4735, 4740), the distance information from the starting point, and the information selected on the monitor or the electronic bulletin board for displaying the tourist guide in the train by selecting only the contents that match the information. Is displayed.

For example, consider the case where a train 4715 running on the Joban Line 100km from Ueno receives a tourist guide. 48 to 50 show contents (4800, 4900, 5000) distributed by the distribution station 4705, respectively, from the contents 4800 for trains traveling on the Joban line 100km from Ueno (starting point) and Ueno (starting point). The content 4900 for trains traveling on the Joban line at 150 km and the content 5000 for trains traveling on the central line 120 km from Tokyo (starting point). The content 4800 describes route information 4810 “Joban Line”, distance information 4820 from the starting point “100 km from Ueno”, and tour guide content 4830 “Mito Festival, Mito Park; 2 minutes walk from Mito Station”. Yes. Content 4900 describes route information 4910 “Joban Line”, distance information 4920 “150 km from Ueno” and tour guide content 4930 “Iwaki Fireworks Festival August 15 Iwaki Park: 5 minutes walk from Iwaki Station” Has been. Content 5000 includes route information 5010 “Chuo Line”, distance information 4920 “120 km from Tokyo”, and tour guide content 5030 “Grape Festival being held Grape Park: 5 minutes on foot from Kofu Station”. .

Train 4715 is distance information from the starting point from transponder 4730 “100 from Ueno”
The distance information “100 km from Ueno” is compared with the distance information from the starting point added to the content to be distributed, and the route information “Joban Line” stored in the train 4715 is also stored. And the route information added to the content to be distributed, and selects the content 4800 in which both match, and the tour guide content 4830 of the selected content 4800 “Mito Festival during the Mito Festival is held; "2 minutes on foot" is displayed on the train monitor or on the electric bulletin board.

  Next, consider a case where a train 4725 running on the Chuo Line 120km from Tokyo receives a tourist guide.

Train 4725 is distance information from the starting point from the transponder 4740 “120 from Tokyo.
km ”, and the distance information“ 100 km from Tokyo ”is compared with the distance information from the starting point added to the content to be distributed, and further, the route information“ Chuo Line ”stored in the train 4725 is stored. And the route information added to the content to be distributed, and selects the content 5000 that matches the two.The tourist guide content 5030 “Grape Festival being held for the selected content 5000 Grapes Park: walk to Kofu Station "5 minutes" is displayed on the train monitor or on the electric bulletin board.

  By carrying out like this, optimal information can be provided for every train with respect to several trains which run on a different route and a different place.
