  In the above conventional system, an advertisement or the like is distributed to all the vehicles in the distribution area, and it is determined whether or not the advertisement is displayed on the vehicle side. Therefore, when an advertisement is distributed to a vehicle that cannot safely see the advertisement (for example, a vehicle that cannot stop due to a red light), the distributed advertisement is not displayed on the vehicle. Therefore, the distributed advertisement is wasted and unnecessary distribution has been performed. The advertising cost is also wasted on the facility that issued the advertisement.

  Then, this invention makes it a subject to provide the advertisement distribution system for vehicles which distributes an advertisement effectively to a vehicle.

  The vehicle advertisement distribution system according to the present invention is a vehicle advertisement distribution system that distributes an advertisement from a roadside device to a vehicle, and includes a stopped vehicle prediction unit that predicts a vehicle that stops at a red signal based on signal cycle information. The roadside device is characterized in that the advertisement is distributed only to the vehicle predicted to stop by the stopped vehicle prediction means.

  In this vehicle advertisement distribution system, whether or not the vehicle stops at a red signal based on the signal cycle information of the traffic light by the stop vehicle prediction means (that is, whether or not an advertisement can be safely viewed in the vehicle). Predict. In the vehicle advertisement distribution system, the advertisement is distributed from the roadside device only to the vehicle that is predicted to stop at a red light. Thus, the vehicle can provide the advertisement to the driver when the vehicle stops at a red light, and the driver can view the advertisement while waiting for the signal. In this way, in this vehicle advertisement distribution system, the advertisement becomes effective by distributing the advertisement only to the vehicle predicted to stop at a red light (the distributed advertisement can be seen by the driver) Advertisements can be effectively distributed to vehicles. For the driver, the advertisement can be confirmed in a safe state waiting for the signal. For advertisers, advertising costs are not wasted and advertising effectiveness is great. The advertisement to be distributed includes the latest information of the facility in addition to the basic information for informing the facility.

  In the roadside apparatus of the vehicle advertisement distribution system according to the present invention, it is preferable that the advertisement for the facility is distributed only to a vehicle traveling on the traveling lane on which the facility is arranged.

  It is considered that there is a possibility (driver's will) to stop by the vehicle in the driving lane on the side where the facility is located, compared to vehicles in other driving lanes, so it is possible to deliver advertisements more efficiently and to the driver It becomes a very effective advertisement. On the other hand, since it is considered that there is a low possibility that a vehicle in a driving lane where the facility is not located will stop at the facility, unnecessary advertisements can be prevented from being delivered, and unnecessary advertisements can be presented to the driver. Further, since the advertisement is not provided to the driver of the vehicle in the traveling lane where the facility is not arranged, it is possible to prevent a sudden lane crossing to go to the facility of the advertisement.

  The present invention can effectively distribute advertisements to vehicles by distributing advertisements only to vehicles that stop at a red light.

  Hereinafter, an embodiment of a vehicle advertisement distribution system according to the present invention will be described with reference to the drawings.

  In the present embodiment, the vehicle advertisement distribution system according to the present invention is applied to an infrastructure-linked advertisement / latest information distribution system using a road-to-vehicle communication system using optical beacons. The infrastructure-linked advertisement / latest information distribution system according to the present embodiment is configured by an optical beacon as a roadside device and an in-vehicle communication device mounted on each vehicle, and between the optical beacon and each in-vehicle communication device. Can send and receive information. In particular, in the infrastructure-linked advertisement / latest information distribution system according to the present embodiment, advertisements and latest information of various facilities are distributed from the optical beacon to each in-vehicle communication device, and the information is provided to the driver on the vehicle side.

  With reference to FIGS. 1-3, the infrastructure cooperation advertisement and the newest information delivery system 1 which concern on this Embodiment are demonstrated. FIG. 1 is a conceptual diagram of an infrastructure-linked advertisement / latest information distribution system according to the present embodiment. FIG. 2 is a configuration diagram of the infrastructure-linked advertisement / latest information distribution system according to the present embodiment. FIG. 3 is an example of the vicinity of an intersection in which the infrastructure-linked advertisement / latest information distribution system according to the present embodiment is configured.

  The infrastructure-linked advertisement / latest information distribution system 1 includes an optical beacon 10 installed on the roadside and an in-vehicle communication device 20 mounted on each vehicle. The optical beacon 10 is installed at a position a predetermined distance from the intersection C on a general road. In the infrastructure-linked advertisement / latest information distribution system 1, data can be transmitted and received between the optical beacon 10 and the in-vehicle communication device 20 using near infrared rays. In the infrastructure-linked advertisement / latest information distribution system 1, VICS [Vehicle Information Communication System] information and infrastructure cooperation information are usually downlinked from the optical beacon 10 to the in-vehicle communication device 20, and the vehicle information is transferred from the in-vehicle communication device 20 to the optical beacon 10. Uplink.

  VICS information is road traffic information common to all lanes. Road traffic information includes traffic jam information, traffic regulation information, and parking lot information. The infrastructure coordination information includes signal cycle information for each lane, road alignment information common to all lanes, stop line information, speed limit information, and the like. The signal cycle information includes a lighting time of each of a blue signal, a yellow signal, and a red signal, a lighting time of a right turn instruction signal, a currently lit signal, and an elapsed time after the signal is lit. From this signal cycle information, for example, it can be determined how many seconds later the red signal is generated, and in the case of a right turn lane, how many seconds it takes to give a right turn instruction, and how many seconds later. The vehicle information to be uplinked includes a vehicle ID for identifying the vehicle, a vehicle speed, and the like.

  In particular, as shown in FIG. 1, in the infrastructure-linked advertisement / latest information distribution system 1, the driver needs, the driver state, and the vehicle state are also included in the in-vehicle communication device so that only the facility information required on the vehicle side is distributed. Uplink from 20 to optical beacon 10. Driver needs include unspecified destinations according to drivers and passengers, such as parking lots, dining facilities, convenience stores, and gas stations. In the optical beacon 10, a facility is selected according to the driver needs. The driver state includes, for example, an arousal level and a fatigue level. In the optical beacon 10, when the driver needs to rest from this driver state, a facility that can cope with the rest is selected. Examples of the vehicle state include a gasoline remaining amount, a tire remaining groove, a battery charge amount, and a vehicle inspection residue. The optical beacon 10 selects a facility that can handle refueling or maintenance of the vehicle from this vehicle state.

  The infrastructure-linked advertisement / latest information distribution system 1 predicts a vehicle that stops at a red signal in the optical beacon 10 in order to distribute only to vehicles that can safely see advertisements of facilities, and the predicted vehicle When the vehicle is approaching near the facility, only the vehicle traveling in the traveling lane on which the facility is arranged is selected, and when the vehicle is not approaching near the facility, the vehicles of all the traveling vehicles are selected. In the infrastructure-linked advertisement / latest information distribution system 1, the facility information corresponding to the needs on the vehicle side is downlinked from the optical beacon 10 to the in-vehicle communication device 20 only for the selected vehicle.

  As shown in FIG. 3, the distributed facility is a facility that can be reached from a road that goes straight or turns right or left at an intersection C in front of the road on which the vehicles V1, V2,. This facility is not limited to facilities F1... Along the straight road and facilities F3, F4... Facilities F2 ... are also included. These facilities F2... That are not along the running road are less likely to be directly confirmed by the driver's eyes, and therefore have a higher effect of advertising than the facilities F1, F3. .

  Facility information includes facility advertisements and the latest information. The advertisement is basic information of the facility, and includes business type, business hours, regular holidays, fee information, position information (latitude and longitude), and the like. The latest information is information updated daily at the facility, and includes charge information, service information, and the like.

  Further, in the infrastructure-linked advertisement / latest information distribution system 1, in order to provide the driver with facility information according to the needs on the vehicle side, the distributed facility information is displayed on a navigation screen or the like, and the driver's request is received. In response, route guidance to the facility is also provided.

  The downlink area of the optical beacon 10 is set before K (m) of the optical beacon 10, the lane traveling direction is in the range of the area size L (m), and the lane width direction is in the range of about the lane width. . The uplink area of the in-vehicle communication device 20 is set in front of the optical beacon 10, and the lane traveling direction is in a range of M (m). The uplink area has the same position as the downlink area and the entrance edge, and is narrower than the downlink area (L> M). Therefore, after uplinking with each vehicle V1 ..., it is possible to downlink with respect to the uplinked vehicle V1 .... These K (m), L (m), and M (m) are values preset in the standard.

  With reference to FIG.2 and FIG.3, the optical beacon 10 is demonstrated. In the optical beacon 10, various information is uplinked from each vehicle traveling in the uplink area, and VICS information and infrastructure cooperation information are downlinked in the downlink area for all vehicles. In particular, the optical beacon 10 searches for a vehicle in which an advertisement can be safely viewed, and downlinks facility information (advertisement and latest information) according to the needs on the vehicle side only to the searched vehicle. For this purpose, the optical beacon 10 includes a communication device 11, optical beacon heads 12 for each lane, and a control device 13. In the present embodiment, the processing in the control device 13 corresponds to the stopped vehicle prediction means described in the claims.

  The communication device 11 is a device that transmits and receives various types of information, and includes an antenna, a transmission unit, and a reception unit. The antenna is a transmission / reception antenna that transmits and receives various signals. The antenna is an omnidirectional antenna, and receives signals from all directions and transmits signals in all directions. When transmitting, various information is modulated by the transmission unit, and the transmission signal is transmitted from the antenna. When receiving, the received signal is received by the antenna, and the received signal is demodulated by the receiving unit to extract various information.

  The communication device 11 receives signal cycle information from the controller of the traffic light S at the intersection C ahead. In addition, the communication device 11 receives VICS information from the VICS center. Further, the communication device 11 receives advertisements, latest information, and the like from the surrounding facilities F1... Using the Internet or the like.

  The optical beacon head 12 is a head provided for each lane and capable of transmitting and receiving near infrared rays. The optical beacon head 12 is disposed above the center line of the lane, and is installed toward the diagonally rear side on the lower side. The optical beacon head 12 receives a signal from within the uplink area, demodulates the signal, and outputs various information extracted to the control device 13. In addition, the optical beacon head 12 modulates the VICS information and the infrastructure cooperation information from the control device 13 in response to a command from the control device 13 for all vehicles, and sends the modulated transmission signal to the downlink area. Downlink. Further, the optical beacon head 12 modulates facility information from the control device 13 only for the vehicle selected by the control device 13 in accordance with a command from the control device 13, and transmits the modulated transmission signal to the downlink area. Downlink in. Note that the facility information is downlinked to the vehicle selected by the control device 13 by downlinking the facility information into the downlink area at the timing instructed by the control device 13.

  The control device 13 is an electronic control unit including a CPU [Central Processing Unit], a ROM [Read Only Memory], a RAM [Random Access Memory], and the like, and comprehensively controls the optical beacon 10. A database 13a for storing facility information is constructed in a predetermined area of the RAM of the control device 13.

  The control device 13 acquires the VICS information edited and processed at the VICS center via the communication device 11 at regular time intervals. Moreover, in the control apparatus 13, signal cycle information is acquired from the controller of the front traffic light S via the communication apparatus 11 for every fixed time, the road linear information around the optical beacon 10 currently hold | maintained, a stop line Infrastructure cooperation information is generated from information, speed limit information, etc. and signal cycle information thereof. Further, the control device 13 acquires various types of information from the surrounding facilities F1... Via the communication device 11. Further, the control device 13 acquires various types of information on the uplinked vehicle via the optical beacon head 12. The information on the surrounding facilities F1... May be acquired by another means without going through the communication device 11. For example, the information is acquired directly from each facility and input to the control device 13 in advance.

  When the control device 13 acquires information on each of the surrounding facilities F1..., All the facilities F1... Are classified by industry, and the facilities for each industry are branched from the intersection C by road (straight road, right turn). (Destination road, left turn destination road). Further, the control device 13 determines the priority order for distribution for each road of each industry. As a method for determining the priority, for example, the order in which the advertising costs are bid from each facility F1,..., The order from the highest customer evaluation, the order from the lowest price (gasoline, parking fee, etc.), the order from the intersection C. To determine the priority. And in the control apparatus 13, the information of the facility arranged in order of priority for every road of each industry is stored in the database 13a. Further, each time information such as the latest information is input from each facility F1..., The control device 13 rewrites the information stored in the database 13a.

  By the way, the advertising costs may be decided by the facility by bidding, etc., or the distance from the intersection C, whether it is along the road intersecting at the intersection C, the number of driving lanes, the probability that the vehicle will travel, etc. You may decide by. For example, the closer the facility is from the intersection C, the more difficult it is for vehicles traveling in the right lane to enter the facility. In the case of a facility that is not along the road, the driver usually has a high possibility of not being able to confirm directly with the eyes, and since the driver is not informed unless an advertisement is issued, the advertising cost is higher than the facility along the road. When the number of driving lanes on the road is one lane, all traveling vehicles are easy to enter the facility, so the advertising costs are higher than in the case of multiple lanes. When the probability of traveling on the facility side is low such that the vehicle can turn right or go straight, or turn left or go straight (for example, the probability that the vehicle will come to the facility side becomes 50%), always turn left, turn right, go straight Thus, the advertising cost is made lower than when the probability of traveling on the facility side is high (when the probability that the vehicle is on the facility side is 100%).

  At certain time intervals, the control device 13 transmits VICS information common to all lanes and infrastructure cooperation information for each lane to each optical beacon head 12..., And each optical beacon head so as to downlink each information. 12 is command-controlled.

  Each time various information of the uplinked vehicle is input (that is, every time the vehicle passes through the uplink area of the optical beacon 10), the control device 13 increases the vehicle speed (uplink information) and the vehicle. Based on the distance (specified value) from the entrance edge of the link area to the intersection C, the time required for the vehicle to reach the intersection C is calculated. Then, the control device 13 predicts and determines whether or not the vehicle stops at the red signal of the traffic light S based on the calculated time and the signal cycle information of the traffic light S. If it is determined that the vehicle will not stop at the red light, the control device 13 ends the facility information distribution process for the vehicle.

  If it is predicted to stop at a red light, the control device 13 determines the facility required on the vehicle side according to the needs information (driver needs, driver status, vehicle status) on the vehicle side uplinked from the vehicle. Determine the industry. Further, the control device 13 determines a road on which the vehicle may travel after passing the intersection C based on the lane in which the vehicle is currently traveling. For example, in the case of a one-lane road, the vehicle may travel on a road that goes straight through intersection C, a right-turn road, or a left-turn road. In the case of a one-lane two-lane road, a vehicle traveling in the left lane may travel straight on the intersection C or a road on the left turn, and a vehicle traveling in the right lane may travel straight on the intersection C or There is a possibility of driving on the road to the right. In the case of a three-lane road on one side, a vehicle traveling in the left lane may travel on a road that goes straight on the intersection C or a road on the left turn, and a vehicle traveling on the central lane may travel on a road that travels straight on the intersection C. There is a possibility that the vehicle traveling and traveling in the right lane may travel on the road straight ahead at the intersection C or on the road to the right turn. Then, the control device 13 refers to the database 13a and selects a facility with a high priority according to the determined business type and the road after passing through the intersection C. Here, when there are a plurality of roads that may travel after passing through the intersection C, a facility is selected for each road. Further, for each road, only one facility with the highest priority may be selected, or a plurality of facilities may be selected in order of priority.

  In addition, when the needs information on the vehicle side is not uplinked from the vehicle, when the facility of the industry according to the needs on the vehicle side is not in the database 13a, or the needs information is uplinked from the vehicle, the vehicle side If there is no business type that is required, the facility information may not be distributed, or the facility information may be distributed. In the case of distribution, for example, a facility with a high advertising cost, a facility useful for the driver (for example, a facility with service information, a facility with a low charge), or the like is selected.

  When a facility is selected, the control device 13 determines, for each selected facility, whether or not the facility is more than a threshold distance from the intersection C based on the position information of the facility and the position of the intersection C. The threshold distance is a distance indicating whether or not the vehicle can safely change lanes, and is set in advance by an experiment at each intersection C or the like. In other words, when the vehicle stops at a red light, the driver looks at the advertisement and determines whether the lane can be safely changed to enter the facility so that it does not suddenly cross the lane to enter the facility. To do.

  When it is determined that the distance is less than the threshold distance, the control device 13 determines whether or not the vehicle is in the lane on the side where the facility is arranged, and determines that the facility information is distributed for vehicles in the lane on the side where the facility is arranged. It is determined that the facility information is not distributed for vehicles in the lane where the facility is not located. The lane on the side where the facility is located is the leftmost lane or the leftmost lane in the straight-line lane when the facility is in the vicinity of the road that goes straight through the intersection C. Around the road where the facility turns right at the intersection C If the facility is in the vicinity of the road ahead of the intersection C at the left, it is the left-end lane or the left-turn lane. That is, information on the facility is distributed only to vehicles in the lane that can safely go to the facility after passing through the intersection C.

  If it is determined that the distance is greater than or equal to the threshold distance, the control device 13 determines to distribute the facility information to the vehicle. That is, since it is possible to safely go to the facility from any lane, information on the facility is distributed regardless of the lane in which the vehicle is traveling. Naturally, the vehicle in the right lane should not turn left, the vehicle in the left lane should not turn right, the vehicle in the right lane should be other than right, the vehicle in the left lane should be other than left, and the vehicle in the straight lane should be other than straight It is a premise to not.

  Then, the control device 13 transmits the facility information determined to be distributed to the optical beacon head 12 on the lane that can be traveled by the vehicle to be distributed, and controls the optical beacon head 12 to downlink the facility information. . When there is no facility information to be distributed, the control device 13 does not perform this command control. Here, facility information to be distributed after the information is uplinked from the vehicle is quickly determined, and the facility information is distributed before the vehicle exits the downlink area.

  In the case of the example shown in FIG. 3, since the vehicle V1 and the vehicle V3 are predicted not to stop at a red signal (that is, to pass through the intersection C with a green signal), the facility information is not distributed. The vehicle V2 is predicted to stop at a red light. Since the vehicle V2 is traveling in the left lane and may go straight or turn left, the facility F1, the facility F2, and the facility F4 are selected according to the needs on the vehicle V2 side. The facility F1 is close to the intersection C and less than the threshold distance, but the information on the facility F1 is distributed because the vehicle V2 is the left lane. Since the facility F2 is more than the threshold distance from the intersection C, the information on the facility F2 is distributed. The facility F4 is close to the intersection C and less than the threshold distance, but the information on the facility F4 is distributed because the vehicle V2 is the left lane. Therefore, each information of the facility F1, the facility F2, and the facility F4 is distributed to the vehicle V2. The vehicle V4 is predicted to stop at a red light. Since the vehicle V4 is traveling in the right lane and may go straight or turn right, the facility F1, the facility F2, and the facility F3 are selected according to the needs on the vehicle V4 side. Since the facility F1 is close to the intersection C and less than the threshold distance, and the vehicle V4 is the right lane, information on the facility F1 is not distributed. Since the facility F2 is more than the threshold distance from the intersection C, the information on the facility F2 is distributed. The facility F3 is close to the intersection C and less than the threshold distance, but the information on the facility F3 is distributed because the vehicle V4 is the right lane. Therefore, each information of the facility F2 and the facility F3 is distributed to the vehicle V4.

  With reference to FIG.2 and FIG.3, the vehicle-mounted communication apparatus 20 is demonstrated. The in-vehicle communication device 20 uplinks various information when entering the uplink area. Further, when entering the downlink area, the in-vehicle communication device 20 provides the VICS information to the navigation device and the infrastructure cooperation information to the driving support device when the VICS information and the infrastructure cooperation information are downlinked. In particular, when the facility information is downlinked in the downlink area, the in-vehicle communication device 20 provides the facility information to the navigation system 26 after confirming the stop of the vehicle. For this purpose, the in-vehicle communication device 20 includes an optical beacon antenna 21, an optical beacon transceiver 22, a driver input device 23, a driver state detection device 24, a vehicle state detection device 25, and an ECU [Electronic Control Unit] 29, and navigation. System 26 is used.

  The optical beacon antenna 21 and the optical beacon transceiver 22 are equipment for transmitting and receiving data to and from the optical beacon 10 using near infrared rays. The optical beacon antenna 21 is disposed at a predetermined position of the vehicle and is installed obliquely forward on the upper side. The optical beacon antenna 21 receives a signal from the optical beacon head 12 in the downlink area and transmits a signal in the uplink area. In the case of downlink, the optical beacon transceiver 22 demodulates the signal received by the optical beacon antenna 21, extracts various information, and transmits the various information to the ECU 29. In addition, in the case of uplink, the optical beacon transceiver 22 modulates various information input from the ECU 29 in response to a command from the ECU 29 and transmits the modulated signal to the optical beacon antenna 21.

  The driver input device 23 is a device for inputting the needs of the driver (or passengers) and necessity / unnecessity of route guidance, and any input means may be used. For example, it is assumed that the input device uses a selection format from each item displayed on the display 27. The driver input device 23 transmits the input information to the ECU 29 when the needs from the driver and the need for route guidance are input. Note that the driver input device 23 may use the information input function of the navigation system 26.

  The driver state detection device 24 is a device that detects the state of the driver (wakefulness, fatigue level, etc.), and any detection means may be used. When the driver state detection device 24 detects the state of the driver, the driver state detection device 24 transmits the detected information to the ECU 29.

  The vehicle state detection device 25 is a variety of devices that detect the vehicle state (vehicle speed, gasoline remaining amount, tire remaining groove, battery charge amount, etc.), and any detection means may be used. When the vehicle state detection device 25 detects the state of the vehicle, the detected information is transmitted to the ECU 29.

  The navigation system 26 is a system that detects the current position of the host vehicle and provides route guidance to the destination. In particular, in the navigation system 26, when facility information is received from the ECU 29, image information for superimposing and displaying the facility's advertisement and the latest information on the corresponding position on the map of the navigation screen based on the location information of the facility. And the image information is transmitted to the display 27. Further, when the navigation system 26 receives a route guidance instruction from the ECU 29 to the facility, the navigation system 26 calculates the route to the facility, sequentially generates image information and audio information for guiding the route, and converts the image information into The audio information is transmitted to the speaker 28 while being transmitted to the display 27.

  The ECU 29 is an electronic control unit that includes a CPU, a ROM, a RAM, and the like, and performs overall control of the in-vehicle communication device 20. The ECU 29 receives each piece of information from the driver input device 23, the driver state detection device 24, and the vehicle state detection device 25, and receives each piece of information downlinked from the optical beacon transceiver 22.

  The ECU 29 acquires the driver needs from the driver input device 23 (there may be no need) every time it is input from the driver, and also the driver state and vehicle state detection device from the driver state detection device 24 at regular intervals. The vehicle state from 25 is acquired. When entering the uplink area, the ECU 29 transmits the driver's needs, driver status, vehicle status, vehicle ID, and the like to the optical beacon transmitter / receiver 22, and sets the optical beacon transmitter / receiver 22 to uplink each information. Command control.

  When the ECU 29 acquires the VICS information and the infrastructure cooperation information from the optical beacon transceiver 22, the ECU 29 transmits the VICS information to the navigation system 26 and transmits the infrastructure cooperation information to the driver support device.

  In ECU29, if facility information is acquired from the optical beacon transceiver 22, it will be determined whether the vehicle stopped based on the vehicle speed. When it is determined that the vehicle has stopped, the ECU 29 transmits facility information (advertisement, latest information) to the navigation system 26. In addition, in the case where the ECU 29 has acquired information indicating that route guidance is required from the driver input device 23, the ECU 29 also transmits a route guidance command to the navigation system 26. The vehicle stop determination may be performed by the navigation system 26. In this case, when the ECU 29 acquires the facility information from the optical beacon transceiver 22, the facility information is immediately transmitted regardless of the stop of the vehicle. 26. At this time, if the navigation system 26 determines that the vehicle has stopped, the facility information is displayed on the navigation screen.

  With reference to FIG.2 and FIG.3, the operation | movement in the infrastructure cooperation advertisement and the newest information delivery system 1 is demonstrated. Here, only operations related to facility information will be described. In the database 13a of the control device 13, it is assumed that facility information including advertisements of the facilities F1... And the latest information is stored for each road of each industry.

  When the needs from the driver are input, the driver input device 23 of each vehicle transmits the information to the ECU 29. Further, the driver state detection device 24 detects the state of the driver at regular time intervals and transmits the driver state to the ECU 29. In addition, the vehicle state detection device 25 detects each state of the vehicle at regular intervals and transmits the vehicle state to the ECU 29. The ECU 29 receives each piece of information.

  When the vehicle enters the uplink area, the ECU 29 transmits a driver need, a driver state, a vehicle state, a vehicle ID, and the like to the optical beacon transmitter / receiver 22 and performs command control to uplink each information. In response to this command, the optical beacon transceiver 22 modulates each information and uplinks the modulated signal from the optical beacon antenna 21.

  The optical beacon head 12 of the optical beacon 10 receives the uplink modulated signal, demodulates the modulated signal, extracts each piece of information, and transmits it to the control device 13.

  When the uplinked information is received, the control device 13 calculates the time required for the vehicle to reach the intersection C based on the vehicle speed of the uplinked vehicle and the distance to the intersection C. Then, the control device 13 determines whether or not the vehicle stops at the red signal of the traffic light S based on the calculated time and the signal cycle information of the traffic light S. If it is predicted that the vehicle will not stop due to a red light, the facility information is not distributed because the vehicle cannot safely see the advertisement of the facility.

  When it is predicted that the vehicle will stop at a red light, the control device 13 determines the type of business of the facility in accordance with the needs information on the uplinked vehicle side, and travels after passing through the intersection C based on the traveling lane of the vehicle. Determine the roads that are likely to do. Then, the control device 13 refers to the database 13a, selects a facility with high priority according to the determined business type and road, and extracts information on the facility from the database 13a. If there is no facility that can be selected, the facility information is not distributed.

  When the facility information is extracted from the database 13a, the control device 13 determines, for each extracted facility, whether the facility is separated from the intersection C by a threshold distance or more based on the location information of the facility. When it is determined that the distance is less than the threshold distance, the control device 13 determines whether the vehicle is traveling in the lane on the side where the facility is arranged. When it is determined that the vehicle is traveling in the lane on the side where the facility is arranged, there is a possibility of entering the facility and the facility can be safely entered. Decide to deliver. On the other hand, if it is determined that the vehicle is not traveling in the lane on which the facility is located, the possibility of entering the facility is low and the facility cannot be safely entered. It is decided not to deliver the information. On the other hand, if it is determined that the distance is greater than or equal to the threshold distance, any lane can safely enter the facility, and the control device 13 determines to distribute the facility information to the vehicle.

  And in the control apparatus 13, the information of the facility determined to deliver is transmitted to the optical beacon head 12 of the lane of the vehicle to deliver, and the optical beacon head 12 is commanded to downlink the information on the facility. In response to this command, the optical beacon head 12 modulates the facility information and transmits the modulated signal to the downlink area. At this time, the uplinked vehicle is still traveling in the downric area.

  In a vehicle traveling in the downlink area, the optical beacon antenna 21 receives the modulation signal, the optical beacon transceiver 22 demodulates the modulation signal, extracts facility information, and transmits the facility information to the ECU 29. .

  When this facility information is received, the ECU 29 determines whether or not the vehicle has stopped based on the vehicle speed. When it is determined that the vehicle has stopped, the ECU 29 transmits facility information to the navigation system 26. When the facility information is received, the navigation system 26 generates image information for displaying the facility information on the map of the navigation screen, and transmits the image information to the display 27. When this image information is received, the display 27 displays a navigation screen corresponding to the image information.

  At this time, since the vehicle is stopped at a red light, the driver views advertisements and latest information of each facility on the navigation screen in a safe state. Each of the displayed facilities is a facility that meets the needs of the vehicle and can be safely accessed from the lane in which the vehicle is currently located. Therefore, when the driver wants to go to the facility after seeing the advertisement and the latest information and performs a driving operation aiming at the facility on the navigation screen, the vehicle can safely go to the facility. At this time, when the driver requests route guidance from the driver input device 23, the navigation system 26 provides route guidance to the facility.

  According to this infrastructure-linked advertisement / latest information distribution system 1, by distributing facility information only to vehicles that are predicted to stop at a red light, the driver can be sure that the facility information is viewed. The distributed facility information becomes effective, and the facility information can be effectively distributed to the vehicle. The driver can check the advertisement of the facility in a safe state waiting for the signal. For the facility side, the advertising cost is not wasted and the advertising effect is great.

  According to the infrastructure-linked advertisement / latest information distribution system 1, the advertisement can be distributed more efficiently by distributing the facility information only to the vehicle in the lane on the side where the facility is located immediately before the facility. For the driver, information on facilities that are difficult to go to is not distributed, so unnecessary information on facilities is displayed less. In addition, it is possible to prevent a sudden lane crossing to go to the facility, and traffic flow is not obstructed.

  According to the infrastructure-linked advertisement / latest information distribution system 1, only facility information required on the vehicle side is obtained by distributing facility information according to vehicle needs such as driver needs, driver status, and vehicle status. It is distributed and can be distributed more efficiently. For the driver, there is no need to see troublesome facility information that is not necessary on the vehicle side. There is no waste of advertising costs for the facility.

  As mentioned above, although embodiment which concerns on this invention was described, this invention is implemented in various forms, without being limited to the said embodiment.

  For example, in this embodiment, the present invention is applied to an infrastructure-linked advertisement / latest information distribution system as one function of a road-to-vehicle communication system using an optical beacon. However, as a roadside device, a road-to-vehicle communication system other than an optical beacon is used. Alternatively, other device configurations such as incorporating a vehicle-side device into a navigation system or the like may be adopted.

  In this embodiment, the navigation system is used to display information such as advertisements and route guidance to the facility. However, in the case of a vehicle not equipped with the navigation system, the ECU of the in-vehicle communication device You may make it transmit a display control signal to a display, and an audio | voice control signal directly to a speaker.

  Further, in the present embodiment, it is configured to predict whether or not the vehicle stops at the red beacon side on the optical beacon side, but whether or not to stop at the red signal in the vehicle monitoring device or the like deployed on the vehicle side or the road side. The prediction information may be transmitted to the optical beacon side.

  Further, in the present embodiment, the driver needs are uplinked to the optical beacon from the vehicle side and the facility information corresponding to the needs on the vehicle side is distributed. However, the driver side is not uplinked, and the vehicle side The facility information may be distributed regardless of the needs. In this case, a driver input device, a driver state detection device, and a vehicle state detection device are not necessary.

  Also, in this embodiment, it is determined whether or not it is immediately before the location of the facility, and in the case of immediately before, it is configured to distribute only to vehicles on the driving lane on the facility side, but it is determined whether or not it is immediately before the location of the facility Instead, it may be distributed to all vehicles predicted to stop at a red light.
