  Hereinafter, the operation of the traffic information processing system 1 according to the present embodiment will be specifically described with reference to FIGS.

  Referring to FIG. 6, when a passenger (driver or passenger) of vehicle 3A confirms an event that may cause some traffic event, the passenger uses provision intention information S11 indicating an intention to provide information. Input from the input unit 58. For example, in the event of witnessing an event that may cause traffic congestion, such as an increase in traffic volume, a traffic accident, a marching of a demonstration team, or a local heavy rain, the intention to provide S11 Is input from the input unit 58. The providing intention information S11 can be input by, for example, pressing a button such as a steering switch provided in the vehicle 3A or operating a panel such as a touch panel of a car navigation system.

  Here, the acquisition unit 51 operates based on detection signals from a wheel speed sensor, a GPS (Global Positioning System) receiver, a gyro sensor, and an inter-vehicle distance sensor mounted on the vehicle 3A. Status information S31 is acquired. The driving status information S31 is input from the acquisition unit 51 to the control unit 55. Based on the driving status information S31, the control unit 55 determines whether the vehicle 3A is making a right turn or a left turn, the vehicle 3A is traveling at a certain speed or more, the vehicle 3A is traveling within an intersection, and the vehicle In a dangerous situation when the driver's attention of the vehicle 3A becomes distracted, such as the distance between the vehicle 3A and the preceding and following vehicles is within a certain value, the input of the provision intention information S11 from the input unit 58 is not accepted. You may control to. In this case, an acceptance rejection voice message or buzzer sound is output from the speaker 56, or an acceptance rejection text message or image is displayed on the car navigation screen. This makes it possible to ensure the safety of driving the vehicle 3A.

  When the control unit 55 receives the input of the provision intention information S11, the provision intention information S11 is wirelessly transmitted from the transmission unit 54 to the traffic information processing apparatus 2.

  Referring to FIG. 4, acquisition unit 31 receives provision intention information S <b> 11 from in-vehicle device 4 </ b> A and inputs received provision intention information S <b> 11 to estimation unit 32.

  The estimation means 32 estimates that an event that may cause some traffic event occurs in the vicinity of the current location of the vehicle 3A when the provision intention information S11 transmitted from the in-vehicle device 4A is input. Then, the estimation result information S12 including the identification information of the in-vehicle device 4A and the current location information of the vehicle 3A is input to the specifying unit 33. The estimation means 32 collects probe information sent from a plurality of vehicles and vehicle detection information sent from a vehicle detector installed on the road, and traffic conditions based on the collected information. By analyzing the above, whether or not a traffic event such as a traffic jam occurs at a certain point or area is constantly monitored.

  Based on the estimation result information S12, the specifying unit 33 specifies an in-vehicle device to which question information S14 described later is to be transmitted. In this example, the specifying unit 33 specifies the in-vehicle device 4A that has transmitted the provision intention information S11 as the in-vehicle device to which the question information S14 is to be transmitted. The identification unit 33 inputs the identification result information S13 to the transmission unit 34.

  Here, the specifying unit 33 is not only mounted on the vehicle-mounted device 4A as the vehicle-mounted device to which the question information S14 is to be transmitted, but also mounted on another vehicle located around the vehicle 3A (for example, mounted on the vehicle 3B). The mounted on-vehicle device 4B) may be specified.

  The question information S14 for inquiring the user about the occurrence of a traffic event is created in advance and stored in the storage means 35. For example, voice information relating to questions such as “Is there a traffic jam around you?” And “Is there anything likely to cause a traffic jam?” Is prepared as the question information S14. The transmission unit 34 transmits the question information S14 read from the storage unit 35 to the in-vehicle device 4A identified as the transmission target by the identification result information S13. When a plurality of transmission targets of the question information S14 are specified by the specifying unit 33, the question information S14 is transmitted to each of the plurality of in-vehicle devices.

  Here, even if the traffic information processing device 2 receives the provision intention information S11 from the in-vehicle device 4A, the estimation means 32 is not able to perform any traffic based on the current location of the vehicle 3A, the probe information, the vehicle sensing information, and the like. If the point or area where the occurrence of the event is estimated does not overlap, the question information S14 may not be transmitted from the transmission unit 34. As a result, the traffic information processing device 2 does not respond to the user's erroneous operation or transmission of the provision intention information S11 for the purpose of mischief, whereby the processing load on the traffic information processing device 2 can be reduced. On the other hand, even if the current location of the vehicle 3A and the point or area where the estimation means 32 estimates the occurrence of some traffic event based on the probe information, vehicle sensing information, etc., do not overlap The question information S14 may be transmitted from the means 34. As a result, it may be possible to quickly detect the occurrence of a traffic event that has not yet been detected depending on probe information or the like.

  Referring to FIG. 6, receiving unit 53 receives question information S14 from traffic information processing apparatus 2 and inputs received question information S14 to control unit 55. The control unit 55 outputs the question information S14 by voice from a speaker 56 (also usable as a car navigation speaker) provided at an arbitrary position in the vehicle 3A. Instead of voice output, the presence or absence of a traffic event may be inquired by displaying text messages or images on a car navigation screen, a head-up display, or the like.

  Here, as described above, the acquisition unit 51 performs driving status information related to the driving status of the vehicle 3A based on detection signals from a wheel speed sensor, a GPS receiver, a gyro sensor, and an inter-vehicle distance sensor mounted on the vehicle 3A. S31 is acquired. The driving status information S31 is input from the acquisition unit 51 to the timing control unit 52. The timing control unit 52 is based on the driving situation information S31, the vehicle 3A is performing a right turn or a left turn, the vehicle 3A is traveling at a certain speed or more, the vehicle 3A is traveling within an intersection, and In a dangerous situation where the driver's attention of the vehicle 3A becomes distracted, such as when the distance between the vehicle 3A and the preceding and following vehicles is within a certain value, the voice of the question is not output from the speaker 56. The question is voiced after the situation is resolved. This makes it possible to ensure the safety of driving the vehicle 3A. If the dangerous situation is not resolved even after a certain time (for example, several minutes), information indicating that “response is impossible” is transmitted from the in-vehicle device 4A to the traffic information processing device 2. However, the question to the passenger of the vehicle 3A may not be made.

  When a passenger of the vehicle 3A verbally answers the question output from the speaker 56, the answer is a microphone 57 (car navigation system) provided at an arbitrary position (for example, the steering wheel or its vicinity) in the vehicle 3A. The sound is collected and input to the control unit 55 as answer information S21 which is voice information. The control unit 55 transmits the answer information S21 from the transmission unit 54 toward the traffic information processing apparatus 2. Instead of transmitting the reply information S21 as voice information, the control unit 55 may perform simple voice recognition processing to convert it into character string data and send it.

  Note that an agent function in which the in-vehicle device 4A answers the question information S14 received from the traffic information processing device 2 in place of the passenger may be implemented in the in-vehicle device 4A. As described above, the acquisition unit 51 acquires the driving state information S31 based on detection signals of various sensors mounted on the vehicle 3A. The control unit 55 analyzes the question information S14 input from the receiving unit 53, and when the question content is a content that can be answered based on the driving situation information S31, the question information S14 is not output from the speaker 56 by voice. The answer information S21 is created by itself. Then, the created reply information S21 is transmitted from the transmission unit 54 to the traffic information processing apparatus 2.

  For example, when the question information S14 for inquiring whether or not a traffic jam has occurred is input, the control unit 55 refers to the driving status information S31 regarding the latest predetermined period (for example, several tens of minutes). Then, when the driving situation of the vehicle 3A within the predetermined period is a situation where the start, the low-speed running, and the stop are repeated, the control unit 55 determines that the traffic jam has occurred and generates the traffic jam. Answer information S21 with a content of affirming is created. At that time, it is also possible to estimate a traffic jam occurrence point, a traffic jam occurrence time, and the like based on the driving status information S31, and include these pieces of information in the response information S21. In addition, when the average speed of the vehicle 3A within the predetermined period is equal to or greater than a certain value, the control unit 55 determines that no traffic jam has occurred and answers information S21 that denies the occurrence of the traffic jam. Create In addition, when it is not possible to determine whether or not a traffic jam has occurred, the control unit 55 outputs the question information S14 by voice from the speaker 56, thereby entrusting the answer to the passenger. By mounting such an agent function on the in-vehicle device 4A, the number of questions to the passenger can be reduced, so that the burden on the passenger accompanying the answer to the question can be reduced.

  Referring to FIG. 5, receiving means 41 receives answer information S21 from in-vehicle device 4A, stores the received answer information S21 in storage means 42, and inputs it to determination means 43.

  The determination means 43 determines whether or not the traffic event estimated by the estimation means 32 has actually occurred based on the probe information and the vehicle sensing information by analyzing the answer information S21. The analysis of the answer information S21 can be executed by converting the answer information S21 into character string data by a voice recognition process and performing a natural sentence pattern matching process on the character string. For example, a plurality of natural sentences that are supposed to be used for answers such as “congested” and “crowded” are registered in the database, and sentences included in the character string obtained from the answer information S21 Determines whether it matches the natural sentence registered in the database. If the sentence obtained from the response information S21 contains a natural sentence such as “congested” or “crowded”, the “traffic jam occurrence” estimated by the estimating means 32 Is determined to be actually occurring. On the other hand, when a natural sentence such as “no traffic jam” or “smoothly flowing” is included, the traffic event “traffic jam occurrence” estimated by the estimation means 32 has not occurred. judge. The determination unit 43 outputs determination result information S22 indicating whether or not the traffic event estimated by the estimation unit 32 has occurred.

  Here, when the question information S14 is transmitted to the plurality of in-vehicle devices specified by the specifying unit 33, when the traffic information processing apparatus 2 receives the answer information S21 from the plurality of in-vehicle devices, the determining unit 43 determines by the majority vote etc. whether the traffic event which the estimation means 32 estimated actually has generate | occur | produced.

  In addition, when the determination unit 43 determines that the traffic event actually occurs and the related information indicating the cause of the traffic event can be extracted from the answer information S21 by voice recognition processing or the like, The related information is acquired from the answer information S21. For example, if there is a traffic event such as “traffic jam occurrence”, a “ball crossing accident with five passenger cars has occurred at the XX intersection” or “the demonstrators have passed the XX intersection toward the west. The related information indicating the cause of the traffic jam such as “is” is acquired from the response information S21.

  Referring to FIG. 3, when the traffic event estimated by the estimation unit 32 actually occurs based on the determination result information S22, the information providing unit 23 provides the user with traffic event information related to the traffic event. To do. For example, the traffic event information is displayed on a road traffic information display panel installed on the road, and the traffic event information is provided on the car navigation screen of the vehicle by road-to-vehicle communication. At that time, the traffic event information may be provided to an unspecified number of vehicles, or the traffic event information is limited to vehicles that may arrive at the traffic event occurrence point within a predetermined time. May be provided.

  Further, the information providing unit 23 may provide the user with the answer information S21 as the voice information stored in the storage unit 42 (that is, the raw voice of the information provider who has transmitted the answer information S21). . As a result, the user provides information such as “There is a crushing accident at the XX intersection and the vehicle is rolling over. For the time being, the traffic jam is unlikely to be resolved, so it is better to bypass the XX intersection.” Can listen to live audio. In this case, from the viewpoint of privacy protection, it is desirable to perform processing such as shifting the audio frequency by a voice changer or the like to provide the processed audio information.

  Furthermore, when the relevant information is acquired by the determination means 43, the information providing means 23 may provide the relevant information to the user together with the traffic event information. For example, when a traffic jam occurs, not only the traffic event information “Traffic jam occurs” but also “A crash of five passenger cars occurred at the intersection of XX” or “The demonstration team headed west. Provide relevant information indicating the cause of the traffic jam, such as “passing an intersection”. In this example, the user who is traveling toward the XX intersection can select a detour route by determining that the traffic jam is not likely to be resolved for a while if the traffic jam is caused by a crushing accident. If is a passage of demonstrators, it can be determined that the traffic jam will be resolved immediately, and the route to the XX intersection can be selected as it is. Thus, by providing the user with the relevant information along with the traffic event information, the convenience of the user can be improved.

  Referring to FIG. 3, the management unit 24 determines the usefulness of the response information S21 for each in-vehicle device depending on whether the answer information S21 provided from the in-vehicle device is true and useful. Manage in the database. For example, every time the true and useful answer information S21 is provided from the in-vehicle device 4A, the degree of benefit related to the in-vehicle device 4A is incremented by “2”, and the true and useless answer information S21 is provided from the in-vehicle device 4A. In addition, the benefit level related to the in-vehicle device 4A is incremented by “1”, and the usefulness level related to the in-vehicle device 4A is decremented by “1” each time the unanswered answer information S21 is provided from the in-vehicle device 4A.

  By managing the usefulness of the reply information S21 for each in-vehicle device, each time the user provides the useful reply information S21, the user is given a contribution point, and the system usage fee is discounted according to the contribution point grant status. Etc. can be implemented. As a result, it is possible to give the user an incentive for providing information.

  In addition, users who frequently send reply information S21 with low usefulness or incorrect reply information S21, or users who do not send reply information S21 even when question information S14 is sent are managed as non-cooperating users. be able to. Accordingly, for such non-cooperating users, it is possible to take measures such as excluding them from the transmission candidates of the question information S14.

  Furthermore, when the determination means 43 determines the presence or absence of the occurrence of a traffic event based on the answer information S21, it is possible to refer to the cumulative status of the benefit level. Thereby, the reply information S21 from the user whose cumulative value of benefit level is a certain value or more can be regarded as having high reliability, and the reply information S21 can be regarded as important in the determination. Further, when a vehicle on which a user with a cumulative value of benefit level is equal to or greater than a certain value is located near a point where the occurrence of a traffic event is estimated, question information S14 is transmitted to the user. Accordingly, it is possible to obtain highly reliable answer information S21 from the user. As a result, the accuracy of information provided by the information providing unit 23 can be improved.

  As described above, according to the traffic information processing apparatus 2 (and the traffic information processing system 1, the program 13, the traffic information processing method) according to the present embodiment, the question information processing means 21 causes some traffic event to occur. Predetermined inquiries information S14 for inquiring a passenger of a vehicle 3A located near a point estimated to be present whether or not the traffic event has occurred is sent to the in-vehicle device 4A mounted on the vehicle 3A. To send. The answer information processing means 22 receives answer information S21 from the passenger for the question information S14 from the in-vehicle device 4A, and determines whether or not a traffic event has occurred based on the answer information S21. Then, when the answer information processing unit 22 determines that a traffic event has occurred, the information providing unit 23 provides the user with traffic event information regarding the traffic event. Thus, when the occurrence of any traffic event is estimated, a highly reliable answer can be obtained by inquiring the passenger of the vehicle 3A located near the occurrence point about the occurrence of the traffic event. Information S21 can be acquired from the passenger. As a result, it is possible to provide information on the traffic event that has occurred at an early stage even in a situation where the estimation certainty is low due to the small number of samples of traffic information such as vehicle sensing information and probe information.

  In addition, when an event occurs that cannot be directly recognized by vehicle detection information or probe information, such as a traffic accident or a march of a demonstrator, the staff has visited the site to check the event details. Detailed information about the event cannot be provided to the user until the information about the event is collected and the information is input to the system. It was. Therefore, a very large time lag has occurred between the actual occurrence of an event and the time when detailed information regarding the event is provided to the user. On the other hand, the traffic information processing apparatus 2 according to the present embodiment acquires information related to the event from the passenger who witnessed the event, and provides the information to the user. Therefore, the time lag from the occurrence of an event to the provision of information to the user is very small compared to when the staff goes to the site. As a result, the probability that the user will be involved in traffic regulation, traffic congestion, etc. due to the delay in providing information is greatly reduced, which is very useful for the user.

  Moreover, the acquisition means 31 acquires provision intention information S11 which shows the information provision intention of the user who is providing the information regarding a traffic event from the vehicle-mounted apparatus 4A mounted in the vehicle 3A in which the said user is aboard. Then, the transmission unit 34 transmits the question information S14 to the in-vehicle device 4A from which the acquisition unit 31 has acquired the provision intention information S11. Thus, by transmitting the question information S14 to the user who intends to voluntarily provide information regarding the traffic event, the highly reliable answer information S21 can be obtained from the user. As a result, the answer information processing means 22 can accurately determine whether or not a traffic event has occurred.

  Further, the specifying unit 33 specifies another vehicle 3B located around the vehicle 3A that has transmitted the provision intention information S11. And the transmission means 34 transmits question information S14 not only to the vehicle 3A that has transmitted the provision intention information S11 but also to the other vehicle 3B specified by the specifying means 33. In this way, by transmitting the question information S14 to the other vehicle 3B, it is possible to obtain highly reliable answer information S21 from a plurality of users. As a result, the answer information processing means 22 can more accurately determine whether or not a traffic event has occurred.

  In addition, questions to the passenger regarding the traffic event are made by voice output from the in-vehicle device 4A, and answers from the passenger to the question are made by voice input to the in-vehicle device 4A. In this way, by performing the question to the passenger and the answer from the passenger by voice, it is possible to avoid the question and the answer from interfering with driving.

In other words, the program 13 is a program for causing the processing unit 11 as a computer installed in the traffic information processing apparatus 2 to function as the information processing unit 60, the information providing unit 23, and the management unit 24. The processing unit 11 according to the present embodiment includes an information processing unit 60 instead of the question information processing unit 21 and the answer information processing unit 22 in the processing unit 11 (see FIG. 3) according to the first embodiment. It becomes the composition.

  FIG. 9 is a diagram specifically illustrating the function of the information processing means 60. The information processing unit 60 includes a receiving unit 71, a storage unit 72, and an estimation unit 73.

  FIG. 10 is a diagram specifically illustrating the function of the in-vehicle device 4A. The in-vehicle device 4A includes a reception unit 53, a transmission unit 54, a control unit 55, a speaker 56, a microphone 57, and an input unit 58.

  Referring to FIG. 10, when the passenger of vehicle 3 </ b> A confirms an event that may cause some traffic event, the passenger inputs provision intention information S <b> 11 indicating an intention of providing information from input unit 58. . The providing intention information S11 can be input by, for example, pressing a button such as a steering switch provided in the vehicle 3A or operating a panel such as a touch panel of a car navigation system. The provision intention information S11 is wirelessly transmitted from the transmission unit 54 to the traffic information processing device 2 including the identification information of the in-vehicle device 4A. In addition, the control unit 55 that has received the provision intention information S11 outputs, from the speaker 56, a predetermined message asking for input of information, such as “please explain what is happening”.

  Note that the above message may be output by displaying a character message or an image on a car navigation screen, a head-up display, or the like instead of the voice output. Similarly to the first embodiment, in a dangerous situation when the driver's attention of the vehicle 3A is distracted, the provision intention information S11 is not received and the message is not output from the speaker 56. After the dangerous situation is resolved, the provision intention information S11 may be received and the message may be output by voice.

  Next, the passenger will verbally explain the situation of the event he has witnessed. The contents of the explanation by the passenger are collected by the microphone 57 and input to the control unit 55 as provision content information S50 which is voice information. The control unit 55 transmits the provided content information S50 from the transmission unit 54 to the traffic information processing apparatus 2. Instead of transmitting the provided content information S50 as voice information, the control unit 55 may perform simple voice recognition processing to convert it into character string data and transmit it.

  The voice output of the message from the speaker 56 may be omitted. In this case, the passenger of the vehicle 3A can immediately start explaining the situation of the event that he / she has witnessed after inputting the provision intention information S11.

  Referring to FIG. 9, receiving means 71 receives provision intention information S11 and provision content information S50 from in-vehicle device 4A, stores received provision intention information S11 and provision content information S50 in storage means 72, and Input to the estimation means 73.

Moreover, the estimation means 73 estimates the traffic event or event which has generate | occur | produced in the vicinity of 3 A of vehicles by analyzing provision content information S50. The analysis of the provided content information S50 can be executed by converting the provided content information S50 into character string data by a voice recognition process and performing a natural sentence pattern matching process on the character string. For example, a plurality of natural sentences, such as “congested” and “crowded”, which are assumed to be used for answers, are registered in the database and included in the character string obtained from the provided content information S50. It is determined whether the sentence matches the natural sentence registered in the database. If the text obtained from the provided content information S50 includes a natural sentence such as “congested” or “crowded”, the traffic event “traffic jam” occurs. Estimate that it has occurred. Here, when provided content information S50 indicating a traffic event or event having the same content is received from a plurality of in-vehicle devices located at the same point or region, the estimating means 73 indicates that the traffic event is actually It is highly likely that this has occurred.

  Further, the estimation means 73 collects probe information sent from a plurality of vehicles and vehicle detection information sent from a vehicle detector installed on the road, and traffic conditions based on the collected information. By analyzing the above, whether or not a traffic event occurs at a certain point or area is constantly monitored. If the current location of the vehicle 3A overlaps with a point or area where the occurrence of some traffic event is estimated based on the probe information, vehicle sensing information, and the like, the estimation means 73 provides the provided content information S50. It is judged that the possibility that the traffic event indicated by is actually occurring is high.

  In addition, when the related information indicating the cause of the traffic event or the like can be extracted from the provided content information S50 by voice recognition processing or the like, the estimating unit 73 acquires the related information from the provided content information S50. For example, when the occurrence of a traffic event “Traffic jam occurs” is estimated, “A crash of five passenger cars occurred at the XX intersection” or “The demonstrators headed west toward the XX intersection.” The related information indicating the cause of the traffic jam such as “passing” is acquired from the provided content information S50. Here, when related information of the same content is acquired from a plurality of provided content information S50 collected from a plurality of in-vehicle devices located in the same spot or region, the estimating unit 73 determines the related information. It is determined that there is a high possibility that the event indicated by is actually occurring (that is, the credibility of the related information is high).

  If the estimation means 73 determines that there is a high possibility that the traffic event estimated based on the provided content information S50 has actually occurred, the estimation means 73 outputs estimation result information S51 indicating the estimation result.

  Referring to FIG. 8, information providing means 23 provides the user with traffic event information related to a traffic event based on estimation result information S51.

  In addition, the information providing unit 23 provides the user with the provided content information S50 as voice information stored in the storage unit 72 (that is, the raw voice of the information provider who has transmitted the provided content information S50). Also good. In this case, from the viewpoint of privacy protection, it is desirable to perform processing such as shifting the audio frequency by a voice changer or the like to provide the processed audio information.

  Furthermore, when the credibility of the related information acquired by the estimating unit 73 is high, the information providing unit 23 may provide the related information to the user together with the traffic event information. For example, when a traffic jam occurs, not only the traffic event information “Traffic jam occurs” but also “A crash of five passenger cars occurred at the intersection of XX” or “The demonstration team headed west. Provide relevant information indicating the cause of the traffic jam, such as “passing an intersection”.

  Thus, according to the traffic information processing apparatus 2 (and the traffic information processing system 1, the program 13, the traffic information processing method) according to the present embodiment, the information processing means 60 is provided with the provided content information S50 from the passenger. It is received from the device 4A and the occurrence of a traffic event is estimated based on the provided content information S50. And the information provision means 23 provides a user with the traffic event information regarding the said traffic event, when the possibility that the traffic event estimated by the information processing means 60 has actually occurred is high. In this way, when any traffic event occurs, it is possible to acquire the highly reliable provision content information S50 from the passenger of the vehicle 3A located in the vicinity of the occurrence point. As a result, it is possible to provide information on the traffic event that has occurred at an early stage even in a situation where the estimation certainty is low due to the small number of samples of traffic information such as vehicle sensing information and probe information.

  In addition, the passenger can explain the situation of the event that he / she has witnessed with an undefined free expression, instead of answering a standard question from the in-vehicle device 4A. Therefore, since it is possible to avoid a situation in which a deviation occurs between the question content from the in-vehicle device 4A and the content that the passenger wants to explain, the passenger can accurately convey the content that the passenger wants to explain, and as a result, traffic The information processing apparatus 2 can estimate the occurrence of a traffic event based on the accurate provided content information S50. In addition, since there is no waiting time from when the provision intention information S11 is input to when the question information S14 is output by voice, it is possible to eliminate the dissatisfaction of the passenger who feels impatient with the waiting time. . On the other hand, according to the format in which the answer information S21 from the passenger is acquired for the standard question information S14 as in the first or second embodiment, the pattern of the answer contents for the question information S14 is generally predicted. Therefore, it is possible to easily analyze the answer information S21 by the determination unit 43.

  It should be noted that this embodiment and the first or second embodiment can be applied in combination.

  The in-vehicle device 4A stops the voice output of the question information S14 from the speaker 56 and provides it when the provision content information S50 is inputted from the microphone 57 before the question information S14 is outputted from the speaker 56. The content information S50 is transmitted from the transmission unit 54 to the traffic information processing apparatus 2.

  Further, when the traffic information processing apparatus 2 receives the provision content information S50 from the in-vehicle device 4A before transmitting the question information S14 to the in-vehicle device 4A, the traffic information processing apparatus 2 stores the question information S14 to the in-vehicle device 4A.
