Embodiments for Carrying Out the Invention

[0011] Hereinafter, embodiments of the present invention will be described. The question-providing system according to the embodiments of the present invention includes a question storage unit, a question extraction unit, and a question providing unit. The question storage unit stores, in association with each other, questions regarding driving created based on events occurring in the moving body, driving information, and the driver who caused the event, for a plurality of drivers. The driving information is information obtained from at least one of the driving state and driving position of the moving body before the occurrence of the event. The question extraction unit extracts one question from the questions stored in the question storage unit for another driver different from the recipient, based on the driving information of the recipient before the occurrence of the event caused by the recipient. The question providing unit provides the one question extracted by the question extraction unit to the recipient.

[0012] According to the question providing system of the present embodiment, since questions about other drivers are provided to the recipient, the answers to the provided questions are not just a recollection of the events experienced, so they are likely to leave an impression. Also, since the questions are extracted based on the driving information before the event occurred by the recipient, they are related to situations similar to those at the time when the recipient caused the event, and in this regard as well, they are likely to leave an impression on the recipient. Thus, according to the question providing system of the present embodiment, it is possible to provide questions that are likely to leave an impression on the recipient and have a high educational effect regarding safe driving.

[0013] Here, in the present embodiment, the driving information is information representing at least one of a driving tendency and a road type. The driving tendency includes at least one of violations, hard braking, sharp steering, lane departure, and driving with an inter-vehicle distance shorter than a predetermined length, which were performed before the event. The road type is the type of road that the moving body passed through before the event occurred.

[0014] According to this configuration, since questions are extracted based on driving information related to situations where similar events are likely to occur, such as the driving tendency and the road type, it is possible to provide questions that are even more likely to leave an impression on the recipient and have a high educational effect.

[0015] Also, in the present embodiment, the question extraction unit extracts, as one question, among the questions associated with other drivers, those for which the driving information associated with the question is similar to the driving information of the recipient to a predetermined degree or more.

[0016] According to this configuration, since questions associated with driving information highly similar to the driving information of the recipient are extracted, it is possible to provide questions that are even more likely to leave an impression on the recipient and have a high educational effect.

[0017] In addition, in the present embodiment, both the question storage unit and the question extraction unit are installed in a predetermined server device and perform processing on the server device. Further, the question providing unit is installed in the server device and provides questions to the recipient via a terminal device that is operable by the recipient and connected to the server device via a predetermined network and the network.

[0018] According to this configuration, questions are stored and extracted by a server device with high storage capacity and processing capacity, and questions are provided via a terminal device that is easy for the recipient to use. Therefore, questions can be provided efficiently.

[0019] The question providing method according to the embodiment of the present invention includes a question storage step, a question extraction step, and a question providing step. The question storage step is a step of storing, for a plurality of drivers, questions related to driving created based on events occurring in a moving body, driving information, and the driver who caused the event, in association with each other. The driving information is information obtained from at least one of the traveling state and traveling position of the moving body before the occurrence of the event. The question extraction step is a step of extracting one question from the questions stored in the question storage step for another driver different from the recipient based on the driving information of the recipient before the occurrence of the event caused by the recipient. The question providing step is a step of providing the one question extracted in the question extraction step to the recipient.

[0020] According to the question providing method of the present embodiment, since questions about other drivers are provided to the recipient, the answers to the provided questions are not just a recollection of the experienced events and are likely to leave an impression. Further, since the questions are extracted based on the driving information of the recipient before the occurrence of the event caused by the recipient, they are related to situations similar to those when the recipient caused the event, and in this regard as well, they are likely to leave an impression on the recipient. Thus, according to the question providing system of the present embodiment, it is possible to provide questions that are likely to leave an impression on the recipient and have a high educational effect regarding safe driving.

[0021] In addition, the question-providing program according to the embodiment of the present invention causes a computer to execute the above-described question-providing method.

[0022] According to the question-providing program of the present embodiment, by causing a computer to execute the above-described question-providing method, it is possible to provide questions with a high educational effect regarding safe driving.

[0023] In addition, the storage medium according to the embodiment of the present invention stores the above-described question-providing program.

[0024] According to the storage medium of the present embodiment, by reading out the above-described question-providing program and causing a computer to execute it, it is possible to provide questions with a high educational effect regarding safe driving.

Example

[0025] Hereinafter, an example for solving the problem of providing questions with a high educational effect regarding safe driving will be specifically described with reference to the drawings.

[0026] FIG. 1 is a schematic diagram showing a traffic system to which a question-providing system for providing questions regarding safe driving is applied.

[0027] The traffic system 1 shown in FIG. 1 includes a server device 10, a moving body 20 such as a passenger car, a terminal device 30, and a wireless network 40. In this traffic system 1, a plurality of moving bodies 20 and terminal devices 30 operable by a driver Y of each moving body 20 are connected to the server device 10 via the wireless network 40.

[0028] First, each moving body 20 in this traffic system 1 has the following configuration.

[0029] FIG. 2 is a schematic block diagram showing the configuration provided in the moving body shown in FIG. 1.

[0030] The moving body 20 includes a moving body side communication unit 21, a control unit 22, a drive recorder 23, an event detection unit 24, a position acquisition unit 25, and a traveling state acquisition unit 26. The moving body side communication unit 21 exchanges information with the server device 10 via the wireless network 40. The control unit 22 controls the operations of various devices in the moving body 20 and processes the information acquired by the drive recorder 23, the event detection unit 24, and the position acquisition unit 25. The drive recorder 23 is mounted on the moving body 20 and records the images around it by taking videos. The event detection unit 24 includes an acceleration sensor and detects the occurrence of events such as sudden steering and sudden braking. The position acquisition unit 25 acquires the position of the moving body 20 using the Global Positioning System (GPS). The traveling state acquisition unit 26 acquires the traveling state of the moving body 20 such as brake operation and steering operation.

[0031] In this embodiment, when the event detection unit 24 detects the occurrence of an event, the control unit 22 extracts event front and rear images covering before and after the event from the video taken and recorded by the drive recorder 23. Further, the control unit 22 extracts the position of the moving body 20 acquired by the position acquisition unit 25 during the 10 minutes before the occurrence of the event. Further, the control unit 22 compares the predetermined map information with the position at the time of event occurrence and determines the type of the road that the moving body 20 passed through during the above 10 minutes. The type of road here refers to which of the highway, single road, near an intersection without a traffic signal, and near an intersection with a traffic signal the road corresponds to. Further, the control unit 22 extracts the traveling state of the moving body 20 during the 10 minutes before the occurrence of the event from the traveling state of the moving body 20 acquired by the traveling state acquisition unit 26. Then, the control unit 22 creates event information in which the event front and rear images, the shooting date and time thereof, the type of the road as the shooting location, the position and traveling state during the 10 minutes before the occurrence of the event, and the identifier indicating the driver Y who caused the event are associated with each other. The control unit 22 transmits this event information to the server device 10 via the moving body side communication unit 21.

[0032] FIG. 3 is a schematic block diagram showing a question providing system constructed in the server device shown in FIG. 1.

[0033] The question providing system 100 is a system that is constructed in the server device 10, creates and provides questions regarding safe driving triggered by receiving event information from the moving body 20. Also, the driver Y who caused the event in the moving body 20 which is the source of the event information that triggered this time becomes the recipient who receives the provision of the questions and receives education regarding safe driving. The question providing system 100 includes a server-side communication unit 101, a question creation unit 102, a question storage unit 103, a question extraction unit 104, and a question providing unit 105.

[0034] The server-side communication unit 101 exchanges information with the moving body 20 and the terminal device 30 of the driver Y via the wireless network 40. The question creation unit 102 creates questions regarding safe driving based on the event information sent from the moving body 20. The questions are such that they display a question image representing the situation immediately before the occurrence of the event and ask what happened following that situation to seek an answer. The question storage unit 103 stores questions, driving information, and the identifier of the driver Y who caused the event, in association with each other, for a plurality of drivers Y. The driving information is information obtained from both the driving state and the driving position during the 10 minutes before the occurrence of the event.

[0035] The question storage unit 103 first analyzes the event information and obtains the driving tendency during the 10 minutes before the occurrence of the event. Then, the question storage unit 103 creates driving information representing the driving tendency during the 10 minutes before the occurrence of the event thus obtained and the type of road included in the event information. Then, the question storage unit 103 stores the question, the driving information, and the identifier of the driver Y, in association with each other. The question storage unit 103 executes such processing each time event information is sent from each of the plurality of moving bodies 20 and questions are created, whereby questions and the like are stored for a plurality of drivers Y.

[0036] Based on the driving information of the provider before the event generated by the provider, the question extraction unit 104 extracts one question from the questions stored in the question storage unit 103 for another driver Y different from the provider. Further, the question providing unit 105 provides the one question extracted by the question extraction unit 104 to the provider.

[0037] In the question providing system 100 constructed in the server device 10 of the traffic system 1 described above, a series of processing flows for creating and providing questions regarding safe driving triggered by the reception of event information from the moving body 20 will be described below.

[0038] FIG. 4 is a flowchart showing a processing flow according to a question providing method that is executed when event information is received from a moving body in the question providing system.

[0039] When event information is received, first, a question creation step (step S11) is executed in which the question creation unit 102 creates a question regarding safe driving based on the event information sent from the moving body 20. Next, a question storage step (step S12) is executed in which the created question is stored in the question storage unit 103. Here, as described above, the question is stored in association with the driving information created based on the event information and the identifier of the driver Y.

[0040] FIG. 5 is a diagram showing various information stored in association with the question in tabular form.

[0041] Prior to storing the question, the question storage unit 103 obtains the driving tendency J11 of the 10 minutes of driving before the occurrence of an event including at least one of violations, sudden braking, sudden steering, lane departure, and driving at an inter-vehicle distance shorter than a predetermined distance, which occurred before the event. The driving tendency J11 represents the number of times of each of the above behaviors. Violations include temporary non-stop, speeding, and non-stop at a railroad crossing. The question storage unit 103 obtains such a driving tendency J11 based on the event information of the moving body 20 to be analyzed, the event information of other surrounding moving bodies 20, map information, and the like. Then, the question storage unit 103 creates driving information J1 representing the driving tendency J11 of the 10 minutes before the occurrence of the event thus obtained and the road type J12 included in the event information. In the question storage process (step S12), the question storage unit 103 stores the question in association with the driving information J1 and the identifier J2 of the driver Y. Also, in this embodiment, the identifier J3 of the pre- and post-event images used for creating the question is also associated with the question.

[0042] When the question is stored in the question storage process (step S12) of FIG. 6, subsequently, the question extraction process (step S13) is executed. In the question extraction process (step S13), the driving information J1 created by the question storage unit 103 is used for the provider. The question extraction unit 104 first extracts questions of other drivers Y associated with identifiers J2 different from that of the provider. Further, from among the questions of those other drivers Y, those associated with driving information J1 that is similar to the driving information J1 of the provider to a predetermined degree or more are extracted as one question. Here, the similarity means that the driving tendency J11 of the 10 minutes before the occurrence of the event and the road type J12 included in the event information match to a predetermined degree or more.

[0043] Then, the question providing step (step S14) is executed in which the question providing unit 105 provides the question thus extracted to the provider. The provision at this time is performed by transmitting the question to the terminal device 30 operable by the provider via the server-side communication unit 101. With the execution of this question providing step (step S14), the processing of the question providing method shown in the flowchart of FIG. 6 ends.

[0044] And in the terminal device 30 that has received the question provided in this way, education regarding traffic safety is carried out by having the recipient display the question and provide an answer.

[0045] FIG. 6 is a schematic diagram showing an example of a state where the recipient displays the question and provides an answer.

[0046] The question 50 is composed of an image and text displayed on the display screen 31 of the recipient's terminal device 30. Before providing an answer, a question image 51, a question text 52, answer options 53, and an answer button 54 are displayed, and after providing an answer, an answer image 55 is displayed. The question image 51 is an image representing the situation immediately before the occurrence of an event. The question text 52 is a text asking what happened following this question image 51. Also, four answer options including the correct answer 531 are set for the answer options. And the answer image 55 is an image representing the situation immediately after the occurrence of the event.

[0047] The recipient who has seen the question image 51 before providing an answer selects one answer from among the four options and clicks the answer button 54. If it is the correct answer, a circle mark is displayed on the display screen 31 and the answer image 55 is displayed. Also, if it is incorrect, a cross mark is displayed on the display screen 31 and the answer image 55 is displayed. In the example of FIG. 6, for the correct answer 531 of "about to collide with an oncoming vehicle", the option of "about to collide with the vehicle ahead" has been selected, and a cross mark is displayed for this.

[0048] Note that the recipient referred to here is not limited to the driver Y of any of the moving bodies 20 constituting the traffic system 1 in FIG. 1 to which the question providing system 100 of the present embodiment is applied. Anyone who has an opportunity to drive a certain moving body, has a unique identifier, and can acquire driving information can be the recipient for the above question 50.

[0049] In this embodiment, a questionnaire providing program for causing a computer to execute the questionnaire providing method represented by the flowchart of FIG. 4 is stored in a predetermined storage unit of the server device 10 or in a storage medium separate from the server device 10. Further, the storage medium storing this questionnaire providing program is not limited to the storage medium installed in the server device 10, and may be a known portable storage medium or a storage medium installed in another server connected to the server device 10 via a network.

[0050] According to the embodiment described above, since the questionnaire 50 about the other driver Y is provided to the recipient, the answer to the provided questionnaire 50 is not just a recollection of the experienced event, so it is easy to leave an impression. Further, since the questionnaire 50 is extracted based on the driving information J1 before the event generated by the recipient, it is related to a situation similar to when the recipient generated the event, and also in this regard, it is easy to leave an impression on the recipient. Thus, according to this embodiment, it is possible to provide a questionnaire 50 that is easy to leave an impression on the recipient and has a high educational effect regarding safe driving.

[0051] Here, in this embodiment, the driving information J1 is information representing the driving tendency J11 and the road type J12. According to this configuration, since the questionnaire 50 is extracted based on the driving information J1 related to a situation where similar events are likely to occur, namely the driving tendency J11 and the road type J12, it is possible to provide a questionnaire 50 that is even easier to leave an impression on the recipient and has a high educational effect.

[0052] Also, in this embodiment, the questionnaire extraction unit 104 extracts, as one questionnaire 50, the one associated with the driving information J1 that is similar to the driving information J1 of the recipient to a predetermined degree or more. According to this configuration, it is possible to provide a questionnaire 50 that is even easier to leave an impression on the recipient and has a high educational effect.

[0053] In this embodiment, both the question storage unit 103 and the question extraction unit 104 are installed in the server device 10 and perform processing on the server device 10. Further, the question providing unit 105 is installed in the server device 10 and provides the question 50 to the recipient via the recipient's terminal device 30 and the network. According to this configuration, the question 50 is stored and extracted by the server device 10 with high storage capacity and processing capacity, and the question 50 is provided via the terminal device 30 that is easy for the recipient to use, so that the question 50 can be provided efficiently.

[0054] Note that the present invention is not limited to the embodiments described above, and includes other configurations and the like that can achieve the object of the present invention, and modifications and the like as shown below are also included in the present invention.

[0055] For example, in the above-described embodiment, the moving body 20 as a vehicle such as a passenger car is exemplified. However, the moving body is not limited to a passenger car or the like, and may be a large vehicle such as a truck or a bus, and the specific type of the moving body is not questioned.

[0056] Further, in the above-described embodiment, a form in which the question 50 regarding safe driving is created based on the moving image and event information of the drive recorder 23 acquired by the moving body 20 is exemplified. However, the question 50 is not questioned about the specific creation form and question content as long as it is a question 50 regarding driving created based on an event that occurred in the moving body.

[0057] In the above-described embodiments, an example is shown in which the driving information J1 is information representing the driving tendency J11 based on the running state of the moving body 20 and the road type J12 based on the running position of the moving body 20. However, the driving information is not limited to this, and as long as it is information obtained from at least one of the running state and the running position before the occurrence of the event, it may be information representing only one of, for example, the driving tendency and the road type. Also, in the above-described embodiments, as the driving tendency J11, an example is shown in which it includes all of violations, sudden braking, sudden steering, lane departure, and driving at a vehicle-to-vehicle distance shorter than a predetermined value, which were performed before the occurrence of the event. However, the driving tendency is not limited to such a form, and as long as it includes at least one of these items, the specific item configuration is not questioned. By using the driving information representing only one of the driving tendency including at least one of such items and the road type, it is possible to provide the question 50 that is more likely to remain in the impression of the recipient and has a high educational effect, as described above.

[0058] Also, in the above-described embodiments, an example is shown in which the question extraction unit 104 extracts, from among the questions 50 associated with another driver Y, those associated with driving information J1 that is similar to the driving information J1 of the recipient to a predetermined degree or more. However, regarding the extraction of the question 50, as long as it is extracted based on the driving information J1 of the recipient from among the questions 50 of another driver Y, the specific extraction form is not questioned. However, by using the similarity of the driving information J1 for extraction, it is possible to provide the question 50 that is more likely to remain in the impression of the recipient and has a high educational effect, as described above.

[0059] In the above-described embodiment, a form is exemplified in which the question storage unit 103 and the question extraction unit 104 perform processing on the server device 10, and the question providing unit 105 provides the question 50 to the recipient via the terminal device 30. However, instead of performing extraction of the question 50 and the like on the server device 10, it may be performed on the terminal device 30. However, as described above, by aggregating various information in the server device 10 having a high processing capacity and performing processing, the question 50 can be provided efficiently.
