[0039] FIG. 2 is a flowchart showing an example of the operation of the information providing system 12 according to this embodiment.

[0040] In step S1, the driving information acquisition unit 28 provided in the vehicle 14 acquires driving information. After that, the process proceeds to step S2.

[0041] In step S2, the driving information transmitting unit 30 provided in the vehicle 14 supplies the acquired driving information to the information processing device 10. After that, the process proceeds to step S3.

[0042] In step S3 (receiving step), the driving information receiving unit 40 provided in the information processing device 10 receives the driving information. After that, the process proceeds to step S4.

[0043] In step S4 (determination step), the determination unit 42 provided in the information processing device 10 determines whether the driver of the vehicle 14 has engaged in unsafe driving based on the driving information received by the driving information receiving unit 40. Specifically, the determination unit 42 determines whether the driver of the vehicle 14 has committed a traffic violation based on the driving information. The determination unit 42 determines that the driver of the vehicle 14 has engaged in unsafe driving when it is determined that the driver of the vehicle 14 has committed a traffic violation. The determination unit 42 also determines whether the driver of the vehicle 14 has performed an abrupt operation based on the driving information. The determination unit 42 determines that the driver of the vehicle 14 has engaged in unsafe driving when it is determined that the driver of the vehicle 14 has performed an abrupt operation. Furthermore, the determination unit 42 determines whether assistance has been provided by a safety driving support system based on the driving information. The determination unit 42 determines that unsafe driving has been engaged in when it is determined that assistance has been provided by the safety driving support system.

[0044] If the determination unit 42 determines that unsafe driving has been performed (YES in step S4), the process proceeds to step S5. If the determination unit 42 determines that unsafe driving has not been performed (NO in step S4), the process proceeds to step S6.

[0045] In step S5 (information generation step), the information generation unit 44 included in the information processing device 10 generates information regarding unsafe driving performed by the driver of the vehicle 14. The information generated by the information generation unit 44 is stored in the storage unit 52. After this, the process proceeds to step S6.

[0046] In step S6 (information provision step), the driving end determination unit 46 included in the information processing device 10 determines whether or not driving of the vehicle 14 has ended based on the driving information received by the driving information receiving unit 40. If the driving end determination unit 46 determines that driving has ended (YES in step S6), the process proceeds to step S7. If the driving end determination unit 46 determines that driving of the vehicle 14 has not ended (NO in step S6), the process proceeds to step S1.

[0047] In step S7, the information providing unit 48 included in the information processing device 10 provides the information generated by the information generating unit 44 to the terminal device 16. Specifically, the information providing unit 48 provides the information generated by the information generating unit 44 to the terminal device 16, for example, after a predetermined time has elapsed since the driving end determination unit 46 determined that driving has ended. The predetermined time can be set as appropriate and may be set to, for example, several minutes or several hours. The predetermined time can also be set by the user operating the terminal device 16. The information providing unit 48 may provide the information generated by the information generating unit 44 to the terminal device 16 at a predetermined time after the driving end determination unit 46 determined that driving has ended. The predetermined time can be set as appropriate and may be set to, for example, 8:00 PM. After this, the process proceeds to step S8.

[0048] In step S8, the display control unit 64 provided in the terminal device 16 causes the display unit 56 to display the information provided by the terminal device 16. In this way, the processing shown in FIG.

[0049] As described above, the information generation unit 44 can generate information regarding unsafe driving performed by the driver of the vehicle 14. As shown in FIGS. 3 and 5 to 7 , the information regarding unsafe driving performed by the driver of the vehicle 14 includes map information 70, questionnaire information 72, and information 74. The display control unit 64 can display information provided from the information provision unit 48 included in the information processing device 10 on the display unit 56. The display control unit 64 can display a display screen including the information provided from the information provision unit 48 on the display unit 56. Specifically, the display control unit 64 can display, for example, a map information display screen 76, a questionnaire display screen 78, an image information display screen 80, etc. on the display unit 56.

[0050] 3 is a diagram showing an example of a map information display screen 76. As shown in FIG. 3, the map information display screen 76 may display map information 70 generated by the information generation unit 44. The map information 70 indicates locations of unsafe driving performed by the driver of the vehicle 14. The map information 70 includes a map 82 showing roads traveled by the vehicle 14 and their surrounding areas. The map 82, for example, indicates a driving route 84, which is the route traveled by the vehicle 14, with a thick line. Multiple types of icons 86 may be displayed on the driving route 84, indicating that unsafe driving has occurred.

[0051] Fig. 4 is a diagram showing an example of an explanation screen 88. As shown in Fig. 4, the display control unit 64 can display, on the display unit 56, an explanation screen 88 for explaining the meanings of multiple types of icons 86. In the example of Fig. 4, nine types of icons 86 are displayed.

[0052] Specifically, the icon 86a indicates failure to stop, and the icon 86b indicates speeding. These icons 86a and 86b indicate suspected traffic violations among unsafe driving.

[0053] The icon 86c indicates sudden braking, the icon 86d indicates sudden steering, and the icon 86e indicates sudden acceleration. These icons 86c to 86e indicate sudden operations that are part of unsafe driving.

[0054] Icon 86f indicates unsafe driving when assistance is provided by the anti-lock brake system, icon 86g indicates unsafe driving when assistance is provided by the skid prevention function, icon 86h indicates unsafe driving when assistance is provided by the road departure prevention function, and icon 86i indicates unsafe driving when assistance is provided by the collision mitigation brake. These icons 86f to 86i indicate unsafe driving that requires assistance from a safe driving assistance system.

[0055] The icons 86a and 86b relating to traffic violations are displayed in red, for example. The icons 86c to 86i relating to sudden operations and safe driving support systems are displayed in yellow, for example. The color, shape, etc. of the icons 86 can be set as appropriate. The multiple types of icons 86 are not limited to the example shown in FIG. 4.

[0056] As shown in FIG. 3 , multiple types of icons 86 are displayed at positions on the travel route 84 corresponding to locations where unsafe driving actually occurred. The user can select an icon 86 displayed on the travel route 84. Specifically, the user can select an icon 86 by tapping on the icon 86 displayed on the travel route 84. When the user selects an icon 86 on the travel route 84, detailed information 90 of the icon 86 can be displayed below the map 82. The detailed information 90 can include the tapped icon 86, a description of the icon 86, location information of the location where the unsafe driving corresponding to the icon 86 occurred, the time when the unsafe driving corresponding to the icon 86 occurred, a questionnaire display selection section 92, an image information display selection section 94, etc. The questionnaire display selection section 92 displays, for example, "Answer reason." The image information display selection section 94 displays, for example, "View the scene."

[0057] 5 is a diagram showing an example of a survey display screen 78a including survey information 72a regarding failure to stop temporarily. When the survey display selection section 92 is selected on the map information display screen 76, the survey display screen 78a is displayed on the display unit 56, for example, as shown in FIG. 5. The survey information 72a generated by the information generation unit 44 may be displayed on the survey display screen 78a. The survey information 72a includes content that asks the driver why they engaged in unsafe driving. Specifically, the survey display screen 78a may display a title display section 96, a question section 98, an answer section 100, a cancel selection section 102, an answer selection section 104, and the like.

[0058] On the questionnaire display screen 78a, the title display section 96 displays, for example, "Answer to the reason." The question section 98 displays content asking about the reason for the unsafe driving of the detailed information 90 displayed on the map information display screen 76. Specifically, when the questionnaire display selection section 92 is selected in a state in which content related to not stopping temporarily is displayed in the detailed information 90 as shown in FIG. 3, the question section 98 displays, for example, "Please tell us the reason for not stopping temporarily."

[0059] The answer section 100 is configured to allow input of an answer to the question section 98. The answer section 100 may display multiple possible answer options. The user may select one or more of the multiple answer options. Specifically, if the question section 98 is about not stopping at a stop sign, it may display "I didn't notice the sign," "I thought it would be okay if I drove slowly," "I thought I had stopped," "There was no stop sign (false detection)," "Someone else was driving," etc. Note that the answer section 100 may allow any text to be input.

[0060] The cancel selection section 102 displays, for example, "Cancel." When the cancel selection section 102 is selected, for example, the answer content of the answer section 100 is canceled, and the map information display screen 76 is displayed on the display section 56. The answer selection section 104 displays, for example, "Answer." When the answer selection section 104 is selected, the answer content is confirmed. In this case, the terminal device 16 can provide the answer content to the developer of the app, etc., via the network 18. This makes it possible to analyze the status of improvement in unsafe driving based on the answers to the questionnaire.

[0061] 6 is a diagram showing an example of a questionnaire display screen 78b including questionnaire information 72b regarding speeding. As shown in FIG. 6, on the questionnaire display screen 78b, a question section 98 displays, for example, "Please tell us the reason for speeding." Furthermore, a response section 100 displays, for example, "I was unaware of the speed limit," "I was aware, but exceeded the speed limit," "I thought I was within the speed limit," "I was not exceeding the speed limit (false detection)," "Someone else was driving," etc.

[0062] 7 is a diagram showing an example of the map information display screen 76. When the image information display selection section 94 is selected on the map information display screen 76, an image information display screen 80 is displayed on the display unit 56, as shown in FIG. 7. On the image information display screen 80, for example, a still image of the point where unsafe driving occurred, which is displayed in the detailed information 90 that was displayed on the map information display screen 76, is displayed. In other words, the image information display selection section 94 is a hyperlink that takes you to the URL of a web page where a still image of the point where unsafe driving occurred in the detailed information 90 is stored.

[0063] The image information display screen 80 may display, for example, a video or still image taken by a camera (such as a drive recorder) of the vehicle 14 at the point where the unsafe driving occurred, which is displayed in the detailed information 90. In this case, the driver of the vehicle 14 can objectively understand the state of his or her driving.

[0064] In this embodiment, the information provided by the information providing unit 48 may be at least one of the questionnaire information 72 and the information 74 .

[0065] According to this embodiment, at least one of the questionnaire information 72 and the information 74 is provided, so that the driver of the vehicle 14 can objectively recognize his or her own unsafe driving. This is expected to reduce unsafe driving.

[0066] Next, a demonstration experiment for confirming the effects of the present invention will be described.

[0067] The demonstration experiment period was one month. The one month before the start of the demonstration experiment period was the pre-demonstration period. During both the pre-demonstration period and the demonstration experiment period, 13 drivers aged 65 or older were surveyed for unsafe driving tendencies. The unsafe driving behaviors surveyed included sudden braking, sudden steering, sudden acceleration, and failure to stop.

[0068] In the demonstration experiment, when a driver of a vehicle 14 engaged in unsafe driving, information about the unsafe driving (map information 70, questionnaire information 72, and information 74) was provided to the terminal device 16. The 13 drivers surveyed (evaluation subjects) were able to access the information about unsafe driving by operating the terminal device 16.

[0069] The results of the demonstration experiment are shown in Figures 8A to 9B. Figure 8A is a graph showing the frequency of sudden braking per unit driving distance. Figure 8B is a graph showing the frequency of sudden steering per unit driving distance. Figure 9A is a graph showing the frequency of sudden acceleration per unit driving distance. Figure 9B is a graph showing the frequency of failure to stop per unit driving distance.

[0070] 8A, the frequency of sudden braking per unit distance traveled during the demonstration experiment was lower than the frequency of sudden braking per unit distance traveled during the pre-demonstration period. Specifically, the median frequency of sudden braking per unit distance traveled during the demonstration experiment was 39% lower than the median frequency of sudden braking per unit distance traveled during the pre-demonstration period.

[0071] 8B, the frequency of sudden steering per unit distance traveled during the demonstration experiment period was lower than the frequency of sudden steering per unit distance traveled during the pre-demonstration period. Specifically, the median frequency of sudden steering per unit distance traveled during the demonstration experiment period was 37% lower than the median frequency of sudden steering per unit distance traveled during the pre-demonstration period.

[0072] 9A, the frequency of sudden acceleration per unit distance traveled during the demonstration experiment period was lower than the frequency of sudden acceleration per unit distance traveled during the pre-demonstration period. Specifically, the median frequency of sudden acceleration per unit distance traveled during the demonstration experiment period was 59% lower than the median frequency of sudden acceleration per unit distance traveled during the pre-demonstration period.

[0073] 9B, the frequency of non-stop driving per unit distance traveled during the demonstration experiment period was lower than the frequency of non-stop driving per unit distance traveled during the pre-demonstration period. Specifically, the median frequency of non-stop driving per unit distance traveled during the demonstration experiment period was 60% lower than the median frequency of non-stop driving per unit distance traveled during the pre-demonstration period.

[0074] According to the results of the above-mentioned demonstration experiment, it was found that providing information regarding unsafe driving to the terminal device 16 allows the driver of the vehicle 14 to objectively recognize his or her own unsafe driving, which is expected to help curb unsafe driving.

[0075] The present invention is not limited to the above-described configuration. At least one of the driving information receiving unit 40, the determination unit 42, the information generating unit 44, the driving termination determination unit 46, and the information providing unit 48 may be provided in the calculation unit 20 of the vehicle 14. That is, for example, the calculation unit 20 of the vehicle 14 may have the determination unit 42 and the driving termination determination unit 46.
