[0015] The functions of the information processing device 10 or terminal device 20 are realized by executing a program according to this embodiment on a processor corresponding to the control unit 11 or control unit 21. In other words, the functions of the information processing device 10 or terminal device 20 are realized by software. The program causes the computer to perform the operations of the information processing device 10 or terminal device 20, thereby causing the computer to function as the information processing device 10 or terminal device 20. In other words, the computer functions as the information processing device 10 or terminal device 20 by performing the operations of the information processing device 10 or terminal device 20 according to the program.

Some or all of the functions of the information processing device 10 or terminal device 20 may be realized by a dedicated circuit corresponding to the control unit 11 or control unit 21. In other words, some or all of the functions of the information processing device 10 or terminal device 20 may be realized by hardware.

[0016] Referring to Figure 2, the operation of System 1 according to this embodiment will be described. In the following, communication between the information processing device 10, the terminal device 20, and the vehicle 30 and external devices is performed via the communication unit 13, the communication unit 23, and the communication unit 33 and the network 40, respectively.

[0017] In S1, the control unit 31 of the vehicle 30 transmits sensor information to the information processing device 10. The control unit 31 may transmit sensor information continuously. The sensor information includes values ​​related to the user's driving actions, such as speed, acceleration, steering angle, ignition on or off, and power on or off, as well as images of the vehicle's interior captured by a camera. In S2, the control unit 11 of the information processing device 10 receives sensor information from the vehicle 30. In S3, the control unit 11 generates trip information that shows each of the multiple trips along with the person who was in the vehicle 30. A trip refers to the period from when the vehicle 30's ignition is turned on until it is turned off, or from when the power is turned on until it is turned off. The control unit 11 may analyze the images captured during that period using any image analysis processing technique to identify the person who was in the vehicle 30. The control unit 11 may receive identification information from the vehicle 30 indicating the person who was in the vehicle 30 and identify the person who was in the vehicle 30 based on the identification information. The identification information may be information entered by the person riding in the vehicle 30 via the input / output unit 34 each time the trip is performed. The identification information may also be information acquired by the control unit 31 of the vehicle 30 through short-range wireless communication with the terminal device or smart key of the person riding in the vehicle 30.

[0018] The control unit 11 may acquire schedule information indicating the user's schedule and generate trip information that also indicates the schedule based on the schedule information. The schedule information includes the name and time of the scheduled event. The control unit 11 may receive the schedule information from the terminal device 20 or from an external device. If at least a portion of the time of the scheduled event overlaps with the time of the trip, the control unit 11 generates trip information that also indicates the trip and the name of the scheduled event. By outputting trip information that also indicates the schedule to the user, it becomes easier for the user to recall the purpose of driving, such as commuting or taking children to and from school, related to past trips, and it becomes easier for the user to select a desired trip in S7.

[0019] In S4, the control unit 11 transmits trip information to the terminal device 20. In this example, the control unit 11 transmits information indicating three trips T1 to T3 to the terminal device 20. In S5, the control unit 21 of the terminal device 20 receives the trip information. In S6, the control unit 21 outputs the trip information via the input / output unit 24. The control unit 21 may output the trip information arranged in time series or may output it for each identified person. Table 1 is an example of trip information indicating each trip in time series, which is output to the input / output unit 24. Referring to Table 1, the persons who were riding during each trip, as identified by the information processing device 10, are displayed.

[0020]

Table 1

[0021] In S7, the control unit 21 receives the user selection of the target trips to be included in the report via the input / output unit 24. In this example, suppose user A selects trips T1 and T3, which were driven only by A. In S8, the control unit 21 transmits selection information indicating the user selection to the information processing device 10. In S9, the control unit 11 of the information processing device 10 receives the selection information. In S10, the control unit 11 creates a report on the target trips based on the sensor information and the selection information. In this example, the control unit 11 creates a report for trips T1 and T3. The control unit 11 identifies and analyzes the sensor information acquired from the vehicle 30 during the target trips indicated by the selection information, and creates a report that includes driving characteristics showing the driving trends during those trips. The control unit 11 may diagnose the driving characteristics based on the average or median value of the values ​​detected by various sensors related to multiple target trips. For example, the control unit 11 may diagnose the driving characteristics as sporty type if the median number of sudden accelerations above a predetermined value detected by the acceleration sensor across multiple target trips is equal to or greater than the first threshold. The control unit 11 may diagnose the driving characteristics as eco-type if the median number of sudden accelerations above a predetermined value is less than the first threshold, and the median number of sudden steering angle changes detected by the steering angle sensor is less than the second threshold. The control unit 11 may diagnose the driving characteristics as safe driving type if the median number of sudden accelerations above a predetermined value is less than the first threshold, and the median number of sudden steering angle changes is equal to or greater than the second threshold. However, the control unit 11 may, for example, weight the values ​​detected by each sensor to calculate a score for each driving characteristic and create a report including the score. For example, the control unit 11 calculates a score by multiplying the number of sudden accelerations or sudden decelerations detected by the acceleration sensor by a weight set in advance for each type. The weights may be set, for example, to be large for sporty driving, medium for eco-driving, and small for safe driving. The control unit 11 calculates a score by multiplying the number of sudden steering angle changes detected by the steering angle sensor by a weight predetermined for each type. The weights may be set, for example, to be large for sporty driving, medium for safe driving, and small for eco-driving. The report may include an image that represents a combination of multiple driving characteristics.For example, the report may include an image of each driving characteristic represented by a figure with a larger area and placed in the front as the score is larger. The figure may be any shape such as a circle or a square.

[0022] In S11, the control unit 11 acquires news information indicating news related to the driving diagnosis shown in the report. The control unit 11 may acquire news information related to the driving characteristic with the largest score. The control unit 11 may read out from the storage unit 12 the news information stored in advance in association with the driving characteristic, or may receive the news information from an external device. The news information includes, for example, news about new products or events of vehicle accessories. The accessories include a 360-degree monitor that can overview the surroundings of the vehicle 30, an auxiliary monitor that shows a blind spot area such as the side or rear of the vehicle 30, or tires. The events include a safe driving lecture or a driving technique lecture. The control unit 11 acquires, for example, news information about a new product of an auxiliary monitor related to the safe driving type and the holding of a safe driving lecture. In S12, the control unit 11 transmits the report information indicating the report and the news information to the terminal device 20. In S13, the control unit 21 of the terminal device 20 receives the report information and the news information and outputs them via the input / output unit 24. For example, the control unit 21 outputs, via the input / output unit 24, a report indicating a diagnosis of "safe driving" as a driving characteristic and news information notifying the sale of a 360-degree monitor. The control unit 21 may output the report information and the news information received this time after outputting the report received from the information processing device 10 last time. Then, the operation of the system 1 ends.

[0023] As one variation, the information processing device 10 may receive information from the terminal device 20 indicating the desired driving characteristics (hereinafter referred to as "desired characteristics") that the user wants to achieve, further acquire action information indicating an action plan corresponding to the desired characteristics, and transmit it to the terminal device 20 to notify the user. The action information is various information related to driving or the vehicle 30 that is associated with each driving characteristic, and may be pre-set and stored in the storage unit 12. The action information includes driving courses, driving techniques, or methods of using the functions of the vehicle 30 that correspond to the desired characteristics. For example, if the user's desired characteristics are sports type, the control unit 11 acquires action information that is pre-associated with the sports type, such as "It is recommended to turn on sports mode in section A," which suggests switching to the sports mode function, and transmits it to the terminal device 20. Section A may be a section included in the driving route identified by the control unit 11 from the position information acquired by the positioning unit 36 ​​of the vehicle 30. For example, if the user's desired characteristics are safe driving type, the control unit 11 transmits action information that is pre-associated with the safe driving type, indicating how to use the 360-degree monitor, to the terminal device 20. Action information may include announcements of new products or events for 30 vehicle accessories tailored to desired characteristics.

[0024] The information processing device 10 may, based on the location information of the vehicle 30, transmit advice information to the vehicle 30 indicating driving advice that corresponds to the user's desired characteristics when the vehicle 30 passes near a predetermined geographical point. The driving characteristics, the coordinates of the point, and the advice information may be pre-associated and stored in the storage unit 12. For example, the driving characteristic "safe driving," the road R with sharp curves, and the advice information "be careful as the curve is sharp" may be pre-associated and stored in the storage unit 12. Based on the location information of the vehicle 30, the control unit 11 transmits advice information indicating driving advice that corresponds to the desired characteristics when the vehicle 30 passes a point associated with the desired characteristics. When the vehicle 30 passes the point, the advice information is displayed on the input / output unit 34, and by looking at this information and driving, the user can bring their driving closer to the desired characteristics. In S10 described above, the control unit 11 of the information processing device 10 may create a report that includes how close the user was able to get to the desired characteristics according to the action plan or driving advice.
