Description

Technical Field

[0001] The invention relates to a driving diagnosis system for implementing driving diagnosis of a monitored object. Background Art

[0002] In recent years, a driving diagnosis of a driver has been implemented. For example, Japanese Patent Application Laid-Open No. 2023-85099 discloses a technology that compares standard driving skills with newly diagnosed driving skills based on driving diagnosis, and identifies driving items in which driving skills have changed. Also disclosed is a technology that prompts the driver or guardian with the driving items in which driving skills have changed and the driving skills corresponding to the driving items.

[0003] Furthermore, Japanese Patent Application Laid-Open No. 2023-85100 discloses a method of performing a driving diagnosis of a driver based on vehicle information and providing a benefit corresponding to the driving diagnosis result to a beneficiary. Summary of the invention

[0004] However, when the guardian has a high sense of privacy, the guardian may feel uneasy about disclosing all diagnostic items and use of the driving skill application to the guardian as described in Japanese Patent Application Laid-Open No. 2023-85099.

[0005] Therefore, an object of the present disclosure is to provide a driving diagnosis system that a subject of supervision can use with confidence.

[0006] The driving diagnosis system disclosed in the present invention comprises a driving diagnosis device, a first terminal of a guardian object, and a second terminal of a guardian, and implements driving diagnosis of the guardian object. The driving diagnosis system is characterized in that:

[0007] The driving diagnosis device includes a processor for performing information processing,

[0008] The processor implements the following processing, namely:

[0009] Get vehicle information;

[0010] Performing driving diagnosis of the monitored subject for a plurality of diagnostic items based on the acquired vehicle information;

[0011] obtaining, from the first terminal of the monitored object, a disclosure range of each of the diagnostic items to the monitor;

[0012] Extracting the diagnostic information included in the publicly available range as monitoring information;

[0013] The extracted guardianship information is sent to the second terminal of the guardian.

[0014] In this way, since the guardian can set the scope of disclosure to the guardian, even the guardian who is highly conscious of privacy can use the driving diagnosis system with confidence.

[0015] In the driving diagnosis system disclosed in the present invention, it can also be set as follows:

[0016] The first terminal of the monitored object displays a plurality of configuration files, wherein the configuration files are associated with the plurality of diagnostic items or the contents of each diagnostic item.

[0017] The plurality of diagnostic items or the content of each diagnostic item associated with the profile selected by the guardian are transmitted to the driving diagnosis device as the disclosure range to the guardian.

[0018] This allows the subject of supervision to easily send the publicly available range to the driving diagnosis device.

[0019] In the driving diagnosis system disclosed in the present invention, it can also be set as follows:

[0020] The disclosed range is set corresponding to a plurality of levels of privacy.

[0021] This allows the subject of supervision to easily send the publicly available range to the driving diagnosis device according to the privacy level.

[0022] In the driving diagnosis system disclosed in the present invention, it can also be set as follows:

[0023] A plurality of the configuration files are set according to the usage scenarios of the vehicle.

[0024] As a result, the subject of supervision can easily send the publicly available range to the driving diagnosis device according to the usage scenario of the vehicle.

[0025] In the driving diagnosis system disclosed in the present invention, it can also be set as follows:

[0026] The driving diagnosis device determines the safe driving level of the monitored object and sends the safe driving level to the first terminal of the monitored object.

[0027] The first terminal of the subject of supervision limits the profiles that the subject of supervision can select based on the received safe driving level.

[0028] Thus, for example, when the safe driving level is high, a profile with fewer public items and a higher privacy level can be selected, while when the safe driving level is low, a profile with a higher privacy level cannot be selected. Therefore, an appropriate profile can be selected according to the safe driving level of the monitored person.

[0029] The present disclosure can provide a driving diagnosis system that a guardian can use with confidence. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Hereinafter, the driving diagnosis system 100 according to the embodiment will be described with reference to the accompanying drawings. Figure 1 As shown, the driving diagnosis system 100 includes a vehicle 10, a server 30 as a driving diagnosis device, a first terminal 40 as a portable terminal of a monitored object, and a second terminal 140 as a portable terminal of a monitor. The vehicle 10 is equipped with an in-vehicle terminal 20. The in-vehicle terminal 20, the server 30, the first terminal 40, and the second terminal 140 are connected to each other via a network 90. Figure 1 In the example, one vehicle 10, one vehicle terminal 20, one first terminal 40, and one second terminal 140 are connected to one server 30. However, the number of vehicles 10, vehicle terminals 20, first terminals 40, and second terminals 140 is not limited thereto, and may be two or more.

[0048] like Figure 2 As shown, the vehicle 10 includes a plurality of electronic control units (ECUs) 11 , a plurality of vehicle-mounted devices 13 , and a vehicle-mounted terminal 20 .

[0049] The ECU 11 includes an Advanced Driver Assistance System-ECU (ADAS-ECU) 11A, a steering ECU 11B, a brake ECU 11C, an engine ECU 11D, and an auxiliary machinery ECU 11E. The ADAS-ECU 11A, the steering ECU 11B, the brake ECU 11C, the engine ECU 11D, and the auxiliary machinery ECU 11E are connected to each other via a bus 12, so that information can be transmitted and received to each other. In addition, the vehicle 10 may also include ECUs other than these.

[0050] The ADAS-ECU 11A performs comprehensive control of the advanced driver assistance system. A vehicle speed sensor 13A, a yaw rate sensor 13B, and an external sensor 13C constituting the vehicle-mounted device 13 are connected to the ADAS-ECU 11A.

The external sensor 13C includes, for example, a camera that captures the surroundings of the vehicle 10, a millimeter-wave radar that transmits detection waves and receives reflected waves, and a radar that scans the front of the vehicle 10.

[0051] The steering ECU 11B controls the power steering. The steering ECU 11B is connected to a steering angle sensor 13D and a steering actuator 13E constituting the vehicle-mounted device 13. The steering angle sensor 13D is a sensor for detecting the steering angle of the steering wheel. The steering actuator 13E steers the steering wheel of the vehicle 10 according to the driver's operation.

[0052] The brake ECU 11C controls the brake system of the vehicle 10. The brake ECU 11C is connected to a brake actuator 13F constituting the vehicle-mounted device 13. The brake actuator 13F drives the brakes of the vehicle 10 in accordance with the operation of the driver.

[0053] The engine ECU 11D controls the engine of the vehicle 10. The engine ECU 11D is connected to a throttle actuator 13G and a sensor component 13H constituting the vehicle-mounted device 13. The throttle actuator 13G drives the throttle of the engine according to the operation of the driver. The sensor component 13H includes, for example, an oil temperature sensor for measuring the oil temperature of the engine oil, an oil pressure sensor for measuring the oil pressure of the engine oil, and a rotation sensor for detecting the rotation speed of the engine.

[0054] like Figure 2As shown, the vehicle terminal 20 is a computer including a CPU 21, a memory 22, a wireless communication interface 23 and an in-vehicle communication interface 24. The CPU 21, the memory 22, the wireless communication interface 23 and the in-vehicle communication interface 24 are connected together using an internal bus 25.

[0055] The CPU 21 is a processor that performs information processing. The memory 22 stores a control program 26 and control data 27 for executing the control program 26. The CPU 21 executes the control program 26 stored in the memory 22 to realize various control operations.

[0056] The in-vehicle communication interface 24 is connected to the bus 12 of the vehicle 10. Vehicle information related to the state and control of the vehicle 10 is collected from the ADAS-ECU 11A, steering ECU 11B, brake ECU 11C, engine ECU 11D, and auxiliary machinery ECU 11E of the vehicle 10 via the bus 12 according to the CAN protocol.

[0057] The wireless communication interface 23 is a wireless communication module connected to the network 90 and used to communicate with the server 30 .

[0058] like Figure 3 As shown, the server 30 is a computer including a CPU 31 as a processor for implementing information processing, a memory 32 for storing data, and a wireless communication interface 33. The CPU 31, the memory 32, and the wireless communication interface 33 are connected together using an internal bus 34. The wireless communication interface 33 is a wireless communication module connected to the network 90 and used to communicate with the vehicle-mounted terminal 20, the first terminal 40, and the second terminal 140.

[0059] The memory 32 stores a processing program 35, processing program data 36, ​​a diagnostic standard database 37, a diagnostic history database 38, a user information database 39, and a monthly comprehensive evaluation disclosure range database 39A. The memory 32 may also store other programs and databases.

[0060] The processing program 35 includes a driving diagnosis program for performing driving diagnosis of the driver of the vehicle 10, and a monitoring information extraction program for extracting diagnostic information included in the public range as monitoring information. The processing program 35 is executed by the CPU 31. The processing program data 36 temporarily stores data when the CPU 31 executes the processing program 35, and stores setting values ​​and the like required for the execution of the processing program 35. The operation of the server 30 is realized by the CPU 31 executing the processing program 35.

[0061] like Figure 4As shown, the diagnostic standard database 37 is a database that stores the evaluation index of each diagnostic item when the CPU 31 performs driving diagnosis in a manner of establishing an association with the standard value of the score. The diagnostic standard database 37 stipulates the following situation, that is, when the diagnostic item is accelerator operation, the maximum acceleration is used as an evaluation index. In addition, the diagnostic standard database 37 stipulates the following situation, that is, the maximum acceleration is greater than A as the standard value for making the score of the accelerator operation 1, and the maximum acceleration is less than B as the standard value for making the score of the accelerator operation 3. And the following situation is stipulated, that is, the maximum acceleration is between A and B as the standard value for making the score of the accelerator operation 2. In addition, the larger the numerical value of the score, the higher the level of safe driving.

[0062] Similarly, the diagnosis standard database 37 stipulates that when the diagnosis item is brake operation, the maximum deceleration is used as an evaluation index, and the maximum deceleration of C or more is used as a standard value for making the score of the brake operation 1. It is also stipulated that the maximum deceleration is less than D as a standard value for making the score of the brake operation 3, and the maximum deceleration is between C and D as a standard value for making the score of the brake operation 2. In addition, the diagnosis standard database 37 stipulates that when the diagnosis item is steering wheel operation, the maximum lateral acceleration is used as an evaluation index. It is also stipulated that the maximum lateral acceleration is greater than E as a standard value for making the score of the steering wheel operation 1, the maximum lateral acceleration is less than F as a standard value for making the score of the steering wheel operation 3, and the maximum lateral acceleration is between E and F as a standard value for making the score of the steering wheel operation 2. Furthermore, the diagnosis standard database 37 stipulates that, when the diagnosis item is the inter-vehicle distance, the length of the inter-vehicle distance is used as the criterion for the score of the inter-vehicle distance. Also, when the diagnosis item is recognition and judgment, the proximity warning is used as the evaluation index, the action of the emergency brake is used as the criterion for the score 1 of recognition and judgment, the absence of warning is used as the criterion for the score 3, and the presence of warning is used as the criterion for the score 2.

[0063] like Figure 5 As shown, the diagnostic history database 38 is a database that stores various items such as driving scene extraction time, driving scene, accelerator operation score, brake operation score, steering wheel operation score, vehicle distance score, cognition and judgment score, number of danger avoidance operations, safe driving level, driving distance, and driving time for each registered monitoring object stored in the user information database 39. Here, the driving scene includes starting, accelerating, decelerating, stopping, turning, lane changing, merging, parking, etc. In addition, acceleration, stopping, merging, and parking are omitted from the illustration.

[0064] like Figure 6 As shown, the user information database 39 is a database that stores the guardianship object name, guardianship object age, gender, driving experience years, guardian name, safe driving level judgment result, and public range setting status in an associated manner. The guardianship object is, for example, an elderly person such as guardianship object AAA to DDD. Although the guardians aaa to ddd are often their children, it is not limited to this. For example, it can also be set that the guardianship object is a child who has obtained a driver's license like EEE, and the guardian is their parent eee.

[0065] Here, the safe driving level judgment result stores, for example, the latest monthly safe driving level. For example, in the case of the guardian EEE, if the number of years of driving experience is short and the monthly safe driving level has not been judged, the text "NA" is stored. The public range setting state stores whether the monthly comprehensive evaluation, driving distance, driving time, and number of danger avoidance operations set by the guardian through the first terminal 40 can be disclosed to the guardian's second terminal 140.

[0066] like Figure 7 As shown, the monthly comprehensive evaluation public scope database 39A stores whether the safe driving level, accelerator operation score, brake operation score, steering wheel operation score, vehicle distance score, and cognition and judgment score in the monthly comprehensive evaluation set by the guardian through the first terminal 40 can be disclosed to the guardian's second terminal 140.

[0067] Here, the driving distance, driving time, number of hazard avoidance operations, safe driving level, accelerator operation score, brake operation score, steering wheel operation score, vehicle distance score, and cognition and judgment score constitute the diagnostic information of the result of the driving diagnosis.

[0068] like Figure 8 As shown, the first terminal 40 as a portable terminal of the monitored object is a smart phone including a CPU 41 as a processor for information processing, a memory 42 for storing data, a touch panel 43 for displaying and inputting information, and a wireless communication interface 44. The CPU 41, the memory 42, the touch panel 43 and the wireless communication interface 44 are connected together using an internal bus 45. The operation of the first terminal 40 is realized by the CPU 41 executing an application 46.

[0069] The memory 42 stores an application 46 for performing driving diagnosis, application execution data 47, and a GUI database 48. The application execution data 47 temporarily stores data when the CPU 41 executes the application 46, and stores setting values ​​and the like required for executing the application 46.

[0070] In the GUI database 48, there are stored Figures 9 to 12 As shown, the image data of the home screen 51 , the publicable range initial setting screen 53 , the publicable range setting screen 54 of the monthly comprehensive evaluation, and the second and subsequent publicable range setting screens 55 are displayed on the touch panel 43 .

[0071] like Fig. 9 As shown, the home screen 51 is a screen displayed when the application 46 for implementing driving diagnosis is executed. In the home screen 51, the display date and time, fuel consumption rate, number of danger avoidance operations, driving distance, driving time and monthly comprehensive evaluation are displayed. The monthly comprehensive evaluation displays the scores of each item of safe driving level, accelerator operation, brake operation, steering wheel operation, inter-vehicle distance and cognition and judgment. The score of each item is displayed in a graph. As described previously, the driving distance, driving time, number of danger avoidance operations, safe driving level, accelerator operation score, brake operation score, steering wheel operation score, inter-vehicle distance score, and cognition and judgment score constitute the diagnostic information of the result of driving diagnosis. The initial setting screen 53 of the publicly available range, the setting screen 54 of the monthly comprehensive evaluation of the publicly available range, and the setting screen 55 of the second and subsequent publicly available range will be explained later together with the description of the work.

[0072] Hardware structure and reference of the guardian's second terminal 140 Figure 8 The hardware structure of the first terminal 40 described above is the same. However, since the input of the publicly accessible range is not implemented in the second terminal 140, the GUI database 48 stores Fig. 9 The image data of the home screen 51 shown is shown. However, the public range initial setting screen 53, the public range setting screen 54 of the monthly comprehensive evaluation, and the second and subsequent setting screens 55 of the public range are not stored.

[0073] Next, in reference Figures 13 to 16 At the same time, the operation of the driving diagnosis system 100 according to the embodiment will be described.

[0074] like Fig.13As shown, in the driving diagnosis system 100, the diagnostic information of the monitored object that can be disclosed to the guardian from the first terminal 40 is pre-registered in the user information database 39 and the monthly comprehensive evaluation disclosure range database 39A of the server 30. The server 30 receives vehicle information from the vehicle terminal 20 mounted on the vehicle 10, and performs driving diagnosis processing of the monitored object based on the received vehicle information, and stores the diagnostic information in the diagnosis history database 38 while sending it to the first terminal 40 of the monitored object. In addition, the server 30 extracts the diagnostic information included in the disclosure range as the monitoring information by referring to the user information database 39 and the monthly comprehensive evaluation disclosure range database 39A, and sends the extracted monitoring information to the second terminal 140 of the guardian.

[0075] Below, in reference Figures 14 to 16 The operation of the driving diagnosis system 100 will be described in detail with reference to the flowchart of FIG.

[0076] First, in reference Fig.14 The CPU 41 of the first terminal 40 executes the application 46 for implementing driving diagnosis stored in the memory 42. Fig.14 As shown in step 101, the CPU 41 determines whether to implement the initial setting of the public range. Figure 1 If the judgment is "yes" in step 101, proceed to Figure 1 Step 102, and referring to the GUI database 48, displays on the touch panel 43 Fig.10 The disclosed range initial setting screen 53 is shown. Fig.10 As shown, on the publicable range initial setting screen 53 , a plurality of profiles corresponding to the usage scenes of the vehicle 10 such as “daily use”, “long trip”, and “night” are displayed.

[0077] like Fig.14 As shown in step 103, the monitored object operates the touch panel 43 and sets one of the multiple configuration files to "on" to select the configuration file. Fig.14 As shown in step 104 of the present invention, the default privacy level and the default settings for sharing each item with the guardian are displayed in the lower part of the screen. Fig.10 In the example shown, the default privacy level is 1, and the screen showing the sharing of items such as monthly comprehensive evaluation, driving distance, driving time, and number of hazard avoidance operations with the guardian is turned on. In other words, in the default setting, the privacy level is set to the lowest and all items can be disclosed to the guardian.

[0078] The guardian can change the privacy level by pressing the button with the down arrow next to the privacy level. When the privacy level is changed, the default settings shared with the guardian of each item are displayed according to the changed privacy level. For example, when the privacy level is changed to 5, Fig.12 As shown, a screen is displayed in which the sharing of the monthly comprehensive evaluation with the guardian is turned on, and the sharing of other items with the guardian is turned off. The guardian can freely change the setting of turning on or off the sharing with the guardian for each displayed item.

[0079] When the guardian has finished changing the public range and clicked the setting completion button, Fig.14 The information of the changed public range displayed on the screen is sent to the server 30 as shown in step 106. The server 30 stores the received public range information in Figure 6 In addition, when the monitored object presses the setting end button without changing the setting of the disclosure range from the default, the CPU 41 Fig.14 The judgment is "No" in step 105, and the process proceeds to Fig.14 Step 107. Then, the default public scope is sent to the server 30.

[0080] In addition, when the subject presses Fig. 9 When the user clicks “Monthly Comprehensive Evaluation Disclosure Range Setting” at the bottom of the screen shown in FIG. 1 , the CPU 41 refers to the GUI database 48 and displays the result on the touch panel 43. Fig.11 The monthly comprehensive evaluation disclosure range setting screen 54 is shown. Similar to the previously described disclosure range initial setting screen 53, the default settings for sharing with the guardian for each item of the default privacy level, safe driving level, accelerator score, brake score, steering wheel score, vehicle distance score, and cognition and judgment score are displayed. The guardian can freely change the privacy level and the on / off of sharing with the guardian for each displayed item using the touch panel 43. And when the setting end button is pressed, the information on the disclosure range of the changed monthly comprehensive evaluation displayed on the screen will be sent to the server 30. The server 30 stores the received information on the disclosure range of the monthly comprehensive evaluation in Figure 7 The monthly comprehensive evaluation shown is in the public range database 39A.

[0081] In addition, the CPU 41 is Fig.14 If the judgment is "No" in step 101, that is, if the guardian implements the setting of the disclosure range for the second time or later, proceed to Fig.15 Step 121 of the present invention determines whether the safe driving level has been received from the server 30. The CPU 41 is Fig.15 If the judgment is "yes" in step 121, proceed to Fig.15 Step 122 of the present invention determines whether the safe driving level is 4 or above. Fig.15 If both step 121 and step 122 are judged as "yes", proceed to Fig.15 Step 123 of Fig.12 The second and subsequent settings screen 55 of the publicable range as shown in FIG. 5 is displayed. In the second and subsequent settings screen 55 of the publicable range, the profile "Daily Use for Safe Drivers" is additionally displayed in the area of ​​settings implemented according to the profile. In addition, the default privacy level is set to 5, and the default settings of sharing with guardians for the monthly comprehensive evaluation is turned on, and sharing with guardians for other items is turned off.

[0082] On the other hand, the CPU 41 is Fig.15 If the judgment is "No" in either step 121 or step 122, proceed to Fig.15 Step 124 of Fig.12 The display of the profile "Daily Use for Safe Drivers" is limited, and three profiles "Daily Use", "Long Travel", and "Night" are displayed.

[0083] When CPU 41 is Fig.15 When the configuration file is displayed in step 123 or step 124 of Fig.14 In step 103, the information of the publicable range changed by the guardian object is sent to the server 30. The server 30 stores this information in the user information database 39.

[0084] Next, in reference Fig.16 When the driving diagnosis system 100 is in operation, the vehicle terminal 20 mounted on the vehicle 10 obtains vehicle information from the plurality of vehicle-mounted devices 13 via the plurality of ECUs 11 and transmits the vehicle information to the server 30. The CPU 31 Fig.16 In step 201, the vehicle terminal 20 receives vehicle information. The vehicle information includes the speed of the vehicle 10, the yaw rate, the information of the surrounding environment of the vehicle 10, the steering angle information of the steering, the operation information of the brake, the operation information of the engine, etc. In addition, the vehicle information includes the fuel consumption rate information of the vehicle 10, the travel distance, and the travel time information.

[0085] The CPU 31 executes the diagnostic program in the processing program 35. The CPU 31 Fig.16 In step 202, the driving scene of the vehicle 10 is extracted based on the vehicle information received from the vehicle terminal 20. The driving scene includes, for example, starting, accelerating, decelerating, stopping, turning, lane changing, merging, parking, etc. The driving scene defines the period for executing the driving diagnosis.

[0086] CPU 31 Fig.16 In step 203, refer to Figure 4 The diagnostic standard database 37 shown in the figure is used to perform driving diagnosis of the driver who is the subject of supervision during the extracted driving scene. Figure 4 As shown, CPU 31 extracts the maximum acceleration, maximum deceleration, maximum lateral acceleration, inter-vehicle distance, and the presence or absence of approach warnings from the vehicle information during the driving scene. The scores of accelerator operation, brake operation, steering wheel operation, inter-vehicle distance, cognition, and judgment are calculated as diagnostic results with reference to the diagnostic standard database 37. In addition, when, for example, emergency braking is applied or when a sudden steering wheel operation is extracted, CPU 31 counts the number of times a dangerous avoidance operation is performed and sets it as a diagnostic result. Moreover, CPU 31 calculates the safe driving level of the monitored object in the driving scene based on the calculated scores and the number of dangerous avoidance operations. Then, CPU 31 Fig.16 In step 204, Fig.16 The scores of the driving operations extracted in step 204, the number of risk avoidance operations, the calculated safe driving level, the driving distance up to the extraction time of the driving scene, and the driving time are stored in the diagnosis history database 38 as diagnosis information.

[0087] CPU 31 Fig.16 In step 205, it is determined whether it is the timing to send the diagnostic information to the monitored object. Fig. 9 When the monthly comprehensive evaluation as shown is sent to the monitored object, it is a scheduled date and time at the end of the month. Fig.16 If the judgment is "yes" in step 205, proceed to Fig.16 Step 206, and send the diagnostic information to the first terminal 40 of the monitored object. Send the diagnostic information to the first terminal 40 Fig.16 The diagnostic information of all items stored in the diagnostic history database 38 and the fuel consumption information of the vehicle 10 are stored in the diagnostic history database 38.

[0088] After receiving the diagnostic information and fuel consumption information from the server 30, the first terminal 40 stores the transmitted information in the memory 42. When the monitored object starts the driving diagnostic application 46 of the first terminal 40, the CPU 41 Fig. 9 The home screen 51 shown is displayed on the touch panel 43 , and various information is read from the memory 42 and displayed on the screen.

[0089] Next, the CPU 31 executes the monitoring information extraction program included in the processing program 35. The CPU 31 Fig.16 In step 207, it is determined whether it is the timing to send the monitoring information to the guardian. The sending timing may be the same timing as the timing to send the diagnostic information to the monitored object.

[0090] The CPU 31 is Fig.16 If the judgment is "yes" in step 207, proceed to Fig.16 Step 208. Figure 6 The user information database 39 shown and Figure 7 The monthly comprehensive evaluation disclosure range database 39A shown in the figure is used to extract the diagnostic information of each item that can be disclosed to the guardian as the guardian information. For example, when the guardian object is AAA, the driving distance, driving time, and number of danger avoidance operations cannot be disclosed, and the safe driving level in the monthly comprehensive evaluation cannot be disclosed. Therefore, the CPU 31 extracts the accelerator operation score, brake operation score, steering wheel operation score, vehicle distance score, and cognition and judgment score in the monthly comprehensive evaluation as the guardian information.

[0091] Then, the CPU 31 proceeds to Fig.16 Step 209, and sending the extracted guardianship information to the guardian's second terminal 140.

[0092] The second terminal 140 of the guardian stores the information received from the server 30 in the memory 42. And, when the guardian starts the driving diagnosis application 46 of the second terminal 140, the CPU 41 Fig. 9 The home screen 51 shown is displayed on the touch panel 43, and the received monitoring information is read from the memory 42 and displayed on the screen. In the case where the guardian is aaa, the home screen 51 displays the displayed date and time, fuel efficiency information, and monthly comprehensive evaluation in addition to the safe driving level.

[0093] As described above, the driving diagnosis system 100 sets diagnostic information that can be disclosed by the monitored subject on the second terminal 140 of the guardian through the first terminal 40. The server 30 extracts items included in the disclosure range from the diagnostic information of the driving diagnosis result as monitoring information, and displays it on the second terminal 140 of the guardian. Therefore, even the monitored subject with high privacy awareness can use the driving diagnosis system 100 with confidence.

[0094] In addition, in the driving diagnosis system 100, the first terminal 40 of the monitored object displays multiple configuration files associated with multiple diagnostic items or the contents of each diagnostic item. The multiple diagnostic items or the contents of each diagnostic item associated with the configuration file selected by the monitored object are sent to the server 30 as the public range to the guardian. Then, the server 30 stores the information of the public range sent from the first terminal 40 in the user information database 39 or the monthly comprehensive evaluation public range database 39A. In addition, each configuration file is set to multiple corresponding to the use scenario of the vehicle 10. In addition, the public range is set corresponding to multiple levels of privacy.

[0095] Thus, the subject of supervision can easily send the public range to the server 30 and can easily set the public range according to the privacy level. In addition, the subject of supervision can easily set the public range according to the usage scene of the vehicle 10.

[0096] In addition, since the first terminal 40 limits the profiles that the guardian can select based on the received safe driving level, the guardian can select an appropriate profile according to the safe driving level, thereby setting the public range. In addition, when the safe driving level becomes higher, since the public range with a higher privacy level is displayed by default, the guardian will be motivated to attach importance to safe driving.

[0097] Although in the above description, the CPU 31 of the server 30 executes Fig.16 For example, the memory 22 of the vehicle-mounted terminal 20 may store the diagnostic program in the processing program 35 and the diagnostic standard database 37, and the CPU 21 may refer to the diagnostic standard database 37 to perform driving diagnosis and send the diagnostic information of the diagnosis result to the server 30. Then, the CPU 31 of the server 30 executes Fig.16 The process of step 204 to step 209. In this case, the vehicle-mounted terminal 20 and the server 30 constitute a driving diagnosis device.

[0098] In addition, in the above description, the second terminal 140 of the guardian does not implement the input of the publicly available range. Although it is set that the initial setting screen 53 of the publicly available range, the setting screen 54 of the monthly comprehensive evaluation of the publicly available range, and the setting screen 55 of the second and subsequent publicly available range are not stored, it is not limited to this. For example, the following method can also be adopted, that is, the second terminal 140 stores the initial setting screen 53 of the publicly available range, the setting screen 54 of the monthly comprehensive evaluation of the publicly available range, and the setting screen 55 of the second and subsequent publicly available range in the GUI database 48, and can implement the input of the publicly available range. Moreover, the following method can also be adopted, that is, when the guardian implements the input of the publicly available range, if the guardianship object approves the input content, the input content is stored in the user information database 39 of the server 30 and the monthly comprehensive evaluation publicly available range database 39A.

[0099] In the above description, the CPU 31 performs driving diagnosis by referring to the diagnosis standard database 37, but the present invention is not limited to this. For example, the CPU 31 may perform driving diagnosis by using a map or a function.
