Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above-cited Document 1, since the diagnosis is automatically started when the vehicle is IG-ON or the like, when the system user entrusts the inspection or repair to a maintenance shop such as a dealer, in addition to the operation by the system user, the diagnosis of operations such as an engine test by the maintenance shop is also automatically started, and since it is reflected as the diagnosis result of the system user, the system user may feel uncomfortable.

[0005] An object of the present invention is to provide an operation diagnosis system capable of managing a diagnosis result when only the system user drives.

Means for Solving the Problems

[0006] The present invention is premised on a driving diagnosis system that generates a driving diagnosis result calculated using a detected value that is a physical quantity that changes based on at least one of driving, steering, and braking of a vehicle or a physical quantity that changes when a predetermined operating member is operated. This driving diagnosis system includes a database that acquires and stores information on the detected value from the vehicle, a diagnosis unit that performs a driving diagnosis based on the information from the database, and an aggregation data transmission unit that aggregates and transmits information on the result of the diagnosis. It also includes a user interface unit that receives and stores information on the diagnosis result from the driving diagnosis device and is connectable to the Internet, and an operation unit that outputs a notification indicating that the vehicle is in a maintenance mode in response to a request from a user or a maintenance-related person of the driving diagnosis system. The driving diagnosis device belongs to a diagnosis server and executes a first determination process for determining whether the vehicle is present at or around a maintenance yard, a second determination process for determining whether the maintenance mode has been notified, and a third determination process for determining whether the person sitting in the driver's seat of the vehicle is other than the system user. When an affirmative determination is made in at least any one of the first to third determination processes, it executes any one of the driving diagnosis process, the information acquisition process, the aggregation process of the diagnosis result information, and the storage process of the diagnosis result information, or a management process for canceling the display of the diagnosis result on the display unit provided in the operation unit.

[0007] Due to this specific matter, when it is determined that it corresponds to any of the cases where the vehicle is present at or around a maintenance yard, the maintenance mode has been notified, and the person sitting in the driver's seat of the vehicle is other than the system user, since it is highly likely that the vehicle is being maintained and the system user is not driving the vehicle, it becomes possible to cancel any one of the driving diagnosis process, the information acquisition process, the aggregation process of the diagnosis result information, and the storage process of the diagnosis result information based on the driving information of a person other than the system user, that is, the driving information during vehicle maintenance, or the display of the diagnosis result on the display unit of the operation unit.

[0008] This enables the provision of useful driving diagnosis results for system users, such as being able to manage the diagnosis results when only the system user is driving.

Effects of the Invention

[0009] According to the present invention, it is possible to provide a driving diagnosis system that enables management of the diagnosis results when only the system user is driving.

Modes for Carrying Out the Invention

[0011] FIG. 1 is a diagram showing a schematic configuration of a driving diagnosis system 1, a mobile terminal 3A, and a dealer terminal 3B according to the present embodiment. These driving diagnosis system 1, vehicle 2, mobile terminal 3A, and dealer terminal 3B can perform data communication via a network. In FIG. 1, only one vehicle 2 is shown, but the driving diagnosis system 1 can receive information for driving diagnosis from a plurality of vehicles 2.

[0012] Still, the vehicle 2 provides information for driving diagnosis to the driving diagnosis system 1. The mobile terminal 3A is owned by a regular user of the vehicle 2 with an identification information (ID) attached thereto and a user of the driving diagnosis system 1 (referred to as a system user), and is, for example, a smartphone or a tablet computer. This mobile terminal 3A includes a CPU, a ROM, a RAM, a storage, a communication I / F, and an input / output I / F, and includes a display unit 31 having a touch panel, a transmission / reception unit 32, and a display control unit 33. The display unit 31 is connected to the input / output I / F of the operation terminal 3. The transmission / reception unit 32 transmits and receives information to and from the data transmission unit 64 of the UI unit 6A. The display control unit 33 causes the display unit 31 to display the information received by the transmission / reception unit 32 from the data transmission unit 64 and the information input via the touch panel (not shown) of the display unit 31. The dealer terminal 3B is provided at a maintenance shop such as a dealer, and is, for example, a tablet-type, desktop-type, or laptop-type computer. Application software for using the driving diagnosis system 1 is installed in the mobile terminal 3A and the dealer terminal 3B.

[0013] -Configuration of Vehicle- As shown in FIG. 1, the vehicle 2 includes an ECU (Electronic Control Unit) 21, a wheel speed sensor 22, an accelerator opening sensor 23, a steering angle sensor 24, a camera 25, a GPS (Global Positioning System) receiver 26, and a wireless communication device 27. A vehicle ID is assigned to the vehicle 2 as individual information of the vehicle 2. In the present embodiment, the vehicle 2 is manufactured by the main body X (automobile manufacturer). Each of the sensors 22 to 24, the camera 25, the GPS receiver 26, and the wireless communication device 27 is connected to the ECU 21. The ECU 21 includes a CPU, a ROM, a RAM, a storage, a communication I / F, and an input / output I / F that are communicably connected to each other via a bus. The network includes a communication network of a communication carrier and the Internet network. The wireless communication device 27 of the vehicle 2 enables data communication with the driving diagnosis system 1 via the network.

[0014] The wheel speed sensor 22, the accelerator opening sensor 23, the steering angle sensor 24, and the GPS receiver 26 repeatedly detect, every time a predetermined time elapses, a physical quantity that changes based on at least one of the running, steering, and braking of the vehicle 2 (such as vehicle speed, steering angle, deceleration G, etc.) or a physical quantity that changes when a predetermined operating member is operated (such as accelerator operation amount, brake operation amount, steering operation amount, etc.). Specifically, the wheel speed sensor 22 detects the rotational speed of the wheels of the vehicle 2. The accelerator opening sensor 23 detects the operation amount (accelerator opening) of the accelerator pedal. The steering angle sensor 24 detects the operation amount (steering angle) of the steering wheel. The GPS receiver 26 acquires information regarding the position where the vehicle 2 is running (hereinafter referred to as "position information") by receiving GPS signals transmitted from GPS satellites. The detection values detected by each of the sensors 22 to 24 and the GPS receiver 26 are transmitted to the ECU 21 via a CAN (Controller Area Network) provided in the vehicle 2 and stored in the storage of the ECU 21. Further, the camera 25 repeatedly images a subject located outside the vehicle 2 every time a predetermined time elapses. The image data acquired by the camera 25 is transmitted to the ECU 21 via the CAN and stored in the storage.

[0015] Detection value data, which is data representing the detection values detected by each of the sensors 22 to 24 and the GPS receiver 26, and the image data acquired by the camera 25 are transmitted from the wireless communication device 27 to the database (CAN DB) 4 via the network every time a predetermined time elapses and are recorded in the database 4. Hereinafter, these detection value data and image data may also be collectively referred to as detection values in some cases. All the detection value data and image data (detection values) recorded in the database 4 are recorded in association with information regarding the vehicle ID, information regarding the acquired time, and the position information acquired by the GPS receiver 26. Note that the detection values transmitted from the vehicle 2 to the database 4 are not limited to those described above and include various types of information that can be used for driving diagnosis. For example, it may include operation detection information of an operation lever of a direction indicator (so-called blinker), operation detection information of a shift lever, and the like.

[0016] -Configuration of the Driving Diagnosis System- The driving diagnosis system 1 has a configuration including the database 4, the diagnosis server 5, and a user interface server (hereinafter referred to as the UI server) 6. These database 4 and each server 5, 6 are arranged in one building and are connected by, for example, a LAN (Local Area Network). That is, the driving diagnosis system 1 is constructed as a cloud computing system. In this embodiment, the diagnosis server 5 is managed by the main body X. On the other hand, the UI server 6 is managed by the main body Y (system management company: for example, an automobile subscription service provider, etc.).

[0017] (Database) As described above, the database 4 receives various detection value data and image data (information for driving diagnosis) from the vehicle 2 every time a predetermined time elapses or every time a change in the physical quantity occurs, and records the various data.

[0018] Each server 5, 6 is configured to include a CPU, a ROM, a RAM, a storage, a communication I / F, and an input / output I / F.

[0019] (Diagnosis Server) An operation diagnosis device 5A is constructed inside the diagnosis server 5. That is, the operation diagnosis device 5A belongs to the diagnosis server 5. The operation diagnosis device 5A includes a diagnosis unit 51 and a summarized data transmission unit 52.

[0020] The diagnosis unit 51 includes a data reception unit 51a, a Trip generation unit 51b, a safety diagnosis unit 51c, an eco diagnosis unit 51d, a recommendation information generation unit 51e, and a diagnosis result transmission unit 51f as a functional unit realized by a control program stored in the ROM of the diagnosis server 5.

[0021] The data reception unit 51a receives various detection values (detection value data and image data) stored in the database 4 at predetermined timings. For example, it receives the data each time 1 Trip (from when the start switch of the vehicle 2 is turned ON until it is turned OFF) ends. The timing for receiving these various detection values is not limited to this.

[0022] The Trip generation unit 51b generates information (associating Trip with each data) in which various detection values for each 1 Trip of the vehicle 2 are assigned.

[0023] The safety diagnosis unit 51c diagnoses the safe driving of the vehicle 2. For example, it diagnoses each time 1 Trip of the vehicle 2 ends for information related to safety such as sudden acceleration, sudden deceleration, and sudden turning of the vehicle 2 (information related to safe driving based on the above-described physical quantities), and outputs the diagnosis results to the recommendation information generation unit 51e and the diagnosis result transmission unit 51f.

[0024] The eco diagnosis unit 51d diagnoses the eco driving of the vehicle 2 (for example, driving to reduce CO2 emissions). For example, it diagnoses each time 1 Trip of the vehicle 2 ends for information related to eco driving such as the operation amount of the accelerator pedal by the driver (information related to eco driving based on the above-described physical quantities), and outputs the diagnosis results to the recommendation information generation unit 51e and the diagnosis result transmission unit 51f.

[0025] The recommendation information generation unit 51e receives information (diagnosis result information) from the safety diagnosis unit 51c and the eco diagnosis unit 51d, and generates recommendation information according to them. For example, when receiving a diagnosis result such as a high frequency of sudden deceleration as a diagnosis result related to safe driving, or when receiving a diagnosis result such as a large operation amount of the accelerator pedal per unit time (a high frequency of sudden acceleration operation) as a diagnosis result related to eco driving, corresponding recommendation information will be generated. The generated recommendation information is output to the diagnosis result transmission unit 51f.

[0026] The diagnosis result transmission unit 51f receives the diagnosis information related to safe driving from the safe diagnosis unit 51c, the diagnosis information related to eco-driving from the eco diagnosis unit 51d, and the recommendation information from the recommendation information generation unit 51e, and transmits this information to the aggregated data transmission unit 52.

[0027] The aggregated data transmission unit 52 includes, as a functional unit realized by the control program, a data reception unit 52a, a Trip aggregation unit 52b, a Trip recommendation information generation unit 52c, a Trip score generation unit 52d, and a data transmission unit 52e.

[0028] The data reception unit 52a receives the diagnosis information related to safe driving, the diagnosis information related to eco-driving, and the recommendation information transmitted from the diagnosis result transmission unit 51f.

[0029] The Trip aggregation unit 52b aggregates the data for each Trip from each piece of information received by the data reception unit 52a.

[0030] The Trip recommendation information generation unit 52c generates recommendation information for each Trip based on the data for each Trip aggregated by the Trip aggregation unit 52b. That is, from the diagnosis information related to safe driving for each Trip, recommendation information useful for safe driving is generated as needed, and from the diagnosis information related to eco-driving for each Trip, recommendation information useful for eco-driving is generated as needed. These recommendation information are generated as information for each Trip. As an example, when it is diagnosed that a sharp steering (a situation where the change amount of the operation amount of the steering wheel per unit time is equal to or greater than a threshold value) has occurred at a speed equal to or higher than a predetermined vehicle speed as diagnosis information related to safe driving, recommendation information for proposing the installation of a system (such as a blind spot monitor system) that detects the degree of approach of other vehicles traveling in the adjacent lane and notifies the driver is generated. Also, when it is diagnosed that a situation has occurred where the switching frequency of the shift lever and the operation frequency of the steering wheel are equal to or higher than a threshold value at a vehicle speed equal to or lower than a predetermined vehicle speed, recommendation information for proposing the installation of a system (such as an advanced parking system) that automatically parks vehicle 2 in a parking space is generated.

[0031] The Trip score generation unit 52d generates an index (score) for driving evaluation based on the diagnosis information related to safe driving for each Trip and the diagnosis information related to eco-driving for each Trip. For example, a five-level evaluation is performed as an evaluation related to safe driving and eco-driving, and evaluation information for safe driving and eco-driving for each Trip is generated. As this evaluation information, the higher the frequency of driving operations leading to safe driving (driving operations that do not cause sudden acceleration, sudden deceleration, or sudden turning), and the higher the frequency of driving operations leading to eco-driving (driving operations that can reduce CO2 emissions), the higher the score will be generated.

[0032] The data transmission unit 52e transmits each information received from the diagnosis unit 51 (including the diagnosis result information of the safety diagnosis unit 51c, the diagnosis result information of the eco-diagnosis unit 51d, and the recommendation information of the recommendation information generation unit 51e), the recommendation information for each Trip, and the score information for each Trip to the UI server 6.

[0033] (UI Server) Inside the UI server 6, a UI section 6A is constructed. That is, the UI section 6A belongs to the UI server 6. The UI section 6A includes a monthly recommendation diagnosis section 61, a monthly recommendation aggregation section 62, a result storage section 63, and a data transmission section 64 as functional sections realized by a control program stored in the ROM of the UI server 6. Also, the accounts of the system users set in this UI server 6 are separate from the accounts set in the diagnosis server 5. That is, the accounts of the system users in the driving diagnosis system 1 according to this embodiment are set individually for each of the servers 5 and 6.

[0034] The monthly recommendation diagnosis section 61 receives the recommendation information for each Trip and the information on the score for each Trip from the aggregated data transmission section 52 at predetermined timings, and performs a diagnosis regarding the recommendations for these information over a one - month period. For example, it accumulates each information from the 1st day of each month and performs a diagnosis regarding the recommendations based on each information received by the end of the current month. Therefore, this monthly recommendation diagnosis section 61 corresponds to the second diagnosis section (the second diagnosis section that performs a diagnosis regarding the recommendations over a certain period) in the present invention.

[0035] The monthly recommendation aggregation section 62 aggregates the diagnosis information calculated by the monthly recommendation diagnosis section 61 and calculates, for example, the ratio for each type of diagnosis result. For example, in the diagnosis regarding safe driving, it calculates the ratio of the number of occurrences of rapid acceleration, rapid deceleration, and rapid turning of the vehicle 2, etc. The information on the monthly recommendation generated in this monthly recommendation aggregation section 62 is also generated as recommendation information useful for safe driving and eco - driving as needed from the diagnosis information (information over a one - month period), similar to the information on the Trip recommendation generated by the Trip recommendation information generation section 52c described above.

[0036] The result storage unit 63 stores each piece of information from the aggregation data transmission unit 52 (including the diagnostic result information of the safety diagnosis unit 51c, the diagnostic result information of the eco-diagnosis unit 51d, and the recommendation information of the recommendation information generation unit 51e) and the diagnostic information aggregated by the monthly recommendation aggregation unit 62. These pieces of information are stored in the result storage unit 63 for a predetermined period. Also, each piece of information stored in this result storage unit 63 may be deleted from the result storage unit 63 by an operation of the mobile terminal 3A by a user of the system (hereinafter referred to as the system user), or may be deleted by the entity Y.

[0037] The data transmission unit 64 can transmit and receive various pieces of information to and from the mobile terminal 3A and the dealer terminal 3B through the Internet.

[0038] The data transmission unit 64 extracts information corresponding to a request from among these pieces of information in response to a request from the mobile terminal 3A for various pieces of information (such as monthly recommendation information and each diagnostic result information) stored in the result storage unit 63 and transmits it to the mobile terminal 3A. Also, a Push notification may be sent to the mobile terminal 3A at the timing when the monthly recommendation information is generated. Note that the aggregation data transmission unit 52 and the second aggregation data transmission unit (the monthly recommendation aggregation unit 62, the result storage unit 63, and the data transmission unit 64) correspond to the "aggregation data transmission unit" described in the claims.

[0039] As described above, the UI server 6 in this embodiment handles information related to monthly recommendations. There may be cases where it is preferable to update thresholds and logics for diagnosis from the statistical data of system users. There may also be cases where it is preferable to change for marketing reasons. The frequency of updating these thresholds and logics is higher compared to those with relatively fixed thresholds such as sudden acceleration and sudden deceleration. In view of this point, in this embodiment, the operation diagnosis system 1 is constructed such that the server that handles information with a high update frequency is the UI server 6. That is, by implementing the processing of information with a relatively high update frequency in the UI unit 6A belonging to the UI server 6, the update processing of the entire system can be accelerated compared to the case where the processing of this information is performed in the operation diagnosis device 5A.

[0040] In addition, in this embodiment, since the UI server 6 is configured to handle information related to monthly recommendations, the diagnosis server 5, rather than the UI server 6, handles information related to Trip recommendations. Therefore, when transmitting diagnosis information and recommendation information for each Trip to the mobile terminal 3A, the information created in the diagnosis server 5 is temporarily stored in the result storage unit 63 of the UI server 6 and transmitted to the mobile terminal 3A in response to a request from the mobile terminal 3A.

[0041] - Information transmission and reception operation - Next, the information transmission and reception operation by the operation diagnosis system 1 according to this embodiment will be described with reference to the sequence diagram in FIG. 2. This sequence diagram shows the transmission and reception of information among the vehicle 2, the database (CAN DB) 4, the diagnosis unit 51, the aggregated data transmission unit 52, the UI unit 6A, the mobile terminal 3A, and the dealer terminal 3B.

[0042] First, vehicle data (detection value data and image data) is transmitted from vehicle 2 to database 4 at predetermined timings (communication operation A in FIG. 2). After the vehicle data is accumulated in database 4 for a certain period, it is transmitted to diagnosis unit 51 every time a predetermined timing, for example, the end of 1 Trip, is reached (communication operation B in FIG. 2). Diagnosis unit 51 performs driving diagnosis (processing of Trip generation unit 51b, safety diagnosis unit 51c, eco diagnosis unit 51d, and recommendation information generation unit 51e) every time the end of 1 Trip of vehicle 2 is reached based on the information from database 4. Information on the diagnosis result of this driving is transmitted to aggregation data transmission unit 52 (communication operation C in FIG. 2). Aggregation data transmission unit 52 performs processing such as aggregating the received diagnosis result information (processing in Trip aggregation unit 52b, Trip recommendation information generation unit 52c, and Trip score generation unit 52d), and then this aggregation result is transmitted to UI unit 6A (communication operation D in FIG. 2).

[0043] UI unit 6A performs processing for accumulating the received aggregation result (accumulation processing for one month), and then performs the diagnosis processing of monthly recommendation diagnosis unit 61 and the aggregation processing of monthly recommendation aggregation unit 62. As a result, information on the diagnosis result of safety diagnosis unit 51c, information on the diagnosis result of eco diagnosis unit 51d, recommendation information of recommendation information generation unit 51e, monthly recommendation information, etc. are stored in result storage unit 63.

[0044] Then, when the system user operates the mobile terminal 3A to start the application software pre-installed on the mobile terminal 3A and performs a data transmission request operation on the application software, the request information is transmitted to the UI unit 6A (communication operation E in FIG. 2). In response, the UI unit 6A creates UI data for transmission (monthly recommendation information for transmission, etc.) and transmits the UI data to the mobile terminal 3A (communication operation F in FIG. 2: the process of obtaining necessary information from the aggregation result and providing it to the system user as defined in the present invention). As a result, the system user can view the evaluation result of vehicle driving in one month and the recommendation information regarding the recommended system upgrade on the display screen of the mobile terminal 3A. Also, the system user can confirm the diagnosis information and recommendation information for each Trip by operating the mobile terminal 3A.

[0045] Furthermore, when the system user entrusts the vehicle 2 to a maintenance yard for maintenance inspection, repair, etc., a situation arises where a maintenance-related person other than the system user drives the vehicle 2. Such a situation is referred to as the "maintenance mode". The mobile terminal 3A is configured to be able to perform an operation for notifying the driving diagnosis device 5A that the vehicle 2 is in the maintenance mode by the system user. Also, the dealer terminal 3B is configured to be able to perform an operation for notifying the driving diagnosis device 5A that the vehicle 2 is in the maintenance mode by the maintenance-related person. That is, the mobile terminal 3A and the dealer terminal 3B correspond to the operation unit described in the claims. When the driving diagnosis device 5A receives a notification that it is in the maintenance mode from the mobile terminal 3A or the dealer terminal 3B via the UI unit 6A, it recognizes that the vehicle 2 is in the maintenance mode and cancels the diagnosis of the vehicle 2 by the diagnosis unit 51.

[0046] Specifically, FIG. 3 is a flowchart for explaining each process related to the diagnosis by the driving diagnosis device 5A in the present embodiment.

[0047] First, in step S1, it is determined whether the vehicle 2 is present at or around the maintenance yard. In this step S1, if the determination is affirmative, the diagnosis of the operation of the vehicle 2 is canceled in step S5, while if the determination is negative, the process proceeds to step S2.

[0048] In step S2, it is determined whether the maintenance mode is notified. In this step S2, if the determination is affirmative, the diagnosis of the operation of the vehicle 2 is canceled in step S5, while if the determination is negative, the process proceeds to step S3.

[0049] In step S3, it is determined whether the person sitting in the driver's seat of the vehicle 2 is other than the system user. This determination can be made indirectly, for example, by examining whether the driving tendency (the tendency of each score of the driving diagnosis) is different from normal based on the driving information, or directly by examining whether the person sitting in the driver's seat of the vehicle 2 is other than the system user based on the image information of the driver's seat taken by an in-vehicle camera (not shown). In this step S3, if the determination is affirmative, the diagnosis of the operation of the vehicle 2 is canceled in step S5, while if the determination is negative, the diagnosis of the vehicle 2 is executed in step S4.

[0050] In such a flowchart of FIG. 3, step S1 corresponds to the "first determination process" described in the claims, step S2 corresponds to the "second determination process" described in the claims, step S3 corresponds to the "third determination process" described in the claims, step S4 corresponds to the "diagnosis process" described in the claims, and step S5 corresponds to the "management process" described in the claims, respectively.

[0051] - Effects of the Embodiment - As described above, in the present embodiment, when the vehicle 2 is present at or around the maintenance yard, when the maintenance mode is notified, and when the person sitting in the driver's seat of the vehicle 2 is other than the system user, if it is determined that any of these conditions is met, since the vehicle 2 is under maintenance and it is highly likely that the system user is not driving the vehicle 2, it becomes possible to cancel the diagnosis of driving based on the driving information of someone other than the system user, that is, the driving information during the maintenance of the vehicle 2.

[0052] That is, since it becomes possible to cancel the driving diagnosis based on the information when someone other than the system user is driving, it becomes possible to manage the diagnosis results when only the system user is driving, etc., and it becomes possible to provide useful driving diagnosis results for the system user.

[0053] -Other Embodiments- Note that the present invention is not limited to the above-described embodiment, and all modifications and applications included in the scope of the claims and the scope equivalent thereto are possible.

[0054] (1) For example, the diagnostic items to be placed in the UI unit 6A may be, for example, the user's own ranking (such as the ranking in safe driving) among a plurality of users using the driving diagnosis system 1, the results of diagnoses based on statistics such as deviation values, or map information. That is, it may be a diagnostic result or the like combined with information other than the information obtained only from one vehicle 2 used by the user.

[0055] (2) The information on the diagnostic results and the recommendation information may be made available for confirmation not only on the mobile terminal 3A but also on a web page.

[0056] (3) In the above embodiment, an example of notifying the maintenance mode by the mobile terminal 3A and the dealer terminal 3B is given, but the present invention is not limited to this alone. For example, making it impossible for the dealer terminal 3B to notify the maintenance mode is also included in the present invention.

[0057] (4) In the above-described embodiment, an example is given in which a notification of the maintenance mode from the mobile terminal 3A and the dealer terminal 3B is input to the diagnostic unit 51 of the driving diagnostic device 5A via the UI unit 6. However, the present invention is not limited to this alone.

[0058] For example, it is possible to configure the notification of the maintenance mode from the mobile terminal 3A and the dealer terminal 3B to be directly input to the diagnostic unit 51 of the driving diagnostic device 5A.

[0059] (5) In the above-described embodiment, an example is given in which when an affirmative determination is made by at least any one of steps S1 to S3 in FIG. 3, the diagnosis of driving by the diagnostic unit 51 is canceled. However, the present invention is not limited to this alone.

[0060] For example, when an affirmative determination is made by at least any one of steps S1 to S3 in FIG. 3, it is possible to configure the display of the diagnosis result of driving on the display unit 31 of the mobile terminal 3A to be canceled. As a result, it is possible to cancel the display of the driving diagnosis result on the display unit 31 of the mobile terminal 3A owned by the system user. As a result, it is possible to avoid the diagnosis result displayed on the mobile terminal 3A from causing a sense of discomfort to the system user.

[0061] Further, when an affirmative determination is made by at least any one of steps S1 to S3 in FIG. 3, it is possible to cancel any one of the information acquisition process of the database 4, the aggregation process of the aggregation data transmission units (52, 62 to 64), and the accumulation process of the UI unit 6A.

[0062] Incidentally, when canceling the information acquisition process of the database 4, since it is not necessary to execute each process after the information acquisition process, it is possible to reduce the load of information processing. Also, when canceling the accumulation process of the UI unit 6A, it is possible to restore the information acquired in the information acquisition process of the database 4 or the aggregation information in the aggregation process by the aggregation data transmission units (52, 62 to 64) if the cancellation is incorrect.

[0063] (6) In the above-described embodiment, when the vehicle 2 is present at or around the maintenance yard (step S2 in FIG. 3), when the maintenance mode is notified (step S3 in FIG. 3), and when the person sitting in the driver's seat of the vehicle 2 is other than the system user (step S4 in FIG. 3), an example is given in which the driving diagnosis is canceled when it is determined that any of these conditions is met. However, the present invention is not limited to this alone.

[0064] For example, the present invention also includes a form having only any one or two of steps S1 to S3 in FIG. 3.
