Embodiments for Carrying Out the Invention

[0027] Hereinafter, embodiments of the driving diagnosis device, driving diagnosis system (hereinafter referred to as the system), driving diagnosis method, and program according to the present invention will be described with reference to the accompanying drawings.

[0028] As shown in FIG. 1, the system 10 of the present embodiment includes a vehicle 20, an external server (computer) (first driving diagnosis unit) (specific driving diagnosis unit) 30, a mobile terminal 40, and a server 50.

[0029] The vehicle 20 capable of data communication with the external server 30, the mobile terminal 40, and the server 50 via a network includes, as shown in FIG. 1, an ECU (Electronic Control Unit) (second driving diagnosis unit) (driving diagnosis device) 21, a wheel speed sensor 22, an accelerator opening sensor 23, a brake pedal force sensor 24, a steering angle sensor 25, a front camera 26A, an in-vehicle camera 26B, a GPS (Global Positioning System) receiver 27, and a display 28. The wheel speed sensor 22, the accelerator opening sensor 23, the brake pedal force sensor 24, the steering angle sensor 25, the front camera 26A, the in-vehicle camera 26B, the GPS receiver 27, and the display 28 are connected to the ECU 21. In the following description, the wheel speed sensor 22, the accelerator opening sensor 23, the brake pedal force sensor 24, the steering angle sensor 25, the front camera 26A, the in-vehicle camera 26B, and the GPS receiver 27 may be collectively referred to as an "information acquisition unit".

[0030] The vehicle 20 is provided with four wheel speed sensors 22. Each wheel speed sensor 22 detects the wheel speeds of the four wheels respectively. The accelerator opening sensor 23 detects the accelerator opening. The brake pedal force sensor 24 detects the brake pedal force input by the driver Dr to a brake pedal (not shown). The steering angle sensor 25 detects the steering angle of a steering wheel (not shown). The front camera 26A acquires out-of-vehicle image data, which is image data of the scenery in front of the vehicle 20. The in-vehicle camera 26B acquires face image data, which is image data of the face of the driver Dr sitting in the driver's seat (not shown) of the vehicle 20. The GPS receiver 27 acquires information regarding the position where the vehicle 20 is traveling (hereinafter referred to as "position data") by receiving GPS signals transmitted from GPS satellites. The acquisition data acquired by the information acquisition unit every time a predetermined time elapses is transmitted to the ECU 21 via an in-vehicle network provided in the vehicle 20 and stored in a storage 21D of the ECU 21 described later while being associated with time information. Note that this in-vehicle network is, for example, a CAN (Controller Area Network). In the following description, the acquisition data acquired by the information acquisition unit may be referred to as "vehicle-related information". Further, the information acquisition unit of the present embodiment acquires each acquisition data at a first frequency that is a frequency equal to or higher than a first threshold value. The first threshold value is, for example, 1 / 100 second.

[0031] The display 28 provided on the instrument panel (not shown) of the vehicle 20 can display various images.

[0032] As shown in FIG. 2, the ECU (computer) 21 includes a CPU (Central Processing Unit) 21A, a ROM (Read Only Memory) 21B, a RAM (Random Access Memory) 21C, a storage 21D, a communication I / F (Inter Face) (transmission unit) 21E, and an input / output I / F 21F. The CPU 21A, the ROM 21B, the RAM 21C, the storage 21D, the communication I / F 21E, and the input / output I / F 21F are communicably connected to each other via a bus 21Z. The CPU 21A can acquire information regarding the date and time from a timer (not shown).

[0033] The CPU 21A is a central processing unit that executes various programs and controls each part. That is, the CPU 21A reads a program from the ROM 21B or the storage 21D and executes the program using the RAM 21C as a working area. The CPU 21A performs control of each component and various arithmetic processes (information processing) according to the program recorded in the ROM 21B or the storage 21D.

[0034] The ROM 21B stores various programs and various data. The RAM 21C temporarily stores a program or data as a working area. The storage 21D is composed of a storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive) and stores various programs and various data.

[0035] The communication I / F 21E is an interface for communicating with various devices. For example, the communication I / F 21E can communicate with a device other than the ECU 21 provided in the vehicle 20 via the in-vehicle network. These devices include, for example, an information acquisition unit. Further, the communication I / F 21E can wirelessly communicate with an external server 30, a mobile terminal 40, and a server 50 via a network (for example, the Internet).

[0036] FIG. 3 shows an example of the functional configuration of the ECU 21 in a block diagram. The ECU 21 includes, as functional components, a PCS control unit 201, a wakefulness estimation unit 202, a data classification unit 203, a diagnostic unit 204, a display control unit 205, and a communication control unit 206. These functional components are realized by the CPU 21A reading and executing a program stored in the ROM 21B.

[0037] The PCS control unit 201 has a function of controlling the PCS (Pre Crash Safety system) mounted on the vehicle 20. That is, when a predetermined condition is satisfied, the PCS control unit 201 controls the brake actuator of the brake device (not shown) of the vehicle 20 to generate a braking force in the brake device.

[0038] The wakefulness estimation unit 202 determines the wakefulness of the driver Dr based on the state of the eyes etc. of the driver Dr included in the face image data captured by the in-vehicle camera 26B. The "wakefulness" in this specification includes the wakefulness level when a person is awake and the sleep level (sleep depth) when a person is in a sleeping state. The sleep level (sleep depth) is defined in five levels. The larger the number of the sleep level (sleep depth), the deeper the sleep of the driver Dr. The wakefulness estimation unit 202 determines that the driver Dr is drowsy driving when the sleep level is equal to or higher than a predetermined level. An example of the predetermined level is sleep level 1.

[0039] The data classification unit 203 classifies the vehicle-related information recorded in the storage 21D based on the data classification list 29 shown in FIG. 4. The data classification list 29 classifies the vehicle-related information into three attributes. That is, the data classification list 29 defines first data, second data, and third data as the attributes of the vehicle-related information. These attributes are set based on each driving diagnosis mode described later. More specifically, these attributes are set based on at least one of the type of the output destination of the result information representing the result of the driving diagnosis, the type of the result information, and the type of the vehicle-related information. Here, the output destination of the result information refers to the display subject of the result information. For example, the display 28 of the vehicle 20 and the display 41 of the mobile terminal 40 correspond to the output destinations of the result information. The types of the result information include real-time driving diagnosis (second driving diagnosis), normal driving diagnosis (first driving diagnosis), and insurance driving diagnosis (first driving diagnosis) described later. Furthermore, the data classification list 29 defines the transmission destination of the vehicle-related information. This transmission destination refers to the subject of the driving diagnosis using the vehicle-related information.

[0040] The first data is vehicle-related information used by the diagnosis unit 204 to execute the real-time driving diagnosis described later. The second data is vehicle-related information used by the external server 30 to execute the normal driving diagnosis described later. The third data is vehicle-related information used by the external server 30 to execute the insurance driving diagnosis described later. As is clear from FIG. 4, some of the vehicle-related information has multiple attributes.

[0041] The content of the data classification list 29 can be changed using the touch panel (information input unit) provided on the display 28. Also, when predetermined information is input to the input device connected to the external server 30, this information is wirelessly transmitted from the external server 30 to the vehicle 20, and based on this information, the content of the data classification list 29 is changed. That is, the content of the data classification list 29 can be changed, for example, by the administrator of the external server 30 or the driver Dr.

[0042] The diagnostic unit 204 performs a driving diagnosis based on the acquired data from the wheel speed sensor 22, the accelerator opening sensor 23, and the brake pedal force sensor 24. For example, as disclosed in Japanese Patent Application Laid-Open No. 2019-12481 and Japanese Patent Application Laid-Open No. 2020-95403, the method of driving diagnosis performed based on these acquired data is well-known. The diagnostic unit 204 determines whether the vehicle speed of the vehicle 20 exceeds the speed limit based on the information on the speed limit of each road included in the map data recorded in the storage 21D, the position data of the vehicle 20, and the acquired data of the wheel speed sensor 22. The result information regarding the violation of the speed limit may be referred to as speed limit violation data.

[0043] Furthermore, the diagnostic unit 204 determines whether the vehicle 20 has performed a sudden acceleration operation based on the acquired data of the accelerator opening sensor 23 and the acquired data of the wheel speed sensor 22. Furthermore, the diagnostic unit 204 determines whether the vehicle 20 has performed a sudden braking operation based on the acquired data of the brake pedal force sensor 24 and the acquired data of the wheel speed sensor 22.

[0044] When the PCS control unit 201 activates the PCS, the diagnostic unit 204 generates PCS activation data indicating this. Furthermore, when the wakefulness estimation unit 202 determines that the driver Dr is dozing off while driving, the diagnostic unit 204 generates dozing determination data indicating this.

[0045] The result information of the driving diagnosis based on the acquired data of the wheel speed sensor 22, the accelerator opening sensor 23, and the brake pedal force sensor 24, the PCS activation data, and the dozing determination data are the result information of the real-time driving diagnosis. Note that these result information are recorded in the storage 21D together with the position data and the time information.

[0046] Note that the diagnostic unit 204 executes a real-time driving diagnosis based on the acquired data of the wheel speed sensor 22, the accelerator opening sensor 23, and the brake pedal force sensor 24 acquired at the above first frequency. Therefore, the diagnostic accuracy of the speed limit diagnosis, sudden acceleration diagnosis, and sudden braking diagnosis by the diagnostic unit 204 is higher than that based on the acquired data acquired at a frequency lower than the first frequency.

[0047] The display control unit 205 controls the display 28. The display 28 controlled by the display control unit 205 displays, for example, the result information of real-time operation diagnosis on the display 28 for a certain period of time immediately after the diagnosis operation of the diagnosis unit 204. This certain period of time is, for example, 5 seconds. For example, when the diagnosis unit 204 generates drowsiness determination data, as shown in FIG. 5, a video (not shown) of the face of the driver Dr acquired by the in-vehicle camera 26B when it is determined that the driver is drowsy is displayed on the display 28 together with the characters "Drowsiness Warning!"

[0048] Also, when the diagnosis unit 204 generates PCS operation data, a video (hereinafter referred to as an out-of-vehicle video. Not shown) acquired by the front camera 26A when the PCS operates is displayed on the display 28 together with the characters "PCS Operation".

[0049] Furthermore, when the diagnosis unit 204 determines that the vehicle speed of the vehicle 20 has exceeded the speed limit, an out-of-vehicle video when the speed limit is exceeded is displayed on the display 28 together with the characters "Speed Limit Violation". Furthermore, when the diagnosis unit 204 determines that "the vehicle 20 has performed a rapid acceleration operation", an out-of-vehicle video when the rapid acceleration operation is executed is displayed on the display 28 together with the characters "Rapid Acceleration". Also, when the diagnosis unit 204 determines that "the vehicle 20 has performed a rapid braking operation", an out-of-vehicle video when the rapid braking operation is executed is displayed on the display 28 together with the characters "Rapid Braking".

[0050] The communication control unit 206 controls the communication I / F 21E. The communication I / F 21E controlled by the communication control unit 206 wirelessly transmits vehicle-related information corresponding to the second data and the third data recorded in the storage 21D, as well as drowsiness determination data, speed limit violation data, and PCS operation data to the external server 30 every time a predetermined data recording time elapses. That is, the communication I / F 21E collectively wirelessly transmits the data for the data recording time recorded in the storage 21D to the external server 30. This data recording time is, for example, 10 minutes. However, the communication I / F 21E of the present embodiment wirelessly transmits the second data and the third data recorded in the storage 21D while thinning them out. That is, the second data and the third data transmitted wirelessly by the communication I / F 21E are acquisition data acquired by the information acquisition unit at a second frequency that is a frequency equal to or lower than the second threshold value. This second threshold value is a value smaller than the first threshold value and is, for example, 1 / 10 second. Therefore, the data volume of the vehicle-related information transmitted wirelessly by the communication I / F 21E to the external server 30 is smaller than when it is not thinned out.

[0051] As shown in FIG. 2, the external server 30 includes a CPU 31A, a ROM 31B, a RAM 31C, a storage 31D, a communication I / F 31E, and an input / output I / F 31F. The CPU 31A, the ROM 31B, the RAM 31C, the storage 31D, the communication I / F 31E, and the input / output I / F 31F are connected to be communicable with each other via a bus 31Z. The CPU 31A, the ROM 31B, the RAM 31C, the storage 31D, the communication I / F 31E, and the input / output I / F 31F have functions corresponding to those of the CPU 21A, the ROM 21B, the RAM 21C, the storage 21D, the communication I / F 21E, and the input / output I / F 21F, respectively. However, the computing power of the CPU 31A is higher than that of the CPU 21A. Note that map data is recorded in the storage 31D.

[0052] Furthermore, the external server 30 has received authentication from the insurance company that manages the server 50. That is, this insurance company has determined that the result information of the normal operation diagnosis executed by the external server 30 can be used by the insurance company for the design of insurance products. In other words, the insurance company has determined that the processing capacity and security level of the external server 30 meet the required requirements.

[0053] FIG. 6 shows an example of the functional configuration of the external server 30 in a block diagram. The external server 30 includes a diagnosis unit 301 and a communication control unit 302 as its functional configuration. These functional configurations are realized by the CPU 31A reading and executing the program stored in the ROM 31B.

[0054] The diagnosis unit 301 performs a normal operation diagnosis, which is a type of driving diagnosis, based on the second data received by the communication I / F 31E from the vehicle 20. Note that, as will be described later, the diagnosis content of the driving diagnosis for insurance purposes is included in the diagnosis content of the normal operation diagnosis. Therefore, the third data in this embodiment is the second data. The diagnosis unit 301 performs the normal operation diagnosis while executing machine learning. That is, the diagnosis unit 301 diagnoses the driving operation of the driver Dr based on the vehicle-related information acquired over a long period from the vehicle 20 driven by the driver Dr and the result information of the normal operation diagnosis of a large number of drivers other than the driver Dr. However, the method of the normal operation diagnosis in the present invention is not limited to this and may be any method.

[0055] The normal driving diagnosis performed by the diagnosis unit 301 includes driving diagnoses related to accelerator operation, brake operation, and steering operation. The diagnosis unit 301 performs a driving diagnosis on the accelerator operation based on the acquired data of the accelerator opening sensor 23 and the acquired data of the wheel speed sensor 22, performs a driving diagnosis on the brake operation based on the acquired data of the brake pedal force sensor 24 and the acquired data of the wheel speed sensor 22, and performs a driving diagnosis on the steering operation based on the acquired data of the steering angle sensor 25. These diagnosis results include information representing the driving operation tendency of the driver Dr obtained based on machine learning. Further, the diagnosis unit 301 calculates scores for the accelerator operation, brake operation, and steering operation based on these diagnosis results (see FIG. 11).

[0056] Furthermore, the normal driving diagnosis executed by the diagnosis unit 301 includes drowsiness determination data, speed limit violation data, and PCS activation data received by the external server 30 from the vehicle 20. That is, the diagnosis unit 301 adds the drowsiness determination data, speed limit violation data, and PCS activation data to the driving diagnosis based on the accelerator operation, brake operation, and steering operation, thereby generating the result information 40F of the normal driving diagnosis (see FIG. 11).

[0057] The diagnosis unit 301 executes the driving diagnosis for insurance by removing the drowsiness determination data, speed limit violation data, and PCS activation data from the normal driving diagnosis. That is, the result information (specific result information) of the driving diagnosis for insurance includes only the results of the driving diagnosis executed by the external server 30 authenticated by the insurance company. That is, the result information of the driving diagnosis for insurance does not include the result information of the real-time driving diagnosis generated by the ECU 21 not authenticated by the insurance company. The result information of the normal driving diagnosis and the driving diagnosis for insurance is recorded in the storage 31D.

[0058] The communication control unit 302 controls the communication I / F 31E. Data including vehicle-related information, drowsiness determination data, speeding violation data, and PCS operation data received by the communication I / F 31E from the vehicle 20 is recorded in the storage 31D. The communication I / F 31E transmits the result information of the normal driving diagnosis recorded in the storage 31D to the mobile terminal 40. Further, the communication I / F 31E transmits the result information of the driving diagnosis for insurance recorded in the storage 31D to the server 50.

[0059] The server 50 has the same hardware configuration as the external server 30. Therefore, the result information of the driving diagnosis for insurance received by the communication I / F of the server 50 is recorded in the storage of the server 50.

[0060] The mobile terminal 40 shown in FIG. 1 includes a CPU, ROM, RAM, storage, communication I / F, and input / output I / F. The mobile terminal 40 is, for example, a smartphone or a tablet computer. The CPU, ROM, RAM, storage, communication I / F, and input / output I / F of the mobile terminal 40 are communicably connected to each other via a bus. The mobile terminal 40 can acquire information regarding the date and time from a timer (not shown). The mobile terminal 40 is provided with a display 41 having a touch panel. As shown in FIG. 1, the mobile terminal 40 is owned by the driver Dr. A predetermined driving information display application is installed in the mobile terminal 40. Further, map data is recorded in the storage of the mobile terminal 40.

[0061] FIG. 7 shows an example of the functional configuration of the mobile terminal 40 in a block diagram. The mobile terminal 40 includes, as functional components, a communication control unit 401 and a display control unit 402. The communication control unit 401 and the display control unit 402 are realized by the CPU reading and executing a program stored in the ROM.

[0062] The communication control unit 401 controls the communication I / F.

[0063] The display control unit 402 controls the display 41. That is, the display control unit 402 causes the display 41 to display, for example, the information received by the mobile terminal 40 from the vehicle 20 or the external server 30 and the information input via the touch panel. The information input by the touch panel of the display 41 can be transmitted, for example, by the communication I / F to the vehicle 20 and the external server 30.

[0064] (Operations and effects) Next, the operations and effects of the present embodiment will be described.

[0065] First, the flow of the process performed by the CPU 21A of the vehicle 20 will be described with reference to the flowchart of FIG. 8. The CPU 21A repeatedly executes the process of the flowchart of FIG. 8 every time a predetermined time elapses. In the following description, each process of the flowcharts in FIGS. 8 to 10 is executed by one processor (CPU), but a plurality of processors (CPUs) may execute each process of the flowcharts in FIGS. 8 to 10.

[0066] In step S10 (hereinafter, the character "step" is omitted), the CPU 21A determines whether or not it has acquired at least one of vehicle-related information, PCS operation data, and drowsiness determination data.

[0067] When it is determined Yes in S10, the CPU 21A proceeds to S11 and records the acquired information (data) in the storage 21D.

[0068] Subsequently, the CPU 21A proceeds to S12 and determines whether or not the first data is included in the vehicle-related information recorded in the storage 21D.

[0069] When it is determined Yes in S12, the CPU 21A proceeds to S13 and determines whether or not a sufficient amount of the first data for executing the real-time driving diagnosis is recorded in the storage 21D.

[0070] When it is determined Yes in S13, the CPU 21A proceeds to S14 and executes the real-time driving diagnosis.

[0071] Subsequently, the CPU 21A proceeds to S15 and causes the result information of the real-time operation diagnosis to be displayed on the display 28.

[0072] When it is determined as No in S10, 12, or 13, or when the process of S15 is completed, the CPU 21A proceeds to S16 and determines whether the data recording time has elapsed. The CPU 21A repeatedly executes the process of S16 until it determines Yes.

[0073] When it is determined as Yes in S16, the CPU 21A proceeds to S17 and wirelessly transmits the second data (third data), drowsiness determination data, speed limit violation data, and PCS operation data included in the vehicle-related information recorded in the storage 21D during the data recording time to the external server 30.

[0074] When the process of S17 is completed, the CPU 21A temporarily ends the process of the flowchart in FIG. 8.

[0075] Next, the flow of the process performed by the CPU 31A of the external server 30 will be described using the flowchart in FIG. 9. The CPU 31A repeatedly executes the process of the flowchart in FIG. 9 every time a predetermined time elapses.

[0076] First, in S20, the CPU 31A determines whether it has received at least one of vehicle-related information (second data, third data), drowsiness determination data, speed limit violation data, and PCS operation data from the vehicle 20.

[0077] When it is determined as Yes in S20, the CPU 31A proceeds to S21 and determines whether a sufficient amount of the second data is recorded in the storage 21D to execute the normal operation diagnosis. Note that the amount of data required to determine Yes in S21 is much larger than the amount of data required to determine Yes in S13. That is, the normal operation diagnosis is executed using more data than the real-time operation diagnosis.

[0078] When it is determined as Yes in S21, the CPU 31A proceeds to S22 and executes normal operation diagnosis.

[0079] Subsequently, the CPU 31A proceeds to S23 and records the result information of the normal operation diagnosis in the storage 21D.

[0080] Subsequently, the CPU 31A proceeds to S24 and determines whether a transmission request has been received from the mobile terminal 40. When the operation information display application of the mobile terminal 40 is activated, the mobile terminal 40 wirelessly transmits a transmission request to the external server 30 every time a predetermined time elapses.

[0081] When it is determined as Yes in S24, the CPU 31A proceeds to S25 and wirelessly transmits the result information of the normal operation diagnosis to the mobile terminal 40.

[0082] Subsequently, the CPU 31A proceeds to S26 and executes insurance operation diagnosis based on the result information of the normal operation diagnosis.

[0083] Subsequently, the CPU 31A proceeds to S27, records the result information of the insurance operation diagnosis in the storage 21D, and wirelessly transmits it to the server 50.

[0084] When it is determined as No in S20 or S21, or when the process of S27 is completed, the CPU 31A temporarily ends the process of the flowchart in FIG. 9.

[0085] Next, the flow of the process performed by the CPU of the mobile terminal 40 will be described using the flowchart in FIG. 10. The CPU repeatedly executes the process of the flowchart in FIG. 10 every time a predetermined time elapses.

[0086] First, in S30, the CPU determines whether the operation information display application is activated.

[0087] When it is determined as Yes in S30, the CPU proceeds to S31 and wirelessly transmits a transmission request to the external server 30.

[0088] Subsequently, the CPU proceeds to S32 and determines whether it has received the result information of the normal operation diagnosis from the external server 30.

[0089] When it is determined as Yes in S32, the CPU proceeds to S33 and causes the display 41 to display the result information 40F (see FIG. 11).

[0090] When the process of S33 is completed, or when it is determined as No in S30 or S32, the CPU temporarily ends the process of the flowchart in FIG. 10.

[0091] As described above, in the system 10 of the present embodiment, the vehicle-related information acquired by the information acquisition unit is transmitted to at least one of the ECU 21 and the external server 30 based on each driving diagnosis mode. In other words, the transmission destination of the vehicle-related information is determined based on at least one of the type of the output destination of the driving diagnosis result information, the type of the driving diagnosis (type of the result information), and the type of the vehicle-related information.

[0092] For example, the vehicle-related information (first data) for executing the real-time driving diagnosis whose output destination is the display 28 is transmitted to the ECU 21. Therefore, the ECU 21 can quickly display the result information of the real-time driving diagnosis on the display 28. That is, for example, compared with the case where the external server 30 performs the driving diagnosis based on the vehicle-related information received from the vehicle 20 and the external server 30 wirelessly transmits the result information of this driving diagnosis to the vehicle 20, the result information can be quickly displayed on the display 28. Therefore, the driver Dr can immediately recognize the result information caused by his / her own driving operation by looking at the display 28. That is, when the driver Dr performs a problematic driving operation, he / she can immediately recognize it.

[0093] Furthermore, vehicle-related information (second data) for performing normal driving diagnosis with the output destination being the mobile terminal 40 is transmitted to the external server 30. Therefore, the driver Dr can recognize the result information of the normal driving diagnosis generated by the external server 30 by looking at the display 41 of the mobile terminal 40, for example, after finishing driving the vehicle 20. Furthermore, since the normal driving diagnosis is executed using more data and machine learning than the real-time driving diagnosis, the reliability of the normal driving diagnosis is high.

[0094] Furthermore, vehicle-related information (third data) for performing insurance driving diagnosis is transmitted to the external server 30 that has received authentication from the insurance company, and the insurance driving diagnosis is executed by the external server 30. That is, when the type of driving diagnosis is insurance driving diagnosis, the vehicle-related information (third data) is transmitted to the external server 30 that has received authentication from the insurance company. Therefore, the insurance company that has received the result information of the insurance driving diagnosis can design insurance products based on reliable result information.

[0095] In addition, the out-vehicle image data and face image data, which are vehicle-related information with a large data volume, are transmitted to the ECU 21 while not being wirelessly transmitted to the external server 30. Therefore, the load of wireless communication between the vehicle 20 and the external server 30 can be reduced.

[0096] In this way, the system 10 can transmit vehicle-related information to a plurality of driving diagnosis units (ECU 21, external server 30) while considering various conditions related to driving diagnosis.

[0097] Furthermore, vehicle-related information acquired at a first frequency that is equal to or higher than a first threshold value is transmitted only to the ECU 21 without being transmitted to the external server 30. Therefore, the data volume of the vehicle-related information wirelessly transmitted from the vehicle 20 to the external server 30 can be suppressed.

[0098] Furthermore, some of the result information generated by the ECU 21 (drowsiness determination data, speed limit violation data, and PCS operation data) is transmitted from the vehicle 20 to the external server 30, and the external server 30 uses this result information to perform normal driving diagnosis. Therefore, the external server 30 can execute normal driving diagnosis without performing driving diagnosis with the same content as the ECU 21.

[0099] Furthermore, the administrator or driver Dr of the external server 30 can arbitrarily change the content of the data classification list 29. Therefore, for example, if the driver Dr wishes not to display the result information of the real-time driving diagnosis on the display 28, the administrator or driver Dr may update the content of the data classification list 29 so as not to include the first data. Also, for example, if an insurance company wishes to include drowsiness determination data in the driving diagnosis for insurance purposes, the content of the data classification list 29 may be updated so that the face image data becomes the third data, and a function corresponding to the wakefulness estimation unit 202 may be provided to the external server 30.

[0100] As described above, the driving diagnosis device, system, driving diagnosis method, and program according to the embodiment have been described, but these can be appropriately designed and changed within a range not departing from the gist of the present invention.

[0101] For example, the vehicle 20 may be redesigned so that the result information of the real-time driving diagnosis is not displayed on the display 28. This design change can be executed, for example, using the display 28 (touch panel).

[0102] The ECU 21 and the external server 30 may perform driving diagnosis with overlapping content. For example, if an insurance company wishes to include speed limit violation data in the driving diagnosis for insurance purposes, the external server 30 may generate speed limit violation data using the acquisition data of the wheel speed sensor 22 received from the vehicle 20, the position data of the vehicle 20, and the map data, and include this speed limit violation data in the result information of the driving diagnosis for insurance purposes.

[0103] The vehicle 20 may wirelessly transmit at least one of the outside-vehicle image data and the face image data to the external server 30. However, in this case, it is preferable that the ECU 21 wirelessly transmits the image data to the external server 30 after compressing the capacity of the image data. In this way, the external server 30 can execute normal driving diagnosis and insurance driving diagnosis while using the image data.

[0104] The insurance company may authenticate the vehicle 20 (ECU 21). In this way, the result information of the real-time driving diagnosis generated by the ECU 21 can be included in the insurance driving diagnosis.

[0105] Furthermore, the result information of the normal driving diagnosis generated by the external server 30 may include information (recommendation information) about a vehicle (vehicle type) that the external server 30 determines has good compatibility with the driver Dr based on the diagnosis result. In this way, the driver Dr who sees the display 41 of the mobile terminal 40 can know the vehicle that is easy to drive for himself / herself.

[0106] Also, the result information of the real-time driving diagnosis may be displayed on the display 41 of the mobile terminal 40 located inside the vehicle 20.

[0107] The result information of each driving diagnosis may be output as sound. For example, the result information of the real-time driving diagnosis may be output from a speaker (not shown) provided in the vehicle 20.
