[0009] [1. Information Processing System Configuration] FIG. 1 is a diagram showing the configuration of an information processing system 1. As shown in FIG. The information processing system 1 includes a vehicle 2 and a server device 3. The vehicle 2 may be a four-wheeled vehicle or a vehicle other than a four-wheeled vehicle. The vehicle 2 is an example of a "moving body."

[0010] The vehicle 2 is equipped with a TCU (Telematics Control Unit) 21, and communicates with a server device 3 connected to a network NW via the TCU 21. The network NW is a communication network made up of a public line network, a dedicated line, other communication circuits, etc. The vehicle 2 transmits upload data 6 to the server device 3. The upload data 6 is data to be uploaded to the server device 3. The vehicle 2 transmits the upload data 6 to the server device 3 when the ignition power of the vehicle 2 is turned from on to off, or when the vehicle 2 receives transmission instruction data 7 from the server device 3 indicating an instruction to transmit the upload data 6. Details of the upload data 6 will be described later. The TCU 21 is an example of a "communication device."

[0011] The server device 3 is a device that processes information using devices connected to the network NW as clients. The server device 3 of this embodiment performs processing such as data analysis on the upload data 6 received from the vehicle 2, and notifies a smartphone 4 used by a user P of the vehicle 2 and a PC (Personal Computer) 5 used by a dealer DL of the vehicle 2 of information acquired from the upload data 6. By analyzing the upload data 6, the server device 3 of this embodiment notifies that the vehicle 2 has malfunctioned and information including the details of the malfunction.

[0012] [2. Vehicle configuration] The configuration of the vehicle 2 will be described with reference to FIG. The vehicle 2 includes a vehicle control device 20, a TCU 21, a display device 22, a switch 23, an ignition sensor 24, a GNSS (Global Navigation Satellite System) receiver 25, and a vehicle speed sensor 26.

[0013] The vehicle control device 20 includes a first processor 200 such as a CPU (Central Processing Unit) or an MPU (Micro-Processing Unit), a first memory 210, and an interface circuit to which other devices and sensors are connected.

[0014] The first memory 210 is a storage device that nonvolatilely stores programs and data executed by the first processor 200. The first memory 210 is configured by a semiconductor storage element such as a magnetic storage device or a flash ROM (Read Only Memory), or other types of nonvolatile storage devices. The first memory 210 may also include a RAM (Random Access Memory) that configures a work area for the first processor 200. The first memory 210 may also include a nonvolatile storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive). The first memory 210 stores data processed by the first processor 200 and a first control program 211 executed by the first processor 200.

[0015] The vehicle control device 20 is connected to a TCU 21, a display device 22, an ignition sensor 24, a GNSS receiver 25, and a vehicle speed sensor 26. Note that the devices connected to the vehicle control device 20 are not limited to these devices and may include other types of devices.

[0016] The TCU 21 includes a TCU control unit 30 and a TCU communication unit 31 . The TCU control device 30 includes a second processor 300 such as a CPU or MPU, a second memory 310, and an interface circuit to which other devices and sensors are connected. The second processor 300 is an example of a "processor."

[0017] The second memory 310 is a storage device that nonvolatilely stores programs and data executed by the second processor 300. The second memory 310 is configured by a semiconductor storage element such as a magnetic storage device or a flash ROM, or other types of nonvolatile storage devices. The second memory 310 may also include a RAM that configures a work area for the second processor 300. The second memory 310 may also include a nonvolatile storage device such as an HDD or SSD. The second memory 310 stores data processed by the second processor 300 and a second control program 311 executed by the second processor 300. The second control program 311 is an example of a "program."

[0018] The TCU communication unit 31 includes communication hardware such as a wireless communication circuit, and communicates with the server device 3 under the control of the TCU control device 30.

[0019] The display device 22 is a device provided on the meter panel of the instrument panel, and is a multi-information display (MID). The display device 22 notifies the driver of the status of the vehicle 2 by displaying information. The notification content notified by the display device 22 is broadly divided into normal content and fault content. The normal content indicates the status of the vehicle 2 when there is no fault in the vehicle 2. Examples of normal content include the door of the vehicle 2 being open or the vehicle 2 being low on gas. The fault content indicates that the vehicle 2 is in a fault state. Examples of fault content include the engine failing or the brake failing.

[0020] An image ID (Identification) 8 is assigned to each of the notification contents notified by the display device 22. The image ID 8 is data that uniquely identifies the notification content displayed by the display device 22. Note that the image ID 8 is not assigned to the normal content and the fault content described above, but is assigned to each of the more detailed notification contents that subdivide the normal content and the fault content. A value indicating the state of the vehicle 2 (hereinafter referred to as a "state value") is recorded in the image ID 8. The state value recorded in the image ID is different for each of the notification contents notified by the display device 22. Note that the state value recorded in the image ID 8 is different for each of the more detailed notification contents that subdivide the normal content and the fault content. The display device 22 outputs an image ID8 corresponding to the notification content being notified to the TCU 21. The display device 22 stores a table in a predetermined storage area in which the notification content and the image ID8 are associated with each other, and outputs the image ID8 corresponding to the notification content being notified to the TSU 21 by referring to the table.

[0021] A switch 23 is connected to the display device 22. The switch 23 is provided on a steering wheel that steers the vehicle 2. The switch 23 is a switch for switching the notification content notified by the display device 22 to another notification content. When the switch 23 is operated, the display device 22 switches the currently displayed status information of the vehicle 2 to another status information of the vehicle 2 that has been displayed since the ignition power of the vehicle 2 was turned on. The display device 22 can redisplay the status information of the vehicle 2 that has been displayed in the past since the ignition power of the vehicle 2 was turned on. Therefore, by operating the switch 23 multiple times, the user of the vehicle 2 can cause the display device 22 to redisplay the status information of the vehicle 2 that has already been displayed since the ignition power of the vehicle 2 was turned on. When the notification content to be notified is switched, the display device 22 outputs an image ID8 corresponding to the switched notification content to the TCU 21.

[0022] The ignition sensor 24 is a sensor that detects whether the ignition power supply of the vehicle 2 is on or off. The ignition sensor 24 outputs power supply state data 9-1 indicating whether the ignition power supply is on or off to the vehicle control device 20.

[0023] The GNSS receiver 25 is a device that detects the current position of the vehicle 2, and receives positioning signals transmitted from a plurality of positioning satellites. The GNSS receiver 25 outputs current position data 9-2 indicating the current position of the vehicle 2 to the vehicle control device 20.

[0024] The vehicle speed sensor 26 is a sensor that detects the speed of the vehicle 2. The vehicle speed sensor 26 outputs vehicle speed data 9-3 indicating the speed of the vehicle 2 to the vehicle control device 20.

[0025] The power supply status data 9-1, the current location data 9-2, and the vehicle speed data 9-3 are data that may change over time and are data related to the vehicle 2. Hereinafter, when the power supply status data 9-1, the current location data 9-2, and the vehicle speed data 9-3 are not distinguished from one another, they will be referred to as "vehicle data" and marked with the number "9." The vehicle data 9 is an example of "second data."

[0026] The first processor 200 of the vehicle control device 20 reads and executes a first control program 211 stored in a first memory 210, thereby functioning as a data output unit 201 and a vehicle state detection unit 202.

[0027] The data output unit 201 outputs the vehicle data 9 to the TCU 21 .

[0028] The vehicle state detection unit 202 detects the state of the vehicle 2. The vehicle state detection unit 202 outputs the detection result to the display device 22. The display device 22 notifies the user of the state of the vehicle 2 indicated by the detection result received from the vehicle state detection unit 202. For example, the vehicle state detection unit 202 detects whether a door is open, as the state of the vehicle 2, based on a signal from a door switch that detects whether the door is open or closed. Also, for example, the vehicle state detection unit 202 detects whether the gasoline is running low, based on a signal from a sensor that detects the position of a float in the fuel tank. Also, for example, the vehicle state detection unit 202 detects whether the engine is malfunctioning, based on signals from a sensor that detects engine oil, a sensor that detects overheating, or the like. For example, the vehicle state detection unit 202 detects whether the brakes are malfunctioning, based on signals from a sensor that detects brake oil pressure, or the like.

[0029] [3. Functional Unit of Second Processor] Next, the functional units of the second processor 300 will be described. FIG. 2 is a diagram illustrating the functional units of the second processor 300. As shown in FIG.

[0030] The second processor 300 reads and executes the second control program 311 to function as a receiving unit 301 , a transmitting unit 302 , a recording trigger generating unit 303 , an upload trigger generating unit 304 , and a recording unit 305 . The recording trigger generating unit 303 is an example of a "recording data control unit."

[0031] [3-1. Receiving section] The receiving unit 301 receives transmission instruction data 2 from the server device 3 via the TCU communication unit 31. When the receiving unit 301 receives transmission instruction data 7 from the server device 3, the receiving unit 301 outputs the received transmission instruction data 7 to the recording trigger generating unit 303, the upload trigger generating unit 304, and the recording unit 305.

[0032] [3-2. Recording trigger generation section] The recording trigger generating unit 303 causes the recording unit 305 to record an image ID8 whose status value indicates a specific value after the ignition power of the vehicle 2 is turned on, and restricts the recording unit 305 from recording the image ID8 again until a predetermined condition is met after the image ID8 indicating the specific value is recorded. The image ID8 whose status value indicates a specific value is an example of "first data." Here, the predetermined condition is that the ignition power is turned off.

[0033] The recording trigger generating unit 303 generates a trigger in the recording unit 305 to record an image ID 8 indicating a specific value and vehicle data 9. The recording trigger generating unit 303 receives the image ID 8 output by the display device 22. The recording trigger generating unit 303 also receives from the receiving unit 301 the transmission instruction data received by the receiving unit 301. The recording trigger generating unit 303 generates a first trigger or a second trigger in the recording unit 305.

[0034] Here, the operation of the recording trigger generating unit 303 when the first trigger is generated will be described. FIG. 3 is a flowchart showing the operation of the recording trigger generating unit 303.

[0035] The recording trigger generating unit 303 determines whether or not the image ID8 has been received from the display device 22 (step SA1).

[0036] If the recording trigger generating unit 303 determines that the image ID8 has not been received from the display device 22 (step SA1: NO), it performs the determination in step SA1 again.

[0037] When the recording trigger generating unit 303 determines that it has received image ID8 from the display device 22 (step SA1: YES), it determines whether the image ID8 received from the display device 22 is the first type of image ID8 received since the ignition power was turned on (step SA2). The determination in step SA2 is made based on the status value recorded in the image ID8. The recording trigger generating unit 303 records the status value of image ID8 received from the display device 22 after the ignition power of the vehicle 2 is turned on in a predetermined storage area, and makes the determination in step SA2 by referring to the status value recorded in the predetermined storage area.

[0038] If the recording trigger generating unit 303 determines that the image ID8 is not of the type that has been received for the first time since the ignition power was turned on (step SA2: NO), the recording trigger generating unit 303 returns the process to step SA1.

[0039] On the other hand, if the recording trigger generating unit 303 determines that the image ID8 is the type that has been received for the first time since the ignition power was turned on (step SA2: YES), it determines whether the image ID8 is the image ID8 that the recording unit 305 is to record (step SA3). In this embodiment, the image ID8 that the recording unit 305 is to record is the image ID8 that corresponds to the notification content that belongs to the fault content. The status value (specific value) of the image ID8 that the recording unit 305 is to record is recorded in a predetermined storage area, and the recording trigger generating unit 303 makes the determination in step SA3 based on whether the status value of the image ID8 received from the display device 22 is the specific value recorded in the predetermined storage area.

[0040] If the recording trigger generating unit 303 determines that the image ID8 is not the image to be recorded by the recording unit 305 (step SA3: NO), the recording trigger generating unit 303 returns the process to step SA1.

[0041] On the other hand, if the recording trigger generation unit 303 determines that the image ID8 is to be recorded by the recording unit 305 (step SA3: YES), it generates a first trigger for the recording unit 305 (step SA4). Specifically, the recording trigger generation unit 303 transmits first trigger information indicating the first trigger to the recording unit 305.

[0042] Next, the operation of the recording trigger generating unit 303 when the second trigger is generated will be described. FIG. 4 is a flowchart showing the operation of the recording trigger generating unit 303.

[0043] The recording trigger generating unit 303 determines whether or not the transmission instruction data 2 has been received from the receiving unit 301 (step SB1).

[0044] If the recording trigger generating unit 303 determines that the transmission instruction data 2 has not been received from the receiving unit 301 (step SB1: NO), it performs the determination in step SB1 again.

[0045] If the recording trigger generating unit 303 determines that it has received transmission instruction data 2 from the receiving unit 301 (step SB1: YES), it generates a second trigger for the recording unit 305 (step SB2). Specifically, the recording trigger generating unit 303 transmits second trigger information indicating the second trigger to the recording unit 305.

[0046] [3-3. Recording Section] The recording unit 305 receives the image ID 8 from the display device 22. The types of image ID 8 received by the recording unit 305 and the recording trigger generation unit 302 are the same. The recording unit 305 also receives the vehicle data 9 from the vehicle control device 20. When the first trigger is generated by the recording trigger generation unit 303, the recording unit 305 associates the latest image ID 8 received from the display device 22 with the latest vehicle data 9 received from the vehicle control device 20 and records them in the second memory 310. The data recorded by the recording unit 305 is erased from the second memory 310 when the ignition power of the vehicle 2 is turned from on to off.

[0047] FIG. 5 is a flowchart showing the operation of the recording unit 305. The recording unit 305 determines whether or not the first trigger has occurred (step SC1). If the recording unit 305 determines that the first trigger has not occurred (step SC1: NO), it performs the determination of step SC1 again.

[0048] On the other hand, if the recording unit 305 determines that the first trigger has occurred (step SC1: YES), it records the image ID 8 received from the display device 22 and the vehicle data 9 received from the vehicle control device 20 in association with each other (step SC2).

[0049] When the second trigger is generated by the recording trigger generating unit 303, the recording unit 305 does not record the image ID 8 received from the display device 22, but records the vehicle data 9 received from the vehicle control device 20. Specifically, when the second trigger is generated by the recording trigger generating unit 303, the recording unit 305 records the vehicle data 9 associated with null data in the second memory 310.

[0050] FIG. 6 is a flowchart showing the operation of the recording unit 305. The recording unit 305 determines whether or not a second trigger has occurred (step SD1). If the recording unit 305 determines that a second trigger has not occurred (step SD1: NO), it performs the determination of step SD1 again.

[0051] On the other hand, if the recording unit 305 determines that the second trigger has occurred (step SD1: YES), it records the vehicle data 9 associated with null data (step SD2).

[0052] When a third trigger is generated from the upload trigger generating unit 304 described later, the recording unit 305 generates upload data 6 including the image ID 8 and vehicle data 9 recorded in the second memory 210, and outputs the generated upload data 6 to the transmitting unit 302.

[0053] FIG. 7 is a flowchart showing the operation of the recording unit 305. The recording unit 305 determines whether or not a third trigger has occurred (step SE1). If the recording unit 305 determines that the third trigger has not occurred (step SE1: NO), it performs the determination of step SE1 again.

[0054] On the other hand, if it is determined that the third trigger has occurred (step SE1: YES), the recording unit 305 generates upload data 6 (step SE2).

[0055] Next, recording unit 305 outputs the generated upload data 6 to transmission unit 302 (step SE3).

[0056] [3-4. Upload trigger generation section] The upload trigger generating unit 304 causes the recording unit 305 to generate a third trigger, which is a trigger for transmitting the upload data 6. The upload trigger generating unit 304 receives the power supply status data 9-1 from the vehicle control device 20. Furthermore, when the receiving unit 301 receives the transmission instruction data 7, the upload trigger generating unit 304 receives the transmission instruction data 7 from the receiving unit 301.

[0057] FIG. 8 is a flowchart showing the operation of the upload trigger generating unit 304. The upload trigger generating unit 304 determines whether the ignition power of the vehicle 2 has changed from on to off based on the power supply state data 9-1 received from the vehicle control device 20 (step SF1).

[0058] If the upload trigger generating unit 304 determines that the ignition power of the vehicle 2 has changed from on to off (step SF1: YES), it performs the process of step SF2.

[0059] If the upload trigger generating unit 304 determines that the ignition power of the vehicle 2 has not been turned off (step SF1: NO), it determines whether or not the upload trigger generating unit 304 has received the transmission instruction data 7 from the receiving unit 301 (step SF3).

[0060] If the upload trigger generating unit 304 determines that the transmission instruction data 7 has not been received (step SF3: NO), it returns the process to step SF1. On the other hand, if the upload trigger generating unit 304 determines that the transmission instruction data 7 has been received (step SF3: YES), it performs the process of step SF2.

[0061] In step SF2, the upload trigger generating unit 304 determines whether or not recording in the recording unit 305 has finished (step SF2). If the upload trigger generating unit 304 determines that recording in the recording unit 305 has not finished (step SF2: NO), it performs the determination in step SF2 again.

[0062] On the other hand, if it is determined that recording by the recording unit 305 has finished (step SF2: YES), the upload trigger generating unit 304 causes the recording unit 305 to generate a third trigger (step SF4). Specifically, the upload trigger generating unit 304 outputs third trigger information indicating the third trigger to the recording unit 305.

[0063] [3-5.Transmitter] The transmitting unit 302 transmits the upload data 6 received from the recording unit 305 to the server device 3 .

[0064] Next, the operation of the TCU 21 will be specifically described with reference to FIG. Fig. 9 is a timing chart for explaining recording by the recording unit 305 and transmission by the transmission unit 302. In Fig. 9, chart C1 shows the image ID 8 and vehicle data 9 recorded by the recording unit 305, and the upload data 6 transmitted by the transmission unit 302. Also in Fig. 9, chart C2 shows the type of image ID 8 output by the display device 22. Also in Fig. 9, chart C3 shows the state of the ignition power supply of the vehicle 2.

[0065] In the example of FIG. 9, a case will be described in which the recording unit 305 records power supply status data 9-1 as the vehicle data 9.

[0066] In the example of FIG. 9, the status value recorded in image ID 8 is indicated by a two-digit number. In the example of FIG. 9, image ID 8 in which any of status values: 14, 15, 16, 18, and 19 is recorded is the image ID 8 to be recorded. That is, in the example of FIG. 9, status values: 14, 15, 16, 18, and 19 are specific values. Therefore, image ID 8 in which any of status values: 14, 15, 16, 18, and 19 is recorded is the image ID 8 corresponding to the fault content. In the example of FIG. 9, a two-digit number is shown as the status value, but the status value may be a number other than two digits, and the number may include letters and symbols.

[0067] In FIG. 9, the ignition power of the vehicle 2 is turned on at timing T1. When the ignition power is turned on, at timing T1, the display device 22 notifies the notification content corresponding to the image ID 8 in which the status value: 01 is recorded, and along with this notification, outputs the image ID 8 in which the status value: 01 is recorded to the TCU 21. In the example of FIG. 9, the image ID 8 in which the status value: 01 is recorded is not the image ID 8 to be recorded. Therefore, the image ID 8 in which the status value: 01 is recorded is not recorded in the recording unit 305.

[0068] 9, at timing T2, the display device 22 notifies the notification content corresponding to the image ID8 in which the status value: 02 is recorded, and along with this notification, outputs the image ID8 in which the status value: 02 is recorded to the TCU 21. In the example of FIG. 9, the image ID8 in which the status value: 02 is recorded is not the image ID8 to be recorded. Therefore, the image ID8 in which the status value: 02 is recorded is not recorded in the recording unit 305.

[0069] 9, at timing T3, the display device 22 notifies the display device 21 of notification content corresponding to the image ID 8 in which the status value: 14 is recorded, and along with this notification, outputs the image ID 8 in which the status value: 14 is recorded to the TCU 21. In the example of FIG. 9, the image ID 8 in which the status value: 14 is recorded is the image ID 8 to be recorded. Therefore, at timing T3, the recording unit 305 associates the image ID 8 in which the status value: 14 is recorded with the power status data 9-1 indicating that the ignition power is on, and records the image ID 8 in which the status value: 14 is recorded.

[0070] 9, at timing T4, the display device 22 again notifies the user of the notification content corresponding to the image ID 8 in which the status value: 02 is recorded. In response to this notification, the display device 22 outputs the image ID 8 in which the status value: 02 is recorded to the TCU 21 at timing T4. However, the image ID 8 in which the status value: 02 is recorded is not recorded in the recording unit 305.

[0071] 9, at timing T5, the display device 22 notifies the display device 21 of notification content corresponding to the image ID 8 in which the status value: 15 is recorded, and along with this notification, outputs the image ID 8 in which the status value: 15 is recorded to the TCU 21. In the example of FIG. 9, the image ID 8 in which the status value: 15 is recorded is the image ID 8 to be recorded. Therefore, at timing T5, the recording unit 305 associates the image ID 8 in which the status value: 15 is recorded with the power status data 9-1 indicating that the ignition power is on, and records the image ID 8 in which the status value: 15 is recorded.

[0072] When the switch 23 is operated, at timing T6 in FIG. 9, the display device 22 again notifies the display device 22 of the notification content corresponding to the image ID 8 in which the status value: 14 is recorded. In response to this notification, the display device 22 outputs the image ID 8 in which the status value: 14 is recorded to the TCU 21 at timing T6. However, the image ID 8 output at timing T6 is not the type of image ID 8 that is output to the TCU 21 for the first time after the ignition power is turned on. Therefore, the recording trigger generation unit 303 does not generate the first trigger at timing T6, and the recording unit 305 does not record the image ID 8 in which the status value: 14 is recorded at timing T6.

[0073] 9, at timing T7, the display device 22 notifies the display device 21 of notification content corresponding to the image ID 8 in which the status value: 16 is recorded, and along with this notification, outputs the image ID 8 in which the status value: 16 is recorded to the TCU 21. In the example of FIG. 9, the image ID 8 in which the status value: 16 is recorded is the image ID 8 to be recorded. Therefore, at timing T7, the recording unit 305 associates the image ID 8 in which the status value: 16 is recorded with the power status data 9-1 indicating that the ignition power is on, and records the image ID 8 in which the status value: 16 is recorded.

[0074] 9, at timing T8, the display device 22 notifies the notification content corresponding to the image ID8 in which the status value: 03 is recorded, and along with this notification, outputs the image ID8 in which the status value: 03 is recorded to the TCU 21. In the example of FIG. 9, the image ID8 in which the status value: 03 is recorded is not the image ID8 to be recorded. Therefore, the image ID8 in which the status value: 03 is recorded is not recorded in the recording unit 305.

[0075] In FIG. 9 , at timing T9, the receiving unit 301 receives the transmission instruction data 7 from the server device 3. In response to this reception, at timing T9, the recording unit 305 records the power status data 9-1 associated with null data. When the recording unit 305 finishes this recording, the upload trigger generating unit 304 generates a third trigger, and the transmitting unit 302 transmits the upload data 6-1 to the server device 3 at timing T9 or later. The upload data 6-1 includes the image ID 8 and vehicle data 9 recorded after the ignition power was turned on. In detail, the upload data 6-1 includes a combination of the image ID and power status data 9-1 with a status value of 14, a combination of the image ID 8 and power status data 9-1 with a status value of 15, a combination of the image ID 8 and power status data 9-1 with a status value of 16, and a combination of null data and power status data 9-1.

[0076] When the switch 23 is operated, at timing T10 in FIG. 9, the display device 22 again notifies the display device 22 of the notification content corresponding to the image ID8 in which the status value: 16 is recorded. In response to this notification, the display device 22 outputs the image ID8 in which the status value: 16 is recorded to the TCU 21 at timing T10. However, the image ID8 output at timing T10 is not the type of image ID8 that is output to the TCU 21 for the first time after the ignition power is turned on. Therefore, the recording trigger generation unit 303 does not generate the first trigger at timing T10, and the recording unit 305 does not record the image ID8 in which the status value: 16 is recorded at timing T10.

[0077] 9, at timing T11, the display device 22 notifies the display device 21 of notification content corresponding to the image ID 8 in which the status value: 18 is recorded, and along with this notification, outputs the image ID 8 in which the status value: 18 is recorded to the TCU 21. In the example of FIG. 9, the image ID 8 in which the status value: 18 is recorded is the image ID 8 to be recorded. Therefore, at timing T11, the recording unit 305 associates the image ID 8 in which the status value: 18 is recorded with the power status data 9-1 indicating that the ignition power is on, and records the image ID 8 in which the status value: 18 is recorded.

[0078] In FIG. 9 , at timing T12, the receiving unit 301 receives the transmission instruction data 7 from the server device 3. In response to this reception, at timing T12, the recording unit 305 records the power status data 9-1 associated with null data. When the recording unit 305 finishes this recording, the upload trigger generating unit 304 generates a third trigger, and the transmitting unit 302 transmits the upload data 6-2 to the server device 3. The upload data 6-2 includes the image ID 8 and the vehicle data 9 recorded after the ignition power is turned on. In detail, the upload data 6-2 includes a combination of the image ID and the power status data 9-1 with a status value of 14, a combination of the image ID 8 and the power status data 9-1 with a status value of 15, a combination of the image ID 8 and the power status data 9-1 with a status value of 16, a combination of the image ID 8 and the power status data 9-1 with a status value of 18, and a combination of the null data and the power status data 9-1.

[0079] 9, at timing T13, the display device 22 notifies the display device 21 of the notification content corresponding to the image ID 8 in which the status value: 19 is recorded, and along with this notification, outputs the image ID 8 in which the status value: 19 is recorded to the TCU 21. In the example of FIG. 9, the image ID 8 in which the status value: 19 is recorded is the image ID 8 to be recorded. Therefore, at timing T13, the recording unit 305 associates the image ID 8 in which the status value: 19 is recorded with the power status data 9-1 indicating that the ignition power is on, and records the image ID 8 in which the status value: 19 is recorded.

[0080] In FIG. 9, at timing T14, the ignition power of vehicle 2 changes from off to on. In response to this reception, at timing T14, recording unit 305 records power status data 9-1 associated with null data. When this recording by recording unit 305 ends, upload trigger generation unit 304 generates a third trigger, and transmission unit 302 transmits upload data 6-3 to server device 3. Upload data 6-3 includes image ID 8 and vehicle data 9 that were recorded after the ignition power was turned on. In detail, the upload data 6-2 includes a combination of image ID and power status data 9-1 with a status value of 14, a combination of image ID 8 and power status data 9-1 with a status value of 15, a combination of image ID 8 and power status data 9-1 with a status value of 16, a combination of image ID 8 and power status data 9-1 with a status value of 18, a combination of image ID 8 and power status data 9-1 with a status value of 19, and a combination of null data and power status data 9-1.
