[0002] This application is based on Japanese Patent Application No. 2023-222246, filed on December 28, 2023, the contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to a data communication system, a central device, a vehicle device, a data processing method, and a data processing program. Background Technology

[0004] A data communication system is provided in which vehicle data is collected from an unspecified number of vehicle devices by receiving vehicle data transmitted from vehicle devices mounted on an unspecified number of vehicles in a central device. For example, Patent Document 1 discloses a technique for reducing the frequency of sending access requests from vehicle devices to the central device and reducing the processing load for authentication used to collect vehicle data.

[0008] There are situations where users feel dissatisfied while using a vehicle. As a technique for determining user dissatisfaction, it is envisioned that the situation can be determined directly or indirectly. For example, while driving on a highway, if a user performs a steering maneuver during the execution of Lane Tracing Assist (LTA) functionality, user dissatisfaction can be directly determined by confirming the cancellation of the LTA function. Similarly, if the use of the automatic parking function is recommended at the start of a parking maneuver, user dissatisfaction can be directly determined by confirming the rejection of the automatic parking function. Furthermore, after improving the LTA function based on feedback from other users, user dissatisfaction can be indirectly determined by determining that the logical behavior of the LTA function's actions differs from the improved logical behavior. Due to these considerations, there is a desire, among vehicle manufacturers and application development vendors, to analyze scenarios of user dissatisfaction and improve vehicle functionality.

[0009] In this scenario, a trigger condition is created in the central device to detect situations where the user is dissatisfied. This is achieved by collecting and analyzing sensor values ​​from various sensors and control states of various systems before and after the trigger condition is triggered, as well as data collected from vehicle-mounted devices. However, the trigger condition is not limited to a single one; sometimes, switching between multiple trigger conditions is desirable for efficient improvement of vehicle functionality.

[0039] The embodiments will now be described with reference to the accompanying drawings. Figure 1 As shown, the data communication system 1 is configured as a central device 2 and a vehicle device 4 mounted on each of a plurality of vehicles 3, which can perform data communication via a wide area wireless communication network 5.

[0040] like Figure 2As shown, the central device 2 includes a control unit 6, a communication unit 7, and a storage unit 8. The control unit 6 is primarily composed of a microcomputer (hereinafter referred to as a microcomputer) equipped with a CPU, ROM, RAM, and I / O, etc. It controls the operation of the central device 2 by executing a computer program stored in a non-transitional physical storage medium via the CPU, performing software-based processing and hardware processing based on dedicated electronic circuits. By executing the computer program, the corresponding method is executed. The number of microcomputers constituting the control unit 6 can be one or more. The communication unit 7 controls data communication with multiple vehicle-use devices 4 via a wide-area wireless communication network 5. The storage unit 8 stores various types of data.

[0041] like Figure 3 As shown, the vehicle device 4 includes a control unit 9, a communication unit 10, a storage unit 11, and a CAN (Controller Area Network) communication unit 12. The control unit 9 is primarily composed of a microcomputer with a CPU, ROM, RAM, and I / O, etc. It controls the operation of the vehicle device 4 by executing a computer program stored in a non-transferable physical storage medium via the CPU, performing software-based processing and hardware processing based on dedicated electronic circuits. By executing the computer program, the corresponding method is executed. The number of microcomputers constituting the control unit 9 can be one or more. The communication unit 10 controls data communication with the central device 2 via a wide-area wireless communication network 5. The storage unit 11 stores various data.

[0042] The CAN communication unit 12 is connected to CAN buses 13-15. The CAN communication unit 12 is connected to multiple ECUs 161-16n via CAN bus 13 in a manner enabling data communication. These multiple ECUs 161-16n include, for example, an engine ECU for engine control, a throttle ECU for throttle control, a brake ECU for braking control, a steering ECU for steering control, an instrument ECU for instrument control, and a navigation ECU for navigation control. For example, the throttle ECU sends data showing the throttle opening to the CAN communication unit 12 as detection data. For example, the brake ECU sends data showing the brake pedal operation amount to the CAN communication unit 12 as detection data. For example, the steering ECU sends data showing the steering angular velocity to the CAN communication unit 12 as detection data. For example, the navigation ECU sends data showing latitude and longitude to the CAN communication unit 12 as detection data. The multiple ECUs 161-16n are connected to the same bus according to their respective systems; for example, the ECUs for the ADAS (Advanced Driving Assistant System), the body system, and the chassis system are each connected to the same bus.

[0043] The CAN communication unit 12 is connected to multiple cameras 171-17n and multiple sensors 181-18n via the CAN bus 14 in a manner capable of data communication. The multiple cameras 171-17n include, for example, a front-facing camera capturing images of the front of the vehicle, an interior-facing camera capturing images of the interior of the vehicle, and a driver's camera capturing images of the driver. For example, the front-facing camera capturing images of the front of the vehicle sends data showing the image captured to the CAN communication unit 12 as detection data. Similarly, the interior-facing camera sends data showing the image captured of the interior of the vehicle to the CAN communication unit 12 as detection data. The multiple sensors 181-18n include, for example, LIDAR (Light Detection and Ranging, Laser Imaging), millimeter-wave radar, ultrasonic sensors, illuminance sensors, and rain sensors. For example, sensors that detect the front of the vehicle, such as LIDAR or millimeter-wave radar, send data showing the distance to preceding vehicles to the CAN communication unit 12 as detection data. Similarly, the illuminance sensor sends data showing illuminance to the CAN communication unit 12 as detection data. For example, the rain sensor sends data showing the amount of rainfall to the CAN communication unit 12 as detection data.

[0044] The CAN communication unit 12 is connected to the DSM (Driver Status Monitor) 19, Lane Warning System 20, Lane Keeping System 21, and ACC (Adaptive Cruise Control) System 22 via the CAN bus 15 in a manner capable of data communication. For example, the DSM 19 sends data indicating the driver's status to the CAN communication unit 12 as detection data. For example, the Lane Warning System 20 sends data indicating its control status to the CAN communication unit 12 as detection data. For example, the Lane Keeping System 21 sends data indicating its control status to the CAN communication unit 12 as detection data. For example, the ACC System 22 sends data indicating its control status to the CAN communication unit 12 as detection data.

[0045] The number of CAN bus lines 13-15 connected to the CAN communication unit 12 is not limited to three; it can be two or fewer, or four or more. Various ECUs 161-16n, various cameras 171-17n, various sensors 181-18n, DSM19, and various systems 20-22 can be connected to the CAN bus lines 13-15 in any way. The devices connected to the CAN bus lines 13-15 are not limited to the aforementioned ECUs, cameras, sensors, and systems. Furthermore, the in-vehicle communication network is not limited to the CAN bus line 13-15 structure; it can also use Ethernet or other structures. Ethernet is a registered trademark.

[0046] like Figure 4 As shown, in the central device 2, the control unit 6, as its various functions, includes a trigger condition creation unit 6a, a data collection overview creation unit 6b, a switching information creation unit 6c, a distribution unit 6d, and a data collection acquisition unit 6e. Through these parts 6a to 6e, the data processing method of the central device 2 is executed, and the data processing program of the central device 2 is executed.

[0047] Trigger condition creation unit 6a creates multiple trigger conditions for detecting scenarios where users have complaints (equivalent to scenarios defined on the vehicle side). Data collection overview creation unit 6b creates a data collection overview corresponding to each of the multiple trigger conditions. Switching information creation unit 6c creates switching conditions and priorities corresponding to each trigger condition and each data collection overview as switching information. Distribution unit 6d distributes the multiple trigger conditions created by trigger condition creation unit 6a, the data collection overview created by data collection overview creation unit 6b, and the switching conditions and priorities created by switching information creation unit 6c from communication unit 7 to vehicle device 4. Data collection acquisition unit 6e acquires data from vehicle device 4 by receiving the data sent from vehicle device 4 via communication unit 7.

[0048] The switching of trigger conditions and the overview of collected data can be initiated by the central device 2 or by the vehicle side. The following will explain each situation.

[0049] (1) When the central device 2 issues a switching instruction

[0050] When determining a handover instruction from central device 2, vehicle device 4 performs a handover triggering condition and collects a list of data. For example, before handover, vehicle device 4 sends simple data such as vehicle speed when ACC system 22 is disconnected and user operation data to central device 2. Upon receiving a handover instruction from central device 2 and determining that a handover instruction has been received, vehicle device 4 performs a handover logic, and after handover, also sends data such as the presence or absence of surrounding vehicles to central device 2. Examples of triggering condition ID, collected data, handover conditions, and priorities are shown below.

[0051] "Triggering conditions (before switching)"

[0052] ACC system control status: 1 (Under control)

[0053] Brake pedal operation amount: ≥1%

[0054] "Data Collection (Before Switching)"

[0055] The trigger conditions include the vehicle's latitude and longitude, speed, ACC system control status, and brake pedal operation amount 60 seconds prior to the trigger.

[0056] "Trigger Conditions (After Switching)"

[0057] ACC system control status: 1 (Under control)

[0058] Brake pedal operation amount: ≥1%

[0059] Workshop distance: ≤10m

[0060] "Collect data (after switching)"

[0061] The triggering conditions include the vehicle's latitude and longitude, speed, ACC system control status, brake pedal operation amount, presence of surrounding vehicles, and distance to surrounding vehicles 60 seconds prior to the triggering.

[0062] "Switch conditions and priorities"

[0063] Triggering condition A: High priority

[0064] Triggering condition B: Low priority

[0065] (2) When the vehicle side provides a switching instruction

[0066] When a switching instruction is received from the vehicle side, the vehicle device 4 switches the trigger conditions and collects a list of data. For example, before switching, the vehicle device 4 sends simple data such as the vehicle speed when the ACC system 22 is disconnected and user operations to the central device 2. When a switching instruction is received from the vehicle side, for example, due to a change in driving mode from normal mode to eco mode, the vehicle device 4 uses switching logic and, after switching, also sends data such as the presence or absence of surrounding vehicles to the central device 2. Examples of trigger condition IDs, collected data, switching conditions, and priorities are shown below.

[0067] "Trigger conditions (before switching)"

[0068] ACC system control status: 1 (Under control)

[0069] Brake pedal operation amount: ≥1%

[0070] "Data Collection (Before Switching)"

[0071] The trigger conditions include the vehicle's latitude and longitude, speed, ACC system control status, and brake pedal operation amount 60 seconds prior to the trigger.

[0072] "Trigger Conditions (After Switching)"

[0073] ACC system control status: 1 (Under control)

[0074] Brake pedal operation amount: ≥1%

[0075] Following distance: ≤10m

[0076] "Collect data (after switching)"

[0077] The triggering conditions include the vehicle's latitude and longitude, speed, ACC system control status, brake pedal operation amount, presence of surrounding vehicles, and distance to surrounding vehicles 60 seconds prior to the triggering.

[0078] "Switch conditions and priorities"

[0079] Triggering condition A: High priority

[0080] Triggering condition B: Low priority

[0081] like Figure 5 As shown, the trigger condition creation unit 6a creates a trigger condition file before the switch, thereby creating the trigger conditions before the switch. Figure 5 The example trigger condition file before switching includes trigger condition ID, trigger condition, ACC system control status, and brake pedal operation as items.

[0082] A summary of collected data is provided for the trigger conditions before creation and switching in section 6b. For example... Figure 6As shown, the data collection overview creation unit 6b creates a data collection overview file before the switch, thereby creating a data collection overview before the switch. Figure 6 The example file showing the data collected before the switchover includes the corresponding trigger condition ID, acquisition period (before the trigger condition is triggered), acquisition period (after the trigger condition is triggered), latitude and longitude, vehicle speed, control status of the ACC system, and brake pedal operation as items.

[0083] like Figure 7 As shown, the trigger condition creation unit 6a creates the switched trigger condition file, thereby creating the switched trigger conditions. Figure 7 The example of the switched trigger condition file in the example will include the trigger condition ID, trigger condition, ACC system control status, brake pedal operation amount, and vehicle distance as items.

[0084] A summary of collected data is provided for the trigger conditions created and switched in section 6b. For example... Figure 8 As shown, the data collection overview creation unit 6b creates a switched data collection overview file, thereby creating a switched data collection overview. Figure 8 The example file showing the collected data after the switch includes the corresponding trigger condition ID, acquisition period (before the trigger condition is triggered), acquisition period (after the trigger condition is triggered), latitude and longitude, vehicle speed, ACC system control status, brake pedal operation amount, presence or absence of surrounding vehicles, and distance between vehicles as items.

[0085] like Figure 9 As shown, the switching information creation unit 6c creates a switching condition and priority file, thereby creating the switching conditions and priorities. Figure 9 The example switching conditions and priority files will use the trigger condition ID and switching decision as items for the implemented trigger conditions. Priorities and switching decisions are set to avoid contradictions. If a contradiction occurs, priority is given over the switching decision; the trigger condition with the highest priority is determined, and then the trigger condition is switched according to the switching decision.

[0086] like Figure 10 As shown, in the vehicle device 4, the control unit 9, as its various functions, includes: a detection data acquisition unit 9a, a trigger condition determination unit 9b, a data collection creation unit 9c, and a data collection transmission unit 9d. Through these parts 9a to 9d, the data processing method of the vehicle device 4 is executed, and the data processing program of the vehicle device 4 is executed.

[0087] The detection data acquisition unit 9a acquires the detection data required for determining the trigger condition. For example, when determining the control state of the ACC system 22, the detection data acquisition unit 9a acquires data from the ACC system 22 showing the control state of the ACC system 22 as detection data.

[0088] The trigger condition determination unit 9b can switch the trigger conditions of the user object according to the switching conditions or priority. When the detection data acquisition unit 9a acquires detection data, it performs a trigger condition determination based on the acquired detection data. The data collection creation unit 9c can switch the data collection overview of the user object according to the switching conditions or priority, and create data collection based on the determination result of the trigger condition. When data collection is created by the data collection creation unit 9c, the data collection transmission unit 9d sends the created data collection from the communication unit 10 to the central device 2.

[0089] Next, refer to Figures 11 to 18 The function of the above-described structure will be explained. Here, the processing performed by the control unit 9 of the vehicle device 4 and the processing performed by the control unit 6 of the central device 2 will be explained regarding the switching instruction given by the central device 2 and the switching instruction given by the vehicle side.

[0090] (1) When the central device 2 issues a switching instruction

[0091] (1-1) Processing performed by the control unit 9 of the vehicle device 4 (refer to) Figures 11 to 12 )

[0092] In the vehicle device 4, the control unit 9 begins vehicle-side processing and waits to receive multiple trigger conditions, multiple data collection lists, switching conditions, and priorities from the central device 2. Upon receiving multiple trigger conditions, multiple data collection lists, switching conditions, and priorities distributed from the central device 2 via the communication unit 10, and upon acquiring these multiple trigger conditions, multiple data collection lists, switching conditions, and priorities from the central device 2 (A1), the control unit 9 saves the acquired multiple trigger conditions and multiple data collection lists in order to switch the trigger conditions and data collection lists (A2).

[0093] Control unit 9 determines the initial triggering condition, i.e., the triggering condition with the highest priority, as the triggering condition before the switch (A3), and acquires the detection data required to determine the triggering condition before the switch (A4, ...). Figure 14 S2, as shown, corresponds to the data acquisition step. Control unit 9 determines whether the trigger condition before the switch has been met (A5, Figure 14 S3, as shown, corresponds to the trigger condition determination step. When it is determined that the trigger condition determination before the switch has been met (A5: Yes), the control unit 6 creates the collection data (A6, corresponding to the collection data creation step), and sends the created collection data from the communication unit 10 to the central device 2 (A7, ...). Figure 14 S4, as shown, corresponds to the data collection and transmission step.

[0094] Control unit 9 is on standby to receive a handover instruction from central device 2. When communication unit 10 receives a handover instruction distributed from central device 2 and determines that a handover instruction from central device 2 has been received (A8: Yes), Figure 14 As shown in S5), the control unit 9 determines the trigger condition with the next lower priority as the trigger condition after the switch (A9), and acquires the detection data required to determine the determined trigger condition after the switch (A10, S5). Figure 14 S6, as shown, corresponds to the data acquisition step. Control unit 9 determines whether the trigger condition after the switch has been met (A11, Figure 14 S7, as shown, corresponds to the trigger condition determination step. When it is determined that the trigger condition after the switch has been met (A11: Yes), the control unit 6 creates collection data (A12, corresponding to the collection data creation step), and sends the created collection data from the communication unit 10 to the central device 2 (A13, ...). Figure 14 S8, as shown, is equivalent to the data collection and transmission step, which ends the vehicle-side processing.

[0095] For the above triggering conditions (before the switch), if the following condition is met:

[0096] ACC system control status: 1 (Under control)

[0097] Brake pedal operation amount: ≥1%

[0098] Then, the control unit 9 determines that the trigger condition determination before the switch has been met. That is, when the ACC system is under control, if the user performs a braking operation with a brake pedal operation amount of more than 1%, the control unit 9 determines that the trigger condition determination before the switch has been met. The control unit 9 collects data such as the latitude and longitude, vehicle speed, control status of the ACC system, and brake pedal operation amount 60 seconds before the trigger condition is triggered, and sends the collected data from the communication unit 10 to the central device 2.

[0099] When determining the switching instruction from central device 2, for the aforementioned triggering conditions (after switching), if the following condition is met:

[0100] ACC system control status: 1 (Under control)

[0101] Brake pedal operation amount: ≥1%

[0102] Workshop distance: ≤10m

[0103] Then, the control unit 9 determines that the trigger condition after the switch has been met. That is, if the ACC system is under control and the vehicle distance is less than 10m, and the user performs a braking operation with a brake pedal operation amount of more than 1%, the control unit 9 determines that the trigger condition after the switch has been met. The control unit 9 collects the latitude and longitude, vehicle speed, ACC system control status, brake pedal operation amount, presence of surrounding vehicles, and distance to surrounding vehicles from 60 seconds prior to the trigger condition, and sends the collected data from the communication unit 10 to the central device 2.

[0104] (1-2) Processing performed by the control unit 6 of the central device 2 (refer to) Figure 13 ).

[0105] In the central device 2, when the control unit 6 begins central-side processing, it creates multiple trigger conditions and multiple data collection lists (B1, equivalent to the trigger condition creation step and data collection list creation step), creates switching conditions and priorities (B2, equivalent to the switching information creation step), and distributes the multiple trigger conditions, multiple data collection lists, switching conditions, and priorities from the communication unit 7 to the vehicle device 4 (B3, ...). Figure 14 S1, as shown, corresponds to the distribution step, and the system waits to receive the collected data from the vehicle device 4. By receiving the collected data sent from the vehicle device 4 by the communication unit 10, the control unit 6 acquires the collected data from the vehicle device 4 (B4, corresponding to the collected data acquisition step).

[0106] When the switching conditions in the central device 2 are determined to be met (B5: Yes), the control unit 6 will distribute the switching instruction from the communication unit 7 to the vehicle device 4 (B6, Figure 17 As shown in S2), it waits to receive collected data from the vehicle device 4. Upon receiving the collected data from the vehicle device 4 via the communication unit 10, the control unit 6 acquires the collected data from the vehicle device 4 (B7, equivalent to the data acquisition step), ending the central processing. Afterward, by parsing the collected data acquired from the vehicle device 4, it is possible to analyze the scenarios in which the user is dissatisfied.

[0107] (2) When the vehicle side provides a switching instruction

[0108] (2-1) Processing performed by the control unit 9 of the vehicle device 4 (refer to) Figures 15 to 16 )

[0109] In the vehicle-use device 4, the control unit 9 performs the aforementioned steps A1 to A7 when starting vehicle-side processing. When it is determined that a switching instruction from the vehicle side has been received (A21: Yes), Figure 18 (As shown in S11), proceed with the above steps A9 to A13 to end the vehicle-side processing.

[0110] (2-2) Processing performed by the control unit 6 of the central device 2 (refer to) Figure 17 ).

[0111] In the central device 2, the control unit 6 performs the aforementioned steps B1 to B4 when starting central side processing. After the vehicle device 4 switches the trigger conditions and the data collection overview, the control unit 6 obtains the data collection data sent from the vehicle device 4 by receiving the data collection data sent from the vehicle device 4 through the communication unit 10 (B7, equivalent to the data collection acquisition step), and ends the central side processing.

[0112] The above examples illustrate the creation of both switching conditions and priorities, but it is also possible to create only either the switching conditions or priorities. Additionally, examples illustrate the switching of the trigger conditions for the object being used and the collection data overview, but it is also possible to switch only the trigger conditions for the object being used, or only the collection data overview for the object being used, based on either the switching conditions or priorities.

[0113] In a structure capable of switching only the trigger conditions of the user, in the central device 2, the trigger condition creation unit 6a creates multiple trigger conditions for detecting a specified scenario on the vehicle side. The data collection overview creation unit 6b creates a data collection overview corresponding to the multiple trigger conditions. The switching information creation unit 6c creates at least one of the switching conditions and priorities corresponding to each trigger condition. The distribution unit 6d distributes the multiple trigger conditions, the data collection overview, the switching conditions, and the priorities to the vehicle device 4. In the vehicle device 4, the trigger condition determination unit 9b can switch the trigger conditions of the user based on at least one of the switching conditions and priorities, and perform a trigger condition determination based on the detection data. The data collection creation unit 9c creates data collection based on the determination result of the trigger condition determination. Furthermore, the vehicle device 4 can adopt a structure that sends the switched trigger condition ID as a notification that the vehicle device 4 is the user trigger condition when a switch of the user trigger condition occurs to the central device 2, or it can adopt a structure that sends the user trigger condition ID along with the data collection to the central device 2.

[0114] In the configuration that allows switching only the collection data list of the user, in the central device 2, the trigger condition creation unit 6a creates trigger conditions for detecting a specified scenario on the vehicle side. The collection data list creation unit 6b creates multiple collection data lists corresponding to the trigger conditions. The switching information creation unit 6c creates at least one of a switching condition and a priority corresponding to each collection data list. The distribution unit 6d distributes the trigger conditions, multiple collection data lists, switching conditions, and priorities to the vehicle device 4 in at least one direction. In the vehicle device 4, the trigger condition determination unit 9b performs a trigger condition determination based on the detection data. The collection data creation unit 9c can switch the collection data list of the user according to at least one of the switching conditions and priorities, and create collection data based on the determination result of the trigger condition determination. In addition, the vehicle device 4 can be configured to send the ID of the switched collection data list as a notification of the collection data list for the vehicle device 4 when the collection data list of the user is switched, or it can be configured to send the collection data list ID of the user along with the collection data list when the collection data is sent to the central device 2.

[0115] As explained above, the following effects can be achieved according to the implementation method. In the central device 2, switching conditions and priorities are created corresponding to each trigger condition and each list of collected data. In the vehicle device 4, the trigger conditions and the list of collected data are switched according to the switching conditions and priorities. Collected data is created based on the determination result of the trigger condition and sent to the central device 2. Multiple trigger conditions used to detect scenarios where users have complaints can be switched arbitrarily, allowing for efficient improvement of vehicle functions.

[0116] The trigger conditions and collected data overview of the target device can be switched according to the switching instruction from the central device 2. The trigger conditions and collected data overview of the target device can be switched depending on the status of the central device 2.

[0117] The trigger conditions and collected data for switching the target application can be summarized based on the switching instructions from the vehicle side. This allows for switching of the trigger conditions and collected data for the target application depending on the vehicle-side conditions.

This disclosure also includes various modifications and variations within the same scope. Furthermore, various combinations and methods, including those with only one element, one or more elements, or fewer than one element, also fall within the scope and spirit of this disclosure.
