[0009] Hereinafter, an embodiment of a drive recorder and a control method thereof will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to the following embodiment.

[0010] 1 is a schematic diagram of a drive recorder and a control method according to an embodiment. The drive recorder 1 according to the embodiment is a device that records images captured by an in-vehicle camera. The drive recorder 1 records images captured by, for example, a front camera, a side camera, a rear camera, and an in-vehicle camera (hereinafter, referred to as "in-vehicle camera images").

[0011] As a result, when a traffic accident occurs, the drive recorder 1 can play back the recorded video, thereby contributing to the analysis of the situation at the time of the accident and the elucidation of the cause of the accident.

[0012] Furthermore, the drive recorder 1 has a function of prohibiting the recording of vehicle-mounted camera footage for users who do not wish to record vehicle-mounted camera footage from the viewpoint of privacy protection, etc. By using this function, the user can set each vehicle-mounted camera to permit or prohibit the recording of vehicle-mounted camera footage (hereinafter, referred to as "user setting").

[0013] In the present disclosure, the drive recorder 1 has a configuration that can suppress the occurrence of a situation in which it is not possible to record vehicle-mounted camera video, such as when a user intentionally sets a user setting to prohibit the recording of vehicle-mounted camera video. Specifically, as shown in Fig. 1, when the drive recorder 1 is started, it acquires a user setting regarding permission and prohibition of recording of vehicle-mounted camera video, and displays the contents of the user setting on the display operation device 11.

[0014] In the example shown in FIG. 1, the functions for recording vehicle camera images from the front camera, side camera, and interior camera are set to ON, and the function for recording vehicle camera images from the rear camera is set to OFF.

[0015] In this way, when at least one vehicle-mounted camera is prohibited from recording video, the drive recorder 1 notifies the user of a message alerting the user to the user's settings. Furthermore, the drive recorder 1 suggests to the user that the user change the settings to more desirable settings than the user's settings. For example, the drive recorder 1 outputs a voice message saying, "The rear camera is turned off. Since rear-end collisions are occurring frequently, why don't you change the setting to record rear-end video only when there is a strong impact?"

[0016] This allows the drive recorder 1 to prompt the user to change the setting to turn on the function for recording the vehicle-mounted camera video of the rear camera, thereby preventing the occurrence of a situation in which the vehicle-mounted camera video cannot be recorded. As a result, for example, when a traffic accident occurs, it is possible to avoid trouble caused by the vehicle-mounted camera video not being recorded in the drive recorder 1.

[0017] Thereafter, when the drive recorder 1 recognizes a user's voice indicating approval, such as "yes," in response to a proposal to the user, it changes the setting to turn on the function of recording the vehicle-mounted camera image of the rear camera.

[0018] Furthermore, the drive recorder 1 displays a permission button 11A for permitting a change to the user settings and a prohibition button 11B for prohibiting a change to the user settings on the display operation device 11. Then, when the drive recorder 1 receives an operation of the permission button 11A by the user, the drive recorder 1 changes the setting to turn on the function for recording the vehicle-mounted camera video of the rear camera.

[0019] Furthermore, when the drive recorder 1 accepts the operation of the prohibition button 11B by the user, the drive recorder 1 maintains the user setting without changing it. In other words, the drive recorder 1 maintains the setting of not recording the vehicle-mounted camera video of the rear camera. Hereinafter, the configuration and operation of the drive recorder 1 will be described in detail with reference to Figs. 2 to 7.

[0020] Fig. 2 is a block diagram showing an example of the configuration of a drive recorder 1 according to an embodiment. As shown in Fig. 2, the drive recorder 1 is connected to a server device 101 via a communication network 100 such as the Internet so as to be capable of wireless communication. The functions of the server device 101 will be described later.

[0021] The drive recorder 1 includes a display operation device 11 , a front camera 12 , a side camera 13 , a rear camera 14 , an in-vehicle camera 15 , a speaker 16 , a microphone 17 , an acceleration sensor 18 , a memory unit 2 , and a controller 3 .

[0022] The display operation device 11 is, for example, a touch panel display. The display operation device 11 displays images of the vehicle-mounted camera video input from the controller 3, user setting information related to each vehicle-mounted camera, the permission button 11A, the prohibition button 11B, and the like. The display operation device 11 also accepts user operations on the permission button 11A and the prohibition button 11B, and outputs an operation signal corresponding to the operation to the controller 3.

[0023] The front camera 12 is an imaging device that captures an image in front of the vehicle. The front camera 12 outputs the captured in-vehicle camera image to the controller 3. The side camera 13 is an imaging device that captures an image on the side of the vehicle. The side camera 13 outputs the captured in-vehicle camera image to the controller 3.

[0024] The rear camera 14 is an imaging device that captures an image of the rear of the vehicle. The rear camera 14 outputs the captured in-vehicle camera image to the controller 3. The interior camera 15 is an imaging device that captures an image of the interior of the vehicle. The interior camera 15 outputs the captured in-vehicle camera image to the controller 3.

[0025] The speaker 16 outputs various types of audio information input from the controller 3. The speaker 16 outputs, for example, the above-mentioned audio message "The rear camera is turned off. Since rear-end collisions are occurring frequently, would you like to set it so that rear-end video images are recorded only when there is a strong impact?"

[0026] The microphone 17 picks up sounds within the vehicle cabin and outputs the sounds to the controller 3. The microphone 17 picks up sounds uttered by the user, such as the above-mentioned "yes," and outputs the sounds to the controller 3. The acceleration sensor 18 is a G sensor that detects the acceleration of the vehicle and outputs the detected acceleration to the controller 3. The acceleration sensor 18 detects, for example, acceleration caused in the vehicle by accelerator operation and brake operation, and acceleration caused in the vehicle by a collision or the like, and outputs the detected acceleration to the controller 3.

[0027] The storage unit 2 is, for example, an information storage device such as a data flash, and stores user setting information 21, safe driving diagnosis information 22, system speech information 23, video / audio information 24, and notification suggestion count information 25, and the like.

[0028] Fig. 3 is an explanatory diagram of user setting information 21 according to the embodiment. As shown in Fig. 3, the user setting information 21 is information in which a setting for permitting or prohibiting recording of vehicle-mounted camera video, set by a user, is associated with each vehicle-mounted camera.

[0029] In the example shown in Fig. 3, the vehicle camera image of the front camera 12 is set to be recorded. Also, the vehicle camera image of the side camera 13 is set to be recorded. Also, the vehicle camera image of the rear camera 14 is set not to be recorded. Also, the vehicle camera image of the interior camera 15 is set not to be recorded.

[0030] The setting of not recording the on-board camera video here is a setting of deleting the captured on-board camera video. Note that the setting of not recording the on-board camera video may be a setting of not allowing the on-board camera to capture the on-board camera video, or may be a setting of turning off the on-board camera.

[0031] 4 is an explanatory diagram of the safe driving diagnosis information 22 according to the embodiment. As shown in FIG 4, the safe driving diagnosis information 22 is information in which various diagnosis items in the driving operation of the vehicle are associated with diagnosis results (scores).

[0032] The score is an index showing how the user's driving operation contributes to safe driving, and the higher the score, the more the user's driving operation contributes to safe driving. Note that, as an example, the maximum score is set to 100 here.

[0033] The traffic signal obedience score is increased each time the user obeys a traffic signal and is limited each time the user ignores a traffic signal. The sudden acceleration score is decreased each time the user performs a sudden acceleration operation and is increased each time the user performs a gentle acceleration operation.

[0034] The score for sudden braking is deducted each time the user performs a sudden braking operation and is increased each time the user performs a gentle braking operation. The score for inattentive driving is deducted each time the user performs inattentive driving and is increased each time the user focuses on the direction in which the vehicle is traveling.

[0035] For example, the score for backing up is lower the more times the driver turns around while backing up, and higher the score is, and the fewer times the driver turns around while backing up. Note that the diagnosis items shown in Fig. 4 are just an example, and there are various diagnosis items such as reckless overtaking and maintaining a safe distance between vehicles.

[0036] Fig. 5 is an explanatory diagram of the system utterance information 23 according to the embodiment. As shown in Fig. 5, the system utterance information 23 is information in which an in-vehicle camera for which recording of the in-vehicle camera video is prohibited by user settings is associated with information on a voice message to be notified and proposed to the user at that time.

[0037] For example, if the rear camera 14 is prohibited from recording, the user settings are associated with a voice message saying, "The rear camera is turned off. Since rear-end collisions are occurring frequently, would you like to set it to record rear-end footage only in the event of a strong impact?"

[0038] In addition, if the in-vehicle camera 15 is prohibited from recording, the user settings are associated with a voice message stating, "The in-vehicle camera is OFF. Since there are blind spots with the front and rear cameras, would you like to set it to record interior footage only in the event of a strong impact?"

[0039] In addition, when the side camera 13 is prohibited from recording, the user settings are associated with a voice message saying, "The side camera is OFF. There are cases where it is difficult to detect an impact, such as a side scraping accident. Would you like to set it to record side images?"

[0040] Fig. 6 is an explanatory diagram of video / audio information 24 according to an embodiment. As shown in Fig. 6, the video / audio information 24 is information in which the recording date and time of the video and audio are associated with each vehicle-mounted camera, and video / audio data including the vehicle-mounted camera video and the audio when the vehicle-mounted camera video was captured.

[0041] For example, in the case of the user settings shown in Figure 3, as shown in Figure 6, the recording date and time and video and audio data are recorded for the front camera 12 and the side camera 13, but the recording date and time and video and audio data are not recorded for the rear camera 14 and the in-vehicle camera 15.

[0042] The notification suggestion count information 25 is information indicating the cumulative number of notifications and suggestions of the same content made to the user. Every time the drive recorder 1 is started, it acquires user setting information, and if there is an in-vehicle camera that is prohibited from recording the in-vehicle camera video, it outputs a notification suggestion message (see FIG. 5) corresponding to the in-vehicle camera, and increments the cumulative number of notification suggestion messages by one.

[0043] The controller 3 includes a microcomputer having a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), etc., and various circuits. The controller 3 controls the operation of the drive recorder 1 by the CPU executing a control program stored in the ROM using the RAM as a working area. The control program may be stored in a storage device from the outside via a communication line, etc.

[0044] The controller 3 may be configured in part or in whole using hardware such as an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA).

[0045] When the controller 3 is started, it first obtains the user setting information 21. If the user setting information 21 includes an in-vehicle camera for which recording of in-vehicle camera video is prohibited, the controller 3 notifies the user of a message calling attention to the current user settings.

[0046] Furthermore, the controller 3 suggests to the user that the settings be changed to more desirable settings than the current user settings. Specifically, the controller 3 notifies the user of a warning message regarding the user settings and suggests to the user that the settings be changed to more desirable settings than the current user settings by outputting a notification suggestion message shown in Fig. 5 from the speaker 16. Then, the controller 3 adds 1 to the cumulative number of times that the notification suggestion message has been output this time.

[0047] In this way, the controller 3 notifies the user of warning messages regarding the user settings and suggests changes to the current user settings to more desirable settings by voice, so that the information can be conveyed to the user more reliably than when the notifications and suggestions are made by screen display.

[0048] Thereafter, when the controller 3 recognizes a user's speech permitting a change to the desired setting, or when the controller 3 receives an operation for changing to the desired setting, the controller 3 changes the current user setting to the desired setting.

[0049] For example, when the controller 3 recognizes the user's utterance of "Yes," the controller 3 changes the current user setting to a desired setting. Also, when a signal indicating that the permission button 11A (see FIG. 1) has been operated is input from the display operation device 11, the controller 3 changes the current user setting to a desired setting.

[0050] At this time, the controller 3 may be configured to notify the user of the changed settings by voice. For example, the controller 3 outputs a voice message saying, "The rear camera can now record only when a strong impact occurs." In this way, the controller 3 can reliably make the user aware that the settings of the in-vehicle camera have been changed.

[0051] In this way, the controller 3 changes the current user settings to desirable settings only when the user permits the change of the user settings, thereby making it possible to prevent the user settings from being changed against the user's will.

[0052] In addition, the controller 3 maintains the current user settings when it recognizes a user utterance that does not permit a change to the desired settings, when it does not recognize a user utterance that permits a change to the desired settings within a certain period of time, or when the vehicle starts moving.

[0053] For example, when the controller 3 recognizes the user's utterance of "No," the controller 3 maintains the current user settings. Also, when the controller 3 does not recognize an utterance indicating consent, such as "Yes," within 10 seconds after the controller 3 notifies the user of a warning message regarding the user settings and proposes a change to settings that are more desirable than the current user settings, the controller 3 maintains the current user settings.

[0054] In this way, the controller 3 maintains the current user settings when the user clearly refuses to change the user settings, when the user ignores the proposal from the controller 3, or when the user starts the vehicle ignoring the proposal from the controller 3. In this way, the controller 3 can prevent the user settings from being changed against the user's will.

[0055] Furthermore, before notifying the user of a warning message regarding the user settings and proposing a change to a more desirable setting than the current user settings, the controller 3 refers to the notification proposal count information 25. When the cumulative number of notifications and proposals having the same content as the notification and proposal to be made has reached a predetermined number (e.g., three times), the controller 3 stops notifying the user of a warning message regarding the user settings and stopping the proposal to change to a more desirable setting than the current user settings.

[0056] This makes it possible for the controller 3 to prevent the user from feeling annoyed when the controller 3 repeatedly suggests the same desirable settings even when the user has no intention of changing the user settings.

[0057] At this time, the controller 3 may be configured to output a voice message such as, for example, "The recording settings for the vehicle-mounted camera images can be changed at any time from the setting screen, so please consider doing so." This allows the controller 3 to gently prompt the user to change the user settings to desirable settings.

[0058] The controller 3 may also be configured to have an image recognition function and determine the tendency of the user's driving operation by image recognition from an in-vehicle camera image. In this case, the controller 3 generates safe driving diagnosis information 22 (see FIG. 4) based on the determination of the tendency of the user's driving operation.

[0059] The controller 3 may be configured to generate the safe driving diagnosis information 22 using the detection result of the acceleration input from the acceleration sensor 18 in addition to the in-vehicle camera image. This allows the controller 3 to more accurately perform a safe driving diagnosis for sudden acceleration and sudden braking in addition to following traffic signals, looking away from the driver, and backing up. The controller 3 then suggests to the user a change to a desirable setting according to the determined driving operation tendency of the user, that is, the diagnosis result of the safe driving diagnosis.

[0060] For example, the controller 3 may be configured to suggest to the user that the settings be changed to record the on-board camera image of the rear camera 14 if the user whose diagnosis result for backing up is less than a predetermined score (80) has prohibited recording of the on-board camera image of the rear camera 14.

[0061] Furthermore, even if the user setting prohibits recording of the vehicle-mounted camera image of the rear camera 14, if the diagnosis result of backing up is equal to or higher than a predetermined score (80), the controller 3 may be configured not to suggest a change to the setting to record the vehicle-mounted camera image of the rear camera 14. This allows the controller 3 to reduce the number of times that unnecessary changes to the user setting are suggested to the user.

[0062] In addition, the controller 3 may be configured to transmit vehicle-mounted camera footage to a server device 101 that determines the user's driving tendencies from the vehicle-mounted camera footage, that is, to a server device 101 that generates safe driving diagnosis information 22 for the user from the vehicle-mounted camera footage.

[0063] In this case, the controller 3 receives information on the tendency of the user's driving operation, that is, the safe driving diagnosis information 22, from the server device 101, and stores it in the storage unit 2. Then, the controller 3 suggests to the user a change to a desirable setting according to the tendency of the user's driving operation. This allows the controller 3 to suggest to the user a change to a desirable setting according to the safe driving diagnosis information 22 without generating the safe driving diagnosis information 22, thereby reducing the processing load.

[0064] In addition, the controller 3 notifies the user of a warning message regarding the settings and suggests changes to desirable settings for each of the front camera 12, the side camera 13, the rear camera 14, and the in-vehicle camera 15. This allows the controller 3 to set various combinations of permission and prohibition of recording of vehicle-mounted camera footage in accordance with the user's needs.

[0065] In addition, when the controller 3 determines the settings for permitting and prohibiting recording of vehicle camera footage for each vehicle camera, it stores the vehicle camera footage captured by the vehicle camera for which recording is permitted, and the audio at that time, in the memory unit 2 as video / audio information 24.

[0066] Next, an example of processing executed by the controller 3 of the drive recorder 1 according to the embodiment will be described with reference to Fig. 7. Fig. 7 is a flowchart showing an example of processing executed by the controller 3 of the drive recorder 1 according to the embodiment. Note that, here, processing related to permission and prohibition of recording of vehicle-mounted camera video will be described, and other processing executed by a general drive recorder 1 will not be described.

[0067] When the controller 3 is started, it starts the process shown in Fig. 7. Specifically, as shown in Fig. 7, the controller 3 first acquires the user setting information 21 (step S101). Next, the controller 3 determines whether or not there is an in-vehicle camera for which recording of the in-vehicle camera video is prohibited in the user setting information 21 (step S102).

[0068] When the controller 3 determines that there is no in-vehicle camera with recording prohibited (step S102, No), the process ends. When the controller 3 determines that there is an in-vehicle camera with recording prohibited (step S102, Yes), the controller 3 acquires the notification proposal count information 25 (step S103).

[0069] Then, the controller 3 determines whether the cumulative number of notification suggestion messages associated with the recording-prohibited in-vehicle camera in the notification suggestion number information 25 is equal to or greater than a predetermined number (step S104). When the controller 3 determines that the cumulative number is equal to or greater than the predetermined number (step S104, Yes), the controller 3 ends the process.

[0070] When the controller 3 determines that the cumulative number is less than the predetermined number, that is, the cumulative number is not equal to or greater than the predetermined number (step S104, No), the controller 3 acquires the safe driving diagnosis information 22 (step S105). Then, the controller 3 notifies the user of a warning message regarding the current user settings (step S106).

[0071] Furthermore, the controller 3 proposes to the user a change to a desirable setting according to the safe driving diagnosis information 22, that is, according to the user's driving operation tendency (step S107). After that, the controller 3 determines whether or not a setting change condition is satisfied (step S108).

[0072] The setting change condition is, for example, to recognize a user's utterance that consents to a change to a desirable setting, or to accept an operation to change to a desirable setting. When the controller 3 determines that the setting change condition is satisfied (step S108, Yes), the controller 3 changes the user setting to the proposed desirable setting (step S109) and ends the process.

[0073] If the controller 3 determines that the setting change condition is not satisfied (step S108, No), the controller 3 determines whether or not the setting maintenance condition is satisfied (step S110). The setting maintenance condition is, for example, that the controller 3 recognizes a user's utterance that does not permit a change to a desirable setting, that the controller 3 does not recognize a user's utterance that permits a change to a desirable setting within a certain period of time, or that the vehicle has started traveling.

[0074] When the controller 3 determines that the setting maintenance condition is not satisfied (step S110, No), the controller 3 moves the process to step S108. When the controller 3 determines that the setting maintenance condition is satisfied (step S110, Yes), the controller 3 ends the process without changing the current user settings.

[0075] In the above-described embodiment, a case was described in which the recording of on-board camera footage is prompted when recording of on-board camera footage is prohibited, but the recording of on-board camera footage may also be prompted when recording of on-board camera footage is permitted.

[0076] For example, when the storage capacity of the storage unit 2 falls below a predetermined capacity, the controller 3 may prompt the user to prohibit the recording of on-board camera footage by an on-board camera that is permitted to record on-board camera footage.

[0077] The controller 3 may be configured to recognize an image of the driver of the vehicle and store the image. In this case, the controller 3 stores notification proposal count information 25 for each driver. This prevents the controller from making unnecessary notifications and proposals to the same driver more than a predetermined number of times, and allows the controller to make appropriate notifications and proposals to drivers whose cumulative number of notifications and proposals is less than a predetermined number.
