Description

The disclosed embodiments relate to a recording device, a recording system, a recording method, and a recording program.

2. Description of the Related Art Conventionally, drive recorders are known that are mounted on a vehicle and record images of the surroundings of the vehicle on a recording medium while the vehicle is running. Furthermore, some of these drive recorders are equipped with a parking monitoring function that records surrounding images even when the vehicle is parked.

For example, Patent Document 1 discloses a drive recorder that allows a user to select impact monitoring or normal monitoring as a parking monitoring function when the engine of the vehicle is turned off.

Impact monitoring is a mode in which recording is performed for a predetermined period of time only when the G (acceleration) sensor reacts. Hereinafter, this will be referred to as "event recording mode." Further, normal monitoring is a mode in which recording is performed for a predetermined period of time regardless of the reaction of the G sensor. Hereinafter, this will be referred to as "continuous recording mode."

Japanese Patent Application Publication No. 2018-016138

However, the above-mentioned conventional technology has room for further improvement in terms of suppressing the trouble of unnecessary video recording in the parking monitoring function and notification to the user.

Specifically, the event recording mode is a mode in which, in addition to collisions while the vehicle is parked, car break-ins and mischief are detected by the reaction of the G sensor and recorded. Therefore, in the event recording mode, the determination threshold of the G sensor is usually set lower than when the vehicle is running or in the above-mentioned constant recording mode. That is, the determination conditions are relaxed, and an impact is more easily detected in the event recording mode.

Therefore, when the event recording mode is used in the parking monitoring function, images are recorded even when the user opens or closes a door, and the user is notified of this each time, which can be troublesome.

One aspect of the embodiment has been made in view of the above, and provides a recording device, a recording system, and a recording system that are capable of suppressing the trouble of unnecessary video recording and notification to a user in a parking monitoring function. The purpose is to provide a recording method and recording program.

A recording device according to one aspect of the embodiment includes an imaging section, a video recording section, and a control section. The imaging unit is mounted on a vehicle and is provided to be able to capture an image of the surroundings of the vehicle. The video recording unit has a first mode in which the surrounding video is recorded and the user is notified when an acceleration exceeding a first threshold is detected, and a first mode in which the surrounding video is constantly recorded and the acceleration is greater than the first threshold. It has a second mode in which the acceleration is detected using a second threshold value. When operating the first mode as the vehicle transitions to the predetermined state, the control unit causes the video recording unit to operate in the second mode for a predetermined period after the vehicle transitions to the predetermined state. After operating, the first mode is operated. In addition, when the first mode is set to be on for operating the first mode when the vehicle transitions to the predetermined state, the control unit may be configured to set the second mode to be on or off. Regardless of whether the vehicle is in the predetermined state, the video recording section is operated in the second mode prior to the first mode.

According to one aspect of the embodiment, it is possible to suppress the trouble that a video is recorded unnecessarily in the parking monitoring function and the user is notified.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a recording device, a recording system, a recording method, and a recording program disclosed in the present application will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to the embodiments described below.

Moreover, below, the case where the recording device based on embodiment is the drive recorder 10 mounted in the vehicle C is mentioned as an example, and is demonstrated.

First, an overview of the recording method according to the embodiment will be explained using FIGS. 1A to 1E. 1A to 1E are schematic explanatory diagrams (Part 1) to (Part 5) of the recording method according to the embodiment.

As shown in FIG. 1A, the recording method according to the embodiment executes the parking monitoring function "when the ACC is off." The parking monitoring function includes an "event recording mode" and a "constant recording mode."

The "event recording mode" is a mode in which video is recorded for a predetermined set time only when the measured value of the G sensor shows a reaction exceeding the G threshold. Further, the "continuous recording mode" is a mode in which video is recorded for a predetermined set time regardless of the reaction of the G sensor.

Here, as shown in FIG. 1A, between the "event recording mode" and the "constant recording mode", the G threshold value is lower in the "event recording mode". That is, between the "event recording mode" and the "continuous recording mode", the determination condition for the G threshold value is relaxed in the "event recording mode", making it easier to detect an impact.

Note that the G threshold value for the "continuous recording mode" is provided for "event protection". "Event protection" protects video for a predetermined period before and after the time of detection of the impact from being overwritten and erased when an impact exceeding the G threshold is detected during the "continuous recording mode".

In addition, as shown in Figure 1A, the "event recording mode" is the "target" of user notification, and if a video is recorded in the "event recording mode" in the parking monitoring function, that fact will be notified to the user when the ACC is turned on. Be notified. On the other hand, the "continuous recording mode" is "not subject to" user notification, and the video recorded in the "continuous recording mode" in the parking monitoring function is not subject to notification to the user when the ACC is turned on.

The "event recording mode" and the "continuous recording mode" can be turned on or off by the user, for example, and in the parking monitoring function, the mode that is in the on state is executed.

Based on the above, first, basic operations when the event recording mode is on will be described using FIG. 1B. Note that, in order to make the explanation easier to understand, the on/off state of the continuous recording mode will not be mentioned here.

As shown in FIG. 1B, when the event recording mode is on, when the ACC is turned off, the constant recording during driving up to that point becomes "recording complete". Then, the drive recorder 10 shifts to the event recording mode as a parking monitoring function, and the drive recorder 10 enters the "event monitoring" state. The "event monitoring" state is a state in which the drive recorder 10 monitors only the reaction of the G sensor.

Each time there is an "impact detection" that exceeds the G threshold, the drive recorder 10 repeatedly performs "event recording" for a predetermined set time, and then returns to the "event monitoring" state.

When the ACC is turned on, the drive recorder 10 shifts to the driving mode and notifies the user that the event recording has been performed during the event recording mode.

Based on the basic operation when the event recording mode is on, next, the case where the constant recording mode is on will be described with reference to FIG. 1C. Note that FIG. 1C shows a recording method according to a comparative example.

If both event recording mode and continuous recording mode are set to on, as shown in Figure 1C, when ACC is turned off, the parking monitoring function first shifts to continuous recording mode, and then "continuous recording" is turned off. Recording continues for a predetermined set time ST (for example, about one hour) from when the vehicle was running, and then the recording is completed.

In addition, during the continuous recording mode, there is a high possibility that the user will open and close the door when exiting the vehicle after "ACC OFF", but as mentioned above, during the continuous recording mode, the G threshold is high and no impact will be detected. Therefore, as shown in FIG. 1C, such opening/closing of the door is "undetected".

Then, as a parking monitoring function, the drive recorder 10 shifts to an event recording mode, and the drive recorder 10 enters an "event monitoring" state. During the event recording mode in which such "event monitoring" is performed, the G threshold is low as described above, and impacts are easily detected.

Therefore, there is a possibility that the drive recorder 10 detects an impact caused by opening and closing the door when the user gets into the vehicle, at least before the ACC is turned on. If the door opening/closing during boarding is detected as an impact, "event recording" is performed, and according to the example shown in FIG. 1B, the user is notified that such "event recording" has been performed when "ACC is turned on". It is supposed to "notify".

However, if you are getting in the car, there is a high possibility that "ACC will be turned on" immediately after getting in the car. Therefore, in the recording method according to the comparative example, the user is not notified of "event recording" which does not reach the predetermined period CT immediately before "ACC ON". That is, "event recording" that is less than the predetermined period CT is canceled and is not recorded. Note that the predetermined period CT is, for example, approximately 1 to 2 minutes when the user opens and closes the door, gets into the vehicle, and then turns on the ACC.

As a result, according to the recording method according to the comparative example, when both the event recording mode and the continuous recording mode are set to ON, it is possible to suppress the troublesome situation in which video is recorded unnecessarily and the user is notified. can.

However, unlike the case in FIG. 1C, even if the event recording mode is on, there is a case where the constant recording mode is off. Such a case will be explained using FIG. 1D.

As shown in Figure 1D, when the event recording mode is on and the constant recording mode is off, when the ACC is turned off, the parking monitoring function will switch to the event recording mode, similar to the example in Figure 1B. The drive recorder 10 enters the "event monitoring" state.

As described above, since an impact is easily detected during the event recording mode, there is a high possibility that opening and closing of the door when exiting the vehicle after "ACC OFF" will be detected as an impact. If detected, "event recording" of the opening and closing of the door upon exiting the vehicle should be performed, as shown in FIG. 1D.

On the other hand, opening and closing the door while getting into the vehicle before "ACC ON" is likely to be detected as an impact as well, but as in the example in Figure 1C, if the "event recording" does not reach the predetermined period of CT, It is possible to cancel "event recording" and not notify the user.

However, in the example of FIG. 1D, even with the recording method according to the comparative example, the "event recording" of the opening and closing of the door at the time of exiting the vehicle cannot be canceled. Therefore, in such a case, when the ACC is turned on, unnecessary "event recording" corresponding to at least the opening and closing of the door at the time of getting off the vehicle, that is, "notification of the time to get off the vehicle" will occur.

Therefore, in the recording method according to the embodiment, when the event recording mode is on and the constant recording mode is off, the system is forcibly shifted to the constant recording mode for a predetermined period when the ACC is turned off.

Specifically, as shown in FIG. 1E, in the recording method according to the embodiment, when the event recording mode is on and the constant recording mode is off, when "ACC is turned off", the drive recorder 10 Even if the constant recording mode is off, the device is "forcibly" shifted to the constant recording mode for a predetermined period PT, and performs "continuous recording."

The predetermined period PT corresponds to the timing of getting off the vehicle after "ACC OFF" and is, for example, about several minutes. Thereby, it is possible to make it difficult to detect the impact caused by opening and closing the door when exiting the vehicle, which is likely to occur immediately after "ACC OFF" (see "Non-detection" in the figure).

Note that even if an impact exceeding the G threshold value is detected during the predetermined period PT, it will not be notified to the user because it will be "event protection" as described above.

Then, after the predetermined period PT has passed, the drive recorder 10 shifts to the event recording mode and enters the "event monitoring" state. Incidentally, even if an impact caused by opening and closing the door during boarding is detected, the "event recording" caused by this impact can be canceled, as in the example of FIG. 1C.

As a result, as shown in FIG. 1E, in the recording method according to the embodiment, when the event recording mode is on and the constant recording mode is off, at least for recording due to the impact of opening and closing the door, when "ACC is on" It is possible to "not notify" the user.

That is, according to the recording method according to the embodiment, when the event recording mode is on and the constant recording mode is off, it is possible to suppress the trouble of unnecessary recording of video and notification to the user. .

Note that if an impact that is not caused by opening or closing the door when exiting the vehicle is detected within the predetermined period of PT, the user will not be notified as described above, but because the event is protected, the user will not be able to check the video. It is possible.

Hereinafter, a configuration example of the drive recorder 10 to which the recording method according to the above-described embodiment is applied will be described in more detail.

FIG. 2 is a block diagram showing a configuration example of the drive recorder 10 according to the embodiment. Note that FIG. 2 shows only the constituent elements necessary for explaining the features of the embodiment, and the description of general constituent elements is omitted.

In other words, each component illustrated in FIG. 2 is functionally conceptual, and does not necessarily need to be physically configured as illustrated. For example, the specific form of distributing/integrating each block is not limited to what is shown in the diagram, and all or part of the blocks can be functionally or physically distributed/integrated in arbitrary units depending on various loads and usage conditions. It is possible to configure them in an integrated manner.

As shown in FIG. 2, the drive recorder 10 is mounted on a vehicle C. The vehicle C has a constant power source 2, an ACC 3, and an operation display section 4. ACC3 is a switch for the accessory power source of the vehicle C. The operation display unit 4 is a user interface device, and is realized by, for example, a touch panel display included in an in-vehicle device.

The drive recorder 10 is always connected to the power source 2. The drive recorder 10 also includes a camera 11, a G sensor 12, a storage section 13, and a control section 14. Note that the drive recorder 10 itself may have an input section for receiving various operations from the user and a display section for displaying various information, that is, a component corresponding to the operation display section 4 described above.

The camera 11 images a predetermined imaging area around the vehicle C. G sensor 12 measures acceleration.

The storage unit 13 is realized by, for example, a storage device such as a RAM (Random Access Memory) or a flash memory, and in the example of FIG. 2, stores setting information 13a and a recorded video group 13b.

The setting information 13a is information regarding various settings of the parking monitoring function that operates when the ACC is turned off. Here, a specific example of this setting information 13a will be explained. FIG. 3 is a diagram showing a specific example of the setting information 13a according to the embodiment.

In the example of FIG. 3, the setting information 13a has contents in which control details for mode transition in the parking monitoring function are set for each on/off combination of the event recording mode and the constant recording mode.

In the setting example shown in FIG. 3, for example, if both event recording mode and continuous recording mode are "on", when ACC is turned off, the mode first shifts to continuous recording mode, "continuous recording" is performed for one hour, and then , the mode transition in the parking monitoring function is controlled so that "event monitoring" is performed by shifting to the event recording mode.

Also, for example, if the event recording mode is "on" and the continuous recording mode is "off", when the ACC is turned off, the mode will first shift to the continuous recording mode, "forced continuous recording" will be performed for one minute, and then the event The mode transition in the parking monitoring function is controlled so that "event monitoring" is performed by shifting to the recording mode. Note that this case corresponds to the recording method according to the embodiment.

Also, for example, if the event recording mode is "off" and the continuous recording mode is "on", when the ACC is turned off, the mode will shift to the continuous recording mode and the "constant recording" will be performed for only one hour, for example. Mode transition in the hour monitoring function is controlled. Note that in such a case, the transition to event recording mode is not performed.

Further, for example, if both the event recording mode and the constant recording mode are "off", the parking monitoring function does not operate when the ACC is turned off. That is, neither the transition to the event recording mode nor the transition to the constant recording mode is performed, and control is performed so that "no recording is performed when parking".

The on/off of the event recording mode and the continuous recording mode in the setting information 13a, and the setting time ST indicated as 1 hour for "continuous recording" can be set by the user via the operation display section 4, etc. described above. It is.

However, the underlined predetermined period PT of 1 minute in "Forced continuous recording" in FIG. It is preferable to do so. Therefore, for example, the settings may be made by downloading from a server device of a data center that manages various programs etc. that operate on the vehicle C. Note that such an example will be described later in the explanation using FIG. 6.

Further, the setting information 13a includes information indicating the on/off state being set in each of the event recording mode and the constant recording mode, as shown as check boxes in the example of FIG.

Returning to the explanation of FIG. 2, the recorded video group 13b will be explained next. The recorded video group 13b stores each recorded video recorded by a video recording unit 14b, which will be described later.

The control unit 14 is a controller, and for example, various programs stored in the storage device inside the drive recorder 10 use the RAM as a work area by a CPU (Central Processing Unit), MPU (Micro Processing Unit), etc. This is achieved through execution. Further, the control unit 14 can be realized by, for example, an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

As shown in FIG. 2, the control section 14 includes a mode control section 14a, a video recording section 14b, and a notification section 14c, and realizes or executes information processing functions and operations described below.

The mode control unit 14a acquires the on/off change of the ACC3, and when the ACC3 turns from on to off, the video recording unit in the parking monitoring function uses the on/off state of each mode set in the setting information 13a to 14b mode transition is controlled. Moreover, the mode control unit 14a shifts the video recording unit 14b to the running mode when the ACC3 is turned off→on.

The video recording unit 14b records the captured video of the camera 11 in the recorded video group 13b according to the operation mode while switching the operation mode based on the control of the mode control unit 14a. The video recording section 14b includes a first mode operating section 14ba and a second mode operating section 14bb.

The first mode operating unit 14ba performs an operation corresponding to the event recording mode in the parking monitoring function. That is, the first mode operating unit 14ba monitors the G sensor 12, and executes "event recording" when receiving an input of a measured value of the G sensor 12 that exceeds the G threshold.

The second mode operation unit 14bb performs an operation corresponding to the constant recording mode in the parking monitoring function. That is, when the ACC3 is turned off, the second mode operation unit 14bb executes "constant recording" for the set time ST if the constant recording mode is on. Further, when the ACC3 is turned off, the second mode operation unit 14bb executes "constant recording" for a predetermined period PT if the event recording mode is on, even if the constant recording mode is off.

The notification unit 14c notifies the operation display unit 4 of the recorded video stored in the recorded video group 13b by the video recording unit 14b in the event recording mode of the parking monitoring function.

Next, the processing procedure executed by the drive recorder 10 according to the embodiment will be described using FIGS. 4 and 5. 4 and 5 are flowcharts (Part 1) and (Part 2) showing the processing procedure executed by the drive recorder 10 according to the embodiment. It is assumed that at the "start" point in FIG. 4, the ACC 3 is on, the vehicle C is running, and the drive recorder 10 is operating in the running mode.

First, the mode control unit 14a determines whether ACC3 is turned off (step S101). Here, if ACC3 remains on (step S101, No), step S101 is repeated.

Moreover, when ACC3 is turned off (step S101, Yes), the mode control unit 14a refers to the setting information 13a and determines whether the event recording mode is on (step S102). Here, if the event recording mode is on (step S102, Yes), then the mode control unit 14a determines whether the constant recording mode is on (step S103).

If the constant recording mode is on (step S103, Yes), the mode control unit 14a shifts the video recording unit 14b to the constant recording mode (step S104). In the constant recording mode, the second mode operating section 14bb of the video recording section 14b performs "constant recording."

During such "constant recording", it is determined whether ACC3 is turned on (step S105). Here, if ACC3 is not turned on (step S105, No), it is then determined whether the set time ST has elapsed (step S106). Here, if the set time ST has not elapsed (step S106, No), the process is repeated from step S105.

On the other hand, if the constant recording mode is not on in step S103 (step S103, No), the mode control unit 14a forcibly shifts the video recording unit 14b to the constant recording mode (step S107). That is, the second mode operating section 14bb of the video recording section 14b performs "constant recording."

During such forced "constant recording", it is determined whether ACC3 is turned on (step S108). Here, if ACC3 is not turned on (step S108, No), it is then determined whether a predetermined period PT has elapsed (step S109). Here, if the predetermined period PT has not elapsed (step S109, No), the process is repeated from step S108.

Then, if the set time ST has elapsed in step S106 (step S106, Yes), or if the predetermined period PT has elapsed in step S109 (step S109, Yes), the mode control unit 14a causes the video recording unit 14b to perform event recording. mode (step S110).

In the event recording mode, the first mode operation section 14ba of the video recording section 14b enters the "event monitoring" state (step S111). Then, if the G sensor 12 detects an acceleration exceeding the G threshold in the event recording mode, the first mode operation unit 14ba performs "event recording".

Then, during the event recording mode, it is determined whether ACC3 is turned on (step S112). Here, if ACC3 is not turned on (step S112, No), the process is repeated from step S111.

On the other hand, if ACC3 is turned on in steps S105, S108, and S112 (step S105, Yes/step S108, Yes/step S112, Yes), the mode control unit 14a shifts the video recording unit 14b to the running mode. (step S113), and repeats the processing from step S101.

Note that if the event recording mode is not on in step S102 (step S102, No), the mode control unit 14a determines whether the constant recording mode is on as shown in FIG. 5 (step S114). ).

If the constant recording mode is on (step S114, Yes), the mode control section 14a shifts the video recording section 14b to the constant recording mode (step S115). That is, the second mode operating section 14bb of the video recording section 14b performs "constant recording."

During such "constant recording", it is determined whether ACC3 is turned on (step S116). Here, if ACC3 is not turned on (step S116, No), it is then determined whether the set time ST has elapsed (step S117). Here, if the set time ST has not elapsed (step S117, No), the process is repeated from step S116.

Then, if the set time ST has elapsed in step S117 (step S117, Yes), or if the constant recording mode is not on in step S114 (step S114, No), it is determined whether ACC3 is turned on (step S117, Yes). S118). Here, if ACC3 is not turned on (step S118, No), step S118 is repeated.

On the other hand, if ACC3 is turned on in steps S116 and S118 (step S116, Yes/step S118, Yes), the mode control unit 14a shifts the video recording unit 14b to the running mode (step S119), and as shown in FIG. The process from Step S101 in Step 4 will be repeated.

By the way, although the outline has already been described, the settings such as the various programs that operate on the drive recorder 10 and the predetermined period PT may be rewritten by downloading data from the data center 100, for example. A recording system 1 according to an embodiment that achieves this will be described using FIG. 6. FIG. 6 is a diagram showing a configuration example of the recording system 1 according to the embodiment.

As shown in FIG. 6, the recording system 1 includes drive recorders 10 each mounted on one or more vehicles C, and a server device 101. The server device 101 is a distribution server device operated by the data center 100 that manages various programs that operate on the vehicle C.

The vehicle C or the drive recorder 10 has a communication interface (not shown) and is provided to be able to communicate wirelessly with the server device 101 via the network N. The network N is, for example, the Internet or a mobile phone network.

The server device 101 "data distributes" update data via the network N when there is a need to update settings such as various programs running on the drive recorder 10 or predetermined period PT.

The drive recorder 10 acquires the distributed update data, and if there is such update data at the time of startup when the ACC3 is turned on, for example, the drive recorder 10 shifts to the reprogramming mode and rewrites the data. . Note that the user may be notified that update data is available, and the data may be rewritten by the user's operation.

By configuring such a recording system 1, for example, it becomes possible to easily and manageably rewrite data in the drive recorders 10 installed in a large number of commercial vehicles owned by a business operator.

As described above, the drive recorder 10 according to the embodiment (corresponding to an example of a "recording device") includes a camera 11 (corresponding to an example of an "imaging section"), a video recording section 14b, and a control section 14. Be prepared. The camera 11 is mounted on the vehicle C and is provided to be able to capture images of the surroundings of the vehicle C. The video recording unit 14b operates in an event recording mode (corresponding to an example of a “first mode”) in which the video recording unit records surrounding video and notifies the user when acceleration exceeding a predetermined threshold is detected; It has a constant recording mode (corresponding to an example of a "second mode") in which surrounding images are always recorded. When operating the event recording mode as the vehicle C transitions to the predetermined state, the control section 14 causes the video recording section 14b to operate in the constant recording mode for a predetermined period PT after the vehicle C shifts to the predetermined state. After that, activate event recording mode.

Therefore, according to the drive recorder 10 according to the embodiment, when the vehicle C shifts to a predetermined state, for example, when the ACC 3 is turned off, it is possible to suppress the trouble that a video is recorded unnecessarily and the user is notified. .

Further, the control unit 14 operates the event recording mode when the vehicle C transitions to a predetermined state, and when the event recording mode is set on, the control unit 14 determines whether the constant recording mode is set on or off. Regardless, once the vehicle C has transitioned to a predetermined state, the video recording unit 14b is operated in the constant recording mode prior to the event recording mode.

Therefore, according to the drive recorder 10 according to the embodiment, even if the event recording mode is on, the constant recording mode is off, and the settings are such that it is easy to detect an impact, the drive recorder 10 is useless due to, for example, opening and closing the door when getting off the vehicle. It is possible to prevent a video from being recorded and being notified to the user.

Further, the above-mentioned predetermined state of the vehicle C is a state in which the accessory power source of the vehicle C is turned off.

Therefore, according to the drive recorder 10 according to the embodiment, in the parking monitoring function after the ACC 3 is turned off, it is possible to suppress the trouble that a video is recorded unnecessarily and the user is notified.

Further, the recording system 1 according to the embodiment includes a drive recorder 10 and a server device 101. The server device 101 is provided to be able to communicate with one or more drive recorders 10, and distributes update data including setting information regarding the event recording mode and the constant recording mode to each of the drive recorders 10.

Therefore, according to the recording system 1 according to the embodiment, for example, it is possible to easily rewrite the setting information of the drive recorder 10 installed in a large number of commercial vehicles owned by a business operator, especially parameters that are not subject to user settings. Moreover, it can be easily managed.

In the above-described embodiment, the event recording mode is an example in which event recording is performed when an impact is detected. You may go.

Further advantages and modifications can be easily deduced by those skilled in the art. Therefore, the broader aspects of the invention are not limited to the specific details and representative embodiments shown and described above. Accordingly, various changes may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
