Description

The present invention relates to a drive recorder.

A drive recorder is a device that uses a camera installed in a vehicle to capture a scene outside the vehicle or inside the vehicle and records it as moving image data on a storage medium such as a memory card. Since the video data is used for verification of an accident encountered by the vehicle while driving, the video data is continuously recorded from the start of the engine to the stop of the engine. Such a function of continuously recording regardless of the occurrence of a specific event is called continuous recording. When the capacity of the memory card reaches the upper limit, the constantly recorded video data is overwritten by the new video data, and the previous video data is deleted.

In addition, the drive recorder has an event recording function that extracts and records short-time video data before and after the accident when an impact exceeding the threshold value is applied to the main body of the drive recorder due to an accident while driving. .. The video data of the event recording is distinguished from the video data of the constant recording, and is stored in different folders. The video data recorded at the event is not overwritten by the video data recorded at all times.

Such a drive recorder has a parking mode function that records moving image data even while the vehicle engine is stopped in order to monitor vandalism on the vehicle. Even in the parking mode, there is a continuous recording function and an event recording function. The constantly recorded video data in the parking mode is also overwritten by the new video data when the capacity in the memory card reaches the upper limit. However, the video data recorded at the event is not overwritten by the video data recorded at all times.

JP-A-2019-164846

Even if an accident or the like is encountered, if the impact is small and below the threshold value, the event will not be recorded and only the constantly recorded video data will be saved. For example, if a drive recorder records video data by continuous recording while the vehicle is running and an accident or the like that is not subject to event recording occurs, the content of the accident or the like will be recorded as video data by continuous recording. Most likely recorded. That is, in reality, there are accidents that are not the target of event recording, but such accidents can be used for accident verification or the like by using the moving image data recorded by continuous recording.

However, if the parking mode is set, even though there is no need for monitoring while parking at the accident site or police, or while moving a tow truck or repairing at a repair shop, Continuous recording in parking mode starts. Then, when the capacity of the memory card reaches the upper limit, the moving image data in the parking mode overwrites the moving image data while driving. In this case, if the accident is the target of event recording, the video data remains in the event recording file, but if the accident is not the target of event recording, the video data of constant recording is overwritten. Therefore, you will not be able to see the video data of the accident.

The present invention has been proposed to solve the above-mentioned problems of the prior art, and an object of the present invention is that the moving image data while the vehicle is stopped may overwrite the previous moving image data. The purpose is to provide a drive recorder that can be reduced.

In order to achieve the above object, the drive recorder of the present invention includes a camera installed in a vehicle, a storage medium accommodating unit for accommodating a storage medium, a clock for measuring time, and the clock while the vehicle is stopped. It has a recording unit that records the moving image data taken by the camera in the storage medium when the time information measured by the camera corresponds to the set recording time zone.

When the position detection unit that detects the position of the vehicle and the position of the vehicle detected by the position detection unit correspond to the set recording position, and the time information measured by the clock is the recording time. When the band corresponds to the band, the recording unit may record the moving image data on the storage medium.

The recording time zone corresponds to the suppression time zone by the suppression time determination unit for determining whether or not the recording time zone corresponds to the set suppression time zone for suppressing overwriting, and the suppression time determination unit. It may have an overwriting notification unit that notifies a warning when it is determined to be so. When the time information measured by the clock corresponds to the set suppression time zone for suppressing overwriting, the recording unit may suppress the recording of the moving image data on the storage medium.

When the time length from the stop determination unit for determining the stop of the vehicle and the time when the stop determination unit determines the stop of the vehicle to the time when recording is started in the recording time zone is within the threshold value. It also has a recording notification unit that notifies a warning that recording is performed by the recording unit.

According to the present invention, it is possible to reduce the possibility that the previous moving image data is overwritten by the moving image data while the vehicle is stopped.

It is a block diagram which shows the whole structure of the drive recorder of an embodiment. It is a block diagram which shows the control part of embodiment. It is a figure which shows the setting screen example of the recording time and the suppression time of an embodiment. It is a flowchart which shows the operation procedure in the parking mode of an embodiment. It is a figure which shows the screen example which notifies the alarm of another aspect.

An embodiment of the drive recorder according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a drive recorder 1. The drive recorder 1 includes a camera 2, a microphone 3, a clock 4, a GNSS receiver 5, a storage medium accommodating unit 6, a power supply connection unit 7, an acceleration sensor 8, a gyro sensor 9, a display 10, a speaker 11, a lamp 12, and a control unit 13. Has.

The camera 2 captures a scene outside the vehicle and outputs moving image data. The camera 2 has a lens and an image pickup element such as CMOS or CCD, is fixed to the inner surface of the windshield of the vehicle, and the image pickup field of view is directed to the outside of the vehicle through the windshield. The microphone 3 collects sounds inside and outside the vehicle and outputs an audio signal.

The clock 4 generates time information. The time information indicates the current year, month, day, hour, minute, and second. The clock 4 is, for example, a system clock, and acquires and manages time information of a hardware clock or time information included in a positioning signal emitted by a satellite such as GPS when the drive recorder 1 is started.

The GNSS (Global Navigation Satellite System) receiving unit 5 receives the above positioning signal and detects the position information of the drive recorder 1 including the latitude, longitude and altitude and the vehicle on which the drive recorder 1 is installed. That is, the GNSS receiving unit 5 functions as a position detecting unit that detects the position of the vehicle. When the clock 4 measures the time information based on the time information included in the positioning signal, the positioning signal from the GNSS receiving unit 5 is used.

The storage medium accommodating unit 6 is a slot that accommodates the storage medium M and electrically connects the storage medium M and the drive recorder 1 so that data can be read and written. The storage medium M has a size that allows it to be detachably inserted into and removed from the storage medium accommodating portion 6. The storage medium M is a non-volatile memory, and is also called, for example, a memory card or an SD card. The moving image data is recorded on the storage medium M through the storage medium storage unit 6.

The power connection unit 7 is a socket to which the terminal of the power cord C is connected. The power cord C is connected to the constant power supply, accessory power supply, and ground terminal of the fuse box of the vehicle. As a result, the drive recorder 1 is supplied with electric power from the vehicle battery even when the vehicle engine is stopped and the accessory switch is turned off. Further, the drive recorder 1 can detect ON / OFF of the accessory switch. Since the accessory switch OFF is linked to the engine stop, the drive recorder 1 can indirectly detect the engine stop.

The acceleration sensor 8 is a sensor that detects the acceleration of the drive recorder 1. The gyro sensor 9 is a sensor that detects the angular velocity of the drive recorder 1. The acceleration sensor 8 and the gyro sensor 9 function as an impact detection unit that detects the posture of the vehicle and the impact received by the vehicle.

The display 10 is a device for displaying an image. The display 10 notifies the user of the information by displaying various information such as a moving image, a setting screen, and an alarm taken by the camera 2 in a predetermined layout. The display 10 is configured with a touch panel and also functions as an information input unit. By operating the touch panel, it is possible to select the menu displayed on the display 10 and input the settings.

The speaker 11 is an output device that notifies the user of specific information by converting an audio signal into voice and outputting it. The lamp 12 is an output device that notifies the user of specific information by continuously emitting light or blinking. An LED is used as the lamp 12. At least one of the display 10, the speaker 11, and the lamp 12 functions as an overwriting notification unit that notifies a warning described later.

The control unit 13 controls the operation of each unit of the drive recorder 1. The control unit 13 is a so-called computer that is mainly composed of a processor that is a central processing unit and is provided with various memories, input / output interfaces, and the like. The processor performs arithmetic processing for inputting, storing, outputting, etc. of information and controlling peripheral devices according to the main program.

The control unit 13 functions as various processing units by the processor reading and executing various programs, data, and settings stored in the memory. The present invention can also be grasped as a program as described above and a computer-readable storage medium in which such a program is recorded. In the following description, a block diagram in which the functions of each processing unit are illustrated by blocks is used. The program, data, and settings include the case where they are recorded on the storage medium M.

As shown in the block diagram of FIG. 2, the control unit 13 includes a recording unit 131, a stop determination unit 132, a time determination unit 133, a suppression time determination unit 134, and a position determination unit 135. The recording unit 131 records the moving image data captured by the camera 2 on the storage medium M. Hereinafter, recording video data is referred to as recording.

The recording mode of the recording unit 131 includes continuous recording and event recording. The continuous recording is a mode in which continuous recording is performed while power is being supplied to the drive recorder 1. In event recording, when vibration from the outside exceeds the threshold value, continuous recording is interrupted, and relatively short-time video data before and after the time when the threshold value is exceeded is saved as a separate file from continuous recording. This is the mode to save with. As described above, in the continuous recording, the recording may be temporarily interrupted by the event recording and then restarted.

In continuous recording, the recording unit 131 records the moving image data captured by the camera 2 on the storage medium M. At this time, moving image data at regular time intervals is created as a file having a predetermined size, and the file is recorded in a predetermined storage area of the storage medium M. When the free space of the predetermined storage area of the storage medium M is insufficient, the newest file is sequentially overwritten and recorded in the storage area in which the oldest file is recorded.

In event recording, the recording unit 131 creates a file separate from the constantly recorded moving image data. For example, moving image data for a period from several tens of seconds before to several tens of seconds after the occurrence of an accident is created as one file, and the file is recorded in a storage area different from the storage area for continuous recording of the storage medium M. When the free space of the predetermined storage area is insufficient, the moving image data of the event recording is also recorded by sequentially overwriting the newest file in the storage area in which the oldest file is recorded. However, since the storage area for event recording and the storage area for constant recording are distinguished, they are not overwritten by the continuous recording moving image data.

The recording unit 131 may record at least moving image data. However, in the present embodiment, the recording unit 131 continuously records the audio signal input from the microphone 3 at the time of shooting by the camera 2 as audio data together with the moving image data on the storage medium M.

Further, the drive recorder 1 of the present embodiment has a parking mode function of constantly recording even after the vehicle has stopped, in addition to constantly recording from the start to the stop of the vehicle. The activation of the vehicle as used herein means that the drive source of the vehicle is activated. Further, the stop of the vehicle means that the drive source is stopped. This includes the case where the drive source is an engine and the case where the drive source is a motor. For example, the drive recorder 1 can receive power supply via the power supply connection unit 7 even after the engine is stopped, and can perform continuous recording. Event recording can also be performed. The storage area for continuous recording in parking mode is also the same as the storage area for continuous recording when the engine is started. It is overwritten and recorded in sequence.

The stop determination unit 132 determines that the vehicle has stopped. For example, the stop determination unit 132 can determine the stop of the vehicle, that is, the stop of the engine by detecting the OFF of the accessory power supply of the vehicle via the power cord C.

The time determination unit 133 determines whether or not the time information measured by the clock 4 corresponds to the set recording time zone. The recording time zone refers to information for defining a period during which video data is continuously recorded, and includes information at the start time and end time of recording. The start time for starting recording can be set as the information at the start time, and the end time for ending recording can be set as the information at the end time. For example, the start time can be 22:00 and the end time can be 6:00.

Further, the information at the start time and the end time may be the elapsed time from the reference time. For example, the start time can be 6 hours from the stop of the vehicle and the end time can be 2 hours from the start time. Further, the recording time zone may include any information of year, month, day, and day of the week. For example, it can be three days from November 12th to 15th, 2019, November to December, or every Monday to Friday. Also in this case, the start time point and the end time point are set as described above.

Such a recording time zone is set in advance in the memory of the control unit 13, the storage medium M, and the like. It can be set by the user by inputting a desired recording time zone using an input device such as a touch panel of the display 10. For example, as shown in FIG. 3A, it can be set by using the input form of the start time and the end time displayed on the display 10.

When the time information corresponds to the recording time zone, it means that the time corresponds to the time between the start time and the end time. Continuous recording of moving image data means recording during the recording time zone, but may include interruption due to event recording. Further, the recording time zone may include a plurality of pairs at the start time and the end time. For example, it may be set from 21:00 to 22:00 and from 4:00 to 5:00.

The deterrence time determination unit 134 determines whether or not the set overwriting corresponds to the deterrence time zone to be deterred. When the suppression time determination unit 134 determines that the recording time zone corresponds to the suppression time, the overwriting notification unit notifies a warning. For example, as shown in FIG. 3B, the display 10 displays a warning "The video data in the set time zone will be overwritten. Is that okay?" The sound corresponding to this may be output by the speaker 11, and the lamp 12 may be turned on or blinked. As a result, it is possible to prompt the re-entry of the recording time zone. In the present embodiment, even if the time is set as the suppression time zone, when the time set in the recording time zone is reached, the recording is preferentially executed, so that it may be overwritten. It is supposed to be.

The suppression time zone is a time zone for suppressing overwriting by the parking mode, and is information including a start time and an end time of suppressing overwriting as in the recording time zone. The deterrence time zone may be set by the time at both the start time and the end time, for example, from 21:00 to 21:30, 30 minutes before the vehicle stops, and 30 minutes after the vehicle stops. , The time length from the reference time may be set. Such a suppression time zone is set in advance in the memory of the control unit 13, the storage medium M, and the like. It can be set by the user by inputting a desired suppression time zone using an input device such as a touch panel of the display 10. For example, as shown in FIG. 3C, the start time and end time input forms displayed on the display 10 can be used for setting.

The position determination unit 135 determines whether or not the position of the vehicle detected by the GNSS receiving unit 5 corresponds to a preset recording position. The recording position is position information specified by coordinates including at least latitude and longitude. The vehicle position information detected by the GNSS receiver 5 also includes coordinates including at least latitude and longitude. Whether or not it corresponds to the recording position is determined by comparing the coordinates of the vehicle position information with the coordinates of the recording position. When the distance between the coordinates of the recording position and the coordinates of the position information of the vehicle is within the threshold value, it can be determined that the distance corresponds to the recording position.

Such a recording position is set in advance in the memory of the control unit 13, the storage medium M, or the like. The vehicle position information acquired by the GNSS receiving unit 5 or the position information acquired from the navigation device, radar detector, or the like connected to the drive recorder 1 can be set as the recording position. For example, the recording position can be set as the position where the parking lot at home, the parking lot at work, etc. should be recorded.

[motion]
The processing procedure of the present embodiment as described above will be described with reference to the flowchart of FIG. 4 in addition to the above drawings. The following description is the operation of the parking mode in which the drive recorder 1 installed in the vehicle whose drive source is the engine records the moving image data while the engine is stopped. As a premise of shifting to the parking mode, it is assumed that continuous recording and event recording are being executed while the engine is starting. Further, as described above, it is assumed that the recording time zone and the recording position are set in advance.

When the stop determination unit 132 determines that the engine has stopped (step S101), the recording unit 131 stops the constant recording that was being performed while the engine was starting (step S102). The position determination unit 135 determines whether or not the position of the vehicle detected by the GNSS receiving unit 5 corresponds to the set recording position (step S103). If it does not correspond to the recording position (NO in step S103), recording in the parking mode is not performed.

When the position of the vehicle corresponds to the recording position (YES in step S103), the time determination unit 133 determines whether or not the time information measured by the clock 4 corresponds to the set recording time zone (YES in step S103). Step S104). That is, it is determined whether or not the current time is the time between the start time and the end time of recording in the parking mode.

If the current time does not correspond to the recording time zone (NO in step S104), the time determination unit 133 waits for the arrival of the start time of the recording time zone until the engine starts (NO in step S105). When the engine is started (YES in step S105), the parking mode is terminated and continuous recording while the engine is running is started.

When the current time corresponds to the recording time zone (YES in step S104), the recording unit 131 starts continuous recording in the parking mode (step S106). Event recording may also be performed during this constant recording. For example, when vibration is applied due to vandalism on the vehicle, event recording is performed. If the engine is started during such recording (YES in step S107), continuous recording is stopped (step S109), the parking mode is terminated, and continuous recording during startup is started.

Recording is continued without starting the engine (NO in step S107), and even when the current time reaches the end time of the recording time zone (YES in step S108), recording is stopped (step S108). S109), the processing of the parking mode is terminated. The process of step S103 may be omitted. For example, the position determination unit 135 and the setting of the recording position are not essential in this embodiment.

Specific examples of setting the recording time zone and recording position of the present embodiment as described above are as follows.
(1) Start time and end time For example, 22:00 is set as the start time and 6 o'clock is set as the end time. As a result, the recording time zone is from 22:00 to 6:00 every day. Then, if you park your car at 21:00, recording will not start from 21:00 to 22:00. After that, when the start time is 22:00, continuous recording is started, and recording is performed until 6 o'clock, which is the end time. After that, continuous recording is not performed until the engine of the vehicle is started.

In addition, when the vehicle is parked at home at 23:00, it is parked at a time corresponding to the recording time zone, that is, at a time after the start time, so recording is always performed from 23:00 to 6:00. After that, continuous recording is not performed until the engine of the vehicle is started. In this way, by constantly recording the parking mode only in a specific time zone, it is possible to monitor the vehicle by vandalism or a time zone where there are many suspicious persons according to the time of returning home or the time of coming to work.

(2) Month / day As the recording time zone, the month / day to record, the start time, and the end time can be set. For example, for four days from November 12th to 15th, 21:00 is set as the start time and 23:00 is set as the end time. In this case, even if the car is parked from 20:00 to 6:00, recording is performed only from 21:00 to 23:00 from November 12 to 15, which is set. In this way, it is possible to set a necessary time zone and use it for monitoring on a day when a person goes to a specific place such as a business trip destination or a travel destination.

(3) Location For example, when it is desired to set the work place as a monitoring place, the recording position is set in advance at the work place, and the time zone is set from 13:00 to 18:00. As a result, not only the time zone but also the recording position in the parking mode can be limited.

(Action effect)
In the present embodiment as described above, the camera 2 installed in the vehicle, the storage medium accommodating unit 6 accommodating the storage medium M, the clock 4 for measuring the time, and the clock 4 measuring while the vehicle is stopped. It has a recording unit 131 that records the moving image data taken by the camera 2 on the storage medium M when the time information corresponds to the set recording time zone.

Therefore, when the vehicle is stopped, the moving image data is recorded in the storage medium M only during the set recording time zone, so that the past moving image is compared with the case of continuously recording from the stopping to the starting of the vehicle. The possibility that the data will be overwritten can be reduced. In addition, by setting the recording time zone not during the time when the vehicle travels on a daily basis but during the time when the vehicle is parked, it is unlikely that an accident or the like will be encountered, and it will be during the time when monitoring is required. Only can record in parking mode. As a result, even if you encounter an accident that is not subject to event recording while driving, you can switch to parking mode while parking at the accident site or police, or while moving a tow truck or repairing at a repair shop. It is possible to reduce the possibility that recording will start and the video data of the accident will be overwritten. In other words, by distinguishing between the time zone that requires daily monitoring and the time zone where irregular accidents are likely to occur, the former is always recorded and the latter is not constantly recorded, so that the video data of the accident Can be increased in the possibility of being preserved.

Further, in the adapter that supplies power for continuous recording, when the time for supplying power is limited or when the power supply is stopped when a voltage drop is detected, recording is started after the engine is stopped, and a predetermined value is obtained. Since the power is only turned off in time, the user may not be able to record at the time required for monitoring. In the present embodiment, since the user can start recording in the parking mode at a desired time zone, it is possible to obtain moving image data necessary for monitoring.

The position detection unit that detects the position of the vehicle and the position of the vehicle detected by the position detection unit correspond to the set recording position, and the time information measured by the clock 4 corresponds to the recording time zone. In this case, the recording unit 131 records the moving image data on the storage medium M.

Therefore, it is possible to record in the parking mode not only in the time zone but also in a limited place. For example, by setting a parking lot at home or setting a location where theft occurs frequently, it is possible to constantly record only in a place where monitoring is required. It should be noted that the possibility of overwriting the video data can be reduced by only recording in the parking mode only at a specific position, but even in this case, recording is started immediately after the engine is stopped. If continuous recording is performed, recording in a desired time zone may not be possible. In the present embodiment, since recording can be performed only in the set recording time zone, the possibility of overwriting the moving image data can be further reduced.

The suppression time determination unit 134 that determines whether the recording time zone corresponds to the set suppression time zone for suppressing overwriting and the suppression time determination unit 134 determine that the recording time zone corresponds to the suppression time zone. It has an overwriting notification unit that notifies a warning when the notification is made. Therefore, it is possible to reduce the possibility that the moving image data in the time zone that the user does not want to be overwritten is lost.

[Other Embodiments]
The present invention is not limited to the above embodiments, but also includes other embodiments shown below. The present invention also includes a combination of all or any of the above embodiments and the following other embodiments. Furthermore, various omissions, replacements, and changes can be made to these embodiments without departing from the scope of the invention, and modifications thereof are also included in the present invention.

When the time length from the time when the stop determination unit 132 determines that the vehicle is stopped to the time when recording is started in the recording time zone is within the threshold value, the recording unit 131 warns that recording will be performed. It may have a recording notification unit for notification. In this case, the control unit 13 has a time length determination unit that determines whether or not the time length is within the threshold value. The recording notification unit is at least one of the display 10, the speaker 11, and the lamp 12. For example, as shown in FIG. 5, a character indicating that the moving image data may be overwritten by the parking mode is displayed on the display 10, the sound is output from the speaker 11, and the lamp 12 is turned on or blinked. .. In this case, the display 10 may be displayed to indicate whether or not to stop the parking mode, and the recording in the parking mode may be stopped or continued according to the input.

When a time zone in which the vehicle is normally parked and not running is set as the recording time zone, recording in the parking mode is not performed in the time zone in which an accident is likely to occur due to running. However, the user does not always live on such a driving schedule, and may have an accident while driving the vehicle during the recording time zone or the time immediately before the recording time zone. For example, if the start time of the recording time zone is short, such as within 30 minutes from the time the engine is stopped, the recording of the parking mode will start while the response is being taken immediately after the accident, and the video of the accident will be recorded. The data may be overwritten. Therefore, if recording starts within a time within the threshold value when the engine is stopped, the possibility that the video data of the accident will be overwritten can be reduced by giving a warning as a warning. .. In addition, there is no need to bother to warn the parking mode after the vehicle is stopped.

Further, when the time information measured by the clock 4 corresponds to the set suppression time zone in which overwriting should be suppressed, the recording unit 131 may suppress the recording of the moving image data on the storage medium M. .. For example, when the suppression time determination unit 134 determines that the time information measured by the clock 4 corresponds to the suppression time zone, the recording unit 131 is set not to record the moving image data. As an example, it is assumed that the deterrent time is set to 30 minutes after the vehicle stops. Then, 30 minutes after the stop determination unit 132 determines that the vehicle has stopped, the recording unit 131 does not record the moving image data. As a result, the activation of the parking mode is suppressed when the vehicle returns within 30 minutes after the vehicle is stopped. With this function, it is possible to further reduce the capacity that is overwritten in the parking mode each time even though the vehicle is stopped only for a short time. In this aspect, it is premised that overwriting is suppressed without recording even if the time is set in the recording time zone. However, if the time of disclosure of the recording time zone arrives during the suppression time, recording may be started. Instead of setting the suppression time zone, set the start time of the recording time zone as a time point that is relatively short after the vehicle stops, for example, 30 minutes after the vehicle stops. The same effect as described above can be obtained by the above method.

The drive recorder 1 of the present embodiment may be provided in a common housing, but it is not always necessary, and a part of the drive recorder 1 may be provided separately. For example, the housing of the camera 2 is separated from the housing of the main body of the drive recorder 1, the main body is installed at a position that is easy for the user to operate, and the camera 2 is installed at a position suitable for monitoring while parking.
