Description

Technical Field

[0001] The present invention relates to, for example, a power supply device, a video recorder, a program, and the like.

Background Art

[0002] For example, an in-vehicle recording device, so-called a drive recorder, which is mounted on a vehicle, captures images around the vehicle, and records surrounding images, vehicle speed, etc. when an impact is applied to the vehicle due to an event (incident) such as sudden braking, sudden steering, or collision, is generally widespread (see, for example, Patent Document 1).

[0003] The drive recorder (vehicle recording device) described in Patent Document 1 constantly records images and detects events while the vehicle is operating rather than in a parked state. Also, when the vehicle is parked and power is supplied from the vehicle battery, the drive recorder constantly records images and detects events, and when operating with a battery dedicated to the drive recorder, it detects events and captures images when an event is detected (see paragraph 0043 of Patent Document 1). In this drive recorder, it determines that the vehicle is in a parked state when the shift position becomes "parking", the side brake is operated, for example, the speed has become zero for a time of 5 seconds or more, the engine has stopped, or an arbitrary trigger such as a user operation has occurred.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In recent years, more convenient drive recorders and other systems have been desired. For example, in a system such as that disclosed in Patent Document 1 which can continue recording while the vehicle is parked, there are also drive recorders that cannot directly obtain information regarding the state of the shift position, side brake, vehicle speed, engine, etc. For such drive recorders that cannot directly obtain information on the vehicle side, a system capable of determining the state of the vehicle is desired.

[0006] In view of the above-described problems, one object of the present invention is to provide a highly convenient power supply device, recorder, program, and the like.

[0007] The object of the present invention is not limited to this, and the applicant also has the intention of obtaining rights by means of divisional applications, amendments, etc. for configurations aimed at obtaining effects achieved by parts of the configurations disclosed in this specification and the drawings, etc. For example, in this specification, problems obtained by reading parts described as "can ~" or "is possible to ~" as "is a problem of ~" are disclosed in this specification. The problems are described as independent ones, and the applicant also has the intention of obtaining rights by means of divisional applications, amendments, etc. alone for the configurations for solving each problem. Even if the problems are implicitly understood from the description of the specification, the applicant has the intention of making part of the configurations described in this specification the scope of the claims by amendment or divisional application. Also, configurations for solving problems combining these independent problems are disclosed, and the applicant has the intention of obtaining rights.

Means for Solving the Problems

[0008] In order to solve the above-described problems, a power supply device according to the present invention is a power supply device that can be charged from an accessory power supply of a vehicle and can supply power to a recorder having a recording function, is connected to the recorder via a communication line, and has a function of transmitting the OFF state of the accessory power supply of the vehicle via the communication line.

[0009] By using a communication line that enables information transmission between a video recorder and a power supply device connected to an accessory power supply, it becomes possible to transmit the OFF state of the accessory power supply. As a result, even a video recorder that cannot directly detect a signal indicating the OFF state of the accessory power supply can detect the OFF state of the accessory power supply. For example, even when the parking recording start condition is the OFF state of the accessory power supply, it becomes possible to easily handle it. By doing so, convenience can be enhanced.

[0010] Also, in the present invention, (2) when a signal regarding the video recorder is not transmitted from the video recorder to the power supply device via the communication line, it may have a function of transmitting the OFF state of the accessory power supply based on the state of the communication line. In this way, the video recorder can identify by itself from the communication state with the video recorder that it is a model that cannot communicate in terms of signal transmission and reception related to the video recorder (for example, the video recording function), and can transmit a signal indicating the OFF state of the accessory power supply.

[0011] Also, in the present invention, (3) when a predetermined communication signal is transmitted from the video recorder to the power supply device via the communication line, it is preferable to send a signal indicating the OFF state of the accessory power supply. In this way, the drive recorder can identify by itself from the communication state with the drive recorder that it is a communication-enabled model, and can transmit a signal indicating the OFF state of the accessory power supply by using the original communication function.

[0012] Also, in the present invention, (4) the communication line may be a communication line capable of UART communication. By doing so, it is possible to use an existing cable without the need to newly add a special communication line. A communication line capable of UART communication is provided, for example, in a cable having a 10-pin mini USB terminal.

[0013] Also, in the present invention, (5) the communication line includes a first signal line used for transmitting a signal from the video recorder to the power supply device and a second signal line used for transmitting a signal from the power supply device to the video recorder. When the level of the first signal line is in the first state, a signal indicating the OFF state of the accessory power supply is sent through the second signal line. When the level of the first signal line is in the second state, it has a function of switching the level of the second signal line in response to the OFF state of the accessory power supply. By doing so, as a power supply device, the same effect as that in (1) above can be achieved, and the video recorder can recognize the state of the accessory power supply regardless of whether the video recorder can receive and recognize a signal indicating the OFF state of the accessory power supply.

[0014] Also, (6) when the level of the first signal line is in the first state, it preferably has a function of sending a signal indicating predetermined communication information different from the signal indicating the state of the accessory power supply through the second signal line. By doing so, the signal line for making the video recorder recognize the state of the accessory power supply and the signal line for sending a signal indicating predetermined communication information can be shared. Instead of using a dedicated communication line for sending a signal indicating the state of the accessory power supply, using a communication line for transmitting a signal related to the recording function (for example, a signal such as setting information of the recording function) can suppress the complication of the wiring structure and it is also easy to transmit the OFF state of the accessory power supply using an existing standard cable or the like.

[0015] (7) The video recorder according to the present invention has a recording function and operates by receiving power supply from any of the above power supply devices. It is provided with a connection terminal to which a communication line for connecting to the power supply device is connected. The communication line has a first signal line for transmitting a signal to the power supply device and a second signal line for transmitting a signal from the power supply device. The connection terminal has a first terminal electrically connected to the first signal line and a second terminal electrically connected to the second signal line. When the communication line is connected to the connection terminal, the level of the first terminal is in a second state, and it has a function of recognizing the OFF state of the accessory power supply of the vehicle according to the switching between the second state and the first state of the level of the second terminal.

[0016] In this way, even without receiving and recognizing a signal indicating the OFF state of the accessory power supply of the vehicle via the communication line, the OFF state of the accessory power supply of the vehicle can be recognized.

[0017] Also, in the present invention, (8) it may be configured not to have a function of outputting a signal related to the setting of the recording function via the first terminal.

[0018] In this way, even in a video recorder that does not have a communication function of outputting a signal related to the setting of the recording function toward the power supply device, the OFF state of the accessory power supply of the vehicle can be recognized.

[0019] Also, in the present invention, (9) the connection terminal may be a terminal used for UART communication.

[0020] In this way, a special - standard terminal is not required for the connection terminal, and an existing - standard terminal can be used. The terminal used for UART communication is, for example, a 10 - pin mini - USB terminal.

[0021] In addition, in the present invention, (10) the recording function may start recording using the power supplied from the power supply device in response to recognition of the OFF state of the accessory power supply of the vehicle according to the switching of the level of the second terminal.

[0022] By doing so, even without receiving a signal indicating the OFF state of the accessory power supply of the vehicle via the communication line and recognizing this signal, recording by the recording function can be started in response to the OFF state of the accessory power supply of the vehicle.

[0023] (11) It is preferable to use a program for causing a computer to realize the function of any one of the systems (1) to (6) above. In this way, the functions (1) to (6) can be executed by the computer.

[0024] (12) It is preferable to use a program for causing a computer to realize the function of any one of the systems (7) to (11) above. In this way, the functions (7) to (11) can be executed by the computer.

[0025] The inventions described in (1) to (12) above can be arbitrarily combined. For example, it may be configured to add at least a part of the configuration of at least one of the inventions after (2) to all or a part of the configuration of the invention described in (1). In particular, it is preferable to use an invention in which at least a part of the configuration of at least one of the inventions after (2) is added to the invention described in (1). Also, any configuration can be extracted from the inventions described in (1) to (12), and the extracted configurations can be combined. The applicant of the present application intends to obtain rights for inventions including these configurations. Also, even if there is a description such as "in the case of ~" or "when ~", it is not described as a configuration limited to that case or that time. These show examples of better configurations, and the applicant also intends to obtain rights for configurations other than these cases and times. Also, the order in the described parts with an order is not limited to this order. The disclosure also includes configurations in which some parts are deleted or the order is changed, and the applicant intends to obtain rights for them.

[0029] Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. Note that the embodiments shown below are one of the embodiments providing the present invention, and the content of the invention of this application is not limitedly interpreted based on the following description.

[0030] [Configuration of the System] With reference to FIGS. 1 and 2, an example of the configuration of the system will be described. The "system" may be one that attaches part or all of the system to a moving body. Further, when attaching part of the "system" to a moving body, it is preferable to enable, for example, an imaging unit such as a camera to be attached to the moving body, and for the control unit, it may be provided at a location separated from the moving body to which the imaging unit is attached. Further, the "system" may have the functions of a drive recorder and other imaging devices.

[0031] Further, the moving body to which part or all of the system is attached may be not only a vehicle such as an automobile or an electric vehicle, but also a system mounted on an object other than a vehicle. Examples of objects other than vehicles include, for example, systems mounted on vehicles in transportation means such as trains, linear motor cars, and monorails, ships, and moving bodies other than vehicles such as airplanes (e.g., vehicles), but it is preferable to be a system mounted on a vehicle in particular. The vehicle is not limited to a four-wheeled automobile, and may be, for example, a two-wheeled vehicle such as a motorcycle or a large transport vehicle with four or more wheels, and particularly preferably a four-wheeled automobile capable of observing from inside the vehicle compartment to outside the vehicle compartment. As the vehicle, for example, not only all vehicles such as transportation vehicles (e.g., trucks and forklifts), business vehicles (e.g., taxis and buses), and general vehicles, but also further expandable for more versatile uses. In this embodiment, a drive recorder, which is an example of a recorder mountable on a vehicle, will be described.

[0032] Further, when the "imaging unit" is a camera, the camera may be provided at a plurality of locations on the vehicle. For example, a camera different from the front camera of the vehicle is provided for the rear of the vehicle, and it is preferable to image other moving bodies and the like with two cameras, namely, the front camera of the vehicle (hereinafter referred to as the "front camera") and the rear camera of the vehicle (hereinafter referred to as the "rear camera"). Further, the front camera or the rear camera may be a camera capable of imaging with a 360-degree viewing angle so as to be able to image the state inside the vehicle as well.

[0033] The system according to this embodiment includes a drive recorder 1 (an example of a recording device) having a recording function for recording video images captured in the vehicle 100.

[0034] The drive recorder 1 has two imaging units, a front camera 10 provided in front of the vehicle and a rear camera 20 provided behind the vehicle. The front camera 10 and the rear camera 20 capture video images of multi-color components such as red (R), green (G), and blue (B), but the types and numbers of color components can be variously modified.

[0035] Fig. 1(a) is a perspective view showing the front camera 10 of the drive recorder 1. As shown in Fig. 1(a), a memory card insertion slot 11 is provided on one side surface of the housing of the front camera 10. On the back surface of the housing, a display 12 and an operation unit 13 (in the example shown in Fig. 1(a), a plurality of operation buttons 13a to 13d) are provided. For example, in this embodiment, the operation button 13a is a display button for switching video images, the operation button 13b is a mode button for displaying the playback mode, the operation button 13c is a REC / STOP button for starting / stopping recording, the operation button 13d is a menu button for displaying the setting menu, and the operation button 13e is a recording button for manually starting event recording described later.

[0036] In addition, a joint rail 14 is provided on the upper surface of the housing. Although not shown in Fig. 1(a), a lens of the front camera 10, which is an example of an imaging unit, is provided on the front surface of the housing. A connection terminal 15 is provided on the side surface opposite to the side surface of the memory card insertion slot 11, and a speaker and an HD output terminal are provided on the bottom surface although not shown in Fig. 1(a).

[0037] The front camera 10 having a lens captures, for example, an image in front of a vehicle. The memory card insertion slot 11 is an insertion slot for inserting a memory card. The speaker outputs sounds such as voices. The HD output terminal is a terminal for connecting to other information devices via a cable. The joint rail 14 is for attaching a joint member for mounting the front camera 10 to a vehicle. The display 12 displays various images. The operation unit 13 is for a user to input various commands to the drive recorder 1 by operating it.

[0038] Note that in this embodiment, the user may be, for example, a driver of a vehicle or the like on which the drive recorder 1 is mounted, or a person different from the driver, such as a passenger.

[0039] FIG. 1(b) is a view showing the front of the vehicle where the front camera 10 of this embodiment is installed. In the example shown in FIG. 1(b), the front camera 10 of the drive recorder 1 is arranged at a position on the passenger seat side adjacent to the rearview mirror 102 near the center in the left - right direction at the upper part of the front glass 101 of the vehicle 100. The front camera 10 is fixed by being attached to the front glass 101 with an attachment member such as double - sided tape. The connection terminal 15 of the front camera 10 is connected to the accessory power supply 110 via the power unit 16. The connection terminal 15 and the power unit 16 will be described later.

[0040] FIG. 1(c) is a view showing the rear of the vehicle where the rear camera 20 is installed. In the example shown in FIG. 1(c), the rear camera 20 is fixed by being attached to the rear glass 104 of the vehicle with an attachment member at the upper part near the center in the left - right direction. The rear camera 20 shown in FIG. 1(c) has a display function, but this is not essential. It is preferable to provide a display on the dashboard 105 for displaying the image captured by the rear camera 20 so that the image captured by the rear camera 20 can be viewed in front.

[0041] The drive recorder 1 may be configured to perform imaging with two cameras, separately including a front camera 10 and a rear camera 20, and to provide various functions only on the front camera 10 side, with the rear camera 20 connected to the front camera 10. Also, the drive recorder 1 may be provided with a function to perform various settings on the front camera 10 side, and the front camera 10 and the rear camera 20 may be made to operate according to the settings performed on the front camera 10 side. However, this is not essential, and a system capable of performing various functions and various settings may be mounted on the front and rear of the vehicle respectively.

[0042] As shown in Fig. 1(a), some members of the drive recorder 1 may be provided at positions different from the front windshield 101 according to the use of the members. For example, an operation button 13f, which is one of the operation units 13, may be provided on the dashboard 105 as shown in Fig. 1(b). The controller 30 may, for example, transmit video data captured by a camera to the outside and record the video data outside.

[0043] Fig. 2 is a block diagram showing the schematic system configuration of the drive recorder of the present embodiment. The drive recorder 1 includes, in addition to the above-described front camera 10 (an example of an imaging unit) and rear camera 20 (an example of an imaging unit), a display 12, an operation unit 13 including operation buttons 13a to 13f, a connection terminal 15, a power supply unit 16, a controller 30 (an example of a control unit), a speaker 40, a GPS receiver 41, an acceleration sensor 42, a wireless communication circuit 43, and a memory card reader 44. Note that the memory card reader 44 has a read / write function and should strictly be referred to as a "memory card reader / writer", but in this specification, it is simply referred to as a "memory card reader".

[0044] The display 12 and the speaker 40 function as a notification unit for notifying the user of various information. The display 12 outputs various information as an image display based on the control of the controller 30. The speaker 40 outputs alarms and various information as sounds based on the control of the controller 30. The operation unit 13 functions as an input means for the user to give various commands to the drive recorder 1 (more specifically, the controller 30).

[0045] In this embodiment, the front camera 10 functions as an imaging unit whose lens is directed forward of the vehicle 100 and captures an image within the angular field (field of view) in front of the vehicle. The image captured by the front camera 10 is taken into the controller 30 as video data. The front camera 10 can at least capture the front of the vehicle. The front camera 10 may, for example, be provided with a camera for capturing the front and a camera for capturing the interior of the own vehicle separately and capture each, or it is even better to adopt, for example, a camera with a 360-degree field of view so that both the front and the interior of the own vehicle can be captured.

[0046] In this embodiment, the rear camera 20 functions as an imaging unit whose lens is directed rearward of the vehicle 100 and captures an image within the angular field (field of view) behind the vehicle. The image captured by the rear camera 20 is taken into the controller 30 as video data. Note that the rear camera 20 can at least capture the rear of the vehicle, and it is even better if it can capture the side in addition to the rear. Also, in this embodiment, the imaging unit consists of two cameras, the front camera 10 and the rear camera 20, but the number of imaging units may be one or two or more.

[0047] The GPS receiver 41 detects the position information of the own vehicle at the current time based on the instruction of the controller 30. The position information detects the time obtained based on the signal from the GPS satellite, the speed, longitude, latitude, altitude, etc. of the own vehicle. The controller 30 performs a process of recording the history of this position information.

[0048] The acceleration sensor 42 uses a three-axis type sensor that detects the acceleration and inclination in the directions of each of the three axes (x-axis, y-axis, z-axis). The measured values by the acceleration sensor 42 are constantly taken into the controller 30. The controller 30 acquires the acceleration information of the three axes, for example, every 10 ms.

[0049] The wireless communication circuit 43 functions as a communication unit for performing wireless communication with external devices, such as a server (for example, a server of a public institution such as the police, a server of a website operation company on the Internet that can be viewed by anyone, etc.), a personal computer, a smartphone, a tablet terminal, etc. The controller 30 has a function of transmitting video data to an external device via the wireless communication circuit 43 by executing a wireless communication processing program. As the wireless communication circuit 43, for example, a communication circuit compliant with a short-range wireless communication standard such as the WiFi standard, Bluetooth (registered trademark), or a standard of a mobile communication system such as LTE (Long Term Evolution), 4G, 5G, etc. may be used. The standard of the mobile communication system can be applied, for example, to the communication between a vehicle moving within a wider area and an external device.

[0050] The memory card reader 44 functions as a medium accommodating unit that holds the memory card 45. The memory card 45 is specifically an SD card, a miniSD card, a microSD card, etc., and functions as a removable recording medium. The user can attach the memory card to the memory card reader 44 through the memory card insertion slot 11. The memory card reader 44 reads the data of the memory card 45 held in the memory card reader 44 or records data on the memory card 45 based on the control from the controller 30. The memory card reader 44 is preferably separated into an area for recording the data captured by the front camera 10 and an area for recording the data captured by the rear camera 20 on the other side. It may have separate recording areas on one memory card, but it is preferable to be able to attach two or more memory cards and record the data captured by the front camera 10 on the first memory card and the data captured by the rear camera 20 on the second memory card.

[0051] The controller 30 includes an arithmetic processing unit such as a well-known CPU 31, memories such as a ROM 32 and a RAM 33, a timer 34, and other peripheral circuits. Various programs are recorded in the ROM 32 of the controller 30. The controller 30 realizes various functions by executing these programs. The various programs include an operating system (OS), a GPS information processing program, a wireless communication processing program, a recording processing program, and the like. The GPS information processing program, the wireless communication processing program, and the recording processing program do not necessarily have to be independent programs, and programs combining a plurality of these functions may be used.

[0052] By executing the GPS information processing program, the controller 30 can record the GPS information received by the GPS receiver 41 in the memory card 45 held by the memory card reader 44.

[0053] By executing the recording processing program, the controller 30 can record the images captured by the front camera 10 and the rear camera 20 in the recording area of the memory card 45 in association with the time. The controller 30 has a function of accessing the memory card 45 held by the memory card reader 44, and functions as a control unit having a recording function of recording the images captured by the front camera 10 and the rear camera 20 in the memory card held by the memory card reader 44. Specifically, the recording function of the controller 30 records the video data captured by the front camera 10 and the rear camera 20 by temporarily writing it into the RAM 33 and then writing it from the RAM 33 to the memory card 45 via the memory card reader 44.

[0054] In the recording function of the controller 30, various settings are possible, and the settings of the recording function will be described in detail below.

[0055] The controller 30 of this embodiment has an event recording mode, a continuous recording mode, and a parking recording mode as recording modes. The parking recording mode is a mode associated with a parking recording function that records while the vehicle 100 is parked. The parking recording function is a function related to recording while the vehicle 100 is parked. The parking recording function is sometimes also called a parking monitoring function in the sense of monitoring the inside or the periphery of the parked vehicle 100. Specifically, the parking recording function is executed by selecting at least one of the time-lapse mode and the moving object detection mode. The event recording mode can be executed in parallel as a multi-task even when the continuous recording mode or the parking recording mode is selected.

[0056] The event recording mode is a recording mode for recording video data captured by the front camera 10 and the rear camera 20 in response to the occurrence of a specific event (for example, an event). The specific event is, for example, an event such as when the user suddenly steers or brakes during vehicle travel, or when the vehicle collides with another object. The controller 30 determines such a specific event from, for example, the measured value by the acceleration sensor 42. Specifically, the controller 30 determines that a specific event has occurred when the measured value by the acceleration sensor 42 is equal to or greater than a predetermined threshold value or shows a predetermined temporal change. The determination condition of the specific event is not limited to this, and for example, vehicle states such as vehicle speed and steering state may be included as conditions. In addition, the controller 30 also determines that a specific event has occurred when a specific operation button of the operation unit 13 (for example, the operation button 13e in FIG. 1(a)) is pressed. Incidentally, the imaging and recording in the event recording mode by pressing the operation button 13e are also referred to as one-touch recording hereinafter. Note that the operation that triggers the start of recording does not necessarily have to be one-touch, and any predetermined operation may be used. The recording in this case is a recording called manual recording or manual recording, and can be substituted for one-touch recording.

[0057] When the controller 30 is in the event recording mode, when the above-described specific event occurs, it records video data captured at a certain time before and after the event. For example, the controller 30 records a total of 40 seconds of video data, 20 seconds before the event and 20 seconds after the event, as one recording file on the memory card 45.

[0058] The continuous recording mode is a recording mode in which the front camera 10 and the rear camera 20 continuously capture and record video data. Specifically, when in the continuous recording mode, the controller 30 records at least the video data captured from the start to the stop of the engine of the vehicle 100. The start of the engine corresponds to, for example, the turning on of the accessory power supply of the vehicle 100, and the stop of the engine corresponds to the turning off of the accessory power supply. The determination of the turning on and off of this accessory power supply will be described later.

[0059] The time-lapse mode, which is one of the parking recording modes, is a recording mode in which the front camera 10 and the rear camera 20 perform intermittent imaging and recording. In the present embodiment, the intermittent imaging is to perform imaging at a frame rate thinned out from the reference frame rate. In the present embodiment, when the time-lapse mode is selected, the controller 30 sets the frame rate of imaging by the front camera 10 and the rear camera 20 to a frame rate lower than the reference frame rate, and performs imaging and recording. The reference frame rate may be, for example, the frame rate adopted in at least any one of the continuous recording mode, the event recording mode, the one-touch recording mode, and the moving object detection mode. For example, while the frame rate of other recording modes is, for example, 20 to 30 frames per second (hereinafter, may also be referred to as "frames per second"), the frame rate of the time-lapse mode is, for example, 1 frame per second.

[0060] The controller 30 of the present embodiment records the video captured in the time-lapse mode as a moving image temporally compressed. For example, video data captured at 1 frame / second is recorded as video data compressed to 30 frames / second equivalent to the frame rate of other recording modes. Note that the video data captured in the time-lapse mode may be recorded as a moving image of 1 frame per second.

[0061] Also, the moving object detection mode, which is one of the parking recording modes, is a recording mode that captures and records in response to the detection of a moving object. Specifically, when the moving object detection mode is selected, the controller 30 detects a moving object from the change in the video captured by the front camera 10 and the rear camera 20, and records the video data when there is movement (that is, when a moving object is detected). The frame rate in the moving object detection mode is higher than the frame rate in the time-lapse mode, for example, 20 to 30 frames / second. The controller 30 performs moving object detection based on the video data temporarily written in the RAM 33, and when a moving object is detected, records the video data on the memory card 45 based on the video data on the RAM 33 to perform recording.

[0062] The recording function of the controller 30 creates a new file and performs recording each time it records a video for a predetermined time. For example, in the continuous recording mode, it is 1 minute, in the time-lapse mode, it is 30 minutes, and in the event recording mode and one-touch recording, it is in units of 40 seconds or 30 seconds.

[0063] The controller 30 automatically starts recording (capturing and recording) for parking in the parking recording mode (specifically, the time-lapse mode or the moving object detection mode) in response to detecting, for example, that the accessory power supply of the vehicle 100 is OFF. In the present embodiment, detecting that the accessory power supply is OFF is performed using the communication line between the drive recorder 1 and the power supply unit 16, which will be described later. Note that in addition to detecting that the accessory power supply is OFF, the controller 30 may start the parking recording mode when a parking recording start condition such as the engine being OFF or a switching operation by the user to the parking recording mode at the operation unit 13 is satisfied.

[0064] The memory card 45, which is the recording destination of video data in the drive recorder 1, has at least two recording areas, namely a first recording area and a second recording area. The recording function realized by the recording processing program executed by the controller 30 records, in the first recording area (the event recording folder in this embodiment), video data captured in response to the occurrence of a specific event, i.e., in the event recording mode. Also, in the second recording area (the normal recording folder in this embodiment), video data captured in the above-mentioned always-on recording mode, time-lapse mode, and moving object detection mode is recorded.

[0065] The controller 30 has a playback function for playing back the video data recorded by the recording function. The playback function has a function of selectively playing back the video data captured by the front camera 10 and the video data captured by the rear camera 20. Regarding which video to play back, for example, it can be switched by the user operating a predetermined operation button on the operation unit 13.

[0066] The display 12 also functions as a notification unit that informs the user of the role played by the memory card 45 accessed by the controller 30.

[0067] Also, a viewer program having a function of simultaneously playing back the video data captured by the front camera 10 and the video data captured by the rear camera 20 may be provided.

[0068] Further, the display 12 may be provided on the dashboard 105 of the vehicle 100 as described above, or only a display capable of playing back only the video captured by the rear camera 20 among the videos captured by the front camera 10 and the rear camera 20 may be provided on the dashboard 105. Further, the playback function may be enabled not only for the display 12 of the drive recorder 1 but also for the displays of other information terminals such as a PC, a smartphone, a mobile phone, and a tablet terminal. For example, a viewer program having the playback function can be installed on other information terminals to realize the playback function for the displays of the information terminals. The viewer program may be provided to the information terminal from the drive recorder 1 via the wireless communication circuit 43, provided by recording it on the memory card 45, or provided via a communication network such as the Internet.

[0069] The drive recorder 1 configured as described above is connected to the accessory power supply 110 of the vehicle 100 from the connection terminal 15 via the power supply unit 16.

[0070] The connection terminal 15 of the drive recorder 1 is, for example, a 10-pin mini USB terminal (female terminal), and has a wiring structure having at least a power line, a ground (GND) line, and a UART communication line. The UART communication line is a communication line that performs asynchronous serial communication using two signal lines, UART_TX for data transmission and UART_RX for data reception. The drive recorder 1 is connected to the accessory power supply 110 of the vehicle 100 from the connection terminal 15 via the power supply unit 16.

[0071] Here, FIG. 3 shows an explanatory diagram of the connection configuration of the power supply unit, and FIG. 4 shows a schematic diagram of each line of the power supply unit 16. Based on these figures below, the connection relationship between the drive recorder 1 and the accessory power supply 110 of the vehicle 100 will be described.

[0072] As shown in FIGS. 3 and 4, the power supply unit 16 includes a first cable 50 (an example of a communication line), a converter 51, a second cable 52 (an example of a communication line), a battery unit 53 (an example of a power supply device), and a third cable 54.

[0073] The first cable 50 is a cable that connects the connection terminal 15 and the converter 51, and a 10-pin mini USB terminal (male terminal) that can be inserted into the connection terminal 15 is provided at the tip on the connection terminal 15 side.

[0074] The first cable 50 and the second cable 52 are respectively connected to the converter 51 so as to be integrated. It is a DC / DC converter that converts the DC (direct current) 12V power input from the second cable 52 into DC 5V and outputs it to the first cable 50.

[0075] The second cable 52 is a cable that connects the converter 51 and the battery unit 53, and a 10-pin connector (male terminal) is provided at the tip on the battery unit 53 side.

[0076] The battery unit 53 includes an output terminal 53a connected to the second cable 52, a connection terminal 53b connected to the third cable 54, a communication control unit 53c that controls communication between the drive recorder 1, and an off-timer setting unit 53d, and a battery pack for storing electricity is mounted inside.

[0077] The third cable 54 is a cable that connects the battery unit 53 and the accessory power supply 110, and a connector 54a that can be inserted into the battery unit 53 is provided at the tip on the battery unit 53 side. As shown in FIG. 3, for example, the third cable 54 includes a GND cable 54b connected from the connector 54a to the metal part of the vehicle 100 and a power supply cable 54c connected to the accessory power supply 110 extending as separate wirings. A fuse holder 54d having a fuse mounted inside is provided in the middle of the power supply cable 54c.

[0078] As shown in FIG. 4, the power supply unit 16 configured as described above has a first cable 50 and a second cable 52, which have power lines (an example of power supply lines) 50a, 52a, GND lines 50b, 52b, a first UART line 50c, 52c (an example of a first signal line), and a second UART line 50d, 52d (an example of a second signal line). On the other hand, the connection terminal 15 does not have a terminal that receives only an input of a signal indicating the on / off state of the accessory power supply. The first cable 50 connected to the connection terminal 15, as well as the second cable 52 and the third cable 54, also do not have a signal line dedicated to transmitting a signal indicating the on / off state of the accessory power supply.

[0079] The first UART lines 50c, 52c connect the UART_TX of the connection terminal 15 of the drive recorder 1 to the UART_RX of the output terminal 53a of the battery unit 53. The second UART lines 50d, 52d connect the UART_TX of the output terminal 53a of the battery unit 53 to the UART_RX of the connection terminal 15 of the drive recorder 1. The connection terminal 15 has a power supply terminal that is electrically connected to the power line 50a, a GND terminal that is electrically connected to the GND line 50b, a first terminal that is electrically connected to the first UART line 50c, and a second terminal that is electrically connected to the second UART line 50d. The connection terminal 15 is a terminal used for UART communication.

[0080] In the power supply unit 16 configured as described above, when the accessory power supply 110 is in the ON state (start-up state), the battery unit 53 can be charged, and the power of the accessory power supply 110 can be voltage-converted via the converter 51 and supplied to the drive recorder 1. When the accessory power supply 110 is in the OFF state (non-start-up state) due to the engine stop of the vehicle 100 or the like, the battery unit 53 can supply power to the drive recorder 1 for a predetermined timer time set by the off-timer setting unit 53d. Note that the off-timer setting unit 53d is configured by, for example, a DIP switch and can set off-timer times of not used (0 hours), 0.5 hours, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, and 12 hours.

[0081] Also, the communication control unit 53c of the battery unit 53 can determine whether the connected drive recorder 1 is a communication-enabled model or a communication-disabled model by using the signal lines of the first UART lines 50c and 52c and the second UART lines 50d and 52d according to a communication processing program. A drive recorder with a communication-enabled model is a drive recorder having a function of performing communication (that is, signal transmission and reception) with the battery unit 53. For example, it is a model capable of directly exchanging the setting information of the drive recorder and signals indicating the ON state and OFF state of the accessory power supply. A drive recorder with a communication-disabled model is a model that does not have such a communication function, for example, a model that cannot directly exchange various signals.

[0082] Specifically, FIG. 5 shows a timing chart of the communication process with the drive recorder 1 executed by the communication control unit 53c. The communication control unit 53c of the battery unit 53 determines whether it is a communication-enabled model or a communication-disabled model based on whether a signal is transmitted from the drive recorder 1.

[0083] More specifically, the communication control unit 53c utilizes the fact that it is connected to the drive recorder 1 in a high impedance state. That is, as shown in FIG. 5, from the cold start of the accessory power supply 110 (at time t1), when the states (more specifically, the levels) of the first UART lines 50d and 52d, that is, the state of UART_RX of the output terminal 53a of the battery unit 53 (UART_TX of the connection terminal 15 of the drive recorder 1) are on the Hi side (high level, an example of the first state), since it is in a state where a signal regarding the drive recorder 1 (for example, a signal indicating information regarding the drive recorder 1) can be transmitted (communicated) from the drive recorder 1, it is determined to be a communication-enabled model (the upper row in FIG. 5).

[0084] On the other hand, from the cold start (at time t1) of the accessory power supply 110, if the signals on the first UART lines 50d and 52d are in the Lo state (an example of the second state) despite the high-impedance connection, since the drive recorder 1 cannot transmit a signal (for example, a signal indicating information related to the drive recorder 1), it is determined as the communication-free model (the lower part of FIG. 5).

[0085] Alternatively, the drive recorder 1 in the communication-enabled model is set to start communicating a signal related to the settings of the drive recorder 1 (in other words, a signal such as setting information) with the battery unit 53 within a predetermined time (for example, about 10 seconds) from the cold start. The communication control unit 53c may determine it as the communication-enabled model when a switching between the Hi state and the Lo state is detected on the first UART lines 50c and 52c within this predetermined time, or when a signal from the drive recorder 1 (a signal indicating communication information which is information related to communication) is received.

[0086] When the communication control unit 53c determines it as the communication-enabled model, it transmits signals corresponding to the ON and OFF of the accessory power supply 110 (hereinafter referred to as the "ON signal" and the "OFF signal" respectively; see FIG. 5) via the second UART lines 50d and 52d, thereby transmitting information regarding the ON and OFF of the accessory power supply (that is, the ON and OFF states) to the drive recorder 1. The ON signal and the OFF signal regarding the ON and OFF of this accessory power supply are transmitted when the accessory power supply 110 switches to ON or OFF. After transmitting the ON signal or the OFF signal, the second UART lines 50d and 52d return to the original state (Hi state).

[0087] On the other hand, when the communication control unit 53c determines that it is a communication-free model, it switches the states (levels) of the second UART lines 50d and 52d between the case where the accessory power is ON and the case where the accessory power is OFF. The drive recorder 1 recognizes the ON and OFF states of the accessory power according to this switching. For example, as shown in FIG. 5, when the accessory power 110 is ON, the communication control unit 53c sets the second UART lines 50d and 52d to the Hi state, and when the accessory power is OFF, the communication control unit 53c sets the second UART lines 50d and 52d to the Lo state. The drive recorder 1 can determine the ON and OFF states of the accessory power from the states of the second UART lines 50d and 52d. Note that while the accessory power 110 is OFF, the communication control unit 53c fixes the second UART lines 50d and 52d to the Lo state. In this way, the communication control unit 53c transmits the state of the accessory power 110 to the drive recorder 1 in the communication-enabled model by sending an ON signal or an OFF signal through UART_TX of the output terminal 53a, and to the communication-free model by changing the level of UART_TX of the output terminal 53a. When the drive recorder 1 is a drive recorder in the communication-free model, the controller 30 may start recording in the parking recording mode using the power supplied from the battery unit 53 in response to recognizing the OFF state of the vehicle's accessory power by switching the level input to the second terminal of the connection terminal 15. The function of the drive recorder 1 in the communication-free model to start recording in the parking recording mode in response to recognizing the OFF state of the vehicle's accessory power is a function realized by the recording processing program.

[0088] Note that, for preventing chattering, a predetermined determination period may be provided after the ON and OFF of the accessory power 110 are switched (for example, at time t2 in FIG. 5) for the switching of the ON signal and the OFF signal according to the ON and OFF of the accessory power 110 and the switching transmission of the state of UART_TX of the output terminal 53a.

[0089] [Operation] Next, an example of the operation of the switching process to the parking recording mode executed by the controller 30 of the drive recorder 1 and the communication process with the drive recorder 1 executed by the communication control unit 53c of the battery unit 53 will be described.

[0090] Next, FIG. 6 is a flowchart showing the communication process with the drive recorder 1 executed by the communication control unit 53c of the battery unit 53. Hereinafter, the communication process with the drive recorder 1 executed by the communication control unit 53c of the battery unit 53 will be described along the same flowchart. Note that the start of the flowchart in the figure is at the cold start of the accessory power supply 110, and at least the second UART lines 50d and 52d start from the Hi state (the first state).

[0091] First, in step S20, the communication control unit 53c determines whether the signals on the first UART lines 50c and 52c, that is, the signals to UART_RX of the output terminal 53a of the battery unit 53 (signals from UART_TX of the connection terminal 15 of the drive recorder 1), are on the Hi side (the first state). If the determination result is true (Yes), that is, if the first UART lines 50c and 52c are on the Hi side since the cold start, the process proceeds to step S21.

[0092] In step S21, the communication control unit 53c determines that the drive recorder connected to the battery unit 53 is a communication-enabled model capable of directly exchanging the setting information of the drive recorder and the information indicating the ON state and OFF state of the accessory power supply, and proceeds to the next step S22.

[0093] In step S22, the communication control unit 53c determines whether the accessory power supply 110 has become OFF. This is determined, for example, by whether the power supply from the accessory power supply 110 to the battery unit 53 has stopped. If the determination result is false (No), the process of step S22 is repeated until the accessory power supply 110 becomes OFF. When the determination result becomes true (Yes), the process proceeds to the next step S23.

[0094] In step S23, the communication control unit 53c transmits an OFF signal of the accessory power supply 110 from UART_TX to the drive recorder 1 via the second UART lines 50d and 52d, and ends this routine. By doing so, the drive recorder, which is a communication-enabled model, can recognize that the accessory power supply has been turned off.

[0095] On the other hand, when the determination result in step S20 is false (No), that is, when the signals on the first UART lines 50c and 52c are on the Lo side since a cold start, the process proceeds to step S24.

[0096] In step S24, the communication control unit 53c determines that the drive recorder connected to the battery unit 53 is a communication-disabled model that cannot directly exchange signals indicating the drive recorder's setting information, the ON state, and the OFF state of the accessory power supply, and proceeds to the next step S25.

[0097] In step S25, the communication control unit 53c determines whether or not the accessory power supply 110 has been turned off in the same manner as in step S22. If the determination result is false (No), the process of step S25 is repeated until the accessory power supply 110 is turned off. When the determination result becomes true (Yes), the process proceeds to the next step S26.

[0098] In step S26, the communication control unit 53c switches the output terminal 53a from the Hi state to the Lo state and ends this routine. By doing so, the drive recorder, which is a communication-disabled model, can recognize that the accessory power supply is off while the second UART lines 50d and 52d are in the Lo state. When the drive recorder 1 is a drive recorder with a communication-disabled model, the controller 30 of the drive recorder 1 may start recording in the parking recording mode using the power supplied from the battery unit 53 in response to recognizing the OFF state of the vehicle's accessory power supply by switching the level input to the second terminal of the connection terminal 15.

[0099] [Effect] When the power supply from the accessory power supply 110 of the vehicle to the battery unit 53 is cut off, the battery unit 53 switches the power supply source to the internal battery pack and supplies power to the drive recorder 1. Since power is continuously supplied to the drive recorder 1 before and after the switching, the drive recorder 1 cannot determine whether the power supply source is the accessory power supply 110 of the vehicle or the battery pack. Also, even if the drive recorder 1 does not have a function of receiving and recognizing a signal indicating that the accessory power supply 110 has been turned off from the battery unit 53, if it can recognize that the accessory power supply 110 has been turned off and determine that the parking recording start condition is satisfied and automatically start recording in the parking recording mode, the inventor considered that the convenience for the user would be improved.

[0100] Therefore, in the system of this embodiment, the drive recorder 1 is connected by a first cable and a second cable including signal lines (specifically, UART communication lines) of the battery unit 53 and the first UART lines 50c, 52c and the second UART lines 50d, 52d. And when the accessory power supply 110 of the vehicle 100 is in the OFF state, the communication control unit 53c of the battery unit 53 sends a signal indicating the OFF state of the accessory power supply 110 through the second UART lines 50d, 52d. By using the battery unit 53 connected to the drive recorder 1 and the accessory power supply 110 like this, it becomes possible to send a signal indicating the OFF state of the accessory power supply 110 to the drive recorder 1, so that even for a drive recorder 1 that cannot directly detect the OFF state of the accessory power supply 110, for example, when it is necessary to detect the OFF state of the accessory power supply 110 as in the case where the above-described parking recording start condition is the OFF state of the accessory power supply 110, it can be easily dealt with.

[0101] In particular, when signals (signals indicating setting information and the like) regarding the drive recorder 1 are not transmitted to the battery unit 53 via the UART communication lines (specifically, the first UART lines 50c and 52c), the drive recorder 1 determines that it is in a communication-free model and sends a signal indicating the OFF state of the accessory power supply 110 through the UART communication lines (specifically, the second UART lines 50d and 52d). In this way, the drive recorder 1 can identify on its own from the communication state with the drive recorder 1 that it is in a communication-free model and send a signal indicating the OFF state of the accessory power supply. For example, it is possible to suppress sending unnecessary signals to a drive recorder 1 of a communicable model.

[0102] Also, when a signal indicating predetermined communication information such as information (setting information and the like) regarding the drive recorder 1 is transmitted to the battery unit 53 via the UART communication lines (specifically, the first UART lines 50c and 52c), the drive recorder 1 determines that it is in a communication-enabled model and includes information indicating the OFF state of the accessory power supply 110 in the signal indicating the predetermined communication information. In this way, the drive recorder 1 can identify on its own from the communication state with the drive recorder 1 that it is in a communication-enabled model and send a signal indicating the OFF state of the accessory power supply using the original communication function. For example, it is possible to suppress sending unnecessary signals to a drive recorder 1 of a communicable model.

[0103] In particular, by using the first cable and the second cable capable of UART communication for the communication line, it is possible to use the existing cables without the need to newly add a special communication line.

[0104] Also, the communication processing program of the battery unit 53 of the present embodiment is a program for causing a computer to realize the above-described communication functions and the like, and can achieve the above-described effects.

[0105] When the drive recorder 1 of the present embodiment is a communication-free model, it receives the level indicating the OFF state of the accessory power supply of the vehicle via the first and second cables 50 and 52, and can recognize the OFF state of the accessory power supply of the vehicle without directly recognizing the signal related to the accessory power supply. Then, in response to recognizing the OFF state of the accessory power supply of the vehicle, this drive recorder 1 may start recording in the parking recording mode using the power supplied from the battery unit 53.

[0106] Also, if the connection terminal 15 of the drive recorder 1 is a terminal used for UART communication, such as a 10-pin mini USB terminal, for example, an existing standard terminal can be used without using a special standard terminal for the connection terminal 15. That is, the change in the hardware of the drive recorder 1 can be realized only by connecting the UART_RX line (the second terminal) of the connection terminal 15 to detect the accessory power supply and connecting the UART_TX line (the first terminal) to GND. Also, the change in the software of the drive recorder 1 can be realized only by changing the part that was switched to the parking recording mode by a touch panel or the like to start the parking recording mode by recognizing the OFF state of the accessory power supply and changing to the normal mode by recognizing the ON state of the accessory power supply.

[0107] This concludes the description of the embodiments of the present invention. However, the configurations of the above embodiments may be combined as appropriate. Also, the aspects of the present invention are not limited to this embodiment.

[0108] In the above-described embodiment, as the parking recording mode, there were two recording modes for parking, the time-lapse mode and the motion detection mode, but either one may be used, or other recording modes for parking may be added.

[0109] In the above embodiment, two imaging units, the front camera 10 and the rear camera 20, are provided in the vehicle 100, but the number and installation location of the imaging units are not limited to this. For example, an imaging unit directed to the side of the vehicle or an imaging unit for imaging the inside of the vehicle may be installed.

[0110] In the above-described embodiment, the memory card 45 has been described by taking recording media such as an SD card, a miniSD card, and a microSD card as examples. However, other recording media such as a USB memory, an SSD, and a small hard disk may also be used. Further, the memory card reader 44 can also be changed to a writing / reading device according to the recording media.

[0111] Also, the connection terminal 15 of the drive recorder 1 in the above-described embodiment is a 10-pin miniUSB. Thus, there is an advantage that the above-described embodiment can be realized without requiring new parts or the like simply by changing the connection terminal to the drive recorder with the power supply unit to a terminal having a standard such as a 10-pin miniUSB. However, the connection terminal of the drive recorder is not limited to a 10-pin miniUSB.
