  Embodiments according to the present invention will be described below in detail with reference to the drawings. The technical scope of the present invention is not limited to these embodiments, but covers the invention described in the claims and equivalents thereof. Moreover, it is also possible to implement with the form which added various change in the range which does not deviate from the meaning of this invention.

  First, information recording in the drive recorder will be described.

  FIG. 1 is a diagram showing an example in which a drive recorder 2 is mounted on a vehicle 1.

  A drive recorder 2 is installed in the vehicle 1 and is connected to a video camera 3 that captures the front of the vehicle 1 and a video camera 4 that captures the rear of the vehicle 1. Video information from the video camera 3 or the like is cyclically stored in a semiconductor storage unit in the drive recorder 2. When a predetermined recording condition is satisfied, the video information stored in the semiconductor storage unit is recorded in the memory card 6. The predetermined recording condition means a case where an impact is applied to the vehicle 1 due to the occurrence of an accident or the like, and details will be described later.

  In addition to the video information, the drive recorder 2 acquires operation information including vehicle speed information and temporarily stores it in a semiconductor storage unit in the drive recorder 2. The operation information is recorded in the memory card 6 together with the video information when the above-described recording conditions are satisfied, and the operation information stored in the semiconductor memory unit is collected every predetermined time. Recorded in the memory card 6. Details of the operation information will be described later.

  FIG. 2 is a diagram illustrating an example in which the drive recorder 2 is installed in the vehicle 1.

  The drive recorder 2 is electrically connected to the camera 3, the microphone 7, and the shooting switch 8. The camera 3 is attached to the front glass surface on the back side of the vehicle interior mirror, photographs the front of the vehicle, and transmits video information to the drive recorder 2. The microphone 7 is installed in the vicinity of the feet on the passenger seat side and collects sound in the vehicle 1. The photographing switch 8 is installed in the vicinity of the handle, and can be recorded on the drive recorder 2 by image information taken by the camera 3 (or the camera 4) when operated by the user.

  FIG. 3 is a diagram showing an example in which the main body of the drive recorder 2 is installed in the vehicle 1.

  The main body of the drive recorder 2 can be installed in the lower space of the passenger seat side seat 300. In order to record and control video information and the like when an impact or the like is applied to the vehicle 1, the main body is fixedly installed.

  FIG. 4 is a diagram illustrating an example of the appearance of a playback device.

  Video information, operation information, and the like recorded on the memory card 6 are reproduced by a reproduction device 400 configured by a personal computer or the like. The memory card 6 is inserted into an I / F connected to a personal computer, and video information, operation information, and the like are read. The user can investigate the running state of the vehicle or the cause of the accident by verifying the reproduced video information and operation information.

  FIG. 5 is a block diagram showing a functional configuration of the drive recorder 2.

  The drive recorder 2 is electrically connected to the photographing unit 500 and the speed detection unit 501, and includes an impact detection unit 502, a recording determination unit 503, and a storage unit 504. The drive recorder 2 is mounted on the vehicle 1.

  The photographing unit 500 is mounted on the vehicle 1, photographs the periphery of the vehicle, and transmits video information 505 to the storage unit 504.

  The speed detection unit 501 is mounted on the vehicle 1, detects the speed of the vehicle 1, and transmits speed information 506 to the storage unit 504.

  The impact detection unit 502 detects the impact applied to the vehicle 1 as gravity acceleration, and transmits the detected gravity acceleration information 507 to the recording determination unit 503.

  The recording determination unit 503 determines whether the magnitude of the impact detected by the impact detection unit 502 is an impact corresponding to a vehicle accident or the like. When it is determined that the vehicle corresponds to a vehicle accident or the like, the gravitational acceleration information 507 and the recording signal 508 for executing the recording control are transmitted to the storage unit 504.

  The storage unit 504 always stores the video information 505 and the speed information 506 received from the photographing unit 500 and the speed detection unit 501 cyclically. When the storage capacity reaches the limit, new video information and speed information are always stored by performing overwrite processing in order from the oldest information. When the recording signal 508 is received from the recording determination unit 503, the shock detection time information 509 including the video information 505, the speed information 506, and the gravitational acceleration information 508 is transmitted to the external recording unit 510.

  The external recording unit 510 records the impact detection time information 509 transmitted from the storage unit 504 in a nonvolatile manner. Since it is configured as a recording medium configured independently of the drive recorder 2, the impact detection time information 509 can be taken out of the drive recorder 2.

  The video display unit 511 receives the shock detection time information 509 recorded in the external recording unit 510 and displays the information as a video. Thereby, the user of the drive recorder 2 can verify the situation around the vehicle in a vehicle accident or the like with the video.

  FIG. 6 is a block diagram showing an electrical configuration of the drive recorder 2.

  The drive recorder 2 can be configured separately from the camera 3 or the camera 4 as a device dedicated to video recording. However, the drive recorder 2 is housed in the same housing as the camera 3, the camera 4 and the microphone 7 and is integrally configured. May be. Moreover, it can also be comprised as one function of a vehicle-mounted navigation apparatus.

  The camera 3 is controlled so as to photograph the front of the vehicle 1 and output an analog video signal as video information 600. For example, a CCD image sensor (Charge Coupled Device Image Sensor) or a CMOS image sensor (Complementary Metal) is used as a two-dimensional image sensor. Oxide Semiconductor Image Sensor).

  The camera 4 is installed in the vehicle 1 as a second camera, and is controlled so as to capture a different direction from the camera 3 such as the rear of the vehicle or in the passenger compartment and output an analog video signal as video information 601. If only one camera is required, it is not necessary to connect the camera 4.

  The acceleration sensor 5 is configured by a so-called G sensor (Gravity Accelerative Sensor) that detects the magnitude of an impact applied to the vehicle 1 as a gravitational acceleration. It is made of a semiconductor that generates an electric current based on the gravitational acceleration when it receives an impact, detects the magnitude of the gravitational acceleration in the longitudinal direction and the lateral direction of the vehicle, and outputs gravitational acceleration information 602 to the CPU 24.

  The memory card 6 is a recording medium that can be removed from the drive recorder 2 and includes a programmable nonvolatile semiconductor memory card such as a CF card (Compact Flash Card), an SD card (Secure Digital Memory Card), and a memory stick. The Video information and operation information are recorded in the memory card 6.

  In this embodiment, a memory card is used as a removable storage medium. However, the present invention is not limited to this, and other removable memory cards, hard disks, and the like can also be used. Further, instead of the memory card 6, the drive recorder 2 can be used with a built-in hard disk. In this case, the drive recorder 2 is provided with a transmission circuit, and the video information and operation information recorded on the hard disk by wireless communication are used. What is necessary is just to comprise so that it may transmit to the reproducing | regenerating apparatus 400. Moreover, the navigation apparatus mounted in the same vehicle as a reproducing | regenerating apparatus can be utilized. In that case, the video information and operation information recorded on the memory card 6 or the hard disk may be transmitted to the navigation device via the harness. When the navigation device is used as a playback display, only video information may be transmitted to the navigation device and displayed on the display. Thereby, when an accident occurs, the cause of the accident can be verified on the spot.

  The microphone 7 is electrically connected to the CPU 24, and is configured to collect sound inside or outside the vehicle 1 and transmit it to the CPU 24 as sound information 603. The audio information 603 is converted into a digital signal by an analog / digital converter in the CPU 24. Note that a unidirectional microphone with high sensitivity on the front side of the microphone may be used so as not to unnecessarily collect noise on the road.

  The imaging switch (imaging SW) 8 transmits a signal to the electrically connected CPU 24 when operated by the user. Thereby, the CPU 24 controls the video card information and the operation information stored in the second RAM 15 to be recorded in the memory card 6. That is, the operation of the photographing SW 8 acts as the establishment of the recording condition. Only the video information at the moment when the photographing SW 8 is operated may be recorded on the memory card 6.

  A GPS (Global Positioning System) receiver 9 receives radio signals including satellite orbits from a plurality of GPS satellites and time data from atomic clocks mounted on the satellites, and the time difference between the received radio waves By calculating the relative distance difference with each satellite, current location information is obtained. By capturing the radio waves of the three satellites, the position on the plane on the earth can be determined. When the GPS receiver 9 detects the current location information, the GPS receiver 9 transmits GPS information 604 including position information and time information to the CPU 24.

  The vehicle speed sensor 10 outputs the rotation of a rotor provided on the wheel shaft of the vehicle 1 as a rotation pulse signal 605, and is configured by a magnetic sensor or an optical sensor. Note that the CPU 24 calculates speed information of the vehicle 1 by calculating the number of wheel rotations per unit time from the pulse signal received from the vehicle speed sensor 10.

  The interface (I / F) 11 constitutes a so-called slot portion of a memory card 6 provided in the drive recorder 2. The I / F 11 transfers recording information 606 including video information and operation information transmitted from the drive recorder 2 to the inserted memory card 6.

  The video switch (hereinafter “video SW”) 12 is a switch for switching a camera to be photographed when a plurality of cameras are provided. In this embodiment, the camera 3 and the camera 4 are connected, and one camera is selected by a selection signal 607 from the CPU 24. Video information from the selected camera is output as selected video information 608. Note that the video SW 12 may be configured to have a clocking function so that switching is performed at regular time intervals.

  The image processing circuit 13 converts selected video information 608 input from the camera 3 or the like via the video SW 12 into a digital signal, and generates and outputs image data 609. For example, it is composed of JPEG-IC (Joint Photographic coding Experts Group-Integrated Circuit) and creates data in JPEG format. In this case, since JPEG-IC does not have a function of designating an address and outputting data, 30 files are written to a first RAM (Random Access Memory) 14 per second, and overwriting is performed for each file.

  The first RAM 14 temporarily stores the image data 609 converted by the image processing circuit 13. The first RAM 14 is connected to a DMA (Direct Memory Access) circuit in the CPU 24, and one out of three inputted images, that is, 10 files per second are transferred to the second RAM 15 by the DMA function and circulated. Memorized.

  The second RAM 15 cyclically stores the video information converted into image data by the image processing circuit 13 and the operation information.

  For example, SDRAM (Synchronous Dynamic Random Access Memory) is used for the first RAM 14 and the second RAM 15. Since SDRAM is designed to operate in synchronization with the CPU clock, it has a short I / O waiting time, and can be accessed faster than conventional DRAM (Dynamic Random Access Memory). This is because it is suitable for the control for processing the video data at a high speed.

  The nonvolatile ROM 16 stores a control program 17 and the like for comprehensively controlling the hardware resources constituting the drive recorder 2. A mask ROM may be used as the nonvolatile ROM 16, but a program can be written and erased by using a flash memory which is a programmable nonvolatile semiconductor memory, an EEPROM (Erasable Programmable Read Only Memory), a ferroelectric memory, or the like. It becomes possible.

  The control program 17 is stored in the non-volatile ROM 16 and is read by the CPU 24 when the drive recorder 2 is activated, and functions as a program for controlling each part and for data calculation processing.

  The indicator lamp 18 is made up of a light emitting diode or the like, and is lit while the drive recorder 2 is activated when power is supplied from the CPU 24 to notify the user that it is being activated. Further, when an abnormality occurs in the drive recorder 2, the CPU 23 notifies the user of the occurrence of the abnormality by causing the indicator lamp 18 to blink.

  The accessory switch (ACC switch) 19 is electrically integrated with an engine start key cylinder provided in the vehicle 1. When the switch is turned on by the user's key operation, an accessory on signal 610 is transmitted to the drive recorder 2. The drive recorder 2 receives the accessory on signal 610 of the ACC switch 19 and starts control. Note that an ignition key output signal can be used instead of the output signal of the ACC switch 19.

  The power switch (power SW) 20 transmits a power-on signal to the drive recorder 2 when the user performs a switch operation. This can be used when it is desired to operate the drive recorder 2 without turning on the ACC switch 17.

  The battery 21 is provided in the vehicle 1 and supplies power to the main body of the drive recorder 2. The battery supplies power to the power control circuit 22 and the backup battery 23. The battery 21 may be any battery that can be installed in a vehicle and can generate an electromotive force of 12V.

  The power supply control circuit 22 is connected to the CPU 24 and receives an ON signal from the ACC switch 19, thereby supplying power from the battery 21 to each part of the CPU 24 and the drive recorder 2. When it is detected that the power SW 20 has been operated, the power supply is started regardless of the state of the ACC switch 19. Furthermore, the power supply control circuit 22 transmits an end signal to the CPU 24 by detecting that the ACC switch 19 or the power supply SW 20 is turned off. The CPU 24 that has received the end signal transmits an off signal to the power supply control circuit 22 as a control end process. As a result, the power supply control circuit 22 stops supplying power.

  The backup battery (B / U battery) 23 is composed of a capacitor or the like, and is connected to supply power from the battery 21 to the CPU 24 and each part of the drive recorder 2. If an impact is applied to the vehicle due to a collision accident or the like, the battery 21 may be damaged, or the battery 19, the power control circuit 22, and the connection line may be disconnected. In this case, the B / U battery 23 backs up the power of the drive recorder 2 by supplying the stored power to the CPU 24 and the like.

  A CPU (Central Processing Unit) 24 operates as a control device of the drive recorder 2 and is configured by a microcomputer or the like. Based on the control program 17, the CPU 24 executes control of each part of the drive recorder 2 and data calculation processing.

  FIG. 7 is a block diagram showing an electrical configuration of the playback device 400.

  The interface (I / F) 411 configures a so-called slot portion of the memory card 6 provided in the playback device 400. The I / F 411 transfers video information, operation information, and the like recorded in the memory card 6 to the playback device 400 side.

  The RAM 414 is used to temporarily store data when the CPU 424 performs image processing of video information transferred from the memory card 6 and information processing of operation information. For example, an SDRAM is used as the RAM 414.

  The nonvolatile ROM 416 stores a control program 417 and the like for comprehensively controlling the hardware resources constituting the playback device 400. As the nonvolatile ROM 16, for example, an EEPROM, a ferroelectric memory, or the like is used.

  The control program 417 is stored in the non-volatile ROM 416, and is read out to the CPU 424 when the playback device 400 is activated, and functions as a program for controlling each unit and data calculation processing.

  The CPU 424 operates as a control device for the playback device 400 and is configured by a microcomputer or the like. Based on the control program 417, the CPU 424 executes control of each unit of the playback device 400, data calculation processing, and the like.

  The operation unit 430 includes a keyboard, a mouse, and the like, and is used as a means for performing an operation input to the CPU 424 when the user operates the playback device 400.

  The display unit 440 includes a liquid crystal display device and the like, and is used to appropriately display video information, operation information, and the like recorded on the memory card 6.

  The map information recording unit 450 is composed of a recording medium such as a hard disk or a DVD, and records map information including road information and speed limit information.

  The card information recording unit 460 is configured by a recording medium such as a hard disk and is used for recording video information, operation information, and the like recorded on the memory card 6.

  Next, a recording procedure for video information and operation information in the drive recorder 2 will be described.

  The CPU 24 alternately acquires still image data captured by the cameras 3 and 4 at a rate of 10 frames per second (that is, a still image from the camera 3 is captured every 0.2 seconds. Are alternately obtained at intervals of 0.2 seconds), and are cyclically recorded in the second RAM 15 via the first RAM 14. Further, the CPU 24 acquires operation information and records it cyclically in the second RAM 15 every time still image data is acquired by the cameras 3 and 4. Further, the CPU 24 periodically stores operation information in the second RAM 15 separately from the acquisition timing of the still image data. The time interval and the number of still image data acquired by the CPU 24 described above are examples, and the present invention is not limited to this.

  Next, when the CPU 24 detects the establishment of a recording condition to be described later, video information for a total of 30 seconds, 15 seconds before the recording condition is established and 15 seconds after the establishment of the recording condition (300 still images each time the recording condition is established). The operation information is transferred from the second RAM 15 to the memory card 6 and recorded. Since the video information, operation information, and the like recorded in the memory card 6 can be displayed on the playback device 400, the user of the drive recorder 2 can verify the running state and accident situation of the vehicle 1. . Note that the above-described period (15 seconds before the recording condition is satisfied and 15 seconds after the recording condition is satisfied) that the CPU 24 records on the memory card 6 when the recording condition is satisfied is an example, and the present invention is not limited to this.

  In addition, the CPU 24 transfers operation information stored every second in the operation information stored in the second RAM 15 from the second RAM 15 to the memory card 6 and records it every 10 seconds independently of the establishment of the recording condition. To do. That is, the operation information every 1 second is recorded in the memory card 6 every 10 seconds irrespective of the establishment of the recording condition described later. In addition, the interval of the operation information recorded by the CPU 24 and the recording timing to the memory card 6 are examples, and are not limited thereto. The reason why the operation information is recorded in the memory card 6 every 10 seconds is that if the recording is performed every second, the memory card is frequently accessed and an overhead may occur. Further, when the CPU 24 detects the establishment of the dangerous driving condition for detecting the dangerous driving different from the recording condition, the CPU 24 stores the operation information at the time of detection and the event data indicating the type of the dangerous driving condition established in the memory card 6. Record. The operation information per second and the operation information indicating dangerous driving are also used as violation items described later.

  The case where the recording condition is satisfied means the following three cases.

1. G detection: When the acceleration sensor 5 detects gravitational acceleration equal to or greater than a predetermined threshold. Specifically, when the gravitational acceleration in the front-rear direction of the vehicle 1 is Gy and the gravitational acceleration in the left-right direction of the vehicle 1 is Gx, the CPU 24 outputs the absolute value (Gx ² + Gy ²⁾ of the combined gravitational acceleration output from the acceleration sensor 5. ) 0 ^{- 5} was detected every 10 ms, the value of the threshold value or more acceleration, when it is detected continuously threshold duration or more, it is determined that the recording condition is established. The threshold acceleration can be set to 0.40 G, and the threshold duration can be set to 100 milliseconds. The reason why the recording condition is satisfied is that it can be recognized that a collision accident of the vehicle 1 has occurred. Details of the setting will be described later.

    2. Speed trigger: When the speed difference within a predetermined period of the vehicle 1 detected from the vehicle speed sensor 10 is equal to or greater than a threshold value. Specifically, when traveling at 60 km / h or more and the deceleration for one second becomes 14 km / h or more, it is determined that the recording condition is satisfied. The reason why the recording condition is satisfied is that when the vehicle 1 undergoes such a speed change, it can be recognized that an accident has occurred or that the accident is imminent. Details of the setting will be described later.

    3. Shooting SW: When shooting SW8 is operated.

  When any one of the above recording conditions is satisfied, the CPU 24 transfers video information and operation information for a total of 30 seconds, 15 seconds before and 15 seconds after the recording conditions are satisfied, from the second RAM 15 to the memory card 6 for recording. It becomes. When the recording condition is satisfied, event data indicating the satisfied recording condition (data indicating one of the above three) is recorded together on the memory card 6. When the recording condition is satisfied, the audio information acquired from the microphone 7 is recorded on the memory card 6 together with the video information for a total of 30 seconds, 15 seconds before and 15 seconds after the recording condition is satisfied. You may comprise.

  The operation information is the following information.

    1. Gravity acceleration information (Gy, Gx) detected from the acceleration sensor 5.

    2. Position information and time information of the vehicle 1 detected from the GPS receiver 9.

    3. Speed information detected from the vehicle speed sensor 10.

    4). ON / OFF information of the ACC switch 19.

  Note that the content of the operation information is not necessarily limited to the information described above, and may include information related to the operation and traveling of the vehicle 1 such as the lighting state of lights such as a blinker and the steering angle of the steering wheel. good.

  In addition, the memory card 6 is separately recorded with the recording conditions, the unique ID of the memory card 6, the ID of the user (for example, taxi crew, etc.) or the name data using the memory card 6. To do. As described above, the condition for recording an image is referred to as “recording condition”, the condition for recording only operation information is referred to as “dangerous driving condition”, and both conditions are collectively referred to as “trigger condition”.

  Next, display of information in the playback apparatus 400 will be described.

  FIG. 8 is a diagram showing an example of a menu screen in the playback apparatus 400.

  When the playback apparatus 400 is turned on, the first screen 100 is displayed on the display unit 440 and five menu items 101 to 105 are displayed. When the “change recording condition setting” item 104 is selected by the operation unit 430 on the first screen 100, the four items shown in the second screen 110 are displayed, and the “eco-safe driving analysis” item 105 is displayed on the operation unit 430. When selected, two items shown in the third screen 120 are displayed. When the “change determination level setting” item 123 is selected on the third screen 120, four items shown on the fourth screen 130 are displayed. Details of each item will be described later.

  FIG. 9 is a diagram illustrating a flow of an operation example of the memory card 6.

  First, the user selects the “initialize memory card” item 101 on the first screen 100 shown in FIG. 8 on the playback device 400, inserts the memory card 6 to be used into the I / F 411 of the playback device 400, and loads the card. Initialization is performed (S1). In the initialization of the card, the data previously recorded on the memory card 6 is deleted by the CPU 424, and trigger conditions such as newly set recording conditions and dangerous driving conditions, which will be described later, and the memory card 6 are used. The ID of the user (for example, a taxi crew member) who operates is written in a predetermined address of the memory card 6.

  Next, the user places the initialized memory card 6 in the vehicle 1 at the start of operation of the vehicle 1 (for example, when a taxi crew member starts day shift work (7:45 to 17:15)). It is inserted into the I / F 11 of the drive recorder 2 and data recording is started (S2). When the memory card 6 is inserted into the I / F 11 of the drive recorder 2, the trigger condition recorded in the memory card 6 is read out by the CPU 24 and recorded in the second RAM 15 or the like, and the CPU 24 is newly set. Whether or not the recording condition is satisfied is determined based on the trigger condition. As described above, the CPU 24 records video information and operation information for a predetermined period (for example, 30 seconds) on the memory card 6 when the recording condition is satisfied, and is satisfied when the dangerous driving condition is satisfied. The operation information at the time is recorded in the memory card 6. Further, the CPU 24 records operation information for each predetermined period (for example, 1 second) in the memory card 6 every predetermined period (for example, 10 seconds).

  Next, when the operation of the vehicle 1 ends (for example, when a taxi crew member ends the day shift work), the memory card 6 for which data recording has been completed is taken out from the I / F 11 of the drive recorder 2. Further, the user selects the “read memory card” item 102 on the first screen 100 shown in FIG. 8 on the playback device 400, inserts the memory card 6 into the I / F 411 of the playback device 400, and records it on the memory card 6. The read video information, operation information, trigger conditions, memory card ID, user ID, and the like are read into the playback device 400 (S3).

  On the playback device 400 side, the CPU 424 reads the video information, operation information, trigger conditions, memory card ID, and user ID recorded in the memory card 6 corresponding to one operation of one vehicle. In the playback device 400, it is also possible to individually analyze data for each memory card, and after reading data corresponding to a plurality of operations of a plurality of vehicles from the plurality of memory cards 6, the data analysis is summarized. It is also possible to do this. Further, one memory card 6 may be used for a plurality of vehicles or used for a plurality of operations.

  FIG. 10 is a diagram showing an example of a screen for displaying video information recorded on the memory card 6. Note that the CPU 424 executes display processing for all screens described later including FIG. 10 and processing based on user operations on the screens.

  A screen 140 shown in FIG. 10 is displayed when the user selects the “image display” item 103 on the first screen 100 shown in FIG. 8 on the playback device 400, and the CPU 424 follows the control program 417 to display the card information storage unit. Based on the data stored in 460, the data is displayed on the display unit 440.

  As shown in FIG. 10, on the screen 140, the ID number data 141 of the memory card 6, the time information 142 included in the operation information, the type information 143 indicating the established recording condition, the latitude data 144 in the position information, the position Longitude data 145 in the information, detection G information 146 indicating the absolute value of the combined gravitational acceleration, recording condition information 147 when the displayed image is taken, and an area 148 for sequentially displaying still images taken by the camera 3 -1, an area 148-2 for sequentially displaying still images captured by the camera 4, operation buttons 149 (rewind, play, stop, fast forward) for controlling still images captured by the cameras 3 and 4 are displayed. Has been. The detected G information 146 indicating the absolute value of the combined gravitational acceleration is the acceleration sensor 5 included in the operation information detected when the CPU 424 captures the images displayed in the areas 148-1 and 148-2. Based on the gravitational acceleration information (Gy, Gx) detected from the above, it is calculated and displayed. That is, the dynamic acceleration when the recording condition is established by G detection is shown.

  On the screen 140 shown in FIG. 10, when the user controls the operation button 149, 150 still images captured by the camera 3 for 15 seconds and 150 still images captured by the camera 4 for 15 seconds are displayed. The display areas 148-1 and 148-2 are displayed while being sequentially switched. At the same time, information corresponding to the displayed still image is displayed in the display / input areas 141 to 147. Note that the screen 140 illustrated in FIG. 10 is an example, and other screen configurations can be selected.

  In the present embodiment, as shown in FIG. 10, by displaying the recording condition corresponding to the displayed still image on the same screen as the still image, it is easy to check whether the recording condition is appropriate while viewing the image. Can be judged. If it is determined that the recording condition is inappropriate, the recording condition setting described later may be changed. Thereby, it is possible to change the setting of appropriate recording conditions.

  In FIG. 10, the recording condition and the image are displayed on the same screen. However, it is not always necessary to display both on the same screen. For example, an operation button for displaying the recording condition is displayed on the same screen as the image. The recording condition may be displayed as a separate window when the operation button is operated. This configuration increases the number of operations for operating the operation buttons, but it does not change that it can be easily determined whether or not the recording conditions are appropriate.

  Next, the setting change of the recording condition will be described.

  Of the above-mentioned three recording conditions, for G detection and speed trigger, it is possible to optimize the recording condition in accordance with the situation by changing the threshold value and / or the set value. it can. For example, if the threshold level is increased, video information is recorded when only a serious accident or the like occurs, but there is a possibility that the video information is not recorded in a minor accident. On the other hand, if the threshold level is lowered, video information is recorded even if sudden acceleration / deceleration that does not lead to an accident occurs, and only unnecessary video information may be recorded. . Therefore, in the embodiment of the present invention, a procedure for appropriately changing the recording condition is provided.

  In FIG. 10, the recording condition 147 is shown together with the detection G 146 when the playback apparatus 400 changes the recording condition setting such as the G detection value and the recording of the detection G and the like initially set in the memory card. This is because the timing of image recording may differ depending on the set value of the condition.

  For example, it is assumed that the value of the detection G is increased from 0.40 G to 0.06 G while examining various images in the playback device 400. However, it is conceivable that many memory cards 6 are already loaded in the drive recorder 2 of each vehicle and image recording is executed at the time of setting change. In such a case, when data is transmitted and recorded from the memory card 6 that has performed image recording without changing the recording conditions (that is, the detection G is 0.40 G) to the playback device 400, the playback device 400 side In spite of changing the recording condition setting, there is a risk of misunderstanding due to the image recording being performed under the low detection G condition. Therefore, for example, by displaying the recording condition 147 on the display screen shown in FIG. 10, it is possible to eliminate such misunderstandings.

  In other words, the playback apparatus 400 side intends to perform image recording under the condition in which the recording condition was last changed, but actually the image recording is performed in a state before the condition is changed during that time. In some cases, it is significant to display the recording condition 147 in order to ensure consistency at that point.

  FIG. 11 is a diagram illustrating an example of a recording condition setting change flow.

  First, when the user selects the “image display” item 103 on the first screen shown in FIG. 8, the operation is detected by the CPU 424, and the CPU 424 reproduces the video information together with the recording conditions (S4).

  When the user determines that video information relating to only a serious accident is recorded or a large amount of unnecessary video information is recorded, it is determined that the recording conditions at that time are inappropriate, as shown in FIG. In the first screen 100, the “change recording condition setting” item 104 is selected. Then, the operation is detected by the CPU 424, and the second screen 110 shown in FIG. 8 is displayed on the display unit 440 by the CPU 424. Further, when the user selects each item 111 to 114 shown on the second screen 110, the operation is detected by the CPU 424, and a detailed setting value of the recording condition is displayed on the recording condition setting screen described later by the CPU 424. (S5). In the second screen 110, a “G detection” item 111, a “speed change condition” item 112, and a “rolling correction” item 113 are setting change items related to G detection of the recording condition described above. However, it is not necessary to change all three settings. The “speed trigger” item 114 is a setting item related to the speed trigger of the recording condition described above.

  As a result of examining the setting value of the recording condition, when the user determines that the setting value needs to be changed, an operation for changing the setting value is performed on the recording condition setting screen. When the CPU 424 detects the change operation (S6), the CPU 424 can change the set value according to the operation (S7) and save the change (S8).

  FIG. 12 is a diagram illustrating a G detection setting screen example (1).

  When the user selects the “G detection” item 111 on the second screen 110, a screen 150 shown in FIG. 12 is displayed on the display unit 440.

  On the screen 150, a graph is shown in which the threshold acceleration (0.3 to 0.6 G) is shown on the Y axis and the threshold duration (80 to 200 milliseconds) is shown on the X axis. In the graph, two settings of the violation G trigger 151 and the accident impact G trigger 152 set at the present time are displayed. The threshold acceleration of the violation G trigger 151 is shown in the display / input area 153, and the threshold duration is shown in the display / input area 154. Further, the threshold acceleration of the accident impact G trigger 152 is shown in the display / input area 155, and the threshold duration is shown in the display / input area 156. Since the numerical value of the accident collision G trigger 152 does not exist on the graph, it is temporarily displayed at the upper left corner of the graph.

  The violation G trigger 151 and the accident impact G trigger 152 shown on the screen 150 correspond to specific setting values for the G detection of the recording condition described above. Here, in consideration of the size of the vehicle 1, the detection condition of the acceleration sensor 5, and the like, two types of setting values related to G detection are provided, but one type of setting value may be used.

  The user can easily change the setting of the violation G trigger by, for example, clicking the violation G trigger 151 displayed on the graph with the mouse and holding it to another position on the graph. The setting values of the display / input areas 153 and 154 are changed in accordance with the change of the position of the violation G trigger 151 on the graph. The same applies to the accident impact G trigger 152. It is also possible to change the setting of each G trigger by directly inputting set values into the display / input areas 153 to 156. In this case, the positions of the triggers 151 and 152 on the graph automatically change according to the values input in the display / input areas 153 to 156.

  In FIG. 12, the indicator of the detection level of the violation G trigger is divided into three stages and displayed on a graph as a guideline for setting. That is, when the detection level is low, “△” 50 is displayed at a location of 0.35 G, 100 milliseconds, and when the detection level is at “□” 51, it is displayed at a location of 0.4 G, 100 milliseconds. When the detection level is high, “x” 52 is displayed at a location of 0.45 G, 100 milliseconds. These guidelines allow the user to change the settings so that the desired detection level is achieved.

  FIG. 13 is a diagram illustrating a G detection setting screen example (2).

  A screen 150 ′ shown in FIG. 13 shows a state in which the violation G trigger 150 on the graph is moved to the violation trigger 150 ′ with a mouse. Further, the display contents of the display / input areas 153 and 154 of the violation G trigger change with the movement to the violation G trigger 150 '.

  In addition, by selecting “Reset” 157 on the screen of FIG. 12 and FIG. 13, all the set numerical values are reset, and by selecting “Save Settings” 158, the set recording conditions are saved. By selecting “Close” 159, the screen is switched to return to the first screen 100 shown in FIG. 8.

  As shown in FIGS. 12 and 13, since the numerical value can be determined two-dimensionally and visually, it is possible to easily and appropriately change the specific setting of the G detection.

  FIG. 14 is a diagram showing a speed change condition screen example (1).

  When the user selects the “speed change condition” item 112 on the second screen 110, a screen 160 shown in FIG. 14 is displayed on the display unit 440.

The screen 160 displays a graph in which the threshold acceleration (0.0 to 1.0 G) is shown on the Y axis and the vehicle speed (0 to 150 km / h) is shown on the X axis. The graph first violation G trigger 161 the speed of the vehicle is up to _V 1 miles / h, the second violation G trigger 162 the speed of the vehicle is up to _V 1 _~V 2 km / h, and the speed of the vehicle A third violation G trigger 163 greater than or equal to V ₂ km / h is shown. The violation G trigger set on the G detection screen 150 shown in FIG. 12 is set as the first violation G trigger 16 here.

  That is, on the screen 160, it is possible to set the value of the violation G trigger in accordance with the change in the vehicle speed. The violation G trigger is set according to the change in the vehicle speed when the vehicle speed becomes high, a large G is applied to the vehicle by a brake operation or a handle operation, and it is not an accident. This is because there is a risk that

In the screen 160, sets the _{V 1} 60 km / h, the _{V 2} to 100km / h, is set a second violation G trigger 0.50 g, the third violation trigger to 0.6G.

As for the vehicle speeds V ₁ and V ₂ , the straight lines 164 and 165 on the graph may be moved in the horizontal direction in the drawing with a mouse, or predetermined numerical values may be input to the areas 166 and 168. In addition, when either changes, a display changes so that the other may change according to a change.

  The second violation G trigger and the third violation G trigger may move the straight lines 162 and 163 on the graph in the vertical direction in the drawing with the mouse, or input predetermined numerical values in the areas 167 and 169. You may change it as you do. In addition, when either changes, a display changes so that the other may change according to a change. Of course, the first violation G trigger may be similarly changed on this screen.

  FIG. 15 is a diagram showing a speed change condition setting screen example (2).

  In the screen 160 ′ shown in FIG. 15, the second violation G trigger 162 is moved to the violation trigger 162 ′ with the mouse and the third violation G trigger 163 is moved to the violation trigger 163 ′ with the mouse on the graph. Show. In addition, the display contents of the areas 167 and 169 change with the movement of the violation G trigger.

  The functions of “Reset”, “Save Settings”, and “Close” on the screens of FIGS. 14 and 15 are the same as those in FIG.

  As shown in FIGS. 14 and 15, since the numerical value can be determined in other stages and visually, it is possible to easily and appropriately change the specific setting of the G detection.

  FIG. 16 is a diagram showing a roll correction setting screen example (1).

  When the user selects the “rolling correction” item 113 on the second screen 110, a screen 170 shown in FIG. 16 is displayed on the display unit 440.

  On the screen 170, a roll detection level 171 and a display / input area 172 of the roll detection level are displayed. The standard value of the rolling detection level is set to 0.10G. As described above, the acceleration sensor 5 detects the gravity acceleration in the front-rear direction of the vehicle 1 as Gy and the gravity acceleration in the left-right direction of the vehicle 1 as Gx. However, since Gx is felt low in terms of experience, the Gx is actually large, and although the crew member does not feel that a large acceleration is applied to the vehicle, the recording conditions such as detection G are satisfied. There is.

  Therefore, a predetermined numerical value is negatively set from the actual detection result in advance so that the experience and the case where the actual recording condition is satisfied are matched. Specifically, the resultant gravitational acceleration is calculated after being subtracted from the measured value Gx by the numerical value set on the screen 170. For example, since 0.10 G is set on the screen 170, Gx is converted to (Gx-0.01) and processed thereafter.

  The roll sensitivity level can be changed by moving the roll detection level 171 on the graph in the horizontal direction in the drawing with a mouse, or by inputting a predetermined numerical value in the area 172. When either changes, the display changes so that the other changes according to the change.

  FIG. 17 is a diagram showing a roll correction setting screen example (2).

  A screen 170 ′ shown in FIG. 17 shows a state in which the roll detection level 171 is moved to the roll detection level 171 ′ with the mouse on the graph. Further, the display content of the region 172 changes with the movement of the rolling detection level.

  The functions of “Reset”, “Save Settings”, and “Close” on the screens of FIGS. 16 and 17 are the same as those in FIG.

  As shown in FIGS. 16 and 17, since the numerical value can be determined visually, it is possible to easily and appropriately change the specific setting of the G detection.

  FIG. 18 is a diagram showing a speed change trigger setting screen example (1).

  When the user selects the “speed change trigger” item 114 on the second screen 110, a screen 180 shown in FIG. 18 is displayed on the display unit 440.

  The screen 180 displays a graph in which the speed of the vehicle (0 to 100 km / h) is shown on the Y axis and the passage of time is shown on the X axis. The graph shows a set speed 181 and a change amount 182, and the screen 180 further shows a set speed display / input area 183 and a change amount display / input area 184.

  That is, on the screen 180, when the speed of the vehicle is a set speed of 60 km / h or more, a speed change trigger of -14 km / h is set as a speed change trigger within one second. Show. When such a speed change occurs, it can be determined that there is a high possibility that an accident or the like has occurred.

  As for the set speed and change amount, straight lines 181 and 182 on the graph may be moved in the vertical direction in the drawing with a mouse, or predetermined numerical values may be input to the display / input areas 183 and 184. In addition, when either changes, a display changes so that the other may change according to a change.

  In the graph, an index 185 when the detection level is low, an index 186 when the detection level is medium, and an index 187 when the detection level is high are also shown. When the user changes the setting, It is configured to be a guide.

  FIG. 19 is a diagram showing a speed change trigger setting screen example (2).

  A screen 180 ′ shown in FIG. 19 shows a state in which the change amount 182 is moved to the change amount 182 ′ with the mouse on the graph. In addition, the display content of the display / input area 184 changes as the change amount 182 moves.

  The functions of “Reset”, “Save Settings”, and “Close” on the screens of FIGS. 18 and 19 are the same as those in FIG.

  As shown in FIGS. 18 and 19, since the numerical value can be determined in other stages and visually, it is possible to easily and reliably change the specific setting of the speed change trigger.

  As described above with reference to FIGS. 12 to 19, when the video information is confirmed and the recording condition seems to be inappropriate, the recording condition, that is, the above-described G detection and speed change trigger, It became possible to easily and appropriately change the setting of conditions.

  In the above embodiment, the reproduced image shown in step S4 of FIG. 10 and FIG. 11 and the recording conditions are displayed together, and the recording conditions shown in steps S5 to S8 of FIG. 12 to FIG. 19 and FIG. Although a description has been given of a combination of forms for changing settings on the graph, in the present invention, each form constitutes an independent invention.

  Next, user rankings and vehicle traces using operation information will be described.

  The ranking of the user means that various users determine the driving status of the user from the event data or operation information recorded in the memory card 6 according to the following six violation items, and perform ranking. Further, the vehicle trace means that, based on the operation information recorded on the memory card 6 by the user, the situation in which the user's vehicle has moved is displayed on the map in time series.

  Below, 6 violation items which judge a user's driving condition are shown.

    1. Overspeed: A case where the vehicle is driven for a predetermined time (for example, 10 seconds) at a speed higher than a predetermined speed (for example, 80 km / h). “Overspeed” is recorded in the memory card 6 as event data when the drive recorder 2 detects that the overspeed condition set as one of the dangerous driving conditions is satisfied. Therefore, whether the speed is exceeded is determined based on the event data read from the memory card 6.

    2. Rapid acceleration: A case where the speed increases for a predetermined time (for example, 1 second) or more by a predetermined increase value (for example, 13 km / h). The rapid acceleration is recorded in the memory card 6 as event data when the drive recorder 2 detects that the rapid acceleration condition set as one of the dangerous driving conditions is satisfied. Therefore, whether or not the acceleration is rapid is determined based on the event data read from the memory card 6.

    3. Rapid deceleration: A case where the speed is decreased by a predetermined decrease value (for example, 13 km / h) or more during a predetermined time (for example, 1 second). The sudden deceleration is recorded in the memory card 6 as event data when the drive recorder 2 detects that the sudden deceleration condition set as one of the dangerous driving conditions is satisfied. Accordingly, whether or not the vehicle is suddenly decelerated is determined based on the event data read from the memory card 6.

    4). Steep steering: A case where the gravitational acceleration Gx in the left-right direction of the vehicle 1 is equal to or greater than a predetermined detection value (for example, 0.45 G) for a predetermined time (for example, 500 milliseconds). The sudden handle is recorded in the memory card 6 as event data when the drive recorder 2 detects that the sudden handle condition set as one of the dangerous driving conditions is satisfied. Accordingly, whether or not the handle is a sudden handle is determined based on the event data read from the memory card 6.

    5. Idling: A case where the state where the ACC switch is ON and the speed is 0 km / h continues for a predetermined time (for example, 5 minutes) or longer. The idling is determined based on the output of the ACC switch 19 and the speed information detected from the vehicle speed sensor 10.

    6). Long-time operation: A case where the output of the ACC switch 19 has not been turned OFF for a predetermined time (for example, 2 hours) or longer. The long-time operation is determined based on the output of the ACC switch 19 among the operation information recorded every second in the drive recorder 2. Note that overspeed, rapid acceleration, rapid deceleration, and sudden steering may be determined based on operation information recorded every second.

  The situation corresponding to the above six violation items is an act of driving dangerously (being violation items 1 to 4 above) or a factor that exacerbates environmental problems (violation items 5 and 6 above). . Therefore, when the user is using the vehicle (during driving), it is determined whether or not the above six violation items have occurred, and if they occur, the score corresponding to each item is deducted from a maximum of 100 points. In this way, the ranking of the user can be displayed on the display device 440 of the playback device 400. The display of the user ranking is executed by the CPU 424 in accordance with the control program 417 based on the data recorded in the card information recording unit 460. It should be noted that the violation items to be considered when ranking are not necessarily all the above-described six items, and may be configured so that they can be selected from the six items as necessary.

  FIG. 20 is a diagram illustrating a flow from user ranking to vehicle tracing.

  The CPU 424 executes the flow shown in FIG. 20 in cooperation with each element in the playback device 400 based on the control program 417. When the flow shown in FIG. 20 is started, the playback device 400 is turned on, each element is in an operable state, and the card information storage unit 460 has a memory card 6 operated by a plurality of users. Is already recorded.

  First, the user operates the operation unit 430 to select the “eco-safe driving analysis” item 105 on the first screen 100, display the third screen 120, and further select the “ranking” item 121. Then, the ranking display screen 200 shown in FIG. 21 is displayed on the display unit 440.

  Next, an appropriate numerical value is entered in the selection of the due date designation item 201 and / or the target date 202 item on the screen 200, and the “search” item 203 is selected (S20).

  Then, the users whose data are stored are displayed in the ranking display column 212 of the screen 210 of FIG. 22 in descending order of comprehensive evaluation during the period specified in S20 (S21). As described above, the overall evaluation is based on whether or not the vehicle has been operated in accordance with “Overspeed”, “Rapid acceleration”, “Rapid deceleration”, “Rapid steering wheel”, “Rapid idling” and “Long driving”. Judgment is made based on operation information including event information of each user. The ranking display column 212 includes comprehensive evaluation, rank, number of violations, travel distance, crew time, maximum speed (general road), maximum speed (highway), average speed, total travel distance, total crew time, driving tendency, and the like. Is displayed.

  Next, a specific user, for example, user A (212) is selected from the users displayed in the ranking display column 212 (S22).

  Then, for the user selected in S22, the violation details made during the period specified in S21 are displayed in the violation details display field 221 of the screen 220 shown in FIG. 23 (S23). The violation means any one of the above-described six evaluation items, and the date and time when the violation was committed and the violation type (that is, any one of the six evaluation items) are displayed.

  Next, when a predetermined violation, for example, violation 222 is selected in the violation detail display field 221, (S24), the trace display of the vehicle from 1 hour before the occurrence of the selected violation to 1 hour after the occurrence is shown in FIG. Is displayed in the trace display field 231 on the screen 230 shown (S25).

  In the vehicle trace screen 230 shown in FIG. 24, a column 232 indicating marks for violation items (overspeed, sudden acceleration, sudden deceleration, sudden steering wheel and idling), recording conditions (G detection, speed trigger, operation SW), Displays control buttons 233 for moving, rewinding, fast-forwarding, pausing, etc. in time series, “parameter OFF” item 234, “speed chart” display item 235, “print” item 236, “close” item 237, etc. Is done.

  In the trace display column 231, a vehicle movement path 240, vehicle position plots 241 to 246, and violation item marks 247 to 249 are displayed. The vehicle position plots 241 to 246 include information on a traveling direction arrow, a vehicle existence time (hour, minute, second), and a vehicle speed. Note that the vehicle position plot is arranged and displayed on the map extracted from the map information recording unit 450 based on the vehicle position information detected from the GPS receiver 9 included in the operation information. The traveling direction arrow is obtained from the relationship between the vehicle position information included in the previous vehicle position plot and the vehicle position information included in the current vehicle position plot. Accordingly, the vehicle movement path 240 is displayed so as to connect the vehicle position plots.

  In the trace display column 231 of FIG. 24, the violation 222 (15:17:12 rapid acceleration) selected in the violation detail display column 221 shown in FIG. 23 is shown as a vehicle position plot 246, indicating a mark indicating rapid acceleration. 249 is also displayed. Thus, in the vehicle position plot shown in the column 232, the violation items (excessive speed, sudden acceleration, sudden deceleration, sudden steering wheel and idling) and the recording conditions (G detection, speed trigger, operation SW) must be included. The corresponding mark is also displayed. As described above, since the vehicle position plot and the mark indicating the violation item and the recording condition are displayed together, it is possible to easily and easily grasp where and how the driving state is on the route.

  In the trace display column 231, only five points before the occurrence of the violation 222 are displayed for convenience, but actually, a vehicle position plot for 1 hour before and after the occurrence of the violation 222 can be displayed. In addition, the said period (1 hour before and after violation occurrence) of the vehicle position plot displayed on the basis of the selected violation is an example, and another value can also be selected.

  In FIG. 24, when the “speed chart” item 235 is selected, the speed chart of the vehicle displayed in the trace display field 231 can be displayed.

  FIG. 25 is a diagram illustrating an example of a speed chart display screen.

  On the screen 250, operation date data 251, user data 252, first speed chart display field 253, second speed chart display field 254, “close” item 255, and the like are displayed. In the first speed chart display field 253, the vehicle speed is plotted on the vertical axis and the time is plotted on the horizontal axis, and the vehicle speed at each time is plotted based on the speed information detected from the vehicle speed sensor 10 included in the operation information. Has been. In the second speed chart 254, the vertical axis indicates distance (5 km) and the horizontal axis indicates time, and displays how much the vehicle has traveled at each time. That is, in the second speed chart 254, the shorter the vertical line width, the longer the travel distance per unit time. In addition, although the speed chart for 8 hours from PM14 to PM22 is shown on the screen 250, this is an example, and the display is not limited to the display for 8 hours.

  As described above with reference to FIGS. 20 to 25, based on the ranking of the user, the vehicle trace, and the speed chart using the operation information, the user's running status of the memory card 6 can be easily grasped. It became possible to do.

  Next, conditions for violation items, that is, setting changes for dangerous driving conditions will be described.

  The embodiment of the present invention is configured so that the condition setting of each of the six violation items used when ranking is performed can be changed. That is, on the third screen 120 shown in FIG. 8, if the “change judgment level setting” item 122 is selected, the fourth screen 130 is displayed. By selecting each item, four of the six violation items are displayed. The settings can be easily changed. The other two violation items may be configured so that their settings can be changed similarly.

  FIG. 26 is a diagram showing an example of the overspeed setting screen (1).

  When the user selects an “overspeed” item 131 on the fourth screen 130, a screen 260 shown in FIG. 26 is displayed on the display unit 440.
