Description

  The present invention relates to a recording control system that performs control for recording vehicle behavior information, a display control system that displays recorded vehicle behavior information, and a program.

  In-vehicle recording devices, such as drive recorders (including those called event data recorders), which record peripheral images and vehicle speeds when an impact is applied to the vehicle due to sudden braking, sudden steering or collision, etc., have become popular Yes. By providing such a drive recorder in a vehicle, when an accident occurs, it is possible to verify the cause of the accident by analyzing the recorded information.

  It also collects camera images, vehicle speeds, and driving information such as GPS (Global Positioning System) position information recorded by drive recorders mounted on commercial vehicles such as trucks and taxis. There is a driving support device that checks the content and analyzes how each crew member operates and uses it for driving training for crew members. Such a driving assistance device can improve the driver's awareness of safe driving, and can use the video recording the daily driving situation for safety driving guidance and the like.

  The drive recorder described in Patent Document 1 does not start recording new video information when a new recording condition is satisfied within a predetermined period after the recording condition is satisfied. In addition, after the recording condition is satisfied, when a new recording condition is satisfied during the video information recording period longer than the predetermined period, the video information recording time is extended. This prevents the same video information from being repeatedly recorded on a recording element having a limited capacity when recording conditions are continuously established within a short time.

  In the drive recorder described in Patent Document 2, when a new recording condition is satisfied after a lapse of a predetermined period after the recording condition is satisfied, the video data recording start time when the new recording condition is satisfied is If it is before the recording end time due to the establishment of the recording condition, the video data recording time due to the establishment of the previous recording condition is extended to the recording end time due to the satisfaction of the new recording condition. As a result, even when the recording condition is satisfied continuously within a predetermined time, the video data can be continuously recorded without missing.

Japanese Patent No. 4439549 International Publication No. 2007/066663

  In the drive recorder described in the above-mentioned Patent Document 1, if a new recording condition is satisfied after the recording condition is satisfied and then the video information recording period is completed, the recording is performed as a separate recording data file. The For this reason, there is a problem that a new data file is recorded each time a new recording condition is satisfied, and the number of data files increases each time. In addition, when new recording conditions are established within a predetermined period after the recording conditions are established, recording of video information is not newly started. There is a risk of recording unsatisfactory video information.

  Further, in the drive recorder described in the above-mentioned Patent Document 2, if the video data at the time when the new recording condition is satisfied is the data that the user really wants than the video data at the time when the previous recording condition is satisfied, Since there is little information used to specify when the recording conditions are established, for example, in the above driving support device, the operation manager or the like searches for the establishment times of a large number of recording conditions, and from among them the specific recording conditions When trying to find the time when the recording condition is satisfied, there is a problem that it is difficult to search for the time when the new recording condition is satisfied and it is difficult to find the data that is really desired.

  The present invention has been made in view of the above-described circumstances and the like, and is a recording control capable of easily specifying the vehicle behavior information required by itself from the vehicle behavior information over a series of periods. It is an object of the present invention to provide a display control system capable of easily specifying a vehicle behavior required by itself from the system and vehicle behavior within a predetermined period.

  In a first aspect, the present invention performs control for associating and recording vehicle behavior information over a predetermined period of time and information for specifying that can specify a point in time when the predetermined condition is satisfied when a predetermined condition is satisfied. In the recording control system, there is an overlap between the already recorded vehicle behavior information over the first period and the vehicle behavior information over the second period recorded when the predetermined condition is newly satisfied. In this case, the vehicle behavior over the first period and the vehicle behavior over the second period are recorded as vehicle behavior information over a series of periods, and the information for identification recorded in association with the first period is recorded. There is provided a recording control system, wherein information for specifying that enables specification of a point in time at which the predetermined condition is newly satisfied is recorded in association with each other.

  In the recording control system according to the first aspect, since a plurality of pieces of identification information are recorded in association with the behavior information of the vehicle over a series of periods, the vehicle information over a series of periods is recorded based on the plurality of pieces of identification information. From the behavior information, it is possible to easily identify the behavior information of the vehicle that the driver needs.

  In the recording control system according to the first aspect, a plurality of pieces of identification information are recorded in association with the behavior information of the vehicle over a series of periods. For example, based on the plurality of pieces of identification information, for example, a large number of “ The vehicle behavior information required by the user can be easily identified and used from the “vehicle behavior information over a series of periods”.

  In addition, for example, it is possible to easily identify and use the behavior information of the vehicle that is necessary by taking into account the relevance at the time when a plurality of predetermined conditions are satisfied in a series of periods. For example, based on the relevance at the time when multiple predetermined conditions were satisfied in a series of periods (for example, if it appeared) Thus, for example, it is possible to easily identify vehicle behavior information required by itself from a large number of series of vehicle behavior information.

  In addition, for example, it is possible to specify vehicle behavior information required by itself based on the number of points in time when a plurality of predetermined conditions are satisfied in a series of periods. For example, the vehicle behavior information at the time point specified by the movement of the vehicle behavior information, the identification information, and the identification information is extracted in order from the vehicle behavior information over a series of periods having a large number of identification information. Etc. can be easily analyzed.

  When the predetermined condition is satisfied, for example, when the value (magnitude) of acceleration (G data) detected by an acceleration sensor mounted on the vehicle becomes a predetermined value or more, a value detected in the vehicle is set in advance. It is good to set it as the time of satisfy | filling any one of some predetermined conditions, such as the time when it corresponds with a value, and the time when predetermined | prescribed switch operation was performed by the user. The time when the predetermined condition is satisfied may be, for example, a time when an event corresponding to an accident occurs. For example, it is good to set it as the time of sudden deceleration corresponding to a collision.

  In addition, when there is an overlap in the recording period between the above-described series of periods and the behavior information of the vehicle over another period that is recorded when another predetermined condition is satisfied, the series of periods and other periods of the vehicle A plurality of pieces of identification information that can identify the behavior information and the time points satisfying the respective predetermined conditions may be recorded.

  For example, information for specifying when the first predetermined condition is satisfied (one that does not overlap with the previous period) and when the second predetermined condition is satisfied (one that overlaps with the previous period) In the example of the configuration to record, the first period recorded when the “previously recorded behavior information of the vehicle over the first period” is satisfied when the first predetermined condition is satisfied (the overlap with the previous period is If the vehicle behavior information for the second period is not recorded, the “vehicle behavior information for the second period recorded when the predetermined condition is newly satisfied” is recorded as the second time. Is equivalent to the vehicle behavior information in the period (the time period overlapped with the first period), and the “vehicle behavior information over a series of periods” continues over the first period and the second period. Control to record as vehicle behavior information for a series of periods

  In addition, in the example of the configuration in which the identification information at the third time is recorded in addition to the identification information at the first time and the second time described above, the “second recording to be performed when a predetermined condition is newly satisfied” is performed. Assuming that the “period of time” is the third time period, “the behavior information of the vehicle over the first period already recorded” corresponds to the behavior information of the vehicle over the first time period and the second time period. “Vehicle behavior information over a period” is controlled to be recorded as vehicle behavior information for a series of periods that continue over the first, second, and third periods.

  Further, in the example of the configuration in which the information for specifying at the fourth time is recorded in addition to the information for specifying at the fourth time as described above, “the vehicle behavior information for the first period already recorded” is recorded. By using the vehicle behavior information for the first to third time periods, the second period to be recorded when a predetermined condition is newly satisfied is set as the fourth time period, and recording control is performed in the same manner as described above. Recorded as vehicle behavior information for a series of periods continuing over the fourth period. The same applies to the fifth and subsequent times.

  The “time point when the predetermined condition is satisfied” and the subsequent “time point when the predetermined condition is newly satisfied” may be, for example, two or more time points that are consecutive within a short time. Specifically, it may be a point in time when the vehicle is continuously impacted, such as a collision immediately after the sudden steering wheel.

  The specifying information is information used to specify a point in time when a predetermined condition is satisfied, and may be time information as in the configuration of the eleventh aspect, for example.

  The vehicle behavior information includes, for example, acceleration information detected by an acceleration sensor mounted on the vehicle, vehicle position information detected from a GPS receiver, speed information detected from a speed sensor mounted on the vehicle, and surroundings of the vehicle. It may be video information taken.

  For example, it is assumed that acceleration information is recorded at intervals of 10 milliseconds (ms) and position information is recorded at intervals of 0.2 seconds (200 ms). The vehicle behavior information is recorded as a series of (vehicle behavior information) data (for example, in one file) for 10 seconds before and 5 seconds after the predetermined condition is satisfied, for example. After that, for example, when the predetermined condition is newly satisfied after 7 seconds from the time when the predetermined condition is satisfied, for example, as in the configuration of the ninth aspect, the continuation is continued from the end of the previous file once closed. Processing is performed so as to record the data of vehicle behavior information. Or, for example, as in the configuration of the tenth aspect, the position of the previous file is specified 2 seconds before the time when the new predetermined condition is satisfied (that is, when the previous file is closed) Processing may be performed so as to record (vehicle behavior information) data of the subsequent portion from the position. Furthermore, after that, for example, when the predetermined condition is newly satisfied within 10 seconds from the time when the previous predetermined condition is satisfied (that is, within the set recording time before the time when the predetermined condition is satisfied), It is good to process so that a part (vehicle behavior information) data may be recorded.

  The vehicle behavior information over the series of periods may be configured to be recordable. That is, the vehicle behavior information over a predetermined period in which there is no overlap may be recorded as vehicle behavior information over another predetermined period (for example, another series of vehicle behavior information). If it does in this way, the behavior information of the vehicle over the series of periods which self requires among the behavior information of the vehicle over a series of a plurality of periods can be specified easily. For example, by focusing on the difference in the length of the period, or by focusing on the relevance of a plurality of identification information included in the behavior information of the vehicle over each series of periods, It is possible to easily find out whether the behavior information corresponds to the behavior information of the vehicle over a series of periods required by itself. It is also possible to compare vehicle behavior information over a series of periods and vehicle behavior information over a series of periods to identify vehicle behavior information over a predetermined period of time required by the user. It becomes. As described above, the vehicle behavior information required by the user can be easily obtained based on a plurality of pieces of identification information from the vehicle behavior information over a series of periods required by the self identified as described above.

It should be noted that the present invention is not construed as being limited thereto, and various changes, modifications, and improvements can be made based on the knowledge of those skilled in the art without departing from the scope of the present invention.

[Example 1]
<Configuration of driving support system>
FIG. 1 is a diagram showing a schematic configuration of a driving support system according to Embodiment 1 of a display control system of the present invention.

  As shown in FIG. 1, the driving support system includes a drive recorder 10 mounted on a vehicle, a memory card 25 that stores an image when a predetermined condition is established in the drive recorder 10, and an image stored in the memory card 25 is reproduced. And a driving support device 30.

  The drive recorder 10 includes a first control unit 11, an acceleration sensor (G sensor) 12, a gyro sensor 13, an atmospheric pressure sensor 14, a GPS antenna 15, and a GPS that measures GPS position information of a vehicle from a GPS signal received by the GPS antenna 15. (Global Positioning System) A first operation unit 17 including a receiver 16, a switch, a button, etc., a first memory 18 for temporarily storing images, a slot for inserting a memory card 25, and a memory card 25 A first IF (interface) 19 for writing an image to the vehicle, a CCD camera 20 installed in the vehicle so as to continuously image the front of the vehicle at a predetermined rate, a vehicle signal acquisition unit 21, and a drive recorder The power supply unit 22 for supplying power to each of the ten elements is included.

  Further, the drive recorder 10 may be configured to be able to reproduce an image on a display of the navigation device in cooperation with a navigation device (not shown). Further, the GPS receiver 16 is not necessarily an essential configuration, but may be configured to acquire position information received by an external device such as an AVM (Automatic Vehicle Monitoring) system or a navigation device.

  The first control unit 11 includes a microcomputer including a CPU, a ROM, a RAM, and the like, and controls the entire operation of the drive recorder 10.

  The G sensor 12 detects gravity acceleration (hereinafter simply referred to as acceleration) in two axial directions (X axis and Y axis) orthogonal to each other, and the detected acceleration (also referred to as G data) together with time data is a first control unit. 11 to send. The first control unit 11 can acquire G data (Gx, Gy) output from the G sensor 12 at intervals of, for example, 10 milliseconds, and determine the acceleration value (magnitude) from the G data.

  Note that Gx represents acceleration in the X-axis direction (front-rear direction of the vehicle), and Gy represents acceleration in the Y-axis direction (left-right direction of the vehicle). Further, the G sensor 12 may use a three-axis sensor including the Z-axis direction (the vertical direction of the vehicle), and the three-axis sensor does not use the acceleration Gz data in the Z-axis direction. Also good.

  The gyro sensor 13 detects the angular acceleration (rotation) of the vehicle, mainly detects the change in the traveling direction of the vehicle (that is, the rotation of the yaw (Z axis) that is the vertical axis), and detects the detected angular acceleration data. Is transmitted to the first control unit 11 together with the time data. The first control unit 11 can acquire angular acceleration data output from the gyro sensor 13 at intervals of, for example, 10 milliseconds, and determine the value (magnitude) of angular acceleration from the angular acceleration data.

  The atmospheric pressure sensor 14 detects atmospheric pressure outside the vehicle, calculates the altitude based on the detected atmospheric pressure value, and transmits the atmospheric pressure value and altitude value (atmospheric pressure / altitude data) to the first control unit 11 together with time data. . For example, the first control unit 11 can acquire the atmospheric pressure / altitude data output from the atmospheric pressure sensor 14 at intervals of 10 milliseconds, and determine the value (size) of the atmospheric pressure / altitude from the atmospheric pressure / altitude data.

  In the first control unit 11, the CCD camera 20 captures one image every 100 milliseconds, and sequentially stores the captured image together with time data in the first memory 18 (to a memory card 25 described later). Control to perform primary storage) For example, the first memory 18 is configured to always store image data for 24 seconds (240 images) captured by the CCD camera 20. The image captured by the CCD camera 20 is not limited to one image every 100 milliseconds, but may be one image every 50 milliseconds, for example. Moreover, you may comprise so that the moving image image | photographed with the CCD camera 20 may be memorize | stored.

  The vehicle signal acquisition unit 21 is connected to a vehicle failure diagnosis connector, acquires various signals and information (vehicle data) of the vehicle at intervals of, for example, 100 milliseconds, and performs first control on the acquired vehicle data together with time data. To the unit 11. Vehicle data includes, for example, [1] a signal that detects a brake operation while driving the vehicle, [2] a signal that also detects a blinker operation, [3] a signal that also detects an accelerator operation, and [4] a steering wheel rotation. The detected signal, [5] the same signal that detected the shift lever position, [6] the same signal that detected the side brake operation, and [7] the vehicle fault diagnosis information (OBD) obtained from the vehicle fault diagnosis system (OBD) in the vehicle ( Vehicle speed, engine speed, cooling water temperature, etc.] [8] Various vehicle information obtained via in-vehicle LAN (CAN) (functional control data from the vehicle's ECU (Electronic Control Unit), network outside the vehicle, etc. Communication data from other vehicles).

  As an example, when the vehicle signal acquisition unit 21 acquires a signal for detecting a brake operation, the brake operation data indicating whether or not the vehicle brake is operated, and the brake operation start time data indicating the time when the brake operation is started. And the brake operation end time data indicating the time when the brake operation is ended is transmitted to the first control unit 11. That is, according to the brake operation data, the brake operation start time data, and the brake operation end time data from the vehicle signal acquisition unit 21, the first control unit 11 determines whether the brake operation is performed, the time when the brake operation is started, and The time when the brake operation is finished can be determined.

  As another example, when the vehicle signal acquisition unit 21 acquires a signal that detects steering wheel rotation, steering wheel rotation data that indicates whether or not the steering wheel of the vehicle has been rotated, and steering wheel rotation start that indicates the time at which steering wheel rotation has started. The time data and the handle rotation end time data indicating the time when the handle rotation is ended are transmitted to the first control unit 11. That is, according to the steering wheel rotation data, the steering wheel rotation start time data, and the steering wheel rotation end time data from the vehicle signal acquisition unit 21, the first control unit 11 determines whether the steering wheel rotation is performed, the steering wheel rotation start time, and The time when the steering wheel rotation is completed can be determined.

  Note that some or all of the GPS antenna 15, the GPS receiver 16, the first IF 19, the CCD camera 20, the vehicle signal acquisition unit 21, and the like may be configured separately from the drive recorder 10. For example, when linked with an existing navigation device having a GPS function, the drive recorder 10 does not require a function such as the GPS receiver 16, so that the cost of the drive recorder 10 can be reduced by that amount.

  The driving support device 30 includes a second control unit 31, a display unit 32 configured by a display, an output unit 33 configured by a printer that prints a display screen on a paper surface, and input devices such as a keyboard and a mouse. A second operation unit 34, a second memory 35 for temporarily storing an image, a slot for inserting the memory card 25, and a second IF (interface) 36 for reading an image from the memory card 25, etc. And an image processing unit 37 for performing predetermined image processing on the input image.

  The second control unit 31 includes a CPU, a ROM, a RAM, and the like, and is a personal computer (PC) on which driving support software is installed. The second control unit 31 interprets and executes a program included in the driving support software and drives the driving support device 30. The various components according to the present invention are realized by operating each of the components.

  The memory card 25 is a rewritable nonvolatile semiconductor memory card having a storage capacity of 2 Gbytes. The memory card 25 is inserted into a slot constituting the first IF 19, and is stored in a predetermined image (for example, a predetermined image) that is always cyclically stored in the first memory 18 for a predetermined period before and after a predetermined condition is satisfied. An image for 10 seconds before the condition is established and an image for 5 seconds after) are stored. Thereafter, the memory card 25 is ejected from the slot constituting the first IF 19 and reinserted into the slot constituting the second IF 36, and the stored image is output to the driving support device 30.

  Although a semiconductor memory card is used as the memory card 25, the present invention is not limited thereto, and a semiconductor memory other than the card type, a portable hard disk (HD), other storage media, and the like can be used. Further, the storage capacity of the memory card or the like is arbitrary and can be freely determined according to the application.

  When a predetermined condition is satisfied (that is, when an event to be recorded by the drive recorder 10 occurs), the drive recorder 10 specifically includes (a) a sudden brake, a sudden handle, a collision, etc. When an impact is applied to the vehicle due to the occurrence of an event corresponding to the occurrence of another accident, and the value (size) of the G data output from the G sensor 12 provided therein exceeds a predetermined threshold Or other (b) When the emergency switch of the first operation unit 17 is pressed, the detection is established for a predetermined condition, and several seconds to several tens of seconds before and after that point (for example, 10 seconds before, 5 seconds after) Various data are acquired together with predetermined condition establishment time data, and recorded in the memory card 25 as one piece of driving information.

  The driving information recorded in the memory card 25 includes G data output from the G sensor 12, angular acceleration data output from the gyro sensor 13, atmospheric pressure / altitude data output from the atmospheric pressure sensor 14, and positioning by the GPS receiver 16. GPS position information, camera image data captured by the CCD camera 20, various signals and information of the vehicle acquired by the vehicle signal acquisition unit 21 (detection data such as brake operation and steering wheel rotation, vehicle speed data, etc.).

  The drive recorder 10 supports a plurality of camera images one by one for several seconds to several tens of seconds before and after a predetermined condition is satisfied when an event to be recorded occurs (for example, 10 seconds before and 5 seconds after). In addition, various data of driving information is recorded in the memory card 25.

<Data structure of memory card>
Next, the data structure of the contents recorded on the memory card 25 will be described with reference to FIG. FIG. 2 is a diagram conceptually showing the data structure of the contents recorded on the memory card 25.

  As shown in FIG. 2, in the memory card 25, corresponding driving information is divided and recorded as driving information 1, driving information 2, and driving information 3 every time each predetermined condition is satisfied. The driving information 1 includes 150 camera images 1 to 150 corresponding to 15 seconds before and after the predetermined condition is satisfied (front 10 seconds and rear 5 seconds), and image related information including other driving information other than the camera images. Consists of The image related information includes G data when a predetermined condition is satisfied, main item data including time data thereof, and related data 1 to 150 corresponding to 150 camera images 1 to 150, respectively. The same applies to the driving information 2 and 3.

  Main item data includes G data, angular acceleration data, barometric pressure / altitude data, and time data. Image-related data includes the date and time of shooting of the camera image, and various signals and information of the vehicle at the time of shooting the camera image. (Detection data such as brake operation and steering wheel rotation, vehicle speed data, etc.) and vehicle GPS position information are included.

<Acceleration change when a predetermined condition is satisfied and image storage method>
Next, referring to FIG. 3 and FIG. 4, a change in acceleration (G data) detected by the G sensor 12 (see FIG. 1) of the drive recorder 10 when a predetermined condition such as an impact on the vehicle is satisfied. And a method of storing images and the like in the drive recorder 10 will be described.

  FIG. 3A shows a time-series change in G data (combined value of Gx and Gy) output from the G sensor 12, and FIGS. 3B and 3C show that each predetermined condition is satisfied. FIG. 3D shows an example of an image period stored as one file in the memory card 25, and FIG. 3E is a source of a thumbnail image to be created. An example of image selection timing is shown. The creation and display of thumbnail images will be described later. FIG. 4 is a flowchart showing the recording process of the drive recorder.

  For example, when the driver performs a sudden steering operation and a rear-end collision occurs immediately thereafter, as shown in FIG. 3 (a), (1) First, the G sensor 12 is applied from the point in time when the impact is applied to the vehicle by the sudden steering operation. The value (magnitude) of the G data output from the vehicle suddenly increases from almost zero. (2) Next, when the rear-end collision occurs, an impact is applied to the vehicle again, and the value (magnitude) of the G data rapidly increases. The case will be described.

  As shown in FIG. 3A, (1) First, at a time tp1 when the value (magnitude) of G data rapidly increases, the value (magnitude) of G data of the G sensor 12 is changed to a threshold acceleration Gs (for example, 0.3G), the first control unit 11 determines (determines) that the predetermined condition has been satisfied (YES in step S11 in FIG. 4), and will be described later from the time when the previous predetermined condition is satisfied. It is determined whether the “predetermined time” has elapsed (step S12 in FIG. 4). It is determined that a predetermined time has elapsed since the previous predetermined condition was satisfied (YSE in step S12), and an image that has been picked up by the CCD camera 20 and is always temporarily stored in the first memory 18 in a cyclic manner is newly added. Data (new data file) is stored in the memory card 25 (step S13 in FIG. 4), and at the same time, the time data (TP1) at time tp1 is stored in the memory card 25 as time data when a predetermined condition is satisfied. Operate.

  Specifically, as shown in FIG. 3B, an image PA1 for TA seconds before time tp1, an image PB1 for TB seconds after time tp1, and time data (TP1) at time tp1 Control is performed so that the data is stored in the memory card 25 as a new data file. For example, TA can be 10 seconds and TB can be 5 seconds.

  It should be noted that the TA and TB periods can be set freely. For example, while displaying the set time (seconds) on the setting screen (not shown) of the drive recorder 10, the time is set by operating the time setting button of the first operation unit 17 of the drive recorder 10, and the set information By saving, you can set any time.

  (2) Next, at the time tp2 when the G data value (magnitude) “seven seconds later” increases from the time tp1 when the predetermined condition is satisfied last time, similarly, the value of the G data of the G sensor 12 When (size) reaches a threshold acceleration Gs (for example, 0.3 G), the first control unit 11 again determines (determines) that the predetermined condition is satisfied (YES in step S11 in FIG. 4). Further, it is determined whether or not “predetermined time” has elapsed since the previous establishment of the predetermined condition (step S12 in FIG. 4). It is determined that the predetermined time has not elapsed since the previous predetermined condition was satisfied (NO in step S12), and the image captured by the CCD camera 20 and always temporarily stored in the first memory 18 is stored in the previous memory. Is stored in the memory card 25 as data continuing to the vehicle behavior data (one data file continuing from the previous data file) (step S14 in FIG. 4), and at the same time, the time data (TP2) at time tp2 is established. It operates so as to be stored in the memory card 25 as time data at the time.

  Specifically, if “predetermined time” has elapsed since the previous establishment of the predetermined condition at time tp2, as shown in FIG. 3C, an image for TA seconds before time tp2 Control is performed such that PA2, the image PB2 for TB seconds after time tp2, and the time data (TP2) at time tp2 are stored in the memory card 25 as new data files. However, in this case (that is, when a predetermined time has not elapsed since the previous establishment of the predetermined condition), as shown in FIG. 3D, an image PA1 [a] for TA seconds before time tp1, The time data TP1 [b] at time tp1 and the image PB1 [c] for TB seconds after time tp1 are stored, and further, the image PA2 for TA seconds before time tp2 following the end of the image PB1. Of these, the partial image PA2a [d] following the last time (te1) of the image PB1 excluding the portion overlapping with the image PB1, the time data TP2 [e] at the time tp2, and the time after the time tp2 The image PB2 [f] for TB seconds is stored, and [a] to [f] are stored as one data file.

  That is, in this case, the one data file includes a series of continuous periods from the start time (time ts1) of TA seconds before time tp1 to the end time (time te2) of TB seconds after time tp2. And the time data TP1 at time tp1 and the time data TP2 at time tp2 are stored.

  As described above, for example, (1) a driver performs a sudden steering operation, and (2) a new collision occurs immediately after the predetermined condition has been satisfied, such as when a rear-end collision is made immediately thereafter. When the predetermined condition is satisfied, the image for TA seconds before the new predetermined condition is established (tp2) following the tail of the image PB1 for TB seconds after the establishment time (tp1) of the previous predetermined condition is satisfied. Of PA2, the subsequent partial image PA2a after the last time point (te1) of the image PB1 is stored.

  The above-mentioned “predetermined time”, that is, the time from when the previous predetermined condition is satisfied [time tp1] to the next predetermined condition is satisfied [time tp2] is TB seconds after time tp1 (for example, 5 seconds). 2 seconds) and TA seconds before time tp2 (for example, 10 seconds) are added (for example, 15 seconds), and overlaps TA seconds after time tp1 and TB seconds before time tp2. If there is. That is, the end time (time te1) of TB seconds after time tp1 is the same as the start time (time ts2) of TA seconds before time tp2, or time te1 is earlier than time ts2. (Time).

  Next, the first control unit 11 determines whether or not an end signal due to an OFF operation of an ACC switch or a power switch (not shown) in the first operation unit 17 has been received (step S15 in FIG. 4). When the end signal is received (YES in step S15 in FIG. 4), the end process is performed (S16), and the series of processes is ended. If the end signal has not been received (NO in step S15 in FIG. 4), steps S12 to S14 in FIG. 4 are repeatedly executed.

  When an event such as an impact is applied to the vehicle as described above and the value (size) of G data detected by the G sensor 12 exceeds a predetermined threshold value, every time a predetermined condition is satisfied (event occurrence) The first control unit 11 includes (a) image data and (b) time data (TP1, TP2) when a predetermined condition is established (time), together with (c) detection G data (Gx, Gy) of the G sensor 12 and The time data, (d) the detected angular acceleration data of the gyro sensor 13 and the time data thereof, (e) the atmospheric pressure / altitude data of the atmospheric pressure sensor 14 and the time data thereof, (f) the time tp1 acquired by the vehicle signal acquisition unit 21 Vehicle data and its time data (for example, brake operation data and its time data, steering wheel rotation data and its time data) for TA seconds before, tp2 and for TB seconds after time tp1, tp2. The vehicle speed data and its time data, etc.), stored in the memory card 25. Note that only a part of the data described above may be stored in the memory card 25.

  The number of events (the number of predetermined conditions established) stored in the memory card 25 can be varied according to the storage capacity of the memory card 25. For example, data for 500 events or more can be stored. preferable. Further, the first control unit 11 stores the data file in the memory card 25 every time the predetermined condition is satisfied, except when the predetermined time is determined to be satisfied a plurality of times within a predetermined time as described above. Created, image data, time data (TP1, TP2,...) When a predetermined condition is satisfied, G data (Gx, Gy) of the G sensor 12 and its time data, angular acceleration data and its time data, barometric pressure / altitude data It is preferable to store the time data, the vehicle data, and the time data.

  Note that when the predetermined condition described above is satisfied, exceeding the threshold acceleration Gs is determined to be satisfied. For example, when the amount of change in acceleration per unit time exceeds a certain value (in 0.1 seconds, It may be determined that the predetermined condition is satisfied when the value (size) of the G data changes by 0.1 G or more.

<Thumbnail image creation and display processing>
Next, thumbnail image creation and display processing in the driving support device 30 will be described with reference to FIG. In this example, a description will be given of thumbnail image creation and display processing operations related to a series of vehicle behaviors when a predetermined condition is satisfied twice within a predetermined time.

  FIG. 5 is a flowchart illustrating thumbnail image creation and display processing according to the first embodiment. This thumbnail image creation and display processing is loaded from the HDD or the like into the RAM of the second control unit 31 of the driving support device 30. This is realized by the CPU executing in accordance with the control program, and is started based on the operation of starting the driving support software of the second operation unit 34. Further, it is assumed that when the processing of the flowchart shown in FIG. 5 is started, the memory card 25 in which the image is stored in the drive recorder 10 is inserted into the second IF 36 constituting the slot.

  In step S <b> 21, the second control unit 31 acquires time data (TP <b> 1, TP <b> 2) at a predetermined condition establishment time (time) from the data stored in the memory card 25.

  In the next step S22, the second control unit 31 takes a plurality of images taken at a plurality of different timings from the images PA1, PB1, PA2a, PB2 in the period before and after the times tp1, tp2 shown in FIG. Select an image.

  Specifically, in this control program, the TA at the time tp1 shown in FIG. 3E is selected from the images PA1, PB1, PA2a, and PB2 in the period before and after the time tp1 and tp2 shown in FIG. The image P1 captured at time ts1 before the second (for example, 10 seconds) is selected as the “first image”, and images P2 to P7 captured at predetermined intervals after time ts1 are sequentially selected as “second to seventh image”. And the image P8 taken at time tp1 is selected as the “eighth image”. Further, the images P9 to P11 taken at a predetermined interval after time tp1 are selected as “9th to 11th images”, and the image P12 taken at time tp2 is selected as “12th image”. Furthermore, images P13 to P15-15 taken at a predetermined interval after time tp2 are selected as “13th to 15th images”, and finally taken at time te2 after TB seconds (for example, 5 seconds) after time te2. Control processing for selecting the image P16 as the “sixteenth image” is programmed. The second control unit 31 performs selection control of the first to sixteenth images from the images PA1, PB1, PA2a, and PB2 according to such a control program.

  “Second to seventh, 9-11, and 13-15 images” other than the first, eighth, twelfth, and sixteenth images (images P1, P8, P12, and P16) taken at times ts1, tp1, tp2, and te2. The image intervals of the images P2 to P7, 9-11, and 13-15 selected as can be set to, for example, about 1.25 to 1.75 seconds, but the optimum value depends on the application. It may be configured to select. For example, the time is set by setting the time by operating the time setting button of the second operation unit 34 of the driving support device 30 while displaying the set time (seconds) on the setting screen (not shown) of the driving support device 30. By saving the information, you can set any time.

  In the next step S23, the second control unit 201 stores the “first to sixteenth images selected in step S22 with respect to the image processing unit 37 according to the control program stored in the ROM in the second control unit 201”. ”(P1 to P16) to perform image processing for creating first to sixteenth thumbnail images.

  In order to create a thumbnail image from the selected first to sixteenth images, for example, the original first to sixteenth images are subjected to image processing for reducing each, and a thumbnail image is created. In addition to the image processing to be reduced, other predetermined image processing such as performing image processing for enlarging the selected first to 16th images or performing image processing for cutting out a part of the image. A thumbnail image may be created by applying. Alternatively, the selected first to sixteenth images may be used as thumbnail images without any image processing.

In subsequent step S24, the second control unit 31 stores the times tp1 and tp2 created in step S23 (that is, a predetermined value) for the image processing unit 37 in accordance with the control program stored in the ROM in the second control unit 31. Image processing for superimposing (superimposing) color lines, characters, marks, and the like on the eighth and twelfth thumbnail images at the time when the condition is satisfied is performed.
For example, in the eighth thumbnail image, a yellow horizontal line is superimposed on the lower part of the image, and a yellow character is superimposed on the upper right part of the image. In the twelfth thumbnail image, a green horizontal line is superimposed on the lower portion of the image, and a green character is superimposed on the upper right portion of the image. As characters to be displayed, color characters such as “impact” and “switch” indicating the type of the predetermined condition are superimposed.

In subsequent step S25, the second control unit 31 stores the first to sixteenth thumbnail images created in step S24 to the display processing unit 38 in accordance with the control program stored in the ROM in the second control unit 31. Display processing to be displayed on the display unit 32 is performed. Specifically, as described later, thumbnail images are arranged in a matrix structure and displayed as a list on the same screen.
This completes the creation and display processing of thumbnail images related to a series of vehicle behaviors when the predetermined condition is satisfied twice within a predetermined time.

<Time chart image creation and display processing>
Next, time chart image creation and display processing in the driving support device 30 will be described with reference to FIG. In this example, a description will be given of a time chart image creation and display processing operation relating to a series of vehicle behaviors when the predetermined condition is satisfied twice within a predetermined time.

  FIG. 6 is a flowchart illustrating the creation and display processing of the time chart image according to the first embodiment. This creation and display processing of the time chart image is performed from the HDD or the like in the RAM of the second control unit 31 of the driving support device 30. This is realized by the CPU executing in accordance with the loaded control program, and is started based on the operation for starting the driving support software of the second operation unit 34. Further, it is assumed that when the processing of the flowchart shown in FIG. 6 is started, the memory card 25 in which the image is stored in the drive recorder 10 is inserted into the second IF 36 constituting the slot.

In step S <b> 31, the second control unit 31 acquires time data (TP <b> 1, TP <b> 2) at a predetermined condition establishment time (time) from the data stored in the memory card 25.
In the next step S32, the second control unit 31 stores dots, vertical lines, and the like on the time axis of the time chart image to the image processing unit 37 in accordance with the control program stored in the ROM in the second control unit 31. Image processing for superimposing characters and the like is performed.

As described above, the driving support device 30 according to the first embodiment has the following advantages. That is,
(1) Since the time data when the predetermined condition is satisfied a plurality of times is recorded in association with the vehicle behavior over a series of times when the predetermined condition is satisfied a plurality of times, the predetermined condition is satisfied a plurality of times. Based on the time data at the time, the behavior of the vehicle when the predetermined condition is satisfied can be easily specified.
For example, the time at which two predetermined conditions are established in association with a vehicle behavior over a series of periods in which a predetermined condition is satisfied twice, such as when a sudden steering operation is performed and the vehicle is impacted immediately afterward and an impact is applied to the vehicle. Easily identify vehicle behavior at each point of time based on the data, and easily identify and use the vehicle behavior information that you need from a number of "vehicle behaviors over a series of periods" be able to.

(2) As in the display mode of thumbnail images and the like illustrated in FIG. 8, the play list unit 42 displays a list of file numbers of driving information files and type characters at all times when predetermined conditions are satisfied. Therefore, it is possible to easily select one driving information file from a plurality of driving information files by confirming the number of times and types of predetermined conditions included in one driving information file.
In addition, since the type of the predetermined condition is displayed in different colors at each time when the predetermined condition is satisfied, it can be determined from the color information that the time is different. Furthermore, for example, by determining the color order in advance such that the color at the first time point is “yellow”, the next color is “green”, and the next color is “blue”. Can also be determined.

(3) Like the display mode of the thumbnail images and the like illustrated in FIG. 8, the thumbnail image portion 43 includes the thumbnail images M8 at the times tp1 and tp2 at which the predetermined condition is satisfied among the 16 thumbnail images M1 to M16. , M12, a yellow or green horizontal line or a predetermined condition type character is displayed, so that the thumbnail images M8, M12 when the predetermined condition is satisfied and the thumbnail images other than when the predetermined condition is satisfied can be distinguished at a glance. I can gaze.
Further, since the horizontal lines and the predetermined condition type characters of different colors are displayed on the thumbnail images M8 and M12 at the time when the different predetermined conditions are satisfied, the two can be distinguished at a glance.

  Further, the color (yellow and green) of the horizontal lines and the predetermined condition type characters displayed on the thumbnail images M8 and M12 are set to the same color (yellow and green) as the color of the predetermined condition type characters displayed on the playlist section 42. Therefore, assuming that the same color display is the one at the time when the same predetermined condition is satisfied, the thumbnail image at the time when the same predetermined condition is satisfied and the predetermined condition type displayed on the playlist section 42 can be distinguished and recognized at a glance. it can.

(4) Like the display mode of thumbnail images and the like illustrated in FIG. 8, the time chart unit 44 includes a yellow or green dot, vertical line, or predetermined condition on the horizontal axis of the time chart when the predetermined condition is satisfied.

  Further, the color (yellow and green) of the dots and vertical lines displayed on the horizontal axis of the time chart and the predetermined condition type characters (yellow and green) are the same as the colors of the predetermined condition type characters displayed on the playlist section 42 (yellow and green). Therefore, assuming that the same color display is the one when the same predetermined condition is met, the dots and vertical lines of the time chart unit 44 when the same predetermined condition is met, and the predetermined condition type characters are displayed on the playlist unit 42. The predetermined condition types can be distinguished and recognized at a glance.

(5) Like the display mode of thumbnail images and the like illustrated in FIG. 8, the position at the time when the predetermined condition is established is displayed on the map 45 as a yellow or green arrow or a predetermined condition type character on the road map. Therefore, it is possible to easily grasp the position when the predetermined condition is established on the road map.
Further, since different colored arrows and predetermined condition type characters are displayed at the positions when different predetermined conditions are established on the road map, the two can be distinguished at a glance.

  Furthermore, the color of the arrow and the predetermined condition type character (yellow and green) displayed on the road map is the same color (yellow and green) as the color of the predetermined condition type character displayed on the playlist section 42. Assuming that the same color display is the one when the same predetermined condition is established, the arrow of the map unit 45 and the predetermined condition type character color when the same predetermined condition is established, and the predetermined condition type displayed on the play list unit 42 at a glance It can be distinguished and visually recognized.

It is determined that the predetermined time has not elapsed since the previous predetermined condition was satisfied (NO in step S12), and the image captured by the CCD camera 20 and always temporarily stored in the first memory 18 is stored in the previous memory. Is stored in the memory card 25 as data continuing to the vehicle behavior data (one data file continuing from the previous data file) (step S14 in FIG. 4), and at the same time, the time data (TP2) at time tp2 is established. It operates so as to be stored in the memory card 25 as time data at the time.

  Specifically, if “predetermined time” has elapsed since the previous establishment of the predetermined condition at time tp3, as shown in FIG. 9D, an image for TA seconds before time tp3. Control is performed so that PA3, the image PB3 for TB seconds after time tp3, and the time data (TP3) at time tp3 are stored in the memory card 25 as new data files. However, in this case (that is, when a predetermined time has not elapsed since the previous predetermined condition was satisfied), as shown in FIG. 9E, an image PA1 [a] for TA seconds before time tp1, The time data TP1 [b] at time tp1 and the image PB1 [c] for TB seconds after time tp1 are stored, and further, the image PA2 for TA seconds before time tp2 following the end of the image PB1. Of these, the partial image PA2a [d] following the last time (te1) of the image PB1 excluding the portion overlapping with the image PB1, the time data TP2 [e] at the time tp2, and the time after the time tp2 The image PB2 [f] for TB seconds is stored, and the image PB2 excluding the portion overlapping with the image PB2 in the image PA3 for TA seconds before the time tp3 following the end of the image PB2. The last time (t 2) The subsequent partial image PA3a [g], time data TP3 [h] at time tp3, and image PB3 [i] for TB seconds after time tp3 are stored, and [a] to [i]. Are stored as one data file.

  That is, in this case, the one data file includes a series of continuous periods from the start time (time ts1) of TA seconds before time tp1 to the end time (time te3) of TB seconds after time tp3. The time data TP1 at time tp1, the time data TP2 at time tp2, and the time data TP3 at time tp3 are stored.

  As described above, for example, (1) a sudden handle operation is performed, (2) a rear-end collision is performed immediately thereafter, and (3) an emergency switch is pressed thereafter, the predetermined condition is satisfied from the time when the predetermined condition is satisfied. If the new predetermined condition is satisfied before the time elapses, and if another new predetermined condition is satisfied before the predetermined time elapses from the time when the new predetermined condition is satisfied, Following the tail of the image PB1 for TB seconds after the establishment time (tp1), among the images PA2 for TA seconds before the establishment time (tp2) of the new predetermined condition, the last time (te1) of the image PB1 ) The subsequent partial image PA2a is stored, and after the end of the image PB2 for TB seconds after the new predetermined condition is established (tp2), another new predetermined condition is established (tp3). Image P for TA seconds before) Of the three, it stores the last time point (te2) after the continuation of the partial image PA3a image PB2.

As described above, the driving support device 30 of the second embodiment has the following advantages. That is,
For example, there are two times when a predetermined condition is satisfied, such as when a sudden steering operation is performed and a rear-end collision is applied to the vehicle, and an impact is applied to the vehicle. Further, the emergency switch is pressed and the predetermined condition is satisfied three times in total. In association with vehicle behavior over a series of periods, the behavior of the vehicle at each time point can be easily identified based on the time data when three predetermined conditions are established, and a number of "vehicle behavior over a series of periods" From the inside, it is possible to easily identify and use the behavior information of the vehicle required by itself.

(1) In the above-described embodiment, it is determined that the predetermined condition is satisfied when the value (size) of the G data output from the G sensor 12 reaches the threshold acceleration Gs (time tp1, tp2). Not limited to this, for example, the predetermined condition is established when the value (magnitude) of the angular acceleration data output from the gyro sensor 13 or the atmospheric pressure / altitude data output from the atmospheric pressure sensor 14 becomes a predetermined value. You may judge. Further, it may be determined that the predetermined condition is satisfied from the result of analyzing the recorded video.
In addition, an event occurs when a signal is input from an external port or when a command is received by communication from an external device such as an AVM-ECU (Automatic Vehicle Monitoring-Engine Control Unit) (for example, RS-232C). Sometimes it is good.

(2) In the above-described embodiment, as G data, component acceleration (G data) Gx in the X-axis direction (vehicle longitudinal direction) and component acceleration (G data) Gy in the Y-axis direction (vehicle left-right direction) Although the composite condition is used to determine whether the predetermined condition is satisfied, the present invention is not limited to this, and each component acceleration (Gx, Gy) may be used individually to determine whether the predetermined condition is satisfied. For example, when Gx exceeds a predetermined threshold and then Gy exceeds a predetermined threshold within a predetermined time, the predetermined condition is satisfied when the change pattern of the value (magnitude) of each component takes a predetermined pattern. You may make it judge that it was materialized. Further, in addition to Gx and Gy, the component acceleration Gz in the Z-axis direction (the vertical direction of the vehicle) may be taken into consideration to determine whether the predetermined condition is satisfied.

(3) In the above-described embodiment, the TA second time and the TB second time before and after the times tp1 and tp2 determined to satisfy the predetermined condition are different from each other (in the example, 10 seconds before and 5 seconds after). In particular, the time of TA seconds before the times tp1 and tp2 is lengthened and the time of TB seconds after the time is shortened, but not limited to this, for example, the time of TA seconds before the times tp1 and tp2 is shortened. The time of the subsequent TB seconds may be long (for example, 5 seconds before and 15 seconds after), and the time of TA seconds and the time of TB seconds may be the same time.

(4) Not limited to the above-described embodiment, the time of TA seconds and the time of TB seconds before and after the times tp1 and tp2 determined to satisfy the predetermined condition, or the total time of TA seconds and TB seconds depends on the type of the predetermined condition. A different time is recommended. For example, the recording period (time) of vehicle behavior information to be recorded when a predetermined condition is satisfied may be increased for a type that requires a long time and shortened for a type that requires a short time.

(5) In the above-described embodiment, the time data when the predetermined condition is satisfied is recorded in the same data file as the vehicle behavior data such as image data and G data. However, the time data when the predetermined condition is satisfied is not limited thereto. Alternatively, the relationship between the time data and the vehicle behavior data may be recorded in a data file different from the recorded data file.

(6) In the above-described embodiment, the time data (TP1, TP2) at that time is stored as information that can specify the time (tp1, tp2) when the predetermined condition is satisfied. You may memorize | store the elapsed time data from the time of a time. The time of the reference time is, for example, the start time of a series of periods (that is, the start time of TA seconds before the first predetermined condition is established in the period recorded as one data file). It may be the elapsed time up to the time when the predetermined condition is satisfied.

(7) Not limited to the above-described embodiment, when vehicle behavior information such as GPS position data is repeatedly acquired at predetermined time intervals, the predetermined condition establishment time point is a time point that matches any of the predetermined time intervals. Good.
For example, when GPS position data is acquired at 1 second intervals, when the predetermined condition is satisfied is a time point 0.6 seconds after the GPS position data is acquired, next, when the GPS position data is acquired The predetermined time is assumed to be satisfied when the predetermined condition is satisfied. In this way, the time when the predetermined condition is satisfied can be made coincident with the time when the GPS position data is acquired, and the time data when the GPS position data is acquired can be acquired as time data when the predetermined condition is satisfied.

(8) In the above-described embodiment, the play list unit 42 is displayed with characters of different colors for each predetermined condition, but the present invention is not limited to this. It is good to display with color fill and background. The same applies to the type characters of the predetermined condition displayed on the thumbnail image portion 43, the time chart portion 44, and the map portion 45.

(9) In the above-described embodiment, the display control system of the present invention has been described as an example of the driving support system (driving support device 30), but can be implemented as a function of various electronic devices. For example, you may incorporate as a function of a navigation apparatus, a drive recorder, a radar detector, and a car audio.
