The image event information number (step S203. See FIG. 3 below). After the driving recorder 200 transmits the event occurrence information, the driving recorder 200 determines whether the image data captured during the period including the event occurrence time is It is recorded in the driving recorder (step sl4). When the image data is recorded in the driving recorder, the driving recorder 200 transmits the image data to the digital speed recorder 100 via the communication line 3 ( Step S105) On the other hand, the digital speed recorder 10 determines whether the image data is received by 098127214 12 201009751 (step S204)' and when the image data is received, the digital speed recorder 10G makes the received image data Coordinate with the image event information number, and record the coordinated image data (step S2〇5, see Figure 3 below) Fig. 3 is a schematic diagram showing a structural example of data recorded in an information recording apparatus for a vehicle used in the first embodiment of the present invention. The digital speed recorder 100 adds an image event information number to a time at which an event occurrence time is displayed. In the Φ data, and as shown in Fig. 3, the time data and the image event information number are recorded in step S203. Further, in step S205, as shown in Fig. 3, the digital speed recorder 1 is added to the time. The image event information number of the same image event information number of the data is added to the image data received from the driving recorder 2 (8) and the image data and the image event information number are recorded. Therefore, the image data generated in the drive recorder 200 can be coordinated with the travel data relating to the speed or total distance generated by the time series in the digital speed recorder. That is, in the digital speed recorder 100, an image event information number is specified to specify a time zone during which the image data is captured (ie, a time period including a time at which an event occurs), and further by referring to the prescribed time zone. The travel data generated by the digital speed recorder 100 during the time zone is extracted such that the image data at the time of the event can be coordinated with the travel data in the time zone in which the image data is captured. As a result, the data generated by both the digital speed recorder and the driving recorder are coordinated with each other and are only recorded at the necessary time before and after the occurrence of events such as 098127214 13 201009751, and can be provided for later use. Analytical data. The storage location of the image event information number is not limited to the position shown in FIG. As shown in Fig. 3, in the description of the first embodiment, the event occurrence time is coordinated with the image data via the image event information number. The process is implemented to conform to the following situation. When multiple events occur simultaneously in the drive recorder 2, different image event information numbers are assigned to the events, respectively, to distinguish and reference (analyze) the events. The present invention is not limited to a structure in which an event occurrence time is coordinated with image information via an image event information number, but a structure in which an event occurrence time is directly coordinated with image data, for example, a data showing an event occurrence time may be employed. Added to the redundant part of the end of the image data (f0〇ter). Returning to the flowchart shown in FIG. 2, when no image data is transmitted from the drive recorder 2 in step sl4, the drive recorder 2 sets the event flag to 0 (step S106), and The image completion information is transmitted to the digital speed recorder 100 (step S107). The case where no image data is mentioned in step si〇6 includes the case where the camera 22 of the driving recorder 200 stops the capturing operation for any reason to make the image data empty, however, it also includes that no image data is transmitted to the digital position. In the case of the speed recorder 1〇〇, for example, the time required to resolve the event has elapsed since the event occurrence time ^ another aspect - the digital speed recorder 1 that receives the image completion information also sets the event flag It is 0 (step S2〇6) to complete a series of recording operations. Driving 098127214 14 201009751 Recorder 200 goes back to step (4) again to repeat the detection of the occurrence of the event. The event flag additionally described in 'Digital Speed Recording and Driving Recorder' is used to identify the presence of image data to be sent to the digital speed recorder or received by the digital speed recorder or The disappearing mark. In the buffer of the recorder (the description thereof is omitted), the image taken by the driving recorder 2GG is recorded at a predetermined time, and the old data is sequentially updated into new data. Therefore, at the time of occurrence of the event, the image data of the predetermined time before the time of interest can be transmitted to the digital speed recorder 1 in the FIF mode. The prescribed time can be set in advance, or the capacity of the buffer can be appropriately designed to determine the time. Moreover, after the time of the acquisition (sending) event, the time at which the image data is generated is set by the county so that the image data can be recorded for a prescribed time before and after the event occurrence time. ❿ As described above, by taking the occurrence of the event as a trigger, the driving data and the image data obtained at a predetermined time before and after the event occurrence time are coordinated with each other and recorded by the occurrence of the event as a trigger. • Digital speed recorder side. Therefore, reference to the travel data and image data recorded on the CF+160 makes it easier to analyze the events that occur. Figure 4 is a block diagram of an information recording apparatus for a vehicle in a second embodiment of the present invention. The information recording apparatus of the second-inspected vehicle is different from the information recording apparatus in the embodiment of 098, 127, 214, 15, 2010, 097, 051, in that the CF card 260 is used as a recording unit for recording the travel data and video data together. It is not added to the digital speed recorder 100 side, but is added to the side of the drive recorder 2. Since other structures are the same as those in the first embodiment, detailed description thereof will be omitted. Now, the information recording operation for the information recording apparatus of the vehicle having such a structure will be described below.

In the present embodiment, since the CF card as the storage medium is disposed on the drive recorder side, data such as the speed and the travel distance obtained from the digital speed recorder are transmitted to the driving recorder via the communication I/F, and are recorded in On the CF card. Now, the recording operation of the image due to the event detected in the drive recorder side will be described below. Initially, the driving recorder 2 determines whether or not the acceleration sensor 230 as the event detecting unit detects an event (step). Here, the 13 event is a change in acceleration caused by, for example, an impact force applied to the vehicle due to an accident. Therefore, not only accidents, but also sudden braking operations are detected as events. When the field detects an event in step S301, the driving recorder class sets the event flag recorded in the SDRAM 250 to ^ (step illusion 2), and will notify the digital speed record of the event occurrence time of the event occurrence. The event occurrence of the device is sent to the digital speed recorder just now (step magic (6). 098127214 16 201009751 On the other hand, the digital speed recorder 1〇〇 always determines the reception of the event occurrence information (step S401). When the digital speed recorder 1〇 When receiving the event occurrence information from the drive recorder 200, the digital speed recorder 1 sets the event flag recorded in the SDRAM (not shown in FIG. 4) to "Γ" (step S402). The digital speed recorder 1 determines whether or not the travel data regarding the traveling state is to be transmitted to the drive recorder 2 (step S4〇3). When the travel data is available, the digital speed recorder 1 The data is transmitted φ to the driving recorder 2 (step S4〇4). In step S303, after the driving recorder 2 transmits the event occurrence information, the driving recorder 200 keeps displaying the The driving recorder 2 transmits the event occurrence information to the time of the digital speed recorder 1 as the data 'and the image event information number unique to each event occurrence information is coordinated with the event occurrence time. And recording the image event information number and the event occurrence time (step S3G4> the driving recorder fan further determines whether to receive the driving data regarding the driving state (step S3〇5). When receiving the driving data, the driving recorder 200 makes the receiving The driving data is coordinated with the image event information number and records the driving data and the image event information number (step S306, see FIG. 6 below). FIG. 6 is a display data record used in the second embodiment of the present invention. A schematic diagram of a structural example in the information recording device of the vehicle. The driving recorder 2 adds the image event capital number to the time when the display event occurs, and records the time data and shadow in the step== 127127214 17 201009751 code , as shown in Figure 6. In addition, in step % 〇 6, as shown in Figure 6, the driving recorder 200 will be The image event information number of the same image event information number added to the time data is added to the travel data received from the digital speed recorder ι〇〇' and the travel data and image event information number are recorded. Therefore, in the digital speed recorder The driving data generated in the vehicle can be coordinated with the image data generated in the time series in the driving recorder 200. That is, in the driving recorder 2, an image event information number is specified to be specified in Wherein the time zone of the driving data is generated (ie, the time period including the time when the event occurs) and the image data generated by the driving recorder 20 during the time zone is further extracted by referring to the prescribed time zone. The image data at the time of occurrence can be coordinated with the driving data in the time zone in which the image data is captured. As a result, the data generated by both the digital speed recorder and the driving recorder are coordinated with each other, and recorded by both the digital speed recorder and the driving recorder only when necessary time before and after an event such as an accident occurs. The resulting data makes it possible to provide information that can be used for later analysis. The storage ❿ position of the image event information number is not limited to the position shown in FIG. 6. In step S403, when no data is transmitted from the digital speed recorder 1〇〇, the digital speed recorder 1 sets the event flag to 〇 (step S405), and transmits the completion information to the driving recorder 200. To complete a series of recording operations (step S406). On the other hand, the driving recorder 200 that has received the completion information also sets the event flag to 〇 (step s3〇7), and 098127214 18 201009751 and returns to step S301 again to repeatedly detect the occurrence of the event. As described above, the driving data and the image data obtained at the predetermined time before and after the event occurrence time are recorded on the drive recorder 2 side by triggering the occurrence of the event. Therefore, the driving data and image data recorded on the 〇1? card are referred to to enable analysis of the occurrence of the event. As described in detail above, according to the image recording apparatus for a vehicle of the present invention, since the traveling data and the image data are coordinated with each other and are recorded only at the time required for the analysis, it is possible to analyze the vehicle in a highly accurate manner such as an accident. The state of the incident at the time of the accident, without increasing the amount of cost information generated by the recording unit. The present invention has been described and illustrated by the preferred embodiments thereof, and it is obvious to those skilled in the art that various changes and modifications can be made in accordance with the present invention. It is apparent that the above-described changes and modifications are intended to be within the spirit, scope and purpose of the invention as defined by the appended claims.
