FIG. 1 is a block diagram showing an example of a drive recorder system according to an embodiment of the present invention. The drive recorder system of the present embodiment is centered on a vehicle 2 that is either a gasoline engine vehicle or an electric vehicle equipped with a drive recorder that records information before and after an accident, or a so-called hybrid vehicle that uses a gasoline engine and a motor together. However, a system that further cooperates with the traffic light 4 and the fueling / feeding stand 6 is configured.

The vehicle 2 includes a vehicle control unit 8 including a computer that controls the entire vehicle, and controls the vehicle function unit 12 in accordance with an operation of the operation unit 10 by a driver of the vehicle. The function of the vehicle control unit 8 is executed by software stored in the storage unit 14. The storage unit 14 also temporarily stores various data necessary for overall vehicle control. In addition, the vehicle control unit 8 controls the display unit 16 to perform GUI display necessary for operation of the operation unit 10 and display a control result. The vehicle control unit 8 includes a clock unit 18, and time data of the clock unit 8 is used for various functions. Further, as will be described later, the time of the clock unit 18 is automatically corrected to the correct time as appropriate by external time information.

The GPS unit 20 obtains information on the latitude, longitude, and altitude, which are absolute position information of the vehicle 2, from the satellite and the nearest broadcasting station based on the GPS system, and sends the information to the vehicle control unit 8. The car navigation function unit 22 processes absolute position information from the GPS unit 20 obtained via the vehicle control unit 8 and displays the position of the vehicle 2 on the map on the display unit 16. The vehicle 2 further includes a vehicle short-range communication unit 24. As described later, when the vehicle 2 approaches the traffic light 4 and the fueling / power supply stand 6, information is transmitted / received between them by radio waves or light.

Next, a configuration related to the drive recorder will be described in association with the above configuration as necessary. The camera 26 and the microphone 28 are always input with an image and sound of the front of the vehicle when the vehicle is in operation. The operation state includes not only the case where the vehicle actually travels but also all the states where a traffic accident may occur as the vehicle travels, such as a state where the vehicle is temporarily stopped while waiting for a signal. In order to check whether this is the case, the image taken by the camera is detected by the image processing for the presence or absence of moving objects, and even after the engine is stopped, the state in which no moving objects are detected continues for a predetermined time. Unless it is confirmed, image and sound input to the camera 26 and the microphone 28 is continued.

The vehicle control unit 8 includes a non-volatile buffer memory of about 20 seconds, and stores image and sound information input from the camera 26 and the microphone 28 by first-in first-out (FIFO). That is, the latest 20-second information is always overwritten and stored. Then, when the acceleration detection unit 30 detects a large acceleration change due to a collision or the like, or when there is a manual operation by the operation unit 10, if the camera 26 and the microphone 28 continue to input information without being destroyed, at that time Then, the data is continuously stored in the buffer memory for about 10 seconds. As a result, the buffer memory holds image and sound information of about 10 seconds before and after the time of detection of acceleration change or manual operation. The image and sound information of about 10 seconds before and after this is subjected to predetermined processing by the vehicle control unit 8 and then the first recording unit 32 and the second recording unit 34 provided in different parts of the vehicle as digital compressed moving image information. Are configured to be recorded respectively. Each of the first recording unit 32 and the second recording unit 34 has a capacity for 10 pieces of digital compressed moving image information, and is overwritten by the FIFO.

The first recording unit 32 is provided, for example, at the front part of the vehicle, and the second recording unit 34 is provided, for example, at the rear part of the vehicle. I hope that the other will survive and be able to record. It is also expected that recorded information will remain in at least one of them. Even if most of the drive recorder function is destroyed, if the non-volatile buffer memory is safe, a recording of about 20 seconds before the accident is left.

Here, processing performed by the vehicle control unit 8 when recording image and sound information in the first recording unit 32 and the second recording unit 34, respectively, will be described. In addition to the usual process of creating digital compressed video information with audio, this process prevents tampering and replacement of this digital compressed video information with audio to increase evidence and to enrich information as evidence. Processing.

The traffic light 4 is a configuration for enriching evidence information, and the traffic light control unit 36 controls red, blue and yellow signal lights 38. And the traffic light short distance communication part 40 is transmitting the information which signal light of which direction is which color now to the traffic light 4 vicinity. The traffic signal short-range communication unit 40 also has a configuration for transmitting traffic jam information and the like from the vehicle information communication system obtained from the traffic signal system communication unit 42 to the vicinity of the traffic signal 4. Therefore, these pieces of information are received by the vehicle short-range communication unit 24 and sent to the vehicle control unit 8 if the vehicle 2 exists in the vicinity of an intersection where the traffic signal 4 is present. As a result, when a change in acceleration or a manual operation is detected while the vehicle 2 is passing an intersection or stopping at a signal, the state of the signal lamp 38 in the traveling direction of the vehicle 2 can be acquired as information. In this manner, even when the state of the signal lamp 38 cannot be obtained from the image of the camera 26 due to the limit of the angle of view of the camera 26 or the synchronization between the camera 26 and the signal lamp 38, the change in acceleration or the manual operation is detected. It becomes possible to grasp the situation of the signal lamp 38 up to (hereinafter referred to as “occurrence of accident” as a typical case). The direction detection unit 44 detects the direction in which the vehicle is facing immediately before the occurrence of the accident, and provides evidence as to whether or not the signal is ignored in the vehicle 2 when the accident occurs in combination with the information from the traffic light 4 described above. Is.

The vehicle control unit 8 receives the speed information from the speedometer 46, and sequentially overwrites and records the information on the capacity of about 20 seconds in the nonvolatile buffer memory by using the FIFO. This makes it possible to grasp the relationship between the speed at the time of the accident and the speed limit, the brake operation history for about 20 seconds before the accident, and the like. The speed information and the brake operation history when such an accident occurs are digitally watermarked together with the signal light information of the traveling direction when the accident occurs, the accident time information from the clock 18, and the accident point information from the GPS unit 20. The data is sent to the unit 48 and treated as digital watermark data.

The digital watermark processing unit 48 receives image and sound information of about 10 seconds before and after the occurrence of the accident temporarily stored in the buffer memory, and includes the speed information, brake operation history, signal light information, time information, and point information. Digital watermark data is embedded. At the time of embedding, digital watermark processing key information held in the storage unit 14 is set and used. The image and sound information in which the digital watermark data is embedded using the digital watermark processing key information in this way is returned to the vehicle measurement unit 8 and digitally compressed, and the first recording unit 32 and the second recording unit 34, respectively. Sent to. As described above, since the digital watermark information related to the occurrence of the accident is embedded in the image and sound information about 10 seconds before and after the occurrence of the accident using the digital watermark processing key information, the image information and the sound information are falsified. It becomes difficult. Also, by extracting these digital watermark information itself, the evidence information at the time of the occurrence of the accident becomes rich.

As described above, the drive recorder function is described as being controlled by the vehicle control unit 8, but instead of having the vehicle control unit 8 bear all functions, a dedicated control unit in charge of the drive recorder function is provided separately. The function may be shared. Also in this case, the drive recorder dedicated control unit cooperates with the vehicle control unit 8 and executes the functions as described above as a whole.

In addition, in order to prevent information from being recorded on the drive recorder in the event of an accident and to improve the reliability of recording, the components that achieve the drive recorder function described above are It is stored in an inaccessible part and can only be accessed by qualified personnel during vehicle inspections. Further, a cable connecting the camera 26 or the microphone 28 and the vehicle control unit 8 is also stored in a portion that cannot be seen by the owner of the vehicle 2. Even when the drive recorder function is added to the vehicle 2 later, the attachment is limited to qualified persons, and the cable and the like are installed so that the owner of the vehicle 2 cannot be removed without permission. Further, when the drive recorder function is impaired due to accidental disconnection of these cables or the like, the outside display unit 50 displays this outside the vehicle 2, and when this indication is found by the police, it is a traffic violation. Become.

On the other hand, every time the vehicle 2 is started, an initial check of the drive recorder function is performed, and a display indicating that the drive recorder function is normal is displayed on the display unit 16. Instead, it may be notified that the check result is normal by announcement, or both may be used together. Traffic accidents shouldn't happen in nature, and for safe drivers, it's likely that nothing will actually happen for years. During this time, the drive recorder will never have an opportunity to work, but by configuring as described above, it can be confirmed that the function is normal on a daily basis, and information is not recorded in the unlikely event Can be prevented.

The refueling / power supply stand 6 includes a stand short-range communication unit 52 for communicating with a vehicle that has stopped at the stand for refueling or power supply. The stand control unit 54 acquires the ID information of the vehicle 2 and the latest digital watermark processing key information to be applied to the vehicle 2 from the stand system communication unit 56. This latest digital watermark processing key information is transmitted to the vehicle 2 by communication between the stand short-range communication unit 52 and the vehicle short-range communication unit 24, and is sent to the storage unit 14 via the vehicle control unit 8 to be old digital watermark processing key information. Update. Such update of digital watermark processing key information is intended to prevent tampering and replacement of image and sound information by the drive recorder, and the update history of digital watermark processing key information for each vehicle is individually stored in the drive recorder management center. Therefore, even if the digital watermark processing key information is leaked, the digital image information created with the expired digital watermark processing key is not recognized as a genuine record. The digital watermark processing key information may be updated frequently from the traffic light 4.

The oil supply / power supply unit 58 supplies oil / power supply to the oil supply / power supply unit of the vehicle 2 via the oil supply / power supply unit line 60 to the oil supply / power supply unit port. At this time, if the vehicle 2 is an electric vehicle or a hybrid vehicle, the digital watermark processing key information can be transmitted from the stand control unit 54 to the vehicle control unit 8 by power line communication via the oil supply / power supply unit line 60. it can.

As described above, the drive recorder information in the embodiment of the present invention cannot be changed by the owner of the vehicle 2 itself, but the card slot of the vehicle control unit 8 can be entered by the owner entering the password. It is free to copy and take out the memory card inserted in the card. Therefore, it is possible to view the data extracted in this way on its own mobile phone or personal computer.

FIG. 1 illustrates the case where the vehicle 2 updates the digital watermark processing key information by short-range communication with the fueling / power supply station 6. This is not the only case. For example, if “refueling / power supply station 6” is read as “automatic road toll collection system (ETC) 6” and “stand” in its internal structures 52, 54 and 56 is read as “ETC”, it passes ETC 6. It can be understood that the present invention can be implemented by updating the digital watermark processing key information every time. In this case, the vehicle short-range communication unit 24 in the vehicle 2 and the ETC short-range communication unit 52 in the ETC 6 are also used for communication of digital watermark processing key information.

In addition, when it is configured to perform near field communication based on the contractual relationship with the vehicle 2 as in ETC6 and also uses a near field communication unit of a system in which personal information management is firmly performed, It is also possible to perform information communication like this. That is, when any drive recorder information is recorded in the first recording unit 32 or the second recording unit 34, this is automatically automatically transmitted from the vehicle short-range communication unit 24 to the ETC short-range communication unit 52. It can be configured to be transferred from the ETC communication unit 56 to the management center of the ETC. However, whether or not to perform such transfer automatically is subject to obtaining the driver's consent in advance, and if agreed, an incentive such as discounting the expressway fee is attached. As a result, evidence of escaping or hitting and escaping is accumulated in the ETC management center with the driver's consent, so that the driver's awareness of safe driving can be enhanced.

FIG. 2 is a basic flowchart showing functions of the vehicle control unit 8 of the vehicle 2. This flow starts when the vehicle 2 is ready to run. Specifically, in the case of a gasoline engine vehicle, the vehicle is ready for traveling when the ignition is turned on, and in the hybrid vehicle or electric vehicle, the traveling preparation switch is turned on, and the flow starts. Note that the travelable state includes a state where the vehicle is actually traveling. If it is a flow gaster, first, vehicle functions including a drive recorder function are initially checked in step S2. This process includes notification by displaying or announcing the check result.

Next, in step S4, an image and sound are recorded based on information from the camera 26 and the microphone 28. In step S6, the GPS data from the GPS unit 20 at that time, the speed data from the speedometer 46, the traveling direction data from the azimuth detecting unit 44, and the time data from the clock 18 are acquired, and the process proceeds to step S8. .

In step S8, it is checked whether or not the signal light data from the traffic light 4 has arrived at the vehicle short-range communication unit 24. If the vehicle is approaching an intersection and signal light data is received, the process proceeds to step S10, where the data is acquired and the process proceeds to step S12. The traffic light 4 transmits information on the state of the signal lamp 38 in both the traveling direction for the vehicle 2 and the direction orthogonal thereto, and in step S10, the vehicle short-range communication unit 24 All the information is obtained as it is. On the other hand, if the vehicle is not approaching the intersection or is approaching the intersection but the traffic light does not have a signal light data transmission function and as a result there is no incoming data such as a signal, the process proceeds directly from step S8 to step S12. To do.

In step S12, the information obtained in steps S4, S6, and S10 is overwritten and recorded by FIFO in the capacity of about 20 seconds in the nonvolatile buffer memory in the vehicle control unit 8. When the recording of the information obtained at that time is finished in step S12, the process proceeds to step S14, and a check is made as to whether or not the communication partner exists in the communicable distance range and the near field communication is possible. . The communication partner in this case is, for example, the fueling / feeding station 6 or the ETC 6, but the communication device 4 corresponds to the communication partner in this case as long as communication other than signal light information reception is possible.

When it is determined in step S14 that near field communication is possible, the process proceeds to step S16, communication processing by near field communication is performed, and the process proceeds to step S18. In this case, the content of the communication process in step S16 by the vehicle short-range communication unit 24 is specifically the reception of the update information of the digital watermark processing key information. In addition, as described above, the first recording unit The transmission of the drive recorder information recorded in 32 or the second recording unit 34 also corresponds to the communication process in step S16. If it is not detected in step S14 that near field communication is possible, the process directly proceeds to step S18.

In step S <b> 18, it is checked whether or not an acceleration change of a predetermined value or more is detected by the acceleration detection unit 30. Here, the acceleration change of a predetermined value or more includes a change in acceleration during traveling of the vehicle such as a sudden deceleration in the same direction as in a frontal collision and a change in the traveling direction due to the collision, but the vehicle 2 itself was stopped. However, it also includes an impact in the event of a collision with another vehicle.

When a change in acceleration of a predetermined value or more is detected in step S18, the process proceeds to step S20, and the latest digital watermark processing key is read from the storage unit 14 as the vehicle 2. In step S22, digital watermark processing for embedding various digital watermark data in the image / sound information of the moving image based on the digital watermark processing key is performed. Details of this processing will be described later. In step S24, the image / sound information in which the digital watermark is embedded is compressed and recorded in the first recording unit 32 and the second recording unit 34, and the process proceeds to step 26. In addition, when the acceleration change more than predetermined is not detected by step S18, it transfers to step S26 directly.

In step S26, it is checked whether or not the vehicle 2 is in a travelable state, and if applicable, the process returns to step S4. On the other hand, when the vehicle is not ready for traveling due to the ignition being turned off or the traveling preparation switch is turned off, the process proceeds to step S28, and whether or not a moving object is included in the image is detected based on the image acquired by the camera 26. . And if a moving body is detected, it will return to step S4. When a moving object is detected, it means that the vehicle 2 is running due to inertia or hill descent, or the vehicle 2 itself is stopped but the vehicle is running around while its power is off. This means that the vehicle 2 is on the road and the vehicle 2 is not yet in a safe state.

On the other hand, if no moving object is detected in step 28, the process proceeds to step 30, and it is checked whether the detected city state continues for a predetermined time or more. If the predetermined time has not yet been reached, the process returns to step 4. This is because a moving object may not be detected for a predetermined time when the vehicle is immediately after an accident or when the vehicle 2 is stopped on the road but the vehicle does not travel around. As described above, when the process returns from any of step 26 to step 4 to step 4, the processing from the image / sound recording in step 4 is performed. Steps S4 to S30 are repeated until it is considered that the vehicle 2 is stopped at a safe place, and the acquisition of the image / sound data and the predetermined data and the FIFO recording are continued. Each time detection is performed, compressed data of image / sound information in which a digital watermark is embedded is recorded. On the other hand, if it is detected in step S30 that the moving object has not been detected for a predetermined time or longer, the process proceeds to step S32, where the moving image / sound recording and various data acquisition are stopped, and the flow ends.

FIG. 3 is a flowchart showing details of the digital watermark processing in step S22 of FIG. When the flow starts, the ID data of the vehicle 2 is read from the storage unit 14 in step S42. As will be described later, this ID is used as digital watermark data and also as data for specifying the version of the digital watermark processing key currently applied to the vehicle 2. In other words, which version of the digital watermark processing key is currently applied to the vehicle 2 is individually registered in the drive recorder management center. Therefore, by adding the ID of the read vehicle 2, the registered authentic electronic It can be proved that the compressed data is image / sound information in which a digital watermark is embedded by a watermark processing key.

Next, in step S44, in step 3 of FIG. 2, the digital watermark processing key read in step S20 of FIG. Next, in step S46, it is checked whether the buffer memory remains safely without being destroyed after the acceleration change is detected. If it is safe, the process proceeds to step S48, and the GPS data and time data at the time of acceleration change detection are extracted from the buffer memory. Furthermore, in step S50, the traveling direction data at the time of acceleration change detection is extracted from the buffer memory, and the process proceeds to step S52.

In step S52, it is checked whether signal lamp data exists in the buffer memory. The presence of signal light data means that the vehicle 2 was in the vicinity of the intersection in the vicinity of the acceleration change detection time point, so that the process proceeds to step S54, and the signal light data until the acceleration change detection time is extracted. In step S56, the traveling direction signal light data until the acceleration change is detected is determined by referring to the traveling direction data extracted in step S50, and the process proceeds to step S58. On the other hand, when it is determined in step S52 that no signal lamp data exists in the buffer memory, the process directly proceeds to step S58.

In step S58, the entire speed data history in the buffer memory up to the time of acceleration change detection is taken out. In step S60, the state of the brake operation is analyzed based on these, and the process proceeds to step S62. As described above, the data of 20 seconds before the acceleration detection time can be used as the buffer memory data extracted at the time of step S56 and step S58. On the other hand, for image and sound data, as long as the functions of the camera 26 and the microphone 28 are safe, the FIFO recording is continued even after the acceleration change is detected. Overwritten with 10 seconds of data and disappears.

In step S62, it is checked whether or not the functions of the camera 26 and the microphone 28 remain safely after the acceleration change is detected. If either one is safe, the process proceeds to step S64. If any one of the functions of the camera 26 and the microphone 28 is safe, the information is continuously sent from at least one of them after the acceleration change is detected, so that the FIFO recording to the buffer memory is continued. Therefore, in step S64, it is checked whether or not the recording and recording for a predetermined time (about 10 seconds) set after the acceleration change is detected, and the end is awaited. When the predetermined time has elapsed and recording and recording are completed, the process proceeds to step S66. On the other hand, when it is detected in step S62 that both the functions of the camera 26 and the microphone 28 are destroyed and the information after the acceleration change detection can no longer be sent, the process immediately proceeds to step S66. In this case, for the image and sound data, the information in the buffer memory is data for 20 seconds before the acceleration change is detected.

In step S66, the data obtained in steps S42, S48, S56, and S60 are converted into digital watermark data to be embedded. In step S68, all image information and sound information in the buffer memory are extracted, and the process proceeds to step S70. In step S70, on the basis of the information obtained in steps S66 and S68, the process of embedding the digital watermark data into the image and sound information is performed according to the setting in step S44. If it is detected in step S46 that the buffer memory is destroyed, the flow is immediately terminated.

It is a block diagram which shows the Example of the drive recorder system which concerns on this invention. It is a basic flowchart which shows the function of the vehicle control part of FIG. It is a flowchart which shows the detail of step S22 of FIG.
