Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle harming action detection device, and more particularly to a harming action detection device that records a harming action on a vehicle and identifies a person who performs the harming action.

  When a vehicle is parked, a third party may cause damage to the vehicle, such as mischief, hitting and running, and various forms of theft, and various techniques for preventing them have been proposed. For example, there is a technique for detecting a thief entering a vehicle and issuing an alarm (see, for example, Patent Document 1). Such a technique suppresses the subsequent operation of the thief by detecting vibration generated in the vehicle when entering the vehicle and issuing an alarm.

  A technique for preventing theft of a vehicle by using an immobilizer has also been proposed. The immobilizer does not allow the engine to be started unless the transponder ID code embedded in the key matches the vehicle body ID code. An alarm can also be issued when the ID codes do not match.

In addition, in order to prevent theft that the vehicle itself is carried away by a tow truck or the like, a technique for detecting the theft of the vehicle by detecting the inclination or shaking of the vehicle has been proposed (for example, see Patent Document 2). With such a technique, an attempt is made to reliably detect the theft by distinguishing an external force that is not related to the theft, such as vibration or wind traveling on the road surface, and an external force due to the theft.
JP-A-6-305397 JP-A-5-139249

  However, the alarm generating device and the immobilizer described in Patent Literature 1 and the detection of theft behavior described in Patent Literature 2 can suppress theft behavior of the vehicle itself, but prevent valuable goods in the vehicle from being stolen. Can not. Further, there is a possibility that the vehicle is damaged or the vehicle is damaged when the vehicle is invaded.

  Further, these technologies suppress the theft of the vehicle itself, and the perpetrator cannot be identified even if the theft is detected or the start of the vehicle is not permitted. For example, in the case of mischief such as graffiti or hitting away, since the perpetrator (vehicle) has already escaped, the perpetrator cannot be identified even if an alarm is issued, and effective means to prevent such acts Not.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a vehicle action detection apparatus capable of identifying a perpetrator who causes various damages to a vehicle.

  In order to solve the above-described problem, the present invention includes an impact detection unit that detects an impact on a vehicle, and an imaging unit that performs imaging and recording in the vehicle exterior direction for a predetermined time when an impact is detected by the impact detection unit. There is provided an aggression detecting device characterized by the above.

  According to the present invention, when an impact is detected, it is possible to take an image in the direction outside the vehicle, so that it is possible to identify a perpetrator who causes various damages to the vehicle.

  In addition, the present invention includes an imaging unit that continuously performs imaging and recording in the direction of the outside of the vehicle, and an impact detection unit that detects an impact on the vehicle. When the impact is detected by the impact detection unit, the imaging unit There is provided an aggression detection device characterized in that recording is ended.

  According to the present invention, since photographing and recording are performed in advance, it is possible to photograph a perpetuating vehicle that has given an impact to the vehicle, and it is possible to identify a perpetrator who causes various damages to the vehicle. “Continuously” refers to shooting and recording regardless of whether or not there is an impact. When there are a plurality of shooting means (cameras), all of them may not be shooting and recording, or a predetermined number. Shooting and recording may be performed at time intervals of.

  In one embodiment of the present invention, an image processing means for extracting a vehicle number of an injurious vehicle that has given an impact to the vehicle from image data recorded by the photographing means, and when the impact is detected by the impact detecting means, the image processing means And a harm content recording means for recording at least one of the vehicle number extracted by the above, the time when the impact was detected, or the parking position of the vehicle.

  According to the present invention, the harming vehicle can be specified by the number of the harming vehicle, the detection time of the impact, and the place where the hit and escape occurred.

  In one embodiment of the present invention, at least one of the vehicle number extracted by the image processing unit, the image of the injurious vehicle imaged by the imaging unit, or the time when the impact was detected or the parking position of the vehicle, A harm information transmitting means for transmitting to a vehicle user or a security center.

  According to the present invention, the user or the security center can recognize that there has been a hit and escape, and can identify the offending vehicle by the vehicle number or the like.

  In one embodiment of the present invention, the impact detection means includes vibration detection means for detecting the vibration of the vehicle, and vibration integration means for integrating the magnitude of the vibration detected by the vibration detection means. When the integrated value of vibrations integrated by the means exceeds a predetermined threshold, an impact on the vehicle is detected.

  According to the present invention, a small stimulus such as a graffiti is detected as a vibration, and the magnitude of the vibration is integrated, whereby a mischief to the vehicle such as a graffiti can be detected.

  In one embodiment of the present invention, at least one of an image of a person who made an impact on the vehicle recorded by the photographing unit, a time when the impact was detected, or a parking position of the vehicle is sent to the vehicle user or the security center. It is characterized by having harm information transmitting means for transmitting.

  According to the present invention, the user or the security center can recognize that there was a graffiti, and can identify a person who has graffiti based on the captured image.

  It is possible to provide a vehicle-damaging action detection apparatus for a vehicle that can identify a perpetrator who causes various damages to the vehicle.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the accompanying drawings.

  In the present embodiment, a harmful action detection device that identifies a harmful vehicle when the host vehicle is hit and escapes will be described. FIG. 1 is a diagram illustrating a situation in which the host vehicle 1 is evacuated by an offending vehicle 10. In FIG. 1, the host vehicle 1 is parked on the road shoulder, and the perpetrating vehicle 10 contacts the right rear of the host vehicle 1 and escapes as it is (hereinafter referred to as hitting and escaping). The host vehicle 1 photographs the victim vehicle 10 that has been hit and escaped, and transmits information such as image data of the victim vehicle 10, vehicle number, and the time when the hit and escape occurred to the user of the host vehicle 1 and the security center 2. The user or the security center 2 can identify the harming vehicle 10 based on the vehicle number, and in addition to the location where the host vehicle was parked, the escape direction of the harming vehicle 10, etc. 10 can be secured.

  FIG. 2 shows a functional block diagram of the harmful action detecting device. The imaging means 11 captures an image in the vehicle outward direction. The photographing means 11 is composed of a solid-state imaging device such as a CCD or CMOS, but since the generator is also stopped during parking, it is preferable to use a CMOS or the like with low power consumption.

  Preferably, a plurality of photographing means 11 are arranged so as to cover the horizontal plane 360 degrees (omnidirectional) with respect to the host vehicle. The photographing means 11 is installed by adjusting the photographing direction so that the number plate of the harming vehicle 10 and the driver are within the photographing range.

  FIG. 3 shows a plan view of the host vehicle 1 in which the photographing means 11 is arranged. In FIG. 3, cameras 21 a and 21 b that capture images in front of the vehicle are arranged in the dashboard of the host vehicle 1. Cameras 21a and 21b that photograph the front of the vehicle may also be used as cameras provided in a rearview mirror or the like for detecting white lines or obstacles. In addition, cameras 21c and 21d for capturing images on the side of the vehicle are disposed in the vicinity of the B pillar, and cameras 21e and 21f for capturing images on the rear of the vehicle are disposed on the rear board. The harming action detection device captures omnidirectional images from the host vehicle 1 using the cameras 21a to 21f. Since the camera is arranged in the passenger compartment, the possibility of being stolen can be reduced, and if a vibration or the like is applied to the host vehicle 1 for theft, a thief is photographed by the cameras 21a to 21f before theft.

  The photographing means 11 may be arranged outside the passenger compartment. For example, if the cameras 21a to 21f are arranged on the front bumper, the door, and the rear bumper, images of all directions can be similarly taken from the own vehicle. When arranged outside the passenger compartment, it is preferable to issue an alarm when vibration or the like is detected in order to prevent the cameras 21a to 21f from being stolen or damaged.

  Since it is preferable that the photographing unit 11 has already started photographing and recording when an impact due to contact and escape is detected, it is preferable to always continue photographing and recording when there is no passenger in the vehicle. In addition, since it is only necessary to capture and record the image data before and after the hit and escape, the image is taken in the same manner as a so-called drive recorder that keeps the latest recorded data and overwrites the old recorded data with the latest recorded data. . When shooting and recording are always continued as in a drive recorder, the shooting means 11 takes the shooting and shooting when detecting that the accessory switch is turned off and the vehicle door is opened or closed, or when the door lock is detected. Start recording.

  Moreover, since the imaging | photography means 11 should just have image | photographed the harm vehicle 10, various imaging | photography forms are applicable about how the imaging | photography means 11 image | photographs (henceforth imaging | photography form). A photographing form will be described. FIG. 4A shows a shooting mode in which the cameras 21a to 21f are always in shooting and recording states. As described above, in order to photograph the perpetrated vehicle 10 that has hit and escaped, it is preferable to always set the cameras 21a to 21f to the photographing and recording states, but this is not preferable from the viewpoint of power consumption, and is omnidirectional. Therefore, it is thought that there is little collision at about the same time. For this reason, the cameras 21a to 21f need not always be in the shooting and recording state.

  Therefore, the cameras 21a to 21f may be switched at a constant period to perform omnidirectional shooting. FIG. 4B shows a shooting mode in which the cameras 21a to 21f are switched at a constant cycle to set the shooting and recording state. In the shooting mode as shown in FIG. 4B, since only one camera performs shooting and recording at a certain time, power consumption can be reduced and the storage capacity of image data can be saved. Note that shooting and recording may be performed with a plurality of cameras at a certain time.

  Further, when shooting and recording are performed by switching at a constant cycle as shown in FIG. 4B, if a moving body is detected within a predetermined distance from the host vehicle 1, the direction in which the moving body is detected is shot. It is preferable to increase the number of photographing opportunities with the camera. Detection of the moving body may be performed by providing a light receiving element in a bumper or the like of the own vehicle 1 and the movement of the headlamp or the back lamp of the harming vehicle 10. Also good. A clearance sonar may also be used.

  When the moving body is detected, the photographing unit 11 increases the photographing opportunities of the camera that photographs the direction in which the moving body is detected. FIG. 4C shows an example of an imaging mode when a moving body is detected behind the vehicle at time t1. When a moving object is detected behind the vehicle, the camera 21e continuously captures and records images after time t1, and switches between the cameras 21c and 21f that capture images in the direction near the vehicle rear to alternately capture and record images. Do. Thereby, the harmful vehicle 10 can be reliably image | photographed, reducing power consumption.

  Further, after an impact due to contact and escape is detected by the impact detection means 12 described below, shooting and recording may be performed by a camera that captures the direction of the impact. FIG. 4D shows an example of a shooting mode when an impact is detected in front of the vehicle at time t2. When an impact is detected in front of the vehicle, the victim vehicle 10 can be photographed while reducing power consumption by continuously photographing and recording with the camera 21a and the camera 21b after time t2. In addition, you may image | photograph and record after the impact is detected with all the cameras 21a-21f.

  Further, when shooting and recording are started after the impact is detected, the camera is not arranged as shown in FIG. 3, and when the impact is detected, the camera is directed to the direction in which the impact is detected, and the recording is performed. The number of cameras to be arranged can be reduced.

  When the impact is detected, the photographing unit 11 continues the photographing for a predetermined time (for example, 1 to 2 minutes) after the impact is detected, and then finishes the photographing. As a result, the number plate of the hit-and-run vehicle and the driver can be photographed.

  The impact detection means 12 detects an impact due to contact and escape and also detects the direction in which the impact occurred. The impact detection means 12 is configured as a satellite sensor that turns on an internal switch to output an ON signal when a deceleration greater than a reference value is applied to the vehicle, or a touch sensor that conducts a contact when compressed. In the case of a satellite sensor, it is provided at a predetermined location inside the front bumper and the rear bumper, and in the case of a touch sensor, it is provided inside the front bumper and the rear bumper so as to cover substantially the entire length. When a load from the horizontal direction is applied to a part of the front bumper or the rear bumper, an impact is detected. The impact detection means 12 calculates from the magnitude of the impact detected by the plurality of satellite sensors, and detects the direction of the impact based on the conducting position. The detection contents of the impact detection means 12 are sent to the photographing means 11 and the harm content recording means 14.

  The image processing means 13 extracts the vehicle number of the offending vehicle 10 from the image data photographed by the photographing means 11 by image processing. In the image processing means 13, the number plate was photographed at an appropriate angle from a series of recorded image data in order from a predetermined time before the time when the impact occurred (after the impact detection in the case of capturing from the impact detection). Extract image data. Next, a number plate is cut out from the image data, and the inside of the number plate is subjected to OCR processing to extract a vehicle number consisting of a land support code, a vehicle type code, a use code, and a serial number. The extraction of the vehicle number may be performed at the security center or may be recognized visually by the user or the like.

  Further, the image processing unit 13 sequentially starts from a predetermined time before the time when the impact occurred (after the impact is detected when the image is captured from the impact detection), and from the series of recorded image data, the image data obtained by capturing the driver. To extract. The image data obtained by photographing the driver may be extracted from the image data obtained by extracting the vehicle number, or the characteristics of the image obtained by photographing the driver and the vehicle in advance are patterned and statistically matched (the driver takes the image). Image data that is highly likely to be generated) may be extracted.

  When the impact detection means 12 detects an impact, the harm content recording means 14 records the time (time stamp) when the impact was detected, the direction and magnitude of the impact, and the vehicle number (hereinafter referred to as the harm content). . About the time when the impact was detected, it is preferable to receive time authentication by a time authentication server in order to ensure evidence capability.

  The harm information transmitting means 15 transmits the content of the harm related to the escape to the user of the own vehicle 1 and the security center 2 and image data of the harmed vehicle photographed by the photographing means 11. At least the fact that there was an impact on the user, information that identifies the offending vehicle 10 is transmitted to the security center 2. When the transmission capacity of the image data is large, a part of the image data is transmitted according to the maintenance of infrastructure facilities such as communication means.

  FIG. 5A shows an example of impact detection information transmitted to the user. The impact detection information includes the impact detection time, the magnitude of the impact, the number of the harming vehicle, and the image 25 of the harming vehicle. The user can receive the shock detection information and know the fact of the shock, the degree of the shock, and the number of the vehicle to be damaged. Further, if there is an image 25 of the harming vehicle, the vehicle type and the color of the vehicle can be determined. In addition, you may transmit the image 25 of a harm vehicle as a moving image.

  FIG. 5B shows an example of an impact record transmitted to the security center 2. The impact record includes the impact detection time, the magnitude of the impact, the number of the harming vehicle, the parking position, the location where the impact occurred, and the image 25 of the harming vehicle. The parking position is recorded based on the satellite positioning information received from the GPS satellite immediately before parking. The security center 2 can identify the offending vehicle based on the impact record, and can identify the person who was driving the offending vehicle 10 by the driver shown in the image 25 of the offending vehicle. The user can claim compensation for damage to the host vehicle due to hitting and escaping based on the address of the user of the offending vehicle 10 investigated by the security center 2. In addition, you may transmit the image 25 of a harm vehicle as a moving image.

  Note that any communication means such as a mobile phone network, a PHS network, and a wireless LAN may be used as the transmission means for transmitting to the user or the security center 2. In the present embodiment, the number of the vehicle is extracted by image processing. However, if the electronic number plate has an IC chip embedded in the number plate, the number of the offending vehicle 10 can be easily obtained.

  Based on the above configuration, the procedure of the process of identifying the vehicle that the aggression detection device hits and escapes will be described based on the flowchart of FIG. The process shown in the flowchart of FIG. 6 starts when, for example, the passenger gets out of the vehicle and the door is locked. When the process is started, the harming action detection device repeats the determination of whether there is a moving body approaching or not, depending on whether there is a moving body approaching a predetermined distance or less by radar or clearance sonar (S11).

  When there is an approaching moving body (Yes in step S11), the photographing unit 11 directs the camera in the approaching direction of the moving body and starts photographing and recording (S12). When a moving body is detected, shooting and recording may be performed with all cameras mounted on the vehicle.

  Next, the harming action detection device determines whether or not the relative speed of the moving body is equal to or higher than a predetermined reference value (S13). The relative velocity of the moving object is calculated based on the displacement amount per unit time of the moving object detected by the radar or the clearance sonar.

  When the relative speed is equal to or higher than the reference value (Yes in step S13), the outside air bag in the approaching direction of the moving body provided in the vehicle is deployed (S14). The air bag outside the vehicle is installed in a bumper or a door, has a longer deployment duration than the air bag protecting the passenger in the vehicle, and prevents the perpetrating vehicle 10 from colliding with the host vehicle 1 in advance. The impact on the host vehicle 1 is reduced. If the relative speed is smaller than the reference value (No in step S13), the possibility of causing great damage to the host vehicle 1 is small, so the air bag outside the vehicle is not deployed.

  Next, the impact detector 12 determines whether or not an impact has been detected (S15). When an impact is detected, the photographing opportunity in the direction in which the impact has occurred is increased as described above, and the time when the impact is recorded is recorded by the harm content recording means 14. Moreover, the image processing means 13 extracts the number of the harm vehicle 10 and the image of the driver taken from the imaged image.

  Next, the harming action detection device determines whether there is an occupant in the passenger compartment of the host vehicle 1 based on the load in the seat or the like (S16). If the driver stays in the passenger compartment even after the door is locked, or if the driver gets off the vehicle but other passengers remain in the passenger compartment (Yes in step S16), the in-vehicle airbag at the place where the passenger is present is deployed (S17). . Thereby, even if there is a big impact, the passenger | crew of the own vehicle 1 is protected. In addition to the airbag, a device that reduces whiplash may be activated.

  If there is no occupant in the passenger compartment of the host vehicle 1 (No in step S16), the harm information transmitting means 15 transmits the impact detection information to the user and the impact record to the security center 2 (S18). Thereby, the user can recognize that there was a hit and escape, and the security center 2 can specify the injurious vehicle. Note that even if there are passengers in the vehicle compartment, the impact detection information and impact records may be transmitted to the user or the security center 2.

  According to this embodiment, even if the host vehicle is hit and escaped, the vehicle number and image of the offending vehicle are recorded, so that the offending vehicle can be identified and the damage caused by the damage can be compensated. Unlike the compensation of repair charges by vehicle insurance, you can ask the perpetrator for repair charges, etc. by asking the responsibility of the perpetrator for civil reasons, and can impose administrative responsibility on the perpetrator.

  In the present embodiment, a description will be given of an aggression detecting device that detects a mischief such as graffiti on the own vehicle 1 that is parked and stopped and notifies the user or the security center 2 of this.

  The functional block diagram of the harmful action detecting device of the present embodiment is the same as that of FIG. 2, but the impact detection means 12 detects the minute vibration of the vehicle, and the vibration detected by the minute vibration detection means. Vibration integrating means for integrating the magnitude of.

  When the subject vehicle 1 is scribbled with a ten-yen coin or the like, it can be assumed that the subject vehicle 1 is subjected to a stimulus that is smaller than the contact escape but longer in time. Therefore, the impact detection means 12 of the present embodiment detects a change in pressure due to vibration generated in the vehicle and a shake of the vehicle body, and determines that the host vehicle 1 has been damaged when such a stimulus is detected.

  FIG. 7 is an example of a diagram showing the relationship between the magnitude of impact and time when graffiti is drawn. For comparison, FIG. 7 shows the impact caused by the contact and escape. The impact of hitting and escaping gives a large impact in a short time. The impact detection means 12 determined that the injurious vehicle 10 was in contact with the host vehicle 1 when the impact exceeded a threshold value for detecting escape.

  On the other hand, in the case of graffiti, a small impact is detected for a long time. The impact detection unit 12 integrates the stimulus value sch with time, and detects that the scribble is drawn when the integrated value becomes larger than the predetermined value Sc.

また、より簡単には、小さい衝撃が所定時間Ｔｃよりも長い時間検出された場合、落書きされていると検出してもよい。

ｓｃｈが検出されている時間ｔ ＞ Ｔｃ …（２）

これらの閾値Ｓｃ、Ｔｃは、落書きによる衝撃の大きさや時間の統計を予め算出しておき、落書きの振動に相当する衝撃を抽出する。例えば、道路を走行する他の車両の振動や風による刺激（以下、外乱という）と区別して抽出される。また、落書きは人によりなされるので、振動の検出に加えて赤外線センサを併用し、赤外線が熱源である人を検出した場合に振動を検出することとしてもよい。

Further, more simply, when a small impact is detected for a time longer than the predetermined time Tc, it may be detected that a graffiti is drawn.

Time when sch is detected t> Tc (2)

For these threshold values Sc and Tc, statistics of the magnitude and time of impact due to graffiti are calculated in advance, and impact corresponding to graffiti vibration is extracted. For example, it is extracted separately from vibrations or wind stimulation (hereinafter referred to as disturbance) of other vehicles traveling on the road. In addition, since graffiti is made by a person, in addition to detecting vibration, an infrared sensor may be used in combination, and vibration may be detected when a person whose infrared is a heat source is detected.

  Since the impact detection means 12 continuously performs the determination according to the formula (1) or (2) during parking and stopping, if the parking and stopping time becomes long, there is a possibility that a disturbance is detected as graffiti even if it is not graffiti. Arise. For this reason, in the determination by the formula (1) or (2), it is preferable to reset the integrated value or detection time of sch when sch is no longer detected.

  However, since graffiti is often performed intermittently, as shown in FIG. 7, even if vibration is no longer detected at time t3, it may be resumed at time t4. Since the graffiti cannot be detected by resetting the integrated value or detection time of the sch for such graffiti, if the value of | t4-t3 | is within the predetermined time, the integrated value or the detection time is not reset without resetting the integrated value or detection time of the sch. Measure the detection time. Thereby, intermittent graffiti can be detected with high accuracy. In order to detect graffiti early, sch ′ between t3 and t4 may be interpolated, and the integrated value may be added to equation (1) and | t4-t3 | may be added to equation (2).

  Whether or not graffiti is intermittently performed is determined by comparing | t4−t3 | with a predetermined threshold value in the same manner as the determination of disturbance and graffiti.

  When the impact detection means 12 detects graffiti, the imaging means 11 starts to capture an image in the vehicle outward direction unless it has been captured. As in the first embodiment, the photographing unit 11 may always perform photographing like a drive recorder, or may photograph by periodically switching the photographing direction, or after the vibration is detected. May start. In the case of graffiti, the image processing means 13 does not extract the vehicle number and extracts an image in which the person who has graffiti is photographed.

  When the impact detection means 12 detects graffiti, the harm content recording means 14 records the direction of impact, if possible, along with the time of graffiti (time stamp).

  The harm information transmission means 15 transmits information regarding graffiti to the user of the host vehicle 1 and the security center 2. FIG. 8A shows an example of graffiti detection information transmitted to the user. The graffiti detection information includes a graffiti detection time and a graffiti person image 26. The user can know the face of the graffiti by receiving the graffiti detection information. In addition, you may transmit the image 26 of a graffiti person as a moving image.

  FIG. 8B shows an example of a graffiti record transmitted to the security center 2. The graffiti record includes a graffiti detection time / parking position and a graffiti person image 26. The parking position is recorded based on the satellite positioning information received from the GPS satellite immediately before parking.

  In the case of a graffiti person, unlike the hitting and hurting vehicle 10, it is difficult to find the location later after leaving the graffiti site, so it is preferable to secure the site as soon as possible. For this reason, for example, the security center 2 contacts the nearest security center branch based on the parking position, promptly dispatches security personnel, and reports to the nearest police. In addition, you may transmit the image 26 of a graffiti person as a moving image.

  Based on the above configuration, the procedure of the process in which the perpetrator detecting device records the graffiti will be described with reference to the flowchart of FIG. The process shown in the flowchart of FIG. 9 starts when, for example, the passenger gets out of the vehicle and the door is locked. When the process is started, the harming action detection device captures and records all directions of the vehicle while periodically switching the camera to be photographed (S21). Since at least one camera shoots the surroundings of the vehicle, it is possible to record an image before it is graffitied. Thereby, when the graffiti is detected, it is possible to prevent the graffiti from being recorded because the graffiti is already finished.

  The impact detection means 12 repeats the determination of whether there is a graffiti stimulus (S22). When the graffiti is detected (Yes in step S22), the photographing unit 11 increases the chance of photographing the graffiti direction if the graffiti direction is known (S23). In addition, you may image | photograph all the directions of a vehicle with all the cameras mounted on the vehicle.

  Next, the image processing means 13 extracts the image of the graffiti photographed from the photographed image (S24). As a result, an image of the graffiti was taken and recorded. Moreover, the harm content recording means 14 records the doodled time. From the viewpoint of privacy protection, when a person who is not a graffiti is recorded in the image data, it is preferable to delete the image every predetermined time or when the driver returns to the vehicle.

  When the image of the graffiti is extracted, the harm information transmitting means 15 transmits the graffiti detection information to the user and the graffiti record to the security center 2 (S25). Thereby, the user can recognize that there was a graffiti, and the security center 2 can dispatch security guards etc. to the own vehicle 1 immediately.

  According to the present embodiment, when a graffiti is drawn on the host vehicle, an image of the graffiti can be recorded. Since the image of the graffiti is transmitted to the security center 2, it is possible to dispatch security guards and the like immediately to the graffiti site. Similar to the first embodiment, unlike the compensation of the repair fee by vehicle insurance, it is possible to ask the victim vehicle for the repair fee and the like by asking the responsibility of the civil perpetrator.
