The stolen vehicle is recovered by contacting and returning to the stolen vehicle early. However, in this case, even if the owner of the vehicle returns to the stolen vehicle at an early stage, an unauthorized person involved in the theft cannot be cleared.

Furthermore, in Japanese Patent Application Laid-Open No. 2004-122969 (Patent Document 2), a camera is installed in a vehicle, a crew member is recognized by the camera, and a face image of the unauthorized person is taken into a storage device if the person is an unauthorized person involved in theft. Furthermore, a device is disclosed in which a wireless communication device is provided and a captured image is transmitted to the outside.
However, in this way, the type that receives and records the face image of an unauthorized person involved in the theft through communication obtains the face image etc. of the unauthorized person involved in the theft when the data transmission location is within the communication range. Although it is possible, if it is outside the communication area such as an underground parking garage, communication cannot be performed, and a face image of an unauthorized person involved in theft may not be recorded.

  Further, when a stolen vehicle is found, if the vehicle captures and records a face image of an unauthorized person involved in the theft in the vehicle, when the recording device is recovered, the face image of the unauthorized person involved in the theft is displayed. It is possible to confirm, but in this case, unless a stolen vehicle is found, the face images of these stolen illegal persons cannot be confirmed.

  Such a vehicle antitheft device of FIG. 1 causes vehicle body vibration and in-vehicle noise due to destruction of doors and front / rear window glass (not shown) when the vehicle is stopped and the engine is stopped in the door locked state when the vehicle is stopped. If it is determined that at least one exceeds the threshold value, then when the determination control circuit 36 receives information from the engine ECU 37 that the vehicle has started running (when the engine is started), a shooting command F is sent to the camera 4. When the camera 4 shoots an unauthorized person involved in the theft and transmits it to the recording device 6, the recording device 6 takes in the person image data and stores it in the write-only separation memory 8. The discrimination control circuit 36 outputs a discharge command C to the coil drive circuit 33 at a time corresponding to the storage process of the recording device 6. Thus, the normally closed first contact e1 is opened, the normally opened second contact e2 is closed, the solenoid 18 is de-energized, the separation memory 8 is separated from the connection socket 13, and the lever solenoid 29 is driven to operate. By rotating the lever 27, the cover 16, the lid member 15 and the separation memory 8 are simultaneously separated from the connection socket 13 in the initial region r2, and the cover 16 and the cover member 15 are further separated from the connection socket 13 by the subsequent rotation. The separation memory 8 is pushed out from the lid member 15 and the cover 16 side by the elastic force of the spring 25 and is released below the normally closed long hole 14.

  Since the falling position of the separation memory 8 is an area immediately after the vehicle starts running, the separation memory 8 can be found relatively easily. Further, if the separation memory 8 is ejected outside the vehicle before starting the vehicle, there is a high risk that an unauthorized person involved in theft will perceive the separation memory 8 being ejected. It discharges outside the car.

The transmission signal D is received by the first communication means 45, which is the PHS or mobile phone receiving terminal, via the PHS or mobile phone communication network (step a5). Then, the transmission signal D is input to the vehicle theft control means 41d, and in response to this, the vehicle theft control means 41d outputs a release command C to the coil drive circuit 33 of the release means 12. As a result, the separation memory 8 in which the image data of the person who was in the driver's seat at the time when the vehicle started running is released below the normally closed long hole 14 (step a7).

Also in this case, substantially the same operation and effect as the vehicle antitheft device 4a of the second embodiment of the present invention shown in FIG. 2 can be obtained. In particular, the first communication means 45 can set the fall time of the separation memory 8. This is advantageous in that it is easy to specify the falling location of the separation memory 8.
FIG. 7 shows a vehicle antitheft device 4e as the sixth embodiment. This vehicle anti-theft device 4e has many members having the same configuration as the vehicle anti-theft device 4d as the sixth embodiment of FIG. 6, and here, the same members are denoted by the same reference numerals, and redundant description is omitted.

Here, the vehicle antitheft device 4e includes a recording device 6, a vehicle theft determination unit 7, a vehicle theft control unit 41e, a position information acquisition unit 45 for acquiring vehicle position information, a second communication unit 46, and a release unit. 12. An ECU 37 that is an engine control device is connected to the vehicle theft control means 41e.
The second communication means 46 is a transmission terminal, and has the same configuration as the PHS or mobile phone transmission terminal. Via the communication network of the PHS or mobile phone, the immediately preceding position information (longitude: Xn, latitude: Yn) is transmitted to the receiving terminal SS of the management center of the vehicle antitheft device 4e. The management center reads the position on the map corresponding to the received vehicle position information (Xn, Yn).

  The position information acquisition means 45 records the GPS receiver 47 that can detect the current position of the vehicle based on the position signal sent from the GPS satellite 52 and the vehicle position information (longitude and latitude) obtained by the GPS receiver 47. And a function of recording the vehicle position information (longitude: Xn, latitude: Yn) when the position information acquisition command J is received from the vehicle theft control means 41e, and is connected to the vehicle theft control means 41e. Is done.

  Here, the vehicle theft control means 41e issues a position information acquisition command J to the position information acquisition means 45 prior to the output of the release command C, which is immediately before operating the release means 12, and the position information (Xn, Yn immediately before the release). ) And the previous position information (Xn, Yn) is transmitted via the second communication means 46 via the PHS or mobile phone communication network.

It is assumed that the vehicle equipped with the vehicle antitheft device 4e as the sixth embodiment is stolen.
In this case, a theft prevention control routine of steps b1 to b7 as shown in FIG. 11 is executed. First, the determination circuit 36 of the vehicle theft determination means 7 determines whether or not the vehicle body vibration and the vehicle interior noise from the G sensor 34 and the noise sensor 35 exceed a threshold value, and if so, the determination control circuit 36 outputs a theft signal c2. Thereafter, the vehicle theft control means 41 d outputs a photographing command to the camera 3 and the recording device 6 when it detects that the vehicle has started to travel. Thus, an image of the person in the driver's seat is taken by the camera 3 (step b2), and the person image data is stored in the separation memory 8.

  In response to this, the vehicle theft control means 41d issues a position information acquisition command J to the position information acquisition means 45 prior to outputting the release command C to the release means 12. The position information acquisition means 45 acquires the current position of the vehicle as position information (Xn, Yn) immediately before the release according to the position signal sent from the GPS satellite, and records it in the recording unit 48 (step b4). Thereafter, the theft control means 41d transmits the position information (Xn, Yn) immediately before the release via the PHS or the mobile phone communication network via the second communication means 46 (step b5).

Thereafter, the vehicle theft control means 41e outputs a release command C to the release means 12, whereby the separation memory 8 in which the image data of the unauthorized person is recorded is released below the normally closed slot 14. (Step b7).
On the other hand, the management center of the vehicle antitheft device 4e on the PHS or mobile phone communication network receives the vehicle position information (longitude: Xn, latitude: Yn), reads the position on the map, and the position information is the vehicle theft. It is provided to the owner side of the stolen vehicle that is the user of the prevention device 4e. Thereby, the owner side of the stolen vehicle can reach the vicinity of the drop position of the separation memory 8 at an early stage, and the separation memory 8 can be collected.

The vehicle antitheft device 4e as the sixth embodiment of FIG. 7 can obtain substantially the same operation and effect as the vehicle antitheft device 4d of the fifth embodiment of the present invention shown in FIG. Thus, the separation memory 8 can be collected early.
FIG. 8 shows a modified example of the vehicle antitheft device 4e shown in FIG. Since the vehicle antitheft device 4f is different from the vehicle antitheft device 4e of FIG. 7 only in the separation memory 8f, the same members are denoted by the same reference numerals, and redundant description is omitted here.

Here, the separation memory 8f of the vehicle antitheft device 4f is different from the separation memory 8 of FIG. 3 in that an in-device power supply 49 and a small transmitter 50 are added, and other configurations are the same. The duplicate description is omitted.
In the separation memory 8f, a recording circuit portion 802 is accommodated in a metal casing 801, and a joint portion 22 is formed at one end in the longitudinal direction. In addition to the contact train extending from the circuit side of the recording circuit unit 802, the joint unit 22 includes a power supply extension circuit 51 that reaches the transmitter 50 via the in-device power supply 49. The in-device power supply 49 is constantly supplied with power from the power supply circuit 5 and can supply power to the small transmitter 50.

  The small transmitter 50 is formed so that the antenna 53 protrudes outside the casing 801 and transmits radio waves of a specific frequency, and particularly includes a normally closed switch circuit 54. The normally closed switch circuit 56 is formed to be turned on when the separation memory 8f is detached from the lid member 15 and the cover 16 side and to start a transmission operation.

  As a result, when the vehicle theft control means 41f releases the separation memory 8f in which the image data is recorded in response to the release command C, below the normally closed long hole 14, the separation memory 8f is specified by the antenna 53. Transmits radio waves of a frequency. For this reason, it is very easy to detect and collect the separation memory 8f by using a radio wave detector of a specific frequency, identify an unauthorized person involved in the theft, and facilitate an investigation of the unauthorized person involved in the theft. It is possible to prevent vehicle theft.
