Description

  The present invention relates to a vehicle monitoring device that can be installed in all vehicles, and relates to a vehicle theft monitoring device that monitors the entry of an object into a vehicle.

  In recent years, crime prevention devices using immobilizers have become widespread. Therefore, even if the immobilizer is attached, the vehicle theft cannot be completely prevented, and the immobilizer alone cannot cope with the vandalism aiming at the hardware, accessories, etc. in the vehicle. In addition, since theft that does not know how the theft was performed has occurred, various antitheft devices are being sought.

  Conventionally, a system that informs the surrounding people of theft by sounding a siren or flashing a light when the door is opened without using a regular key, even when the vehicle is locked. It has been realized. An apparatus for constantly monitoring the inside and outside of a vehicle with a security camera installed in the vehicle is also known (see, for example, Patent Document 1). In addition, people and objects approaching the vehicle are sensed by a sensor, threatened with an alarm, etc., and imaged by an imaging device, thereby monitoring mischief such as graffiti on the vehicle and puncturing the tire, There is known a device that issues an alarm even when an object enters the vehicle, images the interior of the vehicle, and wirelessly transmits the captured information to the vehicle management center (see, for example, Patent Document 2).

  Then, according to such an anti-theft device, an object approaching the vehicle can be detected during monitoring and a threatening alarm can be issued or imaged. By taking an image and transferring the image information to a monitoring center or the like, the occurrence of a vehicle theft case can be suppressed.

  As in the above prior art, the sensor senses when an object approaches the vehicle and alerts / reports or picks up an image with an imaging device.In a narrow parking lot, when a neighbor stops the vehicle next to it, There is a risk that the sensor reacts every time a person who is simply interested in the vehicle and looks into the vehicle will take an image, false alarm, or false report.

  In addition, in an anti-theft device that detects intrusion of a vehicle by an intrusion sensor that detects intrusion into the vehicle by an ultrasonic sensor or a pyroelectric sensor that senses infrared rays emitted from a human body, the intrusion sensor is usually noticed by a person. Although it is installed in a difficult place, there is a possibility that the intrusion sensor may find the sensor itself and be destroyed before detecting the intrusion of the object into the vehicle. There is a problem that the means for detecting is extremely lost.

  Further, these intrusion sensors detect the intrusion of an object into the vehicle, and cannot detect that a heavy object is taken out of the vehicle.

  The present invention has been made in view of the above problems, and an object of the present invention is to construct an intrusion detection means that reliably detects an intrusion of an object into a vehicle.

  Furthermore, the present invention is intended to prevent vehicle theft and on-vehicle damage.

  In order to achieve the above object, means for detecting a state where the vehicle is door-locked, means for determining whether or not a key for locking is used, and when the locking key is not used, Provided with a plurality of sensors for detecting changes, and at least one sensor is a weight sensor, detects the weight applied to the seat, and is mounted on the vehicle when any of the plurality of sensors detects a change in the vehicle. A vehicle theft monitoring device, wherein the image pickup / recording device is activated and imaged / recorded.

  As one intrusion sensor, a weight sensor is built in the seat.

  According to this, as a means for detecting the intrusion of an object into the vehicle using the weight sensor, the weight currently applied to the seat is detected, and the ECU (electronic control device incorporating a microcomputer) is output from the weight sensor. An output value (hereinafter referred to as “weight value”) is stored in the memory, and an absolute value of a difference between the current weight value and the stored weight value before the predetermined time is calculated after a predetermined time has elapsed. If the absolute value of the difference between the weight values exceeds a predetermined value, it can be recognized that there is some abnormality in the vehicle. Some kind of abnormality means that the weight is applied to the seat or that the weight applied to the seat is lost, that is, the weight applied to the seat changes, and it is abnormal because the predetermined value described above can be set arbitrarily. It can be detected.

  In addition, it is possible to detect at least that a person is sitting on the seat and that a heavy object on the seat has been taken away, and when the intrusion of an object into the sensor vehicle is detected, the imaging / recording device is activated. Thus, the inside of the vehicle is monitored by starting imaging / recording.

  The intrusion detection and imaging / recording device activation processing described above is controlled by the ECU.

  According to this, it is possible to detect that an object has entered the vehicle without using the regular key, even though the vehicle is locked, and the information obtained by imaging / recording the vehicle at that time can be detected. You can get it.

  According to the present invention, at least one of a plurality of sensors that detect a change in the vehicle is a weight sensor that detects the weight of the seat, thereby allowing entry into the vehicle and taking out heavy objects (luggage) from the vehicle. It can be accurately grasped.

  Examples of the present invention will be described below.

  FIG. 1 is a system configuration diagram showing the overall configuration of a theft monitoring system according to an embodiment to which the present invention is applied.

  The vehicle includes an electronic key system 1, an intrusion sensor 2 (and 21 to 24), a weight sensor 3, a GPS terminal 4, an ECU 5, an imaging / recording device 6, a storage device 7, and a communication device 8. The theft monitoring device 9 is mounted, and wireless communication is performed between the communication device 8 and the base station 10 managed by the monitoring center 11, and the monitoring center 11 communicates with the vehicle owner 13, the security company / police station 14, and the Internet network 12. This means that information can be exchanged via.

  The electronic key system 1 transmits and receives IDs (key-specific information) between an electronic key (not shown) and a transmission / reception unit (not shown) inside the door, and is stored in advance in the electronic key ID and ECU. It is a system in which the door lock is released and the door can be opened only when the ID is matched and the ID matches.

  In addition, the electronic key automatically transmits / receives ID information to / from the electronic key system 1 to automatically unlock the door when the owner approaches the vehicle (the situation where the owner exists within the communication range). When a predetermined distance (communication range) is away from the door, the door is automatically locked.

  When the electronic key system 1 receives the door opening / closing information using the electronic key of the regular ID, the ECU 5 performs processing for switching the security mode ON / OFF of the theft monitoring device 9.

  As shown in FIG. 2, one or more intrusion sensors 21 to 24 are arranged in the vehicle so that intrusion detection can be performed from the front, rear, left and right of the vehicle. Further, a weight sensor 3 for detecting the weight applied to the sheet is built in all the sheets.

  More specifically, the intrusion sensors 21 to 23 are installed as shown in FIG. 3, and the imaging / recording apparatuses 61 to 64 are installed in a place where it is difficult for third parties to notice. In particular, in the image pickup / recording devices 61 to 64, it is preferable to use a micro CCD camera. Furthermore, it is preferable that a wide-angle lens or a panoramic image can be captured, and that an image can be captured at night like an infrared camera.

  FIG. 4 shows intrusion detection processing executed in the weight sensor 3. When the door is locked with the electronic key, in S3, the weight sensor 3 detects the weight currently applied to the seat, and if the weight value is less than the predetermined value A stored in the ECU 5 in advance, the security mode ON ( If the monitoring state is equal to or greater than the predetermined value A, the security mode is OFF (unmonitored state).

  Specifically, the weight value when at least one person is in the vehicle is set to a predetermined value A. Then, since the weight value when the door is locked becomes less than the predetermined value A when an object (including at least a human) is out of the vehicle, the security mode is turned on. If the weight value when the door is locked is greater than or equal to the predetermined value A, it means that an object (including at least a human) has not left the vehicle or has newly entered the vehicle, so the security mode remains OFF. maintain.

  For example, when an object (including at least a human) remains in the vehicle, the security mode ON / OFF can be switched by changing the predetermined value A.

  More specifically, even if the door is locked with a human being left in the vehicle, the security mode is maintained OFF, for example, a child seat is installed, and at least the seat is heavy in the vehicle. If the door is locked when no one is present, the security mode can be turned on.

  A series of processes of S1 to S5 is a malfunction prevention process of the theft monitoring device 9.

  As described above, when a person is left in the vehicle and the electronic key owner locks the door and the person in the vehicle tries to go outside, or a heavy load on the seat Etc. (specifically, a child seat or the like is installed), the theft monitoring device 9 will not malfunction.

  In S6, when the security mode is ON, the ECU 5 stores an output value (hereinafter referred to as “weight value”) output by the weight sensor 3 in a memory (not shown), and the current weight value after a predetermined time has elapsed. And the absolute value of the difference between the stored weight value before the predetermined time. If the absolute value of the difference between the weight values exceeds the predetermined value B, it can be recognized that the vehicle has entered the vehicle, so the imaging / recording / communication process of S10 is performed. By being able to arbitrarily set the predetermined value A and the predetermined value B described above, at least a person sat on the seat, or a heavy object (such as a bag) was placed on the seat, and it was taken away (caring on the vehicle) Can be detected.

  By the series of processes of S1 to S10, it is possible to realize means for detecting intrusion and roughing on the vehicle by the weight sensor according to claims 2 and 3.

  Preferably, the above-mentioned predetermined values A and B (threshold values) of the weight value can be set on the monitor screen of the car navigation system, and a password or the like is used so that only the owner can set it.

  In the above intrusion / car roughening detection process, the imaging / recording / communication process of S10 is the process from S14 shown in FIG.

In S14 to S18, the intrusion sensor 2 (and 21 to 21) described above during the security mode.
24) When an intrusion into the vehicle is detected by at least one of the weight sensors 3, an activation signal is sent from the ECU 5 to the imaging / recording device 6 to start imaging / recording.

  Simultaneously with the intrusion detection, the current position, time, and movement trajectory information are measured and calculated by the GPS terminal 4 or the like. Those pieces of information are divided into predetermined time intervals (set as one file) and stored in the storage device 7.

  In S19 to S22, when an unsent file exists in the storage device 7, the communication device 8 performs automatic transfer to the base station 10 managed by the monitoring center 11 wirelessly via an existing packet communication network used for a mobile phone. Start. When communication is interrupted due to radio wave interference or the like, transfer is performed again after a predetermined time, and information is continuously sent until the transfer is completed. Since the image / audio information is stored every predetermined time, when one file is transferred, the remaining files are transferred sequentially, and the transferred files are not transferred again.

  As described above, the imaging / recording / communication function of the vehicle theft monitoring device 9 is realized by the processes of S14 to S22.

  According to the present embodiment, an object has entered the vehicle without using a regular key in spite of the door being locked (specifically, a person breaks the window glass, At least one of the intrusion sensor 2 (and 21 to 24) and the weight sensor 3 detects that the door lock is forcibly released and the vehicle has entered the vehicle. The intrusion sensor 2 (and 21 to 24) is mounted in the vehicle and transmits ultrasonic waves while the security mode is ON. When an ultrasonic wave transmitted from the intrusion sensor 2 (and 21 to 24) is blocked by an object (including a human being) crossing it, it can be recognized that it has entered.

  Further, when the weight sensor 3 detects a change in weight applied to the seat while the security mode is ON, it can be recognized that the vehicle has entered.

  As a result, a person who is familiar with the anti-theft device destroys the intrusion sensor 2 (and 21 to 24) that detects intrusion into the vehicle by an ultrasonic sensor or a pyroelectric sensor that detects infrared rays emitted from the human body. Even in such a case, the weight sensor 3 can detect intrusion into the vehicle, roughing on the vehicle aiming at heavy objects on the seat, and the like.

  When the ECU 5 detects an intrusion with at least one of the intrusion sensor 2 (and 21 to 24) and the weight sensor 3 described above, the ECU 5 sends an activation signal to the imaging / recording device 6, and the imaging / recording device 6 is activated. / Start recording.

  Since the electronic information such as the acquired image has a large file capacity, the memory of the microcomputer of the ECU 5 is insufficient, so the ECU 5 stores the acquired information on a hard disk or the like (for example, a hard disk type) after a predetermined time has elapsed after the start of imaging / recording This is stored in a large-capacity storage device 7 such as a free space of a hard disk of a car navigation system. The storage device 7 is preferably one that can withstand vibration during vehicle travel.

  Further, the GPS terminal 4 simultaneously performs current position positioning, time positioning, and calculation, and stores them in the storage device 7 in the same manner.

  In addition, it is preferable that the GPS terminal 4 is always activated during the security mode, and the current position of the vehicle is compared with the vehicle position before a predetermined time to check whether there is any change. From this confirmation, if there is a difference between the position of the vehicle before a predetermined time and the current position, it can be recognized that the vehicle itself has been stolen (vehicle movement by a tow truck or the like). By storing the current position of the vehicle every predetermined time, it is bundled and used as movement trajectory information. The movement trajectory information thus calculated is also stored in the storage device 7.

  In addition, vehicle information (vehicle type, license plate number, model, color, etc.) is stored in the storage device 7 in advance.

  The stored information is transferred by the communication device 8 to the base station 10 managed by the monitoring center 11 via an existing packet communication network used for a mobile phone. When communication is interrupted due to radio wave interference or the like, transfer is performed again after a predetermined time has elapsed, and information is continuously sent until the transfer is completed. Since the image / sound information is stored every predetermined time, when one file is transferred, the remaining files are transferred sequentially, and the transferred files are not transferred again.

  From the above, the function of the vehicle theft monitoring device 9 of the present invention is realized.

  According to this embodiment, the vehicle detects that an object has entered the vehicle without using a regular key, or that a heavy object on the seat has been removed, even though the door is locked. Since the inside of the vehicle can be imaged / recorded, the monitoring center 11 immediately contacts the vehicle owner 13 when such information is transferred from the vehicle, and determines that a person other than the vehicle owner 13 has entered the vehicle. In this case, it is possible to report to the security company / the police 14. The police can identify the person who has entered the vehicle based on the image / sound information from the monitoring center 11 and the person who has performed the vehicle theft and vandalism.

  By the way, in the present invention, a means for detecting a change in weight is used as a weight sensor. However, the sheet is filled with air, liquid, or the like, and a pressure change caused by applying it is detected. You may use the sensor which detects seating to a sheet | seat by detecting a shape change.

  In the present invention, the image / audio information is stored in the large-capacity storage device 7 such as a hard disk, but of course the image / audio information, the current position information, etc. transferred from the vehicle on the monitoring center 11 side are stored. May be.

  In the present invention, the GPS terminal 4 calculates the current position, time, and movement trajectory information. However, a “quasi-zenith satellite” scheduled to be launched in 2008 may be used in combination with GPS.

The “Quasi-Zenith Satellite” always uses the characteristics of the same sanitation located above Japan, exchanges images and tones with automobiles, etc. for almost the entire area of Japan, and is highly accurate, for example, positioning in units of 10 centimeters. In combination with GPS, the positional information error can be reduced to about a hundredths of centimeters, which is 1/100 of the current GPS ratio. Therefore, improvement in detection accuracy is expected.

  As described above, in the vehicle theft monitoring device 9 according to the present invention, even if the intrusion sensor 2 (and 21 to 24) mounted on the vehicle is destroyed before detecting the intrusion, the weight sensor 3 It is possible to detect that (including at least a human) has entered the vehicle.

  Further, since the imaging / recording device 6 is activated and imaging / recording is started when an intrusion is detected, there is no need to always activate and image / record. Therefore, the power consumption of the power supply source (not shown) for the imaging / recording device and the memory usage of the storage device 7 can be suppressed as compared with the theft monitoring device that always images.

  In addition, when the image / sound information or vehicle information is transferred from the vehicle, the monitoring center 11 contacts the vehicle owner 13 and determines that a person other than the vehicle owner 13 has entered the vehicle. Report to the company / police 14 and provide information. Therefore, not only the vehicle owner 13 but also the security company / police 14 can respond immediately.

  Moreover, even if the stolen vehicle is moving, the current position, time, and movement trajectory information of the vehicle are transferred to the monitoring center 11 every predetermined time, and the security company / police 14 is based on the information from the monitoring center 11. Since it is possible to track on-site express and stolen vehicles, it is effective for identifying vehicle theft persons.

  In addition, information may be exchanged directly between the vehicle and the security company / police 14, but by the monitoring center 11, an erroneous report to the security company / police 14 (vehicle theft or vandalism has been made. It is possible to prevent the notification).
