  By the way, in the apparatus described in the above document, the criminal has already entered the vehicle at the time of shooting the criminal of the vehicle theft. For this reason, for example, when the criminal intrudes into the interior of the vehicle and immediately removes the image collecting part, the photographing itself may be hindered by the criminal himself, and the criminal deterrence power is naturally limited.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a vehicle antitheft device that can identify a vehicle theft offender with higher crime deterrent power and enable vehicle antitheft control. There is to do.

Hereinafter, means for solving the above-described problems and the effects thereof will be described.
The vehicle anti-theft device that solves the above problems is provided in a vehicle equipped with a main battery that is used in normal times and a backup battery that is used in an emergency, and can take images outside the vehicle from an in-vehicle camera inside the vehicle. The vehicle theft deterrent device is closed by the in-vehicle camera on condition that a cover for opening and closing the main battery housing chamber is closed in a state where power supply from the main battery is cut off. An image outside the vehicle on the cover side is taken, and the taken image is transmitted to a device outside the vehicle.

  In general, as one of vehicle theft techniques, there is known a technique for first removing from a vehicle a main battery that is often used as a power source for the alarm system for the purpose of not operating a vehicle alarm system or the like. With this technique, a special vehicle operation that cannot normally be assumed is performed such that the cover of the storage chamber of the main battery is closed while the power supply from the main battery is cut off. Therefore, in the above configuration, on the condition that such a special vehicle operation is performed, an image outside the vehicle on the closed cover side is photographed from the in-vehicle camera inside the vehicle using the electric power stored in the backup battery. Like to do. This photographed image usually shows the figure immediately after closing the cover of the criminal who tried to steal the vehicle, which is useful information for identifying the criminal who tried to steal the vehicle. Then, by transmitting such an image to a device outside the vehicle, it is possible to identify and track a criminal who has attempted to steal the vehicle. In the above configuration, when the in-vehicle camera takes a picture of a criminal who tries to steal the vehicle, the criminal is located outside the vehicle, and the in-vehicle camera is isolated from the criminal. Therefore, even if the criminal notices the presence of the in-vehicle camera when closing the cover, it is difficult to immediately remove the in-vehicle camera from the vehicle. Therefore, it becomes possible to identify the culprit of vehicle theft with higher crime deterrent and deter the vehicle from theft.

It is. When the anti-theft device 100 captures an image of a criminal who is attempting to steal the vehicle 200, the anti-theft device 100 wirelessly transmits the captured image to a theft tracking service provider outside the vehicle through wireless communication. The anti-theft device 100 is connected to various in-vehicle devices and a sensor group for controlling the operation of these in-vehicle devices via a vehicle network NW such as a CAN (Controller Area Network). And it is possible to grasp the situation of the vehicle 200 at the time of theft based on the output results from these sensor groups. In FIG. 1, for convenience, the sensor group is illustrated as if it is directly connected to the vehicle network NW, but actually, the sensor group controls the operation of various in-vehicle devices of the vehicle 200 ( It is connected to the vehicle network NW via an electronic control unit.

  The anti-theft device 100 includes an arithmetic unit 101 that performs various arithmetic processes in an integrated manner. The calculation unit 101 acquires an image outside the vehicle acquired from the in-vehicle camera 130 inside the vehicle through the image data acquisition unit 102, at that time, from the antenna 103 for GPS (Global Positioning System) through the position information acquisition unit 104. The information is written in the storage unit 105 in association with the position information of the vehicle 200. In addition, the calculation unit 101 reads the image stored in the storage unit 105 in association with various information such as the position information of the vehicle 200 and the vehicle ID that is the individual identification information of the vehicle 200 during the image transmission process. The read information is wirelessly transmitted through the mobile phone network communication unit 106.

  The anti-theft device 100 also includes a power management unit 108 that manages power between the main battery 131 used in normal times and the backup battery 107 used in emergency. When the main battery 131 is used as the power source of the anti-theft device 100, the power management unit 108 monitors the voltage value output from the main battery 131 and sends a signal indicating the monitored voltage value to the arithmetic unit 101. Output. The power management unit 108 also switches the power of the theft deterrent device 100 from the main battery 131 to the backup battery 107 when the supply of power from the main battery 131 is interrupted due to, for example, the main battery 131 being removed from the vehicle. Switch.

  The anti-theft device 100 includes a vehicle network communication unit 109 connected to the sensor group described above via the vehicle network NW. The sensor group described above includes an approach detection sensor 141 for detecting the approach of an object existing around the vehicle, in addition to a sensor for detecting the traveling state of the vehicle, such as a vehicle speed sensor 140 for detecting the vehicle speed of the vehicle 200, A bonnet opening / closing sensor 142 for detecting the opening / closing operation of the bonnet and a trunk opening / closing sensor 143 for detecting the opening / closing operation of the trunk are included. The proximity detection sensor 141 is, for example, a millimeter wave radar that measures a distance from an object existing around the vehicle, and outputs a detection signal to the vehicle network communication unit 109 when an object existing around the vehicle is detected. The bonnet open / close sensor 142 and the trunk open / close sensor 143 are mechanical or optical sensors, and output detection signals to the vehicle network communication unit 109 when an open / close operation of the bonnet or trunk is detected. The anti-theft device 100 includes a vibration sensor 110 that detects the vibration of the vehicle 200 in addition to the bonnet opening / closing sensor 142 and the trunk opening / closing sensor 143 described above. The vibration sensor 110 outputs a detection signal to the vehicle network communication unit 109 when detecting vibration characteristics peculiar to the opening / closing operation of the hood or trunk.

  As shown in FIG. 2, when the hood B is opened, the person P is hidden by the hood B when the person P is in front of the vehicle. Therefore, in the state where the bonnet B is opened, the person P is not included in the image of the in-vehicle camera 130 (FIG. 1) that is photographing the front of the vehicle. Therefore, in the present embodiment, when a person is included in the image of the in-vehicle camera 130, it is also possible to detect the opening / closing operation of the hood B based on whether or not the person has disappeared from the image.

  Further, as shown in FIG. 1, the anti-theft device 100 includes an encryption communication unit 111 connected to an immobilizer ECU 132 that controls the collation operation of the electronic key of the vehicle 200 and an engine ECU 133 that controls the operation of the engine of the vehicle 200. It has. When the immobilizer ECU 132 collates the electronic key, the encryption communication unit 111 relays the encrypted signal output from the immobilizer ECU 132 to the engine ECU 133 to indicate the start of the engine.

FIG. 3 shows a configuration example of a theft deterrence system for performing image transmission processing from the vehicle 200 to the theft tracking service provider.
As shown in FIG. 3, in this theft deterrence system, when the vehicle 200 that is the subject of the theft captures the thief, the captured image is wirelessly transmitted from the vehicle 200 to the base station A via the mobile phone network. The The information wirelessly transmitted to the base station A is stored in the database DB of the theft tracking service provider via the Internet line I from the base station A. Thereafter, when a theft report is submitted by the user of the stolen vehicle to the police or the theft tracking service provider, the theft tracking service provider displays the image stored in the database DB from the information terminal T1 in response to a cooperation request from the police. The data is transmitted to the police information terminal T2 via the Internet line I. Incidentally, the reason why the captured image is not directly transmitted from the vehicle 200 to the police is because the privacy protection of the person included in the image is taken into consideration.

  Next, as an operation of the device according to the present embodiment, a specific processing procedure for the image transmission processing to the theft tracking service provider executed by the theft deterrent device 100 when the vehicle 200 is stolen will be described. In this process, the anti-theft device 100 executes the process shown in FIG. 4 when an object present around the vehicle is detected when the vehicle 200 is stopped. In the present embodiment, the following description will be made on the assumption that the main battery 131 is disposed on the front side of the vehicle and the storage chamber is opened and closed by the bonnet B.

  First, the theft deterrent device 100 monitors whether or not the hood B is opened based on the output results of the hood opening / closing sensor 142, the vibration sensor 110, and the like (step S10). When the hood B is opened (step S10 = YES), it is determined whether or not the main battery 131 has been removed from the vehicle 200 (step S11).

  Subsequently, when the main battery 131 is not removed from the vehicle 200 (step S11 = NO), it is determined whether or not the bonnet B is closed (step S12). When the bonnet B is not closed (step S12 = NO), the process returns to step S11, and the main battery 131 is removed from the vehicle 200 or the main battery 131 is mounted on the vehicle 200. Until the bonnet B is closed, the processes of step S11 and step S12 are repeated. On the other hand, when the bonnet B is closed with the main battery 131 mounted on the vehicle 200 (step S12 = YES), it is determined that the bonnet B of the vehicle 200 is opened for maintenance or the like, and the in-vehicle camera 130 The image transmission process shown in FIG. 4 is terminated without taking an image through the screen.

  When the main battery 131 is removed from the vehicle 200 (step S11 = YES), the power supply of the anti-theft device 100 is switched to the backup battery 107 (step S13), and the in-vehicle camera 130 is put on standby for shooting (step S13). S14). Thereafter, whether or not the bonnet B is closed with the main battery 131 removed from the vehicle 200 is determined based on the output results of the bonnet open / close sensor 142, the vibration sensor 110, and the like (step S15). When the bonnet B is not closed (step S15 = NO), the process returns to step S11, and the processes of steps S11 to S15 are repeated until the bonnet B is closed.

  On the other hand, when the hood B is closed (step S15 = YES), it is determined that the hood B of the vehicle 200 has been opened for the purpose of theft, and the photographing operation of the in-vehicle camera 130 is performed to photograph the thief ( Step S16). After that, an image obtained by photographing the thief is wirelessly transmitted to the theft tracking service provider (step S17), and the image transmission process shown in FIG. 4 is terminated.

Next, a processing procedure executed when the database DB of the theft tracking service provider according to the present embodiment provides an image showing the thief of the vehicle 200 to the police will be described.
As shown in FIG. 5, the database DB of the theft tracking service provider waits until an image is received from the vehicle 200 that is the target of the theft (step S20). When the image is received (step S20 = YES), the vehicle ID of the vehicle 200 that is the transmission source of the image and the location information of the shooting point of the image are stored in association with the image (step S21).

  Then, it waits until it receives the theft report of the vehicle 200 used as the transmission source of an image from the police (step S22). When the theft notification is received (step S22 = YES), the image is provided to the police (step S23), and the process shown in FIG. 5 is terminated.

  In the present embodiment, an in-vehicle camera 130 originally provided for driving support of the vehicle 200 is used to photograph the thief of the vehicle 200. For this reason, the culprit for vehicle theft is specified with the minimum necessary configuration, and theft of the vehicle is suppressed.

  Further, as shown by a broken line in FIG. 6, in the original connection configuration in which the encryption communication is directly performed between the immobilizer ECU 132 and the engine ECU 133, when the encryption key information of the immobilizer ECU 132 is leaked due to unauthorized access or the like. The engine ECU 133 may be illegally started using the leaked encryption key information, which may easily allow the vehicle 200 to be stolen.

  In this regard, as shown by a solid line in FIG. 6, in the present embodiment, instead of the above-described original connection configuration, the anti-theft device 100 is connected between the immobilizer ECU 132 and the engine ECU 133 via the wire harness WH. ing. Therefore, even if the information on the encryption key of the immobilizer ECU 132 is leaked, the immobilizer ECU 132 and the engine ECU 133 are blocked from communication when the thief of the vehicle 200 removes the anti-theft device 100 from the vehicle 200. The engine ECU 133 does not start illegally.

As described above, according to the above embodiment, the following effects can be obtained.

In this captured image, the figure immediately after the criminal who tried to steal the vehicle 200 closed the hood B is shown, and it is useful information for identifying the criminal who tried to steal the vehicle 200. Become. Then, such an image is wirelessly transmitted to the database DB of the theft tracking service provider, so that it becomes possible to identify and track the criminal who has attempted to steal the vehicle 200. Note that when the in-vehicle camera 130 takes a picture of a criminal who tries to steal the vehicle 200, the criminal is located outside the vehicle, and the in-vehicle camera 130 is isolated from the criminal. Therefore, even if the criminal notices the presence of the in-vehicle camera 130 when closing the hood B, it is difficult to remove the in-vehicle camera 130 from the vehicle 200 immediately. Therefore, it becomes possible to identify the culprit of vehicle theft with a higher crime deterrent and deter the vehicle 200 from theft.

  (2) The thief of the vehicle 200 is photographed using the in-vehicle camera 130 for driving support of the vehicle 200. For this reason, the culprit for vehicle theft is specified with the minimum necessary configuration, and theft of the vehicle is suppressed.

  (3) When the vehicle 200 that is the subject of the theft captures the thief, the captured image is stored in the database DB of the theft tracking service provider. Therefore, unless the vehicle user submits the theft report to the police or theft tracking service provider, the image stored in the database DB is not provided to the police, so that the privacy of the person included in the image is protected. Be able to.

  (4) The theft deterrent device 100 captures an image through the in-vehicle camera 130 when the proximity sensor 141 detects an object existing around the vehicle while the vehicle speed sensor 140 detects the stop of the vehicle 200. Like to do. Therefore, since monitoring of the surroundings of the vehicle by the antitheft device 100 is selectively performed when the vehicle 200 is likely to be stolen, the processing load on the antitheft device 100 can be suppressed from becoming unnecessarily heavy. .

  (5) The antitheft device 100 is connected between the immobilizer ECU 132 and the engine ECU 133 via the wire harness WH. Therefore, the thief of vehicle 200 is prevented from starting engine ECU 133 illegally.
