The gyro sensor 106 is composed of a vibration sensor, a 3D sensor, etc., detects an angular velocity due to a change in the direction of the vehicle, generates a signal corresponding to the angular velocity, and outputs the signal to the control unit 102. This angular velocity information is
A general method is to carry out information transmission by fluctuations in the operating voltage of the gyro sensor 106 in a dynamic range. The power supply control unit 111 uses the gyro sensor 106.
To the analog reference voltage input terminal of the analog-digital converter included in the control unit 102. The gyro sensor 106 outputs the angular velocity information when confirming the angular velocity fluctuation in this power supply voltage range as a voltage value. For example, when a voltage of 5 [V] is applied to the gyro sensor 106, the gyro sensor 106 outputs a voltage of about 2.5 [V] in a non-rotating state. When it is detected that it has rotated further to the right, it is possible to change from 2.5 [V] to 5.
The voltage between 0 [V] is output, and when the rotation to the left is detected, the voltage between 2.5 [V] and 0 [V] is output. The control unit 102 inputs the level to which the reference voltage 5 [V] has changed,
Changes in angular velocity can be detected. Gyro sensor 10
The voltage output from 6 fluctuates depending on the magnitude of the changed angle, or whether it changes abruptly or gently. Therefore, by detecting the voltage level and the time required until it fluctuates, detection of these Is possible. Furthermore, by detecting the abnormality of the gyro sensor 106,
The reliability of the anti-theft device 1 can be improved. The control unit 102 monitors the output voltage from the gyro sensor 106, determines that there is an abnormality when the voltage exceeds a certain level or continues at a voltage less than the certain level, and performs an abnormality warning process and a theft warning. Further, by executing the theft report processing, the abnormal state of the antitheft apparatus 1 is transmitted, or the vibration generated when the antitheft apparatus 1 is detached is detected, and the warning processing is executed. It becomes possible.

The vehicle speed pulse receiver 107 receives a pulse signal indicating the number of rotations of a wheel from a vehicle speed sensor mounted on a wheel, reduces the voltage of the pulse signal, processes the pulse signal for shaping, corrects, or a number. A process of converting the vehicle speed signal to a vehicle speed signal is performed and a process of outputting the vehicle speed signal to the control unit 102 is performed. The vehicle speed sensor is usually provided in a vehicle equipped with an ECU (electronic control unit) in order to obtain vehicle speed information necessary for controlling the engine of the vehicle.

The vehicle speed signal is acquired by and the current speed is grasped. Note that it is possible to use these pieces of information to grasp the absolute position information using GPS information, and to generate accurate position information that is corrected by displacement of the relative position using angular velocity information and vehicle speed information. By transferring the obtained location information together with the information output to the theft monitoring center when a theft is detected, the theft monitoring center can grasp the location of the stolen vehicle and can be used for theft tracking. it can.

Further, the control unit 102 controls the immobilizer 5
While obtaining collation information from the vehicle's electronic key from
The rotational position of the key cylinder 6 is acquired. If the immobilizer 5 is not able to check with the electronic key, or if the key cylinder 6 is not in the accessory power supply state or the ignition power supply state, that is, in the off state, it is determined that the owner of the vehicle is not in the vehicle. And continue the theft monitoring process. In determining the process of performing or stopping this theft monitoring, any one of the information from the immobilizer 5 and the information from the key cylinder 6, or both information, and information from another sensor are used. Good.

During the theft monitoring process, if the information from the GPS receiver 105 moves a certain distance or more, or if the signal from the gyro sensor 106 changes a certain angular velocity or more, or if the information from the vehicle speed pulse receiver 107 determines a certain value. When the speed or more is measured, it is determined that the theft has occurred, and the process goes to the theft reporting process. The condition for determining the theft may be monitoring by all of GPS information, angular velocity information, vehicle speed information, monitoring by any one or more information, and further monitoring by another condition. Other conditions include position information from the GPS receiver 105, angular velocity information from the gyro sensor 106, and vehicle speed pulse receiver 107.
It can also be realized by combining vehicle speed information from. For example, when it is recognized that the vehicle is not moving based on the information from the vehicle speed pulse receiver 107, the GPS
When the position information from the receiver 105 moves, or when it is recognized that the vehicle is not moving based on the information from the vehicle speed pulse receiver 107, the gyro sensor 106
When the angular velocity changes according to the angular velocity information from, it is possible to detect the theft more reliably by determining the theft due to the transportation of the vehicle itself.

The control unit 102, which has determined that the device is stolen, outputs a control signal for issuing a warning sound to the warning sound generating device 103. The warning sound generator 103 performs a sounding process of the buzzer 2. The sounding process may output not only a warning sound such as a buzzer but also a warning using a siren, a voice prompting theft prevention by a voice reproduction process, and the like. In addition, the control unit 10
2 outputs a control signal for performing warning illumination to the illumination control unit 104. The lighting control unit 104 performs lighting control and blinking control of the LED 3. For the lighting process, not only the LED 3 but also flash lighting such as a flash may be used.
In addition, a character or the like that prompts theft prevention using a liquid crystal screen may be displayed.

The control unit 102 also performs a process of recording information such as the date and time of the theft and a condition (trigger) for detecting the theft in the storage unit 112 and a process of acquiring the telephone number of the theft monitoring center. The control unit 102 uses the mobile phone wireless device 101 to perform a call origination process for the phone number of the theft monitoring center. When the theft monitoring center receives an incoming call and shifts to the communication state, the control unit 102
It recognizes the incoming call and transmits information such as the date and time of the theft recorded in the storage unit 112 and the conditions for detecting the theft. The mobile phone wireless device 101 uses the mobile phone antenna 8 to perform a wireless communication process with a base station of a communication carrier to make a phone call,
Perform data communication processing after incoming.

In the communication between the anti-theft device 1 and the theft monitoring center, is reliable information transmission performed by repeating the output of the calling signal from the anti-theft device 1 and the acquisition of the response signal to the calling signal. Can be grasped. When the response signal cannot be acquired in response to the information transmission from the anti-theft device 1, a re-output process is performed, and this process is repeated until the response signal can be acquired. If the response signal cannot be acquired for a certain number of times of output processing, the next signal is output. Alternatively, the line is disconnected and the call is made again. By reliably continuing the process until the transmission process is completed, reliable information can be transmitted.

By recording the processing history in the storage unit 112, it becomes possible to use it for the theft history analysis processing. The data to be recorded is the case where the theft report process was completed normally, the transmission process could not be performed normally, the state in which the transmission was interrupted, the reason for the interruption, the number of retries. By recording the date and time of each history in detail, further information analysis becomes possible.

Also, the external device connection interface 11
An external device such as a portable personal computer can be connected to 0. If you connect a non-illustrated external device and obtain a signal requesting a theft history signal from the external device,
The control unit 102 extracts the theft history information and the like from the storage unit 112, and outputs the theft history information to an external device via the external device connection interface 110. The external device displays the history information on the screen so that the date and time when the theft occurred,
It is possible to understand the factors that detected the theft. The communication between the externally connected device and the anti-theft device 1 can be realized by using a communication technology such as 232C communication or USB which is standardly equipped in the personal computer.
