[Prior art]

 Conventionally, there are anti-theft devices to prevent the vehicle from being stolen, and there is an automatic door lock device that uses a vehicle speed sensor that can lock the door automatically while the vehicle is running, and they are independent devices. FIG. 4 is a block diagram of an example of such a conventional antitheft device and automatic door locking device.

In the conventional anti-theft device, when the ignition switch 4 connected to the battery 5 of the vehicle is turned off (the engine is stopped), the security control unit 1a of the anti-theft device main body 1 is activated and the security of the security device is increased. The control unit 1a can receive an input of an arming key 1b for instructing activation (called arming) of the security operation and a disarming key 1c for instructing stop (called disarming).

That is, when the arming key 1b is pressed, the security control unit 1a starts the security operation. Therefore, when a thief tries to steal the vehicle and opens the door of the vehicle, the door opening / closing sensor 3a of the sensor unit 3 detects the opening of the door, and when the vehicle tries to move with a tow truck or the like, a vibration sensor of the sensor unit 3 is detected. 3b detects the vibration and inputs a detection signal to the security controller 1a. The security control section 1a outputs a drive signal to the anti-theft means 2 and sounds a warning sound with the siren 2a, and the engine starter is cut off with the starter cut 2b so that the engine cannot be run so that the vehicle cannot run and theft is stolen. To prevent. The security operation is released by pressing the disarming key 1c.

Further, the conventional automatic door lock device detects the vehicle speed when the vehicle reaches a predetermined speed by the vehicle speed sensor 7, inputs the detection signal to the door lock control section 6, and The door lock sensor 8 detects the locked state of the door at that time and inputs a detection signal to the door lock controller 6. The door lock control unit 6 outputs a drive signal to the door lock driving means 9 and locks the door when the vehicle speed detection signal and the door lock detection signal are judged to determine that the door lock is necessary.

[0006]

[Problems to be solved by the device]

 According to such a conventional method, after the ignition switch 4 is turned off and the vehicle is in the off state and the engine is stopped, the arming key 1b is pressed and a predetermined time (a time sufficient for the driver to leave the vehicle) has elapsed, and then the security operation is performed. When the door opening / closing sensor 3a or the vibration sensor 3b of the sensor unit 3 detects an abnormality, the siren 2a and the starter cut 2b are driven based on a command from the security control unit 1a. It operates only when the engine is stopped, and it is extremely dangerous while the engine is running, especially when the vehicle is running, so the security operation was prohibited and the sensor detection signal was not accepted.

If the vehicle is not equipped with an automatic door lock device using the vehicle speed sensor 7 and the door lock sensor 8, there is a danger that the door may be opened while the engine is being driven, especially when the vehicle is running, which is extremely dangerous. The purpose of the present invention is to provide an in-vehicle security device that activates the anti-theft function when the engine is stopped, and can automatically lock the door using the vibration sensor used for the anti-theft function when the engine is running. There is.
