Door Locking Device Having Function of Undoing Immobilizer

The present invention relates to a door control system using wireless communication, and more particularly to a control system that can monitor and control the door of the vehicle.

Conventionally, a mechanical structure based on a key and lock structure has been mainstream as a device for opening and closing a door, and in recent years, a key device, such as a card key type lock device, a fingerprint or an iris, can be used to identify a natural person. Sensor locks are being developed one after another.

However, these devices are inconvenient for users because they must carry a key and operate it mechanically in a lock to open or close a door, or move a card key to a sensor, or move a fingerprint or iris to a position close to the sensor. It was.

On the other hand, as a door control system of the vehicle has been developed a device that allows the driver of the vehicle to open and close the door of the vehicle more conveniently wirelessly, an example of such a device is disclosed in Korean Patent Publication No. 1990-6095 have. This device installs a main control unit inside the vehicle so that only a driver with a remote control whose password is the same as the password stored in the main control unit can open or close the door of the vehicle and turn on / off the starting power. Anyone who does not carry it can detect it and sound an alarm or defeat an intruder.

However, these devices have been troublesome because the driver's door is opened and started only when the driver operates the buttons installed on the remote controller, and malfunctions are frequently caused by the interference of electromagnetic waves generated from various electronic devices around when the product is actually applied. There was a problem.

An example of a device that solves the problem of the device is disclosed in Korean Patent Publication No. 1991-7176. According to this device, the door lock is automatically released when the driver of the vehicle is near the vehicle with the remote control without using the vehicle key, and the door lock is automatically released when the driver moves away from the vehicle with the remote control. It is operated as a burglar alarm after the door is locked.

However, in this technology, when a vehicle and several automatic transmitting remote controllers are manufactured and shipped, a long-wave transceiver for transmitting / receiving long waves in the 100 kHz band and a microwave transceiver for transmitting / receiving microwaves are assigned to a vehicle-specified frequency specified in the Radio Law. Each of them uses the same frequency band, which is used to modulate the long-wave signal and transmit it to the automatic dialing radio remote controller.

Therefore, when accessing the automatic outgoing radio remote controller to TVs, computer monitors, electronic copiers, other home appliances such as three-wavelength fluorescent lamps, and other electric or electronic devices that generate strong radio waves in the 100 kHz or near frequency bands There was a problem that the circuit continued to operate and the internal mercury battery of the card was quickly consumed.

When multiple autonomous radio remote controllers approach a vehicle, all of the autonomous radio remote controllers at long-wave sensitivity distances operate simultaneously, and the microwave transceivers in each autonomous radio remote controller simultaneously transmit unique data. Therefore, the vehicle is prevented from reading the specified unique data by the microwave receiver of the vehicle due to the interference caused by the same frequency.

An apparatus for overcoming the disadvantages of these techniques is disclosed in WO 02/38895 filed by the applicant.

The object of the present invention is to overcome the problems of the prior arts, and to provide a door lock device for a vehicle using a wireless communication in a form different from that of the applicant.

According to another embodiment of the present invention, a signal is communicated by wire between the remote control transmitter and the main device 200. The remote control transmitter may receive power supplied from the vehicle battery via the main device 200 without installing a separate battery.

Referring to the operation of the door / start control device for a vehicle using a portable wireless card according to the present invention.

First, the main device 200 installed in the vehicle periodically transmits the first long wave LF1 including the synchronization signal at a predetermined cycle. In this state, the owner of the portable wireless card 400 has a predetermined distance from his vehicle. When approaching within (for example, within 1m) is generated by the first long-wave wave (LF1) to generate a periodic code in a random (RANDOM) method to load the unique data stored in any one of the plurality of channels to the first ultra-high frequency ( VHF1).

In addition to the unique data included in the first ultra-high frequency (VHF1) transmitted from the portable wireless card 400, a new all-free code is generated every time the reference is made to the period code, the mode code, and the checksum bit. Repetitive transmission is prevented.

The main device 200 receives the first microwave VHF1 transmitted by the portable wireless card 400, detects the unique data, and compares the detected unique data with the unique data stored in the memory (primary ID confirmation). ) If they match each other, they are converted to the second long wave (LF2) including the long wave ID and retransmitted. At this time, the portable radio card 400 compares the long wave ID carried on the second long wave LF2 (confirms the secondary ID). If they match, the second microwave VHF2 including the ID signal and the door release signal is transmitted.

The main device 200 receives the second ultra-high frequency (VHF2) signal transmitted by the portable wireless card 400 and compares it again with the unique data stored in the memory in the main device 200 (confirms the third ID). If they coincide with each other, the vehicle door is released.

Therefore, the main device 200 and the portable wireless card 400 repeatedly compare and confirm the unique data three times by bidirectional communication, thereby improving reliability and eliminating interference by the same frequency.

When the start button of the remote control transmitter 300 is operated while the door is released by the person holding the portable wireless card 400, the start signal is transmitted to the main device 200 as the third microwave VHF3.
