To do this, the card transmitter holder opens the car door (ie, the driver's door) with the battery of the card transmitter removed, inserts the ignition key into the ignition holder within a predetermined time (e.g., 10 seconds), 'ACC') and the second stage (i.e., 'ON') is a round-trip operation a predetermined number of times (for example, five times). Then, when the battery is inserted into the card transmitter within a predetermined time (for example, 5 seconds), the ID embedded in the card transmitter is registered. A plurality of card transmitters of the present invention can be implemented, and each card transmitter can have the same ID or different IDs. For example, when two card transmitters are used, after ID registration of one card transmitter, the ID is registered when the battery is inserted into another card transmitter within a predetermined time (for example, 5 seconds). Similarly, in order to delete the registered ID and pause the function of the card transmitter, the same method as in the ID registration is performed, but the battery must be extracted from the card transmitter. The method of registering and deleting the ID of the card transmitter is not limited to the above-described method, and the ID can be registered by various other methods (for example, by reciprocating the door switch a predetermined number of times).

The card transmitter periodically transmits the radio frequency corresponding to its ID to the outside through the radio transmitter at regular intervals (for example, every 2 seconds), and the radio receiver of the main box receives the radio frequency. Apply to CPU. In this case, the user may set a desired operation distance by using the communication distance controller. Therefore, the transmitter_CPU controls to transmit the radio signal according to the operation distance set by the communication distance controller. However, the radio frequency transmitted from the card transmitter located within a certain range (for example, within 2 to 3m) at the time of ID registration is applied to the main box_CPU, but the reciprocating number of times between the first and second stages of the ignition holder described above If no motion is detected, the radio frequency is ignored. On the other hand, since the ID data applied after a predetermined operation for ID registration is a regular ID that has undergone a correct ID registration process, the corresponding ID data is stored in the memory unit. Therefore, the main box is set to be operated only by the registered ID. In addition, in order to register a new ID, if the above-described ID registration process is performed again, a desired ID can be newly registered. A plurality of card transmitters of the present invention can be implemented, and each card transmitter can have the same ID or different IDs. For example, when two card transmitters are used, after ID registration of one card transmitter, the ID is registered when the battery is inserted into another card transmitter within a predetermined time (for example, 5 seconds). Similarly, in order to delete the registered ID and pause the function of the card transmitter, the same method as the ID registration is performed, but the battery must be extracted from the card transmitter. In implementing the pause function of the card transmitter, the function of the card transmitter can be paused by the above-described operation, but it is provided with a specific switch at one end of the card transmitter and the radio is transmitted from the card transmitter by the operation of this specific switch. It can be implemented to block the signal.

When the holder of the card transmitter enters a predetermined range (for example, within 2 to 3 m), the main box receives an ID transmitted from the card transmitter, and first determines whether the ID is a registered ID. If the corresponding ID is not a registered ID, the corresponding signal is ignored. If the ID is a registered ID, the door unlock signal is sent to the control buffer to control the door lock motor to be driven. When the door unlock signal is applied, the door lock motor drives the door switch to operate the vehicle door in an open state. At the same time, the main box sends a driving signal and an alarm signal to the control buffer to notify the outside that the vehicle door is in the open state. That is, by driving the left / right direction light (e.g. blinking twice) and generating an alarm sound (e.g. two beeps), the card transmitter holder can easily recognize that the car door is in the open state. .

Conversely, if the holder of a particular card transmitter deviates from a certain range (e.g., within 2 to 3 m) (if no radio frequency is detected from the specific card transmitter), the main box assumes that the card transmitter holder is out of the vehicle and into the control buffer. The door lock signal is sent to control the door lock motor to be driven. When the door lock signal is applied, the door lock motor drives the door latch to operate the vehicle door to be locked. At the same time, the main box sends a turn signal driving signal and an alarm generation signal to the control buffer to notify the outside that the vehicle door is locked. That is, by driving the left / right direction light (e.g., blinking once) and generating an alarm sound (e.g., one alarm), the card transmitter holder can easily recognize that the vehicle door is locked. .

In addition, when the driver sits in the driver's seat with the card transmitter, even if the door switch is locked manually or automatically, the main box transmits the door unlock signal because the registered ID is continuously received from the card transmitter. Therefore, when the card transmitter holder is in the vehicle, the door unlock state continues. To solve this problem, when the IG detection signal is applied from the control buffer, the main box ignores the signal even if a registered ID of the card transmitter is received thereafter, thereby preventing the door switch from being locked manually or automatically during operation. In this case, do not drive the door switch in the open state to maintain the current state. In addition, when the driver is out of a certain range while the car door is open, the driver may maintain the current state without driving the car door in the locked state even if the registered ID is not received. The IG detection signal is detected by an ignition detection unit connected to the ignition holder, and the IG detection signal is detected when the driver rotates the key to 'ON' or 'ACC' state with the key inserted into the ignition holder.

If the taillight auto power off function is added, the tail light is automatically turned off when the driver leaves the vehicle without inadvertently turning off the tail light. In addition, if the car door is opened by another method (e.g., ignition key, etc.) without using the card transmitter, the alarm siren sounds for a predetermined time (e.g., 30 seconds), and the alarm is released (e.g., the ignition key is released). Inserted into the ignition holder and placed in the first or second stage, etc.) is implemented to ring again.

That is, the mobile terminal 600 performs the function of the card transmitter of the first embodiment. In this case, in order to perform the door opening / closing function by the unique ID of the wireless transmitter 650, an ID registration operation should be performed like the card transmitter 110. The unique ID registration is possible by a user holding the mobile terminal 600 within a predetermined distance (for example, 2 to 3) in the vehicle by pressing a specific switch. For example, after long pressing a key button marked with '*' among a plurality of input buttons provided in the mobile terminal for a predetermined time (for example, 3 seconds), the key button marked with '#' is repeated twice. ID can be entered by pressing the button. In addition, even when a new ID is to be registered, it may be registered by performing the above-described specific operation. The ID registration start signal by the key button of the mobile terminal is a start signal for registering the corresponding ID in the main box. In order to register the corresponding ID in the main box, a specific operation (starting key is applied to the ignition holder in the same manner as in the first embodiment). After the insertion, an operation of reciprocating a predetermined number of times (eg, five times) between the first stage (that is, 'ACC') and the second stage (that is, 'ON') should be performed.

After performing the ID registration procedure of the mobile terminal, when the user having the mobile terminal transmits an IR signal by pressing a specific button within a certain distance (for example, 3m), the wireless receiver 132 of the main box 130 sends the corresponding signal. Receives the signal to the main box_CPU 133, the main box_CPU 133 determines whether the registered ID signal, and if the registered ID signal to drive the door lock motor 140 to maintain the car door in the unlocked state Let's do it. In addition, when a user having a mobile terminal sends an IR signal again by pressing a specific button within a certain distance (for example, 3m), the wireless receiver 132 of the main box 130 receives the corresponding signal and receives the main box_CPU ( 133, and the main box_CPU 133 determines whether the registered ID signal is a registered ID signal and drives the door lock motor 140 to maintain the vehicle door in a locked state.

In addition, as in the first embodiment, the operating distance of the mobile terminal can be freely changed using a specific button (for example, a moving key), and the ID transmission function of the mobile terminal can be paused using a specific button (for example, a delete key). The vehicle door opening and closing operation other than the above-described functions is the same as in the first embodiment, and thus description thereof is omitted.
