How to control your car's anti-theft device

The present invention relates to a method for controlling an anti-theft device, and more particularly, in the case of an anti-theft device in which the door lock device and the starter are operated in conjunction, a key code for starting the driver with a key when the door lock state is not electrically released. If you start the system by entering the key to the anti-theft control device to start the key immediately for a certain time when the start is turned off.

The anti-theft device installed in the vehicle is a peripheral device installed to prevent others from using the vehicle arbitrarily as a block diagram of the anti-theft device which operates wirelessly in FIG. 1 and controls the start of the door by detecting a door lock condition. Indicated. As shown in FIG. 1, a lock / unlock switch 10 for locking / unlocking a door of a vehicle at a long distance, a transmitter 20 for wirelessly transmitting a value of the lock / unlock switch 10, A receiver 30 for receiving the transmitted signal, an accelerator switch 60 mounted on the accelerator and on / off depending on the state in which the accelerator is operated, an ignition switch IG for supplying power to various devices of the vehicle, Storage unit 50 for storing the code for the start control, and outputs a signal for locking or unlocking the door in accordance with the output of the receiver 30, and whether or not to start up in accordance with the output signal of the input unit 40 A control unit 70 for determining whether to start a non-starting state, an actuator 90 for locking or unlocking a door according to the output of the control unit 70, and a startable state or starting according to the output of the control unit 70 ECU 100 to be disabled and the door It consists of a door lock switch 80 connected to the actuator 90 for locking or unlocking with a key.

Referring to the operation of the anti-theft device made as described above are as follows. When the driver wirelessly operates the lock / unlock switch 10 to lock the door of the vehicle, the transmitter 20 wirelessly transmits the signal, and the received signal is received by the receiver 30 and output to the controller 70. do. The controller 70 operates the actuator 90 according to the received signal to lock the door. In addition, when the lock / unlock switch 10 is operated by unlocking, the control unit 70 operates the actuator 90 to unlock the door. In the anti-theft device operated as described above, while the door is locked, the control unit 70 outputs a non-startable state to the ECU 100 to prevent starting. The above operation is released when the lock / unlock switch 10 is unlocked to be in a startable state. However, when the vehicle is left without locking the door of the vehicle by the lock / unlock switch 10, the door is automatically switched to the locked state after a certain time. However, in this case, if the lock / unlock switch 10 is not carried, the door cannot be started even if the door is opened with the key. In case of this, the key is held, but the door is in the locked state so that it can be started through the accelerator switch 60 so as to enable starting. In order to operate as described above, plug the key into the key cylinder, turn on the ignition switch IG, and operate the accelerator switch 60 to match the passcode, thereby switching to a startable state.

However, when starting the engine as described above and moving the position to receive the after-sales service, if the engine is turned off due to inadequate driving or a mistake in gear shifting, the above operation, that is, the ignition switch IG is turned on In order to enter the passcode by operating the accelerator switch 60 in the switch to the startable state can be started again. However, when the above operation occurs on the road running at high speed or occurs in the middle of the road or railroad, there is a problem that the risk of an accident is contained.

The present invention has been made to solve the above problems, the object of the present invention is to turn off the start when the driver starts the door in the locked state because the driver lost the door lock / unlock switch for a certain time The present invention provides a method of controlling an anti-theft device for a vehicle to maintain a startable state and then switch to a non-startable state.

The present invention for achieving the above object is a method of controlling the anti-theft device to switch to the non-starting state after starting the start for a certain time when the start is turned off when the pass code is entered in the door lock state. .

In the above-described method, if the user enters the passcode in the door lock state and starts the engine in a dangerous situation, the user can start the vehicle immediately through the key for a predetermined time.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. In addition, this embodiment does not limit the scope of the present invention, but is presented by way of example only, and the same reference numerals and names are used by using the same configuration of the conventional apparatus.

2 is a flowchart showing the operation procedure according to the present invention. As shown in FIG. 2, if it is determined that the door is in the locked state and the unlocked state is terminated, and in the locked state, the process returns to the step of determining the on state of the ignition switch IG and the ignition switch IG. If it is not in the on state by determining whether the state is ON and the ignition switch (IG) is turned on, the step of returning to the step of determining the operating state of the engine (S20) and if the engine is operating If the engine is not in operation and returns to the startable state, the process returns to the step of determining whether a pass code has been entered (S30). If the pass code has not been entered, the process returns to the step of determining whether the door is locked and the pass code is returned. If it is input, the process returns to the step of judging whether the passcodes match (S40), and if the passcode does not match the stored passcode, the operation is made impossible. And returning to the system and returning to the startable state when the passcodes match (S50), determining the operating state of the engine in the startable state (S60), and determining whether the engine is in operation. When the engine is in operation, the engine is returned to the startable state. If the engine is not operated, the step is returned to the step of delaying about 10 to 20 seconds (S70), and the delay is about 10 to 20 seconds and then returned to the non-starting state. Step S80, and the step (S90) is returned to the step of confirming the door lock state in the non-startable state.

Referring to the operation of the present embodiment made as described above are as follows. First of all, if the door is in the unlocked state by checking whether the door is in the locked state or the unlocked state, the method is terminated because the driver is unlocked by the lock / unlock switch 10 of the anti-theft device (S10). (S100). However, in the locked state, the driver checks whether the ignition switch IG is in the IG1 state in order to confirm that the driver intends to start the vehicle (S20). At this time, since the driver does not try to start unless the IG1 state (S20) (S100). However, if the ignition switch (IG) is turned on to start the engine to check the operating state (S30). This step is returned to the startable state in order to maintain the startable state without inputting a pass code in case of starting the door in preparation for the door being locked in the state of starting (S30) (S60). However, if the start is not applied, it is determined whether the passcode is input while maintaining the state for inputting the passcode (S40). 3 illustrates a case in which the pass code is '12314'. As shown in FIG. 3, the accelerator code is set by pressing and releasing the accelerator pedal (S40). Then, if the inputted passcode matches the stored passcode, and compares with the determined passcode, it is made possible to start up with the key (S50) (S60). However, if it does not match, it is possible to maintain a non-starting state (S50) (S90). In this way, in order to start the engine after the start in order to receive the after-service to check the operating state of the engine (S70). At this time, if the engine is in operation, the engine can be started continuously. If the engine is stopped, the engine can be started with the key for about 10 to 20 seconds and then switched to the non-startable state (S80) (S90). . When it becomes impossible to start (S90), the lock state of the door is determined (S10), the on state of the ignition switch is determined (S20), the engine is stopped (S30), and the pass code is input again (S40). If it matches (S50), it becomes a startable state (S60). This will allow you to start.

As described above, the present invention enters the passcode and starts the vehicle, and when the engine is turned off during the movement, it is switched to the non-startable state with a certain amount of time, for example, in an emergency situation such as a railroad or a high-speed driving lane. The advantage is that you can start the vehicle to cope with the danger.
