Description
본 발명은 차량의 도난 방지시스템에 관한 것으로, 보다 상세하게는 차량 키를 탈거하면 브레이크 시스템이 작동되지 않도록 된 차량의 도난 방지시스템에 관한 것이다.The present invention relates to an anti-theft system of a vehicle, and more particularly, to an anti-theft system of a vehicle such that the brake system is not operated when the vehicle key is removed.
일반적으로 차량에는 에탁스(Electronic Time & Alarm Control System)이라는 컴퓨터에 의해 차량의 시간과 경보기능 및 이그니션 키 회수 즉, 키를 꽂고 도어를 잠글 수 없도록 하는 등의 기능을 제어하도록 되어 있는데, 현재는 이와 같은 에탁스를 이용하여 차량의 도난을 방지하는 기능이 부가되어 진다.In general, the vehicle is controlled by a computer called the Electronic Time & Alarm Control System to control the vehicle's time and alarm functions and the ignition key recovery, that is, the key cannot be inserted and the door is locked. The function of preventing theft of the vehicle by using such an etax is added.
이와 같이, 상기 에탁스를 이용한 차량 도난 방지는 차량의 아밍(Arming;도난현상)상태를 작동시켜 차량의 이상징후가 발생되면 즉, 비정상적인 방법으로 도어를 연 다거나 시동을 거는 것과 같은 조작 상태가 상기 에탁스에서 감지되면 차량에 설치된 알람 경보기나 혼(Horn)을 작동시켜 경고하는 제어 방식을 사용하는 것이 널리 이용되고 있다.As described above, the vehicle anti-theft prevention using the etax operates an arming state of the vehicle, and when an abnormal symptom of the vehicle occurs, that is, an operation state such as opening or starting the door in an abnormal manner may occur. It is widely used to use an alarm alarm installed in a vehicle or a control method that activates and alerts a horn when detected by Etax.
또한, 이와 같은 방식에서 더 나아가 암호코드를 내장한 이그니션키를 이용해 도어나 엔진 시동을 거는 경우, 상기 키의 암호와 ECU(Engine Control Unit)간에 인증 절차를 통하지 않을 경우 작동을 원천적으로 차단하여 도난을 방지하는 방식도 사용되고 있는 추세이다.In addition, in the case of starting the door or engine using the ignition key with a built-in encryption code, if the authentication procedure is not performed between the key and the ECU (Engine Control Unit), theft is blocked by the source. The way to prevent this is also being used.
그러나, 이와 같은 도난 장치들은 차량의 도난 방지에 어느 정도 기여를 하고 있는 실정이지만 차량의 도난 목적으로 무단 침입할 때 경보음등을 듣지 못하였을 경우, 침입자가 비정상적인 방법으로 시동을 걸어 차량을 움직일 수 있어 완벽한 차량 도난 대책이 되지 못하는 한계가 있게 된다.However, these theft devices contribute to the prevention of theft of the vehicle to some extent, but if the intruder does not hear the alarm sound when trespassing for the purpose of theft, the intruder can start the vehicle in an abnormal way and move the vehicle. There is a limit that cannot be a complete vehicle theft protection.
이에 따라, 최근에는 인공위성을 이용하여 차량의 도난 위치를 추적하거나 인식되지 않은 운전자가 차량을 운행할 경우 차량에서 기지국등으로 신호를 전송해 강제적으로 차량의 엔진을 멈추거나 차량 주행에 필요한 장치를 강제로 작동시키지 않는 제어 방식들이 개발되고 있는 실정이다.Accordingly, in recent years, a satellite is used to track a stolen location of a vehicle or when an unrecognized driver drives the vehicle, transmits a signal from the vehicle to a base station, forcibly stopping the engine of the vehicle or forcing a device necessary for driving the vehicle. Control schemes that do not operate with the current situation are being developed.
그러나, 이와 같이 최근에 개발되고 있는 방법은 통신을 주고받을 수 있는인공위성과 기지국등과 같은 기간시설이 반드시 요구되어 실현하는데 많은 비용과 기간이 소요되는 한계가 있어 이러한, 기간시설이 없이도 차량의 도난을 보다 완벽하게 방지할 수 있는 시스템의 개발이 절실히 요구되고 있는 실정이다.However, such a recently developed method has a limitation in that it requires a lot of cost and time to realize the necessary infrastructures such as satellites and base stations that can communicate with each other. There is an urgent need for the development of a system that can prevent the error more completely.
이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 엔진의 시동을 위한 시동키를 탈거하면 브레이크시스템의 마스터실린더의 유압통로를 차단시켜 차량의 이동을 불가능하게 하여 도난을 방지함에 그 목적이 있다.Therefore, the present invention has been invented in view of the above, and when removing the ignition key for starting the engine, the object is to prevent theft by blocking the hydraulic passage of the master cylinder of the brake system to make the vehicle impossible to move. have.
상기와 같은 목적을 달성하기 위한 본 발명은, 브레이크페달의 조작력을 유압을 통해 배력시켜 제동 유압을 발생시키는 마스터실린더와, 브레이크의 조작과 함께 시동키가 이그니션스위치에서 탈거되면 마스터실린더의 유압통로를 차단시켜 차륜에 구비된 휠실린더의 유압복귀를 차단하는 차단수단으로 이루어진 것을 특징으로 한다.The present invention for achieving the above object, the hydraulic power of the master cylinder to remove the hydraulic cylinder of the master pedal to generate the braking hydraulic pressure by applying the operating force of the brake pedal, and the brake is removed from the ignition switch with the operation of the brake It characterized in that the blocking means for blocking the hydraulic return of the wheel cylinder provided on the wheel by blocking.

여기서, 상기 차단수단은 마스터실린더(M)의 유압통로(G)에 내장되어 오일의 흐름을 감지하는 압력센서(1)와, 이 압력센서(1)의 신호에 따라 배터리의 전원을 통전시킴과 더불어 이그니션스위치(IG)의 오프(Off)위치 시 배터리의 전원이 통전되는 릴레이(5), 상기 마스터실린더(M)의 유압통로(G)사이의 보조챔버(CH')에 내장되어 릴레이(5)의 연결에 따라 통전된 배터리의 전원에 의해 여기되는 전자석(2), 이 전자석(2)의 작동에 따라 반발력으로 유압통로(G)에 수직하게 형성된 차단통로(g)로 삽입되어 오일의 흐름을 차단하는 한 쌍의 차단피스톤(3) 및 이 피스톤(3)에 의해 압축된 후 전자석(2)의 오프 시 복원력을 발생해 피스톤(3)을 원위치로 복귀시키는 스프링(4)으로 이루어진다.Here, the blocking means is built in the hydraulic passage (G) of the master cylinder (M) and the pressure sensor (1) for detecting the flow of oil, and energizing the battery according to the signal of the pressure sensor (1) and In addition, the relay 5 is built in the auxiliary chamber CH 'between the relay 5 and the hydraulic passage G of the master cylinder M when the ignition switch IG is turned off. The flow of oil is inserted into the electromagnet (2) excited by the power of the battery energized by the connection of), the blocking passage (g) formed perpendicular to the hydraulic passage (G) with a repulsion force by the operation of the electromagnet (2) It consists of a pair of blocking piston (3) for blocking the piston (3) and a spring (4) for compressing by the piston (3) to generate a restoring force when the electromagnet (2) is off to return the piston (3) to its original position.

In accordance with the signal of the pressure sensor 1 for detecting the flow of oil is made of a second relay (5b) for energizing the power of the battery to the electromagnet (2).
이하 본 발명의 작동을 첨부된 도면을 참조로 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.
운전자가 차량을 정지시키기 위해 브레이크페달을 조작하게 되면 부스터의 진공압을 이용해 부스터로드(B)가 마스터실린더(M)를 가압(F)하게 되고 이에 따라, 상기 마스터실린더(M)가 실린더(C)에 형성된 챔버(CH)에 내장된 피스톤(P)을 이동시켜 오일리저버(R)내 오일을 가압하여 유압통로(G)를 통해 차륜에 장착된 휠실린더로 공급해 제동을 하게된다.When the driver manipulates the brake pedal to stop the vehicle, the booster rod B presses the master cylinder M using the vacuum pressure of the booster, whereby the master cylinder M is the cylinder C. The piston (P) built in the chamber (CH) formed in the) is moved to pressurize the oil in the oil reservoir (R) and supplied to the wheel cylinder mounted on the wheel through the hydraulic passage (G) to brake.
이때, 상기 마스터실린더(M)와 이그니션스위치(IG)사이에 구비된 릴레이(5)의 제2릴레이(5b)에는 상기 마스터실린더(M)의 유압통로(G)를 통해 휠실린더로 공급되는 오일의 흐름을 감지하도록 유압통로(G)에 구비된 압력센서(1)가 전기신호를 공급하게 되지만 만약, 상기 이그니션스위치(IG)에서 키를 탈거시키지 않게 되면 이 이그니션스위치(IG)를 매개로 배터리의 전원이 통전되는 제1릴레이(5a)에는 전원이 통전되지 않아 상기 마스터실린더(M)의 보조챔버(CH')에 내장된 전자석(2)이 작동되지 않아 마스터실린더(M)의 유압통로(G)를 차단하지 않게 된다.At this time, the oil supplied to the wheel cylinder through the hydraulic passage (G) of the master cylinder (M) to the second relay (5b) of the relay (5) provided between the master cylinder (M) and the ignition switch (IG). Pressure sensor 1 provided in the hydraulic passage (G) to detect the flow of the electric signal is supplied, but if the key is not removed from the ignition switch (IG) via the ignition switch (IG) as a medium The power supply is not energized in the first relay 5a through which the power is supplied, so that the electromagnet 2 built in the auxiliary chamber CH 'of the master cylinder M is not operated, and thus the hydraulic passage of the master cylinder M ( G) will not be blocked.
한편, 운전자가 상기 이그니션스위치(IG)에서 키를 탈거시키게 되면 즉, 키 오프하게 되면 이그니션스위치(IG)를 매개로 배터리의 전원이제1릴레이(5a)로 통전되면서 상기 마스터실린더(M)의 유압통로(G)에 구비된 압력센서(1)를 통해 전기신호가 공급되는 제2릴레이(5b)로 배터리의 전원이 통전 되어진다.On the other hand, when the driver removes the key from the ignition switch IG, that is, when the key is off, the power of the battery is energized to the first relay 5a via the ignition switch IG and the hydraulic pressure of the master cylinder M is obtained. The power of the battery is energized to the second relay 5b through which the electrical signal is supplied through the pressure sensor 1 provided in the passage G.
이에 따라, 상기 제2릴레이(5b)에 연결된 전자석(2)이 여기되어 양 쪽으로 구비된 한 쌍의 차단피스톤(3)을 반발력으로 밀어 유압통로(G)에 수직하게 형성된 차단통로(g)로 삽입되면서 오일의 흐름을 차단해 브레이크페달의 조작력을 해제하더라도 휠실린더로 공급된 오일을 복귀시킬 수 없어 차륜의 제동 상태가 해제되지 않고 유지되어지게 된다.Accordingly, the electromagnet 2 connected to the second relay 5b is excited to push the pair of blocking pistons 3 provided at both sides with a repulsive force to the blocking passage g formed perpendicular to the hydraulic passage G. Even if the oil flow is blocked while the brake pedal is released to release the operating force of the brake pedal, the oil supplied to the wheel cylinder cannot be returned, and the braking state of the wheel is maintained without being released.
한편, 만약 운전자가 시동키를 이그니션스위치(IG)에 꽂아 온(On)시키게 되면 배터리의 전원이 통전된 릴레이(5)의 제1릴레이(5a)가 오프되면서 배터리의 전원이 차단되고 이에 따라, 상기 제1릴레이(5a)에 연결된 제2릴레이(5b)의 전원도차단되면서 전자석(2)을 오프시켜 압축되었던 스프링(4)의 복원력이 차단피스톤(3)을 초기 위치로 복귀시켜 차단통로(g)를 개발해 유압통로(G)를 통해 휠실린더로 공급된 오일을 복귀시켜 차륜의 제동 상태를 해제시키게 된다.On the other hand, if the driver plugs the ignition key into the ignition switch IG and turns it on, the first relay 5a of the relay 5, which is powered by the battery, is turned off and the battery power is cut off. As the power of the second relay 5b connected to the first relay 5a is also turned off, the restoring force of the spring 4 compressed by turning off the electromagnet 2 returns the blocking piston 3 to its initial position, g) is developed to release the oil supplied to the wheel cylinder through the hydraulic passage (G) to release the brake state of the wheel.
이상 설명한 바와 같이 본 발명에 의하면, 브레이크페달의 조작력을 유압을 통해 배력시켜 제동 유압을 발생시키는 마스터실린더가 조작되면서 시동키가 탈거되면 휠실린더의 유압복귀를 차단시켜 시동키를 이용해 이그니션키를 조작하지 않게 되면 브레이크 제동력을 해제하지 않아 차량의 이동을 불가능하게 되어 도난을 방지 할 수 있는 효과가 있게 된다.As described above, according to the present invention, when the ignition key is removed while operating the master cylinder that generates the braking hydraulic pressure by increasing the operating force of the brake pedal through the hydraulic pressure, the hydraulic cylinder of the wheel cylinder is shut off to operate the ignition key using the ignition key. If not, the brake braking force is not released and the vehicle cannot be moved, thereby preventing theft.
