본 발명은 차량의 도난 방지 장치에 관한 것으로, 더욱 상세하게는 차량의 시동시 시동키로부터 설정된 코드화 신호가 인가되었을 경우에만 시동이 가능하도 록 하여 차량의 도난을 방지하도록 차체인증모듈을 이용한 이모빌라이저 강화시스템 및 그 방법에 관한 것이다.The present invention relates to a vehicle anti-theft device, and more particularly, to enhance the immobilizer using the vehicle body authentication module so that the vehicle can be started only when a coded signal set from the start key is applied when the vehicle starts. A system and method thereof are provided.

일반적으로 차량의 핸들에는 차량의 키홀더로부터 키를 뺀 상태에서는 핸들이 자동으로 잠겨져 핸들이 돌아가지 않도록 함으로써 차량의 도난을 방지하도록 하는 이모빌라이저가 장착되어 있다.In general, the steering wheel of the vehicle is equipped with an immobilizer to prevent theft of the vehicle by preventing the steering wheel to rotate automatically when the key is removed from the key holder of the vehicle.

상기 이모빌라이저가 장착된 차량은 차량의 시동시 시동키로부터 암호화코드가 인가될 때에만 시동이 되도록 하여 차량의 도난을 방지하는 것으로 종래의 이모빌라이저 시스템을 도 1을 참조하여 설명하면 다음과 같다.The vehicle equipped with the immobilizer prevents theft of the vehicle by starting only when an encryption code is applied from the ignition key at the start of the vehicle. The conventional immobilizer system will be described with reference to FIG. 1.

도시된 바와 같이 차실내에 구비되는 시동키 트랜스폰더(1a) 및 이모빌라이저(3)와, 엔진룸 내에 장착되는 엔진 ECU(4)를 포함하여 구성된다.As shown in the figure, a starter key transponder 1a and an immobilizer 3 provided in the vehicle compartment and an engine ECU 4 mounted in the engine compartment are included.

시동키 트랜스폰더(1a)는 시동키(1)에 내장되고, 초기 자동차 EOL(End Of Line)에서 설정된 시동키 ID(KEY_ID) 및 시동키 암호화코드(KEY_ENCRYPT)를 저장하고, 시동시 엔진 ECU(4)로 시동키 ID와 시동키 암호화코드를 송신하여 자차인지를 확인할 수 있도록 한다.The ignition key transponder 1a is embedded in the ignition key 1, and stores the ignition key ID KEY_ID and ignition key encryption code KEY_ENCRYPT set in the initial vehicle EOL (End Of Line). 4) send the ignition key ID and ignition key encryption code to check whether it is own vehicle.

이모빌라이저(Immobilizer)(3)는 시동키(1) 내부에 내장된 시동키 트랜스폰더(1a)와 엔진 ECU(4) 사이에 정보 교환을 할 수 있도록 통신을 가능하게 해준다.An immobilizer 3 enables communication between the starter key transponder 1a built in the starter key 1 and the engine ECU 4 to exchange information.

엔진 ECU(4)는 초기 자동차 EOL에서 설정된 시동키 ID(KEY_ID) 및 시동키 암호화코드(KEY_ENCRYPT)를 저장하고 있다가, 시동시 시동키 트랜스폰더(1a)에서 송신한 시동키 ID 및 시동키 암호화코드와 비교하여 일치하면 차량의 시동을 가능하게 하고 일치하지 않으면 엔진 시동을 금지한다.The engine ECU 4 stores the ignition key ID KEY_ID and ignition key encryption code KEY_ENCRYPT set in the initial vehicle EOL, and then transmits the ignition key ID and ignition key encryption transmitted from the ignition key transponder 1a at startup. If a match is made with the code, the vehicle is allowed to start, and if it does not match, the engine is prohibited.

상기한 구성에서 운전자가 차량 엔진을 시동하기 위하여 시동키(1)를 시동키 홀더에 삽입하고 시동키를 온(ON) 하면, 엔진 ECU(4)는 시동키 인증을 위한 루틴을 수행한다.In the above configuration, when the driver inserts the ignition key 1 into the ignition key holder and turns the ignition key ON to start the vehicle engine, the engine ECU 4 performs a routine for ignition key authentication.

즉, 시동키(1)가 온되면 안테나 코일(2)에 의해 시동키 트랜스폰더(1a)에 전원이 인가되어 작동한다.That is, when the starter key 1 is turned on, power is applied to the starter key transponder 1a by the antenna coil 2 to operate.

The signal is applied to enable the vehicle to start.

이때, 수신된 시동키 ID 및 시동키 암호화코드가 일치하지 않을 경우에는 엔진 시동을 금지하여 제3자에 의한 차량의 도난을 방지한다.At this time, when the received start key ID and the start key encryption code do not match, the engine is prohibited from being started to prevent theft of the vehicle by a third party.

상기한 구성에서 운전자가 차량 엔진을 시동하기 위하여 시동키(10)를 시동키 홀더에 삽입하면(S402), 엔진 ECU(40)에서 차체인증모듈(50)에 전원을 공급하여 차체인증모듈(50)을 웨이크업(Wake-up)시킨다(S404).In the above configuration, when the driver inserts the ignition key 10 into the ignition key holder in order to start the vehicle engine (S402), the engine ECU 40 supplies power to the vehicle body authentication module 50 to supply the vehicle body authentication module 50. ) And wake-up (S404).

이후 엔진 ECU(40)는 차체인증모듈(50)과의 정보교환과 비교로 1차 차체 인증 루틴을 수행한다.Thereafter, the engine ECU 40 performs the primary vehicle body authentication routine in comparison with information exchange with the vehicle body authentication module 50.

먼저, 엔진 ECU(40)는 난수를 생성(ENG_RAND = Frand())하여 생성된 난수(ENG_RAND)를 차체인증모듈(50)에 전송한다(S406).First, the engine ECU 40 transmits the random number ENG_RAND generated by generating a random number (ENG_RAND = Frand ()) to the vehicle body authentication module 50 (S406).

차체인증모듈(50)은 상기 엔진 ECU(40)로부터 수신한 난수(ENG_RAND)와 초기 자동차 EOL에서 설정된 차체 암호화코드(BODY_ENCRYPT)를 변수로 이용하여 인증용 난수를 생성(AUTH_RAND = AUTH_Frand(ENG_RAND, BODY_ENCRYPT)하고, 생성된 인증용 난수(AUTH_RAND)를 엔진 ECU(40)에 전송한다(S408).The vehicle body authentication module 50 generates a random number for authentication using the random number ENG_RAND received from the engine ECU 40 and the body encryption code BODY_ENCRYPT set in the initial vehicle EOL as variables (AUTH_RAND = AUTH_Frand (ENG_RAND, BODY_ENCRYPT). Then, the generated authentication random number (AUTH_RAND) is transmitted to the engine ECU 40 (S408).

엔진 ECU(40)는 차체인증모듈(50)에서 사용한 동일한 암호화 변수를 가지고 자체 인증용 난수를 생성(AUTH_RAND_ecu = AUTH_Frand(ENG_RAND, BODY_ENCRYPT))한다(S410).The engine ECU 40 generates a random number for self authentication with the same encryption variable used in the vehicle body authentication module 50 (AUTH_RAND_ecu = AUTH_Frand (ENG_RAND, BODY_ENCRYPT)) (S410).

그리고 엔진 ECU(40)에서 자체 생성한 자체 인증용 난수(AUTH_RAND_ecu)와 차체인증모듈(50)에서 수신한 인증용 난수(AUTH_RAND)가 일치하는지 비교하여(S412), 서로 일치하면 인증을 통과한 것으로 판단하여 2차 시동키 인증 루틴을 수행한다.In addition, the self-authentication random number (AUTH_RAND_ecu) generated by the engine ECU 40 and the authentication random number (AUTH_RAND) received by the vehicle body authentication module 50 are compared with each other (S412). Determine and execute the second start-up key authentication routine.

서로 일치하지 않으면 인증 실패로 판단하여 엔진 시동을 금지하여(S424), 제3자 등에 의한 차량의 도난을 방지한다.If they do not coincide with each other, it is determined that the authentication has failed and the engine is prohibited from starting (S424) to prevent theft of the vehicle by a third party.

1차 차체 인증 통과시 엔진 ECU(40)는 다시 시동키 트랜스폰더(10a)와의 정보교환과 비교로 2차 시동키 인증 루틴을 수행한다.Upon passing the primary vehicle body authentication, the engine ECU 40 again performs the secondary start key authentication routine in comparison with the exchange of information with the start key transponder 10a.

먼저, 시동키(10)가 온되면(S414) 안테나 코일(20)에 의해 시동키 트랜스폰더(10a)에 전원이 인가되어, 시동키 ID와 시동키 암호화코드를 안테나 코일(20)과 이모빌라이저(30)를 통해 엔진 ECU(40)에 전송한다(S416).First, when the ignition key 10 is turned on (S414), power is applied to the ignition key transponder 10a by the antenna coil 20, and the ignition key ID and the ignition key encryption code are transmitted to the antenna coil 20 and the immobilizer ( 30 is transmitted to the engine ECU 40 (S416).

상기 엔진 ECU(40)는 수신된 시동키 ID 및 시동키 암호화코드가 초기 자동차 EOL에서 설정된 시동키 ID 및 시동키 암호화코드와 일치하는지 비교하여(S418), 일치할 경우에는(인증 통과시에는) 엔진의 소정의 신호를 인가하여 차량의 시동이 가능하게 한다(S420).The engine ECU 40 compares the received start key ID and the start key encryption code with the start key ID and the start key encryption code set in the initial vehicle EOL (S418), and if they match (when passing the authentication), A predetermined signal of the engine is applied to enable starting of the vehicle (S420).

이때, 수신된 시동키 ID 및 시동키 암호화코드가 일치하지 않을 경우에는 엔진 시동을 금지하여(S422), 제3자 등에 의한 차량의 도난을 방지한다.At this time, if the received start key ID and the start key encryption code do not match, the engine is prohibited from starting (S422) to prevent theft of the vehicle by a third party or the like.

이와 같이 탈거가 불가능하게 차체 구조물(60)에 견고히 장착된 차체인증모듈(50)을 추가하고 차량 시동시 1차 차체 인증 루틴을 수행하여, 인증 통과시에만 2차 시동키 인증 루틴을 수행함으로써 차량 도난 방지의 보안을 강화할 수 있는 것이다. In this way, by removing the vehicle body authentication module 50 firmly mounted on the body structure 60 so as not to be detached and performing the first body body authentication routine when starting the vehicle, the vehicle is executed by performing the second start key authentication routine only when the authentication passes. It can strengthen the security of anti-theft.

이상에서 살펴본 바와 같이 본 발명에 의하면, 차체 구조물에 탈거가 어렵게 장착된 차체인증 모듈의 추가로 인해 차량 보안성을 강화하여 휴대가 용이한 엔진 ECU-시동키 세트-시동키 어셈블리에 의해서도 도난당할 염려가 없다.As described above, according to the present invention, it is possible to be stolen by the engine ECU-start key set-start key assembly, which is easy to carry by strengthening the vehicle security due to the addition of the body authentication module that is hardly detached from the body structure. There is no.
