이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명하기로 한다. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 차량의 캔 시스템을 도시한 도면이다. 도면을 참조하면, 차량의 캔 시스템은 크게 바디컨트롤모듈(Body Control Module;10)과, 드라이브도어모듈(Driver Door Module;20)과, 어시스트도어모듈(Assist Door Module;30)과, 파워씨트ECU모듈(Power Seat ECU Module;40) 및 틸트ECU모듈(Tilt ECU Module;50)로 구성된다. 1 is a view showing a can system of a vehicle according to the present invention. Referring to the drawings, the can system of a vehicle is largely a body control module (10), a drive door module (20), an assist door module (30), and a power seat ECU It consists of a module (Power Seat ECU Module 40) and a tilt ECU module (Tilt ECU Module) 50.

바디컨트롤모듈(10)은 차량 내의 각종 램프, 와이퍼, 각종 장치간의 타이밍을 제어하는 블럭으로서, 차량의 키 삽입 유무, ACC 및 이그니션 전원관계, 알터네이터(Alternator) 동작관계, 스피드 연산관계, 키리스(Keyless) 동작신호 등을 제 어한다. The body control module 10 is a block for controlling timing between various lamps, wipers, and various devices in the vehicle. The body control module 10 includes a key insertion state, an ACC and ignition power relationship, an alternator operation relationship, a speed operation relationship, and a keyless Keyless) Control operation signal.

드라이브도어모듈(20)은 미러(Mirror)의 동작신호, 폴드(fold)의 동작신호, 윈도우의 동작신호, 메모리 관련 신호 등을 제어하며, 파워씨트ECU모듈(40) 및 틸트ECU모듈(50)과의 제어신호를 제어한다. The drive door module 20 controls an operation signal of a mirror, an operation signal of a fold, an operation signal of a window, a signal related to a memory, and the like. The power seat ECU module 40 and the tilt ECU module 50 are controlled. To control the control signal.

어시스트도어모듈(30)은 조수석 도어의 잠금 여부, 도어 개폐 여부 및 미러 제어와 윈도우의 개폐 기능을 제어한다.The assist door module 30 controls whether the passenger seat door is locked, whether the door is opened or closed, and the mirror control and the window opening and closing function.

파워씨트ECU모듈(40) 및 틸트ECU모듈(50)은 프론트 하이트 모터(Front height moter), 리어 하이트 모터(Rear height moter), 슬라이드 모터(Slide moter), 리클라인 모터(Recline moter) 등을 제어한다. The power seat ECU module 40 and the tilt ECU module 50 control the front height motor, the rear height motor, the slide motor, the recline motor, and the like. do.

이와 같이 크게 다섯 개의 블록으로 구성된 컨트롤유닛(10~50)들은 캔 버스(CAN_H, CAN_L) 프로토콜을 이용하여 두 가닥의 와이어(wire;60,70)를 통해 상호 연결 접속되어 있으며, 각 와이어(60,70) 간의 전압 차이를 이용한 신호로 상호 통신을 하면서 정보를 주고 받는다. As such, the control units 10 to 50 consisting of five blocks are interconnected through two strands of wires 60 and 70 using CAN bus (CAN_H and CAN_L) protocols. 70 is a signal using a voltage difference between the two to communicate with each other.

본 발명에 따르면, 각 컨트롤유닛(10~50)들과 와이어(60,70)가 연결되는 부위에는 보조와이어(80)가 추가 설치되어 연결 접속을 더욱 견고히 한다. 컨트롤유닛(10~50)과 와이어(60,70,80) 사이는 통상의 단자 형태로 접속 연결되며, 보조와이어(80)와 와이어(60,70) 사이의 연결은 초음파 융착으로 하는 것이 바람직하다. 초음파 융착은 음파 진동에 의한 마찰열을 발생시켜 접합면이 분자적으로 용해 접착되도록 하는 것으로, 이 방법은 충격이나 진동, 고온, 노이즈 등과 같은 열악한 차량 환경에 노출되어 있는 와이어(60,70,80) 간의 연결에 매우 적합하다. According to the present invention, the auxiliary wires 80 are additionally installed at portions where the control units 10 to 50 and the wires 60 and 70 are connected to further strengthen the connection connection. The control unit 10 to 50 and the wires 60, 70 and 80 are connected in a normal terminal form, and the connection between the auxiliary wire 80 and the wires 60 and 70 is preferably ultrasonic fusion. . Ultrasonic welding generates frictional heat due to sonic vibration so that the bonding surface is molecularly dissolved and bonded. This method is a wire (60, 70, 80) exposed to poor vehicle environment such as shock, vibration, high temperature, noise, etc. Very suitable for the connection between

한편, 보조와이어(80)는 와이어(60,70)와 와이어(60,70)를 연결하기 위한 커넥터(90)와 와이어(60,70) 사이에도 설치될 수 있다. 차량 바디는 크게 엔진유닛과 바디유닛과 트렁크유닛으로 구분할 수 있는데, 제조상 하나의 와이어를 엔진유닛으로부터 트렁크유닛까지 설치할 수 없기 때문에 각 컨트롤유닛(10~50)을 연결하는 와이어(60~70)는 복수의 커넥터(90)를 이용하여 각 유닛 사이를 연결하게 된다. 따라서, 하드웨어적으로 이러한 커넥터(90)와 와이어(60,70) 사이에도 접속 불량이 발생할 가능성이 있으므로, 보조 와이어(80)를 추가 설치함으로써 접속 불량에 의한 통신 에러를 효과적으로 방지할 수 있다. Meanwhile, the auxiliary wire 80 may also be installed between the connector 90 and the wires 60 and 70 for connecting the wires 60 and 70 and the wires 60 and 70. The vehicle body can be largely divided into an engine unit, a body unit, and a trunk unit. Since a wire cannot be installed from the engine unit to the trunk unit in manufacturing, the wires 60 to 70 connecting the respective control units 10 to 50 are A plurality of connectors 90 are used to connect the units. Therefore, since there is a possibility that a defective connection may occur between the connector 90 and the wires 60 and 70 in hardware, a communication error due to the poor connection can be effectively prevented by additionally installing the auxiliary wire 80.

이상, 상기 실시예에서는 캔 시스템을 구성하는 컨트롤유닛(10~50)으로 바디컨트롤모듈(10), 드라이브도어모듈(20), 어시스트도어모듈(30), 파워씨트ECU모듈(40), 틸트ECU모듈(50)을 예시하였지만, 본 발명은 이에 한정되지 않고 예를 들어 다른 트렌스미션컨트롤모듈(Transmission Control Module), 네비게이션컨트롤모듈(Navigation Control Module) 등과 와이어 사이의 연결 접속에도 적절한 변형을 통해 사용 가능함은 물론이다. In the above embodiment, the control unit 10 to 50 constituting the can system includes the body control module 10, the drive door module 20, the assist door module 30, the power seat ECU module 40, and the tilt ECU. Although the module 50 is illustrated, the present invention is not limited thereto, and the present invention can be used through suitable modification, for example, for connection connection between other transmission control module, navigation control module, and the like. Of course.
