Description

캔 통신 장치{Apparatus for controller area network}CAN communication device {Apparatus for controller area network}

본 발명은 CAN 통신 장치에 관한 것이다.The present invention relates to a CAN communication device.

고속 CAN(Controller Area network) 통신을 이용하는 차량 내 정보통신이 모든 차량에 적용 중에 있다. 고속 CAN 통신은 엔진, 구동계, 샤시 등의 전자제어유니트(ECU)에서 중요한 데이터를 송/수신하는 통신버스로서 차속, 엔진 RPM, 브레이크 제어 정보, 유니트 상태 정보, 경고등 표시 등의 데이터의 적절한 시점의 적절한 전송/처리가 중요해지고 있는 실정이다.In-vehicle information communication using high-speed CAN (Controller Area network) communication is being applied to all vehicles. High-speed CAN communication is a communication bus that transmits / receives important data from an electronic control unit (ECU) such as an engine, drive system, chassis, etc., at an appropriate time of data such as vehicle speed, engine RPM, brake control information, unit status information, and warning light indication. Proper transmission / processing is becoming important.

도 1은 종래의 CAN 통신에서의 버스 구조를 도시한 그림이다.1 is a diagram illustrating a bus structure in a conventional CAN communication.

기존의 CAN 통신은 아래 그림과 같이 두 개의 종단 저항을 이용하여 클로즈(closed)된 버스(bus)를 구성하고 각 전자제어유니트(ECU)별로 스터브(stub)를 만들어 서로의 전자제어유니트간에 통신을 하는 방식으로 구성된다. 다만 진단 통신을 위하여 OBD(On Board Diagnostics) 터미널(10) 부분만 오픈(open)되어 있는 형태로 버스를 구성하게 된다.Conventional CAN communication consists of a closed bus using two termination resistors as shown in the figure below and creates a stub for each electronic control unit (ECU) to communicate with each other. It is organized in such a way. However, only the OBD (On Board Diagnostics) terminal 10 part is opened for diagnostic communication, and the bus is configured.

상기 OBD 터미널(10)은 스캐너와 같은 차량용 진단 장치에 접속되어 차량 진단 시에 사용되거나, 또는, 공장 인라인에서 생산 차량 정보 코딩 작업 중에 정보 입출력을 위해 사용되는데, 이때, 스터브(stub) 길이에 따라 전체 버스에 오작동을 유발하거나 에러 프레임(error frame)을 만들게 된다.The OBD terminal 10 is connected to a vehicle diagnostic apparatus such as a scanner and used for vehicle diagnosis, or used for input and output of information during production vehicle information coding operation in a factory inline, wherein the length of the stub depends on a stub length. It may cause a malfunction or create an error frame on the entire bus.

또한, 차량 주행 상태에서 통신 데이터를 전송하기 위해서 과도상태를 지나게 되는데 오픈(open)되어 있는 부분에서 반사파 다량 발생 및 전도성 노이즈 유입으로 인하여 신호 안정성 측면에 문제가 있다.In addition, a transient state is passed to transmit communication data in a vehicle driving state, and there is a problem in terms of signal stability due to generation of a large amount of reflected waves and inflow of conductive noise in an open part.

본 발명은 노이즈 유입을 방지하여 신호 안정성을 향상시키는 CAN 통신 장치를 제안한다.The present invention proposes a CAN communication device that prevents noise inflow and improves signal stability.

본 발명은 폐루프를 이루는 종단 저항을 배선에 두지 않는 버스 구조를 가지며, 차량 진단 터미널인 OBD 터미널의 내부에 상기 종단저항이 삽입된다.The present invention has a bus structure in which a terminating resistor constituting a closed loop is not placed on a wiring, and the terminating resistor is inserted into an OBD terminal which is a vehicle diagnostic terminal.

상기 OBD 터미널은, 자가진단장치가 삽입되어 신호 전달 통로 역할을 하는 두개의 터미널 심부와, 상기 터미널 심부 사이에 위치하여 저항체 역할을 하는 저항체 기판과, 상치 터미널 심부를 차량측 배선에 연결시키는 덮개를 포함한다.The OBD terminal includes two terminal cores into which a self-diagnostic device is inserted to serve as a signal transmission path, a resistor substrate positioned between the terminal cores to serve as a resistor, and a cover connecting the upper terminal cores to the vehicle side wiring. Include.

상기 저항체 기판은 저항성분 증착 후 에지 공정을 통해 저항체 역할을 수행하도록 제작된 PCB 기판임을 특징으로 한다. 상기 터미널 심부와 저항체 기판은 본딩 작업을 통해 연결됨을 특징으로 한다.The resistor substrate may be a PCB substrate manufactured to perform a role of a resistor through an edge process after resistive deposition. The terminal core portion and the resistor substrate may be connected through a bonding operation.

본 발명은 종단저항을 OBD 터미널 내부에 둠으로써, 노이즈 유입을 방지하여 신호 안정성을 향상시키는 효과가 있다.The present invention has an effect of improving signal stability by preventing the inflow of noise by placing the terminating resistor inside the OBD terminal.

이하, 본 발명의 실시 예들의 상세한 설명이 첨부된 도면들을 참조하여 설명될 것이다. 하기에서 각 도면의 구성요소들에 참조부호를 부가함에 있어 동일한 구성요소들에 대해서는 비록 다른 도면상에 표시되더라도 가능한 한 동일한 부호를 가지도록 하고 있음에 유의해야 한다. Hereinafter, a detailed description of embodiments of the present invention will be described with reference to the accompanying drawings. In the following description of the reference numerals to the components of the drawings it should be noted that the same reference numerals as possible even if displayed on different drawings.

도 2는 본 발명의 실시 예에 따른 CAN 통신 버스 장치를 도시한 구성도이다.2 is a block diagram illustrating a CAN communication bus apparatus according to an exemplary embodiment of the present invention.

CAN(Controller Area network) 통신은 자동차내에 적용되는 시리얼 네트워크 통신 방식으로서, 여러 가지 전자제어유닛(Electronic Contol Unit) 들을 병렬로 연결하여 각각의 전자제어유닛들과 서로 정보교환이 원활히 이루어져 우선 순위대로 처리하는 방식으로 각각의 전자제어유닛들간에 정보교환이 이루어진다는 장점과 여러가지 장치를 단지 2개의 선으로 컨트롤할 수 있다는 장점이 있다.CAN (Controller Area network) communication is a serial network communication method applied to automobiles. It connects various Electronic Control Units in parallel and exchanges information with each other electronically. Information exchange between the respective electronic control units, and various devices can be controlled by only two lines.

본 발명은 CAN 통신의 버스 구조에 있어 배선 사이에 종단저항을 두는 폐루프 형태의 버스 구조를 두지 않고 OBD 터미널 내부에 종단저항을 삽입하여 전도성 노이즈 유입을 방지하여 신호 안정성을 향상시킬 수 있다.The present invention can improve the signal stability by preventing the introduction of conductive noise by inserting a terminating resistor inside the OBD terminal without having a closed loop bus structure having a terminating resistor between wirings in the bus structure of the CAN communication.

종래에는 도 3과 같이 두개의 종단저항(31a,31b)을 이용하여 클로즈(closed)된 버스(bus)를 구성하고 각 전자제어유니트(ECU)별로 스터브(stub)를 만들어 전자제어유니트간 통신을 하였다.Conventionally, as shown in FIG. 3, a closed bus is formed using two termination resistors 31a and 31b and a stub is formed for each electronic control unit to communicate between the electronic control units. It was.

그러나, 도 3과 같이 배선 사이에 종단저항(31a, 31b)을 두는 폐루프 형태의 버스 구조를 가질 경우, 도 4와 같이 언더슈트(또는, 오버슈트) 노이즈 발생이 있었다. 따라서 이러한 언더슈트(under shoot) 노이즈 발생으로 인한 과도시간이 경과하여 안정화된 후에야 데이터를 읽어들여야만 했다.However, when a closed loop bus structure is provided in which termination resistors 31a and 31b are provided between the wirings as shown in FIG. 3, there is an undershoot (or overshoot) noise as shown in FIG. 4. Therefore, the data had to be read only after the transient time had stabilized due to the occurrence of such under shoot noise.

본 발명은 배선의 사이에 종단저항을 두는 폐루프 버스의 구조가 아니라, 차량진단 터미널인 OBD 터미널 내부에 직접 종단저항(31b)을 삽입함으로써 언더슈트(또는, 오버슈트)의 노이즈를 없앨 수 있다.The present invention can eliminate the noise of the undershoot (or overshoot) by inserting the terminating resistor 31b directly into the OBD terminal, which is a vehicle diagnostic terminal, rather than the structure of a closed loop bus having a terminating resistor between the wirings. .

즉, 본 발명은 도 2와 같이 일측 배선에 저항을 두고 있지만, 타측 배선의 종단에는 저항을 두지 않고 대신에 OBD 터미널 내에 종단 저항을 두는 구조를 가진다. 이때, OBD 터미널에 저항을 삽입함으로써 측정 신호의 노이즈를 제거할 수 있다.That is, the present invention has a structure in which a resistor is attached to one wiring as shown in FIG. In this case, noise may be removed from the measurement signal by inserting a resistor into the OBD terminal.

도 5는 본 발명에 따른 OBD 터미널의 구조체를 도시한 그림이다. 5 is a diagram illustrating a structure of an OBD terminal according to the present invention.

OBD 터미널은 OBD 터미널의 인입부에 삽입하는 두개의 터미널 심부(52)를 저항이 작은 성분으로 제작하고, 이러한 터미널 심부 사이에 저항체 기판(51)을 두어 터미널 심부와 저항체 기판을 일체화시켜 터미널 구조체를 형성한다. 상기 터미널 심부(52)는 ODB 터미널에 자가진단장치가 연결되는 경우, 신호 전달 통로 역할을 한다.In the OBD terminal, two terminal cores 52 inserted into the inlet of the OBD terminal are made of a low resistance component. A resistor substrate 51 is provided between the terminal cores to integrate the terminal core and the resistor substrate to form a terminal structure. Form. The terminal core 52 serves as a signal transmission passage when the self-diagnostic device is connected to the ODB terminal.

도 2 및 도 5에 도시된 바와 같이 OBD 터미널(10)의 뒤쪽으로는 상치 터미널 심부(52)를 차량측 배선(10a)에 연결시키는 덮개(53)를 장착하고 이를 차량측 배선에 장착한다.As shown in FIGS. 2 and 5, a cover 53 for connecting the upper terminal core portion 52 to the vehicle side wiring 10a is mounted to the rear side of the OBD terminal 10 and mounted on the vehicle side wiring.

상기 저항체 기판(51)은 PCB에 저항 성분을 증착한 후, 에지공정을 통해 제 거하여 형성한다. 상기와 같이 저항 성분이 형성된 저항체 기판은 터미널 심부에 있는 CAN 터미널과 얼라인먼트 공정을 통해 본딩작업을 하여 형성한다.The resistor substrate 51 is formed by depositing a resistive component on a PCB and then removing the resistor component through an edge process. The resistive substrate on which the resistive component is formed as described above is formed by performing a bonding process through an alignment process with a CAN terminal located at the core of the terminal.

상기와 같이 저항 성분이 삽입되는 OBD 터미널을 이용하여 차량 진단 측정을 수행할 경우, 도 4와 같은 언더슈트(또는, 오버슈트)의 노이즈가 감소되는 결과를 얻을 수 있다.As described above, when the vehicle diagnostic measurement is performed using the OBD terminal in which the resistance component is inserted, the noise of the undershoot (or overshoot) as shown in FIG. 4 may be reduced.

종단 저항을 가지는 종래의 폐루프 형태의 CAN 버스 구조하에서 도 4와 같은 언더슈트 노이즈가 발생되고 있지만, 도 2와 같은 CAN 버스 구조하에서 종단 저항이 삽입된 OBD 터미널 구조체를 이용하여 진단이 이루어질 경우, 도 6과 같이 언더슈트의 노이즈가 제거됨을 알 수 있다.Undershoot noise as shown in FIG. 4 is generated under a conventional closed loop CAN bus structure having a termination resistor. However, when diagnosis is performed using an OBD terminal structure having a termination resistor inserted under the CAN bus structure as shown in FIG. It can be seen that the noise of the undershoot is removed as shown in FIG. 6.

Therefore, the scope of the present invention is not to be determined by the embodiments described above, but will be apparent in the claims as well as equivalent scope.
