이하 첨부된 도면을 참조하면서 본 발명의 실시 예에 따른 차량용 CAN 통신시스템에 대해 보다 자세하게 설명하기로 한다.Hereinafter, a vehicle CAN communication system according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 일 실시예에 따른 차량용 CAN 통신 시스템의 블록 구성도이다.2 is a block diagram of a vehicle CAN communication system according to an embodiment of the present invention.

일반적으로, 차량용 CAN 통신 시스템은 중앙 제어기와 다수의 서브 제어기들이 CAN 통신 버스에 연결되어 서로 다른 데이터들을 상호 송수신하는데, 본 발명에서는 상기 중앙 제어기의 한 종류이며, 전차종에 사용되는 EMS(Engine Management System)를 통해 설명하기로 한다.In general, a vehicle CAN communication system for a vehicle is a central controller and a plurality of sub-controllers are connected to the CAN communication bus to transmit and receive different data to each other, in the present invention is a kind of the central controller, the EMS (Engine Management) used for all models System) will be described.

도 2를 보면, 차량용 CAN 통신 시스템은 차량용 CAN 통신 버스(131, 132)를 통해 상호 연결되어 서로 다른 데이터를 송수신하는 EMS(110)와 다수의 서브 제어기(140)들을 포함한다.Referring to FIG. 2, a vehicle CAN communication system includes an EMS 110 and a plurality of sub-controllers 140 connected to each other through a vehicle CAN communication bus 131 and 132 to transmit and receive different data.

양단간의 전위차를 일정하게 유지하는 제 1 및 제 2 저항(111, 121)과 연결된 차량용 CAN 통신 버스(131, 132)를 통해, 중앙 제어기인 EMS(110)와 다수의 서브 제어기(140)들간의 데이터 송수신 및 각 서브 제어기들간의 데이터 송수신이 이루어진다. 이를 위해 장착되는 두 개의 저항 중, 제 1 저항(111)은 상기 CAN 통신 버스(131, 132)의 일측에 연결된 EMS(110)내에 장착되며, 제 2 저항(121)은 CAN 통신 버스의 타측에 연결된 것을 특징으로 한다.Through the vehicle CAN communication buses 131 and 132 connected to the first and second resistors 111 and 121 to keep the potential difference between both ends constant, the EMS 110 between the central controller and the plurality of sub-controllers 140 Data transmission and reception and data transmission and reception between each sub controller are performed. Among the two resistors mounted for this purpose, the first resistor 111 is mounted in the EMS 110 connected to one side of the CAN communication buses 131 and 132, and the second resistor 121 is connected to the other side of the CAN communication bus.

This maintains a constant potential difference regardless of which system is connected on the vehicle CAN communication buses 131 and 132, thereby keeping the state of the vehicle CAN communication bus stable.

한편, 본 발명을 통해 고정 위치에 장착되는 두 개의 저항(111, 121)값은 55Ω내지 65Ω정도로 하며, 일반적으로 60Ω정도를 기준으로 한다.On the other hand, the two resistors (111, 121) to be mounted at a fixed position through the present invention is 55 to 65 Ω, based on 60 Ω in general.

이상에서 설명한 본 발명에 따르면, 양단간의 전위차 유지를 위해 장착시키는 두 저항의 위치를 캔 통신 버스의 일측에 연결된 EMS 및 캔 통신 버스의 타측에 각각 연결함으로써, 상기 차량용 CAN 통신 버스 상에 어떠한 제어장치가 연결되더라도, 어떤 제어장치에 저항을 장착할 것인가에 대한 설계상의 혼란을 해결할 수 있는 효과가 있다. 즉, 상기와 같은 병렬 저항의 고정된 장착 위치를 표준화함으로써, 차종별 또는 적용 시스템별로 문제가 되었던 설계상의 혼란을 방지할 수 있는 효과가 있다.According to the present invention described above, by connecting the positions of the two resistors for mounting the potential difference between both ends to the EMS and the other side of the CAN communication bus connected to one side of the can communication bus, respectively, any control device on the vehicle CAN communication bus Even if is connected, there is an effect that can solve the design confusion about which control unit to install the resistor. That is, by standardizing the fixed mounting position of the parallel resistance as described above, there is an effect that can prevent the design confusion that was a problem for each vehicle type or application system.
