Abstract

사용되는 다수개의 전자 제어장치와 자기 진단장치간의 통신방식을 버스방식으로 하나의 통신선로로 모두 연결될 수 있도록 하여 필요한 데이타의 통신방식을 간소화할 수 있도록 하기 위하여, 통신방식과 통신속도와 데이타를 송수신할 수 있는 제1통신선로와 통신 가능상태를 알기 위한 신호와 어드레스 신호를 수신할 수 있는 제2통신선로에 모두 연결되어, 내장된 프로그램에 의해 정해진 동작을 수행하고, 데이타 통신이 가능해지면 제2통신선로를 통해 수신되는 어드레스 신호에 따라 해당장치의 통신프로토콜과 해당하는 통신데이타를 전송하는 다수개의 전자 제어수단과 ; 상기 제1통신선로와 제2통신선로에 연결되어 제1통신선로를 통하여 수신되는 신호에 의해, 해당하는 방식으로 데이타를 수신할 수 있도록 하는 자기 진단수단으로 이루어져 있는 전자 제어장치와 자기 진단장치간의 통신장치 및 그 방법에 관한 것.In order to simplify the communication method of necessary data by connecting the communication method between a plurality of used electronic control devices and the self-diagnosis device by a bus method, the communication method and communication speed and data are transmitted and received. It is connected to both the first communication line capable of communication and the second communication line capable of receiving an address signal and the signal for knowing the communication possible state, and performs a predetermined operation by the built-in program, and when the data communication becomes possible, the second A plurality of electronic control means for transmitting a communication protocol and corresponding communication data of the apparatus in accordance with the address signal received through the communication line; Between the electronic control device and the self-diagnostic device comprising a self-diagnostic means connected to the first communication line and the second communication line to receive data in a corresponding manner by a signal received through the first communication line. Of communication devices and methods thereof.

Description
