Abstract

본 발명은 자동차의 4륜 조향 시스템에 관한 것으로, 특히, 자동차의 4륜 조향 시스템에 있어서, 마이컴부(50)를, 소정의 접속방법으로 접속된 제1마이컴(51)과 제2마이컴(52)으로 구성하여 소정의 방법에 의해 상호 진단기능을 수행함과 동시에, 상기 제1마이컴 (51) 또는, 제2마이컴 (52) 중 어느 하나의 마이컴이 제 기능을 수행할 수 없을 시 그 기능을 대체하여 수행할 수 있도록 구성함을 특징으로 하는 듀얼 마이컴을 이용한 4륜 조향 시스템의 페일 세이프 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a four-wheel steering system of a motor vehicle, and more particularly, in a four-wheel steering system of a motor vehicle, a first microcomputer 51 and a second microcomputer 52 in which a microcomputer unit 50 is connected by a predetermined connection method. And perform the mutual diagnosis function by a predetermined method, and replace the function when any one of the first microcomputer 51 or the second microcomputer 52 cannot perform the first function. It relates to a fail-safe method of a four-wheel steering system using a dual microcomputer, characterized in that configured to be performed by.
