Abstract

본 발명은 에이비에스(ABS)에서 휠스피드 센서 고장시 보상방법에 관한 것으로, 본 발명에 의하면, 종래 4개 휠스피드 센서중 어느하나라도 고장나면 ABS동작을 바로 중단시키는 것을 개선하여 사용가능한 휠 스피드 센서를 찾아 고장난 상대편 휠 또는 전방 및 후방 휠을 제어하는 것에 의해 ABS장치를 가진 차량에서 주행안전성을 최대한 보장할 수 있는 장점이 있다.

Description

에이비에스(ABS)에서 휠스피드 센서 고장시 보상방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 종래의 ABS 제어방법을 나타내는 플로우챠트.
제2도는 본 발명에 따른 휠스피드 센서 고장시 보상방법을 나타내는 플로우챠트.

Claims (1)

  1. ABS 시스템의 제어방법에 있어서, 4개 휠 스피드 센서가 정상동작중인지를 판단하고, 4개 휠 스피드 센서가 정상동작을 하지 않는 것으로 판명되었을 때 고장난 센서가 1개 인지를 판단하는 단계와, 고장난 스피드센서가 1개 일때 고장이 아닌 전방 또는 후방 휠의 스피드 센서에서 감지한 스플리트 뮤(SPLIT-μ)값이 매우 큰 지를 판단하는 단계와, 스플리트 뮤 값이 매우 크지 않을때 정상인 상대쪽 휠 스피드센서 신호를 고장난 휠 스피드 센서값으로 대치하고 나서 ABS 동작모드를 수행하는 단계와, 스플리트 뮤 값이 큰것으로 나타날 때, 고장난 전방 또는 후방 휠은 ABS동작을 중단시키고, 나머지 휠만을 ABS모드로 동작시키는 단계와, 고장난 센서가 1개이상일때 다시 고장난 센서가 2개인지를 판단하고, 고장난 센서가 2개이면 그 고장난 센서 모두가 전방 또는 후방 휠에 위치하는가를 판단하는 단계와, 고장난 2개센서 모두가 전방 또는 후방 휠에 위치하는 것으로 판명되었을 때 고장난 전방 또는 후방 휠은 ABS동작을 중단시키고, 나머지 휠만을 ABS모드로 동작시키는 단계로 이루어진 에이비에스(ABS)에서 휠스피드 센서 고장시 보상방법.
