车辆电控系统故障诊断的去抖动方法研究

Research on Debounce Method of Fault Diagnosis of Vehicle Electronic Control System

精确的故障诊断是对车辆电控系统功能的重要要求之一。然而车辆运行工况的复杂性,决定了故障的诊断具有一定的难度。尤其是某些故障在某些工况下,可能会短暂地报出来,但是并不是真实的有故障发生,会给诊断造成一定困难。本文针对故障诊断的这一难点问题,进行原始故障状态的去抖动方法研究。

Precise fault diagnosis is one of the important function of vehicle electronic control system.But complicated vehicle operating conditions make reality of it difficulty.Especially in some operating point,some fault will be reported sometimes but does not really happen.This situation makes precise fault diagnosis difficult.This article aims at solving this problem,and make some research on debounce methods.
