Abstract
【解決手段】 車輛に設けられる回転速度センサ(27)と、前記回転速度センサの出力信号に基づいて制御を行う制御手段(1)とを備えた車輛の制御装置において、前記制御手段は、前記回転速度センサの出力信号からノイズを検出するノイズ検出手段(3、4)と、前記検出したノイズのレベルと、予め設定したしきい値とを比較して前記出力信号に含まれるノイズが一時的なものであるか否かを判定するノイズ判定手段(S3)と、前記ノイズの判定結果が一時的なノイズと判定された場合には、予め設定したコーション制御を実行するコーション制御手段(S4)と、を備える。

Description
1)コネクタ接触不良
2)悪路走行時
3)回転速度センサ26、27の回転リングの歯欠けによる信号の波欠け
4)回転速度センサ近傍に設置された高周波アクチュエータの影響による電磁波ノイズ
5)路面状況の変化時(例えば、ウェット路面からドライ路面に切り換わった時)
等が考えられる。1)コネクタ接触不良と3)歯欠けは回転速度センサの異常と考えられるが他の要因は正常な回転速度センサであっても発生するノイズである。
