Description
このS16にてハンドル2の操舵角を演算し終えたら制御処理を終了する。
Claims (2)
- ハンドルの操舵角を検出する操舵角センサと、
前記ハンドル側に連結される入力軸及び転舵輪側に連結される出力軸を有し、ステータを車両のボディ側に取り付けたモータを回転駆動させることにより前記入力軸−前記出力軸間の伝達比を変化させる伝達比可変手段と、
前記出力軸と前記モータの回転軸との相対回転を制限することによって前記入力軸と前記出力軸の相対的な回転を禁止するロック機構と、
前記操舵角センサが作動異常となった場合に、前記ロック機構をロック状態として前記入力軸と前記出力軸の相対的な回転を禁止させ、前記モータの回転軸の回転角を検出する回転センサの出力信号に基づいて前記ハンドルの操舵角を取得する操舵角取得手段と、
を備えた車両操舵装置。 - 前記操舵角取得手段は、前記操舵角センサの作動異常時におけるハンドル操舵角に前記回転センサの出力を加えることにより前記ハンドルの操舵角を演算することを特徴とする請求項1に記載の車両操舵装置。
