Description
Claims (1)
- 車両の各車輪を支持する車軸と車体との間に配置され、当該車両の車高を車輪毎に流体の供排により変化させるための車高調整手段と、
各車輪の装着位置における車高値を検出するための車高検出手段と、
前記車高調整手段を制御して各車輪が所定の標準車高と一致するように制御する標準車高制御を含む車高制御を実行するための車高制御手段と、
前記車高調整手段における流体の圧力値を検出する圧力検出手段と、
前記圧力検出手段の検出した圧力値が所定しきい値を超えた場合に前記車高制御手段の制御を一時停止させる制御停止手段と、
前記車両が存在する路面の状態を推定する路面推定手段と、
前記制御停止手段が前記車高制御手段の制御を一時停止させているときに前記路面推定手段の推定結果に基づいて前記車両が所定条件を満たす路面に移動したことを検出した場合に前記制御停止手段による制御の一時停止を解除し前記車高調整手段の制御を可能とする制御復帰手段と、
を含み、
前記制御復帰手段は、前記制御停止手段による制御一時停止中に前記車両の走行速度が所定基準速度より低い場合でも、前記路面推定手段が前記車両の4つの車輪のうち一方の対角線上に配置された2つの車輪の車高値の和と他方の対角線上に配置された2つの車輪の車高値の和をとり、その2つの和の差をとったときの符号がそれ以前の状態から反転したことに基づき路面の状態を推定した場合、前記車両が前記所定条件を満たす路面に移動したことを検出したと判定し、前記制御の一時停止を解除することを特徴とする車高調整装置。
