Description
のとき、つまりバネ上上下速度とダンパ速度とが同方向(同符号)であるとき、ダンパ4のアクチュエータ5は減衰力を増加させる方向に制御される。一方、
dX2/dt×d(X2−X1)/dt≦0
のとき、つまりバネ上上下速度とダンパ速度とが逆方向(逆符号)であるとき、ダンパ4のアクチュエータ5は減衰力を減少させる方向に制御される。
4 ダンパ
5 アクチュエータ(減衰力制御手段)
31 車高調整手段
S サスペンション
W 車輪
Claims (1)
- 車輪(W)を車体(1)に懸架するサスペンション(S)のダンパ(4)の減衰力を制御する減衰力制御手段(5)と、サスペンションバネとして機能する、バネ定数が可変の空気バネと、この空気バネのバネ定数を調整するバネ定数調整手段とを備えた車両用サスペンション装置であって、
減衰力制御手段(5)への通電が遮断され、該減衰力制御手段(5)によるダンパ(4)の減衰力の制御が不能となって該減衰力が低減衰の状態で固定されたときに、バネ定数調整手段は前記空気バネのバネ定数を減少させることを特徴とする車両用サスペンション装置。
