Abstract:
線形減衰係数 C s の大きさが、中周波バネ上加速度の最大振幅値αが大きいほど小さくなるように決定される。このため、減衰力制御装置が非線形 H ∞ 制御理論を用いてバネ上部材の振動を減衰制御している場合において、サスペンション装置に入力されている中周波バネ上加速度の最大振幅値αが小さいときは、線形減衰係数 C s が大きな値に設定される。よって、要求減衰力 F req も大きくなり、バネ上部材を速やかに制振することができる。また、中周波バネ上加速度の最大振幅値αが大きい場合には、線形減衰係数 C s が小さな値に設定される。よって、要求減衰力 F req も小さくなり、中周波振動入力時における乗り心地の悪化、特に振動速度が大きいときの乗り心地の悪化を抑制できる。

Abstract:
A suspension device includes a first and a second link that link a vehicle-body side member and a wheel supporting member to each other. The two links are linked to each other through an elastic linking portion. The rigidity of an elastic bush thereof is less than the rigidity of an elastic member of a linking portion of at least one of the two links with the wheel supporting member and the vehicle-body side member.
Abstract:
The invention relates to a method for determining at least one displacement state of a body (10) of a vehicle (1), comprising at least one wheel (2) which is spring-mounted on the vehicle body by means of a wheel suspension (6). According to the invention, a spring deflection (z rel ) of the wheel (2) is measured by means of a path or angle sensor (21); a spring deflection speed (z rel ) of the wheel (2) is determined by temporal differentiation of the spring deflection (z rel ) of the wheel (2); a vertical acceleration (z rel ) of the wheel (2) is measured by means of an acceleration sensor (22); a vertical speed (z RAD ) of the wheel (2) is determined by temporal integration of the vertical acceleration (z RAD ) of the wheel (2); and a vertical speed (z AUFB ) of the vehicle body (10) is calculated by forming a difference between the vertical speed (z RAD ) and the spring deflection speed (z rel ) of the wheel (2).
