VEHICULAR SUSPENSION CONTROL APPARATUS

PROBLEM TO BE SOLVED: To provide a vehicular suspension control apparatus capable of changing an attenuation coefficient, in which pitch behavior when a front wheel rides over a protrusion is suppressed and riding comfort when a rear wheel rides over the protrusion is satisfactorily kept.SOLUTION: A vehicular suspension control apparatus controls a vehicular suspension that includes a shock absorber whose attenuation coefficient can be changed in each wheel of a vehicle. For a wheel where large sprung behavior exceeding a reference is determined to occur, an attenuation coefficient is made a hard value. For example, while a vibration occurs in a vehicular body 10 as a result of riding of a front wheel 16 over a rise point 54 of a road surface, the attenuation coefficient of a rear wheel 34 is made a hard value. Then, when it is determined that a rear-wheel rise point arrives where the rear wheel 34 approaches the rise point of the road surface, the attenuation coefficient of the rear wheel is switched to a soft value that is softer than the hard value.SELECTED DRAWING: Figure 4 【課題】この発明は、減衰係数の変更が可能な車両用サスペンションの制御装置に関し、前輪が突起を通過する際のピッチ挙動を抑制し、かつ、後輪が突起を通過する際の乗り心地を良好に維持することを目的とする。【解決手段】減衰係数が変更可能なショックアブソーバを車両の各輪に備える車両用サスペンションを制御する。基準を超える大きなばね上挙動が生じていると判断される車輪については、減衰係数をハード値とする。例えば、前輪１６が路面の上昇点５４に乗り上げた結果、車体１０に振動が生じている間は後輪３４の減衰係数をハード値とする。その後、後輪３４が路面の上昇点に差し掛かる後輪上昇時点が到来したと判断される際に、当該後輪の減衰係数を、ハード値に比してソフトなソフト値に切り替える。【選択図】図４
