PROBLEM TO BE SOLVED: To provide a vehicular suspension control apparatus allowing a change in an attenuation coefficient, with a novel technique for realizing a comfortable ride while sufficiently suppressing a change in the behavior of a vehicular body when a wheel passes through an irregular road surface.SOLUTION: In a case where a front wheel is on a projection of a road surface (clock time t1 to t3), with sprung acceleration of a rear wheel equal to or lower than zero (clock time t1 to t2), an attenuation coefficient of a shock absorber of the wheel is set at a hard value (refer to a second column in FIG. 4). In a case where the front wheel is on the projection of the road surface, with the sprung acceleration of the rear wheel higher than zero (clock time t2 to t3), the attenuation coefficient of the shock absorber of the wheel is controlled at a soft 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、車輪が路面の凹凸を通過する際の車体の挙動変化を十分に抑制しながら、良好な乗り心地を実現することを目的とする。【解決手段】前輪が路面の突起に乗っており(時刻t1から時刻t3)、かつ、後輪のばね上加速度がゼロ以下である場合は(時刻t1から時刻t2)、後輪のショックアブソーバの減衰係数をハード値とする(図4中、二段目の欄参照)。前輪が路面の突起に乗っており、かつ、後輪のばね上加速度がゼロを上回る場合は(時刻t2から時刻t3)、後輪のショックアブソーバの減衰係数をソフト値に制御する。【選択図】図4
