PROBLEM TO BE SOLVED: To further accurately calculate a state amount of a vehicle which is used for the attenuation force control of a damper when the vehicle turns.SOLUTION: Steering influence amount correction means (53, 54 and 35) which correct wheel speed variation amounts (Vw for use in the calculation of ΔVw) so that change amounts (Vb, Vb) of the wheel speed variation amounts generated by an influence of steering are eliminated comprise: a rear wheel turning radius calculation means (80A) which calculates turning radii R, Rof a right rear wheel and a left rear wheel; front wheel turning radius calculation means (80B) which calculates turning radii R, Rof a right front wheel and a left front wheel on the basis of the turning radii of the calculated right rear wheel and the left rear wheel, and a wheel base; and change amount calculation means (80C, 54) which calculate change amounts (Vb, Vb) of the wheel speed change amounts generated by the influence of steering on the basis of front wheel turn ratios (RR, RR) being ratios of the turning radii of the right front wheel and the left front wheel with respect to a vehicle body turning radius (R).SELECTED DRAWING: Figure 10

    【課題】車両が旋回しているときにもダンパの減衰力制御に供される車両の状態量をより高精度に算出できるようにする。【解決手段】転舵の影響による車輪速変動量の変化分(VbFL、VbFR)を除去するように車輪速変動量(ΔVwの算出に用いるVw)を補正する転舵影響分補正手段(53、54、35)が、右後輪および左後輪の旋回半径RRR、RRLを算出する後輪旋回半径算出手段(80A)と、算出された右後輪および前記左後輪の旋回半径とホイールベースとに基づいて右前輪および左前輪の旋回半径RFR、RFLを算出する前輪旋回半径算出手段(80B)と、右前輪の旋回半径および左前輪の旋回半径の車体旋回半径(R)に対する比である前輪旋回半径比(RRFL、RRFR)に基づき、転舵の影響による車輪速変動量の変化分(VbFL、VbFR)を算出する変化分算出手段(80C、54)とを備えるよう構成する。【選択図】図10
