摘要 |
This invention relates to a vehicle suspension apparatus interposed between a vehicle body side and each wheel side and having variable damping force characteristics. The apparatus includes a shock absorber (b) which can switch the damping force characteristics on both extension and contraction sides in a plurality of stages by damping force characteristics changing means (a), and capable of being switched to characteristics under which damping coefficient ratio of the extension side to the contraction side is not greater than 1.0, damping force characteristics control means (e) having normal-time control means (d) for variably controlling the damping force characteristics of each shock absorber (b) on the basis of a car behavior detection signal detected by car behavior detecting means (c), and braking-time correction control means (g) provided in the damping force characteristics control means (e), for switching the damping force characteristics changing means (a) of the shock absorber (b) to the characteristics under which the damping coefficient ratio of the extension side to the contraction side is not greater than 1.0, when brake state detection means (f) detects the braking state of the vehicle. The apparatus can ensure a braking force by minimizing variations in ground contact load caused by a vehicle behavior produced by braking. <IMAGE> |
