The invention provides a vibration damping control device for a vehicle. The vibration damping control device can give consideration to both riding comfort performance and steering stability of the vehicle. A vibration damping control device for a vehicle according to the present invention is provided with a seat spring for suppressing vibration and a seat damper for damping the vibration between a frame and a seat, and is provided with a seat suspension having a variable spring constant and a variable damping coefficient. In order to avoid the occurrence of resonance, a seat spring upper acceleration and a resonance frequency of resonance, which are generated when the vibration corresponding to fluctuations in the vehicle spring lower acceleration propagates to the seat spring upper portion via the vehicle spring upper portion and the seat spring lower portion, are estimated. A target value of the acceleration on the seat spring, which is obtained by changing the estimated value of the acceleration on the seat spring, is calculated by reducing the actual value of the acceleration on the seat spring; the spring constant and the attenuation coefficient are respectively set to achieve a target value of acceleration on the seat spring before the vibration propagates to the upper portion of the seat spring.

    本发明提供一种能够兼顾车辆的乘坐舒适感性能和操纵稳定性的车辆的减振控制装置。本发明的车辆的减振控制装置在车架与座椅之间具有抑制振动的座椅弹簧以及使所述振动衰减的座椅减震器,配备有弹簧常数及衰减系数分别可变的座椅悬架,其中,推定在与车辆弹簧下加速度的变动相对应的所述振动经由车辆弹簧上部分以及座椅弹簧下部分传播给座椅弹簧上部分的情况下产生的座椅弹簧上加速度、以及共振的共振频率,为了避免所述共振的发生,并且减小所述座椅弹簧上加速度的实际值,而计算对所述座椅弹簧上加速度的推定值进行变更而得到的所述座椅弹簧上加速度的目标值,分别设定在所述振动传播到所述座椅弹簧上部分之前实现所述座椅弹簧上加速度的目标值的所述弹簧常数以及所述衰减系数。
