    摘要： Shock absorbers of left and right front wheel suspensions and shock absorbers of left and right rear wheel suspensions each are constituted by a damping force adjustable hydraulic shock absorber provided with a frequency response unit. An actuator of a damping force variable mechanism provided to the shock absorber is driven and controlled by a controller. The controller variably adjusts the damping force between the soft side and the hard side by the damping force variable mechanism according to a vertical vibration when a vehicle body vertically vibrates at a low frequency. The controller does not adjust the damping force when the vehicle body vibrates at a higher frequency than the low frequency.

    摘要： By passing the vertical acceleration through a phase adjusting filter and a gain adjusting filter, the phase of the vertical acceleration is advanced by 49 degrees so that the phase difference with respect to the actual relative velocity becomes 180 degrees in the neighborhood of the vehicle body resonance point, thereby making the phase of the vertical acceleration, in effect, coincident with the phase of the relative velocity. In the neighborhood of the vehicle body resonance point (1 Hz), the gain of the estimated relative velocity takes a small value. In frequency regions other than the neighborhood of the vehicle body resonance point, the gain of the estimated relative velocity is increased. Consequently, the controlled variable in the neighborhood of the vehicle body resonance point increases, and the controlled variable in higher frequency regions decreases. Damping force is adjusted in correspondence to the controlled variable. Thus, it is possible to improve ride quality in the neighborhood of the vehicle body resonance point (1 Hz).

    摘要翻译： 通过使垂直加速度通过相位调整滤波器和增益调整滤波器，垂直加速度的相位提前49度，使得相对于实际相对速度的相位差在车身谐振附近变为180度 点，从而使垂直加速度的相位实际上与相对速度的相位一致。 在车体共振点（1Hz）附近，估计的相对速度的增益取小值。 在车体共振点附近的频率区域中，估计的相对速度的增益增加。 因此，车体共振点附近的受控变量增大，高频区域的受控变量减小。 阻尼力相应于受控变量进行调整。 因此，能够提高车体共振点附近的乘坐质量（1Hz）。

    摘要： The present invention provides a vehicle body attitude control apparatus capable of improvement of cornering operability, steering stability, and a ride comfort while a vehicle is running. A controller includes a gain, a determination unit, a multiplication unit, an FF control unit, a difference calculation unit, an FB control unit, an average value calculation unit, a target damping force calculation unit, and a damper instruction value calculation unit so as to enable such control that a pitch rate and a roll rate are set into a proportional relationship while the vehicle is cornering. The controller calculates a target pitch rate proportional to the roll rate, variably controls a damping force characteristic of a damping force variable damper disposed at each of front left, front right, rear left, and rear right wheels so as to achieve the target pitch rate, and generates a pitch moment to be applied to the vehicle body accordingly.
