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，使得垂直加速度的相位超前49度，以使得相对于实际相对速度的相位差在车体共振附近变为180度从而使垂直加速度的相位实际上与相对速度的相位一致。在车体共振点附近（1Hz），估计的相对速度的增益取小值。在车体共鸣点附近以外的频率区域中，估计的相对速度的增益增加。因此，车体共振点附近的控制量增加，高频域中的控制量减少。阻尼力根据受控变量进行调整。因此，可以提高车体共振点附近的乘坐舒适性（1Hz）。

摘要： PURPOSE: A suspension control system is provided to realize damping characteristic control of high accuracy and reduce cost for producing a suspension control system with a cheap acceleration sensor. CONSTITUTION: By passing the vertical acceleration through a phase adjusting filter(13) and a gain adjusting filter(14), 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).
