    • In a vibration control apparatus, a physical value influencing characteristics of a suspension for supporting a vibrating body and a state value representing movement of the suspension are detected. A frequency distribution of these values with respect to levels is calculated every predetermined period of time. A target control force is calculated on the basis of the frequency distribution in consideration of a continuous change in external state. An actual control force (detection control force) is calculated by the detected physical value. The suspension characteristics are continuously, variably controlled so as to equivalently generate a control force corresponding to a difference between the target and detection control forces. As a result, the target control force is equivalently applied to the suspension, thereby damping the vibrations. The vibration control apparatus can generate an optimal target control force free from the influence of an external state change on the basis of the frequency distribution of the state and physical values of the suspension.
    • 在振动控制装置中,检测影响用于支撑振动体的悬架的特性的物理值和表示悬架的移动的状态值。 在每个预定时间段内计算这些值相对于电平的频率分布。 考虑到外部状态的连续变化,基于频率分布来计算目标控制力。 通过检测到的物理值计算实际控制力(检测控制力)。 悬架特性是连续可变地控制的,以等效地产生对应于目标和检测控制力之间的差的控制力。 结果,目标控制力等效地施加到悬架,从而阻尼振动。 振动控制装置可以根据暂停状态和物理值的频率分布,产生不受外部状态变化影响的最佳目标控制力。
