ABSTRACT:
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.
