Abstract: A vehicle vibration damping system includes a suspension; an actuator; and a control device configured to calculate a damping force to be applied to the sprung structure based on a theory of skyhook control, and control the actuator. The control device calculates the damping force based on a correction control parameter obtained by multiplying a control parameter of a denominator of a transfer function of the sprung structure with respect to a road surface displacement of a vibration model having a virtual skyhook damper by a function for canceling a coefficient of a control parameter term. The control parameter is a product of an attenuation coefficient of the skyhook damper and a Laplace operator. The function is a function having a coefficient of the control parameter term of the transfer function as a denominator, and includes at least a quadratic term of the Laplace operator in a numerator.
