Claim 9:
10. A damping control method for a vehicle configured to reduce, by controlling a control force generating device having an active actuator, the control force generating device to change a control force in a vertical direction, vibration of a vehicle body of the vehicle that is caused by vibration occurring in at least one wheel suspended from the vehicle body in response to vertical road surface displacements while the vehicle is traveling, the control force generating device being configured to generate the control force between the at least one wheel and the vehicle body, the damping control method comprising:
acquiring, as sampled values, road surface displacement related values that are values related to the vertical road surface displacements in a predetermined sampling zone;
acquiring an amplitude index indicating a magnitude of an amplitude of the sampled values;
determining an operation delay period of the control force generating device based on the magnitude of the amplitude indicated by the amplitude index;
calculating a target control force for reducing the vibration of the vehicle body based on the road surface displacement related values at a predicted passing position where the at least one wheel is predicted to pass after an elapse of the operation delay period from a current time; and
transmitting, to the control force generating device, a control command for causing the control force generating device to regulate the control force to agree with the target control force.
