Classification: CPC B | IPC B

Claim 0:
1. A damping control device for a vehicle, comprising:
a control force generating device having an active actuator, the control force generating device configured to generate a control force in a vertical direction between at least one wheel suspended from a vehicle body of the vehicle and the vehicle body; and
a controller configured to reduce, by controlling the control force generating device to change the control force, vibration of the vehicle body that is caused by vibration occurring in the at least one wheel in response to vertical road surface displacements while the vehicle is traveling, wherein
the controller is configured to:
acquire, as sampled values, road surface displacement related values that are values related to the vertical road surface displacements in a predetermined sampling zone;
acquire an amplitude index indicating a magnitude of an amplitude of the sampled values;
determine an operation delay period of the control force generating device based on the magnitude of the amplitude indicated by the amplitude index;
calculate 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
transmit, 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.
