Abstract
A suspension control device which controls an operation of a suspension of a vehicle includes an operation-induced state quantity estimation portion which estimates an operation-induced state quantity caused by an operation of a vehicle, a road surface-induced state quantity estimation portion which estimates a road surface-induced state quantity caused by a road surface, an operation-induced state quantity conversion portion which converts the operation-induced state quantity into an operation-induced required damping force, a road surface-induced state quantity conversion portion which converts the road surface-induced state quantity into a road surface-induced required damping force, and a current value calculation portion which determines a current value to be applied to the suspension with reference to the operation-induced required damping force and the road surface-induced required damping force.
