  "textContent": "A sprung structure is provided with an acceleration computing section. A damping force estimating section (16) of a relative velocity estimating section (12) estimates a damping force by reading information from a damping force characteristic storing section (14) in accordance with a valve opening degree instruction and the relative velocity between sprung and unsprung structures estimated in the last control cycle. An estimating and computing section 18 estimates the relative velocity between sprung and unsprung structures in accordance with the above acceleration and estimated damping force. A suspension system is controlled in accordance with the relative velocity.",
