SUSPENSION CONTROL APPARATUS

An object of the present invention is to provide a suspension control apparatus allowing a vehicle state to be easily estimated with use of a vehicle height sensor. A controller includes an external force estimation portion , which calculates an external force applied to a vehicle body from a displacement calculated from a vehicle height sensor , a vertical force calculation portion A, which calculates a vertical force of the vehicle body from the calculated external force, a sprung acceleration calculation portion B, which calculates an acceleration from the calculated vertical force, a filter portion C, which estimates a sprung speed of the vehicle body from the calculated acceleration, and a damping characteristic determination portion , which acquires a damping characteristic based on the estimated sprung speed.
