Abstract
There is provided a damper control device and a suspension apparatus that are capable of effectively preventing a posture change such as pitching or rolling of the body of a vehicle. To achieve the above object, a damper control device of the present invention is designed to control a damping force of a damper in accordance with a rate of change in acceleration or a rate of change in angular acceleration. If there is a time delay in the rising of the acceleration acting on the vehicle body with respect to the driving operation being performed by the driver of the vehicle, the rate of change in the acceleration has a phase lead relative to the acceleration, and accordingly, the rate of change has only a short time delay with respect to the driving operation.
