Claim 0:
1. An active suspension device that is a control device for a variable damping force damper provided for damping a relative vibration between a vehicle body and a wheel, comprising:
a road surface height measurer which measures road surface heights at three or more points along a vehicle-width direction in front of a tire mounted on the wheel;
a position detector which detects a position at which a difference of the road surface height from an adjacent road surface height is equal to or larger than a predetermined threshold among the road surface heights at three or more points measured by the road surface height measurer; and
a road surface condition determiner which excludes a value of the road surface height at the position at which the difference detected by the position detector is equal to or larger than the predetermined threshold, and determines a condition of the road surface based on the road surface heights at positions at each of which the difference from an adjacent road surface height is smaller than the predetermined threshold.
