1. An apparatus of controlling vehicle suspension, the apparatus comprising:
a variable damper mounted between a vehicle body and a wheel of a vehicle;
first acceleration sensors mounted at each corner of the vehicle body and configured to measure a vehicle body corner vertical acceleration;
second acceleration sensors mounted to each wheel of the vehicle and configured to measure a wheel vertical acceleration; and
a controller engaged to the first acceleration sensors and the second acceleration sensors and configured to estimate a road surface roughness according to the vehicle body corner vertical acceleration and the wheel vertical acceleration, to determine a virtual tire damping required damping force according to the estimated road surface roughness, and to adjust a damping force of the variable damper according to the determined virtual tire damping required damping force.
