Abstract
A suspension ECU computes an actual roll angle and an actual pitch angle of a vehicle, and computes a difference between a target pitch angle and the actual pitch angle. The ECU then computes a total demanded damping force which must be cooperatively generated by shock absorbers so as to decrease the computed difference to zero, and distributes the total demanded damping force in proportion to the magnitude of a lateral acceleration such that a demanded damping force on the turn-locus inner side becomes greater than a demanded damping force on the turn-locus outer side. Further, the ECU determines whether or not the vehicle body is vibrating in the vertical direction as a result of input of a road surface disturbance, calculates a vibration-suppressing damping force needed for damping the vibration, and determines the demanded damping forces by use of the vibration-suppressing damping force.
