A suspension ECU 13 calculates a target characteristic changing coefficient a_new for changing a target characteristic, which is represented by a quadratic function, by use of the maximum actual roll angle ¦_max generated in a vehicle body during the current turning state and a turning pitch angle ˜_fy_max which is a fraction of an actual pitch angle ˜ generated as a result of turning, and changes the target characteristic by use of the coefficient a_new. Subsequently, the suspension ECU 13 calculates the difference ”˜ between the actual pitch angle ˜ and a target pitch angle ˜h corresponding to the actual roll angle ¦ on the basis of the changed target characteristic, and calculates a total demanded damping force F to be cooperatively generated by the shock absorbers so as to reduce the difference ”˜ to zero. Furthermore, in proportion to the magnitude of a lateral acceleration Gl, the suspension ECU 13 distributes the total demanded damping force F into a demanded damping force Fi on the turning-locus inner side and a demanded damping force Fo on the turning-locus outer side. |
