- the orientation control means (32) is configured to calculate the various orientation control amounts on the basis of skyhook control.

-Skyhook control is performed by all of the actuators. This allows skyhook control to be inexpensively performed using all of the wheel speed sensors installed in the vehicle, without the use of a stroke sensor, sprung mass vertical acceleration sensor, or the like, as is usually necessary to perform skyhook control.

-In order to achieve control of the orientation of the sprung mass via skyhook control, feedback on the sprung mass speed is necessary. Stroke speed is a value detectable from the wheel speed sensor.

-However, adjusting damping force via skyhook control will vastly reduce estimation precision, creating the problem that a large orientation control force (damping force adjustment) cannot be applied in the conventional vehicle model.
