<P>PROBLEM TO BE SOLVED: To improve an estimated accuracy of a stroke speed of a suspension. <P>SOLUTION: A control device 20 calculates a reference vehicle body speed component Vb0 that is the component of the vehicle body speed excluding the vehicle planar motion component and the road surface disturbance component based on the wheel speed ωs. Subsequently, the stroke speed Vz of the suspension is calculated based on the calculated reference vehicle body speed component Vb0. Then, the stroke condition of the suspension is controlled based on calculated stroke speed Vz. Accordingly, even if the vehicle planar motion component and the road surface disturbance component are mixed for instance, and the detection accuracy of wheel speed ωs decreases, the decrease in the estimated accuracy of the reference vehicle body speed component Vb0 can be controlled. Consequently, the estimated accuracy of scanning line frequency Vz of the suspension can be improved. <P>COPYRIGHT: (C)2013,JPO&INPIT |
