Abstract
In order to improve vibration attenuation (during engine shake and idling for example), reduce power consumption and increase the longevity of elements associated with the application of a high voltage to electrodes which control the viscosity of an ERF in an orifice passage, the rate at which the ERF is flowing in the passage is estimated based on a relative displacement parameter or the like, and used to modify the actually applied voltage level.
