Adaptively controlled vibration damping support apparatus for vehicle power unit including engine

A vibration damping support apparatus for a power unit of an automobile, the power unit including an engine and being flexibly supported on a vehicle body of the automobile via a plurality of elastic mounts, comprising:

• oscillating means disposed between the vehicle body and the power unit, for oscillating the power unit with respect to the vehicle body;
• a first sensor attached to the power unit, for detecting vibration of the power unit;
• a second sensor attached to a suspension member of a suspension system of the automobile, for detecting vibration of the suspension member, said suspension member being displaced relative to the vehicle body in response to movements of wheels of the automobile;
• a third sensor attached to a monitoring point on the vehicle body, for detecting vibration of the vehicle body at the monitoring point;
• and
• control means for controlling said oscillating means, based on a first reference signal and a second reference signal received from said first sensor and said second sensor, respectively, and an error signal received from said third sensor, said control means performing an adaptive control for controlling an operation of the oscillating means, so that said error signal is minimized.
