Patent ID: 7946561

Claim:
An anti-vibration support system for a cylinder-suspendable engine, comprising an active anti-vibration supporting device including an elastic member adapted to receive vibration of the engine; a liquid chamber, wherein at least a portion of a wall surface of said liquid chamber is defined by said elastic member; a movable member adapted to change a volume of said liquid chamber; and an actuator that uses an electromagnetic force to drive said movable member, wherein the vibration of the engine is prevented from being transmitted to a vehicle body frame by controlling a supply of electric current to said actuator, and wherein when an abnormality in an operational state of said active anti-vibration supporting device is detected, if the engine is in a cylinder-suspended state, the cylinder suspension of the engine is prohibited and the engine restored to a state where all cylinders are operating, and if the engine is not in a cylinder-suspended state, switching to the cylinder-suspended state is prohibited.
