PROBLEM TO BE SOLVED: To provide an active vibration control supporting device capable of controlling not only primary vibration but also higher-order vibration based on primary vibration of a vibration body. SOLUTION: Since an electronic control unit for controlling the active vibration control supporting device estimates a vibration condition of main-order vibration (primary vibration) from fluctuation of rotation of a crank shaft of an engine, retrieves a vibration condition of higher-order vibration (secondary vibration and tertiary vibration) having correlation with the vibration condition of the primary vibration from a map set in advance, and drives an actuator of the active vibration control supporting device by target current calculated based on the vibration condition of the primary vibration and the vibration condition of the higher-order vibration, a necessity for estimating the vibration condition of the higher-order vibration from the fluctuation of rotation of the crank shaft of the engine is eliminated and vibration up to the higher-order vibration is effectively controlled while reducing computing load of the electronic control unit to increase vibration control effect of the active vibration control supporting device.
