Abstract
A solenoid driving device with excellent electric power efficiency which drives and controls an actuator including a solenoid and an active vibration damping support device with excellent electric power efficiency which includes the solenoid driving device are disclosed. The solenoid driving device includes a booster circuitwhich boosts a battery voltage, and driving circuitsA,B which an actuator with the electric power supplied and boosted by the booster circuit. ACM_ECUA including a micro computercalculates the magnitude of the vibration of the engine, an engine vibration cycle and a phase lag to obtain the drive frequency fof the actuator in the vibration state estimating unitand the phase detecting unit. A booster circuit controlling unitof the micro computerdetermines the target voltage V based on the drive frequency f. The target voltage V is input to the booster circuit, and the booster circuitsupplies the required electric power to the driving circuitsA,B at the target voltage V*.
