PURPOSE: An actuator driving apparatus is provided to accurately drive an actuator depending on a duty signal by removing residual current of the actuator through control of the duty signal outputted from a control unit via a driving drive. CONSTITUTION: An actuator driving device comprises a vehicle data detecting unit(10), a control unit(20), a driving drive(30) and an actuator(40). The vehicle data detecting unit detects general data obtained during stoppage and travel of the vehicle and outputs corresponding electrical signals. With the electrical signals, a logic unit of the driving drive performs logic operation. Supply power determined by a signal applied from the logic unit is supplied to the actuator by a driving voltage application unit of the drive. A driving voltage control unit having an N-channel MOSFET for removal of residual currents outputs an electrical signal for accurate control of the motion of the actuator. According to accurate control of the actuator due to removal of residual currents via duty signals, reliability and safety are realized.
