Abstract
The present invention relates to an actuator apparatus of an active accelerator pedal, which can provide a driver with a pressing-force rise mode or a vibration mode in accordance with the operational condition of the accelerator pedal and the traveling condition of the vehicle; therefore, it is possible to improve fuel efficiency and also help safe traveling. An actuator apparatus of an active accelerator pedal of the present invention includes: an actuator housing fixed to a pedal arm housing; a stator fixed to the actuator housing and electromagnetized by current transmitted though the control of an ECU; a carrier having one end disposed in a stator and the other end disposed toward the pedal arm through the actuator housing, and applying pressing-force to the pedal arm while protruding from the stator when current is applied to the stator; and a position sensor disposed in the actuator housing and detecting the amount of rotation of the pedal arm to determine the amount of current applied to the stator through the control of the ECU.
