Original Abstract Submitted
A pedal device includes a pedal lever, an actuator, and a control unit. The pedal lever operates in response to a pedal operation. The actuator can apply a reaction force that is a force in a direction of returning the pedal lever by driving a motor. The control unit includes a current command calculation section that calculates a current command value based on a reaction force target value related to a reaction force applied to the pedal lever and a duty calculation section that calculates a duty command value based on the current command value, and controls a drive of a motor based on the duty command value. The duty calculation section corrects the duty command value based on at least one of a motor current supplied to the motor and a rotation speed of the motor.
