Electric power steering apparatus

摘要

An electric power steering apparatus wherein a motor driving prohibiting means prohibits driving of a motor (4) when a driving logic determining unit (9) determines that a detected torque is outside a specified range, a direction in which the motor (4) is to be driven on the basis of a motor current target value and the direction of the steering torque are opposite with respect to each other, and the direction in which the motor is to be driven on the basis of the motor current target value and the changed direction detected by the torque changed direction detecting unit (21) are opposite with respect to each other, and when an abnormal current determining unit (6a) detects that a driving current is greater than a specified value. <IMAGE>
