Abstract

An electric power steering apparatus is provided which can suppress the difference in steering feel between before and after it is allowed to compute an absolute steering angle and which can improve the steering feel. A basic assist control unit (41) sets a basic assist current value (Ia). An assist gain setting unit (55) sets assist gain (Ga). The assist gain (Ga) is fixed to a lower limit value less than one before it is allowed to compute the absolute steering angle, and is gradually increased from the lower limit value to one and is then fixed to one after it is allowed to compute the absolute steering angle. An assist gain multiplication unit (42) corrects the basic assist current value (Ia) by multiplying the basic assist current value (Ia) by the assist gain (Ga).
