PROBLEM TO BE SOLVED: To provide an electric power steering control device capable of easily and accurately determining the abnormality of a steering angle information detection means by using only parameters directly reflecting the actual rotating operation of a steering mechanism. SOLUTION: This electric power steering control device comprises a steer angle information detection means 16 detecting the steer angle information Vs of the steering mechanism, a controller generating a motor current according to the steer angle information and the magnitude and direction of a steering torque, an electric motor mechanically connected to the steering mechanism to generate a steering assist torque according to the motor current in the steering wheel, a motor rotation information detection means 101 detecting the rotation information Vm of the electric motor, and an abnormality determination means 17A determining that the steer angle information detection means 16 is abnormal when a deviationΔV between motor rotation information Vm and steer angle information Vs shows a standard reference valueαor higher.
