An electric power steering control apparatus includes a motor that outputs a driving force; and control systems for respectively controlling the motors. Each control system includes a reliability calculation unit that receives an output value from a sensor that detects the state information corresponding to a predetermined detection target provided by the own system, and calculates the reliability of the sensor; a weighted average processing unit that outputs a control signal weighted and averaged on the basis of the reliability in the own system and the output value of the sensor in the own system, and the reliability in the at least one other system and the output value of the sensor in the at least one other system received from the at least one other system; and a motor control unit that generates a drive signal for driving the motor based on the control signal.
