Abstract:
To obtain an electric power steering control apparatus hard to generate vibration even when accuracy is not high enough for torque vibration of extremely small output of torque detecting means. An electric power steering control apparatus includes steering torque detecting means, a torque controller that computes an auxiliary torque current, a motor that generates a torque for assisting a steering torque, current steering component removing means for removing a component by steering, vibration velocity estimating means for estimating a vibration velocity in a rotational direction of the motor, and a damping controller that computes a damping current to be added to the auxiliary torque current, and the vibration velocity estimating means includes vibration acceleration computing means for computing vibration acceleration in the rotational direction of the motor by multiplication of a motor current output from the current steering component removing means, and rotational acceleration integrating means for computing the vibration velocity in the motor rotational direction by integrating the vibration acceleration computing means.
