1. An electric power steering control apparatus comprising:

  • a steering torque detection section that detects steering torque generated by a driver of a vehicle;

    a motor that generates assist torque in accordance with said steering torque;

    a motor angular velocity detection section that detects the angular velocity of said motor;

    a specific frequency detection section that detects the frequency of a steering vibration generated due to the structure of said vehicle;

    a phase compensation section that converts the phase of said motor angular velocity based on a detected value of said motor angular velocity; and

    a vibration suppression current calculation unit that calculates a steering vibration suppression current for suppression of said steering vibration based on the respective output signals of said specific frequency detection section and said phase compensation section.
