ABSTRACT:
An electric power steering apparatus comprises broken point characteristics determining means for determining a value of a steering torque signal corresponding to a broken point of a broken line function on the basis of a vehicle speed signal from a vehicle speed sensor, a broken line function circuit for determining the broken line function in accordance with the broken point determining signal determined by the broken point characteristics determining means and outputting an analog signal corresponding to the broken line function, and means for determining a target value of a motor current to drive an electric motor for assisting steering on the basis of the analog signal.
