Abstract
Electric power steering apparatus includes a control nit for controlling an electric motor to impart electric steering assist torque to the steering system of an automotive vehicle. The control unit is provided with a non-steady state detector section that generates a modification signal when it detects a non-steady state of the vehicle in which the steering wheel is turned to an excessive extent. Target motor current signal, which acts to impart the electric steering assist torque corresponding to manual steering torque, is modified by the control unit in accordance with the modification signal generated by the non-steady state detector section. Thus, the tire-to-steering-wheel torque is assisted in a returning direction of the steering wheel, so that the steering wheel is allowed to return to its center position at an increased speed.
