Abstract
An electric power steering apparatus is disclosed in which steering return control is maintained when vehicle speed reaches a predetermined vehicle speed range after the vehicle speed has been lower than the speed range, and steering return control is disabled when the vehicle speed reaches the predetermined vehicle speed range after the vehicle speed has been higher than the speed range and steering angular velocity has been higher than a predetermined value. Therefore, the control state between the steering return control and convergence control can preferably be switched so that the steering wheel settles quickly to a steering angle predetermined point based on the vehicle speed and the steering angular velocity even while the steering state is not changing.
