Abstract
An electrically operated power steering apparatus basically has a steering torque sensor, a steering rotational speed sensor, and preferably a vehicle sensor. A controller outputs a motor control signal based on a steering torque, a steering rotational speed, and a vehicle speed which are detected by the steering torque sensor, the steering rotational speed sensor, and the vehicle sensor, respectively. The motor control signal is applied to control a motor driver to output a motor drive signal which energizes an electric motor to produce an assistive steering force or a braking force. The electrically operated power steering apparatus is effective to improve steering and returning characteristics of a steering system, and give the steering system a stable steering capability.
