ABSTRACT:
An electrically operated power steering system on a motor vehicle having steerable road wheels has an electric motor for generating an assistive torque to assist a manual steering torque generated by a steering wheel. The power steering system has a steering torque detector for detecting the manual steering torque and producing a manual steering torque signal, a steering angle detector for detecting a steering angle for the motor vehicle and producing a steering angle signal, a target steering torque signal generator for generating a target steering torque signal based on the steering angle signal, and a motor drive signal generator for generating a motor drive signal to be supplied to the electric motor based on the difference between the target steering torque signal and the manual steering torque signal.
