Abstract
The power steering system of this invention has a motor which provides auxiliary torque for the steering shaft to assist in steering. The maximum level of the motor current is varied in response to the mean motor current at predetermined intervals of time so as to regulate the maximum motor current and thereby prevent overheating or burning of the motor when, for example, the steering wheel is held for a long time in an extreme position.
