Zusammenfassung:An electronically controlled power steering apparatus for controlling the steering assist amount of a steering mechanism of a vehicle is controlled in accordance with a fatigue condition of a driver of the vehicle. The apparatus includes means for setting an aimed assist amount, and means for detecting a degree of fatigue of a steering operator. The aimed assist amount setting means receives, as an input thereto, a value calculated by the fatigue detecting means and sets the aimed assist amount in accordance with a fuzzy rule so that the steering assist amount may increase as the degree of fatigue steering operator increases.
