ABSTRACT:
A control system and control method for a power steering apparatus includes a vehicle speed sensor for detecting a running speed V of a vehicle and a steering angle sensor for detecting a steering angle ha of the vehicle. It further includes a steering holding degree calculation unit to determine a steering holding coefficient K.sub.S from a steering angular velocity ha', a steering angle changing amount H, and a lateral acceleration G.sub.Y. Finally, a fuzzy logic calculation unit is included for setting a target steering assist amount in accordance with a fuzzy logic rule using the vehicle speed V and a product V.multidot.G.sub.Y of the vehicle speed V and the lateral acceleration G.sub.Y as input conditions (membership functions). Thereby, a steering assist amount in a steering mechanism of the vehicle is controlled to the target steering assist amount the control system and control method of a power steering apparatus can provide an optimum steering characteristic according to the high speed running condition of the vehicle.
