ABSTRACT:
A control apparatus for a power steering system has a travel condition data memory, a plurality of vehicle velocity response data memories, a correction data memory, and a driver. Traveling condition data is read out in response to average vehicle velocity data and average steering angle data. Vehicle velocity response data is read out from one of the vehicle velocity response data memories in response to the traveling condition data and instantaneous vehicle velocity data. The vehicle velocity response data is added by the driver to the correction data from the correction data memory. The corrected vehicle velocity response data is used to drive a control valve, thereby obtaining an optimal steering force.
