ABSTRACT:
It is an object of the present invention to provide a steering control system which can be used with a plurality of control modes, thereby reducing the cost. A first control unit of an electric power-steering system detects a reference current i.sub.REF on the basis of a steering torque T detected by a steering torque detecting device S.sub.2 ; searches a gain K.sub.1 on the basis of a vehicle speed v detected by a vehicle speed detecting device, and carries out a feedback control, so that an actual current i of an electric motor detected by a current detecting device is equal to K.sub.1 .times.i.sub.REF. A second control unit added to the first control unit changes the characteristic of the electric power-steering system by changing the steering torque T and the vehicle speed v, to output the changed steering torque T and vehicle speed v to the first control unit.
