Abstract
A steering control apparatus which controls an amount of assist to a power assist mechanism so as to improve a steering characteristic of a vehicle. A steering torque detecting unit detects a steering torque transmitted to a steering mechanism and outputs a detection signal corresponding to the detected steering torque. An amount of assistance provided to the steering effort is controlled by a control unit based on the detection signal supplied by the steering torque detecting unit. The detection signal transmitted to the controlling unit is adjusted by an adjusting unit so that a hysteresis characteristic is provided to a relationship between a steering wheel torque applied to a steering wheel and the steering torque transmitted to the steering mechanism.
