Abstract

A steering control system that maintains the follow-up accuracy with which a steering angle follows a steering angle command value is provided. An assist command value calculation circuit (43) calculates a first assist component (Ta1*) based on a value obtained by adding together a basic assist controlled variable (Tas*) and a system stabilization controlled variable (Tdt*). The assist command value calculation circuit (43) includes a pinion angle feedback control circuit (60) that calculates a second assist component (Ta2*) by executing angle feedback control based on a deviation between a pinion angle (¸p) and a final pinion angle command value that is the sum of a pinion angle command value and an ADAS command angle (¸a*). The assist command value calculation circuit (43) outputs an assist command value (Ta*) based on the first assist component (Ta1*) and the second assist component (Ta2*). The assist command value calculation circuit (43) receives a steering torque (Th) obtained after the influence of viscosity and inertia is reduced by a steering torque compensation circuit (80).
