Abstract
A steering control system with which a steering angle accurately follows a steering angle command value is provided. An assist command value calculation circuit calculates a first assist component based on a value obtained by adding a basic assist controlled variable with a system stabilization controlled variable. The assist command value calculation circuit includes a pinion angle feedback control circuit that calculates a second assist component by executing angle feedback control based on a deviation between a pinion angle and a final pinion angle command value that is the sum of a pinion angle command value and an ADAS command angle. The assist command value calculation circuit outputs an assist command value based on the first assist component and the second assist component. The assist command value calculation circuit receives a steering torque obtained after the influence of viscosity and inertia is reduced by a steering torque compensation circuit.
