To obtain a steering control device that prevents fluctuation of target current for electric power assist based on inertia torque acting on a steering wheel during automatic steering, allows for smooth automatic steering control, and smoothly assists a driver in steering during automatic steering control. The device includes an electric power assist control unit (71) that calculates a target electric-power-assist current of a motor for electric power assist control, an automatic steering control unit (72) that calculates a target automatic-steering current of a motor for automatic steering control of steered wheels, a current control unit (73) that controls motor current in accordance with the sum of the target electric-power-assist current and the target automatic-steering current during automatic steering control, and a frequency component extractor (711) that extracts a predetermined frequency component which includes a driver steering frequency of the target electric-power-assist current and does not include a frequency of a fluctuation component caused by the inertia torque acting on the steering wheel, and corrects the target electric-power-assist current using the extracted frequency component. |
