Abstract

A steering control device for a vehicle controls a steering device having a steering mechanism and a drive unit configured to provide the steering mechanism with steering force for the wheels. The steering control device includes a detection unit to detect the steering angle; and a control unit to calculate a target value of a current to be supplied to the drive unit as a current command value, and execute automatic steering control to automatically control steering of the vehicle by causing the drive unit to be supplied with the current of the current command value. When an absolute value of the steering angle comes to a predetermined first threshold or more during the automatic steering control, the control unit decreases an upper limit value of an absolute value of the current command value as the absolute value of the steering angle increases.
