A steering controller sets a steer angle ratio to a high value in a high angle ratio mode that is high relative to a reference value in a normal mode. A control section controls operation of a reaction force motor and a tire turning motor based on a steer angle ratio mode input to a switch. The control section controls an output of the reaction force motor provided for a driver based on (i) a “reaction force amount” based on road surface information calculated from output of the tire turning motor and (ii) a “viscosity compensation amount” negatively correlated with a steering speed of a steering device.
