In a steering mechanism of steer-by-wire type which includes a first steering unit that is handled by a driver and a second steering unit that steers steered road wheels with the aid of a steering motor, there is employed a control system which input and output detecting sections that detect input and output of the steering motor, a road surface disturbance estimating section that estimates a disturbance of road surface based on both the detected input and output of the steering motor, and a steering reaction force calculating section that, based on the estimated disturbance of road surface, calculates a steering reaction force that is to be applied to a steering wheel of the first steering unit.
