Abstract: A vibration control system for electric tilt steering including a lower stationary and upper moveable column through which is rotatably passed a steering shaft having a steering wheel attached to an distal end projecting into a cabin of a vehicle, the moveable column being linked in vertically tiltable fashion to the end of the stationary column and the stationary column being fixed to a vehicle body, with tilting movement of the moveable column being driven by an electric motor to adjust a movable column vertical position. The system includes a control signal generating device for detecting control signal having control frequency and phase for attenuating vibration input to the steering based on a signal synchronized with operation of a vehicle engine, and a drive controlling device for controlling the electric motor drive based on the control signal, to give oscillation to the steering for attenuating vibration input to the steering.
