Abstract
Tire-uniformity components may generate a lateral force on a vehicle body, when the vehicle is in a turning movement. The lateral force may cause vibrations on the vehicle body. The controller controls a motor of an electric power steering system to modulate an assist torque acting on steerable wheels in accordance with the tire-uniformity components. The assist torque is modulated in the same direction as the lateral force. As a result, it is possible to reduce vibrations on the vehicle body, since the modulated assist torque avoids conflict with the lateral force and release the lateral force.
