Abstract
A steering apparatus includes left and right swing arm members, left and right tie rods pivotally attached to the arm portions of the swing arm members at their inner ends, relay rods pivotally attached to the arm portions at both ends, and a steering input transmission system. Rack-and-pinion type electric power steering devices are connected to the arm portions of the left and right swing arm members. A control unit calculates correcting steering torques for reducing rotational vibrations generated in the electric power steering devices due to a disturbance, and correct target steering assist torques calculated based on a steering torque with the correcting steering torques and control the electric power steering devices with the corrected target steering assist torques.
