Abstract
A steering apparatus for a vehicle comprising a calculating means for calculating a target value for the reaction force torque on the basis of a self-aligning torque term which is based on a detected value of a vehicle speed and a detected value of an actual moved position of a steering mechanism, an elastic resistance torque term which is proportional to a deviation between a detected value of the steering operating angle of a steering operating means mechanically not connected to the steering mechanism and a detected value of the actual moved position, and an inertial resistance torque term which is proportional to a time varying amount of the deviation, and the reaction force of the steering operating means is controlled by driving a reaction force motor on the basis of the calculated target value.
