A steering system for a vehicle, includes a control operated by a driver
of the vehicle; a measuring device for measuring a quantity of operation
of the control by the driver; a steering section including a steering
actuator for steering wheels which are mechanically independent of the
control; a section for setting a target steering angle in accordance with
the quantity of operation measured by the measuring device; a reaction
actuator for applying a steering reactive force to the control; a section
for setting a virtual steering angle based on a virtual model which
represents predetermined dynamic characteristics of the steering section;
and a reaction control section for setting a target reactive force in
accordance with a difference between the target steering angle and the
virtual steering angle, and controlling the reaction actuator based on
the target reactive force.
