A reaction control system controls a reactive force to be applied to an
operating device operated by a driver of a vehicle. The system includes a
device for measuring a steering speed of steering of the operating
device; a device for measuring a steering torque applied to the operating
device; and a reactive force correcting device for correcting the
reactive force in a manner such that the corrected reactive force
increases at least when the measured steering speed is zero, and that the
higher the measured steering torque, the higher the corrected reactive
force is. The reactive force correcting device may correct the reactive
force in a manner such that the higher a speed of the vehicle, the higher
the corrected reactive force is. A non-effectivity range of the steering
torque in which the corrected reactive force is not influenced by the
steering torque may be defined.
