An object of the present invention is to provide a vehicle steering
apparatus that detects the tire load, and based on the detected tire
load, performs steering control which accurately reflects the road
conditions. A vehicle steering apparatus of the present invention
includes a control unit 14, which controls a steering actuator in
accordance with the operation of a steering wheel 1. An operation
reaction force generated by a reaction force actuator 9 is applied to the
steering wheel. Within the tire W, stress sensors SL and SR and an air
pressure sensor SP are provided. The control unit 14 controls the
steering actuator 2 and the reaction force actuator 9 with referring to
the tire load detected by these sensors.
