A power steering apparatus has a steering power assisting system coupled to tire wheels and a variable gear transfer system coupled to a steering wheel. The steering power assisting system includes a torsion bar rotation sensor and a first actuator rotation sensor to calculate a first pinion angle and a second pinion angle based on the detected rotation angles, respectively. The variable gear transfer system includes a steering sensor and a second actuator rotation sensor to calculate a third pinion angle based on the detected rotation angles. Sensor failure is detected by comparing the calculated first, second and third pinion angles.

A driving support apparatus of a vehicle supports driving of the vehicle, the vehicle includes a rudder angle varying device capable of changing a relative relation between a steering angle and a rudder angle. The driving support apparatus includes a following control device for controlling the rudder angle varying device such that the vehicle follows a target driving route; a steering angle specifying device for specifying the steering angle; and a judging device for judging whether or not overriding performed by a driver takes place on the basis of the specified steering angle and a reference steering angle which is the steering angle in making the vehicle follow the target driving route. The following control device stops the vehicle following for the target driving route if it is judged that the overriding takes place.
