Abstract
A motorized power steering apparatus for a vehicle has a torque sensor including a right turn potentiometer and a left turn potentiometer which generate output voltages corresponding to the steering torque during a right turn or a left turn, respectively. A motor controller controls the output torque of a drive motor which generates an auxiliary steering force corresponding to the output voltage of one of the potentiometers. A logic circuit prevents current from being supplied to the motor when both of the potentiometers generate an output voltage at the same time.
