The present invention relates to a control device for a steering sensor error which determines and controls sensor errors of a steering device by comparing the steering torque and the angular velocity of the vehicle steering device. The present invention provides a control device for a steering sensor error, which comprises an oscillation circuit outputting a sinusoidal wave signal oscillating around a reference potential; a first differential amplification circuit amplifying the current with the delivered sinusoidal wave signal and detecting the steering torque signal of a steering wheel from the combination of a coil unit and a main resistance unit; a third differential amplification circuit detecting the steering angular velocity signal of the steering wheel with the delivered sinusoidal wave signal and an output signal of a piezoelectric resonator outputting a phase-shifted signal according to the angular velocity of the steering wheel with the delivered sinusoidal wave signal; a first comparator comparing the output signal of the first differential amplification circuit and the output signal of the third differential amplification circuit; and a main control unit determining errors of the steering torque signal and the steering angular velocity signal on the basis of the output of the first comparative circuit. |
