PURPOSE: A method for correcting detection signals of an angular sensor is provided to eliminate a first offset voltage generated in a hole element according to ambient temperature, thereby improving the measurement accuracy of a minute angle. CONSTITUTION: A method for correcting detection signals of an angular sensor is as follows. A constant current is supplied to an angle detecting sensor in the state of non-magnetic field while offline. First offset voltage values generated by inner resistance caused by the ambient temperature of the angle detecting sensor are respectively measured and temperature properties of the first offset voltage are measured. The ambient temperature is measured by a temperature detecting sensor when measuring an angle while online. A correction eliminating the first offset voltage values corresponding to the temperature properties obtained from outputs of the angle detecting sensor is performed.
