PURPOSE: An error controlling method of the hall sensor signal is provided to determine the existence of error of the received hall sensor signal based on the previous hall sensor signal and pre-defined signal pattern, thereby control the rotation of the motor. CONSTITUTION: A hall sensor signal is received from the hall sensor(100). Based on the hall sensor signal, whether the rotation of the motor is made within the predetermined normal range is determined. The hall sensor senses the rotator position of the motor in the electronic control unit(200). If a pattern consisting of the hall sensor signal is not included in the pre-defined signal pattern within the normal range, previously stored error list is determined. The rotation of the motor is controlled by the existence of the error list.
