Abstract
A smart angular position sensor includes electronic circuitry for automatically compensating for errors in the output signal of the sensor. The electronic circuitry includes an electronic memory for storing predetermined compensation values used to compensate the output signal of the sensor. The predetermined compensation values are determined by comparing the output signal of the sensor with ideal values at predetermined angular positions. The deviation of the actual values relative to the ideal values is used in determining the compensation values. The compensation values are stored in the electronic memory and are used to automatically compensate the output signal of the sensor.
