Method for evaluating signal from sensor, involves comparing signal with threshold value and increasing value of error counter by error integral, if signal value exceeds threshold value

摘要

The method involves comparing a signal (11) with a threshold value (18) and increasing value of an error counter (15) by an error integral, if the signal value exceeds the threshold value. The error counter is reset gradually, when the signal value decreases below the threshold value or the signal value reaches zero. An error condition (34) is set, when the error counter reaches an error threshold.
