ERROR ANALYSIS IN A SENSOR ARRAY IN RESPECT OF UNSTABLE ERRORS

摘要

According to a method for analyzing a sensor array (2, 8, 9) in respect of unstable errors, wherein the sensor array (2, 8, 9) emits an analog sensor signal (S) according to a measured variable, a number of error events is identified within a given time interval, the sensor signal (S) having a first slope and a second slope for each of the error events. A diagnostic signal (D) is generated according to a cumulative height of the first and/or the second slopes and is compared with a first threshold value (SW1). An error message (F) is generated according to a result of the comparison.
