Abstract

The invention provides a ethod for detecting fast total blockage of a sensor, comprising the steps of collecting and storing information concerning the numbers of targets and objects detected by the sensor, the number of objects created, and the number of objects lost within the detection field of the sensor in each detection cycle over a predetermined time window (T), splitting the time window (T) into a first partition (R), a second partition (O), and third partition (D), determining a first performance indicator based on the number of targets detected in the first partition (R) of the time window (T), a second performance indicator based on the number of targets detected in the third partition (D) of the time window (T), and a degradation indicator based on the number of objects lost within the detection field of the sensor during the second partition (O) of the time window (T); and determining that a fast total blockage event has happened if the first performance indicator shows detection performance typical for the sensor, the degradation indicator shows a fast degradation of detection performance, and the second performance indicator shows detection performance untypical for the sensor.
