Abstract

Eine Weckvorrichtung, die auf von Fahrzeugen hervorgerufenen Geräusche anspricht und ein die Anwesenheit solcher Fahrzeuge anzeigendes Wecksignal erzeugt, weist mindestens einen Sensor (10) zum Empfangen der Fahrzeuggeräusche und eine Signalverarbeitung (11) für die elektrischen Ausgangssignale des mindestens einen Sensors (10) auf. Zwecks Schaffung einer Weckvorrichtung mit großer Detektionsreichweite und hoher Detektionswarscheinlichkeit bei geringer Falschalarmrate unter Verzicht auf eine aufwendige Signalverarbeitung weist die Signalverarbeitung mindestens zwei Signalverarbeitungskanäle auf, in denen aus den Ausgangssignalen des mindestens einen Sensors (10) Pegelsignale mit verschiedenen Signaleigenschaften abgeleitet werden und mittels Schätzfilter (16,17) und Entscheidungslogiken (18,19) physikalisch interpretierbare Merkmale aus den Pegelsignalen extrahiert und die Konfidenz der Extraktion bewertet wird. Mit den extrahierten Merkmalen und deren Konfidenzen werden die Schätzfilter (16) bezüglich der Funktionsweise, der einzustellende Funktionsparameter sowie der Entscheidungsschwellen beeinflußt.

Figure 00000001
A wake-up device, which responds to noises caused by vehicles and generates a wake-up signal indicating the presence of such vehicles, has at least one sensor (10) for receiving the vehicle noises and signal processing (11) for the electrical output signals of the at least one sensor (10). In order to create a wake-up device with a large detection range and a high detection probability with a low false alarm rate without the need for complex signal processing, the signal processing has at least two signal processing channels in which level signals with different signal properties are derived from the output signals of the at least one sensor (10) and by means of estimation filters (16 , 17) and decision logics (18, 19), physically interpretable characteristics are extracted from the level signals and the confidence of the extraction is assessed. With the extracted features and their confidence, the estimation filters (16) are influenced with regard to the mode of operation, the function parameters to be set and the decision thresholds.
