Abstract

Bei einem Verfahren zum Detektieren von sich einem Überwachungsbereich nähernden Fahrzeugen werden die Ausgangssignale mindestens eines zum Empfang der Fahrzeuggeräusche im Überwachungsgebiet ausgelegten Sensors signaltechnisch aufbereitet und bezüglich fahrzeuggeräuschspezifischer Merkmale analysiert, und bei Auffinden solcher Merkmale wird ein eine Fahrzeugdetektion anzeigendes elektrisches Detektions- oder Wecksignal ausgegeben. Zwecks Schaffung eines vollautonom ablaufenden Detektionsverfahrens mit großer Detektionswahrscheinlichkeit und geringer Falschalarmrate wird die Signalanalyse mit mehreren voneinander unabhängigen Weckstufen nach qualitativ unterschiedlichen Merkmalen durchgeführt und in jede Weckstufe nach Extrahieren eines solchen Merkmals mit ausreichender Konfidenz ein Slave-Wecksignal generiert. Die Slave-Wecksignale der einzelnen Weckstufen werden zu einem das Detektions oder Wecksignal darstellenden Master-Wecksignal verknüpft.
