Aufgabe der Erfindung ist es, ein Sensorsystem für ein Fahrzeug anzugeben, mit dem trotz einfachen Aufbau eine Mehrzahl von Größen zur Regelung eines Verbrennungsmotors aufnehmbar sind.task The invention is to provide a sensor system for a vehicle, with despite a simple structure a plurality of sizes for controlling an internal combustion engine are receivable.
Die Erfindung löst diese Aufgabe durch Bereitstellung eines Sensorsystems für ein Fahrzeug mit den Merkmalen des Patentanspruchs 1.The Invention solves this object by providing a sensor system for a vehicle with the features of claim 1.
Vorteilhafte Ausführungsformen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.advantageous embodiments and further developments of the invention are specified in the dependent claims.
Erfindungsgemäß detektiert ein Aufnehmer eines Sensorsystems für ein Fahrzeug zusätzlich zur Erfassung einer Kraftstoffeinspritzmenge in einen Verbrennungsmotor auch das Verbrennungsgeräusch, welches von einer Auswerte- und Steuereinheit ausgewertet wird. Da der Aufnehmer sowohl die Einspritzmenge als auch das Verbrennungsgeräusch erfasst, kann in vorteilhafter Weise auf einen zusätzlichen Klopfsensor verzichtet werden.Detected according to the invention a sensor of a sensor system for a vehicle in addition to the detection a fuel injection amount in an internal combustion engine, too Combustion noise, which is evaluated by an evaluation and control unit. Since the transducer detects both the injection quantity and the combustion noise, can advantageously be dispensed with an additional knock sensor become.
In Ausgestaltung des Sensorsystems ermittelt die Auswerte- und Steuereinheit die Kraftstoffeinspritzmenge aus Strömungsgeräuschen, die vom Aufnehmer aufgenommen werden.In Configuration of the sensor system determines the evaluation and control unit the amount of fuel injection from flow noise picked up by the transducer become.
Alternativ ermittelt die Auswerte- und Steuereinheit die Kraftstoffeinspritzmenge aus einem vom Aufnehmer aufgenommen Nadelhub einer Einspritzdüse.alternative the evaluation and control unit determines the fuel injection quantity from a needle lift of an injection nozzle received by the pickup.
