Das Motorsteuergerät 14 steuert anhand dieser Position, sowie ggf. weiterer Bedingungen, wie beispielsweise Fahrzeuggeschwindigkeit, Gang, Motorlast, Motordrehzahl usw., eine oder mehrer Abgasklappen 42, die dann die Motorakustik beeinflussen. Beispielsweise wird die Geräuschentwicklung des Motors durch Veränderung der Stellung wenigstens einer Abgasklappe reduziert und/oder die Geräuschentwicklung in Richtung eines sportlicheren Höreindrucks für Fahrer und Passagiere verändert.According to the invention, the engine acoustics are influenced as a function of the position of the convertible top 12 (open or closed). For this purpose, the top position is determined via the sensor 16 and forwarded to the engine control unit 14. The engine control unit 14 controls based on this position, and possibly other conditions such as vehicle speed, gear, engine load, engine speed, etc., one or more exhaust valves 42, which then affect the engine acoustics. For example, the noise of the engine is reduced by changing the position of at least one exhaust valve and / or changes the noise in the direction of a sportier auditory impression for drivers and passengers.
Die Abgasklappen 42 werden elektrisch (Fig. 3) oder elektro-pneumatisch (Fig. 2) oder auf andere geeignete Weise angesteuert. Die Steuerung erfolgt innerhalb des Motorsteuergerätes 14 beispielsweise über ein Bit. Dieses Bit schaltet Spannung bzw. Masse auf einen Motorsteuergeräte-Ausgangs-PIN 32, der mit dem elektro-pneumatischen Steuerventil 34 der Abgasklappe(n) verdrahtet ist, wie aus Fig. 2 ersichtlich, oder indirekt verbunden ist. Alternativ wäre auch eine direkte Ansteuerung über ein elektrisches Ventil 44 möglich, wie aus Fig. 3 ersichtlich. The exhaust flaps 42 are electrically (Fig. 3) or electro-pneumatic (Fig. 2) or controlled in any other suitable manner. The control takes place within the engine control unit 14, for example via a bit. This bit switches voltage or ground to an engine ECU output PIN 32 wired to the electro-pneumatic control valve 34 of the exhaust valve (s), as shown in FIG. 2, or indirectly connected.
