Abstract

Bei einem System zum Beheben der Abweichung des Istwinkels einer verstellbaren, insbesondere kontinuierlich verstellbaren Nockenwelle (15) von einem vorgebbaren Sollwinkel (ϕSoll) im Leerlauf eines Motors (9), wobei eine Steuer- oder Regeleinrichtung zum Steuern oder Regeln der Nockenwellenposition und eine Steuereinheit zur Motorsteuerung vorgesehen ist, ist eine Einrichtung (1) zum Anheben der Leerlaufdrehzahl des Motors (9) vorgesehen, die bei Überschreiten eines vorgebbaren Wertes (SW) der Abweichung des Istwinkels (ϕIst) der Nockenwelle (15) vom vorgebbaren Sollwinkel (ϕSoll) aktivierbar ist. Bei einem Verfahren zur Ansteuerung einer verstellbaren, insbesondere kontinuierlich verstellbaren Nockenwelle (15) eines Verbrennungsmotors (9), die mit einer Steuer- oder Regeleinrichtung zum Steuern oder Regeln der Nockenwellenposition versehen ist, wird bei Überschreiten eines vorgebbaren Wertes (SW) der Abweichung des Istwinkels (ϕIst) der Nockenwelle (15) vom vorgebbaren Sollwinkel (ϕSoll) eine Einrichtung (1) zum Beheben der Abweichung aktiviert und wirkt die Einrichtung (1) auf eine Steuereinheit zur Steuerung des Motors (9) dahingehend ein, dass die Leerlaufdrehzahl erhöht wird.

In a system for correcting the deviation of the actual angle of an adjustable, in particular continuously adjustable camshaft (15) from a predeterminable desired angle (φ Soll) during idling of an engine (9), wherein a control or regulating device for controlling or regulating the camshaft position, and a control unit To control the engine, a device (1) is provided for increasing the idle speed of the engine (9), which, when a predeterminable value (SW) of the deviation of the actual angle (ϕ actual ) of the camshaft (15) from the predefined target angle (ϕ target ) is exceeded ) can be activated. In a method for controlling an adjustable, in particular continuously adjustable camshaft (15) of an internal combustion engine (9), which is provided with a control or regulating device for controlling or regulating the camshaft position, the deviation of the actual angle is exceeded when a predeterminable value (SW) is exceeded (If φ) of the camshaft (15) from the predetermined target angle (φ Soll) means (1) is activated to correct the deviation, and means (1) to a control unit for controlling the motor (9) acts to a that the idling speed increases becomes.
