Abstract

Die Erfindung betrifft ein Verfahren zum Betreiben eines Heizelements in einem Kraftfahrzeug durch Pulsweitenmodulation, wobei zum Erzielen einer gewünschten Heizleistung Fluktuationen der Versorgungsspannung durch eine Anpassung des Tastgrads ausgeglichen werden. Erfindungsgemäß ist vorgesehen, dass während eines Spannungspulses ein Summenwert ermittelt wird, der mit der durch den Spannungspuls in das Heizelement einspeisten Energie ansteigt, indem die an dem Heizelement anliegenden Spannung und/oder der durch das Heizelement fließende Strom in vorgegebenen Zeitabständen gemessen werden und die gemessenen Werte oder aus ihnen ermittelte Werte aufsummiert werden, und der Spannungspuls spätestens dann beendet wird, wenn der Summenwert einen Sollwert erreicht hat. Die Erfindung betrifft ferner ein Glühkerzensteuergerät zur Ausführung des erfindungsgemäßen Verfahrens.

The invention relates to a method for operating a heating element in a motor vehicle by pulse width modulation, wherein to achieve a desired heating power fluctuations of the supply voltage can be compensated by adjusting the duty cycle. According to the invention, it is provided that during a voltage pulse, a sum value is ascertained which increases with the energy fed into the heating element by the voltage pulse, by measuring the voltage applied to the heating element and / or the current flowing through the heating element at predetermined time intervals and the measured values Values or values determined from them are summed up, and the voltage pulse is terminated at the latest when the sum value has reached a setpoint value. The invention further relates to a glow plug control device for carrying out the method according to the invention.
