Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Steuerung eines Verbrauchers, insbesondere eines elektromagnetischen Ventils, gemäß des Oberbegriffs des Anspruchs 1.The invention relates to a device to control a consumer, especially an electromagnetic one Valve, according to the generic term of claim 1.
Eine Vorrichtung zur Steuerung eines
Verbrauchers, insbesondere eines elektromagnetischen Ventils, ist
beispielsweise aus der
Werden induktive Lasten geschaltet, so entstehen Spannungsspitzen. Diese werden üblicherweise mittels Widerständen, Dioden und/oder Kondensatoren in einer Endstufe oder dem Steuergerät gelöscht. Die dabei am Verbraucher entstehende Freilaufspannung gelangt über die Anschlussleitung, z. B. über den Fahrzeugkabelbaum, zur Endstufe im Steuergerät. Dabei führen sie bei der Aktivierung zu Funkstörungen.If inductive loads are switched, this creates voltage spikes. These are usually by means of resistors, diodes and / or capacitors in a power amplifier or the control unit are deleted. The freewheeling voltage that arises at the consumer reaches the Connection cable, e.g. B. about the vehicle wiring harness, to the output stage in the control unit. In doing so, they result in the activation to radio interference.
Vorteile der ErfindungAdvantages of invention
Dadurch, dass die Mittel zum Abbau der Freilaufspannung in räumlicher Nähe zum Verbraucher angeordnet sind, kann die Freilaufspannung bereits an der Quelle, d. h. an dem Verbraucher gelöscht werden. Funkstörungen können sich nicht über die Leitung bzw. den Kabelbaum ausbreiten und werden dadurch erheblich reduziert.Because of the means of dismantling the freewheel voltage in spatial Proximity to Consumer are arranged, the freewheeling voltage can already be on the source, d. H. be deleted at the consumer. Radio interference can occur no over spread the line or the wiring harness and thereby become considerable reduced.
Vorteilhafte und zweckmäßige Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous and expedient configurations and further developments of the invention are characterized in the subclaims.
Zeichnung Die Erfindung wird nachstehend anhand der in der Zeichnung dargestellten Ausführungsform erläutert.DRAWING The invention is described below of the embodiment illustrated in the drawing.
