Abstract
Description
Die Erfindung betrifft eine Steuerungseinrichtung eines Kraftfahrzeugs nach dem Oberbegriff des Anspruchs 1. Des Weiteren betrifft die Erfindung ein Verfahren zum Betreiben eines Hydrauliksystems eines Kraftfahrzeugs nach dem Oberbegriff des Anspruchs 6. The invention relates to a control device of a motor vehicle according to the preamble of

Es besteht daher Bedarf an einer Steuerungseinrichtung für ein Kraftfahrzeug sowie an einem Verfahren zum Betreiben eines Antriebsstrangs eines Kraftfahrzeugs, mit welchem diese Probleme vermieden werden können. Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zu Grunde, eine neuartige Steuerungseinrichtung eines Kraftfahrzeugs sowie ein neuartiges Verfahren zum Betreiben eines Hydrauliksystems eines Kraftfahrzeugs zu schaffen. There is therefore a need for a control device for a motor vehicle and a method for operating a drive train of a motor vehicle, with which these problems can be avoided. On this basis, the object of the present invention is to provide a novel control device of a motor vehicle and a novel method for operating a hydraulic system of a motor vehicle.
Diese Aufgabe wird durch eine Steuerungseinrichtung nach Anspruch 1 gelöst. Hiernach steuert die Steuerungseinrichtung nach Auftreten des Fehlers und Veranlassen der Ersatzmaßnahme die Zusatzpumpe erst dann wieder zur Bereitstellung einer Hydraulikdruckanforderung an, wenn einerseits der Fehler der Zusatzpumpe nicht mehr vorliegt und wenn andererseits nach dem Verschwinden des Fehlers die Einschaltbedingung für die Zusatzpumpe zumindest einmal nicht erfüllt war. Mit der Erfindung ist es möglich, Probleme der Praxis zu vermeiden. So wird ein unerwünschtes, häufiges Hin- und Herwechseln in der Hydraulikversorgung vermieden. Hierdurch können mechanische Anregungen des Antriebsstrangs und akustische Beeinträchtigungen vermieden werden. This object is achieved by a control device according to
Das erfindungsgemäße Verfahren zum Betreiben eines Hydrauliksystems eines Kraftfahrzeugs ist in Anspruch 6 definiert. The inventive method for operating a hydraulic system of a motor vehicle is defined in claim 6.
