Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zu Grunde, ein neuartiges Verfahren zum Betreiben eines Kraftfahrzeugs sowie eine neuartige Steuerungseinrichtung zu schaffen. On this basis, the present invention based on the object to provide a novel method for operating a motor vehicle and a novel control device.
Diese Aufgabe wird durch eine Steuerungseinrichtung eines Kraftfahrzeugs gemäß Patentanspruch 1 gelöst. This object is achieved by a control device of a motor vehicle according to claim 1.
Erfindungsgemäß steuert die Steuerungseinrichtung zur Funktionsüberprüfung der Zusatzpumpe des Hydrauliksystems bei stillstehendem Hybridfahrzeug, bei stillstehendem Verbrennungsmotor des Antriebsaggregats und bei geöffneter Kupplung zunächst die elektrische Maschine des Antriebsaggregats so an, dass dasselbe mit einer Drehzahl betrieben wird, die größer als Null jedoch kleiner als eine zum Betreiben der Hauptpumpe erforderliche Grenzdrehzahl ist, wobei die Steuerungseinrichtung anschließend bei dieser Drehzahl der elektrischen Maschine die zwischen den Verbrennungsmotor und die elektrische Maschine geschaltete Kupplung definiert in Schließrichtung ansteuert und hierbei eine Drehzahl des Verbrennungsmotors und/oder ein Moment der elektrischen Maschine überwacht, wobei dann, wenn die Steuerungseinrichtung hierbei feststellt, das die Drehzahl des Verbrennungsmotors und/oder das Moment der elektrischen Maschine ansteigt, die Steuerungseinrichtung auf eine funktionsfähige Zusatzpumpe schließt, wohingegen dann, wenn die Drehzahl des Verbrennungsmotors und/oder das Moment der elektrischen Maschine nicht ansteigt, die Steuerungseinrichtung auf eine nicht funktionsfähige Zusatzpumpe schließt. According to the invention controls the control device for checking the function of the auxiliary pump of the hydraulic system with a stationary hybrid vehicle, with the internal combustion engine of the drive unit and with the clutch first, the electric machine of the drive unit so that it is operated at a speed greater than zero but less than one to operate The main pump required limit speed is, the control device then controls at this speed of the electric machine, the clutch connected between the engine and the electric machine defined in the closing direction and in this case monitors a speed of the internal combustion engine and / or a moment of the electric machine, in which case the control device determines that the speed of the Increase internal combustion engine and / or the torque of the electric machine, the controller closes on a functioning auxiliary pump, whereas, when the speed of the internal combustion engine and / or the torque of the electric machine does not rise, the controller closes on a non-functional auxiliary pump.
Die hier vorliegende Erfindung ermöglicht die Überprüfung der Funktionsfähigkeit der Zusatzpumpe eines Hydrauliksystems eines Hybridfahrzeugs ohne teuren Drucksensor. The present invention makes it possible to check the functionality of the auxiliary pump of a hydraulic system of a hybrid vehicle without expensive pressure sensor.
Nach einer vorteilhaften Weiterbildung steuert die Steuerungseinrichtung dann, wenn dieselbe auf eine nicht funktionsfähige Zusatzpumpe schließt, die elektrische Maschine derart an, dass deren Drehzahl bei stillstehendem Verbrennungsmotor mindestens der zum Betreiben der Hauptpumpe erforderlichen Grenzdrehzahl entspricht. Mit dieser Ersatzmaßnahme kann dann, wenn auf eine nicht funktionsfähige Zusatzpumpe erkannt wird, über die Hauptpumpe ein ordnungsgemäßer Betrieb des Hybridfahrzeugs aufrechterhalten werden. According to an advantageous development, the control device then, if the same includes a non-functional auxiliary pump, controls the electric machine such that its speed when the engine is stationary at least corresponds to the required for operating the main pump limit speed. With this replacement measure, when a non-functioning auxiliary pump is detected, proper operation of the hybrid vehicle can be maintained through the main pump.
Vorzugsweise steuert die Steuerungseinrichtung zur Funktionsüberprüfung der Zusatzpumpe das Getriebe derart an, dass das Getriebe zum Abtrieb hin in Neutralstellung ist und demnach zum Abtrieb kein Moment überträgt. Hierdurch wird sichergestellt, dass das Hybridfahrzeug bei der Funktionsüberprüfung der Zusatzpumpe nicht anfährt. Preferably, the control device controls the function of the auxiliary pump, the transmission in such a way that the transmission to the output is in neutral position and therefore transmits to the output no moment. This ensures that the hybrid vehicle does not start when checking the function of the auxiliary pump.
Nach einer vorteilhaften Weiterbildung betreibt die Steuerungseinrichtung zur Funktionsüberprüfung der Zusatzpumpe die elektrische Maschine drehzahlgeregelt. Der drehzahlgeregelte Betrieb der elektrischen Maschine zur Funktionsüberprüfung der Zusatzpumpe ist bevorzugt. According to an advantageous development, the control device operates to control the function of the auxiliary pump, the electric machine speed controlled. The speed-controlled operation of the electrical machine for functional testing of the auxiliary pump is preferred.
