Abstract
Description
Die Erfindung betrifft ein Verfahren zur Steuerung der Verzögerungsleistung eines Fahrzeugs nach dem Oberbegriff des Patentanspruchs 1 sowie ein Fahrzeug mit Hybridantrieb nach dem Patentanspruch 5.The invention relates to a method for controlling the deceleration performance of a vehicle according to the preamble of patent claim 1 and a vehicle with hybrid drive according to
Fahrzeuge mit Hybridantrieb können durch im generatorischen Betrieb verwendete elektrische Maschinen während eines Bremsvorganges Energie zurückzugewinnen. Die als Generator verwendete elektrische Maschine wirkt dabei als rekuperative Bremse. Die Nutzung der rekuperativen Bremse ist nicht immer möglich, da zum Beispiel bei vollgeladener Batterie oder bei thermischer Überlastung der elektrischen Maschine keine rekuperative Bremsung mehr möglich ist. Bei Wegfall der rekuperativen Bremsmöglichkeit hat dies eine Änderung des Verzögerungsverhaltens des Fahrzeugs zur Folge.Hybrid drive vehicles can recover energy during a braking operation by electrical machines used in regenerative operation. The electric machine used as a generator acts as a recuperative brake. The use of the recuperative brake is not always possible because, for example, with fully charged battery or thermal overload of the electrical machine no recuperative braking is possible. In the absence of recuperative braking possibility this has a change in the deceleration behavior of the vehicle result.

Die Aufgabe der Erfindung besteht darin, ein Verfahren und ein Fahrzeug mit Hybridantrieb anzugeben, mit dem die Auswirkungen auf die Längsverzögerung bei sich ändernder rekuperativer Bremsleistung möglichst einfach ausgeglichen werden können.The object of the invention is to provide a method and a vehicle with hybrid drive, with which the effects on the longitudinal deceleration with changing recuperative braking power can be compensated as easily as possible.
Die Aufgabe ist bzgl. des Verfahrens durch die Merkmale des Patentanspruchs 1 und bzgl. des Fahrzeugs mit Hybridantrieb mit den Merkmalen des Patentanspruchs 5 gelöst. Bevorzugte Weiterbildungen der Erfindung sind in den Unteransprüchen offenbart.The object is achieved with respect to the method by the features of claim 1 and with respect to the vehicle with hybrid drive with the features of
Gemäß dem kennzeichnenden Teil des Patentanspruchs 1 wird bei dem erfindungsgemäßen Verfahren zur Steuerung der Verzögerungsleistung eines Fahrzeugs die Bremsleistung der Motorbremse des Verbrennungsmotors dosiert aktiviert, sobald eine vorgegebene Verzögerungsleistung von der im Generatorbetrieb befindlichen elektrischen Maschine nicht mehr oder nicht mehr vollständig bereitgestellt werden kann. Dabei ist unter dosierter Aktivierung der Bremsleistung der Motorbremse zu verstehen, dass die Motorbremse nur in dem Umfang der Bremsleistung des Generators überlagert wird, wie dies zur Erreichung der geforderten Gesamtbremsleistung erforderlich ist. Die rekuperative Bremswirkung hat also stets Vorrang, soweit dies sonstige Betriebsparameter zulassen, um eine möglichst hohe Energierückgewinnung beim Bremsvorgang zu erhalten.According to the characterizing part of patent claim 1, in the method according to the invention for controlling the deceleration power of a vehicle, the braking power of the engine brake of the internal combustion engine is dosed activated as soon as a predetermined deceleration power can no longer or no longer be completely provided by the electric machine in generator operation. In this context, metered activation of the braking power of the engine brake should be understood to mean that the engine brake is superimposed only to the extent of the braking power of the generator, as is required to achieve the required overall braking power. The recuperative braking effect has therefore always priority, as far as this allow other operating parameters to obtain the highest possible energy recovery during braking.
Vorzugsweise wird von einer Steuerung beim Bremsvorgang die rekuperative Bremsleistung des Generators auf einen maximalen Wert eingestellt. Jedoch sind dabei weitere Betriebsparameter zu berücksichtigen, beispielsweise ob der Ladezustand der elektrischen Energiespeicher und/oder thermische Belastungen im Generatorbetrieb bereits vorgegebene Grenzwerte erreicht haben. Muss aufgrund von solchen Betriebsparametern eine Reduzierung der regenerativen Bremsleistung vorgenommen werden, kann dies nun erfindungsgemäß durch eine dosierte Aktivierung der Motorbremse ausgeglichen werden.Preferably, the recuperative braking power of the generator is set to a maximum value by a controller during braking. However, further operating parameters are to be taken into account, for example, whether the state of charge of the electrical energy store and / or thermal loads in the generator mode have already reached predetermined limits. If, due to such operating parameters, a reduction of the regenerative braking power has to be carried out, this can now be compensated according to the invention by a metered activation of the engine brake.
Besonders vorteilhaft kann der Anteil der von der Motorbremse ausgeübten Bremsleistung durch eine Steuerung des Kopplungsgrads zwischen Verbrennungsmotor und Generator eingestellt werden. Dabei kann zur Veränderung des Kopplungsgrads eine Steuerung der ohnehin zwischen der elektrischen Maschine und dem Verbrennungsmotor vorhandenen Kupplung erfolgen.Particularly advantageously, the proportion of the brake power exerted by the engine brake can be adjusted by controlling the degree of coupling between the internal combustion engine and the generator. It can be done to change the degree of coupling control of the existing anyway between the electric machine and the engine clutch.
Gemäß einer Weiterbildung der Erfindung kann auch vorgesehen sein, dass die Bremsleistung des Verbrennungsmotors über die Motorsteuerung und somit durch Beeinflussung von Motoreinstellungen, beispielsweise Veränderung der Ventilsteuerung, beeinflusst werden. Dadurch kann ein größerer Bremsleistungsbereich abgedeckt werden.According to one embodiment of the invention can also be provided that the braking power of the engine via the engine control and thus by influencing engine settings, such as change the valve control, are affected. As a result, a larger braking power range can be covered.
Gemäß Patentanspruch 5 wird ein Fahrzeug mit Hybridantrieb vorgeschlagen, bei dem die Antriebswelle des Verbrennungsmotors zur Aktivierung der Motorbremse über eine Koppeleinheit mit variablem Kopplungsgrad mit der Antriebswelle der elektrischen Maschine koppelbar ist. Bevorzugt wird hierbei die ohnehin vorhandene Kupplung zwischen Verbrennungsmotor und elektrischer Maschine als steuerbare Kupplung verwendet. Um ein reduziertes Motorbremsmoment zu übertragen, wird die Kupplung mehr oder weniger stark angelegt und kann, wenn das maximale Motorbremsmoment übertragen werden soll, vollständig geschlossen werden. Der Kopplungsgrad lässt sich somit auf einfache Weise verändern und an die jeweils erforderliche zusätzliche Bremsleistung anpassen.According to
