Description
Die Erfindung betrifft ein Verfahren zum Betreiben eines Hybridantriebs eines Fahrzeugs, wobei der Hybridantrieb mindestens einen Verbrennungsmotor und mindestens eine elektrische Maschine als Antriebsmaschinen aufweist.The The invention relates to a method for operating a hybrid drive a vehicle, wherein the hybrid drive at least one internal combustion engine and at least one electric machine as drive machines.
Stand der TechnikState of the art
Es ist bekannt, Fahrzeuge mit einem Hybridantrieb anzutreiben. Als Hybridantrieb wird ein Antrieb bezeichnet, der mindestens zwei unterschiedliche Antriebssysteme nutzt. Bekannt sind Hybridantriebe mit mindestens einem Verbrennungsmotor und mindestens einer elektrischen Maschine, wobei die elektrische Maschine motorisch als Elektromotor und/oder generatorisch als Generator betrieben werden kann. Der Elektromotor erhält seine elektrische Energie aus einem Energiespeicher, zum Beispiel einer oder mehrerer Batterien, oder wird mittels eines Generators von der Verbrennungsmaschine erzeugt. Außerdem besitzt das Fahrzeug die Möglichkeit, Bremsenergie in Form elektrischer Energie zurückzugewinnen (Rekuperation). Wird der Hybridantrieb in einem parallelen Betriebsmodus betrieben, bei dem der Abtrieb des Verbrennungsmotors und der Abtrieb der elektrischen Maschine gekuppelt werden können (paralleler Hybridantrieb), kann das Fahrzeug wahlweise vom Verbrennungsmotor, der elektrischen Maschine oder beiden Antriebsmaschinen angetrieben werden. Eine Betriebsstrategie zum Betreiben des Hybridantriebs sorgt dafür, dass die beiden Antriebsmaschinen im jeweiligen Optimum bezüglich eines niedrigen Energieverbrauchs und/oder einer niedrigen Schadstoffemission betrieben werden. Zur Einhaltung eines Emissionsgrenzwertes kann es zum Beispiel notwendig werden, den Verbrennungsmotor, abhängig von einer Temperaturschwelle, einzuschalten, um einen dem Verbrennungsmotor zugeordneten Katalysator auf einer zur Konvertierung notwendigen Betriebstemperatur zu halten, obwohl die Betriebsstrategie einen Betrieb des Hybridantriebs alleine mit der elektrischen Maschine vorsieht. Derart unkoordinierte Maßnahmen verursachen einen unnötig hohen Kraftstoffverbrauch und/oder erhöhen die Schadstoffemission des Hybridantriebs.It is known to drive vehicles with a hybrid drive. When Hybrid drive is called a drive that has at least two different ones Drive systems uses. Are known hybrid drives with at least an internal combustion engine and at least one electric machine, wherein the electric machine is motorized as an electric motor and / or can be operated as generator generator. The electric motor receives his electrical energy from an energy storage, for example one or more batteries, or by means of a generator generated by the internal combustion engine. In addition, the vehicle owns the possibility of braking energy to recover in the form of electrical energy (Recuperation). Will the hybrid drive in a parallel operating mode operated, in which the output of the internal combustion engine and the output the electric machine can be coupled (parallel hybrid drive), the vehicle can optionally from the internal combustion engine, the electric Machine or both prime movers are driven. A Operating strategy for operating the hybrid drive ensures that the two prime movers in the respective optimum with respect to a low energy consumption and / or a low pollutant emission operate. To comply with an emission limit can For example, it may become necessary to use the internal combustion engine, depending on a temperature threshold, turn on to the internal combustion engine associated catalyst on a necessary for conversion Operating temperature, although the operating strategy one Operation of the hybrid drive alone with the electric machine provides. Such uncoordinated measures cause an unnecessarily high Fuel consumption and / or increase the Pollutant emission of the hybrid drive.
Offenbarung der ErfindungDisclosure of the invention
Das erfindungsgemäße Verfahren zum Betreiben eines Hybridantriebs sieht folgende Schritte vor:
- – Ermittlung des Fahrprofils einer Fahrstrecke und
- – Betreiben von Verbrennungsmotor und/oder elektrischer Maschine beziehungsweise von Komponenten und/oder Zusatzaggregaten dieser Antriebsmaschinen in Abhängigkeit von aus der Ermittlung des Fahrprofils gewonnenen Betriebsparametern.
- - Determination of the driving profile of a route and
- Operating internal combustion engine and / or electrical machine or of components and / or auxiliary units of these drive machines as a function of operating parameters obtained from the determination of the driving profile.
Mit der Ermittlung des Fahrprofils wird ein kompletter Satz von aufeinander abgestimmten Betriebsparametern der Antriebsmaschinen sowie deren Komponenten und/oder Zusatzaggregaten ermittelt. Da das Fahrprofil durch im Vorfeld bekannte Informationen über die Fahrstrecke bestimmt wird, können die Betriebsparameter direkt anschließend aus dem ermittelten Fahrprofil gewonnen werden. Diese Betriebsparameter können direkt für den Betrieb des Hybridantriebs genutzt werden oder als Startpunkt einer weiteren Optimierung der Betriebsparameter – zum Beispiel bezüglich eines möglichst geringen Energieverbrauchs und/oder einer möglichst geringen Schadstoffemission – dienen. Der zeitliche Abstand zwischen der Ermittlung des Fahrprofils und der Nutzung der daraus resultierenden Betriebsparameter kann dabei sehr unterschiedlich sein. Das Fahrprofil kann auf einem statischen Datensatz beruhen, der in einem Zeitrahmen von Monaten oder Jahren komplett aktualisiert wird. Diese Datensätze können jedoch bei einem „lernfähigen" Verfahren auch beim letztmaligen Abfahren jeder einzelnen Fahrstrecke aktualisiert werden.With the determination of the driving profile becomes a complete set of successive ones coordinated operating parameters of the drive machines and their Components and / or additional aggregates determined. Because the driving profile determined by previously known information about the route will, can the operating parameters directly from the determined driving profile be won. These operating parameters can be directly for operation used the hybrid drive or as a starting point of another Optimization of the operating parameters - for example with respect to one as low as possible Energy consumption and / or the lowest possible emission of pollutants - serve. The time interval between the determination of the driving profile and the use of the resulting operating parameters can thereby be very different. The driving profile can be on a static record that is complete in a timeframe of months or years is updated. These records can but in an "adaptive" method also in Last departure of every single route to be updated.
Insbesondere ist vorgesehen, dass sich das Fahrprofil aus mindestens einer der Kenngrößen Streckenlänge, Höhenprofil, Position von Kreuzungen und/oder Ampelanlagen, Straßenklasse oder Höhenprofil der Strecke ergibt. Diese Kenngrößen enthalten Informationen, die im Vorfeld eines Abfahrens der Fahrstrecke bekannt sind. Unter der Kenngröße Straßenklassen ist eine Klassifizierung der Straßen (Autobahn, Autostraße, Landstraße, innerstädtischer Verkehr) und damit verbundene Geschwindigkeitsbeschränkungen zu verstehen.Especially is provided that the driving profile of at least one of Characteristics of track length, height profile, Position of intersections and / or traffic lights, road class or height profile the route results. These characteristics contain Information known in advance of a departure of the route are. Under the characteristic road classes is a classification of roads (highway, highway, highway, inner-city Traffic) and related speed limits to understand.
Weiterhin ist vorgesehen, dass die Ermittlung des Fahrprofils durch manuelle Dateneingabe mindestens einer Kenngröße und/oder Messwerterfassung bei einem Abfahren der Fahrstrecke zur Ermittlung mindestens einer Kenngröße und/oder Abruf mindestens einer gespeicherten Kenngröße erfolgt. Die Kenngrößen zur Ermittlung des Fahrprofils können zum Beispiel vollständig manuell eingegeben werden. Alternativ können die Kenngrößen – zum Beispiel durch Angabe von Start- und Zielparametern – aus einem abgespeicherten Kennfeld von Kenngrößen abgerufen werden. Durch eine Messwerterfassung bei einem Abfahren der Fahrstrecke können weitere, ergänzende Kenngrößen erfasst werden oder durch Datenabgleich gespeicherte Kenngrößen korrigiert werden.Farther is provided that the determination of the driving profile by manual Data entry of at least one parameter and / or measured value acquisition when driving down the route to determine at least one Characteristic and / or Polling at least one stored parameter takes place. The parameters for Determination of the driving profile can for example completely entered manually. Alternatively, the parameters can - for example by specifying start and destination parameters - from a stored Map of parameters retrieved become. Through a measured value acquisition when driving off the route can more, supplementary Characteristics recorded be corrected or stored by data comparison parameters become.
Nach einer Weiterbildung ist vorgesehen, dass die Ermittlung des Fahrprofils – zumindest teilweise – unter Verwendung eines Navigationssystems erfolgt. Bei einem Navigationssystem wird die Fahrstrecke durch manuelle Dateneingabe aus einem abgespeicherten Datensatz ausgewählt, wobei sich die Kenngrößen aus im Vorfeld bekannten Informationen ergeben. Diese Informationen werden durch eine Messwertaufnahme – zum Beispiel mit GPS (Global Positioning System) – beim Abfahren der Fahrstrecke verifiziert und ermöglichen eine Korrektur der gespeicherten Informationen bei einer Abweichung der tatsächlichen Fahrstrecke von einer gespeicherten Soll-Fahrstrecke. Bei sich wiederholenden Fahrstrecken – zum Beispiel zum Arbeitsplatz – können zusätzliche Kenngrößen, wie zum Beispiel eine Wartezeit im allmorgendlichen Stau, in die Ermittlung des Fahrprofils eingehen.According to a development it is provided that the determination of the driving profile - at least partially - using a navigation system. In a navigation system, the route is selected by manual data input from a stored record, the characteristics of known in advance information result. This information is verified by a measured value recording - for example, GPS (Global Positioning System) - when driving the route and allow a correction of the stored information in a deviation of the actual route from a stored target route. In the case of repetitive routes - for example to the workplace - additional parameters, such as a waiting time in the morning traffic jam, can be included in the calculation of the driving profile.
Mit Vorteil ist vorgesehen, dass die gespeicherte Kenngröße nach Abgleich mit dem ermittelten Fahrprofil dynamisch geändert wird. Dabei können Änderungen des Fahrprofils, wie zum Beispiel zusätzlich Stopps durch Baustellen, beim Abfahren der Fahrstrecke ermittelt und gespeichert werden und stehen somit zur Bestimmung der Betriebsparameter für ein zukünftiges Befahren dieser Fahrstrecke zur Verfügung.With Advantage is provided that the stored characteristic after Adjustment with the calculated travel profile is changed dynamically. It can make changes the driving profile, such as additional stops at construction sites, determined when driving the route and stored and stand Thus, to determine the operating parameters for a future driving on this route to disposal.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass mindestens eine der Komponenten und/oder Zusatzaggregate ein Katalysator des Verbrennungsmotor und/oder ein elektrischer Speicher der elektrischen Maschine ist/sind. Zur Einhaltung zum Beispiel von Emissionsvorschriften kann es notwendig werden, den Verbrennungsmotor abhängig von einer Temperaturschwelle einzuschalten, sodass der Katalysator auf einer zur Konvertierung notwendigen Betriebstemperatur gehalten wird, obwohl die elektrische Maschine allein das zur Fahrt notwendige Moment bereitstellen könnte. Aus dem Fahrprofil wird eine Vorlaufzeit des Verbrennungsmotors als Betriebsparameter bestimmt, aus der sich die Aufheizzeit des Katalysators ergibt. Des weiteren lässt sich aus dem Fahrprofil eine Ladestrategie für den elektrischen Speicher (zum Beispiel eine Batterie) im vorhinein ermitteln. Dabei ergeben sich die Betriebsparameter direkt aus den Kenngrößen der Fahrstrecke. Das Aufladen des elektrischen Speichers kann dabei zum Beispiel im laufenden Betrieb durch den Verbrennungsmotor oder durch Rekuperation erfolgen.To a development of the invention is provided that at least one of the components and / or additional units a catalyst of the internal combustion engine and / or an electrical memory of the electrical machine is / are.

Out The driving profile is a lead time of the engine as an operating parameter determines, which results in the heating of the catalyst. Furthermore, can be from the driving profile a charging strategy for the electrical storage (for example, a battery) in advance to determine. In doing so result the operating parameters directly from the characteristics of the route. The charging of the electrical storage can, for example, while running Operation by the internal combustion engine or by recuperation done.
Weiterhin ist vorgesehen, dass aus dem Fahrprofil eine Betriebsstrategie mit mindestens einem möglichen Betriebsmodus und/oder mindestens einer Kombination möglicher Betriebsmodi und deren zeitliche Abfolge vorgegeben werden. Die Betriebsstrategie verfolgt dabei ein vorgegebenes Ziel, wie zum Beispiel das Unterschreiten eines Emissionsgrenzwertes.Farther is provided that the driving profile with an operating strategy at least one possible Operating mode and / or at least one combination possible Operating modes and their timing are specified.

Der verbrennungsmotorische Betrieb und der elektromotorische Betrieb sind durch einen Antrieb unter Verwendung des Verbrennungsmotors beziehungsweise der elektrischen Maschine als Elektromotor gekennzeichnet. Bei dem elektrogeneratorischen Betrieb wird der elektrische Speicher über einen Generator oder die als Generator wirkende elektrische Maschine aufgeladen. Das Drehmoment für den elektrogeneratorischen Betrieb liefert dabei zum Beispiel der Verbrennungsmotor oder ein Verzögerungsdrehmoment beim Abbremsen des Fahrzeugs. Ist das Fahrprofil durch aufeinanderfolgendes Anfahren und Abbremsen gekennzeichnet, so wird vorzugsweise der Start/Stopp-Betrieb gewählt, bei dem der Verbrennungsmotor in einer Stopp-Phase ausgeschaltet und beim Anfahren wieder gestartet wird.Especially it is provided that at least one of the operating modes is an internal combustion engine Operation, an electromotive operation, an electrogenerator Operation or a start / stop operation of the hybrid drive is.
