Die Betriebssteuereinheit 16 ist dazu vorgesehen, zumindest einen Parameter für einen Energieverbrauch der Antriebseinheit 14 optimiert anhand einer vorausschauenden Betrachtung einer Fahrtroute einzustellen. Die Navigationssteuereinheit 20 ist zu einer Bestimmung der Fahrtroute vorgesehen, wobei hierzu die Navigationssteuereinheit 20 über eine herkömmliche Straßenkarte verfügt, die zusätzlich Informationen über eine zulässige Höchstgeschwindigkeit und eine Steigung für die jeweiligen Kanten zwischen den Knotenpunkten der Navigationsdaten enthält. Alternativ zur Steigungsinformation kann auch eine Höhe über einem Meeresspiegel für jeden Navigationspunkt enthalten sein.

Die Antriebseinheit 14 ist von einer Hybridantriebseinheit 18 gebildet und umfasst ein erstes, von einem Verbrennungsmotor gebildetes Antriebsmittel 24 und ein zweites, von einem Elektromotor gebildetes Antriebsmittel 26. Zudem weist das Fahrzeugsystem 10 eine Energiespeichereinheit 28 auf, die einen Akkumulator 30 zur Speicherung elektrischer Energie umfasst. Zu der zumindest teilweisen Steuerung der Antriebseinheit 14 bzw. zu einem Datenaustausch sind die Antriebseinheit 14, die Energiespeichereinheit 28 und die Steuervorrichtung 12 bzw. die Betriebssteuereinheit 16 und die Navigationssteuereinheit 20 mittels eines internen, hier nicht näher dargestellten Bussystems miteinander verbunden, wie beispielsweise mit einem CAN-Bussystem.Operation control unit 16 and a navigation control unit 20. The operation control unit 16 is provided to at least one parameter for energy consumption of Drive unit 14 optimized based on a predictive view of a route set. The navigation control unit 20 is provided for a determination of the travel route, for which purpose the navigation control unit 20 has a conventional road map which additionally contains information about a permissible maximum speed and a gradient for the respective edges between the nodes of the navigation data. As an alternative to the slope information, a height above sea level may also be included for each navigation point. The control device 12 further comprises a memory element 22 in which software of the road map is stored. The drive unit 14 is formed by a hybrid drive unit 18 and comprises a first drive means 24 formed by an internal combustion engine and a second drive means 26 formed by an electric motor.

In Figur 2 ist ein vereinfachter, schematischer Ablauf des Fahrzugssystems 10 dargestellt. Nach einem Starten 34 des Fahrzeugsystems 10 und/oder des Kraftfahrzeugs kann zunächst durch eine Eingabe 36 von einem Bediener des Fahrzeugsystems 10 ein Zielort über die Navigationssteuereinheit 20 eingegeben werden. Sofern der Zielort eingegeben wurde, erfolgt von der Navigationssteuereinheit 20 automatisch eine Berechnung 38 einer möglichen Fahrtroute. Wird kein Zielort von dem Bediener eingegeben, erfolgt eine Erfassung eines Positionsparameters durch die Navigationssteuereinheit 20. Hierbei erfolgt eine Positionserfassung 40 des Kraftfahrzeugs durch Übermittlung eines Positionsparameters an die Navigationssteuereinheit 20 mit Hilfe eines Navigationssatelliten, wie beispielsweise über GPS. Die Übermittlung eines aktuellen Positionsparameters erfolgt hierbei fortlaufend, bis ein Betrieb bzw. eine Fahrt beendet ist. Aus den übermittelten Positionsparametern errechnet die Navigationssteuereinheit 20 weitere Positionsparameter, wie beispielsweise eine aktuelle Bewegungsrichtung bzw. eine Fahrtrichtung, und eine Geschwindigkeit des Kraftfahrzeugs.FIG. 2 shows a simplified, schematic sequence of the vehicle traction system 10. After a start 34 of the vehicle system 10 and / or of the motor vehicle, a destination can be initially input via the navigation control unit 20 by an input 36 from an operator of the vehicle system 10. If the destination has been entered, the navigation control unit 20 automatically performs a Calculation 38 of a possible route. If no destination is entered by the operator, a position parameter is detected by the navigation control unit 20. Here, a position detection 40 of the motor vehicle takes place by transmission of a position parameter to the navigation control unit 20 with the aid of a navigation satellite, for example via GPS. The transmission of a current position parameter is carried out continuously until an operation or a journey is completed. From the transmitted position parameters, the navigation control unit 20 calculates further position parameters, such as a current direction of movement or a direction of travel, and a speed of the motor vehicle.

Anhand der Positionsparameter erfolgt eine Bestimmung einer voraussichtlichen Fahrtroute. Hierbei erfolgt zunächst eine Abfrage 42, ob ein von dem Kraftfahrzeug eingeschlagener Weg bzw. ob der bzw. die Positionsparameter mit einem gespeicherten Streckenparameter einer in der Vergangenheit gefahrenen Fahrtroute übereinstimmt bzw. übereinstimmen. Die Navigationssteuereinheit 20 weist hierbei einen Speicheralgorithmus auf, der eine von dem Kraftfahrzeug zurückgelegte Strecke selbsttätig in dem Speicherelement 22 speichert. Zudem werden hierbei durch die Positionsparameter Änderungen für eine individuelle Straßenkarte aufgenommen und abgespeichert, wie beispielsweise längere Standzeiten und/oder eine wesentlich kleinere gefahrene Geschwindigkeit als eine zulässige Höchstgeschwindigkeit aufgrund einer Baustelle usw. Eine Speicherung des Streckenverlaufs in dem Speicherelement 22 erfolgt hierbei selbsttätig von der Navigationssteuereinheit 20. Des Weiteren werden über einen längeren Zeitraum von dem Kraftfahrzeug unbenutzte, jedoch bereits gespeicherte Fahrtrouten durch den Speicheralgorithmus aus dem Speicherelement 22 gelöscht. Die Navigationseinheit 20 weist ferner einen Algorithmus auf, der dazu vorgesehen ist, die voraussichtliche Fahrtroute anhand der Positionsparameter und des zumindest einen Streckenparameters zu berechnen. In eine Berechnung 44 der voraussichtlichen Fahrroute geht zudem eine Richtungshistorie ein, die aus einer zeitlichen Abfolge von von der Fahrtrichtung gebildeten Positionsparametern gebildet ist. Unter einer Annahme, dass ein zu Beginn eines Fahrbetriebs gleicher oder zumindest teilweise gleicher Streckenverlauf der aktuellen Fahrtroute und einer früheren zurückgelegten Fahrtroute zu einem gleichen Fahrtroutenziel führt, wird die gespeicherte Fahrtroute als aktuell zu fahrende Fahrtroute von dem Algorithmus bestimmt. Die Abgleichung der Positionsparameter mit den gespeicherten Streckenparametern durch den Algorithmus erfolgt während der gesamten Fahrtroute, so dass eine Abweichung der Positionsparameter von den gespeicherten Streckenparametern sofort erkannt werden kann und gegebenenfalls in der Berechnung 44 der voraussichtlichen Fahrtroute berücksichtigt werden kann, indem weitere, bereits gespeicherte Streckenparameter ermittelt werden und in die Berechnung 44 der voraussichtlichen Fahrtroute eingehen.On the basis of the position parameters, a determination of an anticipated travel route takes place. In this case, a query 42 initially takes place as to whether a path taken by the motor vehicle or whether the position parameter matches or agrees with a stored route parameter of a travel route traveled in the past. The navigation control unit 20 in this case has a memory algorithm which automatically stores a distance covered by the motor vehicle in the memory element 22. In addition, the position parameters hereby record and store changes for an individual road map, such as longer service lives and / or a much lower driven speed than a permissible maximum speed on the basis of a construction site etc. The course of the route in the storage element 22 is automatically stored by the navigation control unit 20. Furthermore, unused but already stored travel routes are deleted from the memory element 22 by the memory algorithm over a relatively long period of time. The navigation unit 20 further has an algorithm which is provided to calculate the prospective route on the basis of the position parameters and the at least one route parameter. A directional history, which is formed from a chronological sequence of positional parameters formed by the direction of travel, is also included in a calculation of the probable driving route. Assuming that an identical or at least partially identical route at the beginning of a driving operation of the current route and a previously traveled route leads to a same route destination, the stored route is determined by the algorithm as the current route to be traveled. The adjustment of the position parameters with the stored route parameters by the algorithm takes place during the entire route, so that a deviation of the position parameters from the stored route parameters can be detected immediately and optionally in the calculation 44 of the estimated route can be taken into account by further, already stored route parameters be determined and enter into the calculation 44 of the probable route.

Für den noch zu befahrenden Teilbereich der voraussichtlichen Fahrtroute führt die Navigationssteuereinheit 20 mittels der Informationen über die zulässige Höchstgeschwindigkeit und die Steigung eine Ermittlung 46 eines Steigungsprofils und eines Geschwindigkeitsprofils für einen zeitlich und/oder räumlich begrenzten Prädiktionshorizont durch. Der zeitlich und/oder räumlich begrenzte Prädiktionshorizont ist hierbei zeitlich und/oder räumlich auf einen Teilbereich der noch zu fahrenden Fahrtroute eingeschränkt, wobei der zeitlich und/oder räumlich begrenzte Prädiktionshorizont kontinuierlich von der Navigationssteuereinheit 20 an einen Streckenverlauf bzw. an eine aktuelle Position anhand der Positionsparameter entlang der Fahrtroute angepasst wird. Eine Ermittlung 46 des Steigungsprofils und des Geschwindigkeitsprofils bzw. die Anpassung des zeitlich und/oder räumlich begrenzten Prädiktionshorizonts erfolgt durch die Navigationssteuereinheit 20 bis zu einem Beenden der Fahrt.For the part of the probable route to be traveled, the navigation control unit 20 uses the information about the maximum permissible speed and the gradient to carry out a determination 46 of a gradient profile and of a speed profile for a temporally and / or spatially limited prediction horizon. The temporally and / or spatially limited prediction horizon is in this case temporally and / or spatially restricted to a subarea of the still to be traveled route, wherein the temporally and / or spatially limited prediction horizon is continuously adjusted by the navigation control unit 20 to a route or to a current position based on the position parameters along the route. A determination 46 of the slope profile and the velocity profile or the adaptation of the temporally and / or spatially limited prediction horizon is carried out by the navigation control unit 20 until the journey is terminated.

Weichen die Positionsparameter und die gespeicherten Streckenparametern voneinander ab, wird von dem Algorithmus der Navigationssteuereinheit 20 eine voraussichtliche Fahrtroute anhand der Positionsparameter und zumindest eines Wahrscheinlichkeitsparameters berechnet. In eine Berechnung 48 gehen neben einer aktuellen Position und einer Fahrtrichtung des Kraftfahrzeugs eine wahrscheinlichste Richtungswahl an jeweils einem nächstliegenden Kreuzungspunkt und eine wahrscheinlichste Richtungswahl an sich daraus ergebenden Folgekreuzungspunkten ein. Der Wahrscheinlichkeitsparameter ist hierbei von der wahrscheinlichsten Richtungswahl gebildet.If the position parameters and the stored route parameters deviate from one another, the algorithm of the navigation control unit 20 calculates an anticipated travel route on the basis of the position parameters and at least one probability parameter. In a calculation 48, in addition to a current position and a direction of travel of the motor vehicle, a most probable direction selection is entered at a respective nearest intersection point and a most probable direction selection at resulting intersection points. The probability parameter is formed from the most probable direction choice.

Die Berechnung 48 der Fahrtroute erfolgt zunächst für einen zeitlich und/oder örtlich begrenzten Prädiktionshorizont, für den auch eine Ermittlung 46 eines Steigungsprofils und eines Geschwindigkeitsprofils, wie bereits oben näher beschrieben, erfolgt. Auch bei einer Eingabe 36 eines Zielorts in die Navigationssteuereinheit 20 durch den Bediener erfolgt eine Ermittlung 46 eines Steigungsprofils und eines Geschwindigkeitsprofils für die Fahrtroute durch die Navigationssteuereinheit 20.The calculation 48 of the travel route initially takes place for a temporally and / or locally limited prediction horizon for which a determination 46 of a gradient profile and a speed profile, as already described in detail above, also takes place. Even with an input 36 of a destination into the navigation control unit 20 by the operator, a determination 46 of a gradient profile and a speed profile for the route is carried out by the navigation control unit 20.

Die Daten der Navigationssteuereinheit 20 werden über das Bussystem an die Betriebssteuereinheit 16 geleitet. Die Betriebssteuereinheit 16 ermittelt hieraus in einem ersten Arbeitsschritt 50 einen Fahrsituationsparameter für die voraussichtliche Fahrtroute. Hierbei wird von der Betriebssteuereinheit 16 zunächst aus dem Steigungsprofil und dem Geschwindigkeitsprofil des zeitlich und/oder räumlich begrenzten Prädiktionshorizonts und einer Längsdynamik des Kraftfahrzeugs ein Leistungsprofil für den zeitlich und/oder räumlich begrenzten Prädiktionshorizont errechnet. Das Steigungsprofil, das Geschwindigkeitsprofil und das Leistungsprofil sind dabei jeweils von einem Routenprofil gebildet .The data of the navigation control unit 20 are sent to the operation control unit 16 via the bus system. The Operating control unit 16 determines therefrom in a first operating step 50 a driving situation parameter for the prospective route. In this case, a performance profile for the temporally and / or spatially limited prediction horizon is first calculated by the operation control unit 16 from the slope profile and the velocity profile of the temporally and / or spatially limited prediction horizon and a longitudinal dynamics of the motor vehicle. The slope profile, the speed profile and the performance profile are each formed by a route profile.

Zudem werden von der Betriebssteuereinheit 16 weitere Parameter, die von einem Fahrzeugzustandsparameter und/oder einem Umgebungsparameter gebildet sind, bei der Ermittlung in dem ersten Arbeitsschritt 50 des Fahrsituationsparameters verwendet. Der Fahrzeugzustandsparameter kann hierbei von einer aktuellen Geschwindigkeit, einer Richtung und/oder weiteren, dem Fachmann als sinnvoll erscheinenden Parametern gebildet sein. Der Umgebungsparameter wird von Parametern einer Umgebung des Kraftfahrzeugs gebildet, wie beispielsweise eine aktuelle Außentemperatur, eine aktuelle Steigung usw. Hierzu weist das Fahrzeugsystem 10 eine Sensoreinheit 32 zu einer Erfassung der Umgebungsparameter auf. Grundsätzlich ist es aber auch denkbar, dass die Sensoreinheit 32 eine von dem Fahrzeugsystem 10 getrennte Einheit bildet. Die Sensoreinheit 32 kann hierbei einen Temperatursensor, einen Regensensor und/oder weitere, dem Fachmann als sinnvoll erscheinende Sensoren aufweisen.In addition, the operating control unit 16 uses further parameters, which are formed by a vehicle state parameter and / or an environmental parameter, in the determination in the first operating step 50 of the driving situation parameter. In this case, the vehicle state parameter can be formed by a current speed, a direction and / or further parameters that appear appropriate to the person skilled in the art. The environmental parameter is formed by parameters of an environment of the motor vehicle, such as a current outside temperature, a current gradient, etc. For this purpose, the vehicle system 10 has a sensor unit 32 for detecting the environmental parameters. In principle, however, it is also conceivable that the sensor unit 32 forms a separate unit from the vehicle system 10. In this case, the sensor unit 32 can have a temperature sensor, a rain sensor and / or further sensors that appear appropriate to the person skilled in the art.

Die Routenprofile werden von der Betriebssteuereinheit 16 zudem online mit den aktuellen Fahrzeugzustandsparametern und/oder den aktuellen Umgebungsparametern überprüft und/oder abgeglichen. Anschließend werden die Routenprofile zusammen mit den aktuellen Fahrzeugzustandsparametern und/oder den aktuellen Umgebungsparametern von der Betriebssteuereinheit 16 innerhalb des zeitlich und/oder räumlich begrenzten Prädiktionshorizonts analysiert. Dabei werden die Routenprofile und die aktuellen Fahrzeugzustandsparameter und/oder die aktuellen Umgebungsparameter nach Merkmalen für einen Fahrsituationsparameter durchsucht. Anhand des Fahrsituationsparameters wird die voraussichtliche Fahrtroute bzw. ein Teilbereich der voraussichtlichen Fahrtroute, insbesondere innerhalb des zeitlich und/oder räumlich begrenzten Prädiktionshorizonts, unter vorausschauender Betrachtung klassifiziert. Zunächst erfolgt eine Klassifikation 52 nach generellen Fahrsituationen, wie beispielsweise eine Stadtfahrt, eine Überlandfahrt , eine Autobahnfahrt usw. Zudem erfolgt mittels der Routenprofile und den aktuellen Fahrzeugzustandsparametern und/oder den aktuellen Umgebungsparametern zusammen mit der Navigationssteuereinheit 20 eine zusätzliche Spezifikation der ermittelten Fahrsituationsparameter für die voraussichtliche Fahrtroute. Die ermittelten Fahrsituationsparameter werden hierbei von der Betriebssteuereinheit 20 nach Eigenschaften unterteilt, wie beispielsweise schnell, langsam, bergig, flach, kurvig, nass, trocken usw.The route profiles are also checked and / or compared online by the operation control unit 16 with the current vehicle state parameters and / or the current environment parameters. Then the route profiles are put together analyzed with the current vehicle state parameters and / or the current environmental parameters of the operation control unit 16 within the temporally and / or spatially limited prediction horizon. The route profiles and the current vehicle state parameters and / or the current environmental parameters are searched for features for a driving situation parameter. Based on the driving situation parameter, the prospective route or a subarea of the probable route, in particular within the temporally and / or spatially limited prediction horizon, is classified under foresighted consideration. First, there is a classification 52 for general driving situations, such as city driving, overland travel, highway driving, etc. In addition, by means of the route profiles and the current vehicle state parameters and / or the current environment parameters together with the navigation control unit 20, an additional specification of the determined driving situation parameters for the probable route. The ascertained driving situation parameters are hereby subdivided by the operating control unit 20 according to characteristics such as, for example, fast, slow, hilly, flat, curvy, wet, dry, etc.

Mittels der von der Betriebssteuereinheit 16 ermittelten Fahrsituationsparameter wird daraufhin in einem nächsten Arbeitsschritt 54 ein von Parametern gebildeter Parametersatz zu einer optimierten Einstellung der Antriebseinheit 14 festgelegt, wobei der Parametersatz bzw. mehrere, auf die unterschiedlichen Fahrsituationen angepasste Parametersätze bereits in dem Speicherelement 22 hinterlegt ist bzw. sind. Durch die Parameter bzw. den Parametersatz wird ein Energiemanagement bzw. eine effiziente Anpassung der Antriebseinheit 14 an die voraussichtlichen Fahrtroute in dem zeitlich und/oder räumlich begrenzten Prädiktionshorizont bzw. unter vorausschauender Betrachtung der Fahrtroute eingestellt .By means of the driving situation parameters ascertained by the operating control unit 16, a parameter set formed by parameters is then set to an optimized setting of the drive unit 14 in a next step 54, wherein the parameter set or a plurality of parameter sets adapted to the different driving situations is already stored in the memory element 22 or . are. The parameters or the parameter set is used for energy management or an efficient adaptation of the Drive unit 14 to the prospective route in the temporally and / or spatially limited prediction horizon or under predictive consideration of the route set.

Die Parametersätze für generelle Klassifikation sind zudem vorab vor einer Hinterlegung in dem Speicherelement 22 optimiert auf die generelle Fahrsituation bzw. den generellen Fahrsituationsparameter abgestimmt, so dass ein schneller und direkter Zugriff jederzeit möglich ist. Die Parameter eines der Parametersätze sind hierbei von einer Leistungsgrenze für die unterschiedlichen Antriebsarten, einem von einem idealen Ladezustand gebildeten Sollladezustand für ein Energiespeichermittel, wie beispielsweise eine Kraftfahrzeugtraktionsbatterie und/oder eine Bordnetzbatterie, ein zulässiger Betriebsbereich für ein Laden des Energiespeichermittels, eine Einstellung für ein Getriebeschaltprogramm, eine Getriebesollübersetzung, ein Ansteuerwert für weitere, antriebsunabhängige Komponenten, wie beispielsweise für eine Klimaanlage, eine Pumpe, einen Ventilator usw., gebildet. The parameter sets for general classification are also optimized in advance of a deposit in the memory element 22 optimized for the general driving situation or the general driving situation parameters, so that a fast and direct access is possible at any time. The parameters of one of the parameter sets are in this case of a power limit for the different types of drive, a desired state of charge for an energy storage medium formed by an ideal state of charge, such as a motor vehicle traction battery and / or an on-board battery, an allowable operating range for charging the energy storage device, a setting for a transmission shift program , a transmission target gear ratio, a drive value for further, drive-independent components, such as for an air conditioner, a pump, a fan, etc., formed.
