Verfahren zum Betrieb eines Bordcomputers eines Method for operating an on-board computer of a
Kraftfahrzeuges motor vehicle
Die Erfindung betrifft ein Verfahren zum Betrieb eines Bordcomputers eines Kraftfahrzeuges, bei dem Fahrparameter er- fasst und die Fahrparameter verschiedenen Zeit-/Strecken- parametern zugeordnet und dargestellt werden, und mit einer Auswahl für verschiedene Betriebsprofile. The invention relates to a method for operating an on-board computer of a motor vehicle, in which driving parameters are detected and the driving parameters are assigned and displayed to different time / distance parameters, and with a selection for different operating profiles.
Solche Verfahren werden in Bordcomputern von heutigen Kraftfahrzeugen häufig eingesetzt, um die Fahrparameter, wie einen Kraftstoffverbrauch bezogen auf eine Strecke, eine Durch- Schnittsgeschwindigkeit, eine Fahrzeit oder Fahrstrecke darzustellen. Die Fahrparameter werden zudem häufig mit Zeit-/ Streckenparametern, wie einem Kurzzeitspeicher, einem Langzeitspeicher, einem Lebensspeicher oder einem individuell vom Fahrer einzustellenden Speicher ausgewertet und dargestellt. Der Fahrer des Kraftfahrzeuges kann zudem ein eigenes Fahrerprofil für sich selbst zusammenstellen oder ein Betriebsprofil, wie beispielsweise einen Eco-, Sport- oder Komfort-Modus auswählen . Das eingangs genannte Verfahren ist aus der Praxis bekannt.Such methods are often used in on-board computers of today's motor vehicles to represent the driving parameters such as a fuel consumption in relation to a distance, an average speed, a travel time or driving distance. The driving parameters are also often evaluated and displayed with time / distance parameters, such as a short-term memory, a long-term memory, a life memory or a memory to be set individually by the driver. The driver of the motor vehicle can also put together his own driver profile for himself or select an operating profile, such as an eco, sports or comfort mode. The aforementioned method is known from practice.
Nachteilig bei dem bekannten Verfahren ist, dass der Bordcomputer nur eine Gesamtbetrachtung der Fahrparameter über Zeit- und Streckenparameter ermöglicht. Eine individuell auf das aktuelle Betriebsprofil angepasste Darstellung der Fahrpara- meter ist nicht möglich. A disadvantage of the known method is that the on-board computer only allows an overall view of the driving parameters over time and distance parameters. A representation of the driving parameters individually adapted to the current operating profile is not possible.
Der Erfindung liegt das Problem zugrunde, ein Verfahren der eingangs genannten Art so zu gestalten, dass es dem Fahrer des Kraftfahrzeuges Informationen über die Fahrparameter in Abhängigkeit des aktuellen Betriebsprofils zur Verfügung stellt . Dieses Problem wird erfindungsgemäß dadurch gelöst, dass der Bordcomputer die auf Zeit-/Streckenparameter ermittelten Fahrparameter in Abhängigkeit von den Betriebsprofilen berechnet und darstellt. The invention is based on the problem of designing a method of the type mentioned above so that it provides the driver of the motor vehicle with information about the driving parameters as a function of the current operating profile. This problem is inventively achieved in that the on-board computer calculates and represents the driving parameters determined on time / route parameters in dependence on the operating profiles.
Durch diese Gestaltung ermöglicht das erfindungsgemäße Verfahren eine Erfassung von Fahrparametern wie Verbrauch und der Fahrtzeit unter Berücksichtigung der jeweiligen Betriebsprofile. Damit kann beispielsweise ausgewertet werden, wie lange und wie häufig ein Fahrer den Sportmodus gewählt hat. Zudem lassen sich Kraftstoffverbräuche in Abhängigkeit der einzelnen Fahrer oder der gewählten Betriebsprofile auswerten und darstellen. Dank der Erfindung erhält der Fahrer des Kraftfahrzeuges die Informationen über die Fahrparameter in Abhängigkeit von dem jeweiligen Betriebsprofil des Kraftfahrzeuges . By virtue of this configuration, the method according to the invention makes it possible to detect driving parameters, such as consumption and the travel time, taking into account the respective operating profiles. This can be used, for example, to evaluate how long and how often a driver has chosen the sport mode. In addition, fuel consumption can be evaluated and displayed depending on the individual driver or the selected operating profiles. Thanks to the invention, the driver of the motor vehicle receives the information about the driving parameters as a function of the respective operating profile of the motor vehicle.
Die Handhabung des nach dem erfindungsgemäßen Verfahren betriebenen Bordcomputers gestaltet sich besonders einfach, wenn bei jedem Wechsel der Betriebsprofile die Fahrparameter für das gewählte Betriebsprofil dargestellt werden. Durch diese Gestaltung erhält der Fahrer des Kraftfahrzeuges durch eine einfache Wahl des Betriebsprofils automatisch die Informationen der dieses Betriebsprofil betreffenden Fahrparame- ter . Schaltet der Fahrer beispielsweise von einem ökonomischen Betriebsprofil auf ein sportliches Betriebsprofil um, erhält der Fahrer bei der Auswahl des Kraftstoffverbrauchs den für den sportlichen Fahrmodus abgespeicherten Wert des Kraftstoffverbrauchs. Die Darstellung der Fahrparameter der den Fahrer betreffenden Betriebsprofile kann einfach über den Start des Kraftfahrzeuges mit einem individuellen Schlüssel oder Zugangscode des Fahrers aktiviert werden. The handling of the on-board computer operated according to the method according to the invention is particularly simple if, each time the operating profiles are changed, the driving parameters for the selected operating profile are displayed. As a result of this design, the driver of the motor vehicle automatically obtains the information of the driving parameters relating to this operating profile through a simple choice of the operating profile. For example, if the driver switches from an economic operating profile to a sporty operating profile, the driver receives the fuel consumption value stored for the sporty driving mode when selecting the fuel consumption. The representation of the driving parameters of the operating profiles relating to the driver can be easily activated via the start of the motor vehicle with an individual key or access code of the driver.
Die Betriebsprofile lassen sich gemäß einer anderen vorteil- haften Weiterbildung der Erfindung einfach mit anderen abgespeicherten Betriebsprofilen vergleichen, wenn die Fahrparameter der einzelnen Betriebsprofile miteinander verglichen werden. Die Fahrparameter sind hierdurch über verschiedene Betriebsprofile miteinander verknüpft und können weiter verarbeitet oder auf den Wunsch des Fahrers hin dargestellt werden. Durch diese Gestaltung können beispielsweise Ranglisten von Fahrern mit dem geringsten Kraftstoffverbrauch erstellt werden . According to another advantageous development of the invention, the operating profiles can be easily compared with other stored operating profiles if the driving parameters of the individual operating profiles are compared with one another become. The driving parameters are thereby linked together via different operating profiles and can be further processed or displayed at the request of the driver. By this design, for example, leaderboards of drivers with the lowest fuel consumption can be created.
Zur weiteren Vereinfachung des Vergleichs der Betriebsprofile trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn aus den Fahrparametern der einzelnen Betriebsprofile Gesamtwerte oder Durchschnittswerte berechnet werden. Damit kann der Fahrer durch die Auswahl der berechneten Durchschnittswerte erkennen, ob der eigene Kraftstoffverbrauch relativ hoch oder niedrig ist. Auch besteht für den Fahrer des Kraftfahrzeuges die Möglichkeit zu erkennen, wie groß der Einfluss der Wahl des sportlichen Fahrmodus, beispielsweise auf den Durchschnittsverbrauch des Kraftstoffs ist . Die Fahrparameter lassen sich neben festgelegten Zeit-/ Streckenparametern gemäß einer anderen vorteilhaften Weiterbildung der Erfindung auch individuell erfassen, wenn der Bordcomputer eine Festlegung von Beginn und Ende von Zeit-/ Streckenparameter durch den Fahrer erfasst. To further simplify the comparison of the operating profiles, it contributes according to another advantageous embodiment of the invention, when total values or average values are calculated from the driving parameters of the individual operating profiles. This allows the driver to see, by selecting the calculated average values, whether their own fuel consumption is relatively high or low. It is also possible for the driver of the motor vehicle to recognize how great the influence of the choice of the sporty driving mode is, for example on the average consumption of the fuel. The driving parameters can also be detected individually in addition to specified time / distance parameters according to another advantageous embodiment of the invention, when the on-board computer detects a determination of the beginning and end of time / distance parameters by the driver.
Die Darstellung der Fahrparameter für das abgespeicherte Fahrerprofil oder in direkter Abhängigkeit von dem gewählten Fahrmodus gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders einfach, wenn die Dar- Stellung der Fahrparameter in Abhängigkeit von den Betriebsprofilen variiert. Hierdurch ist es beispielsweise möglich, den Fahrparameter Fahrzeit in einem Komfort-Modus in Minuten und in einem Sportmodus in 1/100 Sekunden darzustellen. Die Erfindung lässt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips ist eine davon in der Zeichnung dargestellt und wird nachfolgend beschrieben. Diese zeigt in The representation of the driving parameters for the stored driver profile or in direct dependence on the selected driving mode is particularly simple according to another advantageous development of the invention, when the representation of the driving parameters varies depending on the operating profiles. This makes it possible, for example, to represent the driving parameter driving time in a comfort mode in minutes and in a sports mode in 1/100 seconds. The invention allows numerous embodiments. To further clarify its basic principle, one of them is in the drawing and will be described below. This shows in

The on-board computer 1 is connected to a wheel sensor 4 and to a motor sensor 5 of the internal combustion engine 2. Furthermore, the on-board computer 1 has a connection with a clock 6 and with a control panel 7 for inputting information by the driver. The operator can enter information into the on-board computer 1 or identify himself via the control unit 7 so that the on-board computer 1 activates a driver profile which is preferred by the driver.
Figur 2 zeigt das Verfahren zum Betrieb des Bordcomputers 1. Der Bordcomputer 1 erfasst über den Radsensor 4 Fahrparameter 8, wie Daten zur Geschwindigkeit (v) und der gefahrenen Stre- cke (s) . Weitere Fahrparameter 8 wie den Kraftstoffverbrauch (B) erhält der Bordcomputer 1 von dem Motorsensor 5 der Brennkraftmaschine 2. Über die Uhr 6 ermittelt der Bordcomputer 1 die Fahrzeit (t) . Die Fahrparameter 8 werden Zeit-/Streckenparametern 9 zugeordnet, so dass die Fahrparameter 8 mit einem Kurzzeitspeicher Tl, einem Langzeitspeicher T2, einem LebensdauerSpeicher T3 und einer Wegstrecke Sl verrechnet werden können. Hierdurch lässt sich beispielsweise der Kraftstoffverbrauch B wahlweise über die Wegstrecke Sl oder einen vorgesehenenFIG. 2 shows the method for operating the on-board computer 1. The on-board computer 1 acquires driving parameters 8 via the wheel sensor 4, such as data on the speed (v) and the distance traveled (s). Further driving parameters 8 such as the fuel consumption (B) receives the on-board computer 1 from the engine sensor 5 of the internal combustion engine 2. About the clock 6, the on-board computer 1 determines the travel time (t). The driving parameters 8 are assigned to the time / distance parameters 9, so that the driving parameters 8 can be offset with a short-term memory T1, a long-term memory T2, a lifetime memory T3 and a distance S1. This allows, for example, the fuel consumption B either over the distance Sl or one provided

Mittels des Bedienteils 7 kann der Fahrer des Kraftfahrzeuges ein Betriebsprofil 10 auswählen, was von dem Bordcomputer 1 ebenfalls erfasst wird. Als Betriebsprofil 10 ist beispielsweise ein Eco-Modus (E-M) , ein Sport-Modus (S-M) oder ein Komfort-Modus (C-M) auswählbar. Calculate period, for example, the temporary memory Tl. By means of the operating part 7, the driver of the motor vehicle can select an operating profile 10, which is also detected by the on-board computer 1. For example, an Eco Mode (EM), a Sport Mode (SM) or a Comfort Mode (CM) can be selected as the operating profile 10.
Der Bordcomputer 1 bildet aus den Fahrparametern 8, dem Zeit-/Streckenparameter 9 und dem Betriebsprofil 10 eine dreidimensionale Matrix und ermöglicht damit beispielsweise eine Darstellung des Kraftstoff erbrauchs (B) in Abhängigkeit von dem gewählten Betriebsprofil 10 oder den Zeit-/Strecken- parametern 9 oder einer vom Fahrer ausgewählten Verknüpfung von Betriebsprofil 10 und Zeit-/Streckenparametern 9. The on-board computer 1 forms a three-dimensional matrix from the driving parameters 8, the time / distance parameter 9 and the operating profile 10 and thus makes it possible, for example, to display the fuel consumption (B) as a function of the selected operating profile 10 or the time / distance parameters 9 or a driver-selected combination of operating profile 10 and time / distance parameters 9.
