Abstract

The method involves storing vehicle control parameters (FSP) in a control unit (1), and retrieving the control parameters for controlling an operation of a vehicle (2). The control parameters are determined based on an analysis concerning utilization of the vehicle. Load collectives (LK) arising during operation of the vehicle and acting on the vehicle are detected and stored during a period of time. The control parameters are adjusted during operation of the vehicle based on the load collectives. The load collectives are speed distribution, arising drive- and/or acceleration torque, arising, load, rotational speed of a drive machine, pitches, gear changes and/or braking operations with associated vehicle velocity and associated braking pressure.

1 schematisch eine Darstellung eines Verfahrens zum Steuern des Betriebs eines Fahrzeugs mit einem Elektro- oder Hybridantrieb. 1 schematically a representation of a method for controlling the operation of a vehicle with an electric or hybrid drive.

Dabei zeigt die einzige Figur eine schematische Darstellung eines Verfahrens zum Steuern des Betriebs eines Fahrzeugs 2 mit einem Elektro- oder Hybridantrieb. Dabei ist im Fahrzeug 2 eine Steuereinheit 1 zur Steuerung und/oder Regelung eines nicht dargestellten Antriebsstrangs des Fahrzeugs 2 integriert.The single figure shows a schematic representation of a method for controlling the operation of a vehicle 2 with an electric or hybrid drive. It is in the vehicle 2 a control unit 1 for controlling and / or regulating a non-illustrated drive train of the vehicle 2 integrated.

Die Steuereinheit 1 im Antriebsstrang des Fahrzeugs 2 ist bevorzugt als herkömmliche kombinierte Motor-, Getriebe- und Kupplungsteuereinheit ausgeformt, wobei die Steuereinheit 1 als integrierte Steuereinheit ausgebildet ist, bei welcher die einzelnen Funktionen zur Steuerung und/oder Regelung von Antriebsmaschine, Kupplung, Energiespeicher und/oder Getriebe als Programmabläufe auf einem Mikroprozessor ablaufen. Weiterhin sind in der Steuereinheit 1 Mittel zur Erfassung von herkömmlichen Betriebsparametern BP und/oder Betriebsgrößen BG des Fahrzeugs, der Antriebsmaschinen, der Kupplung, der Energiespeicher und/oder des Getriebes vorhanden.The control unit 1 in the drive train of the vehicle 2 is preferably formed as a conventional combined engine, transmission and clutch control unit, wherein the control unit 1 is designed as an integrated control unit, in which run the individual functions for controlling and / or control of prime mover, clutch, energy storage and / or transmission as program flows on a microprocessor. Furthermore, in the control unit 1 Means for detecting conventional operating parameters BP and / or operating variables BG of the vehicle, the engine, the clutch, the energy storage and / or the transmission available.

In der Steuereinheit 1 sind herkömmliche Fahrzeugsteuerparameter FSP hinterlegt, welche zum Steuern des Betriebs des Fahrzeugs 2 abrufbar sind. Diese hinterlegten Fahrzeugsteuerparameter FSP werden während der Entwicklung des Fahrzeugs 2 anhand von Prognosen bezüglich der zukünftigen Nutzung des Fahrzeugs 2 ermittelt und in der Steuereinheit 1 hinterlegt. Beispielweise ist in der Steuereinheit 1 ein stochastisches Fahrzeugmodell gespeichert, dessen Modellwerte im stationären Zustand des Fahrzeuges 2, z. B. auf einem Prüfstand, ermittelt werden. Dabei werden die Modellwerte unter solchen Bedingungen bestimmt, bei denen das Fahrzeug 2 mit exakt definierten und gleich bleibenden Werten betrieben wird. Der Modellwert einer der Betriebsgrößen des Fahrzeugs 2, z. B. der Fahrzeuggeschwindigkeit, wird dann als Summe der Fahrwiderstände, die einer Antriebskraft betragsmäßig gleich sind, direkt über ein angefordertes Motordrehmoment ermittelt. Diese Modellwerte sind als Ausgangswerte aller Regelungen und/oder Steuerungen des Fahrzeuges 2 in der Steuereinheit 1 hinterlegt und können zur Steuerung und/oder Regelung des Betriebs des Fahrzeugs 2 verwendet werden. Herkömmlicherweise werden diese Fahrzeugsteuerparameter FSP, mit denen eine Fahrstrategie des Fahrzeugs 2 umsetzbar ist, während des Betriebs des Fahrzeugs 2 nicht mehr verändert.In the control unit 1 are stored conventional vehicle control parameters FSP, which are used to control the operation of the vehicle 2 are available. These stored vehicle control parameters FSP are used during the development of the vehicle 2 based on forecasts regarding the future use of the vehicle 2 determined and in the control unit 1 deposited. For example, in the control unit 1 stored a stochastic vehicle model whose model values in the stationary state of the vehicle 2 , z. B. on a test bench, are determined. The model values are determined under conditions in which the vehicle 2 operated with exactly defined and consistent values. The model value of one of the operating variables of the vehicle 2 , z. As the vehicle speed, is then the sum of the driving resistances, which are equal in magnitude to a driving force, directly on a requested engine torque determined. These model values are the starting values of all controls and / or controls of the vehicle 2 in the control unit 1 deposited and can be used to control and / or regulating the operation of the vehicle 2 be used. Conventionally, these vehicle control parameters FSP, with which a driving strategy of the vehicle 2 is feasible during operation of the vehicle 2 not changed anymore.

Bei der Durchführung des erfindungsgemäßen Verfahrens werden während des Betriebs des Fahrzeugs 2 auftretende und auf das Fahrzeug 2 einwirkende Lastkollektive LK während eines vorgebbaren Zeitraums, beispielsweise einer einzelnen Fahrt, erfasst und/oder ermittelt und aufgezeichnet. Dabei werden die ermittelten Lastkollektive LK in einer Speichereinheit 3 in der Steuereinheit 1 abgelegt.In carrying out the method according to the invention are during operation of the vehicle 2 occurring and on the vehicle 2 acting load collective LK during a predetermined period of time, for example, a single ride, recorded and / or determined and recorded. In this case, the determined load collectives LK are stored in a memory unit 3 in the control unit 1 stored.

Zur Erfassung und/oder Ermittlung der Lastkollektive LK werden der Steuereinheit 1 von mindestens einer Erfassungseinheit und/oder einem anderen Fahrassistenzsystem und/oder einer anderen Steuereinheit in nicht näher dargestellter Art und Weise drahtgebunden und/oder drahtlos aktuell erfasste/ermittelte Werte einer oder mehrerer Betriebsgrößen BG und/oder Betriebsparameter BP zugeführt. Aus diesen zugeführten Betriebsgrößen BG und/oder Betriebsparametern BP werden in der Steuereinheit 1 Lastkollektive LK direkt erfasst oder ermittelt.For detecting and / or determining the load collective LK the control unit 1 supplied by at least one detection unit and / or another driver assistance system and / or another control unit in a manner not shown wired and / or wireless currently detected / determined values of one or more operating variables BG and / or operating parameters BP. From these supplied operating variables BG and / or operating parameters BP are in the control unit 1 Load collective LK recorded or determined directly.

Als Betriebsgrößen BG und/oder Betriebsparameter BP werden beispielsweise eine aktuelle Fahrzeuggeschwindigkeit und/oder eine eingelegte Fahrstufe, eine aktuelle Steigung, eine aktuelle Fahrtrichtung, eine aktuelle Windstärke und/oder ein aktuelles Motordrehmoment erfasst.As operating variables BG and / or operating parameters BP, for example, a current vehicle speed and / or an engaged driving position, a current gradient, a current driving direction, a current wind force and / or a current engine torque are detected.

Als Lastkollektive LK werden beispielsweise eine Geschwindigkeitsverteilung, auftretende Antriebs- und/oder Beschleunigungsmomente, auftretende Steigungen, eine Beladung, eine Drehzahl der Antriebsmaschine, auftretende Gangwechsel und/oder Bremsvorgänge mit zugehöriger Fahrzeuggeschwindigkeit und zugehörigem Bremsdruck erfasst und/oder ermittelt.As load collective LK, for example, a speed distribution, occurring driving and / or acceleration torques, occurring gradients, a load, a rotational speed of the engine, occurring gear changes and / or braking processes with associated vehicle speed and associated brake pressure are detected and / or determined.
