Abstract

The control of vehicle drive system involving the processing of information for determining the travel environment, the driving condition, position determination etc, provides improved and more efficient travel by using 'look-ahead' variables for taking action on the vehicle systems, such as the engine, automatic transmission and differential, in which the information and data and the 'look-ahead' variables are ascertained by suitable sensors, e.g. GPS, DGPS or TV cameras, and/or the data derived from them by e.g. an observer-based or a model-based method.

Description

Die vorliegende Erfindung betrifft ein Verfahren zur Steuerung von Antriebssystemen eines Kraftfahrzeugs gemäß dem Oberbegriff das Patentanspruchs 1.The present invention relates to a method for Control of drive systems of a motor vehicle according to the preamble of claim 1.

Antriebssysteme und insbesondere automatische Last­ schaltgetriebe werden üblicherweise anhand von aktuell vor­ handenen Informationen über relevante Systemparameter ge­ steuert.Drive systems and especially automatic load manual transmissions are usually based on current available information about relevant system parameters controls.

Die DE 196 00 734 A1 offenbart ein Verfahren zur Steuerung von Aggregaten und/oder Systemen eines Kraftfahr­ zeugs unter Verarbeitung von Informationen zur Erfassung der Fahrumgebung, des Fahrzustands, zur Positionsbestimmung oder dergleichen, welches aktuelle Daten miteinander ver­ knüpft und zu einer Stellgröße aufbereitet, mit der zumin­ dest ein Aggregat des Fahrzeugs in seiner Arbeitsweise be­ einflussbar ist.DE 196 00 734 A1 discloses a method for Control of units and / or systems of a motor vehicle stuff processing information for collection the driving environment, the driving condition, for position determination or the like, which ver current data ver ties and processed into a manipulated variable with which at least least an aggregate of the vehicle in its mode of operation can be influenced.

Diese aktuellen Daten können jedoch zeitlich derart variieren, dass eine ständige und schnelle Anpassung der Stellgröße erforderlich ist. Dies in Verbindung mit einer gewissen Reaktionszeit des betreffenden Systems kann zu Effekten führen, die die Sicherheit, die Wirtschaftlichkeit und die Effizienz sowie den Komfort negativ beinflussen können. Wichtige Beispiele sind u. a. beim Einsatz eines Automatikgetriebes das Kriechen in der Ebene, das Zurück­ rollen am Berg und Pendelschaltungen. Auch kann es hierbei zu Hochschaltungen in Kurven und bergab und zu unerwünsch­ ten Schwingungen im Abtriebsstrang kommen.However, this current data can be timed in this way that vary a constant and quick adjustment of the Manipulated variable is required. This in connection with a certain response time of the system in question may Effects that lead to security, economy and negatively affect efficiency and comfort can. Important examples include a. when using a Automatic transmission, the creep in the plane, the back roll on the mountain and pendulum circuits. It can also do this to upshifts in curves and downhill and to undesirable vibrations in the drive train.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ausgehend von dem genannten Stand der Technik ein Verfahren zur Steuerung von Antriebssystemen eines Kraft­ fahrzeugs zu entwickeln, derart, dass die geschilderten Probleme möglichst vermieden werden.The present invention is therefore based on the object based on the state of the art Method for controlling drive systems of a force vehicle to develop such that the described Problems should be avoided if possible.

Diese Aufgabe ist gemäß der Erfindung durch die Merk­ male des Anspruchs 1 gelöst. Weitere Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor.This object is according to the invention by the Merk male of claim 1 solved. Further refinements of the Invention emerge from the subclaims.

Dementsprechend wird vorgeschlagen, unter Verarbeitung von Informationen zur Erfassung der Fahrumgebung, des Fahr­ zustandes und weiterer relevanter Daten, auf diesen Infor­ mationen basierende vorausschauende Größen zu verwenden, um auf z. B. Motor, Automatikgetriebe und Differential einzu­ greifen.Accordingly, it is suggested under processing of information to record the driving environment, the driving state and other relevant data, on this information to use forward-looking quantities based on on z. B. engine, automatic transmission and differential to grab.

Gemäß der Erfindung werden diese vorausschauenden Grö­ ßen mittels geeigneter Sensoren ermittelt. Derartige Senso­ ren können beispielsweise GPS- und DGPS-Sensoren (GPS = Global Positioning System, DGPS = Differential GPS) sowie Abstandsradargeräte, Funkempfänger, Infrarot-/Licht­ empfänger, TV-Kameras oder ähnliche sein.According to the invention, these predictive sizes determined using suitable sensors. Such Senso For example, GPS and DGPS sensors can be used (GPS = Global Positioning System, DGPS = Differential GPS) as well as distance radars, radio receivers, infrared / light receivers, TV cameras or the like.

Mittels dieser Sensoren oder der aus den Daten dieser Sensoren gebildeten Größen (z. B. mittels beobachter- oder modellbasierter Verfahren) wird der innerhalb einer be­ stimmten Zeit- oder Raumspanne unmittelbar bevorstehende Wert relevanter Daten bzw. Größen ermittelt oder berechnet. Derartige Daten sind erfindungsgemäß beispielsweise Ge­ schwindigkeit des Fahrzeugs, Abstand, Position, Trajekto­ rie, Verkehrsdichte, Kraftschluß der Reifen, Informationen aus aktiven Schildern, Ampeln etc. oder aus diesen Werten abgeleitete Größen, wie z. B. der Beschleunigung des Fahr­ zeugs.By means of these sensors or from the data of these Variables formed by sensors (e.g. by means of observers or model-based procedure) will be within a be agreed time or space span immediately upcoming Value of relevant data or quantities determined or calculated. According to the invention, such data are, for example, Ge vehicle speed, distance, position, trajectory rie, traffic density, adhesion of the tires, information from active signs, traffic lights etc. or from these values  derived sizes, such as B. the acceleration of driving stuff.

In einem nächsten Schritt werden mit geeigneten Algo­ rithmen im Rahmen eines erfindungsgemäßen vorausschauenden Antriebsmanagements antriebsspezifische Maßnahmen eingelei­ tet, wobei z. B. die Steuerung von Getriebe, Motor oder auch von einem aktiven Differential beeinflusst wird.The next step is to use suitable algo rithms in the context of a forward-looking Drive management, drive-specific measures tet, z. B. the control of transmission, engine or is influenced by an active differential.

Mittels des Verfahrens kann Kriechen in der Ebene und Zurückrollen am Berg effektiv verhindert werden, da die Daten der unmittelbar bevorstehenden Fahrumgebung bereits ausgewertet und berücksichtigt werden.By means of the method can creep in the plane and Rolling back on the mountain can be prevented effectively because the Data of the imminent driving environment already be evaluated and taken into account.

Dies resultiert auch in einer vorausschauenden Schalt­ strategie, die dazu führt, dass die Schalthäufigkeit redu­ ziert wird und Pendelschaltungen vermieden werden.This also results in a predictive shift strategy that leads to a reduced number of starts is adorned and pendulum circuits are avoided.

Auch kann z. B. verhindert werden, dass vor einer für den Fahrer noch nicht sichtbaren Kurve oder einer Gefäll­ strecke hochgeschaltet wird.Also, e.g. B. can be prevented in front of a for the driver is not yet able to see a curve or a slope range is shifted up.

Im Rahmen des Verfahrens wird eine vorausschauende Antriebsstrangdämpfung bei starkem Lastwechselbetrieb über eine entsprechende Kupplungsregelung und Kupplungsbefüllung realisiert.As part of the process, a forward-looking Powertrain damping in the case of heavy duty cycle operation a corresponding clutch control and clutch filling realized.

Durch das erfindungsgemäße Verfahren wird außerdem bei einer gleichzeitigen Erhöhung der Fahrsicherheit und des Fahrkomforts der Verbrauch und die CO2-Emmision reduziert, beispielsweise durch die Adaption an regelmäßig wiederkeh­ rende Routen.The method according to the invention also reduces consumption and CO 2 emissions with a simultaneous increase in driving safety and driving comfort, for example by adapting to regularly recurring routes.
