Description
Die Erfindung betrifft ein Fahrdynamikregelsystem für Fahrzeuge, mit mindestens einer Signalverteilung, der Fahrzeugdaten, Umweltdaten und Daten bzgl. des Fahrerwunsches als Eingangsdaten zugeführt werden und mehreren steuer- bzw. regelbaren Subsystemen, die die Dynamik des Fahrzeugs modifizieren, wie eine fahrerunabhängig verstellbare Lenkung, ein fahrerunabhängig verstellbares Fahrwerk, eine fahrerunabhängig verstellbare Bremse und einen fahrerunabhängig verstellbaren Antriebsstrang.The The invention relates to a vehicle dynamics control system for vehicles, with at least a signal distribution, the vehicle data, environmental data and data regarding the driver's request are supplied as input data and several control or controllable subsystems that modify the dynamics of the vehicle, like a driver independent adjustable steering, a driver independent adjustable chassis, a driver independent adjustable brake and a driver independent adjustable drivetrain.
Sowohl der Komfort als auch die Sicherheitstechnik nehmen in Fahrzeugen immer mehr zu. Dies führt dazu, dass Fahrzeuge mit immer mehr elektronischen und elektromechanischen Komponenten bzw. Subsystemen ausrüstet werden. Jedes Subsystem bedingt sein eigenes Steuergerät um Sensorsignale zu plausibilisieren, aufzubereiten, Stellsignale zu berechnen und seine Aktuatoren einzuregeln. Jedes dieser Subsysteme bzw. Steuergeräte arbeitet aber für sich (Stand-alone) und weiß oft nichts von den anderen.Either the comfort as well as the safety technology take in vehicles more and more. this leads to to that vehicles with more and more electronic and electromechanical Components or subsystems are equipped. Every subsystem requires its own controller to plausibility check sensor signals, prepare, control signals to calculate and adjust its actuators. Each of these subsystems or control devices but works for himself (stand alone) and knows often nothing from the others.
Neben
Komfortsystemen, wie automatische Scheibenheber, Außenspiegelverstellung
etc. nimmt vor allem auch die Zahl an Subsystemen zur Beeinflussung
bzw. Verbesserung des Fahrverhaltens bzw. der Fahrdynamik und zur
Verbesserung der Si cherheit stark zu. Auch bei den Subsystemen zur
Beeinflussung des Fahrverhaltens bzw. der Fahrdynamik ist der Trend
zu mehr Elektronik und Elektromechanik zu beobachten. Zu den Subsystemen
mit welchen das Fahrverhalten aktiv d.h. unabhängig vom Fahrer, beeinflußt werden
kann, zählen
das elektronische Bremssystem, das aktive Lenksystem, aktive bzw. semiaktive
Fahrwerkskomponenten sowie bei Fahrzeugen mit regelbaren Zwischengetrieben
auch das Antriebssystem. Jedes dieser Subsysteme soll das Fahrzeug
derart beeinflussen, dass sich Verbesserungen im Fahrverhalten ergeben.
Die Schwerpunkte der Regelalgorithmen liegen je nach Subsystem in unterschiedlichen
Bereichen (Sicherheit, Handling oder Komfort). Die Subsysteme werden
daher primär nur
für ihr
jeweiliges Regelziel bzw. ihr Haupteinsatzgebiet abgestimmt. Die
Einsatzgebiete bzw. die Schwerpunkte der einzelnen Subsysteme überlappen
sich jedoch in weiten Bereichen des fahrdynamischen Einsatzbereichs
von Fahrzeugen. Jedes dieser Subsysteme arbeitet für sich alleine
(Stand-alone), obwohl oft die gleichen fahrdynamischen Größen beeinflußt bzw,
eingeregelt werden sollen (
Der Erfindung liegt daher die Aufgabe zugrunde, die Funktionalität einer Fahrdynamikregelung zu erhöhen.Of the The invention is therefore based on the object, the functionality of a Increase vehicle dynamics control.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.These The object is solved by the features of claim 1.
Dadurch dass die Daten der Signalverteilung einer zentralen Fahrzustanderkennung zugeführt werden, dass die zentrale Ermittlungseinheit aus den Daten der Signalverteilung ein zentrales, gesamtheitliches Regelziel ermittelt und diese Daten bzgl. des zentralen Regelziels einer zentralen Stellgrößenverteilung zugeführt werden, die in einer interaktiven Kommunikation mit den Subsystemen diese Subsysteme derart ansteuert, dass das Regelziel von den Subsystemen am Fahrzeug umgesetzt wird, reduziert sich der Applikationsaufwand, vor allem für die gegenseitige Absicherung der einzelnen Subsysteme gegeneinander, und die funktionalen Einschränkungen für jedes der Subsysteme entfallen.Thereby that the data of the signal distribution of a central driving condition detection be fed that the central determination unit from the data of the signal distribution a central, holistic regulatory goal and this data with regard to the central control target of a central control value distribution supplied be in an interactive communication with the subsystems controls these subsystems such that the control target of the subsystems is implemented on the vehicle, reduces the application effort, especially for the mutual protection of the individual subsystems against each other, and the functional limitations for each the subsystems are eliminated.
Die Aufteilung erfolgt durch den zentralen Fahrzustandsregler bzw. die Stellgrößenverteilung selbst. Der Fahrzustandsregler bzw. die Stellgrößenverteilung ist ein Mehrgrößenregler und die entsprechende Aufteilung der Stellanforderungen auf die einzelnen Subsysteme basiert auf der Reglerauslegung (Reglerkonzept, Regleransatz, Regleralgorithmus) selbst, einem dem Regler vorgegebenen Gütekriterium bzw. Optimierungskriterium oder mittels abstimmbarer Gewichtungsfaktoren (Gewichtung entsprechend Stärke und Aktivierungsreihenfolge der Subsysteme). Beispielsweise kann es das Ziel dieser Aufteilung sein, dass bei geringer Instabilitätstendenz die Stabilitsierungsanforderung aus Komfortgründen erst auf das Fahrwerk und die Lenkung verteilt werden. Bei größerer Instabilitätstendenz sind zusätzlich noch die Bremse bzw. der Antriebsstrang berücksichtigen. Aus dieser Zielvorgabe lassen sich je nach Regleransatz ein Gütekriterium oder auch entsprechende Gewichtungsfaktoren für den Reglerentwurf bzw. den Regler ableiten.The Division takes place by the central driving state controller or the Command value distribution itself. The driving state controller or the manipulated variable distribution is a multi-variable controller and the corresponding distribution of the setting requirements on the individual Subsystems is based on the controller design (controller concept, controller approach, Controller algorithm) itself, a quality criterion specified for the controller or optimization criterion or by means of tunable weighting factors (Weighting according to strength and activation order of the subsystems). For example, can It should be the goal of this division, that with low instability tendency the stabilization requirement for reasons of comfort first on the chassis and the steering will be distributed. For greater instability tendency are additional take the brake or powertrain into consideration. For this purpose Depending on the controller approach, a quality criterion or equivalent can be selected Weighting factors for derive the controller design or the controller.

Vorteile der ErfindungAdvantages of invention
Das Zusammenfassen aller Regelfunktionen der einzelnen Aktuatoren in einem zentralen Fahrdynamikregelalgorithmus (integrierter Ansatz) hat gegenüber der Stand-Alone Variante diverse Vorteile sowohl fahrdynamisch als auch topologisch bzw. systemtechnisch:
- • Die verschiedenen Subsysteme bzw. intelligente Aktuatoren werden beim integrierten Ansatz von einem in sich geschlossenen Regelalgorithmus angesteuert. Somit ist das harmonische Zusammenspiel der einzelnen intelligenten Aktuatoren strukturell gesichert. Die Regelung des Fahrzustands ist gesichert, da sich die einzelnen intelligenten Aktuatoren nicht gegenseitig negativ beeinflussen können.
- • Die Möglichkeit zur Erweiterung des zentralen Fahrdynamikreglers um neue intelligente Aktuatoren ist einfach, da der Komplexitätszuwachs bescheiden ist.
- • Die gegenseitige Berücksichtigung der intelligenten Aktuatoren im Regelansatz resultiert in geringerem Applikationsaufwand (bei den Stand-alone Subsystemen müssen diese durch Fahrversuche gegeneinander abgesichert werden). Bei Erweiterungen des Stand-Alone Subsystemnetzes steigt die Komplexität ernorm an, was sich vor allem in einem stark zunehmenden Applikationsaufwand äußert.
- • Die zentrale Vernetzung der einzelnen intelligenten Aktuatoren im Regelansatz resultiert in einer geringen Buslast und wenigen physikalischen Schnittstellen zwischen dem Zentralrechner und den intelligenten Aktuato ren. Würden die Stand-Alone Subsysteme „vernetzt", so würde dies zu einem nur schwer kontrollierbaren und pflegbaren Kommunikationsaufkommen zwischen den Stand-Alone Subsystemen führen.
- • Die Verlagerung und Zusammenfassung bzw. Integration aller Regelfunktionen, Fahrzustandserkennungen und Fahrerinterpretationen von den Subsystemen in ein zentrales Steuergerät führt zu Kosteneinsparungen. Die einzelnen intelligenten Aktuatoren benötigen für das Ausführen ihrer Grundfunktionen (Steuerungen) weniger Rechenleistung. Somit können bei den intelligenten Aktuatoren günstigere und leistungsärmere Recheneinheiten mit weniger physikalischem Speicherbedarf zum Einsatz kommen.
- • Der Aufwand für die Erweiterung und Pflege der gesamten im Fahrzeug vorhandenen Software reduziert sich, da nicht mehr wie bei den Stand-alone Subsystemen für jedes Subsystem eigene Regelalgorithmen, eine Fahrzustandserfassung und Fahrerwunscherkennung nötig sind. Die Regelalgorithmen, die Fahrzustandserfassung und die Fahrerwunscherkennung sind beim integrierten Ansatz nur einmal zentral zu erweitern und pflegen.
- • Klare und eindeutige Trennung von Grundfunktionen (Steuerungen) und fahrdynamischen Regelfunktionen (Einregeln von Fahrzustandsgrößen mittels Rückführung von fahrdynamisch relevanten Größen wie beispielsweise der Gierrate, Querbeschleunigung, Schwimmwinkel, etc.).
- • The various subsystems or intelligent actuators are used in the integrated approach of a self-contained control algorithm driven. Thus, the harmonious interaction of the individual intelligent actuators is structurally secured. The control of the driving state is ensured because the individual intelligent actuators can not influence each other negatively.
- • The ability to add new intelligent actuators to the central vehicle dynamics controller is simple, as the complexity gain is modest.
- • The mutual consideration of the intelligent actuators in the control approach results in less application effort (in the case of the stand-alone subsystems, these must be secured against each other by road tests). In the case of extensions of the stand-alone subsystem network, the complexity increases enormously, which manifests itself above all in a strongly increasing application effort.
- • The central networking of the individual intelligent actuators in the control approach results in a low bus load and few physical interfaces between the central computer and the intelligent actuators. If the stand-alone subsystems were "networked", this would lead to a difficult to control and maintain communication volume between lead the stand-alone subsystems.
- • The relocation and integration or integration of all control functions, driving condition detection and driver interpretation from the subsystems into a central control unit leads to cost savings. The individual intelligent actuators require less computing power to perform their basic functions (controls). Thus, the intelligent actuators cheaper and lower-power computing units with less physical memory requirements can be used.
- • The effort for the expansion and maintenance of the entire existing software in the vehicle is reduced, since no longer as for the stand-alone subsystems for each subsystem own control algorithms, driving condition detection and driver desiring are necessary. The control algorithms, the driving condition detection and the driver request detection are only once to extend and maintain centrally in the integrated approach.
- • Clear and unambiguous separation of basic functions (controls) and vehicle dynamics control functions (adjustment of driving state variables by means of feedback of variables relevant to driving dynamics such as the yaw rate, lateral acceleration, slip angle, etc.).
