Abstract
Description
Die Erfindung betrifft ein Verfahren zur Steuerung und/oder Regelung einer elektrischen Maschine in einem Antriebsstrang gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a method for controlling and / or regulating an electric machine in a drive train according to the preamble of patent claim 1.
Die
Der Erfindung liegt die Aufgabe zugrunde, ein verbessertes Verfahren zur Steuerung und/oder Regelung einer Kupplung in einem Antriebsstrang eines Hybridfahrzeuges anzugeben.The invention has for its object to provide an improved method for controlling and / or regulating a clutch in a drive train of a hybrid vehicle.
Hinsichtlich des Verfahrens wird die Aufgabe durch die im Anspruch 1 angegebenen Merkmale gelöst.With regard to the method, the object is achieved by the features specified in claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Beim Verfahren zur Steuerung und/oder Regelung einer elektrischen Maschine in einem Antriebsstrang eines Elektro- oder Hybridfahrzeugs wird während eines Bremsvorgangs eine Drehmomentabgabe der elektrischen Maschine erfindungsgemäß derart gesteuert und/oder geregelt, dass ein vom Antriebsstrang auf ein abzubremsendes Antriebsrad übertragenes Drehmoment auf Null gesetzt ist. Dadurch sind vorteilhafterweise durch die entsprechende Steuerung und/oder Regelung der Drehmomentabgabe der elektrischen Maschine alle im Antriebsstrang auftretender Rotationsträgheitsmomente während eines Bremsvorgangs kompensierbar. Somit ist eine Reibbremse, welche das Bremsmoment am abzubremsenden Antriebsrad erzeugt, entlastet und schneller, sowie genauer aktuierbar.In the method for controlling and / or regulating an electric machine in a drive train of an electric or hybrid vehicle, a torque output of the electric machine is controlled and / or regulated in accordance with the invention during a braking operation such that a torque transmitted from the drive train to a drive wheel to be braked is set to zero , As a result, all rotational inertia torques occurring in the drive train can advantageously be compensated during a braking operation by the corresponding control and / or regulation of the torque output of the electric machine. Thus, a friction brake, which generates the braking torque on the drive wheel to be braked, relieved and faster, and more accurate actuated.
Dadurch sind insbesondere so genannte Antiblockier-Bremsungen feinfühliger, d. h. im Bereich des optimalen Schlupfwertes, aktuierbar, so dass deren Bremsweg verringerbar und eine Fahrsicherheit des Fahrzeugs erhöht ist.As a result, in particular so-called anti-lock braking is more sensitive, d. H. in the range of the optimum slip value, actuatable, so that their braking distance can be reduced and driving safety of the vehicle is increased.
Weiterhin ist mittels des erfindungsgemäßen Verfahrens auf Grund der verringerten Belastung eine Lebensdauer der Reibbremse signifikant erhöht. Daraus resultierend sind die Wartungs- und/oder Reparaturkosten der Reibbremse verringert.Furthermore, a lifetime of the friction brake is significantly increased by means of the method according to the invention due to the reduced load. As a result, the maintenance and / or repair costs of the friction brake are reduced.
Besonders vorteilhafterweise ist durch die verringerte Belastung der Reibbremse eine Feinstaubemission selbiger verringert.Particularly advantageously, the particulate matter emission is reduced by the reduced load of the friction brake selbiger.
In einer besonders vorteilhaften Ausführungsvariante kann ein am abzubremsenden Antriebsrad aufzubringendes Bremsmoment teilweise oder vollständig mittels der elektrischen Maschine erzeugt werden, so dass während des Bremsvorgangs elektrische Energie erzeugbar ist.In a particularly advantageous embodiment variant, a braking torque to be applied to the drive wheel to be braked can be generated partially or completely by means of the electric machine, so that electrical energy can be generated during the braking operation.
In einer weiteren vorteilhaften Ausführungsvariante kann die Steuerung und/oder Regelung der elektrischen Maschine in Abhängigkeit von auftretenden Schwingungen im Antriebsstrang durchgeführt werden. Dadurch sind vorteilhafterweise für Fahrzeuginsassen während des Bremsvorgangs wahrnehmbare Schwingungen im Antriebsstrang verringerbar, so dass ein Fahrkomfort des Fahrzeugs erhöht ist.In a further advantageous embodiment variant, the control and / or regulation of the electrical machine can be carried out as a function of occurring vibrations in the drive train. As a result, noticeable oscillations in the drive train can advantageously be reduced for vehicle occupants during the braking process, so that the ride comfort of the vehicle is increased.
Ausführungsbeispiele der Erfindung werden im Folgenden anhand von Zeichnungen näher erläutert.Embodiments of the invention are explained in more detail below with reference to drawings.

Das erfindungsgemäße Verfahren betrifft eine Steuerung und/oder Regelung einer elektrischen Maschine
Der Antriebsstrang
Die Antriebswelle
In einer zweiten Ausführungsform ist der Antriebsstrang
In einer alternativen Ausführungsvariante treibt die elektrische Maschine
In einem solchen Antriebsstrang
Bei einem Bremsvorgang muss deshalb eine herkömmliche Radbremse diese Rotationsträgheitsmomente des Antriebsstrangs
Insbesondere wenn ein plötzliches Bremsereignis auftritt und das Antiblockiersystem des Fahrzeugs aktiviert wird, bewirkt die auf die mittels der Reibbremse
Dabei ist das mittels des Antriebsrads
Dabei steigt die übertragbare Längskraft FL ausgehend vom Nullpunkt steil an und erreicht ein Maximum M. Im weiteren Verlauf sinkt die übertragbare Längskraft FL allmählich ab. Der Bereich zwischen Nullpunkt und Maximum M wird als stabiler Bereich einer Bremsung bezeichnet, da das Fahrzeug in diesem Bereich kontrollierbar bleibt und Lenkbewegungen folgt. Der Bereich zwischen dem Maximum M und dem maximalen Längsschlupf s wird als instabiler Bereich bezeichnet, da das Fahrzeug in diesem Bereich unkontrollierbar ist und Lenkbewegungen nicht folgt.In this case, the transmittable longitudinal force F L rises steeply from the zero point and reaches a maximum M. In the further course, the transmittable longitudinal force F L gradually decreases. The range between zero and maximum M is referred to as a stable range of braking because the vehicle remains controllable in this range and follows steering movements. The range between the maximum M and the maximum longitudinal slip s is referred to as an unstable range because the vehicle is uncontrollable in this range and does not follow steering movements.
Droht ein Rad zu blockieren, d. h. der Wert des Längsschlupfes s überschreitet einen vorgebbaren oberen Schwellwert Amax, wird das betreffende Rad nicht weiter abgebremst, bis ein weiterer vorgebbaren unterer Schwellwert Arm erreicht ist. Der Bereich zwischen den Schwellwerten Amax und Amin wird als Regelbereich A bezeichnet.If a wheel threatens to block, ie the value of the longitudinal slip s exceeds a predefinable upper threshold value A max , the relevant wheel is not braked further until another predefinable lower arm threshold is reached. The range between the threshold values A max and A min is referred to as control range A.

Dadurch nimmt die Reibbremse
Durch die entsprechende Steuerung und/oder Regelung der Drehmomentabgabe der elektrischen Maschine
Dadurch sind insbesondere so genannte Antiblockier-Bremsvorgänge feinfühliger, d. h. im Bereich des Maximums M und somit des optimalen Längsschlupfes s, aktuierbar, so dass deren Bremsweg verringerbar und eine Fahrsicherheit des Fahrzeugs erhöht ist.As a result, in particular so-called anti-lock braking processes are more sensitive, d. H. in the region of the maximum M and thus of the optimal longitudinal slip s, actuatable, so that their braking distance can be reduced and driving safety of the vehicle is increased.
Ziel der erfindungsgemäßen Steuerung und/oder Regelung der Drehmomentabgabe der elektrischen Maschine
Weiterhin ist mittels des erfindungsgemäßen Verfahrens auf Grund der verringerten Belastung eine Lebensdauer der Reibbremse
In einer besonders vorteilhaften Ausführungsvariante kann ein am abzubremsenden Antriebsrad
In einer weiteren vorteilhaften Ausführungsvariante kann die Steuerung und/oder Regelung der elektrischen Maschine
Vorteilhaft werden die elektrische Maschine
Auch ist vorteilhaft das gemeinsame Steuergerät sowohl mit der elektrischen Maschine
Mit einem gemeinsamen Steuergerät und einer direkten Anbindung von Komponenten lassen sich mehrere komplexe Verfahren gut aufeinander abstimmen, wie hier ein Bremsvorgang, der auf die Räder abgestimmt ist und ein Erzeugen eines Gegenmoments zur Trägheit des Antriebstranges, um damit die Bremse zu entlasten und eine Bremskraft feiner abstimmen zu können.With a common control unit and a direct connection of components, several complex procedures can be well coordinated, such as a braking process, which is tuned to the wheels and generating a counter-torque to the inertia of the drive train to relieve the brake and a fine braking force to be able to vote.
