Abstract
Description
Die Erfindung betrifft eine Antriebsvorrichtung für ein Fahrzeug nach dem Oberbegriff des Patentanspruches 1 sowie ein Verfahren zum Betreiben eines Fahrzeugs mit einer solchen Antriebsvorrichtung nach dem Patentanspruch 16.The invention relates to a drive device for a vehicle according to the preamble of claim 1 and a method for operating a vehicle with such a drive device according to claim 16.
Bei Fahrzeugen mit Allradantrieb kann beispielsweise die Hinterachse über eine Elektromaschine elektrisch angetrieben werden. Der Vorderachsantrieb kann beispielhaft durch eine Brennkraftmaschine gegebenenfalls in Verbindung mit einer weiteren Elektromaschine realisiert sein. In der hier eingesetzten Elektromaschine sind üblicherweise Permanentmagnete verbaut, mit denen für eine optimale Beschleunigung ein hohes Anfahrmoment und eine hohe Leistungsdichte realisierbar ist.In vehicles with four-wheel drive, for example, the rear axle can be electrically driven by an electric motor. The front-axle drive can be realized, for example, by an internal combustion engine, optionally in conjunction with another electric machine. In the electric machine used here usually permanent magnets are installed with which a high starting torque and a high power density can be realized for optimal acceleration.
Aus der
In einer solchen Antriebsvorrichtung können verschiedene Fehlerfälle auftreten. So kann aufgrund eines Bauteil- oder Stromversorgungsausfalls die Elektromaschine im laufenden Fahrbetrieb ausfallen. Außerdem kann im Motorsteuergerät, In einer Fahrdynamikregelung und/oder in der Leistungselektronik der jeweiligen Elektromaschine aufgrund fehlerhafter Betriebszustände ein Fehlersignal generiert werden. Dies kann wiederum zu einer Stilllegung der Elektromaschine führen.In such a drive device, various error cases can occur. Thus, due to a component or power supply failure, the electric machine fail while driving. In addition, an error signal can be generated in the engine control unit, in a vehicle dynamics control and / or in the power electronics of the respective electric machine due to faulty operating states. This in turn can lead to a shutdown of the electric machine.
Die stillgelegte Elektromaschine erzeugt insbesondere bei darin verbauten Permanentmagneten hohe Schleppmomente, die die Fahrzeugräder bremsen. Dadurch können sich wiederum Instabile Fahrzustände ergeben, bei denen das Fahrzeugheck ausbrechen kann.The disengaged electric machine generates high drag torques, which brake the vehicle wheels, especially in permanent magnets installed therein. This can in turn result in unstable driving conditions in which the rear of the vehicle can break out.
Die Aufgabe der Erfindung besteht darin, eine Antriebsvorrichtung für ein Fahrzeug sowie ein Verfahren zum Betreiben der Antriebsvorrichtung bereitzustellen, bei dem die Fahrzeugsicherheit in einem Fehlerfall verbessert ist.The object of the invention is to provide a drive device for a vehicle and a method for operating the drive device, in which the vehicle safety is improved in the event of a fault.
Die Aufgabe ist durch die Merkmale des Patentanspruches 1 oder des Patentanspruches 16 gelöst. Bevorzugte Weiterbildungen der Erfindung sind in den Unteransprüchen offenbart.The object is solved by the features of claim 1 or claim 16. Preferred embodiments of the invention are disclosed in the subclaims.
Gemäß dem kennzeichnenden Teil des Patentanspruches 1 weist die Antriebsvorrichtung eine Fehlererkennungseinrichtung auf, mit der ein Fehlerfall der Antriebsvorrichtung erfassbar ist und mit der bei Erfassung eines solchen Fehlerfalls das Schaltelement in seine Offenstellung gesteuert wird. Bei fehlerhaftem Betrieb des Fahrzeugs, insbesondere bei einem in der Elektromaschine auftretenden Fehlerfall, wird daher die Elektromaschine automatisch von den Antriebsrädern entkoppelt. Dadurch wird kein Schleppmoment erzeugt, das zu instabilen Fahrzuständen führen könnte. Darüberhinaus entstehen bei einer fehlerfallbedingt stillgelegten Elektromaschine keine Leistungsverluste.According to the characterizing part of claim 1, the drive device has an error detection device with which a fault of the drive device can be detected and with the detection of such a fault, the switching element is controlled in its open position. In the case of faulty operation of the vehicle, in particular in the case of an error occurring in the electric machine, the electric machine is therefore automatically decoupled from the drive wheels. As a result, no drag torque is generated, which could lead to unstable driving conditions. In addition, no power losses occur in the case of a faulty shutdown electric machine.
Unter einem Fehlerfall sind ein Bauteil- oder Stromversorgungsausfall an der Elektromaschine oder jeglicher anderer Betriebszustand zu verstehen, der in der Antriebsvorrichtung zur Generierung eines Fehlersignals führt.An error case is a component or power supply failure on the electric machine or any other operating state to understand that leads to the generation of an error signal in the drive device.
Derartige Fehlersignale können in der Fehlererkennungseinrichtung ausgewertet werden und dort mit vorab definierten Fehlerzuständen verglichen werden. Nach Erfassung eines für die Fahrzeugsicherheit relevanten Fehlerfalls steuert die Fehlererkennungseinrichtung das Schaltelement in seine Offenstellung. Die Fehlererkennungseinrichtung kann alternativ auch in einem der vorhandenen Steuergeräte, zum Beispiel Motorsteuergerät, integriert sein.Such error signals can be evaluated in the error detection device and compared there with previously defined error conditions. After detecting an error case relevant to vehicle safety, the error detection device controls the switching element in its open position. Alternatively, the fault detection device can also be integrated in one of the existing control devices, for example engine control unit.
Ein solcher relevanter Fehlerfall kann der Ausfall des Lenkwinkelsensors sein. Dadurch erhält die Fahrdynamikregelung keine Informationen darüber, ob das Lenkverhalten des Fahrers einen ESP-Eingriff erforderlich macht oder nicht. Um in diesem Fall instabile Fahrzustände zu vermeiden, kann die erfindungsgemäße Fehlererkennungseinrichtung die Fahrzeugräder von der Elektromaschine entkoppeln.Such a relevant error case may be the failure of the steering angle sensor. As a result, the vehicle dynamics control receives no information about whether the driver's steering behavior requires an ESP intervention or not. In order to avoid unstable driving conditions in this case, the fault detection device according to the invention can decouple the vehicle wheels from the electric machine.
Das Schaltelement kann mittels eines Stellantriebes zwischen der Offen- und Geschlossenstellung verstellt werden. Der Stellantrieb kann beispielhaft mit elektrischer, pneumatischer oder hydraulischer Energie versorgt werden.The switching element can be adjusted by means of an actuator between the open and closed position. The actuator can be supplied by way of example with electrical, pneumatic or hydraulic energy.
Um dabei selbst bei Ausfall des Bordnetzes eine automatische Öffnung des Schaltelementes im Fehlerfall zu gewährleisten, kann das Schaltelement im energielosen Zustand automatisch in seiner Offenstellung verstellt sein. Beim Ausfall einer elektrischen Stromversorgung kann daher das Schaltelement automatisch stromlos offen geschaltet sein.In order to ensure an automatic opening of the switching element in case of failure even in case of failure of the electrical system, the switching element can be automatically adjusted in the de-energized state in its open position. In case of failure of an electrical power supply, therefore, the switching element can be automatically switched off normally open.
Zur Anpassung der von der Elektromaschine erzeugten Motordrehzahl an das Fahrzeugrad kann im Antriebsstrang zwischen der Elektromaschine und dem Fahrzeugrad eine Getriebestufe angeordnet sein. Der Hinter- oder Vorderachsantrieb kann eine zentrale Elektromaschine aufweisen, die über ein Achsdifferenzial mit zu den linken und rechten Fahrzeugrädern führende Gelenkwellen verbunden ist. Das Schaltelement ist bevorzugt in einer Momentenflussrichtung nach der Getriebestufe der Elektromaschine angeordnet sein, wodurch in der Offenstellung die Elektromaschine zusammen mit der Getriebestufe ausgekuppelt ist. To adapt the engine speed generated by the electric motor to the vehicle wheel, a gear stage may be arranged in the drive train between the electric machine and the vehicle wheel. The rear or front axle drive can have a central electric machine, which is connected via an axle differential with leading to the left and right vehicle wheels drive shafts. The switching element is preferably arranged in a torque flow direction after the gear stage of the electric machine, whereby in the open position, the electric machine is disengaged together with the gear stage.
Dabei kann zwischen dem zentralen Achsdifferenzial und jedem der Fahrzeugräder jeweils ein Schaltelement angeordnet sein, das jeweils von der Fehlererkennungseinrichtung ansteuerbar ist. Bei dieser Ausführungsform sind daher die Fahrzeugräder nicht nur von der Elektromaschine und der Getriebestufe, sondern auch vom zentralen Achsdifferenzial abgekoppelt.In this case, in each case a switching element can be arranged between the central axle differential and each of the vehicle wheels, which can be controlled by the error detection device. In this embodiment, therefore, the vehicle wheels are decoupled not only from the electric machine and the gear stage, but also from the central axle differential.
Die Fehlererkennungseinrichtung kann über Signalleitungen mit Sensoreinrichtungen verbunden sein, die einen Fehlerfall im Fahrzeug erfassen können. Die Signalleitungen können als Datenbus technisch realisiert sein. Als Sensoreinrichtung im Sinne der Erfindung wird beispielsweise ein Motorsteuergerät einer etwa an der Vorderachse vorgesehenen Brennkraftmaschine, ein Gesamtantriebsmanagement oder eine Fahrdynamikregelung verstanden. Alternativ kann die Sensoreinrichtung eine Strommesseinrichtung der Leistungselektronik Elektromaschine sein, die bei Erfassung eines Fehlerstroms ein Fehlersignal erzeugt. Das Fehlersignal wird dann zur Fehlererkennungseinrichtung geleitet, die auf der Grundlage des Fehlersignals das Schaltelement in die Offenstellung steuert.The error detection device can be connected via signal lines with sensor devices that can detect a fault in the vehicle. The signal lines can be technically realized as a data bus. As a sensor device according to the invention, for example, an engine control unit of an approximately provided on the front axle internal combustion engine, a total drive management or a vehicle dynamics control understood. Alternatively, the sensor device may be a current measuring device of the power electronics electric machine, which generates an error signal upon detection of a fault current. The error signal is then passed to the error detection device, which controls the switching element to the open position based on the error signal.
Die Antriebsvorrichtung kann neben der erfindungsgemäßen Fehlererkennungseinrichtung eine separat davon arbeitende elektronische Steuereinrichtung aufweisen, mit der etwa auf Grundlage eines Fahrerwunsches ein Antriebsmoment zum Antrieb des Fahrzeugs bestimmt wird. Die Steuereinrichtung kann darüberhinaus in bekannter Weise mit einer Fahrdynamikregelung in Verbindung sein und auf der Grundlage der von dieser Regelung erhaltenen Eingangsparameter eine Momentenverteilung zwischen der Vorder- und Hinterachse steuern.In addition to the error detection device according to the invention, the drive device may have an electronic control device operating separately therefrom, with which a drive torque for driving the vehicle is determined on the basis of a driver request, for example. The control device can moreover be in a known manner in connection with a vehicle dynamics control and control a torque distribution between the front and rear axle on the basis of the input parameters obtained from this control.
Die Elektromaschine kann bevorzugt einen gehäusefesten Stator sowie einen Rotor aufweisen, der mit einer Abtriebshohlwelle gebildet ist. Um eine in der Fahrzeuglängsrichtung vorteilhaft kurze Bauweise zu erreichen, kann durch die Hohlabtriebswelle sowie den Rotor der Elektromaschine eine mit dem Fahrzeugrad verbundene Gelenkwelle geführt sein, die die Fahrzeugachse bildet.The electric machine may preferably have a housing-fixed stator and a rotor which is formed with a hollow output shaft. In order to achieve an advantageously short construction in the vehicle longitudinal direction, a drive shaft connected to the vehicle wheel can be guided through the hollow output shaft and the rotor of the electric machine, which forms the vehicle axle.
Zur weiteren Bauraumreduzierung kann die der Elektromaschine zugeordnete Getriebestufe als ein Planetengetriebe ausgebildet sein, durch das die Gelenkwelle koaxial geführt ist. Im Vergleich zu einer Stirnradverzahnung kann das Planetengetriebe in der Fahrzeugquerrichtung mit wesentlich geringerer Baulänge eingebaut werden.To further reduce space, the electric machine associated gear stage may be formed as a planetary gear through which the propeller shaft is guided coaxially. Compared to a spur gear toothing, the planetary gear can be installed in the vehicle transverse direction with a much smaller overall length.
Die oben genannte Abtriebshohlwelle der Elektromaschine kann unmittelbar mit einem Eingangselement der Getriebestufe in Verbindung sein, insbesondere mit einem Sonnenrad des Planetengetriebes, das ebenfalls koaxial zur Gelenkwelle ausgerichtet ist. Entsprechend sind das Planetengetriebe und die Elektromaschine in der Fahrzeugquerrichtung in Reihe zueinander ausgerichtet.The abovementioned output hollow shaft of the electric machine can be directly connected to an input element of the gear stage, in particular with a sun gear of the planetary gear, which is likewise aligned coaxially with the propeller shaft. Accordingly, the planetary gear and the electric machine are aligned in the vehicle transverse direction in series with each other.
Das Ausgangselement der Getriebestufe kann in einer Ausführungsform über eine Zwischenhohlwelle unmittelbar mit dem Achsdifferenzial verbunden sein, mit dem das von der Elektromaschine generierte Antriebsmoment auf die beiden Fahrzeugräder der Fahrzeugachse aufgeteilt wird. In diesem Fall ist jeweils ein erfindungsgemäßes Schaltelement in Momentenflussrichtung nach dem Achsdifferenzial sowie vor der linken und vor der rechten Gelenkwelle eingeschaltet.In one embodiment, the output element of the gear stage can be connected directly to the axle differential via an intermediate hollow shaft, with which the drive torque generated by the electric machine is divided between the two vehicle wheels of the vehicle axle. In this case, an inventive switching element in the torque flow direction after the axle differential and in front of the left and before the right propeller shaft is turned on in each case.
Alternativ dazu kann die zwischen der Getriebestufe und dem Achsdifferenzial angeordnete Zwischenhohlwelle in zwei Teilhohlwellen aufgeteilt sein, die über das erfindungsgemäße Schaltelement trieblich miteinander verbindbar sind.Alternatively, arranged between the gear stage and the axle differential intermediate hollow shaft may be divided into two partial hollow shafts, which are drivingly connected to each other via the switching element according to the invention.
Erfindungsgemäß können somit die Elektromaschine, die Getriebestufe sowie das zumindest eine Schaltelement koaxial zu den Gelenkwellen der Fahrzeugachse angeordnet sein. Die Elektromaschine kann dabei in diesem Fall in der Fahrzeugquerrichtung in Reihe mit der Getriebestufe, dem Schaltelement sowie dem Ausgleichsdifferenzial geschaltet sein, wodurch eine besonders kompakte Anordnung sowohl in Fahrzeuglängs- als auch -querrichtung ermöglicht ist.Thus, according to the invention, the electric machine, the gear stage and the at least one switching element can be arranged coaxially with the cardan shafts of the vehicle axle. The electric machine can be connected in this case in the vehicle transverse direction in series with the gear stage, the switching element and the differential compensation, whereby a particularly compact arrangement in both vehicle longitudinal and transverse direction is possible.
Das erfindungsgemäß einsetzbare Schaltelement kann als eine an sich bekannte Klauenkupplung, eine Reibkupplung oder auch als eine Schiebehülse ausgeführt sein, mit der erfindungsgemäß die An- oder Abkupplung der Antriebsräder von der Elektromaschine durchführbar sind.The switching element which can be used according to the invention can be embodied as a per se known dog clutch, a friction clutch or as a sliding sleeve, with the present invention, the arrival or decoupling of the drive wheels of the electric machine can be performed.
