Abstract
Description
Die Erfindung betrifft ein Antriebssystem für ein Kraftfahrzeug, mit mindestens zwei unabhängig voneinander angetriebenen Achsen, mindestens einem Elektroantrieb, mindestens einer Steuereinrichtung mit mindestens einer Leistungselektronik und mit einer Energiespeicheranordnung. The invention relates to a drive system for a motor vehicle, with at least two independently driven axles, at least one electric drive, at least one control device with at least one power electronics and with an energy storage device.
Ein derartiges Antriebssystem ist beispielsweise aus der
Der Erfindung liegt daher die Aufgabe zugrunde, ein Antriebssystem zu schaffen, das vor dem Hintergrund von optimalen fahrdynamischen Bedingungen und einer optimalen Stabilitätssteuerung des Kraftfahrzeuges eine energie-effiziente Antriebsmomentverteilung gewährleistet. The invention is therefore based on the object to provide a drive system that ensures an energy-efficient drive torque distribution against the background of optimal driving dynamics conditions and optimal stability control of the motor vehicle.
Diese Aufgabe wird dadurch gelöst, dass die Steuereinrichtung zumindest ein Antriebsregelmodul und ein Traktionsregelmodul aufweist, wobei das Antriebsregelmodul jeweils ein maximales Antriebs-Teilmomentpotential für die erste Antriebsachse und die zweite Antriebsachse vorsieht, und ein vom Fahrer angefordertes Gesamtantriebsmoment ermittelt, wobei durch das Traktionsregelmodul abhängig von Fahrzeugbetriebsparametern mindestens ein Antriebsachsen-Teilmomentbereich ermittelbar ist, der an das Antriebsregelmodul übermittelbar ist, wobei das Antriebsregelmodul Antriebsachsen-Teilmomente innerhalb von Antriebsachsen-Teilmomentbereichen für die erste und zweite Antriebsachse ermittelt, derart, dass diese über die Leistungselektronik und die entsprechenden Antriebseinrichtungen an die erste und zweite Antriebsachse zu übertragen sind. Durch das Vorsehen eines Antriebsregelmoduls und eines Traktionsregelmoduls kann auf einfache steuertechnische Art und Weise gewährleistet werden, dass vor dem Hintergrund von fahrdynamischen Voraussetzungen ein optimaler energie-effizienter Fahrbetrieb gewährleistet ist. Hierbei ist es insbesondere vorteilhaft, wenn der Antriebsachsen-Teilmomentbereich für die zweite Antriebsachse durch das Traktionsregelmodul ermittelbar ist, und der Antriebsachsen-Teilmomentbereich für die erste Antriebsachse durch das Antriebsregelmodul ableitbar ist. In einer vorteilhaften Ausführungsform können durch das Traktionsregelmodul die Antriebsachsen-Teilmomentbereiche hinsichtlich der Bereichsbreite anpassbar sein. Dies kann in besonderen fahrdynamischen Situationen dazu führen, dass die Bereichsbreite auf ein Minimum beschränkt ist, was dazu führt, dass das Traktionsregelmodul Antriebsachsen-Teilmomente vorgibt. This object is achieved in that the control device has at least one drive control module and a traction control module, wherein the drive control module each provides a maximum drive torque share potential for the first drive axle and the second drive axle, and determines a requested by the driver total drive torque, wherein the traction control module depending on At least one drive axle sub-torque range can be determined, the drive control module determines drive axle part moments within the drive axle sub-torque ranges for the first and second drive axle, such that these on the power electronics and the corresponding drive means to the first and second drive axle are to be transmitted. By providing a drive control module and a traction control module can be ensured in a simple tax-technical way that against the background of dynamic driving conditions optimal energy-efficient driving is guaranteed. In this case, it is particularly advantageous if the drive axle partial torque range for the second drive axle can be determined by the traction control module, and the drive axle partial torque range for the first drive axle can be derived by the drive control module. In an advantageous embodiment, the traction control module allows the drive axle partial torque ranges to be adaptable with respect to the range width. In special driving dynamic situations, this can lead to the area width being restricted to a minimum, which leads to the traction control module specifying drive axle partial torques.
In einer weiteren vorteilhaften Ausführungsform, die besonders für eine sportliche Fahrdynamik geeignet ist, sind die erste Antriebsachse als Hinterradachse und die zweite Antriebsachse als Vorderradachse ausgebildet. Hierbei kann in vorteilhafter Weise ein zweiter Elektroantrieb vorgesehen sein, der antriebstechnisch mit der ersten Antriebsachse verbunden ist. In a further advantageous embodiment, which is particularly suitable for sporty driving dynamics, the first drive axle is designed as a rear wheel axle and the second drive axle as a front wheel axle. In this case, a second electric drive can be provided in an advantageous manner, which is drivingly connected to the first drive axle.
Der erste Elektroantrieb kann über ein Ein-Gang-Kupplungsgetriebe mit der zweiten Antriebsachse verbunden sein, um auf einfache Weise bei Überschreitung einer Grenzdrehzahl der ersten Antriebsachse entkuppelt zu werden. The first electric drive may be connected via a single-speed clutch transmission with the second drive axle to be decoupled in a simple manner when exceeding a limit speed of the first drive axle.
In einer weiteren vorteilhaften Ausführungsform ist das Kupplungsgetriebe für die erste Antriebsachse als Doppelkupplungsgetriebe ausgeführt. Durch ein derartiges Doppelkupplungsgetriebe kann der Wirkungsgrad hinsichtlich Verbrauch und Emissionen noch einmal verbessert werden, wobei ohne Zugkraftunterbrechung geschaltet werden kann, was wiederum einer sportlichen Fahrweise zu Gute kommt. Die Erfindung wird ebenfalls durch ein Verfahren zum Betrieb eines derartigen Antriebssystems dadurch gelöst, dass in einem ersten Schritt durch das Antriebsregelmodul Antriebs-Teilmomentpotentiale für die erste und die zweite Antriebsachse bestimmt werden und an das Traktionsregelmodul übermittelt werden, in einem zweiten Schritt durch das Antriebsregelmodul in Abhängigkeit des Fahrerwunsches ein Gesamtantriebsmoment ermittelt wird und dieses an das Traktionsregelmodul übermittelt wird, in einem dritten Schritt durch das Traktionsregelmodul ein zweiter Antriebsachsen-Teilmomentbereich für die zweite Antriebsachse ermittelt wird und an das Antriebsregelmodul übermittelt wird, in einem vierten Schritt durch das Antriebsregelmodul ein erster Antriebsachsen-Teilmomentbereich für die erste Antriebsachse vom zweiten Antriebsachsen-Teilmomentbereich für die zweite Antriebsachse abgeleitet wird, in einem fünften Schritt die Antriebsachsen-Teilmomente festgelegt und an die für die jeweiligen Antriebsachsen zuständige Leistungselektronik übermittelt werden. In a further advantageous embodiment, the clutch transmission for the first drive axle is designed as a double-clutch transmission. By such a dual-clutch transmission, the efficiency in terms of consumption and emissions can be improved once again, which can be switched without interruption of traction, which in turn comes to a sporty driving style. The invention is likewise achieved by a method for operating such a drive system in that, in a first step, drive partial torque potentials for the first and second drive axles are determined by the drive control module and transmitted to the traction control module, in a second step by the drive control module Depending on the driver's request, a total drive torque is determined and this is transmitted to the traction control module, in a third step by the traction control module a second drive axle sub-torque range for the second drive axle is determined and transmitted to the drive control module, in a fourth step by the drive control module, a first drive axles Partial torque range for the first drive axle is derived from the second drive axle part torque range for the second drive axle, in a fifth step, the drive axle part moments and fixed to the for the j eweiligen Drive axes responsible power electronics are transmitted.
In vorteilhafter Weise können nach dem vierten Schritt aufgrund von fahrdynamischen Parametern die Antriebsachsen-Teilmomentbereiche hinsichtlich der Bereichsbreite angepasst werden. Auch kann durch das Traktionsregelmodul über einen Gradienten X % / sec das Antriebsachsen-Teilmoment innerhalb eines Antriebsachsen-Teilmomentbereiches angepasst werden. Advantageously, the drive axle partial torque ranges can be adjusted with respect to the range width after the fourth step due to driving dynamics parameters. Also, by the traction control module via a gradient X% / sec, the drive axle partial torque can be adjusted within a drive axle partial torque range.
Die Erfindung wird nachfolgend anhand der Zeichnung näher erläutert, hierbei zeigt: The invention will be explained in more detail with reference to the drawing, in which:
