The additional load can be connected to an another stator winding and is the electrical heating unit for the exhaust catalyser, seats or rear screen.

Description

Die Erfindung betrifft ein Bordnetz mit einem Startergenerator in einem Kraftfahrzeug gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to an electrical system with a starter generator in a motor vehicle according to the preamble of claim 1.

Unter der Bezeichnung Startergenerator-Vorrichtungen sind beispielsweise aus der EP-0 103 821 Elektromaschinen bekannt, bei denen ein wicklungsloser Rotor einerseits über eine Trennkupplung mit der Kurbelwelle einer Brennkraftmaschine und andererseits mit der Eingangswelle eines Getriebes verbunden ist. Der Elektromaschinenrotor ist von einem Stator umgeben, dessen Wicklungen über eine Regeleinrichtung mit der Kraftfahr­ zeugbatterie oder anderen elektrischen Verbrauchern des Kraftfahrzeuges in Verbindung steht. In Abhängigkeit von der jeweiligen Betriebssituation kann die beschriebene Elektro­ maschine zum Anwerfen der stillstehenden Brennkraftmaschine oder als Generator zum Aufladen der Fahrzeugbatterie und zum Speisen des Bordnetzes genutzt werden.Under the name starter generator devices are for example from the EP-0 103 821 electrical machines are known in which a winding-free rotor is used on the one hand a clutch with the crankshaft of an internal combustion engine and on the other hand with the Input shaft of a transmission is connected. The electric machine rotor is from one Surround the stator, its windings via a control device with the motor vehicle battery or other electrical consumers of the motor vehicle in connection stands. Depending on the respective operating situation, the electrical described can machine for starting the stationary internal combustion engine or as a generator for Charge the vehicle battery and be used to power the vehicle electrical system.

Bei den bisher bekannten Fahrzeugbordnetzen ist es vorgesehen, daß die im generatori­ schen Betrieb erzeugte Wechselspannung in der Regeleinrichtung gleich gerichtet und so als Gleichspannung für das elektrische Versorgungsnetz in dem Kraftfahrzeug zur Verfügung gestellt wird. Durch die gestiegenen Anforderungen an die Abgasemission von Kraftfahrzeugen vor allem während der Kaltstartphase wurde vorgeschlagen, im Abgas­ katalysator eines Kraftfahrzeuges eine elektrische Heizung vorzusehen, mit der der Katalysator in deutlich kürzerer Zeit als bisher auf seine für den Abgasreinigungsprozeß optimale Temperatur bringbar ist. Die hohe Leistungsaufnahme einer solchen Katalysator­ heizung belastet aber das elektrische Bordnetz und insbesondere die Fahrzeugbatterie in dieser Startphase vor allem in der kalten Jahreszeit, so daß bei den üblichen, mit normalen Anlassern und Generatoren ausgerüsteten Kraftfahrzeuge eine deutlich höhere Batterie­ kapazität und/oder Generatorleistung erforderlich ist.In the previously known vehicle electrical systems, it is provided that the generatori AC operation generated in the control device rectified and so as DC voltage is available for the electrical supply network in the motor vehicle is provided. Due to the increased requirements for exhaust gas emissions from Motor vehicles, especially during the cold start phase, have been proposed in the exhaust gas catalytic converter of a motor vehicle to provide an electrical heater with which Catalyst in a significantly shorter time than before for its for the exhaust gas cleaning process optimal temperature can be brought. The high power consumption of such a catalyst however, heating loads the electrical system and in particular the vehicle battery this starting phase especially in the cold season, so that in the usual, with normal Motor vehicles equipped with starters and generators have a significantly higher battery capacity and / or generator power is required.

Vor diesem Hintergrund bestand die Aufgabe der Erfindung darin, für ein Kraftfahrzeug mit einer Startergenerator-Elektromaschine ein Kraftfahrzeugbordnetz vorzuschlagen, mit dem ein ohmscher Verbraucher insbesondere eine elektrische Katalysatorbeizung während der Warmlaufphase des Motors eines Kraftfahrzeuges problemlos betreibbar ist.Against this background, the object of the invention was for a motor vehicle propose a motor vehicle electrical system to a starter generator electric machine with which  an ohmic consumer in particular an electrical catalyst pickling during the Warm-up phase of the engine of a motor vehicle is easily operable.

Die Lösung dieser Aufgabe ergibt sich aus den kennzeichnenden Merkmalen des Anspruchs 1, während vorteilhafte Ausgestaltungen der Erfindung den Unteransprüchen entnehmbar sind.The solution to this problem results from the characterizing features of the claim 1, while advantageous embodiments of the invention can be found in the subclaims are.

Erfindungsgemäß ist also ein Kraftfahrzeugbordnetz vorgesehen, bei dem die Stator-Wick­ lung der Startergenerator-Maschine direkt mit einem zusätzlichen elektrischen Verbraucher, beispielsweise der Heizung für den Abgaskatalysator mittels einer gesonderten Zu­ schaltvorrichtung bei Bedarf verbindbar ist. Durch dieses Auskoppeln der ungeregelten Wechselspannung der Elektromaschine zum Betreiben von großen ohmschen Verbrau­ chern, vorzugsweise von einer Katalysatorheizung braucht die Gleichrichtungsleistung der Regelungseinrichtung nicht erhöht zu werden.According to the invention, therefore, a motor vehicle electrical system is provided in which the stator winding the starter generator machine directly with an additional electrical consumer, for example, the heater for the catalytic converter by means of a separate zu switching device can be connected if necessary. By decoupling the unregulated AC voltage of the electric machine for operating large ohmic consumption Chern, preferably from a catalyst heater needs the rectification power Control device not to be increased.

Bei einer derartigen Betriebsweise der Elektromaschine kann auch beispielsweise eine Heck- oder Frontscheibenheizung oder eine Sitzheizung des Kraftfahrzeuges sinnvoll zuge­ schaltet werden, da es sich in all diesen Fällen um ohmsche Verbraucher handelt, die keine Gleichspannungsversorgung benötigen.In such an operating mode of the electric machine, for example, a Rear or windscreen heater or a seat heater of the motor vehicle sensibly supplied be switched, since in all these cases it is ohmic consumers, which none Need DC power supply.

Die beschriebene Zuschaltvorrichtung kann demnach von einem separaten Steuergerät, von dem Anlasserschalter der Brennkraftmaschine oder von Betätigungsschaltern von ohmschen Verbrauchern betätigt werden. In einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, daß an der Startergenerator-Maschine zusätzliche Statoren vorgesehen sind, deren Wicklungen über Zuschaltvorrichtungen mit den ohmschen Verbrauchern direkt verbindbar sind. Dadurch kann auf einfache Weise die Generatorleistung erhöht werden.The connection device described can accordingly by a separate control unit, by the starter switch of the internal combustion engine or of ohmic actuation switches Be operated by consumers. In an advantageous embodiment of the invention provided that additional stators are provided on the starter generator machine, whose windings are directly connected to the ohmic consumers via connection devices are connectable. This allows the generator power to be increased in a simple manner.

Fig. 3 ein Bordnetz gemäß Fig. 2, aber mit zusätzlichem Stator für den ohmschen Verbraucher dargestellt. Fig. 3 shows an electrical system according to FIG. 2, but with an additional stator for the ohmic consumer.

In Fig. 1 ist demnach mit 1 eine Brennkraftmaschine bezeichnet, deren Kurbelwelle 6 über eine Trennkupplung 18 mit dem Rotor 4 einer Startergenerator-Elektromaschine 3 verbun­ den ist. Abtriebsseitig steht diese Elektromaschine 3 mit ihrem Rotor 4 über eine Kupplung 21 mit der Getriebeeingangswelle 7 eines Getriebes 2 in Verbindung. Der Rotor 4 der Elektromaschine 3 ist von einem Stator 5 umgeben, dessen Wicklungen über eine hier nicht dargestellte Regelvorrichtung 9 mit dem hier nicht dargestellten Bordnetz des Kraftfahr­ zeuges gekoppelt ist.In Fig. 1, 1 denotes an internal combustion engine, the crankshaft 6 verbun via a clutch 18 to the rotor 4 of a starter generator electric machine 3 is the. On the output side, this electrical machine 3 is connected with its rotor 4 via a clutch 21 to the transmission input shaft 7 of a transmission 2 . The rotor 4 of the electric machine 3 is surrounded by a stator 5 , the windings of which are coupled via a control device 9 (not shown here) to the vehicle electrical system (not shown) of the motor vehicle.

In Fig. 2 ist die Startergenerator-Kombination 3 stylisiert dargestellt. Der wicklungslose Rotor 4 erzeugt im generatorischen Betrieb bei der Drehung um seine Achse 19 in der Wicklung 8 des Stators 5 eine elektrische Wechselspannung, die in bekannter Weise in der Regelvorrichtung 9 zu einer Gleichspannung umgewandelt und der Fahrzeugbatterie 10 sowie den elektrischen Verbrauchern 11 des Kraftfahrzeuges zur Verfügung gestellt wird.In FIG. 2, the starter-generator combination is shown stylisiert 3. The winding-less rotor 4 generates an alternating electrical voltage in the winding 8 of the stator 5 in generator operation when rotating about its axis 19 , which is converted into a direct voltage in the control device 9 in a known manner and to the vehicle battery 10 and the electrical consumers 11 of the motor vehicle Is made available.

Zusätzlich ist eine Zuschaltvorrichtung 12 dargestellt, mit deren Hilfe die Wechselspannung der Elektromaschine 3 zu einem gesonderten ohmschen Verbraucher 15 ableitbar ist. Die Steuerung der Zuschaltvorrichtung 12 erfolgt direkt oder indirekt beispielsweise über den Anlasserschalter 16 der Brennkraftmaschine, ein gesondertes Steuergerät 17 oder anderen hier nicht dargestellten Betätigungsschaltern von leistungsstarken ohmschen Verbrauchern.In addition, a connection device 12 is shown, by means of which the AC voltage of the electric machine 3 can be derived to a separate ohmic consumer 15 . The connection device 12 is controlled directly or indirectly, for example, via the starter switch 16 of the internal combustion engine, a separate control device 17 or other actuation switches, not shown here, of powerful ohmic consumers.

In dem Ausführungsbeispiel gemäß Fig. 3 ist eine Elektromaschine 3 vorgesehen, die we­ nigstens einen Stator 5 aufweist, dessen Wicklungen 8 mit der Regelvorrichtung 9 zu Um­ wandlung der Wechselspannung der Elektromaschine 3 in Gleichspannung für die Verbrau­ cher 10 und 11 genutzt wird. Zudem verfügt die Elektromaschine 3 über mindestens einen weiteren separaten Stator 14, dessen Wicklung 20 über eine Zuschaltvorrichtung 13 mit dem ohmschen Verbraucher 15, beispielsweise der Katalysatorheizung oder einer Sitz- oder Scheibenheizung des Kraftfahrzeuges in Verbindung steht. Auch hier wird die Zuschaltvorrichtung 13 von einem gesonderten Steuergerät 17 oder nicht dargestellten Anlasser- oder Betätigungsschaltern betätigt. Bei dem Bordnetz nach dieser Fig. 3 ist ein größerer Bauteil- und Integrationsaufwand zur Herstellung eines solchen Bordnetzes notwendig, es erlaubt aber das separate Abgreifen von zusätzlicher elektrischer Leistung aus der Elektromaschine 3.In the embodiment according to FIG. 3, an electric machine 3 is provided, which we at least has a stator 5 , the windings 8 of which are used with the control device 9 to convert the AC voltage of the electric machine 3 into DC voltage for the consumers 10 and 11 . In addition, the electric machine 3 has at least one further separate stator 14 , the winding 20 of which is connected via a connection device 13 to the ohmic consumer 15 , for example the catalytic converter heater or a seat or window heater of the motor vehicle. Here too, the connection device 13 is actuated by a separate control device 17 or starter or actuation switches (not shown). In the on-board electrical system according to this FIG. 3, a larger component and integration effort is required to produce such an on-board electrical system, but it allows separate tapping of additional electrical power from the electric machine 3 .
