Description
Die Erfindung betrifft ein Kraftfahrzeug mit einer Schaltungsanordnung zur Kopplung von zwei ersten Spannungsanschlüssen einer ersten Seite mit zwei zweiten Spannungsanschlüssen einer zweiten Seite, an denen eine höhere Spannung anliegt, als an den ersten Spannungsanschlüssen, wobei die Schaltungsanordnung eine Drehfeldmaschine umfasst, die in einer Sternpunktschaltung bereitgestellt ist, deren Sternpunkt mit einem der ersten Spannungsanschlüsse gekoppelt ist, und von der eine Mehrzahl von Phasenausgängen jeweils über einen zwei Transistoren mit jeweils parallel geschalteten Inversdioden umfassenden Brückenzweig einer mehrphasigen Vollbrücke, welche in Abhängigkeit von der Betriebsart der Drehfeldmaschine, nämlich als Motor oder als Generator, als Wechselrichter oder als Gleichrichter betreibbar ist, sowohl mit einem der zweiten Spannungsanschlüsse gekoppelt ist als auch mit dem jeweils anderen der ersten und der zweiten Spannungsanschlüsse gekoppelt ist. Überdies betrifft die Erfindung ein Verfahren zum Betreiben eines derartigen Kraftfahrzeugs.The invention relates to a motor vehicle having a circuit arrangement for coupling two first voltage terminals of a first side with two second voltage terminals of a second side to which a higher voltage is applied than to the first voltage terminals, wherein the circuit arrangement comprises an induction machine provided in a star point circuit is, whose star point is coupled to one of the first voltage terminals, and of which a plurality of phase outputs respectively via a bridge comprising two transistors, each with parallel inverse diodes bridge branch of a multi-phase full bridge, which depends on the operating mode of the induction machine, namely as a motor or as a generator , is operable as an inverter or as a rectifier, is both coupled to one of the second voltage terminals and coupled to the other of the first and the second voltage terminals. Moreover, the invention relates to a method for operating such a motor vehicle.
Die Erfindung betrifft die Thematik von Bordnetzen in Kraftfahrzeugen; es geht insbesondere darum, dass unterschiedliche Spannungsverbraucher eine unterschiedliche Bordnetzspannung benötigen, so dass zwei Teilbordnetze vorgesehen sind, eines mit niedrigerer Spannung von zum Beispiel 12 V Bordnetzspannung und eines mit etwas höherer Spannung, zum Beispiel von 24 V oder zum Beispiel auch von 42 V Bordnetzspannung.The invention relates to the subject of on-board networks in motor vehicles; It is particularly important that different voltage consumers require a different electrical system voltage, so that two sub-electrical systems are provided, one with a lower voltage of, for example, 12 V electrical system voltage and one with a slightly higher voltage, for example, 24 V or, for example, 42 V vehicle electrical system voltage ,

Nachteilig an der Anordnung ist, dass die am Energiespeicher C anliegende Spannung UC in etwa die doppelte Spannung der Spannung UBat erreichen kann, die an der Batterie B anliegt. Die Drehfeldmaschine M' arbeitet jedoch dann nicht völlig effizient. Dies gilt insbesondere dann, wenn ihr eine hohe Leistung abgefordert ist, wie dies zum Beispiel beim Rekuperieren oder beim Boosten einer Verbrennungskraftmaschine der Fall ist.A disadvantage of the arrangement is that the voltage present at the energy storage voltage U C C can reach twice the voltage of the voltage U Bat roughly applied to the battery B. However, the induction machine M 'then does not work completely efficient. This is especially true when it is a high performance is required, as is the case for example when recuperating or when boosting an internal combustion engine.
Es ist somit Aufgabe der vorliegenden Erfindung, für eine bessere Ausnutzung der Drehfeldmaschine M' zu sorgen.It is therefore an object of the present invention to ensure better utilization of the induction machine M '.
Die Aufgabe wird durch ein Kraftfahrzeug mit den Merkmalen des Patentanspruchs 1 gelöst und in einem anderen Aspekt durch ein Verfahren mit den Merkmalen gemäß Patentanspruch 5 gelöst.The object is achieved by a motor vehicle having the features of patent claim 1 and in another aspect by a method having the features according to claim 5.
Das erfindungsgemäße Kraftfahrzeug ist somit gekennzeichnet durch eine Steuereinrichtung, welche dazu ausgelegt ist, den Schalter in einer Situation eines Rekuperierens von Bewegungsenergie in einen Energiespeicher oder eines Boostens einer Verbrennungskraftmaschine des Kraftfahrzeugs bei hoher Spannung zwischen den beiden zweiten Spannungsanschlüssen und bei Bedarf einer höheren Leistung der Drehfeldmaschine als derjenigen Leistung, welche bei fester Anbindung des Sternpunkts an den einen der ersten Spannungsanschlüsse und bei einer doppelt so hohen Spannung zwischen den zwei zweiten Spannungsanschlüssen wie der zwischen den zwei ersten Spannungsanschlüssen anliegenden Spannung erreicht werden kann, zu öffnen.The motor vehicle according to the invention is thus characterized by a control device which is adapted to the switch in a situation of Rekuperierens of kinetic energy in an energy storage or a Boostens an internal combustion engine of the motor vehicle at high voltage between the two second voltage terminals and if required a higher power of the induction machine as that power which can be achieved with fixed connection of the neutral point to one of the first voltage terminals and with a voltage twice as high between the two second voltage terminals as the voltage applied between the two first voltage terminals.
Durch den Schalter lässt sich der Sternpunkt von der an der Seite mit niedrigerer Spannung herrschenden Spannung (typischerweise der Batterie oder dem 12 V Energienetz) abkoppeln bzw. entkoppeln. Man erhält somit bei geöffnetem Schalter einen Freiheitsgrad mehr, was die vorherrschenden Spannungen angeht: Das Potential am Sternpunkt kann sich frei einstellen, was man auch als „Floaten” bezeichnet. Die an einem Energiespeicher anliegende Spannung kann bis zum Drei- oder Vierfachen der an der Batterie anliegenden Spannung angehoben werden. Durch die feste Anbindung des Sternpunktes kann die Maschine nicht mit voller Leistung arbeiten. Die Maschine kann nur die Leistung erbringen, die bei doppelter Sternpunktspannung erreicht werden kann, obwohl die Spannung am Energiespeicher den Drei- oder Vierfachen Wert der Batteriespannung hat. Durch ein Öffnen des Sternpunktschalters S1 floatet der Sternpunkt und die Maschine kann mit voller Leistung betrieben werden; dies kann man zum Rekuperieren von Energie oder auch zum Boosten eines Motors nutzen.The switch can be used to decouple or decouple the neutral point from the lower voltage (typically the battery or the 12 V power grid) on the side. Thus, one more degree of freedom is obtained when the switch is open, as far as the prevailing voltages are concerned. The potential at the star point can be set freely, which is also referred to as "floating". The voltage applied to an energy storage voltage can be raised up to three or four times the voltage applied to the battery voltage. Due to the fixed connection of the star point, the machine can not work at full power. The machine can only provide the power that can be achieved with double neutral point voltage, although the voltage at the energy storage has three or four times the value of the battery voltage. By opening the star point switch S1, the neutral point is floating and the machine can be operated at full power; This can be used to recuperate energy or to boost a motor.
Bei einer Alternative der Erfindung ist ein Energiespeicher zwischen die beiden zweiten Spannungsanschlüsse geschaltet, also ein Kondensator oder eine Batterie nach Art des in
Das erfindungsgemäße Kraftfahrzeug ist dazu ausgelegt, den Schalter in einer Situation eines Rekuperierens von Bewegungsenergie in einen Energiespeicher oder eines Boostens einer Verbrennungskraftmaschine des Kraftfahrzeugs zu öffnen. Ist der Schalter als Transistor ausgeführt, kann die Steuereinrichtung unmittelbar diesen Schalter ansteuern. Bei einem mechanischen Schalter steuert die Steuereinrichtung eine Betätigungsvorrichtung wie zum Beispiel ein Relais an.The motor vehicle according to the invention is designed to open the switch in a situation of recuperation of kinetic energy into an energy store or a booster of an internal combustion engine of the motor vehicle. If the switch is designed as a transistor, the control device can directly control this switch. In a mechanical switch, the controller controls an actuator such as a relay.
Bei dem erfindungsgemäßen Verfahren wird in einem erfindungsgemäßen Kraftfahrzeug der Schalter in einer Situation eines Rekuperierens von Bewegungsenergie in einen Energiespeicher hinein oder eines Boostens einer Verbrennungskraftmaschine des Kraftfahrzeugs geöffnet; denn dann kann wiederum der Sternpunkt floaten, auf der Seite höherer Spannung herrscht eine besonders hohe Spannung vor, und die Drehfeldmaschine arbeitet besonders effizient.In the method according to the invention, in a motor vehicle according to the invention, the switch is opened in a situation of recuperation of kinetic energy into an energy store or of a booster of an internal combustion engine of the motor vehicle; because then again the star point can float, on the side of higher voltage prevails a particularly high voltage, and the induction machine works very efficiently.
