Description
Die Erfindung betrifft ein Kraftfahrzeug mit einem Verbrennungsmotor und wenigstens einem Elektromotor, wobei der Verbrennungsmotor mit einem Getriebe über eine Kupplung verbunden ist und der Elektromotor kraftschlüssig mit dem Getriebe verbunden ist.The invention relates to a motor vehicle with an internal combustion engine and at least one electric motor, wherein the internal combustion engine is connected to a transmission via a coupling and the electric motor is non-positively connected to the transmission.
Kraftfahrzeug mit Hybridantrieben, d. h. gleichzeitig Verbrennungsmotor und Elektromotor, sind grundsätzlich bekannt. Dabei wird der Elektromotor oft über eine Kupplung an einer Stelle des Antriebsstranges, beispielsweise dem Getriebe, angebunden.Motor vehicle with hybrid drives, d. H. at the same time combustion engine and electric motor, are basically known. In this case, the electric motor is often connected via a coupling at a point of the drive train, such as the transmission.
Dabei besteht das Problem, das Kraftfahrzeug so auszugestalten, dass der Fahrer einerseits ein Hybridfahrzeug fährt und andererseits die gewohnte Bediensituation vorfindet.There is the problem, the motor vehicle in such a way that the driver on the one hand drives a hybrid vehicle and on the other hand finds the usual operating situation.
Zur Lösung dieses Problems wird ein Kraftfahrzeug mit den Merkmalen von Anspruch 1 vorgeschlagen. Weiterführende Ausgestaltungen ergeben sich aus den Unteransprüchen.To solve this problem, a motor vehicle with the features of claim 1 is proposed. Further developments emerge from the subclaims.
Als Kern der Erfindung wird angesehen, dass die den Verbrennungsmotor und das Getriebe verbindende Kupplung über einen Kupplungsaktuator betätigt wird und weiterhin der Elektromotor kraftschlüssig mit dem Getriebe verbunden ist. Durch das Vorsehen des Kupplungsaktuators kann nämlich der Verbrennungsmotor zu- und weggeschaltet werden, ohne dass es der Fahrer bemerkt. So kann die Steuerungsstrategie mit der Fahr- und Kupplungsstrategie des Fahrers überlagert werden, ohne dass der Fahrer seine Fahrstrategie ändern müsste oder etwas von der Überlagerung bemerkt.As the core of the invention is considered that the connecting the engine and the transmission clutch is actuated via a clutch actuator and further the electric motor is non-positively connected to the transmission. Namely, by providing the clutch actuator, the engine can be switched on and off without the driver noticing. Thus, the control strategy can be overlaid with the driving and clutch strategy of the driver without the driver having to change his driving strategy or noticing something of the overlay.
Dabei ist der Kupplungsaktuator bevorzugt so aufgebaut, dass er eine Antriebseinheit und ein das von der Antriebseinheit abgegebene drehmomentübersetzendes Getriebe aufweist. Damit soll zumindest klargestellt werden, dass es sich bei dem Kupplungsaktuator um einen Aktuator handelt, wie er beispielsweise in einem Kraftfahrzeug mit sogenanntem automatisierten Schaltgetriebe vorzufinden ist und nicht um eine Betätigungseinheit eines Handschaltgetriebe-Kraftfahrzeugs. Durch die Verwendung des Kupplungsaktuators wird es nämlich möglich, den Verbrennungsmotor vom Antriebsstrang abzukoppeln, ohne dass der Fahrer ein Kupplungspedal betätigen müsste.In this case, the clutch actuator is preferably constructed such that it has a drive unit and a torque-transmitting transmission that is output by the drive unit. This should at least make it clear that it is the clutch actuator is an actuator, as it is found for example in a motor vehicle with so-called automated manual transmission and not an operating unit of a manual transmission motor vehicle. Namely, by using the clutch actuator, it becomes possible to decouple the engine from the driveline without the driver having to operate a clutch pedal.
Vorteilhafterweise und alternativ zur beschriebenen Ausgestaltung des Kupplungsaktuators mit Antriebseinheit und Getriebe kann dieser auch eine Pumpeinheit und ein Ventil aufweisen. Der Kupplungsaktuator kann also auch als hydraulischer Kupplungsaktuator ausgestaltet sein.Advantageously, and as an alternative to the described embodiment of the clutch actuator with drive unit and transmission, this can also have a pump unit and a valve. The clutch actuator can therefore also be designed as a hydraulic clutch actuator.
Dann ist der Kupplungsaktuator bevorzugt an eine hydraulische Wegstrecke einer Kupplungsbetätigung angebunden. Durch das Vorsehen des Ventils ist es möglich, ein länger anhaltendes Öffnen der Kupplung zu ermöglichen, ohne dass dies Energieaufwand verursacht.Then the clutch actuator is preferably connected to a hydraulic path of a clutch actuation. By providing the valve, it is possible to allow a longer-lasting opening of the clutch, without causing energy expenditure.
Vorteilhafterweise kann an die hydraulische Wegstrecke weiterhin ein Kupplungspedal angeschlossen sein. Dementsprechend kann die Kupplung vom Fahrer hydraulisch betätigt werden, beim Wegschalten der Fahrerbetätigung muss der Nehmerzylinder so umgeleitet werden, dass der Fahrer ein gewohntes Betätigungsverhalten der Kupplung bzw. des Kupplungspedals vorfindet, obwohl die Kupplung mittels des Kupplungsaktuators geöffnet ist.Advantageously, a clutch pedal may be connected to the hydraulic path. Accordingly, the clutch can be actuated hydraulically by the driver, when switching off the driver operation, the slave cylinder must be redirected so that the driver finds a familiar operating behavior of the clutch or the clutch pedal, although the clutch is opened by means of the clutch actuator.
Vorteilhafterweise ist das Getriebe als Handschaltgetriebe ausgebildet.Advantageously, the transmission is designed as a manual transmission.
Weiterhin bevorzugt kann das Kraftfahrzeug ein Kupplungspedal mit einem Positionssensor aufweisen. Es handelt sich also um eine sogenannte Clutch-By-Wire-Kupplung. Das Signal des Positionssensors kann dabei sowohl auf einen elektromechanischen Kupplungsaktuator wie auch auf einen hydraulischen Kupplungsaktuator gegeben werden.Further preferably, the motor vehicle may have a clutch pedal with a position sensor. It is therefore a so-called clutch-by-wire coupling. The signal of the position sensor can be given both to an electromechanical clutch actuator as well as to a hydraulic clutch actuator.
Daneben betrifft die Erfindung ein Verfahren zum Betrieb eines Kraftfahrzeugs, wobei das Kraftfahrzeug einen Verbrennungsmotor mit wenigstens einem Elektromotor umfasst, wobei der Verbrennungsmotor mit einem Getriebe über eine Kupplung verbunden ist und der Elektromotor kraftschlüssig mit dem Getriebe verbunden ist. Das Verfahren zeichnet sich dadurch aus, dass
- – die Kupplung in einem ersten Betriebszustand geschlossen ist und der Elektromotor motorisch oder rekuperativ betrieben wird, und
- – in einem zweiten Betriebszustand die Kupplung geöffnet ist und der Elektromotor motorisch betrieben wird.
- - The clutch is closed in a first operating state and the electric motor is operated by motor or recuperative, and
- - In a second operating state, the clutch is open and the electric motor is operated by a motor.
Der Elektromotor kann bei Anbindung des Verbrennungsmotors an das Getriebe entweder zur Leistungssteigerung verwendet werden oder aufgeladen werden. Daneben weist das Kraftfahrzeug einen reinen Elektrobetrieb auf.The electric motor can either be used to boost performance or be charged when connecting the engine to the transmission. In addition, the motor vehicle has a pure electric operation.
Vorteilhafterweise kann ein Schaltelement im Kraftfahrzeug vorgesehen sein, mit dem Wechsel vom ersten in den zweiten Betriebszustand durch den Fahrer vornehmbar ist. Das Schaltelement kann beispielsweise am Wählhebel ausgebildet sein, es kann sich aber auch um einen Betätigungsknopf irgendwo im Kraftfahrzeug handeln.Advantageously, a switching element may be provided in the motor vehicle, with the change from the first to the second operating state by the driver vornehmbar. The switching element may for example be formed on the selector lever, but it may also be an actuating button anywhere in the vehicle.
Besonders bevorzugt kann ein Kupplungsaktuator zum Öffnen der Kupplung verwendet werden. Dieser kann wie weiter oben beim Kraftfahrzeug beschrieben ausgebildet sein.Particularly preferably, a clutch actuator can be used to open the clutch. This can be designed as described above in the motor vehicle.
Vorteilhafterweise kann ein Kupplungsaktuator verwendet werden, der eine Pumpeneinheit und ein Ventil aufweist und der in eine hydraulische Wegstrecke der Kupplungsbetätigung eingebunden ist. Diese Ausgestaltung ist weiter oben bereits ausführlicher beschrieben.Advantageously, a clutch actuator can be used, which has a pump unit and a valve and which is integrated into a hydraulic path of the clutch actuation. This embodiment has already been described in more detail above.
