Abstract
Description
Die Erfindung betrifft eine Hybridantriebsstrangvorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a hybrid drive train device according to the preamble of claim 1.
Aus der
Der Erfindung liegt insbesondere die Aufgabe zugrunde, eine besonders vorteilhafte Hybridantriebsstrangvorrichtung bereitzustellen, die bei einem Zustart des Verbrennungsmotors eine besonders vorteilhaft kurze Schaltzeit aufweist und insbesondere vorteilhaft Schwingungsanregungen während des Schaltvorgangs und des Zustarts des Verbrennungsmotors dämpft. Sie wird gemäß der Erfindung durch die Merkmale des Anspruchs 1 gelöst. Weitere Ausgestaltungen ergeben sich aus den Unteransprüchen.The invention is in particular the object of providing a particularly advantageous hybrid powertrain device, which has a particularly advantageous short switching time at a Zustart the engine and particularly advantageous dampen vibration excitations during the shift operation and the start of the engine. It is achieved according to the invention by the features of claim 1. Further embodiments emerge from the subclaims.
Die Erfindung geht aus von einer Hybridantriebsstrangvorrichtung mit einer Getriebevorrichtung, die zur Bereitstellung verschiedener Getriebegänge zumindest zwei Kupplungseinheiten aufweist, und mit einer Steuer- und/oder Regeleinheit, die zumindest dazu vorgesehen ist, während eines Getriebegangwechsels ein Kupplungsmoment sukzessive von der abschaltenden Kupplungseinheit an die zuschaltende Kupplungseinheit zu übergeben und zeitgleich einen Zustart eines Verbrennungsmotors durchzuführen.The invention relates to a hybrid powertrain device with a transmission device which has at least two clutch units for providing different gears, and with a control and / or control unit, which is at least provided during a gear change a clutch torque successively from the disconnecting clutch unit to the zuschaltende Passing coupling unit and at the same time carry out a Zustart an internal combustion engine.
Es wird vorgeschlagen, dass die Steuer- und/oder Regeleinheit für einen Getriebegangwechsel dazu vorgesehen ist, bei dem Zustart des Verbrennungsmotors das Kupplungsmoment an der abschaltenden Kupplungseinheit zumindest zeitweise zumindest im Wesentlichen konstant zu halten. Dadurch kann der Verbrennungsmotor vorteilhaft einfach zugestartet werden und ein schneller Getriebegangwechsel durchgeführt werden. Unter einer „Getriebevorrichtung” soll insbesondere ein Automatikgetriebe verstanden werden, das durch Öffnen und Schließen verschiedener Kupplungseinheiten verschiedene Getriebegänge bereitstellt, wobei die Getriebevorrichtung vorzugsweise aus mehreren zusammengeschalteten Planetenradsätzen besteht. Unter einer ”Steuer- und/oder Regeleinheit” soll insbesondere eine Einheit mit zumindest einem Steuergerät verstanden werden. Unter einem ”Steuergerät” soll insbesondere eine Einheit mit einer Prozessoreinheit und mit einer Speichereinheit sowie mit einem in der Speichereinheit gespeicherten Betriebsprogramm verstanden werden. Grundsätzlich kann die Steuer- und/oder Regeleinheit mehrere untereinander verbundene Steuergeräte aufweisen, die vorzugsweise dazu vorgesehen sind, über ein Bus-System, wie insbesondere ein CAN-Bus-System, miteinander zu kommunizieren. Unter „vorgesehen” soll insbesondere speziell programmiert, ausgelegt und/oder ausgestattet verstanden werden. Unter „zumindest im Wesentlichen” soll in diesem Zusammenhang insbesondere verstanden werden, dass eine Abweichung von einem konstanten Kupplungsmoment insbesondere weniger als 25%, vorzugsweise weniger als 10% und besonders bevorzugt weniger als 5% des konstanten Kupplungsmoments beträgt. Unter einem „Getriebegangwechsel” soll insbesondere ein Wechsel von einem Getriebegang in einen anderen Getriebegang einer Getriebevorrichtung verstanden werden. Unter einem „Kupplungsmoment” soll dabei insbesondere ein Moment verstanden werden, das von der Kupplungseinheit übertragen werden kann. Unter ein „Kupplungsmoment übergeben” soll insbesondere verstanden werden, dass die Steuer- und/oder Regeleinheit eine abschaltende Kupplungseinheit über einen Aktuator so ansteuert, dass ihr übertragbares Kupplungsmoment immer kleiner wird, während sie eine zuschaltende Kupplungseinheit über einen weiteren Aktuator so ansteuert, dass ihr übertragbares Kupplungsmoment immer größer wird, wodurch das übertragene Moment sukzessive von der abschaltenden Kupplungseinheit an die zuschaltende Kupplungseinheit übertragen wird.It is proposed that the control and / or regulating unit for a transmission gear change is provided to keep the clutch torque at the disconnecting clutch unit at least temporarily at least substantially constant during the start of the internal combustion engine. As a result, the internal combustion engine can advantageously be started up easily and a faster transmission gear change can be carried out. A "transmission device" is to be understood in particular to mean an automatic transmission which provides different transmission gears by opening and closing different clutch units, wherein the transmission device preferably consists of several interconnected planetary gear sets. A "control and / or regulating unit" is to be understood in particular as a unit having at least one control unit. A "control unit" is to be understood in particular as meaning a unit having a processor unit and a memory unit as well as an operating program stored in the memory unit. In principle, the control and / or regulating unit can have a plurality of interconnected control units, which are preferably provided to communicate with one another via a bus system, in particular a CAN bus system. By "provided" is intended to be understood in particular specially programmed, designed and / or equipped. By "at least substantially" should be understood in this context in particular that a deviation from a constant clutch torque is in particular less than 25%, preferably less than 10% and particularly preferably less than 5% of the constant clutch torque. A "gear change" is to be understood in particular a change from one gear to another gear of a transmission device. A "clutch torque" should be understood to mean, in particular, a moment that can be transmitted by the clutch unit. A "clutch torque" is to be understood in particular as meaning that the control and / or regulating unit controls a disconnecting clutch unit via an actuator in such a way that its transmissible clutch torque becomes smaller and smaller, while it activates a clutch unit to be engaged via a further actuator in such a way that it transmissible clutch torque is always greater, whereby the transmitted torque is successively transmitted from the disconnecting coupling unit to the engaging clutch unit.
Weiter wird vorgeschlagen, dass die Steuer- und/oder Regeleinheit dazu vorgesehen ist, das Kupplungsmoment der abschaltenden Kupplungseinheit an ein von einem Fahrer angefordertes Moment anzupassen. Dadurch kann insbesondere während des Schaltvorgangs vorteilhaft auf einen Fahrerwunsch reagiert werden. Unter das „Kupplungsmoment anpassen” soll insbesondere verstanden werden, dass die Steuer- und/oder Regeleinheit in Abhängigkeit eines Fahrerwunsches die abschaltende Kupplungseinheit so ansteuert, dass ihr übertragbares Kupplungsmoment größer oder kleiner wird.It is also proposed that the control and / or regulating unit is provided to adapt the clutch torque of the disconnecting clutch unit to a torque requested by a driver. As a result, it is possible to respond advantageously to a driver request, in particular during the switching process. The "adapting the clutch torque" is to be understood in particular as meaning that the control and / or regulating unit controls the disconnecting clutch unit as a function of a driver's request in such a way that its transmissible clutch torque becomes greater or smaller.
