Abstract

A vehicle's internal combustion engine (1) links to a first element (9) in a summing transmission (ST) (3). An electric motor (2) links to a second element (10) in the ST. A gear feed shaft links to a third element (11) in the ST. A clutch (14) interlinks two ST elements but keeps them detachable. When the clutch is engaged, the ST rotates in a blocking operation.

Description

  • Die vorliegende Erfindung bezieht sich auf ein Verfahren zum Gangauslegen für ein Fahrzeug, umfassend ein automatisiertes Getriebe und ein elektrodynamisches Antriebssystem, gemäß dem Oberbegriff des Patentanspruchs 1. The present invention relates to a method of gear shifting for a vehicle comprising an automated transmission and an electro-dynamic drive system, according to the preamble of claim 1.
  • Aus dem Stand der Technik sind elektrodynamische Antriebssysteme bekannt. From the state of the art electro-dynamic drive systems are known. Beispielsweise beschreibt die For example describes the DE 199 34 696 A1 DE 199 34 696 A1 der Anmelderin ein elektrodynamisches Antriebssystem für ein Fahrzeug, welches zwischen einer Antriebsmaschine und einem Schaltgetriebe ein als Summierungsgetriebe dienendes Planetengetriebe, umfassend die drei Elemente Sonnenrad, Hohlrad und Planetenträger aufweist. the Applicant an electrodynamic drive system for a vehicle having between a drive engine and a gearbox serving as a summation planetary gear, which comprises the three elements sun gear, internal gear and planet carrier. Hierbei ist ein erstes Element des Planetengetriebes mit dem Schaltgetriebe, ein zweites Element mit der Antriebsmaschine und ein drittes Element mit wenigstens einem Elektromotor verbunden, so dass ein verschleißfreies Anfahrelement für das Fahrzeug gebildet wird. In this case, a first member of the planetary transmission with the manual transmission, a second element with the engine and a third element with at least one electric motor is connected so that a wear-free starting element is formed for the vehicle.
  • Die The DE 101 52 471 A1 DE 101 52 471 A1 der Anmelderin beschreibt ein Verfahren zum Anlassen eines Verbrennungsmotors eines mit einem elektrodynamischen Antriebssystem ausgerüsteten Fahrzeugs, das einen Elektromotor und ein Planetengetriebe zwischen dem Verbrennungsmotor und einem Schaltgetriebe mit Eingangswelle umfasst. of the Applicant describes a method for starting an engine of a vehicle equipped with an electrodynamic drive system vehicle comprising an electric motor and a planetary gear between the engine and a gearbox having input shaft. Bei dem bekannten elektrodynamischen Antriebssystem wird zunächst der Elektromotor auf eine Drehzahl beschleunigt, die grundsätzlich ausreichend ist, um den Verbrennungsmotor zu starten; In the known electro-dynamic drive system, the electric motor is first accelerated to a speed which is in principle sufficient to start the engine; danach erfolgt eine geregelte Schließung einer die Drehung der Eingangswelle des Schaltgetriebes abbremsenden Bremse gegen ein feststehendes Gehäuseteil, wodurch ein Moment als Summe aus Elektromotormoment und Rotationsmoment der rotierenden Bauteile auf den Verbrennungsmotor wirkt. thereafter, a controlled closure of a rotation of the input shaft of the gearbox decelerating brake against a stationary housing part, whereby a moment acts as the sum of electric motor torque and rotation moment of the rotating components on the engine takes place. Hierbei ist eine Kupp lung vorgesehen, welche das Sonnenrad und den Steg des Planetengetriebes lösbar miteinander verbindet, um das Planetengetriebe zu verblocken. Here, a Kupp system is provided, which connects the sun gear and the carrier of the planetary gear detachably to one another so as to interlock the planetary gear.
  • Bei automatisierten Getrieben wird zum Gangauslegen ein Drehmoment-Nulldurchgang benötigt. In automatic transmissions for gear disengagement, a torque zero crossing is needed. Bei negativem Motormoment, dh beim Schubbetrieb des Verbrennungsmotors, kann zu diesem Zweck dem Verbrennungsmotor ein kurzer „Gasstoß" (Zwischengas) vorgegeben werden, um den erforderlichen Drehmoment-Nulldurchgang zu realisieren. Diese Vorgehensweise ist unbedingt erforderlich, wenn keine Abkopplung des Getriebes vom Verbrennungsmotor möglich ist. With a negative motor torque, ie at the push operation of the engine, a short "gas blow" (declutching) can be specified for this purpose the internal combustion engine in order to realize the required torque zero crossing. This procedure is essential if there is no decoupling of the transmission from the engine possible is.
  • Der kurze Gasstoß führt, falls sich der Gang nicht sofort auslegen lässt, in nachteiliger Weise zu einer ungewollten Beschleunigung des Fahrzeugs. The short burst of gas leads if the gear can not be interpreted immediately, adversely to an unwanted acceleration of the vehicle. Dies kann wiederum in einer sicherheitskritischen Situation resultieren, insbesondere dann, wenn der Schubbetrieb dem Fahrerwunsch entspricht. This in turn may result in a safety-critical situation, especially when the pushing operation corresponds to the driver's request.
  • Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Gangauslegen für ein Fahrzeug mit einem automatisierten Getriebe und einem elektrodynamischen Antriebssystem anzugeben, welches einen Elektromotor bzw. eine elektrische Maschine und ein Summierungsgetriebe aufweist, wobei eine Kupplung vorgesehen ist, welche zwei Elemente des Summierungsgetriebes lösbar miteinander verbindet, wodurch im geschlossenen Zustand der Kupplung das Summierungsgetriebe im Blockbetrieb umläuft, durch dessen Durchführung die Gefahr einer ungewollten Beschleunigung im Schubbetrieb des Verbrennungsmotors weitgehend vermieden wird. The present invention has for its object to provide a method of gear shifting for a vehicle having an automated transmission and an electrodynamic drive system comprising an electric motor or an electric machine and a summing transmission, wherein a clutch is provided which comprises two elements of the summing gear releasably connecting together, whereby the summing circulates in the closed state of the clutch operation in the block, through the implementation of a risk of unwanted acceleration is largely avoided in the overrun mode of the internal combustion engine.
