Title
(DE) VERFAHREN ZUM START EINES VERBRENNUNGSMOTORS EINES HYBRIDFAHRZEUGES

Abstract
(DE)
Die Erfindung betrifft ein Verfahren zum Start eines Verbrennungsmotors eines Hybridfahrzeuges, bei welchem ein abtriebsseitig angeordneter erster Elektromotor (4), ein verbrennungsmotorseitig angeordneter zweiter Elektromotor (6) und der Verbrennungsmotor (2) über eine Hybridtrennkupplung (5) mit einem Abtrieb (3) des Hybridfahrzeuges verbunden oder von diesem getrennt werden, wobei ein durch den Verbrennungsmotor (2) und/oder den ersten Elektromotor (4) und/oder den zweiten Elektromotor (6) ausgegebenes Drehmoment an Antriebsräder (3) des Hybridfahrzeuges weitergeleitet wird. Bei einem Verfahren, bei welchem ein zuverlässiger Start des Verbrennungsmotors jederzeit möglich ist, beschleunigt während einer elektrischen Fahrt des Hybridfahrzeuges mit dem ersten Elektromotor (4) die schlupfende Hybridtrennkupplung (5) den unbefeuerten Verbrennungsmotor (2) bis zur ersten Zündung des Verbrennungsmotors (2).
(EN)
The invention relates to a method for starting an internal combustion engine of a hybrid vehicle. In said hybrid vehicle, a first electric motor (4) arranged on the output side, a second electric motor (6) arranged on the internal combustion engine side, and the internal combustion engine (2) are connected to or disconnected from an output (3) of the hybrid vehicle by means of a hybrid disconnect clutch (5), and a torque which is output by the internal combustion engine (2) and/or the first electric motor (4) and/or the second electric motor (6) is transmitted to drive wheels (3) of the hybrid vehicle. In a method in the case of which a reliable start of the internal combustion engine is possible at all times, during electric travel of the hybrid vehicle by means of the first electric motor (4) the slipping hybrid disconnect clutch (5) accelerates the non-operating internal combustion engine (2) until the first ignition of the internal combustion engine (2).
(FR)
L'invention concerne un procédé de démarrage d'un moteur à combustion interne d'un véhicule hybride, selon lequel un premier moteur électrique (4) monté côté sortie, un second moteur électrique (6) monté côté moteur électrique (6) et le moteur à combustion interne (2) sont reliés par l'intermédiaire d'un embrayage de coupure hybride (5) à une sortie (3) du véhicule hybride ou en sont séparés, un couple fourni par le moteur à combustion interne (2) et/ou par le premier moteur électrique (4) et/ou par le second moteur électrique (6) étant transmis au roues motrices (3) du véhicule hybride. Selon un procédé dans lequel un démarrage fiable du moteur à combustion interne est possible à tout moment, pendant un parcours en mode électrique du véhicule hybride, l'embrayage de coupure hybride (5) à l'état de patinage accélère le moteur à combustion interne (2) non allumé jusqu'à un premier allumage dudit moteur à combustion interne (2).
