L'invention concerne un système d'entraînement (1) destiné à un véhicule automobile hybride (31), comprenant un arbre de moteur (4) pouvant être accouplé rotativement ou accouplé à un arbre de sortie (2) d'un moteur à combustion interne (3), un premier moteur électrique (6) présentant un premier arbre de rotor (5) et fonctionnant comme générateur dans un état de fonctionnement principal, un second moteur électrique (8) présentant un second arbre de rotor (7) radialement décalé par rapport au premier arbre de rotor (5) et fonctionnant comme moteur d'entraînement dans l'état de fonctionnement principal, une pièce d'entraînement (10) reliée rotativement au second arbre de rotor (7) et pouvant être reliée rotativement à au moins une roue (9a, 9b) du véhicule automobile (31) ainsi qu'une unité de boîte de vitesses (11) embrayable insérée entre l'arbre de moteur (4), les deux arbres de rotor (5, 7) et la pièce d'entraînement (10) de manière à agir, un dispositif d'embrayage (12) commandant une position d'embrayage de l'unité de boîte de vitesses (11) étant inséré de manière à agir entre l'arbre de moteur (4), une première roue dentée (13) pouvant être accouplée rotativement de façon permanente au premier arbre de rotor (5) et une seconde roue dentée (15) accouplée rotativement de façon permanente au second arbre de rotor (7) par l'intermédiaire d'un étage de transmission planétaire (14) supplémentaire de telle sorte que le dispositif d'embrayage (12) relie rotativement l'arbre de moteur (4) au premier arbre de rotor (5) dans une première position d'embrayage alors que le second arbre de rotor (7) est découplé rotativement de l'arbre de moteur (4), que l'arbre de moteur (4) relie rotativement aussi bien le premier arbre de rotor (5) que le second arbre de rotor (7) dans une seconde position d'embrayage et relie rotativement les deux arbres de rotor (5, 7) l'un à l'autre dans une troisième position d'embrayage, alors que l'arbre de moteur (4) est découplé rotativement des deux arbres de rotor (5, 7). L'invention concerne en outre un véhicule automobile (31) comportant un tel système d'entraînement (1).
