L'un des éléments d'entraînement (202, 302) est fixé à un moteur à combustion interne du véhicule (100) tandis que l'autre élément d'entraînement (206, 304) est attaché au moteur électrique (210) du véhicule (100). L'élément entraîné (212, 306), quant à lui, est fixé sur la roue d'entraînement (106) du véhicule (100) via une boîte de vitesse (220). Un élément de transmission commun (214, 308) est utilisé pour faciliter le transfert d'énergie depuis les éléments d'entraînement (202, 302, 206, 304) vers l'élément entraîné (212, 306).
