A hybrid vehicle drive apparatus (1-1) is provided with: an engine (1); a transmission unit including a first planetary gear mechanism (10), a clutch (CL1), and a brake (BK1); and a differential unit including a second planetary gear mechanism (20). By engaging both the clutch (CL1) and the brake (BK1) of the transmission unit, dual-motor EV mode travel driven by a first rotating electrical machine (MG1) and a second rotating electrical machine (MG2) while stopping the engine (1) is enabled. When switching to the dual-motor EV mode travel, first control for implementing negative rotation speed control by the first rotating electrical machine (MG1), second control for engaging one of the clutch (CL1) and the brake (BK1) of the transmission unit after the first control, and third control for engaging both the clutch (CL1) and the brake (BK1) of the transmission unit after the second control are implemented. L'invention porte sur un appareil de propulsion de véhicule hybride (1-1), qui comporte : un moteur thermique (1) ; une unité de transmission comprenant un premier mécanisme de train épicycloïdal (10), un embrayage (CL1) et un frein (BK1) ; et une unité de différentiel comprenant un second mécanisme de train épicycloïdal (20). Sous l'effet de l'accouplement de l'embrayage (CL1) et du frein (BK1) de l'unité de transmission, la marche dans le mode EV à deux moteurs propulsée par une première machine électrique tournante (MG1) et une seconde machine électrique tournante (MG2), en même temps que le moteur thermique (1) est arrêté, est rendue possible. Lors de la commutation sur la marche dans le mode EV à deux moteurs, il se produit une première commande pour mettre en action une commande de vitesse de rotation négative par la première machine électrique tournante (MG1), une deuxième commande pour serrer l'un parmi l'embrayage (CL1) et le frein (BK1) de l'unité de transmission, après la première commande, et une troisième commande pour serrer à la fois l'embrayage (CL1) et le frein (BK1) de l'unité de transmission après la deuxième commande.
