The device has a planetary gearset (1) e.g. Ravigneaux gearset, engaging with a heat engine (2), a motor/generator (3), and an electric motor (4). The gearset has an outer crown (12) driven in rotation by the electric motor, and a planet carrier (13) driving an output shaft (16). The gearset has two sun gears (8, 10) driven by the engine and the motor/generator, respectively. A torque converter is arranged between the engine and the gearset.
