Electrical architecture of a hybrid vehicle hybrid vehicle and control method

摘要

An electrical structure of a hybrid vehicle including a combustion engine 19, an electric traction machine 7, and a hybrid transmission 17 is provided, The combustion engine 19 drives an alternating current generator 21 for recharging a low voltage internal battery 22 connected to a starter 24 of a combustion engine and an automobile built-in network 24, The electric traction machine 7 is powered by a high voltage traction battery 18, The hybrid transmission (17) comprises at least a first position in which the combustion engine is separated from a drive train connecting the electric traction machine (7) to wheels, a first position in which the combustion engine The combustion engine 19 and the electric traction machine 7 are connected so that the torques of the combustion engine 19 and the electric traction machine 7 are directed to the wheels at a second position where the engine 19 drives the wheels, (5) capable of occupying a third position, In the electric mode, the combustion engine (19) and the alternating current generator (21) constitute an electric generator set capable of supplying an energy required amount of the electric traction machine (7).
