Under the dual-carbon goals, the development of the new energy vehicle industry has been rapidly advancing. The powertrain serves as the core of new energy vehicles, and whether automated control technologies in this field can be innovatively applied directly impacts the enhancement of vehicle performance, energy efficiency, and driving safety. This paper reviews the application value of such technologies within the powertrain, analyzes their innovative forms in areas like integrated intelligence, motor drive, and battery management, and evaluates the practical effects of technology implementation through benchmark cases of pure electric vehicles. The study finds that automated control technologies have penetrated all core modules of the powertrain, not only improving system operational efficiency but also significantly elevating the overall intelligence level of the vehicles.
