The optimization of consumption is one of the main challenges of today’s automotive world. The increasing imposed restrictions require seeking means to reduce consumption. The proposed work aims to reduce the consumption of an existing vehicle through the exploitation of currently available technologies. The vehicle is characterized by a P2 parallel type full-hybrid electric architecture. In this context three possible approaches are used. The first involves the study and comparison between the automatic transmission present in the standard vehicle and a Dual Clutch Transmission (DCT). This comparison wanted to evaluate the efficiency performance among different control logics implemented in the DCT and the automatic transmission.
