Study, development and prototyping of a novel compact hybrid powertrain for small/medium city cars, with multiple energy recovery systems - (english language version)

Funding body: MIUR
Scientific Coordinator: Prof. Laura Tribioli

Project description: Development of an integrated compact hybrid powertrain for city cars, with a turbocharged gasoline engine, an electric machine and a continuously variable transmission. An innovative supercharging system will be designed and implemented: turbine and compressor will be mechanically decoupled, so as to independently optimize their operation. Data retrieved from testing will be used in a model of the entire vehicle to design an efficient supervisory controller for the energy management.

Purpose: Realization of an independent, compact, powertrain, optimized both at component and system levels; Utilization of the distributed drive concept, which enables usage of the same powertrain components for a variety of light passenger cars.
Results: Innovative usage of high performance cars inherited energy recovery systems, such as turbocompounding and KERS, in city cars; Demonstration of performance increase with respect to the original powertrain.
