Powertrain testbed

Control room

The infrastructure is dedicated to testing vehicles (mass up to 3500 kg, wheelbase up to 4100 mm, track up to 2000 mm) and conventional, hybrid and electric powertrains (with power provided by thermal power units up to 375 kW and power provided by electric motors up to 250 kW) in a temperature-controlled laboratory environment, to allow full power tests in powertrain mode and at 70% of the maximum power (thermal + electric) in vehicle mode (with possibility of managing peaks of 100% for limited time). The infrastructure enables testing cycles required by international regulations as well as non-standard driving cycles, such as those obtained by road testing to validate control strategies of the energy management system by measuring consumption, efficiencies and emissions. In fact, the infrastructure is equipped with measurement systems of fuel and pollutants, mechanical power to the wheels and electric power. The infrastructure is also equipped with a driving simulator interface system and external simulation models to validate assisted and autonomous driving technologies as well as their impact on energy consumption and emissions.
