Implementation of a Fuzzy Control System for a Parallel Hybrid Vehicle Powertrain on CompactRio

In the present paper it is discussed the design and the implementation of a fuzzy control system for efficient energy management of a parallel hybrid vehicle powertrain. A simple strategy, based on two control signals is adopted to realize the split of the driver request between the internal combustion engine and the electric motor during the acceleration phases. Similarly, during the deceleration phases a dedicated set of fuzzy rules is used to control the regenerative braking. The proposed strategy has been implemented in LabView in order to easily program a compact reconfigurable input/output hardware device produced by National Instruments. The powertrain controller has been developed to be installed on a high performance sport parallel hybrid electric prototype under construction in the Polo per La Mobilità Sostenibile Laboratories.
