Hardware In the Loop Simulation of a Diesel Parallel Mild-Hybrid Electric Vehicle

Hybrid vehicles present a real potential to reduce CO2 emission and energy dependency. The simulation of these vehicles is well adapted to highlight the first order influent parameters. However, more realistic components and HEVs performance versus cost could be identified and improved by testing using the HIL concept. This paper deals with the test and validation of a parallel mild-hybrid vehicle with a first HIL configuration presenting a low additional cost. Measured fuel consumption reduction values for the HEV, compared to a given reference conventional vehicle, are presented and discussed.
