Gasoline-HEV Equivalent Consumption and Pollutant Minimization Strategy

This article proposes a strategy which works on the fuel consumption / pollutant compromise with a gasoline Hybrid Electric Vehicle (HEV). First, a pollutant-constrained optimal energy management is derived from the Pontryagin's Minimum Principle (PMP). Using only one parameter and considering standardized pollutant emissions, this approach is validated on a high-fidelity HEV model. Then, an online approach called the Equivalent Consumption and Pollutant Minimization Strategy (ECPMS), is explained and applied on a Hybrid Hardware In the Loop (Hy-HIL) test bench. This strategy reproduces the fuel consumption / pollutant trade-off with one tuning parameter and reduces pollutant emissions for a light fuel consumption penalty.
