Design and evaluation of a predictive powertrain control system for a plug-in hybrid electric vehicle to improve the fuel economy and the emissions

摘要: In this article, a power management scheme for plug-in power-split hybrid electric vehicle is designed on the basis of model predictive control concept charge depletion plus sustenance strategy and blended-mode strategy. The commands are applied to powertrain components through appropriate low-level controllers: standard proportional–integral controllers machines, sliding-mode engine torque control. Minimization emissions key factor designing engine’s controller. Applying validated high-fidelity vehicle, developed in MapleSim environment with chemistry-based Lithium-ion battery model, results considerable improvements fuel economy performance.
