摘要

A real-time control system for the powertrain management of a Range ExtendedrnElectric Vehicle (RE-EV) is presented in this paper. Aspects such us the powertrainrnsupervisory control and the energy/power management are taken into account in the overallrnpowertrain control strategy with the objective of increase the vehicle range when reducing atrnthe same time the fuel consumption of the range extender unit. The supervisory control isrncarried out by a finite state machine according with the powertrain state variables and thernvehicle commands requested by the driver. A feed-forward near-optimal switching on/offrnprimary strategy for the range extender control is derived from a Look-Up-Table (LUT) basedrnon the driving cycle pattern. The LUT is off-line filled in by solving an optimization problemrnfor different driving cycle patterns. A Dynamic Programming (DP) based algorithmrnconsidering a constrained powertrain backward model is used in order to search for thernoptimal range extender on/off strategy that minimizes the fuel consumption and assures thernarrival to the final destination. Functional and operational constraints related with the batteryrnstate of charge (SOC) and the range extender maximum switching frequency are alsornconsidered in the optimization problem formulation. The primary energy strategy obtained byrninterpolation from the LUT is on-line updated by a feedback controller according with the realrnSOC of the battery. For the in-vehicle implementation, rapid prototyping tools andrnmethodologies are used. The supervisory control architecture, the energy/power managementrnstrategy, the rapid prototyping real time system and the results obtained from testing in arnrange extended electric vehicle are presented and discussed in this paper.
