Abstract
Through-the-road (TTR) hybrid designs using control strategies such as an equivalent consumption minimization strategy (ECMS) or adaptive ECMS are implemented at the supplemental torque delivering electrically-powered drive axle (or axles) in a manner that follows operational parameters or computationally estimates states of the primary drivetrain and/or fuel-fed engine, but does not itself participate in control of the fuel-fed engine or primary drivetrain. Crowdsourced distributions of adaptations and/or selections of BSFC type data allow ECMS implementations (or other similar control strategies) employ efficiency curves for a particular paired-with fuel-fed engine and/or operating conditions and to improve overall efficiencies of the TTR hybrid configuration. In some cases, signatures are used to identify appropriate BSFC type data for crowdsourced dissemination.
