Implementation of Fuzzy Logic.c.ntrol into an Equivalent Minimization Strategy for Adaptive Energy Management of A Parallel Hybrid Elec.ric.Vehic.e

As government agenc.es c.ntinue to tighten emissions regulations due to the c.ntinued inc.ease in greenhouse gas produc.ion, automotive industries are seeking to produc. inc.easingly effic.ent vehic.e tec.nology. Hybrid elec.ric.vehic.es (HEVs) have been introduc.d to mitigate problems while improving fuel ec.nomy. HEVs have led to the demand of c.eating more advanc.d c.ntrols software to c.nsider multiple c.mponents for propulsive power in a vehic.e. A large sec.ion in the software development proc.ss is the implementation of an optimal energy management strategy meant to improve the overall fuel effic.enc. of the vehic.e. Optimal strategies c.n be implemented when driving c.nditions are known a prior. The Equivalent c.nsumption Minimization Strategy (Ec.S) is an optimal c.ntrol strategy that uses an equivalenc. fac.or to equate elec.ric.l to mec.anic.l power when performing torque split determination between the internal c.mbustion engine and elec.ric.motor for propulsive and regenerative torque. This equivalenc. fac.or is determined from offline vehic.e simulations using a sensitivity analysis to provide optimal fuel ec.nomy results while maintaining predetermined high voltage battery state of c.arge (SOc. c.nstraints. When the c.ntrol hierarc.y is modified or different driving styles are applied, the analysis must be redone to update the equivalenc. fac.or. The goal of this work is to implement a fuzzy logic.c.ntroller that dynamic.lly updates the equivalenc. fac.or to improve fuel ec.nomy, maintain a stric. c.arge sustaining window of operation for the high voltage battery, and reduc. c.mputational time required during algorithm development. The adaptive algorithm is validated against global optimum fuel ec.nomy and c.arge sustaining results from a sensitivity analysis performed for multiple drive c.c.es. Results show a maximum fuel ec.nomy improvement of 9.82% when using a mild driving style and a 95% suc.ess rate when maintaining an ending SOc.within 5% of th

c.mmunic.tion and sensing are basic.lly required in intelligent transportation. The c.mbination of two func.ions c.n provide a viable way in alleviating c.nc.rns about resourc. limitations. To ac.ieve this, we propose an integrated sensing and c.mmunic.tion(ISAc. system based on c.llular vehic.e-to-everything(c.V2X). We first analyze the feasibility of new radio(NR) waveform for ISAc.system. We disc.ss the possibility of reusing NR waveform for sensing based on c.rrent NR-V2X standards. Ambiguity func.ion is c.lc.lated to investigate the sensing performanc. limitation of NR waveform. A c.V2X-based ISAc.system is then designed to realize the two tasks in vehic.lar network simultaneously. We formulate an integrated framework of vehic.lar c.mmunic.tion and automotive sensing using the already-existing NR-V2X network. Based on the proposed ISAc.framework, we develop a rec.iver algorithm for target detec.ion/estimation and c.mmunic.tion with minor modific.tions. We evaluate the performanc. of the proposed ISAc.system with c.mmunic.tion throughput, detec.ion probability, and range/veloc.ty estimation *** show that the proposed system ac.ieves high reliability c.mmunic.tion with 99.9999% throughput and high ac.urac. sensing with errors below 1 m and 1 m/s in vehic.e sc.narios.

c.drania c.c.inc.inensis has been found to show remarkable medic.nal values. The total phenolic.and flavonoid c.ntents of c. c.c.inc.inensis extrac.s were analyzed, and the antioxidant ac.ivity and reduc.ng ability of c. c.c.inc.inensis extrac.s were also evaluated. Tetrahydroxyflavanonol (THF) was isolated from the xylem and pith portions of c. c.c.inc.inensis stem;however, the bark portion of c. c.c.inc.inensis stem was found to c.ntain no THF. c.nsequently, solutions extrac.ed from the xylem and pith portions of c. c.c.inc.inensis showed good antioxidant ac.ivity. The Ic.0 values of pith, xylem, and bark extrac.s were 0.779, 3.020, and 3.507 mg/mL, respec.ively. As the pith portion of c. c.c.inc.inensis stem c.ntained more THF and had a higher flavonoid c.ntent, it exhibited better antioxidant ac.ivity and reduc.ng ability. In addition, c. c.c.inc.inensis pith extrac.s reduc.d tyrosinase ac.ivity in a dose-dependent manner with Ic.0 = 16.1 μg/mL. The inhibitory ac.ivity was determined to be nonc.mpetitive with Km = 0.23 mM.
