Summary:

High-powered vehicles offer an advantage of superior fueleconomy through use of regenerative braking and lowered transientemissions by reducing the operating portion of the engine to followload as closely as in a conventional bus. A hybrid bus was designedand a prototype was developed. It has a parallel-type hybridpowertrain system and uses a 6-liter diesel engine which satisfyEuro-5 emission standard. 44-kW-electric motor, AMT (automatedmanual transmission) and Li-ion-type batteries were applied to thishybrid bus.Total 8 hybrid buses are test-running in 6 cities and thedriving performances are monitored in terms of fuel efficiency,emission and convenience. This paper presents the performance,major component features and calibration procedures of hybridpowertrain systems. Test run monitoring result showed a benefit offuel economy at least 36% by comparing to a conventionaldiesel-powered bus. Chassis dynamometer tests were also carried outand hybrid bus showed 42% ~ 54% higher fuel efficiency and lowemission levels than diesel bus. So it is expected that this systemmay become a cost-effective alternative drive for next medium andheavy hybrid vehicles
