Simulation of heavy-duty hybrid electric vehicles

Microsoft Excel and ADvanced VehIcle SimulatOR (ADVISOR) were used to simulate the driving conditions of heavy-duty hybrid electric vehicles over various driving cycles in an attempt to optimize their design and control. The fuel economy data thus obtained were compared with those of the in-use heavy-duty hybrid electric vehicles. For this the drive cycles are modified to represent realistic expectations of the dynamic performance of vehicles. The cycles used are "Central Business District" cycle (CBD), "Urban Dynamometer Driving Schedule" cycle (UDDS), "Manhattan" cycle and "City Suburban Heavy Vehicle Cycle" (CSHVC). The vehicle considered for simulations was a transit bus, which is a series HEV. The series HEV is propelled solely by electric motors with energy coming from batteries and an alternator driven by an ICE. The simulation model is based on power requirements for the vehicle taking into account engine, battery, and driveline efficiencies. The control strategy forces the engine to run at a fixed percentage of the power required at the wheels, also taking into consideration battery state of charge correction factor. Further emissions were also modeled for predicting NOx. (Abstract shortened by UMI.).
