| Abstract: |
A
hybrid electric vehicle simulation tool (HE-VESIM) has been developed
at the Automotive Research Center of the University of Michigan
to study the fuel economy potential of hybrid military/civilian
trucks. In this paper, the fundamental architecture of the feed-forward
parallel hybrid-electric vehicle system is described, together
with dynamic equations and basic features of sub-system modules.
Two vehicle-level power management control algorithms are assessed,
a rule-based algorithm, which mainly explores engine efficiency
in an intuitive manner, and a dynamic-programming optimization
algorithm. Simulation results over the urban driving cycle demonstrate
the potential of the selected hybrid system to significantly improve
vehicle fuel economy, the improvement being greater when the dynamic-programming
power management algorithm is applied. |
