ABSTRACT |
The Hybrid Electric Vehicles (HEVs) have additional powertrain components compared with conventional
vehicles. Thus, to design a Vehicle Thermal Management System (VTMS) architecture and control strategy for a new HEV
powertrain, it is necessary to analyze the energy balance in the vehicle powertrain under various driving cycles and
environmental conditions. In this study, a 1-D numerical model for an unmanned military ground vehicle powertrain including
VTMS is developed and cycle simulations under military operation driving schedule with three different environmental
temperatures are conducted to evaluate the cooling/heating performance of the VTMS and the performance of the vehicle. The
simulation results showed that the integrated simulation of the VTMS and the powertrain is useful for the estimation of the
performance of the new concept of VTMS architecture for a new vehicle platform. This study also suggests that the integrated
system model can supply various information for the system design and optimization in the early stage of system design
process. |
