On the basis of the comparisons of power trains

energy flow

reliability

and cost for each hybrid type

two kinds of parallel hybrid power trains are selected and applied in a certain SUV. The components of the two power trains including ISA

engines

batteries and transmissions are chosen according to their typical configurations and functions. Based on the Advisor software

simulations are carried out in a certain SUV model. The target of the simulations is to achieve a better fuel economy and emission as well as meet the required driving performance. Finally

the results of the comparison between the conventional SUV and the hybrid SUVs are discussed.
