A Fuel Cell Electric Vehicle(FCEV) is one of the future vehicle alternating conventional vehicle caused by zero-pollution and higher economical efficiency. Conventional vehicle used the engine with power train but a FCEV uses the motor with power train. In order to develop and evaluation FCEV system in short developing period, a virtual chassis platform of the FCEV is necessary. Virtual simulation tool for existing fuel cell vehicle uses simple vehicle model. Comparative study of multibody vehicle model and simple vehicle model is necessary because the chassis of electrical fuel cell vehicle has different mass distributions comparing with conventional vehicle, due to configuration of a hydrogen tank, fuel cell stacks, heat system, etc. In this paper, a virtual chassis platform has been developed based on multibody vehicle model and mathematically permanent magnet synchronous motor model. The virtual chassis platform has been validated by the stop and go simulation to analyze differences of multibody vehicle model and simple vehicle model.

A Fuel Cell Electric Vehicles (FCEV) is one of the future automobile technology alternating conventional vehicles which use fossil fuel. It will be a standard in the future automobile market with zero-pollution and higher economical efficiency. In order to develop and evaluate FCEV system in short developing period, virtual test methods are necessary. In this paper, a virtual chassis platform has been developed based on multibody vehicle model and experimental data in order to evaluate FCEV systems. The virtual chassis platform has been validated by the stop and go simulation with several cases of power management strategy. Cornering test of multibody FCEV model has been also carried out in order to understand dynamic characteristics different from conventional vehicles.

Recently, due to the resources and environment problem, the green energy vehicles have been developed. The motor and its controller are most important parts. In this paper, the mathematical model of the interior permanent magnet synchronous motor and its controller has been developed for the simulation based design of the green energy vehicles. The dynamics parameters of the model can be easily changed during the simulation. The developed model has been compared and verified with the commercial program named Autonomie.
