Application of Modelica to Development of Future New-concept Vehicles

Recently development of new-concept small vehicles for future mobility societies becomes very active. In this paper, development of simulation models of those new vehicles using Modelica is described. It became clear that such small vehicles tend to have reduced stability and handling ability than conventional vehicles. To cope with this problem, a benchmark problem of designing vehicle control logic for an In-Wheel-Motor vehicle was settled by Japanese society of automotive industries and academia. A brief description about this benchmark study is also given.
