Vehicle Model Complexity How Much is Too Much 940656

Simulation studies are widespread in vehicle handling/dynamics analysis. Over the years, many researchers have developed vehicle models ranging from a simple half-car model to a very detailed model. There is a general perception that a detailed model is guaranteed to yield a better result; yet it should be noted there are no recommended or standard procedures to measure vehicle parameters required for simulation studies. Recent studies have revealed that different measurement procedures could lead to significant differences in the measured parameters. This paper discusses the issue of model complexity in the context of available input parameters, especially tire data. Also, for vehicular application, the lumped parameter modeling approach and multi-body formulation approach advantages and disadvantages are discussed.
