The authors examine in detail the fundamentals and mathematical descriptions of the dynamics of automobiles. In this context different levels of complexity will be presented, starting with basic single-track models up to complex three-dimensional multi-body models. A particular focus is on the process of establishing mathematical models on the basis of real cars and the validation of simulation results. The methods presented are explained in detail by means of selected application scenarios.
This text explains the basics of vehicle dynamics and offers the rules for building simulation models, thus enabling the reader to develop his own simulation model for vehicle dynamics and to apply commercial simulation programmes.
