Abstract:
This paper deals with the modeling and validation of a complex vehicle dynamics model implemented in Matlab, which should enable real-time simulation. In detail, the powertrain and the tire model Magic Formula by Pacejka are presented. In addition to the horizontal dynamics, which can also be found in single track models, the here presented vehicle model also takes into account the vertical motion as well as the pitch and roll behavior. Furthermore, the wheel load fluctuations during the driving maneuvers are included. The equations of motion are based on multi-body dynamics. Based on three driving scenarios, which are simulated in the software CarMaker, the quality of the driving dynamics model is evaluated.
