Abstract

Holistic, real-time capable models, which are able to describe the overall 3D vehicle dynamics and nonlinear wheel suspension behaviour, are necessary for different applications like, e.g., control system design and HIL test system operation. In this paper a vehicle dynamics modelling approach is presented together with a methodology to derive the equations of motion and adapt them to special applications like simulating a vehicle on a test bench. With the presented methodology and by using symbolic computation, the equations are obtained in analytical form with a minimal set of ordinary differential equations. The equations can be easily manipulated, simplified and evaluated according to the given task. This is especially valuable for overall vehicle test benches, wherefore the equations are needed for model-based control design and parameter identification. To prove the simulation environments' validity, the resulting vehicle model for road applications is compared to commercial, state of the art vehicle dynamics simulation tools.
