【 摘 要 】

Understanding the vehicle behaviour in the tire saturation region, close to the grip limit, is really important when the safety during vehicle motion is concerned. In case of autonomous vehicle research, usually the so called "safety-margin" is defined to describe this limit behaviour. For this, often a simulation environment is used. These environments can over-simplify suspension parameters that leads to inaccurate results, in such conditions. This paper investigates the effect of these parameters, in a given simulation software, to understand if parameter changes, eg.: roll center height, creates the expected changes in vehicle behaviour. This way it is possible to validate, if the chosen environment is "good enough" for our safety-margin research in the future.
