In this paper, certain examples of comparison between the selected definition of the stochastic technical stability (for motor vehicle models) and the ISO definitions (developed for real vehicles) have been discussed. Being able to refer the examined stability of a mathematical model to the real object may result in verifying the properties of the latter on the basis of model tests, instead of the field trials. Such an attempt has been presented previously, but in a more general approach. The aim of this paper is to present a certain attempt to compare the results obtained for a simulated vehicle model in virtual environment with the specific definitions of stability dedicated to the real motor vehicles. The background of this considerations liesin the examination of the stochastic technical stability, which allows any mechanical system undergo external random disturbances, such as road irregularities.
