Original Abstract

Získané poznatky z uvedeného pojednání mohou být zobecněny do zásad metodiky postupů analytiků silničních nehod při rozborech obvyklých jízdních vlastností vozidel v nehodovém ději, s cílem harmozizace a standardizace postupů ve znalecké praxi.

English abstract

For the purpose of the submitted dissertation, 66 measurements were carried out on two different models of the Skoda Fabia car. The results of the lateral acceleration measurements were compared with the analytical calculations and the simulations processed by PC-Crash. The comparison has shown that as long as the principles of technically acceptable range of input values are kept (the adhesion coefficient and the reachable lateral acceleration in particular), there is very good agreement between the measurement results and the analytical calculations and the simulations of motion. When making use of the software models, it is vital to gather as much information as possible about individual elements of the evaluated system "person - machine - environment". It is necessary to emphasize that unlike in the experiments, the fulfilment of this criterion in current expert practice is not easy at all. The findings of this dissertation can be generalized into methodological principles that will be used by road accident experts for analyzing the current driving properties of vehicles within the accident action, with the aim of harmonizing and standardizing the procedures in the expert practice. The expert standards supplemented with the new methodological findings will become a very important and useful tool, especially with regard to the dynamic way of introducing new electronic systems into the car chassis in the production of modern vehicles.
