【 摘 要 】

One of the basic tasks of the accident reconstruction is to define values of parameters of participants of the accident before its actual occurrence. The assessment of correct behaviours is made and the court decides whether the accident participants are guilty or innocent. Therefore, the credibility of specific values is essential. The use of so-called accident recorders - EDR/ADR type of devices, as an alternative compared to classical methods for accidents reconstruction - has become more common over the past years. The paper includes basic notions related to this type of devices, describes potential sources of uncertainty of the car motion reconstruction results, obtained on the basis of their records. Exemplary results of calculations made with simulation methods are presented (but using experimentally verified models).The examples presented confirm their usefulness, however, they also indicate possible significant errors in the motion parameters assessment if simplified devices are used.
