Title: Mechanical Mathematical Modelling of a Car Accident Caused by Sudden Keywords: Automobile, Active suspension, Dynamic model, Failure, Matla Abstract: Design of modern automobiles focuses greatly on passenger safety in vehicle cabin by creating intelligent systems to control dynamically changing parameters, as it is the case with road-and-tire friction coefficient. Problems surrounding the occurrence of sudden technical malfunction in the vehicle and the control of its behaviour after collision seem to be extremely complicated. In these circum-stances, it is basically relied on driver professional skills and their ability to maintain sustainable vehicle behaviour applying existing active and passive safety systems. Such accidents cannot be predicted in time and therefore it is good to analyze them in dynamic aspect as well as to model the expected unwanted changes in motion direction. This article offers a dynamic vehicle model with six generalized coordinates. It takes into account car suspension, damping of shock absorbers, the variable road-and-tire friction coefficient as a function of the contact point speed, the car motion in References Issue
