Historically, vehicle safety reflects the current state of the art and new innovations will continue to make our cars even safer in the future. Since its invention, the car has enjoyed a unique, triumphal procession. Safety plays a central role in the development of a car model today. The number of accidents has also risen, in line with the growth in traffic. In addition to carelessness or distraction at the wheel, the most common causes of accidents are excessive speed, risky maneuvers and disregard of traffic rules. The introduction of the speed limit on rural roads and the obligation to wear seat belts, were particularly important positive milestones. Two different methods are also used to check the effect of the individual technical options and safety, in the event of accidents. First are the crash tests. Here, an accident situation is simulated in practice, under realistic conditions. The other solution is the simulation. The Finite Element Method, behind this term, lies the virtual calculation of various consequences of an accident, on the basis of mathematical differential equations. The degree of deformation of various components or the entire car, as a whole, is examined by calculation.
