The main objective of this paper is to establish models of measured real-time data that are obtained in a frontal impact of a vehicle into the rigid barrier. When it tcomes to modeling the vehicle crash we can distinguish two approaches. The first one utilizes CAE (Computer Aided Engineering) software including FEA (Finite Element Analysis) while the second one is based on the System Identification Toolbox , which provides MATLAB® functions, Simulink® blocks, and an app for constructing the models of dynamic systems from measured input-output data. The toolbox also provides algorithms for embedded online parameter estimation.
