Precrash vehicle velocity determination using inverse system and tensor product of Legendre polynomials - subcompact car class

Presented paper discusses new approach to EES parameter determination in frontal car crash based on the tensor product of Legendre polynomials. In this Subcompact Car Class was analyzed using that method. Data used perform analyses introduced taken from National Highway Traffic Safety Administration (NHTSA) database. Such database consists considerate number test cases along with various information including vehicle mass, velocity, chassis deformation etc. New problem determining necessary due low accuracy currently methods. Linear models up till now for accident reconstruction show significant error as relationship between velocity and cannot be well approximated a flat plane. Proposed model produces better results, because nonlinear dependence said parameters. This also includes calculation example presenting comparison linear method an actual test.
