Abstract
A method of developing a mathematical model of dynamics of a vehicle for use in a computer-controlled simulation, comprising: selecting a coefficient of a state-space model mathematically modelling the dynamics of the vehicle, the selected coefficient having a value for a predetermined state of the vehicle; and varying, a parameter of a physically-based computerized model mathematically modelling the dynamics of the vehicle, the parameter related to at least one of physical characteristics of the vehicle and phenomena influencing the dynamics of the vehicle, to improve the accuracy of the physically-based model via computer-implemented numerical optimization, the computer-implemented numerical optimization targeting the coefficient of the state-space model such that the difference between a value predicted by the physically-based model and the value of the coefficient of the state-space model for the predetermined vehicle state is within a predetermined range.
