Abstract: The paper presents an approach for simulation model development adapted for low-cost simulators serious games, based on mathematical modeling of vehicle dynamics which sufficiently well represents functional motions of class of simulated ground vehicles.  The model is simple, easy to use and suitable for efficient model development and validation. By tuning the parameters of the basic generic model it may be obtained particular behavior of various mobile objects (tanks, tracks, cars, mobile robots) implemented in simulators.

An example of passenger car dynamic model, implemented in serious game- driving simulator, is described to illustrate feasibility and features of proposed modeling procedure. Initial modeling is done using parameters extracted from technical specifications af the vehicle and Matlab/Simulink model validation. The Matlab model is used to check and validate real-time simulation model. The final step of model tuning and validation is done using comparison of operative simulator model and the data recorded on real vehicle.
