There were presented the results of computational simulations of curvilinear and three- dimensional motion of vehicle, which were done with software for a reconstruction of road accidents. The paper also presents the results of real experiments, which were performed with a motor-car. The values of acceleration and angular velocity were the results of simulation. These results were generated for a coordinate system of vehicle and used for further analysis. In case of real vehicle, the above mentioned parameters of motion were measured with three-axial accelerometer sensors with piezogyroscopes from Analog Devices company - these sensors were mounted on the vehicle roof. Simulation data was used to create and verify the transformation method of acceleration from the vehicle coordinate system to the global coordinate system of a position of mass centre of vehicle. The results obtained from this method were correct. Next the attempt of performing of the similar transformations for the results of measurement of real motion of vehicle with a set of sensors was done. The obtained results of simulations and experiments were compared. The reasons of discrepancy between obtained results were shown.
