The article describes the comprehensive methodology of estimation of vehicles active safety characteristics on the basis of results of simulation and road tests data. The methodology could be used for reliable analysis of steer ability and stability that are key parameters of active safety. The analysis of the simulation results of the car when maneuvering, illustrating the relationship between the increase rate of passage maneuver and peak lateral acceleration of the center of mass. The comparison analysis showed good convergence between simulation results and road tests data (deviations of trajectory coordinates, maximum values of longitudinal and lateral accelerations are less than 10…20%). The proposed methodology, the results of simulation and road test data can be used during the design and debugging of various modifications of vehicles in order to choose the most rational design parameters and improve active safety vehicles.
