In the article, the car safety control is simulated because of the change of its technical condition during operation using the functional resonance analysis method. The object of the study is car safety control because of the change of its technical condition during operation using the functional resonance analysis method. The purpose of the article, based on the method of functional resonance analysis, is to simulate the car safety control because of the change of its technical condition, which affects the deterioration of steerability, stability, smoothness and unning characteristics during operation. The research method is simulation modeling. To ensure the proper technical condition of the car, the technology of its maintenance has been analyzed. The practical processing of statistics is implemented using the ResilienceDS tool. On the basis of statistical data, the reasons for changing the technical condition of the running gear of the car and their influence on the operational properties were analyzed. ResilienceDS hardware is used to achieve this goal. Such a tool allowed us to model the socio- technical system "Human-Car-Organization of maintenance system" and to form formal models for the continuous evaluation of the stability and conditions of increasing the operation of cars. The data collected on the service station of cars was used to develop a maintenance model by the functional resonance analysis method. The model consists of a set of features that describe the steps taken to service a car. Simulation of the influence of the running gear technical condition on the performance of the car by the functional resonance analysis method has certainly revealed that car maintenance is a complex activity. The model by the functional resonance analysis method gave an idea of how successful and high-quality car maintenance works depend on the complex interaction of several of its parts that work in the technical system. Relationships are so complex that they are almost impossible to perceive. Thus, the important socio- technical mechanisms of the system "Human-Car-Organization of maintenance system" that regulate the relationship between functions. These can be informal, human mechanisms or specific tools, such as the level of technical condition of the car, the technological process of service, instructions and regulations of the repair team. The simulation of the influence of the technical condition of the undercarriage on the performance of the car by the functional resonance analysis method showed that considerable attention should be paid to elemental diagnostics. The performance of these functions is based more on current knowledge of the design of a new generation car and its maintenance technology, thus, may be more volatile.
