There is a problem of short-term or long-term forecasting of abnormal status of frictional bonds in mechanical systems and control of their dynamic characteristics. To solve this problem, we suggest using the status control of tribosystem according to the analysis of integrated estimates (dissipation function, degrees of dissipation, the power losses of frictional system led to an exit and a quadrantic module of coherence), a stability margin on amplitude and phase of amplitude and phase–frequency characteristics (APFC). These estimates influence the given quantity of the peak factor which defines sensitivity of systems of automatic regulation to tribosystem parameters. It is also the sign of transition from one stationary status to another. During tribospectral identification of pre-slippage, the fixing of corresponding integrated characteristics is a signal to give activator of clutch in wheel and rail contact. It allows increasing traction effort of the locomotive and decreasing its speed for the drop of traction capacity of wheel–rail system.
