In this paper author introduces problem of the reduction of diagnostic information in evolution condition machine for estimating state prognosis algorithms which are the basis for determining conclusion rules for estimating the next machine operation term and for state genesis which is the basis for rules creating of machine state estimation in the past. Automation of the investigation system of the evolution of the technical systems machines condition in which diagnosing distinguishes itself of prognose of the state and the genesis of the state requires the qualifications of the gathering of diagnostic parameters describing the change of the condition of the machine during exploitation. The results of investigations connected with the implementation of the procedures of monitoring the technical machine engines condition and their investigation for the chosen arrangements of mechanical vehicles were introduce
