“…Технічна діагностика вузлів та агрегатів дорожніх транспортних засобів (ДТЗ) одержала свій розвиток у вигляді автоматизованих систем контролю. Діагностичні комп'ютери LAUNCH, BOSCH, MATCO, ZECA та інші дозволяють контролювати всі електронні системи ДТЗ, включаючи комплексну систему управління двигуном [1,2,3]. Проте, вони не дозволяють повною мірою продіагностувати механізми двигуна, зокрема, саму підвладну зносу і несправностям циліндро-поршневу групу (ЦПГ) двигуна та клапана групу, які забезпечують герметичність камери згоряння.…”

Informative dampers and installation methods do not dose the speed, accurately distinguish the nature of the injustice of the cylinder-piston group and check the tightness of the valves of the single-stage model of the engine, which allows a preliminary quality assessment in the production assessment. . During the inspection, the activity of the "black box" is checked for unknown structural elements, the initial diagnostic obligations that affect. The nomenclature of structural parameters that are checked is determined in accordance with existing standards. Based on the advanced model development method produced by the technical condition of the cylinder-piston group and the sealed valve of the engine, model, detailed dosing, statistical information, machines, machines, machines, machines, machines, machines, machines, machines and equipment. first, to localize the unevenness of the cylinder-piston group and the tightness of the engine valve, and secondly, to formally process the process of automated technical diagnosis; thirdly, it will provide a high rate of indiscriminate diagnosis. To assess the sensitivity of the diagnostic value as a random variable, it is proposed to evaluate not the relative change in the limit and nominal value of the controller, the relative change in the average value of the random variable within the allowable value. The diagnostic parameter is considered stable if the condition under which the absolute maximum value from the average value does not exceed "three sigma" is fulfilled. Informative in consideration is the diagnostic parameter in which the ratio of the difference between the average significant value of the random control in good and faulty state of the object to the difference of standard deviations exceeds one. Expert assessment of the technical condition of the road vehicle is associated with the determination of diagnostic parameters, structural parameters, as well as the reasons that caused the change of these parameters.

“…First, the impossibility of assessing the impact of DPC on compliance with DWRR [28]. Secondly, it is impossible to assess the influence of parameters of the vehicle technical condition, DPC, and DWRR on fuel consumption [29]. Thirdly, it is complicated rational management of vehicle operation parameters under operative mode, taking into account road and operating conditions [30], etc.…”

Parameters of the technical condition of transportation means in modern transport-logistics and infrastructure systems are an integral element of their communication support. This is enabled by the use of remote information monitoring technologies in control processes. The object of this study is the processes of vehicle remote monitoring in terms of determining the technical condition. The work addressed the task of improving the process of vehicle technical operation through the construction of a model of the remote monitoring system of its technical condition. A remote version of the information-analytical monitoring system was implemented. The work considers the system interaction of the means of remote monitoring of the state of a vehicle to ensure control under the operating conditions of the driver's work and rest modes. Road, transport, climatic conditions, etc. were taken into account. Considering these features, an information and analytical model of the system for remote monitoring of vehicle condition was built. Features of the subject area of the system are described using a DFD diagram. A structured information model of the information-communication system has been constructed, which has the ability to actually provide vehicle remote monitoring, the driver's work and rest modes, and his/her physical condition. The results, subject to the use of the V2I information model in the field of transport, allow remote monitoring of the vehicle technical condition. Specifically, to analyze the influence of changes in the physical condition and modes of work and rest of drivers on changes in the vehicle operating parameters
