SELECTION CRITERIA FOR TECHNICAL DIAGNOSTIC SYSTEMS AND INFORMATION TRAINING OF MOTOR VEHICLES
Ключові слова:diagnostics, forecasting, probabilistic method of forecasting, model of the object technical diagnostics, control systems, monitored parameters
The aspects of the development of criteria for the selection tools and options for systems of technical diagnostics of vehicles are considered. Monitoring systems and forecasting the technical condition of vehicles will require expanding the range of monitored parameters. The above criteria for assessing the selection of the optimal set of measured parameters and their means of measurement to ensure the effectiveness of the developed systems monitoring and diagnostics. The main aspects of information preparation diagnostics and repair of motor vehicles are given.
The system approach to the issues of technical diagnostics of vehicles requires consideration of the system of quality management maintenance and repair as an integral part of management. The system of quality management of technical maintenance and repair serves to ensure a given level of the coefficient of technical readiness, reliability, durability vehicles, efficient use of them with minimal financial and labor costs. Thus, the quality management system of motor vehicles is based on a set of measures, which include technical, economic, and other interrelated actions to achieve the objectives set to achieve a high level of quality.
In developing the system for monitoring, diagnosing and forecasting of vehicles one of the important tasks is to determine the optimal set criterion for a set of measured parameters and their means of measurement, which ensure the economic efficiency of the control system.
The article notes that the main drawbacks of these criteria can be called either the requirements of a large amount of a priori information, which is often impossible at the design stage of the control, diagnosis and forecasting system, or insufficient account of the components of the quality controls and diagnosis, such as the duration and completeness of control.
The problem of quality in the maintenance and repair of motor vehicles is largely determined by the level of metrological support. Technical diagnostics involves determining the technical state of the diagnostic object with a certain accuracy. Therefore, to ensure the quality of the system of maintenance and repair of motor vehicles, it is necessary to use the principles of metrological support.
