Course abstract

The aim of the study course is to acquire vehicle diagnostics as an essential component of technical maintenance. Students get acquainted in depth with the process of diagnosing vehicles and their units, methods using modern diagnostic tools. Gets acquainted with the organization of diagnostics and related technological processes in service companies. In the laboratory work, students have the opportunity to perform practically all components of the diagnostic process - diagnosis, determination of the technical condition, forecasting of the remaining work resource, as well as to get acquainted with modern diagnostic tools and methods.

Learning outcomes and their assessment

Knowledge - Master's students acquire in-depth theoretical and practical knowledge, understanding of the technical diagnostics of vehicles and the organization of related processes in car service companies, the latest diagnostic methods and equipment. The acquired knowledge can serve as a basis for further creative and professional development. Assessment - a test.
Skills - Master's students are able to creatively use the acquired knowledge in the field of vehicle diagnostics, are able to independently use theory, methods and problem-solving skills to perform research or highly qualified professional functions. Ability to evaluate and make decisions in difficult situations. Assessment - a test.

Competence - Master's students are able to independently analyze complex scientific and professional problems, justify decisions, and, if necessary, perform in-depth analysis of problems. They are able to integrate knowledge from various fields in the development of professional activities and the development of new diagnostic methods. During the semester, knowledge and skills are controlled with 2 examination tests, one independent work, as well as laboratory work and their reports.
