Analýza diagnostické komunikace DoIP v moderních vozidlech

Abstract

This bachelor’s thesis examines the analysis of diagnostic communication in vehicles that use the Diagnostic over Internet Protocol (DoIP). The introductory section describes the principles of automotive diagnostics, the structure of the Unified Diagnostic Services (UDS) protocol, and the DoIP protocol defined by ISO 13400. The practical part of the thesis focuses on the interception and analysis of diagnostic communication in a Škoda Enyaq vehicle. The captured communication was analyzed at the DoIP and UDS protocol levels. This thesis describes the structure of individual diagnostic reports and uses specific examples of real-world data to demonstrate the diagnostic session between the tester and the vehicle.
