Technical Paper on In-Vehicle Diagnostic Systems

New SAE International paper "In-Vehicle Diagnostic System for Prognostics and OTA Updates of Automated / Autonomous Vehicles" by Peter Subke, Muzafar Moshref and Julian Erber (Softing Automotive)

The increasing complexity of microcontroller-based automotive E/E systems that control road-vehicles and non-road mobile machinery comes with increased self-diagnosis functions and diagnosability via external test equipment (diagnostic tester).

Technicians in the development, production and service depend on diagnostic test equipment that is connected to the E/E system and performs diagnostic communication. Examples of use cases of diagnostic communication include but are not limited to condition monitoring, data acquisition, (guided) fault finding and flash programming.

The technical paper describes the components of an E/E system that is equipped with an in-vehicle diagnostic tester. The tester consists of standardized components, including MVCI-Server (ISO 22900), ODX (ISO 22901), OTX (ISO 13209) and UDS on IP (ISO 14229-5). The paper also includes a description of cybersecurity measures to protect the vehicle against malicious attacks.

Read the entire 6-page SAE Technical paper (2020-01-1373, 2020) “In-Vehicle Diagnostic System for Prognostics and OTA Updates of Automated / Autonomous Vehicles” written by Peter Subke, Muzafar Moshref and Julian Erber from Softing Automotive Electronics GmbH to learn more about the growing complexity of microcontroller-based automotive E/E systems. 

Based on the SAE International Technical Paper there will also be a Technical Expert Panel Discussion: Next Generation of Prognostics Development at the WCX™ Digital Summit inter alia with Peter Subke! The WCX Digital Summit replaces the SAE World Congress (WCX20).
