SAE On-Board Diagnostics Symposium Americas
Talk by Bernd Wenzel, Senior Technical Consultant at ASAM e.V.
on: Sep 08 - 11, 2025 | Garden Grove, CA, USA
Bernd Wenzel, Senior Technical Consultant at ASAM e.V. and ASAM SOVD expert, presents "ASAM OTX Extension for ASAM SOVD - Usage of the ASAM SOVD API in test sequences" at Society of Automotive EngineersSAE On-Board The subsystem of an ECU or ECU networks, which performs error detection, handling and communication.Diagnostics Symposium.
ASAM Open Test Sequence Exchange Format (ISO & ASAM Standards)OTX Extensions define a domain-specific programming language designed to describe test procedures. It enables consistent development, maintenance and sharing of test sequences across different lifecycle stages, incl. development, production and service. In recent months, this project group has worked on two key extensions: one for ASAM SOVD and one for JSON. This lecture will explain the concepts behind these extensions and illustrate how they define datatype exceptions, terms, and actions.
The extension for ASAM SOVD is based on the following approaches:
- The ASAM SOVD extension is based on the ASAM OTX extension for JSON.
- OTX StructureSegments simplifies the usage of JsonObjects.
With the newly available ASAM Open Test Sequence Exchange Format (ISO & ASAM Standards)OTX extension for ASAM SOVD, diagnostic sequences can be defined according to the International Organization for StandardizationISO Open Test Sequence Exchange Format (ISO & ASAM Standards)OTX A document, which describes in detail the interfaces and behavior of a technical system for the purpose of implementing, integrating and operating the system.Specification and realization concept, including graphical authoring support.
The lecture will conclude with a status update on the ongoing development of both standards ASAM SOVD and ASAM Open Test Sequence Exchange Format (ISO & ASAM Standards)OTX Extensions.
