The 5th Symposium on In-Vehicle Network and Communication Architecture Technologies and Standards (IVNCAS 2026), hosted by China Automotive Technology and Research Center – China Automotive Standards Institute, has recently concluded. DSA was invited to attend and deliver a topic presentation. Focusing on E/E architecture transformation for software-defined vehicles, DSA’s Product Manager shared the new-generation SOVD service-oriented diagnostic standard and real-world implementation practices, and explored the roadmap of vehicle diagnostic technologies with industry-chain experts.
DSA’s Product Manager delivered the topic presentation From UDS to SOVD: Service-Oriented Vehicle Diagnostics. As a drafting member of the ASAM SOVD standard, DSA has long been dedicated to the development of vehicle diagnostic standards. Combining industry pain points, core specifications of the standard and practical implementation solutions, the presentation shared insights on full-lifecycle intelligent diagnostics for software-defined vehicles. After the session, the DSA team held in-depth technical discussions with on-site experts regarding SOVD standard rollout and challenges in project implementation.

Pain Point Analysis
With the widespread adoption of domain controllers and central computing architectures, the traditional UDS diagnostic protocol has shown growing limitations. It struggles to adapt to in‑vehicle SOA services and lacks standardized diagnostic interfaces for near‑field, remote and on‑board APP scenarios, failing to meet the demand for integrated hardware‑software fault analysis in software‑defined vehicles.
Standard Interpretation
This section elaborates on the new‑generation ASAM SOVD (ISO 17978) service‑oriented diagnostic standard. Built on the REST‑JSON architecture, it features self‑description of diagnostic capabilities and supports multiple diagnostic scenarios including near‑field, on‑board and remote access.
Solution Practice
The complete DSA PRODIS.SOVD solution is compatible with legacy UDS ECUs. It covers the full business chain of engineering development, bench testing, end‑of‑line testing, after‑sales maintenance and remote diagnostics. It provides automakers with full engineering support for SOVD capability building, ranging from standard consulting and toolchain integration to on‑vehicle deployment.
