74 IT and Automotive The Changing World of After-Sales Diagnostics The Challenge of Workshop Solutions with Software-defined Vehicles – SOVD in Action By Oliwier Sochor, product manager for after-sales diagnostics at Softing Automotive Electronics GmbH In modern vehicles, comfort, safety, and efficiency are increasingly defined by software. Due to the increasing amount of software in vehicles, there is a clear trend toward high-performance computers (HPC) that provide the necessary computing power and serve as an integration platform for the ECUs that have been replaced. This technological evolution is changing not only the vehicle itself, but also what is required in terms of diagnostics. SOVD (Service Oriented Vehicle Diagnostics) is a new standard that defines a uniform communication interface between vehicles and external diagnostic systems. Softing TDX is the perfect solution for keeping pace with the new system architecture and successfully supporting change in after-sales. SOVD – The Diagnostic Standard for Software- Defined Vehicles The SOVD standard describes a service- oriented programming interface (API) for a diagnostic system integrated in the vehicle. The SOVD server running on an HPC there provides standardized diagnostic functions that can be controlled by a repair shop tester. SOVD massively reduces interface complexity and creates the basis for uniform processes throughout the entire vehicle life cycle. Various use cases can be addressed: y Diagnostics on site on the vehicle (proximity) y Remote access, e.g., for expert support from technical centers y In-vehicle diagnostics, e.g., for continuous state monitoring (Vehicle Health State) Graphic: © Softing Automotive Electronics GmbH Standardized Vehicle Access: Proximity, Remote, In-Vehicle Diagnostics Remains the Core Task – But is Undergoing Fundamental Change Classic diagnostic tasks such as reading error memories, software updates, parameterization, and commissioning are also part of the standard repertoire for service-oriented diagnostics. However, SOVD fundamentally changes the diagnostic architecture: GUI, business logic, and all repair and maintenance-related content (e.g., instructions, videos, warehouse connection) remain in the tester. The connection to administration systems (e.g., warehouse logistics, invoicing) will also continue to be handled by the tester. To the webinar
