SOVD – Service Oriented Vehicle Diagnostics

The transformation of the electronic vehicle architectures with the entry of high performance computers and thus increasingly software-based systems in the car (see article: The change in the vehicle E/E-Architectures) new challenges also arise for the diagnostic procedures. The next evolutionary step in the self-diagnosis of electronic control units (ECUECU – electronic control unit – is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle. ECU in new cars control every feature a car has and are becoming more and more important in the development of automotives. More) is to be expexted. Under the name Service Oriented Vehicle Diagnostics (SOVD), the Association for Standardization of Automation and Measuring Systems (ASAM) is currently preparing a standardized API for diagnosting and communicating (also OTA-Updates) with software-based vehicles (see article: Innovation 2022 – CCI Study).

Objectives:

• an API (Application Programming Interface) for diagnostics and software update (OTAOTA – automotive over-the-air- is the new way cars use to automatically update their firmware and software. The manufacturer uploads the update data to a cloud, which is then forwarded to the car via a mobile connection, where it must be confirmed by the car owner, then installed, and finally feedback is sent back to the OEM. More).
• A consistent API that can be used for new systems and traditional...
