"利用SOVD API实现车辆诊断服务的标准化项目探索与实践"

The document "2_ASAM_SOVD_Wenzel.pdf" outlines the key points discussed during the presentation on SOVD (Service Oriented Vehicle Diagnostics) by Tobias Weidmann from Vector Informatik GmbH and Bernd Wenzel from ASAM e.V. The presentation took place in Munich on the 7th and 8th of October, 2021. The focus of the presentation was on the SOVD API and access to classic diagnostics through the standardization project. The motivation behind the development of SOVD was driven by the increasing complexity of modern vehicles, which are equipped with multiple hardware processing cores, multiple applications, and multiple virtualized operating systems. These highly sophisticated vehicles require continuous functional contributions from apps, electronic control units (ECUs), and backend systems. Additionally, the increasing trend of software updates and over-the-air (OTA) updates for vehicles means that the development of vehicle functionality continues even after the start of production (SOP). This seamless integration of Unified Diagnostic Services (UDS) based diagnostic backend was the catalyst for the development of SOVD. One of the key factors driving the shift towards SOVD was the limitations of UDS, prompting the question "Why not UDS?". The presentation highlighted the challenges and limitations of UDS, paving the way for the development of SOVD as a more comprehensive and effective solution for vehicle diagnostics. Overall, the presentation emphasized the need for a more adaptable, efficient, and standardized approach to vehicle diagnostics in order to keep up with the evolving technology and complexity of modern vehicles. The SOVD API and the standardization project are crucial steps towards achieving this goal, providing a platform for seamless integration and continuous development of vehicle diagnostics throughout the lifecycle of the vehicle.
