Open Source Summit Japan & Automotive Linux Summit 2021

Data from automotive ECUs and sensors may be generated in many forms. There are significant challenges in managing both the flow (the buffering, transmission, and reception) and the use (storage, access and presentation/analysis) of data that may take so many forms and formats. There are cloud-based tools to manage data formatting and structure once it is present in the cloud. But the challenge remains of how unstructured data can be transited to the cloud. This presentation addresses liaison activities between two standards organizations. The eSync Alliance and GENIVI Alliance are developing specifications to standardize the data that flows from ECUs and sensors to the cloud, addressing how to extract, organize and distribute data to the ecosystem. The collaboration implements the eSync standardized bi-directional OTA data pipeline for the Vehicle Signal Specification (VSS), which is being built as part of the CVII (Common Vehicle Interface initiative), a joint outreach from GENIVI and W3C to the automotive industry. The paper will describe the first collaborative document which details VSS OTA Metrics to catalog data for various ECUs, and the Proof-of-Concept activity of the liaison team to examine the practical application the specifications in a working platform.
