Minutes

Communication Framework PoC - moving into implementation start

• vehicle client
  • Philippe reports on the call with Sanjeev (Samsung) (on Monday this week)
  • Ulf: talked to Sanjeev, the two of them will team to work on the vehicle client
• in-vehicle OS
  • Philippe reports on the call with Bosch (on Tuesday this week) about the possible reuse of components from the Kuksa project
  • Sebastian Schildt:  Kuksa focused more on the in-vehicle stuff
  • Gunnar: this was our expectation
  • Sebastian cannot commit to deliver software to GENIVI with any deadline constraint, however he could offer
    
    • a Kuksa target board (1 or 2 samples) which is based on Rasperry Pi and can be plugged to the OBD
    • this OBD feeder could provide some sort of VSS feeder or a lower part of the VSS feeder that could be accessed through Web sockets
  • Tom said he is working on an infrastructure similar to CCS for the eBike project demo, there might be a cool alignment with CCS to look at. He will get back to us.
• detailed design
  • Gunnar: shows the UML diagrams he added to the CCS PoC wiki page, these diagrams represent the relationships between some of the components of the OEM cloud and Vehicle OS subsystems
  • Ulf: it is a good start, it makes things possible
  • Ulf: I am ready to talk about the SignalStore and specially with the Bosch people if they are ready to talk about it
  • Ulf: I thought about the data lake today, I will come with a proposal on next Monday likely, with a presentation, based on the use of a relational database like SQLite
  • Kevin V: the UML diagrams shown are for the vehicle interface, how do we descrie things on the neutral server side
  • Gunnar: in my opinion the UML diagrams could be almost the same on the neutral server to OEM cloud interface,
  • Kevin V: the dependency would be the API definition of the OEM cloud (relates to the graphql schema)
  • discussion follows on the grapql schema content, how the vss tree is represented with it
  • the team agree they need to develop their iwn understanding of a graphql schema
    • /TODO/ Kevin to take sample yaml code of VSS and transform into a graphql schema
    • /TODO/ Philippe to ask Alex whether he can share the graphql he is using with Gunnar

Data categories

• Kevi V: added a couple of comments to the wiki page Data Categories, comments are reviewed
• discussion on the container entity proposed by ISO ExVe standard
• Kevin V: will paraphrase it the container description to stay on the right side of IP
• Kevin V: the container is for the car owner a way to understand for which set of data an OEM ask the car ownerabout his/her consent
• discussion on the naming of entities, some scoping necessary
• TODO Gunnar to update the Data Categories wiki page according to Kevin V comments

How to instantiate the big picture on different vehicle EE / Cloud architectures

• Philippe: this topic has been in the backlog for a while
  • on the vehicle EE side, we need to determine whether we intend to connect to an actual vehicle bus (e.g. using a OBD device or through Ethernet and an Adaptive Autosar ECU, etc.)
  • on the cloud side, we need to think about the deployment of the communication on an infrastructure like AWS using for instance AWS lambda to expose the graphql APIs
  • we need to determine in which versions (i.e. milestones) we want to show the deployment on an actual automotive embedded platform and a cloud-based service infrastructure
  • Philippe: will add this into the Jira backlog

Dissemination - Automotive World Webinar

• Philippe: GENIVI has an opportunity to deliver a new Webinar in the Automotive World Webinars series
• short discussion on whether to deliver it before or after the upcoming virtual tech summit
• (added offline): Mike N (marketing manager) already blocked a timeslot on the 4th of May
• Kevin V is interested in helping for the preparation and delivery of the webinar

Monday,  March  30 - Vehicle Data
