Policies

  • It is expected that all meeting participants have read the compliance statement. Every meeting will start with a reminder.

  • Strive for making signal objects reusable by other signal specifications.

Meeting notes  2025-04-07

  • Compliance statement

  • Welcome and agenda discussion - anything that needs to be added?

  • Prioritized Topics:

    • Continue the Truck tree analysis.

      • The discussion led to the understanding that any single signal is a potential candidate to be removed, and that there must be a practical solution to that. The VariationPoint feature can do it, but it is not a scalable solution if large numbers of signals needs to be removed.

        • Different options were discussed, both subtractive (removal from VSS-core) and additive (pick from VSS-core).

        • The discussion will continue, and hopefully different solutions will be proposed.

    • Overview HIM configurator features.

    • Review of the CVIS status AMM presentation (draft version).

    • Ted: Regulatory signals

  • Prioritized Topics:

    • HIM configurator  generated Truck tree analysis

    • AMM presentations

      • "Status update of the Commercial Vehicle Information Specifications (CVIS) project" is scheduled 04:20 - 4:40pm on May 14

      • "An Automotive API and Data Model that caters to all types of vehicles" is scheduled 02:00 - 2:25pm on May 14

      • Paul: It is possible to have additional break-out meetings. Please consider the need for this until next meeting.

    • Overview HIM configurator features

      • Moved to next meeting.

    • HIM configurator syntax

      • Sergej proposed that the vspec2 syntax is extended to support Google template syntax, thus enabling logic operations.

      • Ulf proposed that this logic is implemented using any computer language in a tool that generates the JSON based input files to the HIM configurator, and keeps the "simpler" syntax in the vspec2 files.

      • Both proposals can exist in parallel, they will lead to the same end result - configured signal trees in the formats set by the used VSS-tools exporters.

  • Prioritized Topics:

    • Him configurator on Windows

    • HIM configurator road map

    • AMM presentation

    • VSS-core - no compromises

      • The VSS-core tree is vehicle type agnostic. The HIM configurator configures it into a vehicle specific tree.

      • This concept is applicable to most vehicle types like Car, Truck, Bus, Van, etc.

Meeting notes  2024-11-04

  • Compliance statement

  • Welcome and agenda discussion - anything that needs to be added?

  • Prioritized Topics:

    • VSS car tree vs CVIS truck tree.

      • Arguments for a separate truck tree

        • The HIM model supports to rename the root node so that selected parts of the tree can have identical paths with the VSS tree.

        • The objects branch in CVIS facilitates a structured model for sharing common branches.

        • Parts of the VSS tree does not relate well to Trucks, e.g. Axle/Wheel configuration.

        • The HIM configurator provides features not available in VSS-tools, such as the assymmetric matrix configuration.

      • Decision: We will continue the development of a separate Truck tree.

        • The scenario where an app developed for passenger cars should also be deployable on a truck will be supported.

  • Prioritized Topics:

    • Future of the meeting 

      • Volvo: sees interest in defining trees and also in using VISS. Still internal discussion.

      • GM going through reorg, currently monitoring this group.

      • Initial conclusion: We will continue the meeting series.

    • use vsspathlist.json to vet the content of the Truck tree.

      • Maybe not the right path forward, see question below.

    • Should a truck use the VSS tree (Vehicle tree) instead of defining a separate tree?

      • Trailer, Driver, etc. could be separate trees, but Truck should use the Vehicle tree (at least as much as is feasible).

        • How to resolve major differencies, e. g. the axle/tire location definitions?

    • Plan for how to create a first version Truck tree (trailer/bus?).

    • VISSR updated with VISSv3.0 features now supports multiple trees, e. g. Truck tree plus Trailer tree(s).
