Ideation

ASAM OpenSCENARIO V2.0.0 is being developed in parallel to the already fully released ASAM OpenSCENARIO V1.x branch. V2.0.0 introduces some groundbreaking features. Both branches, V1.x and V2.0 shall merge to one in the future.

The complexity of this Standard, with all the groundbreaking features that are being introduced, means there may be some aspects we overlooked for specific use cases. We want to make sure that the first release of this new version of ASAM OpenSCENARIO V2.0.0 is the best it can be, so we decided to give you, the industry, a chance to begin testing and implementing the Standard before we move to a full release.

The Public Release Candidate will be available until the end of March 2022. Should no further showstoppers be identified, we will then fully release ASAM OpenSCENARIO V2.0.0.

Stay tuned in the new year for news on the webinar series we will be holding to dive more deeply into the Standard (also looking at the differences to the other branch of the already released ASAM OpenSCENARIO V1.x)

In the run up to the full release, the project group will be making no major changes to the Standard in form of this PRC. Rather they will be focusing on making clarifications to content based on your feedback. We want to work together with you to actively begin testing and using the Standard.

The ASAM Implementers Forum will provide the framework for collaboratively discussing, using and implementing ASAM OpenSCENARIO V2.0.0 based on the PRC. The forum has been running in parallel to the development of the Standard and has already been providing valuable feedback to the continued improvement. Now we want to kick things up a notch and fully focus all activity on this forum. The forum has two working groups, one that focuses on using the Domain Specific Language to write scenario descriptions and another that focuses on implementing ASAM OpenSCENARIO V2.0.0, be it in existing tools or new ones.

The kickoff of the Implementers Forum for the PRC took place on Jan 17, 2022.   Review

Background to ASAM OpenSCENARIO V2.0.0

ASAM OpenSCENARIO is currently developed in two separate strands: one to further develop version 1.x and a second one to develop version 2.0. They are independent development strands that run in parallel and will only converge into one version in the future.

V1.x provides a very concrete scenario description format, usable now, that will be directly compatible with the 2.0 project. ASAM OpenSCENARIO V2.0 provides a Domain Specific Language (DSL) and aims to significantly extend the domain addressed by V1.x to cover further use cases for AD development. The two groups will also jointly develop a migration mechanism that grants unchanged run-time behaviour for OpenSCENARIO V1.x scenarios converted to OpenSCENARIO V2.0.

Project Detail

The ASAM OpenSCENARIO V2.0 project is aimed at taking the concepts specified in the ASAM OpenSCENARIO concept paper and continue and develop the next generation of the Standard: ASAM OpenSCENARIO V2.0. 

Based on the considerations of the concept group, ASAM OpenSCENARIO V2.0 is proposed to be founded on the concept of a domain-specific language, that should support all levels of scenario description, from the very abstract to the very concrete in a suitable way. 

The ASAM OpenSCENARIO V2.0 concepts take proven features and capabilities of OpenSCENARIO V1.0, like its event-based scenario execution model, and place them in a more general and expressive language framework to serve as the foundation for both incremental improvements and more revolutionary enhancements.

In comparison to ASAM OpenSCENARIO V1.0, a more detailed set of actions and attributes for the relevant Simulation models shall be defined to allow for a more comprehensive scenario description and to improve exchangeability. This is addressed by the introduction of a domain model.

Beyond such improvements, the proposed domain-specific language supports the creation of more complex scenarios through flexible composition and parametrization of component scenarios in ways that allow realistic, emergent behavior to occur. This is expected to enable massive testing and Verification of new, complex hardware and software systems, and their interaction with the complex environment of driving.

The concept group believes that the proposed concepts and direction will enable ASAM OpenSCENARIO V2.0 to supply a step-function in its ability to describe full, complex simulations and/or tests, addressing all the required elements, and utilizing existing building blocks (like ASAM OpenDRIVE or ASAM OpenCRG).

In order to leverage investments in ASAM OpenSCENARIO 1.x, a clear migration path and compatibility concept is part of the overall concepts for ASAM OpenSCENARIO V2.0.

Implementers Forum

ASAM is hosting the ASAM OpenSCENARIO V2.0 Implementers Forum to support companies in implementing the Standard. The Implementers Forum is also the place to discuss the release candidate of ASAM OpenSCENARIO V2.0.0 before its final release which is expected to be in Mar 2022.
