![]() 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. 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. V1.x provides a very concrete scenario description format, usable now, that will be directly compatible with the 2.0 project. They are independent development strands that run in parallel and will only converge into one version in the future. If you would like to take part in the discussion, join the Implementers ForumĪSAM OpenSCENARIO is currently developed in two separate strands: one to further develop version 1.x and a second one to develop version 2.0. The kickoff of the Implementers Forum for the PRC took place on Jan 17, 2022. 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. Now we want to kick things up a notch and fully focus all activity on this forum. The forum has been running in parallel to the development of the Standard and has already been providing valuable feedback to the continued improvement. The ASAM Implementers Forum will provide the framework for collaboratively discussing, using and implementing ASAM OpenSCENARIO V2.0.0 based on the PRC. ![]() We want to work together with you to actively begin testing and using the Standard. Rather they will be focusing on making clarifications to content based on your feedback. 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. 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) Should no further showstoppers be identified, we will then fully release ASAM OpenSCENARIO V2.0.0. The Public Release Candidate will be available until the end of March 2022. 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 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. Both branches, V1.x and V2.0 shall merge to one in the future. V2.0.0 introduces some groundbreaking features. The following files demonstrate such a translation through an example translation of the ALKS Lateral Detection Range scenario specified in SDL to ASAM OpenSCENARIO and OpenDRIVE formats.After almost two and a half years of intense development work by our members, ASAM is proud to share the Public Release Candidate (PRC) for ASAM OpenSCENARIO V2.0.0.ĪSAM OpenSCENARIO V2.0.0 is being developed in parallel to the already fully released ASAM OpenSCENARIO V1.x branch. The ASAM OpenX formats for scenarios are supported by several simulation platforms and it is possible to translate SDL to ASAM OpenSCENARIO and OpenDRIVE formats. The grammar definition provides a low-level definition of the SDL syntax which is essential if you need to create an SDL parser for use-cases such as converting SDL to another language, or translating SDL into simulator code.ĭownload Grammar SDL Translation to ASAM OpenX Formats (OpenSCENARIO, OpenDRIVE) The SDL specification is a more in-depth resource on the SDL language with more complex examples.ĭownload Specification SDL Grammar Definition (preview) The user guide is a useful initial resource for anyone wanting to write scenarios in the SDL language. Toolchains also exist for translating SDL to ASAM OpenScenario and OpenDrive. It is also machine-readable which enables scenario definitions to be fed into testing toolchains, and other ADS development tools, and is simulator independent meaning that it can be readily translated into simulator specific code for executing scenarios in a simulator, current toolchains existing for the CARLA simulator. ![]() ![]() SDL has been developed with the primary objective of being human-readable so that it can be understood by all users involved in developing ADS. The Safety Pool Database uses the Scenario Definition Language - SDL - developed by WMG as the preferred language for defining scenarios within the database. ![]()
