Public Review

Involving all ASAM members to ensure high quality, usefulness and implementability of our standards.

Public Review

ASAM is asking for feedback on release candidates for upcoming new standards or major versions prior to their release. Purpose of this review is to improve quality and efficiency of the standards.

We ask all experts to provide their feedback by leaving comments in the release candidate. Please check particularly for:

completeness: Are there any missing parts or features that are required to use the standard?
unclarities and ambiguities: Are there any terms, definitions or content parts that are imprecise, unclear, not (sufficiently) defined or not understandable?
inconsistencies: Are there any terms, definitions or content parts that contradict each other or are incompatible with other parts of the standard? Is the structure and line of reasoning plausible and consistent?
usefulness: According to your expertise, is the standard practical and useful? Does it meet current market needs and requirements?
implementability: According to your expertise, is the standard in its current form feasible and can it be implemented cost-effectively? Does the standard allow an implementation with state-of-the-art technologies? Is the standard designed to be future-proof.
Please do not submit new use-cases, features or requirements for the upcoming release.

ASAM OSI 3.8.0

Deadline: Feb 26, 2026

Separate repositories:
This minor release contains a structural change: The core ASAM OSI protobuf definitions and the language-specific bindings and modules have been split into separate repositories, allowing easier maintenance and evolution of language-specific features. The new repositories are as follows

Standard repository: generic interface for the environmental perception of automated driving functions in virtual scenarios - OpenSimulationInterface/open-simulation-interface
ASAM Open Simulation Interface C++ Bindings: OpenSimulationInterface/osi-cpp
ASAM OSI Python Bindings und Utilities: OpenSimulationInterface/osi-python

ASAM OSI checker bundle:

The project group is also releasing a new ASAM OSI checker bundle for use in the ASAM Quality Checker. You can find the new checker bundle here: OpenSimulationInterface/qc-osi-trace: OSI Trace File Checker Bundle for ASAM QC Framework

Additional new features:

Adoption of the ASAM OpenX harmonized vehicle types
Tail light added to vehicle classification/light state
Model_reference attribute added to RoadMarking
Road type added to logical lanes
Improved python bindings via pyi_out option of protoc
Various improvements to OSI rule definitions for new qc-osi-trace checker bundle
Improved specification of BaseMoving reference system
Documentation of Tait-Bryan convention and quaternion formula
