(ASAM OpenODD is not yet a finalized standard but a concept, which serves as basis for a future standard. The proposal workshop to prepare the development took place on Mar 14, 2022. Review)
ASAM OpenODD (Operational Design Domain) is still a very young standardization initiative within the ASAM Simulation domain. The aim is to provide a format that is capable of representing a defined Operational Design Domain for connected automated vehicles (CAV).
An Operational Design Domain Definition (ODD) should be valid throughout the entire operating life of a vehicle and is part of its safety and operational concept. The ODD is used for the functional specification of connected automated vehicles. It specifies what environment parameters (static and dynamic) the CAV must be able to manage. They include all types of traffic participants, the weather conditions, the infrastructure, the location, the time of day and everything else that can have an impact on the driving situation.
To give an example: Looking at the picture below, an ODD would define the following parameters as suitable for the vehicle:
• Paved road
• Right hand traffic
• Country road
• No visibility limitation due to weather or time of day
• Expect all possible traffic participants
• Expect animals
But there will be many more attributes in the ODD to describe this road and the environmental conditions.
The goal of the ASAM OpenODD concept project was to create a machine-interpretable format to represent the ODD specification. With this format an ODD description becomes exchangeable, comparable and processable. This new format will enable for example the following use case:
The ODD must be represented so it can easily be used for simulation and other machine processed environments. The content of ASAM OpenODD will be derived from an abstract „Vehicle ODD“, that provides the information in a usable manner. For the purpose of using an abstract vehicle ODD description (represented in ASAM OpenODD) for simulations and post-processing the format must fulfil the following requirements:
During the concept project, the following aspects were addressed in particular:
The ASAM OpenODD standardization initiative takes into account and aims to complement the activities of BSI (BSI PAS 1883 provides a taxonomy for ODD) and ISO (ISO 34503 uses the taxonomy to provide a high-level definition format for ODD). All three projects are in close contact to avoid contradictions.
