ASAM OSI: Standardising Automotive Simulation

Understanding the ASAM OSI

The automotive industry is rapidly evolving, driven by advancements in autonomous driving and vehicle electrification. To keep pace with this rapid change, efficient and accurate simulation tools are essential. The ASAM e.V. Open Simulation Interface (OSI) is emerging as a key standard in this domain, enabling seamless integration and interoperability between diverse simulation tools and frameworks. OSI addresses the emerging standard ISO 23150 for a real sensors’ standardized communication interface. OSI defines generic interfaces to ensure the modularity, integrability, and interchangeability of the individual components.

What is ASAM OSI?

ASAM OSI is a standardized interface that facilitates communication between different simulation components, such as:

• Sensor models: Simulating the behavior of various sensors like cameras, radars, and LiDARs.
• Vehicle dynamics models: Modeling the physical behavior of vehicles, including their motion and handling characteristics.
• Environmental models: Creating realistic virtual environments, including roads, traffic, and weather conditions.

Key Benefits of ASAM OSI:

1. Interoperability: ASAM OSI promotes seamless integration between different simulation tools and frameworks, regardless of their origin or vendor. This reduces development time and effort.
2. Efficiency: By providing a standardized interface, ASAM OSI streamlines the process of setting up and executing complex simulations.
3. Flexibility: The modular design of ASAM OSI allows for easy customization and extension to accommodate specific simulation needs.
4. Accelerated Innovation: By enabling rapid prototyping and testing, ASAM OSI accelerates the development of advanced automotive technologies.

How ASAM OSI Works

ASAM OSI defines a set of data structures and protocols for exchanging information between simulation components. These components can be implemented in various programming languages and run on different platforms.

Core Components of ASAM OSI:

• Ground Truth Interface: Provides accurate information about the simulated environment, including object positions, velocities, and other relevant data.
• Sensor Data Interface: Delivers simulated sensor data, such as point clouds, image frames, and radar measurements.
• Traffic Participant Interface: Enables interaction with virtual traffic participants, including vehicles and pedestrians.
• Scenario Definition Interface: Defines and manages simulation scenarios, including initial conditions, traffic patterns, and event triggers.

The Future of Automotive Simulation

ASAM OSI is poised to play a pivotal role in the future of automotive simulation. As the industry continues to embrace autonomous driving and advanced driver-assistance systems, the need for robust and efficient simulation tools will only grow. By adopting ASAM OSI, automotive engineers and researchers can accelerate innovation and bring safer, more intelligent vehicles to market.
