aiMotive Transforms AV Testing by Integrating RoadRunner into aiSim

A leading provider of simulation and AI-based technologies for autonomous vehicle development, aiMotive focuses on scalable, efficient, and deterministic solutions for ADAS and autonomous driving validation. One of its key products, aiSim, is the world’s first ISO26262-certified simulator designed for ADAS and AD verification. It leverages AI-driven content creation, physics-based sensor simulation, and modular integration capabilities to support industry standards such as OpenDRIVE, OpenSCENARIO, FMI, and ASAM OSI.

Challenge

The autonomous vehicle industry depends upon highly accurate and reproducible simulation environments to validate complex systems under real-world conditions. Simulated road networks, intersections, and urban scenarios must not only mimic reality but also scale to support extensive testing and edge case exploration. Achieving this level of precision demands tools that can generate and manage detailed 3D scenes while ensuring compatibility with simulation platforms.

aiSim provides a deterministic, physics-based simulation environment that meets these requirements, to ensure accurate sensor simulation and reproducible testing. However, to fully leverage its capabilities, it requires high-fidelity, simulation-ready environments that seamlessly integrate into its framework without loss of detail or compatibility issues.

Traditional workflows have encountered roadblocks in maintaining interoperability between scene creation tools and simulation engines. This often led to inefficiencies, data inconsistencies, and compromised fidelity during the transfer of complex scene data that created barriers to achieving a unified, efficient simulation process.

Solution

To address this challenge effectively, aiMotive partnered with SciEngineer to integrate RoadRunner with aiSim.

RoadRunner, developed by MathWorks, is a state-of-the-art 3D scene editing tool designed specifically for creating detailed, simulation-ready environments for autonomous vehicle development. Its advanced capabilities allow for the precise modeling of roads, intersections, and complex traffic scenarios, all while adhering to industry standards like OpenDRIVE and OpenSCENARIO. By enabling the creation of realistic environments, RoadRunner plays a critical role in testing and validating ADAS and autonomous driving systems.

This integration creates a unified framework where RoadRunner’s detailed 3D modeling capabilities seamlessly feed into aiSim’s deterministic, physics-based simulation environment. What’s more, aiSim’s modular API architecture enables direct interaction between the two platforms, which eliminates the need for intermediate reformatting or data conversion.

Industry-standard formats such as OpenDRIVE and OpenSCENARIO ensure smooth data compatibility, aligning scene creation and simulation workflows into a cohesive pipeline. This allows for the immediate use of RoadRunner’s outputs in aiSim’s reproducible and physics-accurate testing framework, which is crucial for the validation of ADAS and autonomous systems.

“MathWorks’ solutions are highly intuitive, which makes them easy to integrate into our engineering workflows. They support industry standards, ensuring seamless compatibility, and their user-friendly approach allows our engineers to work efficiently and effectively.”, said Gergely Juhász, SVP of the aiSim department.

Result

The combined capabilities of RoadRunner and aiSim provide a unified approach to simulation, where high-fidelity scene creation and physics-accurate testing coexist in a streamlined process. Engineers can model complex scenarios with precision in RoadRunner and seamlessly validate them in aiSim without losing data fidelity. This workflow eliminates the inefficiencies traditionally associated with scene integration, thus reducing the time required for scenario preparation and accuracy enhancement of simulation outcomes.

The interoperability ensures that environments modeled in RoadRunner maintain their integrity when incorporated into aiSim. This results in deterministic and reproducible testing conditions, in which even the most intricate interactions between vehicles, sensors, and the environment are simulated at a high level of accuracy. The integration also enhances scalability, which allows for the efficient creation and testing of both common scenarios and critical edge cases.

Summary

Challenge: Ensure seamless integration of high-fidelity 3D scene creation and physics-accurate simulation. Interoperability has been a challenge for traditional workflows, often requiring inefficient data conversions and the loss of critical scene details.

Solution: Integrate MathWorks’ RoadRunner into aiSim, which enables engineers to create detailed, simulation-ready environments that directly feed into aiSim’s deterministic testing framework without losing data fidelity.

Results:  

• High-fidelity 3D scenes from RoadRunner are seamlessly integrated into aiSim.

• Deterministic, physics-accurate testing ensures reproducible validation of ADAS and autonomous driving systems.

• Streamlined workflows reduce scenario preparation time and enhance scalability for large-scale simulations.
