The Role of High Fidelity Simulation in ADS Validation

Once control logic and planning policies are verified at the object level, the next critical step is to ensure your Automated Driving System (ADS) performs reliably in sensor-rich, perception-driven environments. High Fidelity simulation enables exactly that—bringing together object-level data and raw sensor signals to evaluate how the ADS interprets, understands, and reacts to complex, dynamic scenes.

This phase is essential for validating perception modules, refining planning behavior, and ensuring system-wide readiness under realistic conditions.

 

Executing High Fidelity Test Suites in ReplicaR

Powered by the ReplicaR execution engine, High Fidelity simulations combine the spatial accuracy of OpenDRIVE maps, structured scenarios from OpenSCENARIO, and detailed sensor modeling through Open Simulation Interface (OSI). This comprehensive setup replicates real-world perception inputs and ensures robust, integrated ADS testing.

Key capabilities include:

  • Sensor Simulation: Raw data from simulated cameras, LiDAR, radar, and other perception systems is generated and fed into the SuT.
  • Full-Stack Evaluation: Assess the complete ADS pipeline—from sensing to actuation—under controlled, reproducible conditions.
  • Real-World Realism: Traffic participants, infrastructure, and environmental features behave in accordance with high-fidelity standards.

 

Why It Matters: In-Depth Policy and Perception Validation

High Fidelity execution bridges the gap between virtual and physical testing, enabling:

  • Validation of sensor fusion and object detection
  • Verification of end-to-end decision-making
  • Exposure to corner cases not easily testable in real life

Whether testing obstacle detection, response to occlusions, or interaction with vulnerable road users, this mode offers full-stack confidence in your system’s capabilities.

 

Conclusion

High Fidelity simulation in ReplicaR is your gateway to realistic, end-to-end ADS validation—ensuring not only that your system can drive, but that it can see, understand, and decide under the most demanding conditions.
