VI-grade and Aidoptation Build Virtual Testbed for High-Speed Autonomous Driving

Validating autonomous driving systems at highway velocities is one of the toughest challenges in the field, because real-world testing at those speeds carries serious risk. Simulation specialist VI-grade has teamed up with Belgian developer Aidoptation to tackle exactly that problem, using a blend of virtual testing and controlled proving-ground runs to certify Level 3 and Level 4 motorway autonomy.

The collaboration centers on Aidoptation’s EdgeDrive, an advanced driver assistance system designed for Level 4 motorway operation. Under the arrangement, EdgeDrive will be integrated with VI-grade’s VI-WorldSim and VI-CarRealTime platforms. The two partners also plan to construct a digital replica of Aidoptation’s test vehicle, built from recorded track data, so that simulated and real-world results stay closely aligned.

The joint effort places particular emphasis on edge cases occurring between 120 and 130 km/h, where vehicle dynamics, stability and tyre grip become increasingly difficult to control. A dedicated scenario library covering that speed band will combine VI-grade’s automated scenario generation with Aidoptation’s pass/fail criteria, with the goal of establishing a framework for determining which situations can be cleared through simulation alone and which still require physical track time.

Rodrigo Senofieni, Head of Engineering at Aidoptation, framed the work around model fidelity: getting both a vehicle dynamics model that realistically reproduces behaviour at the limit of grip and a world model capable of placing that behaviour in a convincing environment allows a safety-critical manoeuvre to be validated before the vehicle ever performs it. He noted that because EdgeDrive is deterministic, simulation and track results converge, cutting the development timeline for each new manoeuvre from months down to weeks.
