In order to mitigate risks from road tests for autonomous-driving vehicles, reduce costs and accelerate development, a virtual reality (VR)-based test platform for autonomous-driving vehicles was built combined with the AirSim system and the UE4 engine by establishing a model library which contains the vehicle dynamics model, sensor models and traffic environment model. The controller-in-the-loop simulation method was implemented to complete the simulation test for autonomous vehicles under different driving conditions and the simulation results were used to optimise the autonomous-driving control system. The actual autonomous driving road test can now be done in an immersive VR simulation environment where autonomous-driving road-testing is done safely and cost-effectively. This plays a significant role in the future development of autonomous-driving vehicles.
