As advanced driver assistance systems (ADAS) continuously evolve and develop, the borders between simulation and real-world testing are slowly disappearing. The Budapest University of Technology and Economics and the ZalaZONE R&I Team are working together to develop new testing method, where the virtually created scenarios can be transferred in real-time into an actual physical scenario test actuating real-world test equipment (like pedestrian target, guided soft target, steering robot) on the ZalaZONE Automotive Proving Ground.
The main steps are the followings:
- To create a simulation environment with high accuracy, also called digital-twin. ZalaZONE Proving Ground modules are laser scanned to get a PointCloud for virtual environment.
- In this virtual environment, we can build roads with centimeter accuracy and export it as OpenDRIVE file.
- In VTD Vires we can use the OpenDRIVE to build scenarios and check these by Simulation.
- After building the scenario, it can be exported to an OpenSCENARIO file, which defines the description of dynamic elements and actions placed on the road network.
- Then OpenSCENARIO file must be converted to readable file for ABDynamics tools. To accomplish this, we are developing a converter in MATLAB software environment that converts files into a structure that can be processed by AB Dynamics test tools software.
The whole process of pre-building the scenario in a simulation and converting it with a few clicks using a Converter greatly speeds up the compilation of real tests.
