Important results from the project
Chronos 2 has enabled technical progress which will change the way vehicles are tested in the future. What you see in the virtual environment during a test is taking place in the real world, with a few milliseconds delay. All inputs controlling the various robots originate in the virtual environment, weaving virtual and real world into one. This means that the testing is moving from the physical test track to the virtual, simulated track, with the virtual system being in charge of controlling the tests.
Expected long term effects
Active safety functions can now be tested using virtual target injection and a standard interface setup to connect different vehicle brands to one injection platform. This enables safe, repeatable, and efficient testing of active safety. Chronos 2 got the attention of Euro NCAP which is now considering to include virtual injection into future testing protocols. The concept of dynamic trajectories developed in Chronos 2 is being implemented in ISO-22133. The project is leading and giving important feedback to this ISO standard.
Approach and implementation
The project had seven technical work packages, each contributing with building blocks necessary for future implementation of virtual methods in testing of vehicles. A cloud-based C-ITS test system using 4G/5G cellular network was set up, showing that different C-ITS applications can be tested and evaluated. Close integration between the AstaZero test system infrastructure and the C-ITS system was also shown, making it possible to include physical, proxied (e.g. radio-controlled cars) and virtual objects in the test and evaluation of C-ITS applications.
