The VIRES VTD software, for example, is used to test Advanced Driver Assistance Systems (ADAS) and autonomous driving systems by simulating scenarios so manufacturers and technology companies can test vehicles and their component systems. VTD incorporates open interfaces for run-time data and simulation control making it modular and scalable. Customization tools include SDKs, templates for sensor simulation (object-list based and physics based), dynamics simulation and image generation.

Users of VTD may customize the software on various levels. But virtual testing makes it possible to replicate the exact same scenarios to validate the system’s safe response. No two real-world road conditions or hazards are ever precisely the same.

What could be more realistic than driving through a tunnel in the rain to see how the automated diving system copes? The problem – ironically – is that it’s impossible to then replicate those same conditions (weather, traffic, etc.) a week later to test if the updated system gives the desired response. Nevertheless, road tests can help find outlier scenarios. There will always be scenarios such as road markings that reflect in a tunnel or a traffic light failure that vehicles never see during road tests but which could leave an autonomous system blind-sided in the real world. If handled through road testing, regional differences would require carefully planned test campaigns in every export country, quickly rendering the approach unfeasible. To ensure vehicles can respond to all known circumstances, regional differences must be accounted for.

Not so hard perhaps – but what happens when the same traffic light signals are interpreted differently in another country? In the U.S., you can make a right turn when the lights are red, but in Italy drivers would expect an additional light to filter traffic turning right. All logic data is exported compliant to the OpenDRIVE format.Īn autonomous driving system trained to recognise a road sign in English would need to be trained so it could recognise the Japanese equivalent. Various import and export formats as well as large libraries of 3D models and country specific signs/signals accelerate the creation process. Virtual worlds can be designed from scratch or compiled from existing database tiles. The Road Network Editor (ROD) lets developers design roads having an unlimited number of lanes, complex intersections, comprehensive signs and signalling. For example, if you train a system on road signs in Europe and export the vehicle to the U.S., you must be sure it can understand the different national traffic laws. Incidents such as a speed sign being altered with duct tape form what autonomous carmakers call “edge cases,” rare scenarios that autonomous vehicles are unlikely to encounter in road testing but that may nonetheless happen in reality.Īutonomous systems may not understand situations outside the context of their training data, so edge cases that humans can readily handle may fool an autonomous driving system.

The answer is complex but lies partly in the litany of real-world events which simply cannot be covered with real-world road testing. So why do such serious safety defects continue to go undetected during design, engineering and pre-production? More troubling, it is also likely that many other latent defects afflicting autonomous vehicle systems lie waiting to be exposed. Such a fault could affect the 40 million vehicles using similar image-recognition systems. It is used in SiL, DiL, ViL and HiL applications and may also be operated as a co-simulation with third-party packages. It can generate 3D content, simulate complex traffic scenarios, and simulate sensors.

It is used for the development of ADAS and automated driving systems as well as the core for training simulators. This view is from VTD, for virtual test drive. Now, the term is more likely to be associated with tools that create problems for autonomous vehicles to solve. Virtual worlds were once equated with computer simulations involving avatars and multiplayer video games. In a demonstration, McAfee was able to fool a Tesla car into accelerating to 85 mph in a 35 mph zone using a piece of duct tape. In February, McAfee exposed the alarming gap between the road test and real-world performance of autonomous vehicle sensors. Why unsafe autonomous vehicle systems are passing undetected during development.
