A mobile data handling concept developed by Germany-based specialist ViGEM should, according to the company, make 24/7 utilization of test fleets for ADAS and AD validation driving feasible.
The system is based on the fast, uncomplicated exchange and shipment of robust removable data storage devices independent from the vehicle under test. As ViGEM’s CEO, Markus Trauth, explained, “Thanks to the robustness of our removable data storages and the mobile data handling concept, our customers are able to reduce the downtime of their vehicles to a minimum compared to other data transfer methods. Test fleets can thus be utilized almost 24/7, which holds significant potential for cost savings for ViGEM customers.”
In practice this means that large amounts of test data can be made quickly available to manufacturers’ development departments while testing is still ongoing. Working in cooperation with OEMs, ViGEM says it has developed a suite of integrated hardware and software components (Car Communication Analyzer – CCA) for the efficient validation of advanced driving functions. By ensuring seamless interaction between elements such as dataloggers, robust storage media and fast copy stations, featuring transfer rates of up to 50Gb/s, maximum data reliability and security are ensured.
For example, the SSDs installed in its CCA 9010 solution, with up to 64TB storage capacity and data rates of up to 25Gb/s, can continuously record raw data for approximately eight hours. Their shock- and vibration-tested metal housings can withstand even the highest mechanical stresses and allow operating temperatures from -20°C to +65°C, meaning they can be removed from vehicles and transported safe in the knowledge the data they contain is secure.
