Mobile data handling allows 24/7 utilization of test vehicle fleets

Vigem says their new mobile data handling concept allows the efficient utilization of test vehicle fleets used in the validation of automated driving functions (ADAS) and autonomous driving.


"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."

Said Markus Trauth, Managing Director of ViGEM


The company says that even the largest data volumes are available to the development departments for data analyses within a very short time. The Big Data recorded during the test drives comprises environmental, traffic and communication data from high-resolution cameras, various radar and lidar sensors, and automotive Ethernet interfaces. They can now be used in innovative mobility projects or for the development of artificial intelligence (AI).

In close coordination with OEMs and suppliers of the automotive industry, ViGEM develops integrated hardware and software components (Car Communication Analyzer - CCA) to validate advanced driving functions efficiently. The optimal interaction of high-performance Big Data loggers, robust storage media and fast copy stations, featuring transfer rates of up to 50 Gbit/s, ensures maximum data reliability and security.

For example, the SSDs installed in the high-end CCA 9010 solution with up to 64 TB storage capacity and data rates of up to 25 Gbit/s can continuously record raw data for approximately eight hours. They are thus currently among the most powerful mobile storage media devices on the market. Their shock- and vibration-tested metal housings can withstand even the highest mechanical stresses and allow operating temperatures from -20° to +65° Celsius.


When developing advanced concepts, like Connected Car, V2X or Autonomous Driving, it is first necessary to record, store and analyze enormous amounts of data. To record this data, numerous test vehicle fleets are in operation worldwide and over many thousands of kilometres. In addition to the mobile storage of these ever-increasing volumes of raw data, the fast readout and intelligent data analysis pose new challenges to the industry.

With the combination of high-performance products for mobile Big Data logging and a smart mobile data handling concept, ViGEM supports the automotive industry worldwide in the efficient validation of automated driving functions and autonomous driving. The possible 24/7 utilization of test vehicle fleets becomes an attractive (cost-reducing) option during the development of safety functions for future mobility.
