Visitors can experience Xylon’s Quattro datalogger and HIL system at the expo. The system boasts 128Gbps of datalogging and playback bandwidth, 128TB of internal data storage, industry-leading automotive interfacing, open software architecture and HIL capabilities.

Quattro plays back automotive sensory data in its original form and connects directly to DUTs through native automotive interfaces. Playback data is electrically and logically formatted to fully correspond with the requirements of the internal buses of an operational vehicle driving along the road. The system replicates the test vehicle’s multicamera video system and in-vehicle data buses on a developer’s desk.

The equipment can also inject synthetically generated automotive sensory data. In cooperation with prominent providers of software simulation platforms, Xylon has developed software plug-ins that fetch simulated data and record it in MDF4 data formats, which are suitable for HIL data injection.

Besides easy road harvesting of unaltered raw data from test vehicles, Quattro enables realistic playback of recorded sessions. The playback is based on recorded timestamps that enable the logger to restore exact timings and signal relations between multichannel sensory data in real time. This feature greatly eases R&D and testing in lab environments. For example, a lab tuning of the computer vision system, fed with the specific driving situation, can be looped as long as needed without requiring additional test drives.
