Networked DAQ system for lane keeping assistant tests

Advanced Driver Assistance Systems, also known as ADAS, are nowadays implemented in almost every new car. Those systems use integrated sensors and cameras as well as artificial intelligence to increase the car and road safety. One essential new part of ADAS is the lane keeping assistant. His job is to ensure that a vehicle doesn’t leave the designated traffic lane. The aim of DEWETRON’s test and measurement systems is to make the world more predictable, efficient, and safe. One contribution to reach that goal is to provide networked data acquisition systems for lane keeping assistant tests.

Challenges during a lane keeping assistant test
The development, test and verification of lane keeping assistants is one of the most complex challenges when developing an Advanced Driver Assistant System. Parameters like the absolute position of the vehicle under test (VUT) and the vehicle bus data need to be controlled. Furthermore, the distance of the VUT to the lane delimitations and adjacent vehicles need to be determined highly accurate and updated online.
The user faces the following challenges:
- Synchronous acquisition and storage of different data streams in multiple VUTs
- Central control unit for quick and remote system setup
- Online data transmission to one central system
- Safe operation even over long distances
- Absolute position and movement determination of every VUT
- Online distance calculation between all VUTs
- Online distance calculation to lane delimitations
- Synchronous video recording for visual reference
- Comparison of vehicle bus data and measurement data
