THE TEST SYSTEM ENABLES AUTOMOTIVE SYSTEM developers to record different real-world signals and then replay them in development labs, to shorten the time taken to validate new hardware or software. This lab-based approach complements the conventional field testing using fleets of vehicles. It also helps to minimize the development and validation time for new features for vehicle-to-vehicle (V2V) communication technology. V2V communications could mitigate many traffic collisions and reduce traffic congestion by sending and receiving basic safety information such as location, speed and direction of travel between vehicles approaching each other.

This automotive test system is an integrated custom solution that provides radio frequency (RF) recordings for global navigation satellite systems (GNSS)—GPS, Glonass, Galileo, Beidou, and QZSS— and vehicle CAN data. The system can also record up to four video streams, audio and other high-speed sensor data to provide a more complete record of the route. The recorded data is time-stamped and can then be replayed to help engineering teams verify new design work all over the world without leaving the lab.

“By providing vehicle manufacturers with a wide range of test capabilities from the wireless, positioning, and computer networking industries that complement drive testing, we can help the auto industry adopt connected car technology with more confidence,” said Pete Nicholson, general manager of Spirent’s Automotive Business Unit. “Our system allows automotive OEMs to develop and validate new products more quickly, by making tests repeatable using real-world signals in a lab environment.”
