NI widens commitment to vehicle development
With increasing electronic content, test and measurement system manufacturer National Instruments is becoming increasingly committed in vehicle development. At its NI Days Europe user congress, the company presented new platforms and systems for such applications.

The NI reference architecture for EV testing and NI's investments in workflow integration optimize the HIL test for fast-moving new technologies with rapidly changing requirements. NI's flexible, custom systems help validation teams keep pace with the rapid pace of innovation in the automotive sector by shortening test development time and increasing test coverage.

NI also introduced a Vehicle Radar Test System (VRTS). Radar sensors in the 79 GHz range are among the most widely used vehicle sensors. Although their high bandwidth of 4 GHz enables high resolution and accurate determination of distance and speed, they pose major challenges for the test systems. This is because the high bandwidth generates a corresponding amount of data that needs to be processed. This requires additional processing resources and a larger number of test scenarios as more objects can be detected. NI's VRTS simulation capabilities allow engineers to refine and improve their tests. NI's new VRTS is capable of simulating two objects per angle with a highly repeatable radar cross section (RCS). With the RCS, the simulated obstacle can be used for both validation and production testing. As part of the NI platform, VRTS builds on the long-term flexibility, scalability and cost efficiency of the company's software-defined systems and helps the user to create more accurate test scenarios and achieve shorter test set-up times. In addition, the VRTS is both cost- and space-optimized for large production environments.
