FlexLogger helps validate new and rapidly evolving technologies to keep pace with vehicle electrification and Advanced Driver Assistance Systems (ADAS), without programming, the company said. FlexLogger provides intuitive workflows and integrated data management to help automotive test departments quickly capture accurate, well-documented data to verify system functionality in real-world conditions and comply with strict government regulations.

Technology innovations in the areas of active safety, electrification and vehicle-to-everything (V2X) communication are disrupting how the automotive industry designs, tests and produces vehicles, noted NI. It said rapidly-evolving components and systems including sensor fusion, high-capacity batteries and Deep Learning demand higher volume of testing with accurate, traceable results to exceed safety-critical expectations for quality and reliability. These trends are intensifying the challenges to automotive test departments to build increasingly complex, mixed-measurement test systems under compressed timelines, while managing the explosive growth of collected data, NI added.

FlexLogger can be used by engineers to help simplify test configurations and extract key insights with sensor-specific workflows to acquire and log synchronised, mixed measurements, without any programming, explained NI. Analogue sensors, digital pulse frequencies, CAN signals and calculated channels that are all logged to the universal Technical Data Management Streaming (TDMS) file format can be integrated quickly. This leads to the capability of data being correlated and analysed to accurately characterise an entire system. These capabilities also address similar challenges faced by test departments in other industries including heavy equipment, aerospace, appliances and academic research, the company said.

NI said that these configuration-based workflows are the cornerstone that now empowers technicians to streamline test development, integrate new measurements and manage data using its flexible software platform and modular hardware. FlexLogger automatically logs descriptive metadata about the test configuration, including sensor and hardware acquisition settings for easier traceability. Test departments can improve access to data and effectively communicate results to the organisation using DIAdem data management software to find, analyse and report on FlexLogger data, it added.


Since 1976, National Instruments has equipped engineers and scientists with tools that accelerate productivity, innovation and discovery. NI’s graphical system design approach to engineering provides an integrated software and hardware platform that speeds the development of any system needing measurement and control. The company’s long-term vision and focus on improving society through its technology supports the success of its customers, employees, suppliers and shareholders.
