Data replay and HIL testing drive ADAS system innovation, says NI 

Test efficiency is increased by unifying data replay and hardware in the loop (HIL) testing, said NI as it introduced its Replay and HIL AD system for advanced driver assistance systems (ADAS) and autonomous driving (AD). 

The NI Replay and HIL AD system can aggregate and inject real-world road test data or simulation scenarios to validate the perception, planning and control algorithms running on ADAS electronic control units (ECUs). By providing a unified toolchain, common hardware configurations and test automation infrastructure across the ADAS workflow, companies can reduce capital equipment costs, improve test coverage and efficiency and shorten the time to market, claimed NI. The approach ensures full validation test coverage for ADAS / AD functions, making existing data more usable throughout the entire product lifecycle.

The system allows customers in autonomous vehicle (AV) testing to quickly and efficiently test the complex algorithms and AI-based software embedded within today’s AVs,” said Drita Roggenbuck, senior vice president of NI’s transportation business unit. 

These customers include ZF Mobility Solutions, a subsidiary of ZF Group, one of the world’s biggest automotive Tier 1 suppliers, develops test systems, tailored to the specific demands of verification and validation of complex autonomous transport systems and ADAS functions.

“AD and ADAS require the combination of different test methodologies which is challenging but essential to provide driver and passenger safety and ultimately for AVs to become a reality. With NI solutions, we can build up systems and move one step closer to a comprehensive test strategy consisting of both real-world and virtual test efforts,” said Dr. Thomas Herpel, senior manager at ZF Mobility Solutions.
