Maximize Test Coverage with Your ADAS/AD Replay Test System

Validating perception algorithms on ADAS ECUs is key to ensuring the safety and reliability of ADAS and AD functions in the vehicle. The industry must efficiently scale test coverage by implementing methodologies such as replay and HIL, which moves testing from the road to the lab. Replay test requires replicating the driving scenarios by injecting real-world road data exactly as it was acquired in the vehicle to test the complex algorithms and ensure the safe operation of ADAS and AD functions. The replay system must:

 

  • ​Feed the system with external data in the same way as it would be done with the vehicle during actual test drives
  • Interface with the ADAS controller through multiple I/O and automotive bus signals with tight control over timing and data synchronization
  • Maintain adaptability for future I/O and test requirements as systems continue to add more cameras, radar, lidar, and other ADAS sensor types
  • Increase test coverage reliability and repeatability through direct injection techniques to insert faults, frame delays, and more into the sensor bitstream

NI Replay and HIL System AD

 

  • Replay and HIL AD Environment Server Deployment software for data throughput, timing and synchronization, direct interface with ECU, full customization, data repositories, and simulation interfaces.
  • PXI technology provides hardware and software faulting capabilities—down to nanosecond synchronization and timing control for a reliable execution of test cases.
  • Modular hardware generates signals to emulate ADAS sensors,    vehicle bus traffic, and general purpose I/O to test sensor fusion on the ADAS controller.
  • Open software-centric approach that enables interfaces and sourcing data from IT infrastructure and cloud service providers like Microsoft Azure, AWS, Seagate, and more.
  • A unified test system architecture to move back and forth between data replay and HIL test with the same system and single toolchain for data record. 

Solution Advantages

  • Ensure synchronous data feed from either your NI record systems or other timestamped recording files.

  • Future-proof your system with hardware and software customization, flexibility, and third-party openness.

  • Move back and forth between data replay and HIL test through a unified test system architecture within the same system and a single platform for data record.

  • Maximize test coverage by running more test cases and scenarios in the lab.

  • Develop faster by leveraging work across design and validation through NI’s toolchain to perform reliable test at each stage.

  • Keep requirements from outgrowing test capability with NI’s range of I/O for cameras, radar, V2X, lidar and GNSS, and buses.
