Future-Proof ADAS HIL Test for Maximum Reliability
To achieve required reliability and safety levels of advanced driver assistance systems (ADAS) and Autonomous Driving (AD), the industry needs to scale test coverage capacity to execute an ever-expanding range of scenario-based Hardware-in-the-Loop (HIL) tests from prerecorded data acquired from test drives or virtual data from high-fidelity environmental simulation software. Testing infinite cases and scenarios requires HIL test to increase simulation and lab tests. The HIL system must be capable of:
- Stimulating the perception systems with advanced processing and data manipulation techniques to convince the ECU that it is performing a real-world scenario.
- Integrating hardware I/O with environmental simulation tools like IPG CarMaker, Ansys VRXPERIENCE, VIRES VTD, Simcenter Prescan by Siemens, and monoDrive.
- Interfacing with the ADAS controller through multiple I/O and automotive bus signals with tight control over timing and data synchronization.
- Maintaining adaptability for future I/O and test requirements as systems continue to add more cameras, radar, lidar, and other ADAS sensor types.
- Increasing 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 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 reliable execution of test cases.
- Modular hardware generates signals to emulate radar objects, camera interfaces, vehicle bus traffic, and general purpose I/O to test sensor fusion on the ADAS controller.
- Open software-centric approach to interface with a variety of simulators such as monoDrive, AVxcelerate, CarMaker, and IT infrastructure and cloud service providers.
- A unified test system architecture to move back and forth between HIL and data replay test with the same system and single toolchain for data record, SIL, and test coverage.
Solution Advantages
-
Develop faster by leveraging work across design and validation through NI’s toolchain to perform reliable test at each stage.
-
Integrate simulation from modeling software and inject signals from different sources for maximum interoperability of test tools.
-
Maximize test coverage by running more test cases and scenarios in lab and simulation to decide which tests must be performed on the road.
-
Keep requirements from outgrowing test capability with NI’s range of I/O for cameras, buses, radar, and other ADAS sensors.
-
Enable moving back and forth between data replay and HIL test with a unified test system architecture.

“We were able to efficiently integrate products from multiple vendors, reuse existing components, and design the flexibility into the system such that we can prepare for future needs. The ease of setting up the whole system enabled us to deliver world-class quality on time and at the right cost with limited resources.”
