Sensor Fusion HIL with Scene Generation

Integrate scene generation tools with hardware I/O to play back simulated scenarios for validating the sensor fusion and decision-making algorithms on ADAS controllers. Scene generation increases test coverage because you can create scenarios that meet specific test requirements rather than relying on road tests or previously recorded data.

Application Requirements:

• Integrate hardware I/O with scene generation tools like IPG CarMaker, VIRES VTD, or TASS PreScan
• Synchronously generate I/O signals to interface with the ADAS controller; with tight control over timing
• You can test faults like frame delays or phase coherency
• Maintain flexibility for future I/O requirements as systems continue to add more cameras, radar, and I/O types like lidar

NI Solution:

• Integrate with a wide variety of third-party scene generation tools using VeriStand real-time test software, so you can choose the tool that works best for you
• Use PXI modular hardware to generate OTA radar signals, camera signals, vehicle bus traffic, and general-purpose I/O; it also features hardware and software faulting capabilities and nanosecond synchronization and timing control
• Implement test sequencing with TestStand automated test software or Python scripting to automate test vectors and increase test coverage in shortened test schedules

The NI Advantage:

• Achieve the greatest control over your test system and maximize your test coverage using the openness of the NI toolchain
• Change camera interfaces, inject bitstream faults, test radar sensors with real over-the-air (OTA) reflections, or add new sensor types without significant costs or hardware changes
• Future-proof your system with a modular, software-defined platform like PXI combined with VeriStand; you can simply add an I/O module to the system as your requirements change
