High-​Bandwidth In-​Vehicle Data Logging for ADAS and AD

Advanced driver-​assistance system (ADAS) test engineers record sensor and ground truth data during road testing to verify sensor capabilities and train ADAS and autonomous vehicle (AV) algorithms. Autonomous driving (AD) software demands multiple high-​bandwidth sensors, driving exponential data volume and movement growth. To cost-​effectively keep up with technology, today’s data-​recording solutions must be simultaneously high-​performance, forward-​thinking, and adaptable.

 

  • Synchronization—​Provide submicrosecond-​level accuracy for sensor and vehicle network interfaces. 
  • Changing and Evolving Requirements—​Adapt to evolving vehicle technology for current and future regulatory requirements.
  • Data Volume—​Manage data creation in GB/​s while storing hundreds of TB per day and vehicle.
  • Data Quality and Cost—​Precisely measure I/​O, lossless data handling, and data reduction at the beginning of the data life cycle.
  • Integrated System—​Eliminate multiple disparate sensor recording solutions to avoid installation complexity and decrease the risk of failure.

NI Data Record System AD

  • Leverage PXI Express—​the open industry standard​—​for high-​throughput data streaming, tight synchronization through an integrated 100 MHz clock, and high-​performance computing.
  • Use native GMSL and FPD-​Link camera interfaces to log vehicle sensor data without additional converters directly into the NI PXI system.
  • Choose an automotive network (Automotive Ethernet, FlexRay, CAN, or LIN) and Ethernet interfaces from NI’s catalog and augment the open system with third-​party products.
  • Select from proven IT storage options and combine PXI in-​chassis data recording devices and external RAID systems of up to 200+ TB.
  • Use Data Record AD, NI’s high-​performance application software, for data movement and synchronization, including a diagnostics UI and customization through APIs and plug-​ins.

Solution Advantages

“The Assisted and Automated Driving Verification and Validation (V&V) department at JLR works closely together with NI to develop synergies between V&V methods and tools. The possibility to use the same data as well as common hardware and software platforms for ADAS data logging, SIL, HIL, and VIL increases our V&V testing to be more robust and efficient and deliver better quality. ​We adjust tools to our process, not the opposite!”
