SAE World Congress Experience (WCX) is the largest technical mobility event developed by the industry, for the industry. The only place where the entire global mobility community comes together to exchange ideas and deal with the challenges of today. Over three days, thousands of engineers, executives, suppliers, academics, and R&D professionals will attend WCX for the high-level technical sessions, lively roundtables, and a wide range of networking event.
Come see dSPACE's Jacob Perrin and Andreas Himmler speak at SAE WCX.
Jacob Perrin - An Analysis of Data Curation Techniques Throughout the Perception Development Pipeline
April 18 – Room 252 B – 10:30AM
The development of perception functions for tomorrow's automated vehicles is driven by enormous amounts of data: often exceeding a gigabyte per second and reaching into the terabytes per hour. Typically, this data is gathered by a fleet of dozens of mule vehicles which multiply the data generated into the hundreds of petabytes per year. Traditional methods for fueling the data-driven development cycle would record every bit of every second of a data logging drive on solid-state drives located on a PC in the vehicle. This data must then be offloaded from these drives using some upload station which then pushes to the data lake after arriving back at the garage.
In this discussion, Perrin will speak on different techniques for curating the logged data to reduce the costly overhead of data storage. The reduction of logged data has the effect of not only curtailing storage costs, but to minimizing latency for data availability and maximizing possible campaign drive time. Advanced techniques considered include:
- The real-time analysis of sensor and bus data.
- The application of artificial intelligence (e.g., for similarity-based image discovery and dynamic scene content).
- Using function prototyping to inform data collection efforts.
Andreas Himmler - Validation of 60GHz in-vehicle radars for child presence and occupant safety
April 20 – Room 250 A – 10:00AM
In this discussion, Himmler will speak on current challenges of validating and testing 60GHz in-cabin monitoring imaging radars, as well as presenting an Over-The-Air (OTA) solution for precise and repeatable measurements. As automobiles approach SAE Level 3 and above, occupancy monitoring systems (OMS) are needed to monitor the safety of both driver and passengers. Another reason for the increased trend in OMS is to detect children or pets left in the backseat of the vehicle. The current trend for OMS systems is utilizing 60GHz high bandwidth imaging radars. These radars can detect vital signs such as breathing rate and heartbeat.
However, testing these radars with humans are impractical, costly, and difficult to repeat. One solution is utilizing an OTA radar target simulator that allows for emulation of vital sign such as heartbeat and breathing rate with micro-doppler generation techniques. The target simulator supports up to 5GHz of instantaneous bandwidth and can simulate short distances of less than 1 meter, as required by the individual in-cabin application. The target simulator allows for repeatable measurements across all development phases such as R&D, validation, and end-of-line production.
