TECH INSIDER What were the biggest challenges? Fast development cycles, frequent software changes and need for adjustments, and ensuring global synchronization across all brands. How much virtual analysis have you done? Software pre-qualification via simulation and the subsequent data evaluation via simulation have been an integral part of the development process. “Data recording in a vehicle, including raw sensor data, requires 25GB per trigger/per minute” Stephan Reichle, team leader for testing and application of driver assistance systems, Daimler Truck How much data might be harvested in a day? Data recording in a vehicle, including raw sensor data, requires 25GB per trigger/ per minute. This means that very large amounts of data can be generated per day. ABOVE: Stephan Reichle, team leader for testing and application of driver assistance systems BELOW: Daimler is currently testing its new 270° sensor fusion technology, which enables almost complete all-round visibility, increasing protection for the most vulnerable road users prohibit the elimination of the driver during autonomous driving. Other federal states allow this or have not commented.” The company underlined that Torc Robotics is assessing L4 autonomous trucks with enhanced capabilities on public roads in Virginia, New Mexico, Texas and Arizona. The situation in Europe is encouraging too, with various recent developments strengthening the framework. “In 2022 the EU adopted a comprehensive legal framework for the type approval of autonomous vehicles. EU regulations stipulate What major lessons have you learned? How to combine automotive ethernet with new measurement and evaluation technology, as well as the handling of large amounts of data. that an autonomous driving system can take over the entire dynamic driving task within a pre-approved operating area. However, the autonomous driving system must be monitored by a technical supervisor who can deactivate the function or release alternative driving maneuvers from a control center in the event of difficulties.” Daimler Truck noted that when it comes to testing, the regulations are not harmonized within the EU, although there are national regulations. “The testing of AVs is permitted in some member states such as Germany. In our opinion, there should be a harmonized regulation for the testing of autonomous driving functions within the EU.” Once introduction in the USA has been achieved in 2027, Daimler Truck will be able to roll out its L4 technology elsewhere with a more manageable development workload. “Europe could then be one of the next regions we enter. Despite the positive regulatory development, we do not expect this to happen before 2030.” 16 MARCH 2024 www.AutomotiveTestingTechnologyInternational.com
