An HD map is a basis for reliable perception in an AD vehicle. Using an HD map requires a precise and reliable position. Localization systems based on few sources like GNSS or simplified models don’t achieve the required precision in all conditions. To provide a robust and reliable position considering the requirements of perception and planning modules, we developed a localization system combining modules for relative and absolute localization. Both modules have been extended to 3D for increased robustness and urban applications. After a quick insight into relative localization, the focal point of the presentation is the absolute localization module, estimating the vehicle position in a map. Examples of using ARUCO markers and a radar grid as landmarks are shown. For extreme scenarios – like a multilevel parking garage – both localization modules have been extended to 3D. Results of closed loop validation in real world scenarios are shown to prove that the system is providing a precise and reliable position also in challenging situations.
Dr. Ralph Grewe started his career at Continental in 2011 with a PhD position in the field of environment modeling at the Advanced Engineering of Systems & Technology, where he took over the position as group leader for perception and environment model in 2016. In 2018 he became the Domain Owner for the CEM and Localization Domains in the Program Automated Driving. Since January 2022, he is the Product Manager of Perception at the Innovation Line Driverless of the Systems & Software Business at Autonomous Mobility.
