Autonomous vehicles rely on HD maps for their operation, but offline HD maps eventually become outdated. For this reason, online HD map construction methods use live sensor data to infer map information instead. Research on real map changes shows that oftentimes entire parts of an HD map remain unch…
Scalable multi-agent driving simulation requires behavior models that are both realistic and computationally efficient. We address this by optimizing the behavior model that controls individual traffic participants. To improve efficiency, we adopt an instance-centric scene representation, where each…

Autonomous vehicles rely on detailed and accurate environmental information to operate safely. High definition (HD) maps offer a promising solution, but their high maintenance cost poses a significant barrier to scalable deployment. This challenge is addressed by online HD map construction methods,…
Classifying intentions of other traffic agents is an essential task for intelligent transportation systems. To simplify this task, vehicles are equipped with various illumination systems, including turn indicators, emergency lights, rear lights, and brake lights. We extend the Waymo open perception…
Accurate intrinsic calibration is essential for camera-based 3D perception, yet, it typically requires targets of well-known geometry. Here, we propose a camera self-calibration approach that infers camera intrinsics during application, from monocular videos in the wild. We propose to explicitly mod…
While automated research vehicles are already populating the roads, their commercial availability at scale is still to come. Presumably, one of the key challenges is to derive behaviors that are safe and comfortable but at the same time not overcautious, despite considerable uncertainties. These unc…
While complete localization approaches are widely studied in the literature, their data association and data representation subprocesses usually go unnoticed. However, both are a key part of the final pose estimation. In this work, we present DA-LMR (Delta-Angle Lane Marking Representation), a robus…
Comprehensive and correct state estimation with meaningful uncertainties is the basis of object-based perception for automated mobile platforms. According to fatality statistics, the most endangered group of vulnerable road users are single-track two-wheelers (ST2W), consisting mainly of cyclists, m…
Localization in aerial imagery-based maps offers many advantages, such as global consistency, geo-referenced maps, and the availability of publicly accessible data. However, the landmarks that can be observed from both aerial imagery and on-board sensors is limited. This leads to ambiguities or alia
In this paper, we present TEScalib, a novel extrinsic self-calibration approach of LiDAR and stereo camera using the geometric and photometric information of surrounding environments without any calibration targets for automated driving vehicles. Since LiDAR and stereo camera are widely used for sen…
While the automatic creation of maps for localization is a widely tackled problem, the automatic inference of higher layers of HD maps is not. Additionally, approaches that learn from maps require richer and more precise landmarks than currently available.In this work, we fuse semantic detections fr…
Despite recent advances in reinforcement learning (RL), its application in safety critical domains like autonomous vehicles is still challenging. Although penalizing RL agents for risky situations can help to learn safe policies, it may also lead to highly conservative behavior. In this paper, we pr…
Easy, yet robust long-term localization is still an open topic in research. Existing approaches require either dense maps, expensive sensors, specialized map features or proprietary detectors.We propose using semantic segmentation on a monocular camera to localize directly in a HD map as used for au…
Highly accurate localization with very limited amount of memory and computational power is one of the big challenges for next generation series cars. We propose localization based on geometric primitives which are compact in representation and further valuable for other tasks like planning and behav…
In autonomous driving systems a strong relation to highly accurate maps is taken to be inevitable, although street scenes change frequently. However, a preferable system would be to equip the automated cars with a sensor system that is able to navigate urban scenarios without an accurate map. We pre…
Reliable object perception is a vital requirement for automated driving. Despite the availability of precise contour measurements, most state-of-the-art tracking systems still represent object geometry as bounding boxes. However, there are objects operating in public traffic for which the box assump…
Accurate traffic participant prediction is the prerequisite for collision avoidance of autonomous vehicles. In this work, we propose to predict pedestrians using goal-directed planning. For this, we infer a mixture density function for possible destinations. We use these destinations as the goal sta…
The future of automated driving in urban areas will most probably rely on highly accurate road maps. However, the necessary precision of a localization in such maps has so far only been reached using extra, sensor specific feature layers for localization. In this paper we want to show that it is pos…
