Time-Series Anomaly Detection for Mobile Robots in Automotive Active Safety Testing using an RNN-VAE

Henrik Meyer, Karsten Raguse, Armando Walter Colombo, Thomas Seel, Simon F. G. Ehlers

Mobile robots, like the ultra-flat overrunable (UFO) robot platform, used in automotive active safety tests, currently lack self-diagnostic capabilities necessary to detect present hardware defects. This circumstance can lead to more severe failures, causing expensive repairs and…

Hybrid Machine Learning for Articulation Angle Estimation of Truck-Semitrailer Combinations

Qixuan Zhang, Jonas Boettcher, Simon F. G. Ehlers, Marvin Stuede

Accurate articulation angle estimation of trucks with trailers is critical for autonomous driving and advanced driver assistance system (ADAS). Existing methods either require manual initialization, additional sensors, or prior knowledge and signals from trailers, or they lack re…
