Abstract

A method of operating a data recording device for Autonomous Driving, or Advanced Driver Assistant Systems applications for vehicles is provided. The data recording device comprises a data logging unit, a computing unit, a storage unit and a relevancy determination unit including at least one relevancy determination module. The storage unit includes a circular buffer and a persistent storage region. The method comprises retrieving sensor data acquired by sensors, storing the sensor data in the circular buffer, retrieving and storing perception results or neural network embeddings from the sensor data and deciding whether the retrieved perception results or neural network embeddings are considered relevant or irrelevant, and triggering a transfer of the sensor data from the circular buffer to the persistent storage region in case the perception results or neural network embeddings corresponding to the sensor data are considered relevant.
