Abstract
A method performed by a behavioral analyzing system for detection of an emergency vehicle approaching a vehicle from behind. The system derives a road configuration of a road along which the vehicle, based on ego-vehicle position obtained with support from localization sensors on-board the vehicle, is or was positioned. The system further determines unconventional driving criteria in view of the road configuration. The system determines based on surrounding vehicle detection data of a first and at least a second surrounding vehicle, obtained with support from surrounding detecting sensors on-board the vehicle, a respective first and at least a second surrounding vehicle trajectory along at least the road section. The system determines, when the first and the at least second surrounding vehicle trajectory fulfill at least a portion of the unconventional driving criteria, that an emergency vehicle is deemed to be approaching the vehicle from behind.
