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.

Abstract: A free space-verification system and a method performed by a free-space verification system and for supporting and/or providing confidence in that a perception system of an ADS of a vehicle detects presence of objects. The system obtains sensor data of vehicle surroundings; generates perception data of vehicle surroundings based on fusing the sensor data; determines that the perception system perceives at least a first zone in the vehicle surroundings, free from objects; separately evaluates obtained sensor data to encounter potential sensor-specific detections in an at least first extended zone at least partly encompassing the at least first zone; and determines when respective potential sensor-specific detections within the at least first extended zone for a predeterminable number of and/or combination of the surrounding detecting sensors, comply with at least a first free-space verifying criterium, that the at least first zone is verified as object-free.

Abstract: An object validation system for validating perceived surrounding objects to support safety-critical threat assessment governing emergency maneuvering of an ADS on-board a vehicle. The system stores in respective sensor/modality-specific data buffers, respective sensor/modality-specific sensor data obtained at least during a predeterminable time interval continuously and/or intermittently from one or more vehicle-mounted surrounding detecting sensors. The system determines with support from a perception module configured to generate perception data based on sensor data from one or more vehicle-mounted surrounding detecting sensors, object data of a perceived object valid for the time interval. The system evaluates one or more of the respective sensor/modality-specific data buffers, separately, in view of the object data.

Abstract: A novel gear well (200) for a crusher (1) may be characterized in that the recess (210) comprises a helical, non-uniform depth recess having a high point (212A) and a low point (212B). The gear well (200) may be further characterized in that rather than extending to a sharp corner transition (112) and then to an orthogonal sidewall (126), the floor (211) of the recess (210) may instead intersect or blend with the pinion clearance floor (222) adjacent the low point (212B). The helical, non-uniform depth recess (210) is preferably configured for improving the strength of a gear well (200) and/or configured for mitigating oil frothing within the gear well (200), without limitation.

Abstract: Disclosed herein is a method and arrangement for monitoring and adapting the performance of a fusion system of an autonomous road vehicle. A drivable area is determined by combining a localization function and high density map data. Information on surrounding objects is determined, comprising determining the localization and classifying the surrounding objects, estimating their physical property states, and assigning them extension descriptions. Information on the drivable area and surrounding objects is condensed into observed areas, monitored by sensors of the environmental perception function with a predetermined degree of certainty, and prioritized objects, represented by classes, state estimates and extension descriptions.

Abstract: Surveillance system for automatic detection and presentation of threat indications, the system comprising several threat indication detectors and at least one central unit adapted for communication with said threat indication detectors and for presentation of threat images. Threat information signals are transferred automatically from the threat indication detectors to the central unit, and each threat indication detector can be located both immobile, semi-mobile of mobile.
