Abstract: A method for grouping traffic light structures of a traffic light system, wherein each traffic light structure has at least one traffic light that can be activated, and wherein a first traffic light structure controls at least a first direction of travel. The method includes: ascertaining a relation of activated traffic lights to one another; grouping the traffic light structures taking into account the ascertained relation. A device and a corresponding computer program are also described.

Abstract: A method for the early recognition of a stopping position for a driver assistance system of an ego vehicle at a stop signal by a light signal system. An enlarged working area and increased possible speeds are achieved in that a stop signal of a light signal system for an ego roadway of the ego vehicle is recognized; if a stop signal is recognized, the ego roadway is searched for a crosswalk, wherein if a crosswalk is recognized, the crosswalk is used for the early recognition of a stopping position of the ego vehicle. A computer program product for performing the method and a motor vehicle performing the method are also described.

Abstract: A method for determining a signal state of a light signal system having several light signal emitters, wherein the light signal system comprises several signal states and a signal state is formed by means of one or more activated light signal emitters. The method includes: determining an object, which represents a signal state of a light signal system; saving a determined first object having a first identifier, if it is detected in a first video image that the first object represents a signal state of the light signal system; changing the identifier of the saved first object from the first identifier to a second identifier, if in a second video image the first object is no longer detected; deleting the saved first object having the second identifier, if a second object is determined in a further video image, which represents a different signal state of the light signal system.

Abstract: An operating assistance method for a working device or for a vehicle. Object boxes for an object in a field of view of the working device are obtained at consecutive times. From object boxes of a given object, for images recorded in succession or direct succession, an instantaneous change of scale of an object box for the specific object, and an instantaneous lateral change of position of the object box for the specific object, are determined. An object box predicted in the future is determined from the current change of scale, and from the instantaneous lateral change in position for an object box for a specific object. The position of the predicted object box and/or the ratio of a lateral extension of the predicted object box to a lateral extension of a covered field of view and/or of the recorded images are determined and evaluated.
