1. A vehicle safety system comprising a detection system and at least one control unit, where the detection system is arranged to detect objects, where the detection system includes at least two detectors, where the at least one control unit is configured to: determine that an object that is detected by an initial of the two detectors is classified as a confirmed object for the initial detector in a corresponding initial coverage area which the initial detector is arranged to cover; the control unit further is configured to: determine whether at least one detection of a other detector of the two detectors is likely to originate from the same object, and if that is the case to classify a first preliminary detection of the other detector as an intermediate low quality confirmed object for the other detector, where a low quality confirmed object is considered as a more reliable detection than a preliminary detection of the other detection, and where a confirmed object is considered as a more reliable detection than the low quality confirmed object.
