Techniques for clustering sensor data are discussed herein. Sensors of a vehicle may detect data points in an environment. Clustering techniques can be used in a vehicle safety system to determine connection information between the data points. The connection information can be used by a vehicle computing device that employs clustering and/or segmenting techniques to detect objects in an environment and/or to control operation of a vehicle.

The invention relates to a method for diagnosing error of at least one of an ego vehicle (10) and a surrounding vehicle (12), which method comprises the steps of: the ego vehicle (10) receiving (S1) sensor data about the surrounding vehicle (12) from an on-board sensor (14) of the ego vehicle (10) and vehicle to vehicle data from the surrounding vehicle (12); the ego vehicle (10) comparing (S2) the received sensor data and the received vehicle to vehicle data; and the ego vehicle (10) detecting (S3) a difference between the received sensor data and the received vehicle to vehicle data, whereby the ego vehicle (10): stops (S4) receiving vehicle to vehicle data from the surrounding vehicle (12); registers (S5) a potential error of the ego vehicle (10); and reports (S6) a potential error of the surrounding vehicle (12) to at least one of the surrounding vehicle (12) and a remote server (18). The invention also concerns a method for diagnosing error of a surrounding vehicle (12).
