When two target objects cannot see each other and at least one of them is a moving object following lanes, the warning system identifies the couples of two predicted trajectories having at least one point in common or an inter-trajectory distance less than a distance threshold (d), among all possible couples of two predicted trajectories for the two respective target objects, then calculates a probability of collision for each identified couple of trajectories, by determining a predicted collision time and calculating probability distribution functions for the positions of the two target objects at said predicted collision time, and checks whether or not the probability of collision calculated for at least one of the identified couples of trajectories is more than a collision probability threshold in order to trigger an alert towards at least one of the two target objects.

Warning system for a host automotive vehicle

A method for identifying objects in a traffic space by means of a sensor system arranged at or in a host vehicle comprises the steps of determining the positions of a plurality of object surface spots detected by the sensor system in a vehicle coordinate system, assigning the determined positions of object surface spots to at least one detection group by means of a clustering algorithm, wherein the clustering algorithm uses clustering regions defining threshold distances, and identifying at least one object by determining that positions of object surface spots belonging to the same detection group form part of a single object. The determined positions of object surface spots are transformed in a transformation process and the clustering algorithm is applied to the transformed positions of object surface spots. The transformation process includes a directional scaling step that renders the clustering regions non-circular in the vehicle coordinate system.

Method for identifying objects in a traffic space

A method of generating a polyline representing a contour of one or more objects includes the steps a) formulating a series of spatially ordered points in 2-dimensional space, each representing a (point) detection with respect to object(s); b) connecting the end points of the series of ordered points with a first straight line segment, and determining the shortest distance between each of the intermediate points and the first segment; c) determining from step b) a threshold based on a measure of the dispersion of the intermediate points around the segment; d) for each side of the segment determining, for any points that lie on that respective side, the point which is further from the segment; e) determining any of the points found in step d) which are further from the segment than the threshold; f) formulating a polyline by connecting the end points of the points determined from step e).
