Embodiment Construction

[0063] The present invention will be described with reference to particular embodiments and with reference to certain drawings but the invention is not limited thereto but only by the claims. The drawings described are only schematic and not restrictive. In the drawings, the size of some of the elements may be exaggerated and not drawn on scale for illustrative purposes only. Where the term "comprising" is used in the description and claims, it does not exclude other elements or steps. Where an indefinite or definite article is used when referring to a singular noun (eg, "a" or "the", "said"), this includes a plural of that noun unless something else is stated.

[0064] The term "comprising", used in the claims, should not be interpreted as being limited to the means listed thereafter; it does not exclude other elements or steps. As such, the scope of the expression "apparatus comprising means A and B" should not be limited to an apparatus consisting of components A and B on...

Abstract

The invention relates to a vehicle or traffic control method and to a vehicle or traffic control system. The vehicle or traffic control method comprises the steps: a) estimating actual and / or future behavior of a first traffic participant and of a second traffic participant, respectively, the second traffic participant being different from the first traffic participant, b) estimating a trajectory to be taken by the first traffic participant and / or a trajectory to be taken by the second traffic participant, c) determining risk of collision of the first traffic participant relative to the second traffic participant by calculating information adapted for risk assessment of collision of the first traffic participant relative to the second traffic participant, and d) controlling the behavior of the first traffic participant based on the information provided after step a), step b); and / or step c). In this way a probability value is determined which indicates the plausibility that a vehicle or traffic participant might enter into collision within a certain time horizon in the future.

Description

technical field [0001] The present invention relates to an assisted driving method or a vehicle or traffic flow control method or an assisted vehicle guidance method and an assisted driving system, a vehicle or traffic flow control system or an assisted vehicle guidance system, preferably for passive or active vehicle safety and use Software for implementing related systems or methods. Background technique [0002] Document WO 2006 / 021813A1 describes a method for collision avoidance, for a collision avoidance system of a subject vehicle, the system comprising a detection system adapted to detect an intruding vehicle in a predetermined area around the subject vehicle and collect data on the intruding vehicle means; means for predicting a predetermined trajectory of an intruding vehicle in the frame of reference of a subject vehicle; means for determining a protected area around the subject vehicle; Whether the predetermined trajectory will intercept the subject vehicle prote...
