First Claim
Patent Images
1. A method for determining, in a predictive manner, types of road situations of a vehicle, comprising the step for obtaining, from a navigation system, points defining at least one possible path situated in front of the vehicle, said method comprising the steps of:
- for each point, at least one attribute describing the type of road environment associated with this point in question is extracted from the navigation system;
the attribute of the point in question is compared with that of the preceding point;
if the attributes are identical, a driving situation is deduced from this such that said driving situation is a function of the attribute of the preceding point;
if the two attributes are different, an end of a driving situation is deduced from this and a transition to a new driving situation is determined as a function of the attribute of the point in question, so as to define a succession of driving situations for this path; and
a set of successive points is identified and a common road context is associated with the points of this set.

Abstract
A method for determining, in a predictive manner, types of road situations of a vehicle comprising the following steps:
- points defining at least one possible path situated in front of the vehicle are obtained from a navigation system,
- for each point, at least one attribute describing the type of road environment associated with this point is extracted from the navigation system,
- the attribute of this point is compared with that of the preceding point,
- if the attributes are identical, a driving situation is deduced from this such that said driving situation is a function of the attribute of the preceding point,
- if the two attributes are different, an end of driving situation is deduced from this, and a transition to a new driving situation is determined depending on the attribute of this point, in such a manner as to define a succession of driving situations for this path.

16. A system for determining, in a predictive manner, types of road situations of a vehicle, said system comprising:
-
a navigation system adapted to use points defining at least one possible path situated in front of the vehicle, said navigation system comprising; for each point, at least one attribute describing the type of road environment associated with this point in question is extracted from the navigation system; said at least one attribute of the point in question is compared with that of the preceding point; and if said attributes are identical, a driving situation is deduced from this such that said driving situation is a function of the attribute of the preceding point; if the two attributes are different, an end of a driving situation is deduced from this and a transition to a new driving situation is determined as a function of the attribute of the point in question, so as to define a succession of driving situations for this path; and said navigation system further identifying a set of successive points and a common road context is associated with the points of this set. - View Dependent Claims (17, 18, 19, 20)
