Method for determining, in a predictive manner, types of road situations for a vehicle

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.
