at least a first instant during the journey, a step of determining an instantaneous position of the vehicle at this first instant and a desired time remaining to reach the destination,
a step of identifying, among the mission profiles, the mission profile(s) whose curves are closest to the desired time remaining at the instantaneous position of the vehicle, and
a step of determining new driving parameters to follow a new mission profile, the new mission profile being determined on the basis of the determined mission profiles.
