1. A method of determining at least one eco-driving indicator of travel of a vehicle, the travel corresponding to motion of the vehicle between two successive stops of the vehicle, comprising:

  • a) measuring an instantaneous speed of the vehicle during the travel;

    b) identifying at least one breakpoint of the travel with each breakpoint being associated with a travel constraint where the instant speed has been modified according to conditions external to the travel;

    c) dividing the travel into at least one segment with each segment being defined between two successive breakpoints and determining for each segment a distance and an average speed of the segment by the measured instant speed; and

    d) determining, as a first eco-driving indicator, an optimal speed of the travel, the optimal speed being calculated for each segment by an optimization algorithm implemented in a program executed on a computer that determines a speed minimizing energy consumption of the vehicle with the algorithm being constrained by the measured instant speed at the breakpoints, by the distance and by the average speed of the segment.
