The eco-driving score measures the difference between the energy consumed and the minimum energy achievable on the journey. This score is constructed by comparing the vehicle's travel speed achieved by the driver with a reference speed trajectory.
E.g. If you get a score of 8/10, you could have saved 20% of energy.
The app provides a reference, which is essential to assess potential gains or to compare drivers using different vehicles and not using the same roads. The algorithm for calculating this indicator is the result of several years of research and its principle has been patented.
