Method for determination of optimal parameters of conduct and help system has the corresponding eco-driving.

This process compares optimal current consumption to an actual instantaneous consumption. The optimal consumption is calculated based on: - the characteristics of the vehicle - traffic conditions, - time constraints predeterminees.Les vehicle characteristics and traffic conditions to determine a cost associated with fuel consumption depending on vehicle speed and speed limit values ​​admissible.Les time constraints to determine a cost associated with a possible increase in travel time, the resulting cost function is analyzed to determine optimal operating parameters, and indications are given to the driver so that he can act on his conduct in order to achieve optimal consumption.
