  • Patent number: 12049227
    Abstract: The invention is a method for determining a speed profile for minimizing emissions of at least one pollutant generated by a vehicle during a journey. The method requires a model of the vehicle dynamics, an analytical model of the emissions of the pollutant, and at least one speed profile model divided into at least two phases, each of the phases corresponding to a traction acceleration mode of the vehicle with a number of acceleration modes preferably being five. Then, a speed profile minimizing the emissions of at least one pollutant is determined by seeking, from speed profiles with respect to the distance, duration, and initial and final speeds of the journey and distinguished by distinct phase durations with the speed profile for which the emissions of the pollutant are modelled is by use of an analytical model for which the pollutants are the lowest.

  • Patent number: 11345355
    Abstract: The present invention is a method for determining an optimal speed of a first vehicle preceded by a second vehicle. Position, speed and acceleration of the second vehicle are measured in order to determine a trajectory thereof, and a dynamic model of the first vehicle is constructed. The optimal speed is then determined by minimizing the energy consumption of the vehicle by use of the dynamic model by minimization being constrained by the trajectory of the second vehicle.
