This patent describes a method and a device for providing energy-optimal driving (ecodriving) of (semi)autonomous vehicle in presence of dynamically arising traffic situation dependent additional constraints (i.e other moving vehicles, traffic signs not known during initial planning step, etc.). The controlled vehicle is moving on an optimal speed trajectory (derived at least based on road gradient information) and approaching slowly the moving leading vehicle or the traffic sign not known during initial planning step. The proposed system generates an appropriate modified trajectory to overcome the newly arisen constraints and the decision whether to overtake or not (in case the constraint is a leading vehicle) aiming achieving global energy optimal motion. The trajectory and the decision are obtained based on previously derived optimal speed trajectory tree, cost-to-go map and leading vehicle motion prediction.
