THE IMPACT OF ECOROLL ON FUEL CONSUMPTION - USING LOOK AHEAD
KTH, School of Electrical Engineering (EES), Automatic Control.

Abstract [en]

EcoRoll reduces fuel consumption with small development costs, since no additional hardware is required. It is a function that enables a more efficient conversion of potential to kinetic energy, when travelling downhill. This is achieved by opening the powertrain, and let the engine run on idle to reduce engine losses. In this Master’s thesis, two control strategies were developed, where one is based on prevailing conditions and one utilizes Look-Ahead data. Compared to a vehicle with a conventional cruise control, the first strategy gave a fuel reduction of approximately 3.4% and the other 3.7%. This was simulated on the highway between Södertälje and Norrköping in Sweden.
