Horizon Length and Fuel Equivalents for Fuel-optimal Look-ahead Control
Recent studies from several authors show that it is possible to
lower the fuel consumption for heavy trucks by utilizing information
about the road topography ahead of the vehicle. The approach in these
studies is receding horizon control where horizon length and residual
cost are main topics. To approach these topics, fuel equivalents
previously introduced based on physical intuition are given a
mathematical interpretation in terms of Lagrange multipliers. Measures
for the suboptimality, caused by the truncated horizon and the
residual cost approximation, are defined and evaluated for different
routes and parameters.
