A benchmark problem for fuel efficient control of a truck with engine, driveline, and chassi models on a given mission with a road topography profile is formulated. The Vehicle model is provided with open access to the vehicle model equations and parameters. It is compiled from model components validated in previous research projects and the result is a non-linear model that contains mixed continuous and discrete control variables. The driving; scenario is provided as road slope profile and a desired trip time. The problem to solve is a combination of engine-, driveline- and Vehicle-control while fulfilling demands on emissions, driving time, legislative speed, and engine protections.
