Abstract
Described is a method for determining a reference value for a vehicle. The method includes: performing a number of simulation cycles Seach comprising simulation steps: making a first prediction of the vehicle's speed valong the determined horizon with a conventional cruise control; comparing, in a first comparison, the predicted vehicle speed vwith Vand V, which define a motor torque used in a subsequent simulation cycle; making a second prediction of the speed when the engine torque is a value that depends on the result of said comparison in the latest preceding simulation cycle; comparing, in a second comparison, the predicted vehicle speed vwith v, and Vwhich demarcate a range within which the speed is maintained; determining the reference value based on the second comparison and/or the second predicted speed in that simulation cycle S; and controlling the vehicle according to the reference value.
