Abstract
A method for determining a reference value for controlling a vehicle's speed by a vehicle control system is described. The method includes: making a first prediction and a second prediction of the speed along a horizon, the first prediction based on an engine torque that retards the vehicle as compared with a conventional cruise control, and the second prediction based on an engine torque that accelerates the vehicle as compared with the conventional cruise control; comparing the first prediction and second prediction, respectively, with a lower limit value and/or an upper limit value, which delineate a speed range within which the speed is to be maintained; and determining the reference value based on at least one of the respective comparisons and the first prediction and second prediction so that the set speed is within the speed range bounded by the lower and upper limit values.
