1. A method for determining set-point values for a vehicle's control systems, comprising the steps of: A) determining a horizon by means of position data and map data of an itinerary made up of route segments with at least one characteristic for each segment; B) calculating threshold values for said at least one characteristic of segments according to one or more vehicle-specific values, which threshold values serve as boundaries for assigning segments to various categories; C) comparing said at least one characteristic of each segment with the calculated threshold values and placing each segment within the horizon in a category according to the results of the comparisons; D) calculating set-point values for the vehicle's control systems across the horizon according to rules pertaining to the categories in which segments within the horizon are placed; E) regulating the vehicle according to the set-point values.
