Abstract
A method for determining speed set-point values vfor a vehicle's control systems including determining a horizon from position data and map data of an itinerary made up of route segments with at least one characteristic for each segment; calculating threshold values for the characteristic of segments according to one or more vehicle-specific values, which threshold values serve as boundaries for assigning segments to various categories; comparing the characteristic of each segment with the calculated threshold values and placing each segment within the horizon in a category calculating set-point values for the vehicle's control systems across the horizon according to rules pertaining to the categories. When any characteristic in segments within the horizon indicates a hindrance, calculating the vehicle's retardation determining a start position within the horizon for commencement of retardation according to its calculated retardation in order to achieve a lowering of the set-point speed vto a maximum speed required by the hindrance at the location of the hindrance; adapting the speed set-point values vwithin the horizon according to the start position and retardation of the vehicle and regulating the vehicle's speed according to the speed set-values v. Also a module determines set-point values for a control system in the vehicle.
