Abstract
A method for determination of speed set-point values vfor a vehicle's control systems, includes determining a horizon from position data and map data of an itinerary made up of route segments with length and gradient characteristics for each segment; calculating threshold values for the gradient of segments according to one or more vehicle-specific values, which threshold values serve as boundaries for assigning segments to various categories; comparing the gradient of each segment with the threshold values and placing each segment within the horizon in a category according to the results of the comparisons; calculating speed set-point values vfor the vehicle's control systems across the horizon according to rules pertaining to the classes in which segments within the horizon are placed; adding an offset vto the calculated speed set-point values vwhen the vehicle is in a segment which is in a category indicating a steep upgrade or a steep downgrade; regulating the vehicle according to the speed set-point values v. A module determines of speed set-point values for a vehicle's control systems.
