Patent ID: 8849539

Claim:
A method for determination of speed set-point values v ref for a vehicle's control systems, the method comprising: A) determining a horizon using position data and map data of an itinerary made up of route segments with length and gradient characteristics for each segment; B) 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; C) 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; D) calculating speed set-point values v ref 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) adding an offset v offset to the calculated speed set-point values v ref when the vehicle is in a segment which is in a category indicating a steep upgrade or a steep downgrade; and F) regulating the vehicle according to the speed set-point values v ref .
