Abstract (en)
[origin: WO2011126431A1] The invention relates to a method for determining speed set-point values vref for a control system in a vehicle, which method comprises: A) determining a horizon by means of location data and map data for an itinerary made up of route segments and at least one characteristic for each segment; B) calculating speed set-point values vref for the vehicle's control system along the horizon on the basis of rules pertaining to characteristics of segments, and when a lowering of the vehicle's entry speed Vin, i to a segment is calculated to be necessary if the end speed vslut, i in the segment is to be = vmax and unnecessary braking thereafter is consequently to be avoided, the method comprises: C) calculating within the horizon a trigger location from which the fuel injection to the vehicle has to be throttled in order to achieve a lowering to Vin, i, provided that vm;n = vref = vmax, where vmin and vmax set the limits for permissible speeds for vref, which trigger location is subject to continued calculations of speed set-point values vref, and D) regulating the vehicle according to the speed set-point values vref. The invention relates also to a module arranged to calculate speed set-point values vref for a control system in a vehicle.
