FIELD: transport.
SUBSTANCE: invention relates to method for vehicle speed control. When vehicle speed control is executed desired vehicle speed vset is accepted; targeted path horizon is determined using map data and position data. The first vehicle speed prediction vpred_cc over horizon is executed using conventional cruise control system when vset is given as reference speed. Predicted vehicle speed vpred_cc is compared with vmin and vmax which limit range within which vehicle speed is targeted. The second vehicle speed prediction vpred_Tnew over horizon is executed when vehicle engine torque T depends on the result of the mentioned comparison with in the last previous simulation pass (s-1). Based on at least one of the mentioned comparisons in this simulation pass (s) and predicted vehicle speed vpred_Tnew a reference value is determined which indicates how to act on vehicle speed. Reference value is sent to vehicle control system relative to which value the vehicle is subsequently adjusted.
EFFECT: fuel saving, mileage reduction.
