1. A method for governing a reference speed vref

  • dhsc for a downhill speed control system in a vehicle in connection with vehicle travel on a downhill gradient, which enables an increased reference speed vref

    dhsc

    schwung of the vehicle in a final part of said gradient,the method comprises;

    simulating at least one future speed profile vsim for an actual speed for said vehicle on a section of road in front of said vehicle, wherein said simulation is based on topographic information;

    establishing whether said reference speed vref

    dhsc is to be allocated said increased reference speed vref

    dhsc

    schwung, wherein said establishing is based on a comparison of said simulated future speed profile vsim with a permitted magnitude for said increased reference speed vref

    dhsc

    schwung and/or with an infringement speed vsl, andallocating said increased reference speed vref

    dhsc

    schwung to said reference speed vref

    dhsc if said establishing has been accomplished.
