A system for governing a reference speed vref—dhsc for a downhill speed control system in a vehicle in connection with a downhill gradient. A simulation unit simulates at least one future speed profile vsim for an actual vehicle speed over a section of road in front of the vehicle, based on topographic information. An establishing unit establishes whether the reference speed vref—dhsc is to be allocated an increased reference speed vref—dhsc—schwung. This establishing is based on a comparison of the simulated future speed profile vsim with a permitted magnitude of the increased reference speed vref—dhsc—schwung and/or with an infringement speed vsl. An allocation unit allocates the value of the increased reference speed vref—dhsc—schwung to the reference speed vref—dhsc if this has been established.
