摘要
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.
