A system for control of temperature for a vehicle exhaust treatment system comprising a first determination unit arranged for determination of a temperature for the exhaust treatment system, and a simulation unit arranged for simulation of a future velocity profile, based on information relating to a road section. A second determination unit arranged for determination, based on a future velocity profile, of whether a simulated active brake process due to an over-speed for the vehicle will occur within the road section. A utilization unit is arranged for utilization, if the at least one temperature for the exhaust treatment system is below a minimum temperature threshold value, and if the simulated active brake process is simulated to occur within the road section, of an engine fitted auxiliary brake, which is fitted in connection with an exhaust stream from an engine in the vehicle, where the utilization is initiated before over-speed occurs. |
