Förfarande och system för styrning av ett kylsystem i ett fordon

摘要

A method and a system for controlling a vehicle cooling system includes: a velocity prediction unit makes a prediction of at least one future velocity profile vpred for the vehicle; a temperature prediction unit predicts at least one future temperature profile Tpred for at least one component in the vehicle, based on at least tonnage for the vehicle; information related to a section of road ahead of the vehicle and on the at least one future velocity profile vpred. A cooling system control unit controls the cooling system based on the at least one future temperature profile Tpred and on a limit value temperature Tcomp—lim for the respective at least one component in the vehicle so that a number of fluctuations of an inlet temperature Tcomp—fluid—in—radiator for the cooling fluid flow into the radiator is reduced and/or so that a magnitude of the flow into the radiator is reduced when a temperature derivative dT/dt for the inlet temperature Tcomp—fluid—in—radiator exceeds a limit value dT/dtlim for the temperature derivative.
