    Abstract: 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.

    Abstract: A regulating device (2) for a viscoclutch (4) which is provided with a primary disc (6) and a secondary disc (8), the primary disc having a first rotation speed (10) and the secondary disc a second rotation speed (12). The regulating device (2) receives signals which represent the rotation speeds and a desired degree of engagement (14), and calculates a prevailing degree of engagement (15) between the discs (10). The degree of engagement between the discs is controlled by regulating an amount of viscous oil between them by delivering a control signal (16) to an oil pump unit (18) which pumps oil (20) into the viscoclutch (4). The nature of the engagement, and controlling for maximum to minimum engagement is disclosed.
