Abstract: A thermal management system for a vehicle is disclosed, wherein the vehicle comprises an occupant compartment and a propulsion system configured to provide motive power to the vehicle. The system comprises a propulsion coolant circuit configured to cool at least a portion of the propulsion system, a heating circuit configured to heat the occupant compartment, and a heat pump circuit comprising a first evaporator in the propulsion coolant circuit and a condenser in the heating circuit. The propulsion coolant circuit comprises a connecting conduit connecting the propulsion coolant circuit to the heating circuit at a position upstream of the condenser, and a first valve configured to control flow of coolant through the connecting conduit. The present disclosure further relates to a powertrain for a vehicle, as well as a vehicle.

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.
