A method and system for controlling a cooling fluid pump 6 of a cooling system for cooling intake air of an internal combustion engine 3 of a vehicle by a heat exchanger 2 supplied by cooling fluid delivered by said pump 6. The method comprising controlling (S40, S60, fig.2) a fluid flow parameter (Qw, fig.2) of the pump 6 based on the vehicle speed parameter (v, fig.2), an intake air flow parameter (QA, fig.2) of said engine 3 and/or a cooling fluid temperature parameter (Tw, fig.2) of said cooling fluid. The air intake may further comprise a compressor, such as a turbocharger, and/or an exhaust gas recirculation (EGR) system. The invention improves the performance of the cooling system by limiting the fluid flow (parameter) of the pump by an upper fluid flow threshold beyond which there is little or no improvement in efficiency thus control of the pump may be improved. |
