Abstract
A method for controlling a cooling system delivering coolant to a heat exchanger (18) in a vehicle (1). During operating conditions when a thermostat (6) in the cooling system is in the partly open position, the method comprises the steps of estimating a desired cooling temperature (T) of a medium in the heat exchanger (18), calculating the coolant flow rate ({dot over (m)}1) through a radiator (7b) and the coolant flow rate ({dot over (m)}2) through a radiator bypass line (9), calculating a coolant flow rate ({dot over (m)}3) and coolant temperature (t3) combination at 10 at which the medium in the heat exchanger (18) is cooled to a desired temperature (T), adjusting the flow regulating mechanism (23) such that coolant at the selected flow rate ({dot over (m)}3) and temperature (t3) combination is directed to the heat exchanger (18).
