<p>The invention relates to a method (100) for regulating the temperature of a motor vehicle engine, wherein a heat-transfer fluid is circulated (102) in a radiator, close to the engine, by means of a pump, a temperature (T°|iq_mes) of said fluid is measured (108), air is swept through (104) said exchanger by means of a ventilator, a flow rate (Qair_cal) of the air flowing through said exchanger is calculated (110), a temperature (T °mot_dét) of said engine is determined (101), a nominal set value of the rotational speed (VNrot_Cons) of said ventilator and a flow rate set value (Qliq_cons) of said pump are deduced (109) from said temperature of the fluid and from said air flow rate, safety set values of the rotational speed (VSrot_cons) of said ventilator and the flow rate (QSiiq cons) of said pump are deduced (105) from said temperature of the engine, the nominal and safety set values are synthesised (160; 162) in order to obtain two synthesised set values (VMAXrot_cons; QMAXliq_cons), the ventilator is controlled (118) by applying (120) said synthesised speed set value thereto, and the pump is controlled by applying (122) said synthesised flow rate set value thereto.</p> |
