Abstract:
A device for regulating the cooling of a motor vehicle internal combustion engine, of a type comprising a fluid-cooling circuit coupled to a fluid pump for cooling the internal-combustion engine the operation of which is defined at any moment by a prevailing load and a rotational speed, the circuit feeding an installation for heating and/or air conditioning a passenger compartment of the vehicle, with adjustable air-heating parameters, including an air heater, the device further comprising:determining means for establishing an engine-starting stating state on the basis of chosen conditions; and a control means for controlling the pump which is active in the starting state so as, depending on a quantity representative of the heating demand and on at least one other quantity, either to stop the pump if a heating demand is below a certain threshold, or else to drive the pump as a function of a saturation rotational speed.
