METHOD FOR EARLY OPENING OF A COLD THERMOSTAT IN AN ENGINE COOLING SYSTEM

The invention concerns a method for early opening of a cold controlled thermostat in a system for fluid cooling of a heat engine, the thermostat operating a closure and an at least partial opening of a heat exchange circuit with respect to a main circuit of the system, the thermostat being controlled by a regulating command (Creg) for opening based on a current temperature (Tf) of the fluid and a setpoint temperature (Tcons). A corrective command (Ccor) for opening the thermostat is established when a variation between the current temperature (Tf) and the setpoint temperature (Tcons) is less than a first predetermined threshold (S1) and when at least one operating condition of the engine or at least one external climatic condition has been recognised by experience as involving a temperature difference (dT) between the respective fluids of the heat exchange and main circuits above a threshold of temperature variation between fluids. 本发明涉及一种用于提前开启冷却系统中的冷态受控节温器的方法，所述冷却系统通过载热流体对热机进行冷却，所述节温器使热交换回路相对于所述系统的冷却主回路关闭和至
