Method and apparatus for controlling water temperature of engine
Provided is a method for controlling a water temperature of an engine. The method includes: collecting outlet water temperatures of the engine at predetermined time intervals (S101); when a number of the collected outlet water temperatures of the engine is greater than or equal to a predetermined number, determining a water temperature variation function of the outlet water temperatures of the engine with time according to collected each outlet water temperature of the engine and collection time corresponding to the each outlet water temperature of the engine (S102); and determining performance parameters of a cooling system under the water temperature variation function, and controlling controllable parts of the cooling system according to the performance parameters of the cooling system (S103). Further provided is an apparatus for controlling the water temperature of the engine.
