Abstract

Embodiments of the invention provide a temperature adjusting method, device and system and an electronic control unit. The method comprises the steps that the rotating speed and load rate of an engineare obtained, and the operation condition of the engine is determined according to the rotating speed and load rate; a current temperature of engine oil in a main oil duct of the engine is obtained;a bypass valve is adjusted according to the operation condition of the engine and the current temperature to adjust the temperature of engine oil in the main oil duct, adjustment of the temperature ofthe engine oil in the main oil duct is achieved, the temperature of the engine oil in the main oil duct is matched with the operation condition, that is, the temperature of the engine oil in the mainoil duct is proper and not too high or too low, and accurate adjustment of the temperature of the engine oil in the main oil duct is achieved, so that the reliability of the engine is improved, the friction work of the engine is reduced, and the fuel economy is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicles, and in particular to a temperature adjustment method, device, system and electronic control unit. Background technique [0002] Engine oil, that is, engine lubricating oil, can lubricate and reduce friction for the engine, assist cooling and cooling, seal and prevent leakage, prevent rust and corrosion, shock absorption and buffering, etc. [0003] At present, when the vehicle is running, when the temperature of the engine oil in the vehicle is too high, the risk of engine failure is high, so the reliability of the engine cannot be guaranteed. When the temperature of the oil in the main oil gallery of the engine in the vehicle is too low, the frictional resistance of the engine is relatively large, that is, the friction work is relatively large. The method of controlling the oil temperature in the main oil passage to prevent the oil temperature in the main oil passage ...
