Abstract

The invention provides a cooling fan system of an engine and a cooling fan control method used for the same The system comprises a multi-stage cooling fan unit used for cooling an engine, and a fan control unit used for controlling all stages of fans in the multi-stage cooling fan unit to open or close according to the real-time working temperature of the engine. The control method comprises the following steps of: setting the opening or closing temperature values of all stages of fans; acquiring the real-time working temperature of the engine; judging whether the real-time working temperature of the engine reaches the opening and closing temperature values of the all stages of fans or not, and if the real-time working temperature reaches the opening and closing temperature values, sending opening or closing control signals for opening or closing the all stages of fans; and controlling all stages of fans to open or close according to the control signals. The invention can carry out intelligent and reliable fan starting or opening control according to the preset temperature and the real-time working temperature of the engine, is suitable for a plurality of fans or multi-stage running fans, and has the characteristics of simple structure, easy realization, energy saving and noise reduction.

Description

technical field [0001] The present invention relates to an automobile engine cooling system, more specifically, to an engine cooling fan system and a cooling fan control method for the system. Background technique [0002] At present, only one fan is usually used in the engine cooling system to cool down the exhaust air, and the single fan control is carried out through the temperature signal detection and logic control of the engine ECU itself. This kind of fan control method has poor reliability and cannot adapt to real-time changes in engine temperature. Therefore, it is necessary to provide a fan system with multi-level cooling capability and an intelligent fan control method. Contents of the invention [0003] The present invention aims to provide an engine cooling fan system and a cooling fan control method used in the system, which can solve the technical problems of poor cooling effect of the engine cooling fan and low reliability and intelligence of the control me...
