Embodiment 1

[0028] The core of the invention is to detect the power supply circuit, and stop or reduce the power consumption of the electronic fan when the power supply is found to be insufficient, so as to achieve the purpose of protecting the storage battery. According to the first embodiment of the present invention, a method for controlling an electronic fan for cooling a radiator of a vehicle engine is as follows: figure 1 shown. In this figure, the solid connecting line represents the power supply line (there are two lines, positive and negative), and the dashed connecting line represents the information connection (which can be wireless); the engine 1 and the radiator (water tank) 2 exchange heat through cooling water; The electronic fan controller 5 controls the electronic fan 3 according to the temperature information of the radiator (water tank) provided by the radiator (water tank) temperature sensor 4 after reaching the set standard, and performs the heat dissipation work of t...

Embodiment 2

[0032] The core of the invention is to detect the power supply circuit, and stop or reduce the power consumption of the electronic fan when the power supply is found to be insufficient, so as to achieve the purpose of protecting the storage battery. According to the second embodiment of the present invention, a system for controlling an electronic fan for cooling a radiator of a vehicle engine such as figure 2 shown. In this figure, the solid connecting line represents the power supply line (there are two lines, positive and negative), and the dashed connecting line represents the information connection (which can be wireless); a system for controlling an electronic fan for cooling the radiator of a vehicle engine, it include:

[0033] Radiator (water tank) temperature sensor 4; radiator (water tank) heat dissipation electronic fan 3; battery 7; generator 8; detection component 6; electronic fan controller 5;

[0034]The battery 7 and the generator 8 form a power supply cir...

Abstract

The invention aims to provide a method for controlling a cooling fan of an engine and a system. Design margin of unusually used equipment in a power supply system is provided for the electronic fan. Operation of the electronic fan is stopped or reduced by means of detecting a power supply state, and a purpose of protecting storage batteries is achieved.

Description

technical field [0001] The invention belongs to the field of vehicle control. The present invention relates to a method and system for controlling an electronic fan for cooling a radiator of a vehicle engine. Specifically, it relates to a method and system for protecting a battery on a power supply line while controlling an electronic fan for cooling a radiator of a vehicle engine. Background technique [0002] Nowadays, many vehicles, especially passenger cars, use diesel engines, and fuel saving has received widespread attention. However, because its traditional engine radiator cooling system follows the truck's "non-temperature control" and "non-working continuous drive" features, these features determine the high fuel consumption of the cooling system. The traditional concept is that the water tank does not "boil the pot", the engine is often lower than the standard temperature, the thermal efficiency is low, and the fuel consumption is high; when the engine is applied...
