Abstract

Provided is a vehicle engine cooling system control device and its method for preventing the sensing instability of thermal shock and a cooling condition by optimally controlling the temperature of cooling water in accordance with the loaded conditions of an engine. The vehicle engine cooling system control device is provided for a vehicle engine cooling system in which cooling water pumped by a water pump is circulated passing through the engine and a radiator in sequence to cool the engine. It comprises an electronic valve means for adjusting the amount of the cooling water to be circulated through the radiator, a temperature sensing part for sensing the temperature of the cooling water passing through the engine, and a control part for controlling the valve opening / closing amount of the electronic valve means in accordance with the temperature of the cooling water sensed by the temperature sensing part and a target set temperature.

Description

technical field

[0001] The present invention relates to a vehicle engine cooling system control apparatus and method, and more particularly, to a vehicle engine cooling system control apparatus and method capable of preventing thermal shock of the cooling system while optimally controlling the cooling water temperature. Background technique

[0002] Generally, in the vehicle water-cooled cooling system, the cooling water of the engine is pressed out by the water pump and passes through the cylinder block and cylinder head of the engine in sequence, and absorbs the heat of the engine, and then is discharged through the outlet of the cylinder head, and is released through the heater or radiator. After it is heated, it is cooled by the circulation process that flows into the cylinder block of the engine through the water pump. In addition, the outlet of the engine is provided with a thermostat that switches the circulation path of the cooling water by opening and closing accord...
