Problems solved by technology

[0003] However, in the existing cooling system constructed in this way, regardless of the load conditions of the engine, the circulation path of the cooling water is switched at a certain temperature as a base point, and the cooling water temperature is kept at a certain level by utilizing the sudden opening determined by the mechanical characteristics of the thermostat. However, the temperature of the cooling water cannot be controlled to be constant at the optimum temperature. Therefore, not only thermal shock occurs in the engine cooling system, but also the detection of the cooling state of the OBD (On-Board Diagnostics) for vehicle self-diagnosis also occurs. stability problem

Embodiment Construction

[0017] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0018] figure 1 A schematic diagram of a vehicle engine cooling system according to a preferred embodiment of the present invention. Referring to this figure, it can be seen that the vehicle engine cooling system of the present invention is composed of a first circulation path and a second circulation path. The first circulation path is: the cooling water of the engine is pumped out by the water pump 1 through the cylinder block and the cylinder block of the engine 2 . The cylinder head absorbs the heat of the engine, and then flows into the water pump 1 again after passing through the heater core 3 to warm the vehicle; the second circulation path is: the cooling water of the engine is pumped out by the water pump 1 through the cylinder block and cylinder of the engine 2 The head absorbs the heat of the engine, and after the heat is released thro...

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...
