Description

    CROSS-REFERENCE TO RELATED APPLICATION
  • The present application claims priority of Korean Patent Application Number 10-2013-0157987 filed on Dec. 18, 2013, the entire contents of which application are incorporated herein for all purposes by this reference.
  • BACKGROUND OF INVENTION
  • 1. Field of Invention
  • The present invention relates to a cooling system for a vehicle and a control method therefor, and more particularly, to a cooling system for a vehicle and a control method therefor capable of effectively controlling a cooling amount without a thermostat and/or a control valve, by controlling an introduced air amount and a coolant flow rate passing through a radiator by controlling an air flap apparatus in a vehicle in which the air flap apparatus is equipped.
  • 2. Description of Related Art
  • As is generally known, as one of the technologies of improving fuel efficiency of a vehicle in a car maker, various researches for cooling a power train system, that is, cooling an engine system have been conducted.
  • Among various researches, research and development of an electric cooling system configured by replacing a mechanical water pump with an electric water pump has been frequently made. The reason of replacing the mechanical water pump with the electric water pump is as follows.
  • That is, the mechanical water pump is operated in proportion to an engine revolution speed, that is, depending on the engine revolution speed, and thus is operated regardless of a required amount for cooling, which leads to a loss of energy in some sections and exerts a bad influence on fuel efficiency. To prevent the loss, a cooling system using an electric water pump which may be operated by an external control has been researched and developed and applied.
  • An example of the existing cooling system using the electric water pump as described above is illustrated in FIGS. 1 to 3.
  • Referring to FIG. 1, the cooling system is configured by simply replacing a mechanical water pump with an electric water pump 20 in the cooling system using the mechanical water pump. That is, the electric cooling system illustrated in FIG. 1 uses a thermostat 30 applied to the mechanical cooling system as it is. Reference numeral 10 represents an engine, reference numeral 40 represents a radiator, reference numeral 50 represents a heater core, and reference numeral 60 represents a bypass passage.
  • The electric cooling system of FIG. 1 has an advantage in that a configuration is simple and the number of parts, which are exchanged at the time of changing the mechanical cooling system to the electric cooling system, is minimized, but has a disadvantage in that a function of the electric water pump may not be sufficiently used.
  • Referring to FIGS. 2 and 3, these cooling systems are configured to include the electric water pump 20 and an electronic control valve 70 which may control a passage.
  • In the configuration of FIG. 1, these cooling systems are a cooling system in which the thermostat is replaced with the electronic control valve 70 which may control the passage, and may implement a high temperature control and a fast cooling control and control the heater core 50 and a flow rate of the bypass passage 60, but have a complicated configuration.
  • A factor to complicate the configuration in each cooling system illustrated in FIGS. 1 to 3 is the thermostat and/or the control valve, but the reason why the thermostat and/or the control valve are not removed is that the cooling amount is controlled by the thermostat and/or the control valve.
  • Meanwhile, parts for driving the vehicle, such as an engine, and various heat exchangers such as a radiator, an intercooler, an evaporator, and a condenser are provided inside an engine room of a vehicle is provided, and a heat exchange medium such as a refrigerant flows in the parts and the heat exchange medium inside the heat exchanger and air outside the heat exchanger exchange heat to perform cooling or heat generation.
  • Therefore, to stably operate various heat exchangers within the engine room of the vehicle, external air needs to be smoothly supplied to the inside of the engine room, but when a vehicle is driven at high speed, a large amount of external air is introduced into the engine room at high speed, and thus an air resistance is increased.
  • As a result, the fuel efficiency of the vehicle may be degraded. To solve the above problem, an air flap apparatus, that is, an active air flap (AAF) apparatus, which may improves fuel efficiency by introducing a relatively larger amount of air into the engine room at the time of driving the vehicle at low speed and introducing a relatively smaller amount of air into the engine room at the time of driving the vehicle at high speed, has been used.
  • The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

  • DETAILED DESCRIPTION
  • Reference will now be made in detail to various embodiments of the present invention(s), examples of which are illustrated in the accompanying drawings and described below. While the invention(s) will be described in conjunction with exemplary embodiments, it will be understood that present description is not intended to limit the invention(s) to those exemplary embodiments. On the contrary, the invention(s) is/are intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims.
  • In the specification and claims, unless explicitly described to the contrary, the word “comprise” and variations such as “comprises” or “comprising”, will be understood to imply the inclusion of stated elements but not the exclusion of any other elements. Like reference numerals designate like elements throughout the specification.
  • FIG. 4 is a configuration diagram of a cooling system for a vehicle according to various embodiments of the present invention. The cooling system for a vehicle according to various embodiments of the present invention is a system which controls an introduced air amount and a coolant flow rate passing through a radiator by controlling an air flap apparatus in a vehicle in which the air flap apparatus is equipped.
  • The cooling system for a vehicle according to various embodiments of the present invention includes: an electric water pump 120 configured to circulate coolant; an active air flap (AAF) apparatus 180 configured to actively control an air amount introduced into an engine room of the vehicle; a radiator 140 configured to supply coolant to an engine 110; a cooling fan 145 configured to cool the coolant of the radiator 140; a heater core 150 configured to heat an interior of the vehicle; and a control unit 200 configured to control the electric water pump 120, the air flap apparatus 180, and the fan 145 depending on a driving state and condition of the vehicle.
  • As illustrated in FIG. 4, the radiator 140 is directly connected to the electric water pump 120, without a thermostat and a control valve, which are essential constituent elements in the existing cooling system, being interposed between the radiator 140 and the electric water pump 120. Therefore, the vehicle to which the exemplary embodiment of the present invention is applied does not have the thermostat and the electronic control valve.
  • The engine 110, the electric water pump 120, the air flap apparatus 180, the fan 145, and the heater core 150 may each use the existing apparatuses or similar apparatuses, and therefore the detailed description thereof will be omitted.
  • The control unit 200 receives a signal associated with the active air flap apparatus 180 from an active air flap (AAF) control unit 280 and receives a signal associated with the engine 110 from an engine control unit (ECU) 210, but it should be understood that the scope of the present invention is not limited thereto. Even in a different configuration from the above configuration, the technical spirit of the present invention may be applied to any configuration which may substantially receive the signal associated with the active air flap apparatus 180.
  • The control unit 200 controls the active air flap apparatus 180 to control the cooling air amount passing through the radiator 140 and controls the electric water pump 120 to control the coolant flow rate, thereby keeping the set coolant temperature.
  • That is, the control unit 200 includes at least one microprocessor which is operated by a set program and/or hardware including the microprocessor, in which the set program may be configured of a series of commands performing a control method for a cooling system for a vehicle according to an exemplary embodiment of the present invention, which will be described below.
  • According to various embodiments of the present invention, the control unit 200 is configured alone or may be configured to include the AAF control unit 280 and/or the engine control unit 210 or may be configured to be included in the AAF control unit 280 or the engine control unit 210, in terms of a design.
  • Hereinafter, the control method for a cooling system for a vehicle according to various embodiments of the present invention will be described in detail with reference to the accompanying drawings.
  • FIG. 5 is a flow chart of a control method for a cooling system for a vehicle according to various embodiments of the present invention, and FIG. 6 is a diagram illustrating a connection relationship of the control method for a cooling system for a vehicle according to various embodiments of the present invention.
  • As illustrated, the control unit 200 is, for example, keyed on and thus starts when the vehicle starts to drive, such that the control unit 200 detects an engine output, an engine speed, a vehicle speed, a coolant temperature, or the like which correspond to the vehicle state (S100).
  • The control unit 200 may receive the engine output, the engine speed, the vehicle speed, the coolant temperature, or the like from the engine control unit 210 and the engine control unit 210 generally detects and uses information and/or data as described above, and therefore the detailed description thereof will be omitted.
  • When the engine output, the engine speed, the vehicle speed, the coolant temperature, or the like corresponding to the vehicle state are received from the engine control unit 210, the control unit 200 organically performs controlling an active air flap control (S200), controlling an electric water pump (S300), and controlling a fan (S400) based on the engine output, the engine speed, the vehicle speed, the coolant temperature, or the like, as illustrated in FIG. 6.
  • That is, the control unit 200 organically or integrally or systematically performs controlling the active air flap apparatus 180 depending on the vehicle state (S200); controlling the electric water pump 120 depending on the vehicle state (S300); and controlling the fan 145 for cooling the coolant of the radiator 140 of the cooling system depending on the vehicle state (S400), thereby keeping the temperature of the coolant at the set temperature.
  • Hereinafter, the controlling of the active air flap (S200), the controlling of the electric water pump (S300), and the controlling of the fan (S400) will be described in detail.
  • First, when the AAF is in an operation condition (S210), the control unit 200 controls closing and/or opening operation of the air flap based on the external temperature, the engine output, the vehicle speed, the coolant temperature, and/or the operation states of the electric water pump 120 and the fan 145. The operation condition of the AAF may depend on the existing operation condition.
  • That is, when the air flap is in a closing control condition (S220), the control unit 200 performs an AAF closing control (S250), or otherwise determines whether the AAF is in the opening condition (S230). In step S250, when a stage number of the air flap is configured in plural, for example, when the air flap is configured of two stages, that is, an upper stage and a lower stage, the upper stage control and the lower stage control may be separately performed.
  • In step S230, when the AAF is not in the opening condition, the control unit 200 performs the AAF opening control (S240). Even in step S240, the upper stage control and the lower stage control of the air flap may be separately performed.
  • Further, when the electric water pump 120 is in an operation condition (S310), the control unit 200 controls the electric water pump 120 at the set speed based on the external temperature, the engine output, the vehicle speed, the coolant temperature, and/or the operation states of the air flap apparatus 180 and the fan 145 ((S320), (S330), and (S340)). The operation condition of the electric water pump may depend on the existing operation condition.
  • In addition, when the fan 145 is in an operation condition (S410), the control unit 200 controls the fan 145 to a set speed based on the external temperature, the engine output, the vehicle speed, the coolant temperature, and the operation states of the air flap apparatus 180 and the electric water pump 120. The operation condition of the fan may depend on the existing operation condition.
  • That is, when the fan is in a one-stage operation condition (S420), the control unit 200 controls the speed of the fan 145 at a one stage (S425), when the fan is in a two-stage operation condition (S430), controls the speed of the fan 145 at a two stage (S435), and when the fan is in a non-operation condition, stops the fan 145 (S445).
  • As the result, according to various embodiments of the present invention, it is possible to effectively control the cooling amount without the thermostat and/or a control valve and simplifying the configuration of the cooling system, by controlling the introduced air amount and the coolant flow rate passing through the radiator by controlling the active air flap apparatus in the vehicle in which the active air flap apparatus is equipped.
  • For convenience in explanation and accurate definition in the appended claims, the terms “upper” or “lower”, “inside” or “outside”, and etc. are used to describe features of the exemplary embodiments with reference to the positions of such features as displayed in the figures.
  • The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teachings. The exemplary embodiments were chosen and described in order to explain certain principles of the invention and their practical application, to thereby enable others skilled in the art to make and utilize various exemplary embodiments of the present invention, as well as various alternatives and modifications thereof.
