Description

Technical Field

[0001] The invention relates to the field of vehicle accessories, and in particular to a vehicle window, a method for controlling the vehicle window, and a vehicle comprising the vehicle window. Background Art

[0002] With the development of society and the continuous improvement of people's living standards, cars are no longer just a means of transportation. People have higher requirements for the comfort of the car cabin environment, especially the temperature and air quality in the cabin. At the same time, with the strengthening of people's environmental awareness and the popularization of new energy vehicles, energy saving is also one of the issues that automobile manufacturers need to consider.

[0003] To adjust the cabin environment, current vehicles mainly use air conditioning systems installed in the engine compartment to adjust the environment, or directly open windows for ventilation. However, closing the windows and using the air conditioning system to adjust the temperature and ventilate the vehicle will quickly consume the vehicle's own energy, which will have an adverse effect on the vehicle's endurance, especially for pure electric vehicles. Directly opening windows for ventilation can make the air in the car fresh without consuming additional energy, but current vehicle windows can only achieve air circulation inside and outside the car. When the airflow is too strong, or the airflow temperature is too high or too low, it will make the occupants feel uncomfortable, and it will also cause the temperature of the vehicle cabin to be unbalanced, making it difficult to meet people's demand for vehicle driving comfort.

[0004] Therefore, it is expected to provide a vehicle window that can be used for air conditioning and a method for controlling such a vehicle window, so as to effectively solve the problem that ventilation of the vehicle window easily causes physical discomfort and the indoor environment of the vehicle cabin is difficult to effectively control, so as to achieve the effect of saving energy and improving driving comfort.

[0030] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present invention more clearly understood, the present invention will be further described in detail in conjunction with the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the scope of protection of the present invention, and each embodiment may share the same view or multiple views for description, but all features appearing in the same view cannot be interpreted as features that must be possessed by an embodiment, and multiple views cannot be simply combined and interpreted for one embodiment.

[0031] Before starting the formal description, it should be pointed out that, for the sake of convenience, this article may use directional terms or directional terms for description, and the directional terms or directional terms are relative to the normal use state of the vehicle window. Those skilled in the art can also clearly understand this from the description of the present invention without causing any confusion. In this case, the directional terms and directional terms should not be simply interpreted as the direction or orientation in any state.

[0032] It must also be pointed out that due to the proportional relationship, the limitation of the space of the figure markings, etc., in the following description, it may be necessary to refer to multiple figures at the same time for understanding.

[0033] Figure 1A schematic diagram showing a three-dimensional structure of a vehicle window according to an exemplary embodiment of the present invention; Figure 2 A schematic front view of a vehicle window is shown according to an exemplary embodiment of the present invention.

[0034] like Figure 1 The car window includes a window frame, a heat exchange module and a grille, forming an air-conditioning car window. The car window can adjust the opening angle of the grille, and different opening angles correspond to different sizes of the gaps opened by the grille, so that the air intake of the car window can be controlled, and the temperature of the airflow passing through the car window can also be regulated. Therefore, the car window of the present invention can use the natural wind generated during the driving process of the vehicle to adjust the air quality in the cabin, and can effectively prevent the discomfort caused by excessive airflow, and can also make the temperature of the airflow flowing into the car suitable, thereby improving the cabin environment and enhancing the driving comfort.

[0035] The window frame includes an upper window frame 1, a side window frame 2 and a lower window frame 3, and the upper window frame 1, the side window frame 2 and the lower window frame 3 are connected end to end to form an enclosed area in the middle, such as Figure 1 , the window frame is a side window frame that is approximately triangular. In fact, the vehicle window of the present invention may also be in other shapes, such as a rectangular vehicle window. Accordingly, the window frame may be a rectangular window frame. The upper window frame 1, the side window frame 2 and the lower window frame 3 may all have a hollow structure inside the frame. The side window frame 2 is provided with a liquid inlet 4, which is in fluid communication with the hollow structure inside the frame of the side window frame 2. The upper window frame 1 is provided with a liquid discharge port 5, which is in fluid communication with the hollow structure inside the frame of the upper window frame 1. Figure 1 Preferably, the liquid inlet 4 is arranged at the lower end of the side window frame 2, that is, the side of the side window frame 2 close to the lower window frame 3, so that there is sufficient space to connect the pumping device upstream of the liquid inlet 4, and it does not affect the stability of the door switch. The liquid discharge port 5 is arranged at the lower end of the upper window frame 1, that is, the side of the upper window frame 1 close to the lower window frame 3, so as to collect and recover the coolant. In addition, the liquid inlet 4 is connected to the liquid inlet pipe extending outward, and the liquid discharge port 5 is connected to the liquid discharge pipe extending outward. The liquid inlet pipe extends outward to connect to the coolant pumping device, and the liquid discharge pipe extends outward to connect to the filtering and recovery device. Optionally, the coolant discharged from the liquid discharge pipe 5 can also be processed by heat dissipation cooling or heating, or directly transported back to the liquid inlet pipe by the pumping device, so as to realize the recycling of the coolant. Optionally, the liquid inlet 4 can be arranged at the lower end surface of the side window frame 2, and the liquid outlet 5 can be arranged at the lower end surface of the upper window frame 1 or the end of the lower window frame 3. In addition, the positions of the liquid inlet 4 and the liquid outlet 5 can also be interchanged.

[0036] The upper window frame 1, the side window frame 2 and the lower window frame 3 are configured to have a hollow structure inside the frame, which can not only improve the structural strength of the window frame, but also use the internal hollow structure to form at least a part of the flow path of the coolant to guide the coolant, which can make the heat exchange of the coolant more complete and make the overall structure of the air-conditioned vehicle window compact and occupy less space.

[0037] The heat exchange module includes a plurality of elongated heat exchange tubes 6, the length direction of the heat exchange tubes 6 is transverse to, preferably perpendicular to, the longitudinal extension direction of the side window frame 2, and the plurality of heat exchange tubes 6 are arranged in parallel at equal intervals along the longitudinal extension direction of the side window frame 2. Figure 1 and 2 The right end of the heat exchange tube 6 is connected to the hollow structure inside the side window frame 2, and the left end is connected to the hollow structure inside the upper window frame 1. Figure 3 , shows a schematic diagram of the coolant flow path in the vehicle window, wherein the pumping device transports the coolant to the liquid inlet pipe, and the coolant flows from the liquid inlet 4 into the hollow structure inside the frame of the side window frame 2, and then under the pushing action generated by the pumping device, the coolant flows from the hollow structure inside the frame of the side window frame 2 to each heat exchange tube 6, and after flowing through the heat exchange tube 6, flows out from the other end of the heat exchange tube 6 to the hollow structure inside the frame of the upper window frame 1, and finally the coolant is collected at the drain port 5 through the hollow structure inside the frame of the upper window frame 1 and discharged to the range outside the window frame of the vehicle window. In addition, for a rectangular vehicle window, the right end of the heat exchange tube 6 is connected to the hollow structure inside the frame of the right side window frame 2, and the left end is connected to the hollow structure inside the frame of the left side window frame 2. In this case, the coolant flows into the heat exchange tube 6 from the hollow structure of the right or left side window frame 2, and after flowing through the heat exchange tube 6, it flows into the hollow structure of the side window frame on the opposite side from the other end of the heat exchange tube 6, and finally converges to the drain port 5.

[0038] Preferably, the plurality of heat exchange tubes 6 are arranged in the enclosed area of ​​the window frame, such as Figure 1 The multiple heat exchange tubes 6 arranged in parallel at equal intervals are evenly distributed and can roughly cover the entire enclosed area of ​​the window frame. Therefore, the heat exchange tubes 6 can fully and evenly contact the airflow passing through the car window, which is conducive to achieving efficient and balanced heat exchange.

[0039] Optionally, the heat exchange tube 6 may be a metal tube, or a hose with high heat conductivity, etc.

[0040] The heat exchange module can automatically start to operate when the grille is opened for ventilation, and the heat exchange module of the vehicle window has at least two operating modes, a cooling mode and a heating mode. When the grille is opened for ventilation, when the air temperature outside the vehicle window is too high, the heat exchange module can be automatically controlled to operate in the cooling mode, and when the air temperature outside the vehicle window is too low, the heat exchange module can be automatically controlled to operate in the heating mode. Of course, if the air temperature outside the vehicle window is within an appropriate range, only the grille can be kept open for ventilation without starting the heat exchange module. In the cooling mode, the low-temperature, low-pressure coolant flows into the vehicle window through the liquid inlet pipe from the liquid inlet port 4, and exchanges heat with the air flow passing through the vehicle window through the heat exchange tube 6. At this time, the air flow passing through the vehicle window releases heat and becomes cold wind, while the low-temperature, low-pressure coolant absorbs the heat of the gas flowing through the vehicle window and is collected at the drain port 5 for discharge and recycling; in the heating mode, the high-temperature, high-pressure gaseous coolant flows into the vehicle window through the liquid inlet pipe from the liquid inlet port 4, and exchanges heat with the gas flowing through the vehicle window through the heat exchange tube 6. At this time, the gas flowing through the vehicle window absorbs heat and becomes hot wind, while the high-temperature, high-pressure gaseous coolant releases heat to the gas flowing through the vehicle window and liquefies into liquid coolant, and is collected at the drain port 5 for discharge and recycling.

[0041] Additionally, the heat exchange module also includes a heating module 7, which is connected to the liquid inlet pipe. Specifically, the heating module 7 can be arranged at a position of the liquid inlet pipe near the liquid inlet 4. The heating module 7 has an electric heating wire 7-1 built in. The heating module 7 can be used to heat the coolant before the coolant enters the liquid inlet 4. In particular, when the temperature of the coolant in the heat exchange tube 6 is too low, the heating module 7 can be used to heat the coolant entering the heat exchange tube 6 so that the airflow flowing into the car through the window can be heated more quickly, so that the temperature inside the car can quickly reach the set required temperature inside the car and maintain the temperature inside the car within an appropriate range.

[0042] The grille can rotate and maintain a certain opening angle, so that the window can maintain a corresponding ventilation gap, so that the vehicle window can be opened for ventilation with the help of natural wind when the vehicle is driving, achieving the effect of refreshing the air in the vehicle. Figure 1, multiple grilles are arranged in the enclosed area of ​​the window frame. The grilles are long strips. The length direction of the grilles can be transverse to, preferably perpendicular to, the longitudinal extension direction of the lower window frame 3, and the multiple grilles are arranged in parallel at equal intervals along the longitudinal extension direction of the lower window frame 3. Each grille includes a corresponding grille shaft 8 and a grille plate 9. The grille plate 9 is fixedly connected to the corresponding grille shaft 8. The grille plate 9 follows the rotation of the grille shaft 8. Therefore, by controlling the rotation of the grille shaft 8, the opening angle of the grille plate 9 can be controlled. The opening angle range of the grille plate 9 is 0 degrees to 90 degrees. When the opening angle is 0 degrees, the grille plate is in a closed state. When all the grille plates 9 are in a closed state, the entire window is in a completely closed state, and basically cannot be ventilated with the external environment of the vehicle. Figure 1 The grille shaft 8 and the heat exchange tube 6 are interlaced, preferably arranged perpendicularly to each other, and multiple heat exchange tubes 6 and multiple grilles are interwoven into a grille net, which basically covers the enclosed area of ​​the entire window frame. The grille net can at least partially block the airflow, buffer and reduce the airflow flowing into the car through the window, so that the airflow that finally flows into the car becomes soft, effectively preventing the driver and passengers from feeling uncomfortable due to being directly blown by the strong airflow. When the grille shaft 8 is perpendicular to the longitudinal extension direction of the lower window frame 3, especially when the window is used as a side window of the vehicle, in the scene where the vehicle is driving, the window of the present invention is conducive to effectively buffering and reducing the airflow in the driving direction.

[0043] Figure 4 A schematic diagram of a grille adjustment mechanism according to an exemplary embodiment of the present invention is shown.

[0044] The vehicle window further includes a grille adjustment mechanism, which can realize control and adjustment of the opening angle of the grille plate 9 and the size of the opening gap of the vehicle window. The grille adjustment mechanism can convert the linear motion into the rotation of the grille shaft 8, and at least part of the components of the grille adjustment mechanism can be arranged in the hollow structure inside the window frame. It can be seen that the upper window frame 1, the side window frame 2 and the lower window frame 3 are configured in the form of a hollow structure inside the frame, which can also facilitate the reuse of the space occupied by the window frame itself. The components of the grille adjustment mechanism are installed inside the window frame, which further reduces the space occupied by the air-conditioned vehicle window and makes the overall structure more compact.

[0045] Specifically, the grille adjustment mechanism can adopt a gear rack mechanism, wherein the gear rack 10 is arranged in the hollow structure inside the window frame, and accordingly, the ends of each parallel grille shaft 8 are provided with a corresponding shaft gear 11, and the shaft gear 11 can also be arranged in the hollow structure inside the window frame. Preferably, the gear rack 10 and the shaft gear 11 can be arranged in the hollow structure inside the frame of the lower window frame 3. The gear rack 10 and the shaft gear 11 are meshed with each other to achieve the gear rack transmission cooperation. When the gear rack 10 is driven to perform linear motion, it can drive all the shaft gears 11 to rotate synchronously, thereby driving all the grille shafts 8 to rotate. In this case, the opening angle of the grille plate 9 fixedly connected to the grille shaft 8 also changes synchronously. When the grille shaft 8 rotates and maintains to different angles, the grille plate 9 rotates and maintains at different opening angles.

[0046] Additionally, the grille adjustment mechanism is also equipped with a motor 12. In particular, the motor 12 can be a servo drive motor or a stepper motor. The output end of the motor 12 is connected to a drive gear 13. The drive gear 13 is in transmission cooperation with the rack 10. Under the drive of the motor 12, the drive gear 13 rotates and can drive the rack 10 to move linearly. Additionally or alternatively, the grille adjustment mechanism can also be equipped with a hand wheel (not shown). The output end of the hand wheel is connected to the drive gear 13. When the hand wheel is manually turned, the drive gear 13 rotates and can drive the rack 10 to move linearly. In particular, the side of the rack 10 that cooperates with the rotating shaft gear 11 of the grille is full-toothed, while the side that cooperates with the drive gear 13 is non-full-toothed, so as to reduce the difficulty and cost of processing. In addition, the grille plate 9 can also be directly pulled manually to more conveniently control and adjust the grille plate 9 to the appropriate opening angle.

[0047] Alternatively, the grille adjustment mechanism may also use a transmission mechanism such as a ball screw nut pair to convert the linear motion into the rotation of the grille shaft 8. Similarly, a motor may be used to drive the ball screw to move linearly.

[0048] According to an exemplary embodiment of the present invention, the lower window frame 3 may also have a hollow structure inside the frame body, and the liquid inlet 4 and the liquid discharge port 5 may be arranged on the bottom surface, side surface or end surface of the lower window frame 3. Accordingly, the length direction of the heat exchange tube 6 may be perpendicular to the longitudinal extension direction of the lower window frame 3, and a plurality of heat exchange tubes 6 may be arranged in parallel at equal intervals along the longitudinal extension direction of the lower window frame 3. At this time, one end of the heat exchange tube 6 is connected to the lower window frame 3, and the other end is connected to the upper window frame 1. The coolant flows into the heat exchange tube 6 from the hollow structure of the lower window frame 3, flows through the heat exchange tube 6, and then flows into the hollow structure of the upper window frame 1 from the other end of the heat exchange tube 6, and finally converges to the liquid discharge port 5. In addition, in this case, the grille shaft 8 can still be perpendicular to the longitudinal extension direction of the lower window frame 3, so that the heat exchange tube 6 and the grille are arranged parallel to each other. Of course, the arrangement direction of the grille can also be changed to keep the grille and the heat exchange tube 6 perpendicular to each other, that is, the grille shaft 8 is changed to be arranged perpendicular to the longitudinal extension direction of the side window frame 2. At this time, correspondingly, components such as the rack 10 and the shaft gear 11 in the grille adjustment mechanism are arranged in a hollow structure inside the frame of the lower window frame 3.

[0049] According to an exemplary embodiment of the present invention, Figure 5 , the mutually perpendicular heat exchange tubes 6 and the grille shafts 8 are arranged in an interlaced manner to prevent cross interference. Figure 5 At the intersection of the heat exchange tube 6 and the grille shaft 8, the heat exchange tube 6 has an arched avoidance structure, that is, the protrusion of the heat exchange tube 6 is arched, and the inner concave part of the arch just matches the outer diameter of the grille shaft 8 to allow the grille shaft 8 to pass straight through, thereby ensuring that the fluid flow in the heat exchange tube 6 and the rotation of the grille shaft 8 do not interfere with each other. Alternatively, at the intersection, the grille shaft 8 may also have an arched avoidance structure to allow the heat exchange tube 6 to pass straight through, or both the heat exchange tube 6 and the grille shaft 8 have an arched avoidance structure at the intersection to ensure that the heat exchange tube 6 and the grille shaft 8 do not interfere with each other.

[0050] Additionally or alternatively, the plane formed by multiple parallel arranged heat exchange tubes 6 is called a heat exchange surface, and the plane formed by multiple parallel arranged grille shafts 8 is a grille surface. The heat exchange surface and the grille surface do not overlap in space, thereby ensuring that the flow of coolant in the heat exchange tubes 6 and the rotation of the grille shafts 8 do not interfere with each other and are independent of each other.

[0051] According to an exemplary embodiment of the present invention, in order to provide a good visual effect and maintain good light transmittance, the heat exchange tube 6, grille shaft 8 and grille plate 9 can all be made of highly transparent materials. For example, the grille plate 9 can be made of transparent plastic or glass sheets.

[0052] According to an exemplary embodiment of the present invention, a pressure relief valve 14 may also be provided on the vehicle window. Preferably, the pressure relief valve 14 may be provided on the top of the side window frame 2. When the air pressure in the hollow structure of the window frame is too high, the pressure may be automatically relieved through the pressure relief valve 14 to ensure safety.

[0053] According to an exemplary embodiment of the present invention, the vehicle window is also equipped with a gas flow rate sensor 15. Specifically, the gas flow rate sensor can be set on the window frame, such as the lower window frame 3. The gas flow rate sensor 15 can transmit information to the corresponding control and analysis unit, such as the vehicle-mounted ECU for analysis and judgment, and then the control and analysis unit controls the thermal control management system to automatically adjust the rotation angle of the grille shaft 8 according to the different air flow rates, so as to control the air flow rate flowing into the vehicle through the window to prevent strong air flow from blowing directly and making the occupants feel uncomfortable. Additionally or alternatively, the control and analysis unit can also indirectly judge the air flow rate flowing through the window according to the vehicle speed information, that is, the control and analysis unit can also control the thermal control management system to automatically adjust the rotation angle of the grille shaft 8 according to the vehicle speed information, so as to adjust the opening angle of the control grille plate 9.

[0054] According to an exemplary embodiment of the present invention, corresponding temperature sensors 16 and 17 are arranged near the liquid inlet 4 and the liquid outlet 5, respectively, for real-time detection of the coolant temperature flowing into the window from the liquid inlet 4 and the coolant temperature discharged from the window from the liquid outlet 5. The temperature sensors 16 and 17 can transmit information to the corresponding control and analysis unit, such as the vehicle-mounted ECU for analysis and judgment, and then control the thermal control management system through the control and analysis unit, and automatically adjust the temperature and flow rate of the coolant flowing through the heat exchange tube 6 according to the different temperature sensors, so as to control the temperature of the airflow entering the vehicle through the window, so as to be able to more quickly heat up or cool down the airflow flowing into the vehicle, so that the temperature in the cabin can quickly reach the set vehicle demand temperature and keep the vehicle environment temperature suitable.

[0055] According to an exemplary embodiment of the present invention, Figure 6The window frame is provided with air guide holes 18, air diffusion holes 19 and a fragrance structure, and the fragrance structure includes a fragrance core 20 and a fragrance cover 21. Specifically, the fragrance structure and the air guide holes 18 are arranged at the right end of the lower window frame 3. In particular, the fragrance structure can be arranged in the hollow structure inside the frame body of the lower window frame 3, so as to reuse the space occupied by the lower window frame 3 itself, reduce the additional space occupation, and make the overall structure of the vehicle window more compact. Additionally, a row of air diffusion holes 19 are evenly spaced along the longitudinal direction of the lower window frame 3. Preferably, the row of air diffusion holes 19 are arranged on the upper side or inner side (the side facing the interior of the vehicle) of the lower window frame 3 so that the fragrance can be diffused more fully into the vehicle. The airflow flowing through the vehicle window can carry the fragrance gas molecules emitted by the fragrance core and flow into the inner cavity of the lower window frame 3 through the opening above the fragrance cover 21. Subsequently, the airflow mixed with the fragrance gas molecules is blown into the vehicle through a plurality of through-type air diffusion holes 19 arranged on the inner wall of the lower window frame 3, thereby further improving the air quality in the vehicle and enhancing the driving experience of the occupants.

[0056] Figure 7 A flow chart showing a method for controlling a vehicle window according to an exemplary embodiment of the present invention is shown.

[0057] like Figure 7 , the vehicle window control method performs at least one of the following S1) and S2) operations:

[0058] In operation S1), controlling the opening angle of the grille baffle on the vehicle window; and,

[0059] In operation S2), the flow rate and / or temperature of the coolant flowing through the heat exchange tube on the vehicle window is controlled.

[0060] The window control method of the present invention is actually a control method for air-conditioning windows, which can control and adjust the air flow speed and temperature flowing into the car through the windows. It is not only beneficial to improve the air quality in the car, but also beneficial to meet the requirements of occupants for physical comfort when the windows are ventilated.

[0061] According to an exemplary embodiment of the present invention, in operation S1), operations S11) and S12) are further included.

[0062] In operation S11), the flow rate of the airflow outside the vehicle window is obtained; and,

[0063] In operation S12), the opening angle of the grille baffle on the vehicle window is controlled according to the flow rate of the airflow outside the vehicle window.

[0064] Specifically, the air velocity sensor detects the velocity of the airflow outside the window and uploads it to the vehicle-mounted ECU, which analyzes and compares the velocity information of the airflow, and controls and adjusts the rotation angle of the grille shaft according to the result of the analysis and comparison, thereby controlling the size of the gap of the grille baffle. Specifically, when the airflow velocity is greater than the preset upper velocity limit, the gap of the grille baffle can be controlled to be smaller, and when the airflow velocity is less than the preset lower velocity limit, the gap of the grille baffle can be controlled to be larger.

[0065] According to an exemplary embodiment of the present invention, in operation S2), operations S21) and S22) are further included.

[0066] In operation S21), the coolant temperature at the liquid inlet and the coolant temperature at the liquid outlet are obtained; and

[0067] In operation S22), the flow rate of the coolant flowing inside the heat exchange tube on the vehicle window is controlled according to the difference between the coolant temperature at the liquid inlet and the coolant temperature at the liquid outlet.

[0068] Specifically, the temperature of the coolant at the inlet of the window and the temperature of the coolant at the outlet of the window are detected by the temperature sensor and uploaded to the vehicle ECU, and the vehicle ECU analyzes and compares the obtained coolant temperature at the inlet and the coolant temperature at the outlet, and controls the flow rate and / or temperature of the coolant flowing inside the heat exchange tube on the window. Specifically, when the difference between the coolant temperature at the inlet and the coolant temperature at the outlet is small, for example, the difference is less than the first preset difference, the amount of heat exchange between the coolant flowing inside the heat exchange tube and the airflow flowing through the window may be small, which may indicate that the flow rate of the coolant is too fast, so the flow rate of the coolant can be controlled to be reduced.

[0069] According to an exemplary embodiment of the present invention, in operation S2), operations S23) and S24) are further included.

[0070] In operation S23), the actual temperature inside the vehicle is obtained, and the set required temperature inside the vehicle is obtained; and

[0071] In operation S24), the flow rate of the coolant flowing inside the heat exchange tube on the vehicle window is controlled according to the difference between the actual temperature inside the vehicle and the set required temperature inside the vehicle.

[0072] Specifically, the actual temperature in the vehicle is detected by a temperature sensor, and the set required temperature in the vehicle is obtained and uploaded to the vehicle-mounted ECU. The vehicle-mounted ECU analyzes and compares the actual temperature in the vehicle and the required temperature in the vehicle, and controls the flow rate and / or temperature of the coolant flowing inside the heat exchange tube on the window. Specifically, when the difference between the actual temperature in the vehicle and the required temperature in the vehicle is large, for example, the difference is greater than the second preset difference, the heat exchange amount between the coolant flowing inside the heat exchange tube and the airflow flowing through the window may not meet the demand for rapid cooling or heating. At this time, it may indicate that the flow rate of the coolant is too slow, and the flow rate of the coolant can be controlled to increase.

[0073] Additionally, in the heating mode, in operation S2), operation S25) is further included.

[0074] In operation S25), the temperature of the coolant flowing inside the heat exchange tube on the vehicle window is controlled according to the actual temperature inside the vehicle and the set required temperature inside the vehicle.

[0075] Specifically, the temperature of the coolant flowing in the heat exchange tube on the window can be controlled by increasing or decreasing the power of the heating module. When the actual temperature in the vehicle is lower than the set required temperature in the vehicle, and the difference between the actual temperature in the vehicle and the set required temperature in the vehicle is greater than a third preset difference, the power of the heating module is controlled to be increased; and when the actual temperature in the vehicle is higher than the set required temperature in the vehicle, the heating module can be turned off. Increasing the power of the heating module includes controlling the heating module to enter the heating working state, or controlling the heating module that has entered the heating working state to further increase the heating power, that is, controlling the current passed through the heating wire in the heating module to increase, so as to further increase the temperature of the coolant entering the heat exchange tube, so as to efficiently heat the airflow passing through the window and more quickly increase the temperature in the vehicle cabin.

[0076] According to an exemplary embodiment of the present invention, in operation S2), operations S26) and S27) are further included.

[0077] In operation S26), the temperature of the airflow passing through the vehicle window is obtained, and the temperature of the coolant at the drain port is obtained; and

[0078] In operation S27), the flow rate of the coolant flowing inside the heat exchange tube on the vehicle window is controlled according to the temperature of the air flow passing through the vehicle window and the temperature of the coolant at the drain port.

[0079] Specifically, the temperature of the air flow passing through the window is detected by a temperature sensor and uploaded to the vehicle-mounted ECU. The vehicle-mounted ECU analyzes and compares the acquired temperature of the air flow passing through the window and the coolant temperature at the drain port, and controls the flow rate and / or temperature of the coolant flowing inside the heat exchange tube on the window. Specifically, in the cooling mode, when the coolant temperature at the drain port is high, for example, the coolant temperature at the drain port is close to the temperature of the air flow passing through the window (for example, the temperature difference is within 5 degrees Celsius), or even higher than the temperature of the air flow passing through the window, in this case, it is difficult to achieve a better cooling effect, and there may be a problem of too low heat exchange efficiency between the coolant and the air flow, indicating that the flow rate of the coolant is too slow, and the coolant flow rate can be controlled to increase; in the heating mode, when the coolant temperature at the drain port is low, for example, the coolant temperature at the drain port is close to the temperature of the air flow passing through the window (for example, the temperature difference is within 5 degrees Celsius), or even lower than the temperature of the air flow passing through the window, it indicates that the heat exchange efficiency is too low. In this case, it is difficult to achieve a better heating effect, and there may be a problem of too low heat exchange efficiency between the coolant and the air flow, indicating that the flow rate of the coolant is too slow, and the coolant flow rate can be controlled to increase.

[0080] Additionally, in the heating mode, in operation S2), operation S28) is further included.

[0081] In operation S28), the temperature of the coolant flowing inside the heat exchange tube on the vehicle window is controlled according to the difference between the temperature of the airflow flowing through the vehicle window and the temperature of the coolant at the drain port.

[0082] Specifically, controlling the temperature of the coolant flowing in the heat exchange tube on the window can be achieved by controlling to increase or decrease the power of the heating module. In the heating mode, when the coolant temperature at the drain port is low, for example, the coolant temperature at the drain port is close to the temperature of the air flow passing through the window (for example, the temperature difference is within 5 degrees Celsius), or even lower than the temperature of the air flow passing through the window, the power of the heating module is controlled to be increased.
