[0038] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0039] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0040] In the prior art, the wind pressure is reduced mainly by increasing the size of the pressure relief valve. However, the method in the prior art requires changes to the vehicle hardware, which increases the cost, and increasing the pressure relief valve will reduce work efficiency, reduce the airtightness of the entire vehicle, and affect the user experience.

[0041] The control method of the vehicle air conditioner provided in the present application obtains the operating information of the vehicle air conditioner, wherein the vehicle air conditioner is currently operating in an external circulation mode, or the vehicle air conditioner is currently operating in an external circulation mode and an internal circulation mode, and obtains the status information of the opening and closing parts of the vehicle where the vehicle air conditioner is located, the opening and closing part status information is used to characterize the opening and closing states of the opening and closing parts of the vehicle, and the opening and closing states include an open state and a closed state. When the operating information meets the preset conditions and there is at least one opening and closing part in the open state, the air volume ratio of the external circulation mode of the vehicle air conditioner is reduced. By limiting the vehicle air conditioner to currently operating in the external circulation mode, or operating in the external circulation mode and the internal circulation mode, the determination of the need to reduce the external circulation mode of the vehicle air conditioner can be improved. The efficiency of the air volume ratio of the circulation mode can be improved, thereby improving the user's car experience. Specifically, on the basis of limiting the vehicle air-conditioning to currently operate in the external circulation mode, or operating in the external circulation mode and the internal circulation mode, by limiting the operating information to meet the preset conditions and at least one opening and closing component is in the open state, it is possible to accurately and efficiently determine the situation where the air volume ratio of the external circulation mode of the vehicle air-conditioning needs to be reduced, thereby improving the efficiency and accuracy of the control of the vehicle air-conditioning, and further improving the user's car experience. Specifically, the control process of the vehicle air-conditioning provided in the present application does not require adjustment of the hardware of the vehicle air-conditioning, thereby reducing costs. Based on the above description, the present application achieves the effect of reducing costs and improving user experience.

[0042] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0043] Figure 1 The process diagram of the vehicle air conditioner control method provided in this application is as follows: Figure 1 ,like Figure 1 As shown, the method includes:

[0044] Step S101: Acquire operation information of the vehicle air conditioner, wherein the vehicle air conditioner is currently operating in an external circulation mode, or the vehicle air conditioner is currently operating in an external circulation mode and an internal circulation mode.

[0045] Among them, the external circulation mode refers to the vehicle air conditioning system sucking the air outside the car into the car, and after heating, cooling or filtering, it is discharged outside the car. This mode realizes the air exchange between the inside and outside of the car. The internal circulation mode refers to the vehicle air conditioning system circulating the air inside the car in a closed state, and after heating, cooling or filtering, it is sent back into the car. This mode does not introduce air from outside the car. In this application, the vehicle air conditioner is currently operating in the external circulation mode, which means that the proportion of time occupied by the external circulation mode of the vehicle air conditioner or the proportion of air circulation is 100%. Among them, the vehicle air conditioner is currently operating in the external circulation mode and the internal circulation mode, which means that the proportion of time occupied by the external circulation mode of the vehicle air conditioner or the proportion of air circulation is greater than zero and less than 100%.

[0046] Specifically, based on the above description, if the vehicle air conditioner is currently operating in the external circulation mode, or the vehicle air conditioner is currently operating in the external circulation mode and the internal circulation mode, the vehicle air conditioner will suck the air outside the car into the car, thereby causing the wind pressure to increase and affecting the user experience. Therefore, the control method of the vehicle air conditioner provided in this application can be implemented.

[0047] Specifically, if the vehicle air conditioner is currently operating in the external circulation mode, or the vehicle air conditioner is currently operating in the external circulation mode and the internal circulation mode, the operation information of the vehicle air conditioner can be obtained, wherein the operation information is used to characterize the external circulation air volume of the vehicle air conditioner per unit time.

[0048] Among them, this application does not limit the operating information of the vehicle air conditioner, and any information that can characterize the external circulation air volume of the vehicle air conditioner per unit time can be used as the operating information provided by this application. Optionally, the operating information of the vehicle air conditioner includes but is not limited to wind speed gear parameters and external circulation ratio parameters.

[0049] Step S102: acquiring the status information of the opening and closing parts of the vehicle where the vehicle air conditioner is located. The status information of the opening and closing parts is used to represent the opening and closing status of the opening and closing parts of the vehicle. The opening and closing status includes an open state and a closed state.

[0050] Specifically, the status information of the opening and closing parts of the vehicle where the vehicle air conditioner is located can be obtained, wherein the opening and closing parts status information is used to characterize the opening and closing states of the opening and closing parts of the vehicle, and the opening and closing states include an open state and a closed state. The opening and closing parts are components that can be opened and closed in the vehicle where the vehicle air conditioner is located, wherein the present application does not limit the opening and closing parts, and any components that can be opened and closed in the vehicle where the vehicle air conditioner is located can be used as the opening and closing parts provided by the present application, and optionally, the opening and closing parts include but are not limited to at least one of the components such as windows, back doors, and doors.

[0051] Step S103: when the operation information meets the preset conditions and at least one opening and closing member is in the open state, the air volume ratio of the external circulation mode of the vehicle air conditioner is reduced.

[0052] Specifically, when the operation information obtained in step S101 meets the preset conditions and the opening and closing state information of the vehicle in which the vehicle air conditioner is located obtained in step S102 indicates that at least one opening and closing member is in an open state, the air volume ratio of the external circulation mode of the vehicle air conditioner is reduced.

[0053] The preset condition is a preset condition that makes the external circulation air volume of the vehicle air conditioner in a unit time greater than a preset air volume threshold. The preset condition corresponds to the operation information. When the operation information is different, the corresponding preset condition is also different.

[0054] Specifically, when the operating information meets the preset conditions described above, if there is at least one opening and closing component in an open state, then when the opening and closing component is closed, the high wind pressure will affect the user's experience of closing the closing component, thereby affecting the user's car experience.

[0055] Specifically, when the operating information meets the preset conditions described above, if all opening and closing parts are in a closed state, the user does not need to close the closing parts, so the higher wind pressure will not affect the user's car experience.

[0056] The control method of the vehicle air conditioner provided in the embodiment of the present application obtains the operating information of the vehicle air conditioner, wherein the vehicle air conditioner is currently operating in an external circulation mode, or the vehicle air conditioner is currently operating in an external circulation mode and an internal circulation mode, and obtains the status information of the opening and closing parts of the vehicle where the vehicle air conditioner is located, the opening and closing part status information is used to characterize the opening and closing states of the opening and closing parts of the vehicle, and the opening and closing states include an open state and a closed state. When the operating information meets the preset conditions and there is at least one opening and closing part in the open state, the air volume ratio of the external circulation mode of the vehicle air conditioner is reduced. By limiting the vehicle air conditioner to currently operating in the external circulation mode, or operating in the external circulation mode and the internal circulation mode, the determination of the need to reduce the air volume of the vehicle air conditioner can be improved. The efficiency of the air volume ratio of the external circulation mode can be improved, thereby improving the user's car experience. Specifically, on the basis of limiting the vehicle air-conditioning to currently operate in the external circulation mode, or operating in the external circulation mode and the internal circulation mode, by limiting the operating information to meet the preset conditions and at least one opening and closing component is in the open state, it is possible to accurately and efficiently determine the situation where the air volume ratio of the external circulation mode of the vehicle air-conditioning needs to be reduced, thereby improving the efficiency and accuracy of the control of the vehicle air-conditioning, and further improving the user's car experience. Specifically, the control process of the vehicle air-conditioning provided in the present application does not require adjustment of the hardware of the vehicle air-conditioning, thereby reducing the cost. Based on the above description, the present application achieves the effect of reducing costs and improving user experience.

[0057] In a possible embodiment, if the vehicle where the vehicle air conditioner is located is a frameless door vehicle, the opening and closing component status information of the vehicle where the vehicle air conditioner is located indicates the opening and closing status of each window of the vehicle where the vehicle air conditioner is located, and the opening and closing status of the back door of the vehicle where the vehicle air conditioner is located.

[0058] Among them, frameless door vehicles refer to vehicles with frameless doors. Frameless doors are doors with frameless design. The most notable feature of frameless doors is that they have no frame. The window glass fits tightly with the body, presenting a smooth, elegant and unique visual effect. When the frameless door is opened, the window glass will automatically drop a little so that the door can be opened smoothly. After the frameless door is closed, the window glass will automatically rise, enter the pre-set glass groove, and get stuck in the sealing strip to achieve seamless fit and sealing effect.

[0059] Among them, the description of the opening and closing parts can refer to the description in step S102, which will not be repeated here. Specifically, based on the above description of the frameless door, when the vehicle where the car air conditioner is located is a frameless door vehicle, if the opening and closing state of the frameless door is an open state, the opening and closing state of the corresponding window is also an open state, and if the opening and closing state of the frameless door is a closed state, the opening and closing state of the corresponding window can be an open state or a closed state. Therefore, when the vehicle where the car air conditioner is located is a frameless door vehicle, whether the door is open or the window is open, the window is in an open state. Among them, based on the description in step S103, if it is to be determined that the air volume ratio of the external circulation mode of the vehicle air-conditioning needs to be reduced, one of the prerequisites is to determine that at least one opening and closing component of the vehicle where the vehicle air-conditioning is located is in an open state. Therefore, if the vehicle where the vehicle air-conditioning is located is a frameless door vehicle, there is no need to repeatedly judge the opening and closing states of the windows and the doors, and it is only necessary to judge the opening and closing states of the windows. That is, if the vehicle where the vehicle air-conditioning is located is a frameless door vehicle, the opening and closing component status information of the vehicle where the vehicle air-conditioning is located can indicate the opening and closing states of each window of the vehicle where the vehicle air-conditioning is located, and the opening and closing states of the back door of the vehicle where the vehicle air-conditioning is located.

[0060] Specifically, if the vehicle where the on-board air conditioner is located is a frameless door vehicle, the air volume ratio of the external circulation mode of the on-board air conditioner can be reduced when the operation information meets the preset conditions and the opening and closing state of at least one window and / or back door is in the open state. Among them, when the vehicle where the on-board air conditioner is located is a frameless door vehicle, and the operation information meets the preset conditions, that is, when the wind pressure in the car is relatively large, if the opening and closing state of the window is in the open state because the window is open, it will cause the user to close the window. The window will be pushed outward, resulting in the problem that the window cannot be smoothly slotted, thereby affecting the user's car experience. Among them, when the vehicle where the on-board air conditioner is located is a frameless door vehicle, and the operation information meets the preset conditions, that is, when the wind pressure in the car is relatively large, if the opening and closing state of the window is in the open state because the door is open, it will cause the user to close the door. The door will be pushed outward, and it will take more force to close the door, thereby affecting the user's car experience. Among them, when the vehicle where the car air conditioner is located is a frameless door vehicle and the operating information meets the preset conditions, that is, when the wind pressure in the car is large, if the opening and closing state of the tailgate is in the open state, the tailgate will be pushed outward when the user closes the tailgate, and greater force will be required to close the tailgate, thus affecting the user's car experience.

[0061] Among them, if the vehicle where the car air conditioner is located is a frameless door vehicle, when determining whether it is necessary to reduce the air volume ratio of the external circulation mode of the car air conditioner, it is only necessary to determine it based on the opening and closing status of the windows and the back door. This can improve the efficiency of the determination process, thereby improving the control efficiency of the car air conditioner and further improving the user's car experience.

[0062] In a possible embodiment, if the vehicle where the vehicle air conditioner is located is a vehicle with frame doors, the opening and closing component status information of the vehicle where the vehicle air conditioner is located indicates the opening and closing status of each door of the vehicle where the vehicle air conditioner is located, and the opening and closing status of the back door of the vehicle where the vehicle air conditioner is located.

[0063] Among them, vehicles with framed doors refer to vehicles with framed doors. Framed doors are doors with framed design. Framed doors use door frames to fix doors and windows. This design makes the door structure more solid and improves the overall rigidity and stability of the vehicle. Compared with frameless doors, framed doors are more traditional and simple in design, usually with metal frames, giving people a sense of stability and heaviness. Framed doors are more solid in door structure and can provide effective protection for passengers in collision accidents. At the same time, the anti-pinch design of the door edge also further improves the safety of passengers.

[0064] Among them, in the framed door, the door frame is provided with a track for the window to slide, that is, a glass groove. Therefore, when the window is closed, no matter how large the wind pressure is in the vehicle where the vehicle air conditioner is located, the window will not be unable to enter the groove smoothly, so the impact on the user's car experience is small. Among them, based on the description in step S103, if it is necessary to determine the air volume ratio of the external circulation mode of the vehicle air conditioner that needs to be reduced, one of the prerequisites is to determine that at least one of the opening and closing parts of the vehicle where the vehicle air conditioner is located is in an open state. Therefore, if the vehicle where the vehicle air conditioner is located is a vehicle with a framed door, there is no need to judge the opening and closing state of the window, that is, if the vehicle where the vehicle air conditioner is located is a vehicle without a framed door, the opening and closing part status information of the vehicle where the vehicle air conditioner is located can indicate the opening and closing state of each door of the vehicle where the vehicle air conditioner is located, and the opening and closing state of the back door of the vehicle where the vehicle air conditioner is located.

[0065] Specifically, if the vehicle in which the car air conditioner is located is a vehicle with frame doors, the air volume ratio of the external circulation mode of the car air conditioner can be reduced when the operating information meets the preset conditions and the opening and closing state of at least one door and / or the back door is in the open state.

[0066] Among them, if the vehicle where the car air conditioner is located is a vehicle with frame doors, when determining whether it is necessary to reduce the air volume ratio of the external circulation mode of the car air conditioner, it is only necessary to determine it based on the opening and closing status of the door and the back door. The efficiency of the determination process can be improved, thereby improving the control efficiency of the car air conditioner and further improving the user's car experience.

[0067] In a possible embodiment, the operation information includes a wind speed level parameter and an external circulation ratio parameter.

[0068] Among them, the wind speed gear parameter is a parameter indicating the gear of the wind speed at the air outlet of the vehicle air conditioner, and the external circulation ratio parameter indicates the ratio of the outside air inhaled by the vehicle air conditioner in the external circulation mode, or in the external circulation mode and the internal circulation mode. This ratio is usually expressed as a percentage.

[0069] Among them, if the operating information includes wind speed gear parameters and external circulation ratio parameters, the process of determining whether the operating information meets the preset conditions can be: if the external circulation air volume of the vehicle air conditioner per unit time calculated according to the wind speed gear parameters and external circulation ratio parameters included in the operating information is greater than the preset air volume threshold, then it is determined that the operating information meets the preset conditions.

[0070] The preset air volume threshold is the threshold of the external circulation air volume of the vehicle air conditioner in a unit time. If the vehicle model of the vehicle air conditioner is different, the pre-calibrated preset air volume threshold is also different. For example, if the vehicle model indicates that the interior space is larger, the pre-calibrated preset air volume threshold is also larger. Conversely, if the vehicle model indicates that the interior space is smaller, the pre-calibrated preset air volume threshold is also smaller.

[0071] Among them, this application does not limit the process of calculating the external circulation air volume of the vehicle air conditioner per unit time according to the wind speed gear parameter and the external circulation ratio parameter included in the operation information. Optionally, the air outlet area can be determined first, and then the wind speed can be determined according to the wind speed gear, and then the theoretical air volume can be calculated, and finally the external circulation ratio can be used to calculate the external circulation air volume.

[0072] Among them, the air outlet area is the ventilation area of ​​the vehicle air conditioning air outlet. This area may vary depending on the vehicle model and the design of the vehicle air conditioning system. Assume that the known air outlet area is F square meters (m²). Among them, in the process of determining the wind speed according to the wind speed gear, the wind speed corresponding to the wind speed gear can be queried from the mapping table of the gear and wind speed of the vehicle air conditioner. Assume that the wind speed is V meters per second (m / s). Among them, in the process of calculating the theoretical air volume, the air volume calculation formula L = 3600 × F × V can be used for calculation, where L represents the air volume, and the unit is cubic meters per hour (m³ / h). This formula is based on the product of wind speed and air outlet area, and takes into account the time factor (3600 seconds is one hour). Among them, in the process of calculating the external circulation air volume using the external circulation ratio, since the external circulation ratio parameter represents the proportion of external air inhaled by the air conditioning system in the external circulation mode, it is necessary to multiply the theoretical air volume by this ratio to obtain the external circulation air volume. Assuming that the external circulation ratio is P (%), the external circulation air volume can be L _out = L × (P / 100).

[0073] Among them, if the external circulation air volume of the vehicle air conditioner per unit time calculated according to the wind speed gear parameter and the external circulation ratio parameter included in the operating information is greater than the preset air volume threshold, it is determined that the operating information meets the preset conditions, and the process of reducing the air volume ratio of the external circulation mode of the vehicle air conditioner described in step S103 may include reducing the wind speed gear indicated by the wind speed gear parameter and / or reducing the external circulation ratio indicated by the external circulation ratio parameter, so that the external circulation air volume of the vehicle air conditioner per unit time calculated according to the adjusted wind speed gear parameter and the external circulation ratio parameter is less than or equal to the preset air volume threshold.

[0074] In a possible embodiment, the operation information includes wind speed gear parameters and external circulation ratio parameters. For the description of wind speed gear parameters and external circulation ratio parameters, reference can be made to the description in the above embodiment, which will not be repeated here.

[0075] Wherein, if the operation information includes wind speed gear parameters and external circulation ratio parameters, the process of determining whether the operation information meets the preset conditions can also be: if the wind speed gear parameters and external circulation ratio parameters included in the operation information meet the preset corresponding relationship, then determine that the operation information meets the preset conditions. Wherein, the preset corresponding relationship is the preset corresponding relationship between the preset wind speed gear parameters and the external circulation ratio parameters. The preset corresponding relationship makes the external circulation air volume of the vehicle air conditioner in unit time greater than the preset air volume threshold.

[0076] Among them, this application does not limit the preset corresponding relationship. Any corresponding relationship between the preset wind speed gear parameter and the external circulation ratio parameter that makes the external circulation air volume of the vehicle air conditioner in a unit time greater than the preset air volume threshold can be used as the preset corresponding relationship provided by this application. Among them, the preset corresponding relationship corresponds to the model of the vehicle where the vehicle air conditioner is located and the model of the vehicle air conditioner. Therefore, it can be pre-calibrated according to the model of the vehicle where the vehicle air conditioner is located and the model of the vehicle air conditioner.

[0077] Optionally, the preset corresponding relationship can be: when the wind speed gear parameter indicates that the wind speed gear is the fourth gear, the external circulation ratio parameter indicates that the external circulation ratio is greater than 60%; when the wind speed gear parameter indicates that the wind speed gear is the fifth gear, the external circulation ratio parameter indicates that the external circulation ratio is greater than 50%; when the wind speed gear parameter indicates that the wind speed gear is the sixth gear, the external circulation ratio parameter indicates that the external circulation ratio is greater than 40%; when the wind speed gear parameter indicates that the wind speed gear is the seventh gear, the external circulation ratio parameter indicates that the external circulation ratio is greater than 30%.

[0078] Among them, if the wind speed gear parameter and the external circulation ratio parameter included in the operating information meet the preset corresponding relationship, it is determined that the operating information meets the preset conditions, and the process of reducing the air volume ratio of the external circulation mode of the vehicle air conditioner described in step S103 may include reducing the wind speed gear indicated by the wind speed gear parameter and / or reducing the external circulation ratio indicated by the external circulation ratio parameter, so that the adjusted wind speed gear parameter and the external circulation ratio parameter meet the preset corresponding relationship.

[0079] Figure 2 The control process of the vehicle air conditioner provided in this application is shown in FIG. Figure 2 ,like Figure 2 As shown, in this embodiment Figure 1 Based on the embodiment, another method for controlling a vehicle air conditioner is described in detail.

[0080] Step S201: Acquire operation information of the vehicle air conditioner, wherein the vehicle air conditioner is currently operating in an external circulation mode, or the vehicle air conditioner is currently operating in an external circulation mode and an internal circulation mode.

[0081] The operation information is used to characterize the external circulation air volume of the vehicle air conditioner per unit time.

[0082] Specifically, for the detailed description of this step, reference may be made to the description of step S101, which will not be repeated here.

[0083] Step S202: acquiring the status information of the opening and closing parts of the vehicle where the vehicle air conditioner is located. The status information of the opening and closing parts is used to represent the opening and closing status of the opening and closing parts of the vehicle. The opening and closing status includes an open state and a closed state.

[0084] Specifically, for the detailed description of this step, reference may be made to the description in step S102, which will not be repeated here.

[0085] Step S203: when the operation information meets the preset conditions and at least one opening and closing member is in an open state, determine the target external circulation ratio parameter according to the wind speed level parameter included in the operation information.

[0086] The operation information includes wind speed gear parameters and external circulation ratio parameters.

[0087] Among them, the description of the preset conditions, wind speed gear parameters, and external circulation ratio parameters can refer to the description in the above embodiment and will not be repeated here.

[0088] Specifically, when the operation information meets the preset conditions and at least one opening and closing member is in the open state, the target external circulation ratio parameter can be determined according to the wind speed gear parameter included in the operation information. The target external circulation ratio parameter is the external circulation ratio parameter of the vehicle air conditioner, which is to be adjusted to when the operation information meets the preset conditions and at least one opening and closing member is in the open state, so as to reduce the parameter value of the air volume ratio of the external circulation mode of the vehicle air conditioner.

[0089] Among them, the process of determining the target external circulation ratio parameter according to the wind speed gear parameter included in the operation information corresponds to the process of determining whether the operation information meets the preset conditions.

[0090] For example, if the wind speed gear parameter and the external circulation ratio parameter included in the operating information meet the preset corresponding relationship, it is determined that the operating information meets the preset conditions, and the preset corresponding relationship is as described in the above embodiment. Then, according to the wind speed gear parameter included in the operating information, the process of determining the target external circulation ratio parameter can be: when the wind speed gear parameter indicates that the wind speed gear is the fourth gear, the target external circulation ratio parameter is 60% or less than 60% of the preset value; when the wind speed gear parameter indicates that the wind speed gear is the fifth gear, the target external circulation ratio parameter is 50% or less than 50% of the preset value; when the wind speed gear parameter indicates that the wind speed gear is the sixth gear, the target external circulation ratio parameter is 40% or less than 40% of the preset value; when the wind speed gear parameter indicates that the wind speed gear is the seventh gear, the target external circulation ratio parameter is 30% or less than 30% of the preset value.

[0091] For example, if the external circulation air volume of the vehicle air conditioner per unit time calculated according to the wind speed gear parameter and the external circulation ratio parameter included in the operating information is greater than the preset air volume threshold, it is determined that the operating information meets the preset conditions. Then, according to the wind speed gear parameter included in the operating information, the process of determining the target external circulation ratio parameter can be as follows: according to the wind speed gear parameter included in the operating information, the external circulation ratio parameter that makes the calculated external circulation air volume of the vehicle air conditioner per unit time less than or equal to the preset air volume threshold is determined as the target external circulation ratio parameter.

[0092] Optionally, when the operation information meets the preset conditions and at least one switch is in the open state, the target wind speed gear parameter can also be determined according to the external circulation ratio parameter included in the operation information. The target wind speed gear parameter is the wind speed gear parameter of the vehicle air conditioner, which is to be adjusted to the parameter value to reduce the air volume ratio of the external circulation mode of the vehicle air conditioner when the operation information meets the preset conditions and at least one switch is in the open state.

[0093] Among them, the process of determining the target wind speed gear parameter according to the external circulation ratio parameter included in the operation information may correspond to the process of determining whether the operation information meets the preset conditions.

[0094] For example, if the wind speed gear parameter and the external circulation ratio parameter included in the operating information meet the preset corresponding relationship, it is determined that the operating information meets the preset conditions, and the preset corresponding relationship is as described in the above embodiment. Then, according to the external circulation ratio parameter included in the operating information, the process of determining the target wind speed gear parameter can be: when the external circulation ratio parameter indicates that the external circulation ratio is greater than 60%, the wind speed gear indicated by the target wind speed gear parameter is the third gear; when the external circulation ratio parameter indicates that the external circulation ratio is greater than 50% and less than or equal to 60%, the wind speed gear indicated by the target wind speed gear parameter is the fourth gear; when the external circulation ratio parameter indicates that the external circulation ratio is greater than 40% and less than or equal to 50%, the wind speed gear indicated by the target wind speed gear parameter is the fifth gear; when the external circulation ratio parameter indicates that the external circulation ratio is greater than 30% and less than or equal to 40%, the wind speed gear indicated by the target wind speed gear parameter is the sixth gear.

[0095] For example, if the external circulation air volume of the vehicle air conditioner per unit time calculated according to the wind speed gear parameter and the external circulation ratio parameter included in the operating information is greater than the preset air volume threshold, it is determined that the operating information meets the preset conditions. Then, according to the external circulation ratio parameter included in the operating information, the process of determining the target wind speed gear parameter can be as follows: according to the external circulation ratio parameter included in the operating information, the wind speed gear parameter that makes the calculated external circulation air volume of the vehicle air conditioner per unit time less than or equal to the preset air volume threshold is determined as the target wind speed gear parameter.

[0096] Step S204: the external circulation ratio parameter included in the control operation information is adjusted to the target external circulation ratio parameter to reduce the air volume ratio of the external circulation mode of the vehicle air conditioner.

[0097] Specifically, after determining the target external circulation ratio parameter, the external circulation ratio parameter included in the operation information can be controlled to be adjusted to the target external circulation ratio parameter to reduce the air volume ratio of the external circulation mode of the vehicle air conditioner.

[0098] Optionally, if the operating information meets the preset conditions and at least one opening and closing component is in the open state, the target wind speed gear parameter is determined based on the external circulation ratio parameter included in the operating information, then the wind speed gear parameter included in the operating information can be controlled to be adjusted to the target wind speed gear parameter to reduce the air volume ratio of the external circulation mode of the vehicle air conditioner.

[0099] Step S205: If it is determined that the acquired opening and closing member status information indicates that all the opening and closing members are in a closed state, the air volume ratio of the external circulation mode of the vehicle air conditioner is restored.

[0100] Specifically, after reducing the air volume ratio of the external circulation mode of the vehicle air conditioner, if it is determined that the acquired opening and closing component status information indicates that all the opening and closing components are in a closed state, that is, each of the opening and closing components in at least one open state in the vehicle where the vehicle air conditioner is located as determined in step S103 has completed the closing process, then the air volume ratio of the external circulation mode of the vehicle air conditioner is restored to ensure the heating or heat supply needs of the vehicle air conditioner.

[0101] Among them, the process of restoring the air volume ratio of the external circulation mode of the vehicle air conditioner can correspond to the process of reducing the air volume ratio of the external circulation mode of the vehicle air conditioner described in step S203 and step S204, and restore the adjusted parameters to the parameters before adjustment, for example, restore the target external circulation ratio parameters to the external circulation ratio parameters before adjustment, for example, restore the target wind speed gear parameters to the wind speed gear parameters before adjustment.

[0102] The control method of the vehicle air conditioner provided in the embodiment of the present application is Figure 1 On the basis of the illustrated embodiment, when the operation information meets the preset conditions and at least one opening and closing component is in the open state, the target external circulation ratio parameter is determined according to the wind speed gear parameter included in the operation information, and the external circulation ratio parameter included in the operation information is controlled to be adjusted to the target external circulation ratio parameter to reduce the air volume ratio of the external circulation mode of the vehicle air conditioner. The process of reducing the air volume ratio of the external circulation mode of the vehicle air conditioner is completed when the operation information meets the preset conditions and at least one opening and closing component is in the open state, wherein the air volume ratio of the external circulation mode of the air conditioner can be accurately and simply reduced by the determined target external circulation ratio, thereby improving the user's car experience. wherein, after reducing the air volume ratio of the external circulation mode of the vehicle air conditioner, when it is determined that the acquired opening and closing component status information indicates that all the opening and closing components are in the closed state, the air volume ratio of the external circulation mode of the vehicle air conditioner is restored, which can effectively ensure the heating or heat supply demand of the vehicle air conditioner, thereby improving the user's car experience.
