DETAILED DESCRIPTION

[0018] The following is a description of exemplary embodiments of the present application in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0019] As mentioned in the background technology, the existing technology has the problem that the air conditioning system cannot be automatically controlled to obtain a better air environment. In this regard, the present application uses the method of adjusting the opening angle of the air conditioning damper based on the height of the front vehicle, the width of the front vehicle, the number of the front vehicles, the distance between the vehicle and the front vehicle, the speed of the front vehicle and the initial angle of the air conditioning damper, so as to realize the automatic control of the internal and external circulation of the air conditioning system to improve the air quality in the vehicle. The present application is further described in detail below in conjunction with the embodiments.

[0020] Example 1 Figure 1 It is a flow chart of an air conditioning internal and external circulation control method provided in this embodiment. The method can be executed by an air conditioning internal and external circulation control device. The device can be composed of software and / or hardware and is generally integrated in an electronic device. The electronic device can be an air conditioning controller or an electronic control system. For ease of understanding, each step in the control method of this embodiment takes the electronic control system as the execution body.

[0021] like Figure 1 As shown, this embodiment provides an air conditioning internal and external circulation control method, comprising the following steps: S110. In response to the air conditioning internal and external circulation control function being started, determining a leading vehicle influence factor according to a leading vehicle height and a leading vehicle width; the leading vehicle influence factor is used to characterize the influence of the leading vehicle height and the leading vehicle width on the air quality of the rear vehicle.

[0022] The height and width of the front vehicle are different, and the exhaust gas, dust and other effects generated during driving are different; the higher the height and the wider the width, the greater the impact, and the greater the impact on the air quality of the rear vehicle. Therefore, this step first determines the front vehicle impact factor based on the height and width of the front vehicle, so as to more accurately control the opening angle of the air conditioning damper.

[0023] The "front vehicle" refers to the vehicle directly in front of or to the side of the vehicle that uses the air conditioning internal and external circulation control method. The height and width of the front vehicle can be identified by the laser radar or camera of the vehicle. The specific identification method is not limited in this embodiment, and any achievable identification method in the art can be used. For example, the height and width of the front vehicle in the image can be calculated by using an image fusion algorithm based on the image collected by the camera in front of the vehicle.

[0024] In an optional implementation, determining the leading vehicle influence factor according to the leading vehicle height and the leading vehicle width includes: Obtaining a first mapping relationship between the height of the front vehicle and a first influencing factor, and a second mapping relationship between the width of the front vehicle and a second influencing factor; the first influencing factor is used to characterize the influence of the height of the front vehicle on the air quality of the rear vehicle, and the second influencing factor is used to characterize the influence of the width of the front vehicle on the air quality of the rear vehicle; Determining a first influencing factor according to the first mapping relationship and the height of the preceding vehicle; Determining a second influencing factor according to the second mapping relationship and the width of the preceding vehicle; The preceding vehicle impact factor is determined according to the first impact factor and the second impact factor.

[0025] This embodiment introduces the first mapping relationship and the second mapping relationship to respectively determine the first influencing factor and the second influencing factor, and then determine the preceding vehicle influencing factor, which is simple and feasible. The first mapping relationship and the second mapping relationship can be obtained by calibration. Select a typical vehicle height, such as 0~3m, build a vehicle model, and carry out simulation tests with vehicle models of different heights under the same test conditions, such as the same test site or the same test road, record the duration of dust, and then select the degree of dust according to the duration of dust; the range of the degree of dust is 0~2, and the larger the value, the greater the degree of dust; for example, if the duration of dust is 5s, select the degree of dust 1, and if the duration of dust is 30s, select the degree of dust 2, and the intermediate time is determined according to the interpolation method; after the degree of dust is determined, the above-mentioned first mapping relationship can be established. Similarly, a typical vehicle width is selected, such as 0~2m, and a vehicle model is built. Under the same test conditions, such as the same test site or the same test road, simulation tests are carried out using vehicle models of different widths, and the dust duration is recorded. The dust degree is then selected based on the dust duration. The dust degree ranges from 0 to 2, and the larger the value, the greater the dust degree. For example, if the dust duration is 5s, select dust degree 1, and if the dust duration is 30s, select dust degree 2. The intermediate time is determined by interpolation. After the dust degree is determined, the above-mentioned second mapping relationship can be established.

[0026] Table 1 is an example of a first mapping relationship, and Table 2 is an example of a second mapping relationship.

[0027] Table 1

[0028] Table 2

[0029] Optionally, the leading vehicle influence factor K is calculated using the following formula: K=k1*a+k2*(1-a), where a is an adjustment coefficient used to adjust the ratio of the leading vehicle height and the leading vehicle width to the influence factor. The specific numerical ratio can be calibrated based on experiments; if the leading vehicle height has a greater impact, a can be set within the range of (0.5, 1.0).

[0030] This step first responds to the activation of the air conditioning internal and external circulation control function, and then determines the preceding vehicle impact factor. If the air conditioning internal and external circulation control function is not activated, there is no need to determine the preceding vehicle impact factor. The air conditioning internal and external circulation control function can be activated manually by the user or automatically.

[0031] In an optional embodiment, the method also includes: when the air conditioning internal and external circulation state is a partial external circulation state or a full external circulation state, and the ambient temperature of the vehicle is greater than a preset temperature or the light intensity is greater than a preset light intensity, determining that the air conditioning internal and external circulation control is started.

[0032] This embodiment is a way to automatically start the air conditioning internal and external circulation control function. When the air conditioning internal and external circulation state is a partial external circulation state or a full external circulation state, it means that outside air has entered the car, so there is a possibility that the outside air affects the air quality in the car, so it is necessary to further judge in combination with the external environment. This embodiment combines the vehicle's ambient temperature (i.e., the temperature of the vehicle's external environment) or light intensity (i.e., the light intensity of the vehicle's external environment) to judge. If the vehicle's ambient temperature is greater than the preset temperature, it means that the concentration of pollutants in the air is relatively high. If the light intensity is greater than the preset light intensity, it means that dust and other pollutants are easily generated in the air. When one of the above two conditions is met, the air conditioning internal and external circulation control function is automatically started. The above preset temperature can be 10~15℃, and the preset light intensity can be 100~150W / m 2 .

[0033] S120: Determine an adjustment angle of an air-conditioning damper according to the number of vehicles ahead and the distance between the vehicle ahead and the vehicle ahead.

[0034] Among them, the "number of vehicles in front" is the total number of vehicles in front of or in front of the vehicle, which can be collected by the front camera of the vehicle or monitored by the laser radar. The "distance between the vehicle and the vehicle in front" is the minimum distance between all vehicles in front and the vehicle in the X direction (i.e. the direction of travel of the vehicle). The "air conditioning damper adjustment angle" refers to the angle at which the damper used to control the amount of air entering from outside the vehicle in the air conditioner needs to be adjusted. Generally, the larger the angle at which the damper is opened, the greater the external circulation air volume. If the air quality outside the vehicle is poor, the damper opening angle needs to be reduced.

[0035] Since the more vehicles in front there are, the greater the impact of the vehicles in front on the air quality of the vehicles behind, and the greater the distance between the vehicle and the vehicle in front, the smaller the impact of the vehicles in front on the air quality of the vehicles behind, this step determines the air conditioning damper adjustment angle based on these two points.

[0036] In an optional implementation, determining the air conditioner damper adjustment angle according to the number of vehicles ahead and the distance between the vehicle ahead and the vehicle ahead includes: Obtaining a third mapping relationship between the number of vehicles ahead, the distance between the vehicle ahead and the vehicle ahead, and the adjustment angle of the air conditioner damper; The air conditioner damper adjustment angle is determined according to the third mapping relationship, the number of vehicles ahead, and the distance between the vehicle and the vehicle ahead.

[0037] The third mapping relationship can be obtained by calibration. At the same test site, different air conditioning circulation damper adjustment angles are set according to different front vehicle distances and the number of front vehicles. The PM2.5 concentration in the rear vehicle is tested during the driving process, and the data is recorded. For example, for the first time, there is one front vehicle and the front vehicle distance is 50m. The PM2.5 concentration in the rear vehicle is tested. If PM2.5 rises, the air conditioning circulation damper adjustment angle is increased until a suitable adjustment angle is found, and the data is recorded. In order to reduce the test conditions, the front vehicle distance can also be divided into equal intervals, such as 50m, 100m, and 150m, and then the calibration test is carried out. Finally, the third mapping relationship is established based on the recorded calibration test data.

[0038] Table 3 is an example of the third mapping relationship mentioned above.

[0039] Table 3 Number of vehicles ahead Distance between this vehicle and the vehicle ahead 50m 100m 150m 200m ... 1 5 4 3 2 ... 2 7 5 4 3 ... 3 9 7 5 4 ... 4 10 9 7 5 ... 5 11 10 9 7 ... ... ... ... ... ... ... S130: adjusting the opening angle of the air-conditioning damper according to the influence factor of the preceding vehicle, the adjustment angle of the air-conditioning damper and the initial angle of the air-conditioning damper.

[0040] The number of front vehicle impact factors changes with the number of front vehicles. For example, if there is one front vehicle, the number of front vehicle impact factors is 1. If there are multiple front vehicles, the number of front vehicle impact factors is multiple. In this case, it is necessary to take the average of multiple front vehicle impact factors and then apply them to the calculation of the air conditioning damper opening angle. "Air conditioning damper initial angle" refers to the initial opening angle of the air conditioning damper after the air conditioning internal and external circulation control function is started. This angle can be the angle set by the driver or the angle when the air conditioning internal and external circulation control function was turned off the last time.

[0041] Optionally, the air conditioning damper opening angle D can be calculated using the following formula: D=D0-D1*K, where D0 is the initial angle of the air conditioning damper, D1 is the adjustment angle of the air conditioning damper, and K is the influence factor of the preceding vehicle (if there are multiple preceding vehicles, the average value is taken here).

[0042] In an optional implementation, after adjusting the air conditioning damper opening angle according to the preceding vehicle impact factor, the air conditioning damper adjustment angle and the air conditioning damper initial angle, the method further includes: Determine the correction factor of the current detection cycle according to the in-vehicle air quality index of the current detection cycle, the in-vehicle air quality index before adjustment and the correction factor of the previous detection cycle; the correction factor is used to correct the air conditioner damper adjustment angle; According to the preceding vehicle impact factor, the air conditioning damper adjustment angle, the air conditioning damper initial angle and the correction factor of the current detection cycle, the air conditioning damper opening angle is adjusted again.

[0043] After adjusting the air conditioning damper opening angle once, the air quality in the vehicle will be improved, but whether the optimal index is reached is uncertain. Therefore, after adjusting the air conditioning damper opening angle for the first time, the present embodiment combines the air quality index in the vehicle in the current detection period, the air quality index in the vehicle in the previous detection period, and the correction factor of the previous detection period to determine the correction factor of the current detection period, and then adjusts the air conditioning damper opening angle again according to the influence factor of the previous vehicle, the air conditioning damper adjustment angle, the initial angle of the air conditioning damper, and the correction factor of the current detection period to meet the requirements of the optimal index. Among them, there are multiple "detection cycles", and each detection cycle detects the air quality index in the vehicle, that is, the air quality index in the vehicle should be detected at intervals and continuously, and the detection cycle is, for example, 10~20s. "Current detection cycle" is the detection cycle to which the correction factor belongs this time, including the first detection cycle (i.e., the first detection cycle after adjusting the air conditioning damper opening angle for the first time, such as detection at the 10th second), the second detection cycle (i.e., the second detection cycle after adjusting the air conditioning damper opening angle for the first time, such as detection at the 20th second), etc. Air quality indicators include, for example, the control quality index, PM2.5 concentration, or PM10 concentration. If the in-car air quality index of a certain detection cycle is significantly deteriorated compared to the in-car air quality index before adjustment, it means that the previous adjustment is not in place or is lagging behind, and it is necessary to further increase the adjustment angle. If the in-car air quality index of a certain detection cycle is not significantly deteriorated compared to the in-car air quality index before adjustment, it means that the previous adjustment is appropriate. If there is no obvious deterioration before a certain detection cycle, the correction factor of the current detection cycle is 1 (that is, the first adjustment of the air conditioning damper opening angle). If there is obvious deterioration before a certain detection cycle, the air conditioning damper opening angle has been adjusted again before, and the correction factor of the current detection cycle is the correction factor of the previous detection cycle.

[0044] Optionally, when adjusting again, the air-conditioning damper opening angle D2 can be calculated using the following formula: D2=D0-D1*K*X, where D0 is the initial angle of the air-conditioning damper, D1 is the adjustment angle of the air-conditioning damper, K is the influence factor of the preceding vehicle, and X is the correction factor.

[0045] In an optional implementation, a correction factor for the current detection cycle is determined based on the in-vehicle air quality index of the current detection cycle, the in-vehicle air quality index before adjustment, and the correction factor of the previous detection cycle; the correction factor is used to correct the air conditioner damper adjustment angle, including: When the current detection cycle is the first detection cycle and the difference between the in-vehicle air quality index in the current detection cycle and the in-vehicle air quality index before adjustment is less than a preset threshold, determining the correction factor of the current detection cycle to be 1; When the current detection cycle is the first detection cycle and the difference between the in-vehicle air quality index in the current detection cycle and the in-vehicle air quality index before adjustment is greater than or equal to a preset threshold, determining that the correction factor of the current detection cycle is greater than 1; When the current detection cycle is not the first detection cycle and the difference between the in-vehicle air quality index in the current detection cycle and the in-vehicle air quality index before adjustment is less than a preset threshold, determining that the correction factor of the current detection cycle is equal to the correction factor of the previous detection cycle; When the current detection cycle is not the first detection cycle and the difference between the in-vehicle air quality index of the current detection cycle and the in-vehicle air quality index before adjustment is greater than or equal to a preset threshold, it is determined that the correction factor of the current detection cycle is greater than the correction factor of the previous detection cycle.

[0046] This implementation method reflects whether the air quality has deteriorated significantly by the difference between the current detection cycle's in-vehicle air quality index and the in-vehicle air quality index before adjustment and the preset threshold, and combines whether the current detection cycle is the first detection cycle to determine the value of the correction factor of the current detection cycle. If the current detection cycle is not the first detection cycle, and the difference between the current detection cycle's in-vehicle air quality index and the in-vehicle air quality index before adjustment is less than the preset threshold, it means that the adjustment of the previous detection cycle is reasonable, so the correction factor of the previous detection cycle is used; if the current detection cycle is not the first detection cycle, and the difference between the current detection cycle's in-vehicle air quality index and the in-vehicle air quality index before adjustment is greater than or equal to the preset threshold, it means that the adjustment of the previous detection cycle is insufficient or lagging, so it is necessary to further increase the correction factor in the correction factor of the previous detection cycle to improve the air quality in the car, such as the correction factor of the previous detection cycle is 2, and the correction factor of the current detection cycle can be 2.5 or 3, etc.

[0047] In the above implementation, the specific value of the correction factor of the current detection cycle is actually adjusted by self-learning and self-adaptation. In another optional implementation, after adjusting the air-conditioning damper opening angle according to the preceding vehicle impact factor, the air-conditioning damper adjustment angle and the air-conditioning damper initial angle, it also includes: Obtaining a fourth mapping relationship between the in-vehicle air quality index at a preset detection time, the in-vehicle air quality index before adjustment, and the correction factor; Determine a correction factor according to the fourth mapping relationship, the in-vehicle air quality index at the preset detection time, and the in-vehicle air quality index before adjustment; the correction factor is used to correct the air conditioner damper adjustment angle; According to the impact factor of the vehicle in front, the adjustment angle of the air-conditioning damper, the initial angle of the air-conditioning damper and the correction factor, adjust the opening angle of the air-conditioning damper again.

[0048] This embodiment is different from the previous embodiment. It only uses the in-vehicle air quality index at the preset detection time (for example, 1min, 2min, 5min, etc.), and does not need to use the in-vehicle air quality index of multiple detection cycles. It also obtains the fourth mapping relationship between the in-vehicle air quality index at the preset detection time, the in-vehicle air quality index before adjustment, and the correction factor. The fourth mapping relationship can be obtained in advance through experimental calibration. For example, the difference between the in-vehicle air quality index at the preset detection time and the in-vehicle air quality index before adjustment can be divided into different intervals in order of size, and each interval is corrected by a different correction factor. The correction factor can ensure that the in-vehicle air quality after correction can meet the standard. Therefore, this embodiment only needs to adjust the air conditioner damper opening angle once and again to meet the requirements, and there is no need to make multiple adjustments.

[0049] The above-mentioned air-conditioning internal and external circulation control method determines the front vehicle influence factor based on the front vehicle height and the front vehicle width, determines the air-conditioning damper adjustment angle based on the number of front vehicles, the distance between the vehicle and the front vehicle and the speed of the front vehicle, and finally adjusts the air-conditioning damper opening angle according to the front vehicle influence factor and the air-conditioning damper adjustment angle obtained above, combined with the air-conditioning damper initial angle, thereby taking into account all aspects of the front vehicle on the rear air. Therefore, the adjustment of the air-conditioning damper opening angle is more accurate and reliable. In addition, this method automatically adjusts the air-conditioning damper opening angle in response to the start-up of the air-conditioning internal and external circulation control function, without the need for manual adjustment by the user, and intelligently controls the internal and external circulation of the air-conditioning system to ensure a clean and healthy air environment in the vehicle.

At least one processor in the electronic device can perform the above method, and thus has at least the same advantages as the above method.

[0053] Optionally, the electronic device also includes interfaces for connecting various components, including high-speed interfaces and low-speed interfaces. The various components are connected to each other using different buses and can be installed on a common mainboard or installed in other ways as needed. The processor can process instructions executed in the electronic device, including instructions stored in or on a memory to display graphical information of a GUI (Graphical User Interface) on an external input / output device (such as a display device coupled to an interface). In other embodiments, if necessary, multiple processors can be used together with multiple memories, and / or multiple buses can be used together with multiple memories. Similarly, multiple electronic devices can be connected (for example, as a server array, a group of blade servers, or a multi-processor system), and each device provides some necessary operations.
