[0024] Figure 3 is a functional block diagram of a vehicle according to an exemplary embodiment. DETAILED DESCRIPTION

[0025] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, like reference numerals refer to like elements throughout the description. The following exemplary embodiments are not representative of all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0026] Figure 1 is a flow chart of a vehicle air conditioner fan control method according to an exemplary embodiment, as shown in Figure 1 The method is applied to a controller of a vehicle air conditioner system, and includes the following steps.

[0027] In step S11, the passenger cabin load of the vehicle is determined.

[0028] In the embodiments of the present disclosure, the passenger cabin load of the vehicle can be calculated according to the current ambient temperature, the current humidity in the passenger cabin, the current solar radiation, the current vehicle speed, and the number of passengers in the passenger cabin.

[0029] In step S12, the target air volume sub-interval is determined from the plurality of air volume sub-intervals according to the passenger cabin load.

[0030] The air volume of the vehicle air conditioner fan is divided into a plurality of air volume intervals, each air volume interval is divided into a plurality of air volume sub-intervals, the air volume difference between adjacent air volume sub-intervals in the same air volume interval is the same, the air volume difference between adjacent air volume sub-intervals in different air volume intervals is different.

[0031] In the embodiments of the present disclosure, the greater the air volume of the air volume interval, the greater the air volume difference between the maximum air volume and the minimum air volume corresponding to the air volume interval, the smaller the air volume of the air volume interval, and the smaller the air volume difference between the maximum air volume and the minimum air volume corresponding to the air volume interval. For example, in the case where the air volume of the vehicle air conditioner fan is divided into three air volume intervals, the maximum air volume that the first air volume interval can provide is less than the minimum air volume that the second air volume interval can provide, the maximum air volume that the second air volume interval can provide is less than the minimum air volume that the third air volume interval can provide, the air volume difference between the maximum air volume and the minimum air volume that the first air volume interval can provide is a first air volume difference, the air volume difference between the maximum air volume and the minimum air volume that the second air volume interval can provide is a second air volume difference, the air volume difference between the maximum air volume and the minimum air volume that the third air volume interval can provide is a third air volume difference, the first air volume difference is less than the second air volume difference, and the second air volume difference is less than the third air volume difference. Moreover, the number of air volume sub-intervals in the first air volume interval is greater than the number of air volume sub-intervals in the second air volume interval, and the number of air volume sub-intervals in the second air volume interval is greater than the number of air volume sub-intervals in the third air volume interval.

[0032] In the embodiments of the present disclosure, for adjacent air volume intervals, the air volume difference between adjacent air volume sub-intervals in the air volume interval with low air volume is less than the air volume difference between adjacent air volume sub-intervals in the air volume interval with high air volume.

[0033] In the embodiments of the present disclosure, the air volume provided by all air volume sub-intervals in the plurality of air volume sub-intervals does not overlap, and similarly, the air volume provided by all air volume intervals also does not overlap, that is, the air volume provided by all air volume sub-intervals is unique, and the air volume provided by all air volume intervals is also unique.

[0034] Using the above embodiments for illustration, the air volume difference between adjacent air volume sub-intervals in the first air volume interval is less than the air volume difference between adjacent air volume sub-intervals in the second air volume interval, and similarly, the air volume difference between adjacent air volume sub-intervals in the second air volume interval is less than the air volume difference between adjacent air volume sub-intervals in the third air volume interval. For example, the air volume difference between adjacent air volume sub-intervals in the first air volume interval is 20 cubic meters / hour, which is less than the air volume difference between adjacent air volume sub-intervals in the second air volume interval, which is 50 cubic meters / hour, and similarly, the air volume difference between adjacent air volume sub-intervals in the second air volume interval is 50 cubic meters / hour, which is less than the air volume difference between adjacent air volume sub-intervals in the third air volume interval, which is 100 cubic meters / hour.

[0035] In the embodiments of the present disclosure, the air volume other than the minimum air volume and the maximum air volume can be divided into air volume intervals and air volume sub-intervals, that is, the maximum air volume and the minimum air volume are not included in the air volume intervals.

[0036] In step S13, the gear of the vehicle air conditioner fan is adjusted to the gear corresponding to the target air volume sub-interval.

[0037] There is a one-to-one correspondence between the speed setting of the vehicle air conditioner fan and the air volume range.

[0038] In this embodiment of the disclosure, a mapping table can be established between each wind quantum interval and the speed of the vehicle air conditioner fan. In the mapping table, a wind quantum interval mapped to each speed and an air volume mapped to each wind quantum interval can be queried.

[0039] Optionally, in step S12, determining the target wind quantum interval from a preset plurality of wind quantum intervals based on the occupant cabin load includes:

[0040] In response to the activation of the vehicle's air conditioning fan, the first airflow frequency range is determined based on the passenger compartment load, the current ambient temperature, and the preset air outlet temperature.

[0041] The action of turning on the vehicle air conditioning fan mentioned here refers to the start-up action under the automatic control model of the vehicle air conditioning fan. When the vehicle air conditioning fan is in manual control mode, the control logic of the vehicle air conditioning fan control method disclosed herein is disregarded, and the air volume of the vehicle air conditioning fan is adjusted according to the user-set level.

[0042] The preset air outlet temperature is the panel temperature set by the user in the semi-automatic control mode of the air conditioner. In the fully automatic control mode, the preset air outlet temperature can be 22-30 degrees Celsius, which may vary depending on the season.

[0043] In this embodiment of the disclosure, the first wind quantum interval can be determined by the following formula:

[0044] Q cabin =(T out –T set )×FRG(N) (1)

[0045] Among them, Q cabin This refers to the load on the crew cabin, expressed as heat, measured in kW (tons). out It is the current ambient temperature, T set It is the preset air outlet temperature, and FRG(N) is the first air quantum range.

[0046] The wind quantum interval with the largest wind volume among multiple wind quantum intervals, where the wind volume is greater than that of the first wind quantum interval and the wind volume difference between the two is the smallest, is selected as the target wind quantum interval.

[0047] For example, the first air volume interval is divided into 4 air volume sub-intervals, the second air volume interval is divided into 3 air volume sub-intervals, and the third air volume interval is divided into 2 air volume sub-intervals. If the first air volume sub-interval is the third air volume sub-interval in the first air volume interval, the target air volume sub-interval is determined as the fourth air volume sub-interval in the first air volume interval, wherein the fourth air volume sub-interval can provide an air volume greater than that of the third air volume sub-interval, and the fourth air volume sub-interval is adjacent to the third air volume sub-interval.

[0048] In this way, in the initial stage of the operation of the vehicle air conditioner, the passenger compartment can be quickly heated or cooled by a large air volume.

[0049] Optionally, the method comprises:

[0050] In the case where the gear of the vehicle air conditioner fan is adjusted to the gear corresponding to the target air volume sub-interval, the first preset time length is run.

[0051] After running the first preset time length, the following steps are cyclically executed in the running process of the vehicle air conditioner fan:

[0052] The second preset time length is interval, and the steady-state load is determined according to the current ambient temperature, the preset outlet air temperature, and the air volume corresponding to the target air volume sub-interval.

[0053] The steady-state load can also be calculated by the above formula, except that the unknown quantity is the steady-state load, and the known quantities are the current ambient temperature, the preset outlet air temperature, and the current air volume sub-interval.

[0054] In one implementation, the second preset time length can be shorter than the first preset time length. In this way, in the initial stage of the operation of the air conditioner, a relatively large air volume and a relatively long time are provided to quickly heat or cool, and in the middle stage of the operation of the air conditioner, a relatively small air volume and a relatively short time are provided to continuously calculate and adjust the air volume, thereby improving the comfort of the vehicle air conditioning system.

[0055] According to the size relationship between the passenger compartment load and the steady-state load, it is determined whether the target air volume sub-interval meets the passenger compartment load.

[0056] The size relationship between the passenger compartment load and the steady-state load can be obtained by subtracting the steady-state load from the passenger compartment load. In the case where the passenger compartment load is greater than the steady-state load or the passenger compartment load is less than the steady-state load, it is determined that the target air volume sub-interval does not meet the passenger compartment load.

[0057] In one of the manners, the target air volume subinterval is determined not to satisfy the passenger cabin load in a case where a difference between the passenger cabin load and the steady-state load exceeds a preset difference threshold. In particular, in a case where the target air volume subinterval is in an air volume interval capable of providing a large air volume.

[0058] The preset difference threshold is positively correlated with a difference in air volume between adjacent air volume subintervals in the air volume interval, that is, the smaller the difference in air volume between adjacent air volume subintervals in the air volume interval, the smaller the preset difference threshold corresponding to the air volume interval; the larger the difference in air volume between adjacent air volume subintervals in the air volume interval, the larger the preset difference threshold corresponding to the air volume interval.

[0059] In a case where the target air volume subinterval does not satisfy the passenger cabin load, a neighboring air volume subinterval of the target air volume subinterval is taken as a new target air volume subinterval according to a positive-negative relationship between the passenger cabin load and the steady-state load.

[0060] In an embodiment, in a case where the passenger cabin load is greater than the steady-state load, an air volume subinterval neighboring the target air volume subinterval and capable of providing an air volume smaller than that of the target air volume subinterval is taken as a new target air volume subinterval; in a case where the passenger cabin load is smaller than the steady-state load, an air volume subinterval neighboring the target air volume subinterval and capable of providing an air volume greater than that of the target air volume subinterval is taken as a new target air volume subinterval.

[0061] In the present disclosure, the optimal air volume of the vehicle-mounted air fan can be queried based on an optimal air volume algorithm, and then the steady-state load of the passenger cabin is calculated according to environmental factors and the like, and the next optimal air fan air volume is entered through a neighboring gear jump, so as to quickly perform air volume jump. When the environment changes and the like are restored, the passenger cabin load is also restored, and the target air volume subinterval before the jump can also be jumped to again, which is applicable to both the average distribution air fan air volume and the gradient distribution air fan air volume.

[0062] Optionally, the air volume of the vehicle-mounted air conditioner fan is divided into a low air volume interval and a high air volume interval.

[0063] The air volume of each air volume subinterval in the low air volume interval is divided in the following manner: a first air volume difference of the low air volume interval is determined according to a minimum air volume of the vehicle-mounted air conditioner fan, a preset passenger cabin load, and a number of preset air volume gears of the vehicle-mounted air conditioner fan; and the air volume of each air volume subinterval in the low air volume interval is determined by taking the minimum air volume as a starting air volume of the low air volume interval and the first air volume difference as an air volume step.

[0064] In an embodiment of the present disclosure, the air volume FRG(n) of each air volume subinterval in the low air volume interval can be calculated by the following formula:

[0065] FRG(n) = MNSFR + [(LFP - MNSFR) / (FRG - 2)] / 2*n (2)

[0066] wherein MNSFR is the minimum air volume that the vehicle-mounted air fan can provide, LFP is a preset passenger compartment load, the preset passenger compartment load is related to a season, and FRG is the number of preset air volume gears of the vehicle-mounted air conditioner fan. It can be understood that the first air volume difference of the low air volume interval can be calculated in the formula (2) [(LFP - MNSFR) / (FRG - 2)] / 2. n is the gear of the air volume sub-interval in the low air volume interval. For example, the air volume sub-interval corresponding to the minimum air volume is FRG(0), the next minimum air volume sub-interval is FRG(1) = MNSFR + [(LFP - MNSFR) / (FRG - 2)] / 2*1, and the third minimum air volume sub-interval is FRG(1) = MNSFR + [(LFP - MNSFR) / (FRG - 2)] / 2*2.

[0067] The air volume of the plurality of air volume sub-intervals in the high air volume interval is divided in the following manner: according to the maximum air volume of the vehicle-mounted air conditioner fan, the preset passenger compartment load, the number of preset air volume gears of the vehicle-mounted air conditioner fan, and the number of preset air volume sub-intervals in the low air volume interval, a second air volume difference of the high air volume interval is determined; and the maximum air volume of the low air volume interval is taken as the starting point of the calculation of the high air volume interval, and the second air volume difference is taken as the air volume step, so as to determine the air volume of each air volume sub-interval in the high air volume interval.

[0068] wherein the maximum air volume of the low air volume interval belongs to the low air volume interval, and the high air volume interval is determined according to the maximum air volume of the low air volume interval and the second air volume difference, so as to determine the minimum air volume that the high air volume interval can provide.

[0069] In the embodiments of the present disclosure, the air volume FFR(m) of each air volume sub-interval in the high air volume interval can be calculated by the following formula:

[0070] FFR(m) = (MASFR - LFP) / [n - (FRG - 2) / 2]*m + LFP (3)

[0071] wherein MASFR is the maximum air volume of the vehicle-mounted air conditioner fan, LFP is the preset passenger compartment load, FRG is the number of preset air volume gears of the vehicle-mounted air conditioner fan, and n is the number of preset air volume sub-intervals in the low air volume interval. It can be understood that the second air volume difference of the high air volume interval can be calculated in the formula (3) (MASFR - LFP) / [n - (FRG - 2) / 2]. m is the gear of the air volume sub-interval in the high air volume interval.

[0072] Optionally, the method comprises:

[0073] acquire door and window switch change information of the vehicle, the door and window switch change information comprising at least one of door opening number change information, same side door opening change information and window opening amplitude change information;

[0074] The door opening number change information comprises door opening number increase and door opening number decrease; the same side door opening change information comprises one or two same side doors being opened, and one or more different side doors being opened; and the window opening amplitude change information comprises window opening amplitude increase or window opening amplitude decrease.

[0075] According to the door and window change condition represented in the door and window switch change information, it is determined whether there is a target air volume interval in the air volume interval, the target air volume interval being an air volume interval in which the air volume change trend meets the door and window change condition compared with the air volume of the target air volume sub-interval, and the door and window change condition comprising door and window opening degree value increase or door and window opening degree value decrease.

[0076] In the embodiment of the present disclosure, the air volume change trend meeting the door and window change condition means that the door and window opening degree value represented in the door and window change information decreases, and the air volume of the target air volume interval decreases compared with the air volume of the air volume interval in which the target air volume sub-interval is located; and the door and window opening degree value represented in the door and window change information increases, and the air volume of the target air volume interval increases compared with the air volume of the air volume interval in which the target air volume sub-interval is located.

[0077] In the case where the target air volume interval exists, a first demand air volume sub-interval is determined from the air volume sub-intervals of the target air volume interval according to the change amount represented in the door and window switch change information.

[0078] In the embodiment of the present disclosure, the greater the change amount represented in the door and window switch change information, the greater the air volume difference between the air volume that can be provided by the first demand air volume sub-interval and the air volume that can be provided by the target air volume sub-interval.

[0079] The first demand air volume sub-interval is replaced by the target air volume sub-interval.

[0080] Optionally, the method comprises:

[0081] In the case where the target air volume interval does not exist, it is determined whether there is a candidate air volume sub-interval in the air volume interval in which the target air volume sub-interval is located according to the door and window change trend represented in the door and window switch change information, the candidate air volume sub-interval being an air volume sub-interval in which the air volume change trend meets the door and window change condition compared with the air volume of the target air volume sub-interval.

[0082] Similarly, the wind volume change trend satisfying the wind volume sub-interval of the door and window change information is that, if the door and window change information represents that the door and window opening degree value decreases, the wind volume of the alternative wind volume sub-interval is smaller than the wind volume of the wind volume interval in which the target wind volume sub-interval is located; or if the door and window change information represents that the door and window opening degree value increases, the wind volume of the alternative wind volume sub-interval is larger than the wind volume of the wind volume interval in which the target wind volume sub-interval is located.

[0083] In the case that the alternative wind volume sub-interval exists, the second required wind volume sub-interval is determined from the alternative wind volume sub-interval according to the change amount represented in the door and window switch change information.

[0084] Similarly, the larger the change amount represented in the door and window switch change information, the larger the wind volume difference between the wind volume that can be provided by the second required wind volume sub-interval and the wind volume that can be provided by the target wind volume sub-interval.

[0085] The second required wind volume sub-interval is replaced by the target wind volume sub-interval.

[0086] Optionally, the determining whether the target wind volume interval exists in the wind volume interval according to the door and window change represented in the door and window switch change information comprises:

[0087] In the case that the door and window change represented in the door and window switch change information is that the door and window opening degree value decreases, it is determined whether the first alternative wind volume interval exists in the wind volume interval, and the maximum wind volume of the first alternative wind volume interval is smaller than the minimum wind volume of the wind volume interval in which the target wind volume sub-interval is located.

[0088] In the case that the first alternative wind volume interval exists, it is determined whether the target wind volume interval exists in the first alternative wind volume interval according to the decrease amount of the door and window opening degree value.

[0089] Optionally, the determining whether the target wind volume interval exists in the wind volume interval according to the door and window change represented in the door and window switch change information comprises:

[0090] In the case that the door and window change represented in the door and window switch change information is that the door and window opening degree value increases, it is determined whether the second alternative wind volume interval exists in the wind volume interval, and the minimum wind volume of the second alternative wind volume interval is larger than the maximum wind volume of the wind volume interval in which the target wind volume sub-interval is located.

[0091] In the case that the second alternative wind volume interval exists, it is determined whether the target wind volume interval exists in the second alternative wind volume interval according to the increase amount of the door and window opening degree value.

[0092] In the embodiments of the present disclosure, the opening amplitude of the vehicle window with the largest opening amplitude or the smallest opening amplitude in the vehicle window can be taken as the vehicle window opening amplitude change information according to the wind volume interval in which the target wind volume sub-interval is located, or the vehicle window opening amplitude change information can be calculated by weighting the multiple vehicle window opening amplitudes.

[0093] Take the high and low wind volume intervals as examples, where the low wind volume interval does not include the minimum wind volume, and the high wind volume interval does not include the maximum wind volume. The low wind volume interval includes 5 wind volume sub-intervals, and the high wind volume interval includes 2 wind volume sub-intervals. When the vehicle windows are opened, if a single window on one side is opened, if the target wind volume sub-interval is in the low wind volume interval, when the window opening amplitude is less than half of the entire window opening amplitude, the wind volume sub-interval with the maximum wind volume in the low wind volume interval is taken as the new target wind volume sub-interval; when the window opening amplitude is greater than half of the entire window opening amplitude, the wind volume sub-interval with the minimum wind volume in the high wind volume interval is taken as the new target wind volume sub-interval. If the target wind volume sub-interval is in the high wind volume interval, when the window opening amplitude is less than half of the entire window opening amplitude, the wind volume sub-interval with the maximum wind volume in the high wind volume interval is taken as the new target wind volume sub-interval; when the window opening amplitude is greater than half of the entire window opening amplitude, the maximum wind volume of the vehicle air conditioner fan is directly taken as the target wind volume.

[0094] When the vehicle windows are opened, if two windows on one side are opened, the window opening amplitude with the maximum window opening amplitude is taken as the calculation standard, and the operation mode is the same as that of the single window on one side.

[0095] When the vehicle windows are closed, if a single window on one side is opened, if the target wind volume sub-interval is in the low wind volume interval, when the window closing amplitude is less than half of the entire window opening amplitude, the wind volume sub-interval with the minimum wind volume in the low wind volume interval is taken as the new target wind volume sub-interval; when the window closing amplitude is greater than half of the entire window opening amplitude, the minimum wind volume is taken as the target wind volume. If the target wind volume sub-interval is in the high wind volume interval, when the window closing amplitude is less than half of the entire window opening amplitude, the wind volume sub-interval with the maximum wind volume in the low wind volume interval is taken as the new target wind volume sub-interval; when the window closing amplitude is greater than half of the entire window opening amplitude, the wind volume sub-interval with the second minimum wind volume in the low wind volume interval is taken as the new target wind volume sub-interval.

[0096] When the vehicle windows are closed, if two windows on one side are closed, or three windows on one side are closed, or four windows on one side are closed, the window closing amplitude with the minimum window closing amplitude is taken as the calculation standard, and the operation mode is the same as that of the single window on one side.

[0097] In the case of opening the door, if a single door is opened, if the target air volume sub-interval is in the low air volume interval, the air volume sub-interval with the largest air volume in the low air volume interval is taken as the new target air volume sub-interval; if the target air volume sub-interval is in the high air volume interval, the air volume sub-interval with the largest air volume in the high air volume interval is taken as the new target air volume sub-interval. If a single door is opened, or double doors are opened on one side, or double doors are opened on both sides, or three doors are opened on both sides, or four doors are opened on both sides, the maximum air volume of the air fan of the vehicle-mounted air conditioner is directly taken as the target air volume. For vehicles with a trunk door connected to the vehicle interior, such as SUVs. If the trunk door is opened, if the target air volume sub-interval is in the low air volume interval, the air volume sub-interval performs a +1 operation, that is, the air volume increases by one air volume sub-interval. If the target air volume sub-interval is in the high air volume interval, the maximum air volume of the air fan of the vehicle-mounted air conditioner is directly taken as the target air volume. After the trunk door is closed, the air volume sub-interval performs a -1 operation.

[0098] Based on the same concept, the present disclosure also provides a vehicle-mounted air conditioner air fan control device for executing part or all of the steps of the vehicle-mounted air conditioner air fan control method provided by the above-mentioned method embodiment. The device 200 can realize the vehicle-mounted air conditioner air fan control method in the form of software, hardware or a combination of both. Figure 2 is a block diagram of a vehicle-mounted air conditioner air fan control device according to an exemplary embodiment, referring to Figure 2 As shown in the figure, the device 200 includes a first determination module 210, a second determination module 220 and an adjustment module 230.

Optionally, each of the identified objects can be dependent on the behavior of the others, and thus all of the identified objects can be considered together to predict the behavior of a single identified object. The vehicle 400 can adjust its speed based on the predicted behavior of the identified objects. In other words, the autonomous vehicle can determine what steady state the vehicle will need to adjust to (e.g., speed up, slow down, or stop) based on the predicted behavior of the objects.
