In an exemplary embodiment, such an odor adjustment system 1000 may further comprise: a window 9, a skylight 10, an air intake motor 11, an inside-outside circulation converter 12 and/or a fragrance box 5. Optionally, such an odour regulation system 1000 may also comprise an off-board temperature sensor 15 and/or a rain sensor 16 and/or a vehicle speed sensor 17.

Fig. 2 shows a schematic block diagram of a control module included in a process controller 900 according to an exemplary embodiment of the present invention.

As shown in fig. 2, the process controller 900 may include: a background server module 913, an in-vehicle entertainment terminal module 914, an aroma control module 904, a window control module 906, a sunroof control module 907, and/or an air conditioner control module 908.

In an exemplary embodiment, for example, it can be achieved that the off-board odor sensor 2 detects odors and transmits odor signals to the fragrance control module 904; the in-vehicle entertainment terminal module 914 is configured to implement the relevant functional settings of the scent conditioning system 1000; the background server module 913 is configured and adapted to provide a regulation smell operation command employed on the area or planned route where the vehicle is located to the process controller 900 based on the user operation big data, so that the process controller 900 controls the relevant modules; the window control module 906 is configured and adapted to control the lifting of the window 9; the sunroof control module 907 is configured to control opening and closing of the sunroof 10.

Fig. 3 shows an odor sensor arrangement according to an exemplary embodiment of the present invention.

In the example shown in fig. 3, a first outside air smell sensor 21 and a second outside air smell sensor 22 are exemplarily provided. The first outside air taste sensor 21 and the second outside air taste sensor 22 may be disposed at any position outside the vehicle body, and may be disposed at the vehicle head and/or the vehicle tail, for example.

In the example shown in fig. 3, a first in-vehicle smell sensor 31 and a second in-vehicle smell sensor 32 are exemplarily provided. Optionally, a third in-vehicle smell sensor 33 and a fourth in-vehicle smell sensor 34 may be further provided. These in-vehicle odor sensors may be disposed at any position in the vehicle, for example, may be disposed on the side walls and/or the ceiling of the interior of the vehicle compartment. For example, the first in-vehicle smell sensor 31, the second in-vehicle smell sensor 32, the third in-vehicle smell sensor 33, and the fourth in-vehicle smell sensor 34 may be arranged corresponding to the first window 91, the second window 92, the third window 93, and the fourth window 94, respectively (see fig. 3).

In an exemplary embodiment, one or more seat sensors 14 are included (see FIG. 1). The seat sensor 14 may be a camera or a pressure sensor. The seat sensor 14 is configured and adapted to detect: whether a person is located at the seat corresponding to the seat sensor 14. The process controller 900 combines the vehicle occupant seating distribution information provided by the seat sensor 14 with the outside smell information and/or the inside smell information to control the opening and closing of the windows, thereby ensuring the inside air quality.

According to an example, in connection with the arrangement of in-vehicle outside smell sensors exemplarily shown in fig. 3 and in connection with the seat sensor 14, the control strategy for the window 9 may be: a) when only one detection value of the vehicle

interior smell sensors

31, 32, 33 and 34 is larger than or equal to a preset threshold value, the corresponding side vehicle window corresponding to the sensor is controlled to be opened, and the smell is quickly and pertinently adjusted by utilizing the negative pressure principle; b) diagonal windows, for example, when any two detection values of the vehicle

interior odor sensors

31, 32, 33 and 34 are larger than or equal to a preset threshold value, the seat sensor 14 is combined to detect the seating condition of the passenger, and front and rear diagonal windows on which no member sits are controlled to be opened; c) only closing the front window on one side, opening the other three windows, for example, closing the windows on the sitting side and opening the other three windows for quick ventilation by combining the detection condition of the seat sensor 14 when any three detection values of the

air smell sensors

31, 32, 33 and 34 in the vehicle are more than or equal to the preset threshold value.

Here, for the above strategy a), for example, in combination with fig. 3, if only the detection value of the fourth interior odor sensor 34 is greater than or equal to the preset threshold value, the fourth window 94 corresponding to the fourth interior odor sensor 34 is opened.

Here, with respect to the above-described strategy b), for example, in conjunction with fig. 3, if the detected values of any two of the in-

vehicle smell sensors

31, 32, 33, 34 are equal to or greater than the preset threshold value and the seat sensor 14 detects that a passenger (driver) is seated at the first window 91, the second window 92 and the third window 93 are opened, thereby causing convection to remove the smell.

Here, with respect to the above-described strategy c), for example, in conjunction with fig. 3, if the detection values of any three of the in-

vehicle smell sensors

31, 32, 33, 34 are equal to or greater than the preset threshold value and the seat sensor 14 detects that a passenger (driver) is seated in the first window 91, the first window 91 is closed, and the second window 92, the third window 93 and the fourth window 94 are opened, and rapid ventilation is performed.

Here, it can be understood that the ventilation efficiency is highest when three windows are opened.

The respective outside-vehicle odor sensor 2 and/or inside-vehicle odor sensor 3 and/or seat sensor 14 may be arranged at different positions inside and outside the vehicle, respectively, to establish a fully covered measurement field. The data of the sensors can in this case be used independently and/or in conjunction with one another to determine whether to carry out the method steps described in more detail below.

The specific functional manner of the components and/or modules illustrated in fig. 1-3 will be described further below in connection with the flow steps of an exemplary method according to the present invention.

Fig. 4 shows a flow chart of an odor adjustment method for a vehicle passenger compartment according to an exemplary embodiment of the present invention.

As shown in fig. 4, in step S100, the in-vehicle air quality is detected, and the in-vehicle air quality information is acquired. In this case, the detection is carried out in particular by means of the vehicle interior odor sensor 3.

According to an example, step S100 may also grade the detected in-vehicle air quality such that the in-vehicle air quality information includes a result of grading the in-vehicle smell, which may be one of the intensities in table 1 below.

TABLE 1 malodour intensity grading method

Strength of	Index (I)
		0	Is tasteless
1	The smell is barely felt
		2	The smell is weak but the properties can be distinguished
3	Easily feel the smell
		4	Strong odor
5	Intolerable strong odor

Next, in step S200, the outside air quality is detected, and outside air quality information is acquired. Here, the detection is performed in particular by means of an offboard odor sensor 2.

According to an example, step S200 may rank the detected air quality outside the vehicle such that the air quality outside the vehicle information includes a result of ranking the odor outside the vehicle, which may also be one of the intensities in table 1.

Next, in step S300, a vehicle passenger compartment odor adjustment strategy is determined in consideration of vehicle occupant seating distribution information based on the in-vehicle air quality information and/or the out-vehicle air quality information.

According to an example, the step S300 may compare the air quality information inside and outside the vehicle with preset thresholds, respectively.

According to an example, the threshold is a preset fixed value, such as the intensity level 2 in table 1. In another example, the threshold is variable and may be related to at least one of a number of factors including ambient temperature outside the vehicle, ambient temperature inside the vehicle, season and solar radiation, and user habits of vehicle personnel that have previously been uploaded to the background database.

According to an example, when the odor level outside the vehicle (for example intensity level 1 in table 1) is less than a preset threshold (for example intensity level 2 in table 1) and the odor level inside the vehicle (for example intensity level 3 in table 1) is greater than a preset threshold (for example intensity level 2 in table 1), then the odor regulating strategy that may be adopted is to open the windows 9 and/or the sunroof 10, and optionally to turn on the air conditioner and switch the outside circulation mode at this time.

According to an example, when the odor level outside the vehicle (e.g., intensity level 3 in table 1) is greater than a preset threshold (e.g., intensity level 2 in table 1) and the odor level inside the vehicle (e.g., intensity level 1 in table 1) is less than a preset threshold (e.g., intensity level 2 in table 1), then the odor adjustment strategy that may be taken is to turn on the air conditioner and switch the internal circulation mode, and at this time the windows 9 and the skylights 10 should be closed.

Fig. 5 shows a flow chart of specific method steps for a method for odor regulation of a vehicle passenger compartment according to an exemplary embodiment of the present invention.

In the following, the odour-conditioning method for a vehicle passenger compartment according to the invention is exemplarily explained in connection with a flow chart of specific method steps of the odour-conditioning method for a vehicle passenger compartment according to one exemplary embodiment of the invention as shown in fig. 5. Here, first, in step S101', the in-vehicle entertainment terminal module 914 sets the odor regulation system-related function for the vehicle passenger compartment. Then, in step S102 ', it is checked whether the odour control system for the passenger compartment of the vehicle is switched on, wherein if not, it jumps back to step S101 ', whereas if it is switched on, it jumps to step S103 '. In step S103 ', it is checked whether the big data assist function of the background server module 913 is turned on, wherein if not, the process goes to step S106 ', otherwise, if turned on, the process goes to step S104 '. In step S104 ', it is checked whether the user operation rate of the background data in the current region is greater than or equal to a preset threshold, wherein if the user operation rate is greater than or equal to the preset threshold, the step S105 ' is skipped, otherwise, the step S106 ' is skipped if the user operation rate is less than the preset threshold. For example, in step S104 ', for example, when the vehicle passes through a specific road segment (such as a specific garbage station), more than 90% of the users displaying the big data stored in the background server module 913 adopt the operation of closing the window skylight, that is, the current region background data user operation rate (90%) is greater than the preset threshold (for example, the user is preset to 50%), then the process goes to step S105'. In step S105 ', most user operations (here, for example, closing a window skylight) are performed in advance and the process jumps to step S106'. In step S106', the odor inside and outside the vehicle is detected and the signal is classified, wherein the classification method may refer to the malodor intensity classification method shown in table 1 above, for example. Then, in step S107 ', the vehicle interior outside air odor level is compared with a preset threshold value, and if the vehicle interior outside air odor level is less than or equal to the preset threshold value, the process goes to step S111 ', otherwise, the process goes to step S108 '. In step S111 ', it is checked whether a correlation adjustment has already been performed, wherein if a correlation adjustment has already been performed, the process jumps to step S112 ', whereas if no correlation adjustment has been performed, the process jumps back to step S106 '. For example, in step S111 ', it is recognized that the relevant adjustment (here, for example, the above-described operation of closing the sunroof) has been performed, and the process proceeds to step S112'. In step S112 ', uploading of operation data to the background is resumed before the vehicle state before the window skylight closing operation is taken, for example, in step S106', and the process jumps back to step S106 ', where the vehicle state before the window skylight closing operation is taken, that is, the window skylight is opened, and then the process jumps back to step S106' to re-detect whether the relevant operation (here, the window skylight closing operation, for example) has not been taken. In step S108 ', it is checked whether the vehicle exterior odor level is greater than the threshold value and the vehicle interior odor level is equal to or less than the threshold value, wherein if the vehicle exterior odor level is greater than the threshold value and the vehicle interior odor level is equal to or less than the threshold value, the process proceeds to step S109 ', whereas if this is not the case, the process proceeds to step S113 '. In step S109 ', the air conditioner is turned on and the internal circulation mode is switched and a transition is made to step S110'. In step S110 ', the window skylight is closed and the process jumps to step S106'. In step S113 ', it is checked whether the vehicle exterior odor level is equal to or less than a threshold value and the vehicle interior odor level is greater than the threshold value, wherein if the vehicle exterior odor level is equal to or less than the threshold value and the vehicle interior odor level is greater than the threshold value, the process proceeds to step S114 ', whereas if this is not the case, the process proceeds to step S117 '. In step S114 ', the air conditioner is turned on and the external circulation mode is switched, and it jumps to step S116'. In step S116 ', the window skylight is opened and the process jumps to step S106'. In step S117 ', the air conditioner is turned on and the internal circulation mode is switched and a jump is made to step S118'. In step S118 ', the window skylight is closed and the process jumps to step S119'. In step S119 ', the fragrance box is switched to the air freshening type and jumps to step S106'. Alternatively, in step S114 ', it is also possible to jump to step S115'. In step S115 ', it is checked whether or not the vehicle outside temperature is equal to or higher than a temperature threshold value (or whether or not the vehicle speed is equal to or higher than a vehicle speed threshold value or whether or not the rainfall is equal to or higher than a threshold value), and if the vehicle outside temperature is equal to or higher than the temperature threshold value (or the vehicle speed is equal to or higher than the vehicle speed threshold value or the rainfall is equal to or higher than the threshold value), the process proceeds to step S119 ', whereas if this is not the case, the process proceeds to step S116 '.

The appended claims and their equivalents are intended to cover all such modifications, substitutions and changes as fall within the true scope and spirit of the invention.
