[0032] The following will clearly and thoroughly describe the technical solutions in this application in conjunction with the accompanying drawings. In the description of the embodiments of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of this application, "multiple" means two or more than two.

[0033] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to imply or suggest relative importance or implicitly indicate the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0034] Figure 1 This is a schematic flow chart of a cabin sterilization method provided in an embodiment of the present application.

[0035] For example, Figure 1 As shown, the cabin sterilization method includes the following steps:

[0036] In step S101 , the target sterilization intensity of the cabin is identified.

[0037] Among them, the target sterilization intensity includes a first sterilization intensity and a second sterilization intensity, the second sterilization intensity is higher than the first sterilization intensity, the first sterilization intensity can be the sterilization intensity corresponding to the case of a lower bacterial concentration, and the second sterilization intensity can be the sterilization intensity corresponding to the case of a higher bacterial concentration.

[0038] It is understandable that the embodiments of the present application can identify the target sterilization intensity of the cabin so as to subsequently determine the target source of sterilizing ultraviolet rays in the cabin based on the target sterilization intensity.

[0039] In an embodiment of the present application, identifying the target sterilization intensity of the cabin includes: detecting the bacterial concentration in the cabin; and determining the target sterilization intensity of the cabin according to the bacterial concentration.

[0040] It is understandable that the embodiment of the present application can determine the target sterilization intensity in the cabin based on the bacterial concentration in the cabin.

[0041] Among them, there are many ways to detect the bacterial concentration in the cabin, and comparison is not specifically limited. For example, it can be detected through bacterial concentration detection equipment, or it can be collected through microbial sensors, etc.

[0042] In an embodiment of the present application, the target sterilization intensity of the cabin is determined based on the bacterial concentration, including: if the bacterial concentration is greater than or equal to the first concentration and less than the second concentration, the target sterilization intensity of the cabin is determined to be the first sterilization intensity; if the bacterial concentration is greater than or equal to the second concentration, the target sterilization intensity of the cabin is determined to be the second sterilization intensity.

[0043] The first concentration and the second concentration can be pre-calibrated according to specific circumstances. For example, the first concentration is 100 CFU / m 3 , the second concentration is 300 CFU / m 3 .

[0044] It can be understood that the embodiment of the present application can determine the target sterilization intensity of the cabin to be the first sterilization intensity when the bacterial concentration is greater than or equal to the first concentration and less than or equal to the second concentration, indicating that the bacterial content in the cabin is relatively low at this time and the sterilization intensity is relatively low; when the bacterial concentration is greater than or equal to the second concentration, the target sterilization intensity of the cabin can be determined to be the second sterilization intensity, indicating that the bacterial content in the cabin is relatively high at this time and the sterilization intensity is relatively high.

[0045] It should be noted that when the bacterial concentration is lower than the first concentration, it indicates that the bacterial content in the cabin is trace and no sterilization is required.

[0046] In the embodiment of the present application, before identifying the target sterilization intensity of the cabin, the method further includes: if the vehicle meets the preset sterilization conditions, identifying the target sterilization intensity of the cabin.

[0047] Among them, the preset sterilization conditions include the following: the user has the intention to use the vehicle; the vehicle is parked for longer than a first preset time; there is no one in the vehicle cabin; the actual humidity in the vehicle cabin reaches the target humidity; after the vehicle's air-conditioning system's external circulation mode is turned on for a second preset time, the bacterial concentration is greater than or equal to the first concentration.

[0048] It is understandable that the embodiment of the present application identifies the target sterilization intensity of the cabin only when the vehicle meets the preset sterilization conditions. Conversely, when the preset sterilization conditions are not met, the target sterilization intensity of the cabin is not identified. The preset sterilization conditions include multiple:

[0049] (1) The user has a need for a car;

[0050] (2) The vehicle is parked for a period longer than a first preset period, wherein the first preset period can be set according to specific circumstances, such as seven days or one month, and is not specifically limited thereto;

[0051] (3) There is no one in the vehicle cabin to avoid the harm of ultraviolet rays to the human body;

[0052] (4) The actual humidity in the cabin reaches the target humidity, wherein the target humidity can be set according to the specific situation, such as 50% or 60%, in order to improve the cabin sterilization efficiency, save the user's waiting time and the energy consumption of the whole vehicle. When the humidity is between 50% and 60%, the ultraviolet rays have the highest killing rate for pathogens. Above or below this humidity range, the penetration of ultraviolet rays will decrease, and the sterilization effect may be reduced by 20% to 30%. Therefore, the embodiment of the present application can set a target humidity for the cabin between 50% and 60%. When the actual humidity in the cabin reaches the target humidity, sterilization can be carried out, which can effectively improve the cabin sterilization rate;

[0053] (5) After the vehicle's air conditioning system's external circulation is turned on for a second preset time, the bacterial concentration is greater than or equal to the first concentration. The second preset time can be set according to specific circumstances, such as 3 minutes or 4 minutes, and there is no specific limitation on this. The external circulation mode can also be turned on multiple times, such as 3 times, each time for 3 minutes, so that the external circulation mode of the air conditioning system can be used to circulate first to refresh the air in the cabin, thereby reducing the bacterial content. After the external circulation mode is turned on, if the bacterial concentration is still greater than or equal to the first concentration, the target sterilization intensity of the cabin is identified so that ultraviolet rays can be used to sterilize the cabin later.

[0054] It should be noted that ultraviolet rays are harmful to the human body. Therefore, this application is based on the safety of the user. Therefore, ultraviolet sterilization is only performed when there is no one in the car. When there is someone in the car, the number of bacteria is reduced by updating the air in the car or based on the user's wishes, the user is reminded to leave the cabin, and then the cabin is sterilized.

[0055] In step S102, the target source of the sterilizing ultraviolet rays in the cabin is determined according to the target sterilization intensity.

[0056] The target source of ultraviolet rays includes at least one of ultraviolet rays introduced into the environment by the vehicle and ultraviolet rays generated by an ultraviolet lamp.

[0057] It can be understood that the embodiments of the present application can determine the target source of ultraviolet rays for sterilization in the cabin based on the target sterilization intensity. Specifically, it can determine based on the target sterilization intensity whether the source of ultraviolet rays is ambient ultraviolet rays introduced by the vehicle, ultraviolet rays generated by ultraviolet lamps, or a combination of ambient ultraviolet rays and ultraviolet rays generated by ultraviolet lamps for sterilization, so as to make full use of ultraviolet rays in the environment for cabin sterilization and reduce the energy consumption of the entire vehicle.

[0058] In an embodiment of the present application, the target source of ultraviolet rays for sterilization in the cabin is determined according to the target sterilization intensity, including: if the target sterilization intensity of the cabin is a first sterilization intensity, the target source of ultraviolet rays is determined to be the ultraviolet rays introduced into the environment by the vehicle; if the target sterilization intensity of the cabin is a second sterilization intensity, the target source of ultraviolet rays is determined to be the ultraviolet rays introduced into the environment by the vehicle and the ultraviolet rays generated by the ultraviolet lamp.

[0059] It can be understood that in the embodiment of the present application, when the target sterilization intensity is the first sterilization intensity, that is, the bacterial concentration is low and the sterilization intensity is relatively small, the target source of ultraviolet rays is the ultraviolet rays introduced into the environment by the vehicle, and there is no need to consume the energy of the entire vehicle for sterilization; when the target sterilization intensity is the second sterilization intensity, that is, the bacterial concentration is high and the sterilization intensity is relatively high, the target source of ultraviolet rays is the ultraviolet rays introduced into the environment by the vehicle and the ultraviolet rays generated by the ultraviolet lamp. By combining the environmental ultraviolet rays and the ultraviolet rays of the ultraviolet lamp, the sterilization intensity and sterilization rate are improved.

[0060] In an embodiment of the present application, after determining that the target source of ultraviolet rays is the ultraviolet rays introduced into the environment by the vehicle and the ultraviolet rays generated by the ultraviolet lamp, it also includes: obtaining the correspondence between the bacterial concentration and the number of ultraviolet lamps and the ultraviolet intensity of the ultraviolet lamps; determining the number of ultraviolet lamps and the ultraviolet intensity of the ultraviolet lamps based on the correspondence and the bacterial concentration.

[0061] Among them, the corresponding relationship is the relationship between the bacterial concentration and the number of ultraviolet lamps and the ultraviolet intensity.

[0062] It can be understood that the embodiments of the present application can determine the number and intensity of ultraviolet lamps based on the corresponding relationship and bacterial concentration, so as to flexibly provide different numbers and intensities of ultraviolet lamps for different bacterial concentrations, saving energy consumption of the entire vehicle and effectively improving the sterilization rate.

[0063] In an embodiment of the present application, obtaining a correspondence between the bacteria concentration and the number of ultraviolet lamps and the ultraviolet intensity of the ultraviolet lamps includes: if the bacteria concentration is greater than or equal to the second concentration and less than the third concentration, the number of ultraviolet lamps is the first number, and the ultraviolet intensity of the ultraviolet lamps is the first intensity; if the bacteria concentration is greater than or equal to the third concentration and less than or equal to the fourth concentration, the number of ultraviolet lamps is the second number, and the ultraviolet intensity of the ultraviolet lamps is the first intensity, wherein the second number is greater than the first number; if the bacteria concentration is greater than the fourth concentration, the number of ultraviolet lamps is the second number, and the ultraviolet intensity of the ultraviolet lamps is the second intensity, wherein the second intensity is higher than the first intensity.

[0064] The third concentration and the fourth concentration can be pre-calibrated according to the specific situation. For example, the third concentration is 600 CFU / m 3 , the fourth concentration is 1000 CFU / m 3 ; The number and intensity of ultraviolet lamps can be set according to specific circumstances and are not specifically limited. For example, the total number of ultraviolet lamps is 2, the first number is 1, the second number is 2, the first intensity is 50%, and the second intensity is 100%.

[0065] It is understandable that in the embodiments of the present application, different bacterial concentrations correspond to different numbers and intensities of ultraviolet lamps, so as to select the appropriate sterilization intensity based on the bacterial concentration and improve the sterilization efficiency.

[0066] For example, the second concentration is 300 CFU / m 3 , the third concentration is 600 CFU / m 3 , the fourth concentration is 10000 CFU / m 3 For example, the first quantity is 1 UV lamp, the second is 2 UV lamps, the first intensity is 50%, and the second intensity is 100%;

[0067] If the current bacterial concentration is 350 CFU / m 3 Based on the corresponding relationship, it can be determined that there is 1 UV lamp at this time and the UV intensity is 50%;

[0068] If the current bacterial concentration is 650 CFU / m 3 Based on the corresponding relationship, it can be determined that there are two UV lamps at this time, and the UV intensity of the two UV lamps is 50%;

[0069] If the current bacterial concentration is 1100 CFU / m 3 Based on the corresponding relationship, it can be determined that there are two ultraviolet lamps at this time, and the ultraviolet intensity of the two ultraviolet lamps is 100%.

[0070] In step S103 , the cabin is sterilized based on ultraviolet rays from a target source.

[0071] It can be understood that the embodiments of the present application can sterilize the cabin based on ultraviolet rays from a target source, and combine ambient ultraviolet rays with ultraviolet rays generated by ultraviolet lamps to efficiently sterilize the cabin and improve the cabin air quality.

[0072] The cabin sterilization method of the embodiment of the present application is described below through a specific embodiment.

[0073] First, there is an intelligent adjustment structure in the cabin, which is mainly composed of air side, water side and intelligent sharing mechanism. The intelligent sharing mechanism is integrated with the air side and water side. The intelligent sharing mechanism is designed with hollow blades, which can rotate within the range of -90°-+90°, and can spray the humidifier quickly and evenly into the cabin. Figure 2 As shown, it supports separate humidification of the front and rear rows or simultaneous humidification, and the angle of the blades can be adjusted to introduce ultraviolet rays in the environment.

[0074] There is a UV light strip at the front and rear roof positions of the cabin, UV light 1 (front) and UV light 2 (rear). Figure 3 As shown, first, ultraviolet rays from the environment are introduced into the cabin. If the ultraviolet intensity meets the sterilization requirements, the cabin is sterilized. If it does not meet the requirements, ultraviolet lamp 1 and ultraviolet lamp 2 are turned on according to the needs to achieve the rapid sterilization function of the cabin.

[0075] This application can control the above-mentioned intelligent sharing mechanism and ultraviolet lamp based on the cabin sterilization method to achieve cabin sterilization. The specific process of the cabin sterilization strategy (i.e. the cabin sterilization method of this application) is as follows: Figure 4 As shown, the following steps are included:

[0076] 1. Determine whether the customer has car usage needs.

[0077] 1. Scenario where the customer has no need for a car.

[0078] This method will not be executed if there is no demand. If there is no demand, it will detect whether the vehicle has been parked continuously for more than 7 days. If it does not exceed 7 days, the strategy does not need to be executed. If it exceeds 7 days, it is necessary to detect whether the bacteria in the cabin exceeds the standard. If it does not exceed the standard, the strategy does not need to be executed. If the bacteria exceed the standard, the mobile phone APP will remind the customer whether to deal with it. If the customer chooses not to deal with it, the strategy will not be executed. If the customer chooses to deal with it, the remote start sterilization strategy will be entered.

[0079] 2. Customers have a need for cars.

[0080] When a customer needs to use the vehicle, the system will check whether the bacteria level in the cabin exceeds the standard. If it does not exceed the standard, there is no need to implement this strategy. If it exceeds the standard, the system will check whether there are passengers in the car. If there are passengers in the cabin, the air conditioning system will start the external circulation mode for 3 minutes and cycle 3 times to check whether the bacteria level in the cabin exceeds the standard. If it does not exceed the standard, the cycle will be stopped and the customer will use the vehicle normally. If the bacteria level exceeds the standard, the car system will remind the customer whether to deal with the bacteria level. If the customer chooses not to deal with it, the status quo will be maintained. If the customer chooses sterilization, the customer will be reminded to leave the cabin and the entire vehicle will be sterilized, entering the remote sterilization control strategy.

[0081] 2. Start sterilization strategy.

[0082] 1. Humidity regulation.

[0083] Entering this strategy, the humidity A in the cabin is collected, and using the humidity adjustment function of the intelligent mechanism, the humidity in the cabin is first adjusted to the most suitable humidity for sterilization, that is, the target humidity, to improve the cabin sterilization efficiency, save customers' waiting time and vehicle energy consumption.

[0084] (1) Cabin humidity: 0%<A<30%, start the front row + rear row humidification mode. In this mode, the humidification demand is the highest, and both humidification systems are turned on at the same time to ensure efficient humidification;

[0085] (2) Cabin humidity: 30% ≤ A < 50%, start the front row humidification mode. In this mode, the humidification demand is relatively low, and turning on a single humidification system can meet the humidification demand;

[0086] (3) Cabin humidity: A>60%. This mode belongs to the cabin humidity is high. The current strategy is to turn on the external circulation mode of the air conditioning system to circulate the air in the cabin with the external air to reduce the cabin air humidity, combined with the humidity control strategy until it is adjusted to the target humidity.

[0087] 2. Cabin sterilization.

[0088] The cabin humidity has met the target humidity: 50% ≤ A ≤ 60% is the optimal range, and the cabin bacterial count (ΔT (CFU / m 3), the goal is cabin bacteria condition △T<100CFU / m 3 .

[0089] (1) Cabin bacteria condition: 100≤△T<300.

[0090] In this mode, the demand for sterilization in the cabin is relatively low. At this time, the intelligent sharing mechanism of the skylight system is used to adjust the blade angle and introduce ultraviolet rays in the environment to sterilize the cabin. This does not require additional energy consumption of the entire vehicle, thereby reducing the energy consumption of the entire vehicle.

[0091] (2) Cabin bacteria condition: 300≤△T<600.

[0092] 1) Adjust the blade angle to introduce ambient ultraviolet light;

[0093] 2) UV lamp 1, intensity 50%.

[0094] In this mode, cabin sterilization demand is low. Simply introducing ambient UV light to sterilize the cabin is insufficient. Increasing the number of UV sources and controlling UV intensity (power) can effectively improve the sterilization rate. Start UV Lamp 1 at 50% intensity to sterilize the cabin.

[0095] (3) Cabin bacteria condition: 600≤△T≤1000.

[0096] 1) Adjust the blade angle to introduce ambient ultraviolet light;

[0097] 2) UV lamp 1, intensity 50%;

[0098] 3) UV lamp 2, intensity 50%;

[0099] In this mode, cabin sterilization requirements are high. Simply introducing ambient UV light is insufficient. Increasing the number of UV sources and controlling UV intensity (power) can effectively improve the sterilization rate. Start UV Lamp 1 at 50% intensity and UV Lamp 2 at 50% intensity to sterilize the cabin.

[0100] (4) Cabin bacteria condition △T>1000.

[0101] 1) Adjust the blade angle to introduce ambient ultraviolet light;

[0102] 2) UV lamp 1, intensity 100%;

[0103] 3) UV lamp 2, intensity 100%.

[0104] In this mode, cabin sterilization is most demanding. Simply introducing ambient UV light is insufficient. Increasing the number of UV sources and controlling UV intensity (power) can effectively improve the sterilization rate. Start UV Lamp 1 at 100% intensity and UV Lamp 2 at 100% intensity to sterilize the cabin.

[0105] According to the cabin sterilization method proposed in the embodiment of the present application, the target source of ultraviolet rays for sterilization in the cabin can be determined according to the target sterilization intensity of the cabin, and the ultraviolet rays introduced from the environment and the ultraviolet rays generated by the ultraviolet lamp can be combined. Based on the specific target sterilization intensity, the target source of ultraviolet rays is determined to be the ultraviolet rays introduced from the environment by the vehicle, the ultraviolet rays generated by the ultraviolet lamp, or a combination of the two. The cabin is sterilized based on the target source of ultraviolet rays, thereby efficiently sterilizing the cabin and improving the cabin air quality. In addition, the ultraviolet rays introduced from the environment can reduce the utilization of ultraviolet lamps to a certain extent, thereby reducing the consumption of the entire vehicle and saving energy.

[0106] Next, the cabin sterilization device of the present application will be described with reference to the accompanying drawings.
