[0047] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0048] The method embodiment provided in this embodiment can be executed in a terminal, a computer or a similar computing device. For example, running on a terminal, Figure 1 This is a hardware structure block diagram of a terminal of a vehicle interior anti-mildew method according to an embodiment of the present application. Figure 1 As shown, the terminal may include one or more ( Figure 1 Only one is shown) a processor 102 and a memory 104 for storing data, wherein the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA. The above terminal may also include a transmission device 106 and an input and output device 108 for communication functions. It will be understood by those skilled in the art that Figure 1The structure shown is only for illustration and does not limit the structure of the above terminal. Figure 1 More or fewer components than shown, or with Figure 1 Different configurations shown.

[0049] Memory 104 can be used to store computer programs, such as software programs and modules for application software, such as the computer program corresponding to the vehicle interior mold prevention method in this embodiment. Processor 102 executes the computer program stored in memory 104 to execute various functional applications and data processing, thereby implementing the above-mentioned method. Memory 104 may include high-speed random access memory (RAM) and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, memory 104 may further include memory remotely located relative to processor 102, and such remote memory may be connected to the terminal via a network. Examples of such networks include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0050] The transmission device 106 is used to receive or send data via a network. The network may include a wireless network provided by the terminal's telecommunications provider. In one embodiment, the transmission device 106 includes a network interface controller (NIC), which can be connected to other network devices via a base station to enable communication with the Internet. In another embodiment, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0051] In one embodiment, Figure 2 As shown, a method for preventing mold from forming on vehicle interior is provided. Figure 1 The following steps are used as an example to illustrate the terminal in the figure:

[0052] Step S202: If the vehicle is turned off after driving and the duration of the engine being turned off is greater than or equal to a first time length, the humidity and weather conditions inside the vehicle are obtained during the duration of the engine being turned off.

[0053] The vehicle's engine may be stopped if the vehicle stalls after driving. If the engine stalls for a period of time greater than or equal to a first duration, the vehicle may be parked for an extended period, indicating the possibility of mold in the vehicle interior. The vehicle's interior humidity may include, but is not limited to, one or more of the following parameters: interior humidity and air humidity. Weather conditions may include, but are not limited to, one or more of the following parameters: temperature, humidity, cloud cover, and precipitation.

[0054] Optionally, during the duration of the engine being turned off, the humidity inside the vehicle is obtained via one or more sensors located inside the vehicle. The vehicle's location during the duration of the engine being turned off is obtained, and the weather conditions at the vehicle's location are obtained via a network. The humidity and weather conditions inside the vehicle can be obtained in real time, or multiple times at equal or different time intervals.

[0055] In step S204 , coefficients influencing interior mold are obtained according to the humidity, weather conditions, and engine shutdown time inside the vehicle, and the coefficients are integrated.

[0056] As the humidity inside the vehicle increases, the likelihood of interior mold increases; as the temperature, humidity, or precipitation in the weather conditions increase, the likelihood of interior mold also increases. The probability of interior mold and the coefficient can be positively or negatively correlated. One or more coefficients can be derived based on the humidity inside the vehicle. For example, after obtaining the humidity inside multiple vehicles at preset time intervals, multiple corresponding coefficients can be derived based on the humidity inside the multiple vehicles. Similarly, one or more coefficients can also be derived based on the weather conditions, which will not be detailed here.

[0057] Optionally, to obtain multiple coefficients, mapping relationships between humidity, one or more parameters of weather conditions, and the duration of engine shutdown and the coefficients can be set separately. Alternatively, different weights can be assigned to the coefficients corresponding to vehicle interior humidity, weather conditions, and duration of engine shutdown, and the coefficients can be integrated through weighted summation. Alternatively, the coefficients can be integrated by performing mathematical processing such as addition or multiplication based on a preset formula.

[0058] Step S206 : If the value of the integrated coefficient is within a preset threshold range, the air conditioning system inside the vehicle and / or the heating system of the vehicle interior are started.

[0059] Among them, if the value of the integrated coefficient is within the preset threshold range, it indicates that the probability of interior mold is high, and it is necessary to reduce the possibility of interior mold by heating, dehumidification, etc. The preset threshold range is obtained according to the correlation between the coefficient and the possibility of interior mold and the coefficient integration method, and can be modified according to application requirements. For example, when the coefficient and the possibility of interior mold are positively correlated, and the integrated coefficient is obtained by summing, if the sum of the coefficients is greater than or equal to the specified threshold, it can be judged that the value of the integrated coefficient is within the preset threshold range. When the coefficient and the possibility of interior mold are negatively correlated, and the integrated coefficient is obtained by summing, if the sum of the coefficients is less than or equal to the specified threshold, it can be judged that the value of the integrated coefficient is within the preset threshold range.

[0060] Optionally, upon determining that the integrated coefficient value is within a preset threshold range, the air conditioning system may implement one or more of the following functions: heating the vehicle interior air, reducing the vehicle interior humidity through a dehumidification mode; and simultaneously, activating the heating system to heat at least a portion of the vehicle interior. It is understood that it is also possible to activate only the air conditioning system or only the interior heating system.

[0061] In the above-mentioned vehicle interior mold prevention method, the coefficient affecting the risk of interior mold is obtained by obtaining the humidity and weather conditions inside the vehicle during the continuous vehicle shutdown time. The air conditioning system inside the vehicle and / or the heating system of the vehicle interior are activated according to the coefficient to reduce the possibility of interior mold, thereby solving the problem of vehicle interior being prone to mold.

[0062] In one embodiment, a coefficient affecting interior mold is obtained based on the humidity inside the vehicle, including: obtaining the humidity of the air inside the vehicle based on a preset time interval during the continuous engine off time; comparing the humidity of the air inside the vehicle with a first threshold; and obtaining a second coefficient corresponding to the humidity inside the vehicle based on the number of times the humidity of the air inside the vehicle is greater than or equal to the first threshold and a preset weight corresponding to the number of times.

[0063] The preset time interval may be a fixed value or a variable value determined by a setting. One or more sensors may be installed inside the vehicle, and the one or more sensors may obtain humidity readings of the air inside the vehicle multiple times based on the preset time intervals. The first threshold value is associated with the material of the vehicle interior and is used to indicate a high probability of interior mold at the current air humidity. The first threshold value may be determined based on experiments.

[0064] Optionally, each time the humidity of the vehicle's interior air is obtained, the currently obtained humidity is compared with a first threshold. The accumulated number of times the humidity of the vehicle's interior air is greater than or equal to the first threshold is multiplied by a preset weight to obtain a second coefficient. For ease of understanding, for example, the second coefficient is initially set to zero and the preset weight is set to 0.1. If the humidity of the vehicle's interior air is greater than or equal to the first threshold twice, the number of times the humidity is greater than or equal to the first threshold is multiplied by the preset weight to obtain a second coefficient of 0.2. The initial value and preset weight can be set as needed.

[0065] Optionally, different preset weights may be assigned to different times. For ease of understanding, for example, if the humidity of the air inside the vehicle is greater than or equal to the first threshold two times, a weight of 0.2 is assigned; if the humidity of the air inside the vehicle is greater than or equal to the first threshold three times, a weight of 0.5 is assigned.

[0066] In this embodiment, the coefficient affecting vehicle mold is determined by the accumulated humidity inside the vehicle. Taking into account the impact of changes in air humidity on the mold risk, dynamic detection of interior mold risk is achieved, thereby improving the accuracy of judgment.

[0067] In one embodiment, a coefficient affecting interior mold is obtained based on the humidity inside the vehicle, including: obtaining the humidity of the vehicle interior during the continuous engine-off time and the humidity balance point of the vehicle interior; if the humidity of the vehicle interior is greater than or equal to the humidity balance point, adjusting a first coefficient corresponding to the humidity inside the vehicle so that the value of the integrated coefficient is within a preset threshold range.

[0068] The humidity balance point refers to the relative humidity when the material and the moisture in the surrounding environment reach a dynamic equilibrium at a specific temperature. Optionally, the humidity balance point is obtained based on the material of the interior and the temperature inside the vehicle. When the humidity of the vehicle interior is greater than or equal to the humidity indicated by the humidity balance point, the risk of interior mold is higher. Optionally, when there is a positive correlation between the coefficient and the possibility of interior mold, and the integrated coefficient is obtained by summing, the first coefficient is set to a value exceeding a preset threshold range, so that the air conditioning system inside the vehicle and / or the heating system of the vehicle interior is started. In this embodiment, considering that the humidity of the interior directly affects the degree of interior mold, the effect of accurately judging the risk of interior mold is achieved by comparing the humidity balance point and the humidity of the vehicle interior.

[0069] In one embodiment, obtaining a coefficient affecting interior mold based on weather conditions includes: obtaining the cumulative time during which the weather conditions meet a preset weather condition during the continuous engine shutdown time; and obtaining a coefficient corresponding to the weather condition based on the cumulative time.

[0070] The preset weather state may be one or more of the following states: a rainy state, a state in which the humidity is greater than a specified value, and a state in which the temperature is within a specified range. Taking the preset weather state as an example of a rainy state, optionally, the cumulative time of rainfall within the continuous engine shutdown time is obtained; the mapping relationship between the cumulative rainfall time and the coefficient corresponding to the weather state is obtained; and the corresponding coefficient is obtained by mapping the cumulative time based on the mapping relationship. For example, the rainfall time of a preset time length is used as a base unit, a corresponding value is set for the base unit, and the effect of rainfall on the change of the interior state is quantified based on these base units and the corresponding values ​​to obtain the coefficient corresponding to the weather state. If the effect of the rainfall time of each base unit on the change of the interior state is fixed, then the coefficient corresponding to the weather state can be calculated by multiplying the number of base units and the corresponding value.

[0071] This embodiment takes into account the possibility that weather conditions may change over time and the impact of weather conditions on the vehicle interior environment, and determines the coefficient corresponding to the weather conditions based on the accumulated time to improve the accuracy of the judgment of interior mold risk.

[0072] In one embodiment, obtaining a coefficient affecting interior mold based on the continuous engine-off time includes: removing a first time length from the continuous engine-off time to obtain a second time length; and obtaining a coefficient corresponding to the continuous engine-off time based on the second time length.

[0073] Among them, when the probability of interior mold and the coefficient are positively correlated, the longer the second time length, the larger the coefficient corresponding to the continuous flameout time; and vice versa. When the probability of interior mold and the coefficient are negatively correlated, the longer the second time length, the smaller the coefficient corresponding to the continuous flameout time; and vice versa. The mapping relationship between the coefficient corresponding to the continuous flameout time and the second time length can be set according to needs. When the continuous flameout time is greater than or equal to the first time length, the vehicle interior may begin to mold. This embodiment uses the first time length as the benchmark time length, and removing the first time length on the basis of the continuous flameout time can more clearly measure the impact of exceeding the benchmark time length on the change in the interior state, thereby facilitating accurate judgment of the impact of the continuous flameout time on the mold of the vehicle interior.

[0074] In one embodiment, if the vehicle is turned off after driving and the continuous off time is greater than or equal to a first time length, then before obtaining the humidity balance point of the vehicle interior, the humidity inside the vehicle, and the weather conditions during the continuous off time, the method also includes: when the vehicle is turned off after driving, obtaining the humidity of the vehicle interior and the humidity balance point of the vehicle interior; if the humidity of the vehicle interior is greater than or equal to the humidity balance point, starting the air conditioning system inside the vehicle and / or the heating system of the vehicle interior.

[0075] Optionally, the vehicle interior humidity balance point is determined based on the interior material and the current vehicle interior temperature, and the vehicle interior humidity is compared with the humidity balance point. If the vehicle interior humidity is greater than or equal to the humidity balance point, a preset message may be sent to the user, activating the vehicle's air conditioning system and / or the vehicle interior heating system based on the user's selection.

[0076] In this embodiment, by comparing the vehicle interior humidity with the vehicle interior's equilibrium humidity point, the humidity and / or temperature inside the vehicle can be adjusted promptly to prevent mold growth on the interior surface, such as in the event of spillage or water intrusion. Furthermore, when the vehicle is parked after driving and the engine is turned off, interior humidity monitoring and activation of the vehicle's air conditioning system and / or interior heating system ensure that humidity control does not affect normal vehicle operation.

[0077] In one embodiment, before starting the air conditioning system inside the vehicle and / or the heating system of the vehicle interior, the method further comprises: in the case that the vehicle comprises an internal combustion engine, judging whether the surrounding environment where the vehicle is located meets the starting requirement of the air conditioning system inside the vehicle and / or the heating system of the vehicle interior; in the case that the vehicle comprises an electric motor, judging whether the battery power of the vehicle meets the starting requirement of the air conditioning system inside the vehicle and / or the heating system of the vehicle interior.

[0078] In one embodiment, before starting the air conditioning system inside the vehicle and / or the heating system of the vehicle interior, the method further comprises: in the case that the vehicle comprises an internal combustion engine, judging whether the surrounding environment where the vehicle is located meets the starting requirement of the air conditioning system inside the vehicle and / or the heating system of the vehicle interior; in the case that the vehicle comprises an electric motor, judging whether the battery power of the vehicle meets the starting requirement of the air conditioning system inside the vehicle and / or the heating system of the vehicle interior.

[0079] In one embodiment, before starting the air conditioning system inside the vehicle and / or the heating system of the vehicle interior, the method further comprises: in the case that the vehicle comprises an internal combustion engine, judging whether the surrounding environment where the vehicle is located meets the starting requirement of the air conditioning system inside the vehicle and / or the heating system of the vehicle interior; in the case that the vehicle comprises an electric motor, judging whether the battery power of the vehicle meets the starting requirement of the air conditioning system inside the vehicle and / or the heating system of the vehicle interior.

[0080] In one embodiment, before starting the air conditioning system inside the vehicle and / or the heating system of the vehicle interior, the method further comprises: in the case that the vehicle comprises an internal combustion engine, judging whether the surrounding environment where the vehicle is located meets the starting requirement of the air conditioning system inside the vehicle and / or the heating system of the vehicle interior; in the case that the vehicle comprises an electric motor, judging whether the battery power of the vehicle meets the starting requirement of the air conditioning system inside the vehicle and / or the heating system of the vehicle interior.

[0081] In one embodiment, before starting the air conditioning system inside the vehicle and / or the heating system of the vehicle interior, the method further comprises: in the case that the vehicle comprises an internal combustion engine, judging whether the surrounding environment where the vehicle is located meets the starting requirement of the air conditioning system inside the vehicle and / or the heating system of the vehicle interior; in the case that the vehicle comprises an electric motor, judging whether the battery power of the vehicle meets the starting requirement of the air conditioning system inside the vehicle and / or the heating system of the vehicle interior. In one embodiment, before starting the air conditioning system inside the vehicle and / or the heating system of the vehicle interior, the method further comprises: in the case that the vehicle comprises an internal combustion engine, judging whether the surrounding environment where the vehicle is located meets the starting requirement of the air conditioning system inside the vehicle and / or the heating system of the vehicle interior; in the case that the vehicle comprises an electric motor, judging whether the battery power of the vehicle meets the starting requirement of the air conditioning system inside the vehicle and / or the heating system of the vehicle interior.

[0082] The second threshold is a humidity value in an environment where the interior is less susceptible to mold, and the third threshold is a temperature value in an environment where the interior is less susceptible to mold. Optionally, after the vehicle interior humidity is greater than or equal to the humidity equilibrium point, the vehicle interior humidity is obtained after the vehicle interior air conditioning system and / or vehicle interior heating system is activated. If it is determined that the vehicle interior humidity has dropped below the second threshold, the vehicle interior air conditioning system and / or vehicle interior heating system is deactivated. After the vehicle interior air conditioning system and / or vehicle interior heating system is activated because the integrated coefficient value is within a preset threshold range, the vehicle interior air temperature is obtained. If it is determined that the air temperature has risen above the third threshold, the vehicle interior air conditioning system and / or vehicle interior heating system is deactivated.

[0083] Furthermore, the air conditioning system inside the vehicle and / or the heating system of the vehicle interior can be started within a specified time period. During the process of starting the air conditioning system and / or the heating system, the heating time is corrected according to the interior humidity and the air humidity in the vehicle until the interior humidity is less than or equal to a second threshold.

[0084] In this embodiment, whether the risk of interior mold is low is accurately determined based on the temperature and / or humidity, and the air conditioning system inside the vehicle and / or the heating system of the vehicle interior are stopped to reduce energy loss.

[0085] In one embodiment, coefficients influencing interior mold are obtained based on the humidity, weather conditions, and continuous engine-off time inside the vehicle, including: obtaining a parking position of the vehicle; and adjusting, based on the parking position, the coefficients influencing interior mold obtained based on the humidity, weather conditions, and continuous engine-off time inside the vehicle.

[0086] The parking location can be the latitude and longitude of the vehicle. The risk of mold growth in vehicle interiors can be affected by factors such as climate and human activity in different regions. The parking location can also be the geographic location of the vehicle relative to the surrounding environment. The risk of mold growth in vehicle interiors can also be affected by factors such as ventilation conditions and industrial emissions. Optionally, one or more coefficients influenced by vehicle interior humidity, weather conditions, and engine shutdown duration can be modified based on the parking location, including by increasing or decreasing the coefficient values.

[0087] In this embodiment, the accuracy of the interior mold risk judgment can be improved according to the vehicle parking position adjustment coefficient.

[0088] In one embodiment, before starting the air conditioning system inside the vehicle and / or the heating system of the vehicle interior, preset information can be sent to the user terminal for confirmation, and in response to the instructions of the user terminal, it is determined whether to start the air conditioning system inside the vehicle and / or the heating system of the vehicle interior.

[0089] In one embodiment, considering that a moldy vehicle may produce an odor in the vehicle interior, whether to activate external circulation and / or open the windows can be determined based on the operating status of the heating and / or air conditioning systems, the vehicle's parking location, and weather conditions. Optionally, activation of external circulation and / or opening of the windows to dissipate odor from the vehicle interior can be performed under one or more of the following conditions: the heating and / or air conditioning systems are operating; the vehicle is parked in an open area; and the weather is clear and the ambient light intensity is greater than a specified value.

[0090] This embodiment accelerates the dissipation of odors in the car by heating the interior, thereby solving the problem of moldy vehicles emitting odors or new cars emitting odors due to materials such as adhesives and asphalt vibration damping plates used in the manufacturing process, avoiding allergies caused by odors in some people, and the problem of reduced vehicle value.

[0091] In one embodiment, Figure 3 A vehicle system is provided, such as Figure 3 As shown, the vehicle system includes a first humidity sensor, a second humidity sensor, a temperature sensor, a weather forecast system, a heating system, an air conditioning system, a window control system, an indoor and outdoor circulation system, and a control system.

Specifically, the first humidity sensor is used to detect the humidity of mold-prone interior trim; the second humidity sensor is used to detect the humidity of the air inside the vehicle. The temperature sensor is used to detect the temperature of the air inside the vehicle. The weather forecast system is used to obtain the cumulative rainfall duration at the vehicle's location.

[0093] The heating and air conditioning systems are used to adjust the humidity inside the vehicle. Specifically, the heating system includes electric heating wires that heat the vehicle's interior, which is prone to mold, thereby reducing the humidity inside the vehicle. The air conditioning system is used to heat the vehicle interior. Optionally, the air conditioning system can be modified to increase the upper temperature limit, for example, from 30°C to 55°C. The window control system and the interior and exterior circulation system are used to help dissipate odors inside the vehicle.

[0098] Step S403: After sending the preset information to the user and obtaining the user's confirmation, the interior heating system is activated, and the heating time is estimated based on the humidity of the interior and the heating power of the heating system.

[0101] Optionally, during step S403, the humidity outside the vehicle may be detected. If the humidity inside the vehicle exceeds W, external circulation may be activated to reduce the humidity inside the vehicle. W may be set as required. Optionally, a temperature sensor may be provided to obtain the humidity outside the vehicle. If the humidity inside the vehicle is higher than the humidity outside the vehicle, external circulation may be activated.

[0107] Optionally, the coefficient n corresponding to the cumulative number of parking days is calculated as follows:

[0108] n = (accumulated number of days of parking - first time length) / 10;

[0109] The value 10 indicates the weight of the cumulative parking days on mold risk. The value of 10 in the coefficient n calculation formula can be modified as needed. A larger value may reduce the weight of the cumulative parking days on the mold risk assessment; conversely, a smaller value may increase the weight of the cumulative parking days on the mold risk assessment. The first time period can be set to 3 days or any other value.

[0110] The calculation method of the coefficient m corresponding to the humidity of the vehicle interior is: if the humidity of the vehicle interior is greater than or equal to the interior humidity balance point, the coefficient m is recorded as 1; if the humidity of the vehicle interior is less than the interior humidity balance point, the coefficient m is recorded as 0

[0111] The coefficient p corresponding to the humidity of the air inside the vehicle is calculated as follows: the humidity of the air inside the vehicle is obtained every other day, and each time it is determined that the humidity of the air inside the vehicle is greater than or equal to a first threshold value P, the coefficient p is increased by 0.1.

[0112] The coefficient q corresponding to the cumulative rainfall duration is calculated as follows: taking 10 hours of rainfall as a base unit, multiplying the number of base units obtained by the cumulative rainfall duration by a preset weight to obtain the coefficient q.

[0113] The integrated coefficient K = n + m + p + q. The threshold range is greater than or equal to 1. It is understandable that the coefficient acquisition and integration methods can be modified, and the threshold range can be modified accordingly according to needs.

[0114] Step S505 , after sending the preset information to the user and obtaining the user's confirmation, the air conditioning system and the heating system of the vehicle are operated.

[0115] Step S506: If the vehicle interior temperature remains above or equal to a third threshold for a predetermined period of time, the air conditioning system and the heating system are turned off. Alternatively, the vehicle air conditioning system heats the air at 55 degrees Celsius and simultaneously activates the vehicle heating system. If the vehicle interior temperature remains above or equal to the third threshold for 20 minutes, the air conditioning system and the heating system are turned off. The predetermined maintenance period may also be set to other values.

[0116] Among them, the preset operating time of the vehicle's air-conditioning system and heating system can be calculated based on the dehumidification amount and the dehumidification amount of the air-conditioning system and heating system.

[0117] According to the humidity of the air in the vehicle and the third threshold value, the required dehumidification amount W1 of the vehicle is calculated:

[0118] W1 = V x P x (X2 - X1) ÷ 1000 x 1.2 (kg / h)

[0119] wherein W1 is the required dehumidification amount (unit, kg / h); V is the volume of the interior space of the vehicle (unit, m 3 ); P is the air density (unit, kg / m 3 ), generally taken as 1.2 as an approximate value; X2 is the absolute humidity of the air in the vehicle before dehumidification (unit, g / m 3 ); X1 is the absolute humidity of the air after dehumidification (unit, g / m 3 ), i.e. the third threshold value; 1.2 is a safety factor for considering the loss and efficiency in the actual dehumidification process.

[0120] The moisture mass W2 heated and dehumidified by the interior heating system per hour is obtained:

[0121] W2 = G (ω1 - ω2) / (1 - ω2)

[0122] wherein W2 is the mass of the moisture evaporated from the interior per hour (unit, kg / h); G is the moisture treatment amount of the heating system per hour (unit, kg / h); ω1 is the initial moisture content of the interior, which is obtained according to the humidity of the vehicle interior; ω2 is the moisture content after drying of the interior, which is obtained according to the second threshold value.

[0123] The dehumidification amount W3 of the air conditioning system per hour is obtained:

[0124] W3 = V x (W in - W out ) x 10-3

[0125] wherein V˙ is the volume flow rate of the air (unit, m 3 / h); Win is the absolute humidity of the air inlet of the air conditioning system (unit, g / m 3 ); W out is the absolute humidity of the air outlet of the air conditioning system (unit, g / m 3 ).

[0126] According to W1, W2 and W3, the preset running time of the air conditioning system and the heating system can be determined.

[0127] Optionally, when the user selects the odor volatilization mode, if the heating system is in the state of heating the interior; or, the vehicle's GPS (Global Positioning System) and camera capture the vehicle's position as being inside the garage; or, the vehicle's GPS and camera capture the vehicle's position as being outside the garage, the weather forecast shows sunny days, and the light sensor measures the ambient light intensity as being greater than a specified value, the window control system can be controlled to open the window gaps and / or the vehicle's interior and exterior circulation system can be controlled to turn on the exterior circulation mode.

[0128] Optionally, before executing step S505 or executing step S403, if the vehicle is a new energy vehicle, a determination is made as to whether the vehicle battery's power level supports the operation of the heating system and / or air conditioning system. If so, the vehicle interior mold prevention method is executed. If the vehicle is a fuel vehicle, a camera in the vehicle is used to confirm whether the vehicle's environment supports the operation of the heating system and / or air conditioning system. If so, the engine is started and the vehicle interior mold prevention method is executed. Confirming the vehicle's environment through the vehicle's camera includes: if the vehicle is located in a single-room garage, determining that the vehicle's exhaust cannot be discharged normally and that the environment does not support the operation.

[0129] This embodiment continuously monitors interior humidity and air humidity to determine the humidity level inside the vehicle. It intelligently determines the risk of mold inside and outside the interior based on the interior humidity, and the risk of mold outside the interior based on the air humidity. Combined with collected environmental parameters such as weather conditions, it intelligently decides whether to activate the heating system and circulation mode, effectively eliminating the chain of interior mold and fundamentally resolving the problem of moisture-related mold in vehicle interiors. Furthermore, the heating and air conditioning systems not only prevent mold but also accelerate the dissipation of chemical odors from new car interiors, reducing the intensity of the odor.
