DETAILED DESCRIPTION

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0019] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] Example 1 Please refer to Figure 1 This embodiment provides a method for controlling mildew odor of a vehicle air conditioner, comprising: S1: When it is determined that the vehicle is locked and the air conditioning is turned on within a first set time before the vehicle is powered off, environmental data is obtained, where the environmental data at least includes the ambient temperature, the evaporator surface temperature and the humidity in the vehicle; S2: Determine the musty odor risk level according to the environmental data; S3: calling a first control database according to the musty smell risk level to obtain an operating gear and an operating time of the blower, wherein the first control database includes a plurality of musty smell risk levels and the operating gear and the operating time corresponding to each musty smell risk level; S4: controlling the blower to perform mildew prevention according to the operating gear and the operating time.

[0021] Specifically, a vehicle using the control method provided in this embodiment includes at least an ambient temperature sensor, an evaporator temperature sensor and a humidity sensor, wherein the ambient temperature sensor is arranged outside the vehicle to detect the ambient temperature outside the vehicle, the evaporator temperature sensor is arranged on the surface of the evaporator to detect the temperature of the evaporator surface, and the humidity sensor is arranged inside the vehicle to detect the humidity inside the vehicle.

[0022] In step S1, after the driver and passengers get off the vehicle and lock the vehicle, the vehicle is judged to be powered off and the air conditioning has been started within a first set time period before the power-off moment, indicating that there may be water droplets formed by condensation on the surface of the evaporator. At this time, environmental data is obtained through the ambient temperature sensor, the evaporator temperature sensor and the humidity sensor. The environmental data in this embodiment includes three types: ambient temperature, evaporator surface temperature and humidity in the vehicle. Other factors related to mold in the vehicle may also be added in other embodiments.

[0023] In step S2, the risk of mold in the vehicle is predicted based on the environmental data obtained in step S1, and then the moldy smell risk level is obtained; the method for determining the moldy smell risk level includes two implementation methods given here, and the first determination method includes: The ambient temperature, the evaporator surface temperature and the humidity in the vehicle are respectively multiplied by the corresponding calculation weights and then summed to obtain a risk judgment parameter; The musty odor risk level is obtained according to the set range of the risk judgment parameter.

[0024] Specifically, after obtaining the ambient temperature, evaporator surface temperature and in-car humidity, according to the different degrees of influence of the ambient temperature, evaporator surface temperature and in-car humidity on mold in the car, a corresponding weight is preset in advance for each type of environmental data, and each type of environmental data is multiplied by the corresponding weight and then summed up. After summing up, a risk judgment parameter for judging the risk of mold in the car is obtained. There are multiple setting ranges preset in advance for the risk judgment parameter, and the moldy smell risk level is obtained by judging which setting range the risk judgment parameter belongs to. Here, the weights corresponding to the ambient temperature, evaporator surface temperature and in-car humidity are 0.3, 0.2 and 0.5 respectively.

[0025] The second method of determining the risk level of musty odor includes: The musty odor risk level database is consulted according to the ambient temperature, the evaporator surface temperature and the humidity in the vehicle to obtain the musty odor risk level.

[0026] Specifically, after obtaining the ambient temperature, the evaporator surface temperature and the in-vehicle humidity, the musty smell risk level database is called according to the ambient temperature, the evaporator surface temperature and the in-vehicle humidity. The musty smell risk level database includes multiple ambient temperature ranges, multiple evaporator surface temperature ranges, multiple in-vehicle humidity ranges and multiple musty smell risk levels. The musty smell risk level database is shown in Table 1 below: Table 1

[0027] The above Table 1 is only used as an example, and the values ​​of parameters a, b, c, and d can be calibrated according to the specific conditions of the country where the vehicle model is sold. Here, a numerical example is given for parameters a, b, and c: a can be selected as 30°C, b can be selected as 10°C, and c can be selected as 80.

[0028] In step S3, the pre-stored first control database is called according to the moldy smell risk level obtained in step S2. The first control database includes multiple moldy smell risk levels, and each moldy smell risk level corresponds to an operating gear and an operating time of the blower. The first control database is shown in Table 2 below: Table 2

[0029] According to the musty odor risk level, the corresponding operating gear and operating time can be obtained in the first control database; the correspondence between the musty odor risk level, the operating gear and the operating time in the above Table 2 is calibrated in advance according to the type of blower, and each set of correspondence can be regarded as a working strategy of the blower; taking the musty odor risk level of 1 in the above Table 2 as an example, it means that when the musty odor risk level is judged to be 1, it only needs to let the blower run at gear 1 for 10 seconds to dry the water droplets on the evaporator, so there is no need to adjust the blower to the maximum gear to consume unnecessary electricity.

[0030] In step S4, the blower is controlled according to the operating gear and operating time obtained in step S3, so as to effectively prevent mold in the vehicle and reasonably utilize the power of the battery.

[0031] Example 2 Based on the above-mentioned embodiment 1, this embodiment provides a method for controlling mildew odor of a vehicle air conditioner. The same contents as those of the embodiment will not be repeated here. The difference lies in that: After calling the first control database according to the musty smell risk level to obtain the operating gear and operating time of the blower, the method further includes: Get the battery power; When it is determined that the battery power is higher than the set power, a first power difference is calculated according to the battery power and the set power, and the power consumption of the blower when running at the running gear for the running time is calculated; When it is determined that the power consumption is less than or equal to the first power difference, the blower is controlled to perform a mildew prevention action according to the operating gear and the operating time.

[0032] Since the blower is driven by the power of the battery, and the battery is used for other functions besides driving the blower, such as the car engine, lights, etc., especially for fuel vehicles, the battery is also used to drive the vehicle to start, so it is not advisable to let the battery power be too low. Therefore, after obtaining the operating gear and operating time in the above step S3, it is necessary to consider the impact of the battery power. The specific steps are: First, obtain the current battery power, and compare the obtained battery power with the set power preset in advance. The set power is an artificially set power red line. When the battery power is lower than the set power, it indicates that the battery power will affect the normal use of the vehicle; when it is judged that the battery power is higher than the set power, it indicates that the blower can be driven by the battery at this time, but because the battery power will be consumed during the operation of the blower, it is not certain whether the current battery power can support the blower to run at the operating gear for a long time before reaching the set power. Therefore, it is also necessary to calculate the difference between the battery power and the set power, that is, the first power difference. The first power difference can be understood as the power that the battery can still support the blower to work; at the same time, calculate the power consumption of the blower running at the running gear. The power consumption can be obtained by multiplying the power of the blower at the running gear by the running time; When the power consumption is less than or equal to the first power difference, it indicates that the battery can support the blower to complete the work with the current working strategy, and therefore the blower starts to be controlled to work at the current operating gear for a certain operating time.

[0033] Furthermore, the method further comprises: When it is determined that the power consumption is greater than the first power difference, calculating the difference between the power consumption and the first power difference to obtain a second power difference; Calling a gear adjustment database according to the second power difference, the operating gear and the operating duration to obtain a first correction value, wherein the gear adjustment database includes a plurality of second power difference ranges, a plurality of operating gears corresponding to each second power difference range, a plurality of operating durations corresponding to each operating gear, and a first correction value corresponding to each operating duration; The operating gear is corrected according to the first correction value, and the blower is controlled to perform a mildew prevention action according to the operating gear and the operating time.

[0034] When the power consumption is greater than the first power difference, it indicates that the available power in the battery is insufficient to support the blower to complete the work according to the current working strategy. If the blower is operated at the current operating gear, the available power will be exhausted before the blower continues to operate for a long time. The improvement method provided in this embodiment is to reduce the operating gear of the blower so that the blower can continue to operate for as long as possible. The specific method includes: First, the difference between the power consumption and the first power difference is calculated to obtain the second power difference. The second power difference can be understood as the power required for the blower to operate at the operating gear. Then, the gear adjustment database is called according to the second power difference. The gear adjustment database includes multiple ranges of second power differences, multiple operating gears, multiple operating durations, and multiple first correction values. When a group of second power difference ranges, operating gears, and operating durations correspond, a unique first correction value can be obtained. The gear adjustment database is shown in Table 3 below: Table 3

[0035] According to the second power difference range, the operating gear and the operating time, the first correction value can be obtained. The first correction value is the number of gears that need to be reduced. By reducing the operating gear by the first correction value, the blower can maintain the corresponding operating time as much as possible. Correcting the operating gear by the first correction value can ensure that efficient mildew prevention measures are implemented as much as possible under the premise that the battery power allows. It should be noted that the first correction value 1, the second correction value 2, the third correction value 3 and the fourth correction value 4 in the above Table 3 are only used for examples, which may be the same value, and the first correction value 1, the first correction value 2, the first correction value 3 and the first correction value 4 may also be 0. When the first correction value is 0, it may be the case that the operating gear is the lowest gear. In this case, the gear downshift will not be continued, and the blower will be turned off when the current operating gear is operated until the battery power is equal to the set power.

[0036] Furthermore, when it is determined that the battery power is lower than a set power during the operation of the blower, the blower is turned off.

[0037] Furthermore, after obtaining the battery power, the method further includes: When it is determined that the battery power is lower than the set power, the vehicle external circulation is started.

[0038] Specifically, after obtaining the battery power, if the battery power is lower than the set power, it means that the battery power has reached the power red line, so it is not enough to support the start of the blower, so the anti-mildew action cannot be performed through the blower. In this case, the system chooses to start the vehicle's external circulation to reduce the risk of mildew in the car.

[0039] Example 3 This embodiment provides another method for controlling mildew odor of vehicle air conditioner based on the above embodiment. The same contents as those of embodiment 1 or embodiment 2 are not repeated here. The difference is that: Before controlling the blower to perform the mildew prevention action according to the operating gear and the operating time, the method further includes: Obtaining the number of starts of the blower; When it is determined that the number of startups is greater than the set number of startups, a second correction value is calculated according to the number of startups and the set number of startups; The running time is corrected according to the second correction value.

[0040] Considering that the efficiency of the blower will decrease as the blower is used for a longer time, it is possible that even if the blower is operated at the running gear, it will not achieve the optimal mildew prevention effect. Therefore, corrections need to be made before the blower is operated. The specific steps include: First, after the operating gear and operating duration are obtained in the above step S3, the number of starts of the blower is also obtained. Each time the blower is started, the system will accumulate the number of starts of the blower; then the number of starts of the blower is compared with the preset set number. When the number of starts is less than or equal to the set number, it indicates that the blower is still in a relatively new state, and its working efficiency is assumed to be unaffected, and the operating gear and operating duration controller obtained by step S3 will work; when the number of starts is greater than the set number, it indicates that the blower has been used for a long time, and its working efficiency may be reduced by default. At this time, a second correction value is calculated based on the number of starts and the set number, and the second correction value is the ratio of the number of starts to the set number; after obtaining the second correction value, the operating duration is corrected according to the second correction value. The specific correction method is to multiply the second correction value by the operating duration to obtain a new operating duration.

[0041] Example 4 This embodiment provides another method for controlling mildew odor of vehicle air conditioner based on the above embodiment. The same contents as the above embodiment will not be repeated here. The difference lies in that: Before determining the musty smell risk level according to the environmental data, the method further includes: Get the usage time of the ambient temperature sensor used to detect the ambient temperature; When it is determined that the use time of the ambient temperature sensor is greater than the second set time, weather information is retrieved, where the weather information includes the outdoor temperature; When it is determined that the temperature difference between the ambient temperature and the outdoor temperature is greater than a set threshold, the ambient temperature is corrected according to the outdoor temperature.

[0042] In addition to considering the problem of reduced blower efficiency, it is also necessary to consider the accuracy of the ambient temperature sensor detection results. The ambient temperature sensor may decrease in accuracy due to long-term use, or the ambient temperature sensor may be damaged due to being installed outside the vehicle, resulting in decreased accuracy. The decreased accuracy of the ambient temperature sensor will result in inaccurate ambient temperature, which will affect the judgment of the musty odor risk level. Therefore, before judging the musty odor risk level based on environmental data, it is also necessary to judge based on the status of the ambient temperature sensor, including: First, obtain the usage time of the ambient temperature sensor, and compare whether the usage time is greater than the preset second setting time. When the usage time is less than the second preset time, it indicates that the ambient temperature sensor has not lost its accuracy due to long-term use. At this time, the musty odor risk level can be judged according to the detected ambient temperature; when the usage time is greater than the preset second setting time, it indicates that the ambient temperature sensor may have lost its accuracy due to long-term use. At this time, retrieve the weather information of the day. The weather information includes the outdoor temperature at this time. The vehicle needs to be connected to the wireless network when retrieving the weather information; then calculate the temperature difference between the ambient temperature and the outdoor temperature. When the temperature difference is greater than the set threshold, it indicates that the ambient temperature sensor has lost its accuracy. At this time, the outdoor temperature is used instead of the ambient temperature to participate in the judgment of the musty odor risk level, so as to correct the problem of misjudgment caused by the decreased accuracy of the ambient temperature sensor.

[0043] Example 5 This embodiment provides another method for controlling mildew odor of vehicle air conditioner based on the above embodiment. The same contents as the above embodiment will not be repeated here. The difference lies in that: Before determining the musty odor risk level according to the environmental data, the following steps are also included: When it is determined that at least one of the evaporator surface temperature and the in-vehicle humidity is not obtained, obtaining an air-conditioning cooling duration, where the air-conditioning cooling duration is a duration during which the air-conditioning is turned on within the first set duration; The second control database is called according to the air conditioning cooling time to obtain the operating gear and the operating time, wherein the second control database includes a plurality of air conditioning cooling time ranges and the operating gear and the operating time corresponding to each air conditioning cooling time range.

[0044] In addition to considering the possible failure of the ambient temperature sensor, it is also necessary to consider the problem of failure of the evaporator temperature sensor and the humidity sensor. This embodiment considers the situation that the evaporator temperature sensor and the humidity sensor fail to detect the evaporator surface temperature and the temperature inside the vehicle. If at least one of the evaporator surface temperature and the humidity inside the vehicle is missing, it indicates that complete environmental data is missing, so the musty smell risk level cannot be judged. Therefore, other methods are needed to obtain the operating gear and operating time of the blower. The specific methods include: The air conditioning cooling time is obtained, that is, the time during which the air conditioning runs in the cooling mode within the first set time before the vehicle is powered off is determined; then the second control database is called according to the air conditioning cooling time, and the second control database includes multiple air conditioning cooling time ranges, and each air conditioning cooling time range corresponds to an operating gear and an operating time of the blower, and the second control database is shown in Table 4 below: Table 4

[0045] According to the air-conditioning cooling time, the corresponding operating gear and operating time can be obtained in the second control database, and then the control strategy of the blower corresponding to different air-conditioning cooling time can be obtained; it should be noted that the control strategy obtained through the second control database is less effective than the control strategy obtained according to the first control database, so it is used as a backup method.

[0046] Example 6 Based on the same inventive concept, the present invention also provides an air-conditioning anti-mildew odor control system, the principle of which is similar to the principle of any of the above-mentioned vehicle air-conditioning anti-mildew odor control methods, and the repeated parts will not be repeated.
