[0002] The interior of a vehicle is a closed environment with poor air flow, and the quality of the air inside the vehicle needs to be ensured by the vehicle air conditioner.

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0053] In order to be able to timely and reliably remind the user whether the air conditioner filter element needs to be replaced, the present application discloses a vehicle-mounted air conditioner detection method. This method uses two dust sensors arranged on both sides of the air conditioner filter element to detect the dust concentration in the air on both sides of the air duct. When the difference in the dust concentration detected by the two sensors is too low, it indicates that the air conditioner filter element cannot play a dust filtering role. At this time, the amount of dust on the air conditioner filter element is excessive and the user needs to replace the air conditioner filter element.

[0054] See Figure 1 , the vehicle-mounted air conditioner detection method disclosed in the embodiment of the present application may include:

[0055] Step S101: Obtain the detection value of the first dust sensor during the operation of the vehicle-mounted air conditioner, and the first dust sensor is arranged on the first side of the air conditioner filter element.

[0056] Step S102: Obtain the detection value of the second dust sensor during the operation of the vehicle-mounted air conditioner, and the second dust sensor is arranged on the second side of the air conditioner filter element.

[0057] In this solution, a first dust sensor and a second dust sensor are respectively arranged on both sides of the air conditioner filter element of the vehicle-mounted air conditioner. These two dust sensors are respectively used to detect the dust concentration values of the air on both sides of the air conditioner filter element; when the vehicle-mounted air conditioner is running, the first gray-scale sensor and the second gray-scale sensor are started.

[0058] In this solution, in order to ensure the reliability of the comparison result, the first gray-scale sensor and the second gray-scale sensor are gray-scale sensors of the same specification.

[0059] Step S103: Determine whether the difference between the detection values of the first dust sensor and the second dust sensor is less than a first preset value.

[0060] Normally, when the vehicle air conditioning system is in the external circulation mode, during the operation of the vehicle air conditioning system, air passes through the air filter element. The air filter element filters out dust in the air flow, thereby preventing dust in the external environment from entering the vehicle. At this time, the dust concentration on both sides of the air filter element will be significantly reduced. When excessive dust accumulates on the air filter element, the air filter element can no longer effectively filter dust. At this time, the reduction in dust concentration on both sides of the air filter element is not obvious, and the ventilation volume is significantly reduced. At this time, the difference between the dust concentration value detected by the first dust sensor and the dust concentration value detected by the second dust sensor is not large. At this time, it can be considered that a large amount of dust has accumulated on the air filter element, and the filter element needs to be replaced or cleaned in a timely manner. Therefore, in this step, it is necessary to judge the magnitude of the difference between the detection values of the first dust sensor and the second dust sensor. When the difference is less than the first preset value, it indicates that the air filter element can no longer effectively filter dust due to excessive dust accumulation. Among them, the magnitude of the first preset value can be set according to user requirements or design requirements. Different user requirements and design requirements may result in different magnitudes of the first preset value.

[0061] Step S104: When the difference is less than the first preset value, output an indication signal indicating that the air filter element needs to be replaced.

[0062] In this step, to facilitate reminding the user to replace the air filter element in a timely manner, when it is detected that the difference in the dust concentration detected by the dust sensors on both sides of the air filter element is less than the first preset value, an indication signal indicating that the air filter element needs to be replaced is output. Among them, this indication signal can be displayed through an indicator light on the dashboard or output through a voice module. Of course, this indication signal can be converted into a prompt message and sent to the user terminal bound to the vehicle. The user terminal can be a mobile phone or a specific application APP, etc.

[0063] As can be seen from the technical solutions disclosed in the above embodiments, in the above solutions, when the vehicle air conditioner is running, the first dust sensor and the second dust sensor arranged on both sides of the air filter element are used to detect the dust concentration on both sides of the air filter element, and it is judged whether the difference between the dust concentration values detected by the two sensors is less than the first preset value. When it is less than the first preset value, an indication signal indicating that the air filter element needs to be replaced is output, achieving the purpose of timely reminding the user whether the air filter element needs to be replaced.

[0064] In the technical solution disclosed in another embodiment of the present application, considering that if the dust concentration in the environment where the vehicle is located is extremely low, the difference between the detection values of the first dust sensor and the second dust sensor may be small under normal conditions, or even less than the first preset value. At this time, it may lead to the misoutput of the above-mentioned indication signal. Therefore, in order to ensure that the system can accurately output the above-mentioned indication signal, in the technical solution disclosed in the embodiment of the present application, an appropriate mapping relationship can also be selected based on the dust concentration value of the environment where the vehicle is located, and the mapping relationship is used to determine the first preset value adapted to the dust concentration value of the environment where the vehicle is located. Specifically, when the dust concentration value of the environment where the vehicle is located is smaller, the first preset value is smaller.

[0065] In this solution, the first side is the outside of the air-conditioning filter element, and the second side is the inside of the air-conditioning filter element. That is, the detection result of the first dust sensor is used to represent the dust concentration value of the environment where the vehicle is located. Of course, it can also be that the second side is the outside of the air-conditioning filter element and the first side is the inside of the air-conditioning filter element. Specifically, whether to use the first side or the second side of the air-conditioning filter element as the outside of the air-conditioning filter element can be freely selected. In this solution, taking the first side as the outside of the air-conditioning filter element and the second side as the inside of the air-conditioning filter element is only a specific example for introducing the solution. At this time, refer to Figure 2 , and determining whether the difference between the detection values of the first dust sensor and the second dust sensor is less than the first preset value includes:

[0066] Step S201: Obtain a first mapping relationship that matches the detection value of the first dust sensor;

[0067] Step S202: Obtain a first preset value that matches the detection value of the first dust sensor based on the first mapping relationship.

[0068] In this solution, when the dust concentration value of the environment where the vehicle is located is too low, the first preset value is set to be relatively low. When the difference between the detection values of the first dust sensor and the second dust sensor is less than the relatively low first preset value, it indicates that the air-conditioning filter element does not play a high filtering role. At this time, it is considered that the air-conditioning filter element needs to be replaced. When the dust concentration value of the environment where the vehicle is located is too high, the first preset value is set to be relatively high. Only when the difference between the detection values of the first dust sensor and the second dust sensor is less than the relatively high first preset value can it be considered that the air-conditioning filter element needs to be replaced.

[0069] In the above solution disclosed in another embodiment of the present application, in order to reduce the system energy consumption, the execution frequency of the vehicle air conditioner detection method can be set. When the vehicle environment is in a high-dust environment for a long time, the execution frequency of the above solution is high. When the vehicle environment is in a high-dust environment for a long time, the execution frequency of the above solution is low. That is, in the above solution, it may further include: obtaining the detection values of the first dust sensor in the most recent N times, calculating the average value of the detection values of the first dust sensor in the N times, obtaining the detection time interval adapted to the average value. When the vehicle air conditioner system is started, obtain the current system time and the execution time of the previous vehicle air conditioner detection method, and calculate whether the difference between the two times is greater than the detection time interval. When it is greater than the detection time interval, perform the action: obtain the detection value of the first dust sensor during the operation of the vehicle air conditioner and subsequent actions. When it is less than the detection time interval, do not perform the action this time: obtain the detection value of the first dust sensor during the operation of the vehicle air conditioner and subsequent actions. In this solution, by configuring the execution interval of the vehicle air conditioner detection method based on the dust concentration of the environment where the vehicle is located, it is not necessary to execute the above solution every time the vehicle air conditioner system is started, thereby reducing the system energy consumption. Moreover, it is not necessary to repeatedly remind the user to replace the air conditioner filter when the user does not want to replace it.

[0070] In the technical solution disclosed in another embodiment of the present application, when the dust concentration of the environment where the vehicle is located is too high and the air conditioner filter cannot effectively filter the dust in the air, in order to prevent external dust from entering the vehicle interior, the vehicle air conditioner can turn on the internal circulation mode. If the dust concentration of the environment where the vehicle is located is not too high, the vehicle air conditioner can turn on the external circulation mode. That is, see Figure 3 , when the difference is greater than the first preset value, the above method further includes:

[0071] Step S301: Determine whether the detection value of the first dust sensor is greater than the second preset value.

[0072] The second preset value is a dust concentration value. In this solution, when the difference is greater than the first preset value, in order not to increase the dust concentration inside the vehicle, it is necessary to determine whether the detection value of the first dust sensor is greater than the second preset value. If it is greater than the second preset value, it indicates that the dust concentration of the environment where the vehicle is located is relatively high. At this time, step S302 needs to be executed to control the vehicle air conditioner to switch to the air internal circulation mode to prevent external dust from entering the vehicle interior. When the dust concentration value of the environment where the vehicle is located is less than the second preset value, it indicates that the dust concentration value of the environment where the vehicle is located is normal. At this time, the vehicle air conditioner is switched to the air external circulation mode to provide better ventilation for the user.

[0073] Step S302: When the detection value of the first dust sensor is greater than the second preset value, switch the vehicle-mounted air conditioner to the air recirculation mode.

[0074] Step S303: When the detection value of the first dust sensor is less than the second preset value, switch the vehicle-mounted air conditioner to the air external circulation mode.

[0075] In the technical solution disclosed in another embodiment of the present application, considering that if the user uses the vehicle-mounted air conditioner too infrequently, for example, once a month, two months or longer, at this time, the user's demand for the vehicle-mounted air conditioner is relatively low, and the service life of the air filter element can be appropriately extended, that is, the filtering performance of the air filter element can be appropriately relaxed. That is, in the above method, when the difference is less than the first preset value, an indication signal for characterizing that the air filter element needs to be replaced is output. Specifically, it may include: when the difference is less than the first preset value, obtain the frequency value of the user using the vehicle-mounted air conditioner; when the frequency value of the user using the vehicle-mounted air conditioner is less than the preset frequency; determine whether the difference is less than the third preset value; when the difference is less than the third preset value, output an indication signal for characterizing that the air filter element needs to be replaced. In this embodiment, when it is detected that the difference is less than the first preset value and the frequency of the user using the vehicle-mounted air conditioner is less than the preset frequency value, it indicates that the user's demand for the vehicle-mounted air conditioner is relatively low. At this time, it is necessary to continue to determine whether the difference is less than the third preset value. If it is less, it indicates that the air filter element needs to be replaced, otherwise it indicates that the air filter element does not need to be replaced. Among them, the third preset value is less than the first preset value. By reasonably setting the third preset value, the replacement standard for the air filter element can be appropriately relaxed.

[0076] In the technical solution disclosed in another embodiment of the present application, considering cold weather and when the difference is less than the third preset value, at this time, it indicates that the dust amount on the air filter element has accumulated excessively, and it is difficult for the vehicle-mounted air conditioner to achieve good heating. At this time, the vehicle's warm air can be used for heating. That is, if it is detected that the difference is less than the third preset value, determine whether the vehicle-mounted air conditioner mode is the heating mode. When it is the heating mode, control the vehicle's warm air to turn on.
