[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The front cabin of the vehicle is equipped with a fan, which has a heat dissipation function. When the vehicle is driving in harsh environments such as deserts, muddy ground or sandstorms, the fan is easily contaminated. For example, sand, mud or gravel enters the fan, causing the fan to be contaminated, affecting the normal operation of the fan, and even causing the fan to fail.

[0021] The embodiment of the present invention provides a method for controlling a fan. Figure 1 As shown, the method includes:

[0022] Step 101, controlling the fan to change state to operate for self-cleaning.

[0023] The controller can control the fan to operate in variable states for self-cleaning.

[0024] In summary, the embodiment of the present invention provides a method for controlling a fan, in which a controller can control the fan to operate in a variable state to perform self-cleaning, thereby avoiding the problem that the fan is affected in normal operation or even fails due to contamination.

[0025] Figure 2 is a flow chart of another fan control method provided by an embodiment of the present invention. Figure 2 As shown, the method may include:

[0026] Step 201: Obtain at least one of the vehicle's environmental information and mode status information.

[0027] The controller may obtain at least one of the environmental information and mode status information of the vehicle. The environmental information may include at least one of the location information and weather information of the vehicle, the location information may be the current location information, and the weather information may be the current weather information. The location information may be the longitude and latitude, and the weather information may be a parameter used to reflect the weather of the vehicle's current environment, for example, the weather information may include parameters such as temperature, visibility, and wind speed. The mode status information may be a parameter used to indicate the current operating mode of the vehicle, for example, when the mode status information is 0, it indicates that the current operating mode of the vehicle is the sand operating mode.

[0028] The vehicle may be provided with a positioning system, and the controller may obtain the location information of the vehicle through the positioning system. The controller may send the location information of the vehicle to the weather platform, so that the weather platform returns the weather information at the location information to the controller.

[0029] Step 202: Identify whether the fan is contaminated according to at least one of the environmental information and the mode status information.

[0030] After acquiring at least one of the environmental information and the mode status information of the vehicle, the controller can identify whether the fan is contaminated according to at least one of the environmental information and the mode status information. In the case where it is identified that the fan is contaminated according to at least one of the environmental information and the mode status information, the controller can determine that the fan needs to be cleaned, and thus executes step 205. In the case where it is identified that the fan is not contaminated according to the environmental information and that the fan is not contaminated according to the mode status information, the controller can determine that the fan does not need to be cleaned, and thus ends the process.

[0031] If the environmental information includes location information, the controller can determine the area where the vehicle is located based on the location information. When it is determined that the vehicle is in the target area based on the location information, it can be determined that the fan is contaminated. When it is determined that the vehicle is not in the target area based on the location information, it can be determined that the fan is not contaminated.

[0032] The target area is used to characterize the environment where the fan is susceptible to pollution. Optionally, the target area may include a desert area or a muddy road area.

[0033] It is understandable that when the vehicle is driving in the target area, sand or mud may stick to the fan's motor, hub, blades, etc., causing the fan to be contaminated and affecting the normal operation of the fan, which may cause the fan's dynamic balance to deteriorate or even fail.

[0034] If the environmental information includes weather information, the controller can determine whether the weather of the vehicle's current environment is the target weather according to the weather information. If it is determined that the weather of the vehicle's current environment is the target weather according to the weather information, it can be determined that the fan is polluted. If it is determined that the weather of the vehicle's current environment is not the target weather according to the weather information, it can be determined that the fan is not polluted.

[0035] The target weather refers to weather that is likely to cause pollution to the fan, and the target weather may include sandstorm weather.

[0036] It is understandable that when the weather in the vehicle's current environment is the target weather, sand or mud may stick to the fan's motor, hub, blades, etc., causing the fan to be contaminated and affecting the normal operation of the fan, which may cause the fan's dynamic balance to deteriorate or even fail.

[0037] The controller may determine that the fan is contaminated when the vehicle is determined to be running in the target mode according to the mode status information, or may determine that the fan is not contaminated when the vehicle is determined not to be running in the target mode according to the mode status information.

[0038] The target mode refers to an operation mode that is likely to cause pollution to the fan. The target mode may include a sand operation mode or a mud operation mode. The sand operation mode may also be called a desert mode or a wasteland mode.

[0039] It is understandable that when the vehicle is driving on sand or mud, the vehicle will operate in target mode. When the vehicle is operating in target mode, sand or mud may adhere to the motor, hub, blades, etc. of the fan, causing the fan to be contaminated, affecting the normal operation of the fan, and further causing the dynamic balance of the fan to deteriorate or even fail.

[0040] Step 203: Obtain vibration information of the fan.

[0041] In the embodiment of the present invention, the controller may obtain vibration information of the fan, wherein the vibration information includes the vibration frequency of the fan.

[0042] Optionally, a fan vibration monitoring component may be provided in the vehicle, which is used to monitor the vibration information of the fan in real time when the vehicle is in a driving state or a parked state, and send the monitored vibration information to the controller, so that the controller can obtain the vibration information of the fan.

[0043] Step 204: Determine whether the fan is abnormal based on the vibration information.

[0044] After the controller obtains the vibration information of the fan, it can determine whether the fan is abnormal according to the vibration information. If it is determined that the fan is abnormal according to the vibration information, it can be identified that the fan is contaminated, so step 205 is executed. If it is determined that the fan is not abnormal according to the vibration information, it can be identified that the fan is not contaminated, so the process ends.

[0045] The controller can determine that the fan is abnormal if the vibration frequency of the fan exceeds the preset fan vibration threshold according to the vibration information. If the vibration frequency of the fan does not exceed the preset fan vibration threshold according to the vibration information, it can be determined that the fan is not abnormal.

[0046] The fan vibration threshold may be pre-stored in the controller, and the fan vibration threshold may be a fan vibration threshold of the fan in a daily cooling condition.

[0047] It is understandable that when sand or dirt is stuck to the motor, hub, blades, etc. of the fan, the vibration frequency of the fan will exceed the preset fan vibration threshold, which may cause the dynamic balance of the fan to deteriorate or even fail.

[0048] In an optional implementation of an embodiment of the present invention, when the controller determines that the fan is abnormal based on the vibration information, it can determine that the fan is contaminated, and therefore issues a fan self-cleaning prompt message, thereby prompting the user to check the fan in time and determine whether to control the fan to self-clean.

[0049] The fan self-cleaning prompt information may be a text message or a voice message, etc. If the fan self-cleaning prompt information is a text message, the controller may send the fan self-cleaning prompt information in a pop-up window.

[0050] Optionally, if the method is used for a vehicle, the controller may control the vehicle to issue a fan self-cleaning prompt message.

[0051] In another optional implementation of the embodiment of the present invention, when the controller determines that the fan is abnormal according to the vibration information, the controller may directly execute step 205 .

[0052] In an embodiment of the present invention, the controller may use the above steps 201 and 202 to identify whether the fan is contaminated, and if it is identified that the fan is contaminated, execute step 205. The above steps 203 and 204 may also be used to identify whether the fan is contaminated, and if it is identified that the fan is contaminated, execute step 205.

[0053] Step 205: Determine whether the vehicle meets the pollution removal conditions.

[0054] When the controller identifies that the fan is contaminated, it can determine whether the vehicle meets the contamination removal condition. If it is determined that the vehicle meets the contamination removal condition, step 206 can be executed. If it is determined that the vehicle does not meet the contamination removal condition, the process ends.

[0055] As an optional implementation, the controller may determine that the vehicle meets the pollution removal condition when the controller detects that the vehicle is in the target state. When the controller detects that the vehicle is not in the target state, the controller may determine that the vehicle does not meet the pollution removal condition. The target state may include an OFF gear state, a low voltage state of the vehicle, or a power-off state of the vehicle.

[0056] For example, for pure electric vehicles or hybrid vehicles, the vehicle is in a high voltage state when driving, and the fan may be working at this time. In this case, it is not convenient to self-clean the fan. For fuel vehicles, when the vehicle is in the OFF gear state or the vehicle is parked, the fan can be self-cleaned at this time.

[0057] As another optional implementation, the controller may determine that the vehicle meets the pollution removal condition when it detects that the vehicle is in the target state and the vehicle is in a preset safety area. The controller may determine that the vehicle does not meet the pollution removal condition when it detects that the vehicle is not in the target state and / or the vehicle is not in a preset safety area.

[0058] The position of the safety zone may be pre-stored in the controller, and the controller may determine whether the vehicle is in the safety zone according to the position information of the vehicle. The target state may include an OFF gear state, a low voltage state of the vehicle, or a power-off state of the vehicle.

[0059] As another optional implementation, the controller may determine that the vehicle meets the pollution removal condition when it detects that the vehicle is in the target state, the vehicle is in a preset safety area, and the vehicle is in a flat state. When the controller detects the target condition, it may determine that the vehicle does not meet the pollution removal condition. The target condition may include at least one of: the vehicle is not in the target state, the vehicle is not in a preset safety area, and the vehicle is not in a flat state. The target state may include an OFF gear state, a low voltage state of the whole vehicle, or a power-off state of the whole vehicle.

[0060] It should be noted that the manner of determining whether the vehicle meets the pollution-clearing condition is not limited to the above-mentioned implementation manner. For example, the controller may also determine that the vehicle meets the pollution-clearing condition when the fan is not working.

[0061] Step 206: Control the fan to change state to run for self-cleaning.

[0062] When the controller identifies that the fan is contaminated, if it determines that the vehicle meets the pollution cleaning conditions, it can control the fan to change state to operate for self-cleaning, so that the fan enters the pollution cleaning mode.

[0063] In an optional implementation of the embodiment of the present invention, after the controller recognizes that the fan is contaminated by the above steps 201 and 202, if it is determined that the vehicle meets the pollution cleaning conditions, the controller can control the fan to change state to perform self-cleaning.

[0064] Optionally, the controller may execute a post-cooling program, and after the post-cooling program is completed, control the fan to change state to operate.

[0065] In another optional implementation of the embodiment of the present invention, after the controller recognizes that the fan is contaminated by using the above steps 203 to 204, after issuing a fan self-cleaning prompt message and generating a user cleaning instruction based on the fan self-cleaning prompt message, if it is determined that the vehicle meets the cleaning conditions, the controller can respond to the user cleaning instruction and control the fan to change state operation for self-cleaning.

[0066] The user cleaning instruction is generated based on the fan self-cleaning prompt information. After receiving a confirmation operation for the fan self-cleaning prompt information, the controller can determine that the user cleaning instruction is received.

[0067] In another optional implementation of the embodiment of the present invention, the controller recognizes that the fan is contaminated by adopting the above steps 203 to 204. If it is determined that the vehicle meets the pollution cleaning conditions, the fan can be controlled to change state to operate for self-cleaning.

[0068] In the embodiment of the present invention, the controller may control the fan to operate in a target mode, wherein the target mode may include at least one of an intermittent operation mode, a variable speed operation mode, and a variable direction operation mode.

[0069] When the target mode includes an intermittent operation mode, the controller may control the fan to run forward at the target speed for a first preset time, and then control the fan to stop for a second preset time, and repeat this process at least once.

[0070] Alternatively, the controller may control the fan to reversely run at the target speed for a first preset time, and then control the fan to stop for a second preset time, and repeat this process at least once. The first preset time and the second preset time may be pre-stored in the controller.

The first speed and the second speed may be pre-stored in the controller.

[0074] Alternatively, the controller can control the fan to reversely run at a first speed for a first preset time, and then control the fan to stop for a second preset time, and then control the fan to reversely run at a second speed for a third preset time, and then control the fan to stop for a fourth preset time, and repeat this process at least once, wherein the first speed is different from the second speed.

[0075] Alternatively, the controller can control the fan to run forward at a first variable speed for a first preset time, then control the fan to stop for a second preset time, then control the fan to run forward at a second variable speed for a third preset time, and then control the fan to stop for a fourth preset time, and repeat this process at least once.

[0076] Alternatively, the controller can control the fan to reversely run at a first changed speed for a first preset time, then control the fan to stop for a second preset time, then control the fan to reversely run at a second changed speed for a third preset time, and then control the fan to stop for a fourth preset time, and repeat this at least once.

[0077] When the target mode includes an intermittent operation mode, a variable speed operation mode and a variable direction operation mode, the controller can control the fan to run forward at a first speed for a first preset time, and then control the fan to stop for a second preset time, and then control the fan to run reversely at a second speed for a third preset time, and then control the fan to stop for a fourth preset time, and repeat this process at least once, wherein the first speed is different from the second speed.

[0078] Alternatively, the controller can control the fan to run in reverse at a first speed for a first preset time, and then control the fan to stop for a second preset time, and then control the fan to run forward at a second speed for a third preset time, and then control the fan to stop for a fourth preset time, and repeat this process at least once, wherein the first speed is different from the second speed.

[0079] Alternatively, the controller can control the fan to run forward at a first variable speed for a first preset time, then control the fan to stop for a second preset time, then control the fan to run reversely at a second variable speed for a third preset time, and then control the fan to stop for a fourth preset time, and repeat this process at least once.

[0080] Alternatively, the controller can control the fan to run in reverse at a first variable speed for a first preset time, then control the fan to stop for a second preset time, then control the fan to run forward at a second variable speed for a third preset time, and then control the fan to stop for a fourth preset time, and repeat this process at least once.

[0081] When the target mode includes a variable speed operation mode and a variable direction operation mode, the controller can control the fan to run forward at a first speed for a first preset time, and then control the fan to run reversely at a second speed for a third preset time, and repeat this at least once, wherein the first speed is different from the second speed.

[0082] Alternatively, the controller may control the fan to run in reverse at a first speed for a first preset time, and then control the fan to run forward at a second speed for a third preset time, and repeat this process at least once, wherein the first speed is different from the second speed.

[0083] Alternatively, the controller may control the fan to rotate forward at a first variable speed for a first preset time, and then control the fan to rotate reversely at a second variable speed for a third preset time, and repeat this process at least once.

[0084] Alternatively, the controller may control the fan to run in reverse at a first variable speed for a first preset time, and then control the fan to run in forward at a second variable speed for a third preset time, and repeat this process at least once.

[0085] When the target mode includes a variable speed operation mode, the controller can control the fan to run forward at a first speed for a first preset time, and then control the fan to run forward at a second speed for a third preset time, and repeat this at least once, wherein the first speed is different from the second speed.

[0086] Alternatively, the controller may control the fan to reversely run at a first speed for a first preset time, and then control the fan to reversely run at a second speed for a third preset time, and repeat this process at least once, wherein the first speed is different from the second speed.

[0087] Alternatively, the controller may control the fan to rotate forward at a first variable speed for a first preset time, and then control the fan to rotate forward at a second variable speed for a third preset time, and repeat this process at least once.

[0088] Alternatively, the controller may control the fan to reversely run at a first variable speed for a first preset time, and then control the fan to reversely run at a second variable speed for a third preset time, and repeat this process at least once.

[0089] When the target mode includes a variable direction operation mode, the controller may control the fan to run forward at the target speed for a first preset time, and then control the fan to run reversely at the target speed for a second preset time, and repeat this process at least once.

[0090] Alternatively, the controller may control the fan to run in reverse at the target speed for a first preset time, and then control the fan to run forward at the target speed for a second preset time, and repeat this process at least once.

[0091] Step 207: During the self-cleaning process of the fan, control the fan to stop self-cleaning.

[0092] During the self-cleaning process of the fan, the controller can control the fan to stop self-cleaning, thereby causing the fan to exit the cleaning mode.

[0093] In an optional implementation, the controller may control the fan to stop self-cleaning in response to a user instruction during the self-cleaning process of the fan, wherein the user instruction includes a power-on instruction or a self-cleaning termination instruction.

[0094] Optionally, a self-cleaning termination button may be provided in the vehicle, and after receiving a selection operation of the user on the self-cleaning termination button, the vehicle may generate a self-cleaning termination instruction.

[0095] In another optional implementation, the controller may obtain vibration information of the fan during the self-cleaning process of the fan, and when it is determined according to the vibration information that the vibration frequency of the fan is greater than a preset abnormal frequency threshold, the fan may be controlled to stop self-cleaning. When it is determined according to the vibration information that the vibration frequency of the fan is less than or equal to a preset abnormal frequency threshold, the fan may be controlled to maintain the self-cleaning state unchanged. The abnormal frequency threshold may be pre-stored in the controller.

[0096] When the controller determines that the vibration frequency of the fan is greater than the preset abnormal frequency threshold based on the vibration information, the user needs to check the fan after shutting down and powering off the machine while ensuring the safety of the vehicle and personnel to see if there are other reasons causing the fan abnormality.

[0097] In the embodiment of the present invention, when the controller identifies that the cooling fan is contaminated, if it determines that the vehicle meets the cleaning conditions, it can control the cooling fan to run for self-cleaning. This can avoid the problem that the cooling fan is affected by contamination and the cooling fan's normal operation is affected, which in turn causes the cooling fan's dynamic balance to deteriorate or even fail.

[0098] In summary, the embodiment of the present invention provides a method for controlling a fan, in which a controller can control the fan to operate in a variable state to perform self-cleaning, thereby avoiding the problem that the fan is affected in normal operation or even fails due to contamination.

[0099] It should be noted that in the process of implementing the fan control method, the above step 205 can be deleted, that is, when the controller recognizes that the fan is contaminated, it can control the fan to change state to operate for self-cleaning.

[0100] In addition, the fan control method provided in the embodiment of the present invention can be applied to vehicles, and can also be applied to other target devices equipped with fans, for example, the target device can be a computer device, a medical device, a purifier, etc.

[0101] When the fan control method is used for a target device, the controller may identify whether the fan is contaminated by executing the above steps 203 and 204 .
