[0002] With the rapid development of automotive intelligence, intelligent windshield wipers are becoming increasingly common. These intelligent car features automatically adjust their operating mode based on rainfall intensity or vehicle speed, providing drivers with clear visibility and improving safety and comfort in rainy weather. However, in the cold winters of northern regions, if a vehicle is equipped with intelligent wipers, they may misidentify and activate incorrectly when encountering snow, frost, or other obstructions on the windshield. This not only affects the lifespan of the wipers but also creates a negative user experience. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the first objective of this invention is to provide a windshield wiper control method that acquires outdoor ambient temperature and vehicle speed information. When the outdoor ambient temperature is lower than a preset temperature threshold and the vehicle speed is lower than a preset vehicle speed threshold, the surface condition of the windshield is acquired. If a preset obstacle is determined based on the surface condition of the windshield, the windshield wipers are controlled to enter a protection mode. This avoids false recognition and incorrect activation of the wipers, improves the user experience, protects the wipers in cold winter conditions, extends the lifespan of the wipers, and reduces the frequency of wiper maintenance.

[0008] According to the windshield wiper control method of the present invention, outdoor ambient temperature and vehicle speed information are acquired. When the outdoor ambient temperature is lower than a preset temperature threshold and the vehicle speed is lower than a preset vehicle speed threshold, the surface state of the windshield is acquired. If a preset obstacle is determined based on the surface state of the windshield, the windshield wipers are controlled to enter a protection mode. Therefore, this method can avoid wiper misidentification and erroneous activation, improve the user experience, protect the wipers in cold winter conditions, extend the wiper's lifespan, and reduce the frequency of wiper maintenance.

[0027] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] The following description, with reference to the accompanying drawings, outlines an embodiment of the windshield wiper control method, a computer-readable storage medium, a vehicle, and a windshield wiper control device.

[0029] Figure 1 This is a flowchart of a windshield wiper control method according to an embodiment of the present invention.

[0030] like Figure 1 As shown, the windshield wiper control method of this embodiment may include the following steps:

[0031] S1, obtains outdoor ambient temperature and vehicle speed information.

[0032] S2: When the outdoor ambient temperature is lower than a preset temperature threshold and the vehicle speed is lower than a preset vehicle speed threshold, obtain the surface condition of the windshield. The preset temperature threshold and preset vehicle speed threshold can be determined according to the actual situation.

[0033] S3: If a preset obstacle is detected based on the surface condition of the windshield, the wipers are controlled to enter protection mode. The preset obstacle can be determined according to the actual situation.

[0034] Specifically, the intelligent windshield wiper winter protection function is a control method for intelligent windshield wipers in automatic mode during cold winter scenarios. Its main goal is to improve user experience and avoid the annoyance of wipers freezing and malfunctioning in winter. Firstly, it acquires outdoor ambient temperature and vehicle speed information to determine if conditions warrant the winter protection mode. For example, the vehicle's sensor system (such as temperature and speed sensors) can obtain real-time outdoor ambient temperature and the vehicle's current speed. For instance, a temperature sensor installed on the exterior of the vehicle can accurately measure the outside air temperature, while a speed sensor determines vehicle speed by measuring the rotational speed of the wheels.

[0035] When outdoor ambient temperature and vehicle speed information is obtained, this information can be analyzed to determine whether the windshield wiper winter protection mode needs to be activated. This prevents the wipers from erroneously activating under low temperature and low speed conditions (which may indicate the vehicle is stopped or moving slowly). For example, if the preset temperature threshold is -10℃ and the preset vehicle speed threshold is 7km / h, and the detected outdoor ambient temperature is lower than the preset temperature threshold (-10℃) and the vehicle speed is lower than the preset vehicle speed threshold (7km / h), it indicates that the current outdoor ambient temperature is low, and the vehicle is not running or is moving slowly. In this case, due to the low outdoor ambient temperature, there may be snow or frost on the windshield. To prevent the wipers from erroneously activating, the surface condition of the windshield can be assessed. For example, this can be done using infrared sensors, cameras, or other types of sensors that can identify whether there is snow, ice, or other obstacles on the windshield.

[0036] It should be noted that in cold weather, even if the outdoor temperature is below the preset temperature threshold, if the vehicle is traveling at high speed, the ice and snow on the windshield may have already been cleared by the wind or by human force. In this case, it may be appropriate to turn on the windshield wipers. Therefore, it is necessary to ensure that the vehicle speed is below the preset speed threshold.

[0037] Therefore, when a preset obstacle is detected based on the surface condition of the windshield, the wipers can be controlled to enter a protection mode. For example, the preset obstacles might be snow and ice. If snow or ice is detected on the windshield surface, the wipers will enter protection mode to protect them from damage and prevent their use under unsuitable conditions. For instance, in this protection mode, the wipers will not activate until the obstacle is cleared or environmental conditions change. This avoids wiper misidentification and erroneous activation, improves the user experience, protects the wipers in cold winter conditions, extends their lifespan, and reduces the frequency of wiper maintenance.

[0038] According to one embodiment of the present invention, controlling the windshield wipers to enter a protection mode includes: controlling the windshield wipers to enter a manual control wiping mode.

[0039] Specifically, when controlling the windshield wipers to enter protection mode, it can be switched to manual wiping mode. This ensures that the wipers will not automatically activate under certain environmental conditions, such as low temperatures or icy weather, thereby avoiding potential damage or unnecessary use.

[0040] For example, in cold winters, especially when temperatures are below freezing, the rubber blades of windshield wipers may harden due to the low temperature or freeze to the windshield due to snow or ice. Automatic wiper activation can cause the following problems: damage to the wipers, as frozen wipers may tear or break upon activation; and impaired driving safety, as frozen wipers can obstruct the driver's view and increase the risk of accidents. Therefore, in manual wiper mode, the driver can manually activate the wipers as needed. This allows the driver to operate the wipers only after confirming that the ice and snow on the windshield have been cleared and that the wipers are safe to use. This avoids the wipers automatically activating when they detect rainfall or changes in humidity. Additionally, the vehicle's instrument panel or center console display can show that the wipers are currently in manual mode, or an audible alert can be given to inform the driver that the wipers are in manual mode.

[0041] According to one embodiment of the present invention, after the windshield wiper enters the protection mode, the windshield wiper control method further includes: controlling the heating device corresponding to the windshield to turn on.

[0042] Specifically, once the windshield wipers are confirmed to be in protection mode, it indicates the presence of snow, frost, or other obstructions on the windshield. In this case, the corresponding heating device on the windshield can be activated. For example, this heating device could be a defroster. By activating the heating device, the windshield can be heated to quickly melt the snow or ice, thus clearing the obstructions and ensuring the driver has a clear view, improving driving safety.

[0043] Additionally, the heating device can be connected to a temperature sensor to monitor the glass temperature and adjust the heating intensity to prevent the windshield from overheating. The operating status of the windshield heating device can also be displayed on the vehicle's instrument panel or central control screen.

[0044] According to one embodiment of the present invention, the windshield wiper control method further includes: controlling the windshield wiper to exit the protection mode when the vehicle speed information is greater than or equal to a preset vehicle speed threshold.

[0045] Specifically, vehicle speed information is a key factor in determining whether the vehicle is moving and whether the driving conditions are suitable for using the windshield wipers. For example, if the preset speed threshold is 7 km / h, and the vehicle speed information is greater than or equal to the preset speed threshold (7 km / h), it indicates that the current vehicle speed is relatively high, and the vehicle is considered to be driving normally (the driver will only accelerate normally when obstacles are cleared). In this case, the windshield wipers may need to intervene, thus allowing the wipers to exit the protection mode.

[0046] According to one embodiment of the present invention, after controlling the windshield wiper to exit the protection mode, the windshield wiper control method further includes: controlling the windshield wiper to enter the automatic control wiping mode.

[0047] Furthermore, according to an embodiment of the present invention, when the windshield wipers are operating in an automatic control wiping mode, the windshield wiper control method further includes: controlling the wiping frequency of the windshield wipers based on data detected by a rain sensor.

[0048] Specifically, after controlling the windshield wipers to exit the protection mode, it is also possible to control them to enter the automatic wiping mode. In automatic wiping mode, the wiper frequency is automatically adjusted according to changes in rainfall or vehicle speed to ensure the windshield remains clear at all times, thereby reducing driver visual interference and improving driving safety in rainy or snowy weather. Furthermore, the automatic control method reduces the need for the driver to manually adjust the wiper frequency, providing a more comfortable driving experience.

[0049] For example, the wiping frequency of the windshield wipers can be controlled by data detected by a rain sensor. In heavy rainfall, the wiping frequency can be increased, while in light rainfall, it can be decreased. This real-time automatic adjustment of the wiper frequency ensures optimal wiper performance and improves driver safety. The rain sensor can be integrated into the windshield or near the rearview mirror, sensing raindrops on the windshield and adjusting the wiper speed based on their size and density. This adapts to different driving conditions, automatically adjusting the wiper's operation to protect it from damage in inclement weather while ensuring good visibility when needed, thus enhancing driving safety and comfort.

[0050] According to one embodiment of the present invention, the windshield wiper control method further includes: maintaining the windshield wiper control mode unchanged when it is determined from the surface condition of the windshield that there is no preset obstacle.

[0051] Specifically, the system assesses the surface condition of the windshield. If the surface condition determines that there are no pre-defined obstacles, the wiper control mode remains unchanged. In other words, if the windshield surface is in good condition, without snow, ice, or other obstructions, the system will not enter protective mode even in low temperatures and at low vehicle speeds. Maintaining the current wiper control mode ensures that the wipers continue to operate at an appropriate speed and in the appropriate manner to adapt to current weather conditions. Furthermore, frequent switching of wiper modes can lead to unnecessary wear or driver inconvenience; maintaining the same wiper control mode reduces these problems.

[0052] The following is combined Figure 2The control method of the present invention will be described below.

[0053] As a specific example, the windshield wiper control method of the present invention may include the following steps:

[0054] S101, obtains outdoor ambient temperature and vehicle speed information.

[0055] S102, determine whether the outdoor ambient temperature is lower than a preset temperature threshold and whether the vehicle speed is lower than a preset vehicle speed threshold. If yes, proceed to step S103; if no, proceed to step S108.

[0056] S103, Obtain the surface condition of the windshield.

[0057] S104. Determine whether there is a preset obstacle based on the surface condition of the windshield. If yes, proceed to step S105; otherwise, proceed to step S109.

[0058] S105 controls the windshield wipers to enter manual wiping mode and controls the corresponding heating device on the windshield to start operating.

[0059] S106. Check if the vehicle speed information is greater than or equal to the preset vehicle speed threshold. If yes, proceed to step S107; if no, proceed to step S105.

[0060] S107 controls the wiper to exit protection mode.

[0061] S108 controls the windshield wipers to enter automatic wiping mode.

[0062] S109, keep the wiper control mode unchanged.

[0063] In summary, the windshield wiper control method according to embodiments of the present invention acquires outdoor ambient temperature and vehicle speed information. When the outdoor ambient temperature is lower than a preset temperature threshold and the vehicle speed is lower than a preset vehicle speed threshold, the surface state of the windshield is acquired. If a preset obstacle is determined based on the surface state of the windshield, the windshield wipers are controlled to enter a protection mode. Therefore, this method can avoid wiper misidentification and erroneous activation, improve the user experience, protect the wipers in cold winter conditions, extend the wiper's lifespan, and reduce the frequency of wiper maintenance.
