[0022] Before providing a detailed description of the embodiments of this application, some of the nouns and terms used in the embodiments of this application will be explained first. The nouns and terms used in the embodiments of this application shall be interpreted as follows: A car rain sensor is an electronic device used in automobiles to control windshield wipers using infrared sensing. It works primarily based on infrared optical principles and uses a sensing system consisting of an emitting diode and a receiving diode to monitor the amount of rain on the windshield in real time.

[0023] In automotive technology, the cleanliness of windshield wipers during water removal significantly impacts driving safety. Worn wipers can leave a significant amount of residual water on the windshield after wiping, affecting driver safety. Therefore, timely replacement of wipers effectively improves driving safety. However, current technology relies entirely on the owner's experience to determine the need for replacement. Owners unfamiliar with their vehicles cannot readily assess the aging of the wipers or their wiping performance, hindering timely replacement or cleaning.

[0024] In view of this, this application provides a method and related equipment for handling abnormal windshield wipers, enabling vehicle owners to promptly replace or clean the wipers, effectively improving vehicle driving safety.

[0025] The vehicle windshield wiper malfunction handling method provided in this application relates to the field of vehicle technology. This method can be applied to a terminal, a server, or software running on either a terminal or a server. In some embodiments, the terminal can be a smartphone, tablet, laptop, desktop computer, smart speaker, smartwatch, or in-vehicle terminal, but is not limited to these. The server can be configured as an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms. The server can also be a node server in a blockchain network. The software can be an application implementing the vehicle windshield wiper malfunction handling method, but is not limited to the above forms.

[0026] This application can be used in a wide variety of general-purpose or special-purpose computer system environments or configurations. Examples include: personal computers, server computers, handheld or portable devices, tablet devices, multiprocessor systems, microprocessor-based systems, programmable consumer electronics, network PCs, minicomputers, mainframe computers, and distributed computing environments including any of the above systems or devices. This application can be described in the general context of computer-executable instructions executed by a computer, such as program modules. Generally, program modules include routines, programs, objects, components, data structures, etc., that perform specific tasks or implement specific abstract data types. This application can also be practiced in distributed computing environments where tasks are performed by remote processing devices connected via a communication network. In distributed computing environments, program modules can reside in local and remote computer storage media, including storage devices.

[0027] It should be noted that in all specific embodiments of this application, when processing data related to user identity or characteristics, such as user information, user behavior data, user historical data, and user location information, user permission or consent is obtained first. Furthermore, the collection, use, and processing of this data comply with relevant laws, regulations, and standards. In addition, when embodiments of this application require access to sensitive personal information of users, separate permission or consent from the user is obtained through pop-ups or redirection to confirmation pages. Only after obtaining the user's separate permission or consent is the necessary user-related data required for the proper functioning of these embodiments acquired.

[0028] The embodiments of this application will be described in detail below with reference to the accompanying drawings: Reference Figure 1The vehicle to which the method of this application embodiment is applied is pre-equipped with a rain sensor 110, an image generation component, and an anomaly warning component 130. The rain sensor detects real-time rainfall data on the windshield, specifically detecting residual rainfall data on the windshield after wiper operation. The image generation component acquires a surface image of the windshield, specifically acquiring a surface image of the windshield after wiper operation. The anomaly warning component provides an anomaly warning when an anomaly occurs in the vehicle, specifically providing an aging warning or cleaning warning when the wipers show signs of aging or are dirty.

[0029] It is understandable that, such as Figure 1 As shown, the rain sensor 110 is disposed in a first preset area of ​​the windshield. This first preset area can be the mounting position of the vehicle's interior rearview mirror, in order to better detect the surface rainfall of the windshield and improve the accuracy of subsequent analysis. Specifically, the rain sensor can detect the rainfall data on the vehicle's windshield through photoelectric effect, thereby reducing the influence of the external environment and improving the accuracy of detection. The image generation component includes a first camera 121 and a second camera 122. The first camera 121 is disposed at the first end of the back of the vehicle's interior rearview mirror, and the second camera 122 is disposed at the second end of the back of the vehicle's interior rearview mirror. The two cameras work together to acquire surface images of the windshield, and the surface rainfall data of the windshield can be obtained by analyzing the surface images acquired by the two cameras, thereby indirectly reflecting the performance status of the windshield wipers. The abnormality warning component 130 is disposed in a second preset area inside the vehicle. This second preset area can be the area in front of the driver during driving, such as the left side of the instrument panel, so that the driver can observe the warning information in a timely manner.

[0030] based on Figure 1 The installation diagram shown is as follows: Figure 2 As shown, this application embodiment provides a method for handling vehicle windshield wiper malfunctions, which may include, but is not limited to, steps S210 to S240: Step S210: After the windshield wipers in the vehicle are activated, acquire the real-time rainfall data collected by the rain sensor. The real-time rainfall data includes the rainfall data after the windshield wipers on the vehicle's windshield have performed the wiping operation. Step S220: Obtain the surface image captured by the image generation component, wherein the surface image includes the image of the windshield wipers on the vehicle after the wipers have performed the wiping operation; Step S230: Analyze the performance status of the wipers based on real-time rainfall data, or based on surface images, or based on real-time rainfall data and surface images, wherein the performance status includes the degree of aging or the cleanliness of the wiper surface. Step S240: Control the abnormal prompt status of the abnormal prompt component based on the performance status analysis results.

[0031] It is understood that in this embodiment, after determining that the windshield wipers are activated, the rain sensor or image generation component automatically enters the working state. Specifically, the rain sensor detects real-time rainfall data on the windshield after the wipers are activated, and the image generation component acquires a surface image of the windshield after the wipers are activated. Specifically, after acquiring the real-time rainfall data on the windshield after the wipers have activated, this embodiment can analyze the performance status of the wipers based on the real-time rainfall data. In this embodiment, the relationship between the real-time rainfall data and the residual rainfall threshold can be determined after obtaining the residual rainfall threshold. If the real-time rainfall data is less than the residual rainfall threshold, it indicates that the rainwater on the windshield has been almost completely wiped away after the wipers operated, therefore the wipers are in good working order and no replacement is needed. If the real-time rainfall data is greater than or equal to the residual rainfall threshold, it indicates that a significant amount of rainwater remains on the windshield after the wipers operated, meaning the wipers may be worn out or require cleaning. The driver should promptly operate the wipers to improve safety when driving in rainy weather. For example, as... Figure 3 As shown, when a vehicle is driven in rainy weather, after the windshield wipers are automatically turned on or manually activated by the driver, the rain sensor automatically enters working mode and collects real-time rainfall data on the windshield surface after the wipers have wiped. This real-time rainfall data is then compared to a preset residual rainfall threshold. If the real-time rainfall data does not reach the residual rainfall threshold, the rain sensor returns to its original state to continue collecting data. If the real-time rainfall data reaches the residual rainfall threshold, it indicates that the wipers may be worn out or require cleaning. The system then activates an alert component to provide a timely warning, allowing the driver to replace or clean the wipers promptly, effectively improving driving safety.

[0032] It is understood that this embodiment, after acquiring a surface image of the windshield after the wipers have performed a wiping operation, can analyze the performance status of the wipers based on the surface image. In this embodiment, the performance status of the wipers can be analyzed based on the residual rainwater traces on the windshield after analyzing the surface image. Specifically, this embodiment can analyze the residual rainwater density based on the residual rainwater traces, and then analyze the cleanliness after the wipers have performed a wiping operation based on the residual rainwater density. If the residual rainwater density is low after the wipers have performed a wiping operation, it indicates that the windshield surface is relatively clean, meaning the wipers are still in good condition. If the residual rainwater density is high, it indicates that there is a large amount of residual rainwater on the windshield surface, meaning the wipers may be in an aging state or require cleaning. When this embodiment determines that the wipers are in an aging state or require cleaning, it can control the abnormality warning component to issue an abnormality warning, allowing the driver to promptly replace or clean the wipers, effectively improving vehicle driving safety.

[0033] Specifically, in this embodiment, when analyzing rainwater residue in the windshield based on surface images, it can acquire an image of the wiper movement area in the windshield. After determining that the surface image is located within the wiper movement area image, it analyzes the first residual mark in the windshield based on the surface image from the first camera, and analyzes the second residual mark based on the surface image from the second camera. Then, it fuses the first and second residual marks to obtain the rainwater residue in the windshield. For example, as shown... Figure 4 As shown, this embodiment first uses a camera to determine the image of the wiper movement area during wiper operation. Then, it determines that the real-time acquired surface image is within the wiper movement area image before performing residual trace analysis. This ensures that the trace analysis process accurately reflects the performance status of the wipers. Specifically, this embodiment determines that the surface images acquired by both cameras are within the wiper movement area image, then analyzes the residual traces on the windshield based on the surface images acquired by the two cameras separately, and then fuses the two residual traces to obtain the rainwater residual traces. This effectively reduces the visual impact of a single camera and significantly improves the accuracy of the subsequent wiper performance status analysis process.

[0034] It is understood that this embodiment can also analyze the performance status of the windshield wipers based on the real-time rainfall data and surface images after acquiring them. Specifically, this embodiment can obtain a residual rainfall threshold and analyze the relationship between the real-time rainfall data and the residual rainfall threshold. If the real-time rainfall data is determined to be greater than or equal to the residual rainfall threshold, it indicates that a significant amount of rainwater remains on the windshield after the wipers have performed their operation, meaning the wipers may be in an aging state or require cleaning. The driver needs to perform appropriate operations on the wipers promptly to improve driving safety in rainy weather. If the real-time rainfall data is determined to be less than the residual rainfall threshold, it indicates that the rainwater on the windshield has been almost completely wiped away after the wipers have performed their operation, or that the rain sensor is malfunctioning. To further improve the accuracy of subsequent analysis, this embodiment can also analyze the residual rainwater traces on the windshield based on the surface images and analyze the performance status of the wipers based on these traces. Specifically, this embodiment can analyze the residual rainwater density based on the residual rainwater traces and then analyze the cleanliness of the windshield after the wipers have performed their operation based on the residual rainwater density. If the residual water density is low after the wipers have wiped the windshield, it indicates that the windshield surface is relatively clean, meaning the wipers are in good working order. Conversely, if the residual water density is high, it indicates a significant amount of residual rainwater on the windshield, suggesting the wipers may be aging or require cleaning. Therefore, this embodiment, by using real-time rainfall data collected by a rain sensor to determine when the residual water on the windshield is low after the wipers have wiped, further analyzes the surface image collected by the image generation component. This effectively reduces the error caused by a single detection component and improves the accuracy of subsequent analysis results.

[0035] It is understood that in the complete implementation of the method of this application embodiment, when the vehicle is driven in rainy weather, the windshield wipers can be automatically or manually controlled to enter the working state. Simultaneously, the rain sensor and image generation component are also controlled to enter the working state. The rain sensor collects real-time rainfall data on the windshield after the wipers have performed their operation, and the image generation component collects a surface image of the windshield after the wipers have performed their operation. Then, the amount of rainwater remaining on the windshield after the wipers have performed their operation is analyzed using the real-time rainfall data, and the amount of rainwater remaining reflects the performance of the windshield wipers. The system can be configured to: 1) analyze the residual rainwater density on the windshield surface after wiping operations using surface image analysis, and then use this density to reflect the wiper's performance status; or 2) analyze the amount of rainwater remaining on the windshield after wiping operations using real-time rainfall data, and then analyze the residual rainwater density on the windshield surface using surface image analysis, combining the amount and density of residual rainwater to reflect the wiper's performance status. This can effectively improve the accuracy of fault warnings, allowing drivers to promptly and accurately replace or clean the wipers, thus enhancing vehicle driving safety.
