[0002] In modern cars, windshield wipers ensure clear visibility for the driver in rainy or other wet conditions. However, wiper systems can also encounter some problems during operation, one of which is the so-called "dry wiping" phenomenon. Dry wiping refers to the wipers operating on a dry windshield, which not only generates noise but can also cause wiper blade wear and motor overload, thus shortening the lifespan of the wiper system and increasing maintenance costs. Summary of the Invention

[0003] In view of this, the purpose of this application is to provide a vehicle windshield wiper control method, device, electronic equipment and vehicle to avoid windshield wiper blade wear and motor overload caused by dry wiping.

[0005] In response to the start of the wiper system, process parameters during the wiping process of the wiper system are acquired, and the process parameters are used to determine whether a single wipe of the wiper system meets the preset dry wiping conditions.

[0006] In response to determining that a single wipe by the wiper device meets the preset dry wiping conditions, the number of consecutive wipes by the wiper device to meet the preset dry wiping conditions is determined during the wiping process, and the wiping state of the wiper device is determined to be a dry wiping state based on the number of consecutive wipes.

[0007] In response to determining that the wiper system is in dry wiping mode, the appropriate wiper protection strategy is executed based on the vehicle's speed.

[0008] Based on the same inventive concept, this application also provides a vehicle windshield wiper control device, comprising:

[0009] The acquisition module is configured to acquire process parameters during the wiping process of the wiper device in response to the start of the wiper device, and determine whether a single wiping of the wiper device meets the preset dry wiping conditions based on the process parameters.

[0010] The judgment module is configured to, in response to determining that a single wipe of the wiper device meets a preset dry wiping condition, determine the number of consecutive wipes during the wiping process that the wiper device meets the preset dry wiping condition, and determine whether the wiping state of the wiper device is a dry wiping state based on the number of consecutive wipes.

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0023] In modern automobiles, windshield wipers are a crucial safety feature, ensuring clear visibility for the driver in rainy or other wet conditions. However, wiper systems can encounter problems during operation, one of which is the so-called "dry wiping" phenomenon. Dry wiping refers to the wipers operating on a dry windshield, which not only generates noise but can also lead to wiper blade wear and motor overload, thus shortening the wiper's lifespan and increasing maintenance costs. Dry wiping typically occurs when the wipers are accidentally activated or continue operating after the windshield has dried following rain. This can be caused by a variety of factors, including sensor misreading, system malfunction, or improper operation. In traditional wiper systems, it is difficult to accurately detect and prevent dry wiping because they typically adjust wiper operation automatically based solely on rain sensor input, without real-time monitoring of the windshield's actual wetness.

[0024] Based on the above issues, the applicant discovered that: in response to the start of the wiper system, process parameters during the wiping process are acquired, and the system determines whether a single wipe meets preset dry wiping conditions based on these parameters; in response to determining that a single wipe meets the preset dry wiping conditions, the number of consecutive wipes required to meet these conditions is determined during the wiping process, and the wiper state is determined based on this number of consecutive wipes; in response to determining that the wiper state is dry wiping, a corresponding wiper protection strategy is executed based on the vehicle's speed; in dry wiping mode, friction between the wiper blades and the dry windshield may damage the windshield surface. Continuous monitoring and evaluation of the wiper process allows for more accurate identification of dry wiping conditions, avoiding misjudgments based on single events. By reducing unnecessary dry wiping, wiper blade wear can be reduced, thereby extending the wiper system's lifespan, improving its efficiency, and enhancing driving safety and comfort.

[0025] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0026] This application provides a method for controlling a vehicle windshield wiper device, such as... Figure 1 As shown, in some embodiments, the method is executed by a vehicle controller or a data processor independent of the vehicle controller; subsequent embodiments will use the vehicle controller as an example for illustration. The method includes:

[0027] S101. In response to the start of the wiper device, obtain the process parameters of the wiper device during the wiping process, and determine whether the wiper device meets the preset dry wiping conditions in a single wiping based on the process parameters.

[0028] In practice, when the wipers are activated, process parameters during the wiping process are monitored in real time. Based on these parameters, it is determined whether a single wipe meets preset dry wiping conditions. These preset dry wiping conditions are typically predefined based on experimental and actual vehicle usage data. If a single wipe meets these conditions, it is considered a dry wipe. For example, the first preset dry wiping condition can be determined based on the first duration the wipers are in a stopped position and the second duration from when they leave the stopped position to when they re-enter it. If the first duration is greater than the first preset duration and the second duration is greater than the second preset duration, then the single wipe meets the first preset dry wiping condition. Alternatively, the second preset dry wiping condition can be determined based on the bias voltage detected by the rain sensor during the wiping process. If the voltage difference between the bias voltage before and after the single wipe is less than a preset voltage difference, then the single wipe meets the second preset dry wiping condition. This judgment mechanism allows the wiper system to evaluate each wipe. If a single wipe meets the preset dry wiping conditions, the event is recorded, and the number of occurrences of meeting the preset dry wiping conditions begins to accumulate. This helps to more accurately identify potential dry wiping conditions, rather than relying on a single possible misjudgment. Through this response mechanism, the wiper system can not only improve its wiping performance but also extend its lifespan by reducing unnecessary wiping strokes and minimizing potential damage to the windshield. Furthermore, it provides data support for subsequent protective measures, enabling more appropriate actions to be taken based on actual vehicle driving conditions and wiper status, such as adjusting wiper speed, activating the washer system, or completely stopping the wipers.

[0029] S102. In response to determining that a single wipe of the wiper device meets the preset dry wiping conditions, during the wiping process, the number of consecutive wipes by the wiper device to meet the preset dry wiping conditions is determined, and the wiping state of the wiper device is determined to be a dry wiping state based on the number of consecutive wipes.

[0030] In specific implementation, when a single wipe is detected to meet the preset dry wiping conditions, the number of consecutive wipes required for the wiper device to meet the preset dry wiping conditions is determined during the wiping process. The wiping state of the wiper device is then determined based on the number of consecutive wipes. For example, if the number of consecutive wipes is greater than or equal to a first preset number, the wiper device is determined to be in a dry wiping state. This aims to avoid occasional misjudgments of a single dry wipe affecting the determination of the dry wiping state, thereby improving the accuracy and reliability of the judgment.

[0031] S103. In response to determining that the wiping state of the windshield wiper is dry wiping, a corresponding windshield wiper protection strategy is executed according to the vehicle's driving speed.

[0032] In practice, when the windshield wipers are determined to be in dry wiping mode, corresponding wiper protection strategies will be implemented to optimize wiper usage and protect the vehicle. Vehicle speed is typically considered, as it directly impacts the wiping effectiveness and necessity of the wipers. When the vehicle is traveling at low speeds (e.g., in urban traffic or congested conditions), if the wipers are in dry wiping mode, completely stopping their operation will not affect driving safety, even with minor contaminants on the windshield, and will prevent additional wear on the wiper blades and windshield. Conversely, when the vehicle is traveling at high speeds, wiper operation is necessary to maintain good driver visibility. In this case, if dry wiping is detected, the windshield washer fluid can be activated, spraying a small amount of cleaning fluid to help the wipers more effectively remove potential contaminants while reducing wear on the wiper blades, thus providing a more efficient and safer driving experience.

[0033] In this embodiment, during dry wiping, friction between the wiper blades and the dry windshield can damage the windshield surface. Continuously monitoring and evaluating the wiping process of the wiper system allows for more accurate identification of dry wiping conditions, avoiding misjudgments based on single events. By reducing unnecessary dry wiping, wiper blade wear can be reduced, thereby extending the lifespan of the wiper system, improving its efficiency, and enhancing driving safety and comfort.

[0034] In some embodiments, such as Figure 2 As shown, the process parameters include a first duration for the wiper to be in the stopped position and a second duration for the wiper to move out of the stopped position and then back into the stopped position. The preset dry wiping conditions include a first preset dry wiping condition. Determining whether a single wiper stroke meets the preset dry wiping conditions based on the process parameters includes:

[0035] S201. Determine whether a single wipe of the wiper device meets the first preset dry wiping condition based on the first duration and the second duration.

[0036] In practice, the first duration refers to the length of time the wiper unit remains in the stopped position during each wiping cycle. In wiper operation, the stopped position is the state where the wiper unit returns to its starting position after completing a wiping motion, typically located below the windshield. The second duration refers to the time required for the wiper unit to move from one stopped position, complete the entire wiping action, and return to the stopped position. The second duration includes the entire process of the wiper unit starting its operation from the stopped position, wiping the entire windshield, and then returning to the stopped position.

[0037] S202. In response to the first duration being greater than the first preset duration and the second duration being greater than the second preset duration, it is determined that a single wipe by the wiper device satisfies the first preset dry wiping condition.

[0038] In practice, the operating status of the windshield wiper system is evaluated using a first and a second time interval. The first preset dry wiping condition involves a first preset time interval and a second preset time interval, both set based on typical wiping cycles under normal wet conditions. When the wipers are running on a dry windshield, the lack of lubricating moisture increases friction between the wipers and the glass, causing both the first and second preset time intervals to lengthen, as the wipers require more force and time to complete the same wiping path. When the first time interval is detected to be longer than the set first preset time interval, and the second time interval is also longer than the set second preset time interval, it is determined that the wipers have met the dry wiping condition for that wiping cycle. This identifies wiping behavior under conditions lacking necessary moisture, and corresponding measures are taken, such as reducing the wiping frequency, activating the washer system, or alerting the driver to intervene, to protect the wipers and the windshield while ensuring driving safety.

[0039] In this embodiment, dry wiping is determined by both a first duration and a second duration, allowing for more accurate identification of actual dry wiping conditions. By avoiding unnecessary wiping in dry conditions, the motor and mechanical components of the wiper system can be protected, extending their lifespan. In dry wiping mode, wiper effectiveness is significantly reduced; timely identification and intervention ensure effective visibility when needed, improving driving safety. Reducing unnecessary dry wiping actions can also decrease noise and irregular scratches on the windshield, enhancing passenger comfort.

[0040] In some embodiments, such as Figure 3 As shown, the vehicle includes a rain sensor, the process parameters include the bias voltage detected by the rain sensor during wiping, and the preset dry wiping conditions include a second preset dry wiping condition; determining whether a single wipe by the wiper device meets the preset dry wiping conditions based on the process parameters includes:

[0041] S301. Determine whether the wiper device meets the second preset dry wiping condition in a single wiping stroke based on the bias voltage.

[0042] In practice, the rain sensor controls the automatic start and stop of the windshield wipers by detecting raindrops on the windshield. The rain sensor typically uses changes in bias voltage to detect the moisture level on the windshield surface. The bias voltage is the baseline voltage of the rain sensor when there are no external influences; when raindrops or water fall on the sensor's detection area, it causes a change in the bias voltage. The second preset dry wiping condition involves the change in bias voltage detected by the rain sensor.

[0043] S302. If the voltage difference between the bias voltage before and after a single wipe is less than a preset voltage difference, then the wiper device is determined to meet the second preset dry wiping condition for a single wipe.

[0044] In practice, under normal circumstances, if there is sufficient moisture on the windshield, the wiper will cause a significant change in the bias voltage after wiping, because the presence and movement of moisture alters the light refraction and reflection conditions in front of the rain sensor. However, under dry conditions, even after the wiper passes, the change in bias voltage will be very small or almost negligible, because the dry glass surface has minimal impact on light refraction and reflection. Therefore, the second preset dry wiping condition is determined by comparing the voltage difference before and after a single wipe. If the voltage difference is less than the preset voltage difference, the wipe is considered a dry wipe. The preset voltage difference is set based on experimental or actual usage data. Typically, the preset voltage difference is the difference between the bias voltage detected by the rain sensor before and after the wiper cleans the windshield, ensuring accurate identification of dry and wet conditions.

[0045] In this embodiment, by detecting the change in bias voltage of the rain sensor during the wiping process, the actual condition of the windshield can be determined more accurately, thereby avoiding dry wiping in dry conditions. In dry wiping mode, friction between the wiper blades and the dry windshield causes wear on both the wiper blades and the glass surface. By detecting the bias voltage, dry wiping can be identified in a timely manner, and measures such as reducing the wiper speed or pausing the wipers can be taken to reduce wear. Unnecessary energy consumption is avoided when the wipers are not needed, thus improving the vehicle's energy efficiency. Avoiding the use of wipers in dry conditions reduces potential damage to the windshield, maintaining its clarity and integrity.

[0046] In some embodiments, determining whether the wiping state of the wiper device is in a dry wiping state based on the number of consecutive wiping cycles includes:

[0047] If the number of consecutive wiping strokes is greater than or equal to a first preset number, the wiper device is determined to be in dry wiping mode.

[0048] In practice, the number of consecutive wiping cycles refers to the number of times the wiper system runs continuously under conditions without significant moisture, used to more accurately determine the actual operating status of the wiper system. If the wiper system runs repeatedly on a dry windshield, this usually indicates a false trigger (e.g., due to sensor malfunction or misreading) or an abnormality caused by external conditions (such as dust or other contaminants). If the number of consecutive wiping cycles is greater than or equal to a first preset number (exemplarily, the first preset number can be set to 3 times), it is determined that the wiper system is in a dry wiping state. At this time, to prevent further damage to the wiper blades and windshield, the operation of the wiper system can be stopped. Alternatively, the normal function of the wiper system can be restored by activating the washer system to increase the humidity of the windshield. A warning can also be issued to the driver via the vehicle's dashboard or information display, indicating that there may be a problem with the wiper system and that it needs to be checked or manually intervened. Through this continuous monitoring and intelligent response mechanism, the wiper system can effectively reduce unnecessary wiping, extend the service life of the wiper system, and maintain good driving visibility, thereby improving driving safety and comfort.

[0049] In this embodiment, by continuously monitoring the number of consecutive wiping strokes of the wiper system under dry wiping conditions, it is possible to more accurately determine whether the windshield is dry, thereby avoiding misjudgments. Once dry wiping is confirmed, the wiper system can be stopped promptly or other measures can be taken to reduce wear on the wiper blades and windshield caused by dry wiping. Judging based on the number of consecutive wiping strokes effectively improves the efficiency and lifespan of the wiper system, reduces unnecessary wear, enhances driving safety and comfort, and lowers maintenance costs.

[0050] In some embodiments, the execution of the corresponding wiper protection strategy based on the vehicle's travel speed includes:

[0051] If the vehicle's speed is lower than the preset speed, the strategy of turning off the windshield wipers will be implemented.

[0052] In practice, vehicle speed is a crucial factor in determining the implementation of the wiper protection strategy. By sensing the vehicle's speed and comparing it to a preset speed (for example, the preset speed could be set to 10 km / h), adjustments are made to optimize wiper operation, reduce unnecessary wear, and improve driving safety. When the vehicle speed is lower than the preset speed, the wipers are turned off. This is because at low speeds, if the wipers are in dry wiping mode, completely stopping their operation ensures that even minor contaminants on the windshield will not affect driving safety and avoids additional wear on the wiper blades and windshield.

[0053] If the vehicle's speed is greater than or equal to a preset speed, the strategy of activating the washer system to spray water onto the windshield is executed.

[0054] In practice, when a vehicle is traveling at high speed, the driver requires extremely clear visibility ahead. Any obstructions in the line of sight, such as dust, dirt, or dried water streaks, can affect driving safety. Therefore, keeping the windshield clean is particularly important. To maintain good visibility for the driver, the operation of the windshield wipers is necessary. Activating the washer fluid system to spray water onto the windshield can effectively remove potential contaminants while reducing wear on the wiper blades, thus providing a more efficient and safer driving experience.

[0055] In this embodiment, maintaining good visibility is crucial when driving at high speeds. By controlling the wipers and washer system, the windshield is kept clean, reducing traffic accidents caused by poor visibility. When driving at low speeds, if the windshield is relatively dry, turning off the wipers can reduce unnecessary wear, extend the wiper's lifespan, and save on vehicle energy consumption.

[0056] In some embodiments, after executing the strategy of activating the washer fluid sprayer to spray water onto the windshield, the method further includes:

[0057] In response to the number of consecutive swiping cycles being greater than or equal to a second preset number, the vehicle's air conditioning is turned on and the windshield is heated, wherein the second preset number is greater than the first preset number.

[0058] In practice, when the number of consecutive swiping cycles reaches a second preset number (for example, the second preset number is set to 8 times), it indicates that spraying water on the windshield with the washer fluid cannot effectively remove contaminants. In this case, the vehicle's air conditioning is turned on to heat the windshield, assisting in cleaning. Setting the second preset number to be greater than the first preset number ensures that basic swiping and washing operations have been sufficiently attempted before heating the windshield, saving energy, avoiding overreaction, and ensuring adequate response when needed. This not only improves driving safety but also significantly enhances driving comfort by preventing obstructed vision.

[0059] In this embodiment, when the washing machine cannot effectively remove contaminants from the windshield by spraying water, the vehicle's air conditioning is turned on to heat the windshield, ensuring the windshield is clean and reducing traffic accidents caused by poor visibility.

[0060] In some embodiments, turning on the vehicle's air conditioning and heating the windshield includes:

[0061] The heating temperature of the vehicle's air conditioning is determined based on the difference between the number of consecutive scraping strokes and the second preset number of strokes.

[0062] In practice, the frequency difference indicates how many times the wiper system continues to operate after reaching a second preset number of cycles. The magnitude of the frequency difference can be considered an indicator of the severity of the problem on the windshield. A larger frequency difference may indicate that the contaminants on the windshield are more stubborn and require more intense heating measures.

[0063] If the difference in the number of heating cycles is less than a preset difference in the number of heating cycles, then the heating temperature is determined to be the first heating temperature.

[0064] In practice, when the difference in the number of times is less than the preset difference in the number of times (for example, the preset difference in the number of times is set to 10 times), it indicates that the problem of pollutants on the windshield is relatively minor, and a lower heating temperature is usually sufficient to solve the problem. There is no need to use a higher temperature to avoid unnecessary energy consumption.

[0065] If the difference in the number of heating cycles is greater than or equal to a preset difference in the number of heating cycles, then the heating temperature is determined to be a second heating temperature; wherein the second heating temperature is greater than the first heating temperature.

[0066] In specific implementation, when the difference in the number of times is greater than or equal to the preset difference in the number of times, it indicates that even after multiple swiping, the pollutants on the windshield have not been effectively removed and a higher temperature is needed to quickly clean the pollutants in order to restore clear vision. In this case, the heating temperature is determined to be the second heating temperature, which is greater than the first heating temperature.

[0067] In this embodiment, precise control of the heating temperature avoids unnecessary energy waste, achieving energy efficiency. Increasing the heating temperature helps to more effectively remove stubborn pollutants and restore the clarity of the windshield. Timely removal of pollutants from the windshield ensures clear visibility for the driver, reducing the risk of traffic accidents caused by obstructed vision. Appropriate control of the heating temperature avoids overheating and damage to the windshield and wipers, extending their service life.

[0068] It should be noted that the method in this embodiment can be executed by a single device, such as a computer or server. The method can also be applied in a distributed scenario, where multiple devices cooperate to complete the task. In such a distributed scenario, one of these devices may execute only one or more steps of the method in this embodiment, and the multiple devices will interact with each other to complete the method described.

[0069] It should be noted that the above description describes some embodiments of this application. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be performed in a different order than that shown in the above embodiments and still achieve the desired result. Furthermore, the processes depicted in the drawings do not necessarily require a specific or sequential order to achieve the desired result.
