[0021] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0022] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0023] In the related art, in modern cars, the wiper device is an important safety feature that ensures a clear view for the driver in rainy days or other wet conditions. However, the wiper device may also encounter some problems in operation, one of which is the so-called "dry wiping" phenomenon. Dry wiping refers to the operation of the wiper device on a dry windshield, which not only produces noise, but may also cause wear of the wiper blades and overload of the motor, thereby shortening the service life of the wiper device and increasing maintenance costs. The dry wiping phenomenon usually occurs when the wiper device is mistakenly started or the wiper device is still running when the windshield is already dry after rain. This situation may be caused by a variety of factors, including sensor misreading, system failure or improper operation. In traditional wiper devices, it is difficult to accurately detect and prevent dry wiping because the operation of the wiper device is usually automatically adjusted based on the input of the rain sensor without real-time monitoring of the actual wetness of the windshield.

[0024] Based on the above problems, the applicant found that: in response to the start of the wiper device, the process parameters of the wiper device wiping process are obtained, and whether the single wiping of the wiper device meets the preset dry wiping condition is determined according to the process parameters; in response to determining that the single wiping of the wiper device meets the preset dry wiping condition, the number of continuous wiping times during which the wiper device meets the preset dry wiping condition is determined during the wiping process, and whether the wiping state of the wiper device is a dry wiping state is determined according to the continuous wiping number; in response to determining that the wiping state of the wiper device is a dry wiping state, a corresponding wiper protection strategy is executed according to the driving speed of the vehicle; in the dry wiping state, the friction between the wiper blade and the dry windshield may cause damage to the surface of the windshield, and the dry wiping state can be more accurately identified by continuously monitoring and evaluating the wiping process of the wiper device, thereby avoiding misjudgment based on a single event. By reducing unnecessary dry wiping, the wear of the wiper blade can be reduced, thereby extending the service life of the wiper device, improving the use efficiency of the wiper device, and also improving driving safety and comfort.

[0025] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0026] The present application provides a vehicle wiper device control method, such as Figure 1 As shown, in some embodiments, the method is executed by a vehicle controller or a data processor independently provided by the vehicle controller. The subsequent embodiments are all illustrated by taking the vehicle controller as an example; the method includes:

[0027] S101, in response to the wiper device being started, obtaining process parameters of the wiper device during a wiping process, and determining whether a single wiping of the wiper device meets a preset dry wiping condition according to the process parameters;

[0028] In specific implementation, when the wiper device is started, the process parameters of the wiper device wiping process are monitored in real time, and whether the wiper device meets the preset dry wiping condition for a single wipe is determined according to the process parameters. The preset dry wiping condition is usually a condition predefined based on experiments and actual vehicle usage data. When the wiper device meets the preset dry wiping condition for a single wipe, the single wipe is considered to be dry wiping. For example, whether the wiper device meets the first preset dry wiping condition for a single wipe is determined according to the first time length of the wiper device being in the stop position and the second time length of the wiper device driving out of the stop position to the next time driving into the stop position; if the first time length is greater than the first preset time length and the second time length is greater than the second preset time length, it is determined that the wiper device meets the first preset dry wiping condition for a single wipe. Alternatively, whether the wiper device meets the second preset dry wiping condition for a single wipe is determined according to the bias voltage detected by the rain sensor during the wiping process; if the voltage difference between the bias voltage before the single wipe and the bias voltage after the single wipe is less than the preset voltage difference, it is determined that the wiper device meets the second preset dry wiping condition for a single wipe. This judgment mechanism enables the wiper device to evaluate each time it wipes. If it is detected that a single wipe meets the preset dry wipe condition, this event will be recorded and the number of occurrences that meet the preset dry wipe condition will begin to accumulate, which helps to more accurately identify potential dry wipe conditions, rather than just based on a possible misjudgment. Through this response mechanism, the wiper device can not only improve its wiping effect, but also extend the service life of the wiper device by reducing the number of unnecessary wipes and reduce potential damage to the windshield. In addition, it also provides data support for subsequent protective measures, and can take more appropriate measures based on the actual vehicle driving conditions and wiper status, such as adjusting the wiper speed, starting the washing system, or completely stopping the wiper device.

[0029] S102, in response to determining that a single wiping of the wiper device satisfies a preset dry wiping condition, determining the number of continuous wiping times during which the wiper device satisfies the preset dry wiping condition, and determining whether the wiping state of the wiper device is a dry wiping state according to the number of continuous wiping times;

[0030] In specific implementation, after detecting that a single wiping meets the preset dry wiping condition, the number of continuous wiping times during which the wiper device meets the preset dry wiping condition is determined during the wiping process, and whether the wiping state of the wiper device is the dry wiping state is judged based on the continuous wiping number; for example, when the number of continuous wiping times is greater than or equal to the first preset number, it is determined that the wiper device is in the dry wiping state, so as to avoid the influence of occasional misjudgment of a single dry wiping on the judgment of the dry wiping state, thereby improving the judgment accuracy and reliability.

[0031] S103: In response to determining that the wiping state of the wiper device is the dry wiping state, executing a corresponding wiper protection strategy according to a driving speed of the vehicle.

[0032] In specific implementation, when it is determined that the wiping state of the wiper device is a dry wiping state, a corresponding wiper protection strategy will be further adopted to optimize the use of the wiper device and protect the vehicle. The driving speed of the vehicle is usually considered because the driving speed has a direct impact on the wiping effect and necessity of the wiper device. When the vehicle is traveling at a low speed (for example, in urban traffic or congestion conditions), if the wiper device is in a dry wiping state, it is chosen to completely stop the operation of the wiper device. Even if there are a few contaminants on the windshield, it will not affect driving safety, and it can avoid additional wear on the wiper blades and windshield. Conversely, when the vehicle is traveling at a high speed, in order to maintain a good line of sight for the driver, the operation of the wiper device is necessary. In this case, if the dry wiping state is detected, the windshield washing device can be started, and a small amount of cleaning fluid can be sprayed to help the wiper device more effectively remove possible contaminants, while reducing the wear on the wiper blades, thereby providing a more efficient and safer driving experience.

[0033] In this embodiment, in the dry wiping state, the friction between the wiper blade and the dry windshield may cause damage to the windshield surface. By continuously monitoring and evaluating the wiping process of the wiper device, the dry wiping state can be more accurately identified, avoiding misjudgment based on a single event. By reducing unnecessary dry wiping, the wear of the wiper blade can be reduced, thereby extending the service life of the wiper device, improving the use efficiency of the wiper device, and also improving driving safety and comfort.

[0034] In some embodiments, Figure 2 As shown, the process parameters include a first time duration of the wiper device being in the stop position and a second time duration of the wiper device moving out of the stop position and moving into the stop position next time, and the preset dry scraping condition includes a first preset dry scraping condition; and judging whether a single scraping of the wiper device satisfies the preset dry scraping condition according to the process parameters includes:

[0035] S201, determining whether a single wipe of the wiper device satisfies a first preset dry-wiping condition according to the first time duration and the second time duration;

[0036] In specific implementation, the first duration refers to the length of time that the wiper device is in the stop position in each wiping cycle. In the operation of the wiper device, the stop position is the state where the wiper device returns to the starting position after completing a wiping operation, usually located below the windshield. The second duration refers to the time required for the wiper device to move out of a stop position, complete the entire wiping action, and return to the stop position again. The second duration includes the entire process of the wiper device starting from the stop position, wiping the entire windshield, and then returning to the stop position.

[0037] S202: In response to the first duration being greater than a first preset duration and the second duration being greater than a second preset duration, determining that a single wipe of the wiper device satisfies a first preset dry-wiping condition.

[0038] In specific implementation, the operation state of the wiper device is evaluated by the first time length and the second time length. The first preset dry wiping condition involves the first preset time length and the second preset time length. The first preset time length and the second preset time length are set based on a typical wiping cycle under normal wet conditions. When the wiper device is running on a dry windshield, due to the lack of lubricating moisture, the friction of the wiper device on the glass will increase, resulting in the first preset time length and the second preset time length becoming longer, because the wiper device needs more force and time to complete the same wiping path. When it is detected that the first time length is greater than the set first preset time length, and the second time length is also greater than the second preset time length, it is determined that the wiper device meets the dry wiping condition in this wiping, and the wiping behavior in the absence of necessary wet conditions is identified, so that corresponding measures are taken, such as reducing the wiping frequency, starting the washing system, or reminding the driver to intervene, so as to protect the wiper device and the windshield, while ensuring driving safety.

[0039] In this embodiment, by judging dry scraping by the first time length and the second time length, the actual dry scraping situation can be more accurately identified. By avoiding unnecessary scraping in dry conditions, the motor and mechanical components of the wiper system can be protected and their service life can be extended. In the dry scraping state, the wiper effect will be greatly reduced. By timely identification and taking measures, it can be ensured that an effective field of view is provided when needed, thereby improving driving safety. Reducing unnecessary dry scraping actions can reduce noise and irregular scratches on the windshield, thereby improving ride comfort.

[0040] In some embodiments, Figure 3 As shown, the vehicle includes a rain sensor, the process parameter includes a bias voltage detected by the rain sensor during the wiping process, and the preset dry wiping condition includes a second preset dry wiping condition; and judging whether a single wiping of the wiper device satisfies the preset dry wiping condition according to the process parameter includes:

[0041] S301, judging whether a single wipe of the wiper device meets a second preset dry-wiping condition according to the bias voltage;

[0042] In a specific implementation, the rain sensor controls the automatic start and stop of the wiper device by detecting raindrops on the windshield. The rain sensor usually uses the change of bias voltage to sense the moisture on the surface of the windshield. The bias voltage refers to the baseline voltage of the rain sensor when there is no external influence. When raindrops or moisture fall on the detection area of ​​the rain sensor, it will cause a change in the bias voltage. The second preset dry wiping condition involves the change of the bias voltage detected by the rain sensor.

[0043] S302: In response to the voltage difference between the bias voltage before the single wiping and the bias voltage after the single wiping being less than a preset voltage difference, determining that the single wiping of the wiper device satisfies a second preset dry wiping condition.

[0044] In specific implementation, under normal circumstances, if there is enough moisture on the windshield, the wiper device will cause a significant change in the bias voltage after wiping, because the presence and movement of moisture changes the light refraction and reflection conditions in front of the rain sensor. However, under dry conditions, even if the wiper device wipes, the change in the bias voltage will be very small or almost unchanged, because the dry glass surface has little effect on the refraction and reflection of light. Therefore, by comparing the voltage difference between the bias voltage before and after a single wipe, it is determined whether the second preset dry wipe condition is met. If the voltage difference is less than the preset voltage difference, the wipe is determined to be a dry wipe. The preset voltage difference is set based on experimental or actual use data. Usually, the preset voltage difference is the difference between the bias voltage detected by the rain sensor before the wiper device cleans the rain on the windshield and the bias voltage detected by the rain sensor after cleaning, so as to ensure that dry and wet conditions can be accurately identified.

[0045] In this embodiment, by detecting the change in the bias voltage of the rain sensor during the wiping process, the actual situation on the windshield can be judged more accurately, thereby avoiding dry wiping under dry conditions. In the dry wiping state, the friction between the wiper blade and the dry windshield will cause wear on the wiper blade and the glass surface. By detecting the bias voltage, the dry wiping state can be identified in time and measures can be taken, such as reducing the wiper speed or pausing the wiper, to reduce wear. In the case where the wiper device is not required to work, unnecessary energy consumption is avoided, thereby improving the energy efficiency of the vehicle. Avoiding the use of the wiper device in a dry state can reduce potential damage to the windshield and maintain the clarity and integrity of the windshield.

[0046] In some embodiments, judging whether the wiping state of the wiper device is a dry wiping state according to the continuous wiping times includes:

[0047] In response to the number of continuous wiping times being greater than or equal to a first preset number, it is determined that the wiper device is in a dry wiping state.

[0048] In specific implementation, the number of continuous wiping refers to the number of times the wiper device operates continuously without obvious wet conditions, which is used to more accurately judge the actual operating state of the wiper device. If the wiper device operates on a dry windshield for multiple times in a row, this usually indicates an abnormality caused by false triggering (for example, due to sensor failure or misreading) or external conditions (such as dust or other pollutants). If the number of continuous wiping is greater than or equal to the first preset number (exemplarily, the first preset number can be set to 3 times), it is determined that the wiper device is in a dry wiping state. At this time, in order to prevent further damage to the wiper blade and the windshield, the operation of the wiper device can be stopped. Or try to increase the humidity of the windshield by activating the washing device to restore the normal function of the wiper device. A warning can also be issued to the driver through the vehicle's dashboard or information display screen, indicating that there may be a problem with the wiper device and that inspection or manual intervention is required. Through this continuous monitoring and intelligent response mechanism, the wiper device can effectively reduce unnecessary wiping, extend the service life of the wiper device, and maintain a good driving line of sight, thereby improving driving safety and comfort.

[0049] In this embodiment, by continuously monitoring the number of continuous wiping times of the wiper device in the dry wiping state, it is possible to more accurately determine whether the windshield is dry, thereby avoiding misjudgment. After confirming the dry wiping state, the wiper device can be stopped in time or other measures can be taken to reduce the wear of the wiper blade and the windshield caused by dry wiping. Judgment based on the number of continuous wiping times can effectively improve the use efficiency and life of the wiper device, reduce unnecessary wear, improve driving safety and comfort, and reduce maintenance costs.

[0050] In some embodiments, executing a corresponding wiper protection strategy according to the driving speed of the vehicle includes:

[0051] In response to the vehicle's driving speed being less than a preset driving speed, executing a strategy for closing the wiper device;

[0052] In specific implementation, the driving speed of the vehicle is one of the important factors that determine the implementation of the wiper protection strategy. By sensing the driving speed of the vehicle and comparing it with the preset driving speed (for example, the preset driving speed can be set to 10KM / h), corresponding adjustments are made to optimize the use of the wiper device, reduce unnecessary wear, and improve driving safety. When the driving speed of the vehicle is less than the preset driving speed, the strategy of shutting down the wiper device is executed, because when driving at a low speed, if the wiper device is in a dry wiping state, choosing to completely stop the operation of the wiper device will not affect driving safety even if there are a few contaminants on the windshield, and it can avoid additional wear on the wiper blades and the windshield.

[0053] In response to the vehicle's driving speed being greater than or equal to a preset driving speed, a strategy of turning on the washing device to spray water on the windshield is executed.

[0054] In practice, when the vehicle is driving at high speed, the driver has extremely high requirements for the clarity of the front line of sight. Any obstacles in the line of sight, such as dust, dirt or dry water marks, may affect driving safety. Therefore, it is particularly important to keep the windshield clean. In order to maintain the driver's good vision, the operation of the wiper device is necessary. The strategy of turning on the washing device to spray water on the windshield can be implemented to effectively remove possible contaminants and reduce the wear on the wiper blades, thereby providing a more efficient and safer driving experience.

[0055] In this embodiment, when driving at high speed, it is very important to maintain a good line of sight. By controlling the wiper device and the washing device, the windshield is kept clean, reducing traffic accidents caused by poor line of sight. When driving at low speed, if the windshield is relatively dry, turning off the wiper device can reduce unnecessary wear, extend the service life of the wiper device, and save energy consumption of the vehicle.

[0056] In some embodiments, after executing the strategy of starting the washing device to spray water on the windshield, the method further includes:

[0057] In response to the number of continuous wiping times being greater than or equal to a second preset number, the in-vehicle air conditioner is turned on and the windshield is heated, and the second preset number is greater than the first preset number.

[0058] In specific implementation, when it is detected that the number of continuous scraping and wiping reaches the second preset number (for example, the second preset number is set to 8 times), it indicates that starting the washing device to spray water on the windshield cannot effectively remove the pollutants on the windshield, then the air conditioner in the car is turned on to heat the windshield to assist in cleaning the windshield. The second preset number is set to be greater than the first preset number to ensure that the basic scraping and washing operations have been fully tried before taking the measure of heating the windshield, saving energy and avoiding overreaction, while ensuring that sufficient response measures are provided when needed, which not only improves driving safety, but also greatly improves driving comfort by preventing obstruction of vision.

[0059] In this embodiment, when the washing device cannot effectively remove pollutants on the windshield by spraying water on the windshield, the air conditioner in the car is turned on to heat the windshield to ensure that the windshield is clean and reduce traffic accidents caused by poor visibility.

[0060] In some embodiments, turning on the air conditioner in the vehicle and heating the windshield includes:

[0061] Determining a heating temperature of the air conditioner in the vehicle according to a difference between the number of continuous scraping times and a second preset number of times;

[0062] In a specific implementation, the number difference value indicates the number of times the wiper device continues to operate after reaching the second preset number of times. The size of the number difference value can be regarded as an indicator of the severity of the problem on the windshield. A larger number difference value may indicate that the contaminants on the windshield are more stubborn and require more intensive heating measures.

[0063] In response to the number difference being less than a preset number difference, determining the heating temperature to be a first heating temperature;

[0064] In specific implementation, when the number difference is less than the preset number difference (exemplarily, the preset number difference is set to 10 times), it indicates that the pollutant problem 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] In response to the number difference being greater than or equal to a preset number difference, 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 number difference is greater than or equal to the preset number difference, it indicates that even after multiple scraping and wiping, the pollutants on the windshield have not been effectively removed, and a higher temperature heating is required to quickly clean the pollutants to restore a clear view. In this case, the heating temperature is determined to be the second heating temperature, and the second heating temperature is greater than the first heating temperature.

[0067] In this embodiment, unnecessary energy waste is avoided by precisely controlling the heating temperature, thereby achieving energy saving and high efficiency. Increasing the heating temperature helps to more effectively remove stubborn pollutants and restore the clarity of the windshield. Timely removal of pollutants on the windshield ensures a clear view for the driver and reduces the risk of traffic accidents caused by obstructed vision. Appropriately controlling the heating temperature avoids damage to the windshield and wipers due to overheating, thereby extending their service life.

[0068] It should be noted that the method of the embodiment of the present application can be performed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present application, and the multiple devices will interact with each other to complete the described method.
