Embodiments of the present disclosure 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 disclosure, and should not be construed as limiting the present disclosure.

The phase-locked loop frequency synthesizer and the control method thereof according to the embodiments of the present disclosure will be described below with reference to the accompanying drawings.

FIG1 is a flow chart of a method for controlling a vehicle windshield wiper according to an embodiment of the present disclosure. As shown in FIG1 , in some embodiments, the method for controlling a vehicle windshield wiper may include:

S101, performing a pressure object detection on the windshield of the vehicle to obtain the type of the pressure object when it is determined that there is a pressure object on the windshield.

Specifically, by detecting the pressure-bearing objects on the windshield of the vehicle, it is determined whether there is any pressure-bearing object on the windshield of the vehicle at the current moment. When it is determined that there is a pressure-bearing object on the windshield, the pressure-bearing object can be cleared through the subsequent control process of the present invention to ensure that the driver's vision is not blocked during driving.

S102, determining a target pressure according to the type of the pressurized object.

Optionally, when the types of the pressurized objects obtained are different, the determined target pressures may also be different.

Exemplarily, the pressurized object may include mud spots, rainwater, bird droppings, gum, watermarks, oil films, etc. It is understandable that mud spots and rainwater are easy-to-clean elements, while sticky elements such as bird droppings, gum, watermarks, and oil films are difficult-to-clean elements. Therefore, for pressurized objects of the type of easy-to-clean elements, the target pressure applied during the cleaning process should be less than the target pressure applied to pressurized objects of the type of difficult-to-clean elements. Therefore, it is necessary to first obtain the type of pressurized object through the above step S101, and then determine the target pressure to be applied to the windshield during the cleaning process according to the type of pressurized object. It should be noted that the above classification criteria for the types of pressurized objects are only exemplary, and can be set according to specific needs in actual situations, and no specific restrictions are made in the embodiments of the present disclosure.

S103, adjusting the pressure of the wiper on the windshield to a target pressure, so that the wiper wipes the windshield at the target pressure.

Optionally, after the target pressure is determined according to the type of the pressurized object, the target pressure needs to be applied to the windshield by a wiper and then wiped to clean the windshield.

According to the control method of the vehicle wiper of the embodiment of the present disclosure, when it is determined that there is a pressurized object on the windshield through pressurized object detection on the windshield of the vehicle, the type of the pressurized object is obtained, and the corresponding target pressure is determined according to the different types of pressurized objects. The target pressure is applied to the windshield through the wiper to achieve deep cleaning of the vehicle windshield, thereby ensuring safe driving and improving the driving experience.

In some embodiments of the present disclosure, as shown in FIG2 , the wiper 10 may include a wiper rocker arm 2 and a cleaning assembly 1, the cleaning assembly 1 includes a first cleaning portion 11, the first cleaning portion 11 is provided with an infrared sensor, and the vehicle is provided with a camera assembly. As a possible implementation, as shown in FIG5 , the pressure object detection on the windshield of the vehicle in the above-mentioned vehicle wiper control method embodiment may specifically include:

S201, when the wiper rocker arm drives the first cleaning unit to wipe the windshield, a reflection signal collected by the infrared pair sensor is obtained.

Specifically, because the first cleaning part 11 of the wiper 10 is provided with an infrared pair tube sensor, and it should be understood that the infrared pair tube sensor includes an infrared receiving tube and an infrared transmitting tube, when the wiper rocker arm 2 drives the first cleaning part 11 to wipe the windshield, the infrared transmitting tube in the infrared pair tube sensor emits infrared light to the surface of the windshield, and the infrared receiving tube receives the infrared light reflected back from the surface of the windshield, that is, obtains the reflection signal collected by the infrared pair tube sensor, and subsequently by analyzing the reflection signal, it can be determined whether there is a compressed object on the windshield.

Optionally, the number of infrared sensors provided on the first cleaning portion 11 is selected according to actual conditions (such as the brand of the wiper), and is not specifically limited in the embodiment of the present disclosure. For example, the first cleaning portion 11 may be a wiper blade. In actual applications, the wiper blade needs to sweep an area of more than 80% of the entire windshield. Therefore, for wipers of different brands, the area for deep cleaning may be different, and the number of infrared sensors provided on the first cleaning portion 11 in the embodiment of the present disclosure may be different.

S202, judging whether there is a pressure-bearing object on the windshield according to the reflected signal.

As a possible implementation manner, if the intensity of the reflected signal is within a preset intensity range, it is determined that there is a pressure object on the windshield.

Specifically, after obtaining the reflection signal collected by the infrared tube sensor, the intensity of the reflection signal is analyzed to determine whether the intensity of the reflection signal is within a preset intensity range. If so, it can be determined that there is a pressure object on the windshield. Alternatively, if the intensity of the reflection signal is not within the preset intensity range, it can be determined that there is no pressure object on the windshield.

Among them, the preset intensity range can be determined according to actual conditions. In some embodiments, the reflection signal intensity of the windshield when there are different types of pressure objects can be obtained in advance through experiments, and these signal intensities are integrated to obtain the preset intensity range in the embodiment of the present disclosure. Then, after obtaining the reflection signal collected by the infrared tube sensor, it is determined whether the intensity of the reflection signal is within the preset intensity range, and whether there is a pressure object on the windshield is determined based on the judgment result. It should be noted that the above method of obtaining the preset intensity range through experiments is only exemplary and does not serve as a specific limitation to the embodiment of the present disclosure.

Optionally, in some examples of the present disclosure, the reflection signal strength of the windshield when there is no pressure object can be obtained in advance through experiments, and this can be used as a reference. After obtaining the reflection signal collected by the infrared tube sensor, it is determined whether the reflection signal strength is consistent with the reflection signal strength of the windshield when there is no pressure object, thereby determining whether there is a pressure object on the windshield. It should be noted that the method proposed in this example to determine whether there is a pressure object on the windshield based on the reflection signal strength of the windshield when there is no pressure object is only exemplary and does not serve as a specific limitation on the embodiments of the present disclosure.

S203: If yes, obtain the image information of the windshield captured by the camera assembly.

That is to say, after determining that there is a pressure object on the windshield, it is necessary to determine the type of the pressure object. The image information of the windshield collected by the camera component in the embodiment of the present disclosure can be obtained, and the type of the pressure object can be determined by further analyzing the image information.

In some examples of the present disclosure, image information of the windshield may be collected by a driving recorder of the vehicle.

S204: Determine the type of the pressurized object according to the image information.

As a possible implementation method, after obtaining the image information of the windshield, the ROI (Region Of Interest) algorithm in image processing is used to intercept the area where the pressure-bearing object on the windshield is located from the image information of the windshield, and the type of the pressure-bearing object is identified for the area by an artificial intelligence algorithm. As an example, the identification of the type of pressure-bearing object by an artificial intelligence algorithm may include: before performing the control work of the embodiment of the present disclosure, obtaining the reflection signal intensity range when various types of pressure-bearing objects exist on the windshield through experiments in advance, and storing the type and reflection signal intensity range. In the actual application process, the reflection signal intensity of the windshield at the current moment is determined by the artificial intelligence algorithm. Which type of pressure-bearing object exists on the windshield within the intensity range, so as to determine the type of pressure-bearing object.

As another example, identifying the type of pressurized object through an artificial intelligence algorithm may include: before performing the control work of the embodiment of the present disclosure, conducting deep learning on different types of pressurized objects through an artificial intelligence algorithm and establishing a deep learning model. In the actual judgment process, the deep learning model may be used to determine the type of pressurized object.

It should be noted that the above method of determining the type of the pressurized object based on image information through an image processing algorithm combined with an artificial intelligence algorithm is only exemplary and does not serve as a limitation to the embodiments of the present disclosure.

Further, in some embodiments of the present disclosure, as shown in FIG. 2 , FIG. 3 and FIG. 4 , the cleaning assembly 1 further includes a second cleaning portion 12, the second cleaning portion 12 includes a cleaning arm 121 and a position adjustment device 122, and the position adjustment device 122 is used to adjust the position of the cleaning arm 121 relative to the windshield. As a feasible implementation, as shown in FIG. 6 , the control method of the vehicle wiper may further include:

S301, determining the position of the compressed object according to the image information.

S302, determining whether the position of the pressed object is outside the cleaning area of the cleaning arm.

S303: If yes, the position of the cleaning arm relative to the windshield is adjusted by controlling the position adjustment device so that the cleaning area of the cleaning arm covers the position of the pressed object.

Specifically, when the wiper arm 2 drives the first cleaning part 11 to wipe the windshield, it is judged according to the image information of the windshield that the position of the compressed object is outside the cleaning area of the cleaning arm 121, that is, the cleaning arm 121 cannot perform deep cleaning of the compressed object on the windshield at the current moment. Therefore, the position of the cleaning arm 121 relative to the windshield can be adjusted by the position adjustment device 122 until the cleaning area of the cleaning arm 121 can cover the position of the compressed object.

As an example, as shown in Figures 3 and 4, the position adjustment device 122 may include a position adjustment motor 1221, a screw rod 1222, a slider 1223 and a limit rod 1224. The adjustment motor 1221 is fixed to the switching component 3, and the adjustment motor 1221 is used to drive the screw rod 1222 to rotate. The slider 1223 is threadedly connected to the screw rod 1222, and the limit rod 1224 is fixed to the switching component 3. The extension direction of the limit rod 1224 is parallel to the screw rod 1222. The slider 1223 can be slidably penetrated in the screw rod 1222, and the cleaning arm 121 is connected to the slider 1223. Therefore, the screw rod 1222 is driven to rotate by the adjusting motor 1221, so that the slider 1223 moves along the length direction of the screw rod 1222 and the limit rod 1224, thereby driving the cleaning arm 121 to move relative to the windshield.

Furthermore, as shown in FIG5 , the second cleaning unit 12 further includes a pressure regulating device 123, and the pressure regulating device 123 is used to regulate the pressure of the cleaning arm 121 on the windshield. In some embodiments of the present disclosure, in order to make the cleaning process of the windshield more targeted and achieve a better cleaning effect, the control method of the vehicle wiper may further include: determining the target area according to the position of the pressure object; wherein, when the wiper 10 sweeps to the target area, the cleaning pressure of the cleaning arm 121 on the windshield is regulated to the target pressure by controlling the pressure regulating device 123, so that the cleaning arm 121 performs deep cleaning in the target area until there is no pressure object in the target area.

Specifically, after the position of the pressure object is determined according to the image information of the windshield, the target area can be further determined according to the position of the pressure object. Since there is a pressure object in the target area, local cleaning is required for the target area. The pressure regulating device 123 of the embodiment of the present disclosure can be used to adjust the pressure of the cleaning arm 121 on the windshield. Exemplarily, when the target area is partially cleaned, when the cleaning arm 121 cleans the target area, the cleaning pressure of the cleaning arm 121 on the windshield is controlled to be adjusted to the target pressure, that is, the cleaning arm 121 applies a pressure of the target pressure value to the windshield, so that the cleaning process of the windshield is more targeted and achieves a better cleaning effect. Therefore, when the attachments cleaned by the cleaning arm 121 are easier to clean, the pressure of the cleaning arm 121 on the windshield can be reduced to reduce the resistance of the cleaning arm 121 to sweep the windshield. When the attachments cleaned by the cleaning arm 121 are not easy to clean, the pressure of the cleaning arm 121 on the windshield can be increased to enhance the cleaning effect of the cleaning arm 121 on the windshield, so as to achieve a deep cleaning effect. Optionally, in order not to affect the driver's driving, during the cleaning process, it is also possible to detect in real time whether there are still compressed objects in the target area. When it is determined that there are no compressed objects in the target area, the scraping work in the target area can be stopped to improve the driving experience.

As an example, as shown in Figure 5, the pressure regulating device 123 is constructed as an electric push rod. The pressure regulating device 123 is constructed as an electric push rod. One end of the electric push rod is connected to the switching component 3, and the other end of the electric push rod is connected to the cleaning arm 121. In the deep cleaning state, the extension and retraction direction of the electric push rod is parallel to the normal of the windshield. The cleaning arm 121 can be pushed toward the windshield by the electric push rod to increase the pressure of the cleaning arm 121 on the windshield. The cleaning arm 121 can also be pushed away from the windshield by the electric push rod to reduce the pressure of the cleaning arm 121 on the windshield.

Furthermore, in some embodiments of the present disclosure, as shown in FIG7 , the control method of a vehicle wiper may further include:

S401, determining a target cleaning agent according to the type of the pressurized object.

Optionally, when the types of pressurized objects are different, the determined target cleaning agents may also be different. For example, for pressurized objects with easy-to-clean elements such as mud spots and rainwater, in order to reduce the amount of water and complexity of the cleaning process, the selected cleaning agent may be a diluted cleaning agent to facilitate rinsing; for pressurized objects with difficult-to-clean elements such as bird droppings, gum, watermarks, and oil films, in order to achieve deep cleaning, the selected cleaning agent may be a neutral cleaning agent to ensure the cleaning effect.

S402, spraying a target cleaning agent toward the location of the pressurized object.

Specifically, because the target pressure applied to the target area on the windshield has been determined according to the type of pressurized object in the above-mentioned embodiment, the target detergent is determined according to the type of pressurized object in this embodiment. That is, during cleaning, after the target detergent is sprayed onto the position of the pressurized object, the cleaning arm 121 is used to clean the target area at the target pressure, thereby achieving local deep cleaning.

As a feasible implementation, referring to Figures 2, 3 and 4, the wiper 10 may further include: a switching component 3, the wiper rocker arm is connected to the cleaning component 1 through the switching component 3, and the switching component 3 includes a switching motor. The control method of the vehicle wiper may further include: controlling the switching motor to work so that the cleaning component 1 switches the cleaning state.

Specifically, as shown in FIG. 2 , the cleaning assembly 1 in the disclosed embodiment may include a first cleaning portion 11 and a second cleaning portion 12, and the cleaning assembly 1 has a normal cleaning state in which the first cleaning portion 11 is attached to the windshield of the vehicle and a deep cleaning state in which the second cleaning portion 12 is attached to the windshield of the vehicle. It is understandable that the first cleaning portion 11 can be used to clean rainwater, mud spots and other attachments that are easy to clean, and the second cleaning portion 12 can be used to remove bird droppings, gum and other attachments that are adhesive on the windshield. Therefore, when the cleaning assembly 11 is in use, it is more likely to be in the normal cleaning state. In order to reduce the second cleaning portion 12 blocking the driver's line of sight when the cleaning assembly 11 is in the normal cleaning state, the volume of the second cleaning portion 12 can be smaller than the volume of the first cleaning portion 11. The second cleaning portion 12 adjusts the position of the cleaning arm 121 through the position adjustment device 122 to achieve targeted cleaning of the attachments and ensure the scraping area of the cleaning arm 121.

As an example, as shown in FIG. 2 , FIG. 3 and FIG. 4 , the switching assembly 3 includes a switching motor 31 and a connecting portion 32. The switching motor 31 is arranged at the free end of the wiper rocker arm 2 away from its swing center. The connecting portion 32 connects the output shaft of the switching motor 31, the first cleaning portion 11 and the second cleaning portion 12. The output shaft of the switching motor 31 drives the connecting portion 32 to rotate to control the cleaning assembly 11 to switch between the normal cleaning state and the deep cleaning state. The switching assembly 3 has a simple and reliable structure, is easy to implement, and has less obstruction to the driver's line of sight. In this example, the connecting portion 32 is an L-shaped structure, and the connecting portion 32 includes a first plate 321 and a second plate 322 connected to each other. The output shaft of the switching motor 31 and the second cleaning portion 12 can be connected to the first plate 321, and the first cleaning portion 11 can be connected to the second plate 322. The output shaft of the switching motor 31 can drive the connecting portion 32 to rotate forward or reverse a preset angle, so that one of the first cleaning portion 11 and the second cleaning portion 12 is attached to the windshield, and the other is separated from the windshield.

Optionally, the preset angle is 90 degrees, that is, when the cleaning assembly 11 is in a normal cleaning state, the thickness direction of the cleaning arm 121 is perpendicular to the normal direction of the windshield to reduce the blocking of the driver's line of sight by the cleaning arm 121.

To better explain the present disclosure, FIG8 is used as an example to further illustrate the control method of the vehicle wiper of the embodiment of the present disclosure. In this example, the control method of the wiper may include:

S601, obtaining a reflection signal collected by an infrared tube sensor provided on the first cleaning unit.

S602: Determine whether there is a compressed object on the windshield according to the reflected signal.

S603: Determine the position information of the pressure object according to the ROI algorithm.

S604, determining the type of the pressurized object according to an artificial intelligence algorithm.

S605: Determine a target pressure and a target cleaning agent according to the type of the pressurized object.

S606, controlling the vehicle multimedia screen to display deep cleaning selection prompt information for the user to select.

S607: If the user selects deep cleaning, the cleaning arm is driven according to the target pressure to perform deep cleaning on the windshield.

According to the control method of the vehicle wiper of the disclosed embodiment, when detecting a pressurized object, by judging whether the intensity of the reflected signal collected by the infrared pair sensor is within the preset intensity range, it is determined whether there is a pressurized object on the windshield, and the judgment logic is simple; when it is determined according to the judgment result that there is a pressurized object, the image information of the windshield collected by the camera assembly is analyzed to determine the type of the pressurized object, so that the analysis result of the pressurized object type is highly accurate. At the same time, after determining the type of the pressurized object, the target pressure and target cleaning agent can also be determined according to the type of the pressurized object, so as to achieve local deep cleaning of the windshield, ensure safe driving, and improve the driving experience.

Furthermore, an embodiment of the present disclosure provides an electronic device.

When the processor executes the program, a method for controlling a vehicle wiper as in the above-mentioned embodiment of the present disclosure is implemented.

Furthermore, an embodiment of the present disclosure provides a control device for a vehicle wiper.

In some embodiments, as shown in FIG9 , the control device 100 for a vehicle windshield wiper may include: an acquisition module 110, a determination module 120, and an adjustment module 130.
