Description

Technical Field

[0001] The embodiments of the present application relate to the field of vehicle control technology, and relate to but are not limited to a wiper control method and device, equipment, and storage medium. Background Art

[0002] With the rapid development of intelligent vehicle technology, automotive features continue to innovate, significantly improving performance. As a key component for ensuring a clear driver's field of view and driving safety, the evolution of windshield wiper control methods has attracted considerable attention.

[0003] In traditional car wiper control, when the wiper wipes the stains on the windshield, the wiper will clean and wipe the entire windshield, that is, the wiper needs to complete the entire wiping stroke, resulting in the wiper not only cleaning and wiping the area with stains, but also cleaning and wiping other areas of the windshield without stains. As a result, the wiper assembly has a larger wiping area when wiping stains, causing the wiper to wear out faster and have a shorter service life. Summary of the Invention

[0004] In view of this, the wiper control method, device, equipment, and storage medium provided in the embodiments of the present application can control the wiper. The wiper control method, device, equipment, and storage medium provided in the embodiments of the present application are implemented as follows:

[0005] In one aspect of an embodiment of the present application, a wiper control method is provided, which is applied to a vehicle, wherein the vehicle includes wipers, a windshield, and a steering wheel, wherein a sensor is provided on the steering wheel. The method includes:

[0006] determining a wiping mode of the wiper in response to a first operation on the sensor;

[0007] When the wiping mode of the wiper is a custom wiping mode, in response to an operation of sliding a target sliding area on the sensor, a target wiping area is determined according to the target sliding area, the target wiping area being an area where the wiper wipes the windshield, and the custom wiping mode is a mode in which the wiper wipes a portion of the full wiping area of the windshield;

[0008] The wiper is controlled to perform a wiping operation on the target wiping area.

[0009] In this possible implementation, the wiper's wiping range can be changed, allowing specific areas to be cleaned and erased, allowing the wiper's brushes to specifically clean stains, effectively reducing wear and tear on the brushes and extending their service life. Furthermore, since the steering wheel is closest to the user, a sensor is provided on the steering wheel, allowing the user to determine the target wiping area of the wiper by sliding on the steering wheel sensor, making operation easier and more simple. Furthermore, by determining the target wiping area by sliding the user on the steering wheel sensor, the wiper's wiping range can be controlled more precisely.

[0010] In some embodiments, in response to the operation of sliding the target sliding area on the sensor, determining the target wiping area according to the target sliding area includes:

[0011] When the wiping mode of the wiper is a custom wiping mode, in response to an operation of sliding a target sliding area on the sensor, determining a first wiping area corresponding to the target sliding area;

[0012] Under the condition that a preset curvature constraint is satisfied, determining a position at a preset distance from the boundary of the first wiping area as a soft stop point;

[0013] determining an area between the soft stop point and a boundary of the first wiping area as a second wiping area;

[0014] The target wiping area is determined according to the second wiping area and the first wiping area, and the target wiping area includes the first wiping area and the second wiping area.

[0015] In this possible implementation, the determined target wiping area is larger than the first wiping area, which can ensure that the first wiping area can be completely wiped, so that the wiper's wiper can completely clean the stains in the first wiping area, thereby improving the certainty of cleaning the stains in the first wiping area.

[0016] In some embodiments, the wiper is a wiper with an adjustable wiping area, and in response to an operation of sliding a target sliding area on the sensor, determining a target wiping area according to the target sliding area includes:

[0017] When the wiping mode of the wiper is a custom wiping mode, in response to an operation of sliding a target sliding area on the sensor, the wiping area of the wiper is adjusted from a third wiping area to the target wiping area, wherein the third wiping area is a complete wiping area of the wiper or a partial wiping area different from the target wiping area.

[0018] This possible implementation provides a method for determining the target wiping area in custom mode, which improves the feasibility of this application. Determining the target wiping area through sliding is more convenient and faster than inputting numerical values, improving the speed at which users can adjust the wipers.

[0019] In some embodiments, the wiping area of the wiper is adjusted by adjusting the rotation direction of the drive motor of the wiper, or the wiping area of the wiper is adjusted by adjusting the transmission mechanism of the wiper.

[0020] In this possible implementation, the vehicle controller controls the wipers to perform scraping operations on the target scraping area, which can more specifically remove stains on the windshield and focus on cleaning local stubborn stains. Compared with traditional full-scale scraping, it can more effectively keep the visible area of the windshield clean and tidy, provide the driver with a better field of view, and enhance driving safety.

[0021] In some embodiments, determining the wiping mode of the wiper in response to the first operation on the sensor includes:

[0022] In response to a first operation of pressing the sensor M1 times, the wiping mode of the wiper is determined to be the custom wiping mode, where M1 is an integer greater than or equal to 1.

[0023] In some embodiments, the method further comprises:

[0024] When the wiping mode of the wiper is a target wiping mode, a wiping operation corresponding to the target wiping mode is performed, and the target wiping mode includes a maintenance mode, an automatic wiping mode, an intermittent wiping mode or a high-speed wiping mode. The maintenance mode is a mode for wiping at a preset wiping speed in a preset area, the automatic wiping mode is a mode for automatically adjusting the wiping speed according to the amount of stains, the intermittent wiping mode is a mode for wiping at a preset time interval, and the high-speed wiping mode is a mode for wiping at a maximum wiping speed.

[0025] This possible implementation provides users with a variety of wiper control modes, enhancing the flexibility and adaptability of wiper operation. Users can select different wiper control modes based on different environmental conditions to better cope with various weather conditions, ensuring unimpeded vision. Furthermore, since each user has different wiper usage habits, multiple control modes can meet their individual needs.

[0026] In some embodiments, determining the wiping mode of the wiper in response to the first operation on the sensor includes:

[0027] In response to an operation of pressing M2 times on the sensor, determining that the wiping mode of the wiper is the maintenance mode, where M2 is an integer greater than or equal to 1; or

[0028] In response to a sliding operation on the sensor along a first direction, determining that the wiping mode of the wiper is the automatic wiping mode; or,

[0029] In response to a sliding operation on the sensor along a second direction, determining that the wiping mode of the wiper is the intermittent wiping mode; or,

[0030] In response to a sliding operation on the sensor along a third direction, a wiping mode of the wiper is determined to be the high-speed wiping mode.

[0031] In this possible implementation, the user can directly select the automatic wiping mode, intermittent wiping mode, or high-speed wiping mode through a first operation among the custom mode, maintenance mode, automatic wiping mode, intermittent wiping mode, and high-speed wiping mode. There is no need to first select the normal wiping mode and then select the automatic wiping mode, intermittent wiping mode, or high-speed wiping mode within the normal wiping mode. By directly selecting the wiper wiping mode with a single operation, the user reduces the number of operations required and increases the speed at which the user can select the wiper wiping mode.

[0032] In some embodiments, the target wiping mode includes the automatic wiping mode, the intermittent wiping mode, or the high-speed wiping mode, and determining the wiping mode of the wiper in response to the first operation on the sensor includes:

[0033] In response to an operation of pressing M3 times on the sensor, determining a normal wiping mode, wherein the normal wiping mode includes the automatic wiping mode, the intermittent wiping mode, and the high-speed wiping mode, and M3 is an integer greater than or equal to 1;

[0034] In the normal wiping mode, in response to a sliding operation on the sensor along a first direction, determining that the wiping mode of the wiper is the automatic wiping mode; or

[0035] In the normal wiping mode, in response to a sliding operation on the sensor along a second direction, determining that the wiping mode of the wiper is the intermittent wiping mode; or

[0036] In the normal wiping mode, in response to a sliding operation on the sensor along a third direction, the wiping mode of the wiper is determined to be the high-speed wiping mode.

[0037] In some embodiments, determining the wiping mode of the wiper in response to the first operation on the sensor includes:

[0038] In response to a first operation of pressing the sensor with a pressing pressure greater than a threshold, a wiping mode of the wiper is determined.

[0039] In this possible implementation, by detecting the operating pressure of the first operation, it is possible to accurately distinguish between an accidental touch and an active operation, thereby reducing the false trigger rate and avoiding erroneous operations caused by user's accidental touch.

[0040] In some embodiments, the method further includes: determining a wiping parameter in response to the second operation, the wiping parameter including a wiping area parameter and a wiping speed parameter. Accordingly, controlling the wiper to perform a wiping operation in the wiping mode of the wiper includes: controlling the wiper to perform a wiping operation according to the wiping parameter in the wiping mode of the wiper.

[0041] Another aspect of the present application further provides a wiper control device for use in a vehicle, the vehicle comprising a wiper, a windshield, and a steering wheel, the steering wheel being provided with a sensor, the wiper control device comprising:

[0042] a first determining module, configured to determine a wiping mode of the wiper in response to a first operation on the sensor;

[0043] a second determining module configured to, in response to an operation of sliding a target sliding area on the sensor, determine a target wiping area according to the target sliding area when the wiping mode of the wiper is a custom wiping mode, wherein the target wiping area is an area where the wiper wipes the windshield, and the custom wiping mode is a mode where the wiper wipes a portion of the full wiping area of the windshield;

[0044] The wiping module is used to control the wiper to perform a wiping operation on the target wiping area.

[0045] The computer device provided in the embodiment of the present application includes a memory and a processor. The memory stores a computer program that can be run on the processor. When the processor executes the program, the method of the embodiment of the present application is implemented.

[0046] The computer-readable storage medium provided in the embodiment of the present application stores a computer program thereon, and when the computer program is executed by a processor, the method provided in the embodiment of the present application is implemented.

[0047] The wiper control method, device, computer device, and computer-readable storage medium provided in the embodiments of the present application can improve the flexibility and adaptability of wiper operation by providing users with a choice of wiper control modes, including automatic wiping mode, intermittent wiping mode, high-speed wiping mode, and custom mode. Users can select different wiper control modes according to different environmental conditions. Multiple control modes enable wipers to better cope with various weather conditions, thereby ensuring that vision is not affected. At the same time, since each user has different wiper usage habits, multiple control modes can meet the user's personalized needs. This reduces distractions during driving, allowing drivers to focus more on driving, further improving driving safety, and solving the technical problems raised in the background technology.

[0062] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

[0063] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.

[0064] In the following description, reference is made to “some embodiments”, which describes a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0065] It should be pointed out that the terms "first\second\third" involved in the embodiments of the present application are used to distinguish similar or different objects, and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0066] With the rapid development of intelligent vehicle technology, automotive features continue to innovate, significantly improving performance. As a key component for ensuring a clear driver's field of view and driving safety, the evolution of windshield wiper control methods has attracted considerable attention.

[0067] In traditional car wiper control, when the wiper wipes the stains on the windshield, the wiper will clean and wipe the entire windshield, that is, the wiper needs to complete the entire wiping stroke, resulting in the wiper not only cleaning and wiping the area with stains, but also cleaning and wiping other areas of the windshield without stains. As a result, the wiper assembly has a larger wiping area when wiping stains, causing the wiper to wear out faster and have a shorter service life.

[0068] To this end, an embodiment of the present application provides a wiper control method, which is applied to a vehicle, the vehicle including a wiper, a windshield and a steering wheel, and a sensor is provided on the steering wheel. The method includes: determining a wiping mode of the wiper in response to a first operation on the sensor; when the wiping mode of the wiper is a custom wiping mode, in response to an operation of sliding a target sliding area on the sensor, determining a target wiping area according to the target sliding area, the target wiping area being the area where the wiper wipes the windshield, and the custom wiping mode being a mode in which the wiper wipes a partial area within the complete wiping area of the windshield; controlling the wiper to perform a wiping operation on the target wiping area.

[0069] In this possible implementation, the wiper's wiping range can be changed, allowing specific areas to be cleaned and erased, allowing the wiper's brushes to specifically clean stains, effectively reducing wear and tear on the brushes and improving their service life. Furthermore, since the steering wheel is closest to the user, a sensor is provided on the steering wheel, allowing the user to determine the target wiping area of the wiper by sliding on the steering wheel sensor, making operation easier and more simple. Furthermore, by determining the target wiping area by sliding the user on the steering wheel sensor, the wiper's wiping range can be controlled more precisely.

[0070] The embodiment of the present application is described by taking the wiper control method applied in a vehicle controller as an example, but it does not mean that the embodiment of the present application can only be applied to the wiper control in a vehicle controller.

[0071] The wiper control method provided in the embodiment of the present application is explained in detail below.

[0072] Figure 1 This is a flow chart of a wiper control method provided by the present application. This method can be applied to a vehicle controller, which may include any control unit and / or processor with processing, control, identification, calculation and other functions. Figure 1 , an embodiment of the present application provides a wiper control method, the method comprising:

[0073] 101. In response to a first operation on a sensor, determine a wiping mode of a wiper.

[0074] In response to a first user operation, the vehicle controller determines a wiper mode. The wiper mode can be any one of a custom mode, a maintenance mode, an automatic wiper mode, an intermittent wiper mode, and a high-speed wiper mode. The automatic wiper mode automatically adjusts the wiper speed based on the amount of dirt on the vehicle. For example, the vehicle controller can automatically adjust the wiper speed based on the amount of rain detected by a rain sensor on the vehicle. When the sensor detects an increase in rain on the vehicle's windshield, the wiper automatically speeds up; conversely, when the rain decreases, the wiper speed slows down accordingly. This mode eliminates the need for the driver to frequently manually adjust the wipers, allowing them to focus more on driving, thereby improving driving safety and convenience.

[0075] Intermittent wiping mode wipes at preset intervals. The driver can adjust the intervals, typically from a few seconds to tens of seconds, based on actual conditions. This mode is ideal for light rain, ensuring timely removal of rain from the windshield without obstructing vision or causing excessive wear on the wiper blades due to excessive wiping.

[0076] High-speed wiping mode operates at maximum speed. In high-speed wiping mode, the wipers wipe continuously at their fastest speed. It is typically used in rainstorms or heavy rain to quickly clear large amounts of water from the windshield, ensuring good visibility for the driver.

[0077] This custom mode targets a portion of the wiper's full wiping area. In custom mode, the wipers will wipe within the user-selected area at a user-defined speed and frequency. This allows for focused cleaning in selected areas, effectively improving cleaning results. This also allows for personalized wiper adjustments, enhancing the adaptability and flexibility of wiper control.

[0078] Maintenance mode enables wipers to wipe in a preset area at a preset wiping speed. In maintenance mode, the vehicle controller quickly activates the wipers, causing them to wipe in a single motion pattern within the preset wiping area, ignoring the selected wiping mode and wiping area. This allows for more intuitive observation of the wipers' basic operating conditions, facilitating quick inspection and repair of wipers and locating faults. Furthermore, if other wiping mode-related functions of the vehicle malfunction, such as malfunctions with wiping area selection and / or wiping speed adjustment, maintenance mode can be selected, ignoring the selected wiping mode and wiping area, and allowing for rapid wiping.

[0079] In some embodiments, the maintenance mode is a mode in which both the wiping speed and the wiping area are fixed values.

[0080] 102. When the wiping mode of the wiper is a custom wiping mode, in response to an operation of sliding a target sliding area on a sensor, determine a target wiping area according to the target sliding area.

[0081] When the wiper's wiping mode is a custom wiping mode, in response to an operation of sliding a target sliding area on the sensor, the vehicle controller determines a target wiping area based on the target sliding area. The target wiping area is the area where the wiper wipes the windshield. The custom wiping mode is a mode in which the wiper wipes a partial area within the complete wiping area of the windshield.

[0082] 103. Control the wiper to perform a wiping operation on the target wiping area.

[0083] In Custom mode, the vehicle controller can control the wipers' wiper range within a specific area. In Custom mode, the wipers can wipe within a user-selected area at a user-defined speed and frequency. This allows for focused cleaning in selected areas, effectively improving cleaning results. This also enables personalized wiper adjustments, enhancing the adaptability and flexibility of wiper control.

[0084] The first operation is described in detail below.

[0085] In some embodiments, the above-mentioned first operation may be an operation on the sensor. The first operation may specifically be a sliding operation and / or pressing operation on the sensor, exemplified by two consecutive pressing operations on the sensor, or a clockwise sliding operation on the sensor. In addition, depending on the type of sensor, it may also be other types of operations, exemplified by a click operation on the display screen, etc., which are not specifically limited here.

[0086] Exemplarily, the first operation may be an operation performed by a user on any device of the vehicle that can interact with the user. For example, the first operation may be an operation on a display screen in the vehicle, an operation on a steering wheel, an operation on a sensor, and the like.

[0087] In some embodiments, when the pressure of the first operation on the sensor exceeds a threshold, the vehicle controller controls the wipers to perform a wiping operation. That is, after receiving the first operation, the vehicle controller also needs to determine whether the pressure of the first operation exceeds a threshold. Only when the pressure of the first operation exceeds the threshold will the vehicle controller determine the corresponding wiping mode of the wipers based on the first operation.

[0088] Exemplarily, the first operation is a sliding operation on the sensor along a first direction. When the pressing pressure of the sliding operation on the sensor is greater than 3N, the vehicle controller can determine that the corresponding automatic wiping mode is the wiping mode of the wiper; otherwise, even if the user performs a sliding operation on the sensor, the vehicle controller will not determine that the automatic wiping mode is the wiping mode of the wiper.

[0089] It is understood that the requirement that the vehicle controller only determine the corresponding wiper wiping mode when the pressure exerted by the first operation on the sensor exceeds a threshold is a limiting condition imposed to prevent false triggering. Other limitations may also be imposed on the first operation. For example, the vehicle controller may only determine the corresponding wiper wiping mode based on the first operation when the operating time of the first operation exceeds a threshold. This is not specifically limited here.

[0090] It can be understood that in the embodiment of the present application, the first operation can be limited to prevent accidental touches, and the corresponding steps will only be executed when the preset conditions are met; in addition, the same anti-accidental touch limitations can also be applied to other operations. For example, the operation of sliding the target sliding area on the sensor in step 102 can be limited to prevent accidental touches.

[0091] For example, in custom mode, a sliding operation is required on the sensor to determine the corresponding target wiping area. When the pressing pressure of the sliding operation on the sensor is greater than 3N, the vehicle controller will control the wiper to perform the wiping operation on the target wiping area; otherwise, even if the user performs a sliding operation on the sensor, the vehicle controller will not control the wiper to perform the wiping operation on the target wiping area.

[0092] It is understood that the requirement that the vehicle controller only control the wipers to perform a wiping operation based on a sliding operation when the pressure exerted on the sensor by the sliding operation exceeds a threshold is a condition imposed to prevent false triggering. Other conditions may also be imposed on the sliding operation. For example, the vehicle controller may only control the wipers to perform a wiping operation based on a sliding operation when the sliding operation duration exceeds a threshold. These conditions are not specifically defined here.

[0093] In this possible implementation, by detecting the operating pressure of the first operation, it is possible to accurately distinguish between false touches and active operations, reduce the false trigger rate, avoid erroneous operations caused by false touches by users, and improve the safety of users when driving the vehicle.

[0094] In some embodiments, determining the wiping mode of the wiper in response to the first operation on the sensor includes:

[0095] In response to a first operation of pressing the sensor M1 times, it is determined that the wiping mode of the wiper is the custom wiping mode, where M1 is an integer greater than or equal to 1.

[0096] In the embodiment of the present application, the first operation that can be used to determine that the wiper's wiping mode is a custom wiping mode can be an M1 pressing operation, or other times of pressing operations, or one sliding operation, or multiple sliding operations, which are not limited here.

[0097] In some embodiments, in custom mode, the percentage of the target wiping area within the complete wiping area of the wiper corresponds to the percentage of the target sliding area within the complete sliding area of the sensor. After the user slides within the target sliding area on the sensor, the vehicle controller can determine the percentage and position interval of the target sliding area within the complete sliding area of the sensor, and then determine the target wiping area of the target sliding area within the complete wiping area of the wiper based on the percentage and position interval.

[0098] For example, Figure 2 As shown, the sensor's complete sliding area is digitized as 0 to 90 degrees, and the wiper's complete wiping area is digitized as 0° to 90°. The user swipes within the sensor's complete sliding area, from 30° to 60°. This area 30 to 60° becomes the target sliding area. Correspondingly, the target wiping area corresponding to this target sliding area is the 30° to 60° area. In other words, the relationship between the target sliding area L1, the sensor's complete sliding area L2, the target wiping area S1, and the wiper's complete wiping area S2 is: L1 / L2 = S1 / S2.

[0099] For example, Figure 2 As shown in FIG. 1 , the user slides in the area 30 to 60 degrees on the complete sliding area of the sensor. The area 30 to 60 degrees is the target sliding area. Correspondingly, the target wiping area corresponding to the target sliding area is the sector area C1-O-D1, that is, the area 30° to 60°.

[0100] In some embodiments, in response to the operation of sliding the target sliding area on the sensor, determining the target wiping area according to the target sliding area may include:

[0101] Determine a first wiping area corresponding to a target sliding area; determine a position at a preset distance from the boundary of the first wiping area as a soft stop point while satisfying a preset curvature constraint; determine an area between the soft stop point and the boundary of the first wiping area as a second wiping area; and determine a target wiping area based on the second wiping area and the first wiping area, the target wiping area including the first wiping area and the second wiping area.

[0102] In order to ensure that the target wiping area can be completely wiped, the determined target wiping area can be larger than the first wiping area indicated by the user through the sliding operation. Figure 2 As shown in FIG, the complete sliding area of the sensor is digitized as 0 to 90, and the complete wiping area of the wiper is digitized as 0° to 90°. The user slides in the area 30 to 60 on the complete sliding area of the sensor. The area 30 to 60 is the target sliding area. Correspondingly, the first wiping area corresponding to the target sliding area is the area 30° to 60°, i.e. Figure 2 The sector area C1-O-D1 in.

[0103] Then, in order to ensure that the first wiping area corresponding to the target sliding area can be completely wiped, the position at a preset distance from the boundary of the first wiping area can be determined as the soft stop point. The boundary of the first wiping area is the position of 30° and the position of 60°. The preset distance is 2°, and the determined soft stop points are the position of 28° and the position of 28°. The corresponding second area includes the area from 28° to 30° and the area from 60° to 62°, that is, Figure 2 The sector area C2-O-C1 and the sector area D1-O-D2.

[0104] Then, according to the second wiping area of 28° to 30° and the area of 60° to 62°, and the area of 30° to 60° of the first wiping area, the target wiping area is determined to be the area of 28° to 62°, that is, Figure 2 The sector area C2-O-D2 in the target wiping area includes a first wiping area and a second wiping area.

[0105] In some embodiments, the wiper is a wiper with an adjustable wiping area. In response to an operation of sliding a target sliding area on a sensor, determining a target wiping area according to the target sliding area includes:

[0106] When the wiping mode of the wiper is a custom wiping mode, in response to an operation of sliding a target sliding area on the sensor, the vehicle controller adjusts the wiping area of the wiper from a third wiping area to the target wiping area, where the third wiping area is a complete wiping area of the wiper or a partial wiping area different from the target wiping area.

[0107] It can be understood that the custom wiping mode in the embodiment of the present application is a wiping mode in which the wiping area can be adjusted, so the wiping area of the wiper can be adjusted from the third wiping area to the target wiping area in response to the operation on the sensor.

[0108] In some embodiments, the wiping area of the wiper is adjusted by adjusting the rotation direction of the drive motor of the wiper, or the wiping area of the wiper is adjusted by adjusting the transmission mechanism of the wiper.

[0109] In some embodiments, the wipers on a vehicle are driven by a motor that continuously rotates 360° via a crank-rocker mechanism. The crank is mounted on the wiper motor shaft. When the wiper motor makes 360° motion, the crank on the output shaft drives the wiper blade to swing back and forth, sweeping a sector-shaped area on the windshield. In a custom mode, to achieve focused wiping of a target wiping area, the vehicle controller can reverse the wiper motor when the wiper reaches one edge of the target wiping area, steering the wiper in the opposite direction. When the wiper reaches the other edge of the target wiping area, the controller controls the wiper motor to reverse again, effectively adjusting the wiper's wiping range to the target wiping area through control of the wiper motor. This reciprocating cycle achieves wiping of the target wiping area.

[0110] For example, Figure 2 As shown, the starting position of the wiper is at OA. For the target wiping area of the sector area C2-O-D2, the vehicle controller can control the wiper motor to rotate forward first, and then the wiper Figure 2 After wiping from the AO position to the D2O position, that is, reaching one edge of the target wiping area, the vehicle controller can then control the wiper motor to rotate in the opposite direction. Correspondingly, the wiper starts to rotate from the D2O position to the C2O position. After the wiper reaches the C2O position, that is, reaching the other edge of the target wiping area, the vehicle controller controls the wiper motor to rotate forward again and repeats the cycle, thereby achieving wiping of the target wiping area.

[0111] In some embodiments, the wiper is a wiper with an adjustable wiping area, for example, Figure 3As shown, the wiper assembly 300 includes a crank 301, an adjustment device 302, a connecting rod 303, a wiper 304, a wiper motor 305 for driving the wiper for wiping, and an adjustment motor 306 for adjusting the crank's length. The crank 301 can be extended and retracted along its extension direction by the adjustment motor 306 in the adjustment device 302. The connecting rod 303 connects the crank 301 and the wiper 304. The drive of the wiper motor 305 causes the crank 301 to move the connecting rod 303, which in turn drives the wiper 304 to rotate about point A in the figure, thereby cleaning and erasing the windshield and preventing stains on the windshield that could obstruct the driver's field of view.

[0112] In this embodiment, the crank 301 is capable of extending and retracting along its extension direction, thereby changing the rotation radius of the crank 301. Thus, by changing the rotation radius of the crank 301, the wiping area of the wiper 304 can be changed through the transmission of the connecting rod 303, thereby cleaning and erasing the target wiping area. This allows the wiper 304 to clean stains in a targeted manner, effectively reducing brush wear and improving the service life of the brush. An adjustment device 302 is provided on the crank 301 and is used to drive the crank 301 to extend and retract. This allows the driver to control the extension and retraction of the crank 301 by controlling the extension and retraction drive member, thereby improving the extension and retraction accuracy of the crank 301 and enabling more precise control of the wiping area of the wiper 304.

[0113] In some embodiments, the wiper is a wiper with adjustable wiping area. In the custom mode, the adjustment device 302 can be controlled to adjust the rotation radius of the crank 301, thereby changing the wiping area of the wiper 304. For example, Figure 3 As shown, by turning the crank 301 from Figure 3 The middle point F1 is adjusted to the point F2, and the corresponding wiping area of the wiper is adjusted from the sector-shaped area AOB to the sector-shaped area COD, and the sector-shaped area COD includes the target wiping area, thereby achieving wiping of the target wiping area.

[0114] It is worth noting that in custom mode, in response to the operation of sliding the target sliding area on the sensor, the vehicle controller controls the wiper to perform a wiping operation on the target wiping area, which can remove stains on the windshield more specifically, and focus on cleaning local stubborn stains. Compared with traditional full-scale wiping, it can more effectively keep the visible area of the windshield clean and tidy, provide the driver with a better field of vision, and enhance driving safety; at the same time, the wiper only works in the stained area, reducing unnecessary friction and contact with the windshield, thereby reducing the wear rate of the wiper strips, extending the service life of the wiper, and saving the cost and frequency of replacing wipers.

[0115] In some embodiments, part of the sensor area is a sliding area, and part of the sensor area is a pressing area. Figure 4 As shown, Figure 4 The sensor includes a first area, a second area, and a third area, wherein the first area and the second area are areas that can be pressed, and the third area is an area that can be slid. In addition, the sensor in this application can also be a sensor in which the entire area can be slid and part of the area can be pressed; it can also be a sensor in which the entire area can be pressed and part of the area can be slid; it can also be a sensor in which the entire area can be both slid and pressed; the specifics are not limited here.

[0116] In some embodiments, as Figure 5 As shown, the above-mentioned sensors can be located on the vehicle in the central area 501, the left outer ring grip area 502, the right outer ring grip area 503, the left control area 504 and the right control area 505 on the steering wheel. In addition, they can also be located in other areas, which are not limited here.

[0117] In this possible implementation, placing the sensor on the vehicle's steering wheel can shorten the operation path and improve driving safety and convenience, as follows:

[0118] 1. Reduce driving distractions and improve driving safety.

[0119] Drivers can control the windshield wipers using sensors on the steering wheel without taking their eyes off the road or their hands off the steering wheel. While traditional center console buttons or in-car screens require the driver to turn their head or reach out to operate them, the steering wheel buttons are located within natural handholding (such as around the 3 o'clock and 9 o'clock areas). Operation requires only a light touch or slight movement of the finger, without the driver needing to look away from the road ahead. This eliminates the risk of accidents caused by distraction, such as taking one hand off the steering wheel or looking down at a screen.

[0120] 2. Optimize operational efficiency and enhance driving experience.

[0121] Setting the sensor on the vehicle's steering wheel is friendly to the driver's blind operation and reduces cognitive load. Setting the sensor on the vehicle's steering wheel in a fixed and ergonomic position (such as the area accessible by the thumb and index finger) allows the driver to complete the operation through muscle memory without visually pressing buttons or thinking about the operating logic. It is especially suitable for quick response in complex road conditions.

[0122] In some embodiments, the wiper's wiping mode is a maintenance mode, and in response to a press on a sensor, the wiper is controlled to perform a wiping operation. For example, in maintenance mode, in response to two consecutive presses on the sensor, the wiper is controlled to perform a wiping operation. In addition, in maintenance mode, other operations can also be used to trigger the vehicle controller to control the wiper to perform a wiping operation, the specific details of which are not limited here.

[0123] In some embodiments, after determining the wiper wiping mode through a first operation, the vehicle controller directly controls the wipers to perform a wiping operation in the wiper wiping mode without performing the second operation. For example, after determining the service mode as the wiper wiping mode through the first operation, the vehicle controller directly controls the wipers to wipe at a preset speed within a preset area.

[0124] In this possible implementation, the user does not need to perform the second operation to trigger the wiping operation, which reduces the driver's operating burden and improves the response speed of the wiper system.

[0125] In some embodiments, the vehicle further comprises a steering wheel, and the above-mentioned sensor is arranged on the steering wheel. Figure 5 As shown, the sensor can be placed along the circumference of the steering wheel. When driving a vehicle, the driver usually places their hands at the 3 o'clock and 9 o'clock positions on the steering wheel (i.e., the leftmost and rightmost edges of the steering wheel), which makes it easier for the driver to control the vehicle. In addition, the sensor can also be placed in other positions on the steering wheel, such as the center of the steering wheel, etc., and the specific position is not limited here.

[0126] It is worth mentioning that the sensor for controlling the wipers is set on the steering wheel. The driver can easily control the wipers without taking his hands off the steering wheel, which allows the driver to react faster. When encountering sudden rain or needing to quickly clear rain from the windshield, the wipers can be quickly started or adjusted. The working mode of the wipers can be adjusted in time according to the rainfall conditions without distracting the driver's attention, thereby improving the line of sight in time and improving driving safety.

[0127] In some embodiments, when the wiping mode of the wiper is a target wiping mode, the wiping operation corresponding to the target wiping mode is performed. The target wiping mode includes a maintenance mode, an automatic wiping mode, an intermittent wiping mode or a high-speed wiping mode. The maintenance mode is a mode for wiping at a preset wiping speed in a preset area. The automatic wiping mode is a mode for automatically adjusting the wiping speed according to the amount of dirt. The intermittent wiping mode is a mode for wiping at a preset time interval. The high-speed wiping mode is a mode for wiping at the maximum wiping speed.

[0128] For example, in the aforementioned automatic wiping mode, the vehicle controller can automatically adjust the wiper speed based on the amount of dirt on the vehicle. For example, the vehicle controller can automatically adjust the wiper speed based on the amount of rain detected by the vehicle's rain sensor. When the sensor detects an increase in rain on the vehicle's windshield, the wipers automatically increase their wiping speed; conversely, when the rain decreases, the wiping speed decreases accordingly. This mode eliminates the need for drivers to frequently manually adjust the wipers, allowing them to focus more on driving, improving driving safety and convenience.

[0129] In this intermittent wiping mode, the vehicle controller controls the wipers to wipe at preset intervals. The driver can adjust the intervals based on actual conditions, typically ranging from a few seconds to tens of seconds. This mode is ideal for light rain, ensuring timely removal of rain from the windshield without obstructing vision or causing excessive wear on the wiper blades due to excessive wiping.

[0130] In the high-speed wiping mode, the vehicle controller can control the wipers to wipe at the maximum wiping speed, and the wipers will wipe continuously at the fastest speed. It is usually used in rainstorms or heavy rain to quickly clear a large amount of water from the windshield and ensure the driver has a good view.

[0131] In this maintenance mode, the vehicle controller can quickly activate the wipers, causing them to wipe in a fixed wiping area according to a single action pattern, regardless of the selected wiping mode and wiping area. This allows for a more intuitive observation of the wipers' basic operating conditions, facilitating quick inspection and maintenance of the wipers and locating faults.

[0132] It's worth noting that by offering users a choice of wiper control modes, including automatic wiping, intermittent wiping, high-speed wiping, and custom modes, the flexibility and adaptability of wiper operation can be enhanced. Users can select different wiper control modes based on different environmental conditions. For example, different rainfall intensities require different wiper speeds to keep the windshield clear. Light rain can use the low-speed intermittent mode, heavy rain requires the high-speed continuous mode, and torrential rain may require even faster speeds or additional enhanced modes. Multiple control modes allow wipers to better cope with various weather conditions, ensuring unimpeded visibility.

[0133] Since each user has different wiper habits, multiple control modes can meet their individual needs. Some prefer longer wiper intervals, while others prefer the wipers to stop at different positions after each wipe. Through custom modes, users can set them according to their preferences, increasing driving comfort. This reduces distractions while driving, allowing drivers to focus more on the road and further improving driving safety.

[0134] Furthermore, choosing the right wiper control mode can reduce unnecessary wear and tear on wipers and their motors. For example, in light or intermittent rain, using intermittent mode can prevent the wipers from operating continuously for extended periods, reducing the frequency of friction between the wiper blades and the windshield, thereby extending the wiper's lifespan and saving replacement costs.

[0135] In some embodiments, the first operation may include multiple operation steps, the target wiping mode includes an automatic wiping mode, an intermittent wiping mode, or a high-speed wiping mode, and determining the wiping mode of the wiper in response to the first operation on the sensor includes:

[0136] In response to an operation of pressing the sensor M3 times, a normal wiping mode is determined, where the normal wiping mode includes an automatic wiping mode, an intermittent wiping mode, and a high-speed wiping mode, and M3 is an integer greater than or equal to 1;

[0137] In the normal wiping mode, in response to a sliding operation on the sensor along a first direction, determining that the wiping mode of the wiper is the automatic wiping mode; or

[0138] In the normal wiping mode, in response to a sliding operation on the sensor along the second direction, determining that the wiping mode of the wiper is the intermittent wiping mode; or,

[0139] In the normal wiping mode, in response to a sliding operation on the sensor along a third direction, the wiping mode of the wiper is determined to be the high-speed wiping mode.

[0140] For example, Figure 6 As shown:

[0141] 601 . In response to operation B1 , determine a normal wiping mode.

[0142] like Figure 7 As shown, in response to operation B1, the vehicle controller determines a normal wiping mode among multiple control modes, which may include a custom mode, a maintenance mode, and a normal wiping mode. That is, in response to the first operation, the vehicle controller determines the normal wiping mode among the custom mode, the maintenance mode, and the normal wiping mode. The normal wiping mode includes an automatic wiping mode, an intermittent wiping mode, and a high-speed wiping mode.

[0143] Exemplarily, the vehicle controller determines the normal wiping mode among the custom mode, maintenance mode and normal wiping mode in response to M3 consecutive pressing operations on the sensor (ie, the above-mentioned operation B1), where the normal wiping mode includes the automatic wiping mode, the intermittent wiping mode and the high-speed wiping mode.

[0144] 602 : In response to operation B2 , determine a wiping mode of the wiper in the normal wiping mode.

[0145] like Figure 7 As shown, the vehicle controller then determines, in response to operation B2 , one of the automatic wiping mode, the intermittent wiping mode, and the high-speed wiping mode included in the normal wiping mode as the wiping mode of the wiper.

[0146] It is understood that, in this application, the first operation refers to all operations for selecting a wiper control mode. In this embodiment, the first operation may include multiple operation steps. For example, the first operation may include the above-mentioned operation B1 and operation B2.2, or the above-mentioned operation B1 and operation B2.3, or the above-mentioned operation B1 and operation B2.1. In addition, other specific operations for determining the wiper wiping mode may also be included, which are not limited here.

[0147] For example, Figure 7 As shown, the vehicle controller can determine the high-speed wiping mode as the wiping mode of the wiper in the normal wiping mode in response to operation B2.1; or, the vehicle controller can determine the automatic wiping mode as the wiping mode of the wiper in the normal wiping mode in response to operation B2.2; or, the vehicle controller can determine the intermittent wiping mode as the wiping mode of the wiper in the normal wiping mode in response to operation B2.3.

[0148] It can be understood that the above operation B2 may include any one of the above operations B2.1, B2.2 and B2.3.

[0149] For example, the vehicle controller may determine that the automatic wiping mode is the wiping mode of the wiper in response to a sliding operation on the sensor along a first direction (i.e., operation B2.2); or, the vehicle controller may determine that the intermittent wiping mode is the wiping mode of the wiper in response to a sliding operation on the sensor along a second direction (i.e., operation B2.23); or, the vehicle controller may determine that the high-speed wiping mode is the wiping mode of the wiper in response to a sliding operation on the sensor along a third direction (i.e., operation B2.1).

[0150] For example, the vehicle controller may determine the wiper's wiping mode as intermittent wiping in response to a clockwise sliding operation on the sensor; determine the wiper's wiping mode as automatic wiping in response to a counterclockwise sliding operation on the sensor; and determine the wiper's wiping mode as high-speed wiping in response to a clockwise and then counterclockwise sliding operation on the sensor. Other operations may also be included, corresponding to other wiper control modes, which are not specifically limited here.

[0151] It is understandable that, since the normal control mode includes the automatic wiping mode, the intermittent wiping mode and the high-speed wiping mode, it is necessary to further determine the wiping mode.

[0152] In some embodiments, as Figure 7 As shown, the vehicle controller may also determine the corresponding wiper control mode as the wiper mode in response to other operations. For example, the vehicle controller may determine the service mode as the wiper mode in response to operation A. Alternatively, the vehicle controller may determine the custom mode as the wiper mode in response to operation C.

[0153] In some embodiments, as Figure 7 As shown, the corresponding relationship between the specific operation of the first operation and the wiper control mode can be shown in the following Table 1:

[0154] Table 1

[0155]

[0156] In some embodiments, the normal control mode includes an automatic scraping mode, an intermittent scraping mode, and a high-speed scraping mode. In addition, other control modes may also be included, which are not specifically limited here.

[0157] When determining the wiping mode of the wiper, the wiping mode of the wiper can be determined through multiple steps, that is, the first operation can include multiple specific operation steps. In addition, the first operation can also have only one specific operation step, which is described in detail below:

[0158] In some embodiments, the first operation may include only one operation step. The determining of the wiping mode of the wiper in response to the first operation on the sensor includes:

[0159] In response to an operation of pressing the sensor M2 times, determining that the wiper mode is the maintenance mode, where M2 is an integer greater than or equal to 1; or,

[0160] In response to a sliding operation on the sensor along a first direction, determining that a wiping mode of the wiper is an automatic wiping mode;

[0161] or,

[0162] In response to a sliding operation on the sensor along a second direction, determining that the wiping mode of the wiper is an intermittent wiping mode;

[0163] or,

[0164] In response to the sliding operation of the sensor in the third direction, it is determined that the wiping mode of the wiper is the high-speed wiping mode.

[0165] For example, Figure 8As shown, the vehicle controller determines that the maintenance mode is the wiper mode in response to operation A. For example, in response to M2 consecutive presses on the sensor, for example, four consecutive presses on the sensor, the vehicle controller may determine that the maintenance mode is the wiper mode.

[0166] or,

[0167] The vehicle controller determines the high-speed wiping mode as the wiping mode of the wipers in response to operation B. For example, in response to a sliding operation on the sensor in a third direction, for example, first sliding the sensor in a clockwise direction and then in a counterclockwise direction, the vehicle controller determines the high-speed wiping mode as the wiping mode of the wipers.

[0168] or,

[0169] The vehicle controller determines the automatic mode as the wiper mode in response to operation C. For example, in response to a sliding operation on the sensor in a first direction, for example, a sliding operation on the sensor in a counterclockwise direction, the vehicle controller determines the automatic wiper mode as the wiper mode; or

[0170] The vehicle controller determines the intermittent wiping mode as the wiping mode of the wiper in response to operation D. For example, in response to a sliding operation on the sensor in the second direction, for example, a sliding operation on the sensor in the clockwise direction, the vehicle controller determines the intermittent wiping mode as the wiping mode of the wiper; or

[0171] The vehicle controller determines the custom mode as the wiper mode in response to operation E. For example, in response to pressing the sensor M1 times in succession, for example, three times in succession, the vehicle controller determines the custom mode as the wiper mode.

[0172] In addition, the vehicle controller can also determine other corresponding wiper control modes in response to other types of operations, which are not specifically limited here.

[0173] It can be understood that in the present application, the first operation indicates all operations for selecting the wiper control mode, so the first operation may include at least one specific operation step, which can be, for example, any one of the above-mentioned operations A, B, C, D and E. In addition, it can also include other specific operations for determining the wiping mode of the wiper, which is not limited here.

[0174] For example, the correspondence between the specific operation of the first operation and the wiper control mode may be shown in Table 2 below:

[0175] Table 2

[0176]

[0177] In this possible implementation, the user can directly select the automatic wiping mode, intermittent wiping mode, or high-speed wiping mode through a first operation among the custom mode, maintenance mode, automatic wiping mode, intermittent wiping mode, and high-speed wiping mode. There is no need to first select the normal wiping mode and then select the automatic wiping mode, intermittent wiping mode, or high-speed wiping mode within the normal wiping mode. By directly selecting the wiper wiping mode with a single operation, the user reduces the number of operations required and increases the speed at which the user can select the wiper wiping mode.

[0178] In some embodiments, after determining the wiping mode of the wiper, a second operation is required to determine the corresponding wiping parameters before the vehicle controller controls the wiper to perform the wiping operation. The second operation triggers the wiper to perform the wiping operation in the wiping mode of the wiper.

[0179] In some embodiments, the second operation may be used to instruct determination of wiping parameters in the wiping mode of the wiper, specifically, Figure 9 As shown:

[0180] 901. In response to a first operation, determine a wiping mode of a wiper.

[0181] Step 901 is the same as the specific implementation method of determining the wiper mode described above, and will not be repeated here.

[0182] 902. In response to the second operation, determine a wiping parameter.

[0183] After determining the wiping mode of the wiper, in response to the second operation, the vehicle controller determines the wiping parameters under the wiping mode of the wiper, the wiping parameters including a wiping area parameter and a wiping speed parameter, the wiping area parameter being used to indicate the area in which wiping is performed, and the wiping speed parameter being used to indicate the speed at which wiping is performed.

[0184] For example, the second operation may be a sliding operation on the target area on the sensor, and in response to the sliding operation, the vehicle controller may determine the corresponding target wiping area parameter.

[0185] For example, the second operation can be a different number of presses on the sensor. In high-speed wiping mode, in response to M4 presses on the sensor, the vehicle controller can determine the wiping speed parameter corresponding to the high-speed wiping mode. For example, in custom mode, two presses correspond to increasing the wiping speed by 1, and three presses correspond to decreasing the wiping speed by 1. If the initial wiping speed is 5, in response to two presses on the sensor, the vehicle controller updates the wiping speed to 6.

[0186] For example, the second operation may be a pressing operation on different areas of the sensor, where the pressing operation on different areas indicates an increase or decrease in the scraping speed parameter. Figure 4 As shown, the sensor may include a first area and a second area. A press operation on the first area may instruct the wiping speed to be increased by 1, and a press operation on the second area may instruct the wiping speed to be decreased by 1. When the initial wiping speed is 5, in response to the press operation on the first area, the vehicle controller updates the wiping speed to 6. When the initial wiping speed is 5, in response to the press operation on the second area, the vehicle controller updates the wiping speed to 4.

[0187] It is understood that in the embodiment of the present application, after the wiping mode of the wiper is determined in response to the first operation, the wiping parameters of the determined wiping mode can be adjusted in response to the second operation. Among the multiple wiping modes of the wiper, at least one wiping mode supports adjustable wiping parameters.

[0188] 903. In the wiping mode of the wiper, control the wiper to perform a corresponding wiping operation according to the wiping parameters.

[0189] In the wiping mode of the wiper, the vehicle controller controls the wiper to perform a wiping action in the target wiping area indicated by the wiping parameter and at a wiping speed indicated by the wiping parameter.

[0190] For example, the wiping speed indicated by the above wiping parameters is 5, and the indicated wiping area is the target wiping area in the complete wiping area. In response to the second operation, the vehicle controller can control the wiper to perform a wiping action at a wiping speed of 5 in the target wiping area.

[0191] In some embodiments, since the second operation indicates all operations that trigger the wiper to perform wiping in the wiping mode of the wiper, the second operation may include at least one specific operation step. For example, the corresponding wiping area can be determined by the second operation 1, and the corresponding wiping speed can be determined by the second operation 2. In addition, other operations may also be included, which are not limited here.

[0192] In this possible implementation, the wiping parameters in the wiping mode of the wiper can also be adjusted through the second operation, providing the user with more flexible wiper control options and achieving more precise wiper control.

[0193] In some embodiments, as Figure 10 As shown, the wiper control method in this application may specifically include the following steps:

[0194] 1001. In response to a first operation, determine a wiping mode of a wiper.

[0195] In response to a first operation by a user, the vehicle controller determines a wiper wiping mode corresponding to the first operation, wherein the wiper wiping mode may be any one of a custom mode, a maintenance mode, an automatic wiping mode, an intermittent wiping mode, and a high-speed wiping mode.

[0196] For example, Figure 10 As shown, the vehicle controller may determine, in response to operation A, that the service mode is the wiper wiping mode. Alternatively, in response to operation B, the vehicle controller may determine, in response to operation C, that the automatic mode is the wiper wiping mode. Alternatively, in response to operation D, the vehicle controller may determine, in response to operation E, that the intermittent wiping mode is the wiper wiping mode. The specific determination method can be found in the previous description and will not be repeated here.

[0197] 1002. Determine whether the pressing pressure of the first operation is greater than a threshold.

[0198] The vehicle controller determines whether the pressing pressure during the first operation is greater than a threshold. If the pressing pressure during the first operation is greater than the preset threshold, the vehicle controller executes subsequent steps. If the pressing pressure during the first operation is not greater than the preset threshold, the vehicle controller does not execute subsequent steps. The specific determination method can be referred to the above description and will not be repeated here.

[0199] For example Figure 10 As shown, the vehicle controller can determine whether the pressing pressure of operation A is greater than the threshold. If it is, the subsequent steps are executed. If it is not, the vehicle controller does not execute the subsequent steps. The pressing pressure detection corresponding to other operations is also the same and will not be repeated here.

[0200] 1003. In response to the second operation, determine wiping parameters.

[0201] When the pressing pressure of the first operation is greater than a threshold, in response to the second operation, the vehicle controller determines the wiping parameters in the wiping mode of the wiper, and the wiping parameters include a wiping area parameter and a wiping speed parameter. The wiping area parameter is used to indicate the area where wiping is performed, and the wiping speed parameter is used to indicate the speed at which wiping is performed.

[0202] For example, Figure 10 As shown, in the custom mode, the vehicle controller can determine the corresponding target wiping area in response to F. The specific determination method can be referred to the above description and will not be repeated here.

[0203] 1004. Determine whether the pressing pressure of the second operation is greater than a threshold.

[0204] The vehicle controller determines whether the pressing pressure of the second operation is greater than a threshold. If the pressing pressure of the second operation is greater than the preset threshold, the subsequent steps are executed. If the pressing pressure of the second operation is not greater than the preset threshold, the vehicle controller does not execute the subsequent steps. The specific determination method can be referred to the above description and will not be repeated here.

[0205] 1005. In the wiping mode of the wiper, control the wiper to perform a corresponding wiping operation according to the wiping parameters.

[0206] When the pressing pressure of the second operation is greater than the threshold, in the wiping mode of the wiper, the vehicle controller controls the wiper to perform a wiping action in the target wiping area indicated by the wiping parameter and at a wiping speed indicated by the wiping parameter.

[0207] In addition, there may be other implementations, for example, in some embodiments, Figure 11 As shown, the wiper control method in this application may specifically include the following steps:

[0208] 1101. In response to operation B1, determine the normal wiping mode.

[0209] In response to operation B1, the vehicle controller determines a normal wiping mode from among multiple control modes, where the multiple control modes may include a custom mode, a service mode, and a normal wiping mode. That is, in response to the first operation, the vehicle controller determines the normal wiping mode from among the custom mode, the service mode, and the normal wiping mode. The normal wiping mode includes an automatic wiping mode, an intermittent wiping mode, and a high-speed wiping mode.

[0210] 1102. Determine whether the pressing pressure of operation B1 is greater than a threshold.

[0211] The vehicle controller determines whether the pressing pressure during operation B1 is greater than a threshold. If the pressing pressure during operation B1 is greater than the preset threshold, the vehicle controller executes the subsequent steps. If the pressing pressure during operation B1 is not greater than the preset threshold, the vehicle controller does not execute the subsequent steps. The specific determination method can be found in the previous description and will not be repeated here.

[0212] 1103. In response to operation B2, determine a wiping mode of the wiper in the normal wiping mode.

[0213] In response to operation B2 , the vehicle controller determines one of the automatic wiping mode, the intermittent wiping mode, and the high-speed wiping mode included in the normal wiping mode as the wiping mode of the wiper.

[0214] For example, Figure 11As shown, the vehicle controller can determine the high-speed wiping mode as the wiping mode of the wiper in the normal wiping mode in response to operation B2.1; or, the vehicle controller can determine the automatic wiping mode as the wiping mode of the wiper in the normal wiping mode in response to operation B2.2; or, the vehicle controller can determine the intermittent wiping mode as the wiping mode of the wiper in the normal wiping mode in response to operation B2.3.

[0215] It can be understood that the above operation B2 may include any one of the above operations B2.1, B2.2 and B2.3.

[0216] 1104. Determine whether the pressing pressure of operation B2 is greater than a threshold.

[0217] The vehicle controller determines whether the pressing pressure during operation B2 exceeds a threshold. If the pressing pressure during the first operation exceeds the preset threshold, the vehicle controller executes the subsequent steps. If the pressing pressure during the first operation does not exceed the preset threshold, the vehicle controller does not execute the subsequent steps. The specific determination method can be found in the previous description and will not be repeated here.

[0218] 1105. In response to the second operation, determine wiping parameters.

[0219] When the pressing pressure of the first operation is greater than a threshold, in response to the second operation, the vehicle controller determines the wiping parameters in the wiping mode of the wiper, and the wiping parameters include a wiping area parameter and a wiping speed parameter. The wiping area parameter is used to indicate the area where wiping is performed, and the wiping speed parameter is used to indicate the speed at which wiping is performed.

[0220] For example, Figure 10 As shown, in the custom mode, the vehicle controller can determine the corresponding target wiping area in response to operation D. The specific determination method can be referred to the above description and will not be repeated here.

[0221] 1106. Determine whether the pressing pressure of the second operation is greater than a threshold.

[0222] The vehicle controller determines whether the pressing pressure of the second operation is greater than a threshold. If the pressing pressure of the second operation is greater than the preset threshold, the subsequent steps are executed. If the pressing pressure of the second operation is not greater than the preset threshold, the vehicle controller does not execute the subsequent steps. The specific determination method can be referred to the above description and will not be repeated here.

[0223] 1107. In the wiping mode of the wiper, control the wiper to perform a corresponding wiping operation according to the wiping parameters.

[0224] When the pressing pressure of the second operation is greater than the threshold, in the wiping mode of the wiper, the vehicle controller controls the wiper to perform a wiping action in the target wiping area indicated by the wiping parameter and at a wiping speed indicated by the wiping parameter.

[0225] The vehicle controller may include, but is not limited to, an onboard terminal, an electronic control device, a body control device, etc. The functions implemented by this method can be implemented by a processor in the vehicle controller calling program code. Of course, the program code can also be stored in a computer storage medium. Therefore, the vehicle controller includes at least a processor and a storage medium.

[0226] It should be understood that, although the steps in the above-mentioned flowcharts are shown in sequence as indicated by the arrows, these steps are not necessarily performed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be performed in other orders.
