Description

Technical Field

[0001] This application relates to the field of vehicle control technology, and includes, but is not limited to, a windshield wiper control method, device, equipment, and storage medium. Background Technology

[0002] With the rapid development of intelligent vehicle technology, automobiles are constantly innovating their functions and significantly improving their performance. As a key component that ensures clear visibility for drivers and guarantees driving safety, the evolution of windshield wipers' control methods has attracted much attention.

[0003] Traditional car windshield wiper controls involve the wipers cleaning the entire windshield surface when wiping away dirt. This means the wipers need to complete the entire wiping stroke, cleaning not only stained areas but also other clean areas of the windshield. This results in a larger wiping area for the wiper assembly when cleaning dirt, leading to faster wear and tear and a shorter lifespan for the wipers. Summary of the Invention

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

[0005] In one aspect of this application, a windshield wiper control method is provided, applied to a vehicle, the vehicle including windshield wipers, a windshield, and a steering wheel, wherein a sensor is disposed on the steering wheel, the method comprising:

[0006] In response to a first operation on the sensor, the wiping mode of the windshield wiper is determined;

[0007] When the wiper's wiping mode is a custom wiping mode, in response to the operation of sliding a target sliding area on the sensor, a target wiping area is determined 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 portion of the complete wiping area of ​​the windshield.

[0008] Control the windshield wipers to perform a wiping operation on the target wiping area.

[0009] In this possible implementation, the wiping range of the windshield wipers can be adjusted to clean and wipe specific areas, allowing the wipers to target dirt and grime effectively, reducing wear and tear on the wipers and extending their lifespan. Furthermore, since the steering wheel is closest to the user, placing a sensor on it allows the user to determine the target wiping area by sliding their fingers across the sensor, simplifying operation and making the process simple and convenient. Additionally, determining the target wiping area by the user's sliding motion on the steering wheel sensor allows for more precise control of the wiper's wiping range.

[0010] In some embodiments, determining a target scraping area based on the target sliding area in response to an operation of sliding a target sliding area on the sensor includes:

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

[0012] Under the condition of satisfying the preset curvature constraint, the position at a preset distance from the boundary of the first scraping area is determined as the soft stop point;

[0013] The area between the soft stop point and the boundary of the first scraping area is defined as the second scraping area;

[0014] The target scraping area is determined based on the second scraping area and the first scraping area, and the target scraping area includes the first scraping area and the second scraping area.

[0015] In this possible implementation, the target wiping area is larger than the first wiping area, which ensures that the first wiping area can be completely wiped, allowing the wiper to completely clean the stains in the first wiping area and 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 determining the target wiping area based on the target sliding area in response to an operation of sliding a target sliding area on the sensor includes:

[0017] When the wiper's wiping mode is a custom wiping mode, in response to the operation of sliding a target sliding area on the sensor, the wiper's wiping area is adjusted from a third wiping area to the target wiping area, wherein the third wiping area is either the complete wiping area of ​​the wiper or a portion of the wiping area that is different from the target wiping area.

[0018] In this possible implementation, a method for determining the target wiping area is specifically provided in custom mode, improving the feasibility of this application. Furthermore, determining the target wiping area through a sliding operation is more convenient and faster than adjusting by inputting numerical values, thus increasing 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 wiper drive motor, 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 wiping operations on the target wiping area, which can more effectively remove stains on the windshield and focus on cleaning stubborn stains. Compared with traditional full-area wiping, it can more effectively keep the visible area of ​​the windshield clean and tidy, provide the driver with better visibility, and enhance driving safety.

[0021] In some embodiments, determining the wiping pattern of the windshield wipers in response to a first operation on the sensor includes:

[0022] In response to a first operation of pressing M1 times on the sensor, the wiper wiping mode 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 includes:

[0024] When the wiper's wiping mode is the target wiping mode, the wiping operation corresponding to the target wiping mode is executed. The target wiping mode includes maintenance mode, automatic wiping mode, intermittent wiping mode, or high-speed wiping mode. The maintenance mode is a mode that wipes at a preset speed in a preset area. The automatic wiping mode is a mode that automatically adjusts the wiping speed according to the amount of dirt. The intermittent wiping mode is a mode that wipes at a preset time interval. The high-speed wiping mode is a mode that wipes at the maximum wiping speed.

[0025] This possible implementation enhances the flexibility and adaptability of windshield wiper operation by providing users with a variety of wiper control modes. Users can select different wiper control modes based on varying environmental conditions to better cope with different weather conditions, thus ensuring unobstructed visibility. Furthermore, since each user has different wiper usage habits, multiple control modes can meet individual user needs.

[0026] In some embodiments, determining the wiping pattern of the windshield wipers in response to a first operation on the sensor includes:

[0027] In response to M2 presses on the sensor, the wiper wiping mode is determined to be 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, the wiping mode of the windshield wiper is determined to be the automatic wiping mode; or,

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

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

[0031] In this possible implementation, the wiper mode (automatic, intermittent, or high-speed) can be directly selected from custom mode, maintenance mode, automatic wiping mode, intermittent wiping mode, and high-speed wiping mode in the first operation; there is no need to first select the normal wiping mode and then select the automatic, intermittent, or high-speed wiping mode within the normal wiping mode. Directly determining the wiper mode in a single operation reduces the number of steps required by the user and increases the speed at which the user can select the wiper 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 a first operation on the sensor includes:

[0033] In response to an operation of pressing M3 times on the sensor, a normal swiping mode is determined, the normal swiping mode including the automatic swiping mode, the intermittent swiping mode and the high-speed swiping mode, where 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, the wiping mode of the windshield wiper is determined to be the automatic wiping mode; or,

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

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

[0037] In some embodiments, determining the wiping pattern of the windshield wipers in response to a first operation on the sensor includes:

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

[0039] In this possible implementation, by detecting the operational pressure of the first operation, it is possible to accurately distinguish between accidental touches and active operations, reduce the false trigger rate, and avoid misoperations caused by user accidental touches.

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

[0041] Another aspect of this application embodiment provides a windshield wiper control device applied to a vehicle, the vehicle including windshield wipers, a windshield, and a steering wheel, the steering wheel being provided with a sensor, the windshield wiper control device including:

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

[0043] The second determining module is used to determine a target wiping area based on the target sliding area in response to an operation of sliding a target sliding area on the sensor when the wiping mode of the wiper is a custom wiping mode. The target wiping area is the area where the wiper wipes the windshield, and the custom wiping mode is the mode in which the wiper wipes a portion of the complete wiping area of ​​the windshield.

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

[0045] The computer device provided in this application includes a memory and a processor. The memory stores a computer program that can run on the processor, and the processor executes the program to implement the method of this application.

[0046] The computer-readable storage medium provided in this application embodiment stores a computer program thereon, which, when executed by a processor, implements the method provided in this application embodiment.

[0047] The wiper control method, apparatus, computer device, and computer-readable storage medium provided in this application enhance the flexibility and adaptability of wiper operation by offering users a selection of wiper control modes, including automatic wiping mode, intermittent wiping mode, high-speed wiping mode, and custom mode. Users can choose different wiper control modes according to different environmental conditions, allowing the wipers to better cope with various weather conditions and ensuring unobstructed visibility. Furthermore, since each user has different wiper usage habits, multiple control modes can meet individual user needs. This reduces distractions during driving, allowing drivers to focus more on driving, further improving driving safety, and solving the technical problems mentioned in the background art.

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

[0063] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0064] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is 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 noted that the terms "first, second, third" used in the embodiments of this application are used to distinguish similar or different objects and do not represent a specific order of objects. It can be understood that "first, second, third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0066] With the rapid development of intelligent vehicle technology, automobiles are constantly innovating their functions and significantly improving their performance. As a key component that ensures clear visibility for drivers and guarantees driving safety, the evolution of windshield wipers' control methods has attracted much attention.

[0067] Traditional car windshield wiper controls involve the wipers cleaning the entire windshield surface when wiping away dirt. This means the wipers need to complete the entire wiping stroke, cleaning not only stained areas but also other clean areas of the windshield. This results in a larger wiping area for the wiper assembly when cleaning dirt, leading to faster wear and tear and a shorter lifespan for the wipers.

[0068] Therefore, this application provides a windshield wiper control method applied to a vehicle. The vehicle includes windshield wipers, a windshield, and a steering wheel. A sensor is disposed on the steering wheel. The method includes: determining a wiping mode of the windshield wipers in response to a first operation on the sensor; if the wiping mode of the windshield wipers is a custom wiping mode, determining a target wiping area based on the target sliding area in response to an operation of sliding a target sliding area on the sensor. The target wiping area is the area where the windshield wipers wipe the windshield, and the custom wiping mode is a mode in which the windshield wipers wipe a portion of the complete wiping area of ​​the windshield; and controlling the windshield wipers to perform a wiping operation on the target wiping area.

[0069] In this possible implementation, the wiping range of the windshield wipers can be adjusted to clean and wipe specific areas, allowing the wipers to target dirt and grime effectively, reducing wear and tear on the wipers and extending their lifespan. Furthermore, since the steering wheel is closest to the user, placing a sensor on it allows the user to determine the target wiping area by sliding their fingers across the sensor on the steering wheel, simplifying operation and making the process simple and convenient. In addition, determining the target wiping area by the user's sliding action on the steering wheel sensor allows for more precise control of the wiper's wiping range.

[0070] This application uses a windshield wiper control method applied in a vehicle controller as an example for illustration. However, it does not imply that this application's embodiments can only be applied to windshield wiper control in a vehicle controller.

[0071] The wiper control method provided in the embodiments of this application will be explained in detail below.

[0072] Figure 1 This is a flowchart illustrating a windshield wiper control method provided in this application. This method can be applied to a vehicle controller, which may include any control unit and / or processor with functions such as processing, control, identification, and calculation. See also... Figure 1 This application provides a windshield wiper control method, which includes:

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

[0074] In response to the user's first action, the vehicle controller determines the wiper wiping mode. This mode can be any of the following: custom mode, maintenance mode, automatic wiping mode, intermittent wiping mode, or high-speed wiping mode. The automatic wiping mode automatically adjusts the wiping 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 increased rain on the windshield, the wipers automatically increase their wiping speed; conversely, when the rain decreases, the wiping speed decreases accordingly. This mode allows the driver to focus more on driving without frequently manually adjusting the wipers, improving driving safety and convenience.

[0075] This intermittent wiping mode involves wiping at preset time intervals. The driver can adjust the interval according to the actual situation, typically from a few seconds to tens of seconds. This mode is suitable for light rain, effectively clearing water from the windshield without obstructing vision or causing excessive wear on the wiper blades due to overly frequent wiping.

[0076] This high-speed wiping mode operates at maximum wiping speed, allowing the wipers to continuously wipe at the fastest possible speed. It is typically used in heavy rain or downpours to quickly remove large amounts of water from the windshield, ensuring good visibility for the driver.

[0077] This custom mode allows you to wipe only a portion of the full wiping area of ​​the windshield wipers. In custom mode, the wipers can wipe the selected area at a speed and frequency set by the user. It allows for targeted wiping of the chosen area, effectively cleaning specific areas and improving cleaning results. It also enables personalized wiper adjustments, enhancing the adaptability and flexibility of wiper control.

[0078] This maintenance mode involves wiping the windshield wipers at a preset speed within a pre-defined area. In this mode, the vehicle controller can quickly activate the wipers, causing them to wipe in a single, controlled manner within the designated area, regardless of the selected wiping mode or area. This allows for a more direct observation of the wiper's basic operation, facilitating rapid inspection and repair, and pinpointing potential problems. Furthermore, when other wiping modes malfunction, such as issues with wiping area selection and / or wiping speed adjustment, this maintenance mode can be selected to bypass these restrictions and perform rapid wiping.

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

[0080] 102. When the wiper wiping mode is set to custom wiping mode, in response to the operation of sliding the target sliding area on the sensor, the target wiping area is determined based on the target sliding area.

[0081] When the wiper wiping mode is set to custom wiping mode, in response to the operation of sliding a target sliding area on the sensor, the vehicle controller determines the target wiping area based on the target sliding area. The target wiping area is the area where the wiper wipes the windshield. Custom wiping mode is a mode in which the wiper wipes a portion of the complete wiping area of ​​the windshield.

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

[0083] In custom mode, the vehicle controller can wipe specific areas within the full wiping area of ​​the windshield wipers. In custom mode, the wipers can wipe in user-selected areas at user-defined speeds and frequencies. Selected areas can be targeted for focused cleaning, resulting in improved cleaning performance. This also allows for personalized wiper adjustments, enhancing the adaptability and flexibility of wiper control.

[0084] The first operation described above will be described in detail below.

[0085] In some embodiments, the first operation described above may be an operation on the sensor. Specifically, the first operation may be a sliding operation and / or a pressing operation on the sensor, such as 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 be other types of operations, such as a clicking operation on the display screen, etc. The specific operation is not limited here.

[0086] For example, the first operation can be the user's operation on any device in the vehicle that can interact with the user. For example, the first operation can be the operation on the display screen in the vehicle, the operation on the steering wheel, the operation on the sensors, etc.

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

[0088] For example, the first operation is a sliding operation on the sensor along a first direction. If the pressure exerted on the sensor by the sliding operation is greater than 3N, the vehicle controller can determine that the corresponding automatic wiping mode is the wiper wiping mode; 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 wiper wiping mode.

[0089] It is understandable that the requirement that the vehicle controller will only determine the corresponding wiper wiping mode when the pressure on the sensor during the first operation exceeds a threshold is a condition imposed to prevent false triggering. In addition, other limitations can be imposed on this first operation. For example, the vehicle controller may only determine the corresponding wiper wiping mode based on the first operation if the operation time of the first operation exceeds a threshold; however, specific limitations are not specified here.

[0090] It is understood that in the embodiments of this application, the first operation can be limited to prevent accidental touches, and the corresponding steps will only be executed when preset conditions are met; in addition, other operations can also be limited to prevent accidental touches in the same way, 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. If the pressure applied to the sensor by the sliding operation is greater than 3N, the vehicle controller will control the wipers to perform a 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 wipers to perform a wiping operation on the target wiping area.

[0092] It is understandable that the requirement that the vehicle controller will only control the wipers to perform a wiping operation when the pressure on the sensor during a sliding operation exceeds a threshold is a condition imposed to prevent false triggering. In addition, other limitations can be imposed on this sliding operation. For example, the vehicle controller may only control the wipers to perform a wiping operation when the operation time of the sliding operation exceeds a threshold; however, specific limitations are not specified here.

[0093] In this possible implementation, by detecting the operational pressure of the first operation, it is possible to accurately distinguish between accidental touch and active operation, reduce the false trigger rate, avoid misoperation caused by user accidental touch, and improve the safety of users when driving vehicles.

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

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

[0096] In this embodiment of the application, the first operation that can be used to determine the wiping mode of the windshield wiper as a custom wiping mode can be an M1 pressing operation, or a pressing operation of other numbers, or a single sliding operation, or multiple sliding operations, and is not limited here.

[0097] In some embodiments, in custom mode, the proportion of the target wiping area on the complete wiping area of ​​the wiper corresponds to the proportion of the target sliding area on the complete sliding area of ​​the sensor. After the user slides the target sliding area on the sensor, the vehicle controller can determine the corresponding proportion and position range of the target sliding area on the complete sliding area of ​​the sensor, and then determine the target wiping area of ​​the target sliding area on the complete wiping area of ​​the wiper based on the above-mentioned proportion and position range information.

[0098] For example, Figure 2 As shown, the complete sliding area data of the sensor is categorized as 0 to 90°, and the complete wiping area data of the wiper is categorized as 0° to 90°. When a user slides their device within the 30° to 60° range of the sensor's complete sliding area, this 30° to 60° range is defined as the target sliding area. Correspondingly, the target wiping area is the 30° to 60° range. Therefore, 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, the user slides within a 30° to 60° area of ​​the sensor's full sliding area; this 30° to 60° area is the target sliding area. Correspondingly, the target swiping area corresponding to this target sliding area is a fan-shaped area C1-O-D1, which is the area from 30° to 60°.

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

[0101] A first scraping area corresponding to the target sliding area is determined; under the condition of satisfying the preset curvature constraint, the position at a preset distance from the boundary of the first scraping area is determined as the soft stop point; the area between the soft stop point and the boundary of the first scraping area is determined as the second scraping area; based on the second scraping area and the first scraping area, a target scraping area is determined, the target scraping area including the first scraping area and the second scraping area.

[0102] To ensure the target swiping area is completely swiped, the defined target swiping area can be larger than the initial swiping area indicated by the user's swipe gesture. For example, such as... Figure 2 As shown, the sensor's complete sliding area is categorized as 0 to 90 degrees, and the wiper's complete wiping area is categorized as 0° to 90°. When a user slides their device within a 30° to 60° range of the sensor's complete sliding area, this 30° to 60° range is defined as the target sliding area. Correspondingly, the first wiping area corresponding to this target sliding area is the 30° to 60° range. Figure 2 The sector-shaped region C1-O-D1 in the middle.

[0103] To ensure the first scraping area corresponding to the target sliding area is completely scraped, the positions at a preset distance from the boundary of the first scraping area can be defined as soft stops. The boundaries of the first scraping area are at 30° and 60°, and the preset distance is 2°, therefore the determined soft stops are at 28° and 28°. The corresponding second area includes the area from 28° to 30° and the area from 60° to 62°, i.e. Figure 2 The sector regions C2-O-C1 and D1-O-D2 are shown in the figure.

[0104] Then, based on the second swiping area (28° to 30° and 60° to 62°) and the first swiping area (30° to 60°), the target swiping area is determined to be the area between 28° and 62°. Figure 2 The fan-shaped region C2-O-D2 in the target scraping area includes a first scraping area and a second scraping area.

[0105] 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 a sensor, determining a target wiping area based on the target sliding area includes:

[0106] When the wiper wiping mode is set to custom wiping mode, in response to the operation of sliding the target wiping area on the sensor, the vehicle controller adjusts the wiper wiping area from the third wiping area to the target wiping area. The third wiping area is either the complete wiping area of ​​the wiper or a portion of the wiping area that is different from the target wiping area.

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

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

[0109] In some embodiments, the windshield wipers on the vehicle are driven by a 360° continuously rotating motor via a crank-rocker mechanism. The crank is mounted on the wiper motor shaft. When the wiper motor moves 360°, the crank on the output shaft drives the wiper blades to swing back and forth, sweeping a fan-shaped area on the windshield. In custom mode, to achieve focused wiping of the target area, the vehicle controller can reverse the wiper motor when the wiper reaches one edge of the target area, causing the wiper to swish in the opposite direction. When it reaches the other edge of the target area, the wiper motor is reversed again. This effectively adjusts the wiping range of the wiper to the target area by controlling the wiper motor. This cycle repeats to achieve wiping of the target area.

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

[0111] In some embodiments, the wiper is an adjustable wiping area wiper, exemplarily, such as... Figure 3As shown, the windshield wiper assembly 300 may include a crank 301, an adjustment device 302, a connecting rod 303, a wiper 304, a wiper motor 305 for driving the wiper to perform wiping, and an adjustment motor 306 for adjusting the length of the crank. Driven by the adjustment motor 306 in the adjustment device 302, the crank 301 can extend and retract along its extension direction; the connecting rod 303 connects the crank 301 and the wiper 304. Driven by the wiper motor 305, the crank 301 can drive the connecting rod 303 to move, and the connecting rod 303 can drive the wiper 304 to rotate around point A in the figure to clean and wipe the windshield, preventing stains on the windshield from obstructing the driver's vision.

[0112] In this embodiment, the crank 301 can extend and retract along its extension direction, changing its rotation radius. Therefore, by changing the rotation radius of the crank 301, and through the transmission of the connecting rod 303, the wiping area of ​​the wiper 304 can be changed, enabling the wiper to clean and wipe the target area. This allows the wiper 304 to specifically clean stains, effectively reducing wear on the wiper and improving its lifespan. The adjusting device 302 is mounted on the crank 301 and drives its extension and retraction. This allows the driver to control the extension and retraction of the crank 301 via the extension drive component, improving the accuracy of the crank 301's extension and retraction, and thus enabling more precise control of the wiper 304's wiping area.

[0113] In some embodiments, the wiper is an adjustable wiper with the aforementioned wiping area. In custom mode, the rotation radius of the crank 301 can be adjusted by controlling the adjustment device 302, thereby changing the wiping area of ​​the wiper 304. For example, Figure 3 As shown, by changing the crank 301 from Figure 3 When the F1 point is adjusted to the F2 point, the corresponding wiper wiping area is changed from the fan-shaped area AOB to the fan-shaped area COD. This fan-shaped area COD includes the target wiping area, thereby achieving wiping of the target wiping area.

[0114] It's worth noting that in custom mode, in response to the action of sliding the target area on the sensor, the vehicle controller controls the wipers to perform wiping operations on the target area. This allows for more targeted removal of stains on the windshield, and stubborn stains can be cleaned in a focused manner. Compared to traditional full-area wiping, it can more effectively keep the visible area of ​​the windshield clean and tidy, providing the driver with better visibility and enhancing driving safety. At the same time, the wipers only work on the stained areas, reducing unnecessary friction and contact with the windshield, thereby reducing the wear rate of the wiper blades, extending the wiper's lifespan, and saving on the cost and frequency of wiper replacement.

[0115] In some embodiments, a portion of the sensor is a sliding area, and a portion is a pressing area. For example... Figure 4 As shown, Figure 4 The sensor includes a first region, a second region, and a third region. The first and second regions are areas that can be pressed, and the third region is an area that can be slid. Alternatively, the sensor in this application can also be a sensor where all areas can be slid and some areas can be pressed; or a sensor where all areas can be pressed and some areas can be slid; or a sensor where all areas can be both slid and pressed. The specific type is not limited here.

[0116] In some embodiments, such as Figure 5 As shown, the sensor can be located in the center area 501, the left outer grip area 502, the right outer grip area 503, the left control area 504, and the right control area 505 on the steering wheel. In addition, it can 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 detailed below:

[0118] 1. Reduce driver distraction and improve driving safety.

[0119] When drivers control the windshield wipers using sensors on the steering wheel, they can keep their eyes on the road and their hands on the steering wheel. Traditional center console buttons or in-vehicle screens require drivers to turn their heads and reach out to operate, while steering wheel buttons are located within the natural grip area of ​​both hands (such as around the "3 o'clock" and "9 o'clock" areas). Operation requires only a light touch or slight movement of the fingers, and the driver's eyes do not need to deviate from the road ahead. This avoids the dangerous actions of taking one hand off the steering wheel or looking down at the screen, significantly reducing the risk of accidents caused by distraction.

[0120] II. Optimize operational efficiency and enhance the driving experience.

[0121] Placing sensors on the vehicle's steering wheel makes blind operation more user-friendly for drivers, reducing cognitive load. The fixed and ergonomically designed position of the sensors on the steering wheel (e.g., within reach of the thumb and forefinger) allows drivers to operate the vehicle through muscle memory, without needing to look at buttons or think about the operation logic. This is especially suitable for rapid response in complex road conditions.

[0122] In some embodiments, the wiper wiping mode is a maintenance mode, where the wipers are controlled to perform wiping operations in response to a pressing operation on the sensor. For example, in maintenance mode, the wipers are controlled to perform wiping operations in response to two consecutive pressing operations on the sensor. Alternatively, in maintenance mode, other operations can trigger the vehicle controller to control the wipers to perform wiping operations, which are not limited here.

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

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

[0125] In some embodiments, the vehicle also includes a steering wheel, on which the aforementioned sensors are disposed. For example... Figure 5 As shown, the sensor can be positioned around the circumference of the steering wheel. When driving, the driver's hands are typically placed 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 provides easier control. However, the sensor can also be positioned at other locations on the steering wheel, such as the center, without limitation here.

[0126] It is worth noting that by placing the wiper control sensor on the steering wheel, the driver can easily control the wipers without taking their hands off the wheel. This allows the driver to react more quickly and activate or adjust the wipers in the event of sudden rainfall or when it is necessary to quickly clear water from the windshield. This enables the driver to adjust the wiper mode according to the rainfall situation without distracting their attention, thereby improving visibility and enhancing driving safety.

[0127] In some embodiments, when the wiper's wiping mode 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 in which wiping is performed in a preset area at a preset wiping speed. The automatic wiping mode is a mode in which the wiping speed is automatically adjusted according to the amount of dirt. The intermittent wiping mode is a mode in which wiping is performed at a preset time interval. The high-speed wiping mode is a mode in which wiping is performed at the maximum wiping speed.

[0128] For example, in the aforementioned automatic wiping mode, the vehicle controller can automatically adjust the wiping speed based on the amount of dirt on the vehicle. For instance, the vehicle controller can automatically adjust the wiping speed based on the amount of rain detected by the vehicle's rain sensor. When the sensor detects an increase in rainwater on the windshield, the wipers will automatically increase their wiping speed; conversely, when the rainwater decreases, the wiping speed will decrease accordingly. This mode allows the driver to focus more on driving without frequently adjusting the wipers, improving driving safety and convenience.

[0129] In the intermittent wiping mode described above, the vehicle controller can control the wipers to wipe at preset time intervals. The driver can adjust the interval time according to the actual situation, generally ranging from a few seconds to tens of seconds. This mode is suitable for light rain, as it can quickly clear rainwater from the windshield without obstructing vision or causing excessive wear on the wiper blades due to overly frequent wiping.

[0130] In the high-speed wiping mode described above, the vehicle controller can control the wipers to wipe at the maximum speed, allowing for continuous wiping at the fastest possible speed. This is typically used in heavy rain or downpours to quickly remove large amounts of water from the windshield, ensuring good visibility for the driver.

[0131] In the aforementioned maintenance mode, the vehicle controller can quickly activate the windshield wipers, causing them to wipe within a fixed area using a single operating mode, regardless of the selected wiping mode or area. This allows for a more direct observation of the wipers' basic operating status, facilitating rapid inspection and repair, and pinpointing faults.

[0132] It's worth noting that by providing users with a selection of wiper control modes, including automatic wiping, intermittent wiping, high-speed wiping, and a custom mode, the flexibility and adaptability of the wipers are enhanced. Users can choose different wiper control modes according to different environmental conditions. For example, different rainfall intensities require different wiper speeds to maintain a clear view of the windshield. Light rain can use a low-speed intermittent mode, heavy rain requires a high-speed continuous mode, and torrential rain may necessitate even faster speeds or an additional enhanced mode. Multiple control modes allow the wipers to better cope with various weather conditions, thus ensuring unobstructed visibility.

[0133] Furthermore, since each user has different windshield wiper usage habits, multiple control modes can meet individual user needs. Some users prefer longer wiper intervals, while others want the wipers to stop at different positions after each wipe. Through the custom mode, users can set it according to their preferences, increasing driving comfort. This reduces distractions during 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 the wipers and motor during wiper operation. For example, in light rain or intermittent rainfall, using the intermittent mode can prevent the wipers from working continuously for extended periods, reducing the frequency of friction between the wiper blades and the windshield, thereby extending the wiper's lifespan and saving on replacement costs.

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

[0136] In response to an M3 press operation on the sensor, a normal swiping mode is determined. The normal swiping mode includes automatic swiping mode, intermittent swiping mode and high-speed swiping mode, where M3 is an integer greater than or equal to 1.

[0137] In normal wiping mode, in response to a sliding operation of the sensor along a first direction, the wiping mode of the windshield wipers is determined to be automatic wiping mode; or,

[0138] In normal wiping mode, in response to a sliding operation of the sensor along the second direction, the wiping mode of the windshield wipers is determined to be intermittent wiping mode; or,

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

[0140] For example, such as Figure 6 As shown:

[0141] 601. In response to operation B1, determine the normal scraping mode.

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

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

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

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

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

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

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

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

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

[0151] Understandably, since the normal control mode includes automatic scraping mode, intermittent scraping mode and high-speed scraping mode, further determination of the scraping mode is still needed.

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

[0153] In some embodiments, such as Figure 7 As shown in Table 1, the correspondence between the specific operation of the first step and the wiper control mode is as follows:

[0154] Table 1

[0155]

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

[0157] Determining the wiper wiping mode can involve multiple steps, meaning the first operation may include several specific steps. Alternatively, the first operation can also consist of only one specific step, as described below:

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

[0159] In response to M2 presses on the sensor, the wiper wiping mode is determined to be maintenance mode, where M2 is an integer greater than or equal to 1; or,

[0160] In response to a sliding operation of the sensor along a first direction, the wiping mode of the windshield wiper is determined to be automatic wiping mode;

[0161] or,

[0162] In response to a sliding operation of the sensor in the second direction, the wiping mode of the windshield wiper is determined to be an intermittent wiping mode;

[0163] or,

[0164] In response to a sliding operation of the sensor along a third direction, the wiping mode of the windshield wiper is determined to be high-speed wiping mode.

[0165] For example, such as Figure 8As shown: In response to operation A, the vehicle controller determines the maintenance mode as the windshield wiper wiping mode. For example, in response to M2 consecutive presses on the sensor, specifically 4 consecutive presses on the sensor, the vehicle controller can determine the maintenance wiping mode as the windshield wiper wiping mode.

[0166] or,

[0167] In response to operation B, the vehicle controller determines the high-speed wiping mode as the windshield wiper wiping mode. For example, in response to a sliding operation on the sensor along a third direction, such as a sliding operation on the sensor first in a clockwise direction and then in a counterclockwise direction, the vehicle controller determines the high-speed wiping mode as the windshield wiper wiping mode.

[0168] or,

[0169] In response to operation C, the vehicle controller determines the automatic wiping mode as the windshield wiper wiping mode. Exemplarily, in response to a sliding operation on the sensor along a first direction, such as specifically a sliding operation on the sensor in a counter-clockwise direction, the vehicle controller determines the automatic wiping mode as the windshield wiper wiping mode; or,

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

[0171] In response to operation E, the vehicle controller determines the custom mode as the windshield wiper wiping mode. For example, in response to a series of M1 consecutive presses on the sensor, such as specifically three consecutive presses on the sensor, the vehicle controller determines the custom mode as the windshield wiper wiping mode.

[0172] In addition, the vehicle controller can also respond to other types of operations and determine the corresponding other wiper control modes, which are not specified here.

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

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

[0175] Table 2

[0176]

[0177] In this possible implementation, the wiper mode (automatic, intermittent, or high-speed) can be directly selected from custom mode, maintenance mode, automatic wiping mode, intermittent wiping mode, and high-speed wiping mode in the first operation; there is no need to first select the normal wiping mode and then select the automatic, intermittent, or high-speed wiping mode within the normal wiping mode. Directly determining the wiper mode in a single operation reduces the number of steps required by the user and increases the speed at which the user can select the wiper mode.

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

[0179] In some embodiments, the second operation can be used to instruct the determination of wiping parameters in the wiping mode of the windshield wipers, specifically as follows: Figure 9 As shown:

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

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

[0182] 902. In response to the second operation, determine the brush parameters.

[0183] After determining the wiper wiping mode, in response to the second operation, the vehicle controller determines the wiping parameters in the wiper wiping mode, including wiping area parameters and wiping speed parameters. The wiping area parameters indicate the area where wiping is performed, and the wiping speed parameters indicate the speed at which wiping is performed.

[0184] For example, the second operation may be a sliding operation on a target area on the sensor, in response to which the vehicle controller can determine the corresponding target brushing area parameters.

[0185] For example, the second operation could be pressing the sensor a different number of times. In high-speed swiping mode, in response to M4 presses on the sensor, the vehicle controller can determine the swiping speed parameter corresponding to the high-speed swiping mode. For example, in custom mode, two presses correspond to a swiping speed increase of 1, and three presses correspond to a swiping speed decrease of 1. With an initial swiping speed of 5, in response to two presses on the sensor, the vehicle controller updates the swiping speed to 6.

[0186] For example, the second operation could be a pressing operation on different areas of the sensor, where pressing on different areas indicates an increase or decrease in the brush speed parameter. For example Figure 4 As shown, the sensor may include a first area and a second area. Pressing the first area indicates an increase of 1 in the wiping speed, and pressing the second area indicates a decrease of 1 in the wiping speed. With an initial wiping speed of 5, in response to a press on the first area, the vehicle controller updates the wiping speed to 6. With an initial wiping speed of 5, in response to a press on the second area, the vehicle controller updates the wiping speed to 4.

[0187] It is understood that, in the embodiments of this application, after determining the wiping mode of the windshield wiper 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 various wiping modes of the windshield wiper, at least one wiping mode supports adjustable wiping parameters.

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

[0189] In the wiper wiping mode, the vehicle controller controls the wipers to perform wiping actions in the target wiping area indicated by the above wiping parameters, and at the wiping speed indicated by the above wiping parameters.

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

[0191] In some embodiments, since the second operation indicates all operations that trigger the wipers to perform wiping in the wiper wiping mode, the second operation may include at least one specific operation step. For example, the second operation 1 may determine the corresponding wiping area, the second operation 2 may determine the corresponding wiping speed, and 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 a second operation, providing users with more flexible wiper control options and enabling more precise wiper control.

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

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

[0195] In response to the user's first operation, the vehicle controller determines the wiper wiping mode corresponding to the first operation. The wiper wiping mode can be any one of the following: custom mode, maintenance mode, automatic wiping mode, intermittent wiping mode, and high-speed wiping mode.

[0196] For example, such as Figure 10 As shown, the vehicle controller can respond to operation A by determining the maintenance mode as the wiper wiping mode. Alternatively, the vehicle controller can respond to operation B by determining the high-speed wiping mode as the wiper wiping mode. Alternatively, the vehicle controller can respond to operation C by determining the automatic mode as the wiper wiping mode. Alternatively, the vehicle controller can respond to operation D by determining the intermittent wiping mode as the wiper wiping mode. Alternatively, the vehicle controller can respond to operation E by determining the custom mode as the wiper wiping mode. The specific determination methods are described above and will not be repeated here.

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

[0198] The vehicle controller checks if the pressure applied during the first operation exceeds a preset threshold. If so, it proceeds with subsequent steps. If the pressure applied during the first operation does not exceed the preset threshold, the vehicle controller does not proceed with subsequent steps. The specific determination method can be found in the previous 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 a threshold. If it is, the subsequent steps are executed. If it is not greater, the vehicle controller will not execute the subsequent steps. The pressing pressure detection for other operations is the same, and will not be elaborated here.

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

[0201] If 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 wiper wiping mode. The wiping parameters include wiping area parameters and wiping speed parameters. The wiping area parameters indicate the area where wiping is performed, and the wiping speed parameters indicate the speed at which wiping is performed.

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

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

[0204] If the pressing pressure of the second operation of the vehicle controller exceeds a preset threshold, the subsequent steps are executed. If the pressing pressure of the second operation does not exceed the preset threshold, the vehicle controller will not execute the subsequent steps. The specific determination method can be found in the previous description and will not be repeated here.

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

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

[0207] In addition, other implementation methods are possible, such as in some embodiments, such as 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 scraping mode.

[0209] In response to operation B1, the vehicle controller determines the normal wiping mode among multiple control modes, which may include a custom mode, a maintenance mode, and a normal wiping mode. Specifically, in response to the first operation, the vehicle controller determines the normal wiping mode among these three modes. This normal wiping mode includes automatic wiping mode, intermittent wiping mode, and high-speed wiping mode.

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

[0211] The vehicle controller determines whether the pressing pressure of operation B1 is greater than a threshold. If the pressing pressure of the first operation is greater than the preset threshold, the subsequent steps are executed. If the pressing pressure of the first operation is not greater than the preset threshold, the vehicle controller will 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 the wiper wiping mode in normal wiping mode.

[0213] In response to operation B2, the vehicle controller determines one of the wiping modes among the normal wiping modes, namely automatic wiping mode, intermittent wiping mode, and high-speed wiping mode, as the wiping mode of the windshield wipers.

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

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

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

[0217] The vehicle controller determines whether the pressing pressure of operation B2 is greater than a threshold. If the pressing pressure of the first operation is greater than the preset threshold, the subsequent steps are executed. If the pressing pressure of the first operation is not greater than the preset threshold, the vehicle controller will 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 the brush parameters.

[0219] If 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 wiper wiping mode. The wiping parameters include wiping area parameters and wiping speed parameters. The wiping area parameters indicate the area where wiping is performed, and the wiping speed parameters indicate the speed at which wiping is performed.

[0220] For example, such as Figure 10 As shown, in custom mode, the vehicle controller can respond to operation D to determine the corresponding target swiping area. The specific determination method can be found in the previous description and will not be repeated here.

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

[0222] If the pressing pressure of the second operation of the vehicle controller exceeds a preset threshold, the subsequent steps are executed. If the pressing pressure of the second operation does not exceed the preset threshold, the vehicle controller will not execute the subsequent steps. The specific determination method can be found in the previous description and will not be repeated here.

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

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

[0225] The vehicle controller may include, but is not limited to, an on-board terminal, electronic control devices, and body control devices. The functions implemented by this method can be achieved by the processor in the vehicle controller calling program code. Of course, the program code can 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 flowcharts above are shown sequentially as indicated by the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts above may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the sub-steps or stages of other steps.

[0227] Based on the foregoing embodiments, this application provides a wiper control device, which includes various modules and units included in each module, and can be implemented by a processor; of course, it can also be implemented by specific logic circuits; in the implementation process, the processor can be a central processing unit (CPU), microprocessor (MPU), digital signal processor (DSP) or field programmable gate array (FPGA), etc.

[0228] Figure 12 This is a schematic diagram of a wiper control device provided in an embodiment of this application. See also... Figure 12 This device is used in a vehicle, which includes windshield wipers, a windshield, and a steering wheel. A sensor is located on the steering wheel. The windshield wiper control device includes:

[0229] The first determining module 1201 is used to determine the wiping mode of the windshield wiper in response to a first operation on the sensor;

[0230] The second determining module 1202 is used to determine the target wiping area based on the target sliding area in response to the operation of sliding the target sliding area on the sensor when the wiping mode of the wiper is a custom wiping mode.
