These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments.

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0047] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0048] Windshield wipers are essential in vehicles, as they clear rainwater or dirt from the windshield, reducing obstruction of the driver's view and improving driving safety.

[0049] In the prior art, the windshield wipers move within a fixed cleaning range, which is referred to in this application as the regular cleaning range. The regular cleaning range has a first upper boundary and a first lower boundary. The area between the first upper boundary and the A-pillar of the vehicle is the windshield wiper blind spot, and the windshield wipers cannot clean the dirt in the windshield wiper blind spot.

[0050] For example, Figure 1 A schematic diagram of the wiper blind spot provided in this application, such as Figure 1 As shown in the figure, the gray area represents the regular cleaning range. It can be seen that there is an area between the first upper boundary of the regular cleaning and the A-pillar of the vehicle, which is the area within the dashed box. This area is the blind spot of the windshield wipers.

[0051] Since windshield wipers cannot clean the blind spot, dirt in the blind spot can affect the driver's vision and pose a safety hazard. Therefore, there is an urgent need for a windshield wiper control method that can control the wipers to clean the blind spot.

[0052] To address the problems existing in the prior art, the inventors, during their research on windshield wiper control methods, discovered that to achieve cleaning of the wiper blind spot, regular cleaning conditions and blind spot cleaning conditions can be set. When the regular cleaning conditions are determined to be met, or a regular cleaning command is received, the wipers are controlled to enter the regular cleaning mode to clean the vehicle's windshield; when the blind spot cleaning conditions are determined to be met, or a blind spot cleaning command is received, the wipers are controlled to enter the blind spot cleaning mode to clean the blind spot. Based on the above inventive concept, the wiper control scheme of this application was designed.

[0053] The entity executing the wiper control method in this application can be a vehicle control unit (VCU), or an on-board terminal, server, etc. This application does not limit it. The following explanation uses VCU as an example.

[0054] The following provides examples illustrating the application scenarios of the wiper control method provided in this application.

[0055] For example, in this application scenario, after the vehicle has not been used for a long time, the driver needs to drive the vehicle and controls the windshield wipers to clean the windshield. At this time, the blind spot of the wipers is not cleaned.

[0056] After the vehicle is powered on, the camera inside the vehicle captures images of the wiper blind spot and transmits them to the VCU. The VCU processes the images to obtain and store the degree of dirtiness in the wiper blind spot. It then uses this information to determine the wiper setting and the current rainfall.

[0057] The VCU can determine if the degree of dirt in the wiper blind spot is greater than the preset dirt threshold, the wiper mode is automatic, and the current rainfall is less than or equal to the preset rainfall threshold that affects driving. In other words, the blind spot cleaning conditions are met, indicating that the wiper blind spot needs to be cleaned. Then, the VCU controls the wipers to enter the blind spot cleaning mode to clean part or all of the wiper blind spot.

[0058] In other words, based on the acquired blind spot cleaning data and the correspondence between the preset cleaning data and the execution parameters, the blind spot cleaning execution parameters are determined. The blind spot cleaning data includes at least one of the following: wiper model, ambient temperature, current rainfall, and degree of dirt in the wiper blind spot. The blind spot cleaning execution parameters include the blind spot cleaning range and the blind spot cleaning speed. Then, based on the blind spot cleaning execution parameters, part or all of the wiper blind spot is cleaned.

[0059] The blind spot cleaning mode has a second upper boundary and a second lower boundary for the blind spot cleaning range; the second upper boundary is located between the first upper boundary and the vehicle's A-pillar, and the second lower boundary is located between the first upper boundary and the first lower boundary.

[0060] It should be noted that the normal cleaning mode is the mode in the existing technology where the wipers are set to automatic mode. In normal cleaning mode, the wiping frequency of the wipers will be adjusted according to the amount of rain, and the wipers will wipe within the normal cleaning range.

[0061] It should be noted that the above scenario is only an example of an application scenario provided by the embodiments of this application. The embodiments of this application do not limit the actual form of the various devices included in the scenario, nor do they limit the interaction method between devices. In the specific application of the solution, it can be set according to actual needs.

[0062] The technical solution of this application will now be described in detail through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0063] Figure 2a This is a flowchart illustrating an embodiment of the windshield wiper control method provided in this application. This embodiment describes how the VCU controls the wipers to enter a normal cleaning mode to clean the vehicle's windshield, or controls the wipers to enter a blind spot cleaning mode to clean the blind spots. The method in this embodiment can be implemented through software, hardware, or a combination of both. Figure 2a As shown, the wiper control method specifically includes the following steps:

[0064] S201: If it is determined that the normal cleaning conditions are met, or a normal cleaning instruction is received, control the windshield wipers to enter the normal cleaning mode to clean the windshield of the vehicle.

[0065] In order to determine whether the windshield needs to be cleaned, and if so, how to clean it, the VCU needs to determine whether to enter a cleaning mode, and if so, which cleaning mode to enter.

[0066] In this step, if the VCU determines that the normal cleaning conditions are met, or receives a normal cleaning command, it controls the windshield wipers to enter the normal cleaning mode to clean the vehicle's windshield.

[0067] In one implementation, the normal cleaning conditions are: the current rainfall is greater than a preset rainfall threshold that affects driving, the windshield wipers are in automatic mode, and the left turn signal is off.

[0068] The regular cleaning mode has a first upper boundary and a first lower boundary for the regular cleaning range; the area between the first upper boundary and the vehicle's A-pillar is the wiper blind spot.

[0069] If the normal cleaning conditions are met, it means that driving would be affected if the wipers were not turned on under the current rainfall, the VCU can control the operation of the wipers, and the vehicle does not need to turn left, only the normal cleaning range needs to be cleaned. Therefore, the wipers are controlled to enter the normal cleaning mode.

[0070] It should be noted that the preset rain threshold affecting driving is the minimum amount of rain that would affect the driver's driving without the windshield wipers on, and can be 5%, 7%, 10%, etc. This application does not limit the preset rain threshold affecting driving; it can be determined according to actual circumstances.

[0071] The VCU can receive regular cleaning commands in several ways: First, a self-reset button is installed in the vehicle; the driver presses this button, and the VCU receives the command. Second, a regular cleaning button is displayed on the vehicle's terminal device screen; the driver clicks this button, and the VCU receives the command. Third, a multi-position switch is installed in the vehicle, with one position designated for entering regular cleaning mode; the user switches this switch to this position, and the VCU receives the command. Fourth, the user sends a regular cleaning command to the VCU using a terminal device, and the VCU receives the command. This application does not limit the method by which the VCU receives regular cleaning commands; the method can be determined based on actual circumstances.

[0072] It should be noted that the wiper settings can be off, automatic, high speed, low speed, etc. When the wipers are in high speed or low speed mode, they wipe continuously, with the high speed wiping faster than the low speed. In automatic mode, the VCU determines whether the wipers need to be turned on and controls their operation when this is determined. When the wipers are in off mode, they do not work.

[0073] S202: If the blind spot cleaning conditions are determined to be met, or a blind spot cleaning command is received, control the wipers to enter the blind spot cleaning mode to clean part or all of the wiper blind spot.

[0074] In this step, if the VCU determines that the blind spot cleaning conditions are met, or receives a blind spot cleaning command, it controls the wipers to enter the blind spot cleaning mode to clean part or all of the wiper blind spot.

[0075] In one implementation, the blind spot cleaning conditions are: the degree of dirt in the wiper blind spot is greater than a preset dirt threshold, the wiper is in automatic mode, and the current rainfall is less than or equal to a preset rainfall threshold that affects driving.

[0076] If the blind spot cleaning conditions are met, it means that the wiper blind spot is dirty, the VCU can control the operation of the wipers, and the current rainfall does not affect driving. If the wiper blind spot needs to be cleaned, the wipers will be controlled to enter the blind spot cleaning mode.

[0077] It should be noted that the preset dirt threshold can be 30%, 40%, 50%, 60%, etc. This application embodiment does not limit the preset dirt threshold, and it can be determined according to the actual situation.

[0078] The VCU can receive blind spot cleaning commands in several ways: First, the vehicle may have a self-reset button; pressing this button activates the blind spot cleaning mode. Second, a blind spot cleaning button may be displayed on the vehicle's terminal device; clicking this button activates the command. Third, the vehicle may have a multi-position switch, with one position designated for blind spot cleaning mode; switching this position activates the command. Fourth, the user may send a blind spot cleaning command to the VCU via a terminal device. This application does not limit the method by which the VCU receives the blind spot cleaning command; the method can be determined based on actual circumstances.

[0079] The specific process of VCU controlling the wipers to enter the blind spot cleaning mode to clean part or all of the wiper blind spot is as follows: Based on the acquired blind spot cleaning data and the correspondence between the preset cleaning data and the execution parameters, the blind spot cleaning execution parameters are determined; then, the blind spot is cleaned part or all of the wiper blind spot according to the blind spot cleaning execution parameters.

[0080] Blind spot cleaning data includes at least one of the following: wiper model, ambient temperature, current rainfall, and degree of dirt in the wiper blind spot. Blind spot cleaning execution parameters include the blind spot cleaning range and the blind spot cleaning speed.

[0081] It should be noted that the blind spot cleaning execution parameters also include the blind spot cleaning duration.

[0082] The wiper model affects the size of the wiper blind spot, the degree of dirt in the wiper blind spot and the ambient temperature affect the ease of cleaning the dirt, and the amount of rainfall affects the ease of cleaning the rainwater. Therefore, the blind spot cleaning parameters can be determined based on at least one of the wiper model, ambient temperature, current rainfall and degree of dirt in the wiper blind spot.

[0083] For example, blind spot cleaning data includes wiper model, ambient temperature, and current rainfall. Blind spot cleaning execution parameters include blind spot cleaning range, blind spot cleaning speed, and blind spot cleaning duration. The preset correspondence between cleaning data and execution parameters is the correspondence between wiper model range, ambient temperature range, rainfall range, and cleaning range, cleaning duration, and cleaning speed.

[0084] First, determine the rainfall range to which the current rainfall belongs, the ambient temperature range to which the ambient temperature belongs, and the wiper signal range to which the wiper model belongs. Then, use the cleaning range, cleaning duration, and cleaning speed corresponding to the wiper model range, ambient temperature range, and rainfall range as the blind spot cleaning range, blind spot cleaning duration, and blind spot cleaning speed corresponding to the current rainfall, vehicle data, and environmental data.

[0085] For example, Table 1 shows the correspondence between the range of wiper models, the range of ambient temperature, the range of rainfall provided in this application and the cleaning range, cleaning time, and cleaning speed.

[0086] Table 1

[0087]

[0088]

[0089] As shown in Table 1, the cleaning range consists of two angle values, which are the angles between the wiper blade and the horizontal direction. The blind spot cleaning range is the area formed by the wiper blade moving within these two angle values.

[0090] The cleaning range can also be a distance value and an angle value. The distance value represents the minimum distance between the wiper and the vehicle's A-pillar, and the angle value represents the angle at which the wiper moves. The blind spot cleaning range is the range formed by the wiper moving at that angle value from its starting position, and the distance between the starting position and the vehicle's A-pillar is that distance value.

[0091] For example, a cleaning range of 10 mm and 10 degrees means that the minimum distance between the windshield wiper and the vehicle's A-pillar is 10 mm, and the angle at which the windshield wiper moves is 10 degrees.

[0092] The cleaning range is the range of movement of the wiper when cleaning the blind spot of the wiper. The embodiments of this application do not limit the cleaning range, which can be determined according to the actual situation.

[0093] Because different wiper models create different blind spots, their corresponding cleaning ranges also differ. Higher ambient temperatures make it easier to clean dirt, resulting in shorter cleaning times and slower cleaning speeds. Conversely, heavier rainfall necessitates faster cleaning speeds and longer cleaning times to effectively remove rainwater.

[0094] Table 1 is merely an example of the correspondence between the range of wiper models, the range of ambient temperature, the range of rainfall, and the cleaning range, cleaning time, and cleaning speed. This application embodiment does not limit the correspondence between preset cleaning data and execution parameters, and can be determined according to the actual situation.

[0095] The VCU controls the wipers to continuously wipe within the blind spot cleaning area. The wiping speed for each wipe is the blind spot cleaning speed. Wiping stops after the blind spot cleaning time is up, completing the cleaning process and exiting the blind spot cleaning mode.

[0096] It should be noted that the cleaning range in each mode consists of two arcs and two straight lines. The uppermost line is the upper boundary, and the lowermost line is the lower boundary. The lower boundary of the regular cleaning range is the first lower boundary, and the upper boundary of the regular cleaning range is the first upper boundary. In the blind spot cleaning mode, the lower boundary of the blind spot cleaning range is the second lower boundary, and the upper boundary of the blind spot cleaning range is the second upper boundary.

[0097] It should be noted that the second upper boundary is located between the first upper boundary and the vehicle's A-pillar, and the second lower boundary is located between the first upper boundary and the first lower boundary. This allows the blind spot cleaning range to overlap with the wiper blind spot, enabling the wiper blind spot to be cleaned without colliding with the vehicle's A-pillar.

[0098] In addition, the second lower boundary will not reach the first lower boundary, and the blind spot cleaning range is small. Even if the blind spot cleaning speed is slow, the blind spot cleaning range can be scraped multiple times within the blind spot cleaning time, thus improving cleaning efficiency.

[0099] For example, Figure 2b A schematic diagram of the blind spot cleaning range provided in this application is shown below. Figure 2b As shown, the gray fan-shaped area represents the regular cleaning range, while the fan-shaped area enclosed by the solid black line represents the blind spot cleaning range. The lower boundary of the regular cleaning range is the first lower boundary, and the upper boundary is the first upper boundary. The lower boundary of the blind spot cleaning range is the second lower boundary, and the upper boundary is the second upper boundary. The second upper boundary is located between the first upper boundary and the vehicle's A-pillar, and the second lower boundary is located between the first upper boundary and the first lower boundary.

[0100] It should be noted that the blind spot cleaning speed is lower than the cleaning speed corresponding to the regular cleaning mode. This means that the wipers move at a lower speed and have less inertia within the blind spot cleaning range, reducing the chance of the wipers colliding with the vehicle's A-pillar.

[0101] In the preset correspondence between cleaning data and execution parameters, each cleaning speed is less than the cleaning speed corresponding to the normal cleaning mode, and can be 1 / 4 to 1 / 2 of the cleaning speed corresponding to the normal cleaning mode. This application embodiment does not limit the cleaning speed, and it can be determined according to the actual situation.

[0102] In the preset correspondence between cleaning data and execution parameters, the upper boundary of each cleaning range is located between the first upper boundary and the vehicle's A-pillar, and the lower boundary of the blind spot cleaning range is located between the first upper boundary and the first lower boundary.

[0103] It should be noted that the VCU can obtain the degree of dirt in the wiper blind spot in two ways: First, the driver can send the degree of dirt in the wiper blind spot to the VCU using a terminal device, and the VCU can then obtain the degree of dirt. Second, the VCU can generate and store the degree of dirt in the wiper blind spot, and can retrieve the degree of dirt from the stored data. This application does not limit the method by which the VCU obtains the degree of dirt in the wiper blind spot, and it can be determined according to the actual situation.

[0104] The process by which the VCU generates and stores values ​​indicating the degree of dirt in the wiper blind spot can be as follows:

[0105] The VCU first acquires images of the wiper blind spot, then inputs these images into the object detection model to obtain dirt detection results, including the number of dirt spots in the wiper blind spot. The object detection model is a pre-trained neural network model used to calculate the dirt detection results based on the captured images.

[0106] Then, based on the preset correspondence between the number range of dirt spots and the degree of dirt, the degree of dirt in the wiper blind area corresponding to the number of dirt spots is determined and stored. That is, the range of dirt spots to which the number of dirt spots in the wiper blind area belongs is first determined, and then the degree of dirt corresponding to the range of dirt spots is used as the degree of dirt in the wiper blind area corresponding to the number of dirt spots.

[0107] For example, a dirt count of 1-10 corresponds to a dirt level of 5%; a dirt count of 11-30 corresponds to a dirt level of 10%; a dirt count of 31-100 corresponds to a dirt level of 20%; a dirt count of 101-200 corresponds to a dirt level of 40%; a dirt count of 201-500 corresponds to a dirt level of 60%; a dirt count of 501-600 corresponds to a dirt level of 80%; and a dirt count of 601-1000 corresponds to a dirt level of 90%. This application does not limit the correspondence between the dirt count range and the dirt level value; it can be determined according to the actual situation.

[0108] It should be noted that the VCU can acquire images of the wiper blind spot in several ways: the driver can use a terminal device to take a picture of the blind spot and send it to the VCU, which can then acquire the image. Alternatively, the vehicle can have a camera that can capture images of the wiper blind spot, and the VCU can use this camera to take pictures of the blind spot. This application does not limit the method by which the VCU acquires images of the wiper blind spot; the method can be determined based on the actual situation.

[0109] It should be noted that the dirt detection results may also include dirt type, dirt type, etc. This application embodiment does not limit the dirt detection results, and can be determined according to the actual situation.

[0110] The windshield wiper control method provided in this embodiment controls the wipers to enter a regular cleaning mode to clean the vehicle's windshield when regular cleaning conditions are determined to be met or a regular cleaning command is received. The regular cleaning range corresponding to the regular cleaning mode has a first upper boundary and a first lower boundary; the area between the first upper boundary and the vehicle's A-pillar is the wiper blind spot. When blind spot cleaning conditions are determined to be met or a blind spot cleaning command is received, the wipers are controlled to enter a blind spot cleaning mode to clean part or all of the blind spot; the blind spot cleaning range corresponding to the blind spot cleaning mode has a second upper boundary and a second lower boundary; the second upper boundary is located between the first upper boundary and the vehicle's A-pillar, and the second lower boundary is located between the first upper boundary and the first lower boundary. This solution achieves controlled wiper cleaning of the blind spot by controlling the wipers to clean the wiper blind spot when preset blind spot cleaning conditions are met or a blind spot cleaning command is received.

[0111] The following describes, through Embodiment 2 of the wiper control method provided in this application, the situation where the VCU controls the wipers to enter the fusion cleaning mode.

[0112] If the VCU determines that the conditions for fusion cleaning are met, or receives a fusion cleaning command, it controls the wipers to enter fusion cleaning mode to clean the vehicle's windshield.

[0113] The fusion cleaning mode includes high-speed cleaning, variable-speed cleaning, and low-speed cleaning ranges. The fusion cleaning range is the union of the regular cleaning range and the blind spot cleaning range.

[0114] The lower boundary of the high-speed cleaning range is the first lower boundary. The upper boundary of the high-speed cleaning range and the lower boundary of the variable speed cleaning range are both the second lower boundary. The upper boundary of the variable speed cleaning range and the lower boundary of the low-speed cleaning range are both located between the second lower boundary and the second upper boundary. The upper boundary of the low-speed cleaning range is the second upper boundary.

[0115] For example, Figure 3 A schematic diagram of the fusion cleaning range provided for this application is shown below. Figure 3 As shown, the fusion cleaning range includes a high-speed cleaning range, a variable-speed cleaning range, and a low-speed cleaning range, which are arranged from bottom to top as follows: high-speed cleaning range, variable-speed cleaning range, and low-speed cleaning range.

[0116] The first cleaning speed corresponding to the high-speed cleaning range is greater than the second cleaning speed corresponding to the low-speed cleaning range.

[0117] The variable speed cleaning range corresponds to a cleaning speed that changes from the first cleaning speed to the second cleaning speed, or from the second cleaning speed to the first cleaning speed.

[0118] As the wiper moves upward, it passes through a high-speed cleaning range, a variable-speed cleaning range, and a low-speed cleaning range in sequence. In the high-speed cleaning range, it operates at the first cleaning speed. In the variable-speed cleaning range, the operating speed changes from the first cleaning speed to the second cleaning speed. In the low-speed cleaning range, it operates at the second cleaning speed.

[0119] As the wiper moves downwards, it passes through a low-speed cleaning range, a variable-speed cleaning range, and a high-speed cleaning range in sequence. In the low-speed cleaning range, it operates at the second cleaning speed. In the variable-speed cleaning range, the operating speed changes from the second cleaning speed to the first cleaning speed. In the high-speed cleaning range, it operates at the first cleaning speed.

[0120] In one implementation, the conditions for merging cleaning are: the current rainfall is greater than a preset threshold for rainfall that affects driving, the windshield wipers are in automatic mode, and the left turn signal is on.

[0121] The conditions for fusion cleaning are met, indicating that not turning on the wipers under the current rainfall would affect driving, the VCU can control the operation of the wipers, and the vehicle needs to turn left, so it is necessary to clean the wiper blind spot and the regular cleaning range.

[0122] For example, Figure 4 This is a flowchart illustrating the process of controlling the windshield wipers to enter the blending and cleaning mode provided in this application, as shown below. Figure 4 As shown, the VCU determines that the current rainfall is greater than the preset rainfall threshold affecting driving, the wiper is in automatic mode and the left turn signal is on, and controls the wipers to enter the fusion cleaning mode.

[0123] The VCU can receive the fusion cleaning command in several ways: First, a self-reset button is installed in the vehicle; the driver presses this button, and the VCU receives the fusion cleaning command. Second, a fusion cleaning button is displayed on the vehicle's terminal device screen; the driver clicks this button, and the VCU receives the fusion cleaning command. Third, the vehicle can have multiple switches, including a switch for entering fusion cleaning mode; the user toggles this switch to the correct position, and the VCU receives the fusion cleaning command. Fourth, the user sends the fusion cleaning command to the VCU using a terminal device, and the VCU receives the fusion cleaning command. This application does not limit the method by which the VCU receives the fusion cleaning command; it can be determined according to the actual situation.

[0124] The wiper control method provided in this embodiment controls the wipers to enter the fusion cleaning mode when the fusion cleaning conditions are determined to be met or a fusion cleaning command is received. This mode simultaneously cleans both the regular cleaning range and the blind spot cleaning range, ensuring that rainwater in both the wiper blind spot and the regular cleaning range is removed when the vehicle turns left, thus improving vehicle safety.

[0125] The following describes, through Embodiment 3 of the wiper control method provided in this application, the situation where the VCU controls the wipers to alternately enter the normal cleaning mode and the blind spot cleaning mode.

[0126] If the VCU determines that the alternating cleaning conditions are met, or receives an alternating cleaning command, it controls the wipers to alternate between the regular cleaning mode and the blind spot cleaning mode.

[0127] In one implementation, the alternating cleaning conditions are: the vehicle is detected to be powered on, the windshield wipers are in automatic mode, and the target dirt level is greater than a preset dirt threshold.

[0128] The target level of dirt is defined as the level of dirt in the wiper blind spot and / or the level of dirt in the regular cleaning area.

[0129] The condition for alternating cleaning is met, indicating that the vehicle has just been powered on, the VCU can control the operation of the wipers, and the windshield is relatively dirty, requiring cleaning of the wiper blind spots and the regular cleaning area.

[0130] The VCU can receive the alternating cleaning command in several ways: First, a self-reset button is installed in the vehicle; the driver presses this button, and the VCU receives the alternating cleaning command. Second, an alternating cleaning button is displayed on the vehicle's terminal device screen; the driver clicks this button, and the VCU receives the alternating cleaning command. Third, the vehicle can have multiple switches, including a position for entering alternating cleaning mode; the user switches to this position, and the VCU receives the alternating cleaning command. Fourth, the user sends the alternating cleaning command to the VCU using a terminal device, and the VCU receives the alternating cleaning command. This application does not limit the method by which the VCU receives the alternating cleaning command; it can be determined according to the actual situation.

[0131] The VCU controls the duration of each wiper entering the normal cleaning mode to be the preset normal cleaning duration, and controls the duration of each wiper entering the blind spot cleaning mode to be the blind spot cleaning duration.

[0132] It should be noted that the preset cleaning time in the normal mode can be 10 seconds, 30 seconds, 1 minute, 2 minutes, 3 minutes, etc. This application embodiment does not limit the cleaning time in the normal mode, and it can be determined according to the actual situation.

[0133] The VCU controls the windshield wipers to enter blind spot cleaning mode, which means controlling the wipers to continuously wipe within the blind spot cleaning area. The wiping speed for each wipe is the blind spot cleaning speed. After the blind spot cleaning time is completed, wiping stops, cleaning is finished, and the blind spot cleaning mode is exited.

[0134] The VCU controls the windshield wipers to enter the normal cleaning mode, which means adjusting the wiping frequency of the wipers according to the amount of rain. The heavier the rain, the higher the wiping frequency, and the wipers will wipe at the determined frequency, with each wipe within the normal cleaning range.

[0135] It should be noted that the VCU can obtain the dirt level value of the regular cleaning area in one of the following ways: the driver sends the dirt level value of the regular cleaning area to the VCU using a terminal device, and the VCU can then obtain the dirt level value of the regular cleaning area. Alternatively, the VCU can generate and store the dirt level value of the regular cleaning area, and can obtain the dirt level value of the regular cleaning area from the stored data. This application embodiment does not limit the method by which the VCU obtains the dirt level value of the regular cleaning area, and can determine it according to the actual situation.

[0136] The process by which the VCU generates and stores dirt levels for a typical cleaning range can be:

[0137] The VCU first acquires images of the regular cleaning area, then inputs these images into the object detection model to obtain the dirt detection results, which include the number of dirt spots within the regular cleaning area. The object detection model is a pre-trained neural network model used to calculate the dirt detection results based on the captured images.

[0138] Then, based on the preset correspondence between the number of dirt spots and the degree of dirt, the degree of dirt for the regular cleaning range corresponding to the number of dirt spots is determined and stored. In other words, the range of dirt spots to which the number of dirt spots in the regular cleaning range belongs is first determined, and then the degree of dirt corresponding to that range is used as the degree of dirt for the regular cleaning range.

[0139] It should be noted that the VCU can acquire images of the regular cleaning area in several ways: the driver uses a terminal device to take a picture of the regular cleaning area and sends it to the VCU, which then acquires the image. Alternatively, the vehicle may have a camera capable of capturing images of the regular cleaning area, and the VCU can capture images of the regular cleaning area using this camera. This application does not limit the method by which the VCU acquires images of the regular cleaning area; the method can be determined based on actual circumstances.

[0140] It should be noted that the dirt detection results may also include dirt type, dirt type, etc. This application embodiment does not limit the dirt detection results, and can be determined according to the actual situation.

[0141] The wiper control method provided in this embodiment controls the wipers to alternate between a regular cleaning mode and a blind spot cleaning mode when the alternating cleaning conditions are determined to be met or when an alternating cleaning command is received. This ensures that rainwater and dirt in both the wiper blind spot and the regular cleaning range can be removed, thereby improving vehicle safety.
