[0002] With the rapid development of intelligent vehicles, the use of automatic wipers in automobiles has become increasingly popular. During the driving of a vehicle, such as in rainy weather, the amount of rain continuously falling on the windshield can be sensed by a sensor, and then the wiper controller can control the wiper motor to drive the wiper to move according to the continuously changing amount of rain.

[0040] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given with reference to the accompanying drawings.

[0041] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here.

[0042] In the description of this specification, the descriptions referring to the terms "embodiment", "an embodiment" and "an implementation manner", etc. mean that the specific features, structures, materials or characteristics described in connection with the embodiment or implementation manner are included in at least one embodiment or implementation manner of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or implementation manner. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementation manners in a suitable manner.

[0043] Figure 1 Shows a schematic flowchart of a windshield wiper control method in an embodiment of the present invention. Based on a sensor assembly, the sensor assembly is installed at the windshield, and the sensor assembly includes a light emitter and a light receiver. The windshield wiper control method includes:

[0044] S1: When the vehicle is powered on, obtain the amount of light received by the light receiver, wherein the light emitter emits light onto the windshield, and the light receiver receives the light reflected by the windshield.

[0045] Specifically, with the development of intelligent vehicles, many vehicles can be powered on and standby without inserting the key into the vehicle keyhole. Through the electronic key or Bluetooth key, the vehicle can be powered on in advance before getting in the car. After the vehicle is powered on, various components and electronic devices are energized. Additionally, if the control switch of the windshield wiper is in the automatic gear, an automatic signal will be actively fed back to enable the windshield wiper controller to constantly monitor whether there is rain on the windshield; when the control switch of the windshield wiper is in the manual gear, each time the user toggles the control switch, the windshield wiper will scrape one or several cycles accordingly. Since both the light emitter and the light receiver are already energized, the light receiver receives the light emitted by the light emitter and reflected by the windshield. As Figure 2 shown, exemplarily, two transmitting LEDs (i.e., light emitters) are symmetrically arranged on both sides of the receiving LED (i.e., light receiver), which can increase the monitoring range. The amount of light received by the receiving LED can be the sum of the light emitted and reflected by the two transmitting LEDs, or the amount of light emitted and reflected by a single transmitting LED alone. Figure 2 In, a layer of silicone is attached to the inner wall of the windshield. The silicone plays an important role in ensuring sealing and waterproofing, shock absorption and noise reduction, fixing and supporting, and preventing crack propagation. The silicone on the windshield is usually a transparent or semi-transparent material, and its main component is a siloxane compound. The silicone has good optical transparency and can allow light to pass through without significant scattering or absorption. When light shines on the silicone on the windshield, most of the light will penetrate the silicone and continue to propagate towards the glass surface. Only a small amount of light will be absorbed or scattered by the silicone, but this has little impact on the overall light reflection effect and thus will not significantly affect the light reflection.

[0046] S2: When the amount of light exceeds the preset standard light amount range, drive the windshield wiper to act, and drive the windshield wiper to scrape a preset number of times by controlling the windshield wiper drive motor.

[0047] Specifically, the preset standard light amount range is the light amount range received by the light receiver when there are no water droplets on the windshield. The preset standard light amount range is set because the standard light amount fluctuates to some extent due to the influence of dust on the windshield. When there is only one light emitter, it can be determined whether the amount of light received by the light receiver is within the preset standard light amount range. When it is within the preset standard light amount range, it indicates that the reflected light is not interfered, indicating that the windshield is clean and there are no water droplets; otherwise, the reflected light is refracted by the water droplets. When there are multiple light emitters, if multiple light emitters work simultaneously, the amount of light received by the light receiver is the sum of the light stably emitted by multiple light emitters and reflected by the windshield. As Figure 2As shown, two symmetric light - emitting LEDs are arranged on both sides of the light - receiving LED. When there are no water droplets on the glass, the light emitted by the two side - emitting LEDs is reflected by the glass and then received by the receiving LED, and the amount of received light is within the preset standard light - amount range. As Figure 3 shown, when there are water droplets on the glass, the reflection of light is affected, and some light is refracted by the water droplets, causing the amount of light received by the receiving LED to exceed the preset standard light - amount range. For the analysis of the light amount, the two side - emitting LEDs can be controlled separately to be alternately powered on, so that the receiving LED can separately identify the amount of reflected light on both sides; the receiving LED can include multiple LEDs. At this time, the receiving LED can be partitioned into a left - half region and a right - half region. The left - half region can only receive the light emitted by the left - side emitting LED, and the right - half region can only receive the light emitted by the right - side emitting LED. In this way, the reflected light on both sides can be separately identified to obtain the amount of received light, and the reflection situation of the light emitted by each emitting LED can be analyzed separately, which is beneficial to accurately analyze the position of the water droplet.

[0048] Specifically, when the light amount exceeds the preset standard light - amount range, it indicates that there are water droplets on the windshield. Regardless of whether the water droplets change continuously or not, the windshield wiper is immediately driven to move to quickly clean the water droplets on the windshield once. It is also possible to precisely control the driving of the wiper when the user gets into the driver's seat. At this time, the wiper is controlled to clean the water droplets in the driving vision in time to ensure a clear vision. In addition, whether the user gets into the car or not can be monitored from multiple directions. When the driver's - seat door is opened, it can be regarded that the user is about to get into the car, and the light amount can be analyzed; the user's getting - into - car behavior can also be monitored through aspects such as the pressure on the driver's - seat and the buckling of the driver's - seat seat belt.

[0049] In this embodiment, if the vehicle is parked in an open area, after rain for example, there will be water droplets remaining on the windshield. When the driver gets in the vehicle and powers on, the sensor assembly installed at the windshield can start to work. At this time, the windshield wiper is usually in the automatic gear. Among them, the light emitter emits light onto the windshield, and after emission, it is received by the light receiver. The amount of light received by the light receiver is analyzed to determine whether the amount of light is within the preset standard light amount range or exceeds this range. When it exceeds this range, it indicates that there are water droplets on the windshield. At this time, the windshield wiper can be immediately driven to act. For example, a trigger signal is sent to the windshield wiper drive motor to control the windshield wiper drive motor to drive the windshield wiper to scrape a preset number of times, such as scraping 1 - 2 cycles, so as to remove the remaining water droplets on the windshield, ensuring the driver's driving vision, which can not only improve the user experience, but also ensure driving safety to a certain extent. As long as there are water droplets on the windshield, a trigger signal is immediately sent to the windshield wiper motor when the user enters the vehicle driver's seat to control the windshield wiper to scrape, improving the sensitivity and reaction speed of the windshield wiper control, avoiding the situation where there are water droplets but the windshield wiper does not scrape when the user gets in the vehicle, and enhancing the user's vehicle use experience.

[0050] In an embodiment of the present invention, as Figure 2 , after driving the windshield wiper to act when the amount of light exceeds the preset standard light amount range, the windshield wiper control method further includes:

[0051] S3: Continuously obtain the amount of light at different time points.

[0052] Specifically, the intervals between multiple time points can be unequal. However, for the convenience of control and analysis, multiple time points can be set as equally spaced time points. The determination method of multiple time points is to determine the positions of multiple time points according to the set interval starting from the moment when the trigger signal is sent, and then start to collect the amount of light at multiple time points, and complete the data collection at multiple time points within a few seconds after the trigger signal is sent. On the one hand, it does not affect the generation and sending speed of the trigger signal, and on the other hand, it can also ensure the timeliness of subsequent analysis.

[0053] S4: Determine the change amount of the amount of light according to different amounts of light.

[0054] Specifically, in order to further control the subsequent movement mode of the windshield wiper, it is necessary to analyze whether the water droplets on the glass are static or continuously changing. By analyzing whether the amount of light at multiple consecutive time points changes and the amount of change, it is further identified whether it is raining currently. The change amount can be the total sum of the light amount differences obtained by subtracting the light amounts at adjacent time points; it can also be the difference between the maximum light amount and the minimum light amount, etc.

[0055] S5: Switch the scraping mode of the windshield wiper according to the change amount.

[0056] Specifically, if it is currently raining, after controlling the windshield wiper to perform 1-2 wiping cycles, it is also necessary to continue to control the windshield wiper to move continuously or intermittently to facilitate timely cleaning of the rainwater on the windshield. If it is not currently raining, that is, the amount of water droplets on the windshield remains unchanged, only a short startup of the windshield wiper needs to be controlled.

[0057] In an embodiment of the present invention, as Figure 2 , switching the wiping mode of the windshield wiper according to the change amount and the light amount includes:

[0058] S50: Determine whether the change amount is greater than a preset threshold, and the preset threshold at this time is used to determine whether it is currently raining.

[0059] S51: When the change amount is less than or equal to the preset threshold, it means that within a certain period of time, the water droplets on the windshield have no obvious change and can be regarded as unchanged. It is determined that the number of obstacles or interfering objects is water droplets with a constant quantity, and no additional instructions are generated. The windshield wiper is driven to complete the current action, that is, the windshield wiper performs 1-2 wiping cycles.

[0060] S52: When the change amount is greater than the preset threshold, it means that the number of water droplets on the windshield changes greatly, and it may be a rainy day. At this time, it can be determined that the number of obstacles is water droplets with a continuously changing quantity. According to the preset light amount level where the light amount is located, the windshield wiper is driven to perform a corresponding wiping mode, where different preset light amount levels correspond to different wiping modes. The wiping modes include a continuous wiping mode and a continuous intermittent wiping mode, etc. For example, when the light amount is in the first preset light amount level, the windshield wiper is controlled to perform a continuous wiping mode. When the light amount is in the second preset light amount level, the windshield wiper is controlled to perform a continuous intermittent wiping mode. The change amount can also be further analyzed to analyze the current rainfall amount, and then a variety of combined controls can be performed on the speed and wiping mode of the windshield wiper.

[0061] In an embodiment of the present invention, when the light amount exceeds the preset standard light amount range, driving the windshield wiper to act includes:

[0062] When it is detected that the vehicle is vibrating at a preset level and the light amount exceeds the preset standard light amount range, analyze whether the light amount changes.

[0063] Specifically, due to the stable state of solid obstructions, such as mud spots, when the vehicle experiences slight vibrations, the mud spots or scratches will not shake, but water droplets will shake with the vibrations of the vehicle. The shaking water droplets will affect the amount of light, resulting in fluctuations in the light quantity. Based on this characteristic, the type of obstruction can also be analyzed. Instead of monitoring whether the vehicle vibrates, it is possible to monitor whether the user gets into the vehicle. On the one hand, the windshield wiper is controlled only when the user gets into the driver's seat. At this time, the windshield wiper is controlled to ensure a clear driving view. On the other hand, it is to find the timing when the vehicle will vibrate because only when the vehicle drives the water droplets to vibrate will the amount of light reflected by the light change.

[0064] When the light quantity changes, it is determined that the obstruction on the windshield is a water droplet, and the trigger signal is sent to the windshield wiper drive motor to drive the windshield wiper to operate.

[0065] Specifically, when the light quantity changes, it indicates that when the vehicle vibrates slightly, the obstruction is an easily shaken obstruction, most likely a water droplet. Therefore, it is determined that the obstruction on the windshield is a water droplet. To put it another way, even if the obstruction at this time is not a water droplet, but when the vehicle vibrates slightly and the light quantity changes, it indicates that the texture of the obstruction is light and its adhesion to the windshield is not strong, and it is easy to move. Therefore, even if the windshield wiper is activated at this time, it will not cause damage to the windshield, and it can also smoothly remove foreign objects, which is beneficial to cleaning the obstructions within the driver's field of vision. When the light quantity does not change, it indicates that when the vehicle vibrates slightly, the obstruction does not change, indicating that the obstruction is a solid obstruction, which may be obstructions such as mud spots and scratches. Then it is determined that the obstruction on the windshield is not a water droplet, and the windshield wiper is kept stationary.

[0066] In an embodiment of the present invention, when it is monitored that the vehicle is in a vibration of a preset degree and the light quantity exceeds the preset standard light quantity range, analyzing whether the light quantity changes includes:

[0067] When it is monitored that the vehicle is in a vibration of a preset degree and the light quantity exceeds the preset standard light quantity range, analyze whether the light quantity at the current moment is within the fluctuation range of the light quantity at the previous moment.

[0068] Specifically, before the user enters the driver's seat, the vehicle is in a parked state, the vehicle does not vibrate, and the light quantity remains almost unchanged. However, when the user gets into the vehicle, a series of actions such as opening the door, getting into the vehicle, and closing the door are usually required, which will generally cause the vehicle to shake. At this time, if there are water droplets on the windshield, they will generally shake, which will cause a change in the amount of light received by the light receiver.

[0069] When the light quantity at the current moment is within the fluctuation range of the light quantity at the previous moment, it is determined that the light quantity does not change, indicating that the vehicle shake has no effect on the obstruction.

[0070] When the light quantity at the current moment exceeds the fluctuation range of the light quantity at the previous moment, it is determined that the light quantity has changed, indicating that the vibration of the vehicle causes a change in the shape of the obstacle.

[0071] In this embodiment, a fluctuation range is formed based on the light quantity at the previous moment. For example, a fluctuation range is formed by floating up and down 5% based on the light quantity at the previous moment; the fluctuation range is much smaller than the preset threshold corresponding to the above change amount.

[0072] In an embodiment of the present invention, when the light quantity exceeds the preset standard light quantity range, driving the wiper to operate includes:

[0073] When the light quantity exceeds the preset standard light quantity range, analyze the range where the light quantity is located, where the range includes a first range and a second range.

[0074] Specifically, since the influence of solid foreign objects such as leaves and water droplets on the reflected light is different, a first range of the light quantity caused by foreign objects and a second range of the light quantity caused by water droplets can be set in advance. According to the range where the light quantity is located, identify the type of obstacle on the windshield.

[0075] When the light quantity is within the first range, it is determined that the obstacle on the windshield is not a water droplet, and the wiper remains stationary.

[0076] When the light quantity is within the second range, it is determined that the obstacle on the windshield is a water droplet. When vehicle vibration is detected, drive the wiper to operate.

[0077] In this embodiment, the type of the obstacle is further analyzed to determine whether the obstacle is a water droplet. Only when the obstacle is a water droplet, immediately control the wiper to start, so as to clean the water droplets that may affect the line of sight in time. However, when the obstacle is not a water droplet, keep the wiper stationary to avoid the wiper starting incorrectly and scratching the front windshield.

[0078] In an embodiment of the present invention, as Figure 1 , after determining whether the light quantity is equal to the standard light quantity, the wiper control method further includes:

[0079] When the light quantity is within the preset standard light quantity range, it indicates that there is no water droplet on the windshield. At this time, keep the wiper stationary and do not perform any subsequent analysis, saving analysis resources and reducing energy consumption.

[0080] Figure 5The schematic structural diagram of a windshield wiper control system according to an embodiment of the present invention is shown. Based on a sensor assembly, the sensor assembly is installed at the windshield, and the sensor assembly includes a light emitter and a light receiver. The windshield wiper control system includes:

[0081] A light quantity acquisition module 10, configured to obtain the light quantity received by the light receiver when the vehicle is powered on. Wherein, the light emitter emits light onto the windshield, and the light receiver receives the light reflected by the windshield;

[0082] A windshield wiper control module 20, configured to drive the windshield wiper to operate when the light quantity exceeds a preset standard light quantity range.

[0083] In this embodiment, when the vehicle is powered on and the control switch of the windshield wiper is turned to the automatic gear, the light emitter and the light receiver start to work. The light emitter emits light onto the windshield, and after emission, it is received by the light receiver. The light receiver sends the received light quantity to the light quantity acquisition module 10. The windshield wiper control module 20 analyzes the light quantity received by the light receiver to determine whether the light quantity is within the preset standard light quantity range. When it exceeds this range, it indicates that there are water droplets on the windshield. At this time, the windshield wiper can be immediately driven to operate, and a trigger signal is sent to the windshield wiper drive motor to control the windshield wiper drive motor to drive the windshield wiper to scrape a preset number of times, such as controlling the windshield wiper to briefly scrape 1-2 cycles, so as to remove the residual water droplets on the windshield, ensure the driving vision of the driver, and improve the user experience. As long as there are water droplets on the windshield, a trigger signal is immediately sent to the windshield wiper motor when the user enters the driver's seat of the vehicle to control the windshield wiper to scrape, improving the sensitivity and response speed of the windshield wiper control, avoiding the situation that the windshield wiper does not scrape when there are water droplets when the user gets in the car, and enhancing the user's vehicle use experience.
