[0052] Figure 5 A structural block diagram of an electronic device for windshield wiper control is shown according to an exemplary embodiment. Detailed Implementation

[0053] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] Reference Figure 1 The diagram illustrates a flowchart of a wiper control method according to an embodiment of the present invention, which may specifically include the following steps:

[0055] Step 101: Obtain current rainfall information and current light intensity information of the external environment.

[0056] In this embodiment of the invention, the windshield wipers include, but are not limited to, those of vehicles, aircraft, ships, etc., and this embodiment of the invention does not impose any restrictions on them.

[0057] In this embodiment of the invention, the current rainfall information refers to information reflecting the current rainfall amount. Specifically, it can be obtained by using a rain light sensor to collect light signals and determining the current rainfall information based on the light signals, or by using a camera to collect real-time images and identifying the current rainfall information based on the real-time images, or by detecting the intensity of rain sounds hitting vehicles and determining the current rainfall information based on the rain sound intensity, or any other applicable implementation method. This embodiment of the invention does not limit this.

[0058] In this embodiment of the invention, the current light intensity information of the external environment refers to information reflecting the intensity of the current light in the external environment. Specifically, it can be obtained by using a rain and light sensor to collect light signals and determine the current light intensity information based on the light signals, or by using a camera to collect real-time images and identify the current light intensity information based on the real-time images, or by using a light sensor to determine the current light intensity information, or any other applicable implementation method. This embodiment of the invention does not limit this.

[0059] The Rain Light Sensor (RLS) monitors the amount of rainwater on the windshield. It's a sensor that monitors lighting conditions and provides control signals to the electrical system through circuit calculations. The RLS measures a relative quantity. When the glass surface is dry, it assumes that light emitted from the transmitter is parallel to the windshield, is 100% reflected back, and is then focused by optical elements and received by the receiver. When the windshield's outer surface is dry, the sensor is first initialized to determine the received light intensity under a fixed emission current. In this case, the light intensity is typically high. When there are raindrops on the windshield, some of the incident light is scattered, resulting in less reflected light reaching the receiver; the heavier the rain, the less light is reflected back. By comparing the received light intensity with that when the windshield is dry, the size and amount of water droplets on the windshield can be determined. This allows for the assessment of different rainfall levels, triggering a wiper request to the vehicle's control system or an independent controller, which then controls the wipers to perform intermittent wiping, low-speed continuous wiping, or high-speed continuous wiping.

[0060] There are various ways to identify current rainfall or light intensity information from real-time images. For example, the pre-trained recognition model can be a model obtained through deep learning, such as a CNN (Convolutional Neural Network) or other deep neural networks. It can be trained to predict current rainfall or light intensity information by performing labeled supervised learning on a large number of image samples of scenes with different rainfall or light intensities.

[0061] Step 102: Based on the current light intensity information, determine the control configuration information related to the sensitivity of the windshield wipers; wherein, when the light intensity represented by the current light intensity information is lower than the preset light intensity, the control configuration information corresponding to low sensitivity is adjusted to the control configuration information corresponding to high sensitivity.

[0062] In this embodiment of the invention, when controlling the windshield wipers, control configuration information related to the sensitivity of the wipers is provided. This control configuration information is the configuration information for controlling the sensitivity of the windshield wipers. This control configuration information can be the control configuration information within the rain and light sensor, or the control configuration information within the domain controller controlling the windshield wipers. Specifically, it can be any applicable configuration information, and this embodiment of the invention does not impose any limitations on it. For example, the control configuration information includes a wiping threshold and / or a rainfall coefficient. A higher wiping threshold results in lower wiper sensitivity, and a lower wiping threshold results in higher wiper sensitivity. Similarly, a higher rainfall coefficient results in higher wiper sensitivity, and a lower rainfall coefficient results in lower wiper sensitivity.

[0063] In this embodiment of the invention, the control configuration information is adjusted based on the current light intensity information to determine the control configuration information corresponding to the current light intensity information. The specific implementation of determining the control configuration information related to the sensitivity of the windshield wiper based on the current light intensity information can include various methods. However, regardless of the implementation method, as long as it ensures that: when the light intensity represented by the current light intensity information is lower than a preset light intensity, the control configuration information corresponding to low sensitivity is adjusted to the control configuration information corresponding to high sensitivity, any applicable implementation method can be adopted, and this embodiment of the invention does not impose any restrictions on this.

[0064] For example, the light intensity represented by the current light intensity information is negatively correlated with the sensitivity of the windshield wipers. By using a functional relationship or correspondence table between light intensity information and control configuration information, the corresponding control configuration information is determined based on the current light intensity information. This allows the control configuration information to be adjusted from the low-sensitivity setting to the high-sensitivity setting when the light intensity represented by the current light intensity information is lower than a preset light intensity. Of course, the control configuration information can also change accordingly when the light intensity represented by the current light intensity information changes within a range above or below the preset light intensity.

[0065] For example, based on actual needs, a suitable preset light intensity, as well as suitable control configuration information corresponding to low sensitivity and suitable control configuration information corresponding to high sensitivity can be preset. When the light intensity represented by the current light intensity information is above the preset light intensity, the control configuration information corresponding to low sensitivity is set; when the light intensity represented by the current light intensity information is below the preset light intensity, the control configuration information corresponding to high sensitivity is set.

[0066] Step 103: Control the windshield wipers to operate based on the current rainfall information and the control configuration information.

[0067] In this embodiment of the invention, the windshield wipers are controlled based on current rainfall information and control configuration information, specifically including controlling the on / off state of the wipers and controlling their wiping speed. The specific implementation methods for controlling the windshield wipers to operate based on the current rainfall information and the control configuration information can include various approaches, and this embodiment of the invention does not impose any limitations on these methods.

[0068] For example, the control configuration information includes a wiper activation threshold. When the current rainfall is higher than the wiper activation threshold, the wipers are controlled to start wiping, and when the current rainfall is lower than the wiper activation threshold, the wipers are controlled to stop wiping.

[0069] For example, the control configuration information includes a rainfall coefficient. The product of the current rainfall information and the rainfall coefficient is calculated, and the operation of the windshield wipers is controlled according to the product. For example, when the product is higher than the wiping threshold, the windshield wipers are controlled to start wiping, and when the product is lower than the wiping threshold, the windshield wipers are controlled to stop wiping. The wiping speed of the windshield wipers can also be controlled according to the product.

[0070] According to an embodiment of the present invention, by acquiring current rainfall information and current light intensity information of the external environment, control configuration information related to the sensitivity of the windshield wipers is determined based on the current light intensity information. Specifically, when the light intensity represented by the current light intensity information is lower than a preset light intensity, the control configuration information corresponding to low sensitivity is adjusted to the control configuration information corresponding to high sensitivity. Based on the current rainfall information and the control configuration information, the windshield wipers are controlled to operate, thereby automatically increasing the sensitivity of the windshield wipers in dimly lit environments with low light intensity, especially at night, improving the timeliness of the wiper operation, avoiding insufficient driver visibility, and reducing the risk to driving safety.

[0071] In one optional embodiment of the present invention, a specific implementation of obtaining current rainfall information and current light intensity information of the external environment may include: using a rainfall light sensor to collect light signals; and determining the current rainfall information and the current light intensity information based on the light signals.

[0072] The rainfall and light sensor can collect light signals. The light signals are then processed by a circuit to convert them into current rainfall information and current light intensity information. The specific implementation for determining the current rainfall information can refer to the description in the foregoing embodiments, or any other applicable implementation method; this embodiment of the invention does not limit this.

[0073] For example, such as Figure 2 The diagram illustrates the principle of using a rain and light sensor to control windshield wipers. The rain and light sensor internally determines the current rainfall and light intensity information. Based on the light intensity information, it determines the corresponding control configuration information. Then, based on the rainfall and control configuration information, it sends a wiper operation request to the XCU (X Control Unit) via the LIN (Local Interconnect Network) bus and receives control commands from the XCU. The domain controller can also receive control commands from the automatic wiper switch. When the automatic wiper switch is active, the domain controller can control the wiper motor according to the aforementioned wiper operation request, thereby controlling the wiper operation.

[0074] This invention proposes determining the current light intensity information based on the light signal collected by a rain gauge light sensor. The rain gauge light sensor receives not only the light signal emitted from its transmitter but also scattered light from the external environment. Therefore, when the intensity of scattered light in the external environment changes, the intensity of the light signal received by the rain gauge light sensor also changes. Thus, the light signal collected by the rain gauge light sensor can reflect the light intensity of the external environment. Through experiments, the correspondence between the intensity of the light signal and the light intensity of the external environment can be determined. Then, the current light intensity information can be determined based on the real-time received light signal. This method determines the current light intensity information without incurring additional resource consumption, reducing the cost of determining the current light intensity information. Furthermore, it eliminates the need to transmit the current light intensity information from other electronic devices, reducing the complexity of circuit design.

[0075] In an optional embodiment of the present invention, the current rainfall information is a cumulative rainfall value. A specific implementation of determining the current rainfall information based on the light signal may include: determining a rainfall fluctuation value based on the light signal; and determining the cumulative rainfall value based on a rainfall fluctuation value that exceeds a preset no-rain range.

[0076] The light signal collected by the rain gauge is a fluctuating signal. This fluctuation is converted into a fluctuating value, which is recorded as the rain fluctuation value. In dry conditions, the rain fluctuation value generally varies within a preset dry range. Rainfall is only recorded when the rain fluctuation value exceeds this preset range, and the amount of rainfall is recorded based on the fluctuation value exceeding the preset dry range. This accumulated rainfall value is then used as the current rainfall information.

[0077] For example, the rain gauge sensor internally sets a rainfall fluctuation value Z±y when there is no rain. When the rainfall fluctuation value exceeds the upper or lower limit of the preset no-rain range, the rain gauge sensor records the rainfall as valid and determines the cumulative rainfall value K.

[0078] In one optional embodiment of the present invention, a specific implementation of obtaining current rainfall information and current light intensity information of the external environment may include: using a rainfall and light sensor to determine the current rainfall information; acquiring a real-time image of the external environment captured by a camera; and identifying the current light intensity information based on the real-time image.

[0079] The specific implementation method for determining the current rainfall information using a rain gauge and light sensor can be found in the description of the foregoing embodiments. The specific implementation method for identifying the current light intensity information based on real-time images can also be found in the description of the foregoing embodiments, and will not be repeated here.

[0080] Current rainfall and light intensity information are determined by information collected by a rain and light sensor and a camera, respectively. Since the information sources for current rainfall and light intensity are different devices, the camera can still be used to adjust the control configuration information even if the rain and light sensor malfunctions or is affected by other factors. Similarly, the rain and light sensor can still be used to determine the current rainfall information even if the camera malfunctions or is affected by other factors. This reduces the possibility of affecting the normal operation of the windshield wipers and thus improves the stability of the windshield wiper operation.

[0081] Reference Figure 3 The diagram illustrates a flowchart of a wiper control method according to an embodiment of the present invention, which may specifically include the following steps:

[0082] Step 201: Obtain current rainfall information and current light intensity information of the external environment.

[0083] In this embodiment of the invention, the specific implementation of this step can be found in the description of the foregoing embodiments, and will not be repeated here.

[0084] Step 202: Determine the corresponding shaving threshold and / or rainfall coefficient based on the current light intensity information; wherein, when the light intensity represented by the current light intensity information is lower than the preset light intensity, the shaving threshold is lowered and / or the rainfall coefficient is increased.

[0085] In this embodiment of the invention, the control configuration information includes a wiper activation threshold and / or a rainfall coefficient. Lowering the wiper activation threshold can improve the sensitivity of the wipers, while raising the wiper activation threshold can reduce the sensitivity of the wipers. Raising the rainfall coefficient can improve the sensitivity of the wipers, while lowering the rainfall coefficient can reduce the sensitivity of the wipers.

[0086] In this embodiment of the invention, the windshield wipers can have different speed settings. The wiping threshold and / or rainfall coefficient are also different at different speed settings. When adjusting the wiping threshold and / or rainfall coefficient, it is necessary to adjust the wiping threshold and / or rainfall coefficient corresponding to each speed setting. Therefore, when the light intensity represented by the current light intensity information is lower than the preset light intensity, the wiping threshold is lowered and / or the rainfall coefficient is increased for each speed setting of the windshield wipers.

[0087] In one implementation of this invention, a corresponding scratching threshold is determined based on the current light intensity information. When the light intensity represented by the current light intensity information is lower than a preset light intensity, the scratching threshold is lowered. Any applicable implementation method can be used, and this invention does not limit this.

[0088] In one implementation of this invention, a corresponding rainfall coefficient is determined based on the current light intensity information. When the light intensity represented by the current light intensity information is lower than a preset light intensity, the rainfall coefficient is increased. Any applicable implementation method can be used, and this invention does not limit this.

[0089] In one implementation of this invention, a corresponding shaving threshold and rainfall coefficient are determined based on the current light intensity information. When the light intensity represented by the current light intensity information is lower than a preset light intensity, the shaving threshold is lowered and the rainfall coefficient is increased. Any applicable implementation method can be used, and this invention does not limit this.

[0090] Step 203: Calculate the product of the current rainfall information and the rainfall coefficient as the corrected rainfall.

[0091] In this embodiment of the invention, the product of the current rainfall information and the rainfall coefficient is calculated, and the product is used as the corrected rainfall.

[0092] Step 204: When the corrected rainfall reaches the wiper activation threshold, control the wipers to start wiping.

[0093] In this embodiment of the invention, it is determined whether the corrected rainfall amount has reached the wiping threshold. If the corrected rainfall amount reaches the wiping threshold, the wipers are controlled to start wiping; if the corrected rainfall amount has not reached the wiping threshold, the wipers are controlled to stop wiping.

[0094] For example, a windshield wiper can have two sensitivity settings: low sensitivity and high sensitivity, selectable by the driver's license. A threshold value N is set for low sensitivity, and a threshold value O is set for high sensitivity. During the day (when ambient light intensity > βLux), the rainfall coefficient for the low sensitivity threshold value N is L1, and for the high sensitivity threshold value O, it is L2. At night (when ambient light intensity ≤ βLux), the rainfall coefficient for the low sensitivity threshold value N is L3, and for the high sensitivity threshold value O, it is L4. That is, the threshold value remains constant as light intensity changes, but the rainfall coefficient is adjusted. Furthermore, L1 < L3, L2 < L4, thus increasing the rainfall coefficient at night makes the wiper more sensitive.

[0095] In one optional embodiment of the present invention, a specific implementation of controlling the wiping action of the windshield wipers may include: controlling the wiping speed of the windshield wipers according to the corrected rainfall.

[0096] The wiping speed of windshield wipers is generally related to the amount of rainfall. Heavier rainfall typically results in faster wiping speeds, while lighter rainfall generally leads to slower wiping speeds. By adjusting the wiping speed according to the rainfall, the wiper speed can be increased in low-light environments, especially at night, to achieve the same level of wiping speed as in brighter environments. This increases the wiper's workload, thereby preventing insufficient driver visibility and reducing driving safety risks.

[0097] According to an embodiment of the present invention, by acquiring current rainfall information and current light intensity information of the external environment, a corresponding wiper activation threshold and / or rainfall coefficient are determined based on the current light intensity information. Specifically, when the light intensity represented by the current light intensity information is lower than a preset light intensity, the wiper activation threshold is lowered, and / or the rainfall coefficient is increased. The product of the current rainfall information and the rainfall coefficient is calculated as a corrected rainfall amount. When the corrected rainfall amount reaches the wiper activation threshold, the wipers are controlled to operate. This automatically increases the sensitivity of the wipers in dimly lit environments with low light intensity, especially at night, improving the timeliness of wiper operation, avoiding insufficient driver visibility, and reducing the risk to driving safety.

[0098] It should be noted that, for the sake of simplicity, the method embodiments are all described as a series of actions. However, those skilled in the art should understand that the embodiments of the present invention are not limited to the described order of actions, because according to the embodiments of the present invention, some steps can be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions involved are not necessarily essential to the embodiments of the present invention.
