Description

Technical Field

[0002] Currently, automatic windshield wiper control relies on rain sensors to measure rainfall intensity and determine the wiper control scheme based on the rainfall level. Rain sensors typically operate on the principle of infrared optical reflection, emitting an infrared beam onto the windshield and determining whether the glass surface is dry (high reflection) or has raindrops (increased scattering) by receiving the intensity of the reflected light. When air pollution is severe and the air quality is poor, dust adhering to the glass or sensor surface can continuously block light, causing system misjudgments and triggering the wipers to activate unnecessarily. Furthermore, in cases of severe air pollution, dust mixed with rainwater can easily form mud, severely obstructing visibility. These problems urgently need to be addressed. Summary of the Invention

[0022] Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] To address the problems existing in the prior art, this application provides a method, system, and vehicle for optimized control of windshield wipers in dusty environments for commercial vehicles.

[0024] A method for optimizing wiper control in dusty environments for commercial vehicles, comprising the following steps: The system acquires data on dust content, rainfall, and real-time environmental images outside the vehicle. Preferably, data is acquired every 100ms, and the wiper control scheme is determined based on the real-time data.

[0025] Real-time air quality index levels are determined based on dust content values. These levels include Excellent, Good, Lightly Polluted, Moderately Polluted, and Heavily Polluted. The air quality index level is determined based on PM2.5 levels: Excellent: PM2.5 < 35 µg / m³ 3 Good: PM2.5 level is 35-75 µg / m³ 3 Light pollution: PM2.5 level is 75-115 µg / m³3 Moderate pollution: PM2.5 level is 115-150 µg / m³ 3 Severe pollution: PM2.5 > 150 µg / m³ 3 .

[0026] Real-time precipitation levels are determined based on rainfall data. Precipitation levels include no rain, light rain, moderate rain, heavy rain, and rainstorm. The rainfall level is determined based on the pulse frequency obtained by the rain sensor: 50Hz≤light rain<80Hz, 80Hz≤moderate rain<150Hz, 150Hz≤heavy rain<250Hz, and rainstorm ≥250Hz. Determine whether it is raining based on real-time environmental images; The wiper control scheme is determined based on air quality index levels, real-time precipitation levels, and real-time environmental images.

[0027] The present invention provides a windshield wiper optimization control method for commercial vehicles in dusty environments. Based on the determination of the wiper control scheme by combining air quality index level, real-time precipitation level and real-time environmental image, it can avoid the wiper malfunction caused by using a rain sensor to obtain the real-time precipitation level. Furthermore, by introducing the air quality index level as an indicator to determine the wiper control scheme, it can ensure that the wipers clean the windshield and maintain driving visibility when the air pollution is severe.

[0028] In some preferred embodiments, the steps of determining the wiper control scheme based on air quality index levels, real-time precipitation levels, and real-time environmental images include: If the air quality index is at any level, the real-time precipitation level is heavy rain or torrential rain, and the real-time weather is rain, then the wiper control scheme is to continuously operate the wipers at high speed or medium-high speed. Preferably, when the precipitation level is heavy rain, the frequency range of the first frequency is 0.8-1.2 Hz, with a preferred frequency of 1.0 Hz, where 1.0 Hz is defined as the wiper completing one reciprocating motion in 1 second. At this time, the wiping speed is 240-300 deg / s (based on a single-journey angle of 120°-150°, the same below). When the precipitation level is torrential rain, the frequency range is 1.3-2.0 Hz, with a preferred frequency of 1.5 Hz. At this time, the wiping speed is 180-225 deg / s. Adopting the above-mentioned first frequency is more in line with the usage scenarios and driving experience. If the wiper speed is too slow (i.e., the frequency is too low), water accumulation on the glass cannot be cleared in time, forming a continuous water film, requiring the driver to frequently manually switch wiper speeds. If the wiper speed is too fast (i.e., the frequency is too high), the motor load increases, causing mechanical wear. For example, high-frequency oscillation (action frequency > 2 Hz) can cause blurred edges of objects, affecting driving visibility and driving safety.

[0029] If the air quality index is rated as excellent, good, or lightly polluted, the real-time precipitation level is heavy rain or torrential rain, and the real-time weather is no rain, then the wiper control scheme will stop the wipers from operating. If the air quality index is moderate or heavy pollution, the real-time precipitation level is heavy rain or torrential rain, and the real-time weather is no rain, then the wiper control scheme is to operate the wipers intermittently, and spray water before or during each operation.

[0030] Preferably, when the wipers operate intermittently, the operating frequency is 1Hz, each operation lasts for 3 seconds, and the interval between two operations is 3-5 seconds, preferably 4 seconds. That is, without continuous wiping, the intermittent operation combined with automatic water spraying can remove dust from the glass surface. Based on this, energy consumption can be saved, wiper wear reduced, and clear and safe driving visibility ensured.

[0031] Preferably, water is sprayed before each wiper action, and the spray area covers the wiper wiping area; this avoids dry wiping caused by asynchronous water spraying and wiper action.

[0032] In some preferred embodiments, the steps of determining the wiper control scheme based on air quality index levels, real-time precipitation levels, and real-time environmental images include: If the air quality index is good or excellent, the real-time precipitation level is moderate rain, and the real-time weather is rain, then the wiper control scheme will have the wipers operate continuously at the second frequency.

[0033] Preferably, the second frequency is 0.5-0.8 Hz, and more preferably 0.7 Hz; at this time, the wiping speed is 168-210 deg / s; thus, it is ensured that rain does not obstruct the driver's view.

[0034] In some preferred embodiments, the steps of determining the wiper control scheme based on air quality index levels, real-time precipitation levels, and real-time environmental images include: If the air quality index is light, moderate, or heavy pollution, the real-time precipitation level is moderate rain, and the real-time weather is rain, then the wiper control scheme is for the wipers to operate continuously at the second frequency, and to spray water before the first operation.

[0035] Preferably, the second frequency is 0.5-0.8 Hz, and more preferably 0.7 Hz; at this time, the wiping speed is 168-210 deg / s; based on this, in conjunction with the water spray operation before the first action, it can avoid the mud deposited on the windshield surface due to high dust content and rain affecting the driver's vision, and the fact that no water spray is sprayed after the first action can avoid the water spray affecting the wipers' ability to remove mud.

[0036] More preferably, the method further includes acquiring real-time images of the windshield, for example, acquiring data every 100ms; detecting whether there are dust-laden areas on the windshield based on the real-time images, such as using Canny edge detection or other existing methods, without limitation; and determining whether to adjust the water spray scheme and wiper frequency based on the detection results. Specifically, if the detection result indicates the presence of dust-laden areas, the water spray frequency is increased to 0.3s per spray, with a 1s interval between sprays, and the wiper frequency is adjusted to 1.5Hz, with a wiping speed of 180-225 deg / s; if the detection result indicates the absence of dust-laden areas, the original control scheme is maintained. This avoids affecting the removal of deposited mud, effectively cleans dust-laden areas, ensures driving visibility and safety, and prevents excessive wear on the wipers. More preferably, the water spraying frequency is in groups of 3, with each spray lasting 0.3 seconds, an interval of 1 second between each spray, and an interval of 3 seconds between each group; thus, water consumption is saved while achieving the same cleaning effect.

[0037] If the air quality index is lightly polluted, the real-time precipitation level is moderate rain, and the real-time weather is no rain, then the wiper control scheme will be to stop the wipers from operating. If the air quality index is moderate or heavy pollution, the real-time precipitation level is moderate rain, and the real-time weather is no rain, then the wiper control scheme is to have the wipers operate intermittently, and to spray water before or during each operation, preferably spraying water before operation.

[0038] Preferably, when the wipers operate intermittently, the operating frequency is 1Hz, each operation lasts for 3 seconds, and the interval between two operations is 3-5 seconds, preferably 4 seconds. That is, without continuous wiping, the intermittent operation combined with automatic water spraying can remove dust from the glass surface. Based on this, energy consumption can be saved, wiper wear reduced, and clear and safe driving visibility ensured.

[0039] In some preferred embodiments, the steps of determining the wiper control scheme based on air quality index levels, real-time precipitation levels, and real-time environmental images include: If the air quality index is good or excellent, the real-time precipitation level is light rain, and the real-time weather is raining, then the wiper control scheme will set the wipers to operate at the third frequency.

[0040] Preferably, the frequency of the third frequency action is such that the interval between the two actions is 5-15 seconds. Within this range, it can ensure that the glass is cleaned and that the noise and wear generated are low; more preferably, the time interval is 10 seconds, the preferred frequency of the action is 0.3 Hz, and the swiping speed is 72-90 deg / s.

[0041] In some preferred embodiments, the steps of determining the wiper control scheme based on air quality index levels, real-time precipitation levels, and real-time environmental images include: If the air quality index is light, moderate, or heavy pollution, the real-time precipitation level is light rain, and the real-time weather is rain, then the wiper control scheme is intermittent wiper operation. Preferably, the interval between two operations is 2-8 seconds, preferably 5 seconds, the preferred operation frequency is 0.5 Hz, and the wiping speed is 120-150 deg / s. Water is sprayed before or during each operation, preferably before. Based on this, high-frequency wiper operation and water spraying with each operation ensure cleaning effect, clear driving visibility, and driving safety. More preferably, it also includes acquiring real-time images of the windshield, for example, acquiring data every 100ms; detecting whether there are dust accumulation areas on the windshield based on the real-time images, and determining whether to adjust the water spray scheme and wiper operation frequency based on the detection results. Specifically, if the test results indicate the presence of dust-laden areas, the water spray frequency is three consecutive sprays, each lasting 0.3 seconds, with a 1-second interval between each spray. Simultaneously, the wiper frequency is adjusted to 1.5Hz, resulting in a wiping speed of 180-225 deg / s. If the test results indicate the absence of dust-laden areas, the original control scheme is maintained. This approach avoids affecting the removal of deposited mud while effectively cleaning dust-laden areas, ensuring driving visibility and safety, and preventing excessive wear on the wipers.

[0042] If the air quality index is lightly polluted, the real-time precipitation level is light rain, and the real-time weather is no rain, then the wiper control scheme is to stop the wipers from operating. If the air quality index is moderate or heavy pollution, the real-time precipitation level is light rain, and the real-time weather is no rain, then the wiper control scheme is to have the wipers operate intermittently, and to spray water before or during each operation, preferably spraying water before operation.

[0043] Preferably, when the wipers operate intermittently, the operating frequency is 1Hz, each operation lasts for 3 seconds, and the interval between two operations is 3-5 seconds, preferably 4 seconds. That is, without continuous wiping, the intermittent operation combined with automatic water spraying can remove dust from the glass surface. Based on this, energy consumption can be saved, wiper wear reduced, and clear and safe driving visibility ensured.

[0044] In some preferred embodiments, the steps of determining the wiper control scheme based on air quality index levels, real-time precipitation levels, and real-time environmental images include: If the air quality index is rated as excellent, good, or lightly polluted, the real-time precipitation level is no rain, and the real-time weather is also no rain, then the wiper control scheme will stop the wipers from operating.

[0045] In some preferred embodiments, the steps of determining the wiper control scheme based on air quality index levels, real-time precipitation levels, and real-time environmental images include: If the air quality index is moderate or heavy pollution, the real-time precipitation level is no rain, and the real-time weather is no rain, then the wiper control scheme is to have the wipers operate intermittently, and to spray water before or during each operation, preferably spraying water before operation. Preferably, when the wipers operate intermittently, the operating frequency is 1Hz, each operation lasts for 3 seconds, and the interval between two operations is 3-5 seconds, preferably 4 seconds. That is, without continuous wiping, the intermittent operation combined with automatic water spraying can remove dust from the glass surface. Based on this, energy consumption can be saved, wiper wear reduced, and clear and safe driving visibility ensured.

[0046] In some preferred embodiments, the system further includes controlling the air conditioning circulation mode and the opening / closing status of the sunroof and side windows based on the air quality index level. Specifically, when the air quality index is at a level of severe pollution, the air conditioning is switched to recirculation mode, and the gaps in the sunroof and side windows are closed.

[0047] In some preferred embodiments, the method further includes: acquiring pulse signals of raindrops falling on the windshield using a rain sensor, filtering the pulse signals to remove signals with pulse frequencies lower than a first threshold, obtaining a filtered signal, and determining the precipitation level based on the frequency of the filtered signal; the first threshold can be selected as 50Hz, or the pulse signal range of dust can be determined experimentally, and the value can be higher than the upper limit of the pulse signal range generated by dust.

[0048] Example 2 This embodiment provides a dust environment wiper optimization control system for commercial vehicles, which includes: The dust content acquisition module is used to acquire the dust content value in the external environment of the vehicle. Rainfall acquisition module, used to acquire rainfall data outside the vehicle; The image acquisition module is used to acquire real-time environmental images outside the vehicle, specifically, it can be acquired using an in-vehicle camera; The first determining module is used to determine the real-time air quality index level based on the dust content value. The air quality index levels include excellent, good, light pollution, moderate pollution and heavy pollution. The second determination module is used to determine the real-time precipitation level based on the rainfall data. The precipitation levels include no rain, light rain, moderate rain, heavy rain, and rainstorm. The third determination module is used to determine whether it is raining in real time based on real-time environmental images. Specifically, existing methods can be selected to determine whether it is raining, such as raindrop detection technology based on visual feature analysis, such as gradient operator and partitioning method, background blurring and multi-frame averaging method, or raindrop lens effect recognition method, etc.

[0049] The fourth determination module is used to determine the wiper control scheme based on the air quality index level, real-time precipitation level, and real-time environmental images.

[0050] The control system of the present invention determines the wiper control scheme based on air quality index level, real-time precipitation level and real-time environmental image. It can avoid the wiper malfunction caused by using a rain sensor to obtain real-time precipitation level. Furthermore, by introducing air quality index level as an indicator to determine the wiper control scheme, it can ensure that the wipers clean the windshield and maintain driving visibility when air pollution is severe.

[0051] In some preferred embodiments, the rainfall acquisition module includes a rainfall sensor and a first filter; The rain sensor can generate a pulse signal when raindrops fall on the windshield; The first filter is used to remove frequencies in the pulse signal that are below a first threshold, thus obtaining a filtered signal. Specifically, the first threshold can be selected as 50Hz, or it can be determined experimentally as the pulse signal range of dust, and be higher than the upper limit of the pulse signal range generated by dust.

[0052] In some preferred embodiments, a controller is also included, which controls whether water is sprayed and the frequency of water spraying, as well as the start and stop of the wipers and their operating frequency.

[0053] In some preferred embodiments, the system further includes a real-time image acquisition module for the windshield, a determination module, and a controller. The image acquisition module is used to acquire real-time images of the windshield, for example, acquiring data once every 100ms. The determination module is used to detect whether there are dust-laden areas on the windshield based on real-time images of the windshield. The controller determines whether to adjust the water spray pattern and wiper frequency based on the detection results from the judgment module. Specifically, if the detection result indicates the presence of dust accumulation areas, the water spray frequency is increased to 0.3 seconds per spray, with a 1-second interval between sprays. Simultaneously, the wiper frequency is adjusted to 1.5Hz, with a wiping speed of 180-225 deg / s. If the detection result indicates the absence of dust accumulation areas, the original control scheme is maintained. This approach avoids affecting the removal of deposited mud while effectively cleaning dust accumulation areas, ensuring driving visibility and safety, and preventing excessive wear on the wipers.

[0054] Specifically, the image acquisition module can be an in-vehicle camera, and the controller can be the vehicle's BCM controller. A camera identifies localized dust accumulation areas on the windshield. A chip within the camera housing enables image acquisition and signal transmission / reception via the bus. Alternatively, an external camera can be connected to the ECU. The camera acquires signals and transmits them to the ECU, which then transmits signals on the bus. The chip or ECU determines the presence of dust accumulation areas and generates a detection status signal, which is transmitted to the bus network. Upon receiving this signal, the BCM controller sends washer fluid and wiper operation commands to the bus. The washer fluid controller receives this signal in real-time and initiates or stops washer fluid spraying. If a dust accumulation area is detected, this signal is transmitted to the bus. Upon receiving this signal, the actuator in the washer fluid controller begins automatic cyclic spraying (0.3 s / cycle, 1 s interval). The wiper controller controls the wipers to operate at the highest frequency (preferably 1.5 Hz, wiping speed 180-225 deg / s). Once the dust accumulation area signal is cleared, the original wiper control scheme resumes.
