[0016] By setting a rainstorm mode, the wiper control system can control the wiper to wipe the windshield at a safe frequency in a key area. This means high-frequency wiping in a narrow wiping area not only initiates high-frequency wiping in a key area but also ensures that rain on the windshield is removed in a timely manner, thus ensuring the driver's field of vision is clear and preventing safety accidents. By limiting the wiper's wiping area on the windshield, the wiper stroke is shortened during high-frequency wiping, reducing the risk of wiper damage. Illustration of the attached drawings Fig. 1 is a schematic block diagram of the structure of the wiper control system of the present invention; Fig. 2 is a flowchart of a wiper control method for a renewable energy vehicle according to the present invention; Fig. 3 is a schematic diagram of the hardware structure of the electronic device proposed by the present invention. Specific embodiments
[0017] For a better understanding of the objects, technical solutions, and advantages of the present invention, a further detailed description of the present invention follows in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention. Based on the embodiments in the present invention, all other embodiments that one of ordinary skill in the art can deduce without performing creative work are within the scope of the present invention. Embodiment 1:
[0018] Referring to Fig. 1, according to the present embodiment, a control method for windshield wipers on renewable energy vehicles is disclosed, which is applied to the wiper control system of the vehicle, the wiper control system comprising: wiper controller 101, rain sensor 102, wiper control terminal 103, windshield wiper 104, and central control display 105; wherein the wiper controller 101 is connected to each of the rain sensor 102, wiper control terminal 103, windshield wiper 104, and central control display 105; wherein the windshield wiper 104 is used to wipe the vehicle windshield. the method comprising: When the wiper controller 101 is in the first wiping state, the wiper controller 101 enters the rainstorm mode when the wiper controller 101 receives the high-speed gear signal sent from the wiper control terminal 103 or receives the rainstorm command sent from the central control display 105; the first wiping state is a working state in which the wiper controller 101 controls the wiper 104 to wipe a specific area of the windshield according to a maximum signal; the maximum signal is a frequency maximum value in a wiping frequency range; the wiping frequency range is a frequency range used by the rain sensor 102 to determine the wiping frequency of the wiper 104 according to the amount of precipitation in the environment where the vehicle is located. When the wiper controller 101 is in the second wiping state, the wiper controller 101 enters the rainstorm mode when the wiper controller 101 receives the rainstorm command sent from the central control display 105; wherein the rainstorm mode is used to instruct the wiper controller 101 to control the wiper 104 to wipe a special area of the windshield; wherein the high-speed gear signal is command information sent from the wiper control terminal 103 to instruct the wiper 104 to wipe the windshield at a high-speed frequency; wherein the rainstorm mode is used to instruct the wiper controller 101 to control the wiper 104 to wipe the key area of the vehicle windshield at a safety frequency, wherein the value of the safety frequency is greater than or equal to the high-speed frequency and the scope of the key area is smaller than that of the special area.
[0019] In this example, by setting a rainstorm mode, the wiper controller 101 can control the windshield wiper 104 to wipe the windshield in a key area at a safety frequency. That is, high-frequency wiping in a small wiping area not only initiates high-frequency wiping for a key area but also ensures that the rain on the windshield is removed in a timely manner, thereby ensuring a clear driver's field of vision and preventing safety accidents. By limiting the wiping area of a windshield wiper 104 on the windshield, the stroke of the windshield wiper 104 is shortened under high-frequency wiping, thereby reducing the risk of damage to the windshield wiper 104.
[0020] When the wiper controller 101 is in the first wiping state, the wiper controller 101 enters the rainstorm mode when the wiper controller 101 receives the high-speed gear signal sent from the wiper control terminal 103 or receives the rainstorm command sent from the central control display 105; so the wiper controller 101 enters the rainstorm mode in an automatic wiping scenario (i.e., a scene in which the wiping frequency of the wiper 104 is determined based on the rainfall of the rain sensor 102). Once the maximum value of the wiping frequency range is reached, the driver only needs to operate the wiper control terminal 103 to generate the high-speed gear signal or generate the rainstorm command via the central control display 105 for the wiper controller 101 to enter the rainstorm mode, making it easier for the driver to enter the rainstorm mode.
[0021] When the wiper controller 101 is in the second wiping state, the wiper controller 101 enters the rainstorm mode when the wiper controller 101 receives the rainstorm command sent from the central control display 105, so that the wiper controller 101 is in the manual wiping scenario (ie, the scene where the wiper 104 is controlled according to the high-speed gear signal sent from the wiper control terminal 103). Then, the driver only needs to operate the central control display 105 to generate the rainstorm command for the wiper controller 101 to enter the rainstorm mode, which makes it easier for the driver.
[0022] At the same time, the central control display 105 has the highest priority, so that the rainstorm command generated by the central control display 105 can cause the wiper controller 101 to enter the rainstorm mode in both automatic and manual wiping scenarios, thereby ensuring the reliability of entering the rainstorm mode.
[0023] In the automatic wiping scenario, the driver can enter the rainstorm mode when the driver selects the wiper control terminal 103 (ie, setting the wiper control terminal 103 to the high-speed gear so that the high-speed gear signal is generated), so that the driver does not need to operate the central control display 105, thereby further providing operation convenience to the driver and avoiding the driver distracting the driver's attention by finding and touching the rainstorm button used to generate the rainstorm command on the central control display 105, which leads to the occurrence of driving risks.
[0024] In the manual wiping scenario, the driver needs to trigger the rainstorm button of the central control display 105 to generate a rainstorm command so that the wiper controller 101 enters the rainstorm mode, so that the driver can enter the rainstorm mode only through the central control display 105, and the wiper controller 101 will not accidentally enter the rainstorm mode because the driver performs other operations (for example, frequently operating the wiper control terminal 103), which ensures that the wiper controller 101 operates completely in accordance with the driver's intention in the manual wiping scenario and ensures reliability in the manual wiping scenario.
[0025] In this embodiment, the wiper controller 101 is a device for steering and controlling the windshield wiper 104, typically located on a steering wheel or dashboard next to the driver's seat of the vehicle. The primary function of the wiper controller 101 is to start, stop, and adjust the operation of the windshield wiper 104 to remove rain, snow, or other debris from the windshield, thereby ensuring the driver's visibility remains clear and improving driving safety.
[0026] In this embodiment, the wiper controller 101 has the following functions: Start and Stop: By turning or sliding a switch or button on the wiper controller 101, the driver can start the wiper 104 to work, removing raindrops or other debris from the windshield. Pressing the switch or button again stops the operation of the wiper 104. Speed Control: The wiper controller 101 generally allows the driver to adjust the speed of the wiper 104 to accommodate varying levels of precipitation. There are often multiple speed options, including fast, medium, and slow.Rain sensing function based on rain sensor 102: Some modern vehicles are equipped with rain-sensing windshield wiper systems 104 that automatically adjust the speed of the windshield wiper 104 based on the sensed rain intensity. This allows the windshield wiper 104 to operate automatically when needed, without requiring manual intervention by the driver. Cleaning function: The wiper controller 101 typically also includes a cleaning water spray function that allows the driver to spray cleaning fluid onto the windshield using the water spray to remove more stubborn dirt.The specific design and features of the wiper control 101 may vary depending on the vehicle manufacturer and model, but in general, they are critical vehicle safety devices that help keep the driver's view clear and reduce the risk of driving in rainy or inclement weather.
[0027] Using a wiper lever as the wiper control terminal 103, the wiper lever is a device for operating and controlling a vehicle's windshield wiper 104, typically located on a steering wheel or dashboard near the driver's seat. The control lever is typically a rod, and the driver can control the operation of the wiper 104 by turning, sliding, or pressing a switch or button thereon. These operations include starting, stopping, speed adjustment, and water spray cleaning functions.
[0028] In this embodiment, the wiper stalk functions include: Start and Stop: By turning or pressing a switch or button on the stalk, the driver can start the windshield wiper 104 to operate to remove raindrops or other debris from the windshield. Pressing the switch or button again stops the operation of the windshield wiper 104. Speed Control: The wiper stalk typically has multiple speed settings, allowing the driver to adjust the speed of the windshield wiper 104 to accommodate varying levels of precipitation. The speed settings typically include Fast, Medium, and Slow. Cleaning Function: There is also typically a button or switch on the control stalk to activate the water spray cleaning function of the windshield wiper 104.Pressing this button sprays cleaning fluid onto the windshield to remove stubborn dirt. The specific design and function of the wiper lever may vary depending on the vehicle manufacturer and model, but the above features are typically available to help the driver maintain clear visibility in rainy or inclement weather, thereby improving driving safety.
[0029] The rain sensor 102, referred to as the Rain Light Sensor (RLS), monitors the amount of rain on the windshield, monitors sunlight illumination, and provides control signals to the electrical system through circuit calculations.
[0030] The central control display 105 and the wiper control terminal 103 are connected to the body control module 106. The central control display 105 generates rainstorm commands through the body control module 106 according to the driver clicking the rainstorm button on the central control display 105. The wiper control terminal 103 generates automatic gear signals and gear signals through the body control module 106 according to the driver's automatic gear operation, high-speed gear signals, and non-high-speed gear signals in the wiper control terminal 103. The gear signals include high-speed gear signals and non-high-speed gear signals. The body control module 106 is a BCM, fully known as the Body Control Module (BCM), which is one of the key components in the vehicle's electronic control system.It is mainly responsible for controlling the electrical equipment of various body systems, such as lights, independent heaters, windshield wipers, car doors and windows, etc. It can also communicate with the CAN communication network and encode a range of code in the vehicle to complete various sensing and control functions.
[0031] The windshield wiper 104 is used to remove rain, snow, and other deposits from the windshield to provide the driver with a clear view and improve driving safety. The windshield wiper 104 typically consists of a rubber scraper or brush mounted on the windshield and moved by an electric motor or manual operation to wipe away rain or other deposits. In extreme weather conditions, the windshield wipers 104 are very important because they can help the driver maintain good visibility and reduce the risk of accidents. In addition to the front windshield wiper 104, some vehicles are equipped with a rear windshield wiper 104 to clean rain and dirt from the rear windshield. Embodiment 2:
[0032] This embodiment is a specific application scenario of the above embodiment 1. Through this embodiment, the method provided by the present invention can be described more clearly and specifically.
[0033] Hereinafter, the method provided by this embodiment will be specifically described by using a rainstorm mode for wiping the windows of a vehicle in a wiper control system, that uses a wiper control method on renewable energy vehicles is input as an example. It should be noted that the present embodiments are only exemplary and do not limit the scope of the embodiments of the present invention.
[0034] The application provides, with reference to Fig. 1 and Fig. 2 provides a control method for windshield wipers on renewable energy vehicles. By setting a rainstorm mode, the wiper controller can control the wiper to wipe the windshield in a key area at a safety frequency. That is, high-frequency wiping in a small wiping area not only initiates high-frequency wiping for a key area but also ensures that the rain on the windshield is removed in a timely manner, thereby ensuring the driver's field of vision is clear and preventing safety accidents. By limiting the wiping area of a windshield wiper on the windshield, the stroke of the wiper is shortened under high-frequency wiping, reducing the risk of wiper damage.
[0035] The present application provides a wiper control method on renewable energy vehicles that is applied to the wiper control system of the vehicle, the wiper control system comprising: wiper controller 101, rain sensor 102, wiper control terminal 103, windshield wiper 104, and central control display 105; wherein the wiper controller 101 is connected to each of the rain sensor 102, wiper control terminal 103, windshield wiper 104, and central control display 105; wherein the windshield wiper 104 is used to wipe the vehicle windshield. the method comprising: S201: If the wiper controller 101 is in the first wiping state, the wiper controller 101 enters the rainstorm mode when the wiper controller 101 receives the high-speed gear signal sent from the wiper control terminal 103 or receives the rainstorm command sent from the central control display 105. The first wiping state is a working state in which the wiper controller 101 controls the wiper 104 to wipe a specific area of the windshield according to a maximum signal; the maximum signal is a frequency maximum value in a wiping frequency range; the wiping frequency range is a frequency range used by the rain sensor 102 to determine the wiping frequency of the wiper 104 according to the amount of precipitation in the environment where the vehicle is located. S202: If the wiper controller 101 is in the second wiping state, the wiper controller 101 enters the rainstorm mode when the wiper controller 101 receives the rainstorm command sent from the central control display 105; the rainstorm mode is used to instruct the wiper controller 101 to control the wiper 104 to wipe a specific area of the windshield; the high-speed gear signal is command information sent from the wiper control terminal 103 to instruct the wiper 104 to wipe the windshield at a high-speed frequency.wherein the rainstorm mode is used to instruct the wiper controller 101 to control the wiper 104 to wipe the key area of the vehicle glass at a safety frequency, the value of the safety frequency being greater than or equal to the high-speed frequency and the circumference of the key area being smaller than that of the special area;
[0036] Optionally, when the wiper controller 101 is in the second wiping state, the wiper controller 101 receives the rainstorm command sent from the front camera. The wiper controller 101 enters the rainstorm mode. When the front camera detects that the light transmittance of the windshield of the renewable energy vehicle is less than the preset light transmittance threshold, a rainstorm signal is generated. The light transmittance is the intensity of the light entering the interior of the renewable energy vehicle through the windshield. In this embodiment, rain has a serious impact on the driver's visibility. Even though a wiper is installed on the windshield, the visible distance is greatly shortened and visibility is greatly reduced due to the reduced light transmittance caused by rain.It is very difficult to correctly observe and judge traffic and pedestrians and correctly select the driving route. Therefore, when the front camera detects that the windshield's transmittance has been reduced to the transmittance threshold, it sends a rainstorm command to the wiper controller 101, causing the wiper controller 101 to enter the rainstorm mode to ensure camera clarity and thereby protect the safety of pedestrians and vehicles. S203: When the wiper controller 101 determines that the current vehicle speed exceeds a preset vehicle speed threshold and / or that the precipitation around the vehicle is below a precipitation threshold, the wiper controller 101 stops the rainstorm mode; and / or. S204: If the wiper controller 101 determines that the current temperature does not exceed a temperature threshold, the wiper controller 101 stops the rainstorm mode. S205: If it is determined that the wiper controller 101 is in the first wiping state before entering the rainstorm mode, the wiper controller 101 returns to the first wiping state; if it is determined that the wiper controller 101 is in the second wiping state before entering the rainstorm mode, the wiper controller 101 returns to the second wiping state. S206: If the wiper controller 101 determines that it is in the first wiping state before entering the rainstorm mode, the first wiping frequency is obtained from the preset damping assembly, and the wiper controller 101 controls the wiper 104 to wipe the special area of the windshield according to the first wiping frequency. The first wiping frequency is lower than the high-speed frequency characterized by the high-speed gear signal. For example, the high-speed frequency is 60 cpm and the second wiping frequency is 40 cpm. Cpm is the abbreviation of count per minute. Hz refers to the count per second, so the conversion relationship is 1 cpm = (1 / 60) Hz or 1 Hz = 60 cpm. Frequency, the number of periodic changes performed per unit time, is the amount that describes the frequency of periodic movements.The commonly used symbol f or v is expressed as one second, and the symbol is s-1.
[0037] When it is determined that the windshield wiper 101 is in the second wiping state before entering the rainstorm mode, the second wiping frequency is obtained from the preset damper assembly, and the wiper controller 101 controls the windshield wiper 104 to wipe the special area of the windshield according to the second wiping frequency; where the second wiping frequency is lower than the high-speed frequency characterized by the high-speed gear signal; for example, the high-speed frequency is 70 cpm and the second wiping frequency is 45 cpm. S207: When the wiper controller 101 receives the conventional central control signal sent from the central control display 105, the wiper controller 101 stops the rainstorm mode and controls the wiper 104 to wipe the windshield according to the conventional central control frequency in the conventional central control signal; the conventional central control signal is used to instruct the wiper controller 101 to control the wiper 104 to wipe the special area at a frequency lower than the maximum frequency value; the conventional central control frequency is generated from the central control display 105 and is lower than the frequency value of the maximum frequency value;For example, the conventional central control signal is the electrical signal generated to control the windshield wiper, where the position of the control lever is controlled by the user through the operation on the wiper control side on the central control display to generate the conventional central control signal with different conventional central control frequencies (high wiping frequency, medium wiping frequency, low wiping frequency) by switching the control lever and clicking on the high-quality wiping speed, the medium wiping speed, the low wiping speed, etc. on the central control display by the user. S208: When the wiper controller 101 receives the end stop signal sent from the central control display 105, the wiper controller 101 controls the wiper 104 to rotate to an initial position and stops the wiper 104 from wiping, where the initial position is the position of the wiper at the time of starting and is generally a position where the wiper blade of the wiper is parallel to the lower edge of the glass. S209: When the wiper controller 101 receives the conventional terminal signal transmitted from the wiper control terminal 103, the wiper controller 101 stops the rainstorm mode and controls the wiper 104 to wipe the windshield according to the conventional terminal frequency in the conventional terminal signal; wherein the conventional terminal signal is used to instruct the wiper controller 101 to control the wiper 104 to wipe the special area at a frequency lower than the frequency maximum value; wherein the conventional terminal frequency is generated from the wiper control terminal 103 and the value is lower than the frequency value of the frequency maximum value.For example, the conventional central control signal is the electrical signal generated for controlling the windshield wiper, wherein the position of the control lever of the wiper control terminal is controlled by the user through the operation to generate the conventional terminal signal with different conventional terminal frequencies (high wiping frequency, medium wiping frequency, low wiping frequency) by switching the control lever and clicking the high wiping speed, the medium wiping speed, the low wiping speed, etc. on the terminal display by the user. S210: When the wiper controller 101 receives the end stop signal sent from the terminal display 105, the wiper controller 101 controls the wiper 104 to rotate to a home position and stops the wiper 104 from wiping. The home position is the position of the wiper at the time of start-up and is generally a position where the wiper blade is parallel to the lower edge of the windshield. In this example, by setting a rainstorm mode, the wiper controller 101 can control the wiper 104 to wipe the windshield in a key area at a safety frequency.That is, high-frequency wiping in a small wiping area not only initiates high-frequency wiping for a key area but also ensures that rain on the windshield is removed in a timely manner, thereby ensuring the driver's field of vision is clear and preventing safety accidents. By limiting the wiping area of a windshield wiper 104 on the windshield, the stroke of the windshield wiper 104 is shortened under high-frequency wiping, thereby reducing the risk of damage to the windshield wiper 104.
[0038] When the wiper controller 101 is in the first wiping state, the wiper controller 101 enters the rainstorm mode when the wiper controller 101 receives the high-speed gear signal sent from the wiper control terminal 103 or receives the rainstorm command sent from the central control display 105; so the wiper controller 101 enters the rainstorm mode in an automatic wiping scenario (i.e., a scene in which the wiping frequency of the wiper 104 is determined based on the rainfall of the rain sensor 102). Once the maximum value of the wiping frequency range is reached, the driver only needs to operate the wiper control terminal 103 to generate the high-speed gear signal or generate the rainstorm command via the central control display 105 for the wiper controller 101 to enter the rainstorm mode, making it easier for the driver to enter the rainstorm mode.
[0039] When the wiper controller 101 is in the second wiping state, the wiper controller 101 enters the rainstorm mode when the wiper controller 101 receives the rainstorm command sent from the central control display 105, so that the wiper controller 101 is in the manual wiping scenario (ie, the scene where the wiper 104 is controlled according to the high-speed gear signal sent from the wiper control terminal 103). Then, the driver only needs to operate the central control display 105 to generate the rainstorm command for the wiper controller 101 to enter the rainstorm mode, which makes it easier for the driver.
[0040] At the same time, the central control display 105 has the highest priority, so that the rainstorm command generated by the central control display 105 can cause the wiper controller 101 to enter the rainstorm mode in both automatic and manual wiping scenarios, thereby ensuring the reliability of entering the rainstorm mode.
[0041] In this embodiment, the wiper controller 101 controls the speed of the wiper motor by adjusting the duty cycle of the pulse current output from the power supply to the motor in the wiper according to the maximum frequency, the high-speed frequency, the conventional central control frequency, the conventional terminal frequency, the first wiping frequency, or the second wiping frequency, to control the wiping frequency so that the wiping frequency corresponds to the maximum frequency, the high-speed frequency, the conventional central control frequency, the conventional terminal frequency, the first wiping frequency, or the second wiping frequency. Among them, pulse width modulation (PWM) technology is used to adjust the duty cycle of the pulse current, and pulse width modulation is a method for digitally encoding the analog signal level.By using a high-resolution counter, the duty cycle of the square wave is modulated to encode the level of a specific analog signal, and then the duty cycle of the current output from the power supply to the motor is adjusted. In the automatic wiping scenario, when the driver selects the wiper control terminal 103 (that is, setting the wiper control terminal 103 to the high-speed gear so that the high-speed gear signal is generated), the driver can enter the rainstorm mode, so that the driver does not need to operate the central control display 105, thereby further providing the driver with operating convenience and avoiding the driver's attention being distracted by finding and touching the rainstorm button used to generate the rainstorm command on the central control display 105, which leads to driving risks.
[0042] In the manual scraping scenario, the driver needs to trigger the rainstorm button of the central control display 105 to generate a rainstorm command so that the wiper controller 101 enters the rainstorm mode, so that the driver can enter the rainstorm mode only through the central control display 105, and the wiper controller 101 will not accidentally enter the rainstorm mode because the driver performs other operations (for example, frequently operating the wiper control terminal 103), which ensures that the wiper controller 101 operates completely in accordance with the driver's intention in the manual wiping scenario and ensures reliability in the manual wiping scenario.
[0043] In this embodiment, the wiper controller 101 is a device for steering and controlling the windshield wiper 104, typically located on a steering wheel or dashboard next to the driver's seat of the vehicle. The primary function of the wiper controller 101 is to start, stop, and adjust the operation of the windshield wiper 104 to remove rain, snow, or other debris from the windshield, thereby ensuring the driver's visibility remains clear and improving driving safety.
[0044] In this embodiment, the wiper controller 101 has the following functions: Start and Stop: By turning or sliding a switch or button on the wiper controller 101, the driver can start the wiper 104 to work, removing raindrops or other debris from the windshield. Pressing the switch or button again stops the operation of the wiper 104. Speed Control: The wiper controller 101 generally allows the driver to adjust the speed of the wiper 104 to accommodate varying levels of precipitation. There are often multiple speed options, including fast, medium, and slow.Rain sensing function based on rain sensor 102: Some modern vehicles are equipped with rain-sensing windshield wiper systems 104 that automatically adjust the speed of the windshield wiper 104 based on the sensed rain intensity. This allows the windshield wiper 104 to operate automatically when needed, without requiring manual intervention by the driver. Cleaning function: The wiper controller 101 typically also includes a cleaning water spray function that allows the driver to spray cleaning fluid onto the windshield using the water spray to remove more stubborn dirt.The specific design and features of the wiper control 101 may vary depending on the vehicle manufacturer and model, but in general, they are critical vehicle safety devices that help keep the driver's view clear and reduce the risk of driving in rainy or inclement weather.
[0045] Using a wiper lever as the wiper control terminal 103, the wiper lever is a device for operating and controlling the windshield wiper 104 of a vehicle, typically located on a steering wheel or dashboard near the driver's seat of the vehicle. The control lever is typically a rod, and the driver can control the operation of the windshield wiper 104 by turning, sliding, or pressing a switch or button thereon.
[0046] These operations include starting, stopping, speed adjustment and water spray cleaning functions.
[0047] In this embodiment, the wiper stalk functions include: Start and Stop: By turning or pressing a switch or button on the stalk, the driver can start the windshield wiper 104 to operate to remove raindrops or other debris from the windshield. Pressing the switch or button again stops the operation of the wiper 104. Speed Control: The wiper stalk typically has multiple speed settings, allowing the driver to adjust the speed of the wiper 104 to accommodate varying levels of precipitation. The speed settings typically include Fast, Medium, and Slow. Cleaning Function: There is also typically a button or switch on the control stalk to activate the water spray cleaning function of the wiper 104.Pressing this button sprays cleaning fluid onto the windshield to remove stubborn dirt. The specific design and function of the wiper lever may vary depending on the vehicle manufacturer and model, but the above features are typically available to help the driver maintain clear visibility in rainy or inclement weather, thereby improving driving safety.
[0048] The rain sensor 102, referred to as the Rain Light Sensor (RLS), monitors the amount of rain on the windshield, monitors sunlight illumination, and provides control signals to the electrical system through circuit calculations.
[0049] The central control display screen 105 and the wiper control terminal 103 are connected to the body control module 106. The central control display screen 105 generates rainstorm commands through the body control module 106 according to the driver clicking the rainstorm button on the central control display screen 105. The wiper control terminal 103 generates automatic gear signals and gear signals through the body control module 106 according to the driver's automatic gear operation, high-speed gear signals, and non-high-speed gear signals in the wiper control terminal 103, wherein the gear signals include high-speed gear signals and non-high-speed gear signals. The body control module 106 is a BCM, fully known as the Body Control Module (BCM), which is one of the key components in the vehicle's electronic control system.It is mainly responsible for controlling the electrical equipment of various systems of the body, such as lights, independent heaters, windshield wipers, car doors and windows, etc. It can also communicate with the CAN communication network and encode a range of code in the vehicle to complete various sensing and control functions.
[0050] The windshield wiper 104 is used to remove rain, snow, and other deposits from the windshield to provide the driver with a clear view and improve driving safety. The windshield wiper 104 typically consists of a rubber scraper or brush mounted on the windshield and moved by an electric motor or manual operation to wipe away rain or other deposits. In extreme weather conditions, the windshield wipers 104 are very important because they can help the driver maintain good visibility and reduce the risk of accidents. In addition to the front windshield wiper 104, some vehicles are equipped with a rear windshield wiper 104 to clean rain and dirt from the rear windshield.
[0051] If the speed sensor detects that the vehicle's current speed exceeds the speed threshold and / or if it detects that the precipitation in the vehicle's surroundings is lower than the preset precipitation threshold, this indicates that the vehicle is capable of washing away the rainwater on the windshield at the current speed. If it returns to Rainstorm Mode at this time, the driver will be disturbed, causing Rainstorm Mode to stop.
[0052] When the temperature sensor detects that the current temperature of the wiper 104 exceeds the temperature threshold, it means that the current temperature of the wiper 104 is relatively high, and in order to avoid damage to the wiper 104, the rainstorm mode is stopped to ensure the safety of the wiper 104.
[0053] When the wiper controller 101 receives the conventional central control signal sent from the central control display 105, the driver wants to exit the rainstorm mode through the central control display 105, therefore, the wiper controller 101 stops the rainstorm mode to ensure the reliability of exiting the rainstorm mode.
[0054] After exiting the rainstorm mode, the vehicle likely needs to continue wiping. To ensure that the driver's view is not obstructed after exiting the rainstorm mode, this embodiment instructs the wiper controller 101 to control the windshield wiper 104 via the conventional central control signal to wipe the windshield at a frequency lower than the maximum frequency value.
[0055] Sometimes, when the driver is driving at high speed, it is inconvenient to operate the central control display 105. The driver can generate a conventional terminal signal by operating the wiper control terminal 103 to instruct the wiper controller 101 to exit the rainstorm mode. To ensure that the driver's visibility is not obstructed after exiting the rainstorm mode, this embodiment instructs the wiper controller 101 to control the windshield wiper 104 via the conventional terminal signal to wipe the windshield at a frequency lower than the maximum frequency.
[0056] In a preferred embodiment, the wiper control 101 is in a first wiping state, comprising: If the wiper controller 101 detects that the rain sensor 102 is switched on, the wiper controller 101 sends an automatic gear command to the rain sensor 102; wherein the rain sensor 102 detects precipitation in the environment in which the vehicle is located according to the automatic gear command and generates a frequency command according to the precipitation, wherein the rain sensor 102 transmits the frequency command to the wiper controller 101; wherein the wiper controller 101 controls a windshield wiper 104 to wipe a glass of a vehicle window according to the frequency command, and determines that the wiper controller 101 is in the first wiping state.
[0057] In this example, the driver operates the wiper control terminal 103 to the automatic gear to turn on the rain sensor 102. When the wiper controller 101 detects that the rain sensor 102 is turned on, the wiper controller 101 enters the automatic wiping scenario. At this time, the wiper sensor detects the precipitation in the environment where the vehicle is located and generates a wiping frequency at which the wiper 104 should wipe the special area according to the precipitation. It sends the frequency command recording the wiping frequency to the wiper controller 101. The wiper controller 101 controls the wiper 104 to wipe the windshield according to the wiping frequency. At this time, the wiper controller 101 enters the first wiping state, which is the wiper mode under the automatic wiping scenario.
[0058] If the speed sensor detects that the vehicle's current speed exceeds the speed threshold and / or if it detects that the precipitation in the vehicle's surroundings is lower than the preset precipitation threshold, this means that the vehicle is able to wash away the rainwater on the windshield at the current speed. If it returns to rainstorm mode at this time, it will alert the driver and stop rainstorm mode. At the same time, by setting the precipitation threshold, this means that the vehicle does not need to remain in rainstorm mode if the precipitation in the vehicle's surroundings is lower than the precipitation threshold.
[0059] When the temperature sensor detects that the current temperature of the wiper 104 exceeds the temperature threshold, it means that the current temperature of the wiper 104 is relatively high, and in order to avoid damage to the wiper 104, the rainstorm mode is stopped to ensure the safety of the wiper 104.
[0060] When the wiper controller 101 receives the conventional central control signal sent from the central control display 105, the driver wants to exit the rainstorm mode through the central control display 105, therefore, the wiper controller 101 stops the rainstorm mode to ensure the reliability of exiting the rainstorm mode.
[0061] After exiting the rainstorm mode, the vehicle likely needs to continue wiping. To ensure that the driver's view is not obstructed after exiting the rainstorm mode, this embodiment instructs the wiper controller 101 to control the windshield wiper 104 via the conventional central control signal to wipe the windshield at a frequency lower than the maximum frequency value.
[0062] Sometimes, when the driver is driving at high speed, it is not convenient to operate the central control display 105. The driver can generate a conventional terminal signal by operating the wiper control terminal 103 to instruct the wiper controller 101 to exit the rainstorm mode. To ensure that the driver's visibility is not obstructed after exiting the rainstorm mode, this embodiment instructs the wiper controller 101 to control the wiper 104 via the conventional terminal signal to wipe the windshield at a frequency lower than the maximum frequency.
[0063] If the wiper controller 101 is in the first wiping state before entering the rain, the wiper controller 101 re-enters the first wiping state after exiting the rainstorm mode, so that after entering the rainstorm mode from the automatic wiping scene, when exiting the rainstorm mode again, the wiper controller 101 re-enters the automatic wiping scene to ensure the consistency of the wiping scenes.
[0064] If the wiper controller 101 is in the first wiping state before entering the rain, the wiper controller 101 re-enters the first wiping state after exiting the rainstorm mode, so that after entering the rainstorm mode from the manual wiping scene, the wiper controller 101 re-enters the manual wiping scene when exiting the rainstorm mode again in order to ensure the consistency of the wiping scenes.
[0065] In a preferred embodiment, the wiper control 101 is in a second wiping state, comprising: If the wiper controller 101 does not detect that the rain sensor 102 is turned on and detects a gear signal sent from the wiper control terminal 103, the wiper controller 101 controls the windshield wiper 104 to wipe the windshield according to a frequency in the gear signal; wherein the gear signal is one of the high-speed gear signal and at least one non-high-speed gear signal; wherein the non-high-speed gear signal is sent from the wiper control terminal 103 for command information instructing the windshield wiper 104 to wipe the windshield at a non-high-speed frequency; wherein the non-high-speed frequency is lower than the high-speed frequency.
[0066] In this example, the driver operates the wiper control terminal 103 to a high-speed or non-high-speed gear with the rain sensor 102 off. If the wiper controller 101 does not detect that the rain sensor 102 is off, the wiper controller 101 enters a manual wiping scenario, and the wiper controller 101 controls the windshield wiper 104 to wipe according to the gear signal sent from the wiper control terminal 103.
[0067] For example, the high-speed frequency is 60 cpm, and the non-high-speed frequency includes: 50 cpm, 40 cpm, 30 cpm, and 20 cpm. If the frequency of the received gear signal is 60 cpm, it is determined that the received gear signal is a high-speed gear signal; if the frequency of the received gear signal is one of 50 cpm, 40 cpm, 30 cpm, and 20 cpm, it is determined that the received gear signal is a non-high-speed gear signal.
[0068] In a preferred embodiment, the wiper control system further comprises: a vehicle speed sensor and a temperature sensor; wherein the vehicle speed sensor is connected to the wiper controller 101, the vehicle speed sensor being used to detect the vehicle speed; wherein the temperature sensor is connected to the wiper controller 101, the temperature sensor being used to detect the temperature of the windshield wiper 104; Before the wiper controller 101 enters the rainstorm mode, the method further comprises: wherein the wiper controller 101 triggers the vehicle speed sensor to feed back the current vehicle speed of the vehicle; If the wiper controller 101 determines that the current vehicle speed does not exceed a preset vehicle speed threshold, the wiper controller 101 triggers the temperature sensor to feed back the current temperature of the windshield wiper 104; If the wiper controller 101 determines that the current temperature does not exceed a preset temperature threshold, the wiper controller 101 enters a rainstorm mode.
[0069] In this example, in a rainstorm environment, the rainwater on the windshield is washed away due to the high speed of the vehicle when the vehicle is traveling at high speed. At this time, when the vehicle enters the rainstorm mode, the wiper 104 obstructs the driver's field of vision by wiping the key area. Therefore, if the current speed does not exceed the speed threshold, this means that the vehicle cannot wash away the rainwater on the windshield at the current speed, and the wiper controller 101 can enter the rainstorm mode; and if the current speed exceeds the speed threshold, this means that the vehicle can wash away the rainwater on the windshield at the current speed, and the wiper controller 101 does not need to enter the rainstorm mode.
[0070] Since the windshield wiper 104 wipes the windshield at a high frequency in the key area in rainstorm mode, the windshield wiper 104 experiences a heavy operating load in rainstorm mode. To prevent the temperature of the windshield wiper 104 from burning out, the current temperature of the windshield wiper 104 is detected via the temperature sensor. If the current temperature does not exceed the temperature threshold, the wiper controller 101 can directly enter rainstorm mode. If the current temperature exceeds the temperature threshold, the wiper controller 101 is prevented from entering rainstorm mode to protect the windshield wiper 104.
[0071] For example, assuming the temperature threshold is 80 °C, then it will enter rainstorm mode if the current temperature is not greater than 80 °C, and will not enter rainstorm mode if the current temperature is greater than 80 °C.
[0072] In a preferred embodiment, the wiper control system further comprises a configuration module 107, wherein the configuration module 107 is connected to the wiper control 101; wherein the wiper controller 101 then switches to the rainstorm mode, comprising: Setting the rain frequency to the safety frequency when the wiper controller 101 extracts a rain frequency parameter from the configuration module 107; wherein the rain frequency parameter is greater than or equal to the maximum value of the frequency; Setting the maximum value of the frequency to the safety frequency if the wiper controller 101 does not extract the rain frequency parameter from the configuration module 107; The wiper controller 101 extracts the upper angle parameter (URP-A) and the lower angle parameter (LRP+A) from the configuration module 107 and controls the wiper 104 to take the lower angle parameter as the lower end point and the upper angle parameter as the upper end point, respectively, to wipe the windshield at a safety frequency; wherein the upper end point and the lower end point are located in a key area on the windshield.
[0073] In this example, the rain frequency parameter can be set in configuration module 107. When wiper controller 101 enters rainstorm mode, the rain frequency parameter is extracted from configuration module 107 and set to a safety frequency, wiping the windshield at a safety frequency. At the same time, the rain frequency parameter can also be left unset in configuration module 107. Then, the maximum frequency value in configuration module 107 is taken as a safety frequency, and the windshield is wiped at this safety frequency to ensure that windshield wiper 104 wipes the windshield at a high frequency.
[0074] At the same time, the key range is determined by setting the upper angle parameters and the lower angle parameters to achieve customized management of the key range.
[0075] For example, if only the sweep frequency interval [20 cpm, 60 cpm] is recorded in configuration module 107, then 60 cpm is taken as the safety frequency. If not only the sweep frequency interval [20 cpm, 60 cpm] is recorded in configuration module 107, but also the storm frequency parameter: 70 cpm, then 70 cpm is taken as the safety frequency.
[0076] In the configuration module 107, an angular range of a special range is defined, for example: [LRP: 0°, URP: 90°], where LRP is the lower end point of the special range and URP is the upper end point of the special range. Thus, the wiper controller 101 controls the windshield wiper 104 to wipe the windshield within an angular range of 0°-90°, which is considered a special range.
[0077] In the configuration module 107, the upper angle parameter is 20° and the lower angle parameter is 70°. Then, the wiper controller 101 controls the windshield wiper 104 to wipe the windshield within the angular range of 20°–70°, which is considered the key range.
[0078] In a preferred embodiment, the wiper control system further comprises a fault detection module 108, wherein the fault detection module 108 is connected to the wiper controller 101, wherein the fault detection module 108 is used to detect whether the vehicle and the windshield wiper 104 have faults;
[0079] After the wiper controller 101 has entered the rainstorm mode, the method further includes: When the wiper controller 101 receives a fault signal sent from the fault detection module 108, the wiper controller 101 stops the rainstorm mode; the fault signal characterizes that the vehicle and / or the windshield wiper 104 are experiencing faults.
[0080] In this example, if the fault detection module 108 detects a fault in the vehicle and / or the windshield wiper 104, if the wiper controller 101 remains in rainstorm mode, the vehicle and / or the windshield wiper 104 will continue to be damaged, causing the fault to the vehicle and / or the windshield wiper 104 to expand.
[0081] Accordingly, the fault detection module 108 exits the rainstorm mode when a fault is detected in the vehicle and / or the windshield wiper 104 to avoid increasing the magnitude of the fault or deepening the fault.
[0082] The fault detection module 108 (commonly referred to as a vehicle diagnostic module) is an electronic device or software tool for monitoring and detecting vehicle systems, engines, and other critical components. These modules are an important component of today's vehicles and are designed to identify and document vehicle performance problems, faults, and error codes.
[0083] The main functions of the fault detection module 108 include: Diagnostics: Monitoring various vehicle systems, such as engines, transmissions, braking systems, emissions systems, etc., to detect any anomalies or malfunctions. Recording of trouble codes: When the module detects a problem, it generates an error code, called a DTC, to indicate the type and location of the problem. These DTCs can be used by technicians or vehicle owners for diagnosis and repair. Real-time data monitoring: Modules can often monitor and record real-time vehicle data, such as vehicle speed, engine temperature, oil pressure, air-fuel ratio, etc., to diagnose problems and optimize performance.Driver Warning: Some fault detection modules 108 can send a warning signal to the driver, such as a check engine light or other warning light, indicating that a problem exists that needs to be addressed. Repair Instructions: Some advanced vehicle diagnostic modules can also provide repair instructions, including instructions for the owner or technician on how to correct a specific problem. These modules typically communicate with the vehicle's electronic system through the vehicle's diagnostic interface, such as the OBD-II (On-Board Diagnostics II) interface. Vehicle manufacturers use different standards and protocols to implement these functions, so different makes and models of vehicles may use different fault detection modules 108.These modules are important for quickly and accurately locating and resolving vehicle problems and help improve driving safety and vehicle performance.
