Technical Field
[0001] This invention relates to the field of new energy vehicle technology, and in particular to a windshield wiper control method, electronic device and storage medium for new energy vehicles. Background Technology
[0002] When a car is driven in heavy rain, the windows may become covered with too much water, obstructing the driver's view and threatening driving safety.
[0003] Currently, windshield wipers are typically controlled by a wiper controller to wipe the windows at high frequency. However, the inventors discovered that when a car is driving in heavy rain, the high-frequency wiping of the windows cannot remove the rainwater covering the windows in time. If the wiping frequency of the wipers is further increased, it can easily damage the wipers. Summary of the Invention
[0004] The purpose of this invention is to provide a windshield wiper control method, electronic device, and storage medium for new energy vehicles, in order to solve the problem that in the prior art, when a car is driven in heavy rain, the high-frequency wipers cannot remove the rainwater covering the windshield in time, and if the wiping frequency of the wipers is further increased, it is easy to damage the wipers.
[0005] To achieve the above objectives, the present invention provides a windshield wiper control method for a new energy vehicle, which is applied in the windshield wiper control system of the vehicle. The windshield wiper control system includes: a wiper controller, a rain sensor, a wiper control terminal, a wiper blade, and a central control display screen; the wiper controller is connected to the rain sensor, the wiper control terminal, the wiper blade, and the central control display screen respectively; the wiper blade is used to wipe the windshield of the vehicle.
[0006] The method includes:
[0007] When the wiper controller is in the first wiping state, if the wiper controller receives a high-speed signal from the wiper control terminal or a rainstorm command from the central control display screen, the wiper controller will enter the rainstorm mode.
[0008] When the wiper controller is in the second wiper state, if the wiper controller receives a rainstorm command sent by the central control display screen, the wiper controller will enter the rainstorm mode.
[0009] The first wiping state is the working state in which the wiper controller controls the wipers to wipe a designated area of the windshield based on a maximum value signal; the maximum value signal is the maximum value of a frequency in the wiping frequency range; the wiping frequency range is the frequency range used by the rain sensor to determine the wiping frequency of the wipers based on the rainfall in the environment where the car is located.
[0010] The second wiping state is the working state in which the wiper controller controls the wipers to wipe a designated area of the windshield according to the high-speed signal; the high-speed signal is sent by the wiper control terminal and is a command message used to instruct the wipers to wipe the windshield at a high-speed frequency.
[0011] The heavy rain mode is used to instruct the wiper controller to control the wipers to wipe the critical areas of the windshield at a safe frequency. The value of the safe frequency is greater than or equal to the high-speed frequency, and the range of the critical area is smaller than the specified area.
[0012] In the above scheme, the wiper controller is in the first wiping state, including:
[0013] If the wiper controller detects that the rain sensor is turned on, the wiper controller sends an automatic mode command to the rain sensor.
[0014] The rain sensor detects the amount of rainfall in the environment where the car is located according to the automatic transmission command, and generates a frequency command based on the amount of rainfall. The rain sensor then sends the frequency command to the wiper controller.
[0015] The wiper controller controls the wipers to wipe the car windows according to the frequency command, and determines that the wiper controller is in the first wiping state.
[0016] In the above scheme, the wiper controller is in the second wiping state, including:
[0017] If the wiper controller does not detect that the rain sensor is turned on, but detects the gear signal sent by the wiper control terminal, the wiper controller controls the wipers to wipe the windshield according to the frequency in the gear signal.
[0018] The gear signal is one of the high-speed gear signal and at least one non-high-speed gear signal; the non-high-speed gear signal is a command sent by the wiper control terminal to instruct the wipers to wipe the windshield at a non-high-speed frequency; the non-high-speed frequency is less than the high-speed frequency.
[0019] In the above solution, the wiper control system further includes: a vehicle speed sensor and a temperature sensor; the vehicle speed sensor is connected to the wiper controller and is used to detect the vehicle speed; the temperature sensor is connected to the wiper controller and is used to detect the temperature of the wiper blade.
[0020] Before the wiper controller enters the heavy rain mode, the method further includes:
[0021] The wiper controller triggers the vehicle speed sensor to provide feedback on the vehicle's current speed;
[0022] If the wiper controller determines that the current vehicle speed does not exceed a preset vehicle speed threshold, the wiper controller will trigger the temperature sensor to provide feedback on the current temperature of the wipers.
[0023] If the wiper controller determines that the current temperature does not exceed a preset temperature threshold, the wiper controller will enter the rainstorm mode.
[0024] In the above solution, the wiper control system further includes: a configuration module, which is connected to the wiper controller;
[0025] The wiper controller then enters heavy rain mode, including:
[0026] If the wiper controller extracts the rainstorm frequency parameter from the configuration module, it sets the rainstorm frequency as the safe frequency; wherein the rainstorm frequency parameter is greater than or equal to the maximum frequency value;
[0027] If the wiper controller does not extract the rainstorm frequency parameter from the configuration module, it sets the maximum frequency value as the safe frequency.
[0028] The wiper controller extracts the upper angle parameter and the lower angle parameter from the configuration module, and controls the wiper to wipe the windshield at the safe frequency with the lower angle parameter as the lower stop point and the upper angle parameter as the upper stop point; wherein the upper stop point and the lower stop point are located in the critical area on the windshield.
[0029] In the above solution, after the wiper controller enters the heavy rain mode, the method further includes:
[0030] If the wiper controller determines that the current vehicle speed exceeds a preset vehicle speed threshold and / or determines that the rainfall in the vehicle's surrounding environment is below a preset rainfall threshold, the wiper controller will stop the heavy rain mode; and / or
[0031] If the wiper controller determines that the current temperature exceeds a preset temperature threshold, the wiper controller will stop the rainstorm mode; and / or
[0032] The wiper control system further includes a fault detection module; the fault detection module is connected to the wiper controller, and the fault detection module is used to detect whether the vehicle and the wipers are malfunctioning; after the wiper controller enters the rainstorm mode, the method further includes: if the wiper controller receives a fault signal sent by the fault detection module, the wiper controller stops the rainstorm mode; wherein, the fault signal indicates that the vehicle and / or the wipers are malfunctioning.
[0033] In the above solution, after the wiper controller stops the heavy rain mode, the method further includes:
[0034] If it is determined that the wiper controller was in the first wiping state before entering the rainstorm mode, the wiper controller will re-enter the first wiping state.
[0035] If it is determined that the wiper controller was in the second wiping state before entering the rainstorm mode, the wiper controller will then re-enter the second wiping state.
[0036] In the above solution, after the wiper controller enters the heavy rain mode, the method further includes:
[0037] If the wiper controller receives a central control normal signal sent by the central control display, the wiper controller stops the rainstorm mode and controls the wipers to wipe the windshield according to the central control normal frequency in the central control normal signal; wherein, the central control normal signal is used to instruct the wiper controller to control the wipers to wipe the designated area at a frequency lower than the maximum frequency value; the central control normal frequency is generated by the central control display and is a frequency value lower than the maximum frequency value;
[0038] If the wiper controller receives a terminal normal signal sent by the wiper control terminal, the wiper controller stops the heavy rain mode and controls the wipers to wipe the windshield according to the terminal normal frequency in the terminal normal signal; wherein, the terminal normal signal is used to instruct the wiper controller to control the wipers to wipe the designated area at a frequency lower than the maximum frequency value; the terminal normal frequency is generated by the wiper control terminal and is a frequency value lower than the maximum frequency value.
[0039] To achieve the above objectives, the present invention also provides an electronic device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor of the electronic device executes the computer program, it implements the steps of the above-described windshield wiper control method for a new energy vehicle.
[0040] To achieve the above objectives, the present invention also provides a computer-readable storage medium storing a computer program, wherein the computer program stored in the storage medium, when executed by a processor, implements the steps of the above-described windshield wiper control method for a new energy vehicle.
[0041] This invention provides a windshield wiper control method, electronic device, and storage medium for new energy vehicles. By setting a heavy rain mode, the wiper controller can control the wipers to wipe the windshield at a safe frequency in key areas. That is, high-frequency wiping within a small wiping area not only ensures timely wiping of rainwater on the windshield by targeting key areas, thus ensuring clear visibility for the driver and preventing accidents, but also shortens the wiper's travel distance under high-frequency wiping by limiting the wiping range on the windshield, thereby reducing the risk of wiper damage.

[0044] Figure 3 This is a schematic diagram of the hardware structure of the electronic device proposed in this invention. Detailed Implementation
[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.
[0046] Example 1:
[0047] Please see Figure 1 This embodiment discloses a windshield wiper control method for a new energy vehicle, applied in the vehicle's windshield wiper control system. The windshield wiper control system includes: a wiper controller 101, a rain sensor 102, a wiper control terminal 103, a wiper blade 104, and a central control display screen 105. The wiper controller 101 is connected to the rain sensor 102, the wiper control terminal 103, the wiper blade 104, and the central control display screen 105, respectively. The wiper blade 104 is used to wipe the vehicle's windows.
[0048] The methods include:
[0049] When the wiper controller 101 is in the first wiping state, if the wiper controller 101 receives a high-speed signal from the wiper control terminal 103 or a rainstorm command from the central control display screen 105, the wiper controller 101 will enter the rainstorm mode. The first wiping state is the working state in which the wiper controller 101 controls the wiper 104 to wipe a designated area of the windshield according to the maximum value signal. The maximum value signal is the maximum value of the frequency in the wiping frequency range. The wiping frequency range is the frequency range used by the rain sensor 102 to determine the wiping frequency of the wiper 104 based on the rainfall in the environment where the car is located.
[0050] When the wiper controller 101 is in the second wiping state, if it receives a rainstorm command from the central control display screen 105, the wiper controller 101 will enter the rainstorm mode. The second wiping state is the working state in which the wiper controller 101 controls the wiper 104 to wipe a designated area of the window according to the high-speed signal. The high-speed signal is sent by the wiper control terminal 103 and is a command message to instruct the wiper 104 to wipe the window at a high-speed frequency. The rainstorm mode is used to instruct the wiper controller 101 to control the wiper 104 to wipe the key area of the window at a safe frequency. The value of the safe frequency is greater than or equal to the high-speed frequency, and the range of the key area is smaller than the designated area.
[0051] In this example, by setting the rainstorm mode, the wiper controller 101 can control the wiper 104 to wipe the windshield at a safe frequency in key areas. That is, high-frequency wiping is performed in a smaller wiping area. This not only ensures that the rainwater on the windshield is wiped away in time, thus ensuring clear visibility for the driver and preventing accidents, but also reduces the wiping range of the wiper 104 on the windshield by limiting the stroke of the wiper 104 under high-frequency wiping, thereby reducing the risk of damage to the wiper 104.
[0052] When the wiper controller 101 is in the first wiping state, if it receives a high-speed signal from the wiper control terminal 103 or a rainstorm command from the central control display 105, the wiper controller 101 will enter the rainstorm mode. This allows the wiper controller 101 to enter the rainstorm mode in automatic wiping scenarios (i.e., scenarios where the wiper frequency of the wiper 104 is determined by the rain sensor 102 based on the rainfall). Once the maximum value of the wiping frequency range is reached, the driver only needs to generate a high-speed signal by operating the wiper control terminal 103 or a rainstorm command by the central control display 105 to enable the wiper controller 101 to enter the rainstorm mode, providing convenience for the driver to enter the rainstorm mode.
[0053] When the wiper controller 101 is in the second wiping state, if the wiper controller 101 receives a rainstorm command sent by the central control display 105, the wiper controller 101 will enter the rainstorm mode. In the scenario of manual wiping (i.e., the scenario where the wiper 104 is controlled according to the height signal sent by the wiper control terminal 103), the driver only needs to generate a rainstorm command by operating the central control display 105 to put the wiper controller 101 into the rainstorm mode, which provides convenience for the driver.
[0054] Meanwhile, the central control display screen 105 has the highest priority, which enables the rainstorm command generated by the central control display screen 105 to put the wiper controller 101 into rainstorm mode in both automatic and manual wiping scenarios, ensuring the reliability of entering rainstorm mode.
[0055] In automatic wiping scenarios, the driver can enter the rainstorm mode by operating the wiper control terminal 103 (i.e., adjusting the wiper control terminal 103 to the high speed setting and generating a high speed signal). This eliminates the need for the driver to operate the central control display 105, further enhancing the driver's convenience and preventing the driver from being distracted by searching for and touching the rainstorm button on the central control display 105 to generate the rainstorm command, thus avoiding driving risks.
[0056] In manual wiping scenarios, the driver needs to trigger the rainstorm button on the central control display 105 to generate a rainstorm command, causing the wiper controller 101 to enter rainstorm mode. This ensures that the driver can only activate the wiper controller 101 into rainstorm mode through the central control display 105, preventing accidental activation due to other driver operations (such as frequent operation of the wiper control terminal 103). This guarantees that the wiper controller 101 operates entirely according to the driver's intentions in manual wiping scenarios, ensuring reliability in these scenarios.
[0057] In this embodiment, the wiper controller 101 is a device for operating and controlling the windshield wipers 104, typically located on the steering wheel or dashboard next to the driver's seat. The main function of the wiper controller 101 is to start, stop, and adjust the operation of the wipers 104 to clear rainwater, snow, or other debris from the windshield, thereby ensuring clear visibility for the driver and improving driving safety.
[0058] In this embodiment, the wiper controller 101 has the following functions: Start and Stop: By rotating or pushing a switch or button on the wiper controller 101, the driver can activate the wipers 104 to begin working and clear raindrops or other dirt from the windshield. Operating the switch or button again will stop the wipers 104 from working. Speed Adjustment: The wiper controller 101 typically allows the driver to adjust the speed of the wipers 104 to adapt to different levels of rainfall. Multiple speed options are usually available, including fast, medium, and slow. Rain Sensing Function Based on Rain Sensor 102: Some modern vehicles are equipped with rain-sensing wiper systems 104 that automatically adjust the speed of the wipers 104 based on the sensed rainfall intensity. This allows the wipers 104 to operate automatically when needed without manual driver intervention. Washing Function: The wiper controller 101 typically also includes a washer spray function, allowing the driver to spray washer fluid onto the windshield to help remove more stubborn dirt. The specific design and function of wiper controllers 101 may vary depending on the car manufacturer and model, but in general, they are key automotive safety devices that help keep the driver's vision clear and reduce the risks of driving in rain or inclement weather.
[0059] A wiper control lever is used as the wiper control terminal 103. The wiper control lever is a device used to operate and control the vehicle's wipers 104, typically located on the steering wheel or dashboard near the driver's seat. The lever is usually a rod-shaped object that the driver can rotate, push, or press switches or buttons on it to control the operation of the wipers 104. These operations include starting, stopping, adjusting speed, and controlling the washer function.
[0060] In this embodiment, the wiper control lever functions as follows: Start and Stop: By rotating or pushing a switch or button on the lever, the driver can activate the wipers 104 to begin working, clearing raindrops or other dirt from the windshield. Operating the switch or button again will stop the wipers 104. Speed Adjustment: The wiper control lever typically has multiple speed settings, allowing the driver to adjust the speed of the wipers 104 to suit different levels of rainfall. Speed settings typically include fast, medium, and slow. Washing Function: The lever usually also has a button or switch for activating the washer function of the wipers 104. Pressing this button will spray washer fluid onto the windshield, helping to remove more stubborn dirt. The specific design and function of the wiper control lever may vary depending on the car manufacturer and model, but they generally include the above-mentioned functions to help the driver maintain clear visibility in rainy or inclement weather, thereby improving driving safety.
[0061] Rain sensor 102 is a rain light sensor (RLS) that monitors the amount of rainwater on the windshield, monitors the lighting conditions, and provides control signals to the electrical system through circuit calculations.
[0062] 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 a rainstorm command via the body control module 106 based on the driver's click of the rainstorm button on the central control display screen 105. The wiper control terminal 103 generates automatic transmission signals and gear position signals via the body control module 106 based on the driver's automatic transmission operation, high gear signal, and non-high gear signal on the wiper control terminal 103. The gear position signals include high gear signals and non-high gear signals. The body control module 106 is the BCM, short for Body Control Module, a key component of the vehicle's electronic control system. It is primarily responsible for controlling the electrical equipment of various vehicle systems, such as lights, independent heaters, wipers, and windows. It can also communicate with the vehicle's in-vehicle communication network (CAN) and code spectrum to perform various sensing and control functions.
[0063] Windshield wipers 104 are used to clear rainwater, snow, and other debris from the windshield to ensure clear visibility for the driver and improve driving safety. Windshield wipers 104 typically consist of a rubber blade or brush that is mounted on the windshield and moved by an electric motor or manual operation to wipe away rainwater or other debris. In inclement weather conditions, windshield wipers 104 are crucial because they help drivers maintain good visibility and reduce the risk of accidents. In addition to front windshield wipers 104, some cars are also equipped with rear windshield wipers 104 for cleaning rainwater and dirt from the rear windshield.
[0064] Example 2:
[0065] This embodiment is a specific application scenario of the above embodiment one. Through this embodiment, the method provided by the present invention can be explained more clearly and specifically.
[0066] Below, we will discuss a windshield wiper control system that utilizes a windshield wiper control method in a new energy vehicle.
[0067] Taking the use of a car window wiper in heavy rain mode as an example, this embodiment will be used to specifically illustrate the method provided. It should be noted that this embodiment is merely exemplary and does not limit the scope of protection of this invention.
[0068] Please see Figure 1 and Figure 2This application provides a windshield wiper control method for new energy vehicles. By setting a rainstorm mode, the wiper controller can control the wipers to wipe the windshield at a safe frequency in key areas. That is, high-frequency wiping is performed in a small wiping area. This not only ensures that rainwater on the windshield is wiped away in time, thus ensuring clear visibility for the driver and avoiding accidents, but also shortens the wiper's stroke under high-frequency wiping by limiting the wiping range on the windshield, thereby reducing the risk of wiper damage.
[0069] This application provides a windshield wiper control method for a new energy vehicle, applied in the windshield wiper control system of the vehicle. The windshield wiper control system includes: a wiper controller 101, a rain sensor 102, a wiper control terminal 103, a wiper blade 104, and a central control display screen 105; the wiper controller 101 is connected to the rain sensor 102, the wiper control terminal 103, the wiper blade 104, and the central control display screen 105 respectively; the wiper blade 104 is used to wipe the windshield of the vehicle.
[0070] The methods include:
[0071] S201: When the wiper controller 101 is in the first wiping state, if the wiper controller 101 receives a high-speed signal sent by the wiper control terminal 103, or receives a rainstorm command sent by the central control display screen 105, the wiper controller 101 will enter the rainstorm mode; wherein, the first wiping state is the working state in which the wiper controller 101 controls the wiper 104 to wipe a designated area of the windshield according to the maximum value signal; the maximum value signal is the maximum value of the frequency in the wiping frequency range; the wiping frequency range is the frequency range used by the rain sensor 102 to determine the wiping frequency of the wiper 104 according to the rainfall in the environment where the car is located.
[0072] S202: When the wiper controller 101 is in the second wiping state, if the wiper controller 101 receives a rainstorm command sent by the central control display screen 105, the wiper controller 101 will enter the rainstorm mode. The second wiping state is the working state in which the wiper controller 101 controls the wiper 104 to wipe a designated area of the window according to the high-speed signal. The high-speed signal is sent by the wiper control terminal 103 and is a command message used to instruct the wiper 104 to wipe the window at a high-speed frequency. The rainstorm mode is used to instruct the wiper controller 101 to control the wiper 104 to wipe the key area of the window at a safe frequency. The value of the safe frequency is greater than or equal to the high-speed frequency, and the range of the key area is smaller than the designated area.
[0073] Optionally, when the wiper controller 101 is in the second wiping state, if it receives a rainstorm command from the front camera, the wiper controller 101 enters a rainstorm mode. The front camera generates a rainstorm signal if it detects that the light transmittance of the windshield of the new energy vehicle is lower than a preset light transmittance threshold. The light transmittance is the intensity of external light passing through the windshield and entering the interior of the new energy vehicle. In this embodiment, rain severely affects the driver's vision. Although wipers are installed on the windshield, rainwater reduces light transmittance, significantly shortening the visible distance and reducing visibility. This makes it very difficult to correctly observe and judge oncoming vehicles and pedestrians, as well as to correctly choose a driving route. Therefore, when the front camera detects that the light transmittance of the windshield has decreased to the light transmittance threshold, it sends a rainstorm command to the wiper controller 101, causing the wiper controller 101 to enter rainstorm mode to ensure clear camera view and thus protect the safety of pedestrians and vehicles. S203: If the wiper controller 101 determines that the current vehicle speed exceeds the vehicle speed threshold and / or determines that the rainfall in the environment where the vehicle is located is lower than the preset rainfall threshold, the wiper controller 101 will stop the rainstorm mode.
[0074] S204: If the wiper controller 101 determines that the current temperature exceeds the temperature threshold, the wiper controller 101 will stop the rainstorm mode.
[0075] S205: If it is determined that the wiper controller 101 was in the first wiping state before entering the rainstorm mode, the wiper controller 101 shall re-enter the first wiping state; if it is determined that the wiper controller 101 was in the second wiping state before entering the rainstorm mode, the wiper controller 101 shall re-enter the second wiping state.
[0076] S206: If it is determined that the wiper controller 101 is in the first wiping state before entering the rainstorm mode, the first wiping frequency is obtained from the preset buffer component. The wiper controller 101 then controls the wipers 104 to wipe the designated area of the windshield according to the first wiping frequency. The first wiping frequency is less than the maximum frequency represented by the maximum value signal; for example, if the maximum frequency is 60 cpm, the first wiping frequency is 40 cpm. Cpm is an abbreviation for count per minute. Hz refers to the count per second, so the conversion is 1 CPM = (1 / 60) Hz, or 1 Hz = 60 CPM. Frequency is the number of times a periodic change is completed per unit time; it is a quantity describing the frequency of periodic motion, commonly represented by the symbol f or ν, and its unit is one second, with the symbol s⁻¹.
[0077] If it is determined that the wiper 101 is in the second wiping state before entering the rainstorm mode, the second wiping frequency is obtained from the preset buffer component, and the wiper controller 101 controls the wiper 104 to wipe the designated area of the windshield according to the second wiping frequency; wherein, the second wiping frequency is less than the high-speed frequency represented by the high-speed signal; for example, the high-speed frequency is 70 cpm, and the second wiping frequency is 45 cpm.
[0078] S207: If the wiper controller 101 receives a central control normal signal sent by the central control display screen 105, the wiper controller 101 stops the rainstorm mode and controls the wiper 104 to wipe the windshield according to the central control normal frequency in the central control normal signal; wherein, the central control normal signal is used to instruct the wiper controller 101 to control the wiper 104 to wipe a specified area at a frequency lower than the maximum frequency value; the central control normal frequency is generated by the central control display screen 105 and is a frequency value lower than the maximum frequency value. For example, the central control normal signal is an electrical signal generated by the user to control the wipers by operating the wiper control page on the central control display screen. The user can click the high-speed wiper button, medium-speed wiper button, low-speed wiper button, etc. on the central control display screen to generate central control normal signals with different central control normal frequencies (high-speed wiper frequency, medium-speed wiper frequency, low-speed wiper frequency).
[0079] S208: If the wiper controller 101 receives a central control stop signal sent by the central control display screen 105, the wiper controller 101 controls the wiper 104 to rotate to the initial position and stops the wiper 104 from wiping. The initial position is the position of the wiper when it is started, which is usually the position where the wiper blade is parallel to the bottom edge of the window.
[0080] S209: If the wiper controller 101 receives a terminal normal signal sent by the wiper control terminal 103, the wiper controller 101 stops the heavy rain mode and controls the wiper 104 to wipe the windshield according to the terminal normal frequency in the terminal normal signal; wherein, the terminal normal signal is used to instruct the wiper controller 101 to control the wiper 104 to wipe a specified area at a frequency lower than the maximum frequency value; the terminal normal frequency is generated by the wiper control terminal 103 and is a frequency value lower than the maximum frequency value. For example, the terminal normal signal is an electrical signal generated by the user operating the control lever of the wiper control terminal to control the wipers. The user can generate terminal normal signals with different terminal normal frequencies (high-speed wiping frequency, medium-speed wiping frequency, low-speed wiping frequency) by moving the control lever and clicking on the terminal display screen to select high-speed wiping, medium-speed wiping, low-speed wiping, etc.
[0081] S210: If the wiper controller 101 receives a terminal stop signal sent by the terminal display screen 105, the wiper controller 101 controls the wiper 104 to rotate to the initial position and stops the wiper 104 from wiping. The initial position is the position of the wiper when it is started, typically where the wiper blade is parallel to the bottom edge of the window. In this example, by setting a heavy rain mode, the wiper controller 101 can control the wiper 104 to wipe the window at a safe frequency within a critical area. That is, high-frequency wiping within a smaller wiping area not only ensures timely wiping of rainwater on the window, guaranteeing clear visibility for the driver and preventing accidents, but also reduces the risk of damage by limiting the wiping range of the wiper 104 on the window and shortening its travel under high-frequency wiping.
[0082] When the wiper controller 101 is in the first wiping state, if it receives a high-speed signal from the wiper control terminal 103 or a rainstorm command from the central control display 105, the wiper controller 101 will enter the rainstorm mode. This allows the wiper controller 101 to enter the rainstorm mode in automatic wiping scenarios (i.e., scenarios where the wiper frequency of the wiper 104 is determined by the rain sensor 102 based on the rainfall). Once the maximum value of the wiping frequency range is reached, the driver only needs to generate a high-speed signal by operating the wiper control terminal 103 or a rainstorm command by the central control display 105 to enable the wiper controller 101 to enter the rainstorm mode, providing convenience for the driver to enter the rainstorm mode.
[0083] When the wiper controller 101 is in the second wiping state, if the wiper controller 101 receives a rainstorm command sent by the central control display 105, the wiper controller 101 will enter the rainstorm mode. In the scenario of manual wiping (i.e., the scenario where the wiper 104 is controlled according to the height signal sent by the wiper control terminal 103), the driver only needs to generate a rainstorm command by operating the central control display 105 to put the wiper controller 101 into the rainstorm mode, which provides convenience for the driver.
[0084] Meanwhile, the central control display screen 105 has the highest priority, which enables the rainstorm command generated by the central control display screen 105 to put the wiper controller 101 into rainstorm mode in both automatic and manual wiping scenarios, ensuring the reliability of entering rainstorm mode.
[0085] In this embodiment, the wiper controller 101 controls the rotational 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, based on the maximum frequency, high-speed frequency, central control normal frequency, terminal normal frequency, first wiper frequency, or second wiper frequency. This controls the wiper frequency, ensuring that the wiper frequency corresponds to the maximum frequency, high-speed frequency, central control normal frequency, terminal normal frequency, first wiper frequency, or second wiper frequency. Pulse width modulation (PWM) technology is used to adjust the duty cycle of the pulse current. PWM is a method of digitally encoding analog signal levels. By using a high-resolution counter, the duty cycle of the square wave is modulated to encode the level of a specific analog signal, thereby adjusting the duty cycle of the current output from the power supply to the motor. In automatic wiping scenarios, the driver can enter the rainstorm mode by operating the wiper control terminal 103 (i.e., adjusting the wiper control terminal 103 to the high speed setting and generating a high speed signal). This eliminates the need for the driver to operate the central control display 105, further enhancing the driver's convenience and preventing the driver from being distracted by searching for and touching the rainstorm button on the central control display 105 to generate the rainstorm command, thus avoiding driving risks.
[0086] In manual wiping scenarios, the driver needs to trigger the rainstorm button on the central control display 105 to generate a rainstorm command, causing the wiper controller 101 to enter rainstorm mode. This ensures that the driver can only activate the wiper controller 101 into rainstorm mode through the central control display 105, preventing accidental activation due to other driver operations (such as frequent operation of the wiper control terminal 103). This guarantees that the wiper controller 101 operates entirely according to the driver's intentions in manual wiping scenarios, ensuring reliability in these scenarios.
[0087] In this embodiment, the wiper controller 101 is a device for operating and controlling the windshield wipers 104, typically located on the steering wheel or dashboard next to the driver's seat. The main function of the wiper controller 101 is to start, stop, and adjust the operation of the wipers 104 to clear rainwater, snow, or other debris from the windshield, thereby ensuring clear visibility for the driver and improving driving safety.
[0088] In this embodiment, the wiper controller 101 has the following functions: Start and Stop: By rotating or pushing a switch or button on the wiper controller 101, the driver can activate the wipers 104 to begin working and clear raindrops or other dirt from the windshield. Operating the switch or button again will stop the wipers 104 from working. Speed Adjustment: The wiper controller 101 typically allows the driver to adjust the speed of the wipers 104 to adapt to different levels of rainfall. Multiple speed options are usually available, including fast, medium, and slow. Rain Sensing Function Based on Rain Sensor 102: Some modern vehicles are equipped with rain-sensing wiper systems 104 that automatically adjust the speed of the wipers 104 based on the sensed rainfall intensity. This allows the wipers 104 to operate automatically when needed without manual driver intervention. Washing Function: The wiper controller 101 typically also includes a washer spray function, allowing the driver to spray washer fluid onto the windshield to help remove more stubborn dirt. The specific design and function of wiper controllers 101 may vary depending on the car manufacturer and model, but in general, they are key automotive safety devices that help keep the driver's vision clear and reduce the risks of driving in rain or inclement weather.
[0089] A wiper control lever is used as the wiper control terminal 103. The wiper control lever is a device used to operate and control the vehicle's wipers 104, typically located on the steering wheel or dashboard near the driver's seat. The lever is usually a rod-shaped object that the driver can rotate, push, or press switches or buttons on it to control the operation of the wipers 104. These operations include starting, stopping, adjusting speed, and controlling the washer function.
[0090] In this embodiment, the wiper control lever functions as follows: Start and Stop: By rotating or pushing a switch or button on the lever, the driver can activate the wipers 104 to begin working, clearing raindrops or other dirt from the windshield. Operating the switch or button again will stop the wipers 104. Speed Adjustment: The wiper control lever typically has multiple speed settings, allowing the driver to adjust the speed of the wipers 104 to suit different levels of rainfall. Speed settings typically include fast, medium, and slow. Washing Function: The lever usually also has a button or switch for activating the washer function of the wipers 104. Pressing this button will spray washer fluid onto the windshield, helping to remove more stubborn dirt. The specific design and function of the wiper control lever may vary depending on the car manufacturer and model, but they generally include the above-mentioned functions to help the driver maintain clear visibility in rainy or inclement weather, thereby improving driving safety.
[0091] Rain sensor 102 is a rain light sensor (RLS) that monitors the amount of rainwater on the windshield, monitors the lighting conditions, and provides control signals to the electrical system through circuit calculations.
[0092] 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 a rainstorm command via the body control module 106 based on the driver's click of the rainstorm button on the central control display screen 105. The wiper control terminal 103 generates automatic transmission signals and gear position signals via the body control module 106 based on the driver's automatic transmission operation, high gear signal, and non-high gear signal on the wiper control terminal 103. The gear position signals include high gear signals and non-high gear signals. The body control module 106 is the BCM, short for Body Control Module, a key component of the vehicle's electronic control system. It is primarily responsible for controlling the electrical equipment of various vehicle systems, such as lights, independent heaters, wipers, and windows. It can also communicate with the vehicle's in-vehicle communication network (CAN) and code spectrum to perform various sensing and control functions.
[0093] Windshield wipers 104 are used to clear rainwater, snow, and other debris from the windshield to ensure clear visibility for the driver and improve driving safety. Windshield wipers 104 typically consist of a rubber blade or brush that is mounted on the windshield and moved by an electric motor or manual operation to wipe away rainwater or other debris. In inclement weather conditions, windshield wipers 104 are crucial because they help drivers maintain good visibility and reduce the risk of accidents. In addition to front windshield wipers 104, some cars are also equipped with rear windshield wipers 104 for cleaning rainwater and dirt from the rear windshield.
[0094] If the vehicle speed sensor detects that the current vehicle speed exceeds the speed threshold and / or if it is determined that the rainfall in the vehicle's environment is lower than the preset rainfall threshold, it means that the vehicle can clear the rainwater off the windows at its current speed. In this case, if the vehicle is still in rain mode, it will cause interference to the driver. Therefore, the rain mode will be stopped.
[0095] If 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. In order to avoid damage to the wiper 104, the rain mode will be stopped to ensure the safety of the wiper 104.
[0096] If the wiper controller 101 receives a normal signal from the central control display 105, it means that 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 the rainstorm mode exit.
[0097] After exiting the rainstorm mode, the car may still need to continue wiping. To ensure that the driver's vision is not obstructed after exiting the rainstorm mode, this example uses the central control conventional signal to instruct the wiper controller 101 to control the wiper 104 to wipe the windshield at a frequency lower than the maximum frequency value.
[0098] Sometimes, when driving at high speeds, it is inconvenient for the driver to operate the central control display screen 105. The driver can generate a normal terminal signal by operating the wiper control terminal 103 to make the wiper controller 101 exit the rainstorm mode. In order to ensure that the driver's vision is not interfered with after exiting the rainstorm mode, this example instructs the wiper controller 101 to control the wiper 104 to wipe the windshield at a frequency lower than the maximum frequency value through the normal terminal signal.
[0099] In a preferred embodiment, the wiper controller 101 is in a first wiping state, including:
[0100] If the wiper controller 101 detects that the rain sensor 102 is turned on, the wiper controller 101 sends an automatic mode command to the rain sensor 102.
[0101] Rain sensor 102 detects the amount of rainfall in the environment where the car is located according to the automatic transmission command, and generates a frequency command based on the amount of rainfall. Rain sensor 102 sends the frequency command to wiper controller 101.
[0102] The wiper controller 101 controls the wipers 104 to wipe the car windows according to the frequency command, and determines that the wiper controller 101 is in the first wiping state.
[0103] In this example, the driver operates the wiper control terminal 103 to automatic mode, activating the rain sensor 102. If the wiper controller 101 detects that the rain sensor 102 is activated, it will enter the automatic wiping scenario. At this time, the wiper sensor will detect the rainfall in the vehicle's environment and generate a wiping frequency that the wiper 104 should use to wipe the designated area based on the rainfall. The wiper controller 101 will then send a frequency command containing the wiping frequency to the wiper controller 101, which will control 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 windshield wiping mode in the automatic wiping scenario.
[0104] If the vehicle speed sensor detects that the current vehicle speed exceeds the speed threshold and / or if it is determined that the rainfall in the vehicle's environment is lower than the preset rainfall threshold, it means that the vehicle can clear the rainwater off the windows at its current speed. In this case, if the vehicle is still in rain mode, it will cause interference to the driver. Therefore, the rain mode will be stopped. At the same time, by setting the rainfall threshold, it is indicated that if the rainfall in the vehicle's environment is less than the rainfall threshold, it means that the vehicle does not need to remain in rain mode.
[0105] If 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. In order to avoid damage to the wiper 104, the rain mode will be stopped to ensure the safety of the wiper 104.
[0106] If the wiper controller 101 receives a normal signal from the central control display 105, it means that 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 the rainstorm mode exit.
[0107] After exiting the rainstorm mode, the car may still need to continue wiping. To ensure that the driver's vision is not obstructed after exiting the rainstorm mode, this example uses the central control conventional signal to instruct the wiper controller 101 to control the wiper 104 to wipe the windshield at a frequency lower than the maximum frequency value.
[0108] In this embodiment, the priority of the central control conventional signal is higher than that of the conventional signal.
[0109] Sometimes, when driving at high speeds, it is inconvenient for the driver to operate the central control display screen 105. The driver can generate a normal terminal signal by operating the wiper control terminal 103 to make the wiper controller 101 exit the rainstorm mode. In order to ensure that the driver's vision is not interfered with after exiting the rainstorm mode, this example instructs the wiper controller 101 to control the wiper 104 to wipe the windshield at a frequency lower than the maximum frequency value through the normal terminal signal.
[0110] If the wiper controller 101 is in the first wiping state before entering the rainstorm mode, the wiper controller 101 will re-enter the first wiping state after exiting the rainstorm mode. This ensures that when entering the rainstorm mode from the automatic wiping scenario and then exiting the rainstorm mode again, the wiper controller 101 will re-enter the automatic wiping scenario, thus ensuring the consistency of the wiping scenario.
[0111] If the wiper controller 101 is in the first wiping state before entering the rainstorm mode, the wiper controller 101 will re-enter the first wiping state after exiting the rainstorm mode. This ensures that when entering the rainstorm mode from the manual wiping scenario and then exiting the rainstorm mode again, the wiper controller 101 will re-enter the manual wiping scenario, thus ensuring the consistency of the wiping scenario.
[0112] In a preferred embodiment, the wiper controller 101 is in a second wiping state, including:
[0113] If the wiper controller 101 does not detect that the rain sensor 102 is turned on, but detects the gear signal sent by the wiper control terminal 103, the wiper controller 101 controls the wiper 104 to wipe the windshield according to the frequency in the gear signal.
[0114] The gear signal is one of a high-speed gear signal and at least one non-high-speed gear signal; the non-high-speed gear signal is a command sent by the wiper control terminal 103 to instruct the wiper 104 to wipe the windshield at a non-high-speed frequency; the non-high-speed frequency is lower than the high-speed frequency.
[0115] In this example, the driver will operate the wiper control terminal 103 to a high speed or a non-high speed. The rain sensor 102 will not be turned on. If the wiper controller 101 does not detect that the rain sensor 102 is turned off, the wiper controller 101 will enter the manual wiping scenario. The wiper controller 101 controls the wiper 104 to wipe according to the speed signal sent by the wiper control terminal 103.
[0116] For example, the high-speed frequency is 60 cpm, and the non-high-speed frequencies include 50 cpm, 40 cpm, 30 cpm, and 20 cpm. If the frequency of the received gear signal is 60 cpm, then the received gear signal is determined to be a high-speed gear signal; if the frequency of the received gear signal is any one of 50 cpm, 40 cpm, 30 cpm, and 20 cpm, then the received gear signal is determined to be a non-high-speed gear signal.
[0117] In a preferred embodiment, the wiper control system further includes: a vehicle speed sensor and a temperature sensor; the vehicle speed sensor is connected to the wiper controller 101 and is used to detect the vehicle speed; the temperature sensor is connected to the wiper controller 101 and is used to detect the temperature of the wiper 104.
[0118] Before the wiper controller 101 enters the heavy rain mode, the method also includes:
[0119] The wiper controller 101 triggers the vehicle speed sensor to provide feedback on the vehicle's current speed;
[0120] If the wiper controller 101 determines that the current vehicle speed has not exceeded the preset vehicle speed threshold, the wiper controller 101 will trigger the temperature sensor to provide feedback on the current temperature of the wiper 104.
[0121] If the wiper controller 101 determines that the current temperature has not exceeded the preset temperature threshold, the wiper controller 101 will enter the rainstorm mode.
[0122] In this example, in heavy rain, when the car is traveling at high speed, the rainwater on the windows will be washed away by the high speed. If the heavy rain mode is activated at this time, the wipers 104 will obstruct the driver's vision by wiping key areas. Therefore, if the current speed does not exceed the speed threshold, it means that the car cannot wash away the rainwater on the windows at the current speed, and the wiper controller 101 can enter the heavy rain mode. If the current speed exceeds the speed threshold, it means that the car can wash away the rainwater on the windows at the current speed, and the wiper controller 101 will not need to enter the heavy rain mode.
[0123] Because the windshield wipers 104 in heavy rain mode will wipe the windshield at a high frequency in key areas, the windshield wipers 104 will have a heavy operating load in heavy rain mode. In order to prevent the windshield wipers 104 from overheating and burning out, the current temperature of the windshield wipers 104 is collected by a temperature sensor. If the current temperature does not exceed the temperature threshold, the windshield wiper controller 101 can directly enter the heavy rain mode. If the current temperature exceeds the temperature threshold, the windshield wiper controller 101 is prevented from entering the heavy rain mode to protect the windshield wipers 104.
[0124] For example, assuming the temperature threshold is 80°C, then if the current temperature is not greater than 80°C, the rainstorm mode can be entered; if the current temperature exceeds 80°C, the rainstorm mode cannot be entered.
[0125] In a preferred embodiment, the wiper control system further includes: a configuration module 107, which is connected to the wiper controller 101;
[0126] The wiper controller 101 then enters heavy rain mode, including:
[0127] If the wiper controller 101 extracts the rainstorm frequency parameter from the configuration module 107, it sets the rainstorm frequency to a safe frequency; wherein the rainstorm frequency parameter is greater than or equal to the maximum frequency value.
[0128] If the wiper controller 101 does not extract the rainstorm frequency parameter from the configuration module 107, it sets the maximum frequency value as the safe frequency.
[0129] The wiper controller 101 extracts the upper angle parameter (URP-A) and lower angle parameter (LRP+A) from the configuration module 107, and controls the wiper 104 to use the lower angle parameter as the lower stop point and the upper angle parameter as the upper stop point to wipe the windshield at a safe frequency; the upper and lower stop points are the critical areas on the windshield.
[0130] In this example, the configuration module 107 can set the rainstorm frequency parameter. If the wiper controller 101 enters the rainstorm mode, the rainstorm frequency parameter is extracted by the configuration module 107 and set as a safe frequency. The wiper then wipes the windshield at the safe frequency. Alternatively, the configuration module 107 can be left unset. In this case, the maximum frequency value in the configuration module 107 is used as the safe frequency, and the wiper then wipes the windshield at this safe frequency to ensure that the wiper 104 wipes the windshield at a high frequency.
[0131] Meanwhile, by setting upper and lower angle parameters, key areas can be identified to achieve customized management of these key areas.
[0132] For example, if the configuration module 107 only records the wiping frequency range [20cpm, 60cpm], then 60cpm will be used as the safe frequency. If the configuration module 107 not only records the wiping frequency range [20cpm, 60cpm], but also records the rainstorm frequency parameter: 70cpm, then 70cpm will be used as the safe frequency.
[0133] The configuration module 107 defines the angle range of a specified area, for example: [LRP: 0°, URP: 90°], where LRP is the lower limit of the specified area and URP is the upper limit of the specified area. Therefore, the wiper controller 101 will control the wiper 104 to wipe the windshield within an angle range of 0°-90°, which is the specified area.
[0134] The upper angle parameter in the configuration module 107 is 20° and the lower angle parameter is 70°. Therefore, the wiper controller 101 will control the wiper 104 to wipe the windshield within an angle range of 20°-70°. This wiping range is the critical area.
[0135] In a preferred embodiment, the wiper control system further includes: a fault detection module 108; the fault detection module 108 is connected to the wiper controller 101, and the fault detection module 108 is used to detect whether the vehicle and the wiper 104 are malfunctioning.
[0136] After the wiper controller 101 enters the heavy rain mode, the method also includes:
[0137] If the wiper controller 101 receives a fault signal sent by the fault detection module 108, the wiper controller 101 will stop the rain mode; wherein, the fault signal indicates that the car and / or the wiper 104 has malfunctioned.
[0138] In this example, if the fault detection module 108 detects a fault in the car and / or the windshield wiper 104, and the windshield wiper controller 101 continues to be in rain mode, it will cause the car and / or the windshield wiper 104 to continue to be damaged, resulting in the expansion of the fault of the car and / or the windshield wiper 104.
[0139] Therefore, once the fault detection module 108 detects a fault in the car and / or the windshield wipers 104, it exits the rainstorm mode to prevent the fault from spreading or worsening.
[0140] The fault detection module 108 (commonly referred to as a vehicle diagnostic module) is an electronic or software tool used to monitor and detect vehicle systems, engines, and other critical components. These modules are an important part of modern automobiles, designed to identify and record vehicle performance problems, faults, and error codes.
[0141] The main functions of the fault detection module 108 include: Diagnosis: Monitoring various systems of the vehicle, such as the engine, transmission, braking system, and emission system, to detect any abnormalities or malfunctions. Recording fault codes: When the module detects a problem, it generates error codes, called fault codes, to indicate the nature and location of the problem. These fault codes can be used by technicians or vehicle owners for diagnosis and repair. Real-time data monitoring: The module can typically monitor and record real-time vehicle data, such as vehicle speed, engine temperature, oil pressure, and air-fuel ratio, to help diagnose problems and optimize performance. Driver alerts: Some fault detection modules 108 can send warning signals to the driver, such as the engine malfunction indicator light or other warning lights, indicating that a problem needs repair. Repair suggestions: Some advanced vehicle diagnostic modules can also provide repair suggestions, including guidance for owners or technicians on how to repair specific problems. These modules typically communicate with the vehicle's electronic systems through the vehicle's diagnostic interface, such as the OBD-II (On-Board Diagnostics II) interface. Automakers use different standards and protocols to implement these functions; therefore, different brands and models of vehicles may use different fault detection modules 108. These modules are crucial for quickly and accurately locating and resolving vehicle problems, contributing to improved driving safety and vehicle performance.
