Description

Technical Field

[0001] The present application relates to the field of vehicle defrosting technology, and in particular to a wiper defrosting method, system, intelligent terminal and storage medium. Background Art

[0002] A windshield wiper, also known as a rain wiper, water wiper, water paddle or windshield wiper, is a device used to scrape off raindrops and dust attached to the windshield of a vehicle, which can improve the driver's visibility and increase driving safety.

[0003] In the related art, the wiper lacks the temperature regulation function, which results in the wiper only being able to remove rain and dust from the windshield. In cold weather, frost and ice are easily formed on the windshield of a car. The driver needs to remove the frost on the windshield before driving the car to ensure a good view. At this time, the frost can only be removed by using auxiliary tools such as an ice scraper and car defrost. First, spray the car defrost on the windshield. When the frost melts slightly and loosens, use the ice scraper to scrape the loose frost from the windshield.

[0004] Regarding the above-mentioned related technologies, because the wipers lack the temperature regulation function, when frost appears on the windshield, the driver can only use auxiliary tools such as ice scrapers and car defrost to remove the frost on the windshield. The process of removing frost is cumbersome, which makes it inconvenient to remove frost from the windshield. There is still room for improvement. Summary of the invention

[0005] In order to improve the convenience of defrosting a windshield, the present application provides a wiper defrosting method, system, intelligent terminal and storage medium.

[0007] By adopting the above technical solution, after receiving the defrost trigger information, the wiper is controlled to heat and swing, so as to melt and remove the frost on the windshield, and the defrost image information is detected. When it is determined that the defrost image information meets the requirements of the no-frost image information or the shutdown trigger information is received, the wiper is controlled to reset and shut down, so that there is no need for personnel to use complex defrosting agents, scraper plates and other tools to perform tedious defrosting work, thereby improving the convenience of defrosting the windshield.

[0009] By adopting the above technical scheme, the wiper heating position information is determined according to the frost parameter information and the heating position relationship information, so that the wiper is accurately controlled to heat only the position that needs to be defrosted, and the position heating temperature information is determined according to the frost parameter information and the thickness-temperature relationship information, so that the wiper can ensure the efficiency of defrosting while taking into account safety, thereby improving the convenience of defrosting the wiper.

[0011] By adopting the above technical scheme, the coordinate system is mapped to the windshield image information, so as to identify the frost feature information and obtain the frost position information, and then determine the frost associated position information based on the frost position information and the swing position relationship information, so as to determine the position on a swing arc as the associated position based on the principle of wiper swing, and then determine the maximum ice thickness at the associated position as the frost thickness information, so as to ensure that the wiper can effectively remove the frost on the arc, thereby improving the accuracy of determining the frost parameter information.

[0012] Optionally, the step of obtaining the ice thickness information at the location according to the frost-associated location information includes: Obtaining external brightness information of the windshield; Determine whether the external brightness information meets the preset light transmittance brightness information requirements; If it meets the requirements, the preset transmittance detection trigger information is output; If it does not meet the requirements, the preset vehicle lights are turned on for fill light, and preset transmittance detection trigger information is output; According to the transmittance detection trigger information and the preset single detection area information, the transmittance of the position corresponding to the frost associated position information is detected to determine the transmittance detection information; Determine single-time detection thickness information according to transmittance detection information and preset transmittance-thickness relationship information; The single detection thickness information and the frost associated position information are associated to generate the position ice thickness information.

[0013] By adopting the above technical scheme, the transmittance of the windshield is detected to obtain transmittance detection information, so as to determine the frost thickness of the windshield at that location based on the relationship between frost layers of different thicknesses and transmittance and the detected transmittance analysis, thereby improving the accuracy of the ice thickness information at the determined location.

[0014] Optionally, the step of controlling the wiper heating swing to remove frost on the windshield according to the wiper heating position information, the position heating temperature information and the defrosting trigger information includes: Analyzing the defrost trigger information to determine the wiper swing speed information; Analyze the position heating temperature information, the swing speed information and the preset reference speed information to determine the actual position temperature information; The wiper heating swing is controlled according to the wiper heating position information and the actual position temperature information to remove frost on the windshield.

[0015] By adopting the above technical scheme, the gain ratio is determined according to the swing speed information and the reference speed information, and the actual position temperature information is determined according to the gain ratio and the position heating temperature information. Therefore, when the swing speed of the wiper is different, the frost is heated at an appropriate temperature, thereby improving the efficiency of removing frost.

[0017] By adopting the above technical solution, when the melting trigger information is received, the detection angle information and the detection position information are called, and the starting sequence number information for removing frost at the position is determined according to the detection position information, so as to start the corresponding water absorption device according to the starting sequence number information. When the swing angle reaches the detection angle information, the water absorption device is controlled to absorb the melted water, so as to prevent the water from freezing again, thereby improving the effect of the wiper in removing frost.

[0018] Optionally, before obtaining the defrost triggering information of the wiper, an antifreeze step of the wiper is also included, and the specific steps include: Get the wiper status detection information; Determine whether the status detection information meets the preset upright status information requirements; If it is in compliance, then continue to obtain the wiper status detection information for cyclic judgment; If not, obtain the ambient temperature information; Determine constant temperature power information according to the ambient temperature information and preset temperature-power relationship information; The wiper heating is controlled based on the thermostatic power information to prevent the wipers from icing up.

[0019] By adopting the above technical scheme, when the state detection information of the wiper does not meet the requirements of the upright state information, the constant temperature power information for keeping the wiper from freezing is determined according to the ambient temperature information, thereby controlling the heating of the wiper according to the constant temperature power information to prevent the wiper from freezing and causing the wiper to be unable to normally remove frost on the windshield, thereby ensuring normal frost removal.

[0034] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 7 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] The embodiment of the present application discloses a method for removing frost on a windshield by using a wiper, and specifically discloses a processing terminal and a wiper. The processing terminal and the wiper are connected by a data wire to realize data interaction and control. After the processing terminal receives defrost trigger information, the processing terminal controls the wiper to heat and swing, thereby heating and scraping off the frost on the windshield, and detects de-icing image information. When the processing terminal determines that the de-icing image information meets the requirements of no-frost image information or receives a shutdown trigger information, the wiper is controlled to reset and stop heating and swinging, so that personnel no longer need to manually operate defrost agents and auxiliary tools such as scraper plates to remove frost, thereby improving the convenience of de-icing the windshield.

[0036] Reference Figure 1 The present application discloses a wiper defrosting method, comprising the following steps: Step S100: Obtaining defrost triggering information of the wiper.

[0037] Among them, the defrost trigger information refers to the trigger data for starting to remove frost on the windshield, which is sent to the processing terminal after the personnel presses the defrost button on the vehicle's central control platform.

[0038] Step S101: Controlling the wiper to heat and swing according to defrost trigger information to remove frost on a preset windshield, and obtaining defrost image information of the windshield.

[0039] After the processing terminal receives the defrost trigger information, the processing terminal responds to the defrost trigger information to control the wiper to heat and swing to melt the frost on the windshield and scrape it off. The specific method is as follows: Figure 2 The steps are performed and the defrosting image information of the windshield is detected to provide data support for the subsequent determination of whether to continue defrosting.

[0040] The windshield refers to the glass used for windshield on the car, including the front windshield and the rear windshield. The defrosting image information refers to the image of the windshield during the defrosting process, which is captured by a camera in the car and sent to the processing terminal.

[0041] Step S102: determining whether the defrost image information meets the preset requirement of non-frost image information.

[0042] The frost-free image information refers to image data showing that there is no frost on the windshield. The requirement for the frost-free image information refers to consistency of image features corresponding to the frost-free image information, which is stored in the processing terminal by the operator.

[0043] By processing the terminal, it is determined whether the image features corresponding to the defrost image information are consistent with the image features corresponding to the frost-free image information, thereby determining whether the wiper has completely scraped off the frost on the windshield, providing data support for the subsequent determination of whether to continue scraping off the frost on the windshield.

[0044] Step S1021: If it is met, the wiper is controlled to reset and the heating and swinging are stopped, and the defrost trigger information is continuously obtained for cyclic judgment.

[0045] Among them, if the processing terminal determines that the image features corresponding to the frost removal image information are consistent with the image features corresponding to the frost-free image information, it means that the wiper has scraped off all the frost on the windshield. Therefore, the wiper is controlled to reset and stop the heating and swinging, and the defrost trigger information is continued to be detected, so as to continuously monitor whether the personnel need defrosting.

[0046] Step S1022: If not, obtain the wiper closing trigger information.

[0047] Among them, if the processing terminal determines that the image features corresponding to the frost removal image information are inconsistent with the image features corresponding to the frost-free image information, it means that the frost on the windshield has not been completely removed. Therefore, the wiper is continued to be controlled to heat and swing to remove the frost on the windshield. At the same time, the wiper closing trigger information is collected to provide data support for the subsequent control of the wiper shutdown.

[0048] The shutdown trigger information refers to the trigger data for controlling the shutdown of the wipers. After a person presses the shutdown button on the vehicle's central control platform, the shutdown trigger information is sent to the processing terminal.

[0049] Step S103: Control the wiper to reset and stop heating and oscillating according to the shutdown trigger information.

[0050] Among them, after the processing terminal receives the shutdown trigger information, it indicates that the personnel do not need the wipers to remove frost, so the wipers are controlled to reset and stop heating and swinging, so as to prepare for the next start.

[0051] Reference Figure 2 The step of controlling the wiper to heat and swing according to the defrost trigger information to remove frost on the preset windshield includes: Step S200: acquiring frost parameter information of the windshield based on the defrost trigger information; the frost parameter information is characterized by frost position and frost thickness.

[0052] After the processing terminal receives the defrost trigger information, the frost parameter information of the windshield is detected to provide data support for the subsequent specific control of the wiper. The frost parameter information refers to the location and thickness data of the frost on the windshield. For specific acquisition methods, refer to Figure 3 steps.

[0053] Step S201: determining wiper heating position information according to frost parameter information and preset heating position relationship information.

[0054] Among them, the heating position relationship information refers to a database that stores the correspondence between frost positions and heating positions. Due to the arc swing law of the wiper, different positions on the windshield are heated by corresponding positions on the wiper. Therefore, the frost positions are corresponded one by one with the heating positions of the wiper and stored in the database to form heating position relationship information.

[0055] The wiper heating position information refers to the position on the wiper where heating needs to start. The processing terminal inputs the frost position corresponding to the frost parameter information into the database corresponding to the heating position relationship information for matching and output.

[0056] Step S202: determining the position heating temperature information of the wiper according to the frost parameter information and the preset thickness-temperature relationship information.

[0057] Among them, the thickness-temperature relationship information refers to a database that stores the corresponding relationship between frost thickness and heating temperature. The two are proportional, that is, the thicker the frost thickness, the higher the heating temperature. The proportional coefficient between the two is determined by the operator according to the actual situation, and the two are stored in the database after one-to-one correspondence to form thickness-temperature relationship information.

[0058] The position heating temperature information refers to the temperature that the wiper should have at different heating positions. The processing terminal inputs the frost thickness corresponding to the frost parameter information into the database corresponding to the thickness-temperature relationship information to obtain the temperature value, and then calls the wiper heating position corresponding to the frost position in the frost parameter information, and associates the temperature value with the wiper position to obtain the temperature that the specific position on the wiper should have.

[0059] Step S203: Controlling the wiper heating swing to remove frost on the windshield according to the wiper heating position information, the position heating temperature information and the defrosting trigger information.

[0060] After the processing terminal obtains the wiper heating position information and the position heating temperature information, the wiper heating swing is controlled according to the wiper heating position information, the position heating temperature information and the defrosting trigger information. The specific method is as follows: Figure 5 The steps are followed to control the wiper to heat the correct position at the appropriate temperature, and to remove frost on the windshield quickly and accurately.

[0061] Reference Figure 3 The step of obtaining frost parameter information of the windshield based on the defrost trigger information includes: Step S300: Acquire windshield image information based on defrost trigger information.

[0062] The windshield image information refers to the image of the windshield before defrosting. After the processing terminal receives the defrost trigger information, the processing terminal controls the camera in the car to take a picture of the windshield and sends it to the processing terminal.

[0063] Step S301: Analyze the windshield image information, a preset coordinate system and preset frost feature information to determine frost position information.

[0064] The coordinate system refers to a plane coordinate system used to specify different positions of the windshield. Frost feature information refers to image features representing frost. Frost position information refers to the specific position coordinates of frost on the windshield. The processing terminal identifies the frost feature information in the image corresponding to the windshield image information according to the trained convolutional neural network, and then maps the coordinate system to the image, and then identifies the coordinates of the frost features in the coordinate system to obtain the frost position information.

[0065] Step S302: determining frost-associated position information according to the frost position information and preset swing position relationship information.

[0066] The swing position relationship information refers to the position on the wiper heating swing arc that is heated and melted by the same heater. The operator obtains the swing position relationship information by associating the position coordinates covered by the same arc according to the actual situation of the wiper.

[0067] The frost-associated position information refers to the coordinate positions of the frost positions on the same arc. The processing terminal classifies the coordinate positions corresponding to the frost position information according to the association relationship between the coordinates corresponding to the swing position relationship information to obtain the frost-associated position information.

[0068] Step S303: obtaining ice thickness information at the location according to the frost-associated location information.

[0069] Among them, after the processing terminal obtains the frost-related position information, the position ice thickness information is detected according to the position corresponding to the independent frost-related position information, so as to provide data support for how the wiper can effectively melt and scrape off the frost involved in the arc.

[0070] The ice thickness information at the location refers to the ice thickness at the location corresponding to the frost associated location information. For specific detection methods, refer to Figure 4 steps.

[0071] Step S304: sorting the thicknesses corresponding to the ice thickness information at the locations and selecting the maximum value to determine the ice thickness information.

[0072] Among them, frost thickness information refers to the thickness of all frost involved in an arc. The processing terminal sorts the thicknesses corresponding to the position icing thickness information and selects the maximum value to obtain the thickness of the frost within the range of the arc. The maximum thickness enables the wiper to effectively scrape off all frost within the range of the arc.

[0073] Step S305: Correlate the frost-associated position information and the frost thickness information to determine frost parameter information.

[0074] Among them, the frost parameter information in this step is consistent with the frost parameter information in step S200, and the frost thickness information is obtained at the processing terminal. The position corresponding to the frost associated position information and the thickness corresponding to the frost thickness information are matched one by one and stored in the same data packet to form the frost parameter information.

[0075] Reference Figure 4 The step of obtaining the ice thickness information at the location according to the frost-related location information includes: Step S400: Acquire the external brightness information of the windshield.

[0076] The external brightness information refers to the brightness value outside the windshield, which is detected by a brightness sensor installed outside the light-transmitting glass and sent to a processing terminal.

[0077] Step S401: determining whether the external brightness information meets the preset light transmission brightness information requirement.

[0078] Among them, the light transmittance brightness information refers to the minimum brightness value that can be used for transmittance detection. The specific value is determined by the operator according to the actual situation. The requirement of the light transmittance brightness information refers to the brightness that is not less than that corresponding to the light transmittance brightness information, which is stored in the processing terminal by the operator.

[0079] The processing terminal determines whether the brightness value corresponding to the external brightness information is not less than the brightness corresponding to the light transmittance brightness information, thereby determining whether the light transmittance of the windshield can be detected.

[0080] Step S4011: If it meets the requirements, output the preset transmittance detection trigger information.

[0081] Among them, if the processing terminal determines that the brightness value corresponding to the external brightness information is not less than the brightness corresponding to the transmittance brightness information, it means that the external brightness is sufficient and the transmittance of the windshield can be detected. Therefore, the transmittance detection trigger information is output to provide a specific time for subsequent transmittance detection.

[0082] The transmittance detection trigger information refers to trigger data for starting transmittance detection, and is stored in the processing terminal by the operator.

[0083] Step S4012: If not, turn on the preset vehicle lights for fill light and output preset transmittance detection trigger information.

[0084] Among them, if the processing terminal determines that the brightness value corresponding to the external brightness information is less than the brightness corresponding to the transmittance brightness information, it means that the external brightness is low and transmittance detection cannot be performed. Therefore, the car lights are controlled to turn on for fill light, so that the brightness reaches the brightness corresponding to the transmittance brightness information, and then the transmittance detection trigger information is output to provide a specific time for subsequent transmittance detection.

[0085] The light transmittance detection trigger information in this step is consistent with the light transmittance detection trigger information in step S4011, and will not be described in detail here.

[0086] Step S402: Detect the transmittance of the position corresponding to the frost-associated position information according to the transmittance detection trigger information and the preset single detection area information to determine the transmittance detection information.

[0087] Among them, after the processing terminal receives the transmittance detection trigger information, the processing terminal controls the camera to capture the image at the position corresponding to the frost-related position information in a collection range corresponding to the single detection area information and identify the pixel value to obtain the transmittance brightness, and then calculates the quotient between the transmittance brightness and the external brightness to obtain the transmittance, thereby determining the transmittance detection information.

[0088] The single detection area information refers to the range of brightness collected at each frost position, and the specific value is determined by the operator according to the actual situation. The transmittance detection information refers to the transmittance of the frost-covered position on the windshield. The processing terminal controls the camera to capture the image corresponding to the frost-related position information in the collection range corresponding to the single detection area information and recognize the pixel value of the image to obtain the transmittance brightness, and then calculates the quotient between the transmittance brightness and the external brightness to obtain the transmittance. If the transmittance is lower, it means that the thickness of the frost is thicker.

[0089] Step S403: determining single detection thickness information according to the transmittance detection information and preset transmittance-thickness relationship information.

[0090] Among them, the transmittance-thickness relationship information refers to a database that stores the corresponding relationship between transmittance and frost thickness. The transmittance is inversely proportional to the frost thickness, that is, the higher the transmittance, the smaller the frost thickness. The operator covers the windshield with frost of different thicknesses, and then detects the quotient between the transmittance brightness and the light brightness after irradiating it with light to obtain the corresponding transmittance. Finally, the frost thickness and the transmittance are matched one by one and stored in the database to form the transmittance-thickness relationship information.

[0091] The single detection thickness information refers to the frost thickness obtained by a single detection in the position corresponding to the frost associated position information, and is obtained by matching and outputting the transmittance corresponding to the transmittance detection information into the database corresponding to the transmittance thickness relationship information by the processing terminal.

[0092] Step S404: Associating the single detection thickness information with the frost associated position information to generate position icing thickness information.

[0093] Among them, the position ice thickness information in this step is consistent with the position ice thickness information in step S303. After the processing terminal obtains the single detection thickness information, the thickness corresponding to the single detection thickness information is associated with the position where the thickness is detected in the corresponding position of the frost associated position information and stored in the same data packet to form the position ice thickness information.

[0094] Reference Figure 5 The step of controlling the wiper heating swing to remove frost on the windshield according to the wiper heating position information, the position heating temperature information and the defrosting trigger information includes: Step S500: Analyze the defrost trigger information to determine the wiper swing speed information.

[0095] The swing speed information refers to the swing speed of the wiper selected by the personnel, and is obtained by the processing terminal identifying the speed represented by the button pressed by the personnel in the defrost trigger information when receiving the defrost trigger information.

[0096] Step S501: Analyze the position heating temperature information, the swing speed information and the preset reference speed information to determine the actual position temperature information.

[0097] The reference speed information refers to the minimum speed of the wiper blade swing, and the specific value is determined by the operator according to the actual situation. The actual position temperature information refers to the temperature value actually required at different positions on the wiper blade. The processing terminal calls the swing speed information and the reference speed information, and then calculates the quotient between the two to obtain the gain coefficient, and then calculates the product between the gain coefficient and the temperature corresponding to the position heating temperature information to obtain the actual position temperature information.

[0098] Step S502: Controlling the wiper heating swing to remove frost on the windshield according to the wiper heating position information and the actual position temperature information.

[0099] Among them, after the processing terminal obtains the actual position temperature information, the processing terminal controls the heating wire at the position corresponding to the wiper heating position information on the wiper to heat according to the temperature value corresponding to the specific position in the actual position temperature information, and swings synchronously, so that the frost on the windshield is swept out of the windshield when it melts.

[0100] Reference Figure 6 The step of controlling the wiper to heat and swing to remove frost on the windshield according to the wiper heating position information and the actual position temperature information includes: Step S600: Controlling the heating swing of the wiper according to the heating position information of the wiper and the actual position temperature information, and obtaining the melting trigger information.

[0101] Among them, the processing terminal controls the heating wire at the position corresponding to the wiper heating position information on the wiper to heat it according to the temperature value corresponding to the specific position in the actual position temperature information, and swings synchronously so that the frost on the windshield is swept out of the windshield when it melts. The melting trigger information of the frost on the windshield is detected to provide data support for the subsequent control of the wiper.

[0102] The melting trigger information refers to the trigger data of frost melting into water detected by the wiper during the swinging process, which is detected by the humidity sensor installed on the wiper and sent to the processing terminal.

[0103] Step S601: acquiring detection angle information and detection position information based on melting trigger information.

[0104] The detection angle information refers to the swing angle of the wiper when the frost is detected to be melted, which is output by the motor that controls the wiper swing to the processing terminal. The detection position information refers to the position on the wiper where the frost is detected to be melted, and the processing terminal identifies the serial number of the humidity sensor that sends the melting trigger information, thereby determining the detection position information based on the corresponding relationship between the serial number and the position.

[0105] Step S602: Determine the start sequence number information according to the detected position information and the preset position sequence number relationship information.

[0106] Among them, the position serial number relationship information refers to a database that stores the corresponding relationship between the detection position and the start serial number. The operator matches the serial number of the water absorption device installed at different positions on the actual wiper with the position and stores it in the database to form the position serial number relationship information.

[0107] The start-up sequence number information refers to the sequence number of the water absorption device that needs to be started, which is obtained by matching and outputting the position corresponding to the detection position information into the database corresponding to the position sequence number relationship information by the processing terminal.

[0108] Step S603: starting a preset water absorption device according to the detection angle information and the start sequence number information to absorb the melted water to prevent the water from refreezing.

[0109] Among them, after the processing terminal obtains the startup sequence number information, when it detects that the swing angle of the wiper is the angle corresponding to the detection angle information, the water absorption device is controlled to absorb the melted water on the windshield, thereby preventing the melted water from remaining on the windshield and freezing again.

[0110] The water absorption device refers to a device used to absorb moisture on the windshield. The wiper is provided with a number of evenly distributed water absorption holes. The water absorption pump is connected to the water absorption holes through a water pipe, so as to absorb and discharge the moisture.

[0111] Reference Figure 7 Before obtaining the defrost trigger information of the wiper, an antifreeze step of the wiper is also included, and the specific steps include: Step S700: Acquire wiper status detection information.

[0112] Among them, the status detection information refers to the status data of the wiper, including the normal reset status and the upright status. When in the upright status, the wiper touches the upright button to send an electrical signal to the processing terminal to confirm the upright status. When not upright, no electrical signal is sent to the processing terminal to confirm the normal reset.

[0113] Step S701: Determine whether the status detection information meets the preset requirement of the upright status information.

[0114] The upright state information refers to the state of the wiper being in the upright state, and the requirement for the upright state information refers to the state being consistent with the state corresponding to the upright state information, both of which are stored in the processing terminal by the operator.

[0115] The processing terminal determines whether the state corresponding to the state detection information is consistent with the state corresponding to the upright state information, thereby determining whether the wiper needs to be kept warm to prevent the wiper from icing.

[0116] Step S7011: If it meets the conditions, continue to obtain the wiper status detection information for cyclic judgment.

[0117] Among them, if the processing terminal determines that the state corresponding to the state detection information is consistent with the state corresponding to the upright state information, it means that the wiper has been upright and there is no need to worry that the wiper will freeze on the windshield. Therefore, the state detection information of the wiper continues to be detected, thereby continuously monitoring the state of the wiper.

[0118] Step S7012: If not, obtain the ambient temperature information.

[0119] Among them, if the processing terminal determines that the state corresponding to the state detection information is inconsistent with the state corresponding to the upright state information, it indicates that the wiper is in a normal reset state. At this time, the wiper may be frozen on the windshield. Therefore, the ambient temperature information is detected to provide data support for the subsequent determination of whether the wiper needs to be insulated.

[0120] The ambient temperature information refers to the ambient temperature outside the windshield, which is detected by a temperature sensor and sent to a processing terminal.

[0121] Step S702: Determine constant temperature power information according to the ambient temperature information and preset temperature-power relationship information.

[0122] Among them, the temperature-power relationship information refers to a database that stores the correspondence between ambient temperature and constant temperature power. The ambient temperature is proportional to the constant temperature power. The specific correspondence is determined by the operator gradually increasing the heating power of the wiper under different ambient temperatures. When the heating power can ensure that the temperature of the wiper is always maintained slightly above zero degrees, the heating power and the ambient temperature at this time are stored in the database in correspondence to form temperature-power relationship information.

[0123] The constant temperature power information refers to the power value that keeps the temperature of the wiper slightly above zero degrees at all times, and is obtained by matching the output of the temperature corresponding to the ambient temperature information input into the database corresponding to the temperature-power relationship information by the processing terminal.

[0124] Step S703: Controlling the heating of the wipers according to the constant temperature power information to prevent the wipers from freezing.

[0125] Among them, after the processing terminal obtains the constant temperature power information, the processing terminal controls all the heating wires on the wiper to heat with the power corresponding to the constant temperature power information, thereby maintaining the temperature of the wiper at a constant temperature slightly above zero degrees to prevent the wiper from freezing on the windshield.
