Description

Technical Field

[0001] The present invention relates to the technical field of windshield wipers, and in particular to an automatic windshield wiper control method, device, equipment and storage medium. Background Art

[0002] With the rapid development of the automobile industry, vehicles are gradually becoming more automated and intelligent. Wiper control, as a device to ensure the safety of the driver's vision, is also becoming more automated and can adjust the wiper speed in real time according to the amount of rain.

[0003] The existing automatic wiper control strategy uses a rain sensor to sense the amount of rainfall, but does not take into account the influence of vehicle speed. As a result, the wipers may continue to wipe frequently while waiting at a traffic light, resulting in unnecessary energy waste. When the rainfall remains unchanged, the user controls the wiper working mode based on his or her own preferences and subjective judgment of the weather. Too fast a vehicle speed will directly affect the blocking effect of rain on the windshield, resulting in poor wiper effect under the original wiper mode, which cannot effectively ensure vehicle driving safety and results in a poor user experience. Summary of the invention

[0056] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0057] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0058] Figure 1 is a structural schematic diagram of an automatic wiper control system provided by an embodiment of the present invention; Figure 2 1 is a flow chart of an automatic wiper control method according to an embodiment of the present invention. This embodiment is applicable to the case where a vehicle uses a wiper to clean rain water from the front windshield during driving in rainy weather. The method can be executed by an automatic wiper control device, which can be implemented in the form of hardware and / or software. Figure 1As shown, the automatic wiper control system provided by the embodiment of the present invention includes: a vehicle speed sensor 1, a rain sensor 2, a processing unit 3, a wiper controller 4, a body control unit 5 and a wiper 6; the body control unit 5 is respectively connected to the vehicle speed sensor 1, the rain sensor 2, the processing unit 3 and the wiper controller 4, and the wiper 6 is connected to the wiper controller 4. Exemplarily, the vehicle speed sensor 1, the rain sensor 2, the processing unit 3, the wiper controller 4, the body control unit 5 and the wiper 6 can be connected based on a controller area network bus (Controller Area Network, CAN), a local interconnect network (Local Interconnect Network, LIN) or Ethernet.

[0059] like Figure 2 As shown, the automatic wiper control method based on the above structure includes the following steps:

[0060] S110: Obtain real-time vehicle speed and real-time rainfall value.

[0061] Specifically, the real-time speed of the moving vehicle is obtained by a speed sensor 1 installed on the wheel, and the speed sensor 1 may be a magnetic or Hall effect sensor; the real-time rainfall value is obtained by a rain sensor 2 installed on the front windshield of the vehicle, and the rain sensor 2 may be an infrared sensor. It should be noted that, under the premise of achieving the acquisition of the real-time speed and real-time rainfall value, the embodiment of the present invention does not specifically limit the types of detection devices for the speed and rainfall value.

[0062] Exemplarily, the vehicle speed sensor 1 is a magnetic sensor. When the wheel rotates, the magnet or electromagnetic coil on the wheel hub or brake disc passes through the vehicle speed sensor 1, thereby inducing a voltage signal in the coil. The frequency of these voltage signals is proportional to the rotation speed of the wheel or shaft. The real-time vehicle speed is determined by measuring the frequency of the voltage signal. The rain sensor 2 is an infrared sensor, including an infrared transmitter and an infrared receiver located on both sides of the windshield. When the windshield is dry, the infrared light beam emitted by the infrared transmitter is almost completely reflected back to the infrared receiver; however, once there are water droplets on the glass, the reflection path of the light beam will change, resulting in a decrease in the amount of light received by the receiver. By accurately measuring the change in the amount of light, the density of water droplets on the windshield is calculated, thereby detecting the real-time rainfall value on the windshield.

[0063] S120: Determine a rain compensation coefficient according to the real-time vehicle speed and wiper sensitivity level requirement.

[0064] Among them, the wiper sensitivity level requirement is selected by the driver based on his or her own preferences and current weather conditions. The higher the sensitivity level, the more sensitive the wiper is to rainfall.

[0065] Specifically, during the driving process of the vehicle, due to different vehicle speeds, the impact of raindrops on the windshield is different under the same rainfall conditions, thereby ensuring that the windshield is kept clean. The wiper sensitivity level determines the response rate of the wiper. Different wiper sensitivity levels are set to different wiper start-up speeds under the same rainfall conditions. After the rain sensor 2 collects the real-time rainfall value, it is sent to the processing unit 3. The processing unit 3 determines the rain compensation coefficient based on the real-time vehicle speed collected by the speed sensor 1 and the wiper sensitivity level requirement collected by the body control unit 5. The rain compensation coefficient is a parameter used to adjust the working state of the wiper. The vehicle can adaptively adjust the working state of the wiper through the rain compensation parameter, improve the flexibility of the wiper operation, better adapt to different driving environments and user-set conditions, ensure that the driver always has a clear field of vision, and help improve driving safety and comfort.

[0066] S130: Determine the rainfall level according to the real-time rainfall value.

[0067] Among them, the calibration process of rainfall level is described in a feasible implementation method:

[0068] The calibration process of rainfall level can be carried out in the following steps: 1) In the case of light rain, measure 40 rainfall changes α within 2 seconds 1 , α 2 ...α 40 The mean The α within these 2 seconds 1 , α 2 ...α 40 Respectively 1) Make a difference, take the square, sum and divide by 40 to get the mean of the sum of squares β, take the square root of β to get the root mean square value γ, γ reflects the fluctuation amplitude of the data deviating from the mean, collect α every 50ms, calculate the root mean square value γ of 40 data every 2 seconds, update it slidingly, and then sum the 40 root mean square values ​​γ to get the integral A of the fluctuation amplitude; 2) In the case of heavy rain, repeat the test steps of 1) above to get the integral B of the fluctuation amplitude; 3) Divide the integral A obtained under the test of light rain and the integral B obtained under the test of heavy rain into 10 rainfall levels according to 10 equal parts, and each level corresponds to a different integral value.

[0069] Specifically, within 2 seconds, the rain sensor 2 collects 41 real-time rainfall values ​​and sends the real-time rainfall values ​​to the processing unit 3. The processing unit 3 obtains the average value of 40 rainfall changes x according to the 41 real-time rainfall values. Compare the x in these 2 seconds with Make a difference and take the square, then sum and divide by 40 to get the mean y of the sum of squares, take the square root of y to get the root mean square value z, obtain x every 50ms, calculate the root mean square value z of 40 data every 2 seconds, update it slidingly, and then sum the 40 root mean square values ​​z to get the integral C of the fluctuation amplitude. The integral C calculated by the processing unit 3 is queried according to the corresponding relationship between the integral size and the rainfall level to get the rainfall level.

[0070] S140: Determine a real-time compensated rainfall value according to the rainfall level and the rainfall compensation coefficient.

[0071] Specifically, the processing unit 3 may multiply the obtained rainfall level by the rainfall supplement coefficient to determine the real-time compensation rainfall value.

[0072] S150. Determine a continuous wiping sub-mode of the wiper in the continuous wiping mode according to the real-time compensated rainfall value, wherein different continuous wiping sub-modes have different wiping speeds and / or wiping frequencies.

[0073] Specifically, the processing unit 3 determines the continuous wiping mode of the wiper based on the real-time compensated rainfall value, generates a corresponding control instruction and sends it to the body control unit 5, the body control unit 5 forwards the control instruction to the wiper controller 4, and the wiper controller 4 drives the wiper 6 to work in the continuous wiping mode according to the control instruction. The wiping speed and / or wiping frequency in different continuous wiping modes are different to adapt to the wiping needs in different situations, ensuring that the driver always has a clear field of vision and improving driving safety.

[0074] Exemplarily, the continuous scraping mode may include: a first continuous scraping sub-mode, a second continuous scraping sub-mode and a third continuous scraping sub-mode, the scraping speed of the first continuous scraping sub-mode is 0.3m / s, the scraping frequency is 20 times / minute, the scraping speed of the second continuous scraping sub-mode is 0.6m / s, the scraping frequency is 40 times / minute, and the scraping speed of the third continuous scraping sub-mode is 0.9m / s, and the scraping frequency is 60 times / minute. It should be noted that the above only exemplarily shows the number of continuous scraping sub-modes and the scraping speed and scraping frequency under each continuous scraping sub-mode, and the specific setting of the continuous scraping sub-mode in the embodiment of the present invention can be designed according to actual needs, and the embodiment of the present invention does not specifically limit this.

[0075] This embodiment determines the rain compensation coefficient by obtaining the real-time vehicle speed and wiper sensitivity level requirements, and determines the rain level based on the real-time rain value, and then determines the real-time compensated rain value according to the rain level and the rain compensation coefficient. The working mode of the wiper is adjusted by the real-time compensated rain value to achieve automatic adjustment of the wiper working state according to actual conditions, avoid unnecessary energy waste, and provide the driver with a safer and more convenient driving experience.

[0076] Based on the above embodiments, Figure 3 is a flow chart of another automatic wiper control method provided according to an embodiment of the present invention. Figure 3 The control method shown in FIG. 1 illustrates how to determine the continuous scraping brush mode. Figure 3 As shown, the automatic wiper control method includes the following steps:

[0077] S210: Obtain real-time vehicle speed and real-time rainfall value.

[0078] S220: Determine a rain compensation coefficient according to the real-time vehicle speed and wiper sensitivity level requirement.

[0079] S230: Determine the rainfall level according to the real-time rainfall value.

[0080] S240: Determine a real-time compensated rainfall value according to the rainfall level and the rainfall compensation coefficient.

[0081] S250, presetting different compensation rainfall thresholds corresponding to the continuous scraping brush modes.

[0082] The compensation rainfall threshold includes an i-th threshold and an (i+1)-th threshold, and the (i+1)-th threshold is greater than the i-th threshold; wherein i is a positive integer.

[0083] Specifically, the continuous wiping sub-mode is that after the processing unit 3 issues a control instruction, the body control unit 5 forwards the control instruction to the wiper controller 4, and then the wiper controller 4 drives the wiper to wipe continuously at a specific wiping speed and wiping frequency according to the control instruction. Different compensation rain thresholds are set in advance for different continuous wiping sub-modes, the preset compensation rain threshold of the i-th continuous wiping sub-mode is the i-th threshold, the compensation rain threshold of the (i+1)th continuous wiping sub-mode is the (i+1)th threshold, the (i+1)th threshold is greater than the i-th threshold, the wiping speed and / or wiping frequency of the i-th continuous wiping sub-mode is greater than the wiping speed and / or wiping frequency of the (i+1)th continuous wiping sub-mode, that is, the greater the wiping speed and / or wiping frequency, the greater the compensation rain threshold for entering the continuous wiping sub-mode.

[0084] Exemplarily, the continuous scraping mode includes a first continuous scraping sub-mode and a second continuous scraping sub-mode, the scraping speed of the first continuous scraping sub-mode is 0.3 m / s, the scraping frequency is 20 times / minute, the preset first threshold is 1, the scraping speed of the second continuous scraping sub-mode is 0.6 m / s, the scraping frequency is 40 times / minute, and the preset second threshold is 2. It should be noted that the above only exemplarily shows a preset situation of the continuous scraping sub-mode, and is not a specific limitation of the embodiment of the present invention.

[0085] S260: When the real-time compensated rainfall value is greater than the ith threshold value and less than the (i+1)th threshold value, determine that the wiping mode of the wiper is a continuous wiping sub-mode corresponding to the ith threshold value.

[0086] Specifically, when the processing unit 3 obtains the real-time compensated rainfall value, the real-time compensated rainfall value is compared with each threshold value. When the real-time compensated rainfall value is between the i-th threshold value and the (i+1)-th threshold value, the processing unit 3 generates a control instruction for the continuous wiping sub-mode corresponding to the i-th threshold value. After the control instruction is forwarded to the wiper controller 4 by the body control unit 5, the wiper controller 4 drives the wiper to wipe in the continuous wiping sub-mode corresponding to the i-th threshold value.

[0087] For example, the first continuous wiping mode, the second continuous wiping mode and the third continuous wiping mode, the wiping speed of the first continuous wiping mode is 0.3m / s, the wiping frequency is 20 times / minute, and the preset first threshold is 1; the wiping speed of the second continuous wiping mode is 0.6m / s, the wiping frequency is 40 times / minute, and the preset second threshold is 2; the wiping speed of the third continuous wiping mode is 0.9m / s, the wiping frequency is 60 times / minute, and the preset third threshold is 3. If the real-time compensation rainfall obtained by the processing unit 3 is 2.5, the real-time compensation rainfall is between the second threshold and the third threshold, and the wiper works in the second continuous wiping mode corresponding to the second threshold; if the real-time compensation rainfall obtained by the processing unit 3 is 1.7, the real-time compensation rainfall is between the first threshold and the second threshold, and the wiper works in the first continuous wiping mode corresponding to the first threshold. It should be noted that the above only exemplarily shows the judgment process of the wiper determining the continuous wiping mode, and is not a specific limitation of the embodiment of the present invention.

[0088] This embodiment presets different compensation rainfall thresholds corresponding to continuous wiping modes, compares the real-time compensation rainfall value with each threshold, determines between which two threshold ranges the real-time compensation rainfall value is located, and then controls the wiper to operate in the continuous wiping mode corresponding to the lower threshold of the threshold range. Under the premise of ensuring a clear field of vision for the driver, the accuracy and flexibility of controlling the wiper operating mode are improved.

[0089] Based on the above embodiments, Figure 4 is a flow chart of another automatic wiper control method provided according to an embodiment of the present invention. Figure 4 The control method shown in FIG. 1 illustrates how to determine the rainfall compensation coefficient. Figure 4 As shown, the automatic wiper control method includes the following steps:

[0090] S310: Obtain real-time vehicle speed and real-time rainfall value.

[0091] S320: Determine the speed range within which the real-time vehicle speed lies.

[0092] Specifically, the vehicle speed sensor 1 sends the detected real-time vehicle speed to the body control unit 5, and the body control unit 5 forwards the real-time vehicle speed to the processing unit 3, and then the processing unit 3 determines the vehicle speed interval range that the real-time vehicle speed is in. Exemplarily, the vehicle speed interval range can be divided into greater than or equal to 0km / h and less than or equal to 10km / h, greater than 10km / h and less than or equal to 80km / h, and greater than 80km / h.

[0093] S330: Determine a rain compensation coefficient according to a vehicle speed range and a wiper sensitivity level requirement.

[0094] Among them, within the same vehicle speed range, the wiper sensitivity level requirement is positively correlated with the rain compensation coefficient; within the same wiper sensitivity level requirement, the vehicle speed value within the vehicle speed range is positively correlated with the rain compensation coefficient.

[0095] Specifically, the processing unit 3 can perform a table lookup operation in the speed range-sensitivity level-rainfall compensation coefficient table according to the speed range and the wiper sensitivity level requirement, and determine the rainfall compensation coefficient according to the table lookup result. In the speed range-sensitivity level-rainfall compensation coefficient table, when it is determined that the real-time vehicle speed is within a certain speed range, the greater the wiper sensitivity level requirement set by the driver, the greater the rainfall compensation coefficient determined by the processing unit 3; when the wiper sensitivity level requirement set by the driver remains unchanged, the greater the speed value of the speed range in which the real-time vehicle speed is located, the greater the rainfall compensation coefficient determined by the processing unit 3.

[0096] For example, the vehicle speed range-sensitivity level-rainfall compensation coefficient table is shown in the following table:

[0097]

[0098] Among them, within the same vehicle speed range, the rain compensation coefficients A1-A4 gradually increase, B1-B4 gradually increase, and C1-C4 gradually increase; at the same sensitivity level, the rain compensation coefficients A1-C1 gradually increase, A2-C2 gradually increase, A3-C3 gradually increase, and A4-C4 gradually increase. The rain compensation coefficients A1-A4 can be a value less than 1, that is, when the real-time vehicle speed is 0-10km / h, the demand for wipers is not high during slow driving, and the real-time rain value can be reduced and corrected by the rain compensation coefficient to reduce the frequency and speed of continuous wipers and avoid unnecessary energy waste; the rain compensation coefficients B1-B4 and C1-C4 can be values ​​greater than 1, that is, the vehicle speed is accelerated and / or the sensitivity level requirement is set larger, which means that the demand for wipers during driving becomes greater, and the real-time rain can be amplified and corrected by the rain compensation coefficient to increase the frequency and speed of continuous wipers and ensure the driver's clear vision. It should be noted that the above table of vehicle speed range-sensitivity level-rainfall compensation coefficient is only shown by way of example. The table can be calibrated and produced according to the results of previous tests. This embodiment does not impose any specific limitation on the specific data in the table of vehicle speed range-sensitivity level-rainfall compensation coefficient.

[0099] S340: Determine the rainfall level according to the real-time rainfall value.

[0100] S350: Determine a real-time compensated rainfall value according to the rainfall level and the rainfall compensation coefficient.

[0101] S360: Determine a continuous wiping sub-mode of the wiper in the continuous wiping mode according to the real-time compensated rainfall value, wherein the wiping speed and / or wiping frequency are different in different continuous wiping modes.

[0102] This embodiment determines the speed range in which the real-time vehicle speed is located, and determines the rainfall compensation coefficient according to the speed range and the wiper sensitivity level requirement to correct the real-time rainfall value. It no longer relies solely on the real-time rainfall value as a single factor to determine the wiper wiping mode, but instead comprehensively considers the three factors of real-time rainfall value, real-time vehicle speed and sensitivity level requirement, so that the wiper operation is more in line with actual needs, improves the wiper wiping effect, ensures driving safety, and also avoids unnecessary energy waste of the wiper.

[0103] Based on the above embodiments, Figure 5 is a flow chart of another automatic wiper control method provided according to an embodiment of the present invention. Figure 5 The above automatic wiper control method is further described. Figure 5 As shown, the automatic wiper control method includes the following steps:

[0104] S410: Preset the corresponding relationship between the real-time vehicle speed, the wiper sensitivity level requirement and the rain compensation coefficient.

[0105] S420, preset the corresponding relationship between rainfall value and rainfall level.

[0106] S430: Obtain real-time vehicle speed and real-time rainfall value.

[0107] S440: Determine a rain compensation coefficient according to the real-time vehicle speed and wiper sensitivity level requirement.

[0108] S450: Determine the rainfall level according to the real-time rainfall value.

[0109] S460: Determine a real-time compensation rainfall value according to the rainfall level and the rainfall compensation coefficient.

[0110] S470. Determine a continuous wiping sub-mode of the wiper in the continuous wiping mode according to the real-time compensated rainfall value, wherein the wiping speed and / or wiping frequency are different in different continuous wiping modes.

[0111] Specifically, the correspondence between the real-time vehicle speed, the wiper sensitivity level requirement and the rain compensation coefficient, as well as the correspondence between the rainfall value and the rainfall level are calibrated experimentally, and the two correspondences are stored in the processing unit 3. The processing unit 3 can query the rain compensation coefficient at this time according to the current real-time vehicle speed and the wiper sensitivity level requirement set by the current user, and query the current rainfall level according to the real-time rainfall value collected by the current rain sensor 2, so as to correct the continuous wiping mode of the wiper, so that the wiper operation is more in line with actual needs.

[0112] For example, the corresponding relationship between the preset real-time vehicle speed, wiper sensitivity level requirement and rain compensation coefficient can be: when the vehicle speed is less than 20km / h, the wiper sensitivity level requirement set by the driver is 1, and the corresponding rain compensation coefficient is 0.5; when the vehicle speed is between 20-40km / h, the wiper sensitivity level requirement set by the driver is 2, and the corresponding rain compensation coefficient is 1; when the vehicle speed is between 40-60km / h, the wiper sensitivity level requirement set by the driver is 3, and the rain compensation coefficient is 1.5. The corresponding relationship between the preset rainfall value and the rainfall level can be: when the rainfall value is less than 10mm, the corresponding rainfall level is 1; when the rainfall value is between 10mm-25mm, the corresponding rainfall level is 2; when the rainfall value is between 25mm-50mm, the corresponding rainfall level is 3.

[0113] It should be noted that Figure 5Only an exemplary sequence of the automatic wiper control method is shown. In fact, step S410 can be before or after step S420, or before or after step S430, as long as step S410 is before step S440; similarly, step S420 can be before or after step S410, before or after step S430, or before or after step S440. That is, before ensuring that the rain compensation coefficient is determined according to the real-time vehicle speed and the wiper sensitivity level requirement, the corresponding relationship between the real-time vehicle speed, the wiper sensitivity level requirement and the rain compensation coefficient is preset, and before ensuring that the rain level is determined according to the real-time rain value, the corresponding relationship between the rain value and the rain level is preset, the position of step S410 and step S420 in the automatic wiper control method process is not specifically limited.

[0114] For example, Figure 6 is a flow chart of another automatic wiper control method provided according to an embodiment of the present invention. Figure 6 As shown, the automatic wiper control method also includes the following steps:

[0115] S430: Obtain real-time vehicle speed and real-time rainfall value.

[0116] S410: Preset the corresponding relationship between the real-time vehicle speed, the wiper sensitivity level requirement and the rain compensation coefficient.

[0117] S440: Determine a rain compensation coefficient according to the real-time vehicle speed and wiper sensitivity level requirement.

[0118] S420, preset the corresponding relationship between rainfall value and rainfall level.

[0119] S450: Determine the rainfall level according to the real-time rainfall value.

[0120] S460: Determine a real-time compensation rainfall value according to the rainfall level and the rainfall compensation coefficient.

[0121] S470. Determine a continuous wiping sub-mode of the wiper in the continuous wiping mode according to the real-time compensated rainfall value, wherein the wiping speed and / or wiping frequency are different in different continuous wiping modes.

[0122] Based on the above embodiments, Figure 7 is a flow chart of another automatic wiper control method provided according to an embodiment of the present invention. Figure 7 The above automatic wiper control method is further described. Figure 7 As shown, the automatic wiper control method includes the following steps:

[0123] S510: In the current detection phase, when the real-time rainfall value is greater than the wiper threshold for the first time, the wiper is controlled to perform the first wipe.

[0124] Specifically, during vehicle driving, when the rain sensor 2 detects that the real-time rainfall value on the windshield is greater than the wiping threshold for the first time, the processing unit 3 generates and sends a control signal for wiping once, and the body control unit 5 receives and forwards the control signal to the wiper controller 4. The wiper controller 4 controls the wiper 6 to perform the first wiping action to clear the rain on the windshield.

[0125] S520: When the real-time rainfall value is greater than the wiper threshold for the second time, control the wiper to perform a second wipe.

[0126] Specifically, after the first wipe, the vehicle is still in the driving process. When the rain sensor 2 detects that the real-time rainfall value on the windshield is greater than the wiper threshold for the second time, the processing unit 3 generates and sends a control signal for wipe again. The body control unit 5 receives and forwards the control signal to the wiper controller 4. The wiper controller 4 controls the wiper 6 to perform a second wipe to clear the rain on the windshield.

[0127] S530: If the time interval between the second wiping and the first wiping is less than the first preset time interval t1, the wiper is controlled to enter the supplementary wiping mode, and the wiper is controlled to wiping according to the supplementary wiping mode.

[0128] Specifically, when the wiper controller 4 controls the wiper 6 to perform a single wiping, it feeds back the time of the single wiping to the body control unit 5, and the body control unit 5 forwards the time of the single wiping to the processing unit 3, and the processing unit 3 calculates the time interval between two single wiping and compares the time interval with the first preset time interval t1. If the time interval between the two single wiping is less than the first preset time interval t1, it means that the rain is getting heavier, and the real-time rainfall value detected in a shorter time reaches the wiping threshold again in a shorter time, then the processing unit 3 controls the wiper 6 to enter the supplementary wiping mode, and the wiper 6 performs wiping in the supplementary wiping mode.

[0129] This embodiment presets a wiping threshold and a first preset time interval. When the real-time rainfall value is detected to be greater than the wiping threshold, a single wiping is performed. When the time interval between two single wiping is greater than the first preset time interval, the wiper is controlled to enter a supplementary wiping mode, thereby improving the flexibility of the wiper operation and making the wiper operation more in line with actual needs.

[0130] Based on the above embodiments, Figure 8 is a flow chart of another automatic wiper control method provided according to an embodiment of the present invention. Figure 8 The following describes how to control the wipers to wipe in the supplementary wiping mode. Figure 8 As shown, the automatic wiper control method includes the following steps:

[0131] S610: In the current detection phase, when the real-time rainfall value is greater than the wiper threshold for the first time, control the wiper to perform the first wipe.

[0132] S620: When the real-time rainfall value is greater than the wiper threshold for the second time, control the wiper to perform a second wipe.

[0133] S630: If the time interval between the second wiping and the first wiping is less than the first preset time interval t1, the wiper is controlled to enter the supplementary wiping mode, and the wiper is controlled to wiping according to the supplementary wiping mode.

[0134] S640: When the real-time rainfall value is greater than the threshold value for starting to blow for the third time, the real-time time is recorded.

[0135] Specifically, during vehicle driving, after the wiper 6 performs two wiping actions, when the rain sensor 2 detects that the real-time rainfall value on the windshield is greater than the wiping threshold for the third time, the real-time time at this time is recorded.

[0136] S650: If the time interval between the real time and the second wiping time is less than the second preset time interval t2, control the wiper to wipe based on the second wiping time when the second preset time interval t2 is reached.

[0137] The second preset time interval t2 is smaller than the first preset time interval t1.

[0138] Specifically, based on the second wiping time of the wiper 6 fed back by the wiper controller 4 to the processing unit 3, the processing unit 3 calculates the time interval between the real-time time when the real-time rainfall value is greater than the wiping start threshold for the third time and the second wiping time; if the time interval between the real-time time and the second wiping time is less than the second preset time interval t2, indicating that the time interval between the time when a single wiping is required for the third time and the second wiping time is too small, the wiper 6 is controlled to perform a third wiping after the second preset time interval t2 based on the time of the second wiping.

[0139] S660: If the time interval between the real time and the second wiping time is greater than or equal to the second preset time interval t2 and less than the third preset time interval t3, control the wipers to wipe immediately.

[0140] The third preset time interval t3 is greater than the first preset time interval t1.

[0141] Specifically, based on the second wiping time of the wiper 6 fed back by the wiper controller 4 to the processing unit 3, the processing unit 3 calculates the time interval between the real-time time when the real-time rainfall value is greater than the wiping start threshold for the third time and the second wiping time; if the time interval between the real-time time and the second wiping time is greater than or equal to the second preset time interval t2 and less than the third preset time interval t3, it means that the time interval between the time when a single wiping is required for the third time and the second wiping time is moderate and close to the time interval between the first wiping and the second wiping, and the wiper 6 can be controlled to perform the third wiping immediately.

[0142] S670: If, based on the time of the second wipe, it is detected that the real-time rainfall value is less than the wiper threshold value when the third preset time interval t3 is reached, control the wiper to wipe when the third preset time interval t3 is reached.

[0143] Specifically, based on the second wiping time of the wiper 6 fed back by the wiper controller 4 to the processing unit 3, if the real-time rainfall value on the windshield is not detected to be greater than the wiping threshold within the third preset time interval t3 after the second wiping time, the wiper 6 is controlled to perform a third wiping when the third preset time interval t3 is reached.

[0144] For example, assuming that the second wiping time is 3s, the first preset time interval t1 is 2s, the second preset time interval t2 is 1.5s, and the third preset time interval t2 is 2.5s. If the real-time time when the detected real-time rainfall value is greater than the wiping threshold for the third time is 4s, the time interval between the real-time time and the second wiping time is 1s, which is less than the second preset time interval, and the wiper is controlled to wipe at 4.5s; if the real-time time when the detected real-time rainfall value is greater than the wiping threshold for the third time is 5.1s, the time interval between the real-time time and the second wiping time is 2.1s, which is greater than the second preset time interval and less than the third preset time interval, and the wiper is controlled to wipe at 5.1s; if the rain sensor 2 does not detect that the real-time rainfall value is greater than the wiping threshold in the time period from 3s to 5.5s, and the real-time rainfall value detected at 5.5s is less than the wiping threshold, the wiper is controlled to wipe at 5.5s.

[0145] Optionally, the automatic wiper control method further includes:

[0146] If the real-time rainfall is detected to be less than the wiping threshold value for a preset number of consecutive times when the third preset time interval t3 is reached based on the time of the last wiping, the re-wiping mode is exited; when the real-time rainfall value is greater than the wiping threshold value, the wiper is controlled to perform a single wiping.

[0147] The number of consecutive preset times can be three, which is not specifically limited in this embodiment.

[0148] Specifically, when the continuous preset number of times can be three times, based on the time of the last scraping, if the real-time rainfall value of the windshield detected by the rain sensor 2 within the third preset time interval t3 for three consecutive times is not greater than the scraping threshold, then scraping is performed once every third preset time interval t3. After completing a total of three scraping actions, the wiper 6 exits the supplementary scraping mode and enters the control method where the wiper performs a single scraping when the real-time rainfall value is greater than the scraping threshold.

[0149] This embodiment controls the wiper to perform a single wipe in the supplementary wipe mode. Compared with the prior art, the single wipe control method no longer relies solely on the single factor of whether the real-time rainfall value is greater than the wipe threshold, but comprehensively considers whether the time interval between two single wipes is too large, thereby avoiding the interval between two wipes being too long or too short, ensuring the continuity of the wiper, and improving the driver's driving experience. In the supplementary wipe mode, when the real-time rainfall value is not detected to be greater than the wipe threshold within a certain interval, the wipe strategy of the preset number of times is increased to prevent the front windshield from raining but the sensor does not detect rain and does not perform wipe, which affects the driver's line of sight, providing a safer driving experience for the driver.
