[0056] In order to enable persons skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative work should fall within the protection scope of the present application.

[0057] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily mean a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but can 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 according to an embodiment of the present application; Figure 2 is an automatic wiper control method flow chart provided according to an embodiment of the present application. The embodiment can be applicable to the case that a vehicle uses a wiper to clean the rainwater on the front windshield during driving in rainy days. The method can be executed by an automatic wiper control device, which can be realized in the form of hardware and / or software. As shown in the figure, Figure 1As shown, the automatic wiper control system provided by the embodiment of the present application comprises a vehicle speed sensor 1, a rain amount 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 connected with the vehicle speed sensor 1, the rain amount sensor 2, the processing unit 3 and the wiper controller 4 respectively, and the wiper 6 is connected with the wiper controller 4. Exemplarily, the vehicle speed sensor 1, the rain amount 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 (CAN) bus, a Local Interconnect Network (LIN) or an Ethernet.

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

[0060] S110, acquiring a real-time vehicle speed and a real-time rain amount value.

[0061] Specifically, the real-time vehicle speed of the running vehicle is acquired by the vehicle speed sensor 1 installed on the wheel, which can be a magnetic or Hall effect sensor; the real-time rain amount value is acquired by the rain amount sensor 2 installed on the front windshield of the vehicle, which can be an infrared sensor. It should be noted that, under the premise of realizing the acquisition of the real-time vehicle speed and the real-time rain amount value, the type of the detection device for the vehicle speed and the rain amount value is not limited in the embodiment of the present application.

[0062] Exemplarily, the vehicle speed sensor 1 is a magnetic sensor, when the wheel rotates, the magnet or the electromagnetic coil on the hub or the brake disc passes through the vehicle speed sensor 1, thereby inducing a voltage signal in the coil, the frequency of the voltage signal is proportional to the rotation speed of the wheel or the shaft, and the real-time vehicle speed is determined by measuring the frequency of the voltage signal. The rain amount sensor 2 is an infrared sensor, which comprises an infrared emitter and an infrared receiver located on both sides of the windshield respectively, when the windshield is dry, the infrared light beam emitted by the infrared emitter is almost completely reflected back to the infrared receiver; however, as soon as there is a water droplet 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, and by accurately measuring the change in the amount of light, the water droplet density on the windshield is calculated, thereby detecting the real-time rain amount value on the windshield.

[0063] S120, determining a rain amount compensation coefficient according to the real-time vehicle speed and the sensitivity level requirement of the wiper.

[0064] The sensitivity level requirement of the wiper is selected by the driver according to his own preference and the current weather condition, and the higher the sensitivity level is, the more sensitive the response of the wiper to the rain amount is.

[0065] Specifically, during vehicle operation, varying vehicle speeds result in different levels of impact from raindrops on the windshield under the same rainfall conditions, thus requiring different wiper actions to keep the windshield clean. The wiper sensitivity level determines the wiper response rate; different sensitivity levels result in different wiper activation speeds under the same rainfall conditions. After the rain sensor 2 collects real-time rainfall data, it sends it to the processing unit 3. The processing unit 3 combines the real-time vehicle speed collected by the vehicle speed sensor 1 and the wiper sensitivity level requirements collected by the body control unit 5 to determine the rain compensation coefficient. The rain compensation coefficient is a parameter used to adjust the wiper operation. The vehicle can adaptively adjust the wiper operation through the rain compensation parameter, improving the wiper's flexibility and better adapting to different driving environments and user-set conditions, ensuring the driver always has a clear view and contributing to improved driving safety and comfort.

[0066] S130. Determine the rainfall level based on the real-time rainfall value.

[0067] The calibration process for rainfall levels is illustrated using one feasible implementation method:

[0068] The calibration process for rainfall levels can involve the following steps: 1) Under light rain conditions, measure 40 rainfall changes α1, α2...α within 2 seconds. 40 mean Within these 2 seconds, α1, α2...α 40 respectively with 1) Subtract the values, square them, sum them, 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. α is collected every 50ms. The root mean square value γ of 40 data points within 2 seconds is calculated. The data is updated by sliding. The 40 root mean square values ​​γ are summed to get the integral of the fluctuation amplitude, A. 2) Under heavy rain conditions, repeat the test steps in 1) above to get the integral of the fluctuation amplitude, B. 3) Divide the integral A obtained under light rain conditions and the integral B obtained under heavy rain conditions into 10 equal parts to form 10 rainfall levels. 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 them to the processing unit 3. The processing unit 3 then calculates the average of 40 rainfall variation values ​​x based on these 41 real-time rainfall values. Compare x within these 2 seconds with The difference is subtracted, and the square is summed and divided by 40 to obtain the mean value y of the square sum, and the square root of y is obtained to obtain the root mean square value z. x is obtained every 50 ms, the root mean square value z of 40 data in every 2 seconds is calculated, and the root mean square value z is summed to obtain the integral C of the fluctuation amplitude. The integral C calculated by the processing unit 3 is obtained according to the corresponding relationship between the integral size and the rain grade.

[0070] S140, determining the real-time compensation rain value according to the rain grade and the rain compensation coefficient.

[0071] Specifically, the processing unit 3 can multiply the obtained rain grade and the rain compensation coefficient to determine the real-time compensation rain value.

[0072] S150, determining the continuous wiping sub-mode of the wiper in the continuous wiping mode according to the real-time compensation rain value, and the wiping speed and / or wiping frequency are different in different continuous wiping sub-modes.

[0073] Specifically, the processing unit 3 determines the continuous wiping sub-mode of the wiper based on the real-time compensation rain value, generates corresponding control instructions and sends them to the vehicle body control unit 5, the vehicle body control unit 5 sends the control instructions to the wiper controller 4, and the wiper controller 4 drives the wiper 6 to work in the wiping mode of the continuous wiping sub-mode according to the control instructions. The wiping speed and / or wiping frequency are different in different continuous wiping sub-modes to adapt to the wiping requirements in different situations and ensure that the driver always has a clear view, improving the safety of driving.

[0074] For example, the continuous wiping mode can include a first continuous wiping sub-mode, a second continuous wiping sub-mode and a third continuous wiping sub-mode. The wiping speed of the first continuous wiping sub-mode is 0.3 m / s, and the wiping frequency is 20 times per minute. The wiping speed of the second continuous wiping sub-mode is 0.6 m / s, and the wiping frequency is 40 times per minute. The wiping speed of the third continuous wiping sub-mode is 0.9 m / s, and the wiping frequency is 60 times per minute. It should be noted that the above only exemplarily shows the number of continuous wiping sub-modes and the wiping speed and wiping frequency in each continuous wiping sub-mode, and the specific setting of the continuous wiping sub-mode in the embodiment of the application can be designed according to actual needs, and the embodiment of the application does not make specific limitations.

[0075] The embodiment determines the rain compensation coefficient by obtaining the real-time vehicle speed and the wiper sensitivity grade requirement, determines the rain grade based on the real-time rain value, and then determines the real-time compensation rain value according to the rain grade and the rain compensation coefficient. The working mode of the wiper is adjusted by the real-time compensation rain value to automatically adjust the working state of the wiper according to the actual situation, avoid unnecessary energy waste, and also provide a more safe and convenient driving experience for the driver.

[0076] On the basis of the above embodiments, Figure 3 is another automatic wiper control method flow chart provided according to an embodiment of the application, Figure 3 The control method shown illustrates how to determine the continuous wiper sub-mode. As shown in the figure, Figure 3 The automatic wiper control method comprises the following steps:

[0077] S210, acquiring real-time vehicle speed and real-time rainfall value.

[0078] S220, determining rainfall compensation coefficient according to real-time vehicle speed and wiper sensitivity level requirement.

[0079] S230, determining rainfall level according to real-time rainfall value.

[0080] S240, determining real-time compensation rainfall value according to rainfall level and rainfall compensation coefficient.

[0081] S250, presetting compensation rainfall threshold values corresponding to different continuous wiper sub-modes.

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

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

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

[0085] S260, when the real-time compensation rainfall value is greater than the i-th threshold value and less than the (i+1)-th threshold value, determining that the wiping mode of the wiper is the continuous wiping sub-mode corresponding to the i-th threshold value.

[0086] Specifically, when the processing unit 3 obtains the real-time compensation rainfall value, the real-time compensation rainfall value is compared with each threshold value, when the real-time compensation rainfall value is between the i-th threshold value and the (i+1)-th threshold value, the processing unit 3 generates the control instruction of the continuous wiping sub-mode corresponding to the i-th threshold value, and the control instruction is forwarded to the wiper controller 4 by the vehicle body control unit 5, and then 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 sub-mode, the second continuous wiping sub-mode and the third continuous wiping sub-mode, the wiping speed of the first continuous wiping sub-mode is 0.3 m / s, the wiping frequency is 20 times per minute, and the preset first threshold value is 1; the wiping speed of the second continuous wiping sub-mode is 0.6 m / s, the wiping frequency is 40 times per minute, and the preset second threshold value is 2; the wiping speed of the third continuous wiping sub-mode is 0.9 m / s, the wiping frequency is 60 times per minute, and the preset third threshold value is 3. If the real-time compensation rainfall value obtained by the processing unit 3 is 2.5, the real-time compensation rainfall value is between the second threshold value and the third threshold value, and the wiper works in the second continuous wiping sub-mode corresponding to the second threshold value; if the real-time compensation rainfall value obtained by the processing unit 3 is 1.7, the real-time compensation rainfall value is between the first threshold value and the second threshold value, and the wiper works in the first continuous wiping sub-mode corresponding to the first threshold value. It should be noted that the above is only an example of the determination process of the wiper to determine the continuous wiping sub-mode, and is not a specific limitation of the embodiment of the present application.

[0088] The embodiment predefines different compensation rainfall threshold values corresponding to different continuous wiping sub-modes, compares the real-time compensation rainfall value with each threshold value, determines which two threshold value ranges the real-time compensation rainfall value is between, and then controls the wiper to work in the continuous wiping sub-mode corresponding to the lower threshold value of the threshold value range, thereby improving the accuracy and flexibility of controlling the working mode of the wiper under the premise of ensuring the clear vision of the driver.

[0089] On the basis of the above embodiment, Figure 4 is another automatic wiper control method flowchart provided by the embodiment of the present application, Figure 4 The control method shown in the figure illustrates how to determine the rainfall compensation coefficient. As Figure 4 The automatic wiper control method comprises the following steps:

[0090] S310, obtaining a real-time vehicle speed and a real-time rainfall value.

[0091] S320, determining a vehicle speed interval range in which the real-time vehicle speed is located.

[0092] Specifically, the vehicle speed sensor 1 sends the detected real-time vehicle speed to the body control unit 5, 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 in which the real-time vehicle speed is located at this time. For example, the vehicle speed interval range can be divided into greater than or equal to 0 km / h and less than or equal to 10 km / h, greater than 10 km / h and less than or equal to 80 km / h, and greater than 80 km / h.

[0093] S330, determining the rainfall compensation coefficient according to the vehicle speed interval range and the wiper sensitivity level requirement.

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

[0095] Specifically, the processing unit 3 can perform a table lookup operation in the vehicle speed interval range-sensitivity level-rainfall compensation coefficient table according to the vehicle speed interval range and the wiper sensitivity level requirement, and determine the rainfall compensation coefficient according to the table lookup result. In the vehicle speed interval range-sensitivity level-rainfall compensation coefficient table, when it is determined that the real-time vehicle speed is in a certain vehicle speed interval 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 vehicle speed value of the vehicle speed interval 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 interval range-sensitivity level-rainfall compensation coefficient table is shown in the following table:

[0097]

[0098]

[0099] Wherein, in the same vehicle speed interval range, the rainfall compensation coefficients A1-A4 gradually increase, B1-B4 gradually increase, C1-C4 gradually increase; in the same sensitivity level, the rainfall compensation coefficients A1-C1 gradually increase, A2-C2 gradually increase, A3-C3 gradually increase, A4-C4 gradually increase. The rainfall 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 the wiper during the slow driving process is not high, and the real-time rainfall value can be corrected by the rainfall compensation coefficient to reduce the frequency and speed of continuous wiper wiping, so as to avoid unnecessary energy waste; the rainfall compensation coefficients B1-B4 and C1-C4 can be a value greater than 1, that is, the vehicle speed increases and / or the sensitivity level demand is set to be large, which represents that the demand for the wiper during the driving process is large, and the real-time rainfall can be corrected by the rainfall compensation coefficient to increase the frequency and speed of continuous wiper wiping, so as to ensure the clear vision of the driver. It should be noted that the above is only an exemplary vehicle speed interval range-sensitivity level-rainfall compensation coefficient table, which can be produced according to the results of the previous test, and the specific data in the vehicle speed interval range-sensitivity level-rainfall compensation coefficient table is not limited in the embodiment.

[0100] S340, determining the rainfall grade according to the real-time rainfall value.

[0101] S350, determining the real-time compensation rainfall value according to the rainfall grade and the rainfall compensation coefficient.

[0102] S360, determining the continuous wiper wiping sub-mode of the wiper in the continuous wiper wiping mode according to the real-time compensation rainfall value, and the wiping speed and / or the wiping frequency are different in different continuous wiper wiping sub-modes.

[0103] The embodiment determines the vehicle speed interval range where the real-time vehicle speed is located, and determines the rainfall compensation coefficient according to the vehicle speed interval range and the sensitivity level demand of the wiper to correct the real-time rainfall value, so that the wiper wiping mode is no longer determined by only the single factor of the real-time rainfall value, but the three factors of the real-time rainfall value, the real-time vehicle speed and the sensitivity level demand are considered comprehensively, so that the wiper works more in accordance with the actual demand, improves the wiper wiping effect, ensures the driving safety, and also avoids unnecessary energy waste of the wiper.

[0104] On the basis of the above embodiment, Figure 5 is another automatic wiper control method flowchart provided by the embodiment of the application, Figure 5 The above automatic wiper control method is further described. As Figure 5 The automatic wiper control method comprises the following steps:

[0105] S410, presetting the corresponding relationship of the real-time vehicle speed, the sensitivity level demand of the wiper and the rainfall compensation coefficient.

[0106] S420, a preset rain amount value and rain amount grade corresponding relationship.

[0107] S430, acquiring a real-time vehicle speed and a real-time rain amount value.

[0108] S440, determining a rain amount compensation coefficient according to the real-time vehicle speed and the wiper sensitivity grade requirement.

[0109] S450, determining a rain amount grade according to the real-time rain amount value.

[0110] S460, determining a real-time compensation rain amount value according to the rain amount grade and the rain amount compensation coefficient.

[0111] S470, determining a continuous wiper sub-mode of the wiper in the continuous wiper mode according to the real-time compensation rain amount value, the wiper speed and / or the wiper frequency being different in different continuous wiper sub-modes.

[0112] Specifically, the corresponding relationship between the real-time vehicle speed, the wiper sensitivity grade requirement and the rain amount compensation coefficient and the corresponding relationship between the rain amount value and the rain amount grade are calibrated through experiments, and the two corresponding relationships are stored in the processing unit 3. The processing unit 3 can query the rain amount compensation coefficient at this time according to the current real-time vehicle speed of the vehicle and the current wiper sensitivity grade requirement set by the user, and query the current rain amount grade according to the real-time rain amount value collected by the current rain amount sensor 2, in order to correct the continuous wiper mode of the wiper, so that the wiper works more in line with the actual demand.

[0113] For example, the corresponding relationship between the real-time vehicle speed, the wiper sensitivity grade requirement and the rain amount compensation coefficient can be: when the vehicle speed is lower than 20km / h, the wiper sensitivity grade requirement set by the driver is 1, and the corresponding rain amount compensation coefficient is 0.5; when the vehicle speed is between 20-40km / h, the wiper sensitivity grade requirement set by the driver is 2, and the corresponding rain amount compensation coefficient is 1; when the vehicle speed is between 40-60km / h, the wiper sensitivity grade requirement set by the driver is 3, and the rain amount compensation coefficient is 1.5. The corresponding relationship between the rain amount value and the rain amount grade can be: when the rain amount value is less than 10mm, the corresponding rain amount grade is 1; when the rain amount value is between 10mm-25mm, the corresponding rain amount grade is 2; when the rain amount value is between 25mm-50mm, the corresponding rain amount grade is 3.

[0114] It should be noted that, Figure 5An automatic wiper control method sequence is only exemplarily shown, actually, 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, the positions of step S410 and step S420 in the automatic wiper control method flow are not limited, as long as the corresponding relationship between the real-time vehicle speed, the wiper sensitivity level requirement and the rainfall compensation coefficient is preset before the rainfall compensation coefficient is determined according to the real-time vehicle speed and the wiper sensitivity level requirement, and the corresponding relationship between the rainfall value and the rainfall level is preset before the rainfall level is determined according to the real-time rainfall value.

[0115] Exemplarily, Figure 6 Another automatic wiper control method flowchart is provided according to an embodiment of the present application, as shown in Figure 6 The automatic wiper control method further includes the following steps:

[0122] S470, determining a continuous wiper sub-mode of the wiper in the continuous wiper mode according to the real-time compensation rainfall value, the wiper speeds and / or the wiper frequencies being different in different continuous wiper sub-modes.

[0123] On the basis of the above-mentioned embodiments, Figure 7 Another automatic wiper control method flowchart is provided according to an embodiment of the present application, Figure 7 The above-mentioned automatic wiper control method is further described. As shown in Figure 7 The automatic wiper control method includes the following steps:

[0124] S510, in a current detection stage, when the real-time rainfall value is greater than a starting wiper threshold value for the first time, controlling the wiper to perform a first wiper.

[0125] Specifically, during the driving process of the vehicle, when the real-time rain amount value on the windshield detected by the rain amount sensor 2 is greater than the wiper starting threshold value for the first time, the processing unit 3 generates and sends a control signal for wiper wiping once, the body control unit 5 receives and forwards the control signal to the wiper controller 4, and the wiper controller 4 controls the wiper 6 to perform the first wiping action to remove the rainwater on the windshield.

[0126] S520, when the real-time rain amount value is greater than the wiper starting threshold value for the second time, controlling the wiper to perform the second wiping.

[0127] Specifically, after the first wiping, the vehicle is still in the driving process, and when the real-time rain amount value on the windshield detected by the rain amount sensor 2 is greater than the wiper starting threshold value for the second time, the processing unit 3 generates and sends a control signal for wiper wiping once again, the body control unit 5 receives and forwards the control signal to the wiper controller 4, and the wiper controller 4 controls the wiper 6 to perform the second wiping action to remove the rainwater on the windshield.

[0128] S530, if the time interval between the second wiping and the first wiping is less than the first preset time interval t1, controlling the wiper to enter the supplementary wiping mode and controlling the wiper to perform wiping according to the supplementary wiping mode.

[0129] Specifically, when the wiper controller 4 controls the wiper 6 to perform single wiping, the wiper controller 4 feeds back the time of single wiping to the body control unit 5, the body control unit 5 forwards the time of single wiping to the processing unit 3, the processing unit 3 calculates the time interval between the two single wipings and compares the time interval with the first preset time interval t1, if the time interval between the two single wipings is less than the first preset time interval t1, it indicates that the rain is heavy, and the real-time rain amount value detected in a shorter time reaches the wiper starting threshold value 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 according to the supplementary wiping mode.

[0130] The embodiment predefines the wiper starting threshold value and the first preset time interval, and when the real-time rain amount value is greater than the wiper starting threshold value, single wiping is performed, and when the time interval between the two single wipings is greater than the first preset time interval, the wiper is controlled to enter the supplementary wiping mode, which improves the flexibility of wiper operation and makes the wiper operation more in line with actual needs.

[0131] On the basis of the above embodiment, Figure 8 is another automatic wiper control method flowchart provided by the embodiment of the application, Figure 8 The wiper is controlled to perform wiping according to the supplementary wiping mode will be described. As shown in the figure, the automatic wiper control method comprises the following steps: Figure 8

[0132] S610, in the current detection stage, when the real-time rain amount value is greater than the wiper starting threshold value for the first time, controlling the wiper to perform the first wiping.​

[0133] S620, when the second real-time rain value is greater than the wiping threshold, controlling the wiper to perform a second wiping.

[0134] S630, if the time interval between the second wiping and the first wiping is less than the first preset time interval t1, controlling the wiper to enter a make-up wiping mode, and controlling the wiper to perform wiping according to the make-up wiping mode.

[0135] S640, when the third real-time rain value is greater than the wiping threshold, recording the real-time time at this moment.

[0136] Specifically, during the driving of the vehicle, after the wiper 6 performs two wiping actions, when the third real-time rain value detected by the rain sensor 2 on the windshield is greater than the wiping threshold, the real-time time at this moment is recorded.

[0137] S650, if the time interval between the real-time time at this moment and the second wiping time is less than the second preset time interval t2, controlling the wiper to perform wiping at the second preset time interval t2 based on the second wiping time.

[0138] The second preset time interval t2 is less than the first preset time interval t1.

[0139] Specifically, based on the second wiping time of the wiper 6 fed back to the processing unit 3 by the wiper controller 4, the processing unit 3 calculates the time interval between the real-time time at which the third real-time rain value is greater than the wiping threshold and the second wiping time, and if the time interval between the real-time time and the second wiping time is less than the second preset time interval t2, it means that the time interval between the third single wiping time and the second wiping time is too small, and then the wiper 6 is controlled to perform the third wiping at the second preset time interval t2 based on the second wiping time.

[0140] S660, if the time interval between the real-time time at this moment 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, controlling the wiper to immediately wipe.

[0141] The third preset time interval t3 is greater than the first preset time interval t1.

[0142] 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 third time at which the real-time rainfall value is greater than the wiping threshold and the second wiping time, and if the time interval between the third time at which the real-time rainfall value is greater than the wiping threshold 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 indicates that the time interval between the third single wiping time and the second wiping time is moderate, similar to the time interval between the first wiping time and the second wiping time, and the wiper 6 can be controlled to immediately perform the third wiping.

[0143] S670, if the real-time rainfall value is less than the wiping threshold when the third preset time interval t3 is reached based on the second wiping time, the wiper is controlled to wipe at the third preset time interval t3.

[0144] 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 the third wiping when the third preset time interval t3 is reached.

[0145] 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 is 2.5s. If the third time at which the detected real-time rainfall value is greater than the wiping threshold 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 third time at which the detected real-time rainfall value is greater than the wiping threshold 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 rainfall sensor 2 does not detect a real-time rainfall value 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.

[0146] Optionally, the automatic wiper control method further comprises:

[0147] If the real-time rainfall is detected to be less than the wiping threshold when the third preset time interval t3 is reached based on the time of the last wiping, the supplementary wiping mode is exited, and the wiper is controlled to perform single wiping when the real-time rainfall value is greater than the wiping threshold.

[0148] The continuous preset number of times can be three, which is not limited in the embodiment

[0149] Specifically, when the continuous preset number of times is three, based on the time of the last wiping, if the real-time rainfall value of the windshield detected by the rainfall sensor 2 is not greater than the starting wiping threshold value within the third preset time interval t3 for three times, then every third preset time interval t3, a wiping is performed, and after a total of three wiping actions are completed, the wiper 6 exits the supplementary wiping mode and enters the control method in which the wiper performs single wiping when the real-time rainfall value is greater than the starting wiping threshold value.

[0150] Compared with the prior art, the single wiping control method no longer depends on only the single factor of whether the real-time rainfall value is greater than the starting wiping threshold value, but comprehensively considers whether the time interval between every two single wipings is too large, avoids too long or too short time intervals between two wipings, guarantees the continuity of wiper wiping, and improves the driving experience of the driver. In the supplementary wiping mode, when no real-time rainfall value greater than the starting wiping threshold value is detected within a certain time interval, the preset number of wiping strategies is increased to prevent rain on the front windshield, but the sensor does not detect rain and does not perform wiping, which affects the driver's vision and provides a safer driving experience for the driver.

[0151] Based on the same inventive concept, Figure 9 is a structural schematic diagram of an automatic wiper control device provided by an embodiment of the present application, as Figure 9 shown, the automatic wiper control device comprises an acquisition module 910, a compensation coefficient determination module 920, a rainfall grade determination module 930, a processing module 940, and a control module 950.

[0155] The processing module 940 is further configured to determine a real-time compensation rainfall value according to the rainfall grade and the rainfall compensation coefficient.

[0156] The control module 950 is configured to determine a continuous wiping sub-mode of the wiper in a continuous wiping mode according to the real-time compensation rainfall value, and the wiping speed and / or the wiping frequency are different in different continuous wiping sub-modes.
