[0001] The present application relates to the field of smart vehicle technology, and in particular to a vehicle windshield wiper control method, electronic equipment and vehicle. Background Art

[0002] With the continuous development of transportation, more and more users choose and buy motor vehicles to solve travel problems. Nowadays, in order to improve the user's experience and feelings when driving a vehicle, developers have designed and developed many automatic functions for vehicles. Among them, automatic wipers can provide drivers with timely wiping of the windshield to ensure a clear field of vision for the driver.

[0003] At present, automatic wipers mainly rely on rain sensors installed on the windshield to monitor the amount of rain and control the switch of the automatic wipers accordingly. However, the rain sensors are prone to detection errors. Therefore, how to improve the control accuracy and efficiency of automatic wipers has become one of the issues studied by technicians in related fields. Summary of the invention

[0022] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0023] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0024] Before explaining the embodiments and implementation methods of the present application, the background technology and the problems to be solved are explained first. Automatic wiper technology mainly relies on the rain sensor installed on the windshield to identify the amount of rain. According to the different degrees of rain, the wiper is adaptively controlled to wipe and sweep, so as to ensure a clear field of vision for the driver and prevent traffic accidents. The rain sensor mainly adopts the infrared principle, that is, the infrared transmitter in the rain sensor emits light to the windshield, and after being reflected by the windshield, the infrared receiver in the rain sensor receives the reflected light. However, due to the presence of rain on the windshield due to rain, the reflection of light by the windshield changes. Therefore, in the two cases where there is no rain and there is rain on the windshield at the installation position of the rain sensor, the reflected light received by the infrared receiver in the rain sensor also changes accordingly. Based on this principle, the rain outside the car can be analyzed so as to adaptively turn on the wiper for wiping.

[0025] However, when there is water locally at the location where the rain sensor is installed on the windshield, or when the vehicle passes through a continuously changing ambient light brightness (for example, a tree-lined road where the sun shines through, and the branches and leaves of the trees make the sun shining on the windshield flicker), it is easy for the rain sensor to misidentify rain, causing the vehicle to control the wipers to turn on, affecting the driver's driving. Therefore, the present application proposes a vehicle wiper control method to solve the problem of misjudgment of the rain sensor, and the specific embodiments and implementation methods are as follows.

[0026] Figure 1A vehicle windshield wiper control method provided in an embodiment of the present application can be applied to the case where the execution standard information corresponding to the functional modules in the vehicle is displayed. The vehicle windshield wiper control method provided in an embodiment of the present application can be executed by a vehicle windshield wiper control device, which can be integrated into an electronic device by means of hardware and / or software, such as integrated into a vehicle controller. Figure 1 , the method provided in the embodiment of the present application comprises the following steps:

[0027] S110, obtaining real-time rainfall data detected by a rain sensor of the current vehicle, and rainfall characterization data of the environment in which the current vehicle is located.

[0028] The current vehicle may be any vehicle driven by the user, and the embodiment of the present application does not limit the basic data such as the power type and body size of the current vehicle. The real-time rainfall data may be real-time data obtained by detecting rainfall using a rain sensor disposed on the windshield of the current vehicle. It should be noted that due to local water accumulation on the windshield or the vehicle passing through a location where the light changes continuously, it is easy for the rain sensor to obtain detection data even when it is not raining. Therefore, the real-time rainfall data is not completely accurate.

[0029] The environment in which the current vehicle is located is also the surrounding environment in which the current vehicle is located. Correspondingly, the rainfall characterization data can be the relevant reference data reflecting the rain in the environment, and the rainfall characterization data can be used to characterize the rainfall conditions in the surrounding environment. It should be noted that the rainfall characterization data can be data of any dimension except the real-time rainfall data detected by the rain sensor. For example, it may include but is not limited to image data that can identify rainfall detected by a visual sensor, sound data emitted by rain hitting the vehicle body detected by an acoustic sensor, and humidity data outside the vehicle detected by a humidity sensor, etc. The embodiments of the present application are not specifically limited here. Whether it is real-time rainfall data or rainfall characterization data, both can be directly acquired by real-time detection by sensors of different dimensions inherent to the vehicle.

[0030] S120: Determine the real-time rainfall intensity of the current environment of the vehicle according to the rainfall characterization data.

[0031] Among them, the real-time rainfall intensity can be used to characterize the size of the rain in the environment described by the current vehicle. Different from the precipitation (rainfall within 24 hours) data in the field of meteorology, the real-time rainfall intensity emphasizes the degree of short-term rainfall, such as short-term heavy rainfall or short-term weak rainfall. The real-time rainfall intensity is analyzed by rainfall characterization data, and the intensity of rainfall is judged by rainfall characterization data of different dimensions respectively. Combined with the analysis and judgment results of rainfall characterization data of different dimensions, the real-time rainfall intensity of the environment in which the current vehicle is located can be determined. Continuing with the previous example, image data, sound data and humidity data can all reflect the rainfall conditions in the environment from different dimensions, and then determine the real-time rainfall intensity. The real-time rainfall intensity can be divided into two categories: heavy rainfall or weak rainfall. For example, heavy rainfall can be rain with a rainfall of 16 mm or more within 1 hour, and weak rainfall can be rain with a rainfall of less than 16 mm within 1 hour. More intensity levels can also be divided according to the quantized values ​​of rainfall characterization data of different dimensions to provide a basis for subsequent wiper control. The embodiment of the present application is not limited here.

[0032] S130: Controlling the windshield wipers of the current vehicle according to the real-time rainfall intensity and real-time rainfall data.

[0033] It is worth reminding that in the above steps, the real-time rainfall intensity is not judged with reference to the real-time rainfall data detected by the rain sensor. This case aims to verify the real-time rainfall data using the real-time rainfall intensity determined by the rainfall characterization data detected by sensors in other dimensions. Real-time rainfall data can only reflect the results of the rain sensor detection, while the real-time rainfall intensity is obtained based on the rainfall characterization data of different dimensions, so as to judge whether it is really raining outside the car. Combining the rainfall intensity and rainfall data can further determine the amount of rainfall, so as to control the wipers for wiping, for example, according to the strength of the real-time rainfall intensity and the size of the real-time rainfall data, the wiping speed of the wipers can be controlled. Of course, while controlling the wipers, you can also control the windows of the current vehicle synchronously. When it is confirmed that the wipers need to be turned on, it means that it is raining, and all the windows of the vehicle can be closed at the same time.

[0034] The technical solution of the embodiment of the present application determines the real-time rainfall intensity outside the vehicle based on the rainfall characterization data of the current vehicle environment. The rainfall characterization data of different dimensions can analyze the intensity of rainfall from different angles, so as to make a comprehensive judgment, improve the accuracy of the judgment on real-time rainfall, and indirectly improve the accuracy of wiper control; the real-time rainfall intensity is combined with the real-time rainfall data obtained by the current vehicle detection to control the wipers, so as to solve the problem of misjudgment of whether it is raining and how heavy the rain is due to external environmental reasons caused by the rain sensor, and further effectively prevent the problem of the current vehicle relying solely on the rain sensor to detect rainfall, resulting in the misjudgment of the wipers starting incorrectly, thereby effectively improving the vehicle's judgment accuracy on rain in the external environment, and more accurate control of the wiper operation can also improve the efficiency of wiper control to a certain extent.

[0035] In an optional implementation, controlling the windshield wiper of the current vehicle according to the real-time rainfall intensity and the real-time rainfall data in S130 may include:

[0036] S131. Determine whether there is a need to turn on the windshield wipers of the current vehicle based on the real-time rainfall intensity and real-time rainfall data.

[0037] Among them, the opening requirement can be understood as whether the wipers of the current vehicle need to be turned on. It should be noted that there may be errors in the real-time rainfall data. For example, water has tension, and it is easy to accumulate a small amount of water locally on the windshield. If water appears on the windshield where the rain sensor is installed, the rain sensor is easy to generate real-time rainfall data and provide it to the vehicle, so that the vehicle itself recognizes the external environment as "light rain"; in addition, when the vehicle passes through a tree-lined road, the sunlight is blocked by the branches and leaves of the trees, forming an ambient light with continuously changing light. The rain sensor on the windshield is also easy to generate real-time rainfall data and provide it to the vehicle. At this time, the real-time rainfall data is easy to make the vehicle itself recognize the external environment as "heavy rain". If the wipers are controlled only by relying on the rain sensor to detect the real-time rainfall data, it is easy to generate real-time rainfall data even though it is not raining.

[0038] Therefore, firstly, the real-time rainfall intensity and real-time rainfall data are used to determine whether the wipers need to be turned on. When the real-time rainfall data detected by the rain sensor is consistent with the real-time rainfall intensity determined by sensors of other dimensions, the weather conditions outside the vehicle can be determined. If it is confirmed that it is raining, the need to turn on the wipers is also confirmed. If the real-time rainfall data detected by the rain sensor and the real-time rainfall intensity determined by sensors of other dimensions are inconsistent, it is necessary to further determine the weather conditions outside the vehicle based on the real-time rainfall intensity and real-time rainfall data, so as to confirm whether the wipers need to be turned on. For example, when the real-time rainfall data shows that there is rain, and the real-time rainfall intensity determined by the vehicle is zero (i.e., it is not raining), it is considered that there is an error in the real-time rainfall data, so there is no need to turn on the wipers for the time being.

[0039] S132: In response to a demand for the wipers to be turned on, a wiping mode of the wipers is determined according to real-time rainfall intensity and real-time rainfall data to control the wipers to work.

[0040] The wiping mode of the wiper may be a working mode when the wiper is wiping the windshield, for example, it may include but is not limited to information such as wiping frequency, wiping speed and wiping time.

[0041] If the real-time rainfall data detected by the rain sensor or the real-time rainfall intensity determined by the sensors of other dimensions show that it is raining outside the car, then it is determined that the wipers need to be turned on. Since the wipers have different wiping modes, they can be adaptively adjusted according to the specific raining conditions. Both the real-time rainfall intensity and the real-time rainfall data can reflect the instantaneous or short-term rainfall level outside the car to a certain extent. According to the level of the instantaneous and / or short-term rainfall level, the wiper wiping mode is controlled to adapt to different raining conditions.

[0042] In the above-mentioned implementation mode, based on the real-time rainfall intensity and the real-time rainfall data, it is determined whether there is a need to turn on the wipers of the current vehicle, and it can be verified by the real-time rainfall intensity on the basis of the real-time rainfall data, so as to judge whether it is really raining and whether it is really necessary to turn on the wipers, and the raining situation can be judged more accurately; then in response to the need to turn on the wipers, the wiping mode of the wipers is determined based on the real-time rainfall intensity and the real-time rainfall data, and the operation of the wipers is controlled. When the wipers need to be turned on, the wiping mode of the wipers is further determined to ensure the efficiency of the wipers.

[0043] In a further optional implementation manner, determining whether there is a need to turn on the windshield wipers of the current vehicle according to the real-time rainfall intensity and the real-time rainfall data in S131 may include:

[0044] In response to the real-time rainfall data meeting the preset rainfall threshold and the real-time rainfall intensity being zero, it is determined that there is no need to turn on the wipers.

[0045] Among them, the preset rainfall threshold can be the basis for judging whether it is raining outside the vehicle based on the real-time rainfall data. For example, when the real-time rainfall data meets the preset rainfall threshold, it is judged that it may be raining outside the vehicle through the dimension of the rain sensor. When the real-time rainfall data does not meet the preset rainfall threshold, it is judged that it may not be raining outside the vehicle through the dimension of the rain sensor. Of course, the preset rainfall threshold can also be divided into multiple subdivision thresholds in detail, corresponding to the intensity of the rainfall, which is not limited here.

[0046] When the real-time rainfall data meets the preset rainfall threshold and the real-time rainfall intensity is zero, it is equivalent to the current vehicle's rain sensor detecting that it is raining outside the vehicle, but sensors in other dimensions detect that it is not raining outside the vehicle. At this time, it is temporarily determined that there is no need to turn on the wipers, that is, it is temporarily believed that the data detected by the rain sensor may be wrong.

[0047] In the above-mentioned implementation mode, for possible detection errors of the rain sensor, the real-time rainfall data detected by the rain sensor is verified with the real-time rainfall intensity determined by sensors of other dimensions, so as to prevent the rain sensor from being affected by the external environment and causing misdetection and misjudgment problems, which helps to improve the accuracy of rainfall judgment, and thus helps to improve the accuracy and efficiency of wiper control.

[0048] In a further optional implementation manner, determining whether there is a need to turn on the windshield wipers of the current vehicle according to the real-time rainfall intensity and the real-time rainfall data in S131 may also include:

[0049] In response to the fact that the time duration during which the real-time rainfall data meets the preset rainfall threshold exceeds the preset time duration, and the real-time rainfall intensity is not zero, it is determined that there is a need to turn on the wipers.

[0050] Among them, the real-time rainfall intensity can be divided into zero (no rain) and non-zero (including weak rain and heavy rain), where weak rain and heavy rain represent that it is raining instantly or for a short time in the current environment of the vehicle. It can be understood that if the rain sensor continues to provide real-time rainfall data to represent rain, and the state of continuously providing data is maintained for a certain period of time, at this time, the real-time rainfall intensity judged by other dimensions is not zero (that is, there is weak rain or heavy rain), then it can be determined that it is raining outside the current vehicle, so the wipers need to be turned on.

[0051] In addition, after the aforementioned implementation method determines that there is no need to turn on the wipers, the real-time rainfall data detected by the rain sensor continues to be obtained, and the duration for which the rainfall data meets the preset rainfall threshold is determined. If the duration for which the real-time rainfall data detected meets the preset rainfall threshold does not exceed the preset duration, it can be confirmed that there is indeed no need to turn on the wipers.

[0052] It can be understood that in the aforementioned embodiment, the judgment of the real-time rainfall data is verified by the real-time rainfall intensity. Then, when the real-time rainfall data is continuously acquired subsequently, it is found that the real-time rainfall data does not meet the rain standard. In this case, it can be confirmed that it is not raining outside the car at this time, so there is no need to turn on the wipers.

[0053] In combination with the above-mentioned embodiment, illustratively, the rain sensor of the current vehicle sends real-time rainfall data, indicating that it is raining outside the vehicle, and at the same time, the real-time rainfall intensity determined by the sensors of other dimensions is zero, that is, the sensors of other dimensions comprehensively believe that it is not raining outside the vehicle, and it is temporarily considered that there is no need to turn on the wipers. At this time, the real-time rainfall data sent by the rain sensor is continuously obtained. If the real-time rainfall data disappears within a preset time (for example, within 5 seconds), that is, the transmission duration of the real-time rainfall data does not continue to exceed the preset time, then the rain sensor also determines that there is no rainfall, so it is determined that the wipers do not need to be turned on.

[0054] Then, if the duration that the real-time rainfall data meets the preset rainfall threshold exceeds the preset duration, that is, after judging that the wipers do not need to be turned on temporarily in the aforementioned embodiment, the rain sensor continues to detect and send real-time rainfall data within a certain period of time, indicating that the rain sensor still believes that it is raining outside the vehicle. At this time, the real-time rainfall intensity is re-acquired. If the rainfall intensity comprehensively judged by the sensors of other dimensions is not zero, but heavy rainfall or weak rainfall, it means that the rain sensor and the sensors of other dimensions both believe that it is raining outside the vehicle, then it can be confirmed that there is a need to turn on the wipers. Continuing with the previous example, the rain sensor of the current vehicle sends real-time rainfall data, indicating that it is raining outside the vehicle. At the same time, the real-time rainfall intensity judged by the sensors of other dimensions is zero, that is, the sensors of other dimensions comprehensively believe that it is not raining outside the vehicle, then it is temporarily considered that there is no need to turn on the wipers. At this time, the real-time rainfall data sent by the rain sensor is continuously obtained. If the real-time rainfall data has been sent within the preset time period (for example, within 5 seconds) and the detection and sending have never stopped, and the real-time rainfall intensity determined by the comprehensive judgment of other dimensional sensors has changed from zero to "heavy rainfall" or "weak rainfall", then the rain sensor and other dimensional sensors both judge that it is raining outside the car, and the wipers need to be turned on.

[0055] In the above-mentioned embodiment, based on the judgment that it is not necessary to turn on the wiper in the aforementioned embodiment, the detection data of the rain sensor and other dimensional sensors are further continuously obtained to judge whether it is really raining outside the vehicle. This can accurately provide the vehicle with autonomous weather judgment, help reduce the error rate of judging rain only by relying on the rain sensor, and improve the accuracy and efficiency of wiper control.

[0056] In an optional implementation, in response to the need to turn on the wiper, determining the wiping mode of the wiper according to the real-time rainfall intensity and the real-time rainfall data to control the wiper to work in S132 may include:

[0057] B1. In response to a demand to turn on the wipers and the real-time rainfall intensity is heavy rainfall, a target wiper speed corresponding to the real-time rainfall data is queried in a preset correspondence between the real-time rainfall and the wiper speed.

[0058] The correspondence between the real-time rainfall and the wiping speed can be a pre-set comparison of different wiping speeds according to the rainfall intensity or rainfall size. For example, when the rainfall is weak or small, the wiping speed is slower; similarly, when the rainfall is strong or weak, the wiping speed is faster. Of course, the correspondence between the rainfall data detected by the specific rain sensor and the wiping speed with more detailed quantitative values ​​can be set by technicians in the relevant field based on a large number of experiments or actual conditions, and the embodiments of the present application do not limit this.

[0059] It is understandable that if the real-time rainfall intensity at this time is heavy rainfall, it means that the rainfall is relatively strong, and it is necessary to query the corresponding target scraping speed in the corresponding relationship based on the real-time rainfall data.

[0060] B2. Control the wipers to wipe continuously at the target wiping speed.

[0061] The wipers are controlled to work according to the target wiping speed determined in the previous steps, so as to adapt to the situation of heavy rainfall.

[0062] In the above implementation, in the case of heavy rainfall, the target wiping speed corresponding to the real-time rainfall data is queried according to the corresponding relationship between the real-time rainfall and the wiping speed, so as to control the wipers to work according to the target wiping speed. This can ensure that when the rainfall is heavy, the wiping speed of the wipers can fully cope with the rainfall level, thereby providing the driver with a clear field of vision and ensuring driving safety.

[0063] In another optional implementation, in response to the need to turn on the wiper, determining the wiping mode of the wiper according to the real-time rainfall intensity and the real-time rainfall data to control the wiper to work in S132 may also include:

[0064] In response to the need to turn on the wipers and the real-time rainfall intensity is weak rainfall, the wipers are controlled to perform interval wiping according to a preset interval wiping frequency.

[0065] The interval wiping frequency can represent how often the wipers wipe. When the sensors in other dimensions comprehensively determine that the rainfall intensity is weak, it means that the rainfall level is not strong, then there is no need for continuous wiping, and only intermittent wiping according to the preset interval wiping frequency is required.

[0066] It should be noted that the weak rainfall situation actually corresponds to very light rain in real life, which can be understood as rainfall that cannot affect the driver's observation through the windshield in a short period of time. Therefore, there is no need to consume energy to control the wipers to wipe continuously.

[0067] In the above embodiment, in the case of light rainfall, the wipers are controlled to perform intermittent wiping according to a preset interval wiping frequency. This can ensure that when the rainfall is light, the wiping frequency of the wipers can fully cope with the rainfall level, thereby providing the driver with a clear field of vision, ensuring driving safety while saving vehicle energy.

[0068] In yet another optional embodiment, the rainfall characterization data includes an environmental image of the current vehicle's environment, rain sound data detected by an acoustic sensor of the current vehicle, and humidity data detected by a humidity sensor of the current vehicle;

[0069] Determining the real-time rainfall intensity of the current environment of the vehicle according to the rainfall characterization data includes:

[0070] determining a first rainfall index according to the environmental image;

[0071] Determine a second rainfall index based on the rain sound data;

[0072] Based on the humidity data, the third rainfall index is determined;

[0073] The real-time rainfall intensity is determined according to the weighted results of the first rainfall index, the second rainfall index and the third rainfall index.

[0074] Among them, the environmental image can be an image of the external environment of the vehicle acquired by the outward-facing visual device inherent in the current vehicle. The rain sound data can be the data of the sound of rain hitting the vehicle body detected by the acoustic sensor installed on the current vehicle. The humidity data can be the humidity information outside the vehicle detected by the humidity sensor installed on the current vehicle. It is worth mentioning that the environmental image can be better for identifying heavy rainfall; rain sound data and humidity data are very effective for detecting weak rainfall. Therefore, sensor data of these dimensions can more accurately help vehicles identify real-time rainfall intensity.

[0075] The first rainfall index may be an indicator parameter used to reflect the degree of rain in the environmental image. For example, the environmental image obtained by the current vehicle may be analyzed by a pre-trained image processing model, and the degree of rain in the environment may be analyzed from the perspective of the image. The model inputs the environmental image outside the vehicle obtained by continuous acquisition, and the model outputs the first rainfall index. Of course, the image processing model may be pre-trained by technicians in related fields, such as using a convolutional neural network model, etc., and the embodiments of the present application are not limited to this.

[0076] The second rainfall index may be an indicator parameter used to reflect the rain sound data to judge the degree of rain. For example, different rainfall index values ​​may correspond to different threshold intervals of the decibel value of the rain sound data, thereby determining the second rainfall index.

[0077] The third rainfall index may be an indicator parameter used to reflect humidity data to determine the degree of rain. For example, different humidity index values ​​may correspond to different threshold intervals of humidity values ​​in the humidity data, thereby determining the third rainfall index.

[0078] The weighted sum of the three types of rainfall indices obtained by sensors in each dimension is calculated. The weights corresponding to different rainfall indices can be set by technicians in the relevant field based on a large number of experiments or manual experience, and are not limited here. The real-time rainfall intensity is determined based on the weighted results obtained by calculation. For example, different real-time rainfall intensity indicators (such as heavy rainfall or light rainfall) can be set in advance, as well as the numerical range of the weighted results belonging to heavy rainfall or light rainfall, etc.

[0079] In the above implementation, the data obtained from the vehicle's external perception in three dimensions, namely, vision, acoustics and humidity, are analyzed to obtain three types of rainfall indexes respectively, and the real-time rainfall intensity is determined according to the weighted results obtained by weighted calculation, so that more information from different dimensions can be referred to and whether it is raining outside the vehicle can be comprehensively judged. In particular, vision is more likely to identify heavy rainfall, while sound and humidity are more likely to identify weak rainfall, which can better distinguish the intensity of rainfall, so as to provide the vehicle with more accurate rainfall intensity information as a reference, which helps to improve the accuracy and efficiency of wiper control.

[0080] In an optional implementation manner, obtaining the real-time rainfall data detected by the rain sensor of the current vehicle and the rainfall characterization data of the environment in which the current vehicle is located in S110 may include:

[0081] S111. Acquire real-time rainfall data detected by a rainfall sensor of the current vehicle.

[0082] S112: In response to the real-time rainfall data meeting a preset rainfall threshold, obtaining rainfall characterization data of the current vehicle.

[0083] It should be noted that the real-time rainfall data detected by the rain sensor and the rainfall characterization data detected by other dimensional sensors can be acquired in a certain order. Specifically, after the real-time rainfall data identified by the rain sensor meets the preset rainfall threshold, other dimensional sensors are enabled to obtain the rainfall characterization data corresponding to each dimension to verify the raining conditions determined by the rain sensor.

[0084] The above implementation provides an acquisition order, or a condition for acquiring rainfall characterization data, for acquiring real-time rainfall data and rainfall characterization data. Only when the real-time rainfall data meets the preset rainfall threshold value can the rainfall characterization data of each dimension detected by the sensors of other dimensions be acquired. Not turning on the sensors of other dimensions at the same time can further save collection and computing resources and improve the utilization efficiency of vehicle energy.

[0085] It should be noted that the method of the embodiment of the present application can be performed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present application, and the multiple devices will interact with each other to complete the described method.

[0086] It should be noted that the above describes some embodiments of the present application. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be performed in an order different from that in the above embodiments and still achieve the desired results. In addition, the processes depicted in the accompanying drawings do not necessarily require the specific order or continuous order shown to achieve the desired results.
