Abstract

The invention discloses a demisting method of a vehicle front-view camera, a demisting device of the vehicle front-view camera, a vehicle, a computer program product and a computer readable storage medium. When the defrosting function of the vehicle is started, especially under the condition that the defrosting function of the front windshield is started, the fogging probability of the front windshield is high, and in order to guarantee the defogging effect of the front view camera and further improve the visual perception performance of the vehicle, the window heating function and the defrosting function of the vehicle can be linked; automatically starting a window heating function; when closed, heating of the window can be delayed to be closed to avoid fogging again in a short time. Meanwhile, in order to reduce unnecessary energy consumption, the start-stop state of window heating can be dynamically adjusted based on the start-stop state of the intelligent driving function associated with the front-view camera. When the vehicle voltage is low or the battery capacity is lower than the preset value, the window heating function can be preferentially closed to ensure that the vehicle is started. On the basis, due to the fact that the window heating area and the front windshield heating area are partially overlapped, when the front windshield heating function is started, the window heating function can be closed to reduce the risk that the front windshield and the front camera are damaged, and energy consumption is reduced.

Description

Technical Field

Background Art

[0002] The vehicle's forward-looking camera is the core of its visual perception and is usually installed on top of the front windshield in the cabin. However, when the windshield is foggy, the camera's visual perception ability will be significantly reduced, and even pose a potential threat to driving safety.

[0003] In the related technology, the fogging risk of the windshield can be determined by monitoring the temperature difference and air humidity inside and outside the car, or by directly identifying the fog state through a camera, and defogger can be performed when the fogging risk is high. However, there are errors in the collection of the temperature difference and air humidity inside and outside the car, which makes it difficult to accurately set the trigger threshold of the defogger function; at the same time, the camera's recognition of fog is easily affected by environmental interference and there is a risk of misjudgment. This makes it difficult for the existing front-view camera defogger method to respond accurately and reliably in actual applications, resulting in poor defogger effect of the front-view camera, affecting driving safety. Summary of the invention

[0004] The present application provides a defog method for a vehicle's front-view camera, a defog device for a vehicle's front-view camera, a vehicle, a computer program product, and a computer-readable storage medium, which can accurately and reliably activate the front window heating function of the front-view camera, improve the defog effect of the front-view camera, and thus ensure driving safety.

[0005] In a first aspect, the present application provides a defogging method for a vehicle front-view camera, comprising:

[0006] Activate the heated windows of the vehicle's front view camera when the vehicle's defrost function is activated.

[0007] In some embodiments, after starting the window heating function of the front view camera of the vehicle, the method further includes:

[0008] The start and stop status of the window heating function is controlled based on the start and stop status of the preset intelligent driving function.

[0009] In some embodiments, controlling the start / stop state of the window heating function based on the start / stop state of the preset intelligent driving function includes:

[0010] If the preset intelligent driving is off, the window heating function will be turned off;

[0011] If the preset intelligent driving is in the activated state, the window heating function will remain activated.

[0012] In some embodiments, when the window heating function is in an activated state, the method further includes:

[0013] After determining that the defrost function is switched off, the window heating function is switched off after a preset time.

[0014] In some embodiments, when the window heating function is in an activated state, the method further includes:

[0015] When the vehicle's voltage is in a low voltage state and the vehicle's battery power is less than a preset power level, the window heating function is turned off.

[0016] In some embodiments, when the window heating function is in an activated state, the method further includes:

[0017] If the vehicle's heated windshield is on, turn off the heated windows.

[0018] In a second aspect, the present application provides a defogger device for a vehicle front-view camera, comprising:

[0019] The first control module is used to start the window heating function of the front view camera of the vehicle when the defrost function of the vehicle is started.

[0020] In a third aspect, the present application provides a vehicle comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps of the method of the first aspect when executing the computer program.

[0021] In a fourth aspect, the present application provides a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the steps of the method of the first aspect are implemented.

[0022] In a fifth aspect, the present application provides a computer program product, which includes a computer program. When the computer program is executed by one or more processors, it implements the steps of the method of the first aspect.

[0023] The first aspect of the present application has the beneficial effect compared with the prior art that the defrost function of the vehicle generally includes two modes: manual start and automatic start, wherein the manual start depends on the driver's visual perception and driving needs, and can be enabled in time according to the actual situation; the automatic start makes the defrost judgment more accurate through the comprehensive judgment of multi-dimensional data. In contrast, the judgment accuracy of the fogging of the front windshield relying on single-dimensional data or the front-view camera in the related art is relatively low. Therefore, the present application links the front-view camera window heating function with the defrost function, which can significantly improve the accuracy of the window heating start timing. In addition, since the fog or frost on the front windshield usually spreads from the edge to the center, and the front-view camera window area is usually far away from the edge, the defrost function starts to start when the fog or frost on the windshield appears at the edge. The window heating function can start the window heating function in advance before the fog or frost spreads to the field of view of the front camera by linking with the defrost function, effectively reducing the impact of fog or frost on the camera, and further improving the stability of visual perception and the reliability of driving.

[0024] It can be understood that the beneficial effects of the second to fifth aspects mentioned above can be found in the relevant description of the first aspect mentioned above, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0031] In the related technology, although the risk of fogging of the windshield can be determined by monitoring the temperature difference and air humidity inside and outside the car, or by directly identifying the fog state through the camera, and the defog function can be triggered when the risk is high to ensure the clarity of the camera. However, there are inherent errors in the collection of the temperature difference and air humidity inside and outside the car, which makes it difficult to accurately set the trigger threshold of the defog function; at the same time, the camera's recognition of fog is easily affected by factors such as ambient light and stains, and there is a risk of misjudgment. This makes it difficult for the existing front-view camera defog method to respond accurately and reliably in actual applications, reducing the effect of the front-view camera defog, and even affecting driving safety.

[0032] In order to solve this problem, this application deeply analyzes the fundamental reasons why the front-view camera defog method is difficult to respond accurately and reliably in practical applications, and finds that the main problem is that although the temperature difference between the inside and outside of the car and the air humidity are closely related to whether the windshield is fogged, they are not the only determining factors; and the front-view camera's fogging risk judgment is limited by its field of view, and it is difficult to fully perceive the state of the front windshield, resulting in inaccurate or delayed fogging risk judgment. Therefore, the existing technology that relies on single-dimensional data or front-view cameras for judgment has low accuracy and is difficult to meet actual needs.

[0033] Considering the activation mode of the vehicle defrost function, whether it is manual activation or automatic activation, the risk judgment of windshield fogging or frosting is better than the judgment of fogging risk in the front camera defrosting method. Among them, manual activation relies on the driver's visual perception and actual driving needs, and can trigger the defrost function flexibly and timely; while automatic activation combines multi-dimensional data such as the temperature difference between the inside and outside of the vehicle, humidity, dew point, and detection data of multiple points on each windshield for comprehensive judgment, making the defrost judgment more accurate and reliable.

[0034] Therefore, the present application proposes a defog method for a vehicle front-view camera, which links the window heating function of the front-view camera with the defrosting function of the vehicle, and can accurately and reliably start the window heating function of the front-view camera, thereby improving the defog effect of the front-view camera and ensuring driving safety. The defog method proposed in the present application will be described below through specific embodiments.

[0035] The vehicle defog method provided in the embodiment of the present application can be applied to the vehicle or other electronic devices, such as other electronic devices that establish a communication connection with the vehicle to control the vehicle, such as mobile phones, tablet computers, vehicle-mounted devices, augmented reality (AR) / virtual reality (VR) devices, laptop computers, ultra-mobile personal computers (UMPC), netbooks, personal digital assistants (PDA), etc. The embodiment of the present application does not impose any restrictions on the specific type of electronic devices.

[0036] In order to illustrate the technical solution proposed in this application, each embodiment will be described below using a vehicle as the execution subject.

[0037] Figure 1 A schematic flow chart of a defogging method for a vehicle front-view camera provided by the present application is shown, and the defogging method for a vehicle front-view camera includes:

[0038] Step 110: When the defrost function of the vehicle is activated, the vehicle activates the window heating function of the front view camera of the vehicle.

[0039] The window heating function is the core means of defogger for the front-view camera, and the accuracy of its activation timing is crucial. If it is activated too early, it is easy to cause unnecessary energy loss; if it is activated too late, it may affect the clarity of the front-view camera, thereby weakening the vehicle's visual perception ability.

[0040] To improve the accuracy of the start-up timing of the window heating function, the vehicle no longer relies solely on relevant data (such as the temperature difference between inside and outside the vehicle, air humidity data or image data collected by the front-view camera) to determine the start-up timing. Instead, the window heating function is linked with the vehicle's mature and stable defrost function to ensure that the window heating is started more efficiently and reliably.

[0041] The vehicle defrost function activation method, whether manual or automatic, is significantly better than the defrosting method that relies on the front-view camera in judging the risk of windshield fogging or frosting. This is mainly reflected in the following two aspects:

[0042] On the one hand, manually starting the defrost function depends on the driver's visual perception and driving needs, and is highly flexible and timely. The driver can directly observe the status of the entire windshield with the naked eye, without relying on indirect perception by the equipment. Especially in complex environments (such as light changes, local fogging, etc.), the driver's judgment is often more intuitive and accurate. In addition, the driver can trigger the defrost function in time according to specific driving scenarios (such as high-speed driving or rainy and snowy weather) to avoid potential safety risks.

[0043] On the other hand, the automatic start-up defrost function makes a comprehensive judgment from multiple dimensions by combining the temperature difference between the inside and outside of the car, air humidity, dew point, and sensor detection data at multiple points on the windshield. This method not only overcomes the errors that may be caused by one-dimensional data (such as temperature difference or humidity), but also can analyze the dynamic changes of multiple related factors in real time, so as to more accurately predict the risk of fogging or frosting. In addition, automatic start-up is usually based on mature sensor networks and algorithms, with rapid response capabilities, and can trigger the defrost function at the early stage of fogging, effectively preventing the fog from spreading to the extent of affecting the field of vision.

[0044] In contrast, the defog method of the front-view camera is limited by its field of view and can only identify the status of a specific area. At the same time, its recognition accuracy is easily affected by external environmental interference (such as changes in lighting or obstructions caused by stains), making it difficult to fully and reliably perceive the overall condition of the windshield.

[0045] It can be seen that the advantages of linking the window heating function with the defrost function are obvious. That is, after the defrost function of the vehicle is activated, the vehicle actively turns on the window heating function, which can not only rely on the more strict and accurate judgment of the risk of fogging or frosting when the defrost function is activated, and then accurately and reliably determine the timing of starting the front camera window heating function, but also significantly improve the defog effect of the front camera. This linkage mechanism effectively avoids the problem of starting the window heating function too early or too late, ensuring that the front camera can maintain a clear view in various environments, thereby further ensuring the stability and reliability of the vehicle's intelligent driving function.

[0046] In this embodiment, after the vehicle links the front camera window heating function with the defrost function, the timing accuracy of window heating activation can be significantly improved. In addition, since the fog or frost on the front windshield usually spreads from the edge to the center, and the front camera window area is usually far away from the edge, the defrost function starts when the fog or frost on the windshield appears at the edge. The window heating function is linked with the defrost function to start the window heating function in advance before the fog or frost spreads to the field of view of the front camera, effectively reducing the impact of fog or frost on the camera, and further improving the stability of visual perception and driving safety.

[0047] In some embodiments, the clarity of the front-view camera directly affects the visual perception ability of the vehicle, which is particularly important for the preset intelligent driving function that relies on visual perception. However, when the preset intelligent driving function is not enabled, the vehicle's dependence on the front-view camera is low, and the operation of the window heating function will bring certain energy consumption; therefore, in order to turn on the window heating function as much as possible when necessary to reduce the overall energy consumption of the vehicle, the vehicle can further combine the start and stop status of the preset intelligent driving function to dynamically control the start and stop of the window heating function, thereby achieving a balance between energy consumption and functional requirements.

[0048] Specifically, the vehicle can control the start and stop status of the window heating function based on the start and stop status of the preset intelligent driving function. The consistency of the start and stop status of the two functions can improve energy utilization efficiency and avoid unnecessary energy consumption while ensuring the stability of the preset intelligent driving function. At the same time, on the basis of the linkage between the window heating function and the defrost function, it is further linked with the preset intelligent driving function, and the operation strategy of the window heating function can be dynamically adjusted according to the actual use scenario of the vehicle, which not only ensures the clarity of the front camera and the stability of the intelligent driving function, but also effectively reduces the overall energy consumption.

[0049] For example, considering that intelligent driving functions such as high-speed NOA (Navigate on Autopilot), support for urban NOA, and memory driving are highly dependent on the visual perception capabilities of the front-view camera, these functions can be identified as preset intelligent driving functions. The normal operation of these functions requires the front-view camera to always maintain a clear field of view. Therefore, when any of the preset intelligent driving functions is enabled, the vehicle can maintain the window heating function to ensure the defog effect and clarity of the front-view camera, thereby ensuring the stability and safety of intelligent driving. At the same time, when these functions are not enabled, the window heating function can be turned off to reduce energy consumption and balance energy efficiency with functional requirements.

[0050] In some embodiments, controlling the start / stop state of the window heating function based on the start / stop state of the preset intelligent driving function specifically includes:

[0051] Step A1: If the preset intelligent driving is in the off state, the vehicle turns off the window heating function;

[0052] Step A2: If the preset intelligent driving is in the activated state, the vehicle keeps the window heating function activated.

[0053] When the intelligent driving function is enabled, the vehicle can control the window heating function to remain enabled to ensure the clarity of the front camera in key scenes, thereby ensuring the stability of the vehicle's visual perception and improving the stability of the intelligent driving function. When the intelligent driving function is not enabled, the vehicle can turn off the window heating function to reduce unnecessary energy consumption, thereby achieving a balance between energy efficiency optimization and functional requirements and avoiding unnecessary power consumption.

[0054] In some embodiments, the turning on of the defrost function indicates that the front windshield is more likely to be frosted. In order to prevent the front windshield from fogging up again within a short period of time after the defrost function is turned off, thereby affecting the clarity of the front camera, the vehicle may perform the following steps:

[0055] Step B1: After determining that the defrost function is turned off, the vehicle turns off the window heating function after a preset time.

[0056] The formation of fog is usually closely related to temperature difference and humidity. When the defrost function is turned off, due to the large temperature difference between the windshield and the environment, moisture in the air is easy to condense on the front windshield in a short time. To avoid this situation, the vehicle controls the continuous operation of the window heating function within a preset time, which can keep the front camera window area at a constant temperature that is not easy to fog, thereby reducing the possibility of moisture condensation. The continuous operation of the window heating function can effectively reduce the temperature difference fluctuation in the front camera window area and inhibit the rapid condensation of moisture, thereby preventing the front windshield from fogging again in a short time, ensuring the clarity of the front camera and the stability of the vehicle's visual perception.

[0057] In this embodiment, by turning off the window heating function after a preset period of time, the influence of fog formation on the clarity of the front camera can be effectively delayed, preventing the front windshield from fogging up again in a short period of time, thereby ensuring the clarity of the front camera and the stability of the vehicle's visual perception.

[0058] In some embodiments, the most basic function of the vehicle is to provide transportation, which requires the vehicle to be able to start and drive normally. Compared with ensuring the stable operation of the preset intelligent driving functions, ensuring the normal operation of the basic functions of the vehicle is the most fundamental requirement. Based on this, the vehicle can also perform the following steps:

[0059] Step C1: When the voltage state of the vehicle is low and the battery power of the vehicle is less than a preset power, the vehicle turns off the window heating function.

[0060] When the vehicle is in a low voltage state and the battery charge is below the preset threshold, it means that the current energy reserve of the vehicle is insufficient and it may be difficult to support the normal operation of all power-consuming devices at the same time. In this case, the vehicle can prioritize the basic functions of the vehicle, such as starting, driving, and other functions directly related to safety. At this time, although the window heating function can improve the visual clarity of the front-view camera, its continuous operation will consume additional power. Therefore, in order to avoid the impact of low power on the operation of the core functions of the vehicle, the vehicle can turn off the window heating function and give priority to the limited power to the equipment that can ensure the basic operation and safety performance of the vehicle.

[0061] In this embodiment, when the vehicle's power reserve is insufficient, the window heating function can be turned off to ensure that the limited power is used to maintain the core functions of the vehicle, thereby improving the reliability of the vehicle's operation.

[0062] In some embodiments, in addition to being realized by a warm air system, air conditioning dehumidification and / or air circulation adjustment, the defrost function may also activate the heating function corresponding to each windshield. In particular, when the front windshield needs to be defrosted, it is usually accompanied by the activation of the front windshield heating function. Therefore, in the scenario where the window heating function is linked to the defrost function, the front windshield heating and window heating functions may be enabled at the same time. Because the first heating area of ​​the front windshield heating function overlaps with the second heating area of ​​the window heating function, the simultaneous activation of the front windshield heating and window heating functions will cause the second heating area to be heated by two heat sources at the same time. This not only easily leads to energy waste, but may also cause uneven temperature distribution of the front windshield, increase the risk of local overheating of the second heating area, and thus may cause damage to the windshield and the front-view camera.

[0063] To avoid this situation, the vehicle can perform the following steps:

[0064] Step D1: When the front windshield heating function of the vehicle is turned on, the vehicle turns off the window heating function.

[0065] Considering that the first heating area of ​​the front windshield heating function has covered the second heating area of ​​the window heating function, this function can not only meet the requirements of the front camera window clarity, but also undertake the task of providing heating for the entire windshield to ensure that the driver has a good field of vision and ensure driving safety. Therefore, when the front windshield heating function is turned on, the vehicle can automatically turn off the window heating function. At this time, the front camera window heating needs to pay attention to the status of the front windshield heating. When the front windshield heating is turned on, the window heating function is automatically turned off to avoid the two heating sources acting at the same time to cause local overtemperature, thereby preventing damage to the camera and glass, while optimizing energy consumption.

[0066] In this embodiment, the first heating area of ​​the front windshield heating function has covered the second heating area of ​​the window heating function. In order to meet the requirements of the front camera window clarity and avoid heating function redundancy, the vehicle can turn off the window heating function. This can not only prevent the local temperature from being too high and protect the front camera and glass from damage, but also reduce energy consumption while ensuring that the front windshield heating function meets the driver's higher vision clarity requirements.

[0067] In some embodiments, the defrost function includes a windshield defrost function. Given that the clarity of the front camera is mainly affected by the condition of the windshield, when the vehicle links the window heating function with the defrost function, it is mainly linked with the windshield defrost function. That is, when the windshield defrost function is activated, the vehicle then activates the window heating function to ensure that the window heating function can operate at the appropriate time, further improve its stability, and effectively ensure the clarity of the front camera.

[0068] In some embodiments, see Figure 2 , Figure 2 The following is a flow chart of a method for defogging a front-view camera of a vehicle in an actual application scenario. In this method, the vehicle mainly performs the following steps:

[0069] Step 210: Determine whether the front windshield defrost function is turned on.

[0070] Step 220: Activate the window heating function of the vehicle's front-view camera.

[0071] In order to improve the accuracy of the window heating start-up timing, the vehicle links the window heating function with the windshield defrost function based on the start-up advantage of the windshield defrost function, that is, the accurate and reliable start-up timing. That is, when the windshield defrost function is turned on, the vehicle actively turns on the window heating function, which can significantly improve the accuracy of the window heating start-up timing. In addition, since the fog or frost on the windshield usually spreads from the edge to the center, and the front camera window area is usually far away from the edge, the defrost function starts when the fog or frost on the windshield appears at the edge. The window heating function is linked with the defrost function, and can start the window heating function in advance before the fog or frost spreads to the field of view of the front camera, effectively reducing the impact of fog or frost on the camera, and further improving the stability of visual perception and the reliability of intelligent driving.

[0072] Step 230: Determine whether any preset intelligent driving function is turned on.

[0073] Step 240: turn off the window heating function.

[0074] Step 250: Determine whether the front windshield heating function is turned on.

[0075] Step 260: Determine whether the voltage state of the vehicle is low voltage and whether the battery power is less than a preset power.

[0076] Step 270: Determine whether the front windshield defrost function is turned off.

[0077] In order to balance the vehicle's energy consumption, after turning on the window heating function, the vehicle will make judgments in four aspects, namely, whether the preset driving function is enabled, whether the front windshield heating function is turned on, whether the vehicle's voltage status is low and the battery power is less than the preset power, and whether the front windshield defrost function is turned off. If any of the conditions for turning off the window heating function are met, the vehicle can turn off the window heating function to reduce vehicle energy consumption.

[0078] It can be understood that the four aspects of judgment can be performed in any order.

[0079] For example, Figure 2The execution sequence shown is a priority consideration from driving function requirements, functional redundancy, vehicle power status to environmental requirements. First, when the preset driving function is enabled, the clarity of the front camera is required to be high. Prioritizing its status can quickly determine whether to continue the window heating function; second, the front windshield heating function covers the window heating area and can meet the clarity requirements. If the front windshield heating is turned on, turning off the window heating can avoid functional conflicts and local overheating; then, although the low voltage state and low battery power are the most important, the probability of their occurrence is relatively low, so they are placed in the third place for judgment. If such an occasional situation occurs, the vehicle can also promptly ensure the basic driving function of the vehicle and turn off the window heating to reduce non-core energy consumption; finally, when the front windshield defrost function is turned on, there is a risk of continuous fogging or frost in the area, and the window heating function needs to continue to run to ensure a clear field of view of the front camera. Therefore, the window heating function is finally turned off only after the front windshield defrost function is turned off. This judgment sequence comprehensively considers the balance between vehicle energy efficiency optimization and functional requirements, gradually reduces the priority, and ensures the scientificity and rationality of the judgment logic.

[0080] Step 280, timing.

[0081] Step 290: Determine whether the timing reaches a preset duration.

[0082] Among them, when the defrost function is turned off, due to the large temperature difference between the front windshield and the environment, the moisture in the air is easy to condense into fog and adhere to the front windshield in a short time. To avoid this situation, the vehicle maintains the operation of the window heating function for a preset period of time, so that the front camera window area is stabilized at a temperature that is not easy to fog, thereby reducing the possibility of moisture condensation. The continuous operation of the window heating function can effectively reduce the temperature difference fluctuation in the front camera window area and inhibit the rapid condensation of moisture, thereby preventing the windshield from fogging again in a short time, ensuring the clarity of the front camera and the stability of the vehicle's visual perception.

[0083] In this embodiment, when the defrost function of the vehicle is activated, especially when the defrost function of the front windshield is activated, in order to cope with the high risk of fogging of the front windshield, ensure the clarity of the front camera and improve the stability of the intelligent driving function, the window heating function can be linked with the defrost function: when the defrost function is activated, the window heating function is automatically turned on. In order to further optimize energy consumption management, the window heating function can be dynamically adjusted in combination with the state of the intelligent driving function associated with the front camera to avoid unnecessary energy consumption when the intelligent driving function is not enabled. In addition, since there is a partial overlap between the window heating and the front windshield heating area, when the front windshield heating function is activated, the window heating function can be turned off to avoid resource waste and local overheating risks. When the vehicle voltage is in a low voltage state or the battery power is lower than the preset threshold, the window heating function can be turned off first to ensure the basic operation safety of the vehicle. Finally, when the defrost function of the front windshield is turned off, the window area can be prevented from fogging again in a short time by delaying the closure of the window heating function.

[0084] Combining the above embodiments, it can be seen that the defogging effect of the front camera is significantly improved through the linkage design of the window heating function and the defrosting function, as well as the dynamic coordination with the intelligent driving function status, the front windshield heating function and the vehicle energy consumption management. This multi-dimensional optimization strategy not only effectively avoids the front windshield from fogging again in a short period of time, but also prevents local overheating and waste of resources, ensures a clear field of view for the front camera, thereby ensuring the stability of the vehicle's intelligent driving function, while taking into account the rationality of energy consumption and the safety of the vehicle's basic operation.

[0085] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
