[0015] The specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present application is not limited by the specific implementation methods.

[0016] Unless explicitly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising”, etc., will be understood to include the stated elements or components but not to exclude other elements or components.

[0017] The technical solution of the embodiment of the present application can be applied to a smart driving camera, which is a camera installed on a vehicle. It can capture images of the vehicle's surroundings to assist in vehicle driving, or monitor whether there are any abnormalities in the surrounding environment.

[0018] It is understandable that vehicles may be driven in various environments. In some driving environments, the smart driving camera may overheat. Due to the overheating of the smart driving camera, the image quality collected by the smart driving camera may be poor, or it may not be able to operate stably, which may cause problems in vehicle driving. Therefore, it is necessary to provide overheat protection for the smart driving camera.

[0019] In the related art, it is usually determined whether there is an over-temperature situation based on the temperature data detected by the temperature sensor, and then the corresponding over-temperature protection strategy is executed. This over-temperature protection method considers too few over-temperature factors and cannot accurately determine whether there is an over-temperature situation; and the effect of the determined over-temperature protection strategy is also poor.

[0020] Based on this, the embodiment of the present application provides a technical solution, in which various factors are combined to achieve accurate judgment of over-temperature protection; thus, the determined over-temperature protection strategy has a better effect and can achieve effective over-temperature protection of the smart driving camera. In addition, the camera module is equipped with an encoder and a shock absorbing device, and the encoder can achieve image encoding that is more in line with the actual situation according to a more accurate over-temperature protection strategy; the shock absorbing device can achieve camera module shock absorption that is more in line with the actual situation according to a more accurate over-temperature protection strategy. Therefore, a more accurate over-temperature protection strategy can be combined to ensure the operating stability and safety of the camera module, thereby ensuring that the camera module can capture high-quality images.

[0021] Figure 1 is a structural block diagram of a vehicle system according to an embodiment of the present application, such as Figure 1 As shown, in the vehicle system, an intelligent driving camera over-temperature protection system and a vehicle control system are included, wherein the vehicle control system may include a vehicle driving system and a central control system, etc. The intelligent driving camera over-temperature protection system may be connected to the vehicle control system and transmit data or control instructions to each other.

[0022] Figure 2 is a structural block diagram of an over-temperature protection system for an intelligent driving camera according to an embodiment of the present application, such as Figure 2 As shown, the system includes: a camera module 21, a temperature sensor 22, a humidity sensor 23, an over-temperature protection device 24 and an over-temperature alarm 25.

[0023] In some embodiments, the camera module 21 includes at least two smart driving cameras, and the at least two smart driving cameras are respectively arranged at different positions of the vehicle. For example, the smart driving camera can be arranged on the top of the vehicle, the front of the vehicle, the bottom of the vehicle, and the side of the vehicle.

[0024] In some embodiments, the temperature sensor 22 is disposed in the camera module 21 to detect the temperature data of the camera module 21. It is understood that the temperature sensor 22 can be disposed inside the smart driving camera or around the smart driving camera, as long as the temperature data of the camera module 21 can be detected. It is understood that the temperature data may not be directly for the temperature of the smart driving camera, but may be the temperature of the environment surrounding the smart driving camera.

[0025] In some embodiments, the humidity sensor 23 is disposed in the camera module 21 to detect humidity data of the camera module 21. It is understood that the humidity sensor 23 can be disposed inside the smart driving camera or around the smart driving camera, as long as the humidity data of the camera module 21 can be detected. It is understood that the humidity data may not be directly for the humidity of the smart driving camera, but may be the humidity of the environment surrounding the smart driving camera.

[0026] In some embodiments, the number of temperature sensors 22 and the number of humidity sensors 23 may be the same as the number of smart driving cameras, or may be less than the number of smart driving cameras; it only needs to ensure that the corresponding temperature data or humidity data can be detected for each smart driving camera.

[0027] In some embodiments, the over-temperature protection device 24 is disposed in the camera module 21 for over-temperature protection of at least two smart driving cameras.

[0028] As an optional implementation, please refer to Figure 3 , is a structural block diagram of an over-temperature protection device 24 according to an embodiment of the present application, such as Figure 3 As shown, the over-temperature protection device 24 includes a high-temperature protection device 240, a low-temperature protection device 242 and a fault detection device 243. The high-temperature protection device 240 is used to perform high-temperature protection on at least two intelligent driving cameras, and the low-temperature protection device 242 is used to perform low-temperature protection on at least two intelligent driving cameras; the fault detection device 243 is used to detect whether there is a fault in the high-temperature protection device 240 and / or the low-temperature protection device 242. If a fault is detected in the high-temperature protection device 240 or the low-temperature protection device 242, fault reporting information is generated and reported to the over-temperature alarm 25; if a fault is detected in the high-temperature protection device 240 and the low-temperature protection device 242, fault reporting information is generated and reported to the control system of the vehicle.

[0029] In some embodiments, the high temperature protection device 240 can be, for example, a fan, a heat conducting component, a water cooling device, etc., which is a related device that can reduce the temperature of the smart driving camera. The number of the high temperature protection devices 240 can be the same as the number of smart driving cameras, that is, a corresponding high temperature protection device 240 is configured for each smart driving camera.

[0030] In some embodiments, the low temperature protection device 242 may be, for example, a heating element (heating plate, heating coil), etc., which is a related device that can increase the temperature of the smart driving camera. The number of the low temperature protection devices 242 may be the same as the number of smart driving cameras, that is, a corresponding low temperature protection device 242 is configured for each smart driving camera.

[0031] It can be understood that the specific structural design of the high temperature protection device 240 and the low temperature protection device 242 can refer to the mature technology in the field and will not be introduced in detail here.

[0032] In some embodiments, the over-temperature protection device 24 is further configured with a fault detection device 243 , which can detect whether the high-temperature protection device 240 and / or the low-temperature protection device 242 is faulty.

[0033] In some embodiments, different types of fault detection devices 243 may be configured in combination with different over-temperature protection devices 24. For example, for a high temperature protection device 240 such as a fan, it may detect whether the fan can operate normally, whether the wind force of the fan can be adjusted normally, etc., to determine whether the fan has a fault.

[0034] In some embodiments, if a fault is detected in the high temperature protection device 240 or the low temperature protection device 242, fault reporting information is generated and reported to the over-temperature alarm 25. In this embodiment, if only one of the two protection devices is faulty, the corresponding fault can be reported to the over-temperature alarm 25, so that the over-temperature alarm 25 can reasonably determine the over-temperature protection strategy.

[0035] In some embodiments, if a fault is detected in the high temperature protection device 240 and the low temperature protection device 242, fault reporting information is generated and reported to the control system of the vehicle. In this embodiment, since both protection devices are faulty, it means that the over-temperature protection cannot be performed normally. At this time, the fault can be directly reported to the control system of the vehicle so that the control system of the vehicle can issue a corresponding alarm prompt, so that the user can handle the fault to ensure the stable operation of the vehicle.

[0036] In some embodiments, the over-temperature alarm 25 is connected to the temperature sensor 22 and the humidity sensor 23 respectively, and is connected to the driving system of the vehicle. The over-temperature alarm 25 is used to determine the over-temperature protection strategy and execute the over-temperature protection strategy based on the temperature data of the camera module 21, the humidity data of the camera module 21, the driving data of the vehicle and the image data of the camera module 21; wherein the over-temperature protection strategy is used to control the over-temperature protection device 24 to perform over-temperature protection on the camera module 21.

[0037] Next, the implementation method of the over-temperature alarm device 25 determining the over-temperature protection strategy is introduced.

[0038] In some embodiments, the over-temperature protection device 24 can also be controlled according to user instructions (ie, manually controlled). In the embodiment of the present application, the over-temperature protection device 24 is mainly described as being intelligently controlled by the over-temperature alarm 25 .

[0039] In combination with the introduction of the foregoing embodiments, the temperature data of the camera module 21 may include temperature data corresponding to at least two smart driving cameras respectively, the humidity data of the camera module 21 may include humidity data corresponding to at least two smart driving cameras respectively, and the image data of the camera module 21 may include image data collected by at least two smart driving cameras respectively.

[0040] Then, the over-temperature alarm machine 25 is further used to: determine the over-temperature assessment results corresponding to the at least two intelligent driving cameras according to the temperature data corresponding to the at least two intelligent driving cameras, the humidity data corresponding to the at least two intelligent driving cameras, the image data collected by the at least two intelligent driving cameras and the driving data of the vehicle; determine the over-temperature assessment result of the camera module 21 according to the over-temperature assessment results corresponding to the at least two intelligent driving cameras and the setting positions of the at least two intelligent driving cameras; determine the over-temperature protection strategy according to the over-temperature assessment result of the camera module 21.

[0041] In this embodiment, the over-temperature assessment results corresponding to the at least two smart driving cameras are first determined based on the temperature data corresponding to the at least two smart driving cameras, the humidity data corresponding to the at least two smart driving cameras, the image data collected by the at least two smart driving cameras, and the driving data of the vehicle; and then the over-temperature assessment results corresponding to the at least two smart cameras and the setting positions of the at least two smart driving cameras are combined to determine the over-temperature assessment result of the entire camera module 21.

[0042] As an optional implementation, the over-temperature alarm 25 is further used to: for any smart driving camera, determine a first over-temperature assessment result of the smart driving camera based on the temperature data corresponding to the smart driving camera and the humidity data corresponding to the smart driving camera; determine a second over-temperature assessment result of the smart driving camera based on the image data collected by the smart driving camera; determine a third over-temperature assessment result of the smart driving camera based on the first over-temperature assessment result, the second over-temperature assessment result and the driving data of the vehicle; determine the over-temperature assessment result corresponding to the smart driving camera based on the third over-temperature assessment result.

[0043] In this embodiment, the first over-temperature assessment result is determined by combining the temperature data and humidity data of the intelligent driving camera; the second over-temperature assessment result is determined based on the image data collected by the intelligent driving camera; then, the third over-temperature assessment result is determined based on the two over-temperature assessment results and the driving data of the vehicle. Finally, the final over-temperature assessment result is determined based on the third over-temperature assessment result.

[0044] As an optional implementation, the temperature data corresponding to the smart driving camera includes temperature values ​​corresponding to multiple time points, and the humidity data corresponding to the smart driving camera includes humidity values ​​corresponding to multiple time points. In this implementation, both the temperature data and the humidity data can be data within a period of time, that is, whether there is overheating is not judged in real time, and it can be judged after each cycle. Moreover, real-time judgment cannot guarantee accuracy. Therefore, combining data within a period of time to determine the overheating assessment result has higher accuracy and rationality.

[0045] In some embodiments, the starting time point of the multiple time points may be a time point after the over-temperature protection strategy was last executed, and the ending time point may be the current time point.

[0046] Furthermore, the over-temperature alarm 25 is further used to: determine the average temperature value of the temperature values ​​corresponding to multiple time points; determine the average humidity value of the humidity values ​​corresponding to multiple time points; if the average temperature value is greater than the first preset temperature value, and the average humidity value is less than the first preset humidity value, determine that the first over-temperature evaluation result of the intelligent driving camera is that the intelligent driving camera is in a high temperature environment; if the average temperature value is less than the second preset temperature value, and the average humidity value is greater than the second preset humidity value, determine that the first over-temperature evaluation result of the intelligent driving camera is that the intelligent driving camera is in a low temperature environment, the second preset temperature value is less than the first preset temperature value, and the second preset humidity value is greater than the first preset humidity value.

[0047] In some embodiments, the first preset temperature value may be the highest temperature value that the smart driving camera can withstand, and the first preset humidity value may be the lowest humidity value when the air is in a high temperature condition. The second preset temperature value may be the lowest temperature value that the smart driving camera can withstand, and the second preset humidity value may be the lowest humidity value at which the smart driving camera will not fog.

[0048] Further, if the average temperature value and the average humidity value do not meet the above conditions, it is determined that the first over-temperature evaluation result is that the smart driving camera is not in an over-temperature environment.

[0049] In some embodiments, based on the image data collected by the smart driving camera, it is possible to determine whether the smart driving camera is in an over-temperature environment according to a preset evaluation model. The training data of the preset evaluation model may include multiple images, including images collected by the smart driving camera in a high temperature environment (setting a high temperature environment label), and also including images collected by the smart driving camera in a low temperature environment (setting a low temperature environment label). The evaluation model is trained according to the training data, so that the evaluation model determines whether the smart driving camera is in an over-temperature environment according to the currently collected image data.

[0050] Therefore, based on the image data collected by the smart driving camera, the second over-temperature assessment result of the smart driving camera can be determined.

[0051] Furthermore, the third over-temperature assessment result of the intelligent driving camera is determined in combination with the first over-temperature assessment result, the second over-temperature assessment result and the driving data of the vehicle.

[0052] As an optional implementation, the first over-temperature evaluation result and the second over-temperature evaluation result are both used to characterize whether the smart driving camera is in a high temperature environment or a low temperature environment, and the driving data of the vehicle includes: the driving state of the vehicle within a preset time period, and the over-temperature alarm 25 is further used to: if the first over-temperature evaluation result and the second over-temperature evaluation result both characterize that the smart driving camera is in a high temperature environment, and the driving state of the vehicle within the preset time period includes at least two driving states, determine that the smart driving camera is in a high temperature environment requiring over-temperature protection; if the first over-temperature evaluation result or the second over-temperature evaluation result characterizes that the smart driving camera is in a high temperature environment, And the driving state of the vehicle within the preset time is the same driving state, it is determined that the intelligent driving camera is in a high temperature environment requiring over-temperature protection; if the first over-temperature assessment result and the second over-temperature assessment result both indicate that the intelligent driving camera is in a low temperature environment, and the driving state of the vehicle within the preset time is to maintain the target driving state, it is determined that the intelligent driving camera is in a low temperature environment requiring over-temperature protection; if the first over-temperature assessment result or the second over-temperature assessment result indicates that the intelligent driving camera is in a low temperature environment, and the driving state of the vehicle within the preset time includes at least two driving states, it is determined that the intelligent driving camera is in a low temperature environment requiring over-temperature protection.

[0053] In this embodiment, the preset duration may be consistent with the duration formed by the aforementioned multiple time points. Combining the two over-temperature evaluation results, when the aforementioned four conditions are met, the smart driving camera may be considered to be in an over-temperature environment, and it may be determined whether it is in a high temperature environment or a low temperature environment.

[0054] In the first case, the two over-temperature evaluation results are consistent, both are high-temperature environments, and at least two driving states, proving that the vehicle's driving environment is relatively complex. At this point, it can be determined that the smart driving camera is in a high-temperature environment that requires over-temperature protection.

[0055] In the second case, only one of the two over-temperature assessment results indicates that the smart driving camera is in a high-temperature environment, and the vehicle's driving state is the same within a preset time period, indicating that the vehicle may be in the same driving environment for a long time. At this time, it can also be determined that the smart driving camera is in a high-temperature environment that requires over-temperature protection.

[0056] In the third case, both over-temperature evaluation results indicate that the smart driving camera is in a low-temperature environment, and the vehicle's driving state within the preset time is to maintain the target driving state. At this time, it means that the vehicle may be in the target driving environment for a long time. At this time, it can be determined that the smart driving camera is in a low-temperature environment that requires over-temperature protection. The target environment can be special weather such as snowy days and rainy days. Therefore, the target driving state can be a relatively low-speed driving state, and the window cleaner is always kept in working state.

[0057] In the fourth case, only one of the two over-temperature assessment results indicates that the smart driving camera is in a low-temperature environment, and the vehicle's driving state within a preset time period includes at least two driving states, indicating that the vehicle may have driven from a normal environment into a low-temperature environment. It can be determined that the smart driving camera is in a low-temperature environment that requires over-temperature protection.

[0058] Furthermore, the third over-temperature assessment result can be directly determined as the over-temperature assessment result corresponding to the smart driving camera. Alternatively, the third over-temperature assessment result is fed back to the vehicle computer end, and after confirmation by the user of the vehicle computer end, the confirmed over-temperature assessment result is determined as the final over-temperature assessment result.

[0059] Therefore, according to the above-mentioned method of determining the over-temperature assessment result, the over-temperature assessment results corresponding to at least two smart driving cameras can be determined respectively, and through integration, the over-temperature assessment result of the entire camera module 21 can be determined.

[0060] As an optional implementation, the over-temperature assessment results corresponding to at least two smart driving cameras are respectively used to characterize whether the smart driving cameras are in a high temperature environment or a low temperature environment requiring over-temperature protection, and the over-temperature alarm 25 is further used to: if the number of first target over-temperature assessment results in the over-temperature assessment results corresponding to at least two smart driving cameras is greater than a preset number, and the setting position of the smart driving camera corresponding to the first target over-temperature result meets the first setting position condition, it is determined that the over-temperature assessment result of the camera module 21 is that the camera module 21 is in a high temperature environment requiring over-temperature protection; wherein, the first target over-temperature assessment result is in a high temperature environment requiring In a high temperature environment for over-temperature protection, the first setting position condition is: multiple smart driving cameras are respectively set in different directions of the vehicle; if the number of second target over-temperature assessment results in the over-temperature assessment results corresponding to at least two smart driving cameras is greater than a preset number, and the setting positions of the smart driving cameras corresponding to the second target over-temperature results meet the second setting position condition, it is determined that the over-temperature assessment result of the camera module 21 is that the camera module 21 is in a low temperature environment requiring over-temperature protection; wherein, the second target over-temperature assessment result is in a low temperature environment requiring over-temperature protection, and the second setting position condition is: multiple smart driving cameras are set in the target direction of the vehicle.

[0061] It is understandable that since the camera module 21 includes multiple smart driving cameras, if only one smart driving camera is in an over-temperature environment, over-temperature protection may not be required. Therefore, it is necessary to determine the over-temperature evaluation result of the camera module 21 as a whole to achieve over-temperature protection with lower energy consumption.

[0062] In this embodiment, the preset number may be half of the number of the at least two smart driving cameras.

[0063] In the first case, since the smart driving cameras that require high temperature protection are set in different directions of the vehicle, it means that the entire camera module 21 is in a high temperature environment that requires over-temperature protection.

[0064] In the second case, the target direction may be the direction in which the driving camera required for vehicle driving is set. For example, the camera in front of the vehicle. Since the intelligent driving camera that requires low temperature protection is set in the target direction of the vehicle, it means that the situation at this time is relatively bad, and it can be regarded that the entire camera module 21 is in a low temperature environment that requires over-temperature protection.

[0065] For some other situations, it can be considered that the entire camera module 21 does not need over-temperature protection, but some of the smart driving cameras may need over-temperature protection.

[0066] Furthermore, as an optional implementation, the over-temperature assessment result of the camera module 21 is used to characterize whether the camera module 21 is in a high temperature environment or a low temperature environment requiring over-temperature protection, and the over-temperature protection device 24 includes at least two over-temperature protection devices 24 corresponding to each of the two smart driving cameras.

[0067] Thus, the over-temperature alarm 25 is further used for: if the camera module 21 is in a high-temperature environment requiring over-temperature protection, the over-temperature protection strategy is determined as: controlling the over-temperature protection devices 24 corresponding to at least two smart driving cameras respectively, and performing high-temperature protection on at least two smart driving cameras respectively; if the camera module 21 is in a low-temperature environment requiring over-temperature protection, the over-temperature protection strategy is determined as: controlling the target over-temperature protection device 24 corresponding to the target smart driving camera, and performing low-temperature protection on the target smart driving camera, the usage frequency of the target driving camera is greater than the preset usage frequency, and the accuracy of the target driving camera is higher than the preset accuracy.

[0068] In this embodiment, if the camera module 21 is in a low temperature environment requiring over-temperature protection, it can be understood based on the aforementioned judgment conditions that not all cameras are in a low temperature environment requiring over-temperature protection, so only the target smart driving camera can be protected from low temperature.

[0069] Furthermore, since the usage frequency of the smart driving camera in the target direction is definitely greater than the preset usage frequency, the low temperature protection effect of the high-precision smart driving camera in the target direction can be achieved. Other smart driving cameras can also be protected from low temperatures if they meet these two conditions.

[0070] In some embodiments, the preset usage frequency and preset accuracy can be set according to the configuration of the smart driving camera of different vehicles, and are not limited here.

[0071] In some embodiments, the over-temperature protection strategy may be, for example: turning on a fan to blow air for a period of time; turning on a heating plate to heat for a period of time; turning on a heat-conducting element to conduct heat for a period of time, etc.

[0072] In some embodiments, the over-temperature alarm 25 generates a control instruction for the over-temperature protection device 24 according to the over-temperature protection strategy, and then sends it to the over-temperature protection device 24 to implement over-temperature protection control.

[0073] In some embodiments, the over-temperature alarm device 25 can also perform an over-temperature alarm. For example, if the camera module 21 needs over-temperature protection, an alarm message can be sent to the vehicle computer.

[0074] Through the introduction of the embodiment of the present application, it can be seen that by configuring the temperature sensor 22 to detect temperature data and the humidity sensor 23 to detect humidity data, and then combining the driving data of the vehicle and the image data of the camera module 21, the over-temperature protection strategy is determined; and then the over-temperature protection device 24 is controlled according to the over-temperature protection strategy to perform over-temperature protection on the camera module 21. This over-temperature protection method combines many factors to achieve accurate judgment of over-temperature protection; thus, the determined over-temperature protection strategy has a better effect and can achieve effective over-temperature protection of the smart driving camera.

[0075] In an embodiment of the present application, a camera module 21 is also provided, which can be used as a camera module 21 in an over-temperature protection system of an intelligent driving camera.

[0076] Please refer to Figure 4 , is a structural block diagram of a first camera module 21 according to an embodiment of the present application, such as Figure 4 As shown, the camera module 21 includes: at least two smart driving cameras 210, an encoder 212 and a shock absorbing device 214.

[0077] It can be understood that the camera module 21 includes Figure 4 The components shown also include other more basic components.

[0078] In some embodiments, the appearance and structural design of the camera module 21 can have different implementation methods according to different application scenarios, which are not limited in the embodiments of the present application.

[0079] In some embodiments, at least two smart driving cameras 210 are respectively arranged at different positions of the vehicle, and the specific implementation methods can refer to the aforementioned embodiments.

[0080] In some embodiments, the encoder 212 is respectively connected to at least two smart driving cameras 210, and to the over-temperature alarm 25.
