Description

Technical Field

[0001] The present application relates to the field of electronic equipment protection, and in particular to an electronic equipment protection method and protection system. Background Art

[0002] With the popularity of electronic devices, users frequently use portable electronic devices such as smartphones and tablets in their daily lives. However, these devices are often left behind in parked vehicles, especially in the hot summer environment, when the temperature inside the car can quickly rise to over 60 degrees Celsius. This extreme high temperature environment can cause the temperature of the built-in batteries of electronic devices to rise sharply, causing rapid battery expansion, and may even cause safety hazards such as battery leakage, fire or explosion.

[0003] In the related art, electronic devices are usually protected by a high-temperature automatic shutdown mechanism. When it is detected that the internal temperature of the device exceeds the preset threshold, the system will automatically shut down the device to prevent the temperature from rising further. However, this mechanism has obvious limitations. First, although shutdown can reduce the discharge and charging activities of the battery, it cannot significantly reduce the storage energy of the battery. In a high-temperature environment, even if the device is turned off, chemical reactions inside the battery may still occur, causing the battery to continue to expand. Secondly, if the device cannot effectively dissipate heat after being shut down, the battery temperature may continue to rise, thereby increasing safety hazards. Therefore, the existing high-temperature automatic shutdown mechanism cannot effectively solve the safety problem of built-in batteries of electronic devices in high-temperature environments. In order to improve the safety of electronic devices in high-temperature environments, a new solution is urgently needed. Summary of the invention

[0035] Various aspects and features of the present application are described herein with reference to the accompanying drawings.

[0036] It should be understood that various modifications may be made to the embodiments of the present application. Therefore, the above description should not be considered as limiting, but only as an example of an embodiment. Other modifications within the scope and spirit of the present application will occur to those skilled in the art.

[0037] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the present application and, together with the general description of the present application given above and the detailed description of the embodiments given below, serve to explain the principles of the present application.

[0038] These and other characteristics of the present application will become apparent from the following description of a preferred form of embodiment given as a non-limiting example with reference to the accompanying drawings.

[0039] It should also be understood that although the present application has been described with reference to some specific examples, those skilled in the art will be able to readily implement many other equivalent forms of the present application.

[0040] The above and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.

[0041] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present application. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0042] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0043] An electronic device protection method of an embodiment of the present application can be used to protect electronic devices in a high-temperature closed environment. A high-temperature closed environment usually causes the temperature of the battery in the electronic device to rise rapidly. Excessive temperature will accelerate the chemical reaction inside the battery and generate too much heat, thereby increasing the risk of battery damage. In addition, even if the electronic device is turned off, the energy in the battery still exists. If this energy is released under extreme conditions, such as a short circuit caused by overheating, it may also cause serious consequences. The electronic device protection method of an embodiment of the present application controls the electronic device to perform corresponding tasks in a determined discharge mode, consumes the energy in the battery, so as to reduce the total amount of energy stored in the battery in the current state, that is, reduce the total amount of energy immediately available in the battery of the electronic device, thereby reducing the energy that may be released by the battery in extreme conditions (such as thermal runaway), reducing potential hazards, and achieving protection of the electronic device.

[0044] The electronic device protection method of the present application is described in detail below with reference to the accompanying drawings. Figure 1 This is a flow chart of the electronic device protection method according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0045] S100 , in response to the detected current environmental characteristics meeting a preset condition, determining a discharge mode of the electronic device.

[0046] In an embodiment of the present application, when an electronic device is in a high-temperature enclosed environment, the environmental characteristics will have a significant impact on the performance and life of the electronic device. In a high-temperature enclosed space, heat is not easy to dissipate, which will cause the temperature of the electronic device to continue to rise. In order to protect electronic devices in a high-temperature enclosed environment, it is necessary to comprehensively consider the impact of the environment on the performance of the electronic device and the characteristics of different discharge modes. By detecting the current environmental characteristics and comparing them with the preset conditions, the discharge mode of the electronic device is determined according to the comparison results, thereby reducing the storage energy of the built-in battery of the electronic device, which can improve the safety of the electronic device.

[0047] S200. Based on the determined discharge mode, control the electronic device to perform a corresponding task so that the battery of the electronic device reduces the first storage energy to the second storage energy, wherein the safety of the electronic device when the battery has the second storage energy is higher than the safety of the battery when the battery has the first storage energy.

[0048] It should be noted that in the embodiments of the present application, safety refers to the risk of failure or dangerous events (such as overheating, explosion, etc.) of the battery of the electronic device in a high-temperature and closed environment when storing different energies. In a certain discharge mode, controlling the electronic device to perform the corresponding discharge task can reduce the energy currently stored in the battery of the electronic device, that is, the battery can be reduced from a high storage energy state to a low storage energy state.

[0049] It is understandable that in a high-temperature, enclosed environment, the less energy currently stored in the battery of an electronic device, the lower the risk of a malfunction or dangerous event, and the higher the safety. For example, the electronic device has a first stored energy before performing a corresponding discharge task, and the stored energy decreases after performing the corresponding discharge task, and has a second stored energy at this time. The safety of the electronic device when the battery has the second stored energy is higher than the safety of the battery when the battery has the first stored energy.

[0050] In one embodiment, in the above step S100, the current environmental characteristics satisfying the preset condition includes: the temperature rise rate of the current environmental characteristics is greater than a preset temperature rise rate threshold.

[0051] By using the preset temperature rise rate threshold as a benchmark, the detected temperature rise rate of the current environmental characteristics is compared with the preset temperature rise rate threshold to determine whether the electronic equipment has an abnormal temperature rise. If the temperature rise rate of the current environmental characteristics exceeds the preset temperature rise rate threshold, it means that the electronic equipment is at risk of overheating and protection measures need to be initiated for the electronic equipment.

[0052] For example, if the preset temperature rise rate is 25℃~30℃ in 20 minutes, the temperature rise rate threshold is 1.25℃ / min~1.5℃ / min. If the actual measurement shows that it only takes 10 minutes for the temperature to rise to the same level, the actual temperature rise rate becomes 2.5℃ / min~3℃ / min. This indicates that the actual temperature rise rate is significantly higher than the preset temperature rise rate threshold, which means that the electronic equipment is at risk of overheating.

[0053] For the preset temperature rise rate threshold, a first preset temperature rise rate threshold and a second preset temperature rise rate threshold may be set, wherein the first preset temperature rise rate threshold is less than the second preset temperature rise rate threshold. When the detected temperature rise rate is greater than the first preset temperature rise rate threshold, it is determined that the electronic device has a first discharge mode; when the detected temperature rise rate is greater than the second preset temperature rise rate threshold, it is determined that the electronic device has a second discharge mode, wherein the discharge efficiency of the second discharge mode is greater than the discharge efficiency of the first discharge mode.

[0054] That is to say, the faster the temperature rise rate of the electronic device, the worse the current environment or working conditions are for the electronic device. In order to protect the electronic device from damage, the electronic device needs to discharge in a discharge mode with greater discharge efficiency to quickly reduce the load on the electronic device battery, thereby reducing the heat source.

[0055] In addition, to ensure the accuracy of the detected temperature rise rate of the current environmental characteristics, the temperature rise rate of the current environmental characteristics can be detected after the electronic device is in a static and standby state for a preset time. The standby state of the electronic device can be determined by whether the electronic device has an input event, and the static state of the electronic device can be determined by whether the electronic device has displacement and rotation.

[0056] In one embodiment, in the above step S100, Figure 2 This is a flow chart of determining the discharge mode of an electronic device in the electronic device protection method of an embodiment of the present application, such as Figure 2 As shown, determining the discharge mode of the electronic device includes:

[0057] S110: Determine the current physical state of the electronic device, where the physical state includes one or more of the following: placement posture, shielding state, and whether an external electrical device is connected.

[0058] In a high temperature and closed environment, for example, in a car parked under the scorching sun, the physical state of the electronic device will directly affect its discharge mode. In the embodiment of the present application, the physical state of the electronic device may include the placement posture, shielding state and whether an external power device is connected to the electronic device.

[0059] The placement of electronic devices may include a flat position and a vertical position. For example, electronic devices such as mobile phones, tablet computers or portable navigation devices are placed randomly somewhere in the car. If an electronic device is placed flat on the dashboard or on a seat, it may be directly exposed to sunlight, causing the surface temperature to rise rapidly. Placing it upright on a special stand or against a seat will slightly reduce the impact of direct light, but there is still a risk of heat accumulation.

[0060] Specifically, Figure 3 As shown, the placement posture of the electronic device can be identified through the following process:

[0061] S1110, using an accelerometer in the electronic device to obtain acceleration information of the electronic device; using a gyroscope in the electronic device to obtain rotation information of the electronic device.

[0062] S1120: Fuse the acceleration information and the rotation information to obtain fused data.

[0063] S1130. Calculate the pitch angle, roll angle, and yaw angle of the electronic device using the fused data.

[0064] S1140: Identify the current placement state of the electronic device according to the pitch angle, the roll angle, and the yaw angle.

[0065] The shielding posture of the electronic device may be that a certain side of the electronic device is shielded, or the electronic device is placed in an airtight protective cover or bag, and the entire electronic device is shielded, resulting in heat accumulation and temperature rise of the electronic device.

[0066] The external power-consuming devices connected to the electronic device may be high-power consuming devices such as external hard disks and USB fans.

[0067] S120: Determine a discharge mode of the electronic device based on the physical state of the electronic device.

[0068] In an embodiment of the present application, when the electronic device is connected to an external power-consuming device, the discharge mode of the electronic device is determined to be a third discharge mode, wherein when the electronic device is in the third discharge mode, the electronic device supplies power to the external power-consuming device to perform corresponding tasks, so that the battery of the electronic device is reduced from the first storage energy to the second storage energy.

[0069] That is to say, when the electronic device is connected to an external power-consuming device, the third discharge mode can be a power consumption mode of the external power-consuming device. By preferentially selecting this power consumption mode, the energy stored in the battery of the electronic device can be reduced, so that the battery of the electronic device is reduced from the first storage energy to the second storage energy.

[0070] In another embodiment, when the electronic device is not connected to an external power-consuming device or cannot be discharged through the external power-consuming device due to reasons such as the external power-consuming device being turned off, the discharge can be performed through components inside the electronic device.

[0071] When discharging through components inside the electronic device, determining a discharge mode of the electronic device based on a physical state of the electronic device may include:

[0072] When the electronic device is at an angle that satisfies the flat posture, the discharge mode of the electronic device is determined to be the fourth discharge mode; when the electronic device is at an angle that satisfies the upright posture, the discharge mode of the electronic device is determined to be the fifth discharge mode; wherein the number of components used by the electronic device to control the electronic device to perform a discharge task in the fourth discharge mode is less than the number of components used by the electronic device to control the electronic device to perform a discharge task in the fifth discharge mode.

[0073] Specifically, the placement posture of the electronic device can be determined by detecting the angle between the electronic device and the support. For example, the angle of the electronic device's horizontal placement posture can be set to 0° to 30°, and the angle of the electronic device's vertical placement posture can be set to 30° to 150°. Of course, other range values ​​can also be set according to actual needs. According to the angle of the horizontal placement posture or the angle of the vertical placement posture satisfied by the angle between the electronic device and the support, it can be determined that the electronic device is in a horizontal placement posture or a vertical placement posture.

[0074] When the electronic device is in a flat position, for example, when it is placed flat on a seat, the front or back of the electronic device is in contact with the seat, and the electronic device is partially blocked, which can easily cause the temperature of the electronic device to rise. When the electronic device is in a standing position, for example, when it is placed upright on a stand, the electronic device is less blocked. In these two placement positions, in order to prevent the temperature of the electronic device from rising too quickly, the number of internal components used for discharge in the discharge mode of the electronic device in the flat position is less than the number of internal components used for discharge in the discharge mode of the standing position.

[0075] Exemplarily, when the electronic device is in a flat position, in the fourth discharge mode, the components used to control the electronic device to perform the discharge task may be the processor and the display screen; when the electronic device is in a vertical position, in the fifth discharge mode, the components used to control the electronic device to perform the discharge task may be the processor, the display screen, the camera, the speaker, and the vibration motor. When the electronic device is in a flat position, by reducing the number of components used to perform the discharge task, the electronic device can be prevented from overheating while consuming the battery energy of the electronic device.

[0076] In other embodiments, when discharging is performed through components inside the electronic device, determining the discharge mode of the electronic device based on the physical state of the electronic device may further include:

[0077] When the electronic device is in a flat position and in a front-shielded state, for example, the electronic device is placed upside down on a seat with the display screen facing downward, the discharge mode of the electronic device is determined to be the sixth discharge mode; when the electronic device is in a flat position and in a back-shielded state, for example, the electronic device is placed upright on a seat with the display screen facing upward, the discharge mode of the electronic device is determined to be the seventh discharge mode. The sixth discharge mode includes controlling the rear camera of the electronic device to perform a shooting task at a rate higher than the first frame rate, and the seventh discharge mode includes controlling the display screen of the electronic device to perform a playback task at a rate higher than the first refresh rate.

[0078] It is understandable that when the electronic device is in a flat posture and in a front-blocking state, the display screen on the front of the electronic device is blocked. In the sixth discharge mode of the determined electronic device, the display screen may not work, and the energy stored in the battery of the electronic device is consumed by controlling the rear camera to perform a shooting task. In order to consume the energy stored in the battery relatively efficiently, the rear camera of the electronic device may be controlled to perform the shooting task at a rate higher than the first frame rate. The first frame rate may be understood as a default / standard frame rate. In other words, the rear camera is controlled to work at a higher frame rate level than when it is working normally.

[0079] For example, the default / standard frame rate used by a smartphone or tablet under normal circumstances is 30fps (frames per second). When the smartphone or tablet is in a flat position and the front is blocked, the rear camera of the smartphone or tablet can be controlled to perform shooting tasks at a frame rate of 60fps, 90fps, or 120fps, or even higher. High frame rate shooting can increase the workload of the processor in the smartphone or tablet and consume battery energy faster.

[0080] It is understandable that when the electronic device is in a flat posture and in a back-blocking state, the camera on the back of the electronic device is blocked. In the seventh discharge mode of the determined electronic device, the rear camera may not work, and the energy stored in the battery of the electronic device is consumed by controlling the display screen to perform the playback task. In order to consume the energy stored in the battery relatively efficiently, the display screen of the electronic device may be controlled to perform the display task at a rate higher than the first refresh rate. Among them, the first refresh rate can be understood as the default / standard refresh rate. In other words, the display screen is controlled to work at a higher refresh rate level than when it is working normally.

[0081] For example, the default / standard refresh rate of the display screen under normal circumstances is 60Hz. When the smartphone or tablet is in a flat posture and the back is blocked, the display screen of the smartphone or tablet can be controlled to perform display tasks at a refresh rate of 90Hz, 120Hz or 144Hz, or even a higher refresh rate. High refresh rate display can increase the workload of the processor in the smartphone or tablet and consume battery energy faster.

[0082] The above embodiments are only described by taking the display screen and the rear camera as examples. The front camera, speaker and flash of the electronic device can be controlled according to actual needs to perform corresponding tasks at a rate higher than the default / standard frame rate or frequency.

[0083] In addition, according to the heat source distribution of each component in the electronic device when it is working normally, the unobstructed components can be controlled to perform corresponding tasks to consume battery energy.

[0084] In the above embodiment, an application may also be set in the electronic device. When it is monitored that the electronic device is controlled to perform a corresponding task based on a determined discharge mode, the application may send an early warning to the user via text message, phone call or push notification to promptly remind the user to take necessary protective measures.

[0085] In the above embodiment, determining the shielding state of the electronic device includes at least one of the following: starting a camera of the electronic device, and determining whether the electronic device is in a front shielding state or a back shielding state based on a current first environment image captured by the camera;

[0086] A current second environment image captured by a vehicle-mounted camera device is acquired, wherein the current second environment image includes the electronic device, and based on the current environment image, it is determined whether the electronic device is in a front-side blocking state or a back-side blocking state.

[0087] In the embodiment of the present application, the camera device of the electronic device may include a front camera and a rear camera, and the first environment image captured by the front camera and / or the rear camera can be used to detect whether the front and / or the back of the electronic device is blocked. The captured first environment image can be preprocessed, feature extracted and analyzed, and then it can be determined whether there is an obstruction based on the analysis result.

[0088] For example, if the image analysis of the front camera and / or the rear camera shows that there is an object with low resolution and occupying most of the screen, it can be determined that the front and / or back is blocked. It should be noted that based on the working principle of the camera, extremely close objects may exceed its focal range, causing the object to appear blurred in the image. In addition, a very close object will block the view behind the camera, making the background information almost invisible or completely invisible.

[0089] In an embodiment of the present application, a camera device (such as a vehicle-mounted camera device) in the environment where the electronic device is located can be used to capture an image of the current second environment including the electronic device, and the captured second environment image can be preprocessed, feature extracted, and matched to determine whether there are any obstructions based on the matching results.

[0090] In other embodiments, Figure 4 and Figure 5 As shown, the electronic device protection method provided in the embodiment of the present application also includes:

[0091] S300, when the electronic device is controlled to perform a corresponding task based on the determined discharge mode, if the temperature of the battery reaches a safe value or the power of the battery reaches a target power, the electronic device is controlled to be turned off; or,

[0092] S400: When controlling the electronic device to perform a corresponding task based on the determined discharge mode, if the use state of the electronic device changes, controlling the electronic device to resume a normal working mode.

[0093] When the battery temperature is too high, continued use may cause the chemical substances inside the battery to decompose, shorten the battery life, or even cause safety issues such as swelling, leakage, or explosion. When controlling electronic devices to perform corresponding tasks based on a determined discharge mode, if the battery temperature reaches a safe value, the electronic devices are shut down first, thereby effectively avoiding potential risks.

[0094] In addition, when the electronic device is controlled to perform the corresponding task based on the determined discharge mode, if the battery power is too low (for example, less than 5%), continuous discharge may cause permanent damage to the battery. To avoid excessive discharge of the battery, by setting a target power level (i.e., a reasonable minimum power threshold) and controlling the electronic device to shut down when the value is reached, permanent damage to the battery can be prevented.

[0095] It can be understood that when an electronic device is controlled to perform a corresponding task based on a determined discharge mode, if the usage state of the electronic device changes, for example, the placement posture changes, the occlusion state changes, or there is input time, etc., then controlling the electronic device to resume normal working mode can ensure the immediate response of the electronic device and improve user satisfaction; in addition, once the adverse conditions are removed, the electronic device immediately resumes normal operation, which can ensure the continuity and reliability of the service and enhance the safety of the electronic device.

[0096] Based on the same inventive concept, Figure 6 As shown, the embodiment of the present application also provides an electronic equipment protection system, including:

[0097] The sensor 10 is used to detect current environmental characteristics.

[0098] The processor 20 determines a discharge mode of the electronic device based on the detected current environmental characteristics satisfying a preset condition;

[0099] Based on the determined discharge mode, the electronic device is controlled to perform a corresponding task so that the battery of the electronic device is reduced from a first storage energy to a second storage energy, wherein the safety of the electronic device when the battery has the second storage energy is higher than the safety of the battery when the battery has the first storage energy.

[0100] In an embodiment of the present application, the processor is also used to determine the current physical state of the electronic device, and the physical state includes one or more of the following: placement posture, shielding state, and whether an external electrical device is connected; determine the discharge mode of the electronic device based on the physical state of the electronic device.

[0101] In the embodiments of the present application, the placement posture of the electronic device may include a flat posture and a vertical posture. The shielding posture of the electronic device may be that a certain side of the electronic device is shielded, or the electronic device is placed in an airtight protective cover or bag, and the electronic device is completely shielded. The external power-consuming device connected to the electronic device may be a high-power consumption device such as an external hard disk and a USB fan.

[0102] In one embodiment, determining a discharge mode of the electronic device based on a physical state of the electronic device includes:

[0103] When the electronic device is connected to an external power-consuming device, the discharge mode of the electronic device is determined to be a third discharge mode, wherein when the electronic device is in the third discharge mode, the electronic device supplies power to the external power-consuming device to perform a corresponding task, so that the battery of the electronic device is reduced from the first storage energy to the second storage energy.

[0104] In another embodiment, when the electronic device is not connected to an external power-consuming device or cannot be discharged through the external power-consuming device due to reasons such as the external power-consuming device being turned off, the discharge can be performed through components inside the electronic device.

[0105] When discharging through components inside the electronic device, determining a discharge mode of the electronic device based on a physical state of the electronic device may include:

[0106] When the electronic device is at an angle that satisfies the flat posture, the discharge mode of the electronic device is determined to be the fourth discharge mode; when the electronic device is at an angle that satisfies the upright posture, the discharge mode of the electronic device is determined to be the fifth discharge mode; wherein the number of components used by the electronic device to control the electronic device to perform a discharge task in the fourth discharge mode is less than the number of components used by the electronic device to control the electronic device to perform a discharge task in the fifth discharge mode.

[0107] Specifically, the placement posture of the electronic device can be determined by detecting the angle between the electronic device and the support. For example, the angle of the electronic device's horizontal placement posture can be set to 0° to 30°, and the angle of the electronic device's vertical placement posture can be set to 30° to 150°. Of course, other range values ​​can also be set according to actual needs. According to the angle of the horizontal placement posture or the angle of the vertical placement posture satisfied by the angle between the electronic device and the support, it can be determined that the electronic device is in a horizontal placement posture or a vertical placement posture.

[0108] When the electronic device is in a flat position, for example, when it is placed flat on a seat, the front or back of the electronic device is in contact with the seat, and the electronic device is partially blocked, which can easily cause the temperature of the electronic device to rise. When the electronic device is in a standing position, for example, when it is placed upright on a stand, the electronic device is less blocked. In these two placement positions, in order to prevent the temperature of the electronic device from rising too quickly, the number of internal components used for discharge in the discharge mode of the electronic device in the flat position is less than the number of internal components used for discharge in the discharge mode of the standing position.

[0109] In other embodiments, when discharging is performed through components inside the electronic device, determining the discharge mode of the electronic device based on the physical state of the electronic device may further include:

[0110] When the electronic device is in a flat position and in a front-shielded state, for example, the electronic device is placed upside down on a seat with the display screen facing downward, the discharge mode of the electronic device is determined to be the sixth discharge mode; when the electronic device is in a flat position and in a back-shielded state, for example, the electronic device is placed upright on a seat with the display screen facing upward, the discharge mode of the electronic device is determined to be the seventh discharge mode. The sixth discharge mode includes controlling the rear camera of the electronic device to perform a shooting task at a rate higher than the first frame rate, and the seventh discharge mode includes controlling the display screen of the electronic device to perform a playback task at a rate higher than the first refresh rate.

[0111] In the above embodiment, the electronic device protection system can protect tablet computers, laptop computers, or smart phones in a high-temperature closed environment. An application is set in electronic devices such as tablet computers, laptop computers, or smart phones. When it is detected that the electronic device is controlled to perform a corresponding task based on a determined discharge mode, the application can send an early warning to the user by SMS, phone call, or push notification, so as to promptly remind the user to take necessary protective measures.

[0112] like Figure 7 As shown, the tablet computer 30 is placed on a seat 40 in a high-temperature closed car. When it is detected that the tablet computer is controlled to perform a corresponding task based on a determined discharge mode, the application set in the tablet computer 30 can send an early warning to the user's mobile phone 50 via SMS, phone call or push notification, thereby reminding the user to take necessary protective measures in time.

[0113] In the above embodiment, the shielding state of the electronic device can be determined by a first environment image captured by a camera of the electronic device, or by a second environment image captured by a camera in the environment where the electronic device is located (e.g., a vehicle-mounted camera). Of course, the shielding state of the electronic device can also be determined by both the first environment image and the second environment image.

[0114] When the first environment image captured by the camera of the electronic device is used for determination: the camera of the electronic device is started, and based on the current first environment image captured by the camera, it is determined that the electronic device is in a front-side blocking state or a back-side blocking state.

[0115] When the judgment is made through the second environment image taken by the vehicle-mounted camera device: obtain the current second environment image taken by the vehicle-mounted camera device, the current second environment image includes the electronic device, and determine based on the current environment image whether the electronic device is in a front occlusion state or a back occlusion state.

[0116] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
