Technical Field

[0001] This application relates to the general data processing technology field of the Internet industry, and in particular to a device control method, apparatus, storage medium and program for a cockpit based on abnormal child posture events. Background Technology

[0002] With the increasing prevalence of vehicles, it has become more common to travel with children. To ensure children's safety while traveling, child seats have emerged.

[0003] However, children may exhibit improper behavior in child seats while the vehicle is in motion. For example, a child's neck may dangle outside the seat while sleeping, potentially leading to a stiff neck. Such improper behavior can affect a child's health. Therefore, how to handle improper behavior by children in child seats is a problem that needs to be addressed. Summary of the Invention

[0004] This application discloses a device control method and apparatus for a child's abnormal posture in a cockpit. When a child exhibits abnormal behavior (e.g., an incorrect sleeping posture) in a smart child safety seat, the user is prompted to adjust the child's sleeping posture in a timely manner, thereby effectively ensuring the child's health.

[0005] In a first aspect, embodiments of this application provide a device control method in a cockpit based on abnormal child posture events, applied to an intelligent cockpit domain controller in a vehicle's domain controller system. The domain controller system includes the intelligent cockpit domain controller and an intelligent child safety seat communicatively connected to the intelligent cockpit domain controller. The method includes the following steps:

[0006] Obtain the child's current first sleeping position in the smart child safety seat;

[0007] Determine whether the first sleeping position is an abnormal sleeping position. The abnormal sleeping positions include: a sleeping position with the head tilted at an angle exceeding a preset head tilt angle, a sleeping position with the head tilted back at an angle exceeding a preset head tilt angle, and a sleeping position with the head suspended in the air.

[0008] If the first sleeping position is the abnormal sleeping position, query the database for the preset abnormal sleeping position adjustment set of the smart child safety seat, and determine whether the smart child safety seat has an auxiliary adjustment function for the first sleeping position;

[0009] When the smart child safety seat has an auxiliary adjustment function for the first sleeping position, the smart child safety seat is controlled to adjust the child's current first sleeping position to a standard sleeping position according to the retrieved auxiliary adjustment strategy for the first sleeping position.

[0010] If the intelligent child safety seat does not have an auxiliary adjustment function for the first sleeping position, the first control information is determined based on the first sleeping position and sent to the output device. The output device is controlled to prompt the user to adjust the child's first sleeping position to the target sleeping position, which is a standard sleeping position. The output device includes at least one of the following: a speaker, a central control display screen, a passenger display screen, a rear display screen, or a ceiling-mounted display screen, which are controlled by the intelligent cockpit domain controller.

[0011] Secondly, embodiments of this application provide a device control apparatus in a cockpit based on abnormal child posture events, applied to an intelligent cockpit domain controller in a vehicle's domain controller system. The domain controller system includes the intelligent cockpit domain controller and an intelligent child safety seat communicatively connected to the intelligent cockpit domain controller. The apparatus includes:

[0012] The acquisition unit is used to acquire the current first sleeping position of the child in the smart child safety seat;

[0013] The processing unit is configured to determine whether the first sleeping posture is an abnormal sleeping posture, the abnormal sleeping posture including at least one of the following: a sleeping posture with a head tilt angle exceeding a preset head tilt angle, a sleeping posture with a head tilt angle exceeding a preset head tilt angle, and a sleeping posture with the head suspended in the air; and, if the first sleeping posture is the abnormal sleeping posture, to query the database for a preset abnormal sleeping posture adjustment set of the smart child safety seat, and to determine whether the smart child safety seat has an auxiliary adjustment function for the first sleeping posture.

[0014] The control unit is configured to, when the intelligent child safety seat has an auxiliary adjustment function for the first sleeping position, control the intelligent child safety seat to adjust the child's current first sleeping position to a standard sleeping position according to a queried auxiliary adjustment strategy for the first sleeping position; and, when the intelligent child safety seat does not have an auxiliary adjustment function for the first sleeping position, determine first control information based on the first sleeping position and send the first control information to an output device, controlling the output device to prompt the user to adjust the child's first sleeping position to a target sleeping position, wherein the target sleeping position is a standard sleeping position, and the output device includes at least one of a speaker, a central control display screen, a passenger-side display screen, a rear-seat display screen, or a ceiling-mounted display screen controlled by the intelligent cockpit domain controller.

[0015] Thirdly, embodiments of this application provide an electronic device including a processor and a memory interconnected thereto, wherein the memory is used to store a computer program, the computer program including program instructions, and the processor is configured to invoke the program instructions to execute the method as described in the first aspect.

[0016] Fourthly, embodiments of this application provide a computer-readable storage medium storing a computer program, the computer program including program instructions that, when executed by a processor, cause the processor to perform the method described in the first aspect.

[0017] Fifthly, embodiments of this application provide a computer program product, the computer program product including a non-transitory computer-readable storage medium storing a computer program, the computer being operable to perform the method as described in the first aspect.

[0018] Implementing this application embodiment involves obtaining the child's current first sleeping position in the smart child safety seat and determining whether the first sleeping position is an abnormal sleeping position. If the first sleeping position is abnormal, the system queries the database for a preset abnormal sleeping position adjustment set for the smart child safety seat to determine whether the smart child safety seat has an auxiliary adjustment function for the first sleeping position. If the smart child safety seat has an auxiliary adjustment function for the first sleeping position, the system controls the smart child safety seat to adjust the child's current first sleeping position to a standard sleeping position according to the queried auxiliary adjustment strategy for the first sleeping position. If the smart child safety seat does not have an auxiliary adjustment function for the first sleeping position, the system determines first control information based on the first sleeping position and sends the first control information to an output device, controlling the output device to prompt the user to adjust the child's first sleeping position to a target sleeping position. The target sleeping position is a standard sleeping position, which can improve the intelligence and comprehensiveness of the vehicle's intelligent cockpit domain controller in handling abnormal child posture events, reduce the probability of harm to the child's health due to failure to handle abnormal child posture events in a timely manner, and improve the safety of children riding in the car.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0028] The terms "first" and "second," etc., used in the specification and drawings of this application are used to distinguish different objects or to differentiate different treatments of the same object, rather than to describe a specific order of objects. Furthermore, the terms "comprising" and "having," and any variations thereof, used in the description of this application are intended to cover non-exclusive inclusion.

[0029] It should be noted that in the embodiments of this application, the words "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design method described as "exemplarily" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of the words "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner. In the embodiments of this application, "A and / or B" means both A and B, or A or B. "A, and / or B, and / or C" means any one of A, B, and C, or any two of A, B, and C, or A, B, and C.

[0030] Please see Figure 1 , Figure 1This is a schematic diagram of the architecture of an automotive-grade intelligent cockpit domain controller provided in an embodiment of this application. Figure 1 As shown, traditional automotive functions include the powertrain domain, chassis domain, and body domain. Emerging automotive functions may include the intelligent cockpit domain, autonomous driving domain, and so on. The intelligent cockpit domain implements numerous functions, including infotainment, human-machine interaction, and over-the-air (OTA) technology upgrades. The autonomous driving domain can achieve vehicle autonomous driving through the combination of LiDAR, millimeter-wave radar, cameras, algorithms, and various interfaces. Different controllers can be set for different domains. For example, a microcontroller unit (MCU). Of course, multiple domains can share a single controller. This application does not limit the number of controllers for each domain, and multiple controllers can be configured for one domain. The aforementioned controllers can also be general-purpose processors, image processors, or other processors with higher computing power.

[0031] With the increasing prevalence of vehicles, it has become more common to travel with children. To ensure children's safety while traveling, child seats have emerged.

[0032] However, children may exhibit improper behavior in child seats while the vehicle is in motion. For example, a child's neck may dangle outside the seat while sleeping, potentially leading to a stiff neck. Such improper behavior can affect a child's health. Therefore, how to handle improper behavior by children in child seats is a problem that needs to be addressed.

[0033] Please see Figure 2 , Figure 2 This is a flowchart illustrating a device control method in a cockpit based on abnormal child posture events, provided as an embodiment of this application. The method utilizes a smart cockpit domain controller within a vehicle's domain controller system. The domain controller system includes the smart cockpit domain controller and a smart child safety seat communicatively connected to the smart cockpit domain controller. The method may include the following steps S201-S204:

[0034] Step S201: Obtain the child's current first sleeping position in the smart child safety seat.

[0035] In one possible implementation, obtaining the child's current first sleeping position in the smart child safety seat may include the following steps A1-A4:

[0036] Step A1: Receive image data collected by at least one camera device on the vehicle, wherein the at least one camera device is communicatively connected to the intelligent cockpit domain controller.

[0037] The camera device can be installed in any location, such as the rearview mirror. In practical applications, it can also be installed in other locations, such as the rear of a door or the rear of the front seats. This application embodiment does not limit this. The image data includes at least one of image data and video data. The at least one camera device is communicatively connected to the intelligent cockpit domain controller and can send the collected image data to the intelligent cockpit domain controller.

[0038] The camera device may send the image data collected within the preset period to the smart cockpit domain controller, or the smart cockpit domain controller may send a request for image data to the camera device, and the camera device may send the image data collected within the preset period to the smart cockpit domain controller after receiving the request. This application embodiment does not limit this.

[0039] Step A2: Determine whether the child is asleep based on the image data.

[0040] For example, when the image data is picture image data, if it is detected that the child in the preset number of consecutively received pictures is in a closed-eye state, it can be determined that the child is in a sleeping state.

[0041] For example, when the image data is video image data, if it is detected that the child is in a state of continuous eye-closing in the video image data, it can be determined that the child is in a sleeping state.

[0042] Step A3: While the child is asleep, extract the child's sleeping posture image data from the image data.

[0043] Since the video data may include other video data besides the child's sleeping posture, such as seat video data and window video data, the intelligent cockpit domain controller can extract the child's sleeping posture video data from the video data.

[0044] Step A4: Determine the child's current first sleeping position based on the sleeping position image data.

[0045] The intelligent cockpit domain controller can analyze the sleeping posture image data to obtain the current sleeping posture represented by the sleeping posture image data, which is the first sleeping posture.

[0046] In one possible implementation, obtaining the child's current first sleeping position in the smart child safety seat may include the following steps B1-B6:

[0047] Step B1: Obtain pressure data fed back by pressure sensors configured at various locations on the smart child safety seat.

[0048] Pressure sensors can be configured in any location on a smart child safety seat, such as on one or more of the seat cushion, backrest, or seat belt.

[0049] The pressure sensor may send the pressure data collected within the preset period to the intelligent cockpit domain controller, or the intelligent cockpit domain controller may send a request for pressure data to the pressure sensor, and the pressure sensor may send the pressure data collected within the preset period to the intelligent cockpit domain controller after receiving the request. This application embodiment does not limit this.

[0050] Step B2: Determine whether the child is asleep based on the stress data obtained in the current cycle and the stress data obtained in the previous cycle.

[0051] When children are asleep, their body (limb) postures don't change much; that is, the frequency of change is relatively low. However, when children are awake, their body (limb) postures are more likely to change constantly; that is, the frequency of change is relatively high. Therefore, stress data from the current cycle can be compared with stress data from the previous cycle to determine whether a child is asleep.

[0052] Step B3: If the number of locations where the pressure data changes is less than a preset number, it is determined that the child is asleep.

[0053] Although a child's body posture doesn't change much while asleep, subtle changes can still occur. Therefore, whether a child is asleep can be determined by whether the number of locations where pressure data changes compared to the previous cycle is less than a preset number. For example, if the number of locations where pressure data changes compared to the previous cycle is less than the preset number, the child is asleep; if the number of locations where pressure data changes compared to the previous cycle is greater than the preset number, the child is not asleep. Furthermore, since a child's body posture doesn't change much while asleep, whether a child is asleep can also be determined by whether the range of changes in pressure data at various locations in the current cycle compared to the previous cycle falls within a preset range. For example, if the range of change in pressure data at each location in the current cycle compared to the range of change in pressure data at each location in the previous cycle is within a preset range, the child is determined to be asleep; if the range of change in pressure data at each location in the current cycle compared to the range of change in pressure data at each location in the previous cycle exceeds the preset range of change in pressure data, the child is determined to be not asleep. Furthermore, a comprehensive judgment can be made based on whether the number of locations where pressure data changes compared to the pressure data at each location in the current cycle is less than a preset number, and whether the range of change in pressure data at each location in the current cycle compared to the pressure data at each location in the previous cycle is within the preset range of change in pressure data.

[0054] Step B4: Generate the first force diagram corresponding to the first sleeping position based on the pressure data obtained in the current cycle.

[0055] When a child is in different sleeping positions, the pressure data at various locations will not be exactly the same in different sleeping positions. Therefore, a first pressure map corresponding to the current first sleeping position can be generated based on the pressure data of various locations obtained in the current cycle.

[0056] Step B5: Obtain the preset standard sleeping posture force diagram stored in the database.

[0057] The database stores preset standard sleeping position force maps, which can be derived from pre-analyzed force data of various positions in a smart child safety seat under standard sleeping positions. Understandably, there can be more than one standard sleeping position force map. Furthermore, the standard sleeping position force maps stored in the database can be continuously updated.

[0058] Step B6: Based on the difference between the first force diagram and the preset standard sleeping position force diagram, obtain the child's current first sleeping position.

[0059] For example, if the standard sleeping posture force diagram contains force data for five positions: M1, N1, P1, Q1, and R1, and the corresponding force data for the five positions in the first force diagram are M1, N1, P2, Q1, and R2, then based on the standard sleeping posture corresponding to the standard sleeping posture in the standard sleeping posture force diagram, the deviation of the positions corresponding to force data P2 and force data R2 in the first force diagram from the standard sleeping posture can be determined. Furthermore, the deviation of the first sleeping posture from the standard sleeping posture can be determined based on the difference between P1 and P2 and the difference between R1 and R2, thus allowing the child's current first sleeping posture to be determined based on the deviation and the standard sleeping posture.

[0060] Step S202: Determine whether the first sleeping position is an abnormal sleeping position.

[0061] Abnormal sleeping positions include at least one of the following: a head tilt angle exceeding a preset head tilt angle, a head tilt angle exceeding a preset head tilt angle, and a head-suspended position. Abnormal sleeping positions can be pre-stored in a database. It is understood that there can be more than one abnormal sleeping position. Furthermore, the abnormal sleeping positions stored in the database can be continuously updated.

[0062] The first sleeping position is compared sequentially with abnormal sleeping positions to determine whether the first sleeping position is one of the abnormal sleeping positions, which is a non-standard sleeping position. For example, if the first sleeping position is one of the abnormal sleeping positions, it is determined to be a non-standard sleeping position; if the first sleeping position is not one of the abnormal sleeping positions, it is determined to be a standard sleeping position. A standard sleeping position is one that will not cause a child to suffer from a stiff neck or affect the child's health.

[0063] Step S203: If the first sleeping position is the abnormal sleeping position, query the database for the preset abnormal sleeping position adjustment set of the smart child safety seat, and determine whether the smart child safety seat has an auxiliary adjustment function for the first sleeping position.

[0064] In practice, users may not notice if a child's sleeping posture is incorrect, or it may be inconvenient for the user to adjust the child's sleeping position. Therefore, the smart cockpit domain controller can autonomously control the smart child safety seat to adjust the child's sleeping position. However, due to the diversity of smart child safety seats, some may not have this function. Therefore, if the child's initial sleeping position is not the standard position, the system can query the database's preset anomaly set for smart child safety seats to determine if there is an adjustment scheme for the current initial sleeping position.

[0065] Step S204: If the smart child safety seat has an auxiliary adjustment function for the first sleeping position, control the smart child safety seat to adjust the child's current first sleeping position to a standard sleeping position according to the queried auxiliary adjustment strategy for the first sleeping position.

[0066] If a smart child safety seat has the function of assisting in adjusting sleeping posture, the smart cockpit domain controller can control the smart child safety seat to adjust the child's first sleeping posture to the target sleeping posture.

[0067] In one possible implementation, if the first sleeping position is a head tilt angle exceeding a preset head tilt angle, and the preset abnormal sleeping position adjustment set includes a first auxiliary adjustment strategy for the sleeping position with the head tilt angle exceeding the preset head tilt angle, then the first auxiliary adjustment strategy may include the following operations:

[0068] When a child's primary sleeping position is with their head tilted to the right, the smart child safety seat will adjust to the leftward tilt until the image capture and detection system determines that the child's head tilt angle no longer exceeds the preset tilt angle.

[0069] When a child's primary sleeping position is with their head tilted to the left, the smart child safety seat will adjust to the rightward tilt until the image capture and detection system determines that the child's head tilt angle no longer exceeds the preset angle.

[0070] In car travel scenarios, children may eat while in a smart child safety seat, which could lead to them falling asleep while eating. Children eating (such as chunks of food or candy) are prone to choking and may even suffocate. Therefore, it's possible to detect whether a child has food in their mouth while asleep, allowing for timely warnings to other passengers about the potential choking or suffocation risk.

[0071] In one possible implementation, if the first sleeping position is a sleeping position with a head tilt angle exceeding a preset head tilt angle, and the preset abnormal sleeping position adjustment set includes a second auxiliary adjustment strategy for sleeping positions with a head tilt angle exceeding the preset head tilt angle, then the second auxiliary adjustment strategy may include the following operations:

[0072] Acquire cached image information of the child before the child is in the first sleeping position and the acquisition time of the image information;

[0073] If, based on the image information and the acquisition time, it is determined that the child consumed a block of food before going to sleep, and the time between the consumption and the current system time is less than or equal to a first preset time, then the user is reminded to check the child's oral condition via the speaker of the smart child safety seat; and the user is also reminded to correct the child's head posture.

[0074] If, based on the image information and the acquisition time, it is determined that the child ate a block of food before going to sleep, and the duration between the time of consumption and the current system time is greater than the first preset duration, then the smart child safety seat is first controlled to vibrate for a second preset duration, and the child is detected to continue moving due to physical discomfort.

[0075] If continuous movement is detected, the speaker of the smart child safety seat will be activated to remind the user to check the child's oral cavity and to remind the user to correct the child's head posture.

[0076] If no continuous action is detected, the smart child safety seat is controlled to lower the tilt angle of the backrest until the child's head tilt angle is determined by image acquisition and image detection to no longer exceed the preset head tilt angle.

[0077] If it is determined from the image information and the acquisition time that the child did not eat any block food before going to bed, then the smart child safety seat will be controlled to lower the tilt angle of the backrest until the image acquisition and image detection identification determine that the child's head tilt angle no longer exceeds the preset head tilt angle.

[0078] Specifically, this could involve: after the camera device captures image information, it stores the image information and the capture time. If a sleep event is detected (i.e., the child is in their first sleeping position), based on the cached image information from before the child entered the first sleeping position and the capture time, it can be determined whether the child ate any solid food before sleeping (e.g., within a third preset time range before the child entered the first sleeping position). For example, if a lollipop stick is visible outside the mouth in the image, or if solid food can be identified in an image where the child's mouth is open, or if the child's mouth appears bulging compared to a normal image without solid food, it can be determined that the child ate solid food before sleeping. Alternatively, it can also be determined based on sound or speech captured by the microphone. For example, if the received sound contains smacking sounds while eating, or if the user's words when giving the child candy include phrases like "Here's some candy," "Eat candy," "Want some candy?" "Want some food?" or "Eat something," it can be determined that the child ate solid food before sleeping. If it is determined that the child consumed a piece of food before bedtime, and the time between consumption and the current system time is greater than the first preset duration, the smart child safety seat will first vibrate for a second preset duration and detect whether the child continues to move due to discomfort. This can be determined by whether the force applied to the child changes or whether the child's sleeping posture changes. Controlling the vibration of the smart child safety seat can, to some extent, prevent the child from choking on food in their mouth. If continuous movement is detected, it indicates that the child may be experiencing discomfort due to the food in their mouth, such as it being stuck in their throat. Therefore, if continuous movement is detected, the speaker of the smart child safety seat can be controlled to remind the user to check the child's oral cavity. For example, the speaker can send a message such as, "The child is currently sleeping with sugar in their mouth and their head is tilted back too far, which could easily cause choking or suffocation. Please check the child's oral cavity immediately." The user can also be reminded to correct the child's head posture. If no continuous movement is detected, the smart child safety seat will adjust its backrest tilt angle downwards until the child's head tilt angle is determined to no longer exceed the preset head tilt angle through image acquisition and image detection. If the image information and acquisition time determine that the child did not eat any chunks of food before going to sleep, the smart child safety seat will adjust its backrest tilt angle downwards until the child's head tilt angle is determined to no longer exceed the preset head tilt angle through image acquisition and image detection.

[0079] In one possible implementation, if the first sleeping position is a head-suspended position, and the preset abnormal sleeping position adjustment set includes a third auxiliary adjustment strategy for the head-suspended position, then the third auxiliary adjustment strategy may include the following operations:

[0080] The system adjusts the tilt angle of the smart child safety seat backrest until it is determined through image acquisition and detection that the child's head is no longer suspended in the air.

[0081] It is understood that the above are some possible ways to adjust the first sleeping position to the target sleeping position. Other methods can also be used to adjust the first sleeping position to the target sleeping position, and the embodiments of this application do not limit this.

[0082] Furthermore, even when a smart child safety seat has a function to assist in adjusting sleeping position, the smart cockpit domain controller may still be unable to control the smart child safety seat to adjust the child's initial sleeping position to the target sleeping position if the child deviates from the target sleeping position by more than the preset adjustable range. Therefore, when a smart child safety seat has a function to assist in adjusting sleeping position, it is advisable to first determine whether the child's initial sleeping position deviates from the target sleeping position by more than the preset adjustable range. If the child's initial sleeping position deviates from the target sleeping position by no more than the preset adjustable range, the smart cockpit domain controller can control the smart child safety seat to adjust the child's initial sleeping position to the target sleeping position.

[0083] In one possible implementation, if the smart cockpit domain controller controls the smart child safety seat to adjust the child's first sleeping position to the target sleeping position, it can also send a control information control output device to notify the user that the smart cockpit domain controller has controlled the smart child safety seat to adjust the child's first sleeping position to the target sleeping position.

[0084] Step S205: If the smart child safety seat does not have an auxiliary adjustment function for the first sleeping position, determine the first control information based on the first sleeping position and send the first control information to the output device, and control the output device to prompt the user to adjust the child's first sleeping position to the target sleeping position.

[0085] If the smart child safety seat does not have the function of assisting in adjusting the sleeping position, it needs to send the first control information, and the control output device will prompt the user to help adjust the child's first sleeping position to the target sleeping position.

[0086] Alternatively, if the smart child safety seat has the function of assisting in adjusting the sleeping position, and the child's first sleeping position deviates from the target sleeping position by more than the preset adjustable range, then it is necessary to send the first control information, and the control output device prompts the user to adjust the child's first sleeping position to the target sleeping position.

[0087] The target sleeping position is the standard sleeping position. The output device includes at least one of the following: a speaker, a central control display screen, a passenger-side display screen, a rear-seat display screen, or a ceiling-mounted display screen, all controlled by the intelligent cockpit domain controller. For example, when the output device includes a speaker, it can be controlled to send a prompt such as "The child's current sleeping position has deviated from the standard sleeping position; please help the child adjust their sleeping position promptly" to prompt the user to adjust the child's first sleeping position to the target sleeping position. When the output device includes at least one of the following: a central control display screen, a passenger-side display screen, a rear-seat display screen, or a ceiling-mounted display screen, it can display the child's current first sleeping position and / or the target sleeping position to which the child needs to be adjusted, to prompt the user to adjust the child's first sleeping position to the target sleeping position.

[0088] By acquiring the child's current first sleeping position in the smart child safety seat and determining whether the first sleeping position is an abnormal sleeping position; if the first sleeping position is an abnormal sleeping position, the system queries the database for the smart child safety seat's preset abnormal sleeping position adjustment set to determine whether the smart child safety seat has an auxiliary adjustment function for the first sleeping position; if the smart child safety seat has an auxiliary adjustment function for the first sleeping position, the system controls the smart child safety seat to adjust the child's current first sleeping position to a standard sleeping position according to the queried auxiliary adjustment strategy for the first sleeping position; if the smart child safety seat does not have an auxiliary adjustment function for the first sleeping position, the system determines first control information based on the first sleeping position and sends the first control information to the output device, controlling the output device to prompt the user to adjust the child's first sleeping position to the target sleeping position. The target sleeping position is a standard sleeping position, which can effectively prevent children from suffering from stiff necks or other health problems due to non-standard (non-standard) sleeping positions, thereby improving the automation level of the smart cockpit domain controller and enhancing the user experience.

[0089] In one possible implementation, if the user's adjusted sleeping position is not the target sleeping position, then after a preset adjustment time interval following the user's initial adjustment of the first sleeping position, it is determined whether the adjusted sleeping position is the target sleeping position. If it is determined that the adjusted sleeping position is not the target sleeping position, then a third control message is sent to the output device, which prompts the user to adjust the child's sleeping position again.

[0090] Please see Figure 3 , Figure 3 A flowchart illustrating another device control method in a cockpit based on abnormal child posture events provided in this application embodiment may include the following steps S301-S307:

[0091] Step S301: Obtain the child's current first sleeping position in the smart child safety seat.

[0092] Step S302: Determine whether the first sleeping position is an abnormal sleeping position.

[0093] Step S303: If the first sleeping position is the abnormal sleeping position, query the database for the preset abnormal sleeping position adjustment set of the smart child safety seat, and determine whether the smart child safety seat has an auxiliary adjustment function for the first sleeping position.

[0094] Step S304: If the smart child safety seat has an auxiliary adjustment function for the first sleeping position, control the smart child safety seat to adjust the child's current first sleeping position to a standard sleeping position according to the retrieved auxiliary adjustment strategy for the first sleeping position.

[0095] Step S305: If the smart child safety seat does not have an auxiliary adjustment function for the first sleeping position, determine the first control information based on the first sleeping position and send the first control information to the output device, and control the output device to prompt the user to adjust the child's first sleeping position to the target sleeping position.

[0096] The specific implementation methods of steps S301-S305 can be found in [reference]. Figure 2 The specific implementation methods of steps S201-S205 shown will not be elaborated here.

[0097] Step S306: Within a first preset time range, if the child's sleeping position changes from the target sleeping position to the first sleeping position, then determine whether the smart child safety seat is in the position directly facing the air conditioner vent.

[0098] If, within a first preset time period after adjusting a child's sleeping position from their primary sleeping position to the target sleeping position, the child's sleeping position reverts back to the primary sleeping position, it indicates that external factors may be causing discomfort in the target sleeping position. Therefore, if, within the first preset time period after adjusting the child's sleeping position from the primary to the target sleeping position, the child's sleeping position reverts back to the primary sleeping position, the cause of the discomfort can be analyzed. For example, it might be because the smart child safety seat is directly facing the air conditioner vent. Therefore, it can be determined whether the smart child safety seat is directly facing the air conditioner vent. For example, by obtaining the temperature within a preset distance of the child and the temperature at other locations, if the difference between the temperature within the preset distance and the temperature at other locations exceeds a preset difference, it can be determined that the smart child safety seat is directly facing the air conditioner vent. Alternatively, image data can also be used to determine whether the smart child safety seat is directly facing the air conditioner vent. The above method for determining whether a smart child safety seat is in the direction of the air conditioner vent is merely an example, and this application does not limit this method.

[0099] Step S307: When the smart child safety seat is positioned directly opposite the air vent of the air conditioner, the smart cockpit domain controller adjusts the position of the smart child safety seat, or the smart cockpit domain controller adjusts the air vent position of the vehicle's air conditioner.

[0100] If the smart child safety seat is directly facing the air conditioning vent, this could be causing the child's sleeping posture to be incorrect (not in the standard sleeping position). Therefore, if the smart child safety seat is directly facing the air conditioning vent, the smart cockpit domain controller can adjust the position of the smart child safety seat, or adjust the position of the vehicle's air conditioning vent. Furthermore, the child's primary sleeping position can be readjusted to the target sleeping position.

[0101] By determining whether the smart child safety seat is directly facing the air conditioner vent, we can analyze whether the child's improper sleeping posture is caused by the smart child safety seat being directly facing the air conditioner vent. This can address the problem at its source, rather than causing the child to constantly change to an improper sleeping posture.

[0102] Please see Figure 4 , Figure 4 A flowchart illustrating another device control method in a cockpit based on abnormal child posture events provided in this application embodiment may include the following steps S401-S407:

[0103] Step S401: Obtain the child's current first sleeping position in the smart child safety seat.

[0104] Step S402: Determine whether the first sleeping position is an abnormal sleeping position.

[0105] Step S403: If the first sleeping position is the abnormal sleeping position, query the database for the preset abnormal sleeping position adjustment set of the smart child safety seat, and determine whether the smart child safety seat has an auxiliary adjustment function for the first sleeping position.

[0106] Step S404: If the smart child safety seat has an auxiliary adjustment function for the first sleeping position, control the smart child safety seat to adjust the child's current first sleeping position to a standard sleeping position according to the retrieved auxiliary adjustment strategy for the first sleeping position.

[0107] Step S405: If the smart child safety seat does not have an auxiliary adjustment function for the first sleeping position, determine the first control information based on the first sleeping position and send the first control information to the output device, and control the output device to prompt the user to adjust the child's first sleeping position to the target sleeping position.

[0108] The specific implementation methods of steps S401-S405 can be found in [reference]. Figure 2 The specific implementation methods of steps S201-S205 shown will not be elaborated here.

[0109] Step S406: Within the second preset time range, if the child's sleeping position changes from the target sleeping position to the first sleeping position, then determine whether the child's face is in a position exposed to sunlight.

[0110] Within a second preset time period after adjusting the child's sleeping position from the first sleeping position to the target sleeping position, if the child's sleeping position changes back to the first sleeping position, it indicates that there may be external factors causing discomfort when the child was in the target sleeping position. Therefore, if the child's sleeping position changes back to the first sleeping position within the second preset time period after adjusting from the first sleeping position to the target sleeping position, the cause of the child's discomfort can be analyzed. For example, it's possible that the child's face is in a position exposed to sunlight, causing discomfort and leading to the first sleeping position. Therefore, it's possible to determine whether the child's face is in a position exposed to sunlight. For example, by obtaining the temperature within a preset distance of the child and the temperature of other locations, if the difference between the temperature within the preset distance of the child and the temperature of other locations exceeds a preset difference, it can be determined that the child's face is in a position exposed to sunlight. Alternatively, it can be determined through image data. Or, it can be determined by obtaining the difference between the light intensity within the preset distance of the child and the light intensity of other locations and whether it exceeds a preset light intensity difference. The above method for determining whether a smart child safety seat is in the direction of the air conditioner vent is merely an example, and this application does not limit this method.

[0111] Step S407: When the child's face is in a position exposed to sunlight, the smart cockpit domain controller opens the sunshade of the smart child safety seat, or raises the sunshade on the window, or adjusts the position of the smart child safety seat.

[0112] If a child's face is exposed to sunlight, this could be the cause of an incorrect sleeping posture (not a standard sleeping posture). Therefore, when a child's face is exposed to sunlight, the smart cockpit domain controller can open the sunshade of the smart child safety seat; or, adjust the position of the smart child safety seat to a position where the child's face is not exposed to sunlight; or, raise the sunshade on the car window to prevent the child's face from being exposed to sunlight. This application embodiment does not limit this. Furthermore, the child's initial sleeping posture can be adjusted back to the target sleeping posture.

[0113] Analyzing whether a child's face is exposed to sunlight can help address the root cause of their incorrect sleeping posture, rather than encouraging them to constantly adopt these postures.

[0114] Please see Figure 5 , Figure 5 A flowchart illustrating another device control method in a cockpit based on abnormal child posture events provided in this application embodiment may include the following steps S501-S507:

[0115] Step S501: Obtain the child's current first sleeping position in the smart child safety seat.

[0116] Step S502: Determine whether the first sleeping position is an abnormal sleeping position.

[0117] Step S503: If the first sleeping position is the abnormal sleeping position, query the database for the preset abnormal sleeping position adjustment set of the smart child safety seat, and determine whether the smart child safety seat has an auxiliary adjustment function for the first sleeping position.

[0118] Step S504: If the smart child safety seat has an auxiliary adjustment function for the first sleeping position, control the smart child safety seat to adjust the child's current first sleeping position to a standard sleeping position according to the queried auxiliary adjustment strategy for the first sleeping position.

[0119] Step S505: If the intelligent child safety seat does not have an auxiliary adjustment function for the first sleeping position, determine the first control information based on the first sleeping position and send the first control information to the output device, and control the output device to prompt the user to adjust the child's first sleeping position to the target sleeping position.

[0120] The specific implementation methods of steps S501-S505 can be found in [reference]. Figure 2 The specific implementation methods of steps S201-S205 shown will not be elaborated here.

[0121] Step S506: Determine whether the seat belt of the smart child safety seat is located in the child's preset position based on the seat belt position image of the smart child safety seat collected by at least one camera device on the vehicle or the force data of the seat belt obtained by the sensor. The preset position includes at least one of the child's face, neck and arm.

[0122] In reality, if a seatbelt gets caught on a child's face, neck, or arm, it can cause discomfort or even pose a safety hazard. Therefore, it's possible to determine whether the smart child safety seat's seatbelt is in a preset position for the child by using images of the seatbelt position captured by at least one camera in the vehicle or by force data obtained from sensors. The preset position refers to a location that would cause discomfort or pose a safety hazard to the child, including but not limited to the child's face, neck, or arm.

[0123] Step S507: When the seat belt is in the preset position, send second control information to the output device to control the output device to prompt the user to adjust the seat belt to a non-preset position, or adjust the seat cushion of the smart child safety seat so that the seat belt is in the non-preset position.

[0124] A non-preset position refers to a position other than the preset position. For example, when the output device includes a speaker, the speaker can be controlled to send prompts such as "The current smart child safety seat belt is located at the child's face / neck / arm; please help the child adjust the seat belt in time" to prompt the user to adjust the seat belt. When the output device includes at least one of the following: a central control display screen, a passenger-side display screen, a rear-seat display screen, or a ceiling-mounted display screen, the above output devices can be used to display the current position of the smart child safety seat belt and / or the correct position to which the seat belt needs to be adjusted, to prompt the user to adjust the seat belt to a non-preset position. For example, tightening or loosening the upper or lower end of the seat belt can adjust its position to a non-preset position. Alternatively, adjusting the seat cushion of the smart child safety seat can move the seat belt to a non-preset position. For example, raising or lowering the seat cushion can cause the seat belt to no longer be in the preset position. This application embodiment does not limit this.

[0125] By determining whether the seat belt is in the preset position, children's safety and riding experience can be effectively guaranteed.
