Description

Technical Field

[0001] This invention relates to the field of automotive safety driving technology, and in particular to a method and system for controlling car windows to prevent children from falling out. Background Technology

[0002] Intelligent vehicles are a current trend and an essential mode of transportation. However, the problem of children falling out of car windows frequently arises, such as when starting from a red light without an adult in the back seat. Current solutions include installing security bars on the windows or simply keeping them closed. While security bars ensure safety, they also present aesthetic and other issues. Keeping the windows closed can lead to poor air circulation, affecting the driving experience. Summary of the Invention

[0003] This invention provides a method and system for controlling car windows to prevent children from falling out of them. The technical problem it solves is: how to determine whether there is a child in the car seat and control the car window according to the determination result, so that when there is a child, the maximum opening of the corresponding car window is controlled within a range that the child cannot fall out of, thereby avoiding the accident of children falling out of the car window, while maximizing the air circulation inside the car.

[0004] To solve the above technical problems, the present invention provides a method for controlling car windows to prevent children from falling out, comprising the following steps:

[0005] S1. Before starting the vehicle, determine whether there is a child in the vehicle seat. If yes, proceed to step S2; otherwise, proceed to step S3.

[0006] S2. Control the window corresponding to the car seat where a child is present to be in child safety mode. In the child safety mode, the opening degree of the window corresponding to the car seat where a child is present is adjustable within a preset maximum opening degree value.

[0007] S3. Control the window corresponding to the car seat where there is no child to be in the normal mode. In the normal mode, the opening degree of the window corresponding to the car seat where there is no child can be adjusted arbitrarily.

[0008] S4. When the vehicle starts, it continuously monitors whether the presence of children in the vehicle seats changes during the vehicle's operation. If so, it adjusts the corresponding window to the appropriate mode.

[0009] Further, step S1 specifically includes the following steps:

[0010] S11. Determine if there is a child in the vehicle seat. If yes, proceed to step S12; otherwise, proceed to step S3.

[0011] S12. Determine whether the child is wearing a seatbelt. If not, proceed to step S13. If yes, proceed to step S3.

[0012] S13. Obtain the child's shape information, calculate the preset maximum opening value in step S2 based on the shape information, and proceed to step S2.

[0013] Furthermore, in step S11, determining whether a child is in the vehicle seat is done through at least two of the following methods:

[0014] Judgment Method 1: A judgment button is set to determine whether there is a child in a seat other than the driver's seat. When the judgment button for the corresponding seat emits a judgment signal, it indicates that there is a child in that seat. If a denial signal is emitted, it indicates that there is no child in that seat.

[0015] Judgment Method 2: Pressure sensors are installed in seats other than the driver's seat. When the stable pressure increment value of the corresponding seat does not exceed the preset pressure threshold, it indicates that there is a child in that seat.

[0016] Method 3: Child recognition cameras are installed in seats other than the driver's seat. If the recognition result is a child, it indicates that there is a child in that seat.

[0017] When any two or all three judgment methods, including judgment method 1, are set, judgment method 1 is used first. If judgment method 1 determines that there is a child in the corresponding seat, the other judgment methods are not used, and it is determined that there is a child in the corresponding seat. If judgment method 1 determines that there is no child in the corresponding seat, if only one judgment method remains, the judgment result of the remaining single judgment method is followed. If two judgment methods remain, a child is determined to exist only if both judgment methods determine that there is a child in the corresponding seat. If the judgment results of the two judgment methods are inconsistent, the driver is requested to use judgment method 1 to determine whether there is a child in the corresponding seat.

[0018] When both judgment methods 2 and 3 are set, both methods will determine that there is a child in the corresponding seat. If the judgment results of the two methods are inconsistent, the final judgment will be that there is a child in the corresponding seat.

[0019] Furthermore, the driver is requested to use judgment method 1 to determine whether there is a child in the corresponding seat, specifically:

[0020] The system sends a voice prompt to the driver requesting confirmation of whether a child is in the corresponding seat. Within a first preset time period, the system receives a signal from the judgment button. If a confirmation signal is received within the first preset time period, it is determined that a child is in the seat corresponding to the confirmation signal. If a denial signal is received within the preset time period, it is determined that no child is in the seat corresponding to the denial signal. If no signal is received after the first preset time period, it is assumed that a child is in the corresponding seat.

[0021] Further, in step S12, determining whether the child is wearing a seatbelt specifically includes the following steps:

[0022] S121. Determine whether a child safety seat is installed on the corresponding vehicle seat. If yes, proceed to step S122; otherwise, proceed to step S123.

[0023] S122. Determine whether the child in the child safety seat is properly fastened with the seat belt. If yes, proceed to step S3; otherwise, proceed to step S13.

[0024] S123. Determine whether the child in the corresponding seat is wearing a seatbelt. If yes, proceed to step S3; otherwise, proceed to step S13.

[0025] Further, in S122, determining whether the child in the child safety seat is wearing a seatbelt specifically involves:

[0026] Check if all seat belt buckles on the child safety seat are fastened. If so, the child is considered to be wearing a seat belt; otherwise, the child is considered not to be wearing a seat belt.

[0027] Pressure sensors are installed in seats other than the driver's seat, and human age estimation modules are installed in seats other than the driver's seat. In step S123, it is determined whether the child in the corresponding seat is wearing a seat belt, specifically:

[0028] The system obtains the stable pressure increment value of the seat through the pressure sensor on the corresponding seat. If the stable pressure increment value is less than the preset pressure threshold, it is determined that the child in the seat is not wearing a seat belt. If the stable pressure increment value is not less than the preset pressure threshold, the human age estimation module is activated to estimate the child's age. If the child is under 12 years old, it is determined that the child in the seat is not wearing a seat belt. If the child is 12 years old or older, the system obtains the seat belt locking information. If the seat belt is locked, it is determined that the child in the seat is wearing a seat belt. If the seat belt is unlocked, it is determined that the child in the seat is not wearing a seat belt. At this time, a voice reminder to fasten the seat belt is issued. If the seat belt locks within a second preset time period, it is determined that the child in the seat is wearing a seat belt. If the seat belt is still not locked, it is determined that the child in the seat is not wearing a seat belt.

[0029] Further, in step S13, the acquired physical information of the child includes height H, minimum head diameter D, and the preset maximum opening value K is calculated by the following formula:

[0030]

[0031] in, This indicates rounding down to the nearest integer.

[0032] Furthermore, the child's height H is either written by the driver or estimated through a three-dimensional human body scan using the child recognition camera;

[0033] The minimum diameter D of a child's head is estimated based on the height H, weight W, and head size α written by the driver, or estimated by performing a three-dimensional human body scan using the child recognition camera.

[0034] Furthermore, in step S4, the presence status of the child in the vehicle seat is detected in real time to see if there is a change, specifically:

[0035] If the window corresponding to the seat is in child safety mode, the system will re-evaluate the situation every third preset time period using a method other than judgment method 1. If all judgment methods re-evaluate that there is no child in the seat, the system will request the driver to use judgment method 1 to determine whether there is a child in the corresponding seat. When the driver confirms that there is no child in the seat by operating the judgment case, the window will be adjusted to normal mode. Otherwise, the window will remain in child safety mode.

[0036] If the window corresponding to the seat is in the normal mode, the system will re-evaluate the situation every third preset time period using a method other than judgment method 1. If one or more judgment methods re-evaluate that there is a child in the seat, the window will be directly adjusted to the child safety mode. Otherwise, the window will remain in the normal mode.

[0037] This invention also provides a window control system based on the above-mentioned child-prevention window control method. The key features are: a child detection module and a window control module. The child detection module is used to determine whether a child is in the vehicle seat before the vehicle starts and while the vehicle is in motion, and sends the relevant detection result to the window control module. The window control module is used to control the opening degree of the corresponding seat window according to the detection result. Specifically:

[0038] When the determination result is that a child is present, the window corresponding to the seat where the child is present is controlled to be in child safety mode. In child safety mode, the opening degree of the window corresponding to the seat where the child is present is adjustable within a preset maximum opening degree value.

[0039] When the determination result is that there are no children, the window corresponding to the seat where there are no children is controlled to be in normal mode. In the normal mode, the opening degree of the window corresponding to the seat where there are no children can be adjusted arbitrarily.

[0040] This invention provides a method and system for controlling car windows to prevent children from falling out. It can automatically adjust the adjustment mode of the corresponding car window according to whether there is a child in the vehicle seat. Different adjustment modes have different opening adjustment ranges. It can ensure the safety of children when the vehicle is started and while the vehicle is in motion. Even if there is no adult accompanying the child in the back seat, the rear windows of the vehicle can be adjusted to a certain opening to ensure the ventilation of the vehicle.

[0041] Figure 1 This is an overall flowchart of a car window control method for preventing children from falling out of car windows, provided by an embodiment of the present invention;

[0042] Figure 2 This is a detailed flowchart of step S1 provided in an embodiment of the present invention;

[0043] Figure 3 This is a flowchart illustrating the specific steps in step S12 of this invention, specifically determining whether the child has fastened their seatbelt. Detailed Implementation

[0044] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. The embodiments are given for illustrative purposes only and should not be construed as limiting the present invention. The accompanying drawings are for reference and illustration only and do not constitute a limitation on the scope of patent protection of the present invention, because many changes can be made to the present invention without departing from the spirit and scope of the present invention.

[0045] First, this invention provides a method for controlling car windows to prevent children from falling out, such as... Figure 1 The flowchart shown includes the following steps:

[0046] S1. Before starting the vehicle, determine whether there is a child in the vehicle seat. If yes, proceed to step S2; otherwise, proceed to step S3.

[0047] S2. Control the window corresponding to the car seat where a child is present to be in child safety mode. In child safety mode, the opening degree of the window corresponding to the car seat where a child is present can be adjusted within the preset maximum opening degree value.

[0048] S3. Control the window corresponding to the car seat without a child to be in normal mode. In normal mode, the opening degree of the window corresponding to the car seat without a child can be adjusted arbitrarily.

[0049] S4. When the vehicle starts, it continuously monitors whether the presence of children in the vehicle seats changes during the vehicle's operation. If so, it adjusts the corresponding window to the appropriate mode.

[0050] like Figure 2 As shown, step S1 specifically includes the following steps:

[0051] S11. Determine if there is a child in the vehicle seat. If yes, proceed to step S12; otherwise, proceed to step S3.

[0052] S12. Determine whether the child is wearing a seatbelt. If not, proceed to step S13. If yes, proceed to step S3.

[0053] S13. Obtain the child's shape information, calculate the preset maximum opening value in step S2 based on the shape information, and proceed to step S2.

[0054] In step S11, determining whether there is a child in the vehicle seat is done using at least two of the following methods:

[0055] Judgment Method 1: A judgment button is set to determine whether there is a child in a seat other than the driver's seat. When the judgment button for the corresponding seat emits a judgment signal, it indicates that there is a child in that seat. If a denial signal is emitted, it indicates that there is no child in that seat.

[0056] Judgment Method 2: Pressure sensors are installed in seats other than the driver's seat. When the stable pressure increment value of the corresponding seat does not exceed the preset pressure threshold, it indicates that there is a child in that seat.

[0057] Method 3: Child recognition cameras are installed in seats other than the driver's seat. If the recognition result is a child, it indicates that there is a child in that seat.

[0058] When any two or all three judgment methods, including judgment method 1, are set, judgment method 1 is used first. If judgment method 1 determines that there is a child in the corresponding seat, the other judgment methods are not used, and it is determined that there is a child in the corresponding seat. If judgment method 1 determines that there is no child in the corresponding seat, if only one judgment method remains, the judgment result of the remaining single judgment method is followed. If two judgment methods remain, a child is determined to exist only if both judgment methods determine that there is a child in the corresponding seat. If the judgment results of the two judgment methods are inconsistent, the driver is requested to use judgment method 1 to determine whether there is a child in the corresponding seat.

[0059] When both judgment methods 2 and 3 are set, the system will determine that a child is in the corresponding seat if both methods determine that a child is in the corresponding seat, or if the results of the two methods are inconsistent. Otherwise, the system will determine that a child is not in the corresponding seat only if both methods determine that a child is not in the corresponding seat.

[0060] The driver is requested to use method 1 to determine whether there is a child in the corresponding seat, specifically:

[0061] The system sends a voice prompt to the driver requesting confirmation of whether a child is in the corresponding seat. Within a first preset time period, the system receives a signal from the judgment button. If a confirmation signal is received within the first preset time period, it is determined that a child is in the seat corresponding to the confirmation signal. If a denial signal is received within the preset time period, it is determined that no child is in the seat corresponding to the denial signal. If no signal is received after the first preset time period, it is assumed that a child is in the corresponding seat.

[0062] Setting at least two detection methods can largely avoid situations where a child is present but the system determines that no child is present. This embodiment simultaneously sets up three detection methods. First, before starting the vehicle, if the driver determines that a child is present in the relevant seat, the driver directly controls the corresponding window to enter child safety mode. For other undetermined seats, the other two methods are still used for detection. When a child is detected, the corresponding window is then controlled to enter child safety mode. This avoids missed detections and ensures accurate results.

[0063] like Figure 3 As shown, in step S12, determining whether the child is wearing a seatbelt specifically includes the following steps:

[0064] S121. Determine whether a child safety seat is installed on the corresponding vehicle seat. If yes, proceed to step S122; otherwise, proceed to step S123.

[0065] S122. Determine whether the child in the child safety seat is properly fastened with the seat belt. If yes, proceed to step S3; otherwise, proceed to step S13.

[0066] S123. Determine whether the child in the corresponding seat is wearing a seatbelt. If yes, proceed to step S3; otherwise, proceed to step S13.

[0067] The step of determining whether a child is wearing a seatbelt is included because if a child is wearing a seatbelt, it's impossible for the window to fall out. In this case, the corresponding window can be kept in its normal mode to maximize vehicle ventilation. Whether a child is wearing a seatbelt needs to be considered in two scenarios: either a child safety seat is installed in the car, or no child safety seat is installed. In reality, many families with children do not install child safety seats. To account for various situations, a case-by-case determination is necessary, as follows:

[0068] In S122, the specific steps for determining whether a child in a child safety seat is properly secured with a seatbelt are as follows:

[0069] The system determines whether all seatbelt buckles on the child safety seat are properly fastened. If they are, the child is considered to be properly secured; otherwise, they are considered not to be properly secured. This can be achieved by installing sensors on the seatbelt buckles or by using a camera for image recognition.

[0070] Pressure sensors are installed in seats other than the driver's seat, and human age estimation modules are installed in seats other than the driver's seat. In step S123, it is determined whether the child in the corresponding seat is wearing a seat belt, specifically:

[0071] The system obtains the stable pressure increment value of the car seat through pressure sensors. If the stable pressure increment value is less than a preset pressure threshold, it is determined that the child in the car seat is not wearing a seatbelt (regardless of whether the child is actually wearing a seatbelt, it is considered that the child is not wearing a seatbelt, because when a child still needs to use a child safety seat, even if the seatbelt is fastened, it is not safe enough for the child, as it is relatively easy for the child to break free of the seatbelt, which is still very dangerous). If the stable pressure increment value is not less than the preset pressure threshold, the human age estimation module is activated to estimate the child's age. If the child is under 12 years old, it is determined that the child in the car seat is not wearing a seatbelt. If the child is 12 years old or older, the seatbelt locking information is obtained. If the seatbelt is locked, it is determined that the child in the car seat is wearing a seatbelt. If the seatbelt is unlocked, it is determined that the child in the car seat is not wearing a seatbelt. At this time, a voice reminder to fasten the seatbelt is issued. If the seatbelt locks within a second preset time period, it is determined that the child in the car seat is wearing a seatbelt. If the seatbelt is still not locked, it is determined that the child in the car seat is not wearing a seatbelt.

[0072] In step S13, the acquired physical information of the child includes height H, minimum head diameter D, and the preset maximum opening value K is calculated by the following formula:

[0073]

[0074] This embodiment takes into account the child's height H and minimum head diameter D to calculate the maximum opening value, which ensures that the child cannot fall out of the corresponding car window under any circumstances. For example, if the child's height is 120cm and the minimum head diameter is 12cm, then the calculated maximum opening value is... Approximately 13.583, rounded down, K = 13cm.

[0075] The child's height H is written by the driver or estimated through a 3D human body scan using a child recognition camera; the child's minimum head diameter D is estimated based on the height H, weight W, and head size α written by the driver, or estimated through a 3D human body scan using a child recognition camera.

[0076] A relatively simple and accurate method is for the driver or other operator to input the measured height H, weight W, and the head size α judged based on experience into the central control system. The central control system can automatically estimate the minimum diameter of the child's head based on this data. The estimation method can be implemented through a corresponding neural network or by collecting a large amount of data and fitting a corresponding function curve.

[0077] In step S4, the presence status of the child in the vehicle seat is detected in real time to see if there is any change. Specifically:

[0078] If the window corresponding to a seat is in child safety mode, a re-evaluation will be performed every third preset time interval using a method other than method 1. If all re-evaluations determine that there is no child in the seat, the driver will be asked to use method 1 to determine if a child is in the corresponding seat. When the driver confirms that there is no child in the seat, the window will be switched to normal mode. Otherwise, the window will remain in child safety mode. This method allows the window to be switched to normal mode only when operated by the driver, preventing accidental activation by others and potential safety hazards.

[0079] If the window corresponding to the seat is in normal mode, a re-judgment will be performed every third preset time interval using a method other than judgment method 1. If one or more judgment methods re-determine that a child is in the seat, the window will be directly adjusted to child safety mode. Otherwise, the window will remain in normal mode. This method automatically switches the window to child safety mode without driver intervention when it is determined that a child safety mode needs to be switched. During driving, when switching to child safety mode, all windows will be closed (and lowered if necessary, but never to the maximum opening value), maximizing child safety and preventing accidents.

[0080] It should also be noted that the correspondence between the vehicle seat and the vehicle window in this embodiment is as follows:

[0081] The window closest to a child's seat is considered the window corresponding to that seat. If the vehicle has a sunroof, then the sunroof is also considered the window corresponding to that seat, provided it is easily accessible to the child from the corresponding seat.

[0082] Corresponding to the above method, this embodiment also provides a window control system to prevent children from falling out of car windows, including a child detection module and a window control module. The child detection module is used to determine whether there is a child in the vehicle seat before the vehicle starts and while the vehicle is in motion, and sends the relevant detection result to the window control module. The window control module is used to control the opening degree of the window of the corresponding seat according to the detection result, specifically:

[0083] When the determination result is that a child is present, the window corresponding to the seat where the child is present will be controlled to enter child safety mode. In child safety mode, the opening degree of the window corresponding to the seat where the child is present can be adjusted within the preset maximum opening degree value.

[0084] When the determination result is that there are no children, the window corresponding to the seat where there are no children is controlled to be in normal mode. In normal mode, the opening degree of the window corresponding to the seat where there are no children can be adjusted arbitrarily.

[0085] Corresponding to the method, the child detection module includes a detection button, pressure sensors installed in seats other than the driver's seat, child recognition cameras installed in seats other than the driver's seat, a human age estimation module, and a voice reminder module. These modules, along with the window control module, can be bound to the vehicle operating system to achieve corresponding information collection, processing, and transmission functions. Various adjustments can be made considering implementation difficulty, cost, and vehicle aesthetics. This embodiment does not limit the appearance, structure, or installation location of these modules, as long as they can achieve the corresponding functions.

[0086] In summary, the vehicle window control method and system for preventing children from falling out of car windows provided by the embodiments of the present invention can automatically adjust the adjustment mode of the corresponding vehicle window according to whether there is a child in the vehicle seat. Different adjustment modes have different opening adjustment ranges, and can ensure the safety of children when the vehicle is started and during the vehicle's operation. Even if there is no adult accompanying the child in the back seat, the rear window of the vehicle can be adjusted to a certain opening to ensure vehicle ventilation.

[0087] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.

A method for controlling vehicle windows to prevent children from falling out of them, as described in claim 6, characterized in that: Children's height H The data is written by the driver or estimated through a 3D human body scan using the child recognition camera. The smallest diameter of a child's head D According to the height written by the driver H ,weight W And the degree of head size α It can be estimated, or estimated by performing a 3D human body scan using the child recognition camera.

8. A method for controlling a car window to prevent children from falling out of it, as described in claim 7, is characterized in that... In step S4, the presence status of the child in the vehicle seat is detected in real time to see if there is a change, specifically: If the window corresponding to the seat is in child safety mode, the system will re-evaluate the situation every third preset time period using a method other than judgment method 1. If all judgment methods re-evaluate that there is no child in the seat, the system will request the driver to use judgment method 1 to determine whether there is a child in the corresponding seat. When the driver confirms that there is no child in the seat by operating the judgment case, the window will be adjusted to normal mode. Otherwise, the window will remain in child safety mode. If the window corresponding to the seat is in the normal mode, the system will re-evaluate the situation every third preset time period using a method other than judgment method 1. If one or more judgment methods re-evaluate that there is a child in the seat, the window will be directly adjusted to the child safety mode. Otherwise, the window will remain in the normal mode.

9. A vehicle window control system based on the vehicle window control method for preventing children from falling out of car windows according to any one of claims 1 to 8, characterized in that: This includes a child detection module and a window control module. The child detection module determines whether a child is in the vehicle seat before starting the vehicle and while the vehicle is in motion, and sends the determination result to the window control module. The window control module controls the opening degree of the corresponding seat window based on the determination result. Specifically: When the determination result is that a child is present, the window corresponding to the seat where the child is present is controlled to be in child safety mode. In child safety mode, the opening degree of the window corresponding to the seat where the child is present is adjustable within a preset maximum opening degree value. When the determination result is that there are no children, the window corresponding to the seat where there are no children is controlled to be in normal mode. In the normal mode, the opening degree of the window corresponding to the seat where there are no children can be adjusted arbitrarily.
