[0002] This patent application claims priority to Chinese Patent Application No. 2024105165201, filed on April 26, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This invention relates to the field of child car seat technology, and in particular to a method for adjusting a capacitance detection mechanism in a child vehicle, a method, device, equipment, and medium for detecting a forgotten child in a child seat. Background Technology

[0004] Car seats are typically designed for adults, so child safety seats are necessary when children are traveling alone to ensure their safety. However, if a child is forgotten in a car, the enclosed environment or other accidents can still cause harm, even irreversible damage.

[0005] Therefore, the current common practice is to install capacitive thin-film sensors in child seats. The presence of a child in the seat is determined by whether the capacitance between the child and the sensor exceeds a preset value, thus preventing children from being forgotten in the car. However, this method has problems. Children's contact area with the sensor varies depending on their age; and clothing changes with the seasons, leading to variations in the distance between the child and the sensor. Consequently, the capacitance value between the child and the sensor is dynamically changing and varies considerably. Using fixed-value judgment methods in related technologies often results in false identification, degrading the user experience. Summary of the Invention

This allows the capacitance detection limit to be adjusted according to the child's actual situation, thereby enabling detection with a varying capacitance detection limit. This solves the problem in related technologies where a fixed capacitance detection limit leads to misidentification of objects as children or the inability to identify children despite their presence.

[0074] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0075] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0076] Figure 1 This is a schematic diagram of the structure of the child vehicle provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of the capacitive sensor in a child vehicle provided in an embodiment of the present invention. In this embodiment, the child vehicle is a child seat. Figure 1 and Figure 2 As shown, the child seat is installed in the car seat. Figure 2 The electrode plate 200 of the capacitive sensor can be configured in Figure 1 The seat cushion 100 is located in the child seat. When a child 300 is in the child seat, the electrode plate 200 of the capacitive sensor can form a contact with the child 300. Figure 3The parallel-plate capacitor model shown is illustrated. The capacitance sensor can identify whether a child is in the child seat by detecting the sum of the capacitance between the electrode plate 200 and the child 300, and the capacitance between the electrode plate 200 and ground. For example, if a child is in the child seat, the child seat can communicate with the driver's portable terminal, such as via Bluetooth. When the distance between the driver and the vehicle exceeds the Bluetooth communication range, a reminder message is sent to the driver's portable terminal, reminding them that the child is still in the car, thus preventing the child from being forgotten.

[0077] In related technologies, the capacitance value of the electrode plate 200 to ground is generally set to the capacitance detection limit. This makes the capacitance sensor very sensitive. Even if a bottle of water is placed on the child seat, it will be detected as a child in the child seat, triggering frequently. This means that users may often need to return to the car to check after leaving, causing some inconvenience to users.

[0078] Figure 4 This is a flowchart of the adjustment method for the capacitance detection mechanism in a child vehicle according to an embodiment of the present invention, as shown below. Figure 4 As shown, it includes:

[0079] S101, Obtain the adjustment parameters;

[0080] The adjustment parameters include the clothing index and / or age parameters.

[0081] In one embodiment, the adjustment parameters can be manually input by the user. For example, a corresponding input module, such as a button module, touch screen, or voice module, can be set up on the child seat for the user to input the adjustment parameters. Alternatively, a corresponding input module, such as a button module, touch screen, or voice module, can be set up on a terminal (mobile phone, tablet, smartwatch, in-vehicle terminal) that can communicate with the child seat for the user to input the adjustment parameters, and then the adjustment parameters are obtained through communication.

[0082] In another embodiment, adjustment parameters can also be acquired automatically. For example, the controller can be set to automatically acquire parameters at specific times. For instance, the clothing index can be obtained based on seasonal or temperature parameters. Temperature parameters can be acquired through electronic devices such as temperature sensors, while seasonal parameters can be acquired through weather forecast apps. The age parameter can be manually entered during the first use, and the time can be automatically recorded, allowing the child's age to be acquired automatically in subsequent uses.

[0083] S102, adjust the capacitance detection limit of the capacitance detection mechanism according to the adjustment parameters.

[0084] It should be noted that in related technologies, the capacitance detection limit is usually set to a fixed value, and this fixed value is preset in the controller as a comparison benchmark. For example, when the actual detection value is greater than the fixed value, it is considered that there is a child, and when the actual detection value is less than the fixed value, it is considered that there is no child.

[0085] Understandably, the thickness of a child's clothing directly affects the distance between the child and the electrode plates of the capacitive sensor, while the child's age directly affects the relative area between them, resulting in a large range of variations in the detected capacitance value. If the capacitance detection limit is fixed, for example, set to a very small value, false triggering is likely; if the limit is increased, when the actual capacitance between the child and the sensor's electrode plates is small, it may fall below the fixed value and be difficult to detect. Therefore, a fixed capacitance detection limit cannot accommodate a large range of variations in the detected capacitance value.

[0086] Furthermore, this invention adjusts the capacitance detection limit of the capacitance detection mechanism (such as the controller that serves as the judgment mechanism in the capacitance detection mechanism) by influencing the clothing index and / or age parameter of the capacitance. This can adapt to a wide range of changes in the detected capacitance value, avoid misidentification or failure to identify, and can be achieved through algorithmic adjustment, avoiding improvements to the hardware entity.

[0087] In one embodiment, adjusting the capacitance detection limit of the capacitance detection mechanism according to the adjustment parameters includes: obtaining a preset correspondence, wherein the preset correspondence is a correspondence between the adjustment parameters and the capacitance detection limit; and adjusting the capacitance detection limit of the capacitance detection mechanism according to the adjustment parameters and the preset correspondence.

[0088] The preset correspondence can be a curve, a table, or other correspondences, and the preset correspondence can be obtained in advance through experiments or model training.

[0089] Optionally, S102 adjusts the capacitance detection limit of the capacitance detection mechanism according to the adjustment parameters, including:

[0090] The capacitance detection limit of the capacitance detection mechanism is adjusted according to a single adjustment parameter.

[0091] In one embodiment, the capacitance detection limit of the capacitance detection mechanism can be adjusted according to a single adjustment parameter and a corresponding preset correspondence. When the adjustment parameter is the clothing index, the preset correspondence can be the correspondence between the clothing index and the capacitance detection limit. Adjusting the capacitance detection limit of the capacitance detection mechanism according to a single adjustment parameter and a corresponding preset correspondence means adjusting it according to the clothing index and the corresponding correspondence.

[0092] When the adjustment parameter is the age parameter, the preset correspondence can be the relationship between the age parameter and the capacitance detection limit. The capacitance detection limit of the capacitance detection mechanism is adjusted according to a single adjustment parameter and the corresponding preset correspondence, that is, adjusted according to the age parameter and this correspondence.

[0093] It should be noted that the preset correspondences can be obtained through multiple trials or by training a neural network model.

[0094] Optionally, the adjustment parameter in adjusting the capacitance detection limit of the capacitance detection mechanism according to the adjustment parameter is the clothing index:

[0095] When the clothing index is the first clothing index, the adjustment capacitor detection limit is the first limit value;

[0096] When the clothing index is the second clothing index, the adjustment capacitor detection limit is the second limit value;

[0097] When the clothing index is the third clothing index, the adjustment capacitor detection limit is the third limit; wherein, the clothing thickness of the first clothing index is greater than the clothing thickness of the second clothing index, the clothing thickness of the second clothing index is greater than the clothing thickness of the third clothing index; the first limit is greater than the second limit, and the second limit is greater than the third limit.

[0098] Understandably, in establishing the correspondence between clothing index and capacitance detection limit during experiments or model training, the child can be the same person, and the clothing index can be manually input. For example, the first capacitance value is obtained when the child wears thin single-layer trousers, the second capacitance value is obtained when the child wears medium-thickness fleece trousers, and the third capacitance value is obtained when the child wears thick cotton trousers. This establishes the corresponding correspondence between the clothing index and capacitance value. Since the first capacitance value is greater than the second capacitance value, and the second capacitance value is greater than the third capacitance value, the capacitance detection limit for thicker clothing is less than the capacitance detection limit for medium-thickness clothing, and the capacitance detection limit for medium-thickness clothing is less than the capacitance detection limit for thinner clothing.

[0099] Among them, the first limit under the first clothing index can be the third capacitance value, the second limit under the second clothing index can be the second capacitance value, and the third limit under the third clothing index can be the first capacitance value.

[0100] It should be noted that by training a large model or conducting multiple trials, such as tracking a child's clothing index at different times and collecting the corresponding capacitance values, the capacitance values ​​of the child under different clothing thicknesses can be obtained. By tracking data from multiple children, the correspondence between clothing index and capacitance values ​​can be obtained.

[0101] In actual operation, the clothing index can be manually entered or obtained from weather forecasts such as long-sleeved shirts, sweaters, and down jackets. For example, down jackets are the first clothing index, sweaters are the second clothing index, and long-sleeved shirts are the third clothing index. Once the clothing index is obtained, the capacitance detection limit can be adjusted according to the clothing index and the corresponding relationship.

[0102] Therefore, since the detected capacitance value decreases when wearing thicker clothing, the capacitance detection limit can be lowered; conversely, since the detected capacitance value increases when wearing thinner clothing, the capacitance detection limit can be raised. Furthermore, the clothing index generally doesn't fluctuate significantly over the next week or two, allowing for the setting of appropriate reminder frequencies based on a week or two.

[0103] Optionally, the adjustment parameters are obtained, including:

[0104] Obtain seasonal parameters;

[0105] The clothing index is determined based on seasonal parameters.

[0106] It should be noted that the seasonal parameter refers to the four seasons: spring, summer, autumn, and winter. This can be determined by the current solar term or by the user manually entering the seasonal parameter. When the seasons are automatically identified by the solar term, for example, if the current solar term is between the Beginning of Spring and Grain Rain, it is spring; if it is between the Beginning of Summer and Great Heat, it is summer; if it is between the Beginning of Autumn and Frost's Descent, it is autumn; and if it is between the Beginning of Winter and Great Cold, it is winter.

[0107] Optionally, the clothing index can be determined based on seasonal parameters, including:

[0108] When the seasonal parameter is spring or autumn, the clothing index is determined as the second clothing index;

[0109] When the seasonal parameter is summer, the clothing index is determined to be the third clothing index;

[0110] When the seasonal parameter is winter, the clothing index is determined as the first clothing index.

[0111] In spring and autumn, the children's clothing index is the same, so the capacitance detection limit can be set to the capacitance detection limit corresponding to the second clothing index. In summer, the children's clothing index is lower, so the capacitance detection limit can be set to the capacitance detection limit corresponding to the third clothing index. In winter, the children's clothing index is higher, so the capacitance detection limit can be set to the capacitance detection limit corresponding to the first clothing index.

[0112] Optionally, the adjustment parameters are obtained, including:

[0113] Obtain temperature parameters;

[0114] Determine the clothing index based on temperature parameters.

[0115] For example, ambient temperature can be obtained through weather forecasts, temperature sensors, or thermometers. The level of ambient temperature affects the child's clothing index, and thus, the capacitance detection limit can be adjusted according to the ambient temperature.

[0116] Optionally, the clothing index can be determined based on temperature parameters, including:

[0117] When the temperature parameter is within the first temperature range, the clothing index is determined as the first clothing index;

[0118] When the temperature parameter is in the second temperature range, the clothing index is determined to be the second clothing index;

[0119] When the temperature parameter is in the third temperature range, the clothing index is determined to be the third clothing index;

[0120] The upper limit of the first temperature range is less than the lower limit of the second temperature range, and the upper limit of the second temperature range is less than the lower limit of the third temperature range.

[0121] For example, in spring or autumn, the temperature varies greatly in the morning, noon and evening. The clothing index should be thicker in the morning and evening than at noon. Therefore, when traveling in the morning or evening, the capacitance detection limit can be smaller than when traveling at noon.

[0122] Optionally, the adjustment parameter in adjusting the capacitance detection limit of the capacitance detection mechanism according to the adjustment parameter is an age parameter;

[0123] When the age parameter is the first month, the adjustment capacitor detection limit is the fourth limit.

[0124] When the age parameter is the second month, the adjustment capacitor detection limit is the fifth limit.

[0125] Among them, the first month of age is greater than the second month of age, and the fourth limit is greater than the fifth limit.

[0126] It is understandable that, generally speaking, the relative area between a younger infant and the electrode plate of the capacitance sensor is smaller, while the relative area between a younger infant and the electrode plate of the capacitance sensor is larger. Therefore, the capacitance detection limit for a younger infant is smaller than that for a younger infant.

[0127] In one embodiment, when the child's age is less than or equal to a preset age (e.g., 9 months), the child seat needs to use a cotton pad to better support and wrap the child. The use of the cotton pad increases the distance between the child and the electrode plate of the capacitive sensor. Therefore, with the addition of the cotton pad, the child seat can be adjusted according to the child's age under the same reference. Alternatively, without the addition of a cotton pad, the seat can be adjusted according to the child's age under the same reference.

[0128] In another embodiment, the maximum value of the capacitance detection limit of the capacitance detection mechanism with added pads can be less than the minimum value of the capacitance detection limit of the capacitance detection mechanism without added pads.

[0129] Optionally, adjusting the capacitance detection limit of the capacitance detection mechanism according to the adjustment parameters includes: acquiring at least two of the adjustment parameters; and determining the priority of different adjustment parameters.

[0130] Adjust the capacitance detection limit of the capacitance detection mechanism according to the priority order of the adjustment parameters.

[0131] In other words, the capacitance detection limit of the capacitance detection mechanism is adjusted based on both the age parameter and the clothing index.

[0132] Optionally, at least two of the adjustment parameters are acquired; determining the priority of the different adjustment parameters includes:

[0133] Two adjustable parameters are obtained: age in months and clothing index.

[0134] The age parameter has a higher priority than the clothing index;

[0135] Adjusting the capacitance detection limit of the capacitance detection mechanism according to the priority order of the adjustment parameters includes:

[0136] The adjustment range of the capacitance detection limit of the capacitance detection mechanism is determined based on the age parameter.

[0137] The capacitance detection limit of the capacitance detection mechanism is adjusted according to the clothing index and the adjustment range of the capacitance detection limit.

[0138] Since the child's age in months determines the capacitance detection limit adjustment range of the capacitance detection mechanism, the age parameter is given the highest priority. After obtaining the child's age in months, it can be determined whether a cushion is placed in the child seat. If a cushion is placed, the capacitance detection limit is adjusted within a first range; if no cushion is placed, the capacitance detection limit is adjusted within a second range. In one embodiment, the upper limit of the first range is lower than the lower limit of the second range.

[0139] Therefore, after determining the adjustment range of the capacitance detection limit through the age parameter, it can be further adjusted through the clothing index, thus narrowing the adjustment range.
