Description

Technical Field

[0001] This invention relates to the field of child vehicle technology, and in particular to a method and system for adjusting a capacitance detection mechanism in a child vehicle, and a method and apparatus for detecting a forgotten child in a child seat. Background Technology

[0002] 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.

[0003] Therefore, the current common practice is to install capacitive thin-film sensors in child seats. These sensors detect the presence of a child by checking if the capacitance between the child and the sensor exceeds a preset value, thus preventing children from being forgotten in the car. However, a problem exists: clothing can change with the seasons, leading to variations in the distance between the child and the sensor. If the sensor's plates are in a fixed position or the contact area is fixed, and the goal is to detect children year-round (e.g., using a winter season with a preset capacitance value for a child in the seat), there's a possibility of misidentifying objects as children in summer, resulting in a poor user experience.

[0045] 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.

[0046] 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.

[0047] 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 capacitor plate 200 of the capacitive sensor in the middle 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 capacitor plate 200 of the capacitive sensor can form a contact with the child 300. Figure 3The parallel-plate capacitor model is shown. The capacitance sensor can identify whether a child is in the child seat by detecting the capacitance value between the capacitor plates 200 and the child 300. 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 in the vehicle.

[0048] In related technologies, the preset value for determining the presence of a child is a fixed value. However, due to varying ambient temperatures and the thickness of children's clothing, the distance between the child and the electrode plates on the seat will differ. Therefore, to detect children year-round, a lower preset value (e.g., a winter detection value) is used. While this may detect a child in the seat in winter, it may falsely detect other conductive objects as children in summer, leading to frequent misjudgments and a poor user experience.

[0049] Figure 4 This is a block diagram of the adjustment system for the capacitance detection mechanism in a child vehicle according to an embodiment of the present invention. Figure 4 As shown, the adjustment system includes: a vehicle body 100 and a capacitive sensor located in the vehicle body 100, the capacitive sensor including at least one capacitor plate 40.

[0050] Detection module 10 is used to detect environmental parameters;

[0051] Controller 20, connected to detection module 10, is used to generate execution instructions based on environmental parameters. The execution instructions include access quantity parameters and / or first spacing parameters.

[0052] The actuator 30 is connected to the controller 20 and at least one capacitor plate 40 respectively. It is used to adjust the number of capacitor plates that have been connected to the capacitor sensor to measure the capacitance value according to the access quantity parameter. It is also used to adjust the distance between the capacitor plate that has been connected to the capacitor sensor to measure the capacitance value and the bearing surface of the carrier body 100 according to the first spacing parameter.

[0053] Understandably, if the number of capacitor plates connected to the capacitive sensor and the first spacing remain unchanged, then the preset value A stored in the controller 20 must be the minimum value that the capacitive sensor can detect. For example, if the relative area between the child and the capacitive sensor is fixed, the detection value of the capacitive sensor will differ depending on the thickness of the child's clothing. For instance, when the child's clothing is thin (e.g., open-crotch shorts), the detection value of the capacitive sensor is A1; when the child's clothing is of medium thickness (e.g., fleece trousers), the detection value is A2; and when the child's clothing is thick (e.g., down pants), the detection value is A3. In this case, A1>A2>A3. In order for the capacitive sensor to detect the presence of a child, A needs to be less than or equal to A3. This would result in a false alarm if the child's clothing is the thinnest and some items are scattered on the seat (where the detection value might be greater than A3).

[0054] If, in order to avoid misjudgment, the preset value A in controller 20 is set to A1 or less than A1 and greater than A2, then it becomes impossible to judge the results of A2 and A3.

[0055] Based on the above, in this embodiment of the invention, the preset value in the controller 20 is set to A = A1 or slightly less than A1 to avoid misidentifying an item located in the vehicle body as a child. In scenarios where A2 and A3 were previously detected, by changing the detection capability of the capacitive sensor, it is also possible to achieve A or higher, thus enabling the determination of whether a child is in the vehicle body.

[0056] It should be noted that in the above embodiments, the number of at least one capacitor plate 40 can be M, for example M=4, such as... Figure 5 and Figure 6 As shown, it includes a first capacitor plate 41, a second capacitor plate 42, a third capacitor plate 43, and a fourth capacitor plate 44.

[0057] The four capacitor plates can be connected and measured according to actual needs to adjust the contact area with the child. The positions of the four capacitor plates are... Figure 6 The direction of the arrow shown is adjustable to regulate the distance between the capacitor and the child. In other embodiments, the contact area can also be adjusted by controlling the four capacitor plates as a whole to be perpendicular to... Figure 6 This is achieved by moving within a plane in the direction of the arrow shown.

[0058] Whether the capacitor plates are connected to the capacitance sensor for measurement can be controlled by relevant circuitry, such as controlling whether to apply a corresponding voltage to the capacitor plates. The position of the capacitor plates can be adjusted using an electric push rod or other electric telescopic rod. In one embodiment, the capacitance sensor can be equipped with a cavity to house the capacitor plates and the aforementioned electric telescopic rod.

[0059] In this embodiment of the invention, during the preset value determination stage, the initial state of the capacitor plates in the capacitive sensor can be such that 25% of the area of ​​the bearing surface is connected (taking four as an example, i.e., one is connected, and the number connected is the first quantity). The four capacitor plates are positioned relatively far from the bearing surface of the carrier body 100. Then, a child wearing thin clothing is placed inside the carrier body 100, and the positions of the four capacitor plates are uniformly adjusted towards the bearing surface of the carrier body 100. When a detection value is obtained, a control group can be established. For example, one adjustment is made towards the bearing surface of the carrier body 100 with the child as the object, and another adjustment is made towards the bearing surface of the carrier body 100 with an object (such as an apple or bottled water). When the detection value of the capacitive sensor with the child as the object is N times the detection value of the capacitive sensor with the object as the object, the adjustment stops. This position is recorded as the reference position of the four capacitor plates, and the detection value of the capacitive sensor with the child as the object, or a value slightly less than this detection value, is used as the preset value A. It should be noted that N here is a positive number, which can be determined based on the spatial range of the cavity of the actual capacitive sensor. Furthermore, in the control group example above, the relative contact area between the child and the capacitor plates is generally larger than the relative contact area between the object and the capacitor plates. This allows for the filtering out of some objects while still detecting children. In actual product manufacturing, the reference positions of the four capacitor plates can be used as the location of the lower surface.

[0060] In one embodiment, after determining the reference position and preset value A, a child wearing moderate clothing thickness can be placed in the carrier body 100. At this time, by increasing the number of capacitor plates (e.g., to 50% of the area of ​​the bearing surface), the detected capacitance value is A, and this number is recorded as a second value. Alternatively, by shortening the spacing between the capacitor plates, the detected capacitance value is A, and this spacing is recorded as a second distance. Alternatively, by shortening the spacing between the capacitor plates and adjusting by increasing the number of capacitor plates, when the adjustment number is determined, the detected capacitance value is A, and the spacing is determined accordingly.

[0061] Similarly, in one embodiment, after determining the reference position and the preset value A, a child wearing thick clothing can be placed in the carrier body 100. At this time, by increasing the number of capacitor plates (for example, to 100% of the area of ​​the bearing surface), the detected capacitance value is A, and this number is recorded as the third quantity. Alternatively, by shortening the spacing between the capacitor plates, the detected capacitance value is A, and this spacing is recorded as the third distance. Alternatively, by shortening the spacing between the capacitor plates and adjusting by increasing the number of capacitor plates, when the adjustment quantity is determined, the detected capacitance value is A, and the spacing is determined accordingly.

[0062] In practical applications, the preset value A obtained from the above experiments, as well as the adjustment amounts (number and / or distance) based on different clothing thicknesses, can be defined using the adjustment reference (25% of the area and the reference position). For example, taking four capacitor plates as an example, if the clothing thickness is thin, the number of plates connected is one, and the first distance between the reference position and the bearing surface is H1. If the clothing thickness is medium, the number of plates connected is two, or the first distance is the difference between H1 and the second distance, or it can be a relationship between the first distance and the number of plates connected. If the clothing thickness is thick, the number of plates connected is four, or the first distance is the difference between H1 and the third distance, or it can be a relationship between the first distance and the number of plates connected.

[0063] This establishes a correspondence between environmental parameters, clothing thickness, adjustment parameters, and execution commands. Specifically, environmental parameters correspond to clothing thickness, clothing thickness corresponds to adjustment parameters, and adjustment parameters correspond to execution commands. This, in turn, creates a correspondence between environmental parameters and execution commands. This correspondence can be pre-stored in the controller 20, and then the corresponding execution command is issued based on the environmental parameters. The actuator 30 adjusts according to the execution command.

[0064] It should be noted that the above examples are merely illustrative of the process principles, and the corresponding data do not constitute a limitation on the scope of protection of this invention.

[0065] Therefore, by detecting environmental parameters, the thickness of clothing can be determined. Then, based on the above-mentioned reference position and preset value A, the position and / or number of the four capacitor plates can be adjusted in advance, and the detection can be carried out when it is necessary to detect whether there is a child in the seat.

[0066] Optionally, the detection module includes a temperature detection module, and the environmental parameters include temperature parameters;

[0067] The temperature parameters include a first temperature, a second temperature, and a third temperature. The first temperature is within a first temperature range, the second temperature is within a second temperature range, and the third temperature is within a third temperature range. 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.

[0068] The controller is used to generate a first execution instruction based on a first temperature, a second execution instruction based on a second temperature, and a third execution instruction based on a third temperature.

[0069] It should be noted that children wear thicker clothing in the first temperature range, medium-thickness clothing in the second temperature range, and thinner clothing in the third temperature range.

[0070] Therefore, by detecting the temperature and determining its range, corresponding execution commands can be issued. For example, temperature can be measured using an infrared temperature sensor or obtained from weather forecasts.

[0071] Optionally, the detection module includes a seasonal parameter detection module, and the environmental parameters include spring environmental parameters, summer environmental parameters, autumn environmental parameters and winter environmental parameters;

[0072] The controller is used to generate a first execution instruction based on winter environmental parameters, a second execution instruction based on spring or autumn environmental parameters, and a third execution instruction based on summer environmental parameters.

[0073] It should be noted that children wear thicker clothing in winter, moderately thicker clothing in spring or autumn, and thinner clothing in summer.

[0074] Therefore, by detecting seasonal parameters and determining which season the current period falls within, corresponding execution commands can be issued. For example, the current solar term can be used to determine the four seasons (spring, summer, autumn, and winter), or the seasonal parameters can be manually entered by the user. When the four seasons are automatically identified through the solar term, for example, if the current solar term is between the Beginning of Spring and Grain Rain, it is spring; if the current solar term is between the Beginning of Summer and Great Heat, it is summer; if the current solar term is between the Beginning of Autumn and Frost's Descent, it is autumn; and if the current solar term is between the Beginning of Winter and Great Cold, it is winter.

[0075] Optionally, when the execution instruction includes an access quantity parameter, the access quantity adjusted by the executor under the first execution instruction is greater than the access quantity adjusted under the second execution instruction; and the access quantity adjusted by the executor under the second execution instruction is greater than the access quantity adjusted under the third execution instruction.

[0076] In one embodiment, the number of access points can be adjusted individually, thus enabling... Figure 6 There is no need to set up activity space in the direction of the arrow shown, which saves space.

[0077] Optionally, when the execution instruction is the first spacing parameter, the first spacing adjusted by the actuator under the first execution instruction is smaller than the first spacing adjusted under the second execution instruction; and the first spacing adjusted by the actuator under the second execution instruction is smaller than the first spacing adjusted under the third execution instruction.

[0078] In one embodiment, the first spacing can be adjusted individually, which reduces the number of capacitor plates required and saves materials.

[0079] In another embodiment, the relationship between the first spacing and the number of connections can be adjusted, taking into account both the utilization of capacitor plate materials and space.

[0080] Optionally, the adjustment system also includes: a month age detection module for obtaining the child's month age;

[0081] The controller is connected to the age detection module and is used to generate correction instructions when the child's age is less than the preset age.

[0082] When the execution instruction includes an access quantity parameter, the correction instruction includes an access quantity correction parameter, which is used to correct the access quantity parameter. And / or, when the execution instruction includes a first spacing parameter, the correction instruction includes a first spacing correction parameter, which is used to correct the first spacing parameter.

[0083] Understandably, the preset age is 9 months. When the child is less than 9 months old, a cotton pad is needed, while when the child is older than 9 months old, a cotton pad is no longer needed. Therefore, the vehicle body 100 that does not use a cotton pad can be adjusted according to the aforementioned content.

[0084] For the part using cotton pads, another test can be conducted based on the thickness of the child's clothing to obtain the correction amount. This correction amount is then used to obtain the parameters without cotton pads based on environmental parameters in practice. After making corrections using this correction amount, the execution command is then issued.

[0085] For example, when adjusting by the number of access points, if the number of access points without padding is W based on environmental parameters, then the correction amount for the number of access points with padding can be added to W as the access point parameter. When adjusting by the first spacing, if the first spacing without padding is H based on environmental parameters, then the correction amount for the first spacing with padding can be added to H as the first spacing parameter. Similarly, the relationship between the number of access points (corresponding area) with padding and the first spacing can also be corrected based on the relationship between the number of access points without padding (corresponding area) and the first spacing.

[0086] Figure 7 This is a flowchart illustrating the adjustment method for the capacitance detection mechanism in a child vehicle according to an embodiment of the present invention. This method is implemented based on the adjustment system of any embodiment of the present invention, such as... Figure 7 As shown, the adjustment method includes:

[0087] S101, Obtain environmental parameters;

[0088] S102, Generate execution instructions based on environmental parameters;

[0089] S103, control the actuator to execute the execution command to adjust the number of capacitor plates connected to the capacitance sensor to measure the capacitance value and / or the distance between the capacitor plates connected to the capacitance sensor to measure the capacitance value and the bearing surface of the vehicle body.

[0090] Among these, environmental parameters can be determined based on temperature or seasonal solar terms. Seasonal solar terms can be obtained from weather forecasts or calendars, while temperature can be obtained from weather forecasts or temperature sensors.

[0091] After acquiring environmental parameters, the thickness of the child's clothing can be determined. Based on this clothing thickness, the number of vehicles to be connected and / or the first spacing can be determined, and an execution command can be issued. After the execution command is adjusted, the presence of a child can be detected once the child is inside the vehicle. This method avoids misjudging certain items after they are placed on the vehicle and can also detect children. This method embodiment achieves the technical effects of the system embodiment. For other details, please refer to the system embodiment; they will not be repeated here.

[0093] S201, the capacitor plate of the capacitance sensor in the child seat is adjusted using the adjustment method of the capacitance detection mechanism in the child vehicle according to the embodiment of the present invention.

[0094] The beneficial effects and related explanations of this step can be found in the adjustment process of the aforementioned adjustment method for the capacitance detection mechanism in child vehicles, which will not be repeated here.

[0095] S202, determine whether the detection trigger condition has been met.

[0096] Optionally, determining whether the detection trigger condition has been met includes: determining whether the distance between the child seat and the user terminal has reached the alarm distance limit, and determining that the detection trigger condition has been met when the alarm distance limit has been reached.

[0097] S203, after the triggering condition is met, determines whether there is a child in the child seat based on the detection value of the adjusted capacitive sensor.

[0098] In other words, certain triggering conditions need to be met to detect whether a child is in the child seat, avoiding frequent detection. Specifically, detecting the presence of a child in the child seat can be triggered when the distance between the child seat and the user terminal reaches the alarm distance limit. The specific triggering conditions can be set according to actual needs.

[0099] S204: When the detected value is greater than or equal to the preset value, it is determined that there is a child in the child seat, and a forgetting reminder is sent to the user.

[0100] The reminders can be sent via sound messages such as buzzers or loudspeakers, or via text messages or voice messages.

[0104] The reminder module 203 is used to send a forgetting reminder to the user when there is a child in the child seat.

Therefore, the capacitance sensor can be adjusted according to environmental parameters, ensuring that the detection value of the capacitance sensor is greater than or equal to a preset value throughout the year, avoiding situations where the detection value of the capacitance sensor does not reach the preset value due to changes in the child's clothing or age, thus preventing misjudgments.
