Description

Technical Field

[0001] This invention relates to the field of automotive safety monitoring technology, and in particular to a child anti-pinch control method, device, and equipment for car seats. Background Technology

[0002] With the increasing demand for intelligent and comfortable vehicles, traditional manual seats have gradually been upgraded to advanced electric seats with multiple functions. However, this process has led to an increased risk of accidents where occupants, especially children, get caught in seat gaps or the gap between the seat back and the vehicle body.

[0003] Currently, existing solutions for anti-pinch seats in the automotive industry have the following shortcomings: Motor current / Hall effect anti-pinch solutions are reactive, requiring a clamping force sufficient to harm a child to trigger a response, thus failing to provide preventative protection; Seat cushion pressure sensor solutions have blind spots in weight recognition, failing to effectively detect low-weight infants, and the detection area is limited to the center of the seat cushion, resulting in numerous coverage dead zones; Conductive rubber anti-pinch strip solutions, while sensitive to triggering, are expensive, limiting their application to localized areas and preventing all-around protection. Furthermore, they are prone to damage and breakage during use due to leather covering, compression, aging, and repeated bending, leading to poor long-term reliability. Summary of the Invention

[0004] This invention provides a child anti-pinch control method, device, and equipment for car seats, so as to precisely execute anti-pinch control during the use of intelligent electric seats.

[0005] To alleviate the above-mentioned technical problems, the technical solution provided by the present invention is as follows: A first aspect of the present invention provides a child anti-pinch control method for a car seat, comprising: The detection signals of the seat cushion area and the backrest area of ​​the car seat were acquired respectively; In response to receiving a motion adjustment command to control the car seat, an active anti-pinch strategy or a semi-active anti-pinch strategy is executed. Among them, the active anti-pinch strategy includes: Before the motion adjustment command is executed, the presence of a target object in the seat cushion area and / or backrest area is determined based on the detection signal. If the presence of a target object is determined, the execution of the motion adjustment command is restricted or prohibited. Semi-active anti-pinch strategies include: During the process of executing motion adjustment commands to drive the car seat to move, changes in detection signals are monitored in real time to control the actuators used to drive the car seat to perform anti-pinch actions, which are used to adjust the movement conditions of the car seat.

[0006] As a preferred implementation, restricting or prohibiting the execution of motion adjustment commands includes: Determine if the motion adjustment command matches the preset linkage adjustment mode; When the motion adjustment command matches the preset linkage adjustment mode, the preset linkage adjustment mode is prohibited from being executed when a target object is identified in the backrest area.

[0007] As a preferred implementation, restricting or prohibiting the execution of motion adjustment commands includes: Determine if the motion adjustment command matches the preset linkage adjustment mode; When the motion adjustment command matches the preset linkage adjustment mode, if it is determined that there is a target object in the seat cushion area but no target object in the backrest area, the adjustment of the car seat backrest is restricted so that the angle between the car seat backrest and the car seat cushion does not exceed the preset angle.

[0008] In one preferred embodiment, controlling the actuator used to drive the car seat to perform an anti-pinch action includes: In response to changes in the detection signal indicating the presence of a target object in the backrest or seat area, the actuator is controlled to perform a reverse movement or stop the movement.

[0009] As a preferred embodiment, controlling the actuator to perform reverse motion or stop motion includes: In response to a change in the detection signal indicating the presence of a target object in the backrest area, the actuator is controlled to move in the opposite direction. In response to changes in the detection signal indicating the presence of a target object in the seat cushion area, the control actuator stops moving.

[0010] As a preferred embodiment, the method further includes: When an action adjustment command matches a manual adjustment command, the execution priority of the manual adjustment command is set to be higher than the processing priority of the preset linkage adjustment mode.

[0011] As a preferred embodiment, the method further includes: In response to receiving an action adjustment command, an authorization request is sent to the vehicle's central control unit so that the central control unit displays a confirmation interface on the vehicle's display screen; After receiving the authorization confirmation signal from the central control unit, the step of determining whether the target object exists is performed. The authorization confirmation signal is generated by the central control unit in response to the user's confirmation input on the confirmation interface.

[0012] As a preferred embodiment, the method further includes implementing a passive anti-pinch strategy: Collect the motor operating parameters of the actuator, including the motor's no-Hall ripple voltage, motor Hall signal, or bus current signal; When it is determined that there is no target object in both the seat cushion area and the backrest area, when the motor operating parameters reach the preset load stall condition, the control actuator will stop the machine in an emergency or move in the reverse direction. The preset load stall conditions include: the rise of the bus current signal exceeds the preset current change threshold, or the motor speed obtained based on the motor Hall signal or the motor no Hall ripple voltage decreases and falls below the preset speed threshold.

[0013] As a preferred implementation, the preset linkage adjustment mode includes at least: One-click folding mode, one-click lay-down mode, or zero-gravity linkage mode can be triggered via the vehicle's infotainment system or mobile application.

[0014] As a preferred embodiment, the method further includes: When the execution of motion adjustment commands is restricted or prohibited, or when the actuator performs an anti-pinch action, a voice or sound and light prompt signal is output simultaneously.

[0015] A second aspect of the present invention provides a child anti-pinch control device for a car seat, comprising: The detection module is used to acquire detection signals from the seat cushion area and the backrest area of ​​the car seat, respectively. Actuators used to drive the movement of car seats; A controller is used to execute the above-described child anti-pinch control method for a car seat.

[0016] A third aspect of the present invention provides an electronic device comprising: At least one processor; and A memory communicatively connected to the at least one processor; wherein, The memory stores instructions that can be executed by the at least one processor, which, when executed by the at least one processor, enables the at least one processor to perform the aforementioned child anti-pinch control method for a car seat.

[0018] A fifth aspect of the present invention provides a computer program product comprising a computer program that, when executed by a processor, implements the above-described child anti-pinch control method for a car seat.

[0019] The beneficial effects of the child anti-pinch control method for car seats in this invention are analyzed as follows: By acquiring detection signals from the seat cushion and backrest areas of the car seat, a highly sensitive, proactive sensing mechanism with zero clamping force is achieved. Based on the independent detection signals from the seat cushion and backrest, combined with specific dynamic adjustment commands, the anti-pinch strategy can be precisely executed for different risk conditions in different seating areas and different operational intentions. This invention not only eliminates the risk of pinching, especially to children, caused by advanced electronically controlled seats during large-travel adjustments at the source, but also takes into account the convenience of normal user operation through differentiated control strategies, significantly reducing the system's false locking rate and constructing a highly reliable and robust seat safety protection mechanism.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. This description is merely illustrative and explanatory, and should not be construed as limiting the scope of protection of the present invention in any way. Specifically, the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0023] It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover 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 process, method, product, or apparatus.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Please see Figure 1 This embodiment provides a child anti-pinch control method for car seats. This method can be applied to the cockpit control system of modern intelligent vehicles, especially for car seats with complex movement functions such as multi-directional electric adjustment, one-button reclining, and zero-gravity mode, to proactively prevent or immediately intervene when pinching occurs, thereby protecting the safety of vehicle occupants, especially children.

[0027] Specifically, the method includes the following steps: Step 110: Obtain the detection signals of the seat cushion area and backrest area of ​​the car seat respectively.

[0028] It should be noted that, in order to eliminate detection blind spots to the greatest extent and achieve all-round anti-pinch protection, the seat cushion area and backrest area in this invention are not limited to the central main support surface of the front of the seat, but are three-dimensional extended areas covering the surface of the seat.

[0029] Optionally, the seat cushion area includes not only the main surface of the seat cushion for contact with the buttocks and legs, but also extends to cover the left and right wings of the seat cushion, the front edge of the seat cushion, and the recessed seam area where the seat cushion extends backward to meet the backrest.

[0030] The backrest area not only includes the main surface of the backrest that the human back contacts, but also extends to cover the left and right wings of the backrest, the shoulder support area, and may also include the side surface of the backrest panel, i.e., the rear area facing the rear passengers. In particular, for linked adjustment modes such as one-touch folding or reclining of the seat, the side surface of the backrest panel and the area at the hinge angle where the backrest extends downward to the seat cushion are high-risk pressure zones. These peripheral and rear areas are all clearly included within the scope of the backrest area of ​​this invention.

[0031] In one embodiment of this application, the detection signal is preferably generated by a capacitive sensor disposed on the surface of the car seat. The capacitive sensor utilizes the principle that the capacitance between electrodes can be changed by the human body as a conductor, enabling highly sensitive liveness detection. Compared to traditional pressure sensors, its detection is independent of the passenger's weight, effectively identifying lighter infants and young children; compared to infrared or camera solutions, it is lower in cost and easier to deploy over a large area on irregular seat surfaces, can penetrate common seat upholstery materials, and is unaffected by clothing thickness, surface stains, etc.

[0032] For example, capacitive sensors can be placed under the leather or fabric layer of a car seat, above the foam layer.

[0033] In another embodiment of this application, the detection signal can also be generated by millimeter-wave radar. For example, one or more miniature millimeter-wave radars can be deployed in the cockpit, such as in the ceiling above the seat or the B-pillar. Beamforming technology or signal processing algorithms are used to analyze the total echo data returned by the radar, and the seat cushion area and backrest area corresponding to the seat backrest are divided at the software level.

[0034] Miniature millimeter-wave radars can also be integrated into the seat structure. For example, one radar can be placed on the upper part of the backrest and the rear part of the seat cushion, so that its detection range is focused on the backrest area and the seat cushion area, respectively.

[0035] This radar can penetrate obstacles such as clothing and thin blankets, and accurately distinguish living organisms from ordinary stationary objects by identifying the micro-motion Doppler features caused by human life activities such as breathing and heartbeat, thereby generating highly reliable detection signals.

[0036] In another embodiment of this application, the detection signal can also be generated by a flexible fabric pressure pad. For example, pressure sensors arranged in a matrix can be integrated on the A-side of the seat cushion area and the backrest area of ​​a car seat.

[0037] It should be noted that side A of the backrest area is the main surface that supports the back of the passenger when sitting in the car seat.

[0038] Specifically, by collecting the force data of each node in the matrix array in real time, a two-dimensional or three-dimensional pressure cloud map of the seat surface is rendered, reflecting the current pressure distribution and shape of the seat and backrest surfaces. Precise detection is achieved based on the dynamic changes in different areas of the pressure cloud map.

[0039] For example, when a child is sitting, their body structure will exhibit irregular biological contours and uneven pressure distribution on the pressure cloud map. Simultaneously, due to the inevitable breathing fluctuations and slight posture adjustments of a living being, the pressure values ​​in the pressure-bearing areas will dynamically fluctuate within a specific threshold range. In contrast, stationary objects not only appear as regular geometric shapes on the pressure cloud map, but the pressure values ​​in each area also typically remain static and constant over a long period. By comprehensively determining the seat pressure cloud map and the dynamic thresholds of the areas, reliable and accurate identification of living targets in the seat cushion and backrest areas can be achieved, generating corresponding detection signals.

[0040] Step 120: In response to receiving a motion adjustment command to control the car seat, execute an active anti-pinch strategy or a semi-active anti-pinch strategy based on the detection signal.

[0041] Optionally, in response to receiving a motion adjustment command to control the car seat, the system determines the current scenario and timing based on the detection signal, and then executes an active anti-pinch strategy or a semi-active anti-pinch strategy.

[0042] It should be noted that the active anti-pinch strategy or the semi-active anti-pinch strategy in this invention both use the controller as the execution subject, and the active and semi-active strategies are divided according to the controller's triggering mechanism and intervention timing.

[0043] Among them, the active anti-pinch strategy is a pre-emptive prevention mechanism. After receiving the adjustment command, and before the actual seat drive is executed, the controller actively initiates and must complete the baseline environment detection behavior in order to predict the seat occupancy status in advance based on the detection signal.

[0044] Specifically, active anti-pinch strategies include: Step 121: Before the motion adjustment command is executed, determine whether there is a target object in the seat cushion area and / or backrest area based on the detection signal. If the target object is determined to exist, restrict or prohibit the execution of the motion adjustment command.

[0045] Specifically, signals from capacitive sensors in the seat cushion and backrest areas are analyzed to determine if a target object, such as a child riding or climbing, is present in the seat cushion and / or backrest areas. If a target object is identified, the movement adjustment command is restricted or prohibited, thereby preventing danger from occurring in the first place.

[0046] Semi-active anti-pinch strategy is a real-time intervention mechanism that operates during the execution of motion adjustment commands and the movement of the car seat. During the legitimate movement of the car seat, the controller's anti-pinch action is triggered by the sudden intervention of the target user or an external object. At this time, the controller itself is in a high-frequency monitoring state, primarily relying on sudden changes in the external environment to activate the anti-pinch response.

[0047] Specifically, semi-active anti-pinch strategies include: Step 122: During the process of executing the motion adjustment command to drive the car seat to move, the changes in the detection signal are monitored in real time to control the actuator used to drive the car seat to perform an anti-pinch action, wherein the anti-pinch action is used to adjust the motion condition of the car seat.

[0048] During this process, the controller monitors the changes in the detection signal in real time and at high frequency. Once a target object is detected to have entered the dangerous area in the movement trajectory, it immediately controls the actuator used to drive the car seat to perform an anti-pinch action, thereby adjusting the movement condition of the car seat to avoid or reduce injury.

[0049] As an example, the actuator could be a seat adjustment motor.

[0050] The method described in this implementation can utilize the dielectric properties of the human body to achieve highly sensitive forward active sensing. Based on the independent detection signals of the detected seat cushion area and backrest area, combined with specific motion adjustment commands, anti-pinch control can be implemented in a differentiated manner.

[0051] Please see Figure 2 The diagram illustrates a flowchart of a child anti-pinch control method for a car seat according to another embodiment of the present invention.

[0052] Step 210: Obtain the detection signals of the seat cushion area and backrest area of ​​the car seat respectively.

[0053] Step 220: In response to receiving a motion adjustment command to control the car seat, execute an active anti-pinch strategy or a semi-active anti-pinch strategy based on the detection signal.

[0054] It should be noted that the explanations of steps 210 and 220 can be found in the relevant descriptions in the above embodiments of the present invention, and will not be repeated here.

[0055] Among them, the active anti-pinch strategy includes: Step 221: Before the motion adjustment command is executed, determine whether there is a target object in the seat cushion area and / or backrest area based on the detection signal. If the target object is determined to exist, restrict or prohibit the execution of the motion adjustment command.

[0056] Specifically, restricting or prohibiting the execution of motion control instructions includes: Step 2211: Determine whether the motion adjustment command matches the preset linkage adjustment mode; if the motion adjustment command matches the preset linkage adjustment mode, when a target object is determined to exist in the backrest area, the preset linkage adjustment mode is prohibited from being executed.

[0057] Optionally, the motion adjustment command can be matched with a preset linkage adjustment mode, which typically involves a wide range of automated movements of multiple degrees of freedom of the seat.

[0058] As an example, the preset linkage adjustment modes include at least: One-touch folding mode, one-touch reclining mode, or zero-gravity linkage mode can be triggered via the vehicle's central control screen or mobile application. In these modes, the driver or passenger may not be able to directly observe the entire situation around the seat.

[0059] In this situation, when a target object is identified in the backrest area, such as a child lying on the backrest or climbing from behind, the preset linkage adjustment mode is directly prohibited from being executed because the risk of the backrest folding backward is extremely high.

[0060] Step 2212: Determine whether the motion adjustment command matches the preset linkage adjustment mode; if the motion adjustment command matches the preset linkage adjustment mode, when it is determined that there is a target object in the seat cushion area and no target object in the backrest area, restrict the adjustment of the car seat backrest so that the angle between the car seat backrest and the car seat cushion does not exceed the preset angle.

[0061] When it is determined that there is a target object in the seat cushion area but not in the backrest area, for example, when a child is sitting normally in the seat, the system can perform some adjustments, but will limit the adjustment of the car seat backrest so that the angle between it and the car seat cushion does not exceed a preset safety angle, in order to prevent the backrest from leaning back excessively and pressing on objects or people behind it.

[0062] As an example, the preset angle can be 90 degrees, meaning the car seat back and seat cushion are perpendicular.

[0063] Semi-active anti-pinch strategies include: Step 222: During the process of executing the motion adjustment command to drive the car seat to move, the changes in the detection signal are monitored in real time to control the actuator used to drive the car seat to perform an anti-pinch action, wherein the anti-pinch action is used to adjust the motion condition of the car seat.

[0064] Optionally, during the process of executing motion adjustment commands to drive the car seat to move, changes in detection signals are monitored in real time. Once a target object is detected to have entered the dangerous area in the movement trajectory, the actuator used to drive the car seat is immediately controlled to perform an anti-pinch action, thereby adjusting the movement condition of the car seat to avoid or reduce injury.

[0065] In this embodiment of the invention, in response to a change in the detection signal indicating the presence of a target object in the backrest area or seat cushion area, the actuator is controlled to perform reverse movement or stop movement.

[0066] Specifically, controlling the actuator to perform reverse motion or stop motion includes: Step 2221: In response to the change in the detection signal indicating the presence of a target object in the backrest area, the actuator is controlled to move in the opposite direction.

[0067] In response to a change in the detection signal indicating the sudden presence of a target object in the backrest area—for example, a child's hand or head accidentally getting stuck in the gap between the moving backrest and the B-pillar or rear seat—the controller should immediately control the actuator to move in the opposite direction. This reverse movement can quickly increase the gap space, creating an opportunity for the trapped object to escape and achieving a force-dissipating effect.

[0068] Step 2222: In response to the change in the detection signal indicating the presence of a target object in the seat cushion area, the actuator is controlled to stop moving.

[0069] The change in the detection signal indicates the sudden presence of a target object in the seat cushion area, possibly due to a child suddenly sitting down. In this case, the safest strategy is to immediately control the actuator to stop moving, maintain the status quo, and wait for further instructions or inspection.

[0070] In some embodiments, in order to ensure that the user's direct control intentions are responded to, when the action adjustment command matches the manual adjustment command, for example, when the user continuously presses the physical adjustment button, the execution priority of the manual adjustment command can be set to be higher than the preset linkage adjustment mode.

[0071] In manual adjustment mode, the trigger threshold of the anti-pinch strategy can be appropriately relaxed or the response method can be changed to avoid misjudgment caused by oversensitivity and ensure that normal seat adjustment is not affected.

[0072] In addition, to enhance user experience and security, this invention can also integrate other auxiliary functions.

[0073] As one possible implementation, when the system restricts or prohibits the execution of motion adjustment commands, or when the actuator performs an anti-pinch action, it can simultaneously output voice or audio-visual prompts. For example, a voice reminder such as "The relevant seat is occupied, one-touch folding has been cancelled" can be issued through the car audio system, or a warning message can be displayed on the central control screen accompanied by a buzzer, to inform the user that the anti-pinch system has intervened.

[0074] Based on the above embodiments, in order to construct a complete, multi-layered protection system, this method may also include implementing a passive anti-pinch strategy as the last line of defense in the event that the active and semi-active strategies fail or are not triggered.

[0075] Please see Figure 3 The diagram illustrates a flowchart of a child anti-pinch control method for a car seat according to another embodiment of the present invention.

[0076] Step 310: Obtain the detection signals of the seat cushion area and backrest area of ​​the car seat respectively.

[0077] Step 320: In response to receiving a motion adjustment command to control the car seat, execute an active anti-pinch strategy or a semi-active anti-pinch strategy based on the detection signal.

[0078] It should be noted that the explanations of steps 310 and 320 can be found in the relevant descriptions in the above embodiments of the present invention, and will not be repeated here.

[0079] Step 330: Collect the motor operating parameters of the actuator, including the motor no-Hall ripple voltage, motor Hall signal or bus current signal.

[0080] During the movement, the controller continuously collects the motor operating parameters of the actuator to determine the seat's movement.

[0081] Step 340: If no target object is found in both the seat cushion area and the backrest area, when the motor operating parameters reach the preset load stall condition, the actuator is controlled to stop in an emergency or move in the reverse direction.

[0082] Specifically, this passive strategy takes effect after the active detection fails to detect the target object and allows the seat to move. Since the active detection fails to detect the target object, that is, the car seat is identified as unloaded at this time. The controller is completely detached from the aforementioned active liveness perception logic of the external environment, and instead passively receives and responds to the non-environmental logic signals transmitted back by the physical obstruction of the actuator itself.

[0083] The preset load stall conditions include: the rise of the bus current signal exceeds the preset current change threshold, or the motor speed obtained based on the motor Hall signal or the motor no Hall ripple voltage decreases and falls below the preset speed threshold.

[0084] Understandably, if the rise in the bus current signal exceeds a preset current change threshold within a short period, it indicates a sudden increase in load; if the motor speed drops sharply below a preset speed threshold, it indicates a motor stall. Based on this, the controller determines that the seat movement is obstructed, for example, it may have caught an object, and immediately controls the actuator to stop urgently or reverse its movement.

[0085] This traditional anti-pinch method based on motor parameters is used as a fallback solution in this invention, which can effectively cover the missed detection scenarios of the capacitive sensing system in extreme cases, and significantly improve the overall safety of the system.

[0086] The method in this embodiment realizes the transformation from "prevention after pinching" to "prevention after knowing". By predicting in advance and intervening in the process, it effectively solves the core pain points of traditional solutions, such as inaccurate identification of low-weight children, blind spots in detection, and harm caused by delayed triggering. Combined with passive anti-pinch strategy as a backup, it builds a comprehensive, reliable and intelligent car seat child anti-pinch system.

[0087] In some implementations that require high levels of security verification, an authorization request may be sent to the vehicle’s central control unit before the linkage adjustment mode is executed.

[0088] Please see Figure 4 The diagram illustrates a flowchart of a child anti-pinch control method for a car seat according to another embodiment of the present invention.

[0089] Step 410: Obtain the detection signals of the seat cushion area and backrest area of ​​the car seat respectively.

[0090] It should be noted that the explanation of step 410 can be found in the relevant descriptions in the above embodiments of the present invention, and will not be repeated here.

[0091] Step 420: In response to receiving the motion adjustment command, an authorization request is sent to the vehicle's central control unit so that the central control unit displays a confirmation interface on the vehicle's display screen.

[0092] In a car interior setting, children who are sitting or climbing are highly likely to accidentally touch the physical adjustment switches located on the side of the seat or in the rear. To avoid serious safety hazards caused by uncontrolled misoperation leading to sudden seat folding, a secondary verification mechanism is implemented by sending an authorization request to the vehicle's central control unit.

[0093] In this embodiment of the invention, after receiving the motion adjustment command, an authorization request is sent to the vehicle's central control unit to confirm whether the motion adjustment command can be executed. After receiving the authorization request, the central control unit displays a confirmation interface on the vehicle's display screen, such as "The rear seats are about to be folded down with one touch. Please confirm that there are no people or obstacles around," so as to realize the confirmation of the human-computer interaction command.

[0094] In this situation, after receiving a request, the driver can visually observe the actual situation in the back seat through the rearview mirror or by looking back, and authorize the execution only after confirming that it is absolutely safe. Even if a child accidentally touches a physical switch on the seat, the command will be blocked as long as the large screen does not receive authorization confirmation, which greatly enhances the driver's overall control over the status of the entire vehicle cabin.

[0095] Step 430: After receiving the authorization confirmation signal returned by the central control unit, an active anti-pinch strategy or a semi-active anti-pinch strategy is executed based on the detection signal. The authorization confirmation signal is generated by the central control unit in response to the user's confirmation input on the confirmation interface.

[0096] In this embodiment of the invention, if the user makes a confirmation input on the confirmation interface of the display screen, the central control unit returns an authorization confirmation signal. After the controller receives the authorization confirmation signal, it will start to execute the subsequent active anti-pinch strategy or semi-active anti-pinch strategy.

[0097] It should be noted that the explanation of the implementation of the active anti-pinch strategy or the semi-active anti-pinch strategy can be found in the relevant descriptions in the above embodiments of the present invention, and will not be repeated here.

[0098] This embodiment effectively blocks the risk of accidental touches in physical blind spots by sending an authorization request to the central control unit before executing an action and requiring the user to confirm the input on the large screen interface. This forms a dual anti-pinch safety protection redundancy that combines automatic judgment by software and hardware logic with manual authorization confirmation by human-machine interaction, ensuring the highest level of safety protection under any complex in-vehicle conditions.

[0099] Please see Figure 5 The diagram illustrates a system block diagram of a child anti-pinch control device for a car seat according to an embodiment of the present invention. This device is the physical carrier of the aforementioned method embodiments and can be integrated into the car seat as a separate control unit, or its function can be implemented by the vehicle's domain controller (such as a cockpit domain controller).

[0100] like Figure 5 As shown, the core of this child anti-pinch control device is the controller 501, which is connected to the detection module 502 and the actuator 503.

[0101] Specifically, the detection module 502 is used to acquire detection signals from the seat cushion area and the backrest area of ​​the car seat, respectively.

[0102] In this embodiment, the detection module is a capacitive sensor array positioned in areas easily touched or approached by a person in the seat cushion and backrest areas. These sensors can be flexible FPC capacitive electrodes, which can conform well to the irregular curved surfaces of the seat, achieving comprehensive coverage of the seat cushion, backrest, side wings, and even seat folding seams, with no blind spots. They are inexpensive and can be wired on the same layer as components such as seat heating wires, making them easy to integrate into existing seat production lines.

[0103] The actuator is used to drive the movement of the car seat, and is usually one or more seat adjustment motors that control the seat's forward and backward movement, height, backrest angle, seat cushion extension and retraction.

[0104] The controller 501 receives a real-time capacitance signal from the detection device and executes a child anti-pinch control method for a car seat as described above.

[0105] Specifically, when the controller receives motion adjustment commands from the vehicle system, application, or physical buttons, it executes an active anti-pinch strategy; during seat movement, it executes a semi-active anti-pinch strategy.

[0106] At the same time, the controller also monitors the motor parameters of the actuator as input for the passive anti-pinch strategy, and performs stall protection when the active detection fails.

[0107] The controller can also connect to interactive devices, such as speakers and warning lights. When any anti-pinch measure is triggered, the controller outputs voice or audio-visual prompts via the interactive device.
