[0012] Compared with the prior art, this application has the following beneficial effects: In summary, the workflow during the initial use of this device relies on pressure sensors (seat cushion / backrest / headrest) to obtain human body posture data and seating position distribution, and takes the following actions: if there is data on the seat cushion / backrest but no data in the headrest area, it indicates that the head is not in contact with the headrest. In this case, the headrest is controlled to move forward until the data from the pressure sensor in the headrest area meets the human body's comfortable pressure. Then, based on the pressure distribution of the first pressure sensor of the headrest at this time, the main force position of the human brain at the headrest can be analyzed. By adjusting the vertical position of the headrest, the human brain / neck is in a suitable support position.

[0013] Furthermore, the driving process relies on pressure sensors (seat cushion / backrest / headrest) to obtain human body posture data and seating distribution. To avoid safety hazards introduced by manual adjustment, the controller will adaptively adjust the headrest in the following situations: ① After a certain driving time, the controller will switch different pressure curves according to the duration (1 hour, 2 hours) to readjust the headrest position and provide a comfortable position for the current situation; ② When the positions of other motors change, such as the backrest motor / lifting motor, the headrest's force position is affected by the change in tilt angle, and the controller will readjust according to the new pressure position; ③ The occupant can actively leave the headrest or apply pressure to the headrest, guiding a sudden change in pressure value, triggering the headrest's adaptive adjustment, which automatically follows the occupant's head to provide support. Attached Figure Description To more clearly illustrate the technical solutions in the specific embodiments of this application or the prior art, the drawings used in the description of the specific embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of this application. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

[0016] The following detailed embodiments are provided to help readers gain a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the sequence of operations described herein is merely illustrative and is not limited to the sequence set forth herein. Changes that will be apparent after understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted. This application provides a control method for an adaptively adjustable electrically folding headrest. This method uses pressure sensing technology to monitor the pressure distribution of the occupant in different areas of the seat in real time, and combines this with a preset calibrated pressure curve to achieve automatic and precise adjustment of the posture of the electrically folding headrest. This method aims to solve the problems of existing headrests requiring manual adjustment and being unable to adapt to different body types and long-term driving posture changes, thereby improving riding comfort and safety. The implementation steps of this method are described in detail below with reference to the accompanying drawings.

[0017] like Figure 3 As shown, the car seat is first divided into three functional areas: the seat cushion area (seat cushion 7), the backrest area (backrest 6), and the headrest area (headrest 5). This division method facilitates the perception of the occupant's body posture and sitting position.

[0018] A first pressure sensor 1 (i.e., the first sensor) is installed in the headrest area to directly monitor the contact pressure and its distribution between the occupant's head and the headrest. Considering that the comfort of head support mainly depends on the magnitude of the pressure and the height of the point of application, this application further optimizes the configuration of the first pressure sensor. Specifically, the number of first pressure sensors is set to M1, and these sensors are arranged at intervals along the vertical direction of the headrest. For example, multiple sensor points can be set from top to bottom, respectively labeled as first pressure sensor number one, first pressure sensor number two, ... up to first pressure sensor number M1. This vertical array arrangement can effectively capture the pressure information of the head at different height positions on the headrest, providing a data basis for subsequent vertical adjustment of the headrest.

[0019] Relying solely on sensors in the headrest area may not be sufficient to effectively trigger adjustments or determine the presence of a occupant when they are not seated or are initially seated. To further improve the system's response accuracy and reliability, this application, in an optional embodiment, also adds pressure sensor arrays to the seat cushion and backrest areas.

[0020] Specifically, M2 second pressure sensors 2 are installed in the seat area, arranged in a special "lightning bolt" shape. This non-uniform, asymmetrical arrangement better adapts to the physiological curves of the human buttocks and thighs, more accurately obtains the pressure distribution of the ischial tuberosities and thighs, and thus more accurately determines whether the occupant is seated and their sitting posture.

[0021] M3 third pressure sensors 3 are installed in the backrest area. To further enhance the sensing capability of torso posture, especially lateral support and backrest fit, this application arranges some of the third pressure sensors vertically at intervals on the side wings of the seat back to monitor the lateral pressure on the occupant's torso. The other sensors are arranged in a matrix array in the central area of ​​the backrest to comprehensively monitor the positive pressure distribution on the back. Through the coordinated sensing of the seat cushion and backrest areas, the system can confirm the presence of the sensor as soon as the occupant sits down and provide auxiliary reference for subsequent headrest adjustment decisions.

[0022] Based on the above structure, combined with Figures 1-3 As shown, the control method for the adaptively adjustable electrically folding headrest provided in this application specifically includes the following steps: Area division step 100: Divide the car seat into the corresponding seat cushion, backrest and headrest areas.
