[0002] As people's demand for riding comfort increases, zero-gravity seats that can adjust the posture of the zero-gravity seat to achieve a highly relaxed state for all parts of the occupant's body are becoming more and more widely used. However, different users have different physiological characteristics and relaxation states. For vehicles equipped with zero-gravity seats, it is necessary to adjust the seats according to the specific needs of individual users for intelligent development.

[0060] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0061] As people's demand for riding comfort increases, zero-gravity seats that can adjust the posture of zero-gravity seats to achieve a highly relaxed state for all parts of the occupant's body are becoming more and more widely used. Different users have different physiological characteristics and relaxation states, and the seat angle of the zero-gravity posture should also be changed according to the user's physiological characteristics and relaxation state. For example, the length of the leg rest should match the user's height and adjust the length according to the user's height, and the angle of the zero-gravity posture is also different. Therefore, the adjustment of the zero-gravity seat should be the joint adjustment of the headrest, backrest, seat cushion and leg rest of the seat, so as to always keep the seat close to the user's body and improve comfort. At the same time, because the zero-gravity seat involves too many adjustment function directions, its adjustment convenience during use cannot be ignored: people hope that the zero-gravity seat can achieve multi-functional adjustment to ensure the complete achievement of the zero-gravity posture, and hope that in the process of using the zero-gravity seat, the zero-gravity seat can be adjusted intelligently, safely and conveniently to achieve quick entry or exit of the zero-gravity posture without manually adjusting the switches in all directions step by step.

[0062] A method for controlling a zero-gravity seat is proposed in the prior art. By receiving the signal of the physical button module, the voice recognition module, and the screen soft switch module of the zero-gravity seat, internal calculation processing is performed to drive the zero-gravity seat to perform multi-directional position adjustment, thereby achieving rapid entry or exit of the zero-gravity posture. However, the zero-gravity posture angle of the current zero-gravity seat is a fixed value and cannot be automatically adjusted in an individualized manner. In addition, the linkage adjustment of each module is not considered or implemented during the adjustment process to improve comfort. Based on this, the control method of the zero-gravity seat proposed in the embodiment of the present invention can automatically perform linkage adjustment of various parts of the zero-gravity seat according to the specific needs of individual users, so as to ensure the comfort and support of the overall zero-gravity state, and promote the personalization, convenience, and intelligent development of zero-gravity seat control. Refer to the following. Figure 1-Figure 6 A control method of a zero-gravity chair according to an embodiment of the present invention is described.

[0063] like Figure 1 As shown, it is a flow chart of a control method of a zero-gravity chair according to an embodiment of the present invention, wherein the control method of the zero-gravity chair at least includes steps S1-S3, which are specifically as follows.

[0064] First, before executing step S1 and obtaining the user's body information, it is necessary to determine whether the zero-gravity chair is in the zero-gravity mode, or to determine whether the zero-gravity chair is in the non-zero-gravity mode.

[0065] For vehicles equipped with free zero-gravity seats, when the zero-gravity seat function is turned on, the zero-gravity seat's unfolded posture is identified. For example, the mode of the zero-gravity seat is confirmed by collecting relevant signals. The signal collection mainly collects zero-gravity seat function switch signals, seat position signals, height signals, angle signals, pressure signals, etc. Based on these collected signals, it can be confirmed whether the zero-gravity seat is in zero-gravity mode, and the current state of the zero-gravity seat, i.e., the zero-gravity seat posture, can be confirmed. It should be noted that the zero-gravity seat posture recognition in this embodiment refers to the recognition of the support strength and angle of the headrest, backrest, seat cushion and leg rest of the zero-gravity seat.

[0066] Furthermore, the zero-gravity chair of the embodiment of the present invention should be equipped with a manual adjustment function in addition to having an intelligent adjustment function. Specifically, the zero-gravity chair posture adjustment parameters can be obtained according to user setting instructions, and the user setting instructions include at least one of physical button instructions, touch screen instructions, voice instructions, and gesture instructions. Then, according to the zero-gravity chair posture adjustment parameters, the various action actuators of the zero-gravity chair are controlled to operate in linkage.

[0067] Specifically, the control method of the zero-gravity seat in the embodiment of the present invention can realize manual control. The vehicle or the zero-gravity seat can be set to provide interfaces such as physical buttons or touch screens, or the user can also use voice or control to manually control various parts of the zero-gravity seat to achieve linkage adjustment of various parts of the zero-gravity seat.

[0068] S1, obtaining the user's body information.

[0069] The user's body information, such as human physiological characteristics and human relaxation state information, can be obtained by setting relevant sensors in the seat or using cameras in the vehicle. The human relaxation state information is obtained based on the pressure sensing information of the zero-gravity seat, and the human physiological characteristics information is obtained based on the sensing information of the zero-gravity seat.

[0070] For example, human physiological characteristic information includes human size information, height information, weight information, etc. Human relaxation state information may include user posture information, relative displacement information, etc. Specifically, relevant sensors can be used to obtain human body information of different body shapes and postures. For example, the user's height information can be roughly calculated based on the position and height of the zero-gravity chair. The user's posture includes the contact between the backrest and the waist, the contact between the seat cushion and the thigh, and the contact between the leg rest and the calf. For example, the user's posture can be determined based on the seat sensor information, such as the pressure state, stretching state, etc. It should be noted that the method for collecting data related to human body information is not specifically limited here.

[0071] S2, obtaining zero-gravity chair posture adjustment parameters according to human body information.

[0072] In some embodiments of the present invention, the zero-gravity chair posture adjustment parameters are obtained through a deep learning model based on human physiological characteristic information. The deep learning model is a model that uses human physiological characteristic information as input feature values ​​and zero-gravity chair posture adjustment parameters as output feature values.

[0073] Among them, an initial model can be established first, and a data set of human physiological characteristics information and zero-gravity chair posture adjustment parameters can be obtained. The initial model can be continuously trained with the human physiological characteristics information as input feature values ​​and the zero-gravity chair posture adjustment parameters as output feature values ​​to obtain a deep learning model.

[0074] The zero-gravity chair posture adjustment parameters include the length information of each adjustment component of the zero-gravity chair. The length information of each adjustment component of the zero-gravity chair may include the seat cushion length information and the leg support length information of the zero-gravity chair. The length information is determined according to the human body model, and the human body model is established by matching the human body physiological characteristic information with the standard human body joint information to obtain the user's joint data.

[0075] Specifically, based on the position and height of the zero-gravity chair, the user's height information can be roughly calculated, and the user data can be matched with the human joint data to obtain the data of each joint of the user, thereby establishing a human body model. Based on the human body model, the length of the seat cushion and leg support of the zero-gravity chair can be calculated.

[0076] In some embodiments, the zero-gravity chair posture adjustment parameters also include angle information of various adjustment components of the zero-gravity chair, wherein the angle information is determined based on the human body relaxation state information.

[0077] Specifically, the collected human body information is transmitted to the control system, and the data is analyzed to determine the user's relaxation state based on the human body's relaxation state, and establish a relaxation state benchmark to provide data support for the control algorithm of subsequent linkage adjustment. Specifically, the optimal seat posture can be calculated based on the human body's relaxation state information, including the seat back tilt angle, the length and tilt angle of the seat cushion and leg support, and the encirclement and support strength of the lumbar support.

[0078] S3, controlling the action actuators of the zero-gravity seat to perform linkage adjustment according to the zero-gravity seat posture adjustment parameters to run to the zero-gravity posture of the corresponding user.

[0079] Specifically, various action actuators of the zero-gravity seat are controlled to be linked according to the zero-gravity seat posture adjustment parameters, such as the linked adjustment of the zero-gravity seat backrest tilt angle, seat cushion length and angle, lumbar surround and support strength, leg rest length and angle, and headrest position.

[0080] It is understandable that, in some embodiments, the linkage adjustment includes adjusting the various action actuators of the zero-gravity seat at the same time, that is, controlling the various action actuators of the zero-gravity seat to act at the same time; or, adjusting the various action actuators of the zero-gravity seat in a time-sharing manner within a preset time. Specifically, the preset time can be set according to the adjustment needs, for example, the preset time can be set to 10s, 15s, 20s, 30s, 60s, etc., which is not specifically limited here. Taking setting the preset time to 15s as an example, during the linkage adjustment, the seat back tilt angle, the length of the seat cushion and leg rest, the tilt angle, and the surrounding and support strength of the lumbar support can be adjusted in a time-sharing manner within 15s.

[0081] The operation of the zero-gravity seat is controlled according to the calculated zero-gravity seat posture adjustment parameters, such as automatically adjusting the tilt angle of the backrest, the height and tilt angle of the seat cushion, and the length and tilt angle of the leg rest in linkage. During the adjustment process, the adjustment curve, adjustment ratio and adjustment speed of the linkage adjustment can be further designed to achieve relative stillness between the zero-gravity seat and the user's body, thereby improving the comfort and safety of the zero-gravity seat during operation.

[0082] According to the control method of the zero-gravity seat proposed in the embodiment of the present invention, for a vehicle equipped with a zero-gravity seat, after the zero-gravity seat function is turned on, the zero-gravity posture of the seat can be calculated according to the user's body information, thereby realizing automatic linkage adjustment of the zero-gravity seat according to the user's specific needs, always keeping the seat in close contact with the user's body, improving comfort, and thus ensuring the comfort and support of the overall zero-gravity state. In addition, during the use of the zero-gravity seat, the user does not need to manually adjust the switches in each direction step by step, thereby realizing intelligent, safe, and convenient adjustment of the zero-gravity seat, which promotes the personalized and intelligent development of zero-gravity seat control.

[0083] In some embodiments of the present invention, Figure 2 As shown, it is a flow chart of a control method of a zero-gravity chair according to another embodiment of the present invention, wherein the action actuators of the zero-gravity chair are controlled to be linked and adjusted according to the zero-gravity chair posture adjustment parameters to run to the zero-gravity posture of the corresponding user, that is, the above step S3 may include step S31 and step S32, as follows.

[0084] S31, driving each action actuator of the zero-gravity chair to perform a linkage action according to a target linkage driving model, wherein the target linkage driving model is determined according to the user's body information.

[0085] Among them, the linkage control of the action actuators of the zero-gravity seat in the embodiment of the present invention refers to the linkage adjustment of the zero-gravity seat back tilt angle, seat cushion length and angle, lumbar surround and support strength, leg rest length and angle, and headrest position.

[0086] In some embodiments, the target linkage driving model includes a linkage adjustment curve model, which is a correspondence between human body information and driving signals of various components of the zero-gravity chair.

[0087] Specifically, human body information of different body shapes and postures can be obtained first, including human body size information, weight information, posture information, and relative displacement information of the human body, and then the obtained human body information is preprocessed to standardize the human body information and the relative displacement information of the human body. Feature extraction is performed on or for this information, and a mapping relationship between human body information and zero-gravity chair posture adjustment parameters is established through a deep learning model, that is, a corresponding relationship between human body information and the driving signals of various components of the zero-gravity chair, and a loss function is designed. Among them, the loss function should consider the dynamic relationship between the human body model and the chair parameters, so that the loss function of the linkage adjustment curve model is established based on the relative displacement of the human body and the zero-gravity chair.

[0088] Specifically, the optimization goal can be to minimize the relative displacement information between the human body and the zero-gravity chair, and then the model can be trained using the collected data to ensure that the model can accurately adjust the chair parameters according to the human body characteristics and posture to minimize the relative displacement. The model is verified for data outside the training set to verify the generalization ability of the model on data that has not appeared before. The model is tuned based on the verification results, and the trained model is used to calculate the linkage adjustment curve.

[0089] In some embodiments, the linkage adjustment curve model also includes a user gesture recognition algorithm.

[0090] Among them, the posture recognition algorithm recognizes the user's posture through sensor data, including the contact between the backrest and the waist, the contact between the seat cushion and the thigh, and the contact between the leg rest and the calf; the dynamic adjustment algorithm is based on sensor data and the posture recognition algorithm.

[0091] In some embodiments, driving the motion actuators of the zero-gravity seat to perform motion in linkage according to the target linkage driving model includes: driving the motion actuators of the zero-gravity seat to perform motions respectively and simultaneously according to the linkage adjustment curve model.

[0092] Specifically, since the embodiment of the present invention performs linkage control on the action actuators of the zero-gravity seat, which refers to the linkage adjustment of the zero-gravity seat backrest inclination angle, seat cushion length and angle, lumbar surround and support strength, leg rest length and angle, and headrest position, the user can always keep various parts of the body in fit with the zero-gravity seat during the entire adjustment process, thereby obtaining maximum comfort and body support.

[0093] And, in some other embodiments, the action actuators of the zero-gravity chair are driven to perform linkage according to the target linkage driving model, and also include: when driving the various action actuators of the zero-gravity chair to move, the pressure area between the user's body and the zero-gravity chair is identified according to the user posture recognition algorithm and the pressure area is kept unchanged.

[0094] During the adjustment process, the pressure areas of the backrest and seat cushion are identified, and a dynamic control algorithm is used to adjust the headrest, backrest, seat cushion, leg rest and other parts of the seat in real time, while keeping the pressure areas of the backrest and seat cushion unchanged to prevent relative sliding of the user's body and the seat during the adjustment process, and achieve a smooth transition of pressure changes.

[0095] In some other embodiments, the target linkage driving model includes a linkage adjustment ratio. Driving the motion actuators of the zero-gravity seat to perform linkage according to the target linkage driving model includes: controlling each motion actuator of the zero-gravity seat to perform motion according to the linkage adjustment ratio.

[0096] Specifically, the linkage adjustment ratio is to dynamically adjust the angles of different parts according to the sensor data. For example, when the user leans back, the inclination angles of the backrest and the leg rest will be adjusted in linkage with the angle of the seat cushion at the same time. According to the user's comfort and the requirements of the zero-gravity state, smooth linkage adjustment is performed according to the adjustment curve calculated by the control algorithm.

[0097] In some embodiments, the target linkage driving model includes a linkage adjustment speed. Specifically, the linkage adjustment speed includes a first speed value and a second speed value executed successively, the first speed value is greater than the second speed value, wherein the first speed value and the second speed value can be set as needed, and no specific limitation is made here.

[0098] The method of driving the action actuators of the zero-gravity seat to perform linkage according to the target linkage driving model includes: adjusting the actions of the action actuators of the zero-gravity seat according to the linkage adjustment speed. The linkage adjustment speed is determined according to the speed gear selection instruction.

[0099] Specifically, when performing linkage adjustment, the linkage adjustment speed of the zero-gravity chair needs to be set. Based on the user's experience and safety, the linkage adjustment speed can be designed to be adjustable and divided into different gears for manual selection by the user. For example, it can be set that in the initial stage of adjustment, the linkage adjustment speed is set to a faster speed, that is, the first speed value, to quickly respond to the user's posture changes; when the inclination angle of the backrest, seat cushion and leg rest gradually approaches the target angle, the system will gradually slow down the adjustment speed, that is, reduce the speed to the second speed value, to ensure smooth adjustment and avoid discomfort.

[0100] In addition, during the linkage adjustment process of the zero-gravity seat, the zero-gravity seat can also inform the user of the current adjustment status and speed through the display, slight vibration or sound prompts to ensure that the user understands the response of the seat.

[0101] The present invention calculates the linkage adjustment curve model, linkage adjustment ratio and linkage adjustment speed of the seat according to human body information and driving signals of various components of the zero-gravity seat, thereby realizing linkage adjustment of parts such as the headrest, backrest, seat cushion and leg rest.

[0102] S32, when the movement amount of each movement actuator of the zero-gravity seat satisfies the zero-gravity seat posture adjustment parameter, the zero-gravity seat is in the user's zero-gravity posture.

[0103] The control method of the zero-gravity chair proposed in the embodiment of the present invention adopts a linkage adjustment method. During the adjustment process, the user's body parts are closely fitted with the zero-gravity chair parts, and the body joints are supported, which greatly improves the user's comfort during the adjustment process. It has higher applicability and realizes automatic personalized setting of zero-gravity chair adjustment.
