[0060] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely intended to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art may make adjustments to these embodiments as needed to adapt to specific applications without departing from the principles of the present invention and within the scope of protection of the present invention.

[0061] The present invention provides a vehicle comprising a seat system, such as Figure 1 As shown, the seat system includes a seat body 5, a seat cushion 1 provided on the seat body 5, a telescopic body 2, a drive device 3, and a controller 3. The controller 3 is in communication with the drive device 3. The telescopic body 2 is used to change the compression of the seat cushion 1 by telescoping, and the drive device 3 is used to drive the telescopic cavity to telescope. The telescopic body 2 can be an air bag, and the drive device 3 can be an air pump. The air outlet of the air pump can be connected to the air inlet of the air bag directly or indirectly through an air pipe. Possibly, the seat cushion 1 has a foam structure, and the air bag is provided between the foam structure and the seat body 5, so that when the air bag expands, the compression of the foam structure of the seat cushion 1 is greater, and when the air bag contracts, the compression of the foam structure of the seat cushion 1 is less, thereby changing the softness and hardness of the seat cushion 1.

[0062] The present invention does not limit the specific form of the foam structure, such as polyurethane foam, memory foam, or latex foam. Of course, as long as the seat cushion 1 can be compressed, the foam structure can be replaced with other forms, such as rubber pads, non-foamed sponge materials, etc. These reasonable replacements do not deviate from the principles of the present invention and are within the scope of protection of the present invention. The seat cushion 1 of the present invention is preferably a seat cushion, but can also be a back cushion, etc. The present invention does not impose specific limitations on it.

[0063] Furthermore, the specific configurations of the telescopic body 2 and drive device 3 described above are not fixed. As long as the telescopic body 2 can change the compression of the seat cushion 1 by extending and retracting, and the drive device 3 can drive the telescopic body 2 to extend and retract, adjustments to their specific configurations do not deviate from the principles of the present invention and are within the scope of protection of the present invention. For example, the telescopic body 2 and drive device 3 can be configured as electric push rods, each mounted at each end of the seat body 5, with a flat plate structure mounted at the end of the telescopic rod of each push rod. The flat plate structure is positioned between the foam structure and the seat body 5, so that the flat plate structure can be driven to extend and retract by the push rod to change the compression of the seat cushion 1. Such adjustments do not deviate from the principles of the present invention and are within the scope of protection of the present invention.

[0064] like Figure 2As shown, the present invention also provides a method for controlling a vehicle seat system, comprising the following steps:

[0065] Step S100: Obtain a first parameter value.

[0066] Step S200: Based on the first parameter value, controlling the driving device to operate so that the compression amount of the seat cushion is the compression amount corresponding to the first parameter value.

[0067] Step S300: After a first preset time has passed, based on a preset second parameter value, the driving device is controlled to operate so that the compression amount of the seat cushion is the compression amount corresponding to the preset second parameter value.

[0068] Among them, the first parameter value and the preset second parameter value can characterize the compression amount of the seat cushion. The first parameter value is different from the preset second parameter value. It can be understood that the difference here refers to the difference in numerical value between the first parameter value and the preset second parameter value. The first parameter value and the preset second parameter value can be the air bag pressure value, the air bag inflation amount or the seat cushion compression amount, etc., as long as the size of the parameter value can reflect the size of the seat cushion compression amount. The preset second parameter value can be an adjustable value, and the user can directly enter the preset second parameter value that suits his or her preferences on the vehicle screen. The preset second parameter value can also be a default preset second parameter value set by the system, which can be a preset second parameter value that meets the needs of most users through big data statistics, etc., as a balance parameter value.

[0069] As a possible implementation, after step S300, if the second preset time has passed, the process returns to step S200.

[0070] To illustrate with a specific implementation method: a first air pressure value is obtained, and based on the first air pressure value, the air pump is controlled to inflate or deflate, so that the air pressure value of the air bag is adjusted to the first air pressure value. At this time, the compression of the seat cushion will change. After a first preset time, the air pump is controlled to inflate or deflate based on a preset second air pressure value, so that the air pressure value of the air bag is adjusted to the preset second air pressure value. Taking specific numerical values ​​as an example, if the seat cushion thickness is 10cm, if the air bag is in the default uninflated state, the corresponding seat cushion compression is 0cm; the first air pressure value is 30% of the total air pressure value, and the corresponding seat cushion compression is 3.5cm; the preset second air pressure value is 50% of the total air pressure value, and the corresponding seat cushion compression is 5cm. The first preset time and the second preset time are both 30 minutes. First, the air bag is inflated by an air pump to a pressure of 30% of the total pressure (a pressure sensor may be provided on the air bag to detect whether the total pressure reaches 30%, as will be the case below). After 30 minutes, the air bag is inflated by an air pump to a pressure of 50% of the total pressure. After another 30 minutes, the air bag is deflated by an air pump to a pressure of 30% of the total pressure, and this cycle is repeated. The total pressure may be factory-set. When designing the air bag, the manufacturer may calculate or measure the total pressure based on the size, shape, material, and intended function of the bag.

[0071] It should be noted that the values ​​of the above parameters are not unique, and the present invention does not limit their specific values. The value range of the first preset time and the second preset time is preferably 20 minutes to 40 minutes. For example, it is 30 minutes, 35 minutes, etc. The values ​​of the first preset time and the second preset time can be the same or different. The value range of the preset second air pressure value can be 40%-60% of the total air pressure value. For example, it can be 50%, 45%, or 55%, etc., to provide a better balance between support and comfort.

[0072] The human body's fatigue level and the requirements for seat comfort change dynamically during driving. In different driving stages, such as when just getting on the car, after driving for a period of time, or in the second half of a long-distance drive, the human body's requirements for the softness and hardness of the seat may be different. The present invention first adjusts the air bag pressure value to a first pressure value so that the softness and hardness of the seat can better fit the user's own needs and preferences. After a first preset time, in order to avoid the seat maintaining a supporting posture for a long time, which may easily cause physical discomfort to the user, the air bag pressure value is adjusted to a preset second pressure value. After the second preset time, the air bag pressure value is adjusted back to the first pressure value, and this cycle repeats. In this way, the compression of the seat cushion can be adjusted according to the preset time, dynamically adapting to these changes and providing users with a more comfortable riding experience.

[0073] As a possible implementation, before step S100, the control method of the present invention further includes step S400: identifying user identity information when a seat occupancy signal is obtained.

[0074] Step S100 further includes: acquiring a first parameter value corresponding to the user identity information.

[0075] Different users have different body shapes, sitting habits, and personal preferences for seat firmness. By identifying the user and determining the corresponding first air pressure value, the seat cushion firmness can be precisely adjusted to each user's preferences. For example, if one user prefers a slightly softer seat, the corresponding first air pressure value will be relatively low, resulting in less air bag inflation and less seat cushion compression. Meanwhile, if another user prefers a slightly firmer seat, the corresponding first air pressure value will be higher, resulting in more air bag inflation and greater seat cushion compression. Therefore, upon boarding the vehicle, the air bag pressure is adjusted according to the first air pressure value corresponding to the user's identity, allowing the seat to tailor to the user's needs and provide a relatively comfortable ride.

[0076] In step S400, the seat occupancy signal may be an SBR (Seat Belt Reminder) occupancy signal - a seat belt occupancy signal. When the seat occupancy signal is obtained and reaches a third preset duration, the user identity information is identified. Of course, the seat occupancy signal may also be a pressure signal or a weight signal, etc. For example, a pressure sensor is provided on the seat. When the pressure sensor detects a pressure signal, and the detected pressure value is greater than or equal to the preset pressure value, the user identity information is identified. Furthermore, a plurality of pressure sensors may be installed on the car seat, and these sensors are distributed on the seat cushion in the form of a matrix. When the user takes the seat, each sensor will obtain the pressure value of the position in real time, thereby obtaining the pressure distribution data of the entire seat surface. If the pressure distribution data conforms to the preset distribution rules, the user identity information is identified. The preset distribution rules can establish pressure distribution models corresponding to different body shapes based on a large amount of human body data, and match the pressure distribution data detected in real time by the pressure sensor with the preset distribution rules. Pattern recognition algorithms such as neural network algorithms and cluster analysis algorithms can be used. Taking a neural network algorithm as an example, pressure distribution data is used as input. After the neural network model is trained, it will output a result that matches the preset rules. If the output matches the user's pressure distribution rules, the user's identity can be preliminarily identified.

[0077] The present invention does not limit the specific implementation methods for identifying user identity information. For example, a vehicle's camera can capture the interior of the vehicle. Image recognition technology can be used to extract and analyze the captured facial features, which are then compared and matched with stored user image feature data to identify the user. For example, facial features such as the vehicle owner and frequent passengers can be pre-entered into the vehicle system. After the camera captures the current passenger's face, the system analyzes key features such as facial proportions and contour characteristics, and compares them with the stored information. If the similarity reaches a certain threshold, the user's identity can be determined. Alternatively, a pupil recognition device (possibly integrated into certain vehicle components, such as a specific monitoring area within the vehicle) can be used to collect pupil features of the user, such as pupil size, texture, color depth, and unique physiological characteristics. This collected pupil feature information is then compared with the user's pupil feature data pre-stored in the vehicle system. If the match meets the corresponding criteria, the user's identity can be accurately identified. Alternatively, a neural network algorithm within a pattern recognition algorithm can be used, taking pressure distribution data as input. A trained neural network model will output a result that matches a preset rule. If the output matches a user's pressure distribution rule, the user's identity can be initially identified. Of course, the above description is merely illustrative; as long as the user's identity information can be identified, the specific identification method can be any existing or future possible implementation method.

[0078] It should be noted that the present invention, when receiving a seat occupancy signal, identifies the user's identity information to prevent unintended airbag activation. However, the present invention can also omit the determination of whether a seat occupancy signal has been received and directly identify the user's identity information. These adjustments do not deviate from the principles of the present invention and are within its scope of protection.

[0079] As a possible implementation, the present invention can only recognize user identity information and execute steps S100 to S300 when the preset automatic adjustment function is enabled. This can better adapt to user usage habits and avoid using the automatic adjustment function when the user does not need it. A start switch can be connected to the seat system controller. Selecting the "On" option on the screen indicates that the automatic adjustment function is enabled. Alternatively, a separate button can be provided, and when pressed, the automatic adjustment function is enabled.

[0080] As a possible implementation method, the control method of the present invention further includes:

[0081] Step S400: Determine whether the user-set parameter value is obtained.

[0082] Step S500: If the user-set parameter value is not obtained, then step S400 and steps S100 to S300 are executed.

[0083] Step S600: If the set parameter value is obtained, the driving device is controlled to operate based on the set parameter value so that the compression amount of the seat cushion is the compression amount corresponding to the set parameter value.

[0084] Step S700: After a first preset time has passed, based on a preset second parameter value, the driving device is controlled to operate so that the compression amount of the seat cushion is the compression amount corresponding to the preset second parameter value.

[0085] Step S800: After the second preset time has passed, the process returns to step S600.

[0086] When the user has set the parameter value, it means that the user has his or her own clear preferences and control intentions for the state of the seat. At this time, step S400 and steps S100-S300 are not executed, avoiding the interference of the system's automatic adjustment with the user's manual settings. When the set parameter value is obtained, the air bag pressure value will be adjusted to the set parameter value, so that the softness and hardness of the seat can further fit the user's own needs and preferences. After the first preset time, in order to avoid the seat maintaining a supporting posture for a long time, which is easy to cause physical discomfort to the user, the air bag pressure value is adjusted to the preset second pressure value. After the second preset time, the air bag pressure value is adjusted back to the set pressure value, and this cycle repeats. In this way, the compression of the seat cushion can be adjusted according to the preset time, dynamically adapting to these changes and providing users with a more comfortable riding experience.

[0087] Regarding setting parameter values, three options can be set on the screen: soft, medium, and firm. Each of these options corresponds to an airbag pressure value. When the user selects any of these options, the system will obtain the airbag pressure value for the corresponding option. For example, soft corresponds to 20% of the total air pressure value, medium corresponds to 50% of the total air pressure value, and firm corresponds to 80% of the total air pressure value. When the user selects soft, the system will obtain 20% of the total air pressure value, and when the user selects firm, the system will obtain 80% of the total air pressure value. For short trips, the user can choose a soft mode, and for long trips, a firm mode, thereby providing the user with greater comfort. Of course, the above description is only exemplary, and the acquisition method can be adjusted, for example, the user can enter the set parameter value himself, etc. Such adjustments do not deviate from the principles of the present invention and are within the scope of protection of the present invention.

[0088] As a possible implementation, step S700 is performed only when the preset automatic adjustment function is enabled, thereby avoiding the hardness adjustment without the user's knowledge and improving driving safety.

[0089] As a possible embodiment, step S200, which is executed for the first time, further includes: controlling the drive device based on the first parameter value to adjust the compression of the seat cushion at a first preset speed to a compression amount corresponding to the first parameter value. Step S300 further includes: after a first preset time has elapsed, controlling the drive device based on a preset second parameter value to adjust the compression of the seat cushion at a second preset speed to a compression amount corresponding to the preset second parameter value; wherein the first preset speed is greater than the second preset speed.

[0090] When a user first gets into the vehicle, the seat cushion compression is adjusted at a faster first preset speed, quickly achieving the user's desired seat firmness. This allows the user to quickly reach a comfortable state without having to wait for the seat cushion to adjust. After the first preset time, the seat cushion compression is adjusted at a slower second preset speed to avoid sudden changes in seat cushion compression after the user has adjusted to the initial seat position, which could cause discomfort. The slower second preset speed allows the user's body to experience a smoother transition, avoiding discomfort caused by sudden changes in seat position and allowing the body to naturally adapt to the transition from the initial position that suits the user's identity to a balanced state.

[0091] Furthermore, after the second preset time has elapsed, the process returns to step S200, and the compression of the seat cushion is adjusted to the compression corresponding to the first parameter value according to the second preset speed. The present invention does not limit the specific values ​​of the first and second preset speeds. For example, the first preset speed is 0.5 cm / s to 2 cm / s, such as 1 cm / s, 1.5 cm / s, and so on. The second preset speed is 0.05 cm / s to 0.2 cm / s, such as 0.08 cm / s, 0.1 cm / s, and so on.

[0092] As a possible implementation, the first preset time is greater than the second preset time. During the initial stage of driving, the seat cushion's hardness matches the user's identity information, allowing the seat to reach an initial, comfortable fit. Therefore, after a relatively long first preset time, the seat cushion switches to a compression value corresponding to a preset second parameter value, relieving fatigue by changing the seat's hardness. After a relatively short second preset time, the seat cushion returns to its initial, user-specific compression value, better meeting the user's desired seat hardness and providing greater comfort.

[0093] The loop of steps S200 to S300 may be exited upon a preset end time. This preset time can be set based on experimentation or user preference. For example, the loop of steps S200 to S300 may be exited after executing for 1.5 to 8 hours. For short trips, the preset time may be 2 hours, for long trips, 7 hours, and so on. Furthermore, the loop may be exited if the preset automatic adjustment function is disabled.

[0099] Step S903: Acquire a first air pressure value corresponding to the user identity information.

[0101] Step S905: After the first preset time, the air pump is controlled to operate so that the air pressure in the air bag reaches a preset second pressure value.

[0102] Step S906: After the second preset time, return to step S904.

[0103] Step S907: Determine whether the loop of step S904 to step S906 has been executed for a preset time. If so, exit the loop; if not, continue the loop.

[0104] Step S908: Control the air pump to make the air pressure in the air bag reach the set pressure value.

[0105] Step S909: After the first preset time, the air pump is controlled to operate so that the air pressure in the air bag reaches a preset second pressure value.

[0106] Step S910: After the second preset time, return to step S908.

[0107] Step S911: Determine whether the loop of step S908 to step S910 has been executed for a preset time. If so, exit the loop; if not, continue the loop.
