[0060] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application. Those skilled in the art can make adjustments as needed to adapt to specific application occasions, which do not deviate from the principles of the present application and are within the protection scope of the present application.

[0061] The present application provides a vehicle, which comprises a seat system, such as Figure 1 As shown, the seat system comprises a seat body 5, a seat cushion 1 arranged on the seat body 5, a telescopic body 2, a driving device 3 and a controller 3, the controller 3 is in communication connection with the driving device 3, the telescopic body 2 is used to change the compression amount of the seat cushion 1 by telescoping, and the driving device 3 is used to drive the telescopic body 2 to telescope. The telescopic body 2 can be a gas bag, and the driving device 3 can be a gas pump, and the gas outlet of the gas pump can be directly or indirectly connected with the gas inlet of the gas bag through a gas pipe. Possibly, the seat cushion 1 has a foamed structure, and the gas bag is arranged between the foamed structure and the seat body 5, so that when the gas bag expands, the compression amount of the foamed structure of the seat cushion 1 is larger, and when the gas bag contracts, the compression amount of the foamed structure of the seat cushion 1 is smaller, so as to change the hardness of the seat cushion 1.

[0062] Among them, the present application does not limit the specific form of the foamed structure, for example, polyurethane foam, memory cotton or latex foam and the like. Of course, as long as the seat cushion 1 can be compressed, the foamed structure can be replaced by other forms, such as rubber pad, non-foamed sponge material and the like, and these reasonable replacements do not deviate from the principles of the present application and are within the protection scope of the present application. The seat cushion 1 of the present application is preferably a seat cushion, and can also be a back cushion and the like. The present application does not make specific limitations.

[0063] In addition, the specific forms of the telescopic body 2 and the driving device 3 introduced above are not fixed, as long as the telescopic body 2 can change the compression amount of the seat cushion 1 by telescoping, and the driving device 3 can drive the telescopic body 2 to telescope, the adjustment of the specific setting form does not deviate from the principles of the present application and is within the protection scope of the present application. For example, the telescopic body 2 and the driving device 3 can be constructed as an electric push rod, the electric push rod is installed at both ends of the seat body 5, and a flat plate structure is installed at the end of the telescopic rod of the electric push rod at both ends, the flat plate structure is arranged between the foamed structure and the seat body 5, so as to drive the flat plate structure to telescope by the electric push rod, so as to change the compression amount of the seat cushion 1, and these adjustments do not deviate from the principles of the present application and are within the protection scope of the present application.

[0064] As shown in the accompanying drawings, Figure 2As shown, the application also provides a control method of a seat system of a vehicle, comprising the following steps:

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

[0066] Step S200: based on the first parameter value, controlling the driving device to act so as to make the compression amount of the seat cushion be a compression amount corresponding to the first parameter value.

[0067] Step S300: after a first preset time elapses, based on a preset second parameter value, controlling the driving device to act so as to make the compression amount of the seat cushion be a compression amount corresponding to the preset second parameter value.

[0068] The first parameter value and the preset second parameter value can represent the compression amount of the seat cushion, and the first parameter value is different from the preset second parameter value. It can be understood that the difference here refers to the numerical size of the first parameter value being different from that of the preset second parameter value. The first parameter value and the preset second parameter value can be air bag air pressure value, air bag inflation amount, or seat cushion compression amount, etc., as long as the size of the parameter value can reflect the size of the compression amount of the seat cushion. The preset second parameter value can be an adjustable value, and the user can directly input the preset second parameter value that fits his own preference on the screen of the vehicle. 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 after big data statistics, etc., to serve as a balance parameter value.

[0069] As a possible implementation, after step S300, if a second preset time elapses, step S200 is executed again.

[0070] With a specific embodiment as an example: a first air pressure value is obtained, the air pump is controlled to inflate or deflate based on the first air pressure value, so that the air pressure value of the air bag is adjusted to the first air pressure value, at this time, the compression amount 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. With specific numerical values as an example: the thickness of the seat cushion is 10 cm, and if the air bag is in a default un-inflated state, the corresponding compression amount of the seat cushion is 0 cm; the first air pressure value is 30% of the total air pressure value, and the corresponding compression amount of the seat cushion is 3.5 cm; the preset second air pressure value is 50% of the total air pressure value, and the corresponding compression amount of the seat cushion is 5 cm, and the first preset time and the second preset time are both 30 minutes. Then, the air pump is first inflated to adjust the air pressure value of the air bag to 30% of the total air pressure value (an air pressure sensor can be provided on the air bag to detect whether 30% of the total air pressure value is reached, and the same applies below), after 30 minutes, the air pump is inflated to adjust the air pressure value of the air bag to 50% of the total air pressure value, and after 30 minutes, the air pump is deflated to adjust the air pressure value of the air bag to 30% of the total air pressure value, and the cycle is repeated. The total air pressure value can be set by the manufacturer when designing the air bag, and the manufacturer can calculate or measure the total air pressure value according to the size, shape, material and expected function of the air bag.

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

[0072] The degree of fatigue of the human body and the requirement for seat comfort during driving are dynamically changing. In different driving stages, such as just getting on the car, after driving for a period of time, or the latter half of long-distance driving, the user's demand for seat hardness may be different. The present application first adjusts the air pressure value of the air bag to the first air pressure value, so that the hardness of the seat can better meet the user's own needs and preferences, and after a first preset time, to avoid the seat maintaining a support posture for a long time, which can easily cause the user's body to be uncomfortable, the air pressure value of the air bag is adjusted to the preset second air pressure value, and after a second preset time, the air pressure value of the air bag is adjusted back to the first air pressure value, and the cycle is repeated. Thus, the compression amount of the seat cushion can be adjusted according to the preset time to dynamically adapt to these changes and provide a more comfortable riding experience for the user.

[0073] As a possible implementation, before step S100, the control method further comprises step S400: in the case that the seat occupancy signal is acquired, the user identity information is identified.

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

[0075] Different users have differences in body shape, sitting habits, personal preferences for seat softness, etc. By identifying the user identity to determine the corresponding first air pressure value, the softness of the seat cushion can be accurately adjusted according to the preferences of each user. For example, some users prefer a slightly softer seat, and the corresponding first air pressure value will be relatively low, so that the air bag has less air and the seat cushion has less compression. Some users prefer a slightly harder seat, and the corresponding first air pressure value will be higher, so that the air bag has more air and the seat cushion has more compression. Thus, when getting on the car, the air pressure of the air bag is adjusted according to the first air pressure value corresponding to the user identity, so that the seat conforms to the user's needs and provides a relatively comfortable ride support for the user.

[0076] In step S400, the seat occupancy signal can be an SBR (Seat Belt Reminder) occupancy signal - a seat belt occupancy signal. For example, when the seat occupancy signal is acquired for a third predetermined time, the user identity information is identified. Of course, the seat occupancy signal can also be a pressure signal or a weight signal, etc. For example, a pressure sensor is provided on the seat, and when the pressure sensor detects a pressure signal and the detected pressure value is greater than or equal to a predetermined pressure value, the user identity information is identified. Further, a plurality of pressure sensors can be installed on the car seat, and these sensors are distributed in a matrix form on the seat cushion. When the user sits down, each sensor will obtain the pressure value at the location in real time, thereby obtaining the pressure distribution data of the entire seat surface. If the pressure distribution data meets the preset distribution rule, the user identity information is identified. The preset distribution rule can be established according to a large amount of human body data to establish a pressure distribution model corresponding to different body shapes. The pressure distribution data detected by the pressure sensor in real time is matched with the preset distribution rule. Pattern recognition algorithms such as neural network algorithms, clustering analysis algorithms, etc. can be used. Taking the neural network algorithm as an example, the pressure distribution data is input into the trained neural network model, and the model outputs a result matched with the preset rule. If the output result matches the user's pressure distribution rule, the user identity can be preliminarily identified.

[0077] Wherein, the present application does not limit the specific implementation of identifying user identity information. For example, the camera equipped on the vehicle can shoot the situation inside the vehicle, extract and analyze the portrait features shot by image recognition technology, and compare and match with the stored user image feature data, so as to identify the user identity. For example, the facial image and other characteristic information of the vehicle owner and the frequently used passengers are recorded in advance in the vehicle system, after the camera shoots the face of the current passenger, the system analyzes the key features of the facial features, such as the proportion of the facial features, the contour characteristics, and compares with the stored information, if the similarity reaches a certain threshold, the user identity can be determined. Or use the pupil recognition device (may be integrated in some parts of the vehicle, such as a specific monitoring area in the vehicle), collect the pupil features of the user, such as the size, texture, color depth and unique physiological characteristics of the pupil. These collected pupil feature information will be compared with the user pupil feature data stored in the vehicle system in advance, when the matching degree meets the corresponding standard, the user identity can be accurately identified. Or use the neural network algorithm in the pattern recognition algorithm, take the pressure distribution data as input, pass through the trained neural network model, the model will output the result matched with the preset rule, if the output result is consistent with the pressure distribution rule of a certain user, the user identity can be preliminarily identified. Of course, the above introduction is only exemplary, as long as the user identity information can be identified, the specific identification method can be any possible implementation method existing now or in the future.

[0078] It should be noted that, in the case of obtaining the seat occupancy signal, the present application can identify the user identity information, and can avoid the airbag from being started at will. However, the present application can also omit the judgment of whether the seat occupancy signal is obtained, and directly identify the user identity information. These adjustments do not deviate from the principles of the present application, and are within the scope of protection of the present application.

[0079] As a possible implementation, the present application can identify the user identity information and execute steps S100 to S300 only when the preset automatic adjustment function is enabled. Thus, the use habit of the user can be better adapted, and the automatic adjustment function can be avoided when the user does not need it. Wherein, the starting switch can be connected with the controller of the seat system. For example, when the opening option is selected on the screen, it means that the automatic adjustment function is enabled. Or a separate button is set, when the button is pressed, it means that the automatic adjustment function is enabled.

[0080] As a possible implementation, the control method of the present application further comprises:

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

[0082] Step S500: if the user set parameter value is not obtained, steps S400, 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 the first preset time elapses, the driving device is controlled to operate based on the preset second parameter value, 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 elapses, the step S600 is returned to be executed.

[0086] When the user has set the parameter value, it indicates that the user has a clear preference and control intention for the state of the seat. At this time, steps S400 and S100-S300 are not executed, avoiding the interference of the system automatic adjustment to the user's manual setting. When the set parameter value is obtained, the air bag pressure value is adjusted to the set parameter value, so that the softness of the seat can further meet the user's own needs and preferences. After the first preset time elapses, the air bag pressure value is adjusted to the preset second air pressure value to avoid the seat remaining in a support posture for a long time, which can easily cause the user's body to be uncomfortable. After the second preset time elapses, the air bag pressure value is adjusted back to the set air pressure value, and the cycle is repeated. Thus, the compression amount of the seat cushion can be adjusted according to the preset time to dynamically adapt to these changes and provide a more comfortable riding experience for the user.

[0087] Regarding the set parameter value, three options of soft, moderate, and hard can be set on the screen, and soft, moderate, and hard each correspond to an air bag pressure value. When the user selects any one of the options, the system can obtain the air bag pressure value corresponding to the selected option. For example, soft corresponds to 20% of the total air pressure value, moderate corresponds to 50% of the total air pressure value, and hard corresponds to 80% of the total air pressure value. When the user selects soft, the system can obtain 20% of the total air pressure value, and when the user selects hard, the system can obtain 80% of the total air pressure value. When the user travels for a short distance, the soft mode can be selected, and when the user travels for a long distance, the hard mode can be selected, so that the user can be more comfortable. Of course, the above introduction is only exemplary, and the obtaining method can be adjusted, for example, the user can input the set parameter value, and these adjustments do not deviate from the principles of the present application and are within the protection scope of the present application.

[0088] As a possible implementation, step S700 is executed only when the preset automatic adjustment function is enabled. Thus, the softness adjustment is avoided without the user's knowledge, and the driving safety is improved.

[0089] As a possible implementation, the step S200 performed first further comprises: based on the first parameter value, controlling the driving device to act so that the compression amount of the seat cushion is adjusted to the compression amount corresponding to the first parameter value at a first preset speed. The step S300 further comprises: after the first preset time elapses, based on the preset second parameter value, controlling the driving device to act so that the compression amount of the seat cushion is adjusted to the compression amount corresponding to the preset second parameter value at a second preset speed; wherein the first preset speed is greater than the second preset speed.

[0090] The first preset speed is relatively fast, so that the compression amount of the seat cushion can be adjusted quickly when the user just gets into the vehicle, and the user does not have to wait for a long time for the seat cushion to adjust, so that the user can quickly reach a comfortable state. After the first preset time elapses, the second preset speed is relatively slow, so that the compression amount of the seat cushion is adjusted slowly, avoiding the compression amount of the seat cushion changing suddenly when the user has already adapted to the initial seat state, so that the user feels uncomfortable. The relatively slow second preset speed can make the user's body have a relatively smooth transition process, avoiding the user feeling uncomfortable due to the sharp change of the seat state, so that the body can naturally adapt to the transition of the seat from the initial state conforming to the user's identity to the balanced state.

[0091] Further, after the second preset time elapses, the step S200 performed returns, and the compression amount of the seat cushion can be adjusted to the compression amount corresponding to the first parameter value at the second preset speed. The present application does not limit the specific values of the first preset speed and the second preset speed. For example, the first preset speed is 0.5 cm / s-2 cm / s, such as 1 cm / s, 1.5 cm / s, etc. The second preset speed is 0.05 cm / s-0.2 cm / s, such as 0.08 cm / s, 0.1 cm / s, etc.

[0092] As a possible implementation, the first preset time is greater than the second preset time. In the early stage of driving, the softness and hardness of the seat cushion conform to the user's identity information, so that the seat can reach an initial state conforming to the user and being relatively comfortable. Therefore, after the relatively long first preset time elapses, the compression amount corresponding to the preset second parameter value is switched to, so that fatigue is relieved by changing the softness and hardness of the seat. After the relatively short second preset time elapses, the seat cushion returns to the initial compression amount conforming to the user, so that the user's demand for the softness and hardness of the seat can be better met, and the user is more comfortable.

[0093] Possibly, the cycle of steps S200-S300 is exited when a preset end time is reached. The preset time can be set based on experiments or user preferences, etc. For example, the cycle of steps S200-S300 is exited after being executed for 1.5-8 hours. In a short trip, the preset time can be 2 hours, in a long trip, the preset time can be 7 hours, etc. In addition, the cycle can also be exited in the case that the preset automatic adjustment function is turned off.

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