[0001] The present invention relates to the technical field of vehicles, and particularly to a vehicle seat pressure adjustment method, an electronic device, a storage medium, and a computer program product. Background Art

[0002] A vehicle seat includes multiple parts, including the main surface of the backrest, the side wings of the backrest, the main surface of the seat cushion, the side wings of the seat cushion, the main surface of the leg rest, the main surface of the headrest, etc. In order to provide a comfortable riding experience for the occupant, the vehicle seats of existing vehicles will adjust the pressure of multiple parts.

[0003] For the adjustment of the vehicle seat in the prior art, each part is adjusted independently. However, some parts are pressure-related. For example, between the main surface of the seat cushion and the main surface of the backrest, when there is no pressure on the main surface of the seat cushion, there may be no one sitting, and independently adjusting the main surface of the backrest easily leads to inaccurate calculation of the target pressure. Summary of the Invention

[0044] The following further describes the specific embodiments of the present invention with reference to the drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0045] As Figure 1 shown is a working flowchart of a vehicle seat pressure adjustment method according to an embodiment of the present invention, including:

[0046] Step S101, calculating a first target pressure value of the first part according to a first current pressure value of the first part of the vehicle seat;

[0047] Step S102: According to the first target pressure value, control the actuation of the first part until the first pressure value of the first part reaches the first target pressure value or the first adjustment duration is greater than the first adjustment duration threshold, where the first adjustment duration is the duration of controlling the actuation of the first part.

[0048] Step S103: Detect whether the first pressure of the first part reaches the pressure threshold. When the first pressure reaches the threshold or the second detection duration exceeds the second detection duration threshold, calculate the second target pressure value of the second part of the vehicle seat according to the second current pressure value of the second part. The second part is pressure-related to the first part, and the second detection duration is the duration for detecting whether the first pressure of the first part reaches the pressure threshold.

[0049] Step S104: According to the second target pressure value, control the actuation of the second part until the second pressure value of the second part reaches the second target pressure value or the second adjustment duration is greater than the second adjustment duration threshold, where the second adjustment duration is the duration of controlling the actuation of the second part.

[0050] Specifically, the present invention can be applied to an electronic device with processing capabilities, such as a vehicle controller. For example, the electronic control unit (ECU) of a vehicle.

[0051] Among them, step S101 and step S103 can be executed in parallel, that is, while executing step S101, step S103 is executed. Step S101 and step S103 can also be executed sequentially, that is, steps S101 to S104 are executed in sequence.

[0052] First, execute step S101. According to the first current pressure value of the first part of the vehicle seat, calculate the first target pressure value of the first part.

[0053] Specifically, the vehicle seat includes multiple parts. Each part calculates the target pressure value of this part based on the current pressure value by using an existing calculation method to improve the comfort or support of the seat.

[0054] Among them, the target pressure value is the pressure value with the best user comfort. Calculating the target pressure value according to the current pressure value can be implemented by using an AI model such as a neural network algorithm. Specifically, for each part, a large number of sample populations with the best comfort pressure values are collected as training samples, and a neural network is trained for each part. The trained neural network receives the current pressure value of this part, identifies the user's body type and weight status, and outputs the predicted pressure value as the target pressure value of this part.

[0055] Among them, the seat includes at least two types of parts. The first type of part, hereinafter referred to as the first part, is the part used to determine whether a passenger is seated. The second type of part, hereinafter referred to as the second part, is the part that needs to be adjusted only after the passenger is seated. The seat may further include a third type of part, hereinafter referred to as the third part, which is the part that can be adjusted without determining whether the passenger is seated.

[0056] Among them, the parts of the seat include but are not limited to: the main surface of the backrest, the side wings of the backrest, the main surface of the seat cushion, the side wings of the seat cushion, the main surface of the leg rest, the main surface of the headrest, etc.

[0057] In some embodiments, the first part is: the main surface of the seat cushion; the second part is: the side wings of the seat cushion; the third part is: the main surface of the headrest.

[0058] In some embodiments, the first part is: the main surface of the seat cushion; the second part is: the main surface of the backrest; the third part is: the side wings of the backrest.

[0059] In some embodiments, the first part is: the main surface of the backrest; the second part is: the side wings of the backrest; the third part is: the main surface of the headrest.

[0060] In some embodiments, the first part is: the main surface of the seat cushion; the second part is: the main surface of the leg rest; the third part is: the side wings of the backrest.

[0061] In some embodiments, the first part is: the main surface of the seat cushion; the second part is: the main surface of the leg rest; the third part is: the main surface of the headrest.

[0062] The above embodiments are only for illustrative purposes and are not actually limited to the combinations of the above parts.

[0063] Then perform step S102. According to the first target pressure value, control the first part to act until the first pressure value of the first part reaches the first target pressure value or the first adjustment duration is greater than the first adjustment duration threshold. The first adjustment duration is the duration of controlling the first part to act.

[0064] Specifically, adopt the existing actuation control method to control the first part to act, and at the same time, monitor the first pressure value of the first part in real time. When the first pressure value reaches the first target pressure value, stop the first part from acting. Or when the actuation of the first part times out, that is, when the first adjustment duration of controlling the first part to act is greater than the first adjustment duration threshold, stop the first part from acting. Among them, the actuation is the actuation that makes the actual pressure value of the part approach the target pressure value, including two directions of pressure increase or decrease. For example, through a mechanical linkage or an airbag, a certain part of the seat is made to approach or move away from the human body to form a pressure change.

[0065] Meanwhile, step S103 is executed to detect whether the first pressure of the first part reaches a pressure threshold. When the first pressure reaches the threshold or the second detection duration exceeds the second detection duration threshold, the second target pressure value of the second part of the vehicle seat is calculated according to the second current pressure value of the second part. The pressure of the second part is associated with that of the first part, and the second detection duration is the duration for detecting whether the first pressure of the first part reaches the pressure threshold.

[0066] Specifically, both the second part and the first part are parts on the vehicle seat, and the pressure of the second part is associated with that of the first part. A table can be set up to record the pressure association between the first part and the second part.

[0067] Since the pressure of the first part is associated with that of the second part, after the pressure of the first part reaches the threshold or the detection duration times out, the second target pressure value of the second part is calculated for adjustment. Among them, the first part is used to determine whether a passenger is sitting, and the second part needs to be adjusted after the passenger sits. If the pressure of the first part (such as the main surface of the seat cushion) reaches the threshold, it is determined that the passenger has sat down, and the second part (such as the main surface of the backrest) can start to be adjusted; if not, it is determined that the passenger has not sat down, and the second part does not need to be adjusted. The second detection duration is the duration for detecting whether the first pressure of the first part reaches the pressure threshold.

[0068] After the pressure of the first part reaches the threshold and the second target pressure value is calculated, step S104 is executed. According to the second target pressure value, the second part is controlled to act until the second pressure value of the second part reaches the second target pressure value or the second adjustment duration is greater than the second adjustment duration threshold. The second adjustment duration is the duration for controlling the second part to act.

[0069] In some embodiments, the first pressure or the second pressure detected can be the body pressure of the contact surface between the passenger and the seat, the air pressure of the seat adjustment airbag, or other pressure parameters.

[0070] The present invention performs separate pressure adjustment on the first part of the vehicle seat, and only when the pressure of the first part reaches the pressure threshold, the pressure adjustment of the second part associated with the pressure of the first part is performed, ensuring the pressure correlation between the first part and the second part, and making the pressure adjustment of the second part more accurate.

[0071] As Figure 2 shown is the flowchart of a vehicle seat pressure adjustment method in another embodiment of the present invention, including:

[0072] Step S201, calculate the first target pressure value of the first part according to the first current pressure value of the first part of the vehicle seat.

[0073] In one embodiment, calculating the first target pressure value of the first part according to the first current pressure value of the first part of the vehicle seat includes:

[0074] Detecting whether the first pressure of the first part is stable. When the first pressure is stable or the first detection duration exceeds the first detection duration threshold, calculating the first target pressure value of the first part according to the first current pressure value of the first part of the vehicle seat, where the first detection duration is the duration for detecting whether the first pressure of the first part is stable.

[0075] In one embodiment, before controlling the first part to actuate according to the first target pressure value, it further includes: controlling the first part to pre-actuate.

[0076] Step S202, controlling the first part to actuate according to the first target pressure value until the first pressure value of the first part reaches the first target pressure value or the first adjustment duration is greater than the first adjustment duration threshold. The first adjustment duration is the duration for controlling the first part to actuate. During the process of controlling the first part to actuate, continuously monitor the first pressure value. If the first pressure value is less than the pressure threshold, control the first part to stop actuating.

[0077] In one embodiment, it further includes: adjusting the first target pressure value according to the first adjustment duration during the process of controlling the first part to actuate.

[0078] In one embodiment, it further includes: obtaining the body type information of the occupant on the vehicle seat and determining the pressure threshold according to the body type information.

[0079] Step S203, detecting whether the first pressure of the first part reaches the pressure threshold. When the first pressure reaches the threshold or the second detection duration exceeds the second detection duration threshold, calculating the second target pressure value of the second part according to the second current pressure value of the second part of the vehicle seat. The second part is pressure-related to the first part, and the second detection duration is the duration for detecting whether the first pressure of the first part reaches the pressure threshold.

[0080] In one embodiment, before controlling the second part to actuate according to the second target pressure value, it further includes: controlling the second part to pre-actuate.

[0081] Step S204: According to the second target pressure value, control the actuation of the second part until the second pressure value of the second part reaches the second target pressure value or the second adjustment duration is greater than the second adjustment duration threshold. The second adjustment duration is the duration of controlling the actuation of the second part. During the process of controlling the actuation of the second part, continuously monitor the first pressure value. If the first pressure value is less than the pressure threshold, control the second part to stop actuating.

[0082] In one embodiment, it further includes: during the process of controlling the actuation of the second part, adjust the second target pressure value according to the second adjustment duration.

[0083] Step S205: Calculate the third target pressure value of the third part of the vehicle seat according to the third current pressure value of the third part. The third part has nothing to do with the pressure of the first part.

[0084] In one embodiment, before controlling the actuation of the third part according to the third target pressure value, it further includes: controlling the third part to pre-actuate.

[0085] Step S206: According to the third target pressure value, control the actuation of the third part until the third pressure value of the third part reaches the third target pressure value or the third adjustment duration is greater than the third adjustment duration threshold. The third adjustment duration is the duration of controlling the actuation of the third part.

[0086] In one embodiment, it further includes: during the process of controlling the actuation of the third part, adjust the third target pressure value according to the third adjustment duration.

[0087] Specifically, there are multiple adjustment parts on the vehicle seat in this embodiment, which can be classified into the first part, the second part, and the third part. Among them, for the first part, after the initial pressure is stable, calculate the target pressure for adjustment. The pressure of the second part is related to the pressure of the first part. After the pressure of the first part reaches the threshold, calculate the target pressure for adjustment. The third part can directly calculate the target pressure for adjustment according to the current initial pressure. Among them, the number of the first part ≥ 1, the number of the second part ≥ 1, and the number of the third part ≥ 0.

[0088] In some embodiments, the pressure can be the body pressure of the contact surface between the passenger and the seat, the air pressure of the seat adjustment airbag, or other pressure parameters.

[0089] The pressure can be detected by pressure sensors provided on each part.

[0090] Step S201, step S203, and step S205 can be executed in parallel or sequentially. That is, the first part, the second part, and the third part can be controlled in parallel, or the first part, the second part, and the third part can be executed sequentially.

[0091] Among them, when executing step S201, according to the first current pressure value of the first part of the vehicle seat, calculate the first target pressure value of the first part.

[0092] In one embodiment, the calculating the first target pressure value of the first part according to the first current pressure value of the first part of the vehicle seat includes:

[0093] Detect whether the first pressure of the first part is stable. When the first pressure is stable or the first detection duration exceeds the first detection duration threshold, calculate the first target pressure value of the first part according to the first current pressure value of the first part of the vehicle seat. The first detection duration is the duration for detecting whether the first pressure of the first part is stable.

[0094] Specifically, after waiting for the pressure of the first part to be stable or waiting for the time to exceed the limit, calculate the first target pressure value of the first part according to the first current pressure of the first part, and then perform adjustment. Among them, "waiting for the pressure to be stable" is an optional method. In the case of a seat with a thick buffer sponge or airbag, after the passenger sits down and makes contact, it is in a reciprocating rebound process. Therefore, for some seat conditions, the pressure takes a certain time to be stable and the collected readings will be accurate.

[0095] In one embodiment, before controlling the first part to actuate according to the first target pressure value, it further includes: controlling the first part to pre-actuate.

[0096] The first part can perform certain pre-actuation before adjusting according to the first target pressure value, so as to reduce the total adjustment duration and the passenger waiting time or enhance the passenger perception experience. The pre-actuation includes but is not limited to: pre-tightening, pre-ejecting, pre-extending, reciprocating tightening / relaxing, reciprocating ejecting / retracting, reciprocating extending / contracting, etc.

[0097] In some embodiments, after calculating the first target pressure value of the first part according to the first current pressure value of the first part of the vehicle seat, and before controlling the first part to actuate according to the first target pressure value, control the first part to pre-actuate.

[0098] Since calculating the first target pressure value requires waiting for the pressure at the first part to stabilize, in order to avoid the pre-actuation affecting the pressure stability, after calculating the first target pressure value of the first part based on the first current pressure value of the first part of the vehicle seat and before controlling the actuation of the first part according to the first target pressure value, the pre-actuation of the first part is controlled.

[0099] Then step S202 is executed to control the actuation of the first part according to the first target pressure value until the first pressure value of the first part reaches the first target pressure value or the first adjustment duration is greater than the first adjustment duration threshold. The first adjustment duration is the duration of controlling the actuation of the first part. During the process of controlling the actuation of the first part, the first pressure value is continuously monitored. If the first pressure value is less than the pressure threshold, the actuation of the first part is controlled to stop.

[0100] Specifically, the pressure change during the adjustment process should be continuous. In the prior art for the adjustment of a part, after determining the target pressure, the adjustment will continue until the pressure detected by the part reaches the target pressure. However, the pressure detected by the part is adjusted based on the force exerted by the human body on the part. When the human body leaves the part and does not exert force on the part, the pressure detected by the part will change suddenly. At this time, continuing the adjustment will lead to inaccurate adjustment. For example, when there is suddenly no pressure on the main surface of the seat cushion, continuing to adjust the main surface of the seat cushion is likely to result in inaccurate adjustment.

[0101] Therefore, in this embodiment, during the process of adjusting the first part, it is dynamically determined whether the first pressure value reaches the pressure threshold, whether the first pressure value reaches the first target pressure value, and whether the adjustment duration of the first part times out, and corresponding adjustment, stop, completion and other actions are executed. If the first pressure value of the first part does not reach the pressure threshold during the adjustment process, it indicates that the first pressure value has changed suddenly, which means that the human body has left the first part. At this time, the adjustment is stopped to avoid inaccurate adjustment.

[0102] In one of the embodiments, it further includes: during the process of controlling the actuation of the first part, adjusting the first target pressure value according to the first adjustment duration.

[0103] Specifically, the adjusting the first target pressure value according to the first adjustment duration includes:

[0104] Adjusting the tolerance width of the first target pressure value according to the first adjustment duration, and the tolerance width of the first target pressure value is positively correlated with the first adjustment duration.

[0105] Specifically, as long as the first pressure value is within the range of the first target pressure value ± the tolerance width, the adjustment is stopped. The longer the first adjustment duration, the wider the allowable tolerance, and the easier it is for the first pressure value to enter the range of the first target pressure value ± the tolerance width, facilitating the completion of the adjustment as soon as possible.

[0106] In this embodiment, to avoid the first part from repeatedly adjusting and unable to stop, a dynamic target pressure value is set, that is, the magnitude of the first target pressure value changes with the first adjustment duration, so that the first pressure value of the first part can quickly reach the first target pressure value.

[0107] In one of the embodiments, it further includes: obtaining the body size information of the occupant on the vehicle seat, and determining the pressure threshold according to the body size information.

[0108] Specifically, the passenger body size can be accurately identified through sensors or cameras, or the passenger body size information can be preset in advance.

[0109] In this embodiment, according to the body size information, the target such as the pressure threshold is dynamically adjusted to improve the judgment accuracy. Among them, multiple groups of body size information and corresponding pressure thresholds can be pre-calibrated, and the corresponding relationship between the body size information and the pressure threshold can be determined through a table or fitting method. Then, after obtaining the current body size information of the occupant, the corresponding pressure threshold is obtained by inputting it into the table, or the fitting function obtained through fitting is output to obtain the corresponding pressure threshold.

[0110] Execute step S203 to detect whether the first pressure of the first part reaches the pressure threshold. When the first pressure reaches the threshold or the second detection duration exceeds the second detection duration threshold, calculate the second target pressure value of the second part of the vehicle seat according to the second current pressure value of the second part. The second part is pressure-related to the first part, and the second detection duration is the duration for detecting whether the first pressure of the first part reaches the pressure threshold.

[0111] Specifically, after the second part waits for the pressure of the first part to reach the pressure threshold or after the waiting time expires, calculate the second target pressure value of the second part according to the second current pressure of the second part, and then perform the adjustment.

[0112] In one of the embodiments, before controlling the second part to act according to the second target pressure value, it further includes: controlling the second part to pre-actuate.

[0113] Specifically, the second part can perform a certain pre-actuation before adjusting according to the second target pressure value to reduce the total adjustment duration and the passenger waiting time or enhance the passenger perception experience. The pre-actuation includes but is not limited to: pre-tightening, pre-ejecting, pre-extending, reciprocating tightening / relaxing, reciprocating ejecting / retracting, reciprocating extending / contracting, etc.

[0114] In some embodiments, before calculating the second target pressure value of the second part of the vehicle seat according to the second current pressure value of the second part, the second part is controlled to be pre-activated.

[0115] In some embodiments, after calculating the second target pressure value of the second part of the vehicle seat according to the second current pressure value of the second part and before controlling the second part to actuate according to the second target pressure value, the second part is controlled to be pre-activated.

[0116] Then step S204 is executed to control the second part to actuate according to the second target pressure value until the second pressure value of the second part reaches the second target pressure value or the second adjustment duration is greater than the second adjustment duration threshold. The second adjustment duration is the duration of controlling the second part to actuate. During the process of controlling the second part to actuate, the first pressure value is continuously monitored. If the first pressure value is less than the pressure threshold, the second part is controlled to stop actuating.

[0117] Specifically, during the adjustment process, it is dynamically determined whether the first pressure value of the first part reaches the pressure threshold, whether the second pressure of the second part reaches the second target pressure value, and whether the second adjustment duration of the second part actuating times out, and corresponding adjustment, stop, completion and other actions are performed. Among them, during the actuating process of the second part, the first pressure value of the first part is monitored in real time. Once the first pressure value is less than the pressure threshold, it means that the human body has left the first part. At this time, there is no need to continue actuating the second part, so the second part is controlled to stop actuating.

[0118] In one of the embodiments, it further includes: during the process of controlling the second part to actuate, the second target pressure value is adjusted according to the second adjustment duration.

[0119] Specifically, the adjusting the second target pressure value according to the second adjustment duration includes:

[0120] Adjusting the tolerance width of the second target pressure value according to the second adjustment duration, and the tolerance width of the second target pressure value is positively correlated with the second adjustment duration.

[0121] Specifically, as long as the second pressure value is within the range of the second target pressure value ± the tolerance width, the adjustment is stopped. The longer the second adjustment duration is, the wider the allowable tolerance is, and the second pressure value is more likely to enter the range of the second target pressure value ± the tolerance width, which is convenient for completing the adjustment as soon as possible.

[0122] In this embodiment, in order to prevent the second part from being repeatedly adjusted and actuated and unable to stop, a dynamic target pressure value is set, that is, the magnitude of the second target pressure value changes with the second adjustment duration, so that the second pressure value of the second part quickly reaches the second target pressure value.

[0123] Execute step S205, calculate the third target pressure value of the third part according to the third current pressure value of the third part of the vehicle seat, and the third part has nothing to do with the pressure of the first part.

[0124] Specifically, the third part calculates the third target pressure value according to the third current pressure value of the third part, and then makes an adjustment.

[0125] In one embodiment, before controlling the third part to act according to the third target pressure value, it further includes: controlling the third part to pre-actuate.

[0126] Specifically, the third part can perform a certain pre-actuation before adjusting according to the third target pressure value to reduce the total adjustment duration and the passenger waiting time or enhance the passenger perception experience. The pre-actuation includes but is not limited to: pre-tightening, pre-ejecting, pre-extending, reciprocating tightening / relaxing, reciprocating ejecting / retracting, reciprocating extending / contracting, etc.

[0127] In some embodiments, before calculating the third target pressure value of the third part according to the third current pressure value of the third part of the vehicle seat, control the third part to pre-actuate.

[0128] In some embodiments, after calculating the third target pressure value of the third part according to the third current pressure value of the third part of the vehicle seat, and before controlling the third part to act according to the third target pressure value, control the third part to pre-actuate.

[0129] Then execute step S206, control the third part to act according to the third target pressure value until the third pressure value of the third part reaches the third target pressure value or the third adjustment duration is greater than the third adjustment duration threshold, and the third adjustment duration is the duration of controlling the third part to act.

[0130] Specifically, during the adjustment process, dynamically judge whether the third pressure value reaches the third target pressure value and whether the third adjustment duration of controlling the third part to act times out, and perform corresponding adjustment, completion and other actions.

[0131] In this embodiment, the first part of the vehicle seat is adjusted separately in terms of pressure, and when the pressure of the first part reaches the pressure threshold, the second part associated with the pressure of the first part is adjusted in terms of pressure, ensuring the pressure correlation between the first part and the second part and making the pressure adjustment of the second part more accurate. At the same time, during the adjustment process of the first part and the second part, continuously monitor the pressure of the first part to avoid ineffective adjustment of the first part and the second part when the first part has no pressure. At the same time, the third part that has nothing to do with the pressure of the first part is adjusted separately.

[0132] In one embodiment, it further includes: during the process of controlling the actuation of the third part, adjusting the third target pressure value according to the third adjustment duration.

[0133] Specifically, the adjusting the third target pressure value according to the third adjustment duration includes:

[0134] Adjusting the tolerance width of the third target pressure value according to the third adjustment duration, and the tolerance width of the third target pressure value is positively correlated with the third adjustment duration.

[0135] Specifically, as long as the third pressure value is within the range of the third target pressure value ± tolerance width, the adjustment is stopped. The longer the third adjustment duration is, the wider the allowable tolerance is, and the third pressure value is more likely to enter the range of the third target pressure value ± tolerance width, which is convenient for completing the adjustment as soon as possible.

[0136] In this embodiment, to avoid the third part from repeatedly adjusting and actuating without stopping, a dynamic target pressure value is set, that is, the magnitude of the third target pressure value changes with the third adjustment duration, so that the third pressure value of the third part quickly reaches the third target pressure value.

[0137] As Figure 3 shown is a flowchart of a method for adjusting the pressure of a vehicle seat according to the best embodiment of the present invention, including:

[0138] Step S311, whether the pressure of the first part is stable. If it is, execute step S313; otherwise, execute step S312.

[0139] Step S312, whether the waiting time t1 times out. If it is, execute step S313; otherwise, continue to execute step S311.

[0140] Step S313, calculating the target pressure value according to the current pressure value of the first part.

[0141] Step S314, pre-actuating the first part.

[0142] Step S315, whether the pressure of the first part reaches the threshold value. If it is, execute step S316; otherwise, the first part stops actuating and continues to execute step S315.

[0143] Step S316, whether the pressure of the first part reaches the target value. If it is, the adjustment of the first part is completed and ended; otherwise, execute step S317.

[0144] Step S317, whether the adjustment time of the first part is less than the upper limit value. If it is, the first part adjusts and actuates, and execute step S315; otherwise, the adjustment of the first part is completed and ended.

[0145] Step S321: Check if the pressure at the first part reaches the threshold. If yes, execute Step S323; otherwise, execute Step S322.

[0146] Step S322: Check if the waiting time t2 has timed out. If yes, execute Step S323; otherwise, continue to execute Step S321.

[0147] Step S323: Pre-actuate the second part.

[0148] Step S324: Calculate the target pressure value based on the current pressure value of the second part.

[0149] Step S325: Check if the pressure at the first part reaches the threshold. If yes, execute Step S316; otherwise, stop the actuation of the second part and continue to execute Step S325.

[0150] Step S326: Check if the pressure at the second part reaches the target value. If yes, the adjustment of the second part is completed and end; otherwise, execute Step S327.

[0151] Step S327: Check if the adjustment time of the second part is less than the upper limit value. If yes, the second part adjusts and actuates, and execute Step S325; otherwise, the adjustment of the second part is completed and end.

[0152] Step S331: Pre-actuate the third part.

[0153] Step S332: Calculate the target pressure value based on the current pressure value of the third part.

[0154] Step S333: Check if the pressure at the third part reaches the target value. If yes, the adjustment of the third part is completed and end; otherwise, execute Step S334.

[0155] Step S334: Check if the adjustment time of the third part is less than the upper limit value. If yes, the third part adjusts and actuates, and execute Step S333; otherwise, the adjustment of the third part is completed and end.

[0156] Specifically, there are three types of adjustment parts on the seat, namely the first part, the second part, and the third part.

[0157] In this embodiment, for the first part, after the initial pressure is stable, the target pressure is calculated for adjustment. The pressure of the second part is related to the pressure of the first part. After the pressure of the first part reaches the threshold, the target pressure is calculated for adjustment. The third part can directly calculate the target pressure for adjustment based on the current initial pressure.

[0158] Optionally, the pressure can be the body pressure of the contact surface between the passenger and the first part, the second part, and the third part, or the air pressure of the adjustment airbags of the first part, the second part, and the third part, or other pressure parameters.

[0159] Steps S311, S321, and S331 can be executed in parallel or sequentially. That is, the first part, the second part, and the third part can be adjusted synchronously or in a certain order, such as the first part → the second part → the third part.

[0160] Optionally, before adjusting according to the target pressure, the first part, the second part, and the third part can perform a certain pre-actuation. The pre-actions of each part can be set with different time sequences and durations respectively.

[0161] Steps S311 to S317 are used to control the first part.

[0162] Specifically, after the first part waits for the pressure to stabilize or the waiting time times out, it calculates the target pressure based on the current pressure, and then makes an adjustment. During the adjustment process, it dynamically judges whether the pressure reaches the threshold, whether the pressure reaches the target value, and whether the adjustment duration times out, and performs corresponding adjustment, stop, completion and other actions.

[0163] Steps S321 to S327 control the second part.

[0164] Specifically, after the second part waits for the pressure of the first part to reach the threshold or the waiting time times out, it calculates the target pressure based on the current pressure, and then makes an adjustment. During the adjustment process, it dynamically judges whether the pressure of the first part reaches the threshold, whether the pressure of the second part reaches the target value, and whether the adjustment duration times out, and performs corresponding adjustment, stop, completion and other actions.

[0165] Steps S331 to S334 control the third part.

[0166] Specifically, the third part calculates the target pressure based on the current pressure, and then makes an adjustment. During the adjustment process, it dynamically judges whether the pressure reaches the target value and whether the adjustment duration times out, and performs corresponding adjustment, completion and other actions.

[0167] Optionally, to prevent the first part, the second part, and the third part from repeatedly adjusting and actuating without stopping, a dynamic target value (the size changes with the adjustment duration) can be set to enable the pressure to quickly reach the target value.

[0168] Optionally, if the passenger's body type is accurately identified through a sensor or a camera, or the passenger's body type information is preset in advance, the targets such as "whether the pressure reaches the threshold" can be dynamically adjusted to improve the judgment accuracy.

[0169] Calculating the target pressure value based on the current pressure value can be implemented using an AI model such as a neural network algorithm.

[0170] In one of the embodiments, it further includes:

[0171] After the first pressure value reaches the first target pressure value, if it is detected that the first pressure value is less than the first target pressure value minus the first lower follow-up threshold, or the first pressure value is greater than the first target pressure value plus the first upper follow-up threshold, then control the first part to act until the first pressure value of the first part reaches the first target pressure value or the first adjustment duration is greater than the first adjustment duration threshold; or

[0172] After the second pressure value reaches the second target pressure value, if it is detected that the second pressure value is less than the second target pressure value minus the second lower follow-up threshold, or the second pressure value is greater than the second target pressure value plus the second upper follow-up threshold, then control the second part to act until the second pressure value of the second part reaches the second target pressure value or the second adjustment duration is greater than the second adjustment duration threshold; or

[0173] After the third pressure value reaches the third target pressure value, if it is detected that the third pressure value is less than the third target pressure value minus the third lower follow-up threshold, or the third pressure value is greater than the third target pressure value plus the third upper follow-up threshold, then control the third part to act until the third pressure value of the third part reaches the third target pressure value or the third adjustment duration is greater than the third adjustment duration threshold.

[0174] Specifically, after the adjustment of the first part is completed, continue to monitor the first pressure value of the first part. If it is detected that the first pressure value is less than the first target pressure value minus the first lower follow-up threshold, or the first pressure value is greater than the first target pressure value plus the first upper follow-up threshold, then control the first part to act and readjust it to the first target pressure value. Among them, the first lower follow-up threshold and the first upper follow-up threshold are not necessarily the same.

[0175] In some embodiments, obtain the occupant posture or the type of occupant movement, and set the first lower follow-up threshold and the first upper follow-up threshold according to the occupant posture or the type of occupant movement.

[0176] After the adjustment of the second part is completed, continue to monitor the second pressure value of the second part. If it is detected that the second pressure value is less than the second target pressure value minus the second lower follow-up threshold, or the second pressure value is greater than the second target pressure value plus the second upper follow-up threshold, then control the second part to act and readjust it to the second target pressure value. Among them, the second lower follow-up threshold and the second upper follow-up threshold are not necessarily the same.

[0177] In some embodiments, obtain the occupant posture or the type of occupant movement, and set the second lower follow-up threshold and the second upper follow-up threshold according to the occupant posture or the type of occupant movement.

[0178] After the adjustment of the third part is completed, continue to monitor the third pressure value of the third part. If it is detected that the third pressure value is less than the third target pressure value minus the third lower follow-up threshold, or the third pressure value is greater than the third target pressure value plus the third upper follow-up threshold, then control the third part to actuate and readjust to the third target pressure value. Among them, the third lower follow-up threshold and the third upper follow-up threshold are not necessarily the same.

[0179] Among them, the first part, the second part, and the third part can all follow up, that is, under conditions such as when the passenger adjusts the sitting posture and takes a long ride, the pressure changes, and each part can be adjusted and actuated to return to the target pressure.

[0180] Among them, when the occupant adjusts the sitting posture, takes a long ride and other conditions, the pressure may increase or decrease. Therefore, an upper follow-up threshold for judging whether the pressure increase exceeds the limit and a lower follow-up threshold for judging whether the pressure decrease exceeds the limit are respectively set. The upper follow-up threshold and the lower follow-up threshold are set independently, and different triggering sensitivities can be realized according to the follow-up function when the pressure increases or decreases. Multiple (≥2) parts can follow up simultaneously.

[0181] In some embodiments, the occupant posture or the occupant action type is obtained, and the third lower follow-up threshold and the third upper follow-up threshold are set according to the occupant posture or the occupant action type.

[0182] Among them, the occupant posture or the occupant action type can be judged according to the shooting of the occupant by the in-vehicle camera device or the detection of multiple pressure sensors on the seat.

[0184] Step S401, the pressure has been adjusted to the target pressure value;

[0185] Step S402, monitor whether the pressure changes;

[0186] Step S403, if the pressure is less than the target pressure value - the lower follow-up threshold, then execute step S405, otherwise execute step S404;

[0187] Step S404, if the pressure is greater than the target pressure value + the upper limit follow-up threshold, then execute Step S406; otherwise, execute Step S402;

[0188] Step S405, perform part adjustment actuation. If the pressure reaches the target value, then execute Step S402; otherwise, continue to execute Step S405;
