[0009] If the fatigue state of the user's body part corresponding to the sub-region is the fatigued state, the sub-region is controlled to move to relieve fatigue of the user's body part corresponding to the sub-region.

[0010] According to the above technical means, in the process of controlling the seat, the fatigue state of the user's body part corresponding to the sub-region is first determined, so that the fatigue state of the user's body can be determined more accurately. Further, if the fatigue state of the user's body part corresponding to the sub-region is the fatigued state, the sub-region is controlled to move to relieve the fatigue of the user's body part corresponding to the sub-region, so that the fatigue state of the specific part of the user's body can be relieved more accurately and efficiently, thereby improving the accuracy of seat control and user experience.

[0011] Further, determining a first pressure parameter of a sub-region of the vehicle seat includes:

[0012] Collecting first pressure data of the sub-area in a first time period, and collecting second pressure data of the sub-area in a second time period; wherein the first time period is a time period after the vehicle starts to travel and after the vehicle speed exceeds a preset threshold within a preset time period; the second time period is a time period after the first time period;

[0013] A first pressure parameter of the sub-region is determined according to the first pressure data and the second pressure data.

[0014] According to the above-mentioned technical means, the first pressure data collected in the first time period is used as a reference basis, and the first pressure parameter used to determine the fatigue state of the user's body part corresponding to the sub-area is determined according to the second data collected in the second time period. This can improve the accuracy of the determined fatigue state of the user's body part and further improve the accuracy of the seat control.

[0015] Further, determining a first pressure parameter of the sub-region according to the first pressure data and the second pressure data includes:

[0076] The technical solution of the present invention is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0077] Figure 1 The process of the seat control method provided by one embodiment of the present invention is as follows Figure 1 .like Figure 1 As shown, the method of the embodiment of the present invention includes:

[0078] Step S101: during vehicle driving, determining a first pressure parameter of a sub-region of a vehicle seat, and determining a fatigue state of a user's body part corresponding to the sub-region based on the first pressure parameter of the sub-region.

[0079] Specifically, during the driving process of the vehicle, the first pressure parameter of each sub-area of ​​the vehicle seat can be determined, and based on the first pressure parameter of the sub-area, the fatigue state of the user's body part corresponding to each sub-area can be determined. The sub-area of ​​the vehicle seat refers to the sub-area of ​​the vehicle seat corresponding to different user's body parts, wherein the present invention does not limit the sub-area of ​​the vehicle seat, and any sub-area of ​​the vehicle seat corresponding to different user's body parts can be used as the sub-area of ​​the vehicle seat provided by the present invention. Optionally, the vehicle seat to be controlled may include five sub-areas of the vehicle seat, for example: it may include a sub-area corresponding to the shoulder, a sub-area corresponding to the back, a sub-area corresponding to the waist, a sub-area corresponding to the buttocks, and a sub-area corresponding to the leg.

[0080] Wherein, the first pressure parameter is a pressure-related parameter used to determine the fatigue state of the user's body part corresponding to the sub-area, wherein the present invention does not limit the first pressure parameter, and any pressure-related parameter that can be used to determine the fatigue state of the user's body part corresponding to the sub-area can be used as the first pressure parameter provided by the present invention. Wherein, the present invention does not limit the process of determining the first pressure parameter of the sub-area of ​​the vehicle seat, wherein the process of determining the first pressure parameter of the sub-area of ​​the vehicle seat corresponds to the first pressure parameter provided by the present invention. Optionally, the first pressure data borne by the sub-area in the first time period can be collected first, and the second pressure data borne by the sub-area in the second time period can be collected; then, the first pressure parameter of the sub-area is determined based on the first pressure data and the second pressure data. Wherein, the first time period is a time period after the vehicle starts to travel and after the vehicle speed is greater than a preset threshold within a preset time period; the second time period is a time period located after the first time period.

[0081] Wherein, the fatigue state of the user's body part corresponding to the sub-region includes a fatigued state and a non-fatigued state; that is, the fatigue state of the user's body part corresponding to the sub-region is that the fatigue state of the user's body part corresponding to the sub-region is a fatigued state, or the fatigue state of the user's body part corresponding to the sub-region is a non-fatigued state. Wherein, the present invention does not limit the process of determining the fatigue state of the user's body part corresponding to the sub-region according to the first pressure parameter of the sub-region, wherein the process of determining the fatigue state of the user's body part corresponding to the sub-region according to the first pressure parameter of the sub-region corresponds to the first pressure parameter provided by the present invention. Optionally, if the first pressure parameter includes at least one first sub-pressure parameter, the process of determining the fatigue state of the user's body part corresponding to the sub-region according to the first pressure parameter of the sub-region may include: if it is determined that at least one of the at least one first sub-pressure parameter included in the first pressure parameter exceeds a preset threshold, then the fatigue state of the user's body part corresponding to the sub-region is determined to be a fatigued state; otherwise, the fatigue state of the user's body part corresponding to the sub-region is determined to be a non-fatigued state.

[0082] Step S102: If the fatigue state of the user's body part corresponding to the sub-region is already in a fatigued state, control the sub-region to move to relieve the fatigue of the user's body part corresponding to the sub-region.

[0083] Specifically, if the fatigue state of the user's body part corresponding to the sub-region determined in step S101 is already in a fatigued state, the sub-region is controlled to move to relieve fatigue of the user's body part corresponding to the sub-region.

[0084] Among them, the present invention does not limit the process of controlling the sub-region to move if the fatigue state of the user's body part corresponding to the sub-region is already in a fatigued state to relieve the fatigue of the user's body part corresponding to the sub-region. Any process of controlling the sub-region to move if the fatigue state of the user's body part corresponding to the sub-region is already in a fatigued state to relieve the fatigue of the user's body part corresponding to the sub-region can be used as the process of controlling the sub-region to move if the fatigue state of the user's body part corresponding to the sub-region is already in a fatigued state to relieve the fatigue of the user's body part corresponding to the sub-region provided by the present invention. Optionally, if the fatigue state of the user's body part corresponding to the sub-region is already in a fatigued state, it can be determined whether the sub-region is a designated area. If it is determined that the sub-region is a designated sub-region, the step of controlling the sub-region to move is executed.

[0085] The seat control method provided by the embodiment of the present invention determines a first pressure parameter of a sub-area of ​​a vehicle seat during vehicle driving, and determines the fatigue state of a user's body part corresponding to the sub-area based on the first pressure parameter of the sub-area; if the fatigue state of the user's body part corresponding to the sub-area is already in a fatigued state, the sub-area is controlled to move to relieve the fatigue of the user's body part corresponding to the sub-area. In the process of controlling the seat, the fatigue state of the user's body part corresponding to the sub-area is first determined, so that the fatigue condition of the user's body can be determined more accurately; further, if the fatigue state of the user's body part corresponding to the sub-area is already in a fatigued state, the sub-area is controlled to move to relieve the fatigue of the user's body part corresponding to the sub-area, so that the fatigue condition of the specific part of the user's body can be relieved more accurately and efficiently, thereby improving the accuracy of seat control and user experience.

[0086] Figure 2 The process of the seat control method provided by one embodiment of the present invention is Figure 2 .exist Figure 1 Based on the embodiment shown in FIG. 1 , this embodiment further describes the process of determining the first pressure parameter of the sub-region of the vehicle seat. Figure 2 As shown, the method of the embodiment of the present invention includes:

[0087] Step S201: collecting first pressure data borne by the sub-area in a first time period, and collecting second pressure data borne by the sub-area in a second time period.

[0088] Specifically, the first pressure data borne by the sub-area within the first time period can be collected, wherein the first time period is a time period after the vehicle starts to travel and after the vehicle speed is greater than a preset threshold within a preset time period. The present invention does not limit the preset time period corresponding to the process of collecting the first pressure data, and can optionally be one minute. The present invention does not limit the preset threshold value that the vehicle speed is greater than within the preset time period corresponding to the process of collecting the first pressure data, and can optionally be 20km / h. In the process of collecting the first pressure data, the purpose of setting the preset time period and the preset threshold value of the vehicle speed is to determine that the vehicle where the seat to be controlled is located has been in a driving state for more than a certain time, that is, the vehicle where the seat to be controlled is located has been stably in a driving state. The present invention does not limit the duration of the time period corresponding to the first time period, and can optionally be 5 minutes.

[0089] The first pressure data is data characterizing the pressure borne by the sub-area in the first time period, wherein the present invention does not limit the first pressure data, and any data that can characterize the pressure borne by the sub-area in the first time period can be used as the first pressure data provided by the present invention. Optionally, if the description of the sub-area of ​​the vehicle seat is as shown in step S101, the first pressure data can be the pressure value corresponding to multiple pressure points in the sub-area in the first time period, wherein the present invention does not limit the number of pressure points included in each sub-area, and optionally, the number of pressure points included in the sub-area corresponds to the body part of the user corresponding to the sub-area, and if the body part of the user corresponding to the sub-area is larger in area, the number of pressure points corresponding to the sub-area is larger, and conversely, if the body part of the user corresponding to the area is smaller in area, the number of pressure points corresponding to the sub-area is smaller.

[0090] Wherein, the second time period is a time period after the first time period. Wherein, the present invention does not limit the second time period, and any time period after the first time period can be used as the second time period provided by the present invention. Wherein, the second time period can be a time period after a preset time length after the first time period, wherein the present invention does not limit the preset time length corresponding to the process of collecting the second pressure data, and optionally, it can be 30 minutes, wherein, in the process of collecting the second pressure data, the purpose of setting the preset time length is that within the preset time length after the first time period, it is assumed that the user has not generated driving fatigue, so there is no need to collect the second pressure data, and determine the first pressure parameter of the sub-area. Wherein, the present invention does not limit the time length of the time period corresponding to the second time period, and optionally, it can be equal to the time length of the time period corresponding to the first time period, for example: if the time length of the time period corresponding to the first time period is five minutes, then the time length of the time period corresponding to the second time period is also 5 minutes, and optionally, it can be not equal to the time length of the time period corresponding to the first time period, for example: if the time length of the time period corresponding to the first time period is 5 minutes, then the time length of the time period corresponding to the second time period can be 6 minutes.

[0091] The second pressure data is data representing the pressure borne by the sub-area in the second time period. For the description of the second pressure data, reference can be made to the above description of the first pressure data, which will not be repeated here.

[0092] Step S202: Determine a first pressure parameter of the sub-region according to the first pressure data and the second pressure data.

[0093] Specifically, according to the first pressure data and the second pressure data collected in step S201, the first pressure parameter of the sub-area can be determined. For the description of the first pressure parameter, reference can be made to the description in step S101, which will not be repeated here.

[0094] The present invention does not limit the process of determining the first pressure parameter of the sub-area based on the first pressure data and the second pressure data. Optionally, the first pressure feature set of the sub-area can be determined based on the first pressure data, and the second pressure feature set of the sub-area can be determined based on the second pressure data. Then, the first pressure parameter of the sub-area is determined based on the first pressure feature value included in the first pressure feature set and the second pressure feature value included in the corresponding second pressure feature set. The first pressure feature set includes at least one first pressure feature value. The second pressure feature set includes at least one second pressure feature value. The first pressure feature value corresponds to the second pressure feature value one by one.

[0095] Among them, in the process of determining the first pressure parameter of the sub-area based on the first pressure data and the second pressure data, at least one pressure characteristic value corresponding to each pressure data is first determined respectively, so that the characteristics of the first pressure data and the second pressure data can be extracted more accurately, and then the first pressure parameter of the sub-area is determined based on the first pressure characteristic value included in the first pressure characteristic set and the second pressure characteristic value included in the corresponding second pressure characteristic set, which can further improve the accuracy of the determined first pressure parameter.

[0096] Among them, the present invention does not limit the first pressure feature set. Any feature set that can characterize the pressure characteristics of the first pressure data and can determine the first pressure parameters of the sub-area can be used as the first pressure feature set provided by the present invention. Correspondingly, the present invention does not limit the first pressure characteristic value included in the first pressure feature set. Optionally, the first pressure characteristic value can be one of the first maximum value characteristic value, the first average value characteristic value, the first symmetry value characteristic value, the first load-bearing value characteristic value, and the first pressure distribution value characteristic value.

[0097] The first maximum characteristic value refers to the characteristic value corresponding to the maximum pressure value corresponding to the first pressure data, wherein the maximum pressure value The calculation formula is as follows:

[0098]

[0099] Where n is the total number of non-zero pressure points in the sub-region, is the pressure value corresponding to the nth pressure point in the area.

[0100] The first average characteristic value refers to the characteristic value corresponding to the average pressure value corresponding to the first pressure data, wherein the average pressure value The calculation formula is as follows:

[0110] Optionally, after obtaining the first pressure characteristic value, the obtained first pressure characteristic value may be subjected to a de-excitation value operation to improve the accuracy of the first pressure characteristic value. The present application does not limit the process of performing a de-excitation value operation on the obtained first pressure characteristic value. Optionally, the obtained first pressure characteristic value may be subjected to a de-excitation value operation based on a standard deviation and a rate of change. When the type of the first pressure characteristic value is different, the threshold for performing a de-excitation value operation on the obtained first pressure characteristic value based on the standard deviation and the rate of change is different.

[0111] Optionally, if the first pressure characteristic value is the first maximum characteristic value, or the first average characteristic value, the time period threshold for de-escalating the acquired first pressure characteristic value according to the standard deviation and the rate of change is the first time period threshold, the standard deviation deviation threshold is the first standard deviation deviation threshold, and the rate of change threshold is the first rate of change threshold. For example: using the first time period threshold, such as 0.75s, as the segment length, the first pressure characteristic value is segmented and rearranged, and if the data deviation of the first pressure characteristic value after segmentation exceeds the first standard deviation deviation threshold, such as 1.5, the first pressure characteristic value corresponding to the segment is deleted. For example: if the change rate of two adjacent data in the first pressure characteristic value exceeds the first rate of change threshold, such as 100%, the corresponding first pressure characteristic value is deleted.

[0112] Optionally, if the first pressure characteristic value is one of the first symmetry value characteristic value, the first load-bearing value characteristic value, or the first pressure distribution value characteristic value, then the time period threshold for de-escalation value operation of the acquired first pressure characteristic value according to the standard deviation and the rate of change is the second time period threshold, the standard deviation deviation threshold is the second standard deviation deviation threshold, and the rate of change threshold is the second rate of change threshold. Optionally, the second time period threshold is less than the first time period threshold, optionally, the second standard deviation threshold is equal to the first standard deviation threshold, and optionally, the second rate of change threshold is less than the first rate of change threshold. For example, the second time period threshold, such as 0.5s, is used as the segment length, and the second pressure characteristic value is segmented and rearranged. If the data deviation of the second pressure characteristic value after segmentation exceeds the second standard deviation deviation threshold, such as 1.5, the second pressure characteristic value corresponding to the segment is deleted. For example, if the change rate of two adjacent data in the second pressure characteristic value exceeds the second rate of change threshold, such as 30%, the corresponding second pressure characteristic value is deleted.

Optionally, the second pressure feature set can correspond to the first pressure feature set described above, and the second pressure characteristic value can correspond to the first pressure characteristic value described above, that is, the second pressure characteristic value can be one of the second maximum characteristic value, or the second average characteristic value, or the second symmetric value characteristic value, or the second bearing value characteristic value, or the second pressure distribution value characteristic value. Among them, the second maximum characteristic value refers to the characteristic value corresponding to the maximum pressure value corresponding to the second pressure data; the second average characteristic value refers to the characteristic value corresponding to the average pressure value corresponding to the second pressure data; the second symmetric value characteristic value refers to the characteristic value corresponding to the second pressure data that characterizes whether the pressure is symmetrical; the second bearing value characteristic value refers to the characteristic value corresponding to the force range of the second pressure data; the second pressure distribution value characteristic value refers to the characteristic value corresponding to the second pressure data that characterizes the pressure distribution. Its calculation formula is also shown above and will not be repeated here.

[0114] Optionally, after obtaining the second pressure characteristic value, the obtained second pressure characteristic value may be subjected to a de-radicalization operation to improve the accuracy of the second pressure characteristic value. The process of performing a de-radicalization operation on the obtained second pressure characteristic value is not limited, and optionally, the process of performing a de-radicalization operation on the obtained first pressure characteristic value described above may be referred to, which will not be repeated here.

[0115] Wherein, if the first pressure feature set and the second pressure feature set are as shown above, the first pressure parameter includes at least one first sub-pressure parameter; wherein, the present invention does not limit the first sub-pressure parameter, and any parameter that can determine the fatigue state of the user's body part corresponding to the sub-region according to the first pressure feature value included in the first pressure feature set and the second pressure feature value included in the corresponding second pressure feature set can be used as the first sub-pressure parameter provided by the present invention. Optionally, it can be the change ratio of the value corresponding to the second pressure feature set compared to the value corresponding to the first pressure feature set. Specifically, the first sub-pressure parameter can be the change ratio of the value corresponding to the second maximum value feature value compared to the value corresponding to the first maximum value feature value, or the change ratio of the value corresponding to the second average value feature value compared to the value corresponding to the first average value feature value, or the change ratio of the value corresponding to the second symmetric value feature value compared to the value corresponding to the first symmetric value feature value, or the change ratio of the value corresponding to the second bearing value feature value compared to the value corresponding to the first bearing value feature value, or the change ratio of the value corresponding to the second pressure distribution value feature value compared to the value corresponding to the first pressure distribution value feature value.

[0116] The process of determining the first pressure parameter of a sub-area of ​​a vehicle seat provided in an embodiment of the present invention collects first pressure data borne by the sub-area in a first time period, and collects second pressure data borne by the sub-area in a second time period, and determines the first pressure parameter of the sub-area based on the first pressure data and the second pressure data, wherein the first pressure data collected in the first time period is used as a reference basis, and the first pressure parameter used to determine the fatigue state of the user's body part corresponding to the sub-area is determined based on the second data collected in the second time period, thereby improving the accuracy of the determined fatigue state of the user's body part and further improving the accuracy of the seat control.

[0117] In a possible embodiment, the first pressure parameter includes at least one first sub-pressure parameter. For the description of the first pressure parameter and the first sub-pressure parameter, reference may be made to the description in step S202 and will not be repeated here. Optionally, determining the fatigue state of the user's body part corresponding to the sub-area based on the first pressure parameter of the sub-area may include: if it is determined that at least one of the at least one first sub-pressure parameter included in the first pressure parameter exceeds a preset threshold, determining that the fatigue state of the user's body part corresponding to the sub-area is a fatigued state. Otherwise, determining that the fatigue state of the user's body part corresponding to the sub-area is a non-fatigued state.

[0118] Among them, in the process of determining the fatigue state of the user's body part corresponding to the sub-area according to the first pressure parameter of the sub-area, the preset threshold is the threshold corresponding to each first sub-pressure parameter, wherein the present invention does not limit the threshold corresponding to each first sub-pressure parameter. Optionally, if the first sub-pressure parameter is the change ratio of the numerical value corresponding to the second maximum value eigenvalue compared to the numerical value corresponding to the first maximum value eigenvalue, the corresponding preset threshold may be 12%; if the first sub-pressure parameter is the change ratio of the numerical value corresponding to the second average value eigenvalue compared to the numerical value corresponding to the first average value eigenvalue, the corresponding preset threshold may be 15%; if the first sub-pressure parameter is the change ratio of the numerical value corresponding to the second symmetric value eigenvalue compared to the numerical value corresponding to the first symmetric value eigenvalue, the corresponding preset threshold may be 25%; if the first sub-pressure parameter is the change ratio of the numerical value corresponding to the second bearing value eigenvalue compared to the numerical value corresponding to the first bearing value eigenvalue, the corresponding preset threshold may be 15%; if the first sub-pressure parameter is the change ratio of the numerical value corresponding to the second pressure distribution value eigenvalue compared to the numerical value corresponding to the first pressure distribution value eigenvalue, the corresponding preset threshold may be 20%. Optionally, if the first pressure characteristic value is also the first symmetric value characteristic value, and the corresponding second pressure characteristic value is the second symmetric value characteristic value, then the determined first sub-pressure parameter may be the value corresponding to the second symmetric value characteristic value, and the corresponding preset threshold may be 15%.

[0119] Among them, in the process of determining the fatigue state of the user's body part corresponding to the sub-area according to the first pressure parameter of the sub-area, each first sub-pressure parameter included in the first pressure parameter is determined according to a preset threshold, which improves the accuracy of determining the fatigue state of the user's body part corresponding to the sub-area and further improves the accuracy of seat control.

[0120] In a possible embodiment, if the fatigue state of the user's body part corresponding to the sub-region is in a fatigued state, then controlling the sub-region to move may include: if the fatigue state of the user's body part corresponding to the sub-region is in a fatigued state, and it is determined that the sub-region is a designated sub-region, then executing the step of controlling the sub-region to move.

[0121] The designated sub-region is a sub-region that has less impact on driving safety, for example, a region other than the leg region and / or the hip region.

[0122] Among them, by setting a designated sub-area that has less impact on driving safety, and if the fatigue state of the user's body part corresponding to the sub-area is in a fatigued state, then in the case of the designated sub-area, executing the step of controlling the sub-area to move can improve the safety of seat control.

[0123] In a possible embodiment, if the fatigue state of the user's body part corresponding to the sub-region is already fatigued, and it is determined that the sub-region is a designated sub-region, the step of controlling the sub-region to move may include: if the fatigue state of the user's body part corresponding to the sub-region is already fatigued, and it is determined that the sub-region is a designated sub-region, then determining the first motion parameter corresponding to the sub-region, and controlling the sub-region to move according to the first motion parameter. The first motion parameter is a parameter corresponding to the movement that relieves fatigue of the user's body part corresponding to the sub-region; if the user's body parts corresponding to the sub-region are different, the corresponding first motion parameters are also different. The present invention does not limit the process of determining the first motion parameter corresponding to the sub-region. Optionally, the first motion parameter corresponding to the sub-region can be determined according to a preset corresponding relationship. Among them, the present invention does not limit the type of the first motion parameter. Optionally, it can correspond to the type of at least one fatigue relief device preset in the seat. For example, if the fatigue relief device preset in the seat is a mechanical massage device, then the corresponding first motion parameter type is the mechanical motion parameter of the mechanical massage device. For example, if the fatigue relief device preset in the seat is an air pump massage device, then the corresponding first motion parameter type is the inflation / deflation motion parameter of the air pump massage device.

[0124] If it is determined that the sub-region is a designated sub-region, the sub-region is automatically controlled to move according to the first motion parameter, which can effectively improve the accuracy of seat control and user experience.

[0125] Optionally, if it is determined that the fatigue state of the user's body part corresponding to the sub-region is a fatigued state, and the duration of the fatigued state exceeds a preset time length threshold, such as 20 minutes, a prompt message that the user's body part corresponding to the sub-region is over-fatigue is generated and issued. Optionally, if after determining that the fatigue state of the user's body part corresponding to the sub-region is a fatigued state, a first motion parameter corresponding to the sub-region is determined, and the time for controlling the sub-region to exercise according to the first motion parameter exceeds a preset time length threshold, such as 20 minutes, then on the basis of generating and issuing a prompt message that the user's body part corresponding to the sub-region is over-fatigued, controlling the sub-region to exercise according to the first motion parameter is stopped.

[0126] Optionally, within a preset time length threshold, for example 30 minutes, after determining that the fatigue state of the user body part corresponding to the sub-area is a fatigued state, if the fatigue state of the user body part corresponding to the same sub-area is again determined to be a fatigued state, a prompt message indicating that the user body part corresponding to the sub-area is fatigued again in a short period of time is generated and issued, and the process of further determining the first motion parameter corresponding to the sub-area and controlling the sub-area to perform exercise according to the first motion parameter is stopped.

[0127] In a possible embodiment, the control method of the seat also includes: if it is determined that the sub-area is a non-designated sub-area, and the fatigue state of the user's body part corresponding to the sub-area is already in a fatigued state, a first prompt message is generated and issued. The first prompt message is a prompt message that reminds the user that the body part corresponding to the sub-area is already in a fatigued state. The present invention does not limit the first prompt message. Any prompt message that can remind the user that the body part corresponding to the sub-area is already in a fatigued state can be used as the first prompt message provided by the present invention. Optionally, it can be one or more of a text-type prompt message, a voice-type prompt message, and an animated prompt message. The first prompt message indicates the user's body part corresponding to the sub-area. For example: if it is determined that the sub-area is a leg, and the fatigue state of the user's body part corresponding to the sub-area is already in a fatigued state, the first prompt message generated and issued can be "The system detects that your legs are getting tired. If conditions permit, you can swing your legs."

[0128] Among them, if it is determined that the sub-area is a non-designated sub-area, the sub-area is not automatically controlled to move, but a first prompt message is generated and issued to prompt the user of the fatigue state of the corresponding body part, which can effectively improve the safety of seat control and user experience.

[0129] Optionally, if it is determined that the sub-area is a designated sub-area, and the fatigue state of the user's body part corresponding to the sub-area is already in a fatigued state, a first prompt message may also be generated and issued. For example: if it is determined that the sub-area is a shoulder, and the fatigue state of the user's body part corresponding to the sub-area is already in a fatigued state, the first prompt message generated and issued may be "The system detects that your shoulders are becoming fatigued. If conditions permit, you can swing your shoulders, and the system will also relieve your shoulder fatigue." Among them, if it is determined that the sub-area is a designated sub-area, whether to generate and issue the first prompt message, or the type of the first prompt message sent, can be preset according to user needs.

[0130] Optionally, if it is determined that the sub-region is a designated sub-region, and the fatigue state of the user's body part corresponding to the sub-region is already in a fatigued state, only the first prompt information may be generated and issued, that is, the process of controlling the sub-region to exercise is not executed. If it is determined that the sub-region is a designated sub-region, whether to execute the process of controlling the sub-region to exercise can be preset according to the needs of the user.

Figure 3 As shown, the method of the embodiment of the present invention includes:

[0132] Step S301: Before the vehicle travels, determine a second pressure parameter of a sub-region of the vehicle seat, and determine a posture matching state between the sub-region and a corresponding user body part according to the second pressure parameter of the sub-region.

[0133] Specifically, before the vehicle is driven, the second pressure parameter of the sub-region of the vehicle seat can be determined, and the posture matching state between the sub-region and the corresponding user body part can be determined according to the second pressure parameter of the sub-region. The description of the sub-region of the vehicle seat in the present invention can refer to the description in step S101, which will not be repeated here.

[0134] Wherein, the second pressure parameter is a pressure-related parameter used to determine the posture matching state between the sub-area and the corresponding user body part, wherein the present invention does not limit the second pressure parameter, and any pressure-related parameter that can be used to determine the posture matching state between the sub-area and the corresponding user body part can be used as the second pressure parameter provided by the present invention. Wherein, the present invention does not limit the process of determining the second pressure parameter of the sub-area of ​​the vehicle seat, wherein the process of determining the second pressure parameter of the sub-area of ​​the vehicle seat corresponds to the position pressure parameter provided by the present invention, and optionally, the third pressure data borne by the sub-area at the preset time can be collected first. Then, based on the third pressure data, the second pressure parameter of the sub-area is determined. Wherein, the preset time is the time before the vehicle starts to travel, after the user body part corresponding to each sub-area remains unchanged within the preset time length.

[0135] Wherein, the posture matching state between the sub-region and the corresponding user body part includes a matched state and an unmatched state; that is, the posture matching state between the sub-region and the corresponding user body part is that the posture matching state between the sub-region and the corresponding user body part is a matched state, or that the posture matching state between the sub-region and the corresponding user body part is an unmatched state. Wherein, the present invention does not limit the process of determining the posture matching state between the sub-region and the corresponding user body part according to the second pressure parameter of the sub-region, wherein the process of determining the posture matching state between the sub-region and the corresponding user body part according to the second pressure parameter of the sub-region corresponds to the second pressure parameter provided by the present invention. Optionally, if the second pressure parameter includes at least one second sub-pressure parameter; then determining the posture matching state between the sub-region and the corresponding user body part according to the second pressure parameter of the sub-region includes: if it is determined that at least one of the at least one second sub-pressure parameter included in the second pressure parameter exceeds a preset threshold, then determining that the posture matching state between the sub-region and the corresponding user body part is an unmatched state; otherwise, determining that the posture matching state between the sub-region and the corresponding user body part is a matched state.

[0136] Step S302: If the posture matching state between the sub-region and the corresponding user body part is not matched, the sub-region is controlled to move to adjust the seat posture of the sub-region.

[0137] Specifically, if the posture matching state between the sub-region and the corresponding part of the user's body is an unmatched state, the sub-region can be controlled to move to adjust the chair posture of the sub-region. Among them, the present invention does not limit the process of controlling the sub-region to move if the posture matching state between the sub-region and the corresponding part of the user's body is an unmatched state to adjust the chair posture of the sub-region. Optionally, if the posture matching state between the sub-region and the corresponding part of the user's body is an unmatched state, the second motion parameter corresponding to the sub-region is determined, and the sub-region is controlled to move according to the second motion parameter, and / or a second prompt information is generated and issued according to the second motion parameter; the second prompt information indicates that the chair posture of the sub-region is adjusted. If the posture matching state between the sub-region and the corresponding part of the user's body is a matched state, the sub-region is not controlled to move.

[0138] Step S303: during the driving of the vehicle, determine a first pressure parameter of a sub-region of the vehicle seat, and determine a fatigue state of a user's body part corresponding to the sub-region based on the first pressure parameter of the sub-region.

[0139] Specifically, for the detailed description of this step, reference may be made to the description of step S101, which will not be repeated here.

[0140] Step S304: If the fatigue state of the user's body part corresponding to the sub-region is already in a fatigued state, control the sub-region to move to relieve the fatigue of the user's body part corresponding to the sub-region.

[0141] Specifically, for the detailed description of this step, reference may be made to the description in step S102, which will not be repeated here.

[0142] The seat control method provided by the embodiment of the present invention comprises: Figure 1 On the basis of the shown embodiment, a second pressure parameter of a sub-area of ​​the vehicle seat is first determined, and based on the second pressure parameter of the sub-area, a posture matching state between the sub-area and the corresponding part of the user's body is determined; if the posture matching state between the sub-area and the corresponding part of the user's body is an unmatched state, the sub-area is controlled to move to adjust the seat posture of the sub-area, so that the user can adjust the seat posture before driving, thereby reducing the probability of user fatigue driving during vehicle driving, thereby improving the accuracy of seat control and user experience.

[0143] Figure 4 The process of the seat control method provided by one embodiment of the present invention is as follows Figure 4 .exist Figure 1 or Figure 2 or Figure 3 Based on the embodiment shown in FIG. 1 , this embodiment further describes the process of determining the second pressure parameter of the sub-region of the vehicle seat. Figure 4 As shown, the method of the embodiment of the present invention includes:

[0144] Step S401: collecting third pressure data borne by the sub-area at a preset time.

[0145] Specifically, the third pressure data of the sub-area at the preset time can be collected. The preset time is the time before the vehicle starts to travel, after the user's body parts corresponding to each sub-area remain unchanged within the preset time. The present invention does not limit the preset time corresponding to the process of collecting the third pressure data, and can be 3 seconds. For the description of the sub-area and the description of the user's body parts corresponding to each sub-area, reference can be made to the description in step S101. Optionally, if the vehicle seat to be controlled can include five sub-areas of the vehicle seat, for example, it can include a sub-area corresponding to the shoulder, a sub-area corresponding to the back, a sub-area corresponding to the waist, a sub-area corresponding to the buttocks, and a sub-area corresponding to the leg, the preset time is the time before the vehicle starts to travel, after the user's body parts corresponding to each sub-area, that is, the sub-area corresponding to the shoulder, the sub-area corresponding to the back, the sub-area corresponding to the waist, the sub-area corresponding to the buttocks, and the sub-area corresponding to the leg remain unchanged.

[0146] The third pressure data is data representing the pressure borne by the sub-region at the preset moment, wherein the present invention does not limit the third pressure data, and any data that can represent the pressure borne by the sub-region at the preset moment can be used as the third pressure data provided by the present invention. Optionally, the third pressure data can refer to the first pressure data and the second pressure data described in step S201, and can be the pressure values ​​corresponding to multiple pressure points in the sub-region at the preset moment.

[0147] Step S402: Determine a second pressure parameter of the sub-region according to the third pressure data.

[0148] Specifically, according to the third pressure data collected in step S401, the second pressure parameter of the sub-area can be determined. For the description of the second pressure parameter, reference can be made to the description in step S301, which will not be repeated here.

[0149] The present invention does not limit the process of determining the second pressure parameter of the sub-region according to the third pressure data. Optionally, the third pressure feature set of the sub-region may be determined according to the third pressure data. The second pressure parameter of the sub-region is then determined according to the third pressure feature set of the sub-region and the third pressure feature sets of other sub-regions.

[0150] Among them, in the process of determining the second pressure parameter of the sub-area based on the third pressure data, the third pressure feature set of the sub-area is first determined, and the pressure characteristics of the third pressure data can be extracted to improve the accuracy of determining the second pressure parameter. In the process, the third pressure feature sets of other sub-areas are combined to further improve the accuracy of determining the second pressure parameter, thereby improving the accuracy of seat control.

[0151] Among them, the present invention does not limit the third pressure feature set. Any pressure feature that can characterize the third pressure data and can determine the second pressure parameter of the sub-area can be used as the third pressure feature set provided by the present invention. Correspondingly, the present invention does not limit the third pressure characteristic value included in the third pressure feature set. Optionally, the third pressure characteristic value can be one of the third maximum value sub-characteristic value, the third average value sub-characteristic value, the third symmetry value sub-characteristic value, or the third bearing value sub-characteristic value.

[0152] Optionally, the second pressure parameter includes at least one second sub-pressure parameter. The second sub-pressure parameter is one of a maximum sub-pressure parameter, an average sub-pressure parameter, a symmetric sub-pressure parameter, or a load-bearing ratio sub-pressure parameter. The process of determining the second pressure parameter of the sub-area based on the third pressure feature set of the sub-area and the third pressure feature set of other sub-areas may include: if the second sub-pressure parameter is a symmetric sub-pressure parameter, then the symmetric sub-pressure parameter included in the second pressure parameter is determined based on the third pressure feature set of the sub-area. If the second sub-pressure parameter is one of a maximum sub-pressure parameter, an average sub-pressure parameter, a symmetric sub-pressure parameter, or a load-bearing ratio sub-pressure parameter, then the corresponding second sub-pressure parameter included in the second pressure parameter is determined based on the third pressure feature set of the sub-area and the third pressure feature set of other sub-areas.

[0153] In the process of determining the second pressure parameter, different determination processes are determined according to the characteristics of different second sub-pressure parameters, which can improve the accuracy of determining each second sub-pressure parameter, thereby improving the accuracy of seat control.

[0154] Among them, if the second sub-pressure parameter is a symmetric value sub-pressure parameter, then the process of determining the symmetric value sub-pressure parameter included in the second pressure parameter based on the third pressure feature set of the sub-area may include: determining the numerical value corresponding to the third symmetric value sub-feature value included in the third pressure feature set of the sub-area as the symmetric value sub-pressure parameter included in the second pressure parameter.

[0155] Among them, if the second sub-pressure parameter is one of the maximum value sub-pressure parameter, the average value sub-pressure parameter, the symmetry value sub-pressure parameter, or the load-bearing ratio value sub-pressure parameter, then according to the third pressure feature set of the sub-area and the third pressure feature sets of other sub-areas, the process of determining the corresponding second sub-pressure parameter included in the second pressure parameter may include: determining the ratio of the corresponding third pressure characteristic value in the third pressure feature set of the sub-area to the corresponding third pressure characteristic value in the third pressure feature set of other sub-areas, and determining the ratio as the corresponding second sub-pressure parameter included in the second pressure parameter.

[0156] The process of determining the second pressure parameter of a sub-area of ​​a vehicle seat provided in an embodiment of the present invention collects third pressure data that the sub-area is borne at a preset moment, and determines the second pressure parameter of the sub-area based on the third pressure data. In the process of determining the second pressure parameter of the sub-area, the accuracy of the second pressure parameter can be improved by determining the third pressure data borne by each sub-area, thereby further improving the accuracy of seat control.

[0157] In a possible embodiment, the second pressure parameter may include at least one second sub-pressure parameter. The process of determining the posture matching state between the sub-region and the corresponding user body part according to the second pressure parameter of the sub-region may include: if it is determined that at least one of the at least one second sub-pressure parameter included in the second pressure parameter exceeds a preset threshold, then determining that the posture matching state between the sub-region and the corresponding user body part is an unmatched state. Otherwise, determining that the posture matching state between the sub-region and the corresponding user body part is a matched state.

[0158] Among them, when the corresponding second sub-pressure parameter is different, the corresponding preset threshold is different, for example: if the corresponding second sub-pressure parameter is a symmetrical value sub-pressure parameter, the corresponding preset threshold is 12%; for example: if the corresponding second sub-pressure parameter is not a symmetrical value sub-pressure parameter, the corresponding preset threshold is the difference ratio with the preset ratio, optionally, it can be 15%. Among them, the preset ratio is the ratio of the third pressure characteristic value of the preset sub-area to other sub-areas, for example: if the third pressure characteristic value is the third maximum characteristic value, and the sub-area is the waist, and the other sub-areas are the buttocks, back, shoulders, and legs, respectively, then the preset ratio can be 1:2, 1:0.5, 1:0.3, 1:0.7, respectively; for example: if the third pressure characteristic value is the third average characteristic value, and the sub-area is the waist, and the other sub-areas are the buttocks, back, shoulders, and legs, respectively, then the preset ratio can be 1:1.9, 1:0.4, 1:0.3, 1:0.8, respectively; for example: if the third pressure characteristic value is the third load-bearing value characteristic value, and the sub-area is the waist, and the other sub-areas are the buttocks, back, shoulders, and legs, respectively, then the preset ratio can be 4:6:9:3:10.

[0159] Among them, each second sub-pressure parameter included in the second pressure parameter is determined according to a preset threshold value, which improves the accuracy of determining the posture matching state of the user's body part corresponding to the sub-area, and further improves the accuracy of seat control.

[0160] In a possible embodiment, controlling the sub-region to move according to the posture matching state between the sub-region and the corresponding user body part may include: if the posture matching state between the sub-region and the corresponding user body part is an unmatched state, determining the second motion parameter corresponding to the sub-region, and controlling the sub-region to move according to the second motion parameter, and / or generating and issuing a second prompt message according to the second motion parameter.
