[0074] In the prior art, the driving fatigue of the user can be relieved by adjusting the sitting posture of the vehicle seat at regular intervals. However, the method in the prior art causes inaccurate control and poor user experience.

[0075] The present application determines the first pressure parameter of the sub-area of the vehicle seat during the driving of the vehicle, and determines the fatigue state of the user body part corresponding to the sub-area according to the first pressure parameter of the sub-area. If the fatigue state of the user body part corresponding to the sub-area is the fatigued state, the sub-area is controlled to move to relieve the fatigue of the user body part corresponding to the sub-area. In the control process of the seat, the fatigue state of the user body part corresponding to the sub-area is determined first, which can more accurately determine the fatigue state of the user body. Further, if the fatigue state of the user body part corresponding to the sub-area is the fatigued state, the sub-area is controlled to move to relieve the fatigue of the user body part corresponding to the sub-area, which can more accurately and efficiently relieve the fatigue of the specific part of the user body, thereby improving the accuracy of the control of the seat and the user experience.

[0076] The technical solutions of the present application will be 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 can not be described in detail in some embodiments.

[0077] Figure 1 The flow of the control method of the seat provided by an embodiment of the present application Figure 1 As shown in Figure 1 , the method of the embodiment of the present application comprises:

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

[0079] Specifically, during vehicle driving, the first pressure parameter of each sub-region of the vehicle seat can be determined, and the fatigue state of the body part of the user corresponding to each sub-region can be determined according to the first pressure parameter of the sub-region. The sub-region of the vehicle seat refers to a sub-region corresponding to different body parts of the user in the vehicle seat. The present application does not limit the sub-region of the vehicle seat, and any sub-region corresponding to different body parts of the user in the vehicle seat can be used as the sub-region of the vehicle seat provided by the present application. Optionally, the vehicle seat to be controlled can include five sub-regions of vehicle seats, for example, a sub-region corresponding to the shoulder, a sub-region corresponding to the back, a sub-region corresponding to the waist, a sub-region corresponding to the hips, and a sub-region corresponding to the legs.

[0080] The first pressure parameter is a pressure-related parameter used to determine the fatigue state of the body part of the user corresponding to the sub-region. The present application does not limit the first pressure parameter, and any pressure-related parameter that can be used to determine the fatigue state of the body part of the user corresponding to the sub-region can be used as the first pressure parameter provided by the present application. The present application does not limit the process of determining the first pressure parameter of the sub-region of the vehicle seat, and the process of determining the first pressure parameter of the sub-region of the vehicle seat corresponds to the first pressure parameter provided by the present application. Optionally, first pressure data borne by the sub-region in a first time period can be collected, and second pressure data borne by the sub-region in a second time period can be collected; then the first pressure parameter of the sub-region can be determined according to the first pressure data and the second pressure data. The first time period is a time period after the vehicle starts driving and after the vehicle speed is greater than a preset threshold for a preset duration. The second time period is a time period after the first time period.

[0081] The fatigue state of the user body part corresponding to the sub-region includes a fatigued state and a non-fatigued state. That is, the fatigue state of the user body part corresponding to the sub-region is a fatigued state, or the fatigue state of the user body part corresponding to the sub-region is a non-fatigued state. The process of determining the fatigue state of the user body part corresponding to the sub-region according to the first pressure parameter of the sub-region is not limited in the application, and the process of determining the fatigue state of the user 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 application. Optionally, if the first pressure parameter includes at least one first sub-pressure parameter, the process of determining the fatigue state of the user body part corresponding to the sub-region according to the first pressure parameter of the sub-region can 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, it is determined that the fatigue state of the user body part corresponding to the sub-region is a fatigued state; otherwise, it is determined that the fatigue state of the user body part corresponding to the sub-region is a non-fatigued state.

[0082] In step S102, if the fatigue state of the user body part corresponding to the sub-region is a fatigued state, the motion of the sub-region is controlled to relieve fatigue of the user body part corresponding to the sub-region.

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

[0084] The process of controlling the motion of the sub-region to relieve fatigue of the user body part corresponding to the sub-region if the fatigue state of the user body part corresponding to the sub-region is a fatigued state is not limited in the application, and any process of controlling the motion of the sub-region to relieve fatigue of the user body part corresponding to the sub-region if the fatigue state of the user body part corresponding to the sub-region is a fatigued state can be used as the process of controlling the motion of the sub-region to relieve fatigue of the user body part corresponding to the sub-region if the fatigue state of the user body part corresponding to the sub-region is a fatigued state provided by the application. Optionally, if the fatigue state of the user body part corresponding to the sub-region is a fatigued state, it can be determined whether the sub-region is a designated sub-region, and if it is determined that the sub-region is a designated sub-region, the step of controlling the motion of the sub-region is performed.

[0085] The control method of the seat provided by the embodiment of the present application can determine the first pressure parameter of the sub-region of the seat of the vehicle during the driving of the vehicle, determine the fatigue state of the body part of the user corresponding to the sub-region according to the first pressure parameter of the sub-region, and control the sub-region to move to relieve the fatigue of the body part of the user corresponding to the sub-region if the fatigue state of the body part of the user corresponding to the sub-region is the fatigued state. During the control of the seat, the fatigue state of the body part of the user corresponding to the sub-region is determined first, so that the fatigue state of the user's body can be determined more accurately. If the fatigue state of the body part of the user corresponding to the sub-region is the fatigued state, the sub-region is controlled to move to relieve the fatigue of the body part of the user corresponding to the sub-region, so that the fatigue state of the specific body part of the user can be relieved more accurately and efficiently, thereby improving the accuracy of the control of the seat and the user experience.

[0086] Figure 2 The control method of the seat provided by the embodiment of the present application can determine the first pressure parameter of the sub-region of the seat of the vehicle during the driving of the vehicle, determine the fatigue state of the body part of the user corresponding to the sub-region according to the first pressure parameter of the sub-region, and control the sub-region to move to relieve the fatigue of the body part of the user corresponding to the sub-region if the fatigue state of the body part of the user corresponding to the sub-region is the fatigued state. During the control of the seat, the fatigue state of the body part of the user corresponding to the sub-region is determined first, so that the fatigue state of the user's body can be determined more accurately. If the fatigue state of the body part of the user corresponding to the sub-region is the fatigued state, the sub-region is controlled to move to relieve the fatigue of the body part of the user corresponding to the sub-region, so that the fatigue state of the specific body part of the user can be relieved more accurately and efficiently, thereby improving the accuracy of the control of the seat and the user experience. Figure 1 . In Figure 2 On the basis of the embodiment shown in the figure, the embodiment further describes the process of determining the first pressure parameter of the sub-region of the seat of the vehicle, as shown in the figure. Figure 3 The method of the embodiment of the present application comprises the following steps:

[0087] In step S201, the first pressure data borne by the sub-region in the first time period is collected, and the second pressure data borne by the sub-region in the second time period is collected.

[0088] Specifically, the first pressure data borne by the sub-region in the first time period can be collected. The first time period is the time period after the vehicle starts driving and after the vehicle speed is greater than a preset threshold value in a preset time period. The present application does not limit the preset time period in the process of collecting the first pressure data, which can be one minute. The present application does not limit the preset threshold value of the vehicle speed in the process of collecting the first pressure data, which can be 20 km / 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 in which the seat to be controlled is in the driving state for a certain time, that is, the vehicle in which the seat to be controlled has been stably in the driving state. The present application does not limit the time period of the first time period, which can be 5 minutes.

[0089] The first pressure data is data representing the pressure borne by the sub-region in the first time period. The application does not limit the first pressure data. Any data representing the pressure borne by the sub-region in the first time period can be used as the first pressure data provided by the application. Optionally, if the sub-region of the vehicle seat is described as shown in step S101, the first pressure data can be the pressure values corresponding to the plurality of pressure points in the sub-region in the first time period. The application does not limit the number of pressure points included in each sub-region. Optionally, the number of pressure points included in the sub-region corresponds to the body part of the user corresponding to the sub-region. If the body part of the user corresponding to the sub-region has a larger area, the number of pressure points corresponding to the sub-region is larger. Conversely, if the body part of the user corresponding to the sub-region has a smaller area, the number of pressure points corresponding to the sub-region is smaller.

[0090] The second time period is a time period after the first time period. The application does not limit the second time period. Any time period after the first time period can be used as the second time period provided by the application. The second time period can be a time period after a preset time period after the first time period. The application does not limit the preset time period corresponding to the collection of the second pressure data. Optionally, the preset time period can be 30 minutes. During the collection of the second pressure data, the purpose of setting the preset time period is to determine that the user does not have driving fatigue within the preset time period after the first time period, so that the second pressure data and the first pressure parameter of the sub-region do not need to be collected. The application does not limit the length of the time period corresponding to the second time period. Optionally, the length of the time period corresponding to the second time period can be equal to the length of the time period corresponding to the first time period. For example, if the length of the time period corresponding to the first time period is five minutes, the length of the time period corresponding to the second time period is also five minutes. Optionally, the length of the time period corresponding to the second time period can not be equal to the length of the time period corresponding to the first time period. For example, if the length of the time period corresponding to the first time period is five minutes, the length of the time period corresponding to the second time period can be six minutes.

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

[0092] Step S202, determining the first pressure parameter of the sub-region according to the first pressure data and the second pressure data.

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

[0094] In the process of determining the first pressure parameter of the sub-region according to the first pressure data and the second pressure data, at least one pressure characteristic value corresponding to each pressure data is determined respectively, which can more accurately extract the characteristics of the first pressure data and the second pressure data, and then the first pressure parameter of the sub-region is determined according to 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.

[0095] In the process of determining the first pressure parameter of the sub-region according to the first pressure data and the second pressure data, at least one pressure characteristic value corresponding to each pressure data is determined respectively, which can more accurately extract the characteristics of the first pressure data and the second pressure data, and then the first pressure parameter of the sub-region is determined according to 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] In the process of determining the first pressure parameter of the sub-region according to the first pressure data and the second pressure data, at least one pressure characteristic value corresponding to each pressure data is determined respectively, which can more accurately extract the characteristics of the first pressure data and the second pressure data, and then the first pressure parameter of the sub-region is determined according to 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.

Alternatively, the change ratio of the value corresponding to the second pressure characteristic set to the value corresponding to the first pressure characteristic set can be used as the first sub-pressure parameter. Specifically, the first sub-pressure parameter can be the change ratio of the value corresponding to the second maximum value feature to the value corresponding to the first maximum value feature, or the change ratio of the value corresponding to the second average value feature to the value corresponding to the first average value feature, or the change ratio of the value corresponding to the second symmetry value feature to the value corresponding to the first symmetry value feature, or the change ratio of the value corresponding to the second force value feature to the value corresponding to the first force value feature, or the change ratio of the value corresponding to the second pressure distribution value feature to the value corresponding to the first pressure distribution value feature.

[0116] The process for determining the first pressure parameter of the sub-region of the vehicle seat provided by the embodiments of the application can improve the accuracy of the fatigue state of the user's body part by collecting the first pressure data of the sub-region in the first time period, collecting the second pressure data of the sub-region in the second time period, and determining the first pressure parameter of the sub-region according to the first pressure data and the second pressure data, and further improving the accuracy of the control of the seat.

[0117] In a possible embodiment, at least one first sub-pressure parameter is included in the first pressure parameter. The description of the first pressure parameter and the first sub-pressure parameter can refer to the description in step S202, which will not be repeated here. Alternatively, 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 can include: if at least one of the at least one first sub-pressure parameter included in the first pressure parameter exceeds the preset threshold value, determining that the fatigue state of the user's body part corresponding to the sub-region is the fatigued state. Otherwise, it is determined that the fatigue state of the user's body part corresponding to the sub-region is the non-fatigued state.

[0118] In the process of determining the fatigue state of the user body part corresponding to the sub-region according to the first pressure parameter of the sub-region, the preset threshold is a threshold corresponding to each first sub-pressure parameter, and the application does not limit the threshold corresponding to each first sub-pressure parameter.

Optionally, if the first pressure characteristic value is also the first symmetry characteristic value, and the corresponding second pressure characteristic value is the second symmetry characteristic value, the determined first sub-pressure parameter can be the value corresponding to the second symmetry characteristic value, and the corresponding preset threshold can be 15%.

[0119] In the process of determining the fatigue state of the user body part corresponding to the sub-region according to the first pressure parameter of the sub-region, each first sub-pressure parameter included in the first pressure parameter is determined according to the preset threshold, which improves the accuracy of determining the fatigue state of the user body part corresponding to the sub-region and further improves the accuracy of controlling the seat.

[0120] In a possible embodiment, if the fatigue state of the user body part corresponding to the sub-region is the fatigued state, the step of controlling the sub-region to move can include: if the fatigue state of the user body part corresponding to the sub-region is the fatigued state and it is determined that the sub-region is a specified sub-region, the step of controlling the sub-region to move is performed.

[0121] The specified 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] By setting the specified sub-region that has less impact on driving safety, and if the fatigue state of the user body part corresponding to the sub-region is the fatigued state, the step of controlling the sub-region to move is performed when the sub-region is the specified sub-region, which can improve the safety of the seat control.

[0123] In a possible implementation, if the fatigue state of the body part corresponding to the sub-region is the fatigued state and it is determined that the sub-region is the specified sub-region, the step of controlling the sub-region to move can include: if the fatigue state of the body part corresponding to the sub-region is the fatigued state and it is determined that the sub-region is the specified sub-region, determining a first movement parameter corresponding to the sub-region, and controlling the sub-region to move according to the first movement parameter. The first movement parameter is a parameter corresponding to a movement that relieves fatigue of the body part corresponding to the sub-region. If the body part corresponding to the sub-region is different, the corresponding first movement parameter is also different. The application does not limit the process of determining the first movement parameter corresponding to the sub-region. Optionally, the first movement parameter corresponding to the sub-region can be determined according to a preset correspondence. The application does not limit the type of the first movement parameter. Optionally, the type of the first movement parameter can correspond to the type of at least one fatigue-relieving device preset in the seat. For example, if the fatigue-relieving device preset in the seat is a mechanical massage device, the type of the corresponding first movement parameter is a mechanical movement parameter of the mechanical massage device. For example, if the fatigue-relieving device preset in the seat is an air pump massage device, the type of the corresponding first movement parameter is a charging / discharging movement parameter of the air pump massage device.

[0124] If it is determined that the sub-region is the specified sub-region and the sub-region is automatically controlled to move according to the first movement parameter, the accuracy of the seat control and the user experience can be effectively improved.

[0125] Optionally, if it is determined that the fatigue state of the body part corresponding to the sub-region is the fatigued state and the time of the fatigued state lasts more than a preset time length threshold, for example, 20 minutes, a prompt information that the body part corresponding to the sub-region is over-fatigued is generated and sent. Optionally, if the first movement parameter corresponding to the sub-region is determined after it is determined that the fatigue state of the body part corresponding to the sub-region is the fatigued state, and the time of controlling the sub-region to move according to the first movement parameter exceeds a preset time length threshold, for example, 20 minutes, the process of controlling the sub-region to move according to the first movement parameter is stopped on the basis of generating and sending the prompt information that the body part corresponding to the sub-region is over-fatigued.

[0126] Optionally, within a preset time length threshold, for example, 30 minutes, after it is determined that the fatigue state of the body part corresponding to the sub-region is the fatigued state, if it is determined again that the fatigue state of the body part corresponding to the same sub-region is the fatigued state, a prompt information that the body part corresponding to the sub-region is fatigued again in a short time is generated and sent, and the process of determining the first movement parameter corresponding to the sub-region and controlling the sub-region to move according to the first movement parameter is stopped.

[0127] In a possible embodiment, the control method of the seat further includes: if it is determined that the sub-region is a non-designated sub-region and the fatigue state of the body part of the user corresponding to the sub-region is the fatigued state, generating and sending first prompt information. The first prompt information is prompt information for reminding that the body part of the user corresponding to the sub-region is in the fatigued state. The first prompt information is not limited in the present application, and any prompt information capable of reminding that the body part of the user corresponding to the sub-region is in the fatigued state can be used as the first prompt information provided by the present application. Optionally, the first prompt information can be one or more of a text type, a voice type and a dynamic effect type. The first prompt information indicates the body part of the user corresponding to the sub-region. For example, if it is determined that the sub-region is a leg and the fatigue state of the body part of the user corresponding to the sub-region is the fatigued state, the generated and sent first prompt information can be “The system detects that your leg is generating fatigue. If the condition allows, you can swing your leg”.

[0128] If it is determined that the sub-region is a non-designated sub-region, the sub-region is not automatically controlled to move, and the first prompt information is generated and sent to prompt the fatigue state of the body part of the user, which can effectively improve the safety of the seat control and the user experience.

[0129] Optionally, if it is determined that the sub-region is a designated sub-region and the fatigue state of the body part of the user corresponding to the sub-region is the fatigued state, the first prompt information can also be generated and sent. For example, if it is determined that the sub-region is a shoulder and the fatigue state of the body part of the user corresponding to the sub-region is the fatigued state, the generated and sent first prompt information can be “The system detects that your shoulder is generating fatigue. If the condition allows, you can swing your shoulder”, or “The system detects that your shoulder is generating fatigue. If the condition allows, you can swing your shoulder, and the system will also relieve the fatigue of your shoulder”. If it is determined that the sub-region is a designated sub-region, whether the first prompt information is generated and sent or the type of the sent first prompt information can be preset according to the needs of the user.

[0130] Optionally, if it is determined that the sub-region is a designated sub-region and the fatigue state of the body part of the user corresponding to the sub-region is the fatigued state, the first prompt information can also be generated and sent, that is, the process of controlling the sub-region to move is not performed. If it is determined that the sub-region is a designated sub-region, whether the process of controlling the sub-region to move is performed can be preset according to the needs of the user.

[0132] In step S301, before the vehicle driving process, the second pressure parameter of the sub-area of the vehicle seat is determined, and the pose matching state of the sub-area and the corresponding user body part is determined according to the second pressure parameter of the sub-area.

[0133] Specifically, before the vehicle driving process, the second pressure parameter of the sub-area of the vehicle seat can be determined, and the pose matching state of the sub-area and the corresponding user body part is determined according to the second pressure parameter of the sub-area. Wherein, the description of the sub-area of the vehicle seat in the present application 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 for determining the pose matching state of the sub-area and the corresponding user body part, wherein the present application does not limit the second pressure parameter, any pressure-related parameter that can be used to determine the pose matching state of the sub-area and the corresponding user body part can be used as the second pressure parameter provided by the present application. Wherein, the process of determining the second pressure parameter of the sub-area of the vehicle seat is not limited by the present application, 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 application, which can be optionally collected third pressure data borne by the sub-area at a preset time. Then, according to the third pressure data, the second pressure parameter of the sub-area is determined. Wherein, the preset time is the time after the user body part corresponding to each sub-area remains unchanged within a preset time length before the vehicle starts driving.

[0135] The pose matching state of the sub-region and the corresponding user body part includes a matched state and an unmatched state, that is, the pose matching state of the sub-region and the corresponding user body part is a matched state, or the pose matching state of the sub-region and the corresponding user body part is an unmatched state. The process of determining the pose matching state of the sub-region and the corresponding user body part according to the second pressure parameter of the sub-region is not limited, and the process of determining the pose matching state of 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 application. Optionally, if the second pressure parameter includes at least one second sub-pressure parameter, then determining the pose matching state of 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 the pose matching state of the sub-region and the corresponding user body part is determined to be an unmatched state; otherwise, the pose matching state of the sub-region and the corresponding user body part is determined to be a matched state.

[0136] In step S302, if the pose matching state of the sub-region and the corresponding user body part is an unmatched state, the sub-region is controlled to move to adjust the seat pose of the sub-region.

[0137] Specifically, if the pose matching state of the sub-region and the corresponding user body part is an unmatched state, the sub-region can be controlled to move to adjust the seat pose of the sub-region. The process of controlling the sub-region to move to adjust the seat pose of the sub-region if the pose matching state of the sub-region and the corresponding user body part is an unmatched state is not limited, and optionally, if the pose matching state of the sub-region and the corresponding user body part is an unmatched state, a 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 sent according to the second motion parameter; the second prompt information indicates that the seat pose of the sub-region is adjusted. If the pose matching state of the sub-region and the corresponding user body part is a matched state, the sub-region is not controlled to move.

[0138] In step S303, during vehicle driving, a first pressure parameter of a sub-region of a vehicle seat is determined, and a fatigue state of a user body part corresponding to the sub-region is determined according to the first pressure parameter of the sub-region.

[0139] Specifically, the specific description of this step can refer to the description in step S101, which will not be repeated here.

[0141] Specifically, the specific description of the present step can refer to the description in step S102, which will not be repeated here.

[0142] The control method of the seat provided by the embodiment of the present application has the advantages that Figure 4 On the basis of the embodiment shown, the second pressure parameter of the sub-region of the vehicle seat is determined first, and the pose matching state of the sub-region and the corresponding user body part is determined according to the second pressure parameter of the sub-region. If the pose matching state of the sub-region and the corresponding user body part is the unmatched state, the sub-region is controlled to move to adjust the seat pose, so that the user adjusts the seat pose before driving, thereby reducing the probability of fatigue driving of the user during the driving of the vehicle, and improving the accuracy of the seat control and the user experience.

[0143] Figure 4 The flowchart of the control method of the seat provided by an embodiment of the present application Figure 1 In Figure 2 or Figure 3 or Figure 4 On the basis of the embodiment shown, the process of determining the second pressure parameter of the sub-region of the vehicle seat is described in the present embodiment, as shown in Figure 5 The method of the embodiment of the present application includes:

[0144] Step S401, collect third pressure data borne by the sub-region at a preset time.

[0145] Specifically, the third pressure data borne by the sub-region at a preset time can be collected. The preset time is a time after the user body part corresponding to each sub-region remains unchanged within a preset time length before the vehicle starts driving. The present application does not limit the preset time length in the process of collecting the third pressure data, which can be 3 seconds. The description of the sub-region and the user body part corresponding to each sub-region can refer to the description in step S101. If the vehicle seat to be controlled can include five sub-regions of vehicle seats, for example, it can include a sub-region corresponding to the shoulder, a sub-region corresponding to the back, a sub-region corresponding to the waist, a sub-region corresponding to the hips, and a sub-region corresponding to the legs, the preset time is a time after the user body part corresponding to each of the sub-regions, i.e., the sub-region corresponding to the shoulder, the sub-region corresponding to the back, the sub-region corresponding to the waist, the sub-region corresponding to the hips, and the sub-region corresponding to the legs, remains unchanged within a preset time length before the vehicle starts driving.

[0146] The third pressure data is data representing the pressure borne by the sub-region at the preset moment. The third pressure data is not limited by the present application. Any data representing the pressure borne by the sub-region at the preset moment can be used as the third pressure data provided by the present application. 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 the plurality of pressure points in the sub-region at the preset moment.

[0147] In step S402, the second pressure parameter of the sub-region is determined according to the third pressure data.

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

[0149] The process of determining the second pressure parameter of the sub-region according to the third pressure data is not limited by the present application. Optionally, the third pressure feature set of the sub-region can be determined according to the third pressure data first. Then, the second pressure parameter of the sub-region can be determined according to the third pressure feature set of the sub-region and the third pressure feature set of other sub-regions.

[0150] In the process of determining the second pressure parameter of the sub-region according to the third pressure data, the third pressure feature set of the sub-region is determined first. The pressure features of the third pressure data can be extracted, which improves the accuracy of determining the second pressure parameter. In addition, the third pressure feature set of other sub-regions is combined in the process, which further improves the accuracy of determining the second pressure parameter, thereby improving the accuracy of controlling the seat.

[0151] The third pressure feature set is not limited by the present application. Any pressure feature representing the third pressure data and capable of determining the second pressure parameter of the sub-region can be used as the third pressure feature set provided by the present application. Correspondingly, the third pressure feature values included in the third pressure feature set are also not limited by the present application. Optionally, the third pressure feature value can be one of the third maximum sub-feature value, the third average sub-feature value, the third symmetry sub-feature value, and the third bearing sub-feature value.

[0152] Optionally, the second pressure parameter comprises at least one second sub-pressure parameter.

[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 controlling the seat.

[0154] If the second sub-pressure parameter is the symmetric value sub-pressure parameter, the process of determining the symmetric value sub-pressure parameter included in the second pressure parameter according to the third pressure feature set of the sub-region can comprise: determining the value corresponding to the third symmetric value sub-feature value included in the third pressure feature set of the sub-region as the symmetric value sub-pressure parameter included in the second pressure parameter.

[0155] If the second sub-pressure parameter is one of the maximum value sub-pressure parameter, the average value sub-pressure parameter, the symmetric value sub-pressure parameter, or the force bearing ratio value sub-pressure parameter, the process of determining the corresponding second sub-pressure parameter included in the second pressure parameter according to the third pressure feature set of the sub-region and the third pressure feature set of other sub-regions can comprise: determining the ratio of the corresponding third pressure feature value in the third pressure feature set of the sub-region to the corresponding third pressure feature value in the third pressure feature set of other sub-regions, 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 the sub-region of the vehicle seat provided by the embodiments of the present application can improve the accuracy of the second pressure parameter by collecting the third pressure data borne by the sub-region at a preset time and determining the second pressure parameter of the sub-region according to the third pressure data, and further improve the accuracy of controlling the seat.

[0157] In a possible embodiment, the second pressure parameter can include at least one second sub-pressure parameter. According to the second pressure parameter of the sub-region, the process of determining the pose matching state of the sub-region and the corresponding user body part can 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 the preset threshold value, it is determined that the pose matching state of the sub-region and the corresponding user body part is the unmatched state. Otherwise, it is determined that the pose matching state of the sub-region and the corresponding user body part is the matched state.

[0158] wherein the corresponding second sub-pressure parameter is different, the corresponding preset threshold value is different, for example: if the corresponding second sub-pressure parameter is a symmetric value sub-pressure parameter, the corresponding preset threshold value is 12%, for example: if the corresponding second sub-pressure parameter is not a symmetric value sub-pressure parameter, the corresponding preset threshold value is the difference ratio of the preset ratio, which can be 15%. Wherein the preset ratio is the preset ratio of the third pressure characteristic value of the sub-region to the third pressure characteristic value of other sub-regions, for example: if the third pressure characteristic value is the third maximum value characteristic value, and the sub-region is the waist, and the other sub-regions are the hips, the back, the shoulders and the legs, respectively, 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 value characteristic value, and the sub-region is the waist, and the other sub-regions are the hips, the back, the shoulders and the legs, respectively, 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 bearing value characteristic value, and the sub-region is the waist, and the other sub-regions are the hips, the back, the shoulders and the legs, respectively, the preset ratio can be 4:6:9:3:10.

[0159] wherein according to the preset threshold value, each second sub-pressure parameter included in the second pressure parameter is determined, which improves the accuracy of determining the pose matching state of the sub-region corresponding to the user body part, and further improves the accuracy of controlling the seat.

[0160] In a possible embodiment, according to the pose matching state of the sub-region and the corresponding user body part, the sub-region can be controlled to move, which can include: if the pose matching state of the sub-region and the corresponding user body part is the unmatched state, a 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 sent according to the second motion parameter. The second prompt information indicates the seat pose adjustment of the sub-region. Wherein the present application does not limit the second prompt information, any prompt information that can indicate the seat pose adjustment of the sub-region can be used as the second prompt information provided by the present application, which can be one or more of the text type prompt information, the voice type prompt information and the dynamic effect type prompt information.

[0161] In particular, determining the second motion parameter corresponding to the sub-region during the movement of the control sub-region can improve the accuracy of the movement of the control sub-region and further improve the accuracy of seat control.

[0162] The second motion parameter is a parameter that adjusts the seat posture corresponding to the sub-region. Optionally, the parameter that adjusts the seat posture corresponding to the sub-region includes, but is not limited to, one or more of the following: controlling the sub-region of the seat to move forward and backward, controlling the sub-region of the seat to move up and down, and controlling the sub-region of the seat to move left and right.

[0163] Wherein, if the user's body part corresponding to the sub-region is different, the corresponding first motion parameter will also be different.
