The embodiment of the application provides a control method of a vehicle seat, which is applied to the vehicle seat. As shown in fig. 3, the control method of the vehicle seat includes:

s301, determining the space requirement of the target seat to be adjusted to the zero gravity state according to the request instruction.

The request instruction is directly input by the user through a key, an interactive screen, a smart phone or other intelligent terminal equipment. In the case of a plurality of vehicle seats which can be adjusted to the zero-gravity state, the request command can be used to determine the target seat in the vehicle seats and thus the space requirement for adjusting the target seat to the zero-gravity state. It will be appreciated that the space requirements for a vehicle seat in different positions to adjust to a zero gravity condition are different. Such as seats in the middle row, while there is a need for front and rear rows of seats; in the case where the vehicle seat is in the front-most row or the rear-most row, there is no need for both the front-row seat and the rear-row seat. Therefore, the position of the target seat is determined according to the request instruction, and the current space requirement can be accurately determined. In the implementation process, a mapping relationship between the vehicle seats at different positions and the space requirement is established. And determining the current space requirement according to the determined target seat and the mapping relation. Under the condition that only one vehicle seat is in the zero gravity state, the space requirement in the zero gravity state is directly set, and under the condition that a request instruction is received, the set space requirement is called.

S302, determining whether the adjacent seat meets space requirements according to the current state of the adjacent seat of the target seat.

For example, whether the adjacent seat meets space requirements may be determined based on the load condition and current configuration of the adjacent seat. More specifically, a judgment can be made on whether the adjacent seat has a load or not, and under the condition of the load, whether the adjacent seat meets the space requirement or not is determined at least according to the condition of the load; in the absence of a load, it is determined whether the adjacent seat meets space requirements based at least on the shape of the seat. Therefore, different actual conditions can be distinguished, and accurate judgment can be made on whether the current condition of the adjacent seat can influence the target seat to be adjusted to the zero gravity state.

And S303, if the target seat is satisfied, adjusting the target seat to a zero gravity state.

In some embodiments, adjusting the target seat to a zero gravity state includes: the backrest part, the seat cushion part and the leg support part are controlled to move, so that the included angle between the backrest part and the seat cushion part is a first included angle, and the included angle between the seat cushion part and the leg support part is a second included angle. The first included angle and the second included angle are fixed values which are set in advance, and the first included angle and the second included angle are directly called when the zero gravity mode is opened. Wherein, the value range of the first included angle is [121 degrees, 135 degrees ], and the value range of the second included angle is [135 degrees, 141 degrees ]. For example, the first angle may be set directly to 128 ° and the second angle to 133 °. The user may make further adjustments to the settings based on his own experience. In this way, when a request instruction for adjusting the target seat to the zero gravity state is received, the angle between the backrest portion and the seat cushion portion and the angle between the seat cushion portion and the leg rest portion are adjusted to the set values, and more comfortable riding experience can be provided to the user than in the conventional seat configuration. In some embodiments, adjusting the target seat to the zero gravity state further comprises: the leg rest is controlled to extend to a set target length. The target length is a fixed value stored in advance, so that leg support can be provided for a user, and riding experience of the user is optimized.

In some embodiments, where the target seat includes a controllably movable back portion, seat cushion portion, leg rest portion, adjusting the target seat to a zero gravity state includes: obtaining the body shape of a user; according to the body shape of the user, a first angle reference value between the backrest portion and the seat cushion portion, a second angle reference value between the seat cushion portion and the leg rest portion, and an extension length reference value of the leg rest portion are determined. The back rest part, the seat cushion part and the leg support part are controlled to move, so that the included angle between the back rest part and the seat cushion part meets a first angle reference value, the included angle between the seat cushion part and the leg support part meets a second angle reference value, and the extension length of the leg support part meets an extension length reference value. Wherein, the range of the first angle reference value is [121 degrees, 135 degrees ] ], and the range of the second angle reference value is [135 degrees, 141 degrees ] ]. In practical application, a first angle reference value and a second angle reference value corresponding to different user body types may be set in the value range, or the value range of the first angle reference value and the value range of the second angle reference value may be set. And determining a first angle reference value and a second angle reference value according to the body shape of the user actually riding the target seat, or determining a value range of the first angle reference value and a value range of the second angle reference value, and selecting the first angle reference value and the second angle reference value from the respective value ranges. Wherein, the larger the body type of the user, the larger the first angle reference value and the larger the second angle reference value. For example, when the user has a large body size, the first angle reference value is set to 132 ° and the second angle reference value is set to 138 °; when the user body type is a midbody type, setting a first angle reference value to be 128 degrees and setting a second angle reference value to be 133 degrees; in the case where the user is of a small size, the first angle reference value is set to 124 °, and the second angle reference value is set to 128 °. Therefore, the specific parameters of the zero gravity mode are determined according to the body types of the users taking the target seats, and different requirements of the users with different body types are considered, so that the operation of the zero gravity mode can be more in line with the requirements of the current users, and the user experience is optimized.

In the zero gravity mode, the included angle between the backrest part and the seat cushion part and the included angle between the seat cushion part and the leg support part are required to be maintained within a certain angle range, and meanwhile, the included angle between the backrest part and the bottom surface of the vehicle is required to be ensured to be larger than or equal to 20 degrees, and the included angle between the seat cushion part and the bottom surface of the vehicle is required to be larger than or equal to 20 degrees. In this way, it is possible to avoid the target seat from being excessively tilted forward or backward, resulting in discomfort to the user riding the target seat.

Preferably, controlling the movement of the backrest portion, the seat cushion portion, and the leg rest portion includes: the movement of the backrest part and the leg support part is controlled first, and then the movement of the seat cushion part is controlled. During the zero gravity mode of operation of the vehicle seat, the movement region of the seat cushion portion is generally rotated toward the side closer to the backrest portion, i.e., lifted away from the backrest portion; the movement tendency of the back portion is generally such that the back portion rotates to the side away from the seat cushion portion, i.e., the side away from the seat cushion portion falls rearward. In the unfolding process of the target seat, the seat cushion part is controlled to move finally, so that the situation that the user feels crowded and uncomfortable due to the fact that the included angle between the backrest part and the seat cushion part is too small in the unfolding process can be avoided, and the comfort level of the user can be guaranteed.

In some embodiments, obtaining the user profile includes: and obtaining the characteristic parameters of the user, and determining the body type of the user according to the characteristic parameters. Wherein the characteristic parameters of the user comprise one or more of height, weight and gender of the user. In practical application, each characteristic parameter can be directly input by a user through set keys, interaction screens, intelligent terminal equipment including intelligent mobile phones and other input equipment, so that accurate user data can be directly obtained, the accuracy of determining the body type of the user is ensured, and the accuracy of adjusting the subsequent vehicle seats is ensured. The characteristic parameters can also be acquired by the sensing device. Specifically, the height parameter may be obtained by an image sensor and/or an infrared sensor, the weight may be obtained by a weight sensor provided at the bottom of the vehicle seat, and the sex may be obtained by analyzing voiceprints after the sound sensor obtains sound. Therefore, accurate user characteristic parameters can be obtained without user input, and the noninductive control can be realized, so that the user experience is optimized. In other embodiments, body types may also be entered by the user directly through the input device.

Here, the case where the characteristic parameters are height, weight, height and weight, and sex, respectively, will be described.

Under the condition that the characteristic parameter is the height of the user, determining the body type of the user according to the characteristic parameter, and determining a first angle reference value between the backrest part and the seat cushion part, a second angle reference value between the seat cushion part and the leg support part and an extension length reference value of the leg support part according to the body type of the user, wherein the method comprises the following steps: under the condition that the height of the user is larger than or equal to a first height threshold value, determining that the user is large, determining that a first angle reference value is a first angle, determining that a second angle reference value is a second angle, and determining that the extension length reference value of the leg support part is a first length; under the condition that the height of the user is smaller than a first height threshold and larger than a second height threshold, determining that the user is of a midbody type, determining that a first angle reference value is a third angle, a second angle reference value is a fourth angle, and an extension length reference value of the leg support part is a second length; and under the condition that the height of the user is smaller than or equal to a third height threshold value, determining that the user is in a small body shape, determining that the first angle reference value is a fifth angle, determining that the second angle reference value is a sixth angle, and determining that the extension length reference value of the leg support part is a third length. Wherein the first angle is greater than the third angle, and the third angle is greater than the fifth angle; the second angle is greater than the fourth angle, and the fourth angle is greater than the sixth angle; the first length is greater than the second length, and the second length is greater than the third length. For example, the first height threshold may be set to 185cm and the second height threshold may be set to 170cm.

When the characteristic parameter is the weight of the user, determining the body type of the user according to the characteristic parameter, and determining a first angle reference value between the backrest part and the seat cushion part, a second angle reference value between the seat cushion part and the leg rest part, and an extension length reference value of the leg rest part according to the body type of the user, comprising: under the condition that the body weight of the user is greater than or equal to a first weight threshold, determining that the user is large, determining that a first angle reference value is a first angle, determining that a second angle reference value is a second angle, and determining that the extension length reference value of the leg support part is a first length; under the condition that the weight of the user is smaller than the first weight threshold and larger than the second weight threshold, determining that the user is of a midbody type, determining that a first angle reference value is a third angle, a second angle reference value is a fourth angle, and an extension length reference value of the leg support is a second length; and under the condition that the weight of the user is less than or equal to a third weight threshold value, determining that the user is in a small body shape, determining that the first angle reference value is a fifth angle, the second angle reference value is a sixth angle, and the extension length reference value of the leg rest is a third length.

Under the condition that the characteristic parameters are the height and the weight of the user, determining the body type of the user according to the characteristic parameters, and determining a first angle reference value between the backrest part and the seat cushion part, a second angle reference value between the seat cushion part and the leg rest part and an extension length reference value of the leg rest part according to the body type of the user, wherein the method comprises the following steps: when the height of the user is greater than or equal to a first height threshold value and the weight of the user is greater than or equal to a first weight threshold value, determining that the user is large, determining that a first angle reference value is a first angle, determining that a second angle reference value is a second angle, and determining that the extension length reference value of the leg support is a first length; when the height of the user is smaller than the first height threshold and larger than the second height threshold, and the weight of the user is smaller than the first weight threshold and larger than the second weight threshold, determining that the user is of a midbody type, determining that a first angle reference value is of a third angle, a second angle reference value is of a fourth angle, and an extension length reference value of the leg support is of a second length; and when the height of the user is smaller than or equal to the third height threshold value, and when the weight of the user is smaller than or equal to the third weight threshold value, determining that the user is in a small body shape, determining that the first angle reference value is in a fifth angle, determining that the second angle reference value is in a sixth angle, and determining that the extension length reference value of the leg rest is in a third length. Wherein the first angle is greater than the third angle, and the third angle is greater than the fifth angle; the second angle is greater than the fourth angle, and the fourth angle is greater than the sixth angle; the first length is greater than the second length, and the second length is greater than the third length. For example, the first height threshold may be set to 185cm and the second height threshold may be set to 170cm; the first weight threshold was 80kg and the second weight threshold was 65kg. In this case, if the height and weight of the user correspond to different body types, the body type corresponding to the height of the user is preferentially determined as the body type of the user.

In the case that the characteristic parameter is sex, determining a user body type according to the characteristic parameter, and determining a first angle reference value between the backrest portion and the seat cushion portion, a second angle reference value between the seat cushion portion and the leg rest portion, and an extension length reference value of the leg rest portion according to the user body type, comprising: under the condition that the user is a male, determining that the user is large, determining that a first angle reference value is a seventh angle, determining that a second angle reference value is an eighth angle, and determining that an extension length reference value of the leg support part is a fourth length; and under the condition that the user is female, determining that the user is small, determining that the first angle reference value is a ninth angle, determining that the second angle reference value is a tenth angle, and determining that the extending length reference value of the leg rest is a fifth length. Wherein the seventh angle is greater than the ninth angle, the eighth angle is greater than the tenth angle, and the fourth length is greater than the third length. Therefore, the sex determination method and the sex determination system can determine the more accurate user body type through the sex of the user in consideration of the common difference of the body types between the male and the female, and are used for controlling the zero gravity mode and improving the operation accuracy of the zero gravity mode.

It will be appreciated that the body types of the users may be divided according to actual needs, not limited to the above examples. In addition to the above-described division of the user body types into a large body type, a medium body type, and a small body type, in other embodiments, the body type may be divided into two body types of a large body type and a small body type, or into a plurality of body types greater than three. And correspondingly establishing different mapping relations between the characteristic parameters and the body types for different body type division modes, namely determining the body types of the user according to the characteristic parameters of the current user.

In some embodiments, if the target seat further comprises a controllably movable headrest portion, adjusting the target seat to a zero gravity state further comprises: a first height reference value of the headrest portion is determined according to the user's body type. And controlling the headrest part to move so that the height of the headrest part meets the first height reference value. In the process of controlling the headrest to move so that the height of the headrest meets the first height reference value, the headrest moves in the headrest up-down adjusting shaft direction 42 so as to adapt to the head positions of different users and optimize the riding experience of the users. The larger the user body type is, the higher the first height reference value of the headrest part is, so that the height of the headrest part is matched with the position of the head of the user currently sitting on the target seat, the head of the user can be better supported, and the user experience is optimized. Further, in some embodiments, after controlling the movement of the headrest portion such that the height of the headrest portion satisfies the first height reference value, the control method further includes: and obtaining the pressure distribution condition on the headrest part, calculating a pressure average value, and adjusting the front and rear positions of the headrest part according to the pressure average value. More specifically, in the case where the pressure average value is smaller than the pressure threshold value, the headrest portion is adjusted forward; and/or, in the event that the pressure average is greater than the pressure threshold, adjusting the headrest portion rearward. The adjustment of the front-rear position of the headrest portion is herein referred to as controlling the headrest portion to move in the headrest front-rear adjustment axial direction 41. The forward adjustment is to control the headrest portion to move towards the direction higher than the plane of the backrest portion, and the backward adjustment is to control the headrest portion to move towards the direction lower than the plane of the backrest portion. In this way, on the basis of the up-and-down movement of the headrest portion, a judgment is made on the comfort level of the user according to the pressure distribution on the headrest portion. If the pressure average is too small, it is indicated that the headrest portion does not provide sufficient support for the user's head, and forward adjustment is required to approach the user's head, thereby optimizing the support effect for the user's head.

In some embodiments, if the target seat further includes a controllably movable lumbar support, adjusting the target seat to a zero gravity state includes: determining a second height reference value of the waist support part according to the body shape of the user; and controlling the waist support part to move so that the height of the waist support part meets the second height reference value. In the process of controlling the waist support portion to move so that the height of the waist support portion meets the second height reference value, the waist support portion moves on the waist support up-down adjusting shaft direction 44 so as to use different waist support requirements of different users, and the riding experience of the users is optimized.

And S304, if the current state of the adjacent seat is not satisfied, adjusting the adjacent seat to avoid according to the current state of the adjacent seat.

In some embodiments, the vehicle seat comprises a plurality of rows of seats; the target seat includes one of the front, middle and rear rows of seats among the plurality of rows of seats; adjusting the adjacent seats to avoid according to the current state of the adjacent seats, comprising: when the adjacent seats are the seats positioned in the rear row and the back angle of the seats in the rear row is smaller than or equal to the first back angle reference value, the back part of the seats in the rear row is adjusted, so that the included angle between the back part of the seats in the rear row and the seat cushion part meets the first back angle reference value; and/or controlling the rearward row of seats to move rearward relative to the forward row of seats. The first chair back angle reference value is a set fixed value, for example, 93.6 degrees, and the angle is an angle threshold value which does not influence the front-row seat to be opened to a zero gravity mode in the conventional use process through experimental measurement. In other embodiments, if the first angle reference value between the backrest portion and the seat cushion portion, the second angle reference value between the seat cushion portion and the leg rest portion, and the extension length reference value of the leg rest portion are determined according to the user's body type, the first seatback angle reference value may be determined according to the first angle reference value. Specifically, the larger the first angle reference value is, the larger the first chair back angle reference value is; the smaller the first angle reference value, the smaller the first seatback angle reference value. The different first angle reference values correspond to different backrest heights of the target seat, and thus the space required for the target seat to deploy to the zero gravity state is also different. The greater the first angle reference, the lower the backrest portion, and the greater the rear empty space required to ensure deployment of the target seat, and therefore the greater the angle to which the rear seat is deployed, the less the deployment of the target seat will be affected. The first chair back angle reference value is determined according to the first angle reference value, so that the fact that the threshold value judged by a user is consistent with the actual condition of the current chair can be guaranteed, and the judging accuracy is further improved. In the actual application process, a mapping relation between the first angle reference value and the first chair back angle reference value can be established in advance, the mapping relation is stored, and the mapping relation is called according to the current first angle reference value in the actual operation process.

In some embodiments, the vehicle seat comprises a plurality of rows of seats; the target seat includes one of the front, middle and rear rows of seats among the plurality of rows of seats; adjusting the adjacent seats to avoid according to the current state of the adjacent seats, comprising: when the adjacent seat is determined to be the seat positioned in the front row and the front row has a load, the movable range is determined according to the load condition of the front row seat, and the front row seat is controlled to move forward according to the movable range. Because the leg rest needs to be unfolded and support the legs of the user in the zero gravity mode, compared with the normal sitting posture, the front of the target seat needs to have a larger space, and if the current space is insufficient, the adjacent seat positioned in the front row needs to move forwards along the sliding rail. If the front row seat is loaded, the movement space of the seat positioned in the front row is likely to be affected. At the moment, the movable range is determined according to the load condition of the front-row seat, and the front-row seat is controlled to move forwards according to the movable range, so that collision in the moving process of the front-row seat can be avoided. The movable range is here indicated by a movable distance in the slide front-rear adjustment axial direction 46. Specifically, the movable range is determined according to the load condition of the front seat, including determining that the load of the front seat is a human body or an object. If the vehicle is a human body, the movable distance of the seat is determined according to the body shape of the occupant. I.e., the larger the occupant's body size, the smaller the movable distance. If the object is an object, the movable distance of the seat is determined according to the height of the object in the vertical direction and the length of the object in the slide rail front-rear adjustment axial direction 46. The greater the height of the object in the vertical direction, the smaller the adjustable distance; the greater the length of the object in the front-rear adjusting shaft direction of the sliding rail is, the smaller the adjustable distance is. Controlling forward movement of the front row of seats according to the movable range includes: an adjustment distance that requires movement of the front seat is determined, and in the event that the adjustment distance is less than or equal to the adjustable distance, the front seat is controlled to move forward by the adjustment distance. In the case where the adjustment distance is greater than the adjustable distance, the front seat is determined to be moved forward by the adjustable distance, and the target seat is controlled to retreat in the slide rail front adjustment axial direction 46 until the required adjustment distance thereof is satisfied. In this way, the collision of the load can be prevented under the condition that the control target seat runs in the zero gravity mode.

In addition, in the case where the current space is insufficient, it is necessary that the adjacent seats in the front row move forward along the slide rails and the seats in the front row have no load, the moving distance of the seats in the front row is determined according to the body shape of the user carried by the target seat, and the front row seats are controlled to move forward by the moving distance. Specifically, the larger the body size of the user, the greater the moving distance of the seat positioned in the front row is determined. In practical application, the front row seat slides back and forth along the sliding rail, and the moving distance is determined to be 80-100% of the total length of the sliding rail under the condition that the body shape of a user is a large body shape; in the case where the body shape of the user is a midbody shape, the moving distance is determined to be 20% to 80%; in the case where the body shape of the user is a small body shape, the moving distance is determined to be less than 20%. The first distance is greater than the second distance, and the second distance is greater than the third distance.

In some embodiments, the control method for a vehicle seat further includes, in controlling forward movement of the front seat according to the movable range: and determining whether a first stopping instruction for controlling the adjacent seats to stop avoiding is received. And when the first stopping instruction is received, controlling the adjacent seats to stop avoiding, and locking the current position and the backrest angle. Thus, the adjusting process of the adjacent seats can be stopped in time according to the requirements of users. In some embodiments, during adjustment of the target seat to the zero gravity state, the control method further comprises: determining whether a second stop instruction for controlling the target seat to stop adjusting is received; and when receiving the second stopping instruction, controlling the target seat to stop, and locking the current state of the target seat. In this way, during adjustment of the target seat to the zero gravity state, whether or not the received stop instruction is monitored so as to stop the adjustment process in time when the user needs to stop adjusting the target seat due to discomfort or other reasons. The user can input the second stopping instruction through the set key operation, interactive screen operation, terminal equipment input and other modes.

S305, when the space requirement can be met after the adjacent seats are avoided, the target seat is adjusted to a zero gravity state.

By adopting the control method of the vehicle seat, when the request instruction is received, the space requirement for unfolding the target seat to the zero gravity state is determined, and whether the adjacent seat meets the space requirement or not is judged according to the current state of the adjacent seat. If the adjacent seats meet the space requirement, the situation that the target seat is opened to the target mode at the moment can not cause interference to other objects or users is indicated, and the unfolding of the target seat is directly controlled at the moment. If the adjacent seat does not meet the space requirement, adjustment is made according to the current state of the adjacent seat so as to avoid. When the adjacent seats are avoided to meet the space requirement, the target seat is adjusted to be in a zero gravity state. Therefore, interference to other objects or users can be avoided in the use process of the target seat, collision is avoided, safety is guaranteed, and user experience is optimized.

In some embodiments, during adjustment of the target seat to the zero gravity state, the control method further comprises: determining whether an object is located in the anti-pinch area of the target seat; when the object is determined to be in the anti-pinch area of the target seat, controlling each axial reversal corresponding to the target seat and sending out reminding information. The anti-pinch area is at least part of the area through which the target seat needs to pass when being adjusted to the zero gravity state. If an object exists in the anti-pinch area, the object is possibly pinched in the process of adjusting the target seat to a zero gravity state, damage is caused to the object and the target seat, and even a user is accidentally injured, and at the moment, each axial reverse rotation of the target seat is controlled and prompt information is sent to prompt the user to protect the object and the user.

In some embodiments, after the target seat is adjusted to the zero gravity state, the control method further comprises: acquiring the running speed of the vehicle; when it is determined that the running speed is equal to or greater than the speed reference value, a safety alarm is issued. A user riding a target seat in a zero gravity state may have a lower reaction speed and a relatively low degree of crashworthiness of the target seat than in a normal riding process. Therefore, the speed reference value is set to judge the running speed of the current vehicle, and if the running speed is higher, a safety alarm is sent out to prompt a user to reduce the speed or improve vigilance, so that the safety is improved. Wherein the speed reference value is determined according to at least part of the wearing condition of the safety belt, the safety configuration of the vehicle and the user identity information. Specifically, determining the speed reference value according to the wearing condition of the safety belt includes: detecting whether the safety belt is buckled through the safety belt buckle state switch 24, and if the user wears the safety belt, corresponding to a higher speed reference value; if the user is not wearing the seat belt, a lower speed reference value is corresponding. Determining the speed reference value according to the safety configuration of the vehicle includes: the safety arrangement of the vehicle is obtained, wherein the safety arrangement comprises a side airbag, a far-end airbag, a seat cushion collapse mechanism and the like, and the larger the number of the safety arrangements is, the larger the speed reference value is. More security configurations can provide more comprehensive and higher-level security protection for users, and at the moment, the appropriate improvement of the speed reference value can ensure the security of the users while reducing the speed limit. Determining the speed reference value according to the user identity information comprises: setting a common user and a special protection user, determining whether the user is the common user or the special protection user according to user identity information, and determining a lower speed reference value under the condition that the user is the special protection user so as to ensure the safety of the special protection user; in the case that the user is a normal user, a higher speed reference is determined to reduce the limitation on the running speed. The special protection users can be special groups such as children, old people, pregnant women and the like, and can also be special people set by the users.

Referring to fig. 4, in the step S302, it is determined whether the adjacent seat meets the space requirement according to the current state of the adjacent seat of the target seat, including steps S321 to S325, specifically:

s321, determining whether the adjacent seat has a load.

S322, when the load is determined, determining that the bearing object of the adjacent seat is a human body or an object.

S323, when the object borne by the adjacent seat is determined to be a human body, determining whether the target seat can be adjusted to a zero gravity state according to the body type of the user on the target seat and the pose of the adjacent seat; wherein the pose of the adjacent seat includes the back angle of the adjacent seat and the position in each movement axis.

In some embodiments, determining whether the target seat can be adjusted to a zero gravity state based on the body shape of the user on the target seat, and the pose of the adjacent seat, comprises: the backrest angle requirements for adjacent seats and the position requirements in each movement axis are determined according to the body shape of the user on the target seat. If the adjacent seats meet the backrest angle requirement and meet the position requirement on each movement axis, the target seat is adjusted to a zero gravity state; and if the adjacent seats do not meet the backrest angle requirement or the position requirement on each movement axis, controlling the adjacent seats to avoid. Here, the adjacent seats are retracted, i.e. the adjacent seats adjust the backrest angle and/or the position requirement in the respective movement axis, until the backrest angle requirement and the position requirement in the respective movement axis described above are fulfilled. The users with different body types occupy different spaces, the corresponding specific parameters of the zero gravity state are different, and the requirements on the adjacent seats are different. Therefore, determining the specific pose requirements of the adjacent seats according to the body types of the users on the target seats is beneficial to improving the accuracy of the judging process.

In some embodiments, determining the back angle requirement for the adjacent seat based on the body shape of the user on the target seat includes: and determining a first chair back angle reference value corresponding to the adjacent chair positioned in the rear row and/or a second chair back angle reference value corresponding to the adjacent chair positioned in the front row according to the body shape of the user on the target chair. If the backrest angle of the adjacent seat positioned in the rear row is greater than or equal to the first backrest angle reference value, determining that the adjacent seat positioned in the rear row meets the backrest angle requirement. If the backrest angle of the adjacent seat positioned in the front row is smaller than or equal to the second backrest angle reference value, determining that the adjacent seat positioned in the front row meets the backrest angle requirement. The larger the body type of the user is, the larger the first chair back angle reference value is, and the smaller the second chair back angle reference value is.

In some embodiments, the position requirement includes a section in the slide rail fore-aft adjustment axis 46, which is the section between the boundary position furthest from the target seat and the critical position. Determining the upward position requirements for each axis of motion of the adjacent seats based on the body shape of the user on the target seat includes: the larger the user body size, the closer the critical position is to the far-end, and the smaller the interval length is. In some embodiments, the adjacent seats are provided with leg rest portions, and the position requirement further includes a section in the leg rest extension adjustment axial direction 48 and the leg rest angle adjustment axial direction 49, and the section meeting the position requirement in the leg rest extension adjustment axial direction 48 is a length section between the shortest length and the critical length of the leg rest. Determining the upward position requirements for each axis of motion of the adjacent seats based on the body shape of the user on the target seat includes: the larger the body shape of the user on the target seat is, the shorter the critical length is, and the smaller the length interval is; in the leg rest angle adjustment axis 49, the interval meeting the position requirement is the angle interval between the minimum opening angle and the critical angle. Determining the upward position requirements for each axis of motion of the adjacent seats based on the body shape of the user on the target seat includes: the larger the body size of the user on the target seat, the smaller the critical angle and the smaller the angle interval. Thus, the accurate position requirement can be determined according to the body type of the user on the target seat, and the actual situation is consistent with the judging result.

S324, when the object carried by the adjacent seats is determined to be an object, whether the target seat can be adjusted to a zero gravity state or not is determined according to the physical parameters of the object.

In some embodiments, determining whether the target seat can be adjusted to a zero gravity state based on a physical parameter of the object comprises: acquiring the height of an object; if the height of the object is smaller than or equal to the first set height, the target seat is adjusted to be in a zero gravity state; if the height of the object is larger than the first set height and smaller than the second set height, controlling adjacent seats to avoid; if the height of the object is greater than the second set height, it is determined that the target seat cannot be adjusted to the zero gravity state. Like this, through setting up first settlement height and second settlement height, can be to the condition that need not dodge can run zero gravity state, dodge the back and can run zero gravity state and dodge the back and still can not run zero gravity state make the differentiation to avoid effectively producing the condition of interference at the regulation in-process of target seat. Wherein the first set height is less than the second set height. For reference, the first set height is 0.8m, with the plane in which the rotation axis between the backrest portion and the cushion portion of the target seat is located as the reference plane, and the reference plane is noted as 0 m.

In some embodiments, determining whether the target seat can be adjusted to a zero gravity state based on a physical parameter of the object comprises: determining whether the object can be compressed; if the object can be compressed, adjusting the target seat to a zero gravity state; if the object is not compressible, it is determined whether the target seat can be adjusted to a zero gravity state based on the height of the object. In some cases, the object carried by the adjacent seat may be a soft clothing or other compressible object, where even its current height is high, it does not affect the zero gravity operation. Therefore, according to whether the bearing object can be compressed, more accurate judgment can be made on whether the target seat can be adjusted to the zero gravity state, and the zero gravity state experience is provided for a user on the premise of not damaging the vehicle body and the object. In the application process, the image sensor can be used for obtaining the image information of the object on the adjacent seat, and judging whether the current object is a compressible object or not according to the image information and a preset image database; or, whether the object can be compressed or not can be input by the user through the input device, so that the accuracy of the physical parameters is improved. Here, in the case where the object is incompressible, it is determined whether the target seat can be adjusted to the zero gravity state according to the height of the object, as in the foregoing procedure. Namely: if the height of the object is smaller than or equal to the first set height, the target seat is adjusted to be in a zero gravity state; if the height of the object is larger than the first set height and smaller than the second set height, controlling adjacent seats to avoid; if the height of the object is greater than the second set height, it is determined that the target seat cannot be adjusted to the zero gravity state.

And S325, when no load is determined, determining whether the target seat can be adjusted to the zero gravity state according to the current state of the adjacent seats.

In some embodiments, determining whether the target seat can be adjusted to a zero gravity state based on the current state of the adjacent seat includes: it is determined whether the adjacent seat is currently in a locked state. And if the adjacent seats are in the locking state currently, acquiring the chair back angles of the adjacent seats, and determining whether to enter a zero gravity state according to the chair back angles of the adjacent seats. And when the back angle of the adjacent seat is determined to enter a zero gravity state, controlling the target seat to be adjusted to the zero gravity state. If the adjacent seat is in the non-locking state currently, further determining whether the adjacent seat is in the stow state; the control target seat is adjusted to a zero gravity state upon determining that the adjacent seat is in the stowed state. Firstly, judging whether the adjacent seat is in a locking state, if the seat is locked, directly determining whether the adjacent seat can interfere the unfolding of the target seat according to the chair back angle of the adjacent seat. If the adjacent seat is not locked, the target seat is adjusted to the zero gravity state only if the adjacent seat is in the stowed state. Wherein the target seat is unfolded to the zero gravity state as shown in state a in fig. 5, and the stow state of the adjacent seat is shown in state B in fig. 5. Thus, the movement of the seat in the unlocked state in the running process of the vehicle can be avoided, and the damage to the seat or a user can be avoided.

In some embodiments, determining whether to enter a zero gravity mode based on the back angle of an adjacent seat includes: when the adjacent seat is positioned at the rear row of the target seat, if the backrest angle of the adjacent seat is greater than or equal to the first backrest angle reference value, the target seat is determined to be capable of entering the zero gravity mode. And/or determining that the target seat can enter the zero gravity mode if the backrest angle of the adjacent seat is less than or equal to the second backrest angle reference value when the adjacent seat is positioned in the front row of the target seat. Therefore, different judgment standards are selected for adjacent seats at different positions, so that the accuracy of judgment is improved.

Therefore, whether the target seat can be adjusted to the zero gravity state or not is judged according to the existence of the load and the type of the load, the judgment can be ensured to be more in line with the current actual situation, the accuracy of the judgment result is improved, the accuracy of the control of the target seat is further improved, and the interference generated in the process of opening the target seat to the zero gravity state is avoided.

In some embodiments, in the process of controlling the adjacent seat to avoid, the control method of the vehicle seat further includes: determining whether a first stopping instruction for controlling the adjacent seats to stop avoiding is received; and when the first stopping instruction is received, controlling the adjacent seats to stop avoiding, and locking the current position and the backrest angle. Therefore, the adjusting process of the adjacent seats can be stopped in time according to the requirements of users, and discomfort of the users is avoided.

In some embodiments, after controlling the adjacent seat to stop avoiding and locking the current position and the backrest angle, the method further comprises: judging whether the positions of the current adjacent seats meet the position requirement and whether the backrest angle meets the backrest angle requirement. If the positions of the current adjacent seats meet the position requirement and the backrest angle meets the backrest angle requirement, the target seat is adjusted to be in a zero gravity state; if the position of the current adjacent seat does not meet the position requirement or the backrest angle does not meet the backrest angle requirement, determining that the target seat cannot be adjusted to the zero gravity state. In this way, in the case that the user terminates the avoidance process, a further determination is made as to whether the back angle requirement and the position requirement are met in the case after the current avoidance, so that the target seat is adjusted to the zero gravity state if the current avoidance level that may exist is sufficient to adjust the target seat to the zero gravity state. The backrest angle requirement and the backrest position requirement are determined according to the body shape of the user on the target seat, and the backrest angle requirement and the backrest position requirement are the same as the determination process, and the repeated description is omitted. Further, after it is determined that the target seat cannot be adjusted to the zero gravity state, the adjacent seat may be automatically restored to the original position before adjustment, or, in the case of receiving a restoration instruction input by the user, restored to the original position, thereby improving comfort of the occupant on the adjacent seat.

As shown in fig. 6, the present application provides another control method of a vehicle seat, including:

s601, determining the space requirement of the target seat adjusted to the zero gravity state according to the request instruction.

S602, determining whether the adjacent seat meets the space requirement according to the current state of the adjacent seat of the target seat.

And S603, if the target seat is satisfied, adjusting the target seat to a zero gravity state.

And S604, if the current state of the adjacent seat is not satisfied, adjusting the adjacent seat to avoid according to the current state of the adjacent seat.

S605, when the space requirement can be met after the adjacent seats are avoided, the target seat is adjusted to be in a zero gravity state.

S606, acquiring actual pressure distribution of each area of the target seat.

Here, the actual pressure distribution of each region of the target seat is acquired by the pressure sensor provided in each region of the target seat. Specifically, a plurality of pressure sensing devices are arranged in each area of the target seat, and pressure values of a plurality of positions in each area are detected, so that the actual pressure distribution of each area of the target seat is determined.

S607, it is determined whether the uniformity of the actual pressure distribution of each region of the target seat satisfies zero gravity uniformity.

The uniformity degree of the actual pressure distribution can be represented by standard deviation, variance or variation coefficient of a plurality of pressure values in each region, a threshold corresponding to the current representation mode is determined, and whether the actual pressure distribution meets zero gravity uniformity is judged according to the size between the actual calculated value and the threshold. For example, after obtaining a plurality of pressure values of the seat cushion portion, calculating a standard deviation of the plurality of pressure values, and if the calculated standard deviation is greater than a standard deviation threshold value, determining that the uniformity of the actual pressure distribution of the seat cushion portion does not satisfy zero gravity uniformity; if the calculated standard deviation is less than or equal to the standard deviation threshold value, it is determined that the uniformity of the actual pressure distribution of the seat cushion portion satisfies the zero gravity uniformity. For different regions, different thresholds may be set to determine so as to adapt to uniformity requirements of different degrees for different regions.

And S608, when the actual pressure distribution does not meet the zero gravity uniformity, correspondingly adjusting each axial parameter of the corresponding area of the target seat to enable the actual pressure distribution to meet the zero gravity pressure distribution.

When the actual pressure distribution does not meet the zero gravity uniformity, determining an area which does not meet the zero gravity uniformity as a target area, firstly adjusting the target area, and if the pressure distribution of the target area still does not meet the zero gravity uniformity after adjustment, adjusting the target area and other areas, and carrying out multiple adaptive adjustment by comparing the change conditions of the uniformity before and after adjustment so as to enable the uniformity of the actual pressure distribution of each area to be gradually close to and finally meet the zero gravity uniformity.

In this way, taking individual differences among users into consideration, after the target seat has been adjusted to a zero gravity state, a judgment is made on the uniformity degree of the actual pressure distribution of each region of the target seat, and an adaptive adjustment is made, which is beneficial to optimizing the riding experience of the current user.
