[0047] The following further describes the detailed implementation manners of the present invention with reference to the drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0048] As Figure 1 shown is a flowchart of the working process of a vehicle flank adjustment method according to an embodiment of the present invention, including:

[0049] Step S101, obtaining multiple pressure values of a back pressure sensor array provided on a backrest of a vehicle seat, where the back pressure sensor array includes multiple back pressure sensors arranged in an array;

[0050] Step S102, determining the width of an occupant's back based on the pressure values;

[0051] Step S103, controlling the flanks on both sides of the backrest to perform a wrapping operation according to the width of the occupant's back.

[0052] Specifically, the present invention can be applied to an electronic device with processing capabilities, such as a controller of a vehicle. For example, an electronic control unit (ECU) of a vehicle.

[0053] First, step S101 is executed to obtain multiple pressure values of a back pressure sensor array provided on the backrest of the vehicle seat. The back pressure sensor array includes multiple back pressure sensors arranged in an array.

[0054] Specifically, as Figure 3 shown, a back pressure sensor array 1 is provided on the backrest 10 of the seat back. The back pressure sensor array 1 includes multiple back pressure sensors 121 arranged in an array. Figure 3 Each red dot on the middle backrest 10 is a back pressure sensor 121. Each back pressure sensor 121 outputs the detected pressure value. The back pressure sensor 121 can be used to detect the width of the occupant's back.

[0055] Then, step S102 is executed to determine the width of the occupant's back based on the pressure values.

[0056] Specifically, the back pressure sensor detects the pressure generated when the occupant's back contacts the backrest. By extracting the pressure values output by the back pressure sensor, a pressure value matrix is formed. Then, the width of the occupant's back is further calculated based on the pressure value matrix.

[0057] Finally, step S103 is executed to control the wrapping operation of the flanks on both sides of the backrest according to the width of the occupant's back.

[0058] As Figure 3 shown, flanks 20 are also provided on both sides of the backrest 10. The flanks 20 on both sides wrap the occupant. According to the width of the occupant's back, the tightness of the wrapping of the flanks 20 on the occupant is adjusted.

[0059] In the present invention, a pressure sensor is provided on the seat backrest of the vehicle. By obtaining multiple pressure values of the back pressure sensor array on the seat backrest, the width of the occupant's back is determined. Thus, according to the width of the occupant's back, the wrapping operation of the flanks on both sides of the backrest is controlled, thereby improving the seat comfort and user experience.

[0060] As Figure 2 shown is a flowchart of a method for adjusting the flanks of a vehicle in another embodiment of the present invention, including:

[0061] Step S201, obtain multiple pressure values of a back pressure sensor array provided on the backrest of the vehicle seat. The back pressure sensor array includes multiple back pressure sensors arranged in an array. The back pressure sensor array extends in columns from the bottom of the backrest to the top of the backrest and in rows from the left side of the backrest to the right side of the backrest, arranging multiple rows and columns of back pressure sensors. With the direction from the bottom of the backrest to the top of the backrest as the height direction, multiple flank wrapping structures are provided on both flanks along the height direction.

[0062] Step S202: Based on the pressure value, determine the back widths of the occupants at multiple heights in the height direction.

[0063] Step S203: Based on the back widths of the occupants at each height, control the tightness of the flank wrapping structures at the corresponding heights on both sides of the backrest.

[0064] Specifically, first execute Step S201 to obtain multiple pressure values of the back pressure sensor array provided on the backrest of the vehicle seat.

[0065] As Figure 3 shown, a back pressure sensor array 1 is provided on the backrest 10. The back pressure sensor array 1 includes multiple back pressure sensors 121 arranged in an array. Figure 3 Each red dot on the backrest 10 in

[0066] is a back pressure sensor 121. Each back pressure sensor 121 outputs the detected pressure value. The back pressure sensor 121 can be used to detect the width of the occupant's back. Figure 3 The back pressure sensors 121 are arranged in rows and columns to form the back pressure sensor array 1. Among them, Figure 3 in Figure 3 , the direction extending from the bottom of the backrest to the top of the backrest is defined as the column, that is, the y - direction in

[0067] , simply referred to as the height direction. The direction extending from the left side of the backrest to the right side of the backrest is defined as the row, that is, the x - direction in

[0068] Specifically, with the direction extending from the bottom of the backrest to the top of the backrest as the column and the direction extending from the left side of the backrest to the right side of the backrest as the row, it includes:

[0069] Draw a first perpendicular line perpendicular to the bottom edge of the backrest and extending from the bottom of the backrest to the top of the backrest. Take the direction parallel to the first perpendicular line as the column. Draw a second perpendicular line perpendicular to the first perpendicular line and extending from the left side of the backrest to the right side of the backrest. Take the direction parallel to the second perpendicular line as the row.

[0070] As Figure 4 shown, the widths of human backs are different. There are humans with narrow backs and humans with wide backs. When the occupant's back contacts the contact surface of the backrest 10, a depression amount of the contact surface will be generated. Different back widths have different contact areas with the backrest. The contact length between the narrow - back human body 41 and the backrest 10 will be less than the contact length between the wide - back human body 42 and the backrest 10. Therefore, by detecting the pressure value of the back pressure sensor, it is possible to determine whether the position of the back pressure sensor is in contact with the occupant's back, and thus determine the back width of the occupant.

[0071] Then, step S202 is executed to determine the back widths of the occupants at multiple heights in the height direction based on the pressure value.

[0072] Specifically, the back of a human body has different widths at different height positions. By detecting the pressure values at different heights, the back width of the occupant at that height is determined.

[0073] Among them, the height position is the position in the height direction, that is, Figure 3 the position in the y direction in

[0074] In one embodiment, the determining the back widths of the occupants at multiple heights in the height direction based on the pressure value includes:

[0075] For each row in the back pressure sensor array, obtain the position of the back pressure sensor with the minimum non-zero pressure value on the left side of each row as the left departure point, and obtain the position of the back pressure sensor with the minimum non-zero pressure value on the right side of each row as the right departure point;

[0076] Calculate the distance between the left departure point and the right departure point of each row as the back width of the occupant at the height where each row is located.

[0077] Specifically, each row corresponds to a height position. Each row represents the pressure values in the horizontal direction ( Figure 3 in the Y direction in Figure 3 the back) at different height positions in the height direction. In the same row, that is, at the same height position, calculate the position of the back pressure sensor with the minimum non-zero pressure value on the left side as the left departure point, and the position of the back pressure sensor with the minimum non-zero pressure value on the right side as the right departure point. Among them, the minimum non-zero pressure value is the minimum value among the non-zero pressure values.

[0078] Among them, the left and right sides are distinguished by the center line of the backrest. The center line of the backrest is the geometric center line of the backrest, and the backrest is symmetric about the geometric center line of the backrest. The center line of the backrest is generally a line aligned with the natural curve of the human spine, that is, the center line of the backrest can be considered as the backrest spine line.

[0079] Obtain the position of the back pressure sensor with the minimum non-zero pressure value on the left side of each row as the left departure point, and obtain the position of the back pressure sensor with the minimum non-zero pressure value on the right side of each row as the right departure point. Specifically, obtain the position of the back pressure sensor with the minimum non-zero pressure value on the left side of the center line of the backrest of each row as the left departure point, and obtain the position of the back pressure sensor with the minimum non-zero pressure value on the right side of the center line of the backrest of each row as the right departure point.

[0080] As Figure 3 shown, the back pressure sensor array 1 is provided with at least one column of back pressure sensors along the center line of the backrest. The back pressure sensor arranged on the center line of the backrest can be used as the spine pressure sensor 15.

[0081] In one embodiment, calculating the distance between the left departure point and the right departure point of each row as the occupant's back width at the height where each row is located includes:

[0082] Establish a two-dimensional coordinate system for the back pressure sensor array, where the center line of the backrest is used as the first coordinate axis, and a straight line parallel to the rows of the back pressure sensor array is used as the second coordinate axis;

[0083] For each row in the back pressure sensor array, obtain the coordinates of the left departure point and the right departure point of each row on the two-dimensional coordinate system, and calculate the occupant's back width at the height where each row is located according to the coordinates of the left departure point and the right departure point.

[0084] Specifically, take all the columns corresponding to the back pressure sensors in the height direction ( Figure 3 Y direction in the middle) on the center line of the backrest (vertebral line) as the midpoint of the entire pressure matrix, and use this midpoint as the zero point of the coordinates of each row. That is, take the center line of the backrest as the first coordinate axis, for example, the y-axis, and a straight line parallel to the rows of the back pressure sensor array as the second coordinate axis, for example, the x-axis.

[0085] Thus, obtain the coordinates of the left and right departure points of the corresponding row B1(X1, Y1), B2(X2, Y2), and the back width L at this height can be calculated as:

[0086] Wherein, since in the same row, Y2 is the same as Y1, Y2 - Y1 = 0.

[0087] Then, perform step S203, and control the tightness of the flank wrapping structure at the corresponding height on both sides of the backrest based on the occupant's back width at each height.

[0088] Specifically, the flank wrapping structure includes but is not limited to a mechanical wrapping structure or a pneumatic wrapping structure. The mechanical wrapping structure can be a support structure driven by a motor. The pneumatic wrapping structure can be an airbag inflated or deflated by an air pump.

[0089] Among them, for the case where the flank wrapping structure is a mechanical wrapping structure, the tightness is the stroke of the motor shaft. For the case where the flank wrapping structure is a pneumatic wrapping structure, the tightness is the air pressure of the airbag.

[0090] In some embodiments, a flank wrapping structure is provided at the same height position of each backrest pressure sensor on the flank.

[0091] In this embodiment, a coordinate system is established to detect the back width of the occupant in real time through the coordinate system, and the wrapping tightness of different heights of the side wings is automatically adjusted according to the detection result, so as to achieve precise wrapping of the occupant's back and improve riding comfort. This embodiment can update the back width data according to the dynamic changes of the occupant (such as sitting posture adjustment), and dynamically adjust the tightness of the side wing sensors at the corresponding positions to ensure riding comfort.

[0092] In one embodiment, controlling the tightness of the side wing wrapping structures at the corresponding heights on both sides of the backrest based on the back width of the occupant at each height includes:

[0093] Controlling the side wings on both sides of the backrest to perform tightness adjustment on the side wing wrapping structures at each height, and adjusting the tightness to the tightness corresponding to the back width of the occupant at that height.

[0094] Specifically, one back width will be detected at each height, forming a width column. Each width corresponds to a tightness. The tightness corresponding to different widths can be determined in advance by calibration. Or multiple pairs of back widths and tightness are preset, and the fitting function of the tightness and the back width is determined by fitting. After detecting the back width at each height through the back pressure sensor, the tightness corresponding to the back width is determined by means such as looking up a table or substituting into the fitting function.

[0095] Then control the side wing wrapping structures at each height to adjust the tightness to the tightness corresponding to the back width of the occupant at that height. For example, control the motor stroke at each height to be the stroke corresponding to the back width of the occupant at that height, or control the air pressure of the airbag at each height to be the air pressure corresponding to the back width of the occupant at that height.

[0096] This embodiment sets the corresponding tightness for the back width of the occupant at each height, so as to more precisely adapt to the width of the occupant's back at different height positions and provide a better wrapping effect.

[0097] In one embodiment, side wing pressure sensor arrays are respectively arranged on both sides of the side wings. The side wing pressure sensor arrays include a plurality of side wing pressure sensors arranged along the height direction. Controlling the tightness of the side wing wrapping structures at the corresponding heights on both sides of the backrest based on the back width of the occupant at each height further includes:

[0098] During the process of performing tightness adjustment on the side wing wrapping structures at each height, detecting the pressure values of the side wing pressure sensors at each height;

[0099] If the pressure value of the side wing pressure sensor at that height is greater than the pressure threshold, stop the tightness adjustment at that height.

[0100] Specifically, as Figure 3 shown, a flank pressure sensor array 21 is provided on each flank 20, and the flank pressure sensor array 21 includes a plurality of flank pressure sensors 2121 arranged along the height direction. Figure 3 Each red dot on the middle flank 20 is a flank pressure sensor 2121. Each flank pressure sensor 2121 outputs the detected pressure value.

[0101] During the process of adjusting the tightness of each flank wrapping structure and adjusting the flank wrapping to the tightness corresponding to the back width of the occupant at the height position, once the pressure value detected by the flank pressure sensor at this height is greater than the preset pressure threshold, the adjustment is stopped.

[0102] In this embodiment, according to the calculation of the back widths at different heights such as different lumbar vertebrae and thoracic vertebrae, the adjustment of the wrapping tightness of the flank sensors at the corresponding positions is provided. At the same time, a maximum threshold is set. By increasing the detection of the flank pressure sensors, excessive pressure on the occupant is avoided, ensuring the comfort of the occupant.

[0103] As Figure 5 shown is the flowchart of the working process of a vehicle flank adjustment method according to the best embodiment of the present invention, including:

[0104] Step S501, scanning the pressure values of all back pressure sensors;

[0105] Step S502, outputting the pressure value matrix of the back pressure sensors;

[0106] Step S503, using the corresponding positions of the back pressure sensors on the spinal cord line (Y direction) as the origin O1... On of each row of coordinates;

[0107] Step S504, taking O1 as the origin, extracting the pressure values of the corresponding row at this position, respectively identifying the non-zero pressure minimum values to the left and right, and extracting the coordinates B1(X1, Y1), B2(X2, Y2) of the corresponding points;

[0108] Step S505, calculating the back width at this position using the distance formula:

[0109]

[0110] Step S506, calculating the back widths at different Y-direction height positions in the same way in turn, and outputting the width columns L1... Ln

[0111] Step S507, according to the calibration result, adjusting the tightness of the flank sensors at the corresponding positions according to different back widths. Step S508, when the pressure value of the flank pressure sensor at the corresponding position of the flank reaches the threshold, stop.

[0112] In one of the embodiments, the backrest 10 further includes a backrest foam 2, a backrest massage unit 3, and a backrest support structure 4. The back pressure sensor array 1 is fixed on the first surface of the backrest foam 2. The backrest massage unit 3 is fixed on the first surface of the backrest foam 2 and is in the same plane as the back pressure sensor array 1. The backrest support structure 4 is fixed on the second surface of the backrest foam 2.

[0113] As Figure 6 shown, the back pressure sensor array 1 is arranged in the groove on the first surface (A surface) of the backrest foam 2, as close to the human body as possible while reducing the sense of foreign objects.

[0114] In some embodiments, the backrest 10 successively includes: a backrest heating pad 5, a backrest comfort cotton (Slab) 6, a backrest massage unit 3, a backrest foam 2, a backrest ventilation airbag 7, a backrest support structure 4, and a backrest frame 8. Among them, the backrest massage unit 3 is a massage airbag, and the backrest support structure 4 is a support airbag. The back pressure sensor array 1 is juxtaposed with the backrest massage unit 3 and is located between the backrest Slab 6 and the backrest foam 2. The backrest heating pad 5, the backrest Slab 6, the backrest massage unit 3, and the back pressure sensor array 1 are located on the first surface (A surface) of the backrest foam 2, and the backrest ventilation airbag 7, the backrest support structure 4, and the backrest frame 8 are located on the second surface (B surface) of the backrest foam 2.

[0115] Among them, the areas where the pressure sensors are arranged include:

[0116] The intersection areas of the human body trunk line and the seat, such as the intersection areas of the spine line and the backrest, the leg trunk line and the seat cushion, etc.

[0117] The contact areas with the human body during the adjustment of the seat surface, such as the contact areas with the human body during the adjustment of the backrest flank.

[0118] The areas where the interaction force between the human body and the seat changes significantly during the adjustment of the seat, such as the contact area between the human waist and the backrest, and its interaction force changes significantly when adjusting the backrest angle.

[0119] Based on the pressure sensor data on the spine line and the leg trunk line, humans with different heights and body types can be distinguished.

[0120] Based on the pressure sensor data on the spine line, the leg trunk line, and the seat cushion / backrest flank, humans with different fatness and thinness body types can be distinguished.

[0121] At the same time, the pressure sensors cannot overlap with ventilation holes, heating wires, massage airbags, etc. in space.

[0122] On the side where the pressure sensor is pasted to the A surface of the foam, a metal sheet can be pasted corresponding to each sensing point to improve the measurement accuracy and durability performance.

[0123] In one embodiment, the back pressure sensor array 1 sequentially includes, from top to bottom: a first back substrate layer 11, a back sensor layer 12, a second back substrate layer 13, and a back reinforcement sheet layer 14. The back sensor layer 12 includes a plurality of spaced-apart back pressure sensors 121, and a back insulating layer 122 is filled between two adjacent back pressure sensors 121. Each back pressure sensor 121 sequentially includes, from top to bottom, a back upper electrode 1211, a back pressure-sensitive layer 1212, and a back lower electrode 1213.
