DETAILED DESCRIPTION
[0047] The specific embodiments of the present application are further described below with reference to the accompanying drawings. The same reference numbers in different drawings denote the same or similar components. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer" refer to the directions towards or away from the geometric center of a particular component.
[0048] As Figure 1 shown is a work flow chart of a vehicle side wing adjusting method according to an embodiment of the present application, comprising:
[0049] Step S101, obtaining a plurality of pressure values of a back pressure sensor array of a seat of a vehicle arranged on a backrest, the back pressure sensor array comprising a plurality of array-arranged back pressure sensors;
[0050] Step S102, determining a passenger back width based on the pressure values;
[0051] Step S103, controlling the side wings on both sides of the backrest to perform wrapping operation according to the passenger back width.
[0052] Specifically, the present application can be applied to electronic devices with processing capabilities, such as controllers of vehicles. For example, electronic controller units (ECU) of vehicles.
[0053] First, step S101 is executed to obtain multiple pressure values from a back pressure sensor array mounted on the backrest of the vehicle's seat. The back pressure sensor array includes multiple back pressure sensors arranged in an array.
[0054] Specifically, such as Figure 3 As 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 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 performed to determine the occupant's back width based on the pressure value.
[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, which involves controlling the wrapping operation on the side wings of the backrest according to the width of the occupant's back.
[0058] like Figure 3 As shown, side wings 20 are also provided on both sides of the backrest 10. The side wings 20 on both sides wrap around the occupant. The tightness of the side wings 20 wrapping around the occupant is adjusted according to the width of the occupant's back.
[0059] The present invention incorporates a pressure sensor on the backrest of a vehicle seat. By acquiring multiple pressure values from the back pressure sensor array on the backrest, the width of the occupant's back is determined. Based on the width of the occupant's back, the side wings on both sides of the backrest are controlled to provide a wrapping operation, thereby improving seat comfort and user experience.
[0060] like Figure 2 The diagram shown is a flowchart of a vehicle side wing adjustment method according to another embodiment of the present invention, including:
[0061] Step S201: Obtain multiple pressure values from the back pressure sensor array installed on the backrest of the vehicle seat. The back pressure sensor array includes multiple back pressure sensors arranged in an array. The back pressure sensors are arranged in columns extending from the bottom to the top of the backrest and in rows extending from the left side to the right side of the backrest. The array has multiple rows and columns of back pressure sensors. The direction from the bottom to the top of the backrest is the height direction. Multiple side wing wrapping structures are provided on both sides along the height direction.
[0062] Step S202, based on the pressure value, determine the passenger back width of multiple heights in the height direction.
[0063] Step S203, based on the passenger back width of each height, control the tightness of the side wing wrapping structure of the corresponding height of the side wing on both sides of the backrest.
[0064] Specifically, first perform step S201, obtain multiple pressure values of the backrest pressure sensor array of the seat of the vehicle arranged on the backrest.
[0065] As shown in the Figure 3 backrest 10 is provided with a backrest pressure sensor array 1, and the backrest pressure sensor array 1 includes a plurality of backrest pressure sensors 121 arranged in an array. Figure 3 Each red dot in the backrest 10 is a backrest pressure sensor 121. Each backrest pressure sensor 121 outputs a detected pressure value. The backrest pressure sensor 121 can be used to detect the width of the passenger's back.
[0066] The backrest pressure sensors 121 are arranged in rows and columns to form the backrest pressure sensor array 1. Among them, Figure 3 In other words, the y direction in the Figure 3 is the height direction. The x direction in the Figure 3 is the row direction.
[0067] Specifically, the backrest pressure sensors 121 are arranged in rows and columns, including:
[0068] A first vertical line perpendicular to the edge of the backrest bottom and extending from the backrest bottom to the backrest top, the direction parallel to the first vertical line is the column direction, and the second vertical line perpendicular to the first vertical line and extending from the left side of the backrest to the right side of the backrest is the row direction.
[0069] At the same time, the backrest 10 is also provided with side wings 20 on both sides, which wrap the human body through the side wings 20.
[0070] As shown in the Figure 4 , the width of the human back is different, and there are narrow back and wide back. When the passenger's back is in contact with the back surface of the backrest 10, the back surface will be concave. Different back widths have different contact areas with the backrest. The contact length of the narrow back body 41 with the backrest 10 will be smaller than the contact length of the wide back body 42 with the backrest 10. Therefore, by detecting the pressure value of the backrest pressure sensor, it can be determined whether the backrest pressure sensor position is in contact with the passenger's back, so as to determine the passenger's back width.
[0071] Then, step S202 is performed to determine the occupant back width at multiple heights in the height direction based on the pressure values.
[0072] Specifically, the human back has different widths at different height positions. By detecting pressure values at different heights, the occupant back width at the height is determined.
[0073] The height position is a position in the height direction, i.e. Figure 3 a position in the y direction.
[0074] In one embodiment, the determining the occupant back width at multiple heights in the height direction based on the pressure values includes:
[0075] For each row in the back pressure sensor array, the position of the back pressure sensor with the minimum non-zero pressure value on the left side of the row is obtained as the left side exit point, and the position of the back pressure sensor with the minimum non-zero pressure value on the right side of the row is obtained as the right side exit point.
[0076] The distance between the left side exit point and the right side exit point of each row is calculated as the occupant back width at the height of the row.
[0077] Specifically, each row corresponds to a height position. Each row represents the pressure values in the horizontal direction (i.e. Figure 3 X direction) at the height in the different height direction (i.e. Figure 3 Y direction) of the back. In the same row, i.e. at the same height position, the left side exit point is calculated as the minimum non-zero pressure value on the left side, and the right side exit point is calculated as the minimum non-zero pressure value on the right side. The minimum non-zero pressure value is the minimum value among the non-zero pressure values.
[0078] The left side and the right side are distinguished by the backrest center line. The backrest center line is the geometric center line of the backrest, and the backrest is symmetric about the geometric center line of the backrest. The backrest center line is generally a line aligned with the natural curvature of the human spine, i.e. the backrest center line can be considered as the backrest spine line.
[0079] The position of the back pressure sensor with the minimum non-zero pressure value on the left side of each row is obtained as the left side exit point, and the position of the back pressure sensor with the minimum non-zero pressure value on the right side of each row is obtained as the right side exit point. Specifically, the position of the back pressure sensor with the minimum non-zero pressure value on the left side of the backrest center line of each row is obtained as the left side exit point, and the position of the back pressure sensor with the minimum non-zero pressure value on the right side of the backrest center line of each row is obtained as the right side exit point.
[0080] As shown in FIG. Figure 3 The back pressure sensor array 1 has at least one column of back pressure sensors arranged along the backrest center line. The back pressure sensor arranged on the backrest center line can be used as the spine pressure sensor 15.
[0081] In one embodiment, calculating the distance between the left and right departure points of each row as the occupant back width at the height of each row includes:
[0082] A two-dimensional coordinate system is established for the back pressure sensor array, with the center line of the backrest as the first coordinate axis and the straight line parallel to the row of the back pressure sensor array 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 in the two-dimensional coordinate system, and calculate the occupant back width at the height of each row based on the coordinates of the left departure point and the right departure point.
[0084] Specifically, in the direction of height along the center line of the backrest (spine line) Figure 3 The column corresponding to all the back pressure sensors (in the Y direction) is taken as the midpoint of the entire pressure matrix, and this midpoint is used as the zero point of each row's coordinates. That is, the center line of the backrest is taken as the first coordinate axis, such as the y-axis, and the straight line parallel to the rows of the back pressure sensor array is taken as the second coordinate axis, such as the x-axis.
[0085] By obtaining the coordinates of the departure points B1(X1, Y1) and B2(X2, Y2) on the left and right sides of the corresponding row, the back width L at that height can be calculated as follows:
[0086] Since they are in the same row, Y2 and Y1 are the same, and Y2-Y1=0.
[0087] Then, step S203 is performed, based on the occupant back width at each height, controlling the tightness of the side wing wrapping structure at the corresponding height of the side wings on both sides of the backrest.
[0088] Specifically, the side wing wrapping structure includes, but is not limited to, a mechanical wrapping structure or a pneumatic wrapping structure. The mechanical wrapping structure can be a motor-driven support structure. The pneumatic wrapping structure can be an air bag that is inflated or deflated by an air pump.
[0089] For the case where the side wing wrapping structure is mechanically wrapped, the tightness is determined by the stroke of the motor shaft. For the case where the side wing wrapping structure is pneumatically wrapped, the tightness is determined by the air pressure in the air bag.
[0090] In some embodiments, a side wing wrapping structure is provided at the same height position of each backrest pressure sensor.
[0091] The embodiment establishes a coordinate system, detects the back width of the passenger in real time through the coordinate system, and automatically adjusts the tightness of the side wing at different heights according to the detection result, so as to realize accurate wrapping of the passenger's back and improve the riding comfort. The embodiment can update the back width data according to the dynamic changes of the passenger (such as the adjustment of the sitting posture), dynamically adjust the tightness of the side wing sensor at the corresponding position, and ensure the riding comfort.
[0092] In one embodiment, the tightness of the side wing wrapping structure at the corresponding height of the side wing on both sides of the backrest is controlled based on the passenger's back width at each height, including:
[0093] The tightness of the side wing wrapping structure at each height is adjusted by controlling the side wing on both sides of the backrest, and the tightness is adjusted to the tightness corresponding to the passenger's back width at the height.
[0094] Specifically, a back width is detected at each height to form a width column. Each width corresponds to a tightness. The tightness corresponding to different widths can be determined in advance by calibration. Or a plurality of pairs of back width and tightness are set in advance, and the fitting function of tightness and back width is determined by fitting. After detecting the back width at each height by the back pressure sensor, the tightness corresponding to the back width is determined by, for example, looking up the table or substituting the fitting function.
[0095] Then the tightness of the side wing wrapping structure at each height is adjusted to the tightness corresponding to the passenger's back width at the height. For example, the stroke of the motor at each height is controlled to the stroke corresponding to the passenger's back width at the height, or the air pressure of the air bag at each height is controlled to the air pressure corresponding to the passenger's back width at the height.
[0096] The embodiment sets the corresponding tightness for the passenger's back width at each height, so as to more accurately adapt to the width of the passenger's back at different height positions and provide better wrapping effect.
[0097] In one embodiment, the side wing on both sides is respectively provided with a side wing pressure sensor array, the side wing pressure sensor array includes a plurality of side wing pressure sensors arranged along the height direction, and the tightness of the side wing wrapping structure at the corresponding height of the side wing on both sides of the backrest is controlled based on the passenger's back width at each height, further including:
[0098] In the process of adjusting the tightness of the side wing wrapping structure at each height, the pressure value of the side wing pressure sensor at each height is detected.
[0099] If the pressure value of the side wing pressure sensor at the height is greater than the pressure threshold value, the tightness adjustment at the height is stopped.
[0100] Specifically, as shown in Figure 3 Each side wing 20 is provided with a side wing pressure sensor array 21, which includes a plurality of side wing pressure sensors 2121 arranged along the height direction. Figure 3 Each red dot on the middle side wing 20 is a side wing pressure sensor 2121. Each side wing pressure sensor 2121 outputs the detected pressure value.
[0101] In the process of adjusting the tightness of each side wing wrapping structure to the tightness corresponding to the occupant's back width at the height position, once the pressure value detected by the side wing pressure sensor at the height is greater than the preset pressure threshold, the adjustment is stopped.
[0102] The embodiment provides adjustment of the tightness of the corresponding position side wing sensor according to the calculation of the back width at different heights of different lumbar vertebrae, thoracic vertebrae, etc., while setting a maximum threshold, and avoids excessive pressure on the occupant by increasing the detection of the side wing pressure sensor, thereby ensuring the comfort of the occupant.
[0103] As shown in Figure 5 The working flowchart of the vehicle side wing adjustment method of the best embodiment of the present application is shown in the figure, which includes:
[0104] Step S501, scan the pressure values of all back pressure sensors;
[0105] Step S502, output the pressure value matrix of the back pressure sensor;
[0106] Step S503, take the corresponding position of the back pressure sensor in the spine line (Y direction) as the coordinate origin O1…On of each row;
[0107] Step S504, take O1 as the origin, extract the pressure values of the corresponding row at this position, identify the minimum non-zero pressure to the left and right respectively, and extract the coordinates B1(X1, Y1), B2(X2, Y2) of the corresponding points;
[0108] Step S505, calculate the back width at this position using the distance formula:
[0109]
[0110] Step S506, calculate the back width at different Y direction height positions in the same way, and output the width column L1…Ln
[0111] Step S507, adjust the tightness of the corresponding position side wing sensor according to different back widths through the calibration result, and step S508, stop when the pressure value of the side wing pressure sensor at the corresponding position of the side wing reaches the threshold.
