[0063] The specific implementation of the present application is further described below with reference to the accompanying drawings.

Therefore, these or other directional terms should not be interpreted as restrictive terms. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0066] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above-mentioned in this application can be understood according to the specific circumstances.

[0067] The seat adaptive adjustment method in the embodiment of the present application is as follows Figure 1 As shown, the following steps are included:

[0068] Step S101: establishing a calibration plane coordinate system, where the calibration plane coordinate system is located on a seat section plane established based on the vehicle length direction and the vehicle height direction.

[0069] like Figure 2 As shown, the calibration plane coordinate system is set along the length direction and height direction of the vehicle, and the plane where the calibration plane coordinate system is located is the cross-section of the target seat. On this plane, the coordinate origin can be set according to actual needs. In the embodiment of the present application, the center point of the lens of the face acquisition camera is used as the origin, the horizontal coordinate X is set along the length direction of the vehicle, and the vertical coordinate Z is set along the height direction of the vehicle.

[0070] Step S102: Determine the target line equation of the calibration point on the calibration plane coordinate system according to the driver's field of vision requirement, where the calibration point is located at the driver's head.

[0071] Preferably, the driver's eye position is selected as the calibration point. The calibration point target line equation is determined on the calibration plane coordinates according to the driver's field of vision requirements. When the calibration point of the driver's head is on the calibration point target line equation, the driver can be guaranteed to have a better field of vision. Since the positional relationship between the various points on the driver's head is fixed, other position points on the driver's head can also be selected as calibration points, and the corresponding calibration point target line equation can be obtained according to the positional relationship between the calibration point and the eye position point.

[0072] Step S103: determining the sitting posture association data between the calibration point and the seat hard point on the calibration plane coordinate system according to the driver's sitting posture requirement, where the seat hard point is a point on the seat that does not move with the seat adjustment.

[0073] Preferably, the seat hard point is set as the connection point between the seat cushion and the seat back, that is, point P shown in the figure. Specifically, when the driver drives the vehicle, the driver needs to sit in the main driver's seat according to the sitting posture requirements, such as Figure 2 As shown in the figure, the bottom of the driver's thigh fits against the seat cushion, the back is close to the seat back, and the back of the head rests on the headrest surface. When the driver sits on the seat according to the sitting posture requirements, even if the seat is adjusted, some positional relationships between the check point A and the seat hard point P remain unchanged, such as the distance between the check point A and the seat hard point P, and the angle a between the check point seat hard point connection line and the backrest.

[0074] Step S104: Determine the seat hard point target coordinate range and the corresponding seat back angle range according to the riding comfort requirements and the driver's body size data in combination with the calibration point target line equation and the sitting posture association data.

[0075] According to the definition of ergonomic research, there are riding comfort requirements, which include the comfortable angle range between various joints of the human body. If the driver meets the riding comfort requirements, the riding and driving comfort can be guaranteed. According to the riding comfort requirements, the driver's body size data, the check point target line equation obtained in step S102 and step S103, and the sitting posture related data, several equations are obtained, and the seat hard point target coordinate range and the corresponding seat back angle range are obtained by solving the equations. Each seat hard point target coordinate in the seat hard point target coordinate range corresponds to a seat back angle range.

[0076] Step S105: adjusting the seat according to the seat hard point target coordinate range and the seat back angle range.

[0077] First, the seat hard point target coordinates and seat back angle can be determined within the seat hard point target coordinate range and seat back angle range according to user customization requirements or system setting rules. Then, the seat hard point target coordinates and seat back angle are converted into actual seat position and actual seat back angle. Then, the seat adjustment strategy is determined based on the current seat position and back angle, and the seat adjustment strategy is sent to the seat control module for execution.

[0078] The embodiment of the present application establishes a calibration plane coordinate system, determines the calibration point target line equation and the sitting posture correlation data between the calibration point and the seat hard point according to the driver's field of vision requirements and the driver's sitting posture requirements, and then combines the riding comfort requirements and the driver's body size data to determine the seat hard point target coordinate range and the corresponding seat back angle range by solving a group of equations. It can take into account the correlation between the seat part adjustments, and comprehensively consider the requirements of field of vision, riding comfort and safety to obtain the best seat adjustment strategy.

[0079] In one embodiment, the check point is the eye position point, and the check point target line equation is determined on the check plane coordinate system according to the driver's field of vision requirements, specifically including:

[0080] Determine the coordinates of the upper dead point of the field of view, the coordinates of the lower dead point of the field of view, and the ground projection point coordinates of the front end of the vehicle on the calibration plane coordinate system;

[0081] Taking the ground projection point coordinates of the front end of the vehicle as a reference, determine the upper field of view requirement point coordinates and the lower field of view requirement point coordinates according to the driver's field of view requirements;

[0082] Determine the upper field of view line equation according to the upper dead point coordinates of the field of view and the upper field of view required point coordinates, and determine the lower field of view line equation according to the lower dead point coordinates of the field of view and the lower field of view required point coordinates;

[0083] The target line equation of the verification point is determined based on the upper field of view equation and the lower field of view equation.

[0084] like Figure 3 As shown, the driver's field of vision is limited by the upper and lower edges of the front windshield. To calculate the boundary line equation of the driver's field of vision, the coordinates of the upper dead point of the field of vision W are obtained. up1 and the lower dead center of vision W down1 Coordinates, and at the same time obtain the coordinates of the ground projection point W0 at the front of the vehicle for subsequent determination of the upper field of view required point W up2 Coordinates and bottom vision require point W down2 The ground projection point of the front end of the vehicle is the intersection of a vertical line drawn through the front end point of the protruding part of the front anti-collision beam and the ground.

[0085] According to the national standard, the driver's vision verification requirements stipulate the upper vision requirement points and the verification method of the upper vision requirement points in the cab, as well as the lower vision requirement points and the verification method of the lower vision requirement points. Based on the above requirements and verification methods, the ground projection point W0 coordinates (X exteriorview , Z exteriorview ), height H of upper field of view target point up_visual , distance D from upper field of view target point up_visual , distance D from lower field of view target point down_visual , determine the upper field of view requirement point W up2 The coordinates are (X exteriorview -D up_visual , Z exteriorview +H up_visual ), the lower vision requires point W down2 Coordinate (X exteriorview -D down_visual , Z exteriorview ).

[0086] After that, the upper field of view equation can be determined according to the coordinates of the upper dead point of the field of view and the coordinates of the upper field of view requirement point. Similarly, the lower field of view equation can be determined according to the coordinates of the lower dead point of the field of view and the coordinates of the lower field of view requirement point. When the driver's eyes are located between the upper field of view equation and the lower field of view equation, the driver's field of view requirements of the national standard can be met. In order to ensure that the driver's upper and lower viewing angles are balanced, and because the driver will move during driving, the angle bisector between the upper field of view line and the lower field of view line can be selected as the calibration point target line L eye , the equation of the target line of the check point can be obtained according to the equation of the upper field of view line and the equation of the lower field of view line.

[0087] It should be noted that for some vehicles with higher hoods, the driver's field of vision may be limited by the upper edge of the front windshield and the highest point of the hood. Therefore, the coordinates of the lower dead point of the field of vision in the embodiment of the present application can be replaced with the coordinates of the highest point of the hood according to the vehicle structure.

[0088] In one embodiment, the sitting posture-related data includes the length of the check point and the hard point of the seat;

[0089] Determining the sitting posture association data between the verification point and the seat hard point on the verification plane coordinate system according to the driver's sitting posture requirement specifically includes:

[0090] Determine the current calibration point coordinates and the current seat hard point coordinates on the calibration plane coordinate system;

[0091] The length between the check point and the seat hard point is determined according to the current check point coordinates and the current seat hard point coordinates.

[0092] like Figure 2As shown in the figure, when the driver sits on the seat according to the sitting posture requirements, even if the front and back position of the seat and the backrest angle are adjusted, the length of the check point A and the seat hard point P remains unchanged. To this end, the current check point coordinates and the current seat hard point coordinates are determined on the check plane coordinate system, where the current check point coordinates can be determined by the image collected by the face recognition camera, and the current seat hard point coordinates can be obtained by obtaining the current seat position state, combining the current seat state and seat size information. For two known coordinate points, the check point and the seat hard point length can be directly calculated through the coordinate points.

[0093] In one embodiment, the sitting posture-related data further includes an angle between a connection line of the hard points of the check point seat and a backrest;

[0094] The method further comprises: determining the sitting posture association data between the checking point and the seat hard point on the checking plane coordinate system according to the driver's sitting posture requirement;

[0095] Get the current seat back angle;

[0096] The angle between the check point seat hard point connection line and the backrest is determined based on the current check point coordinates, the current seat hard point coordinates and the current seat backrest angle.

[0097] like Figure 2 As shown, when the driver sits on the seat according to the sitting posture requirements, as the seat position and the backrest angle are adjusted, since the relative position between the driver and the seat does not change, the angle a between the check point seat hard point connection line and the backrest remains unchanged.

[0098] The embodiment of the present application obtains the current seat back angle b from the seat control module, and calculates the slope of the seat hard point line of the current verification point according to the current verification point coordinates and the current seat hard point coordinates, and calculates the angle c between the seat hard point line of the current verification point and the horizontal coordinate line according to the trigonometric function relationship, and the angle a between the seat hard point line of the verification point and the backrest is obtained by subtracting the current seat back angle b from the angle c.

[0099] In one embodiment, determining the coordinates of the current calibration point on the calibration plane coordinate system specifically includes:

[0100] Determine the current seat back vertex coordinates on the calibration plane coordinate system;

[0101] Determine the abscissa of the current calibration point according to the abscissa of the current seat back vertex coordinate and the current estimated head length;

[0102] Obtain the installation parameters of the face recognition camera and the imaging height of the current calibration point in the imaging area of ​​the face recognition camera;

[0103] The vertical coordinate of the current calibration point is determined according to the installation parameters of the face recognition camera, the imaging height of the calibration point and the horizontal coordinate of the calibration point.

[0104] In the embodiment of the present application, the coordinates of the current verification point are determined by a face recognition camera. For a face recognition camera that does not have a ranging function, the coordinates of the current verification point are determined by combining the imaging image of the face recognition camera and the camera installation parameters.

[0105] like Figure 4 As shown, the current seat position information is obtained from the seat control module, and the current seat back vertex Q coordinate is determined in combination with the seat size information. Then, the horizontal coordinate of the current seat back vertex is added to the current estimated head length L head It is the horizontal coordinate of the current calibration point. The current estimated head length L head It can be determined based on the dimensions of various parts of an adult in ergonomics, for example, by selecting the median of the head length dimension data.

[0106] Then, based on the approximate triangle relationship of the face recognition camera imaging, the vertical coordinate of the current calibration point is determined according to the face recognition camera installation parameters, the imaging height of the calibration point and the horizontal coordinate of the calibration point.

[0107] like Figure 4 As shown, straight line CB is the center line of the camera, line segment CD is the imaging height of the verification point, and line segment OC is the focal length of the camera. The angle of ∠COD can be calculated. The angle of ∠OAB is equal to the angle of ∠COD. ∠COD plus the camera elevation angle e is the angle between the straight line OA and the horizontal coordinate. The vertical coordinate of the verification point can be determined according to the horizontal coordinate of the verification point and the angle between the straight line OA and the horizontal coordinate based on trigonometric functions.

[0108] Further, determining the coordinates of the current calibration point on the calibration plane coordinate system also includes:

[0109] Get the imaging height of the current first reference point in the imaging area of ​​the face recognition camera, where the first reference point is the head position point on the same vertical line as the verification point, and the horizontal coordinate of the current verification point is used as the horizontal coordinate of the current first reference point;

[0110] Determine the current first reference point vertical coordinate according to the face recognition camera installation parameters, the reference point imaging height and the current first reference point horizontal coordinate;

[0111] Determine the driver's height based on the current first reference point ordinate, the current check point ordinate and the standard relationship of human body size;

[0112] Determine the latest estimated head length based on the standard relationship between the driver's height and human body dimensions;

[0113] If the difference between the latest estimated head length and the current estimated head length is greater than the preset difference, the latest estimated head length is used as the current estimated head length, and the step of determining the horizontal coordinate of the verification point according to the horizontal coordinate of the current seat back vertex coordinate and the current estimated head length is returned.

[0114] Since the current estimated head length used to determine the horizontal coordinate of the current verification point in the embodiment of the present application is an estimated value and deviates from the actual value, in order to correct the current estimated head length to improve the accuracy of the coordinates of the current verification point, a first reference point E can be marked on the driver's head. For ease of calculation, the first reference point is selected as a position point on the same vertical line as the verification point. As an example, the first reference point can be selected as the chin position point.

[0115] Since the first reference point and the check point are located on the same vertical line, the current check point abscissa is the current first reference point abscissa. Then, the current first reference point abscissa can be calculated based on the principle of similar triangles by combining the camera installation height, installation angle and focal length information in the same way as determining the current check point ordinate. The length between the current check point and the current first reference point can be calculated based on the current check point coordinates and the current first reference point coordinates, and the length value is the face length data. According to the correspondence between the face length data and the height in the "Chinese Adult Body Size Standard", the driver's height can be determined, and then the corresponding latest estimated head length can be determined based on the driver's height. If the difference between the latest estimated head length and the current estimated head length is greater than the preset difference, the current estimated head length is considered to be more reasonable, otherwise the latest estimated head length is used as the current estimated head length, and the step of determining the check point abscissa based on the abscissa of the current seat back vertex coordinates and the current estimated head length is returned to correct the estimated head length.

[0116] In one embodiment, determining the coordinates of the current calibration point on the calibration plane coordinate system specifically includes:

[0117] Obtain the straight-line distance between the calibration point and the face recognition camera, and the inclination angle of the calibration point between the straight line between the calibration point and the center point of the camera and the center line of the face recognition camera;

[0118] The coordinates of the current calibration point are determined according to the installation parameters of the face recognition camera, the straight-line distance of the calibration point and the inclination of the calibration point.

[0119] The embodiment of the present application determines the coordinates of the current verification point based on a face recognition camera with a distance measurement function, such as Figure 6 As shown, the face recognition camera can directly obtain the straight-line distance OA of the verification point and the inclination angle d of the verification point, and combine the camera elevation angle e to determine the horizontal and vertical coordinates of the current verification point coordinates according to trigonometric functions.

[0120] In one embodiment, the sitting posture-related data includes the length between the check point and the seat hard point and the angle between the check point and the seat hard point and the backrest;

[0121] According to the riding comfort requirements and the driver's body size data, combined with the calibration point target line equation and the sitting posture association data, the seat hard point target coordinate range and the corresponding seat back angle range are determined, including:

[0122] Determine the coordinates of the driver's ankle point and the equation of the straight line on the calibration plane coordinate system;

[0123] Determine the driver's knee point coordinate set based on the driver's ankle point coordinates, the sole straight line equation, the driver's calf length, and the comfortable range of the angle between the sole line and the calf line;

[0125] Determine the seat hard point coordinate set according to the driver's hip point coordinate set and the driver's thigh thickness;

[0126] According to the seat hard point coordinate set, the comfortable range of the angle between the thigh line and the body, the target line equation of the check point, the length between the check point and the seat hard point, and the angle between the check point seat hard point connection line and the backrest, the seat hard point target coordinate range and the corresponding seat back angle range are determined. Each seat hard point target coordinate in the seat hard point target coordinate range corresponds to a seat back angle range.

[0127] The embodiment of the present application starts the comfort check from the driver's foot. First, the coordinates of the driver's ankle point and the equation of the sole of the foot are determined based on the pedal position. Then, the driver's knee point coordinate set is calculated based on the driver's calf length and the comfortable range of the angle between the foot line and the calf line in the riding comfort requirement. Then, the driver's hip point coordinate set is determined according to the driver's knee point coordinate set, the driver's thigh length and the comfortable range of the angle between the calf line and the thigh line in the riding comfort requirement. The seat hard point coordinate set can be determined according to the driver's hip point coordinate set and the driver's thigh thickness. The seat hard point coordinate set is combined with the comfortable range of the angle between the thigh line and the body, and the target line equation of the check point determined in the above steps, the length of the check point and the seat hard point, and the angle between the check point and the seat hard point connection line and the backrest, to obtain several relationship equations about the seat hard point, and the seat hard point target coordinate range and the seat back angle range are determined by solving the equation group. This seat adjustment method not only takes into account the driver's field of vision requirements and riding comfort, but also takes into account the correlation between the position adjustment of each part of the seat, so that the seat can be more intelligently adjusted adaptively.

[0128] Among them, the driver's body dimension data of the driver's calf length, the driver's thigh length and the driver's thigh thickness can be guided by the user to actively input, and can also be determined through image recognition and other methods.

[0129] like Figure 6 As shown, the steps of determining the coordinates of the driver's ankle point and the equation of the sole straight line specifically include:

[0130] Set the equation of the straight line at the bottom of the foot to Z = K foot ×X+B foot ;

[0131] The coordinates of the heel point F, the pedal protruding point G and the ankle mapping point I all satisfy the sole straight line equation, where the heel point F is on the floor line. The ordinate of the heel point F can be determined according to the vehicle size data, and three sole relationship equations can be obtained;

[0132] To obtain the driver's foot length, we can roughly assume that the ratio of the distance from the pedal protrusion point G to the heel point F to the driver's foot length is K. G-F , it is approximately assumed that the distance from the ankle mapping point I to the heel point F and the calculated ratio of the driver's foot length are K I-F , we can get two foot-sole relationship equations;

[0133] Based on the above five sole relationship equations, the coordinates of ankle mapping point I and the sole straight line equation can be solved.

[0134] Draw an ankle straight line L through ankle point J parallel to the straight line of the sole of the foot ankle , set the ankle straight line equation to Z = K ankle ×X+B ankle , where K ankle =K foot ;

[0135] The J coordinate of the ankle point satisfies the ankle straight line equation, and an ankle relationship equation is obtained;

[0136] Get the driver's ankle height, based on the straight line between the sole and the ankle L ankle The distance between is the driver's ankle height, and the distance from ankle point J to ankle mapping point I is the driver's ankle height, and two ankle relationship equations are obtained;

[0137] Based on the above three ankle relationship equations, the coordinates of the ankle point can be solved.

[0139] Set the equation of the calf straight line to Z = K calf ×X+Bcalf ;

[0140] The coordinates of the knee point and the ankle point satisfy the straight line equation of the calf, and the relationship equations of the two calves are obtained;

[0141] The angle between the sole straight line and the calf straight line satisfies the comfortable range of the angle between the sole line and the calf line, and a calf relationship equation is obtained;

[0142] The distance between the knee point K and the ankle point J is the driver's calf length, and a calf relationship equation is obtained;

[0143] According to the above four calf relationship equations, the calf straight line equation and the coordinate set of the driver's knee point can be solved.

[0144] The step of determining the driver's hip point coordinate set according to the driver's knee point coordinate set, the driver's thigh length, and the comfortable range of the angle between the calf line and the thigh line specifically includes:

[0145] Set the equation of the thigh straight line to Z = K thigh ×X+B thigh ;

[0146] The coordinates of the knee point and the hip point satisfy the straight line equation of the thigh, and the relationship equation of the two thighs is obtained;

[0147] The angle between the calf line and the thigh line satisfies the comfortable range of the angle between the calf line and the thigh line, and a thigh relationship equation is obtained;

[0148] The distance between the knee point K and the hip point H is the driver's thigh length, and a thigh relationship equation is obtained;

[0149] According to the above four thigh relationship equations, the thigh straight line equation and the driver's hip point coordinate set can be solved.

[0150] Furthermore, since the range of the driver's hip point coordinates is limited by the fore-and-aft adjustment range of the seat, the allowable range of the driver's hip point coordinates can be determined based on the fore-and-aft adjustment range of the seat, and coordinate points in the driver's hip point coordinate set that are not within the allowable range can be removed.

[0151] The steps of determining the seat hard point coordinate set according to the driver's hip point coordinate set and the driver's thigh thickness are specifically as follows:

[0152] Subtract the driver's thigh thickness and the abscissa calculation coefficient K from the abscissa and ordinate of each driver's hip point coordinate in the driver's hip point coordinate set. thigh-abscissa and the ordinate calculation coefficient K thigh-ordinate The product of can get the seat hard point coordinate set.

[0153] The steps of determining the target coordinate range of the seat hard point and the corresponding seat back angle range according to the seat hard point coordinate set, the comfortable range of the thigh line and the body angle, the check point target line equation, the check point and the seat hard point length, and the angle between the check point seat hard point connection line and the backrest include:

[0154] Set the target coordinates of the calibration point, the target coordinates of the seat hard point and the target angle of the seat back;

[0155] The target coordinates of the check point satisfy the target line equation of the check point, and the target coordinates of the seat hard point satisfy the seat hard point coordinate set, and two check relationship equations are obtained;

[0156] The distance between the target coordinates of the check point and the target coordinates of the seat hard point is the length between the check point and the seat hard point, and a check relationship equation is obtained;

[0157] The angle between the line connecting the target coordinates of the check point and the target coordinates of the seat hard point and the backrest is equal to the angle between the line connecting the hard points of the check point and the backrest, and a check relationship equation is obtained;

[0158] The angle between the thigh and the body can be simplified to the angle between the thigh and the seat back. The angle between the thigh and the seat back satisfies the comfortable range of the angle between the thigh line and the body, and a calibration relationship equation is obtained.

[0159] According to the above five verification relationship equations, the target coordinate range of the seat hard point and the corresponding seat back angle range can be solved.

[0160] In the embodiment of the present application, after solving the target coordinate range of the seat hard point and the corresponding seat back angle range, it is necessary to convert the relationship between the calibration plane coordinate system and the actual coordinate system of the vehicle to obtain the upper and lower position range, front and rear position range and back angle range of the seat. Then, the upper and lower target positions, front and rear target positions and back angles are determined according to the user's preset requirements or preset rules. For example, a set of data with the highest upper and lower positions can be selected, or a set of data with the rearmost front and rear positions can be selected.

[0161] In one embodiment, the seat hard point target coordinate range and the corresponding seat back angle range are determined according to the riding comfort requirements and the driver's body size data in combination with the calibration point target line equation and the sitting posture association data, and further includes:

[0162] Determine the coordinates of the current verification point and the coordinates of the current second reference point on the verification plane coordinate system, wherein the second reference point is located at the driver's head and does not coincide with the verification point;

[0163] Determine the driver's height based on the current check point coordinates, the current second reference point ordinate coordinates and the standard relationship of human body dimensions;

[0164] The driver's body size data including at least the driver's calf length, the driver's thigh length and the driver's thigh thickness are determined according to the standard relationship between the driver's height and the body size.

[0165] The driver's body size data in the embodiment of the present application is determined based on the face length data collected by the face recognition camera combined with the standard relationship of body size, and there is no need for the user to actively input the size data, so as to improve the driver's user experience.

[0166] Specifically, the second reference point can be the first reference point E in the aforementioned embodiment, and the method for obtaining the coordinates of the second reference point can refer to the aforementioned embodiment, which will not be repeated here. Similarly, the length between the current check point and the current second reference point can be calculated based on the current check point coordinates and the current second reference point coordinates, and the length value is the face length data. According to the correspondence between the face length data and the height in the "Chinese Adult Body Size Standard", the driver's height can be determined, and then the corresponding driver's calf length, driver's thigh length, driver's thigh thickness and other driver's body size data can be determined based on the driver's height.
