[0031] Embodiment 1

[0032] Figure 1 Flow chart of a method for determining tailgate height provided in an embodiment of the present invention. This embodiment is applicable to the case of determining tailgate height. The method can be executed by a device for determining tailgate height in an embodiment of the present invention. The device can be implemented in software and / or hardware. Figure 1 As shown, the method specifically comprises the following steps:

[0033] S110: If a tailgate opening signal is received and the tailgate user is a target user, memory seat information corresponding to the target user is obtained.

[0034] Among them, the target user can be: a user sitting in the main driving seat, a user sitting in the co-pilot seat, or a user sitting in the back seat, and the embodiment of the present invention does not limit this. It should be noted that if the target user is a user sitting in the main driving seat, the collected memory seat information corresponding to the target user is more comprehensive than that of other users. For example, if the target user is a user sitting in the main driving seat, the memory seat information includes: a first distance between the target point of the seat and the front point of the seat, a second distance between the knee joint of the target user and the front point of the seat, seat height, horizontal distance from the front end of the seat to the pedal, seat belt use length, seat belt use angle, seat tilt angle, and at least one of the horizontal distance between the seat back and the steering wheel.

[0035] The tailgate opening signal may be obtained by: if the tailgate side switch is triggered, the tailgate opening signal is received. It should be noted that the tailgate side switch may be triggered by: the user pressing the tailgate side switch, or by the user setting a gesture or a target voice to trigger the tailgate side switch, which is not limited in the embodiment of the present invention.

[0036] The memory seat information is the seat information collected when the target user is most recently seated. For example, the memory seat information is the seat information collected when the target user is sitting on the seat before using the tailgate.

[0037] It should be noted that the method for determining whether the tailgate user is the target user may be: if the first seat pressure change value is greater than a set threshold, the tailgate user is determined to be the target user, wherein the target user is the user who sat on the first seat most recently; and the memory seat information of the first seat where the target user sat is obtained. The method for determining whether the tailgate user is the target user may also be: if the door closing signal is not received within a preset time after the door opening signal is received, and the first seat pressure change value is greater than a set threshold, the tailgate user is determined to be the target user. The method for determining whether the tailgate user is the target user may also be: if the door closing signal is received within a preset time after the door opening signal is received, the tailgate user is determined to be the target user. The method for determining whether the tailgate user is the target user may also be: if the door closing signal is received within a preset time after the door opening signal is received, and there is no one in the main driving position, the tailgate user is determined to be the driver. The embodiment of the present invention does not limit this.

[0038] S120: Determine a target height of a target user according to the memory seat information.

[0039] Specifically, the target height of the target user can be determined according to the memory seat information by: determining the target height of the target user according to the seat position information, the seat belt usage information and the seat tilt angle. The target height of the target user can also be determined according to the memory seat information by: determining the target height of the target user according to the first distance between the target point of the seat and the front point of the seat, the second distance between the knee joint of the target user and the front point of the seat, the seat height, the horizontal distance between the front point of the seat and the edge point of the pedal, the seat belt usage length and the seat belt usage angle. The target height of the target user can also be determined according to the memory seat information by: determining the target height of the target user according to the first distance between the target point of the seat and the front point of the seat, the second distance between the knee joint of the target user and the front point of the seat, the seat height, the horizontal distance between the front point of the seat and the edge point of the pedal, the seat belt usage length, the horizontal distance between the seat back and the steering wheel and the seat belt usage angle. The embodiment of the present invention does not limit this. Wherein, the target height is the height of the hand when the target user stands and stretches his arms.

[0040] Optionally, the memory seat information includes: seat position information, seat belt usage information and seat tilt angle;

[0041] Determining a target height of a target user according to the memory seat information includes:

[0042] A target height of a target user is determined according to the seat position information, the seat belt usage information, and the seat tilt angle.

[0043] Among them, the seat position information includes: seat height, horizontal distance between the front end point of the seat and the edge point of the pedal, a first distance between the target point of the seat and the front end point of the seat, a second distance between the knee joint of the target user and the front end point of the seat, and at least one of the horizontal distance between the seat back and the steering wheel.

[0044] Wherein, the seat belt usage information includes: seat belt usage length and / or seat belt usage angle.

[0045] Specifically, the method for determining the target height of the target user based on the seat position information, the seat belt usage information and the seat inclination angle can be: determining the distance between the knee joint and the heel point of the target user based on the seat position information, determining the distance between the target point of the seat and the shoulder position of the target user based on the seat belt usage information and the seat inclination angle, and determining the target height of the target user based on the seat position information, the distance between the knee joint and the heel point of the target user, and the distance between the target point of the seat and the shoulder position of the target user.

[0046] Optionally, the seat position information includes: seat height and a horizontal distance between a front point of the seat and an edge point of a pedal, and the seat belt usage information includes: seat belt usage length and seat belt usage angle;

[0047] Determining a target height of a target user according to the seat position information, the seat belt usage information, and the seat tilt angle includes:

[0048] Acquire a first distance between a target point of the seat and a front end point of the seat, and a second distance between a knee joint of a target user and a front end point of the seat;

[0049] Determine a third distance between the knee joint and the heel point of the target user according to the seat height, the horizontal distance from the front end of the seat to the pedal, the second distance, and the first formula;

[0050] determining a fourth distance between a target point of the seat and a shoulder position of a target user according to the seat belt usage length, the seat belt usage angle, and the seat tilt angle;

[0051] A target height of the target user is determined according to the first distance, the second distance, the third distance, the fourth distance, and the arm length of the target user.

[0052] The arm length of the target user can be obtained by capturing an image of the target user through a camera inside the cockpit, and recognizing the image of the target user. The arm length of the target user can also be determined by the ratio of the forearm length to the upper arm length, the horizontal distance between the seat back and the steering wheel, the seat belt use length, and the seat belt use angle. The embodiment of the present invention is not limited to this.

[0053] Among them, the target point of the seat is a reference point that can more accurately determine the position of the user (driver or passenger) in the seat. This reference point is the rotation point (hip point) where the torso and thigh are connected. The position of the "hip point" measured on the actual vehicle is called the H point. After the user sits down, most of the body weight acts on the seat cushion through the buttocks, a part is borne by the backrest through the back, and a small part acts on the steering wheel and the floor through the left and right hands and feet. In this sitting posture, the movement of the upper part of the user's body must rotate around the horizontal axis of the H point when operating. Therefore, the position of the H point determines the interior size benchmark for user convenience and comfortable riding.

[0054] Among them, the first distance between the target point of the seat and the front end point of the seat can be obtained by: presetting the first distance between the target point of the seat and the front end point of the seat. The first distance between the target point of the seat and the front end point of the seat can also be obtained by: sending a request for obtaining the target point position information to the server according to the identification information of the current vehicle, so that the server queries and obtains the target point position information corresponding to the identification information of the current vehicle, receives the target point position information sent by the server, and determines the first distance between the target point of the seat and the front end point of the seat according to the target point position information. The first distance between the target point of the seat and the front end point of the seat can also be obtained by: sending a request for obtaining the first distance between the target point of the seat and the front end point of the seat according to the identification information of the current vehicle, so that the server queries and obtains the first distance between the target point of the seat and the front end point of the seat corresponding to the identification information of the current vehicle, and receives the first distance between the target point of the seat and the front end point of the seat sent by the server. The embodiment of the present invention does not limit this.

[0055] The method for obtaining the second distance between the knee joint of the target user and the front end point of the seat may be: presetting the second distance between the knee joint of the target user and the front end point of the seat. The method for obtaining the second distance between the knee joint of the target user and the front end point of the seat may also be: sending a request to the server to obtain the second distance between the knee joint of the target user corresponding to the current vehicle and the front end point of the seat. It should be noted that the method for obtaining the second distance between the knee joint of the target user and the front end point of the seat is similar to the method for obtaining the first distance between the target point of the seat and the front end point of the seat, which will not be repeated here.

[0056] Specifically, the method for determining the third distance between the knee joint and the heel point of the target user based on the seat height, the horizontal distance from the front end of the seat to the pedal, the second distance and the first formula can be: substituting the seat height, the horizontal distance from the front end of the seat to the pedal and the second distance into the first formula to obtain the third distance between the knee joint and the heel point of the target user.

[0057] Specifically, the fourth distance between the target point of the seat and the shoulder position of the target user may be determined according to the seat belt usage length, the seat belt usage angle, and the seat tilt angle as follows:

[0058] Specifically, the target height of the target user may be determined according to the first distance, the second distance, the third distance, the fourth distance, and the arm length of the target user by determining the sum of the first distance, the second distance, the third distance, the fourth distance, and the arm length of the target user as the target height of the target user. The target height of the target user may also be determined according to the first distance, the second distance, the third distance, the fourth distance, and the arm length of the target user by determining the arm length of the target user according to the ratio of the forearm length to the upper arm length, the horizontal distance between the seat back and the steering wheel, the seat belt usage length, and the seat belt usage angle, and the target height of the target user may be determined according to the first distance, the second distance, the third distance, the fourth distance, and the arm length of the target user.

[0059] It should be noted that the arm length of the target user may be determined according to the ratio of the forearm length to the upper arm length, the horizontal distance between the seat back and the steering wheel, the seat belt use length, and the seat belt use angle as follows:

[0060] Determine the vertical distance from the target user's shoulder to the seat based on the seat belt length and seat belt angle;

[0061] The target user's arm length is determined based on the ratio of the forearm length to the upper arm length, the horizontal distance between the seat back and the steering wheel, and the vertical distance from the target user's shoulder position to the seat.

[0062] In a specific example, Figure 2 As shown, L1 is the horizontal distance between the seat back and the steering wheel. Since the spatial layout of the cab is fixed, the horizontal distance between the seat back and the steering wheel can be determined. L3 is the height difference between the user's shoulder position and the center position of the steering wheel. Since the center position of the steering wheel is determined, the height difference between the user's shoulder position and the center position of the steering wheel can be determined based on the shoulder position and the center position of the steering wheel. The ratio of the upper arm length to the lower arm length is 5:4, and the angle of the driver's elbow joint is 90°. The arm length of the target user is determined based on the following formula:

[0063]

[0064] Where k is the target user's arm length, x is the target user's upper arm length, and L2 is the straight-line distance between the user's shoulder position and the center of the steering wheel.

[0065] Optionally, the first formula is:

[0066]

[0067] Wherein, K1 is the third distance between the knee joint and the heel point of the target user, H1 is the seat height, L is the horizontal distance from the front end of the seat to the pedal, and ΔX is the second distance between the knee joint of the target user and the front end point of the seat.

[0068] Optionally, determining a fourth distance between a target point of the seat and a shoulder position of a target user according to the seat belt usage length, the seat belt usage angle, and the seat tilt angle includes:

[0069] Determining a vertical distance from a target user's shoulder position to a seat according to the seat belt use length and the seat belt use angle;

[0070] The fourth distance between the target point of the seat and the shoulder position of the target user is determined according to the vertical distance from the shoulder position of the target user to the seat, the seat tilt angle, and a second formula, wherein the second formula is:

[0071]

[0072] Among them, H2 is the vertical distance from the target user's shoulder position to the seat, and ɑ is the seat tilt angle.

[0073] Specifically, the method for determining the vertical distance from the target user's shoulder position to the seat based on the seat belt usage length and the seat belt usage angle can be: pre-establishing a correspondence table between the seat belt usage length and the seat belt usage angle, and the vertical distance from the target user's shoulder position to the seat, and by querying the correspondence table, obtaining the seat belt usage length and the seat belt usage angle, and the vertical distance from the target user's shoulder position to the seat corresponding to the seat belt usage length and the seat belt usage angle.

[0074] S130: If the difference between the target height and the preset height is greater than a difference threshold, determining a tailgate height according to the target height.

[0075] The preset height may be an existing height. The difference threshold may be a preset value, for example, the difference threshold may be 3 centimeters.

[0076] Specifically, if the difference between the target height and the preset height is greater than the difference threshold, the method for determining the tailgate height according to the target height can be: pre-establishing a correspondence table between the height of the hand and the tailgate height when the user stands with his arms straight; if the difference between the target height and the preset height is greater than the difference threshold, querying the correspondence table to obtain the tailgate height corresponding to the target height.

[0077] Optionally, also include:

[0078] If the difference between the target height and the preset height is less than or equal to the difference threshold, the tailgate height corresponding to the pre-stored preset height is queried, and the tailgate height corresponding to the preset height is determined as the final tailgate height.

[0079] In a specific example, the tailgate heights corresponding to the heights in the height set can be pre-stored. If the height set includes multiple preset heights, and there is a preset height whose difference with the target height is less than or equal to a difference threshold, the tailgate height corresponding to the preset height is determined as the final tailgate height. If the differences between the target height and all the preset heights in the pre-stored height set are greater than the difference threshold, the tailgate height is determined according to the target height.

[0080] Optionally, after determining the tailgate height according to the target height, the method further includes:

[0081] Determine the height of the lower edge of the target vehicle tailgate according to the target height;

[0082] Control the vehicle tailgate to lift up to the target height of the lower edge of the vehicle tailgate.

[0083] Optionally, if a tailgate opening signal is received and the tailgate user is a target user, memory seat information corresponding to the target user is obtained, including:

[0084] If the tailgate opening signal is received, the current position is obtained;

[0085] If the current position is not a preset position and the tailgate user is a target user, the memory seat information corresponding to the target user is obtained.

[0086] Specifically, the current location may be acquired by collecting the current location through a positioning device.

[0087] The preset position may be a garage or other low area, which is not limited in the embodiment of the present invention. In a specific example, if a tailgate opening signal is received, the current position is obtained; if the current position is not the preset position, the tailgate is opened to a default height or a maximum height; if the door is closed after the preset time, and someone is sitting in the main driving seat, the height of the tailgate is kept unchanged; if no one is sitting in the main driving seat, the tailgate user is determined to be a target user, and the memory seat information corresponding to the target user is obtained.

[0088] Optionally, also include:

[0089] If the current position is a preset position, the first height is determined as the tailgate height.

[0090] Wherein, the first height is a preset lower height. The first height is smaller than the preset height.

[0091] In the embodiment of the present invention, after receiving the tailgate opening signal, it is determined whether the current position is the preset position, and if the current position is the preset position, the height of the tailgate is set to a lower first height. This prevents the situation where the tailgate is easily hit due to the low environment if the tailgate height is high. The tailgate can be adjusted to a height suitable for the environment.

[0092] Optionally, if the current position is not a preset position and the tailgate user is a target user, the memory seat information corresponding to the target user is obtained, including:

[0093] If the current position is not a preset position, a door opening signal is received, and the first seat pressure change value is greater than a set threshold, the tailgate user is determined to be a target user, wherein the target user is the user who sat in the first seat most recently;

[0094] Obtain the memory seat information of the first seat occupied by the target user.

[0095] The target user may be a user sitting in the main driver's seat, a user sitting in the front passenger seat, or a user sitting in the back seat, and this embodiment of the present invention does not limit this.

[0096] It should be noted that if the current position is not a preset position, a door opening signal is received, and the first seat pressure change value is greater than a set threshold, it is determined that the tailgate user is the user who sat in the first seat most recently.

[0097] In the embodiment of the present invention, the memory seat information corresponding to the target user is the memory seat information of the first seat.

[0098] Optionally, if the current position is not a preset position, a door opening signal is received, and the first seat pressure change value is greater than a set threshold, then determining that the tailgate user is the target user includes:

[0099] If the current position is not a preset position, after receiving the door opening signal, no door closing signal is received within a preset time, and the first seat pressure change value is greater than a set threshold, the tailgate user is determined to be the target user.

[0100] The target user is the user who sat in the first seat most recently.

[0101] The set threshold is a pre-set pressure value. It should be noted that if the pressure change value of the first seat is greater than the set threshold, it means that the user gets off the vehicle and uses the tailgate after sitting in the first seat.

[0102] Optionally, if the current position is not a preset position and the tailgate user is a target user, the memory seat information corresponding to the target user is obtained, including:

[0103] If the current position is not a preset position, and after receiving a door opening signal, a door closing signal is received within a preset time, the tailgate user is determined to be the target user;

[0104] Get the memory seat information corresponding to the target user.

[0105] The target user may be a user sitting in the main driver's seat or a user sitting in the co-pilot's seat, and this embodiment of the present invention does not impose any limitation on this.

[0106] Specifically, if the door corresponding to the door opening signal and the door corresponding to the door closing signal are both the main driver's side door, the target user is the user sitting in the main driver's seat. If the door corresponding to the door opening signal and the door corresponding to the door closing signal are both the co-pilot side door, the target user is the user sitting in the co-pilot seat. In a specific example, if the current position is not a preset position, after receiving the door opening signal, the door closing signal is received within a preset time, and no one is sitting in the main driver's seat, the tailgate user is determined to be the user sitting in the main driver's seat; if the current position is not a preset position, after receiving the door opening signal, the door closing signal is received within a preset time, and someone is sitting in the main driver's seat, the tailgate height is kept unchanged.

[0107] In another specific example, Figure 3 As shown, the tailgate height adjustment strategy includes the following processes:

[0108] Turn on the tailgate side switch and go to step 1. Step 1: Get the current position.

[0109] Step 2: Determine whether the current position is the preset position. If so, execute step 3; otherwise, execute step 4.

[0110] Step 3: Determine the first height as the tailgate height.

[0111] Step 4: Open the tailgate to the default height or maximum height;

[0112] Step 5: Determine whether the door is open. If so, proceed to step 6; if not, proceed to step 8.

[0113] Step 6: Determine whether the door is closed. If so, proceed to step 7; if not, proceed to step 9.

[0114] Step 7: Determine whether there is someone sitting in the main driver's seat. If so, proceed to step 8; if not, proceed to step 10.

[0115] Step 8. Keep the tailgate height unchanged.

[0116] Step 9: Determine whether the pressure sensor signal change of the main driver's seat exceeds the set threshold. If so, execute step 10; if not, execute step 6.

[0117] Step 10: The user sitting in the main driving seat uses the tailgate;

[0118] Step 11, obtaining the memory seat information of the main driver's seat, and determining the target height H0 of the main driver's seat according to the memory seat information;

[0119] Step 12: determine whether the difference between H0 and the preset height HX is less than 3 cm. If so, execute step 15; if not, execute step 13;

[0120] Step 13, determining the tailgate height according to the target height H0;

[0121] Step 14: Obtain a tailgate height adjustment signal △H and correct the tailgate height;

[0122] Step 15: Output the tailgate height corresponding to the preset height.

[0123] In another specific example, Figure 4 As described above, if the target user is a user sitting in the main driving seat, the target height calculation process of the target user is as follows:

[0124] The pressure sensor detects the position of point H (the target point of the seat), and defines the distance from point H to the front of the seat as K0 (the first distance). Define the distance between the knee joint and the front of the seat as △X = 3cm (the second distance). Using the height of the driver's seat H1, the horizontal distance from the front of the driver's seat to the pedal L, and the distance between the knee joint and the front of the seat, calculate the distance from the knee joint to the heel point.

[0125] Look up the length and angle of the seat belt use part, and the relationship table with the driver's shoulder position to obtain the vertical distance H2 from the driver's shoulder position to the seat. Calculate the length from point H to the center of the two shoulders through the seat back inclination angle ɑ.

[0126] The driver’s arm length K3 is collected through the camera inside the main driver’s seat.

[0127] H0=K1+ΔX+K0+K2+K3;

[0128] Determine H0 as the target height of the target user.

[0129] In an embodiment of the present invention, there are the following ways to determine the height of the tailgate:

[0130] The tailgate is opened, the car door is opened and then closed, and no one is sitting in the main driving seat. The user sitting in the main driving seat uses the tailgate, and the height of the tailgate is adjusted to the adaptive height H0.

[0131] The tailgate is open, the car door is opened and then closed, and someone is sitting in the main driving seat. The user sitting in the main driving seat does not use the tailgate, and the tailgate remains at the default height.

[0132] The tailgate is opened, the car door is not closed after opening, the change of the pressure sensor detecting the main driver's seat is greater than the preset threshold, the user sitting in the main driver's seat uses the tailgate, and the height of the tailgate is adjusted to an adaptive height.

[0133] The tailgate is open, the door is not closed after opening, the pressure sensor change of the main driver's seat is detected to be less than or equal to the preset threshold, and the door closing signal or pressure sensor change is waited;

[0134] The tailgate is open, the door is not open, and no one is sitting in the main driver's seat. The sensor is faulty and the tailgate remains at the default height or maximum height.

[0135] The tailgate is open, the doors are not open, someone is in the driver's seat, and the non-driver uses the tailgate. The tailgate opens to the default height or maximum height.

[0136] The tailgate is opened and it is determined whether it is in the preset position. If it is in the preset position, the first height is used as the tailgate height.

[0137] The tailgate opens at an adaptive height, adjusts the tailgate height, and corrects the corresponding relationship table between the user's target height and the tailgate height based on the adjusted tailgate height.

[0138] The technical solution of this embodiment is to determine the target height of the target user according to the memory seat information corresponding to the target user when the tailgate opening signal is received and the tailgate user is the target user; and when the difference between the target height and the preset height is greater than the difference threshold, determine the tailgate height according to the target height, so as to obtain a tailgate height suitable for the user, thereby improving the user's experience.
