[0068] It should be noted that any symbols and / or numbers present in the specification that are not marked in the accompanying drawings are not reference numerals.

[0069] The optional embodiments of this application are described in detail below with reference to the accompanying drawings.

[0070] The embodiments provided in this application are embodiments of a method for adjusting the seat surface of a vehicle.

[0071] The following is combined with Figure 1 The embodiments of this application will be described in detail.

[0072] Step S101: Obtain the physical characteristic values ​​of the vehicle occupants.

[0073] In some specific embodiments, obtaining the physical characteristic values ​​of vehicle occupants includes:

[0074] Step S101a: When the occupant is outside the vehicle, the occupant's body feature values ​​are acquired through a depth camera outside the vehicle.

[0075] Depth cameras provide more detailed image information than traditional cameras, including the distance, size, and shape of objects. Depth cameras capture depth images.

[0076] A depth image, also known as a distance image, is an image that uses the distance values ​​(i.e., depth values) of various points in a scene captured by a depth camera as pixels. It directly reflects the geometry of the scene's surface. For example, a depth camera can be mounted on the body of a car above a door. By capturing a depth image of an occupant approaching the door, the occupant's body feature values ​​can be obtained by analyzing the depth image. These body feature values ​​include, for example, lower leg length, foot height, heel thickness, and the distance from the occupant's eyes to their hips.

[0077] Because occupants are outside the vehicle and their bodies are in an upright position, the body feature values ​​obtained are more accurate. Of course, obtaining occupant body feature values ​​is not limited to this. For example, a depth camera can be installed inside the vehicle.

[0078] Step S102: Obtain the knee height value and the eye position of the occupant simulating sitting in the current seat based on the body feature values.

[0079] Knee height refers to the height of an occupant's knee from the ground when their lower leg is perpendicular to the ground.

[0080] In this embodiment, the positions are all located within a preset three-dimensional coordinate system, which includes a first coordinate axis, a second coordinate axis, and a third coordinate axis. The first coordinate axis and the second coordinate axis form a first horizontal plane, and the third coordinate axis is perpendicular to the first horizontal plane. The height coordinate value is the value of the third coordinate axis. For example, the preset three-dimensional coordinate system is a vehicle body coordinate system or a world coordinate system.

[0081] By summing the distance from the occupant's eyes to their buttocks and the height coordinate of the seat center point (i.e., the third coordinate axis value), the height coordinate of the occupant's eyes while seated can be obtained. The eye position can then be determined by combining the first and second coordinate axis values ​​of the seat center point with the eye height coordinate. For example, if the first coordinate axis value of the seat center point is 10, the second coordinate axis value is 20, and the eye height coordinate is 60, then the eye position is (10, 20, 60).

[0082] In some specific embodiments, the body feature values ​​include: calf length value, foot height value, and heel thickness value.

[0083] The lower leg length value refers to the length from the knee to the ankle.

[0084] Foot height refers to the height from the ankle to the bottom of the heel.

[0085] Accordingly, obtaining the knee height value based on the body feature value includes:

[0086] Step S102-1: Obtain the knee height value based on the sum of the lower leg length value, the foot height value, and the heel thickness value.

[0087] For example, if the calf length is 30cm, the foot height is 5cm, and the heel thickness is 2cm, then the knee height = 30 + 5 + 2 = 37cm.

[0088] Step S103: Obtain the adjustment coefficient value based on the eye position and the preset midpoint position of the window adjacent to the current seat.

[0089] In some specific embodiments, obtaining the adjustment coefficient value based on the eye position and the preset midpoint position of the window adjacent to the current seat includes the following steps:

[0090] Step S103-1: Determine the horizontal plane of the midpoint passing through the preset midpoint position.

[0091] Step S103-2: When the height coordinate value of the eye position is less than or equal to the height coordinate value of the midpoint horizontal plane, the adjustment coefficient value is determined to be zero.

[0092] The height coordinate value of the eye position is less than or equal to the height coordinate value of the midpoint horizontal plane, which can be understood as the eye position being below the midpoint horizontal plane or on the midpoint horizontal plane.

[0093] An adjustment factor of zero means that no additional adjustments are needed.

[0094] For example, if the height coordinate of the midpoint horizontal plane is 65 and the height coordinate of the eye position is 60, then the adjustment coefficient is determined to be zero.

[0095] In some specific embodiments, the method further includes:

[0096] Step S103-3: When the height coordinate value of the eye position is greater than the height coordinate value of the midpoint horizontal plane, determine the target straight line passing through the eye position and the preset midpoint position.

[0097] The height coordinate value of the eye position is greater than the height coordinate value of the midpoint horizontal plane, which can be understood as the eye position being above the midpoint horizontal plane.

[0098] For example, if the height coordinate of the midpoint on the horizontal plane is 65 and the height coordinate of the eye position is 70, then the target straight line is determined.

[0099] Step S103-4: Obtain the angle between the target line and the horizontal plane at the midpoint.

[0100] Step S103-5: When the included angle value is less than or equal to the preset included angle threshold, the adjustment coefficient value is determined to be zero.

[0101] For example, if the preset angle threshold is 5°, and the angle value is 3°, which is less than the preset angle threshold, then the adjustment coefficient value is determined to be zero.

[0102] In some specific embodiments, the method further includes:

[0103] Step S103-6: When the included angle value is greater than the preset included angle threshold, a limited height coordinate value is obtained based on the preset included angle threshold, the projection position of the eye position on the horizontal plane of the midpoint, and the preset midpoint position.

[0104] The height limit coordinate value is the boundary value that restricts the height coordinate value of the passenger's eye position. When the height coordinate value of the passenger's eye position exceeds the height limit coordinate value, an additional adjustment coefficient value is added when adjusting the current seat height.

[0105] In some specific embodiments, when the included angle value is greater than a preset included angle threshold, obtaining a limited height coordinate value based on the preset included angle threshold, the projection position of the eye position on the horizontal plane of the midpoint, and the preset midpoint position includes the following steps:

[0106] Step S103-6-1: When the included angle value is greater than the preset included angle threshold, determine the length value from the projection position to the preset midpoint position.

[0107] For example, if the preset included angle threshold is 5°, and the included angle value is 7°, which is greater than the preset included angle threshold, the projection position is (16, 30, 65), and the preset midpoint position is (10, 20, 65). Then, the projection value from the projection position to the preset midpoint position on the first coordinate axis is 16 - 10 = 6, and the projection value from the projection position to the preset midpoint position on the second coordinate axis is 30 - 20 = 10. According to the Pythagorean theorem, the length from the projection position to the preset midpoint position is 11.662.

[0108] Step S103-6-2: Obtain the maximum height value based on the length value and the preset included angle threshold.

[0109] For example, continuing with the above example, the preset included angle threshold is 5°, the length value (L) is 11.662, and the maximum height value (h1) = 11.662 × tan5° = 1.02.

[0110] Step S103-6-3: Obtain the limited height coordinate value based on the sum of the height coordinate value of the projected position and the maximum height value.

[0111] For example, continuing the example above, the projection position is (16, 30, 65), the height coordinate value of the projection position is 65, and the limited height coordinate value = 1.02 + 65 = 66.02.

[0112] Step S103-7: Obtain the adjustment coefficient value based on the absolute value of the difference between the height coordinate value of the eye position and the limited height coordinate value.

[0113] For example, continuing with the example above, if the height coordinate of the eye position is 70 and the limit height coordinate is 66.02, then the adjustment coefficient value = 70 - 66.02 = 3.98.

[0114] Step S104: Determine the seat height value of the current seat based on the difference between the knee height value and the adjustment coefficient value.

[0115] To ensure leg comfort and body safety, occupants must keep their lower legs roughly perpendicular to the vehicle ground. Therefore, when the occupant has a good field of vision, the adjustment coefficient is set to zero, and no additional seat adjustments are made. This ensures that the occupant's lower legs are roughly perpendicular to the vehicle ground after sitting down. For example, if the knee height is 37 and the occupant has a good field of vision, the seat height is adjusted to 37 as well.

[0116] When the occupant's visibility is poor, the seat can be adjusted by adjusting the coefficient value to ensure that the occupant's lower legs are basically perpendicular to the ground after sitting down, while also obtaining a better field of vision. For example, if the knee height value is 37, the occupant's visibility is poor, and the adjustment coefficient value is 3.98, then the current seat height value = 37 - 3.98 = 33.02.

[0117] Step S105: Adjust the seat height of the current seat based on the current seat seat height value.

[0118] This application embodiment acquires the body characteristic values ​​of a vehicle occupant, obtains the knee height value and the eye position of the occupant simulating sitting in the current seat based on the body characteristic values, then obtains an adjustment coefficient value based on the eye position and the preset midpoint position of the window adjacent to the current seat, and finally determines the seat surface height value of the current seat based on the difference between the knee height value and the adjustment coefficient value, and adjusts the seat surface height of the current seat according to the current seat surface height value. While ensuring that the occupant's lower legs are basically perpendicular to the vehicle ground, ensuring leg comfort and body safety, it also allows the occupant's eyes to obtain a better view of the outside scenery from the window. This ensures that the occupant can view the scenery outside the window from the seat, improves occupant safety during driving, and reduces travel fatigue.
