Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a seat adjustment method, device, equipment and storage medium. BACKGROUND

[0002] During driving, the driver sits on the seat for a long time, and the unreasonable man-machine position is prone to cause muscle injury and fatigue. Therefore, reasonable adjustment of the seat position has become an important research topic in the field of vehicle technology.

[0003] In real life, a vehicle is often configured with multiple drivers, especially for large vehicles such as trucks and buses. In order to meet the seating needs of drivers of different sizes, the seats of the driving position are set to have a large adjustment range. After replacing the driver each time, the current driver manually or electrically adjusts the approximate position of the seat in front of and behind, height, and backrest angle according to personal habits, so as to meet the driving needs of the driver.

[0004] However, such an adjustment method has poor operation convenience. The driver needs to wait for a certain period of time for the completion of the seat adjustment. In addition, the same driver often adjusts the seat to different positions each time, which cannot achieve an accurate driving position and cannot meet the requirements of ergonomics, so the best driving experience cannot be achieved. SUMMARY

[0005] The present application provides a seat adjustment method, device, equipment and storage medium to solve the problem of low seat adjustment accuracy.

[0006] According to an aspect of the present application, a seat adjustment method is provided, comprising:

[0007] Obtaining lower limb parameters of the driver; wherein the lower limb parameters include foot length, calf length and thigh length;

[0008] Obtaining posture parameters of the driver; wherein the posture parameters include pedal plane angle, knee joint bending angle and seat inclination angle;

[0009] According to the lower limb parameters, posture parameters and foot bottom included angle of the driver, obtaining coordinate parameters of a seat reference point, and adjusting the seat position according to the coordinate parameters of the seat reference point.

[0010] The lower limb parameters of the driver are obtained according to the height parameters and gender parameters of the driver. Thus, the lower limb parameters are obtained based on the height parameters, which greatly improves the accuracy of the lower limb parameters compared with the manually measured or predicted lower limb parameters of the driver.

[0011] The driver's lower limb parameters are obtained according to the height parameter and the gender parameter of the driver, and the height parameter of the driver is obtained according to the eye height of the driver in the sitting posture, the heel point position, the gender parameter and the initial height of the seat. The height parameter is calculated according to the actual measurement parameter of the driver's seat, which avoids the pre-input of the height parameter, improves the convenience of obtaining the height parameter, avoids the input error of the height parameter, improves the accuracy of obtaining the height parameter, and further realizes the accurate adjustment of the seat position.

[0012] The posture parameter of the driver is obtained, and the initial posture parameter is obtained according to the preset angle range corresponding to the pedal plane angle, the knee joint bending angle and the seat inclination angle. The initial posture parameter includes the initial pedal plane angle, the initial knee joint bending angle and the initial seat inclination angle. The coordinate parameter of the seat reference point is obtained according to the lower limb parameter, the posture parameter and the foot bottom included angle of the driver, and the seat position is adjusted according to the coordinate parameter of the seat reference point. The initial coordinate parameter of the seat reference point is obtained according to the lower limb parameter, the initial posture parameter and the foot bottom included angle of the driver, and the seat position is adjusted according to the initial coordinate parameter of the seat reference point. Thus, in the initial state that the driver sits on the driver's seat, the vehicle is not started and the seat inclination angle is not adjusted, the initial coordinate parameter of the seat reference point can be calculated based on the above initial posture parameter, the lower limb parameter and the foot bottom included angle, so as to realize the pre-adjustment of the seat in the initial state after the driver enters the driver's seat.

[0013] The posture parameter of the driver is obtained, and the knee joint bending angle is obtained according to the pedal plane angle and the seat inclination angle. The knee joint bending angle calculated by the above method more accurately reflects the actual driving posture of the driver, and further improves the accuracy of the coordinate parameter of the seat reference point.

[0014] After the knee joint bending angle is obtained according to the pedal plane angle and the seat inclination angle, if it is determined that the knee joint bending angle is not located in the corresponding preset angle range, the standard knee joint angle is obtained according to the preset angle range corresponding to the knee joint bending angle. The coordinate parameter of the seat reference point is obtained according to the lower limb parameter, the posture parameter and the foot bottom included angle of the driver, and the coordinate parameter of the seat reference point is obtained according to the lower limb parameter, the pedal plane angle, the seat inclination angle, the standard knee joint bending angle and the foot bottom included angle of the driver. The coordinate parameter of the seat reference point calculated in this way makes the coordinate parameter of the seat reference point calculated when the calculated knee joint bending angle exceeds the preset angle range based on the driving posture of the driver in the comfortable state, so that the calculation result is more consistent with the actual driving scene of the driver, and the calculation precision of the coordinate parameter of the seat reference point is improved.

[0015] The method comprises the following steps: acquiring the coordinate parameters of the seat reference point according to the lower limb parameters, the posture parameters and the foot bottom included angle of the driver, and adjusting the seat position according to the coordinate parameters of the seat reference point. Therefore, the coordinate parameters of the seat reference point are corrected according to the weight parameters and the height parameters of the driver, the accurate coordinate parameters of the seat reference point are acquired, the adjustment accuracy of the seat position is improved, and the driving comfort of the driver is improved.

[0042] Embodiment One

[0043] Figure 1 A flowchart of a seat adjustment method provided for the first embodiment of the present application, the present embodiment can be applicable to adjusting the seat position according to the lower limb parameters, posture parameters and foot clamping angle of the driver. The seat adjustment device can be realized in the form of hardware and / or software, and the seat adjustment device is configured in an electronic device, typically, in a vehicle terminal device or a vehicle control device. As shown in the figure, the method comprises: Figure 1

[0044] S101, acquiring the lower limb parameters of the driver; wherein the lower limb parameters include foot length, calf length and thigh length.

[0045] ​The foot length is the length from the ankle joint of the driver to the heel point; the calf length is the length from the ankle joint of the driver to the knee joint; and the thigh length is the length from the knee joint of the driver to the seat reference point; wherein the seat reference point, i.e. the seat H point, is a reference point of the position of the driver in the seat, and is also the rotation point (i.e. the hip point) at which the torso and the thigh of the driver are connected.

[0046] The lower limb parameters can be obtained according to the identity information of the driver; for example, when the face information of the driver is detected by an in-vehicle camera assembly, the identity information of the driver is determined through face recognition technology, and then the matching lower limb parameters are obtained according to the identity information of the driver through the locally stored lower limb information or the lower limb information stored in the background server; at the same time, the identity information of the driver can also be obtained according to the fingerprint information and identity recognition card information input by the driver in the driving position, and the identity recognition information sent by the driver through a terminal device such as a mobile phone; optionally, in the embodiment of the present application, the manner of obtaining the identity information of the driver is not specifically limited, and the manner of obtaining and the storage manner of the lower limb parameters are also not specifically limited.

[0047] Optionally, in the embodiment of the present application, the obtaining of the lower limb parameters of the driver comprises: obtaining the lower limb parameters of the driver according to the height parameter and the gender parameter of the driver. Specifically, the length information of each limb part of the human body has a certain correlation with the height, and can be obtained through the following equation:

[0048] L1 = 0.3H - K x2 (Formula 1-1)

[0049]

[0050] L3 = 0.0823H - K x4 (Formula 1-3)

[0051] Wherein, L1 represents the foot length; L2 represents the calf length; L3 represents the thigh length; H represents the height parameter of the driver; K x2 , K x3 , and K x4 respectively represent the foot coefficient, the calf coefficient and the thigh coefficient; the foot coefficient, the calf coefficient and the thigh coefficient correspond to different values according to different genders of the driver; when the driver is male, K x2 = K m2 , K x3 = K m3 , and K x4 = K m4 ; when the driver is female, K x2 = K f2 , K x3 = Kf3 , K x4 = K f4 ; K m2 , K m3 , K m4 , K f2 , K f3 , K f4 are constant values; thereby achieving lower limb parameter acquisition based on height parameters, greatly improving the accuracy of lower limb parameter acquisition compared to manually measured or predicted lower limb parameters of the driver.

[0052] S102, acquiring a posture parameter of the driver; wherein the posture parameter includes a pedal plane angle, a knee joint bending angle, and a seat inclination angle.

[0053] The pedal plane angle is a value of the change in the pedal angle caused by the driver stepping on the pedal during driving, which can be acquired by a sensor (i.e., a pedal sensor) located at the pedal position; the knee joint bending angle is the angle between the upper leg and the lower leg when the driver is in a driving sitting position, i.e., the angle between the two limbs connected by the knee joint, which can be pre-configured as a fixed value; the seat inclination angle is the seat inclination angle adjusted by the driver according to personal habits, which can be acquired by a Hall sensor (i.e., an inclination sensor) for detecting the seat inclination angle.

[0054] S103, acquiring a coordinate parameter of a seat reference point according to the lower limb parameter, the posture parameter, and the foot bottom included angle of the driver, and adjusting the seat position according to the coordinate parameter of the seat reference point.

[0055] The foot bottom included angle is the included angle between the line connecting the heel point and the ankle point and the shoe sole plane, which can be directly obtained by ergonomics, i.e., the foot bottom included angle is also a pre-configured constant value; after acquiring the lower limb parameter, the posture parameter, and the foot bottom included angle of the driver, the coordinate parameter of the seat reference point can be acquired by the following equation:

[0056]

[0057] wherein a1 represents the pedal plane angle, a2 represents the knee joint bending angle, and a3 represents the seat inclination angle; β represents the foot bottom included angle; X represents the coordinate parameter of the seat reference point in the front-back movement direction, i.e., the coordinate parameter of the seat reference point on the slide rail, and Z represents the coordinate parameter of the seat reference point in the height direction.

[0058] Optionally, in the embodiment of the present application, the obtaining the posture parameter of the driver comprises: obtaining an initial posture parameter according to a preset angle range corresponding to the pedal plane angle, the knee joint bending angle and the seat inclination angle; wherein the initial posture parameter comprises an initial pedal plane angle, an initial knee joint bending angle and an initial seat inclination angle; and the obtaining the coordinate parameter of the seat reference point according to the lower limb parameter, the posture parameter and the foot bottom included angle of the driver, and adjusting the seat position according to the coordinate parameter of the seat reference point, comprises: obtaining an initial coordinate parameter of the seat reference point according to the lower limb parameter, the initial posture parameter and the foot bottom included angle of the driver, and adjusting the seat position according to the initial coordinate parameter of the seat reference point.

[0059] Specifically, when the driver just sits on the driver's seat, the vehicle is not started, and at this time, the pedal plane angle of the driver on the pedal cannot be obtained, and since the driver has not adjusted the seat inclination angle, the expected seat inclination angle of the driver cannot be obtained either. At this time, according to the preset angle range of the pedal plane angle, the knee joint bending angle and the seat inclination angle, the average preset angle of the maximum preset angle and the minimum preset angle is taken as the posture parameter at the current time, that is, the initial posture parameter.

[0060] For example, the maximum pedal plane angle and the minimum pedal plane angle are configured when the vehicle is manufactured, and the average value of the maximum pedal plane angle and the minimum pedal plane angle is taken as the initial pedal plane angle. When the knee joint bending angle is in the range of 118 degrees to 135 degrees, the driver is in a relatively comfortable driving position, and the average value between the maximum knee joint bending angle and the minimum knee joint bending angle can be taken as the initial knee joint bending angle. The adjustable range of the seat inclination angle is also configured when the vehicle is manufactured, for example, the seat inclination angle is in the range of -2 degrees to 12 degrees, and the average value between the maximum seat inclination angle and the minimum seat inclination angle can also be taken as the initial seat inclination angle.

[0061] Therefore, in the initial state that the driver sits on the driver's seat, the vehicle is not started and the seat inclination angle is not adjusted, the initial coordinate parameter of the seat reference point can be calculated and obtained based on the initial posture parameter, the lower limb parameter and the foot bottom included angle, so as to realize the initial state of the seat pre-adjustment after the driver enters the driver's seat.

[0062] Optionally, in the embodiment of the present application, the obtaining the coordinate parameter of the seat reference point according to the lower limb parameter, the posture parameter and the foot bottom included angle of the driver, and adjusting the seat position according to the coordinate parameter of the seat reference point, comprises: correcting the coordinate parameter of the seat reference point according to the height parameter and the weight parameter of the driver to obtain a corrected coordinate parameter, and adjusting the seat position according to the corrected coordinate parameter of the seat reference point.

[0063] Specifically, the seat reference point corresponding to the sitting posture of the driver with different body weight is obviously different, and the body weight affects the coordinate parameter of the seat reference point in the front-back moving direction, therefore, the body weight parameter of the driver is taken as the influencing factor of the seat reference point, and the coordinate parameter of the seat reference point is corrected; wherein the body weight parameter can be detected and acquired through the pressure sensor of the seat position, or can be acquired and matched according to the identity information of the driver, through the body weight information stored locally or the body weight information stored in the background server; the corrected coordinate parameter of the seat reference point is calculated and acquired through the following equation:

[0064]

[0065] Wherein X represents the coordinate parameter of the seat reference point in the front-back moving direction calculated and acquired, that is, the original coordinate parameter before adjustment; X E represents the corrected coordinate parameter of the seat reference point; W represents the body weight parameter of the driver; H represents the height parameter of the driver; K1 and K2 represent correction coefficients and are constant values; therefore, the coordinate parameter of the seat reference point is corrected according to the body weight parameter and the height parameter of the driver, the accurate coordinate parameter of the seat reference point is acquired, the adjustment accuracy of the seat position is improved, and the driving comfort of the driver is improved.

[0066] The technical scheme of the embodiment of the application, after acquiring the lower limb parameter and the posture parameter of the driver, acquires the coordinate parameter of the seat reference point according to the lower limb parameter, the posture parameter and the foot bottom included angle of the driver, and adjusts the seat position according to the coordinate parameter of the seat reference point, realizes the automatic adjustment of the seat position, improves the operation convenience of the seat adjustment, reduces the time consumption required by the driver for waiting for the completion of the seat adjustment, avoids the adjustment error caused by the manual adjustment of the driver, guides the driver to participate in driving in the correct driving posture, and improves the driving experience.

[0067] Embodiment two

[0068] Figure 2 A flow chart of a seat adjustment method provided by the embodiment two of the application, based on the embodiment one, the height parameter of the driver is calculated and acquired according to the related parameters such as the sitting posture eye height and the heel point position of the driver. Figure 2 As shown in the figure, the method comprises:

[0069] S201, acquiring the height parameter of the driver according to the sitting posture eye height, the heel point position, the gender parameter and the initial height of the seat of the driver.

[0070] The sitting eye height is the height of the driver's eyes when the driver sits on the driving seat. The driver's eye position in an image can be obtained according to the facial image of the driver captured by the in-vehicle camera assembly, and then the driver's eye height can be determined according to the height of the camera assembly. The heel point is the contact point between the heel and the support point of the accelerator pedal when the heel is placed on the accelerator pedal. The heel point position is configured as a fixed value when the vehicle is manufactured, and the actual value can also be obtained through a corresponding displacement sensor. The initial seat height is the actual height of the seat adjusted at the current time, specifically the height difference between the upper surface of the seat and the heel point, which can be obtained through a Hall sensor (i.e., a seat height detection sensor) for detecting the height of the seat.

[0071] After obtaining the sitting eye height of the driver, the heel point position, the gender parameter and the initial seat height, the height parameter of the driver can be obtained through the following equation:

[0072] H = 2 (H ie -H is )- K x1 (Equation 2-1)

[0073] wherein H represents the height parameter of the driver; H ie represents the difference between the sitting eye height of the driver and the heel point position; H is represents the initial seat height; K x1 represents the height coefficient; the height coefficient corresponds to different values according to different gender parameters of the driver; when the driver is male, K x1 = K m1 ; when the driver is female, K x1 = K f1 ; K m1 and K f1 are constant values.

[0074] S202, obtaining the lower limb parameter of the driver according to the height parameter and the gender parameter of the driver.

[0075] S203, obtaining the posture parameter of the driver; wherein the posture parameter includes the pedal plane angle, the knee joint bending angle and the seat inclination angle.

[0076] S204, obtaining the coordinate parameter of the seat reference point according to the lower limb parameter, the posture parameter and the foot bottom included angle of the driver, and adjusting the seat position according to the coordinate parameter of the seat reference point.

[0077] The technical scheme of the embodiment of the present application first acquires the height parameter of the driver according to the sitting posture eye height, heel point position, gender parameter and initial height of the seat of the driver, then acquires the lower limb parameter of the driver according to the height parameter and gender parameter of the driver, and acquires the coordinate parameter of the seat reference point according to the lower limb parameter, posture parameter and foot bottom included angle of the driver. Compared with the storage parameter value acquired according to the user identity information or the height parameter input by the user himself, the height parameter is calculated according to the actual measurement parameter of the driving position, which not only avoids the pre-input of the height parameter and improves the convenience of acquiring the height parameter, but also avoids the input error of the height parameter and improves the accuracy of acquiring the height parameter, thereby realizing the accurate adjustment of the seat position.

[0078] Embodiment three

[0079] Figure 3 A flowchart of a seat adjustment method provided by the third embodiment of the present application, which is based on the first embodiment, calculates and acquires the knee joint bending angle according to the pedal plane angle and the seat inclination angle. Figure 3 As shown in the figure, the method comprises:

[0080] S301, acquiring the lower limb parameter of the driver; wherein the lower limb parameter comprises the foot length, calf length and thigh length.

[0081] S302, acquiring the pedal plane angle and the seat inclination angle of the driver, and acquiring the knee joint bending angle according to the pedal plane angle and the seat inclination angle.

[0082] The knee joint bending angle is a human joint parameter on the lower limb of the driver, but when the driver steps on the pedal to cause the change of the pedal plane angle, the knee joint bending angle will change; similarly, when the driver adjusts the seat inclination angle, the seat inclination angle will cause the change of the human posture, which will also cause the change of the knee joint bending angle; therefore, according to the calculation equation or data comparison table configured in advance, the knee joint bending angle matched at the current time can be acquired by calculation or table lookup according to the pedal plane angle and the seat inclination angle acquired at the current time, thereby completing the acquisition of the knee joint bending angle; compared with the constant value of the knee joint bending angle, the knee joint bending angle acquired by the above-mentioned calculation method more accurately reflects the actual driving posture of the driver, and further improves the accuracy of the coordinate parameter of the seat reference point.

[0083] S303, if it is determined that the knee joint bending angle is located in the corresponding preset angle range, acquiring the coordinate parameter of the seat reference point according to the lower limb parameter, pedal plane angle, seat inclination angle, standard knee joint bending angle and foot bottom included angle of the driver.

[0084] The preset angle range corresponding to the knee bending angle represents an angle range in a comfortable driving posture, and thus, if the calculated knee bending angle is within the corresponding preset angle range, the calculated knee bending angle is directly used to calculate the coordinate parameter of the seat reference point in combination with other parameters.

[0085] In S304, if it is determined that the knee bending angle is not within the corresponding preset angle range, a standard knee bending angle is obtained according to the preset angle range corresponding to the knee bending angle.

[0086] In S305, the coordinate parameter of the seat reference point is obtained according to the lower limb parameter of the driver, the pedal plane angle, the seat inclination angle, the standard knee bending angle, and the foot bottom included angle.

[0087] If the calculated knee bending angle is outside the corresponding preset angle range, it indicates that the driver is driving in an uncomfortable posture, and the driver will adjust the body posture to adapt to the change of the knee angle. At this time, the calculated knee bending angle is different from the actual state, and thus, the knee bending angle is not substituted into the height parameter calculation equation, but a standard knee bending angle, i.e., a knee bending angle in the best driving posture, is assigned to the knee bending angle as the knee bending angle at the current time. The standard initial knee bending angle is the same as the initial knee bending angle, i.e., the average value between the maximum knee bending angle and the minimum knee bending angle. The coordinate parameter of the seat reference point is calculated in this way, so that when the calculated knee bending angle is outside the preset angle range, the coordinate parameter of the seat reference point can be calculated based on the driving posture of the driver in the comfortable state, so that the calculation result is more consistent with the actual driving scene of the driver, and the calculation accuracy of the coordinate parameter of the seat reference point is improved.

[0088] The technical solution of the embodiment of the application calculates the knee bending angle according to the pedal plane angle and the seat inclination angle, which is more accurate than configuring a constant value for the knee bending angle to reflect the actual driving posture of the driver. If the calculated knee bending angle is outside the corresponding preset angle range, the initial knee bending angle is assigned to the knee bending angle, so that the coordinate parameter of the seat reference point is calculated based on the driving posture of the driver in the comfortable state, so that the calculation result is more consistent with the actual driving scene of the driver, and the calculation accuracy of the coordinate parameter of the seat reference point is improved.
