In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In order to solve the problems that a user feels inconvenient and troublesome to operate when fastening a safety belt, the embodiment of the application provides a safety belt lock catch adjusting method and a safety belt lock catch adjusting device. The method and apparatus provided by the embodiments of the present application may be implemented by an electronic device, such as a Vehicle Control Unit (VCU). In other words, the method may be performed by software or hardware installed in the electronic device. These electronic devices may include, but are not limited to: one or more of intelligent terminal devices such as a VCU, an Electronic stability control system (ESC), a smart phone, a Personal Computer (PC), a notebook computer, a tablet computer, and a wearable device.

The following first describes a seat belt buckle adjustment method provided in an embodiment of the present application.

Fig. 1 shows a schematic flow chart of a seat belt buckle adjustment method according to an embodiment of the present application. As shown in fig. 1, the method may include:

step 101, start.

And 102, judging whether a preset trigger condition is met, if so, executing a step 103, and otherwise, executing a step 106.

The preset trigger condition may be regarded as a trigger condition for triggering the seat belt buckle adjustment method provided in the embodiment of the present application, and when the trigger condition is satisfied, the method is triggered, otherwise, the method is not triggered. For example, the preset trigger condition may include, but is not limited to, at least one of the following conditions: receiving a vehicle unlocking signal, opening a vehicle door (which can be any vehicle door on the automobile) by a user, closing the vehicle door by the user and the like.

And 103, acquiring a first image in the vehicle.

The current image in the vehicle can be collected by the camera in the vehicle to be used as the first image.

104, determining whether a user is seated in the target seat in the vehicle or not based on the first image; if so, go to step 105, otherwise, go back to step 103.

The target seat can be any seat in the vehicle. After the first image is collected, whether a person sits in the vehicle can be monitored through an image recognition algorithm, and when the person is monitored to sit, the specific seat where the user sits is judged through the image recognition algorithm, namely the target seat is determined; when no person is detected to be seated, the step 103 is returned to continue to collect the current images in the vehicle so as to continue to detect whether a person is seated.

And 105, controlling a target seat belt lock to be lifted to a target height, wherein the target seat belt lock is a seat belt lock corresponding to the target seat.

The purpose of step 105 is to facilitate the user's insertion of the seat belt buckle into the target seat belt buckle. Generally, the height of the seat belt buckle in the initial position is lower than the seat surface of the seat, so that the user of the target seat can conveniently find the target seat belt buckle, and the seat belt buckle is inserted into the target seat belt buckle, so that the target seat belt buckle can be lifted relative to the seat surface to a position which is flush with or slightly higher than the leg surface of the user (for example, higher than the leg surface by a preset height). Accordingly, the height of the leg surface of the user (which may be referred to as a first height) with respect to the seat surface of the seat, which is similar to the shape of the user sitting on the target seat, may be determined in advance through big data analysis, and then the target height may be determined based on the first height. For example, the target height may be determined according to the first height and a height (which may be referred to as a second height) of the seat surface of the seat belt latch at the initial position, and specifically, if the top end of the seat belt latch is lower than the seat surface at the initial position, the target height may be set to be a sum of the first height and the second height; the target height may be set to a difference between the first height and the second height if the top end of the seatbelt buckle is lower than the seat surface when the seatbelt buckle is at the initial position. Of course, the target height may also be preset to a fixed value according to experience, and the determination manner of the target height in the embodiment of the present application is not particularly limited.

And step 106, ending.

It is understood that the process can be ended after the steps 103, 104 and 105 are performed for all seats in the vehicle, so that the passenger seated on each seat can quickly and conveniently find the seat belt buckle when wearing the seat belt, and then quickly and easily insert the seat belt buckle therein.

According to the safety belt lock adjusting method provided by the embodiment shown in fig. 1, after a user is recognized to be seated on any seat in a vehicle, the safety belt lock corresponding to the seat can be automatically lifted, so that the user can conveniently find the safety belt lock and insert the safety belt when the user fastens the safety belt, the problems that the user feels inconvenient and troublesome to operate when fastening the safety belt are solved, and after the user is seated, the safety belt lock is lifted, and the user can find the safety belt lock and insert the safety belt into the safety belt buckle in the most comfortable manner.

In addition, the height of the safety belt lock catch in the related technology is flush with the seat surface of the seat, and the safety belt lock catch is fixed and cannot be adjusted, so that the user is inconvenient to fasten the safety belt after sitting in the seat; part motorcycle type safety belt hasp connecting portion are soft material, fall into the seat gap easily. In the scheme, the target safety belt lock catch is in a contraction state when not in use, and the height can be automatically adjusted when in use, so that the problem that the safety belt lock catch is difficult to find after a person takes a seat can be solved, and the safety belt lock catch can be prevented from falling into a seat gap.

Furthermore, when the user does not sit on the seat, the safety belt lock catch is retracted, and the safety belt lock catch is lifted after the user sits on the seat, so that the influence on the comfort of fastening the safety belt and the seat caused by sitting on the safety belt lock catch when the user sits on the seat can be avoided.

Optionally, as shown in fig. 2, another embodiment of the present application provides a seat belt buckle adjusting method, which includes, in addition to the steps 102, 103, 104, and 105, further including:

step 107, detecting whether a seat belt buckle on the target seat is inserted into the target seat belt buckle; if so, go to step 108, otherwise, go to step 106.

In a specific implementation, whether the seat belt buckle on the target seat is inserted into the target seat belt buckle or not may be detected by a detection device such as a sensor (e.g., a pressure sensor) on the target seat belt buckle.

And step 108, acquiring a second image in the vehicle.

Specifically, the image of the vehicle at this time can be acquired by the in-vehicle camera as the second image. The second image comprises a target user and a safety belt tied on the body of the target user, and the target user is a user on the target seat.

Step 109, determining whether the safety belt worn by the target user is in a comfortable position based on the second image; if yes, go to step 106, or go to step 111 in FIG. 4; otherwise, step 110 is performed.

Specifically, in step 109, the type of the target user and the position information of the seat belt worn by the target user may be determined based on the second image; then, obtaining standard position information when the users of the body types wear safety belts, wherein the standard position information is obtained by analyzing first big data, and the first big data comprises image data when the safety belts worn by the users of the body types are at comfortable positions; and finally, comparing the position information of the safety belt fastened by the target user with the standard position information to determine whether the safety belt fastened by the target user is in a comfortable position.

The first big data may be from a cloud, and the step 109 may be performed by the cloud, and the first image may be uploaded to the cloud by the VCU.

Wherein comparing the position information of the seat belt worn by the target user with the standard position information to determine whether the seat belt worn by the target user is in a comfortable position may specifically include: determining a degree of deviation of the position of the seatbelt worn by the target user from a standard position based on the position information of the seatbelt worn by the target user and the standard position information; when the deviation degree is smaller than a preset degree, determining that the safety belt tied on the target user is in a comfortable position; when the deviation distance is greater than or equal to a preset degree, determining that the safety belt worn by the target user is not in a comfortable position.

Generally, the position information of the seat belt worn by the target user mainly includes at least one of shoulder position information and abdomen position information, and correspondingly, the standard position information includes at least one of standard shoulder position information and standard abdomen position information. The degree of deviation may refer to at least one of deviation parameters such as a deviation distance from a standard position and a deviation angle.

Fig. 3A shows a schematic diagram of a standard position of a user wearing a safety belt of the same type as that of a target user, and as can be seen from fig. 3A, the standard position of the safety belt on the user of the above type includes: a standard shoulder position 31 and a standard abdomen position 32. The following describes how to determine whether or not the seat belt at these two locations is comfortable, with two embodiments.

One embodiment of the invention

The position information of the seatbelt worn by the target user includes shoulder position information, and the standard position information includes standard shoulder position information.

The comparing the position information of the seatbelt worn by the target user with the standard position information to determine whether the seatbelt worn by the target user is in a comfortable position may include: determining a deviation distance of the shoulder position of the safety belt fastened on the target user relative to the standard shoulder position based on the shoulder position information of the safety belt fastened on the target user and the standard shoulder position information; when the deviation distance is smaller than a first preset distance, determining that a safety belt of the shoulder of the target user is at a comfortable position; when the deviation distance is greater than or equal to the first preset distance, determining that the safety belt on the shoulder of the target user is not in the comfortable position.

The first preset distance can be set according to actual needs, for example, set to 2 cm.

The deviation distance of the shoulder position of the seatbelt fastened to the target user from the standard shoulder position may be a maximum deviation distance of the shoulder position of the seatbelt fastened to the target user from the standard shoulder position, as shown in d1 and d2 in fig. 3B and 3C. Fig. 3B and 3C show two schematic views of the target user wearing a harness in a non-comfortable position, respectively. Specifically, in FIG. 3B the shoulder position 34 of the belted target user is higher by d1cm relative to the standard shoulder position 31, and in FIG. 3C the shoulder position 35 of the belted target user is lower by d2cm relative to the standard shoulder position 31.

Alternatively, the comparing the position information of the seatbelt worn by the target user with the standard position information to determine whether the seatbelt worn by the target user is in the comfortable position may include: determining a deviation angle of the shoulder position of the safety belt fastened on the target user relative to the standard shoulder position based on the shoulder position information of the safety belt fastened on the target user and the standard shoulder position information; when the deviation angle is smaller than a first preset angle, determining that a safety belt of the shoulder of the target user is at a comfortable position; when the deviation angle is greater than or equal to a first preset angle, it is determined that the safety belt of the shoulder of the target user is not in the comfortable position.

The first preset angle may also be set according to actual needs, for example, set to 5 °.

The deviation angle of the shoulder position of the seatbelt worn by the target user with respect to the standard shoulder position may be an angle formed between the seatbelt of the shoulder of the target user and the seatbelt of the standard shoulder position, as shown by θ 1 and θ 2 in fig. 3B and 3C. Fig. 3B and 3C show two schematic views of the target user wearing a harness in a non-comfortable position, respectively. Specifically, in fig. 3B, the angle formed between the seat belt of the shoulder of the target user and the seat belt of the standard shoulder position is θ 1, and in fig. 3C, the angle formed between the seat belt of the shoulder of the target user and the seat belt of the standard shoulder position is θ 2.

Another embodiment

The position information of the safety belt worn by the target user comprises abdomen position information, and the standard position information comprises standard abdomen position information.

The comparing the position information of the seatbelt worn by the target user with the standard position information to determine whether the seatbelt worn by the target user is in a comfortable position may include: determining a deviation distance of the abdomen position of the safety belt fastened on the target user relative to the standard abdomen position based on the abdomen position information of the safety belt fastened on the target user and the standard abdomen position information; when the deviation distance is smaller than a second preset distance, determining that the safety belt of the abdomen of the target user is at a comfortable position; and when the deviation distance is greater than or equal to a second preset distance, determining that the safety belt on the abdomen of the target user is not in the comfortable position.

The second preset distance can be set according to actual needs, for example, set to 2 cm.

The deviation distance of the abdomen position of the safety belt fastened to the target user with respect to the standard abdomen position may be a maximum deviation distance of the abdomen position of the safety belt fastened to the target user with respect to the standard abdomen position, as D3 in fig. 3D. Fig. 3D shows another schematic view of the target user wearing a harness that is not in a comfortable position. Specifically, in fig. 3D, the belly position 33 of the belted belt on the target user is elevated D3cm relative to the standard belly position 32.

Alternatively, the comparing the position information of the seatbelt worn by the target user with the standard position information to determine whether the seatbelt worn by the target user is in the comfortable position may include: determining a deviation angle of the abdomen position of the safety belt fastened on the target user relative to the standard abdomen position based on the abdomen position information of the safety belt fastened on the target user and the standard abdomen position information; when the deviation angle is smaller than a second preset angle, determining that the safety belt of the abdomen of the target user is in a comfortable position; and when the deviation angle is larger than or equal to a second preset angle, determining that the safety belt on the abdomen of the target user is not in the comfortable position.

Wherein, the second preset angle can be set according to actual needs, such as 5 degrees.

The deviation angle of the abdominal position of the safety belt fastened to the target user with respect to the standard abdominal position may be an angle between the safety belt of the target user's abdomen and a tangent line at the intersection of the safety belt of the standard abdominal position, as θ 3 in fig. 3D. Fig. 3D shows another schematic view of the target user wearing a harness that is not in a comfortable position. Specifically, in fig. 3D, the angle between the tangent lines at the intersection of the safety belt 33 of the abdomen of the target user and the safety belt 32 of the standard abdomen position is θ 3.

And 110, controlling the target safety belt buckle to move towards or away from the backrest of the target seat so as to adjust the safety belt fastened on the target user to a comfortable position.

Specifically, when the seat belt worn by the target user is not in the comfortable position, in step 110, the deviation direction of the position of the seat belt worn by the target user with respect to the standard position may be determined based on the position information of the seat belt worn by the target user and the standard position information; determining a direction of movement of the target seatbelt buckle based on the direction of deviation; determining a target distance that the target seatbelt buckle moves based on the degree of deviation; controlling the target seatbelt buckle to move the target distance toward or away from a backrest of a target seat.

As shown in fig. 3B, based on the shoulder position information of the seatbelt fastened to the target user and the standard shoulder position information, it can be determined that the deviation direction of the shoulder position 34 of the seatbelt fastened to the target user with respect to the standard shoulder position 31 is high, the deviation distance is d1cm, and the deviation angle is θ 1, then it can be determined that the moving direction of the target seatbelt lock is the backrest away from the target seat based on the deviation direction of the shoulder position 34 with respect to the standard shoulder position 31, and the target distance is determined based on d1 and/or θ 1, and then, the target seatbelt lock is controlled to move the target distance away from the backrest of the target seat. For example, the target distance may be equal to d1, or may be converted into a more suitable distance, or may be determined by querying a preset correspondence table of the deviation distance and/or the deviation angle and the target distance, where the preset correspondence table may be determined experimentally in advance, or may be obtained through simulation (e.g., simulation in a three-dimensional vehicle assembly drawing) in advance.

As shown in fig. 3C, based on the shoulder position information of the seatbelt fastened to the target user and the standard shoulder position information, it can be determined that the deviation direction of the shoulder position 35 of the seatbelt fastened to the target user with respect to the standard shoulder position 31 is low, the deviation distance is d2cm, and the deviation angle is θ 2, then it can be determined that the moving direction of the target seatbelt buckle is toward the backrest of the target seat based on the deviation direction of the shoulder position 35 with respect to the standard shoulder position 31, and the target distance is determined based on d2 and/or θ 2, and then, the target seatbelt buckle is controlled to move toward the backrest of the target seat by the target distance. For example, the target distance may be equal to d2, or may be converted into a more suitable distance, or may be determined by querying a preset correspondence table of the deviation distance and/or the deviation angle and the target distance, where the preset correspondence table may be determined experimentally in advance, or may be obtained through simulation (e.g., simulation in a three-dimensional vehicle assembly drawing) in advance.

As shown in fig. 3D, based on the abdominal position information of the seatbelt fastened to the target user and the standard abdominal position information, it can be determined that the deviation direction of the abdominal position 33 of the seatbelt fastened to the target user with respect to the standard abdominal position 32 is high, the deviation distance is D3cm, and the deviation angle is θ 3, then it can be determined that the moving direction of the target seatbelt lock is the backrest away from the target seat based on the deviation direction of the abdominal position 33 with respect to the standard abdominal position 32, and the target distance is determined based on D3 and/or θ 3, and then, the movement of the target seatbelt lock away from the backrest of the target seat is controlled by the target distance. For example, the target distance may be equal to d3, or may be converted into a more suitable distance, or may be determined by querying a preset correspondence table of the deviation distance and/or the deviation angle and the target distance, where the preset correspondence table may be determined experimentally in advance, or may be obtained through simulation (e.g., simulation in a three-dimensional vehicle assembly drawing) in advance.

As can be seen from the three embodiments shown in fig. 3B, 3C and 3D, with this embodiment, when the shoulder position of the safety belt worn by the target user is higher than the comfortable position (the standard shoulder position), the target safety belt buckle can be moved a certain distance in the direction away from the backrest of the target seat, so as to adjust the safety belt on the shoulder of the target user to the comfortable position; when the shoulder position of the safety belt fastened on the target user is lower than the comfortable position (the standard shoulder position), moving the target safety belt lock catch towards the backrest direction of the target seat for a certain distance so as to adjust the safety belt on the shoulder of the target user to the comfortable position; when the belly position of the safety belt fastened on the target user is higher than the comfortable position (the standard belly position), the target safety belt lock catch is moved a certain distance away from the backrest direction of the target seat, so that the safety belt on the belly of the target user is adjusted to the comfortable position.

The safety belt buckle adjusting method provided by the embodiment shown in fig. 2 can solve the problems that a target user feels inconvenient and troublesome to operate when fastening a safety belt, and can automatically help users of different body types to find the most comfortable position of the safety belt in front of the user through an image recognition algorithm and big data comparison analysis, so that the trouble that the user needs to manually adjust the safety belt is further avoided.

Alternatively, as shown in fig. 2, in addition to the steps 102, 103, 104, 105, 107, 108, 109 and 110, another embodiment of the present application provides a seat belt buckle adjusting method, when the seat belt worn by the target user is in a comfortable position, the method may further include:

and 111, collecting the tension of the safety belt tied on the target user.

In specific implementation, the current tension of the safety belt can be detected through a force sensor in the target safety belt lock catch. In one example, the current amount of the tightening force of the safety belt is collected and uploaded to the cloud, and the cloud determines whether the tightening degree of the safety belt fastened by the target user is appropriate through the following step 112.

It can be understood that, the steps in the seat belt buckle adjustment method provided in the embodiment of the present application may be executed by one or more electronic devices, but not limited to one electronic device, for example, some steps may be executed by a cloud device.

Step 112, determining whether the tightness degree of the safety belt fastened by the target user is proper or not based on the tension of the safety belt fastened by the target user; if yes, go to step 106; otherwise, step 113 is performed.

Specifically, in step 112, the pulling force of the seat belt fastened by the target user may be compared with a preset pulling force, where the preset pulling force is obtained by analyzing second big data, the second big data includes seat belt pulling force data when the tightness degree of the seat belt worn by a plurality of users is appropriate, and the body types of the plurality of users are consistent with the body type of the target user; when the absolute value of the difference value between the pulling force of the safety belt tied on the target user and the preset pulling force is smaller than a preset threshold value, determining that the degree of tightness of the safety belt tied on the target user is proper; and when the absolute value of the difference value between the pulling force of the safety belt tied on the target user and the preset pulling force is greater than or equal to a preset threshold value, determining that the tightness degree of the safety belt tied on the target user is not appropriate.

The preset threshold may be set according to actual needs, and may be set to 2N, for example.

And 113, controlling the target safety belt lock to be lifted or lowered so as to adjust the tightness degree of the safety belt fastened by the target user.

The above-mentioned controlling the target seatbelt buckle to be raised or lowered includes controlling the target seatbelt buckle to be raised or lowered with respect to the seat surface.

Specifically, when the tightness degree of the safety belt fastened by the target user is inappropriate, the adjusting direction and the adjusting height of the target safety belt lock are determined based on the difference value between the pulling force of the safety belt fastened by the target user and the preset pulling force; controlling the target seatbelt buckle to raise or lower the adjustment height. More specifically, when the difference between the pulling force of the safety belt fastened by the target user and the preset pulling force is negative, it is indicated that the safety belt fastened by the target user is loose, and at this time, the lock catch of the target safety belt can be lowered to adjust the height, so that the safety belt fastened by the target user is tightened; when the difference value between the pulling force of the safety belt fastened by the target user and the preset pulling force is positive, the safety belt fastened by the target user is tight, and at the moment, the target safety belt lock catch can be lifted to adjust the height, so that the safety belt on the target user is loosened. The specific adjustment height is positively correlated with the absolute value of the difference.

Optionally, after one adjustment, the process returns to step 112, and the process is repeated in this way until the tightness of the safety belt worn by the target user is properly adjusted.
