Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a vehicle seat belt adjustment method, a vehicle and a readable storage medium. Background Art

[0002] Vehicle seat belts are the most important safety protection equipment on a vehicle. They can ensure the safety of drivers and passengers to a great extent when the vehicle collides. However, vehicle seat belts are mostly designed based on adult requirements. Drivers and passengers with small stature in the back seat may feel their necks strangled when using seat belts, and it is not easy to insert the seat belt into the latch.

[0003] In the related art, the driver and passengers can manually adjust the height of the vehicle seat belt through the up and down buttons on the safety column, that is, turn the adjustment button on the safety column and adjust the height of the slide plate, thereby driving the vehicle seat belt to move up and down. The user can adjust the seat belt height to a suitable position according to his or her own situation and insert the seat belt insert into the pin fixed on the seat.

DETAILED DESCRIPTION

[0085] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0086] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0087] Traditional vehicle seat belts are designed based on adult requirements. For small passengers, the seat belts may cause strangulation of the neck. Passengers can manually adjust the height of the vehicle seat belts through the up and down buttons on the safety column, that is, turn the adjustment button on the safety column and adjust the height of the slide plate to drive the vehicle seat belt to move up and down. Users can adjust the seat belt height to a suitable position according to their own situation and insert the seat belt insert into the pin fixed on the seat.

[0088] Therefore, the related art lacks a method for adjusting the height of the safety point. The seat belt height is manually adjusted and the seat belt insert is inserted into the pin fixed on the seat, resulting in a low level of vehicle automation, making it difficult to meet the needs of drivers and passengers of different body shapes, thereby reducing the riding experience of drivers and passengers.

[0089] Next, the application scenario or system architecture of the embodiment of the present application will be schematically described. Figure 1 The vehicle safety belt adjustment system includes a shoulder height detection member 100, a first adjustment member 200, a second adjustment member 300 and a controller 400. The shoulder height detection member 100 detects the actual height of the user's shoulder, and the first adjustment member 200 can adjust the Figure 2 The second adjusting member 300 adjusts the angle between the vehicle seat belt outlet 1 and the vehicle seat, and when the user uses the vehicle seat belt, the controller 400 controls the second adjusting member 300 to adjust the angle to the optimal angle, and controls the first adjusting member 200 to adjust the vertical height to the target height corresponding to the actual height.

[0090] In some embodiments, the shoulder height detection component 100 in the embodiment of the present application can be provided with at least one camera to collect the shoulder image of the user, and can also be provided with an identification component to identify the actual height of the user's shoulder according to the shoulder image. Figure 3 and Figure 4 As shown, a lifting motor 201 and a height adjuster 2 can be set by a first adjusting member 200, and a part of the height adjuster 2 can be driven by the lifting motor 201 to move up and down relative to the user's shoulder, so that the belt outlet 1 of the vehicle seat belt can be adjusted to a position suitable for use by the driver and passengers, wherein the position of the seat belt can be fixed by a seat belt retractor guide ring, the first adjusting member 200 is 15 mm higher than the human shoulder, the adjustment stroke is 196 mm in total, and the height adjuster has an upper limit 3 and a lower limit 4.

[0091] like Figure 4 As shown, the first adjustment member 200 can be provided with at least one slide plate cylindrical protrusion 5, which is movably matched with the longitudinal guide rail 6, and the slide plate cylindrical protrusion 5 and the longitudinal guide rail 6 are matched, wherein the matching gap is 0.1 mm, combined with Figure 5 and Figure 6As shown, the second adjustment member 300 can be provided with a rotating motor 7 to drive the latch 8 to rotate, and the controller 400 controls the rotating motor 7 to drive the latch 8 to rotate according to the waist circumference data of the driver and the occupant, so that the angle between the latch 8 of the seat belt and the seat 10 is rotated to a certain angle. In addition, when the latch 8 of the seat belt rotates, a limit mechanism is designed at the upper and lower limit 9 positions of the latch 8, and the rotation angle is 50-60 degrees to meet the rotation angle adjustment requirements, thereby facilitating the insertion of the seat belt insert 11. When the user uses the vehicle seat belt, the controller 400 controls the second adjustment member 300 to adjust the angle to a certain angle, and controls the first adjustment member 200 to adjust the vertical height to a target height corresponding to the actual height according to the shoulder height of the user. In addition, as Figure 7 As shown, the user can manually adjust the vehicle seat belt according to the height adjustment button 12, so as to adjust the vehicle seat belt to a target protection posture.

[0092] Figure 8 It is a schematic flow chart of a vehicle seat belt adjustment method provided in an embodiment of the present application.

[0093] For example, Figure 8 As shown, the method comprises the following steps:

[0094] In step S801, at least one body parameter of the driver or passenger is obtained.

[0095] In the embodiment of the present application, at least one body shape parameter refers to some user parameters related to the user when using the vehicle seat belt, so as to be more targeted to the user, which will be introduced with examples below.

[0096] In addition, there are many ways to obtain body shape parameters, and the vehicle seat belts can be adaptively adjusted based on the body shape parameters, thereby improving the feasibility of the vehicle seat belt adjustment.

[0097] The embodiment of the present application can obtain at least one body parameter of the driver and passenger in the following steps, thereby improving the feasibility of adjusting the vehicle seat belts, increasing the accuracy of adjusting the vehicle seat belts, and improving the safety of the driver and passenger.

[0098] Among them, in one embodiment of the present application, obtaining at least one body parameter of the driver and passenger includes: detecting the actual intention of the driver and passenger outside the vehicle; when the actual intention is to get on the vehicle, obtaining a user image of the driver and passenger; extracting at least one body feature of the user image, and obtaining at least one body parameter based on the at least one body feature.

[0099] Here, an example is given to describe the acquisition method. For example, the embodiment of the present application can detect the actual intention of the driver and passenger outside the vehicle in the following steps, and when the actual intention is the intention to ride, the user image of the driver and passenger is obtained, such as the user image of the driver and passenger can be obtained through the camera outside the vehicle, and the relative features of the driver and passenger relative to the vehicle window, or the height features of the driver and passenger's shoulders and the ground in the user image are extracted, and the body parameters of the driver and passenger, such as actual height, shoulder height, etc., are obtained to adjust the seat belt based on the actual height and shoulder height, thereby effectively improving the accuracy of the vehicle seat belt adjustment, so that the vehicle seat belt presents a better protection posture, improves the safety and use experience of the driver and passenger, avoids the phenomenon that strangling the neck is equal to body discomfort, and improves the intelligence level of the vehicle.

[0100] For another example, the embodiments of the present application can determine the actual distance between the user and the vehicle through an infrared ranging sensor, and detect whether the actual state of the door is open or closed. When the actual distance between the user and the vehicle is less than 0.2 meters, and the actual state of the door is open, the user outside the vehicle is determined to be a passenger who wants to board the vehicle. Therefore, the vehicle can adjust the vehicle seat belts in advance according to the body characteristics of the passenger before the passenger gets on the vehicle, without the need for the user to make adaptive adjustments after boarding, effectively improving the user's driving experience.

[0101] Optionally, in one embodiment of the present application, after adjusting the vehicle seat belt according to the at least one adjustment parameter, it also includes: receiving an adjustment instruction from the driver; obtaining a user adjustment parameter of the vehicle seat belt according to the adjustment instruction, and adjusting the vehicle seat belt according to the user adjustment parameter.

[0102] In the embodiment of the present application, the adjustment instruction is an instruction actively issued by the driver and passenger, which can be issued manually by the driver and passenger through physical buttons, or issued by the driver and passenger through voice, and no specific limitation is made here.

[0103] During the actual implementation process, the embodiments of the present application can receive adjustment instructions from the driver and passengers. For example, the driver and passengers can adjust the height of the seat belt outlet through the up and down buttons of the physical buttons. During manual adjustment, the drive motor adopts a stepless drive and can stop at any position within the adjustment range. The driver and passengers can manually rotate the angle of the seat belt pin to adjust the seat belt to a comfortable position. Alternatively, the driver can use voice to say "Hello, XX car, please adjust the rear right side outlet upwards by 1 cm and rotate the pin 55 degrees". The vehicle can control the height of the vehicle's seat belt outlet and the rotation angle of the pin according to the adjustment instructions of the driver and passengers, effectively improving the interactivity of the vehicle and enhancing the user's driving experience.

[0104] Optionally, in one embodiment of the present application, obtaining at least one body parameter of the driver and occupant includes: collecting the actual load-bearing capacity of the vehicle seat; when the actual load-bearing capacity is greater than a preset threshold, identifying the body shape of the driver and occupant, and determining at least one body parameter based on the body shape.

[0105] Different from the above-mentioned embodiment in which the vehicle seat belt is adjusted in advance, the embodiment of the present application performs adaptive adjustment of the seat belt after detecting that a user is sitting, which is described below with an example.

[0106] For example, the embodiment of the present application can collect the actual load-bearing capacity of the vehicle seat through a weight sensor. When the actual load-bearing capacity of the vehicle seat is greater than 15kg, it is determined that there is a user riding in the vehicle. The camera in the vehicle can start to identify the body shape of the driver and passenger, and determine the body parameters of the driver and passenger based on the body shape, such as actual height, shoulder height, actual weight, etc., so as to perform adaptive adjustment of the seat belt, effectively improving the accuracy of the vehicle seat belt adjustment and improving the safety of the user's driving.

[0107] It should be noted that the preset threshold is set by those skilled in the art according to actual conditions and is not specifically limited here.

[0108] In step S802, a target protection posture of a vehicle safety belt is matched according to at least one body shape parameter.

[0109] In the embodiments of the present application, users of different body shapes use different adapted seat belts, thereby defining the target protection posture of the vehicle seat belt, such as but not limited to the height of the seat belt and the rotation angle of the latch, so that the vehicle seat belt presents different protection postures.

[0110] The embodiments of the present application can match different seat belt protection postures according to different body shapes, thereby improving the protection of vehicle seat belts, enhancing the intelligence level of the vehicle, and improving the user's driving experience.

[0111] In step S803, at least one adjustment parameter of the vehicle seat belt is determined according to the target protection posture and the current protection posture or initial protection state of the vehicle seat belt, and the vehicle seat belt is adjusted according to the at least one adjustment parameter to be in the target protection posture.

[0112] In the embodiments of the present application, the initial protection state can be understood as the default protection posture of the seat belt, which can be pre-set by the manufacturer or set by the user. The current protection posture can be understood as a protection posture that has not been restored to the initial protection state, such as the protection posture of the seat belt when used by the previous user.

[0113] It can be understood that the embodiment of the present application can determine at least one adjustment parameter of the vehicle seat belt based on the target protection posture in the following steps and the current protection posture or initial protection state of the vehicle seat belt, and adjust the vehicle seat belt according to the at least one adjustment parameter to be in the best protection posture, that is, a safe and comfortable protection posture, thereby effectively improving the vehicle's automation level, meeting the needs of drivers and passengers of different body shapes, and improving the user's driving experience.

[0114] Among them, in one embodiment of the present application, at least one adjustment parameter of the vehicle seat belt is determined according to the target protection posture and the current protection posture or initial protection state of the vehicle seat belt, including: determining the height adjustment value of the vehicle seat belt outlet and the rotation adjustment value of the latch according to the target protection posture and the current protection posture, respectively.

[0115] At least one adjustment parameter is described herein. The adjustment parameter may be, but is not limited to, a height adjustment value of the belt outlet of the safety belt and a rotation adjustment value of the latch, which may be set by those skilled in the art according to an implementable manner of the safety belt and is not specifically limited herein.

[0116] For example, based on the seat belt system architecture of the above-mentioned embodiment, the embodiment of the present application can determine the vertical height of the vehicle seat belt outlet relative to the shoulder of the driver and occupant according to the actual height, shoulder height, actual weight and other body parameters of the driver and occupant, adjust the height of the vehicle seat belt outlet to a height suitable for the driver and occupant, and adjust the rotation adjustment value of the seat belt pin according to the waist circumference data of the driver and occupant, so that the angle between the seat belt pin and the seat is adjusted to the optimal angle, that is, the most comfortable angle for the driver and occupant, thereby facilitating the insertion of the seat belt insert, effectively improving the accuracy of the vehicle seat belt adjustment, and improving the convenience of user driving.

[0117] For another example, based on the seat belt system architecture of the above-mentioned embodiment, the cylindrical protrusion of the slide plate in the vehicle seat belt can cooperate with the movement of the longitudinal guide rail to control the adjustment of the height of the seat belt outlet, and can also obtain the abdominal circumference data of the driver and occupant. For example, a camera installed on the inside of the vehicle door can be used to take a picture of the driver and occupant's abdomen, and the abdominal circumference data can be obtained based on the occluded shadows in the picture. The rotation value of the seat belt pin driven by the rotating motor can be controlled according to the abdominal circumference data, so that the angle between the seat belt pin and the seat is adjusted to the optimal angle, thereby facilitating the insertion of the seat belt insert and improving the user's driving safety.

[0118] Optionally, in one embodiment of the present application, before obtaining at least one body parameter of the driver or passenger, it also includes: obtaining the identity of the driver or passenger; determining whether the vehicle stores a target protection posture corresponding to the identity; if the target protection posture is stored, adjusting the vehicle seat belt to enter the target protection posture, otherwise obtaining at least one body parameter.

[0119] In the embodiments of the present application, the identity identification refers to the user identity, which can be obtained by acquiring the facial image of the driver or passenger through the in-vehicle camera, or can be obtained through the user's voiceprint information, fingerprint information, etc., without specific limitation here.

[0120] In some embodiments, the embodiments of the present application can obtain facial images of the driver and occupants through the in-vehicle camera, and determine whether the vehicle database stores the target protection posture corresponding to the driver and occupants based on the facial images. When the target protection posture is stored, the vehicle seat belts are adjusted to the target protection posture without collecting body shape parameters, and can be directly retrieved to reduce redundant operations. Otherwise, the body shape parameters of the driver and occupants are obtained through the in-vehicle camera, and the vehicle seat belts are adjusted to the target protection posture based on the body shape parameters.

[0121] It can be understood that the embodiment of the present application can obtain the facial image of the driver or passenger through the in-vehicle camera when the driver or passenger gets on the vehicle for the first time. When the vehicle seat belt is adjusted to the optimal protection posture according to the body parameters of the driver or passenger, the optimal protection posture corresponding to his or her identity identification is stored after the memory function is triggered. This allows the vehicle seat belt to directly adjust the seat belt height and the rotation angle of the pin to the optimal position according to the driver or passenger's identity identification when the driver or passenger gets on the vehicle next time, effectively improving the intelligence level of the vehicle and enhancing the user's driving experience.

[0122] Optionally, in one embodiment of the present application, it also includes: detecting whether the driver and passenger meet the preset getting off conditions; when it is detected that the driver and passenger meet the preset getting off conditions, determining the adjustment mode of the vehicle seat belt; when the adjustment mode is the memory mode, controlling the vehicle seat belt to maintain the target protection posture as the current protection posture; when the adjustment mode is the return mode, controlling the vehicle seat belt to return to the initial protection state.

[0127] In some embodiments, the embodiments of the present application can receive setting instructions from the driver and passengers. For example, the driver can adjust the rear right seat belt of the vehicle to the memory mode through a physical button, or the driver can use voice to say "Hello, XX car, please adjust the rear right seat belt to the return mode". The vehicle can then control the vehicle seat belt to be in the memory mode or the return mode according to the setting instructions of the driver and passengers, effectively improving the interactivity of the vehicle and enhancing the user's driving experience.

[0128] In summary, the present application can match the best protection state of the vehicle seat belt according to the body parameters of the driver and passenger, and determine the adjustment parameters of the seat belt, so as to adjust the seat belt to the best protection posture according to the adjustment parameters, effectively improve the automation level of the vehicle, meet the needs of drivers and passengers of different body types, and improve the user's driving experience. Thus, the problem of manually adjusting the seat belt height in the related art, which leads to a low level of vehicle automation, inconvenient operation, inability to meet the needs of drivers and passengers of different body types, and reduced driving experience of drivers and passengers, etc., is solved.
