Description

Technical Field

[0001] This invention relates to the field of vehicle safety seats, and more particularly to a method for controlling a child safety seat, a system for controlling a child safety seat, and a computer program product for at least assisting in implementing the steps of the method according to the invention. Background Technology

[0002] With the increasing prevalence of private vehicles, regulations regarding child passenger safety are receiving more and more attention. Currently, legislation mandates that children under four years old must use child safety seats when traveling in a car. However, the market offers a wide variety of child safety seats, and there are no unified standards for their installation and use. For example, questions such as whether child safety seats should be installed front-facing or rear-facing, whether the headrest height is appropriate, and whether objects around the child safety seat could cause secondary injuries during a collision pose significant difficulties and challenges in their practical use.

[0003] Therefore, how to make child safety seats both compliant with safety regulations and user-friendly to control has become a technical challenge that needs to be addressed. Summary of the Invention

[0004] The object of the present invention is to provide a method for controlling a child safety seat, a system for controlling a child safety seat, and a computer program product for at least assisting in implementing the steps of the method according to the present invention, so as to at least partially solve the problems in the prior art.

[0005] According to a first aspect of the present invention, a method for controlling a child safety seat is provided, the method comprising the following steps:

[0006] - Obtain the identity information of the occupants in the child safety seat;

[0007] - Detect vehicle operating condition information during vehicle operation; and

[0008] - Incorporate the occupant's identity information and / or the driving condition information as control factors to adjust and / or prompt the child safety seat's posture parameters.

[0009] The core concept of this invention lies in adjusting and / or prompting various positional parameters of the child safety seat according to the occupant's identity information and / or vehicle driving conditions. According to this invention, by controlling the child safety seat in a safety-compliant and user-friendly manner, the safety of occupants in vehicles can be effectively improved, especially in cases of vehicle collisions, rapid acceleration, sharp turns, or emergency cornering, where it can mitigate physical injury to the occupant.

[0010] According to an optional embodiment of the present invention, the occupant's identity information can be obtained through the perception and fusion results of the vehicle-mounted camera and / or the detection results of the pressure sensor arranged in the child safety seat. The occupant's identity information may include, for example, the occupant's height, weight, and / or age.

[0011] According to another optional embodiment of the present invention, by incorporating the occupant's identity information and / or the driving condition information as control factors, the orientation of the child safety seat can be adjusted via a planetary gear mechanism. Optionally, when the occupant in the child safety seat needs to get in or out of the vehicle, the orientation of the child safety seat can be adjusted to face outwards relative to the vehicle body. Optionally, if the vehicle speed is higher than a preset speed threshold and the occupant's identity information is lower than a preset identity information threshold, the orientation of the child safety seat can be adjusted to face backwards relative to the vehicle body; otherwise, the orientation of the child safety seat can be adjusted to face forwards relative to the vehicle body. In this way, the high load and large transmission ratio characteristics of the planetary gear mechanism can be fully utilized, and the orientation of the child safety seat can be dynamically and automatically controlled at any angle based on actual needs, thereby providing the most suitable sitting posture for the occupant in the child safety seat, improving the occupant's riding safety, and also facilitating other occupants in the vehicle to take care of the occupant in the child safety seat, thereby improving the occupant's riding comfort.

[0012] According to another optional embodiment of the present invention, it can be determined whether the headrest height of the child safety seat is suitable for the occupant's height, and if it is not suitable, a corresponding prompt message can be sent, so that other occupants in the vehicle can manually adjust the headrest height to a suitable position for the occupant. Optionally, if it is not suitable, the headrest height can also be automatically adjusted to a suitable position based on the occupant's identity characteristics, especially height, for example, through a gear and rack mechanism.

[0013] According to another optional embodiment of the present invention, it can be determined whether the tension of the webbing of the child safety seat is adapted to the occupant's identity information and / or the driving condition information, and if it is not adapted, it can send optical and / or acoustic prompts about the need to adjust the tension of the webbing. Optionally, the tension of the webbing of the child safety seat can also be automatically adjusted by a webbing electric rewind mechanism, thereby avoiding other occupants in the vehicle from manually tightening the webbing for the occupant, and preventing the occupant from being thrown out of the child safety seat due to the mismatch of the webbing tension in the event of a vehicle collision.

[0014] According to another optional embodiment of the present invention, in the event of a vehicle collision, the occupant's identity information and / or the driving condition information can be incorporated as control factors to adjust the force-limiting level of the force-limiting restraint mechanism of the child safety seat. The force-limiting restraint mechanism, in particular the force-limiting bar, can be tightened according to a force-limiting level calculated based on the occupant's identity information (especially weight), the detected driving speed, and / or driving acceleration, thereby mitigating injuries to the occupant's body, especially the chest, during a vehicle collision.

[0015] According to another optional embodiment of the present invention, in the event of a vehicle collision, front seat pressure information and / or child seat acceleration information can also be introduced as influencing factors to predict the injury status of the occupant and send a prompt message about the predicted injury status. The front seat pressure information particularly includes pressure information of the backrest area of ​​the front seat. Based on the front seat pressure information, it can be determined whether the occupant's head and / or the child safety seat came into contact with the front seat, especially the backrest area of ​​the front seat, during the vehicle collision.

[0016] According to another optional embodiment of the present invention, it can be determined whether the distance between the child safety seat and surrounding objects, especially the front seats, is suitable for the occupant's identity information and / or the driving condition information, and send corresponding prompt information if they are not suitable. In this way, it is possible to avoid hard contact between the occupant in the child safety seat and surrounding objects when the vehicle is performing operations such as turning, braking, or acceleration, or even in the event of a vehicle collision.

[0017] According to another optional embodiment of the present invention, the method may further include the following steps:

[0018] - Determine whether the category of the child safety seat is appropriate for the occupant's identity information;

[0019] - If it is not suitable, a prompt message will be sent regarding replacing the child safety seat.

[0020] According to a third aspect of the present invention, a system for controlling a child safety seat is provided, the system being used to perform the method according to the present invention. The system may include the following components:

[0021] -Identity information recognition module, which is configured to acquire the identity feature information of the occupant in the child safety seat;

[0022] - Driving condition detection module, which is configured to detect the driving condition information of the vehicle during vehicle operation;

[0024] - A seat control module, configured to adjust the posture parameters of the child safety seat based on the calculated posture parameters, wherein the seat control module may include, for example, a planetary gear mechanism, a webbing electric rewind mechanism and / or a force limiting restraint mechanism, etc.

[0025] and

[0026] - A prompting module configured to send prompts regarding the calculated posture parameters of the child safety seat.

[0037] To make the technical problems to be solved, the technical solutions, and the beneficial technical effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of protection of this invention.

[0038] Figure 1 A flowchart illustrating a method for controlling a child safety seat according to an exemplary embodiment of the present invention is shown. The following exemplary embodiments describe the method according to the present invention in more detail.

[0039] The method may include steps S1 to S3. In step S1, the identity feature information of the occupant in the child safety seat is obtained. In the current embodiment of the invention, the occupant's identity feature information can be obtained through the perception and fusion results of the vehicle-mounted camera. For example, the occupant's height, weight, and / or age can be obtained by image processing of images of the occupant in the child safety seat captured by the vehicle-mounted camera, wherein the age information can be predicted based on the occupant's height, weight, and / or facial feature information. Alternatively, the occupant's facial feature information can be extracted and the corresponding pre-stored identity feature information, including the occupant's height, weight, and / or age, can be retrieved from the vehicle controller or backend server based on the extracted facial feature information. It is understood that the identity feature information of the family member's children can be stored in family vehicles. Optionally, the occupant's weight information can also be obtained through the detection results of pressure sensors arranged in the child safety seat.

[0040] In step S2, the vehicle's driving condition information is detected during vehicle operation. This driving condition information may include, for example, the vehicle speed detected by an onboard speed sensor, the vehicle acceleration detected by an onboard acceleration sensor, and optionally, the door opening / closing status detected by a door sensor, which can be used to assist in determining the occupants' intention to get on / off the vehicle.

[0041] In step S3, the occupant's identity information and / or the driving condition information are introduced as control factors to adjust and / or prompt the child safety seat's posture parameters. The child safety seat's posture parameters may include, for example, the child safety seat's orientation. Considering the high load and large transmission ratio characteristics of the planetary gear mechanism, the orientation of the child safety seat can be adjusted through the planetary gear mechanism. The following is combined with... Figure 2 The orientation adjustment of a child safety seat is illustrated by another exemplary embodiment of the invention. The following description only addresses the... Figure 1 The differences between the embodiments shown are omitted for brevity, and the same steps will not be repeated.

[0042] Step S3 may include steps S311 to S315. In step S311, it is determined whether the occupant in the child safety seat needs to get in or out of the vehicle. Here, the occupant's actions can be identified based on image processing of in-vehicle image information captured by the vehicle's in-vehicle camera, thereby identifying the occupant's intention to get in / out of the vehicle. Alternatively, it can be determined based on the detection results of the door sensor and the vehicle's speed sensor; for example, when the vehicle speed is zero and the door near the child safety seat is open, the occupant's intention to get in / out can be identified.

[0043] When the occupant of the child safety seat needs to get in or out of the vehicle, in step S312, the orientation of the child safety seat can be adjusted to face outward relative to the vehicle body by means of the child safety seat chassis driven by the planetary gear mechanism, so that other occupants can conveniently and effortlessly carry the child from outside the vehicle into the child safety seat or carry the child safety seat out of the vehicle.

[0044] When the occupant of the child safety seat does not need to get in or out of the vehicle, step S313 can determine whether the vehicle speed is higher than a preset speed threshold (e.g., 30 km / h) and whether the occupant's identity information is lower than a preset identity information threshold, such as a height threshold of 105 cm or an age threshold of 4 years old. If the vehicle speed is higher than the preset speed threshold and the occupant's identity information is lower than the preset identity information threshold, step S314 can adjust the orientation of the child safety seat relative to the vehicle body to rearward using the child safety seat chassis driven by a planetary gear mechanism. Considering that younger children have a larger proportion of head weight and a more fragile cervical spine, this not only protects the occupant's head but also reduces the risk of cervical spine injury due to forward head tilting during vehicle movement. If the above conditions are not met, i.e., the vehicle speed is higher than the preset speed threshold or the occupant's identity information is lower than the preset identity information threshold, step S315 can adjust the orientation of the child safety seat relative to the vehicle body to forward using the child safety seat chassis driven by a planetary gear mechanism.

[0045] In this way, the orientation of the child safety seat can be dynamically and automatically controlled at any angle based on actual needs, thereby providing the most suitable sitting posture for the occupant and improving the occupant's safety. At the same time, it also helps other passengers in the vehicle to take care of the occupant in the child safety seat, thereby improving the occupant's comfort.

[0046] Optionally, the positional parameters of the child safety seat may also include, for example, the headrest height of the child safety seat. (The following is in conjunction with...) Figure 3 The following illustration demonstrates the headrest height adjustment of a child safety seat according to another exemplary embodiment of the invention. Only the following description relates to... Figure 1 The differences between the embodiments shown are omitted for brevity, and the same steps will not be repeated.

[0047] Step S3 may further include steps S321 to S322. In step S321, it is determined whether the headrest height of the child safety seat is suitable for the occupant's height. If the headrest height of the child safety seat is not suitable for the occupant's height, then in step S322, a corresponding prompt message is sent. For example, an optical and / or acoustic prompt message regarding the need to adjust the headrest height can be sent through the vehicle's voice device, central control display screen, instrument panel, and / or indicator lights, so that other occupants in the vehicle can manually adjust the headrest height to a suitable position for the occupant. Optionally, in step S322, the headrest height can also be automatically adjusted to a suitable position based on the occupant's identity characteristics, especially height, for example, through a rack and pinion mechanism.

[0048] Optionally, the positional parameters of the child safety seat may also include, for example, the tension of the child safety seat's webbing. (The following is in conjunction with...) Figure 4 The following illustration demonstrates the adjustment of the webbing tension of a child safety seat according to another exemplary embodiment of the present invention. Only the following description relates to... Figure 1 The differences between the embodiments shown are omitted for brevity, and the same steps will not be repeated.

[0049] Step S3 may further include steps S331 to S332. In step S331, it is determined whether the tension of the child safety seat's webbing is appropriate for the occupant's identity information and / or the driving condition information. It is understood that during severe braking or a collision, the occupant in the child safety seat will move violently forward due to inertia. A loose webbing may cause the occupant to fall out of the child safety seat, while an overly tight webbing may cause injury to the occupant's shoulder, damage to internal organs by digging into the abdomen, or strangle the neck, leading to suffocation and fainting. Therefore, the appropriateness of the current webbing tension of the child safety seat can be determined based on the occupant's height, weight, vehicle speed, and / or acceleration.

[0050] If the webbing tension of the child safety seat is not adapted to the occupant's identity information and / or the driving condition information, a corresponding prompt message can be sent in step S332. For example, optical and / or acoustic prompt messages about the need to adjust the webbing tension can be sent through in-vehicle voice equipment, central control display screen, instrument panel and / or indicator lights. Alternatively, the webbing tension of the child safety seat can be automatically adjusted through an electric webbing retraction mechanism, thereby avoiding other occupants in the vehicle from manually tightening the webbing for the occupant and preventing the occupant from being thrown out of the child safety seat due to the mismatch in webbing tension in the event of a vehicle collision.

[0051] Optionally, the positional parameters of the child safety seat may also include, for example, the force-limiting level of the force-limiting restraint mechanism of the child safety seat. (The following is in conjunction with...) Figure 5 The adjustment of the force-limiting level of the force-limiting restraint mechanism of a child safety seat is illustrated by another exemplary embodiment of the present invention. The following only describes the adjustment of the force-limiting restraint mechanism. Figure 1 The differences between the embodiments shown are omitted for brevity, and the same steps will not be repeated.

[0052] Step S3 may further include steps S341 to S342. In step S341, it is determined whether a collision has occurred. Here, the collision situation can be predicted by the vehicle's acceleration or detected by the vehicle's collision sensors. If a collision has occurred, in step S342, the occupant's identity information and / or the driving condition information are introduced as control factors to adjust the force limiting level of the child safety seat's force restraint mechanism. The force restraint mechanism, especially the force limiting bar, can be tightened according to the force limiting level calculated based on the occupant's identity information (especially weight), the detected driving speed, and / or driving acceleration, thereby mitigating the injury to the occupant's body, especially the chest, during a collision.

[0053] Optionally, step S3 may further include step S343. In step S343, front seat pressure information and / or child seat acceleration information are also introduced as influencing factors to predict the occupant's injury status and send a prompt message regarding the predicted injury status. Here, the occupant's head injury status can be predicted based on pressure information of the front seat back area detected by, for example, a pressure sensor located in the back area of ​​the front seat, to identify whether the occupant made hard contact with the back area of ​​the front seat during a vehicle collision. The pressure experienced by the occupant during a vehicle collision can also be analyzed based on child seat acceleration information detected by an acceleration sensor located in the child safety seat, thereby predicting the probability of the occupant's head and chest injury levels. Understandably, during a vehicle collision, a child safety seat occupant will be violently thrown forward due to inertia. The webbing on the occupant's body could potentially strangle the shoulder, penetrate the abdomen causing internal organ damage, or strangle the neck, leading to suffocation and unconsciousness. The occupant's head may also make hard contact with surrounding objects, especially the backrest area of ​​the front seat. After a collision, the predicted injury status of the occupant can be sent to other occupants via the vehicle's voice system, central control display, and / or dashboard, thus buying valuable time for rescue.

[0054] Optionally, the positional parameters of the child safety seat may also include, for example, the distance between the child safety seat and surrounding objects, especially the front seats. The following, in conjunction with... Figure 6 The invention will be illustrated in detail with reference to another exemplary embodiment. The following description only addresses... Figure 1 The differences between the embodiments shown are omitted for brevity, and the same steps will not be repeated.

[0055] Step S3 may further include steps S351 to S352. In step S351, it is determined whether the distance between the child safety seat and surrounding objects, especially the front seat, is appropriate to the occupant's identity information and / or the driving condition information. Here, the distance between the child safety seat and surrounding objects, especially the front seat, can be detected based on image processing of in-vehicle image information collected by the vehicle's camera, and it is determined whether the distance is appropriate to, for example, the occupant's height, vehicle speed, and / or acceleration. It is understood that too small a distance may cause the occupant in the child safety seat to make hard contact with surrounding objects when the vehicle performs turning, braking, acceleration, or even in the event of a collision.

[0056] If the distance is not compatible with the occupant's identity information and / or driving conditions, a corresponding prompt message will be sent. For example, optical and / or acoustic prompt messages will be sent through in-vehicle voice devices, central control displays, instrument panels and / or indicator lights regarding the need to adjust the distance between the child safety seat and surrounding objects, especially the distance with the front seats, so as to minimize the risk of collision between the occupant in the child safety seat and surrounding objects.

[0057] According to embodiments of the present invention, various positional parameters of the child safety seat can be adjusted and / or prompted based on the occupant's identity information and / or vehicle driving conditions, thereby effectively improving the safety of the occupant in the child safety seat, especially in cases of vehicle collision, violent acceleration, sharp turns or emergency turns, which can reduce the physical injury to the occupant.

[0058] Figure 7 A flowchart illustrating a method for controlling a child safety seat according to another exemplary embodiment of the present invention is shown.

[0059] The method may further include steps S11 and S12. In step S11, it is determined whether the category of the child safety seat is compatible with the occupant's identity information. In an optional embodiment of the present invention, the category information of the child safety seat can be obtained by identifying information codes (including barcodes, QR codes, feature codes, etc.) on the child safety seat; alternatively, the category information can be obtained based on image processing of images of the child safety seat captured by an in-vehicle camera. Considering that the child safety seats may be divided into multiple categories, for example, according to age, weight, and / or height, only a child safety seat that is compatible with the occupant's age, weight, and / or height can ensure the occupant's safety while traveling.

[0060] If the category of the child safety seat is not compatible with the occupant's identity information, then in step S12, a prompt message regarding replacing the child safety seat may be sent, for example, through an in-vehicle voice device, a central control display screen, an instrument panel, and / or indicator lights.

[0061] Additionally, it should be noted that the step numbers described herein do not necessarily represent a sequential order, but are merely a reference numeral. The order may be changed depending on the specific circumstances, as long as the technical objective of the present invention can be achieved.
