Description

Technical Field

[0001] This application relates to the field of automotive technology, and more particularly to the field of automotive seat belt technology, specifically to a vehicle seat belt control method, device, equipment, and storage medium. Background Technology

[0002] Today, with the development of society and economy, the number of cars is increasing day by day, and people's safety awareness is constantly improving. Faced with complex and ever-changing road conditions, the safety performance of cars is also being given more and more attention. As an important part of the occupant restraint system, when the vehicle is under emergency braking or a collision occurs, the seat belt can fix the occupants to the seat through active pretensioning or passive pretensioning, protecting the lives of the driver and passengers.

[0003] Currently, most car seat belts with active pretensioners are designed and installed based entirely on the skeletal strength of adults, without considering the situation of child seats. If a child seat is installed in a car, the active seat belt will actively pretension during emergency braking. The occupant's body will be thrown forward due to inertia, and their bones and muscles will bear the restraining force exerted by the seat belt. The restraining force that a child can withstand is different from that that an adult male can withstand. If the active pretensioning force of the seat belt is too high, vulnerable groups such as children may experience discomfort due to excessive restraint, potentially causing secondary injuries, posing a certain safety risk.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0025] Furthermore, it should be noted that the collection, storage, use, processing, transmission, provision, and disclosure of relevant data such as the seat belt usage status and current tension in the technical solution of this application all comply with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0026] Example 1

[0027] Figure 1 This is a flowchart of a vehicle seat belt control method according to Embodiment 1 of this application. This embodiment is applicable to situations where the passenger's seat belt is actively pre-tensioned during vehicle operation. This can be performed by a vehicle seat belt control device, which can be implemented in hardware and / or software. The vehicle seat belt control device can be configured in a computer device, such as a server.

[0028] like Figure 1 As shown, the method includes:

[0029] S110. Based on the current seat belt usage status of the candidate seat belts in the vehicle, determine the target seat belt from the candidate seat belts and determine the target seat corresponding to the target seat belt.

[0030] In this context, "candidate seatbelts" refers to all seatbelts currently in the vehicle. Seatbelt usage status indicates whether a candidate seatbelt is currently in use. "Target seatbelt" refers to the seat currently being used. "Target seat" refers to the seat corresponding to the target seatbelt; in a vehicle, there is generally a one-to-one relationship between seatbelts and seats.

[0031] Specifically, the seatbelt usage status of candidate seatbelts is obtained from the seatbelt buckle sensor of the current vehicle; the candidate seatbelts whose usage status is "in use" are identified as target seatbelts, and the target seat corresponding to the target seatbelt is determined.

[0032] Among them, the seat belt buckle sensor is used in the vehicle to monitor and provide real-time feedback on the seat belt buckle status.

[0033] For example, seat belt usage can be determined by seat belt buckle sensors in the current vehicle. The seat belt buckle sensors determine whether the buckle of a candidate seat belt is in a working state. If the buckle of a candidate seat belt is in a working state, it indicates that the seat belt is being used. If the buckle of a candidate seat belt is in an idle state, it indicates that the seat belt is not being used.

[0034] Understandably, prioritizing the seat belts currently being used by passengers and then proceeding with subsequent work on those seat belts can improve efficiency and reduce resource waste.

[0035] S120. Obtain the current tension of the target seat belt and the seat load of the target seat, and determine the pretensioning mode of the target seat belt based on the current tension and seat load.

[0036] The current tension force refers to the force exerted by the target seat belt on the passenger. Seat load refers to the weight of the passenger borne by the target seat. Pretension mode refers to the automatic tension force at which the target seat belt contracts in special circumstances such as a collision or sudden braking; specifically, pretension modes include no pretension mode, light pretension mode, and normal pretension mode. No pretension mode means the target seat belt does not require pretensioning. Light pretension mode means the target seat belt uses a first preset tension force during pretensioning. Normal pretension mode means the target seat belt uses a second preset tension force during pretensioning.

[0037] It should be noted that the first preset tension force is less than the second preset tension force. The first and second preset tension forces are artificially preset through a large number of experiments or empirical values.

[0038] Optionally, the passenger type in the target seat can be determined based on the current tension and seat load; and the pretensioning mode of the target seat belt can be determined based on the passenger type.

[0039] The passenger type refers to the type of user who is in the target seat and using the target seat belt, which can include healthy people such as adults and teenagers, as well as vulnerable people such as the elderly and young children.

[0040] For example, when the passenger type is a healthy person, the normal pretensioning mode can be determined as the pretensioning mode of the target seat belt; when the passenger type is a vulnerable person, the mild pretensioning mode can be determined as the pretensioning mode of the target seat belt.

[0041] Understandably, selecting different seatbelt pretensioning modes based on different passenger types can effectively prevent excessive seatbelt pretensioning force, which could cause discomfort to vulnerable individuals due to excessive restraint, thus helping to ensure passenger safety.

[0042] S130, Based on the pretensioning mode, the pretensioning operation of the target seat belt is controlled according to the electrical signal parameters obtained during the current vehicle driving process.

[0043] Among them, electrical signal parameters refer to various electrical signal information used to monitor and control the seat belt pretensioning operation. These electrical signal parameters are usually monitored by the vehicle's sensors. Electrical signal parameters may include AEB (Automatic Emergency Braking) signal, vehicle speed, brake pedal position, accelerator pedal position, lateral and longitudinal acceleration, steering wheel angle, steering wheel angular velocity, vehicle speed, yaw angle, etc.

[0044] Specifically, based on the electrical signal parameters obtained during the vehicle's operation, it is determined whether the vehicle is in a dangerous condition; if the vehicle is in a dangerous condition, the pretensioning operation of the target seat belt is controlled based on the pretensioning mode.

[0045] This application embodiment determines a target seatbelt from candidate seatbelts based on their usage status in the current vehicle, and identifies the corresponding target seat. It then acquires the current tension of the target seatbelt and the seat load of the target seat, and determines the pretensioning mode of the target seatbelt based on these parameters. Based on the pretensioning mode, it controls the pretensioning operation of the target seatbelt using electrical signal parameters acquired during vehicle operation. This technical solution improves the safety and reliability of active seatbelt pretensioning by selecting a suitable pretensioning mode for the target seatbelt based on its tension and seat load.

[0046] Example 2

[0047] Figure 2 This is a flowchart of a vehicle seatbelt control method according to Embodiment 2 of this application. Based on the technical solutions of the above embodiments, this embodiment refines "determining the pretensioning mode of the target seatbelt based on the current tension force and seat load" to "when the current tension force meets the current tension force pretensioning condition, the target seatbelt pretensioning mode is determined from a light pretensioning mode and a normal pretensioning mode based on the seat load; when the current tension force does not meet the current tension force pretensioning condition, the target seatbelt pretensioning mode is determined from a no-pretensioning mode and a normal pretensioning mode based on the seat load." It should be noted that for parts not detailed in this embodiment, please refer to the relevant descriptions in other embodiments. Figure 2 As shown, the method includes:

[0048] S210. Based on the current seat belt usage status of the candidate seat belts in the vehicle, determine the target seat belt from the candidate seat belts and determine the target seat corresponding to the target seat belt.

[0049] S220: Obtain the current tension of the target seat belt and the seat load of the target seat.

[0050] S230. When the current tension force meets the current tension force pretensioning conditions, determine the pretensioning mode of the target seat belt from the light pretensioning mode and the normal pretensioning mode according to the seat load.

[0051] The current tension preload condition is artificially set based on a large number of experiments or empirical values.

[0052] Optionally, if the seat load meets the first load pretensioning condition, the normal pretensioning mode is determined as the pretensioning mode of the target seat belt; if the seat load does not meet the first load pretensioning condition, the light pretensioning mode is determined as the pretensioning mode of the target seat belt.

[0053] The first load preload condition is set manually based on a large number of experiments or empirical values.

[0054] For example, if the current tension force is less than or equal to the tension force threshold, and the seat load is greater than or equal to the first load threshold, then the normal pretensioning mode is determined as the pretensioning mode of the target seat belt; if the seat load is less than the first load threshold, then the light pretensioning mode is determined as the pretensioning mode of the target seat belt.

[0055] S240. If the current tension force does not meet the current tension force pretensioning condition, determine the pretensioning mode of the target seat belt from the no pretensioning mode and the normal pretensioning mode according to the seat load.

[0056] The no-pretension mode refers to a mode in which the target seat belt does not need to be pretensioned, and is specifically used when the target seat is a child seat.

[0057] Optionally, if the seat load meets the second load pretensioning condition, the normal pretensioning mode is determined as the pretensioning mode of the target seat belt; if the seat load does not meet the second load pretensioning condition, the no pretensioning mode is determined as the pretensioning mode of the target seat belt.

[0058] The second load preload condition is artificially pre-set based on a large number of experiments or empirical values.

[0059] For example, if the seat load is greater than or equal to the second load threshold, the normal pretensioning mode is determined as the pretensioning mode of the target seat belt; if the seat load is less than the second load threshold, the target seat is determined to be a child seat, and the no-pretensioning mode is determined as the pretensioning mode of the target seat belt.

[0060] S250, based on pretensioning mode, controls the pretensioning operation of the target seat belt according to the electrical signal parameters obtained during the current vehicle driving process.

[0061] Optionally, when the pretensioning mode is normal pretensioning mode or light pretensioning mode, the rate of change of electrical signal parameters is determined based on the electrical signal parameters obtained during the current vehicle driving process; based on the pretensioning mode, the pretensioning operation of the target seat belt is controlled according to the rate of change of electrical signal parameters.

[0062] Among them, the rate of change of electrical signal parameters refers to the speed or magnitude of change of electrical signal parameters over time, and is used to evaluate the dynamic changes in vehicle status.

[0063] For example, if the rate of change of electrical signal parameters is greater than the rate of change threshold, the vehicle is determined to be in a dangerous condition. At this time, based on the pretensioning mode, the pretensioning operation of the target seat belt is controlled according to the rate of change of electrical signal parameters.

[0064] Furthermore, based on the pretensioning mode, the pretensioning operation of the target seat belt can be controlled according to the rate of change of electrical signal parameters. If the rate of change of electrical signal parameters meets the safe driving conditions, the pretensioning mode is adjusted to the no-pretensioning mode; if the rate of change of electrical signal parameters does not meet the safe driving conditions, the target tension force in the pretensioning mode is determined, and the current tension force of the target seat belt is adjusted to the target tension force.

[0065] Among them, safe driving conditions are artificially preset through a large number of experiments or empirical values; for example, it can be whether the rate of change of electrical signal parameters is less than or equal to a preset rate of change threshold.

[0066] For example, if the rate of change of the electrical signal parameters is less than or equal to a preset rate of change threshold, the pretensioning mode is adjusted to a no-pretensioning mode; if the rate of change of the electrical signal parameters is greater than the rate of change threshold, the target tension force in the pretensioning mode is determined, and the current tension force of the target seat belt is adjusted to the target tension force.

[0067] This application embodiment determines a target seatbelt and its corresponding target seat based on the seatbelt usage status of candidate seatbelts in the current vehicle. It acquires the current tension of the target seatbelt and the seat load of the target seat. If the current tension meets the pretensioning conditions, it determines the pretensioning mode of the target seatbelt from a light pretensioning mode and a normal pretensioning mode based on the seat load. If the current tension does not meet the pretensioning conditions, it determines the pretensioning mode of the target seatbelt from a no-pretensioning mode and a normal pretensioning mode based on the seat load. Based on the pretensioning mode, it controls the pretensioning operation of the target seatbelt according to electrical signal parameters acquired during vehicle operation. This technical solution, by systematically and specifically judging the seatbelt tension and seat load, can provide a precise pretensioning mode for the passenger in the target seat, selecting a suitable pretensioning method for the current passenger and improving passenger safety during driving.

It is applicable to situations where the passenger's seatbelt is actively pre-tensioned during vehicle operation.

[0072] The seat belt control module 330 is used to control the pretensioning operation of the target seat belt based on the electrical signal parameters obtained during the current vehicle driving mode.

[0073] This application embodiment determines a target seatbelt from candidate seatbelts based on their usage status in the current vehicle, and identifies the corresponding target seat. It then acquires the current tension of the target seatbelt and the seat load of the target seat, and determines the pretensioning mode of the target seatbelt based on these parameters. Based on the pretensioning mode, it controls the pretensioning operation of the target seatbelt using electrical signal parameters acquired during vehicle operation.
