[0019] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.
[0020] It should be noted that, unless otherwise specified, the embodiments of the present invention and the technical features thereof can be combined with each other.
[0021] Furthermore, the terms "first," "second," and "third," etc., included in the terminology of this invention are used to distinguish similar objects and are not necessarily used to describe a specific number or order. It should be understood that such terms can be used interchangeably where appropriate; this is merely a distinguishing method used in the embodiments of this invention when describing objects with the same attributes.
[0022] Furthermore, the vehicles involved in the embodiments of the present invention may be internal combustion engine vehicles that use an engine as a power source, hybrid vehicles that use an engine and an electric motor as power sources, electric vehicles that use an electric motor as a power source, etc.
[0023] Figure 1 This is a schematic diagram of the main steps of the first seatbelt torsion detection method according to an embodiment of the present invention from the vehicle end. Figure 1 As shown, the method for detecting seatbelt torsion mainly includes the following steps: Step S101: In response to the electronic control unit receiving an output signal from at least two copper wires of the seat belt; wherein the copper wires are integrated into the webbing of the seat belt and are connected to the electronic control unit.
[0024] In one embodiment, two or more copper wires can be integrated parallel to each other in the webbing of the seat belt, and each copper wire is connected to the electronic control unit (ECU). This allows the interaction between the magnetic fields of the copper wires to determine whether the seat belt is twisted. In a preferred embodiment, one copper wire is integrated on each side edge of the seat belt webbing; that is, the seat belt can integrate two copper wires, with each wire integrated on one side edge of the seat belt webbing. Figure 2 The copper wires are indicated by the thick lines on both sides of the webbing of the seat belt.
[0025] In another preferred embodiment, the webbing of the seat belt can be integrated with multiple copper wires in parallel, and the distance between each copper wire is the same, such as... Figure 3 The four copper wires shown in the thicker line of the seatbelt webbing.
[0026] Step S102: Identify that the output signal is an interaction between magnetic fields, generate warning information and output it.
[0027] In one embodiment, the present invention determines seatbelt twisting by the magnetic field interaction between copper wires, generates warning information, and outputs a reminder to the user to correct the seatbelt. In a further embodiment, step S102 can determine different warning levels for different twisting conditions, thereby generating corresponding warning information and warning measures. The specific implementation process includes: obtaining the number of nodes in the seatbelt with interacting magnetic fields, determining the corresponding warning level, and generating corresponding warning information and warning measures.
[0028] In a further embodiment of the present invention, step S102 can determine the warning level based on the number of nodes indicating seatbelt twisting, thereby generating corresponding warning information and warning measures. The specific implementation process includes: in response to the number of nodes being less than or equal to a preset first quantity threshold, determining the warning level as Level 1, generating warning information, and broadcasting it via voice. For example: the first quantity threshold is 1, the number of nodes is 1, the warning level is determined to be Level 1, a "seatbelt twisting" warning message is generated, displayed, and accompanied by a voice broadcast of the warning information.
[0029] In a further embodiment of the present invention, step S102 can configure a preset first quantity threshold and a second quantity threshold, wherein the first quantity threshold is less than the second quantity threshold; in response to the number of nodes being greater than the preset first quantity threshold and less than the preset second quantity threshold, the warning level is determined to be level two, a warning message is generated and output, and a first frequency of tightening / loosening operation is performed on the seat belt. Preferably, the frequency configuration of the first frequency of tightening / loosening operation can be within a preset first range (for example, the preset first range can be configured to be 1 time / 3 seconds to 1 time / 6 seconds), that is, the present invention can locate the first frequency of the current tightening / loosening operation within the preset first range according to needs. For example: the first quantity threshold is 1, the second quantity threshold is 3, the number of nodes is 2, the warning level is determined to be level two, a warning message of "severely twisted seat belt" is generated and output for display, and a first frequency of tightening / loosening operation is performed on the seat belt, for example, the current first frequency of tightening / loosening operation is 1 time / 4 seconds, to realize the warning prompt to the personnel. It is worth noting that after the seat belt is tightened or loosened at the first frequency during the preset time period, in response to the detection that the seat belt warning level remains unchanged, the seat belt is tightened or loosened at the second frequency, thereby providing enhanced warning to the personnel.
[0030] In a further embodiment of the present invention, step S102, in response to the number of nodes being greater than or equal to a preset second quantity threshold, determines the warning level as level three, generates and outputs a warning message, and performs a second frequency of tightening / loosening operation on the seat belt. Preferably, the frequency of the second frequency of tightening / loosening operation is configured within a preset second interval, the frequency corresponding to the second interval being greater than the frequency corresponding to the first interval (for example, the preset second interval can be configured from 1 time / 0.5 seconds to 1 time / 1 second), that is, the present invention can locate the second frequency of the current tightening / loosening operation within the preset second interval as needed. For example: the second quantity threshold is 3, the number of nodes is 3, the warning level is determined to be level three, a warning message "The seat belt is severely twisted, please correct it immediately" is generated and output with a flashing display, and a second frequency of tightening / loosening operation is performed on the seat belt, the current second frequency of tightening / loosening operation being 1 time / 0.5 seconds. It is worth noting that after performing the second frequency of tightening / loosening operation on the seat belt within a preset time period, in response to detecting that the seat belt warning level remains unchanged, an operation to continuously tighten the seat belt is performed.
[0031] As an example requiring explanation, step S102 can also execute a warning for seat belt twisting based on different vehicle driving scenarios. The specific implementation process includes: detecting that the vehicle driving scenario meets preset scenario conditions, generating and outputting warning information. Examples of scenario conditions include, but are not limited to: severe inclement weather conditions, bumpy road environments, accident-prone road environments, etc. It can be seen that when the present invention detects a seat belt twisting problem, it can determine whether to generate warning information based on the current vehicle driving scenario. That is, when the vehicle driving scenario meets preset scenario conditions such as severe inclement weather conditions, bumpy road environments, accident-prone road environments, etc., a warning message is generated and output; when the vehicle driving scenario does not meet the preset scenario conditions such as severe inclement weather conditions, bumpy road environments, accident-prone road environments, etc., no warning message is generated.
[0032] In some other embodiments, step S102 can flexibly determine whether to issue a warning based on the location of the seatbelt twist. The specific implementation process includes: locating the position information of the interacting magnetic field on the seatbelt, determining that the position information belongs to a preset seatbelt warning area, generating and outputting warning information. For example, the two ends of the preset seatbelt warning area are each 5cm away from the two endpoints of the seatbelt. It can be seen that this invention can determine whether seatbelt twisting can affect user comfort and safety by configuring the seatbelt warning area. For seatbelt twisting that affects user comfort and safety, warning information is generated and output; for seatbelt twisting that does not affect user comfort and safety, no warning information is generated.

For example, memory can be a hard disk drive or other storage media located in a housing different from that of a computer. Therefore, references to processors or computers will be understood to include references to a collection of processors or computers or memories that may or may not operate in parallel. Unlike using a single processor to perform the steps described herein, some components, such as steering and deceleration components, may each have their own processor that performs calculations only related to the component's specific function.
