[0028] Proper shoulder belt positioning contributes to occupant comfort and seat belt effectiveness. A shoulder belt positioned too high or too low on the shoulder can be uncomfortable. Furthermore, an uncomfortable shoulder belt may be positioned in a way that reduces its effectiveness. Additionally, a shoulder belt positioned too high or too low on the shoulder may not be as effective as one that is positioned correctly. Many occupants do not understand how a shoulder belt should be positioned correctly to maximize comfort and effectiveness.

[0029] The present disclosure relates to a system that detects improper routing of the shoulder belt and provides feedback to the occupant on how the seat belt can be routed correctly.

[0030] A vehicle according to the present disclosure is in Fig. 1, generally designated by 10. The vehicle 10 comprises a body 12, which is supported by several wheels 16. The body 12 partially defines a passenger compartment 20, which contains occupant seats, one of which is designated by 24. Each occupant seat 24 includes an associated seat belt 26, which restrains an occupant in the event of a sudden change in the acceleration forces acting on the vehicle 10.

[0031] With reference to the Fig. 2, Fig. 3 and Fig. 4 and with continued reference to the Fig. 1 The seat belt 26 contains a lap belt 28 and a shoulder belt 30. The seat belt 26 contains a retractor mechanism 32 which is connected to a B-pillar 36 ( Fig. 1) is coupled in vehicle 10. The B-pillar 36 also carries a shoulder belt anchorage 38. The shoulder belt anchorage 38 can be manually moved along the B-pillar 36 to change the height of the shoulder belt anchorage to accommodate occupants of different sizes. A lap belt anchorage 40 is coupled to a floor (not shown) in the passenger compartment 20. The occupant seat 24 includes a seat base 42 and a backrest 44, which support the occupant.

[0032] In Fig. According to the present disclosure, the vehicle 10 includes an interior sensor system 46 that detects whether an occupant is present in the passenger seat 24 and whether the shoulder belt 30 is properly guided. For example, the interior sensor system 46 can detect whether the shoulder belt 30, as shown in Fig. 3 is shown, whether the shoulder strap is positioned too low on an occupant, or whether the shoulder strap 30, as shown in Fig. As shown in Figure 4, the seat belt 30 is positioned too high on the occupant. In both cases, the occupant is provided with instructions on how to properly position the shoulder belt 30, as explained in detail here. The interior sensor system 46 also detects the position of the seat belt 26 on the occupant. The interior sensor system 46 includes a camera 48 and a mass sensor 50. The camera 48 is directed towards the occupant seat 24, while the mass sensor 50 is integrated into the seat base 42 and the backrest 44.

[0033] In a non-restrictive example, the mass sensor 50 can include a first pressure sensor 52 connected to a first bladder 54 mounted in the seat base 42, and a second pressure sensor 56 connected to a second bladder 58 mounted in the backrest 44. The first pressure sensor 52 and the second pressure sensor 56 output signals representing pressure changes in the first bladder 54 and the second bladder 58, respectively, proportional to the mass of an occupant on the occupant seat 24. The interior sensor system 46 can also include a position sensor 59 that detects the position of the shoulder belt anchorage 38 on the B-pillar 36.

[0034] According to the present disclosure, the vehicle 10 includes a controller 60 for detecting the guidance of the seat belt. The controller 60 is operationally connected to the interior sensor system 46. As in Fig. As shown in Figure 5, the controller 60 contains a central processing unit (CPU) 64, non-volatile memory 66, an occupant classification module 70, a seatbelt guidance module 72, a guidance quality module 74, a notification module 78, and a reconnaissance module 80. The occupant classification module 70 classifies the occupant in the occupant seat 24 based on the mass detected by the mass sensor 50 and the images captured by the camera 48.

[0035] The classification can include a population-based percentile. For example, the occupant classification module 70 evaluates physical characteristics or reference points of the occupant. The reference points can include a mass based on inputs from the mass sensor 50, the position of the neck base, and a shoulder position, along with other physical characteristics that include the occupant's size based on their position on the occupant seat 24, derived from images captured by the camera 48, to develop an occupant classification. The physical characteristics can also include the length of the neck and the width of the shoulder, both of which can be determined from images captured by the camera 48. For example, the images are processed and evaluated by the occupant classification module 70 to, for example,to determine the position of the occupant's shoulder in relation to the occupant seat 24, the length of the neck, the shoulder width and the like.

[0036] An occupant can be classified as 95% male if they are taller than 95% of the males in the population, 50% male if they are taller than 50% of the males in the population, and 5% male if they are within 5% of the population. The occupant classification can also include percentages of the female population and percentages of the child population. The occupant classification is then used by Occupant Classification Module 70 to determine an expected shoulder belt guidance and shoulder belt anchorage position associated with the classification. Controller 60 then determines output values ​​for Shoulder Belt Position Limits 30 based on the reference points determined by Occupant Classification Module 70.The initial values ​​of the position limits determine the expected height of the shoulder strap anchorage.

[0037] The expected shoulder belt anchorage height defines a height of the shoulder belt anchorage 38 that would likely result in proper shoulder belt routing for an occupant with the specified occupant classification. For example, for a 95% male individual, the shoulder belt anchorage 38 would be expected to be at a height "x", whereas for a 50% male individual, the shoulder belt anchorage would be expected to be at a height "y" lower than "x" for the shoulder belt 30 to be properly routed. Proper shoulder belt routing is defined as a condition in which the shoulder belt 30, as described in Fig. 2 is shown, lying centrally on the occupant's shoulder.

[0038] The guidance module 72 evaluates the images captured by camera 48 to determine the actual location of the shoulder strap on the occupant. For example, the guidance module 72 first processes the images captured by camera 48 to evaluate whether the shoulder strap 30 is visible. If the shoulder strap is not visible, for example, hidden behind the occupant, or if the shoulder strap 30 is not routed over the occupant's shoulder, a negative guidance signal is issued to the notification module 78, which provides a warning to the occupant. If the shoulder strap 30 is visible, the guidance module 72 transmits images of the shoulder strap to the guidance quality module 74, which compares the actual position of the shoulder strap with the expected position of the shoulder strap anchorage.

[0039] Module 74, the guidance quality module, determines the guidance quality by comparing the actual position data of the shoulder belt, such as the shoulder belt angle, distance to the occupant's neck, and the shoulder belt's position on the occupant's shoulder, from Module 72 (seat belt guidance detection) and the shoulder belt anchorage position data from Position Sensor 56, with the expected shoulder belt guidance and shoulder belt anchorage position from Module 70 (occupant classification). Module 74 evaluates whether the shoulder belt is in the correct position for the respective occupant size. If the shoulder belt 30 is correctly positioned, for example, if it extends over the occupant within the calculated position limits, Module 74 outputs a positive guidance signal.However, if the shoulder strap 30 is located outside the calculated position limits, e.g., if it is too close to the occupant's neck (. Fig. 3) is located or falls off the shoulder ( Fig. 4), Module 72, which deals with leadership quality, outputs a negative leadership signal.

[0040] If the guidance quality module 72 issues a positive guidance signal, the notification module 78 simply provides the occupant with a notification that the shoulder strap 30 is properly guided. Conversely, if the guidance quality module 72 issues a negative guidance signal, the notification module 78 provides the occupant with a notification that the shoulder strap 30 could benefit from an adjustment, and the reconnaissance module provides the occupant with an instruction describing how to adjust the shoulder strap 30 for proper guidance. For example, if the shoulder strap 30 is too close to the occupant's neck, the occupant is instructed to lower the shoulder strap anchor 38. If the shoulder strap 30 is too low on the occupant's shoulder, the occupant is instructed to raise the shoulder strap anchor 38.

[0041] The instruction may be in the form of voice prompts provided via vehicle speakers 90, text displayed on a section of a display device (not specifically designated) of an infotainment system 96, or instructional videos displayed on the infotainment system 96. The controller 60 further includes an adjustment module 84 which, if provided, controls a linear actuator 98 coupled to the shoulder belt anchorage 38 to adjust the position of the shoulder belt.

[0042] In Fig.Section 6 describes a method 160 for identifying improper shoulder belt routing and providing feedback to an occupant regarding adjustments that will lead to proper routing. In Block 162, details of an occupant are captured by the interior sensor system 46. The camera 48 captures images of the occupant, while the mass sensor 50 determines the occupant's mass. The position sensor 56 detects the current position of the shoulder belt anchor point 38. In Block 164, the occupant is classified based on the captured mass and the images captured by the camera 48. The occupant classification module 70 evaluates signals from the first pressure sensor 52 and the second pressure sensor 56 to determine the occupant's weight. The occupant classification module 70 also processes the images captured by the camera 48 to determine the occupant's relative position, e.g.,to determine the position of the backrest 44. The occupant classification module 70 further establishes expected output values ​​for the shoulder strap position based on the occupant classification. The images from camera 48, processed by the occupant classification module 70, are passed to the guidance detection module 72 to determine how the shoulder strap 30 is guided.

[0043] In block 166, the guidance quality module 72 evaluates the inputs from the occupant classification module 70 and the guidance detection module 72 to determine how the shoulder belt anchorage 38 actually acts on the occupant. For example, the guidance quality module 72 evaluates the expected output values ​​set by the occupant classification module 70 to determine a proper shoulder belt anchorage position for the occupant. In block 168, the controller 60 evaluates whether the current or actual position of the shoulder belt anchorage is aligned with the proper shoulder belt anchorage position set as the output value by the occupant classification module 70. If block 168 determines that the shoulder belt 30 is properly guided, the controller 60 provides the occupant with a proper guidance notification in block 180.

[0044] If, on the other hand, block 168 determines that the shoulder belt 30 is improperly routed, a notification of the improper routing is displayed to the occupant in block 190. In addition to the notification of improper routing, the controller 60 provides the occupant with adjustment suggestions in the form of voice, text, and / or video suggestions relating to how the shoulder belt 30 can be adjusted for proper routing, e.g., by moving the shoulder belt anchor point 38 along the B-pillar 36. If the vehicle is equipped accordingly, the controller 60 in block 192, via the adjustment module 84, can automatically adjust the position of the shoulder belt anchor point 38 on the B-pillar 36, if authorized by the occupant, to achieve proper shoulder belt positioning.

[0045] It is important to understand that the examples set forth in this disclosure describe a system that not only detects improper shoulder belt routing but also provides suggestions for the specific occupant regarding how the shoulder belt can be properly routed. These suggestions may take one or more forms, including verbal instructions, text-based instructions, and / or instructional videos, which may be displayed on an integrated infotainment system. Furthermore, if equipped in this way, the system may move the shoulder belt anchorage to a selected position to achieve proper shoulder belt routing tailored to a specific occupant.Furthermore, the instructions may be based solely on the mass of the occupant or on images captured by the camera and need not include the specific steps described here.
