Abstract

In accordance with various embodiments, methods, systems, and vehicles are provided. In various embodiments, the vehicle includes a body; one or more occupant seats disposed within the body for an occupant of the vehicle; and, for each occupant seat, a restraint device, one or more sensible elements, and one or more sensors. The restraint device is configured to provide restraint for the occupant when the restraint device is properly worn by the occupant. The one or more sensors are disposed within the occupant seat. The one or more sensible elements are disposed as part of the restraint device. The one or more sensors are disposed within the occupant seat, and are configured to sense the one or more sensible elements when the one or more sensible elements are in proximity to the one or more sensors, as an indication that the restraint device is not properly worn by the occupant.

Claims

1. A system comprising:

one or more sensible elements disposed as part of a restraint device of an occupant seat of a vehicle, the restraint device configured to provide restraint for an occupant of the occupant seat when the restraint device is properly worn by the occupant; and

one or more sensors disposed within the occupant seat, wherein the one or more sensors are configured to sense the one or more sensible elements when the one or more sensible elements are in proximity to the one or more sensors, as an indication that the restraint device is not properly worn by the occupant, and wherein the one or more sensors disposed in the occupant seat are further configured to detect a stowed latch plate of the restraint device when the restraint device is not worn and is in a stowed state.

2. The system of claim 1, wherein the one or more sensors are disposed in one or more of the following regions of the occupant seat:

a seat back, a seat bottom, and a joint between the seat back and the seat bottom.

3. The system of claim 2, wherein the one or more sensors comprise a plurality of sensors disposed in one or more of the following regions of the occupant seat:

the seat back, the seat bottom, and the joint between the seat back and the seat bottom.

4. The system of claim 1, wherein:

the one or more sensible elements are disposed in a shoulder belt of the restraint device; and

the one or more sensible elements are configured to detect routing of the shoulder belt.

5. The system of claim 1, wherein:

the one or more sensible elements are disposed in a lap belt of the restraint device; and

the one or more sensible elements are configured to detect routing of the lap belt.

6. The system of claim 1, wherein the one or more sensible elements are one of a) placed in proximity to, b) embedded into, and c) attached to a webbing of the restraint device.

7. The system of claim 6, wherein the one or more sensible elements comprise one of a metallic sensible element, a magnetic sensible element, and an RFID tag.

8. The system of claim 6, wherein the one or more sensible elements include a sensing element pattern in proximity to the webbing that is detected by the one or more sensors.

9. The system of claim 8, further comprising:

the occupant seat.

10. The system of claim 1 wherein:

the one or more sensors disposed within the occupant seat do not sense below a detection threshold the one or more sensible elements in the restraint device when the restraint device is properly worn by the occupant; and

the one or more sensors disposed within the occupant seat do sense above a detection threshold the one or more sensible elements in a restraint device when the restraint device is improperly worn by the occupant.

11. The system of claim 1, wherein the response strength from the sensor varies with the distance of the sensible element to the sensor with a stronger response for a closer distance than for a longer distance.

12. The system of claim 1, further comprising:

a processor configured to take an action when the restraint device is not properly worn by the occupant.

13. The system of claim 12, wherein the processor is configured to take the action if, and only if, the restraint device is determined to not be properly worn by the occupant based on the detection of at least two of the sensible elements of the restraint device by the sensors.

14. The system of claim 1, further comprising:

the restraint device.

15. A vehicle comprising:

a body;

one or more occupant seats disposed within the body for an occupant of the vehicle; and

for each occupant seat;

a restraint device configured to provide restraint for the occupant when the restraint device is properly worn by the occupant;

one or more sensors disposed within the occupant seat; and

one or more sensible elements disposed as part of the restraint device;

wherein the one or more sensors are configured to sense the one or more sensible elements when the one or more sensible elements are in proximity to the one or more sensors, as an indication that the restraint device is not properly worn by the occupant, and wherein the one or more sensors disposed within the occupant seat are further configured to detect a stowed latch plate of the restraint device when the restraint device is not worn and is in a stowed state.

16. The vehicle of claim 15, further comprising:

a processor that is configured to take an action when the restraint device is not properly worn by the occupant.

17. The vehicle of claim 15, wherein the processor is configured to take the action if, and only if, the restraint device is determined to not be properly worn by the occupant based on the detection of at least two of the sensible elements of the restraint device by the sensors.

18. A method comprising:

detecting, via one or more sensors disposed within an occupant seat of a vehicle, one or more sensible elements that are disposed as part of a restraint device of the vehicle, wherein the restraint device is configured to provide restraint for an occupant of the occupant seat when the restraint device is properly worn by the occupant, and wherein the detecting is based in part on whether the one or more sensors disposed in the occupant seat detect a stowed latch plate of the restraint device when the restraint device is not worn and is in a stowed state; and

taking an action, via a processor, when the restraint device is not properly worn by the occupant.

19. The method of claim 18, wherein:

the vehicle comprises an autonomous vehicle; and

the step of taking the action comprises not allowing movement of the autonomous vehicle when the restraint device is not properly worn by the occupant.

20. The method of claim 18, wherein the step of taking the action, via the processor, is performed if, and only if, the restraint device is determined to not be properly worn by the occupant based on the detection of at least two of the sensible elements of the restraint device by the sensors.
