Abstract
A system includes an in-cabin sensor, a seatbelt routing zone module, and a seatbelt routing classification module. The in-cabin sensor is operable to generate an image of an occupant in a vehicle seat. The seatbelt routing zone module is configured to generate a seatbelt routing zone based on at least one of a size of the occupant in the image and a shape of the occupant. The seatbelt routing classification module is configured to determine whether a seatbelt is routed properly around the occupant based on whether the seatbelt is at least partially within the seatbelt routing zone.
Claims20
A system comprising:
- an in-cabin sensor operable to generate an image of an occupant in a vehicle seat;
- a seatbelt routing zone module configured to generate a seatbelt routing zone based on at least one of a size of the occupant in the image and a shape of the occupant;
- a seatbelt routing classification module configured to determine whether a seatbelt is routed properly around the occupant based on whether the seatbelt is at least partially within the seatbelt routing zone;
- and
- a landmark module configured to generate a landmark representing a geometry of the occupant in the image and a posture of the occupant in the image, wherein the seatbelt routing zone module configured to generate the seatbelt routing zone based on the landmark,
- wherein the landmark includes at least one of a stick figure representation of the occupant and a shell representation of the occupant.
A system comprising:
- an in-cabin sensor operable to generate an image of an occupant in a vehicle seat;
- a landmark module configured to generate a landmark based on the image, wherein the landmark includes at least one of a stick figure representation of the occupant and a shell representation of the occupant;
- a seatbelt routing zone module configured to:
- generate a seatbelt routing zone based on the landmark;
- determine a size of the seatbelt routing zone, a shape of the seatbelt routing zone, a location of the seatbelt routing zone based on at least one of a size of the occupant and a shape of the occupant as indicated by the landmark;
- and
- adjust the location of the seatbelt routing zone and the shape of the seatbelt routing zone based on a posture of the occupant as indicated by the landmark;
- and
- a seatbelt routing classification module configured to determine whether a seatbelt is routed properly around the occupant based on whether the seatbelt is at least partially within the seatbelt routing zone.

- and
- a seatbelt routing classification module configured to determine whether a seatbelt is routed properly around the occupant based on whether the seatbelt is at least partially within the seatbelt routing zone,
- wherein the seatbelt routing zone module is configured to generate the seatbelt routing zone based on whether a child restraint seat is present in the vehicle seat.
