Abstract: Disclosed is a method of detecting a seat belt of a vehicle, the method comprising: storing, by a controller, a pattern before an occupant of a vehicle wears a seat belt webbing and a pattern after the occupant of the vehicle wears the seat belt webbing photographed through a region of interest of a vision sensor in a memory; receiving, by the controller, an image for the seat belt webbing photographed in the region of interest of the vision sensor; determining, by the controller, whether the pattern of the seat belt webbing stored in the memory is detected from the image of the seat belt webbing; and when the pattern of the seat belt webbing is not detected, controlling, by the controller, a display device to display a first warning message indicating that the seat belt webbing is not detected.

Abstract: An automation method of an artificial intelligence (AI)-based diagnostic technology for equipment application includes receiving one or more pieces of data among vibration data, noise data, and controller area network (CAN) data, a data input processing operation of trimming the input data, an operation of extracting features from the trimmed data, setting a setting value of a hyper-parameter with respect to the one or more pieces of data thereamong, and generating a total of N models to include both of machine learning (ML) and deep learning (DL) as N individual models and generating ensemble prediction model structures for the N individual models. As a parameter updating is being proceeded due to the hyper-parameter so as to minimize values of cost functions of the N individual models, a reward for model accuracy performance is optimized and the ensemble prediction model structures of the N individual models change.

Abstract: A seat belt apparatus of a vehicle described in the present disclosure includes a seat belt coupled to a seat and including a webbing comprising a detectable material; a vision sensor configured to generate an image by capturing a field of view region including the seat; and a monitoring system configured to detect a length of the webbing e.g., based on the pattern coated with the at least one paint in the image, and determine whether a user wears the seat belt as desired or erroneously wears the seat belt based on the detected length of the webbing.

Abstract: A seatbelt airbag for a vehicle is provided. The airbag is inflated in a seatbelt to restrain an occupant to reduce an injury to the occupant caused by the seatbelt. Particularly, since the airbag is locally inflated at occupant's shoulder and hip which are susceptible to injury by the seatbelt, an inflation speed is controlled, an impact is minimized, and the occupant may be restrained in the seat more rapidly and stably.

Abstract: An air belt apparatus for a vehicle may include an air belt coupled to an inflator formed at a predetermined position in a seat back, the air belt being configured to be placed on a shoulder portion of a driver, and a seat belt including a webbing passing through the air belt, the webbing being extracted from a retractor spaced from the inflator with a predetermined distance.
