A buckle device comprises a main body unit, a latch unit and a fastening unit. The main body unit includes a housing surrounding and defining an accommodating space, two first apertures provided in the housing, two slider blocks arranged in the accommodating space, and two first elastic bodies abutting against the slider blocks. The latch unit includes a tongue element and two tongue openings provided on the tongue element. The fastening unit includes two bolt bodies passing through the first apertures, and two second elastic bodies abutting against the bolt bodies. When the tongue element is separated from the two slider blocks, the two slider blocks are pushed by the two first elastic bodies, and the two bolt bodies is pushed against by the two slider blocks. When the tongue element is in contact with the two slider blocks, the two slider blocks are pushed by the tongue element, and the two bolt bodies are pushed into the two tongue openings by the two second elastic bodies, so that the tongue element can be securely fastened. Accordingly, the external pulling force of the tongue element can be increased, and the structure of the buckle device can be effectively improved.

A utility vehicle includes a frame assembly defined by a lower frame assembly and an upper frame assembly coupled to the lower frame assembly. The frame assembly supports a plurality of body panels. A roof, front windshield, rear windshield, and doors may be coupled to the frame assembly to enclose the operator area.

System and techniques for vehicle occupant monitoring are described herein. Sensor data, that includes visual image data, is obtained from a sensor array of the vehicle. An object carried by the vehicle is detected from the visual image data. A safety event for the vehicle may be identified based on the object detection and an operational element of the vehicle is altered in response to detecting the safety event.

An apparatus for controlling alcohol interlock includes a sensor that senses an environment of a driver's seat and a camera that obtains a face image of a passenger and an image of exhalation of the passenger. A controller activates a start lock mode of a vehicle and determines whether a condition for detecting components of the exhalation of the passenger is satisfied based on the environment of the driver's seat. The controller determines whether the exhalation of the passenger is exhalation of a driver based on the face image of the passenger and the image of the exhalation of the passenger, and determines whether to detect alcohol concentration in the exhalation of the passenger based on the determination result.

A system for detecting seatbelt routing includes: a state module configured to, based on a series of images over a period of time from a camera of a vehicle facing a seat, determine and output a routing state of a seatbelt of the seat; and a remediation module configured to, based on the routing state of the seatbelt of the seat, selectively perform at least one remedial action.

A system for detecting improper usage of a seatbelt of a vehicle includes a vehicle seat having a seat cushion and a seat back. A shoulder belt and a lap belt are intended to restrain an occupant sitting on the vehicle seat. The system includes a sensor module associated with the shoulder belt and the lap belt. The sensor module generates signals indicative of at least one parameter associated with the vehicle seat, the shoulder belt, and the lap belt when the occupant is sitting on the vehicle seat. The system also includes a controller that receives the signals indicative of the at least one parameter associated with the seat back, the shoulder belt, and the lap belt. The controller analyzes the received one or more signals, and determines whether the seatbelt is being used improperly by the occupant, based on the analysis.

In a method for operating a safety system of a motor vehicle, a corresponding safety system, and a motor vehicle equipped with such safety system, status signals from several sensor devices are captured by the safety system, wherein the status signals indicate respective status change of a functional unit of the motor vehicle. Thereafter, a chronological order of the status changes is determined and evaluated to detect a consistency or an inconsistency with the proper application of a seat belt of the motor vehicle. If an inconsistency is detected and it persists over a predetermined period of time, a control signal is transmitted by the safety system to a safety device of the motor vehicle.

A driver identification seatbelt system including a seatbelt system having at least one first belt with a first coupling member, and a second coupling member. The driver identification seatbelt system further including a fingerprint recognition member.

A method for controlling an autonomous driving operation comprising at least one processor includes determining a predicted driving condition of a vehicle; determining a predicted driving operation of the vehicle based on the predicted driving condition; determining necessity of wearing of a seat belt of a passenger, based on an image of the passenger captured by an interior vision sensor and the predicted driving operation; requesting the passenger to wear the seat belt and determining wearing of a seat belt of the passenger based on the necessity of wearing of a seat belt of the passenger; and controlling a driving operation of the vehicle based on a result obtained by determining the wearing of a seat belt of the passenger. The method of the present disclosure may be performed based on a deep neural network generated through machine learning and an Internet of Things (IoT) environment using a 5G network.

A restraint system for an occupant seat mounted in a motor vehicle includes a processor to produce at least one control signal to control either or both of an electronically controllable unit to disable or impede operation of the motor vehicle and a notification device to produce a notification unless, in sequence, a first sensor produces a first signal indicating detection of an occupant being seated in the occupant seat followed by at least one second sensor producing least one second signal indicating that a rotatable shaft of a web retractor coupled to a web of a restraint harness has rotated by at least a threshold amount followed by a third sensor producing a third signal indicating that a tongue of the restraint system is engaged with a buckle of the restraint system.
