A vehicle includes a body holding device configured to hold the body of a seated driver; a travel control unit configured to drive the vehicle body so that it travels; and a maximum vehicle speed setting unit configured to set a set maximum vehicle speed. The travel control unit controls an output from the driving unit based on the operation amount of an accelerator device if the vehicle speed is lower than the set maximum vehicle speed, and restricts the output from the driving unit irrespective of the operation amount of the accelerator device if the vehicle speed is equal to or higher than the set maximum vehicle speed. The maximum vehicle speed setting unit sets, if it is detected that the body holding device is worn, a first vehicle speed as the set maximum vehicle speed, and sets, if it is detected that the body holding device is not worn, a second vehicle speed lower than the first vehicle speed as the set maximum vehicle speed.

A computer implemented method for detecting whether a seat belt is used in a vehicle comprises the following steps carried out by computer hardware components: acquiring an image of an interior of the vehicle; determining a plurality of sub-images based on the image; detecting, for at least one of the sub-images, whether a portion of the seat belt is present in the respective sub-image; and determining whether the seat belt is used based on the detecting.

In one embodiment, a system of detecting seat belt operation in a vehicle includes at least one light source configured to emit a predetermined wavelength of light onto structures within the vehicle, wherein at least one of the structures is a passenger seat belt assembly having a pattern that reflects the predetermined wavelength at a preferred luminance. At least one 3-D time of flight camera is positioned in the vehicle to receive reflected light from the structures in the vehicle and provide images of the structures that distinguish the preferred luminance of the pattern from other structures in the vehicle. A computer processor connected to computer memory and the camera includes computer readable instructions causing the processor to reconstruct 3-D information in regard to respective images of the structures and calculate a depth measurement of the distance of the reflective pattern on the passenger seat belt assembly from the camera.

Various implementations include a system for adjusting the position of a seatbelt in a vehicle. The system includes a shoulder anchor, at least one sensor, and a processor. The shoulder anchor is for receiving a seatbelt. The shoulder anchor is movable relative to a seat disposed within the vehicle. The processor is in electrical communication with the sensor and a memory. The processor executes computer-readable instructions stored on the memory. The instructions cause the processor to receive sensor data from the sensor, determine whether the seatbelt is within an expected area on a person in the seat based on the received sensor data, and cause the shoulder anchor to move relative to the seat in response to the seatbelt being outside of the expected area on the person in the seat such that the seatbelt is moved into the expected area.

A vehicle includes a safety device, a camera sensor configured to detect an obstacle around the vehicle, a radar sensor configured to detect the obstacle around the vehicle, and a controller configured to predict a collision state and a collision position of the vehicle through the camera sensor and the radar sensor, determine whether to control the safety device based on at least one of a vehicle type, a collision speed, a seat position of an occupant, whether the occupant wears a seat belt, a gender of the occupant, whether the occupant is an infant, or a size of the occupant, in response to a prediction result, and control the safety device depending on device determination result.

An occupancy detection system consists of a master controller for a series of joined receivers consisting of reader modules and transponder modules in close proximity to one another. The reader modules are able to both send power to the transponder modules wirelessly and receive signals from the transponder modules, where the transponder modules are sending signals based on information received from buckle sensors, occupancy sensors, or both. The transponder modules, set in each seat of the vehicle, will get the latch/unlatch signals from the buckles, and send this information back through the reader modules to the main controller. The main controller will interface with the vehicle to provide user interface notifications.

A system and method for calibrating a vision system includes a selective wavelength interactive material located within the cabin of the vehicle and a control system in communication with the camera. The material is arranged as a pattern having pattern elements configured to reflect or absorb infrared light from an infrared light source. The control system is configured compare a captured image from the vision system that shows the pattern elements and calibrate the vision system based on a comparison of the captured image. Additionally or alternatively, the selective wavelength interactive material is disposed on a surface of a safety belt and the control system is configured to determine that an occupant seated in a seat is wearing a safety belt associated with the seat when the captured images show that the selective wavelength interactive material on the surface of the safety belt extending across the occupant seated.

A method of controlling an airbag inflator, may include determining, when an occupant is accommodated on a seat, whether the weight of the occupant is in which of first to fourth weight ranges sequentially allocated by a controller, performing a first logic for operating an inflator at the lowest one of three intensities by the controller when it is determined that the weight of the occupant is in the lightest first weight range, and performing a second logic for operating the inflator at the intermediate intensity or a third logic for operating the inflator at the highest intensity by the controller, according to conditions such as a position of a seat, a state of operation of a recliner, a collision condition, a collision pulse, and wearing of a belt, when it is determined that the weight of the occupant is in the third or fourth weight range.
