An occupant protection device for a vehicle includes a collision detector, a main airbag, a belt airbag, a belt controller, a distance detector, and an airbag controller. The collision detector detects a collision of the vehicle. In response to the collision detector detecting the collision, the main airbag deploys from a storage position toward an occupant seated on a seat of the vehicle. The belt airbag is stored in a seatbelt. The belt controller controls winding of the seatbelt, extraction of the seatbelt, and prohibition of the extraction of the seatbelt. The distance detector detects a distance from the storage position to the occupant. When the collision detector detects the collision of the vehicle and the detected distance is equal to or greater than a predetermined distance, the airbag controller deploys the belt airbag from within the seatbelt without causing the belt controller to prohibit the extraction of the seatbelt.

An occupant monitoring device for a vehicle is configured to monitor an occupant sitting on a seat provided in the vehicle and includes a light projector, an imaging device, and a processor. The light projector is configured to project light toward the occupant sitting on the seat. The imaging device is configured to capture an image of the occupant sitting on the seat. The processor is configured to control the light projector and the imaging device to capture the image of the occupant sitting on the seat. In a case where a collision of the vehicle is neither predicted nor detected, the processor causes the imaging device to capture an image of behavior of the occupant corresponding to either one of travel control and behavior of the vehicle so as to change occupant protection control.

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.

A force-limiting device, especially for a seat belt system (10) in a vehicle, has a force transducer (20) interacting with webbing (14) for which a normal webbing path is provided. The force transducer (20) includes a webbing track (30) that in a non-force-limiting position extends in parallel to the normal webbing path and in a force-limiting position extends inclined relative to the normal webbing path so that the force transducer (20) in the force-limiting position sets a predetermined extension force (F) required to move the webbing (14) vis-à-vis the force transducer (20) in a direction of belt extension (R).

A restraint system for a vehicle, with which in a pre-crash phase prior to a predicted front crash time a vehicle occupant resting on a vehicle seat can be raised from a comfort position to an upright operative position by a forward displacer, in which in a crash phase a seat belt fastened on the vehicle occupant exerts a restraining effect on the vehicle occupant, in which an electromotive reversible belt pretensioner is activated to limit the restraining force exerted on the vehicle occupant to a predefined force level, namely by means of forward displacement of the vehicle occupant along a belt force limiting travel. In accordance with the invention, when raising the vehicle occupant to the operative position in the pre-crash phase, the electromotively reversible belt pretensioner generates a pre-crash belt slack so as to provide the pre-crash belt pullout travel required for raising the vehicle occupant in a restraining-force-free manner.

A vehicle occupant notification apparatus provides a notification to a vehicle occupant by retracting a seatbelt of a vehicle and includes an operation-amount measuring instrument, an arithmetic controller, and a retraction device. The operation-amount measuring instrument measures a measurement seatbelt operation amount when the vehicle occupant sits on a seat of the vehicle and fastens the seatbelt. The measurement seatbelt operation amount is either one of a measurement seatbelt pull-out amount and a measurement seatbelt pull-out angle. The arithmetic controller determines whether the measurement seatbelt operation amount is larger than or equal to a predetermined value. The retraction device varies a retraction amount in the retraction of the seatbelt when the notification is to be provided by retracting the seatbelt based on a command from the arithmetic controller. The command indicates that the measurement seatbelt operation amount is larger than or equal to the predetermined value.

Methods, systems, and apparatus for automatically responding to at least partial submersion of a vehicle in water. The system includes a sensor configured to detect sensor data indicating whether the vehicle is at least partially submerged in water. The system includes an electronic control unit (ECU) connected to the sensor. The ECU is configured to determine that the vehicle is at least partially submerged in water based on the sensor data. The ECU is also configured to adjust at least one feature of the vehicle in response to the determination that the vehicle is at least partially submerged in water.

A smart belt system to be worn by a person is described here. The smart belt system includes an elongated belt, a microprocessor coupled to the belt, a bus disposed within the elongated belt configured to conduct data to the microprocessor, a rechargeable power supply coupled to the belt and configured for providing electrical power to the microprocessor, and a mobile communication device in wireless communication with the microprocessor and having an application executing and stored in the mobile communication device.

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.

An occupant classification system comprises a capacitive sensor configured to measure capacitance. The capacitive sensor is at least partially arranged between a seat frame and at least one of a seat cover and a seat cushion of a seat. A sensor is configured to measure at least one of weight and pressure on the seat. The sensor is at least partially arranged between a vehicle structure and a component of the seat. A controller is configured to generate an occupant classification based on the measured capacitance and the at least one of the measured weight and the measured pressure on the seat.
