A device for restraining a passenger in a relaxed position for a vehicle seat and a method for controlling the device are configured such that when a seated passenger in an autonomous vehicle enters a relaxed mode, and thus is seated in a relaxed posture in the vehicle seat, and when a vehicle speed is greater than or equal to a predetermined speed, the device automatically operates such that legs of the seated passenger can be restrained, thereby effectively protecting the passenger in the relaxed position if an accident occurs. The device includes a rod member coupled to a seat cushion and configured to have a variable length; and a support foam connected to one end of the rod member and positioned in front of the seated passenger to restrain the legs of the seated passenger.

A vehicle includes a floor and a seat supported by the floor. The seat is translatable relative to the floor along a longitudinal axis of the vehicle. An airbag housing is supported by the floor and is disposed alongside the seat. The airbag housing is translatable relative to the floor along the longitudinal axis. An airbag is supported by the airbag housing. The airbag is inflatable to an inflated position that extends from the airbag housing away from the floor.

System, methods, and other embodiments described herein relate to sensing ingress of water in a vehicle. In one embodiment, a method includes acquiring, from a radar of a vehicle, radar data about a passenger cabin of the vehicle. The method includes determining a current state of the passenger cabin according to the radar data. The method includes, responsive to identifying that the current state indicates an ingress of water into the passenger cabin, generating a response to the ingress of the water.

A system for controlling operation of a vehicle includes a millimeter-wave radar sensor, a processor, and a memory communicably coupled to the processor. The memory stores a sensor control module configured to automatically control operation of the radar sensor to perform at least one radar scan of at least a portion of an interior of the vehicle. The sensor control module is also configured to determine, using information acquired by the at least one radar scan of the vehicle interior, at least one characteristic of a child car seat positioned in the interior. The sensor control module is also configured to compare the at least one determined characteristic of the child car seat with child car seat comparison information and, responsive to the comparison of the at least one determined characteristic with the child car seat comparison information, control an operation of the vehicle.

A vehicle includes a rail-mounted component and a restraint monitoring system. The rail-mounted component can include one or more restraints. The restraint monitoring system includes a restraint control module, an encoder-decoder module, and a rail-mounted component control module. The rail-mounted component control module can include a restraint deployment loop and a restraint diagnostic loop. The restraint deployment loop can include a deployment signal amplifier. The restraint diagnostic loop can include a diagnostic signal amplifier. In examples that include both the deployment signal amplifier and the diagnostic signal amplifier, the deployment signal amplifier and the diagnostic signal amplifier may be wired in parallel.

Disclosed is a system for controlling a vehicle safety device, the system including: a vehicle safety device configured to protect an occupant; a first occupant detection unit configured to detect a position of the occupant's movable body part; a second occupant detection unit configured to detect a position of the occupant's body part fixed to the safety device; a calculation unit configured to calculate information on the occupant's behavior in the event of a collision accident of a vehicle based on the position of the occupant's movable body part detected by the first occupant detection unit and the position of the occupant's body part fixed to the safety device detected by the second occupant detection unit; and a control unit configured to control an operation of the vehicle safety device for protecting the occupant based on the information on the occupant's behavior calculated by the calculation unit.

[Problem]

Provided is an airbag device capable of improving the restraining performance of an occupant by an airbag at the time of a collision.

[Resolution Means]

The airbag device includes a first airbag cushion part and a second airbag cushion part installed on each side of a seat of a vehicle, a first active vent provided in the first airbag cushion part and a second active vent provided in the second airbag cushion part, and a controller that controls the first active vent or the second active vent to open and the other to close when the first airbag cushion part and the second airbag cushion part are expanded and deployed.

A roof airbag system includes a roof airbag, a lifting mechanism, a collision sensor, memory, and a processor coupled to the memory. The roof airbag is provided at a roof portion of a vehicle, receives a supply of gas from an inflator and deploys toward an upper body side of a vehicle occupant sitting on a vehicle seat. The lifting mechanism is provided at a seat cushion side of the vehicle seat and lifts a thigh area of the vehicle occupant. A collision sensor detects a collision of the vehicle. The processor is configured to, when a seat back of the vehicle seat is tilted more than a predetermined angle to the seat rear side and the collision sensor detects a collision of the vehicle, control the lifting mechanism to lift the thigh area of the vehicle occupant and control operation of the inflator to deploy the roof airbag.

A vehicle occupant protection control device includes: a seat state detector configured to detect directions of first and second seats inside a vehicle; and a vehicle occupant protection controller configured to open at least one of a first bag body that is opened on a first side in a width direction of the first seat and a second bag body that is opened on a second side diagonal to the first side in a width direction of the second seat in a state in which the first seat faces the second seat when the seat state detector detects that the first seat faces the second seat and an impact on the vehicle is detected or predicted. A first vehicle occupant sitting on the first seat is pressed on the second side in accordance with the opening of the first bag body or a second vehicle occupant sitting on the second seat is pressed on the first side in accordance with the opening of the second bag body.

The invention describes a vehicle occupant restraint system (2) comprising a control unit and at least two restraint elements (8, 10) for the protection of lower extremities (6, 6′, 7, 7′) in the area of a footwell (4) of a vehicle of a vehicle occupant seated in a particular vehicle seat of the vehicle, wherein a first restraint element (8) is configured as a knee airbag module (12), wherein a second restraint element (10) is provided for mounting into the footwell (4) of the vehicle, especially in an area of the footwell (4) of the vehicle arranged in the vehicle longitudinal direction (x) ahead of the knee airbag module (12), wherein, in a situation of restraint, the control unit can differentiate between different given situations, wherein the given situation can be determined via a vehicle seat position and parameters relating to vehicle occupants, wherein, in the situation of restraint, when a situation is given in which the vehicle seat (5) is in a position shifted backwards, especially in a position shifted backwards compared to the standard position, and the vehicle occupant is a short and/or light person, the control unit only activates the foot airbag module (16) of the second restraint element (10).
