A vehicle airbag control system includes an airbag module, a temperature detector and an electronic controller. The airbag module is for a vehicle. The airbag module has an airbag with a vent. The temperature detector configured to detect an ambient temperature of the vehicle. The electronic controller is programmed to control the airbag module between an active venting condition and a non-venting condition based on a detected result detected by the temperature detector. The vent is in an open state in the active venting condition. The vent is in a closed state in the non-venting condition.

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).

An airbag driving apparatus for a vehicle may include: a first acceleration sensor configured to sense acceleration of a vehicle; a collision sensor configured to sense an impact applied to the vehicle; an airbag controller configured to receive a first acceleration value and an impact value from the first acceleration sensor and the collision sensor, determine a collision state of the vehicle, and transmit an ignition command for driving an airbag; and a driving controller comprising a second acceleration sensor installed therein to sense the acceleration of the vehicle, and configured to determine a deployment possibility of the airbag based on a second acceleration value of the second acceleration sensor, receive the ignition command from the airbag controller, and output an airbag deployment signal to the airbag.

A method for triggering at least two safety functions from a predefined plurality of safety functions in a motor vehicle, including a) recognizing a trigger signal for one first safety function, and b) generating a trigger signal for at least one second safety function, if according to step a) the trigger signal for the first safety function has been recognized, the first safety function being of a first function type and at least one of the second safety functions being of a second function type differing from the first function type.

A method to arm an airbag, the method including determining, by a system device, that an arming condition for the airbag has been met; delivering a communication to a master device from the system device to inform the master device that the arming condition has been met; snooping the communication by an expansion device; and arming the airbag by the expansion device in response to snooping the arming condition.

A vehicle structure material strengthening system and a vehicle containing the same are described. The vehicle structure material strengthening system has at least one collision sensor, a processor, and a power supply. The collision sensor is suitable for being mounted on the vehicle. The processor is electrically connected to the collision sensor for receiving a collision signal from the collision sensor, and determines whether to transmit a power activation signal according to the collision signal. The power supply is electrically connected to the processor and the vehicle. When the collision signal is greater than or equal to a collision threshold, the processor transmits the power activation signal to the power supply, wherein the power supply transmits a circuit to the vehicle according to the power activation signal; or when the collision signal is less than the collision threshold, the processor does not transmit the power activation signal.

A vehicle airbag system is proposed. The vehicle airbag system includes: a front airbag mounted to a portion of a vehicle in front of a passenger and configured to be unfolded toward a front of the passenger; an upper airbag mounted to a portion of the vehicle above the passenger and configured to be unfolded toward the front of the passenger; a seat detector configured to detect a seating posture of the passenger; and a controller configured to control unfolding of the front airbag or the upper airbag on the basis of the passenger's seating posture detected by the seat detector.

An occupant protection device which can protect an occupant without delay is provided. An image taken by an imaging device is analyzed to judge whether there is an object approaching the subject car. In the case where a collision between the object and the subject car is judged to be inevitable, an airbag device is activated before the collision, whereby the occupant can be protected without delay. By using selenium for a light-receiving element of the imaging device, an accurate image can be obtained even under low illuminance. Imaging in a global shutter system leads to an accurate image with little distortion. This enables more accurate image analysis.

An assembly for a vehicle includes a vehicle roof and a panel rotatably connected to the vehicle roof. The panel is rotatable away from the vehicle roof from a stowed position to a deployed position. The assembly includes an airbag supported on the panel. The airbag is inflatable from the panel in a vehicle-forward direction when the panel is in the deployed position.
