A method of determining a critical vehicle event. The method includes receiving vehicle speed data and airbag status data at a remote server. The method further includes deriving, at the remote server, a vehicle deceleration from the vehicle speed data. The airbag status data is analyzed at the remote server to determine whether an airbag on the vehicle has deployed, wherein the analyzing of the airbag status data occurs when a magnitude of the derived vehicle deceleration is above a preset magnitude. The method additionally comprises generating a critical event confirmation signal when the airbag status data reveals deployment of the airbag on the vehicle.

A device and a method for controlling autonomous driving are provided The device includes non-transitory memory storing instructions executable to control an autonomous driving; and a processor configured to execute the instructions to determine whether a collision has occurred using an acceleration sensor mounted on an airbag control unit during the autonomous driving, determine a collision direction based on a change in acceleration of three axes obtained by the acceleration sensor, and perform an emergency action by controlling at least one of longitudinal direction travel or transverse direction travel based on the collision direction.

Airbag deployment data is collected using a plurality of sensors located along a line of weakening formed in a vehicle interior panel. The sensors are configured to provide information pertinent to separation of adjacent portions of the panel from each other as a function of time at a plurality of locations along the line of weakening. Each sensor is attached to the panel so that the sensor crosses the line. The relative time at which a conductive part of each sensor breaks is recorded and provides useful information about airbag door behavior during airbag deployment.

A method for detecting airbag deployment includes operating a plurality of sensors of the mobile device disposed in a vehicle during a drive to obtain a plurality of measurement signals, determining a change in at least one measurement signal of the plurality of measurement signals and that the change exceeds a first threshold. In response to determining that the change exceeds the first threshold, obtaining a pressure measurement signal from a pressure sensor of the plurality of sensors, determining a derivative of the pressure measurement signal, and determining that the derivative of the pressure measurement signal exceeds a second threshold. In response to determining that the derivative of the pressure measurement signal exceeds the second threshold, detecting a deployment of a vehicle airbag based on the change in the at least one measurement signal exceeding the first threshold and the derivative of the pressure measurement signal exceeding the second threshold.

A multi-frontal airbag for a vehicle and an airbag deployment system using the same are provided. The system includes a sensing unit that collects the state information of a seat. A first airbag module is disposed within the vehicle and includes a first cushion that is deployed toward the front of a passenger and a first inflator that supplies gas to the first cushion. A second airbag module is disposed within a roof above the passenger and includes a second cushion that is deployed downwards and a second inflator that supplies gas to the second cushion. A controller receives the state information of the seat from the sensing unit, and adjusts the operations or operation timings of the first airbag module and the second airbag module.

A method for operating a seat belt system (10) for an occupant (12) in a vehicle (14) comprises a belt webbing for restraining the occupant (12), a belt buckle (26) and a sensor (28) for sensing the webbing extension. The method initiates a reaction when the webbing extension exceeds a threshold which takes the minimum webbing extension after the closing of the belt buckle (26) into account.
