Continental has recently successfully developed a Collision Acoustic Airbag Sensor System (CISS) that controls the launch of the airbag in the most accurate manner in the event of a collision in a vehicle to provide maximum protection for the vehicle occupants. The characteristics of the sound caused by the collision allow the CISS system to detect the occurrence of a collision and its severity, and can occur in a faster and more reliable manner in different collision situations. Collision accidents are distinguished. Therefore, even in very serious car accidents, the system can make the decision to release the airbag start-up insurance system more quickly, so that the vehicle occupants receive the maximum degree of reliable protection and subject their body to a minimum (airbag) tension. Shock.

The severity of the collision can be detected earlier
In a serious crash, the airbag safety system must respond within a fraction of a second; in the event of a frontal collision, the airbag safety system has a reflection time of only 10-40ms. Is the collision so serious that it is necessary to open the airbag? Or do you not need to open the airbag at all? In addition, are other passive safety devices such as collisional collapse zones and seat belts sufficient to protect the safety of the occupants? Or, the extent of the collision is so fierce that the airbag detonator is needed to open the airbag at the fastest speed? Or is there time to open the airbag in two stages? (The advantage of a two-stage start-up is that it allows the occupant to experience less tension shocks).
All of the above are induced by sensors that measure the deceleration rate of the vehicle. The collected data is analyzed by the airbag central control unit. The goal is to ensure that the sensor is so sensitive that the vehicle's degree of deformation can be registered as an important additional accident parameter. The CISS system makes this requirement possible because the responsive structural acoustic response sensor actually covers the entire range of the front end of the vehicle, so it generates very large amounts of data very quickly, no matter how the vehicle collides directly with the obstacle. Used to assess the severity of an incident.
When the vehicle collides with an obstacle, the CISS system records the speed at which the engine compartment or body is deformed, and the speed and intensity of structural acoustic wave propagation at this time. A sophisticated signal evaluation system uses specially developed calculation methods to analyze and assess collision accidents and will make the final decision on whether to activate the airbag and at what strength. In addition, the technology can be integrated with the airbag control unit, saving both cost and significant performance.
