The Different Driving Phases – Pre-Crash
Before an accident (Pre-crash): preparation
Reducing the speed of collision using an emergency brake assist can decisively minimize the risk of injury. During a pre-crash situation, additional protective functions like seat belt tensioners are initiated to prepare the vehicle and its occupants for a crash. If a crash is unavoidable, pre-crash information on the crash severity and crash type results in situation-dependent deployment of the restraint systems, in order to offer occupants a maximum of protection.
Emergency Brake Assist (EBA)
If an accident is unavoidable the EBA will autonomously brake the car in order to avoid the impact or mitigate its consequences.

Airbag Support (Vehicle-2-X)
Prior to a crash, the transmission of the vehicle mass takes place, in order to optimize the deployment strategy of the airbag, according to the crash severity.

Activation of the Reversible Seatbelt Pre-Tensioners
With an accident imminent, the reversible seatbelt pre-tensioners are activated.

Advanced and Active Occupant Safety
Based on vehicle surrounding sensors and vehicle state observing in the ESC, an adapted airbag deployment strategy is applied to the assessed critical driving situation.
