One of the prime examples of active/passive safety integration already available is the integration of an Adaptive Cruise Control (ACC) with TRW's Active Control Retractor (ACR) seat belt system. Once a potentially dangerous situation is sensed, the ACR is activated for limited or full restraint depending on the situation.

Active Control Retractor

The Active Controlled Retractor (ACR) allows reversible belt retraction in critical situations. It can be activated using data from active safety systems, such as the Electronic Stability Control or Brake Assist systems. It can also be triggered by data from environmental sensors, such as radar that provides the relative speed and distance to the vehicles ahead.

Enhancing Occupant Safety

One more step regarding the increase of occupant safety by system integration is the integration of the ACR with TRW´s Automatic Emergency Braking (AEB). As the ACR can be activated prior to an automatic brake actuation, the efficiency of belt pretensioning increases.
