As part of the integrative project related to GPS-based safety, TRW is working on an integration of advanced belt systems like the Active Control Retractor 2 and the Active Buckle Lifter, featuring global navigation satellite systems and enhanced road maps. While current ACR2 and ABL functions for dynamic support make use of vehicle dynamics data and, therefore, react when the vehicle already is in a curve, the integration of GPS and map information allows a foresighted and curve-predictive control of these functions. The results are earlier and gentler belt system activation, maintained belt support in curve combinations and additional position-adapted comfort features.
