Self Adapting Vent
As the airbag inflates, the occupant position and distance sensors help determine the force of deployment. Then, a pyrotechnic actuator initiates a vent mechanism within the mounting plate of the airbag module to adjust the performance. In some circumstances, the position of the occupant to the airbag suggests that more gas be allowed to escape from the module, allowing the energy to dissipate more quickly. This technology provides a solution for helping to meet OOP (out-of-position) requirements of FMVSS 208 while using a single-stage inflator.
Knee Airbag
The compact knee airbag module uses TRW’s SHI2 inflator technology, as well as an airbag that covers the potential knee impact area at the lower part of the instrument panel. This setup helps to provide harmonized occupant kinematics and positioning while reducing and/or balancing chest and lower limb loads. The module features a 2D pillow airbag with internal tethers designed to yield an effective deployment and help reduce tibia loads during a crash. The housing can be configured to suit most vehicle space constraints.
Load Limiters
Progressive Load Limiter
The system uses two load limiting devices. The basic load is due to the torsion bar, and the progressive load comes from a cutter within the spool assembly. The cutter shears off material from a spiral ridge within the spool assembly. The cross-sectional shape of the spiral defines shear area, and thus the progressive behavior of the load limiter. The progressive range goes up to 3kN and a 340° rotation of the spool. This limiter is used for rear-seat applications and fulfills elongation requirements in FMVSS 209 and ECE R16.
Semi-Active Roll Control
Based on the Active Dynamic Control concept, TRW's Semi-Active Roll Control (SARC) system offers similar, albeit slightly reduced, anti-roll compensation at a lower cost.
Links and Tie Rods
TRW offers a wide variety of links and tie rods that are key components to TRW's Steering and Suspension portfolio. The link and tie rod product offerings include stabilizer links; tie-rod ends and assemblies; front and rear toe links; center links; and idler and pitman arms for vehicle manufacturers' original equipment and service needs.
Control Arms
Control arms are typically the interface between the wheel-end assembly and the chassis, allowing for independent vertical travel of the wheel. TRW's control arms and links can help improve vehicle weight, fuel economy, emissions, energy savings, driving safety, ride, comfort and NVH (noise, vibration and harshness) characteristics. TRW's portfolio includes upper and lower control arms for both front and rear suspensions. TRW offers full service capabilities to support all passenger car and truck applications.
Ball Joints
The ball joint is a rotating, swiveling coupling that is typically the interface between the control arm and knuckle in a vehicle's suspension. The ball joint serves as the pivot point between the tire and the suspension. TRW Automotive offers many designs suitable for a wide variety of applications. This portfolio includes low-cost to high-performance designs that satisfy different customers' needs. TRW also continues to develop next-generation designs to reduce cost and weight, while maintaining or improving performance.
Weight Sensing System
TRW continues to lead the way in the design, engineering and development of advanced adaptive restraint systems, such as Weight Sensing systems, for occupant classification and detection.
Park Assist
The TRW Park Assist system combines electrically powered steering with environmental sensing to aid drivers during parallel parking maneuvers. The system uses short-range radar sensors to evaluate the length of the parking slot. From this information, the steering trajectory is calculated and the proper steering angle is automatically chosen. The driver monitors the steering and operates only the throttle and braking system while the parking maneuver is completed.
Adaptive Cruise Control with Stop & Go
TRW is building on its innovative driver assist product portfolio by adding a traffic jam assistant Stop & Go functionality to its Adaptive Cruise Control (ACC) system. Using the ACC long-range radar, Traffic Jam Assistant allows the ACC vehicle to follow a target to stop and, upon driver command, follow that target in traffic jam situations. An additional sensor will be used (e.g. camera) to cover a nearer but wider field in front of the vehicle. Automatic Go will be enabled, to comfortably follow the target vehicle in a traffic jam situation.
