Active Control Retractor
The Active Control Retractor (ACR) is activated through data from active safety systems, such as the Electronic Stability Control or Brake Assist systems. It can also be triggered by data from other environmental sensors, such as radar that provides the relative speed and distance to the vehicles ahead.
ACR offers reversible pretensioning, and a parametric trigger algorithm and functional software.
Steering Torque Control
This system acts as the link between the stability control and electric steering controllers. The technology has three main functions: oversteer control; split-mu control; and agility control. During a split-mu situation (where there are two very different surfaces, such as ice and dry roadway or grass and roadway), ABS and ESC work with the steering system to help maintain vehicle stability. In an oversteer situation, steering torque is generated to encourage the driver to countersteer and ultimately respond to vehicle yaw in the most controlled fashion.

Lane Change Assist/Blind Spot Assist
TRW has used its expertise in sensor technology to develop a system that offers a field of view that covers most of the blind-spot area around a vehicle, at a range of 50m. If a moving object is detected within the specified zone, a warning signal is issued. Lane Change Assist features a fast reaction time for high-speed driving situations; the system is fully operational at speeds up to 250km/h.
Lane Departure Warning/Guidance
TRW's Lane Departure Warning and Lane Guidance systems use a forward-facing video camera mounted behind the rearview mirror to detect the lane markings on a highway and alongside many types of roadways.
If the driver unintentionally crosses a road lane marking or the edge of the road he receives a visual, audible or haptic warning to allow him to correct the situation. Haptic feedback options include a vibrating steering wheel that is activated when crossing lane markings. LDW is comparable to a virtual road rumble.
Rollover Prevention and Mitigation
TRW’s approach to countering vehicle body roll with minimum sacrifice to ride quality is based on Active Dynamic Control. Body roll reduction means not only better handling, but also reduced chance of rollover. Working with Electronic Stability Control, these systems combine to manage skids as well as control body roll.
Lane Departure Warning/Guidance
TRW's Lane Departure Warning and Lane Guidance systems use a forward-facing video camera mounted behind the rearview mirror to detect the lane markings on a highway and alongside many types of roadways.
Lane Departure Warning
This system is designed to help mitigate two types of situations: single vehicle road departures when a vehicle collides with an oncoming vehicle or one in an adjacent lane.
Height Adjuster
The TRW seat belt height adjusters are important not only as a comfort and convenience feature, but also to assist in the performance of the seat belt system by better matching the belt geometry to occupants of varying sizes. Most height adjusters are set manually by the occupant.
Buckle Pretensioners
TRW's pretensioner technologies are another element used to help manage occupant energy in a crash. Most pretensioners use a small pyrotechnic charge to help quickly remove slack, if present, from the seatbelt system and restrain the occupant earlier in the event.
Pretensioners can be integrated into the buckle or retractor and take up seatbelt slack using the retractor mechanism or by pulling the seat belt buckle downwards toward the vehicle floor.
TRW 4.0 Retractor Family
TRW's seat belt retractors offer a wide variety of options to enhance restraint performance. These retractors have advanced features including varying options of load limiting, pretensioning and even pre-crash pretensioning in the case of TRW's active control retractor.
