TRW's Pre Crash Emergency Braking technology combines forward looking radar and video systems (Adaptive Cruise Control and Lane Departure Warning) to provide a very complete, accurate and real-time picture of the road ahead. Coupled with electronic stability control, these systems can be extended beyond mere warning systems to automatic emergency braking. If sensors detect a potential impact a certain amount of brake pressure is applied automatically and the brake system is readied to provide maximum brake boost immediately once the driver does engage the brakes. The reduced stopping distance helps to mitigate the effects of the potential accident. The Active Control Retractor can also be triggered prior to the actual impact thus improving the margin of safety for the occupants.   TRW's adaptive cruise control and collision warning systems monitor the road ahead   TRW's adaptive cruise control and collision warning systems sense an impending vehicle sending signals to the vehicle's braking system to prepare for emergency braking TRW's emergency braking begins. The brakes apply full pressure.
