Delphi Automotive, TRW, Inc. and other suppliers are developing collision-avoidance systems that will allow automakers to add new safety features as the technology matures. TRW is developing a radar network called AC1000 that will detect oncoming vehicles from any direction. A radar unit at each corner monitors objects and transmits the data to a central computer. The system could automatically brake or prepare the airbags to deploy. Delphi is working on a similar system that would also incorporate cameras.
