Precrash system
From Wikipedia, the free encyclopedia
A precrash system is an automobile safety system designed to reduce the damage caused by a collision. Most use radar sensors to detect an imminent crash and respond by tightening the seat belts, boosting brake pressure, and even applying the brakes. Some also monitor the rear of the vehicle and can adjust the head restraints ("headrests") to reduce the risk of whiplash injuries. The "Pre-Safe" system employed in the new Mercedes-Benz S-Class can also close any open windows and the sunroof if necessary.
Precrash systems are currently available on the following vehicles:
- Acura RL ("Collision Mitigation Avoidance System")
- Infiniti QX56
- Lexus LS ('Pre-Crash' - 2007 model includes rear monitoring)
- Lexus IS
- Mercedes-Benz S-Class ('Pre-Safe')
Nissan Motors is reportedly developing a new "magic bumper" system which raises the accelerator pedal if it senses an impending collision. Once the driver lifts off the pedal, the system then automatically applies the brakes.
