CNET GLOSSARY: Terms for the techie
collision warning system
A collision warning system tells the driver when it detects objects in the path of the vehicle, such as a vehicle slowing down ahead of you. Some systems also apply braking to help avoid a collision. The collision warning system has several advantages over human performance in helping to avoid collisions, including constant monitoring of the road ahead and reacting quickly and automatically to danger.
The system is most often incorporated into vehicles with radar- or laser-based adaptive cruise control. A camera may also be used for additional input. The combined information provides a reliable picture of the road and is especially helpful in conditions with poor visibility.
