Ford alert system could save the lives of tired drivers

摘要

Tired drivers cause thousands of accidents each year, so Ford's Driver Alert safety system could be a life-saver. Driver Alert analyses driver performance and issues a warning if there are signs of drowsiness or erratic steering. The system comprises a small forward-facing camera connected to an on-board computer, which is trained to identify lane markings on both sides of the vehicle. The computer compares where the car should be positioned relative to the lane markings, and where the vehicle actually is. If the difference is significant, a warning is issued.
