Study on vehicle safety distance warning system

The paper presents a design of vehicle safety distance warning system. This system can measure distance between in front of vehicle (obstacle) and driving car and the system can calculate the safety distance of the driving car. And then a novel algorithm is proposed for to calculate the distance between driving cars is enough or not. If the driver doesn’t keep the safety braking distance with front of car (obstacle), it will warn driver to slow down the speed of car to avoid collision accident in the dangerous condition. The results of the experiment also presented to guarantee the function is work.
