The Research for Mechanism of Vehicle Rear-End Collision Avoidance System

Abstract

In this paper, vehicle rear-end collision avoidance system is discussed and studied. Mathematical model is established to get the critical safe distance between vehicles with different velocity. The ranging sensor measures the distance between the two vehicles, and then the CPU compares it with the critical safe distance. If collision may occur, the system can remind the driver of adopting right measure by system warning of voice and light.
