Forward Collision Warning System Based on THASV-II Platform

Abstract

This paper presents a forward collision warning system based on Tsinghua active safety vehicle platform, THASV-II. The system includes several modules to implement different functions including obstacle detection, data collection, information processing, warning signal generation, and human-machine interface display. In the collision warning algorithm design, a criterion named 'safety degree value (SDV)' is investigated to present the driver's estimation of the safety state. Car-following tests involving 40 driver subjects are conducted on the THASV-II platform and the algorithm is proposed with the test data. The system generates audio and visual warning information with several warning levels and the simulation shows that the warning output of the system is in accordance with driver's braking behavior.
