Abstract

This paper describes experimental results and effectiveness of a Collision Warning System (CWS) as demonstrated on a driving simulator. The two key technological elements of the system are: (1) a path estimation algorithm, which is a method to determine the location of a preceding vehicle; and (2) a danger judgement algorithm which can predict collisions with preceding vehicles. The characteristic of the path estimation algorithm is that it uses variances of distances and azimuths to forward obstacles. This algorithm can also simultaneously estimate vehicle sideslip angle. The characteristic of the danger judgement algorithm is that it changes the critical headway distance when it detects the deceleration of a preceding vehicle. This algorithm can make quick and smart warnings. The evaluation of this system by the driving simulator shows the possibility that this algorithm can avoid collisions twice what the conventional one can.
