Evaluation and Improvement of Required Deceleration Algorithm in Frontal Collision Warning Systems

Different kinds of warning algorithms are used in the Frontal Collision Warning Systems (FCWS) for threat assessment, which are based on different kinds of kinematics measures of vehicles. In this paper, the authors discuss the required deceleration warning algorithm in two different situations, and consider a more complicated scenario. Based on field experiment data, the authors use an experienced driver's action which is denoted as "Real Acceleration" to evaluate the proposed algorithm's efficiency, and several other algorithms are evaluated for comparison. Furthermore, an improvement of the required deceleration algorithm is proposed. The threat of a lane-changing vehicle is also considered in the new algorithm.
