摘要
Abstract
Relatively shorter dynamical vehicle space which results from the disability of driver on estimating is the main reason for traffic rear-end?collision?accidents. Therefore, the essential approach for reducing rear-end collision accidents is improving drivers' ability of estimating dynamical vehicle space. Based on the two-step detection, this paper proposes the detection theory to establish an alarming system for dynamical vehicle space. By transmitting and receiving Frequency-Wave with two step, the real-time speed of the front car and the dy-namical vehicle space (short for DVS) between the two vehicles can be detected, and the theoretic safety space (short for TSS) can be calculated. By comparing the DVS and the TSS, the alarming system can remind the driver with warming. By improving drivers' ability of estimating dynamical vehicle space, this alarming system theory can effectively contribute to avoiding rear-end collision accidents.关键词
