【摘要】 我国汽车保有量迅速增加,汽车的速度也越来越高,驾驶的安全性成为交通的最主要问题。我国的公路交通事故的发生率,尤其是恶性事故。归纳起来,主要有以下几种:正面和侧面的碰撞以及追尾、翻滚等。据统计,侧面碰撞的几率很大,是正面碰撞的50%左右,居于碰撞事故的第二位。所以,汽车的侧向防撞预警系统就此产生。它是一个集车辆工程、人机工程、通信技术与计算机等多学科领域理论技术于一体的及其复杂系统。本文通过对车辆的安全性的问题的考虑,对汽车防碰撞技术进行了研究,目的是为我国汽车安全驾驶系统的研究提供理论及技术支持。论文通过对我国汽车技术的客观状况的分析,探讨了对车辆在换道和超车过程中的侧向防撞。论文概括了国内外车辆防撞系统现状,本系统与现在的实际需要相结合,提出了数学模型及设计方案。论文采用ATmega16作为系统的控制元件,应用超声波传感器作为测距传感器的侧向防撞预警系统。论文阐述了系统的设计构思以及每个单元模块的功能,通过对系统工作环境的分析,提出了系统软硬件设计的方案。更多还原

【Abstract】 Rapid increase in car ownership in China, more and more high-speed car, driving safety as the main traffic problems. Our incidence of road traffic accidents, especially fatal accidents. To sum up, mainly in the following categories: front and side and rear-end collision, roll, and so on. According to statistics, side impact has a large proportion, it is about 50% of the front impact,it is the second place of the collision.Therefore, the vehicle side collision warning system is produced. It is a set of vehicle engineering, ergonomics, communications technology and computer technology and other subjects in one field theory and complex systems. Based on the problem of vehicle safety considerations to study the vehicle anti-collision technology, our aim is to study auto safety driving system to provide theoretical and technical support. Paper through the objective analysis of the status of automotive technology,Discuss the lane changing and overtaking vehicles in the lateral process of the collision.Paper summarizes the status of domestic and foreign vehicle collision avoidance system, the system combines actual needs ,and propose the mathematical model and design.the paper used ATmega16 as the system’s control components, the paper use the ultrasonic sensors as the lateral distance sensor. Paper describes the design concept and function of each unit module, the work environment through the system analysis, system hardware and software design solutions.更多还原
