基于智能手机的车辆碰撞系统研究

Research on Vehicle Collision System based on Smartphone

为提高道路安全,人们研发了许多防撞车预警系统。笔者提出一种基于智能手机的防撞车预警系统(SCWS),它克服了现有防撞车预警系统的局限性,如高安装成本、要求较高的市场渗透率,以及没有考虑到交通动态。本系统在实践中具有巨大潜力,它能发挥令人满意的性能,且仅需要较低的市场渗透率。同时,由于利用了普遍的智能手机,它的安装成本也非常低。

For improvement of road safety,many collision-warning systems are developed.The author propose smartphone-based Collision Warning System(SCWS)that overcomes the limitations of existing collision warningb systems such as high installation cost,requirement of high market penetration rate,and the lack of consideration of traffic dynamics.Therefore,we just require a low market penetration rate and low installation cost by using the wide spr ead smartphone.
