基于车载无线传感器网络的盲区报警系统
A Blind Zone Alert System based on Intra-vehicular Wireless Sensor Networks
摘要：
由于现代车辆中部署的传感器数量越来越多，车载无线传感器网络（IVWSNs）最近在汽车行业受到了广泛关注，因为它们可以减少车辆内部的线束数量。通过去除电线，汽车制造商可以减轻车辆的重量，提高发动机性能，燃油经济性和可靠性。除了这些直接的好处，IVWSN是一个多功能的平台，也可以支持其他车辆应用。本文讨论了一个被称为侧盲区警报（SBZA）系统的示例应用，该系统监视车辆的盲区并及时提醒驾驶员以防止碰撞。基于IVWSN的SBZA系统的性能进行了评估，通过两个测试车辆上进行的真实实验。我们的研究结果表明，该系统可以达到约95%至99%的检测率小于15%的误报率。与使用雷达或相机的商业系统相比，基于IVWSN的SBZA的主要好处是成本大大降低。
英文摘要：
Due to the increasing number of sensors deployed in modern vehicles, Intra-Vehicular Wireless Sensor Networks (IVWSNs) have recently received a lot of attention in the automotive industry as they can reduce the amount of wiring harness inside a vehicle. By removing the wires, car manufacturers can reduce the weight of a vehicle and improve engine performance, fuel economy, and reliability. In addition to these direct benefits, an IVWSN is a versatile platform that can support other vehicular applications as well. An example application, known as a Side Blind Zone Alert (SBZA) system, which monitors the blind zone of the vehicle and alerts the driver in a timely manner to prevent collisions, is discussed in this paper. The performance of the IVWSN-based SBZA system is evaluated via real experiments conducted on two test vehicles. Our results show that the proposed system can achieve approximately 95% to 99% detection rate with less than 15% false alarm rate. Compared to commercial systems using radars or cameras, the main benefit of the IVWSN-based SBZA is substantially lower cost.
