由于现代车辆中部署的传感器数量越来越多，车内无线传感器网络（ivwsn）最近在汽车行业受到了广泛关注，因为它们可以减少车内线束的数量。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是一个多功能平台，也可以支持其他车辆应用。本文讨论了一个应用实例，即侧盲区预警系统（SBZA），该系统能够监测车辆的盲区并及时向驾驶员发出警报，以防止碰撞。通过在两辆试验车上进行的真实实验，对基于ivwsn的SBZA系统的性能进行了评估。结果表明，该系统的检测率约为95%-99%，虚警率低于15%。与使用雷达或摄像机的商业系统相比，基于ivwsn的SBZA的主要优点是成本大大降低。
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%-99% detection rate with less than 15% false alarm rate. Compared with commercial systems using radars or cameras, the main benefit of the IVWSN-based SBZA is substantially lower cost.
