A Blind Zone Alert System based on Intra-vehicular Wireless Sensor Networks

摘要

Due to the increasing number of sensors deployed in modern vehicles,Intra-Vehicular Wireless Sensor Networks (IVWSNs) have recently received a lotof attention in the automotive industry as they can reduce the amount of wiringharness inside a vehicle. By removing the wires, car manufacturers can reducethe weight of a vehicle and improve engine performance, fuel economy, andreliability. In addition to these direct benefits, an IVWSN is a versatileplatform that can support other vehicular applications as well. An exampleapplication, known as a Side Blind Zone Alert (SBZA) system, which monitors theblind zone of the vehicle and alerts the driver in a timely manner to preventcollisions, is discussed in this paper. The performance of the IVWSN-based SBZAsystem is evaluated via real experiments conducted on two test vehicles. Ourresults show that the proposed system can achieve approximately 95% to 99%detection rate with less than 15% false alarm rate. Compared to commercialsystems using radars or cameras, the main benefit of the IVWSN-based SBZA issubstantially lower cost.
