摘要
随着汽车主动安全性要求的不断提高,采用更为有效的测试手段准确监控汽车的各种运动状态参数,获得良好的运动稳定性已越来越受到人们的重视。将GPS技术应用于汽车运动状态实时监控中。构建了GPS硬件系统;研究了基于ARM的GPS接收机的数据提取及处理的软件实现方法;由运动学的理论知识推导出汽车运动状态的理论公式;并经试验数据模拟,结果表明该系统可实现对汽车运动状态的连续监控。
More and more importance has been attached to the vehicle motion stability with the gradual enhancement of the active safety. In this paper, GPS technique was introduced into the research of real-time monitoring system, and an embedded OS to monitor the state parameters related to the vehicle was designed. At the initial, the extracting and processing of the data of GPS receiver based on ARM by software was discussed; then, the kinematics theory was applied to deduce the theoretical formula of the vehicle motion stability. Simulated by experiment data, it can realize successive monitor of the motion state of the vehicle.
