摘要
随着智能交通系统（ITS）的不断发展,对智能车的控制技术的研究也日益重视。设计了基于电磁场检测的循线智能车系统核心处理器为MC9S12DG128芯片,利用电磁场信号检测方法识别智能车跑道,这一方法极大地提高了智能小车的抗干扰性。智能车在行驶过程中根据系统对路径磁场信号的检测、处理情况采取相应的控制算法实现自动循迹,且在自主循线行驶的过程中,当遇到传感器盲点时可以主动找正,实时判断车体的状态且及时调整。通过测试得出该系统的正常运行的一系列指标,可为汽车电子智能导航技术提供一个新的借鉴方法。
As the study of intelligent transportation system（ITS）is becoming more and more attention,the control of intelligent vehicle technology is also becoming research hot.The following intelligent car system based on electromagnetic field detection is designed in this paper.MC9S12DG128 is the core processor of this system which identifies the runway by the electromagnetic field detection.It greatly improves the model car＇s anti-interference and perspectiveness.The smart car system chooses the corresponding control algorithm is adopted to realize automatic tracking according to the magnetic field signal detection and processing of the runway when driving on the runway.The smart car can independent cycle line at the most appropriate speed,and is able to adapt itself when meeting the sensor blinding spots.So the research for automotive electronic intelligent navigation technology provides a new method for reference.
