Multi-Sensor Deep Integration for Next Generation Land Vehicle Positioning and Navigation

点击翻译按钮获取中文摘要

Present land vehicle positioning and navigation (POS/NAV) systems provide drivers with route guidance information relying mostly on the Global Positioning System (GPS). They have become indispensable in many of the new automobile models, and their design concepts have evolved to include functionalities that make them more than just a vehicle location and map displaying system. Future land vehicle POS/NAV technology will integrate number of sensors and systems to increase the driving efficiency and enhance both driver’s experience and safety. In addition, intelligent transportation systems (ITS) require a POS/NAV system that can provide sub-meter accuracy to enable efficient operation of newly emerging ITS technologies including cooperative vehicles for improved urban mobility and for cooperative collision avoidance.
