摘要

Autonomous navigation of vehicle running with GPS receiver is an important study aspect of future vehicle navigation field. This paper introduces a self-study type navigation method. In this method, real-time receiving for position information of vehicle running track is carried out by embedded GPS receiver, and linearized processing with unitary regression algorithm for discrete position information received by GPS receiver is carried out by microprocessor, then linear correlation of track information is judged by linear correlation coefficient and track information is divided into sections based on degree of linear correlation. Position information of running track is obtained by self-study and the formed autonomous navigation track information is of high navigation accuracy and predictability of front direction. This method needs no professional GIS technology to support and is of excellent flexibility.
