Considering the deficiency of the presently autonomous vehicle navigation terminal on dynamic updating of map data and reception of real-time traffic information,this paper presents the design options,which is based on the thought of combining the network with the autonomous navigation.

Implementation of echo cancellation in application of vehicle multimedia navigation terminal

In order to manage and store Point of Interest(POI) data of navigation E-map effectively in embedded navigation terminal with limited resources,based on Berkeley DB,this paper presents a block-oriented compression method for efficiently storing massive Point of Interest records on the embedded navigation terminal with limited resources.

The Control System of an Embedded Vehicle Terminal;

Research of GPS vehicle terminal communication technology based on GPRS;

The Design and Realization of Embedded Vehicle Terminal Based on GPS/GPRS;

The vehicle navigation system was constituted by three parts:navigation and control center,vehicular terminal and GPRS communication network.

However, it is hard to collect the data from vehicular terminals on the shuttle buses efficiently, because the present acquisition method depends on manual labor, which is.

After building the model of public transport network,the road traffic situation and corresponding traveling time are speculated according to dynamic data collected by GPS vehicle terminals,and then the bus arrival time is predicted.
