Abstract

The invention discloses an embedded onboard combined navigation system based on dynamic traffic information, and relates to the field of intelligent electronic equipment of automobile assistant driving. The system consists of an embedded onboard information device 1 which is connected with a GPS/DR combined navigation module 2, a map matching module 3, a dynamic traffic induction module 4, a state identifying module 5, an onboard multimedia module 6 and a wireless data communication module 8 respectively, and an onboard information communication module 7, a dynamic traffic information module 9 and a software module which are assistant. The system adopts a combined Kalman filtering method to fuse positioning system information of a GPS positioning module and a DR positioning module so as to acquire optimal combined positioning data; and then the combined positioning data are sent to a CPU to be displayed or matched with a GIS database which is an electronic map, and the processed longitude and latitude data with high precision are output for users to use. The system can intuitively display information such as current position, time, speed and the like, and simultaneously provides accurate and quick dynamic navigation service.

Description

technical field [0001] The invention belongs to the field of intelligent electronic equipment for automobile auxiliary driving, in particular to an embedded vehicle integrated navigation system based on dynamic traffic information. Background technique [0002] Intelligent transportation system is mainly used to solve the problems of traffic congestion, road blockage, traffic safety and coordination of traffic and environment in today's world. The intelligent vehicle automatic navigation system is an important part of the intelligent transportation system.
