Abstract

The invention provides a car navigation system with navigation accuracy, which comprises a positioning module, a traffic information acquisition subsystem, a navigation module, a map module, a map matching module and a display module. The positioning module is used for acquiring a car position; the traffic information acquisition subsystem is used for predicting a traffic flow; the navigation module is used for planning a drive route according to the car position and the prediction results of the traffic flow; the map module is used for storing a city electronic map; the map matching module isused for matching the car position and the drive route as well as the stored city electronic map; the display module is used for displaying the car position and the drive route matched with the map.The car navigation system with navigation accuracy provided by the invention has the beneficial effects that when the car navigation system plans the drive route, a congested road can be automaticallyavoided, and the accurate navigation of the car is realized.

Description

technical field [0001] The invention relates to the technical field of vehicle navigation, in particular to a vehicle navigation system with accurate navigation. Background technique [0002] While the process of urbanization endows people with a modern life, it also brings many problems and challenges, such as air pollution, energy consumption, backward planning, traffic congestion, etc. Among them, the traffic problem has always been one of the main problems affecting urban development. The complexity of the urban road network and its surrounding space environment brings greater difficulty to the solution of urban traffic problems. [0003] The urban road network is a complex network system composed of road sections and intersections between road sections, and traffic flow is a traffic phenomenon attached to the road network, reflecting the process of moving vehicles moving along the road. Therefore, urban traffic flow is largely influenced by the road network. Based on...
