Abstract

The invention discloses a road modeling module as a guidance electronic map displaying device, used for building the corresponding network module for the road in the electronic map according to the actual situation of road and building the topological relation graph between roads; a road property deploying module, used for granting public property or private property to the road in the network module according to the actual situation of road and storing in the guidance electronic map database; a path programming module, used for fixing the driving track of vehicle; a GPS positioning module, used for fixing the current position of vehicle; a displaying module, used for display the electronic map information around the current position of vehicle fixed by the path programming path and the GPS positioning module by making the road of private property. By adopting the road deploying module, the property of the road is deployed into public property or private property, which makes the displaying effect more accurate.

Description

technical field [0001] The invention relates to the field of navigation electronic maps, in particular to a navigation electronic map display device. Background technique [0002] With the continuous development of vehicle navigation system application technology, vehicle navigation hardware and software are becoming more and more mature, and navigation data information has been gradually improved. In the existing car navigation system, the road attributes of the navigation electronic map include attribute information such as "road name", "road grade", "road width" and "number of lanes". According to these attribute information, the navigation system can realize Vehicle navigation functions such as information query, map display, route planning, and route guidance have greatly promoted the development of vehicle navigation system technology, making the vehicle navigation system more convenient and practical. [0003] The prior art navigation electronic map display device di...
