Embodiment Construction

[0021] For height limit information, it generally refers to traffic warning signs that limit the height of vehicles in road traffic. As shown in Figure 1, the word "3.5m" in the center indicates that the road here has a height limit of 3.5 meters for vehicles.

[0022] As shown in Figure 2, the height-limited voice navigation device of the present invention includes:

[0023] The road modeling module 7 is used to set up its corresponding network model for the road in the electronic map according to the actual road situation and establish a topological relationship diagram between the roads;

[0024] The height limit configuration module 1 is configured to configure height limit information at the height limit on the network model established by the road modeling module;

[0025] Voice navigation database 2, used to store voice information;

[0026] The path planning module 3 is used to determine the driving path of the vehicle according to the starting point and the end point...

Abstract

The invention discloses a voice guidance device at the limited height, which comprises a road modeling module used for building the corresponding network module to the road in electronic map and building the topology relationship graph among roads; a deploying module at the limited height, used for deploying height limiting information on the network module built by the road modeling module; a voice guidance database, used for storing voice information; a path programming module, used for fixing the driving track of vehicle according to the initial point and the end point; a GPS positioning module, used for fixing the current position of vehicle; a guidance voice module, used for taking out the corresponding voice information from the voice guidance database to play; a main control module, used for assigning the guidance voice module to conduct voice guidance when judging the front of the current position of the vehicle is the limited height according to the path programming path and the GPS positioning module. By adopting the guidance with the road lighting information in the invention, safer guiding can be achieved.

Description

technical field [0001] The invention relates to the field of navigation electronic maps, in particular to a voice navigation device for height-limited places. Background technique [0002] The main purpose of GPS (Global Position System, Global Positioning System) car navigation system is to provide vehicle drivers with detailed navigation services from the starting point to the destination, and the navigation voice prompts when the vehicle reaches the intersection are the one of the key factors. [0003] Most of the existing voice navigation devices can provide prompt information such as turning, but this is far from satisfying the needs of modern society. With the national road construction planning and the construction of more and more overpasses or tunnels, the demand for height limit has become increasingly prominent. The height limit refers to the limited maximum passing height used to limit traffic facilities such as overpasses. The height limit information refers ...
