Abstract

The invention discloses an affixed vehicle line sound navigation device, which comprises a road modeling module used for establishing the corresponding network model to the road in the electronic map according to the factual road condition and establishing the topology relation drawings between the roads, an affixed vehicle line collocating module used for collocating the affixed vehicle line information at the affixed vehicle line on a network module established by the road modeling module, a sound navigation database used for storing sound information, a path layout module used for determining the driving path of the vehicle, a GPS positioning module used for determining the current position of the vehicle, a navigation sound module used for picking and playing the corresponding sound information from the sound navigation database, and a main control module used for transferring the navigation sound module to carry out sound navigation when judging that the front side of the currentvehicle position is affixed vehicle line according to the results of the path layout module and the GPS positioning module. Adopting the technical proposal, the invention can navigate more safely.

Description

technical field [0001] The invention relates to the field of navigation electronic maps, in particular to a voice navigation device for additional lanes. Background technique [0002] In the prior art, the navigation electronic map will perform voice navigation according to the actual lane guide line information at the intersection when planning the route and voice navigation. The traditional navigation electronic map treats the additional lane information in the same way as the general lane information. There is no distinction, and there is no problem in route planning, but in the actual driving process, additional lane information cannot be drawn on the navigation map, and users cannot predict the situation ahead in advance, leading to confusion in guidance and even traffic safety problems. The vehicle lane information refers to the information signs on urban roads used to indicate the direction of travel of vehicles in each lane. The vehicle lane information is generally ...
