Embodiment Construction

[0022] For speed limit information, it generally refers to traffic warning signs that limit the speed of vehicles in road traffic. It is generally a black Arabic numeral with a circular frame, as shown in Figure 1. The black Arabic numeral in the middle is 40, indicating the driving speed on the road. must not exceed 40 km / h.

[0023] As shown in Figure 2, the speed-limited road voice navigation device of the present invention comprises:

[0024] 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;

[0025] The speed limit road configuration module 1 is used to configure the speed limit information at the speed limit road on the network model established by the road modeling module;

[0026] Voice navigation database 2, used to store voice information;

[0027] Path planning module 3, used to determine the drivi...

Abstract

The invention discloses a speech navigation device of speed-limit road including the road modeling module used to set the network module in electric map according to the react road and set the topological map between the roads; the distributed module of speed-limit road used in distributing the speed-limit information at the speed-limit position of the network module on the road modeling module; the speech navigation data bank used to memory speech information; road programming module used to determine running path of vehicle; GPS location module used to determine the present position of vehicle; navigation speech module used to take out the speech information and play from the speech navigation data bank; main controlling module used to select the navigation speech module to navigate to determine the speed-limited road according to the road modeling module and GPS position module. Because of using the phonetic cue in speed-limited road, it can provide the navigation of more safety.

Description

technical field [0001] The invention relates to the field of navigation electronic maps, in particular to a voice navigation device for speed-limited roads. 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. Along with the national road construction planning and the occurrence of urban traffic accidents, more and more roads have begun to limit the speed of vehicles in order to control the incidence of traffic accidents. The existing voice navigation device does not have any information about the speed limit, which is not cond...
